Risks Relating to Business Operations in Emerging Markets

Emerging markets such as the Russian Federation, Ukraine and other CIS countries are subject to greater risks than more developed markets, including significant legal, economic, tax and political risks.

        Investors in emerging markets such as the Russian Federation, Armenia, Ukraine, Turkmenistan, Kyrgyzstan, Uzbekistan and other CIS countries should be aware that these markets are subject to greater risk than more developed markets, including in some cases, significant legal, economic, tax and

5

Table of Contents

political risks. Investors should also note that emerging economies such as the economies of the Russian Federation, Ukraine and other CIS countries are subject to rapid change and that the information set out herein may become outdated relatively quickly.

        Global financial or economic crises or even financial turmoil in any large emerging market country tend to adversely affect prices in equity markets of most or all emerging market countries as investors move their money to more stable, developed markets. Over the past few years, the Russian equity markets have been highly volatile, principally due to the impact of the global economic slowdown resulting from various factors, including the European sovereign debt crisis, the Chinese economic decline and the dramatic fall in oil prices, as well as the current crisis in Ukraine and deteriorating conditions of the Russian economy. As has happened in the past, financial problems such as significant ruble depreciation, capital outflows and a decrease in other leading economic indicators or an increase in the perceived risks associated with investing in emerging economies due to, inter alia, geopolitical disputes such as the current crisis in Ukraine, could dampen foreign investment in Russia and adversely affect the Russian economy. In addition, during such times, businesses that operate in emerging markets can face severe liquidity constraints as funding sources are withdrawn. Furthermore, in doing business in various countries of the CIS, we face risks similar to (and sometimes more significant than) those that we face in Russia and Ukraine. For example, see "—Legal Risks and Uncertainties—The inability of MTS-Turkmenistan to sustain its operations in Turkmenistan on commercially acceptable terms or at all may adversely affect our business, financial condition and results of operations," and "—The inability of our subsidiaries in the countries in which we are present to maintain control over their operations and assets may adversely affect our business, financial condition and results of operations." Accordingly, investors should exercise particular care in evaluating the risks involved and must decide for themselves whether, in light of those risks, their investment is appropriate. Generally, investment in emerging markets is suitable for sophisticated investors who fully appreciate the significance of the risks involved and investors are urged to consult with their own legal and financial advisors before making an investment in our securities.

Risks Relating to Our Business

The telecommunications services market is characterized by rapid technological change, which could render our services obsolete or non-competitive and result in the loss of our market share and a decrease in our revenues.

        The telecommunications industry is subject to rapid and significant changes in technology and is characterized by the continuous introduction of new products and services. The mobile telecommunications industry in Russia is also experiencing significant technological change, as evidenced by the introduction in recent years of new standards for radio telecommunications, such as Wi-Fi, Worldwide Inter-operability for Microwave Access ("Wi-Max"), Enhanced Data Rates for Global Evolution ("EDGE"), Universal Mobile Telecommunications System ("UMTS"), and Long Term Evolution ("LTE"), as well as ongoing improvements in the capacity and quality of communications, shorter development cycles for new products and enhancements and changes in customer requirements and preferences. Such continuing technological advances make it difficult to predict the extent of the future competition we may face and it is possible that existing, proposed or as yet undeveloped technologies will become dominant in the future and render the technologies we use less profitable or even obsolete. New products and services that are more commercially effective than our products and services may also be developed. Furthermore, we may not be successful in responding in a timely and cost-effective way to keep up with these developments. Changing our products or services in response to market demand may require the adoption of new technologies that could render many of the technologies that we are currently implementing less competitive or obsolete. To respond successfully to technological advances and emerging industry standards, we may require substantial capital

expenditures and access to related or enabling technologies in order to integrate the new technology with our existing technology.

We face increasing competition in the markets where we operate, which may result in reduced operating margins and loss of market share, as well as different pricing, service or marketing policies.

        The wireless telecommunications services markets in which we operate are highly competitive, particularly in Russia and Ukraine, where mobile penetration exceeds 100%. We also face increased competition in our cable TV and fixed line business, while the market for fixed line communications services in Russia is rapidly evolving and becoming increasingly competitive. Competition is generally based on price, product functionality, range of service offerings and customer service.

        Generally, increased levels of competition, including from the potential entry of new mobile operators, government-backed operators, mobile virtual network operators and alternative fixed line operators in the markets where we operate, as well as the strengthening of existing operators, increased use of Internet protocol telephony and other services, provided by the internet, may adversely affect our ability to increase the number of subscribers. This in turn could result in reduced operating margins and a loss of market share, as well as necessitating different pricing, service or marketing policies, which may have a material adverse effect on our business, financial condition and results of our operations.

Competition in the Russian market

        Our principal wireless competitors in Russia are Public Joint Stock Company "Vimpel Communications" or "VimpelCom" (formerly Open Joint Stock Company "Vimpel Communications") and Public Joint Stock Company MegaFon or "MegaFon" (formerly Open Joint Stock Company "MegaFon"). We also face competition from several regional operators as well as from the fourth federal cellular operator established on the basis of Tele2 Russia and mobile assets of Public Joint Stock Company Long-Distance and International Telecommunications "Rostelecom" or "Rostelecom" (formerly Open Joint Stock Company "Rostelecom").

        In addition, on April 1, 2011, the Russian government completed the reorganization of state-controlled telecommunications companies Svyazinvest Telecommunications Investment Joint Stock Company ("Svyazinvest"), and Rostelecom. As a result, Rostelecom is currently the largest fixed-line operator.

        In October 2010, Sistema and Svyazinvest entered into an exchange transaction, upon completion of which, Svyazinvest obtained control over 100% of the share capital in Sky Link, Sistema acquired the 23.33% stake in MGTS controlled by Svyazinvest and Comstar transferred 25% plus 1 share in Svyazinvest to Rostelecom for cash consideration of 26 billion rubles. Sky Link is a Moscow-based code division multiple access ("CDMA") operator holding GSM licenses for a majority of Russian regions. In July 2012, Rostelecom acquired 100% of Sky Link which at the time of this acquisition held licenses in 76 Russian regions covering more than 90% of the total Russian population. In addition, Rostelecom won tenders for 39 out of 40 licenses to provide fourth-generation ("4G") wireless services within the 2.3-2.4 GHz frequency band and in November 2011 received permission from the Ministry of Defense to use the allotted frequencies for the creation of a 4G network.

Table of Contents

        On December, 30, 2013 shareholders of Rostelecom approved a reorganization plan which led to the spin-out of its mobile business into RT-Mobile Ltd. RT-Mobile Ltd's business was contributed as capital for a new joint venture concluded between Rostelecom and Tele2 Russia, under the name of "T2 Rus Holding," later reorganized into "T2 RTK Holding." On February 6, 2014, Tele2 Russia and Rostelecom signed an agreement on integration of mobile assets on the basis of LLC "T2 RTK Holding."

        On August 6, 2014, it was declared that Tele2 Russia and Rostelecom closed the deal on integration of mobile assets. Therefore, the companies ended legal procedures on setting up a federal mobile operator on the basis of Tele 2 Russia that provided telecommunication services to over 38 million subscribers in more than 60 regions.

        In October 2015, joint venture, LLC "T2 RTK Holding" launched its network for commercial use in the Moscow region. The company is currently one of the important players in the mobile telecommunications market with market shares in Russia and in Moscow of 14% and 0.2%, respectively, as of September 30, 2015, according to AC&M-Consulting. Should further expansion of Tele2 continue it might materially adversely affect our business, financial condition and results of operations.

        In addition, mass media previously reported that Antares Group was trying to obtain extra bands for development of a fourth generation network (LTE) in the 1900 MHz range. In case Antares Group is granted extra frequencies in the future, this may lead to the establishment of a new LTE operator in Russia and increased competition in the data transmission services market.

        According to TMT Consulting, Rostelecom controls 70% of all fixed line telecommunications services in Russia. The emergence of Rostelecom as an integrated nationwide provider of fixed line local and long distance communications services as well as its reorganized business holdings in mobile communications services may significantly increase competition in our markets. In particular, a new mobile operator involving this state-controlled group may receive favorable pricing terms to interconnect from the regional fixed line operators within its group, putting us at a competitive disadvantage. See also "—If we cannot interconnect cost-effectively with other telecommunications operators, we may be unable to provide services at competitive prices and therefore lose market share and revenues."

        Of the telecommunication services we provide, broadband Internet access is among the most competitive. While the Moscow and St. Petersburg markets have become mature in recent years, regional markets are the fastest growing markets, and it is expected that regional markets will follow the same trend as the Moscow and St. Petersburg markets in the coming years, with competition in such markets becoming extremely intense. If we fail to obtain and maintain a substantial share of the broadband Internet access market, our business, financial condition, results of operations or prospects or the value of the ADSs may be materially adversely affected.

        In addition, we believe that Rostelecom, as a state-controlled company, is currently able to influence telecommunications policy and regulation in Russia and may cause substantial increases in interconnect rates for access to fixed line operators' networks by mobile cellular operators. Similarly, Rostelecom may cause substantial decreases in interconnect rates for access to mobile cellular operators' networks by fixed line operators, which could cause our revenues to decrease and may materially adversely affect our business, financial condition and results of operations.

Competition in the foreign markets of our operation

        Competition in the Ukrainian wireless telecommunications market has significantly intensified over the last several years and may further intensify as a result of the current political crisis. See "—Political and Social Risks—Political instability in Ukraine could have a material adverse effect on our operations

in Ukraine and on our business, financial condition and results of operations," and "—A deterioration in relations between Russia and other former Soviet republics and/or the United States and the European Union could materially adversely affect our business, financial condition, results of operations and prospects and the value of our shares and ADSs."

        In October 2010, the Antimonopoly Committee of Ukraine (the "AMC"), approved the merger of Kyivstar, our primary mobile competitor in Ukraine, with URS and Golden Telecom Ukraine, a Ukrainian mobile operator controlled by VimpelCom, in connection with VimpelCom's restructuring. On September 4, 2013, Golden Telecom ceased to provide mobile telecommunication services in Ukraine, and its subscribers were invited to re-connect to Kyivstar. Aggressive pricing by our competitors in Ukraine, driven primarily by Astelit, has driven down the price per minute levels in recent years for mobile communication, which in conjunction with the economic crisis in Ukraine has contributed to the slowdown in the growth rate of the Ukrainian wireless telecommunications market. Presently, the controlled rise of prices, monetization of services, the customer experience of our services and value for money are the most important drivers for the competitive situation in Ukraine. The economic part of the Association Agreement with the European Union signed by Ukraine on June 27, 2014, may adversely affect our own business, financial condition and results of operations due to a possible increase in competition. The implementation of the Association Agreement requires harmonization of Ukrainian legislation and adoption of certain EU regulations on telecommunications services. In this regards, no assurance can be given as to the exact nature of the intended changes, their potential implementation and possible impact on our business.

        The competitive situation for our services in Ukraine is influenced by the launch of 3G/UMTS services, as well as by the prolongation of the Contract on strategic partnership with Vodafone signed on October 15, 2015. Through cooperation with Vodafone, MTS Ukraine started operating in Ukraine under the Vodafone brand. The competitive situation may be also influenced by the introduction of a mobile number portability ("MNP") service (however the terms of MNP implementation are still unknown). Provisions regarding MNP are already in force in Russia, see also "—Legal Risks and Uncertainties—Regulatory changes in Russia, including the reduction of settlement rate, regulation of other inter-carrier and subscriber tariffs, the mobile number portability principle and others, as well as regulatory changes at the international level may have a material adverse effect on our financial condition and results of operations."

        In Belarus, our associate MTS Belarus faces increasing competition and aggressive pricing from Best CJSC, a subsidiary of System Capital Management and Turkcell Iletisim Hizmetleri A.S. ("Turkcell") operating in Belarus under the "life:)" brand. Additionally, in 2011, the government of Belarus announced its intention to hold a public tender to privatize a 51% ownership interest in MTS Belarus with an opening price of approximately RUB 29.4 billion. The public tender was scheduled to be held on December 23, 2011, but was cancelled due to a lack of bidders. The latest attempt to find an investor for the 51% state-owned stake in MTS Belarus took place in February 2014. However, it did not proceed due to the same reason, lack of bidders. A date for the next tender has not yet been specified. The terms of share disposal have not yet been determined, although it may be conducted either through a public tender or by entering into a direct contract with a particular purchaser. If we are unable to acquire this ownership interest at a commercially reasonable price, or if it is acquired by one of our competitors, it may impact our competitive position and results of operations in Belarus.

        We also face competition in Armenia. In 2009, France Telecom operating under the Orange brand entered the Armenian telecommunications market and began offering voice and data transmission services, as well as mobile phones at highly competitive prices. On July 22, 2015, Orange announced leaving the Armenian market and 100% of Orange Armenia shares were sold to Armenian internet service provider, Ucom. The transaction was approved by the Public Services Regulatory Commission of the Republic of Armenia on August 20, 2015 and 12 months after entering into transaction Ucom will continue rendering voice and internet services under the Orange Armenia brand.

        Following the resumption of our operations in Turkmenistan we continue to face price competition from our main competitor Altyn Asyr on international roaming rates and also capacity restrictions that impact on the development of our third-generation "3G" mobile data network in Turkmenistan. MTS-Turkmenistan is required to route both international traffic signals as well as domestic traffic signals entirely through the telecommunications network infrastructure of the state owned telecom operator Turkmentelekom. However, in spite of our further requests for additional network capacity in accordance with our interconnection agreements with Turkmentelekom, there has not been a corresponding increase in capacity made available to us to accommodate the volume of MTS-Turkmenistan's traffic signals. In addition, Turkmentelekom may also refuse to lease communication lines needed for the day-to-day operation of MTS-Turkmenistan's 3G network. As a result, the data service of MTS-Turkmenistan could become less attractive for the subscribers, which could adversely affect the results of our operations in Turkmenistan.

We are subject to anti-corruption laws in the jurisdictions in which we operate, including anti-corruption laws of Russia and the US Foreign Corrupt Practices Act (the "FCPA"), and we may be subject to the UK Bribery Act of 2010 (the "UK Bribery Act"). Our failure to comply therewith could result in penalties which could harm our reputation and have a material adverse effect on our business, financial condition and results of operations.

        We are subject to the FCPA, which generally prohibits companies and their intermediaries from making improper payments to foreign officials for the purpose of obtaining or keeping business and/or other benefits, along with various other anti-corruption laws. We may also be subject to the UK Bribery Act. The UK Bribery Act is broader in scope than the FCPA in that it directly addresses commercial bribery in addition to bribery of public officials and it does not recognize certain exceptions, notably facilitation payments that are permitted by the FCPA.

        We operate primarily in Russia and other countries of the former Soviet Union, many of which pose elevated risks of corruption violations. We and certain of our subsidiaries are in frequent contact with persons who may be considered "foreign public officials" under the FCPA and UK Bribery Act, and therefore, are subject to an increased risk of potential FCPA and UK Bribery Act violations. If we are not in compliance with the FCPA, the UK Bribery Act and other laws governing the conduct of business with government entities (including local laws), we may be subject to criminal and civil penalties and other remedial measures, which could have an adverse impact on our business, results of operations, financial condition and liquidity.

        As disclosed in our public filings, in March 2014, we received requests for the provision of information from the United States Securities and Exchange Commission and the United States Department of Justice relating to an investigation of the Group's former subsidiary in Uzbekistan. See also Note 29 to our audited consolidated financial statements. MTS is cooperating with those agencies and has provided and is continuing to provide information in response to their requests. We cannot predict the outcome of the investigations, including any fines or penalties that may be imposed, and such fines or penalties could be significant. Any investigation of any potential violations of the FCPA, the UK Bribery Act or other anti-corruption laws by the US, the UK or foreign authorities could have an adverse impact on our business, financial condition and results of operations.

Our controlling shareholder has the ability to take actions that may conflict with the interests of other holders of our securities.

        We are controlled by Sistema, which owns 51.46% of our total charter capital (53.46% excluding treasury shares). If not otherwise required by Russian law and/or our charter, resolutions at a shareholders' meeting are adopted by a simple majority in a meeting at which shareholders holding more than half of the issued share capital are present or represented. Accordingly, Sistema has the power to control the outcome of most matters to be decided by vote at a shareholders' meeting and, as

10

Table of Contents

long as it holds, either directly or indirectly, a majority of our shares, Sistema will control the appointment of a majority of directors and removal of all directors. Sistema is also able to control or significantly influence the outcome of any vote on matters which require three-quarters majority vote of a shareholders' meeting, such as amendments to the charter, proposed reorganizations, substantial asset sales, and other major corporate transactions, among other things. Thus, Sistema can take actions that may conflict with the interests of other security holders. In addition, under certain circumstances, a disposition by Sistema of its controlling stake in our company could harm our business. See also "—Risks Relating to Our Financial Condition—If a change in control occurs, our noteholders and other debt holders may require us to redeem notes or other debt, which could have a material adverse effect on our financial condition and results of operations."

        Sistema has a significant amount of outstanding debt. As of December 31, 2015, Sistema had consolidated indebtedness of approximately RUB 14,643 million of short-term debt, RUB 128,014 million comprising the short-term portion of its long-term debt, and RUB 414,103 million of long-term debt (net of the short-term portion). At the corporate level, Sistema had approximately RUB 191 million of short-term debt, RUB 25,769 million comprising the short-term portion of its long-term debt, and RUB 90,846 million of long-term debt (net of the short-term portion). Therefore, Sistema will require significant funds to meet its obligations, which may come in part from dividends paid by its subsidiaries, including us.

        Our shareholders approved semi-annual dividends for 2014 in the amount of RUB 12,812 million. In 2015, our shareholders approved annual dividends for 2014 in the amount of RUB 40,418.86 million and semi-annual dividends for 2015 in the amount of RUB 11,592.58 million.

        Annual dividends are calculated at the exchange rate on the date when dividends are declared at the General Meeting of Shareholders. The indentures relating to our outstanding notes and other debt do not restrict our ability to pay dividends. As a result of paying dividends, our reliance on external sources of financing may increase, our credit rating may decrease, and our cash flow and ability to repay our debt obligations, or make capital expenditures, investments and acquisitions could be materially adversely affected. Furthermore, our credit ratings can be and have been affected in the past by Sistema's activity and credit ratings.

Failure to effectively implement our geographic expansion strategy as well as difficulties with operational management of the acquired businesses could hamper our continued growth and profitability.

        Our continued growth depends, in part, on our ability to identify attractive opportunities in markets that will grow and on our ability to manage the operations of acquired or newly established businesses. Our acquisitions may occur in countries that represent new operating environments for us and, in many instances, may be located a great distance from our corporate headquarters in Russia. We therefore may have less control over their activities. We may also face uncertainties with respect to the operational and financial needs of these businesses, and may, in the course of our acquisitions, incur additional debt to finance the acquisitions and/or take on substantial existing debt of the acquired companies. In addition, we anticipate that the countries into which we may expand will be emerging markets and, as with countries of our current presence, subject to greater political, economic, social and legal risks than more developed markets.

        For example, see "—Legal Risks and Uncertainties—The inability of MTS-Turkmenistan to sustain its operations in Turkmenistan on commercially acceptable terms or at all may adversely affect our business, financial condition and results of operations," and "—The inability of our subsidiaries in the countries in which we are present to maintain control over their operations and assets may adversely affect our business, financial condition and results of operations." Our failure to identify attractive opportunities for expansion into new markets and to manage the operations of acquired or newly

established businesses in these markets could hamper our continued growth and profitability, and have a material adverse effect on our financial condition, results of operations and prospects.

Acquisitions and mergers may pose significant risks to our business.

        We have expanded our business through a number of acquisitions. We will continue to evaluate opportunities to acquire, invest in or merge with other existing operators or license holders in the CIS and in growing markets outside the CIS, as well as other complementary businesses.

        Prior to 2009, most of our acquisitions were of regional operators with a focus on expanding our network and subscriber footprint. Following acquisition of a majority stake in Comstar in 2009, we expanded into the fixed line communications market. Upon completion of the transaction with Comstar in 2011, we also obtained full control over MGTS, a PSTN operator in Moscow. In 2010, we acquired Sistema Telecom in order to obtain full control over our logos. In 2011 and 2012, our acquisitions focus shifted to acquiring a minority stake in a subsidiary company of Multiregion JSC and other regional cable TV and broadband providers in furtherance of our strategy to become a provider of integrated telecommunications services. In 2014 and 2015, our acquisition focus also covered regional mobile operators, as well as one of the largest system integrators and complex IT solutions providers in Russia, NVision Group JSC ("Nvision Group").

        These and other business combinations entail a number of risks that could materially and adversely affect our business, financial condition, results of operations and prospects, including the following:

•

incorrect assessment of the value of any acquired target;



•

assumption of the acquired target's liabilities and contingencies;



•

failure to realize any of the anticipated benefits or synergies from any acquisitions or investments we complete;



•

problems integrating the acquired businesses, technologies or products into our operations;



•

incurrence of debt to finance acquisitions and higher debt service costs related thereto;



•

difficulties in retaining business relationships with suppliers and customers of the acquired company;



•

risks associated with businesses and markets in which we lack experience, including political, economic, social, legal and regulatory risks and uncertainties;



•

competition risks;



•

more onerous government regulation;



•

potential loss of key assets of the acquired company;



•

potential loss of key employees of the acquired company;



•

potential write-offs of acquired assets; and



•

lawsuits arising out of disputes over ownership of acquired assets and/or the enforcement of indemnities relating to the title to such assets.

        For example, in 2014, an impairment charge related to equity investment in MTS Bank was recognized in the non-operating share of the loss of the associates in the accompanying consolidated statement of profit or loss. See Note 8 to our audited consolidated financial statements. For other examples, including impairment of goodwill in Armenia, see Note 14 to our audited consolidated financial statements.

        In addition, companies that we acquire may not have internal policies, including accounting policies and internal control procedures that are compatible, compliant or easily integrated with ours.

        If any of our future business combinations is structured as a merger with another company, or we merge with or absorb a company subsequent to its acquisition by us, such a merger would be considered a corporate reorganization under Russian law. In turn, this would provide our creditors with a statutory-based right to file a claim seeking to accelerate their claims or terminate the respective obligations, as well as seek damages. To prevail, the creditors would need to prove in court that we will not perform our obligations in due course and the amount of damages suffered. Secured creditors would be required to further prove that the security provided by us, our shareholders or third parties is not sufficient to secure our obligations. Creditors whose claims are secured by pledges do not have the right to claim additional security.

        In April 2013, we acquired a 25.095% stake in MTS Bank. In 2013, we also signed a profit-sharing agreement whereby we and MTS Bank would realize 70% and 30% of the proceeds from the MTS Dengi (MTS Money) project respectively. The MTS Dengi project launched by us and MTS Bank is aimed at providing customers throughout Russia with payment tools, including credit cards, near-field communications-enabled SIM cards and PoS (point-of-sale) credit. If the risks associated with participating in the banking sector lead to our inability to receive the expected profits from MTS Dengi project it could have an adverse effect on our financial statements and results of operations. Within the last quarter of 2014, the Group increased its interest in MTS Bank to 27.0% through participation in an additional share issue of MTS Bank, and paid RUB 3,639 million for shares acquired. As a participant of the state recapitalization program, in the end of 2015 MTS Bank received federal loan bonds for total value of RUB 7.25 billion from the Deposit Insurance Agency. In 2016, Sistema and MTS participated in the additional share issuance of MTS bank in proportion to our current direct ownership stakes. MTS signed a binding agreement with MTS Bank, through which we acquired 946,347 ordinary shares of the MTS Bank's additional shares issuance for RUB 1.3 billion. As a result of the transaction, Group's ownership stake in MTS Bank decreased from 27.0% to 26.8%. See Note 30 to our audited consolidated financial statements.

        In April 2014, we acquired a 10.82% stake in OZON Holdings Limited ("OZON"), the Russian e-commerce company, through an additional share issuance for RUB 2,702 million. The acquisition is aimed to provide exclusive access to OZON's sales channels for MTS's products and services as well as to further enhance our online presence. If we are not successful in expanding our distribution network and developing more effective customer touch points and services, this may have an adverse impact on our business, financial condition and results of operations.

        In May and December 2014, we acquired from third-party investors 35.59% and 3.52% stakes, respectively, in Teleservice OJSC ("Teleservice"), a broadband and Pay-TV provider in Voronezh. Upon completion of the transactions, MTS Group's stake in Teleservice increased to 93.4%.

        In the fourth quarter of 2014, our subsidiary LLC "Telecom Povolzhye" acquired three regional assets of Smarts Group aiming to strengthen leadership in Bashkortostan market as well as to expand our operations in Penza and Ivanovo regions. LLC "Telecom Povolzhye" (as buyer), MTS (as guarantor for payment) entered into a sale and purchase agreement with Bolaro Holdings Limited (as seller 1), SMARTS OJSC (as seller 2) and Kiryushin Gennady Vasiljevich ("KGV", as guarantor) relating to the entire issued share capital of three telecom operators Penza-GSM, SMARTS-Ivanovo and SMARTS-Ufa ("Companies 1-3") and four new telecom operators to be established as a result of a spin-out from SMARTS OJSC ("Companies 4-7") ("Agreement"). The sale and purchase of Companies

Table of Contents

1-3 was completed at signing however, sellers failed to complete the transaction in respect of the Companies 4-7 as was provided in the Agreement and completion did not take place. In December 2015, MTS filed a request for arbitration in LCIA seeking specific performance by sellers and KGV to sell the Companies 4-7 or to pay damages in the amount equal to $35 million (RUB 2,551 million as of December 31, 2015). In support of the request MTS sought an injunction upheld by the Higher Court of Justice Queen`s Bench Division Commercial Court prohibiting sellers and KGV to dispose of, sell, or diminish the value of the companies' shares. In January 2016, Arbitrazh Court of Samara region granted injunction arresting the shares and prohibiting certain third parties to conduct any transactions related to the shares in share register.

        On January 22, 2015, our subsidiary MGTS closed deals on sale of 49.95% stake in Joint Stock Company "Intellect Telecom" and acquisition of the controlling stake in Public Joint Stock Company "Navigation-information systems" comprising of 89.536% of the charter capital. In 2015, we acquired 100% of the shares of NVision Group, one of the largest system integrators and complex IT solutions providers in Russia. On one hand, the acquisitions will allow us to obtain control over our billing system, reduce our billing and IT related expenses, develop our proprietary technological platform for machine-to-machine (M2M) solutions and enhance our presence in the areas of telematics solutions for transport, insurance and security systems, on the other hand, additional risks relating to the acquired companies' liabilities might arise. See also Note 5 to our audited consolidated financial statements.

        We may also be involved in various litigation to protect our title or other rights related to acquired businesses and incur some unpredicted loss. For example, in December 2005, we acquired a 51% stake in Tarino Limited from Nomihold Securities Inc. for approximately RUB 4,322 million in cash and entered into a put and call option agreement for the remaining 49% interest for a price of approximately RUB 4,898 million as we believed, that at that time it was the indirect owner of Bitel, a Kyrgyz company holding GSM 900/1800 license for the entire territory of Kyrgyzstan. In the same year, following a decision of the Kyrgyz Supreme Court, Bitel's offices were seized by a third party and we lost operational control over Bitel. In 2007, Nomihold Securities Inc. exercised the put option for the remaining stake in Bitel. During 2005-2013 we wrote down more than RUB 8,798 million relating to the loss of Bitel and other litigation with Nomihold Securities Inc. During the same period we also had other litigation in various jurisdictions to defend our rights relating to Bitel and its assets. In June 2013, an agreement was reached between Nomihold and other associated parties to settle all the claims arising in relation to Bitel and its assets, pursuant to which all proceedings between all the parties involved in such litigation were discontinued and waived and we received a total payment in cash in the amount of approximately RUB 4,909 million. The settlement also fully discharged all our outstanding obligations to Nomihold Securities Inc. As a result of the settlement, we released a provision relating to the exercise the put option for acquisition of the remaining stake in Bitel plus damages, interest and other cost that have been provided for in relation to the dispute with Nomihold.

        In addition, a merger, as well as any corporate reorganization and any business combination that constitutes a "major transaction" under Russian law, would trigger the right of our shareholders who abstain from voting on or vote against such reorganization or transaction to sell, and our obligation to buy, their shares in an amount representing up to 10% of our net assets as calculated under Russian Accounting Standards. See "—Legal Risks and Uncertainties—Shareholder rights provisions under Russian law could impose additional obligations and costs on us, which could have a material adverse effect on our business, financial condition, results of operations and prospects."

If our purchase of Ukrainian Mobile Communications ("UMC") is found to have violated Ukrainian law or the purchase is unwound, our business, financial condition, results of operations and prospects would be materially adversely affected.

        On June 7, 2004, the General Prosecutor of Ukraine filed a claim against us and others in the Kiev Commercial Court seeking to unwind the sale made to us by Joint Stock Company Ukrtelecom

14

Table of Contents

("Ukrtelecom") of its 51% stake in UMC. The complaint also sought an order prohibiting us from disposing of our 51% stake in UMC until the claim was resolved on the merits. The claim was based on a provision of the Ukrainian privatization law that included Ukrtelecom among a list of "strategic" state holdings prohibited from alienating or encumbering its assets during the course of its privatization. Although the Cabinet of Ministers of Ukraine had issued a decree in May 2001 specifically authorizing the sale by Ukrtelecom of its entire stake in UMC, the General Prosecutor asserted that the decree contradicted the privatization law and that the sale by Ukrtelecom was therefore illegal and should be unwound. On August 12, 2004, the Kiev Commercial Court rejected the General Prosecutor's claim.

        On August 26, 2004, the General Prosecutor's Office requested the Constitutional Court of Ukraine to review whether certain provisions of the Ukrainian privatization law limiting the alienation of assets by privatized companies were applicable to the sale by Ukrtelecom of UMC shares to us. On January 13, 2005, the Constitutional Court of Ukraine refused to initiate the constitutional proceedings arising from the request of the General Prosecutor's Office on the grounds that the request was incompatible with the requirements of Ukrainian constitutional law, and that the issue as it was raised in the request, did not fall within the jurisdiction of the Constitutional Court of Ukraine. The Constitutional Court of Ukraine's decision does not prevent other persons having the right to apply to the Constitutional Court of Ukraine from challenging the constitutionality of provisions of the Ukrainian privatization law applicable to the sale by Ukrtelecom of the UMC shares, and also does not preclude the future challenge of such sale in the commercial courts of Ukraine.

        If the Constitutional Court of Ukraine rules that the provisions of the Ukrainian privatization legislation applicable to Ukrtelecom's sale of its stake in UMC are unconstitutional, the Kiev Commercial Court could be requested to re-open the case based on new circumstances and could potentially include additional persons that were not parties to the original proceeding and/or admit additional claims.

        In addition, as UMC was formed at a time when Ukraine's legislative framework was developing in an uncertain legal environment, its formation and capital structure may also be subject to challenges. In the event that our purchase of UMC is found to have violated Ukrainian law or the purchase is subject to repeated challenge, or unwound, in whole or in part, our business, financial condition, results of operations and prospects would be materially adversely affected.

If we cannot successfully develop our network, we will be unable to expand our subscriber base and maintain our profitability.

        Our ability to increase our subscriber base depends upon the success of our network expansion. We have expended considerable amounts of resources to enable both organic expansion and expansion through acquisitions and plan to continue to do so. Limited information regarding the markets into which we have or are considering expanding, either through acquisitions or new licenses, complicates accurate forecasts of future revenues from those regions, increasing the risk that we may overestimate these revenues. In addition, we may not be able to integrate previous or future acquisitions successfully or operate them profitably. Any difficulties encountered in the transition and integration process and in the operation of acquired companies could have a material adverse effect on our results of operations.

        The build-out of our network is also subject to risks and uncertainties, which could delay the introduction of services in some areas and increase the cost of network construction, including difficulty in obtaining base station sites on commercially attractive terms. In addition, telecommunications equipment used in Russia, Ukraine and other CIS countries is subject to governmental certification, and periodic renewals of the same. We are also required to receive permits for the operation of telecommunications equipment as well as governmental certification and/or permission for the import and export of certain network equipment, which can result in procurement delays and slow network

development. The failure of any equipment we use to receive timely certification or re-certification could hinder our expansion plans.

        For example, the import and export of products containing cryptographic hardware is subject to special documentation requirements and approvals. As telecommunication networks comprise various components with cryptographic hardware, we must comply with these requirements in order to import such components. Moreover, where imported equipment does not contain cryptographic hardware, the federal customs service requires manufacturers to provide written confirmation regarding the absence of such hardware. The range of goods requiring the provision of "certificates of conformance" by suppliers and manufactures prior to their import into Russia has also been expanded to cover most of our key network components, and imported radioelectronic equipment is required to be licensed by the Russian Ministry of Industry and Trade. Similar requirements regarding the import and export of cryptographic hardware exist in Ukraine.

        Furthermore, as a result of the downturn in the global financial markets, certain banks have curtailed their lending programs, which may limit our ability to obtain external financing and, in turn, result in the reduction of our capital expenditure program. To the extent we fail to expand our network on a timely basis, we could experience difficulty in expanding our subscriber base. See also "—Risks Relating to Our Financial Condition—If we are unable to obtain adequate capital, we may have to limit our operations substantially, which could have a material adverse effect on our business, financial condition, results of operations and prospects."

Our inability to develop additional sources of revenue could have a material adverse effect on our business, financial condition, results of operations and prospects.

        Mobile penetration in Russia and Ukraine reached 173.6% and 130.4%, respectively, as of September 30, 2015, according to AC&M-Consulting. Until recently, customer growth has been the principal source of revenue growth. Currently, however, increasing competition, market saturation and technological development lead to the increased importance of data services in the Russian market and, to a lesser extent, the markets of other CIS countries. As a result, data services became the key driver of our revenue growth and, therefore, we will need to continue to develop new competitive services, including value-added, 3G, LTE, and others, as well as consider vertical integration opportunities through the development or acquisition of dealers in order to provide us with sources of revenue in addition to standard voice services. Our inability to develop additional sources of revenue could have a material adverse effect on our business, financial condition, results of operations and prospects.

Our failure to further develop and sustain our distribution network as well as the reduction, consolidation or acquisition of independent dealers may lead to a decrease in our subscriber growth rate, market share and revenues.

        Following the restructuring of Euroset Group, the largest mobile handset retailer and leading dealer for major mobile network operators in Russia, as a result of which MegaFon and VimpelCom acquired equal shares of 50%, we were working on development of our proprietary distribution network, signed an additional agreement with Svyaznoy and were working to increase our relationship with small regional dealers. In November 2014, Svyaznoy experienced changes in its ownership structure. In summer 2015, MTS announced termination of payments admission and contract sales via Svyaznoy. On September 29, 2015, Svyaznoy Logistika JSC filed a suit against us and our subsidiary Sibintertelecom JSC for not having paid agent commissions related to the previously sold contracts. The settlement agreement among Svyaznoy Logistika JSC, MTS and Sibintertelecom was approved by the Moscow Arbitrazh Court on February 11, 2016, which resulted in termination of the lawsuit. On December 23, 2015, Trellas Enterprise Limited LLC filed a suit against us claiming compensation in amount of RUB 77,653.8 million for the use of Svyaznoy trademark. The lawsuit was terminated on February 11, 2016, due to the plaintiff's refusal from the claim.

        Currently we are enhancing our retail sales network and developing distribution channels through cooperation with national, regional and local dealers. If we are not successful in expanding and sustaining our proprietary network and maintaining and further developing our distribution network of national, regional and local retailers, our subscriber growth rate, market share and revenues may decrease, which would have an adverse effect on our business, financial condition, results of operations and prospects. See "Item 4. Information on Our Company—B. Business Overview—Mobile Operations—Sales and Marketing—Sales and Distribution."

Governmental regulation of SMP operators in Ukraine could adversely affect our results of operations.

        The interconnect fees charged by us and our competitors for terminating calls connecting to any of our respective networks are subject to regulation by the National Commission for the Regulation on Communications (the "NCRC"), which since November 23, 2011 has been succeeded by the National Commission for the State Regulation of Communications and Informatization (the "NCCIR"). See "Item 4. Information on Our Company—B. Business Overview—Regulation of Telecommunications in the Russian Federation and Ukraine—Regulation in Ukraine—Interconnect" for additional information.

        Following the introduction of "significant market power" (SMP) term to the Telecommunications Law in 2011, in June 2012, the definition of SMP was changed by an amendment to the Telecommunications Law which came into effect on January 8, 2013. From this date qualification as a SMP has been assessed with reference to the market as defined by NCCIR (and not only by reference to the traffic termination market). As previously, criteria i.e. the SMP market share remained the same as in previous version of the Telecommunications Law an operator qualifies as a SMP in a particular market if its share of gross revenue from the provision of traffic transfer services on fixed or mobile telecommunications networks during the last 12 months exceeded 25% of total gross revenues of all telecommunications operators for the same services during the same period.

        On September 22, 2011, the NCRC proposed a draft law on regulating SMP operators which called for, among other things, non-discriminatory access to their infrastructure for the wholesale market and for regulating the retail market. Under the proposed law, the NCRC may place an obligation on SMP operators to separate the accounting of revenues and costs for different services, to calculate the cost of their services according to NCRC rules and to price the services in accordance with NCRC's rules. The draft law "On Electronic Communications" (proposed by NCCIR) that includes provisions mentioned above, was registered by the Verkhovna Rada of Ukraine in December 2015. The draft law is awaiting consideration.

        See also "—Legal Risks and Uncertainties—Changes in Ukrainian telecommunications legislation have caused uncertainty in relation to the regulation of the Ukrainian telecommunications industry and may adversely affect our business, financial condition and results of operations."

If we cannot interconnect cost-effectively with other telecommunications operators, we may be unable to provide services at competitive prices and therefore lose market share and revenues.

        Our ability to provide commercially viable services depends on our ability to continue to interconnect cost-effectively with zonal, intercity and international fixed line and mobile operators in Russia, Ukraine and other countries in which we operate. Fees for interconnecting are established by agreements with network operators and vary depending on the network used, the nature of the call and the call destination.

        At the end of 2014, NCCIR (by its Resolution No. 845 dated December 23, 2014) approved a plan on preparation of regulatory Acts projects being adopted without taking into consideration the requirements of the law "On Principles of State Regulatory Policy in the Area of Economic Activity" for 2015-2016. According to the document mentioned above, NCCIR planned to substantially lower

17

Table of Contents

interconnect rates for the termination of traffic on the network of SMP operators. By the resolution dated August 4, 2015 "On introduction of traffic transmission rates over the network of telecommunication operators with significant competitive advantage on traffic transmission services market," NCCIR approved new rates valid since October 1, 2015. As a result, interconnect rates both for termination of national traffic on fixed line telecommunication networks and termination of traffic on mobile networks have been lowered, the rates for termination of traffic on local networks remained unchanged. In addition, it is planned to reduce the rates for termination of traffic both on mobile and fixed line networks starting from July 1, 2016, according to the decision of NCCIR dated January 26, 2016. This planned reduction of interconnect rates for termination of traffic on the networks of SMP operators may adversely affect MTS Ukraine revenues.

        Although Russian legislation requires that operators of public switched telephone networks that are deemed to be "substantial position" operators cannot refuse to provide interconnects or discriminate against one operator over another, we believe that in practice, some operators attempt to impede wireless operators by delaying interconnect applications and establishing technical conditions for interconnecting that can be met only by certain operators.

        Any difficulties or delays in interconnecting cost-effectively with other networks could hinder our ability to provide services at competitive prices or at all, causing us to lose market share and revenues, which would have a material adverse effect on our business and results of operations. See also "—If we or any of our mobile operator subsidiaries operating in Russia are identified as an operator occupying a "substantial position," the regulator may reduce our interconnect tariffs which, in turn, may have a material adverse effect on our financial condition and results of operations."

        In addition, as part of the restructuring of Svyazinvest, the fourth national mobile operator in Russia was established on the basis of "Tele2 Russia" and mobile assets of Rostelecom. As Svyazinvest controlled regional fixed line operators in all regions of Russia (other than Moscow), a mobile operator established as part of the Svyazinvest group may receive preferential terms for interconnecting with these operators, which would allow it greater flexibility in setting tariffs and put us at a competitive disadvantage. It is currently unclear how the establishment of the fourth federal mobile operator may influence our interconnect agreements and our expenses. See also "—We face increasing competition in the markets where we operate, which may result in reduced operating margins and loss of market share, as well as different pricing, service or marketing policies."

We may not realize the benefits we expect to receive from our investments in 3G and 4G wireless services, which could have a material adverse effect on our business and results of operations.

        In May 2007, the Federal Service for Supervision in the Area of Communications and Mass Media awarded MegaFon, VimpelCom and us a license to provide 3G services in the Russian Federation. In July 2012 these three companies and Rostelecom were awarded licenses to provide 4G services. Following the integration of Rostelecom's mobile assets and Tele2 Russia in 2014, Tele2 Russia got control over licenses to provide 3G and 4G services. The 3G license allows us to provide mobile radio telephone services using the International Mobile Telecommunications-2000 ("IMT-2000/UMTS") standard. The 4G license allows us to provide services using the LTE standard. 4G wireless services are expected to provide faster, higher quality data transfer and streaming capabilities as compared to 2G and 3G and may pose additional competition for 3G providers. Historically, mobile operators that have developed 3G and 4G networks have experienced various difficulties and challenges, including a limited supply of compatible handsets, limited international roaming capabilities, as well as 3G and 4G software and network-related problems. We may experience similar problems or encounter new

18

Table of Contents

difficulties when developing our 3G and 4G networks and may be unable to fully resolve them. For example, we cannot be certain that:

•

we will be able to build-out our 4G network in a timely manner or within the time frame stipulated by the license terms;



•

our 3G and 4G network and services will deliver the quality and level of service that our customers demand or prefer;



•

we will be able to provide all contemplated 3G and 4G services at reasonable prices and within a reasonable timeframe;



•

manufacturers and content providers will develop and offer new marketable products and services for our 3G and 4G network on a timely basis;



•

there will be sufficient demand for 3G and 4G services in the markets where we operate;



•

our 3G and 4G network will be commercially viable in all of the locations we are required to operate pursuant to our 3G and 4G licenses;



•

our competitors will not offer similar services at lower prices; and



•

changes in governmental policies, rules, regulations or practices will not affect our network rollout or our business operations.

        See also "—If we cannot successfully develop our network, we will be unable to expand our subscriber base and maintain our profitability."

        In addition, Russian military authorities also use frequencies in the 3G and 4G spectrum, which may limit the availability of 3G and 4G frequencies for commercial use in certain areas. During the construction of our 3G and 4G network, there is also a risk that the frequencies assigned to us for commercial use may overlap with frequencies used by the Russian military. For example, conflicts over the availability of frequency reserved for military use in Moscow caused delay in the commercial launch of 3G services in Moscow by all 3G license holders, although some of these frequencies were cleared for commercial use in 2009. If additional overlap were to occur, it could cause problems or delays in the development and operation of our 3G and 4G network in Russia.

        We may also face competition from operators using second generation ("2G") or other forms of 3G technology. For example, licenses for the use of CDMA technology have already been granted for the provision of wireless services in a number of regions throughout Russia. CDMA is a 2G digital cellular telephony technology that can be used for the provision of both wireless and fixed services. If CDMA operators were able to develop widespread networks throughout Russia, we would face increased competition.

        Potential competition from other 3G, CDMA and 4G providers, together with any substantial problem with the rollout of our 3G and 4G network and provision of 3G and 4G services in the future, could materially adversely affect our business, financial condition and results of operations.

        In December 2013 and in July 2014, the State Commission for Radio frequencies introduced several modifications to the conditions of using the frequency band for mobile radio communication networks. These changes resulted in implementation of the principle of technological neutrality for frequency bands 900 MHz (UMTS and LTE) and 1800 MHz (LTE), and also included the imposition of certain additional obligations on network operators. Pursuant to these modifications, in the event that we receive new bandwidth allocation, and also as a result of the renewal of the current decisions of the State Commission for Radio Frequencies or in case of using frequencies on the terms of technological neutrality principle, we are obliged to provide network coverage to settlements with lower subscriber numbers, where the commercial rationale for doing so may otherwise be limited. Such

changes lead to additional costs for the construction of our 3G and 4G wireless network and consequently may adversely affect our business, financial condition and results of operations.

If we are unable to successfully develop and/or deploy 4G wireless services in the countries in which we operate or one of the operators in the market obtains significant technological and/or commercial advantage over us in 4G wireless services, it may have a material adverse effect on our business and results of operations in the long term.

        The next step in the development of telecommunications in the countries where we operate is the deployment of 4G/LTE networks. The cost of 4G/LTE network development and quality of services (data speed, quality of coverage) depends on the band and the width of frequency range given to an operator.

        In September 2011, the Russian government announced its intention to auction frequencies for LTE use on a national level in 2012. Additionally, outside of the auction process, the State Radio Frequencies Commission granted Scartel (operating the Yota retail brand) a paired range of LTE frequencies (2x30 MHz), in the 2.5-2.7 GHz band for use on the whole territory of Russia in exchange for 4G frequencies held by Scartel for Wi-Max technology with a total width of 70MHz. Four sets of frequencies in the 791-862 MHz band were planned to be sold during the auction in 2012, after which the winners of the frequencies would receive frequencies in the 2.5-2.7 GHz band. The remaining frequencies 40 MHz of the 2.5-2.7 GHz band were allocated evenly during the tender among four major market participants (us, VimpelCom, MegaFon and Rostelecom).

        Initially it was planned that all operators would receive equal access to the Scartel infrastructure, which would allow each operator to reduce its 4G/LTE network development costs. In March 2011, MTS, MegaFon, VimpelCom and Rostelecom signed a non-binding memorandum of understanding with Scartel, according to which MTS, MegaFon, VimpelCom and Rostelecom were to receive access to Scartel's 4G network infrastructure (which was yet to be built) and were to receive options to purchase shares in Scartel in 2014 at a price determined by an independent appraisal. MTS considered a preliminary value assessment of Scartel to be unduly high.

        In July 2012, Alisher Usmanov and Scartel shareholders (Telconet Capital and Rostechnologyi) formed a telecommunications holding company, Garsdale. In exchange for an 82% interest in Garsdale, AF Telecom, which is controlled by Alisher Usmanov, contributed 50% of MegaFon's shares into Garsdale's share capital. Rostechnologyi and Telconet Capital, which held 25.1% and 74.9% stakes in Scartel, respectively, contributed 100% of Scartel into Garsdale's share capital, in return for which they received an 18% stake in Garsdale, which was split equally between Rostechnologyi and Telconet Capital. On 12 July 2012, the Federal Service for Supervision of Communications, Information Technology and Mass Media ("Roskomnadzor") awarded each of MegaFon, VimpelCom, Rostelecom and us a license to provide 4G services using LTE and its subsequent modifications in the frequency range of 791-862 MHz.

        On October 1, 2013, MegaFon acquired Maxiten Co Limited, which in turn owned 100% of the shares in Scartel and Yota Ltd. from Garsdale. The transaction was approved by the general shareholders meeting of MegaFon and by the Federal Antimonopoly Service ("FAS"). At present, MegaFon holds 4G/LTE network through Scartel as well as controlling the continuous spectrum of frequencies 2 × 40 MHz in the band of LTE FDD 2600 MHz. As a result of this transaction, MegaFon obtained a competitive advantage in terms of LTE network development costs and may also obtain an advantage in LTE network performance. In addition, as a result of the deal, MegaFon consolidated financial and operational indicators of Scartel/Yota which increased its formal market share in the mobile communications market.

        According to the decision of State Commission for Radio Frequencies as of March 16, 2012 Roskomnadzor is not permitted to assign LTE frequencies to any telecommunication operator except

for MegaFon and Rostelecom in the Krasnodarsky Region until the end of 2016. On April 11, 2013, we filed an application with the State Commission for Radio Frequencies to amend this decision and requested a postponement of the introduction of such restrictions until the end of 2014. The consideration of our application was postponed for the duration of the Olympic Games and on April 16, 2014, the State Commission for Radio Frequencies amended its own decision as of March 16, 2012, which made it possible for communication operators to submit applications for LTE frequencies in the Krasnodarsky region. However, expiration date of the decision of the State Commission for Radio Frequencies which previously allocated LTE frequencies to Rostelecom and MegaFon, remained unchanged (until December 31, 2016). At the end of June 2014, MegaFon appealed the decision of the State Commission for Radio Frequencies by filing a lawsuit against the State Commission for Radio Frequencies and the Ministry of Communications. On January 26, 2015, the Moscow Arbitrazh Court upheld MegaFon's claim and invalidated the decision of the State Commission for Radio Frequencies dated April 16, 2014. Later, the Ninth Arbitrazh Court of Appeals rejected the appeal claim of MTS filed against the decision of the first instance that had satisfied MegaFon's claim against the State Commission for Radio Frequencies. After the decision of the Ninth Arbitrazh Court of Appeals MTS filed a cassation petition to the Arbitrazh Court of Moscow area. On October 13, 2015, the acts of the inferior courts were reconfirmed by the Arbitrazh Court of Moscow area. According to those acts, the decision of the State Commission for Radio Frequencies on reduction of moratorium terms for LTE networks launch in the Krasnodarsky region, was declared illegal. In December 2015, we filed a cassation petition to the Supreme Court of the Russian Federation. On February 12, 2016, the petition was dismissed by the Supreme Court. Though relying on the technological neutrality principle we have launched 4G network in the frequency range of 1800 MHz in the Krasnodarsky Region since March 2015, our inability to develop an LTE network in the region using 800 and 2600 MHz bands until the end of 2016 may have an adverse effect on our business, financial condition and results of operations.

        On September 18, 2013, the mobile operator Altyn Asyr, our major competitor in Turkmenistan, brought into operation a 4G network using LTE technology. In July 2015, MTS Turkmenistan was granted a telecommunication license valid until 2018. The license provides for the possibility of rendering 4G services, however, launch and service quality are limited with frequency band and width of the frequency range, which may lead to the loss of revenues from its data service and could have an adverse effect on the results of our operations.

        Furthermore, the limited number of available frequencies may prevent us from realizing the full benefits we expect to receive from the development of a 4G network, because our network capacity would be constrained and our ability to expand limited. Moreover, if we cannot develop a commercially viable 4G network, and one of our competitors does, that competitor would have an advantage over us, which in turn may have a material adverse effect on our business.

Service disruptions on our networks could lead to a loss of subscribers, damage to our reputation, violations of the terms of our licenses and subscriber contracts and penalties.

        We are able to deliver services only to the extent that we can protect our network systems against damage from communications failures, computer viruses, power failures, natural disasters and unauthorized access. Any system failure, accident or security breach that causes interruptions in our operations could impair our ability to provide services to our customers and materially adversely affect our business and results of operations. In addition, to the extent that any disruption or security breach results in a loss of or damage to customers' data or applications, or inappropriate disclosure of confidential information, we may incur liability as a result, including costs to remedy the damage caused by these disruptions or security breaches.

        While we maintain back-up systems for our telecommunications equipment, network management, operations and maintenance systems, these systems may not ensure recovery in the event of a network failure. In particular, in the event of extensive software and/or hardware failures, significant disruptions to our systems could occur, leading to our inability to provide services. The quality of our services in roaming (including roaming between networks) also depends, inter alia, on the network quality of our roaming partners which is out of our control. Disruptions in our provision of services could lead to a loss of subscribers, damage to our reputation, violations of the terms of our licenses and subscriber contracts and penalties.

        Our computer and communications hardware is protected through physical and software safeguards. However, it is still vulnerable to fire, storm, flood, loss of power, telecommunications failures, interconnect failures, physical or software break-ins, viruses and similar events. Although our computer and communications hardware is insured against fires, storms and floods, we do not carry business interruption insurance to protect us in the event of a catastrophe, even though such an event could have a material adverse effect on our business.

Failure to fulfill the terms of our licenses could result in their suspension or termination, which could have a material adverse effect on our business and results of operations.

        Each of our mobile licenses requires service to be offered by a specific date and some contain further requirements as to network capacity and territorial coverage to be reached by specified dates. In addition, all of our mobile licenses require us to comply with various telecommunications regulations relating to the use of radio frequencies and numbering capacity allocated to us, network construction, interconnect rules and technical requirements relating to compliance with law enforcement authorities' requests, among others. The license requirements applicable to our fixed line businesses include participation in a federal communications network, adherence to technical standards, investment in network infrastructure, employment of Russian technical personnel and the provision of certain services to the federal government and PSTN subscribers at regulated tariffs, among others. If we fail to comply with the requirements of Russian, Ukrainian or other applicable legislation or we fail to meet any terms of our licenses, our licenses and other authorizations necessary for our operations may be suspended or terminated which could significantly limit our operations. In addition to the impact on our operations, the suspension or loss of certain licenses could also cause an event of default under certain of our debt obligations and certain of our debt to be accelerated. A suspension or termination of our licenses or other necessary governmental authorizations could therefore have a material adverse effect on our business and results of operations.

        For example, in February 2015, MTS Ukraine won the lot for the use of 1950-1965/2140-2155 MHz frequency bands in a tender allocating 3G licenses. On March 24, 2015, MTS Ukraine paid the entire amount due for the license and received the UMTS license that is valid for a period of 15 years.

        According to the tender terms, all regional centers of Ukraine have to be covered with 3G communication (within the bands granted to the successful bidder) within 18 months from the date of the license issuance, all settlements with a population of over 10,000 have to be covered with 3G communication within the period of 6 years. Successful bidder's portion of radio frequency conversion costs are to be financed under the Plan on Conversion of Radio Frequency Bands approved by NCCIR.

        On April 22, 2015, NCCIR approved the technical specification on conversion of the radio frequency bands that had been granted to successful bidders. On April 23, 2015, the tender bid winners signed contracts on conversion of radio frequency bands with "special users" (the Ministry of Defense, the Ministry of Internal Affairs and the State Service of Special Communication).

        Our inability to comply with the license conditions may negatively affect our business. In addition, supplementary investment might be required for conversion of radio frequencies and deployment of 3G

services. Either of the foregoing may have a material adverse effect on our business, financial condition, results of operations and prospects.

Failure to renew our licenses or receive renewed or new licenses with similar terms to our existing licenses could have a material adverse effect on our business and results of operations.

        Our telecommunications licenses have their expiration dates in various years from 2016 to 2030. These licenses may be renewed upon application to the relevant governmental authorities. Government officials in Russia and the other CIS countries in which we operate consider the compliance with license requirements as well as the conditions of using the allocated frequency range when deciding whether to renew a license. License renewals may be subject to additional conditions, such as payment obligations or the mandatory modernization of our network.

        In addition, we may be subject to penalties or our licenses may be suspended or terminated for non-compliance with the new license requirements. The suspension or loss of certain licenses could significantly limit our operations and cause certain of our debt to be accelerated.

        The current license to construct and maintain the telecommunication network and provide services with them was granted to MTS Ukraine on July 20, 2010 and terminated on December 3, 2013. On October 15, 2013, NCCIR refused to renew the current license and recommended that MTS Ukraine receive a new license to provide operations in telecommunications sphere. Receiving a new license involves additional costs in comparison with the renewal of the current one and MTS Ukraine filed a lawsuit against NCCIR seeking to declare the failure to renew the license as unlawful. On November 19, 2013, the claims of MTS Ukraine were satisfied and on January 28, 2014, NCCIR prolonged the terms of MTS Ukraine's license for 5 years. At the same time, on January 27, 2014 NCCIR filed an appeal against the decision of the District Administrative Court of Kiev.

        Taking into account possible long-term lawsuits on extension of the license for rendering cellular network services in 2G standard, MTS Ukraine asked NCCIR to provide a new license with no restrictions in special conditions (technologically neutral), which may be used for different technologies—GSM, UMTS and LTE. On January 27, 2015, NCCIR made a decision on granting the license for a 15-year period. Obtaining such license will make it possible for MTS Ukraine to reduce expenses and simplify the process of introduction of new technologies.

        On January 22, 2015, the Supreme Court of Ukraine considered the appeal submitted by NCCIR and cancelled decisions of the Court of Appeal and the District Administrative Court and issued a new court decision rejecting the claim of MTS Ukraine. On March 13, 2015, the District Administrative Court of Kiev accepted the application of NCCIR to overturn the execution of the decision on prolongation of our license for rendering cellular network services in 2G standard. Later the High Administrative Court made a ruling on refusal to overturn the execution of the decision and ordered retrial on the grounds of breach of procedural rules. As of April 1, 2016, the case is being considered in the first instance court.

        Failure to renew our telecommunications licenses or receive renewed or new licenses with similar terms to existing licenses could significantly limit our operations, which could have a material adverse effect on our business, financial condition and results of operations.

        Until March 2014, telecommunications operators carried out activities and received licenses in Crimea in compliance with Ukrainian legislation. However, following the referendum in Crimea on March 16, 2014 in favor of joining the Russian Federation and consequent developments in the region, various countries recognized Crimean secession whereas others did not, therefore, our licensing status in Crimea, as well as the ability to receive continuous cash flow was subject to uncertainty. In addition, due to technical issues that have curtailed our ability to provide telecommunication services to our customers, we suspended our operations in Crimea on August 6, 2014. In October 2014, MTS Ukraine

sold base stations, network infrastructure, IT and telecom equipment and certain other assets located in Crimea through an open tender procedure.

        See also "—Political and Social Risks—Political instability in Ukraine could have a material adverse effect on our operations in Ukraine and on our business, financial condition and results of operations," and "—A deterioration in relations between Russia and other former Soviet republics and/or the United States and the European Union could materially adversely affect our business, financial condition, results of operations and prospects and the value of our shares and ADSs."

If frequencies currently assigned to us are revoked or if we fail to obtain renewals of our frequency allocations, our network capacity will be constrained and our ability to expand limited, resulting in a loss of market share and lower revenues.

        There is a limited number of frequencies available for wireless operators in each of the regions in which we operate or hold licenses to operate. We are dependent on access to adequate spectrum allocation in each market in which we operate in order to maintain and expand our subscriber base. If frequencies are not allocated to us in the future in the required quantities, as well as with the geographic span and for time periods that would allow us to provide wireless services on a commercially feasible basis throughout all of our license areas, our business, financial condition, results of operations and prospects may be materially adversely affected.

        According to the decision of the State Commission for Radio Frequencies No. 13-22-01 dated December 11, 2013, the terms of radio frequency bands usage by radio electronic facilities for mobile communication were supplemented with a requirement to provide the settlements of over 1,000 people with communication services within seven years (depending on the used frequency range). If we are not able to fulfill these requirements, our authorizations for the use of radio frequency spectrum might be either terminated or not prolonged in extrajudicial procedure.

        A loss of allocated spectrum, which is not replaced by other adequate allocations, could also have a substantial adverse impact on our network capacity. In addition, frequency allocations are often issued for periods that are shorter than the terms of the licenses, and such allocations may not be renewed in a timely manner or at all. If our frequencies are revoked or we are unable to renew our frequency allocations, our network capacity would be constrained and our ability to expand limited, resulting in a loss of market share and lower revenues.

An increase in the fees for frequency spectrum usage could have a negative effect on our financial results.

        The terms of our licenses in Russia and the CIS require that we make payments for frequency spectrum usage. Any significant increase in the fees payable for the frequency channels that we use or additional frequency channels that we need in Russia or the CIS could have a negative effect on our financial results.

        On December 31, 2014, a new procedure of payment for frequency spectrum usage came into force. According to the newly adopted amendments, the fees for frequency spectrum usage are calculated based on the total frequency band allocated to each operator in each region with such frequency spectrum usage determined with reference to the decision of the State Commission for Radio Frequencies, frequency allocation decisions or to the license conditions. To implement this principle, on November 13, 2013, Governmental Regulation No. 1017 was adopted, which amends the Regulation of the Government of the Russian Federation No. 171 dated March 16, 2011 "On establishing of a single fee and an annual fee for the use of radio frequency spectrum of the Russian Federation and on collection of such fees."

        Furthermore, the order of the Ministry of Communications No. 279 dated September 4, 2014 introduced corresponding amendments into the "Methodology of calculation of a single fee and annual

fee for the use of the radio spectrum of the Russian Federation," approved by the order of the Ministry of Communications dated June 30, 2011 No. 164. Fees are directly calculated according to this methodology. Under the new order, rates and coefficients are subject to revision at least once every two years. There were no changes in rates and coefficients in 2015. In case the rates are raised in 2016, this could result in additional costs.

        Similarly, in April 2010, the Cabinet of Ministers of Ukraine significantly increased the fees for frequency spectrum usage in Ukraine for cellular communications. Furthermore, according to the Tax Code of Ukraine, the fees payable for frequency usage were to be determined based in part on the rate of inflation and reviewed annually effective January 1, 2011. Accordingly, the fees for frequency usage were increased by 8.9% in 2012 as compared to 2011, by 8% in 2013 as compared to 2012, and were doubled from April 1, 2014 as compared to 2013. Commencing January 1, 2015 fee for radio spectrum usage has been transformed into rent payment (fee amount remained unchanged). When adopting a state budget for 2016, the Verkhovna Rada introduced a number of amendments to the Tax Code of Ukraine, including the increase in rental payment for radio spectrum usage by 13.35% commencing January 1, 2016.

If we are unable to maintain our favorable brand image, we may be unable to attract new subscribers and retain existing subscribers, which may lead to loss of market share and revenues.

        Developing and maintaining awareness of our brands is critical to informing and educating the public about our current and future services and is an important element in attracting new subscribers. We believe that the importance of brand recognition is increasing as our markets become more competitive. Successful promotion of our brands will depend largely on the effectiveness of our marketing efforts and on our ability to provide reliable and useful products and services at competitive prices. Brand promotion activities may not yield increased operating revenues, and even if they do, such operating revenues may not offset the operating expenses we incur in building our brands. Furthermore, our ability to attract new subscribers and retain existing subscribers depends, in part, on our ability to maintain what we believe to be our favorable brand image. Negative publicity or rumors regarding our company, our shareholders and affiliates or our services could negatively affect this brand image, which could lead to loss of market share and revenues. Our failure to successfully and efficiently promote and maintain our brands may limit our ability to attract new subscribers and retain our existing subscribers and materially adversely affect our business and results of operations.

We engage in transactions with related parties, which may present conflicts of interest, potentially resulting in the conclusion of transactions on terms not determined by market forces.

        We have purchased interests in various companies from Sistema and entered into agreements with affiliates within the Sistema group for the provision of advertising services (Advertising Agency Maxima OJSC ("Maxima")), connectivity facilities and telephone numbering capacity (MGTS), IT services and hardware purchases (Sitronics Telecom Solutions JSC, Sitronics Smart Technologies LLC, NVision Special Projects LLC and NVision Group), banking services (MTS Bank, formerly Moscow Bank of Reconstruction and Development ("MBRD")), telecommunication services (Stream LLC), medical services (Medsi Group CJSC), the billing system development and IT integration services (NVision JSC, Sitronics Telecom Solutions JSC and other entities of NVision Group), maintenance of the residential and commercial real estate (CITY-TELECOM CJSC) and other services. Related party transactions with Sistema and other companies within Sistema group may present conflicts of interest, potentially resulting in the conclusion of transactions on terms not determined by market forces. See "Item 7. Major Shareholders and Related Party Transactions—B. Related Party Transactions."

In the event that our minority shareholders or the minority shareholders of our subsidiaries were to successfully challenge past or future interested party transactions, or do not approve interested party transactions or other matters in the future, we could be limited in our operational flexibility and our business, financial condition, results of operations and prospects could be materially adversely affected.

        We own less than 100% of the equity interests in some of our subsidiaries. In addition, certain of our wholly owned subsidiaries have had other shareholders in the past. We and our subsidiaries in the past have carried out, and continue to carry out, transactions that may be considered to be "interested party transactions" under Russian law, requiring approval by disinterested directors, disinterested independent directors or disinterested shareholders depending on the nature of the transaction and parties involved. The provisions of Russian law defining which transactions must be approved as "interested party transactions" are subject to different interpretations and, as a result, it is possible that our and our subsidiaries' interpretation and application of these provisions could be subject to challenge. Any such challenges, if successful, could result in the invalidation of transactions, which could have a material adverse effect on our business, financial condition, results of operations and prospects.

        In addition, Russian law requires a three-quarters majority vote of the holders of voting stock present at a shareholders' meeting to approve certain transactions and other matters, including, for example, charter amendments, major transactions involving assets in excess of 50% of the assets of the company, repurchase of shares by the company and certain share issuances. In some cases, minority shareholders may not approve interested party transactions requiring their approval or other matters requiring minority shareholder or supermajority approval. In the event that these minority shareholders were to successfully challenge past interested party transactions, or do not approve interested party transactions or other matters in the future, we could be limited in our operational flexibility and our business, financial condition, results of operations and prospects could be materially adversely affected.

Our competitive position and future prospects depend on our senior managers and other key personnel and our inability to attract, retain and motivate qualified key personnel could have a material adverse effect on our business, financial condition and results of operations.

        Our ability to maintain our competitive position and to implement our business strategy is dependent to a large degree on the services of our senior management team and other key personnel. Moreover, competition in Russia and in the other countries where we operate for personnel with relevant expertise is intense due to the relatively small number of qualified individuals. As a result, we attempt to structure our compensation packages in a manner consistent with the evolving standards of the labor markets in these countries. We are not insured against the detrimental effects to our business resulting from the loss or dismissal of our key personnel. In addition, it is not common practice in Russia and the other countries where we operate to purchase key-man insurance policies, and we do not carry such policies for our senior management and other key personnel. The loss or decline in services of members of our senior management team or an inability to attract, retain and motivate qualified key personnel could have a material adverse effect on our business, financial condition and results of operations.

The entry of mobile virtual network operators into the Russian mobile communications market could increase competition and subscriber churn, resulting in a loss of our market share and decreased revenue.

        On December 29, 2008, the Ministry of Communications and Mass Media adopted an order establishing the requirements for mobile virtual network operators ("MVNOs"). MVNOs are companies that provide mobile communications services but do not own the radio frequencies and, often, the network infrastructure required to do so. According to the order, MVNOs in Russia must be licensed, and their use of frequencies and infrastructure and rendering of services is to be done pursuant to agreements entered into between MVNOs and existing frequency holders. There is no

26

Table of Contents

requirement that existing frequency holders have to obligatory transact and enter into agreements with the MVNOs.

        The aim of the Ministry in establishing the legal framework for MVNOs to operate is to increase competition in the Russian mobile services market, which is currently dominated by us, VimpelCom and MegaFon. While existing frequency holders, including us, may receive revenues from MVNOs for the use of our frequencies and network infrastructure, we expect these revenues to be lower than the revenues we would receive if providing services directly to subscribers. In addition, in the event we lose subscribers to MVNOs that lease their frequencies and infrastructure from an operator other than us, we will be deprived of the revenue streams from both the subscribers and the MVNOs. The MVNOs may also establish aggressive tariffs, which could result in increased subscriber churn and/or driving down the tariffs of all mobile operators.

        In December 2011, Scartel reached an agreement with MegaFon and Rostelecom to allow them to provide LTE services through Scartel's network in exchange for permitting Scartel to use the two companies' network infrastructure. In February 2012, Scartel and MegaFon received the necessary licenses to allow MegaFon to provide such services over the Scartel LTE network.

        In February 2014, the Russian Government approved a "Development of competition in telecommunications" roadmap, which provides for the preparation of a report on realization of the MVNO business model. Following the Government Commission on Communication meeting, which was held on June 6, 2014, regarding "development of "virtual operators" institute of mobile radio telephone communication in the Russian Federation," the deputy Minister on Communication noted that MNVO operators should be regulated by the market and that no additional restrictive regulation is required. At the same time, the Ministry of Communication of the Russian Federation proposed to develop and adopt an order stipulating requirements on rendering data transmission services and telematics communication services when using a business model of virtual data transmission networks. As of April 1, 2016, this order of the Ministry of Communications of the Russian Federation has not been adopted.

        In April 2014, it was announced that Scartel launched the federal mobile operator (under the Yota brand), providing subscribers with 2G, 3G and 4G coverages. The operator provides voice and SMS services on MegaFon's network via MVNO. In September 2014, MGTS started to provide mobile services in Moscow on the basis of our infrastructure.

        The emergence of any new MVNO operators in the market or any of the foregoing trends could increase market competition and subscriber churn and, as a result, have a material adverse effect on our business, financial condition, results of operations and prospects.

A finding by FAS that we have acted in contravention of antimonopoly legislation could have a material adverse effect on our business, financial condition and results of operation.

        Our businesses have grown substantially through the acquisition and formation of companies, many of which required the prior approval of, or subsequent notification to, FAS or its predecessor agencies. In part, relevant legislation in certain cases restricts the acquisition or formation of companies by groups of companies or individuals acting in concert without such prior FAS approval. While we believe that we have complied with the applicable legislation for our acquisitions and formation of new companies, this legislation is sometimes vague and subject to varying interpretations. If FAS were to conclude that our acquisition or formation of a new company was done in contravention of applicable legislation, it could impose administrative sanctions and require the divestiture of such company or other assets, which could have a material adverse effect on our business, financial condition and results of operations.

        In October 2010, FAS found that we, VimpelCom and MegaFon violated antimonopoly laws on competition relating to our pricing for roaming services. As a result, FAS imposed an administrative fine on us in the amount of RUB 21.9 million which represents 1.0% of the revenues we derived from roaming services in CIS countries in 2009. We paid the fine imposed on us by FAS on March 28, 2011.

        In addition, in October 2011, FAS began an investigation of our and VimpelCom's actions, suspecting violation of antimonopoly laws by coordinated pricing of iPhone 4 handsets. On April 26, 2012 we and VimpelCom were found to be in violation of the Competition law through coordinating prices from September 2010 through April 2011, however, FAS also noted that these violations were voluntarily rectified, and terminated the proceedings as a result. On July 17, 2012, FAS imposed a turn-over based fine of RUB 16.9 million on us, which we complied with.

        In November 2012, FAS began an investigation of the contractual relationship between operators and content providers and in December 2012 issued a warning to us and VimpelCom requesting each of us to cease the violation of antimonopoly laws, particularly relating, to solicitation of services to the subscribers. We and VimpelCom complied with the requirements and on February 7, 2013, FAS closed the case.

        In October 2013, the FAS regional office in the Pskov Region began an investigation in relation to an alleged violation by us, VimpelCom and MegaFon of antimonopoly law by coordinating pricing of the mobile data services on the territory of Pskov Region. The investigation was terminated in December 2013 due to the absence of breach of antimonopoly law of mobile operators.

        On November 23, 2015, FAS regional office in Moscow found MGTS in violation of antimonopoly law by setting different prices for certain services for state-funded and commercial organizations. The administrative proceedings to determine the fine are expected.

        On December 31, 2015, FAS began an investigation in relation to an alleged violation by us, VimpelCom, and MegaFon of antimonopoly law by increase of prices for mass SMS deliveries. The first committee meeting was tentatively scheduled for March 2016. On March 31, 2016, it was declared that the case was tentatively postponed for one month.

        If FAS finds our actions insufficient to rectify past violations of antimonopoly laws or issues new warnings and requests in the future, inter alia, in other regions, this could have a material adverse effect on our business, financial condition, results of operations and prospects.

A finding by the AMC that we have acted in contravention of antimonopoly legislation could have a material adverse effect on our business, financial condition and results of operations.

        Under Ukrainian legislation, a company which is found to have acted in contravention to antimonopoly legislation, may be subject to fines and claims from the AMC. For example, in December 2011, the AMC opened an investigation into whether MTS Ukraine violated antimonopoly legislation with its pricing of international roaming services. The AMC stated that the average price of international roaming services offered by MTS Ukraine and its roaming partners was higher than the corresponding prices in the European Union, which might demonstrate that the prices charged by MTS Ukraine were not economically justified. The investigation aimed to examine whether MTS Ukraine used its dominant position in the Ukrainian telecommunications market to establish prices that would not be possible if there was significant competition on the telecommunications market. Although we believe that we did not violate antimonopoly laws, we could be liable for up to 10% of MTS Ukraine revenues. In December, 2012 the AMC issued obligatory recommendations to MTS Ukraine and Kyivstar to lower the prices both for international roaming services and national mobile services. In December 2012 MTS Ukraine submitted a report discussing the implementation of these recommendations and in January 2013, both claims of AMC were dismissed and no penalties were imposed on us. However, the AMC may determine that we violated antimonopoly legislation in this or

any other matters, and may impose fines on us, which may have a material adverse effect on our business, financial condition and results of operation. In addition, we may be required to adjust the prices that we charge for international roaming services, which may adversely affect our revenues. See also "—Governmental regulation of SMP operators in Ukraine could adversely affect our results of operations" and "Item 4. Information on Our Company—B. Business Overview—Regulation of Telecommunications in the Russian Federation and Ukraine—Regulation in Ukraine—Competition" for additional information.

If we are found to have a dominant position in the markets where we operate, the government may influence our subscriber tariffs and restrict our operations.

        Under Russian legislation, a company controlling between 35%-50% or over 50% of a market or otherwise able to control market conditions may be found by FAS as dominant in such market. Moreover, under Russian antimonopoly regulations any three companies collectively holding a market share of over 50% or five companies collectively holding a market share of over 70%, and in each case over 8% individually, can be found to have a dominant position on a certain market. However, Russian law provides for industry-specific rules in accordance with which a company could be categorized as dominant even if its share of the corresponding market is less than 35%. In addition companies recognized as natural monopolies are also considered to have a dominant position on the respective market. Companies controlling over 35% or otherwise occupying a dominant position on the market were previously listed by FAS in a special register and could become subject to special monitoring and reporting requirements with respect to such markets. According to the amendments to the Federal Law No. 135 "On the Protection of Competition" introduced by the Federal Law No. 275 dated October 5, 2015 since January 5, 2016 a business entity whose market share is less than 35%, however exceeds the shares of the market participants cannot be recognized by FAS as occupying a dominant position. Also the regulations in relation to a special register of business entities having more than 35% of a certain commodity market or otherwise occupying a dominant position on the market were repealed. At the same time FAS is still allowed to conduct analysis of market condition in order to establish the dominant position of a business entity. Current Russian legislation does not clearly define "market" in terms of the types of services or the geographic area.

        One of our subsidiaries, MGTS, was categorized by the Federal Tariff Service as a natural monopoly in the Moscow telecommunications market. As a result, MGTS' tariffs are subject to regulation by FAS (previously regulated by the Federal Tariff Service). Another of our subsidiaries, Comstar-Regions, that was operating in Khanty Mansiysk Autonomous District-Yugra among others, was also categorized as a natural monopoly in the public telecommunications market up until November 24, 2015, when it was excluded from the Register of Natural Monopolies. See also "—MGTS is subject to extensive regulation of tariffs, and these tariffs may not fully compensate us for the cost of providing required services."

        As of December 31, 2015, we were also found by FAS to be a company with a market share exceeding 35% in the communications market in the Ivanovo Region, Kurgan Region, Magadan Region, Sakhalin Region, Nenets Autonomous District and Udmurt Republic. However, the regulations in relation to the register of business entities having more than 35% of a certain commodity market were repealed due to the abovementioned amendments. In the event that we are found in the future to have a dominant position and are determined to abuse the dominant position on these or any additional markets, FAS would have the right to impose certain restrictions provided for under the antimonopoly laws, including a mandated reduction in our tariffs, and FAS would have the right to impose certain restrictions on our operations in such markets. In addition, if we are found in the future to have a dominant position with a market share exceeding 70% and are determined to abuse the dominant position, the Russian Government would have the right to determine the rules of non-discriminatory access to goods or services offered by us with which we would be obliged to comply.

See "Item 4. Information on Our Company—B. Business Overview—Regulation of Telecommunications in the Russian Federation and Ukraine—Regulation in the Russian Federation—Competition, Interconnect and Pricing" for additional information.

        In case we are found to have dominant position, we can also be subject to penalties and a turn-over based fine may be imposed on us in relation to certain violations of antimonopoly law. The level of fine is from 1% to 15% of revenue on the market where the violation was conducted, with 8% being the base level of the fine.

        Additionally, MTS Ukraine, was found to be a company with a dominant position in the telecommunications market and is subject to certain government imposed restrictions, including limitations on the interconnect rates it can charge other operators. See "—Governmental regulation of SMP operators in Ukraine could adversely affect our results of operations" and "Item 4. Information on Our Company—B. Business Overview—Regulation of Telecommunications in the Russian Federation and Ukraine—Regulation in Ukraine—Competition" for additional information.

        If we or any of our subsidiaries were to be found by FAS (or the AMC with respect to our operations in Ukraine) to be business entities occupying a dominant market position, FAS (or the AMC, as the case may be) would have the power to impose certain restrictions on our or their businesses. In particular, the authorities may impose on us tariffs at levels that could be competitively disadvantageous. If we or any of our subsidiaries were to be found by FAS to be business entities occupying a dominant market position with a market share exceeding 70% and are determined to abuse the dominant position, the Russian Government would have the right to determine the rules of nondiscriminatory access to goods or services offered by us. Additionally, geographic restrictions on our expansion could reduce our subscriber base and prevent us from fully implementing our business strategy, which may materially adversely affect our business, financial condition, results of operations and prospects.

If we or any of our mobile operator subsidiaries operating in Russia are identified as an operator occupying a "substantial position," the regulator may reduce our interconnect tariffs which, in turn, may have a material adverse effect on our financial condition and results of operations.

        In addition to the regulation of dominant operators by FAS, the Federal Law on Communications provides for the special regulation of telecommunications operators occupying a "substantial position," i.e., operators which, together with their affiliates, have 25% or more of installed capacity or capacity to carry out transmission of not less than 25% of traffic in a geographically defined zone within the Russian Federation. These regulations provide for governmental regulation of the key terms of such operators' interconnect agreements, including the interconnect tariffs. In addition, such operators are required to develop standard key terms of interconnect agreements and publish them as a public offer made to all operators who intend to interconnect to the networks of those operators. For additional information, see "Item 4. Information on Our Company—B. Business Overview—Regulation of Telecommunications in the Russian Federation and Ukraine—Regulation in the Russian Federation."

        At present, the foregoing regulations apply only to fixed line operators in Russia and therefore apply to our fixed line business. Draft legislation was introduced in 2008 that would extend the law to apply to mobile operators. Although the proposed law was not adopted, the risk that similar legislation will be introduced and adopted in the future remains. If legislation which extends the foregoing regulations to apply to mobile operators is adopted, and we and any of our mobile operator subsidiaries operating in Russia are identified as operators occupying a "substantial position," regulators may reduce our interconnect tariffs which, in turn, may have a material adverse effect on our revenues, financial condition and results of operations.

        In addition, MGTS is categorized as fixed line operator occupying a substantial position in the Moscow telecommunications market and therefore its interconnect tariffs are subject to state

regulation. In February 2013, Comstar-UTS was excluded from the List of "substantial operators" in Moscow and MTS was not included therein. There is however a probability that we could be categorized as fixed line operator occupying a substantial position in Moscow due to our affiliation with MGTS and because of our integration with Comstar-UTS. As a result of the state regulation of the relevant interconnection rates, substantial operators may be unable to increase these in line with economic developments or any increases of our relevant costs, resulting in a material adverse effect on our financial condition and results of operations. See also "—MGTS is subject to extensive regulation of tariffs, and these tariffs may not fully compensate us for the cost of providing required services."

MGTS is subject to extensive regulation of tariffs, and these tariffs may not fully compensate us for the cost of providing required services.

        In addition to holding substantial position in the Moscow telecommunication market, MGTS is included into the Register of natural monopolies in the telecommunications market. Consequently, tariffs for basic services rendered to public switched telephone networks subscribers (fees for providing access to a local telecommunication network, monthly fees for granting subscriber line in a constant use, monthly fees for providing local telephone connection) are subject to regulation.

        lthough MGTS is permitted to petition FAS for increases in tariffs based on such criteria as inflation, increased costs and the need for network investments, it is possible that future requested increases may not be granted or that FAS may not adequately take such factors into account in setting tariffs. If the permissible tariffs applicable to MGTS do not compensate MGTS for the cost of providing services, the business and results of operations could be materially adversely affected. See also "—If we or any of our mobile operator subsidiaries operating in Russia are identified as an operator occupying a "substantial position," the regulator may reduce our interconnect tariffs which, in turn, may have a material adverse effect on our financial condition and results of operations."

Changes to the rules and regulations involving roaming charges in Russia may adversely affect our financial condition and results of operations.

        Several draft laws were submitted for consideration to the State Duma, which were intended to change the regulation of roaming services in Russia by eliminating/ reducing intra-network roaming tariffs for incoming and outgoing calls. In January 2016, the State Duma rejected the initiative in its first reading. However, if similar draft laws are proposed and adopted in the future, we believe that our revenues from the provision of roaming services would decline, which could have a material adverse effect on our financial condition and results of operations.

        See also "—A finding by FAS that we have acted in contravention of antimonopoly legislation could have a material adverse effect on our business, financial condition and results of operation."

Compliance with the new regulations on International Mobile Equipment Identity ("IMEI") numbers may present us with technical difficulties and may lead to the expenditure of significant resources.

        A draft law that enables each mobile communications subscriber to register the user terminal free-of-charge on a database maintained by the operator, chiefly to prevent their unlawful use was previously considered in Ukraine. Aimed at discouraging theft, the draft law obligated operators to suspend or block the traffic transmission of the terminal upon the application of subscriber. In July 2015, the draft law was withdrawn from consideration. A similar draft law was rejected by the Russian State Duma. If a similar initiative is proposed in the future, we may be required to develop a system to monitor IMEI numbers, and we may need to establish and maintain a database of IMEI numbers, which would necessitate the expenditure of significant technical and financial resources.

The accession of Russia into the World Trade Organization ("WTO") may lead to legislative and other changes which may adversely affect our business, financial condition and results of operation.

        On December 16, 2011, Russia signed the accession protocol in order to enter into the WTO which was ratified by Federal Law on July 21, 2012 and became mandatory law in Russia. This may lead to potentially significant changes in Russian legislation including, among others, regulation of foreign investments in Russian companies, competition laws, telecommunications laws, changes in the taxation system and customs regulations in Russia. In addition, the implementation of the WTO rules may lead to the increase of competition on the markets where we operate. If new legislation is implemented in Russia as a result of accession to the WTO and there is an increase in competition, this could have a material adverse effect on our financial condition and results of operations.

We may be required to make significant investments beyond those that are currently planned to preserve our competitive advantage in response to the rapid evolution of fixed network technology (inter alia our subsidiaries, for example MGTS).

        MGTS accomplishes a number of projects aimed at developing communication networks and expanding availability of telecommunication services for customers. The company is currently at the final stage of building broadband optical networks employing the Gigabit-capable Passive Optical Network ("GPON") technology with direct connection of subscribers to an optical network. The applied part of the GPON project progress is the creation of a digital platform, which enables MGTS to render an enlarged range of services, including services for B2G segment. There is a qualitative leap for providing services of processing video and video analytics from rendering video signal transportation services (from surveillance cameras to a uniform data storage center). Possible deficiency of free cash during the current economic downturn might lead to freeze of investment programs for development of new products and services, upgrade of the existing network, decrease in quantity of construction objects, cutbacks in development programs in New Moscow and Moscow region.

        In addition, MGTS attracts contractors for construction and upgrade of its network. In case a contractor faces lack of own current assets, lack of advance payments or external finance sources, it may not fulfill contractual obligations, which could lead to penalties from MGTS, termination of contracts or contractor's bankruptcy. This factor may negatively affect the terms of MGTS projects implementation and lead to higher expenses for arrangement of purchases from other market participants.

        MGTS invested approximately RUB 11.980 billion in 2014 and RUB 8.861 billion in 2015 to upgrade its infrastructure. If MGTS is not able to expand its network infrastructure in a timely manner and to offer new services or if it is required to make significant investments beyond those that are currently planned, our business, financial condition, results of operations and prospects could be materially adversely affected.

Our intellectual property rights are costly and difficult to protect.

        We regard our copyrights, trademarks, trade secrets and similar intellectual property, including our rights to certain domain names, as important to our continued success. We rely upon trademark and copyright law, trade secret protection and confidentiality or license agreements with our employees, customers, partners and others to protect our proprietary rights. Nonetheless, intellectual property rights are especially difficult to protect in the markets where we operate. In these markets, the regulatory agencies charged with protecting intellectual property rights are inadequately funded, legislation is underdeveloped, piracy is commonplace and enforcement of court decisions is difficult.

        A special court for intellectual property began operating in July 2013 as a new body in the system of Arbitrazh court for dealing with cases relating to protection of intellectual property. It is too early to say how it will influence the quality of protection of intellectual property rights in Russia.

32

Table of Contents

        In addition, litigation may be necessary to enforce our intellectual property rights, to determine the validity and scope of the proprietary rights of others, or to defend against claims of infringement. Any such litigation may result in substantial costs and diversion of resources, and, if decided unfavorably to us, could have a material adverse effect on our business and results of operations. We also may incur substantial acquisition or settlement costs where doing so would strengthen or expand our intellectual property rights or limit our exposure to intellectual property claims of third parties. See also "Item 8. Financial Information—A. Consolidated Statements and Other Financial Information—7. Litigation—Other litigation."

        Due to adoption of the Federal Law No. 35 dated March 12, 2014, which introduced significant amendments to the fourth part of the Civil Code of the Russian Federation, the rules of intellectual property rights regulation changed. Lack of law enforcement practice of the changed provisions of the Civil Code may cause difficulties in protection of our rights and legitimate interests.

Changes that are being implemented in current sales and customer care processes of MTS, creation of new information technology services, migration of fixed B2B and B2C subscribers to a single information technology solution may destabilize our information technology solutions, which could have a material adverse effect on our business and results of operations.

        Changes in current sales and customer care processes, creation of new information technology services, migration of fixed B2B and B2C subscribers to a single information technology solution may increase our operational risks and expenses and inconvenience subscribers. The failure or breakdown of key components of our infrastructure in the future, including our billing system and its susceptibility to fraud, could have a material adverse effect on our business and results of operations.

If leaks of confidential information, including information relating to our subscribers, occur it may negatively impact our reputation and our brand image and lead to a loss of market share, which could materially adversely affect our business, financial condition, results of operations and prospects.

        Although we make efforts to protect confidential information, breaches of security and leaks of confidential information, including information relating to our subscribers, may negatively impact our reputation and our brand image and result in a loss of market share or otherwise have a material adverse effect on our business, financial condition and results of operations. For example, in January 2003, part of our database of subscribers, containing private subscriber information, was illegally copied and stolen. In addition, in May 2003, certain subscriber databases of several operators in the North-West Region, including those of us, MegaFon, Delta Telecom and two other operators, were stolen. In each case, the stolen databases were thereafter available for sale in Russia. Despite the measures taken, we cannot completely exclude the possibility of such incidents in the future. See also "—Legal Risks and Uncertainties—Our failure to comply with new personal data protection laws and with the regulations of state authorities regarding information security in the telecommunications networks in Russia may have a material adverse effect on our business, financial condition and results of operations."

Alleged medical risks of cellular technology may subject us to negative publicity or litigation, decrease our access to base station sites, diminish subscriber usage and hinder access to additional financing.

        Electromagnetic emissions from transmitter masts and mobile handsets may harm the health of individuals exposed for long periods of time to these emissions. The actual or perceived health risks of transmitter masts and mobile handsets could materially adversely affect us or our subsidiaries by reducing subscriber growth, reducing usage per subscriber, increasing the number of product liability lawsuits, increasing the difficulty in obtaining or maintaining sites for base stations and/or reducing the financing available to the wireless communications industry. Each of these potential circumstances may adversely affect our business, financial condition, results of operations and prospects.

        Under the draft law on "Defending against negative electromagnetic emissions from base stations of mobile network" which was proposed in Ukraine in December 2013, a mobile phone base station was classified as a potentially hazardous object. To date the draft law is excluded from the agenda. The installation of base stations was assumed to be made taking into account an environmental impact assessment at the expense of operators and a base station's operations could be terminated if a hazardous effect on health was established. If a similar initiative is proposed and adopted in the future it may lead to an increase in the costs of deploying base stations and raise the maintenance costs of MTS Ukraine.

Risks Relating to our Financial Condition

We may be adversely affected by the current economic environment.

        As a result of the credit market crisis (including uncertainties with respect to financial institutions and the global capital markets), decreased prices for major export commodities (including oil and metals) and other macro-economic challenges currently affecting many of the economies in which we operate, our subscribers' disposable incomes and our vendors' cash flows may be adversely impacted. Consequently, subscribers may modify or decrease their usage of our services or fail to pay the outstanding balances on their accounts, and vendors may significantly increase their prices, eliminate vendor financing or reduce their output.

        We may also experience increases in accounts receivable and bad debt among corporate subscribers, some of whom may face liquidity problems and potential bankruptcy, as well as the potential bankruptcy of our corporate partners. The deterioration of economies in the countries of our operation may lead, inter alia, to insolvency of financial institutions, which in turn may impact our business and financial condition.

        The strained political situation in Ukraine coupled with an economic downturn resulted in financial difficulties in the banking system, including notably liquidity risks. As we hold the bulk of excess hryvnia and foreign currency cash in Ukrainian banks, a banking crisis or the bankruptcy or insolvency of the banks from which we receive or with which we hold our funds could result in the loss of our deposits or affect our ability to complete banking transactions in Ukraine, which could have a material adverse effect on our business, financial condition and results of operations. For example, we incurred a charge to operating income for the fourth quarter 2014 due to losses stemming from the insolvency of DeltaBank in Ukraine. During the year ended December 31, 2015, the Group created additional reserve for cash balances deposited in distressed Ukrainian banks which was included as a component of operating expenses in the accompanying consolidated statement of profit or loss. See also Note 29 to our audited consolidated financial statements.

        See also "—Inflation could increase our costs and adversely affect our results of operations."

        A decline in subscriber usage, an increase in bad debts, material changes in equipment pricing or financing terms or the potential bankruptcy of our corporate subscribers or partners may have a material adverse effect on our business, financial condition, results of operations and prospects.

        In addition, a deterioration in macroeconomic conditions could require us to reassess the value of goodwill on certain of our assets, recorded as a difference between the fair value of the assets of business acquired and its purchase price. This goodwill is subject to impairment tests on an ongoing basis. The weakening macroeconomic conditions in the countries in which we operate and/or a significant difference between the performance of an acquired company and the business case assumed at the time of acquisition could require us to write down the value of the goodwill or portion of such value. Future write downs relating to the value of the goodwill or portion of such value could have a material adverse effect on our financial condition and results of operations.

Continued turmoil in the credit markets could cause our business, financial condition, results of operations and the value of our shares and ADSs to suffer.

        Sanctions introduced by the United States and the European Union with respect to the Russian Federation coupled with an economic downturn and decline in global oil prices caused significant capital outflow, ruble depreciation, rise of credit rates in the domestic market and lack of available financing. A majority of Russian companies continue to experience difficulties accessing their cash equivalents, trading investment securities, drawing on revolvers, issuing debt and raising capital generally. For the period of 2015, the Central Bank of Russia cut the key rate from 17% to 11%, however its further reduction is aggravated by stressful economic situation and high inflationary risks.

        A continuation or repetition of this downturn in the global financial markets as well as toughening or extension of international sanctions against Russia and resulting volatility of the trading price of our shares and ADSs may negatively impact our ability to obtain financing on commercially reasonable terms either on foreign or domestic markets and could have a material adverse effect on our business, financial condition, results of operations and prospects.

Our inability to generate sufficient free cash flow to satisfy our debt service obligations or to refinance debt on commercially reasonable terms, could materially adversely affect our business, financial condition, results of operations and prospects.

        We have a substantial amount of outstanding indebtedness, primarily consisting of the obligations we entered into in connection with our notes and bank loans. As of December 31, 2015, our consolidated total debt, including capital lease obligations, was RUB 345,869 million. Our interest expense for the year ended December 31, 2015 was RUB 26,630 million, net of amounts capitalized.

        Our ability to service, repay and refinance our indebtedness and to fund planned capital expenditures will depend on our ability to generate cash in the future. This, to a certain extent, is subject to general economic, financial, competitive, legislative, regulatory and other factors that are beyond our control. If we are unable to generate sufficient cash flow or otherwise obtain funds necessary to make required payments, we may default under the terms of our financial indebtedness, and the holders of our indebtedness would be able to accelerate the maturity of such indebtedness, potentially causing cross-defaults under and acceleration of our other indebtedness. The existing debt service is becoming more complicated due to our dependence on floating interest rates on the financial markets.

        We may not be able to generate sufficient cash flow or access international or domestic capital markets or incur additional loans to enable us to service or repay our indebtedness or to fund our other liquidity needs. We may be required to refinance all or a portion of our indebtedness on or before maturity for a number of reasons; for example, the terms of some of our loan agreements may require us to prepay the loan in certain circumstances, such as a deterioration in our credit rating, we are delisted or our retained earnings drop below a certain level. This, in turn, may force us to sell assets, reduce or delay capital expenditures or seek additional capital. Refinancing or additional financing may not be available on commercially reasonable terms or at all, and we may not be able to sell our assets or, if sold, the proceeds therefrom may not be sufficient to meet our debt service obligations. Our inability to generate sufficient cash flow to satisfy our debt service obligations, or to refinance debt on commercially reasonable terms, would materially adversely affect our business, financial condition, results of operations and prospects. See "Item 5. Operating and Financial Review and Prospects—B. Liquidity and Capital Resources."

Ruble depreciation and regulatory changes in foreign currency regulation could increase our costs, decrease our available funds, or make it more difficult for us to comply with financial covenants and to repay our debts and would affect the value of dividends received by holders of ADSs.

        Over the period of 2015, the ruble's depreciation against the U.S. dollar has continued and it has experienced high volatility. Such dynamics are explained by external geopolitical factors, limited financial markets, decrease in oil prices, international ratings agencies' downgrades of Russia's sovereign rating, reduction in internal consumption and other factors that have directly or indirectly affected the ruble.

        For example, on December 31, 2013, the official exchange rate published by the CBR was 32.73 rubles per U.S. dollar. The ruble continued to depreciate against the U.S. dollar reaching 56.26 rubles per one U.S. dollar on December 31, 2014, whereas on December 31, 2015, it increased to 72.88 rubles per one U.S. dollar.

        The ruble has also depreciated against the euro. On December 31, 2013, the official exchange rate was 44.97 rubles per one euro. As of December, 31, 2014 the exchange rate was 68.34 rubles per one euro whereas on December 31, 2015 it increased to 79.70 rubles per one euro. See also "—Changes in the exchange rate of local currencies in the countries where we operate against the Russian ruble could adversely impact our revenues reported in Russian rubles as well as changes in the exchange rate of the Russian ruble and local currencies against the U.S. dollar and/or euro could adversely impact our costs in terms of the Russian ruble and local currencies."

        Currently, the Russian foreign currency market is regulated by legislation, which is aimed at liberalization of currency regulation and lowering of administrative barriers. This legislation provides a general framework and a set of rules, within which both the Russian government and the CBR are authorized to propose various regulations, which may result in uncertainty for us in carrying out importation of equipment. In 2015, the CBR almost practically ceased currency interventions aimed at the ruble exchange rate stabilization and limited its activity by absorbing the dollar liquidity in June-July, 2015. Despite the strategy directed to increase the ruble exchange rate flexibility and limitation of the daily volume of operations with foreign currency to 350 million U.S. dollars, the CBR has an option to intervene additionally in the domestic foreign exchange market in case of financial instability. The stability of the ruble will depend on many political and economic factors. These include the ability of the government to finance the state budget without recourse to monetary emissions, to control the level of interest rates and inflation. Furthermore, changes in foreign currency regulation may affect our ability to fund payments denominated in foreign currency and result in us entering into supplementary agreements with our foreign counterparts.

        A significant portion of our capital expenditure and liabilities and borrowings are either denominated in or tightly linked to the U.S. dollar. Conversely, a majority of our revenues are denominated in rubles. As a result, devaluation of the ruble against the U.S. dollar can adversely affect us by increasing our costs in rubles, both in absolute terms and relative to our revenues, and make it more difficult to comply with the financial ratios contained in our various loan agreements or fund cash payments on our indebtedness on time. It also reduces the U.S. dollar value of tax savings arising from tax incentives for capital investment and the depreciation of our property, plant and equipment, since their basis for tax purposes is denominated in rubles at the time of the investment. Increased tax liability would also increase total expenses, which would have an adverse impact on our results.

        We also anticipate that any dividends we may pay in the future on the shares represented by the ADSs will be declared and paid to the depositary in rubles and will be converted into U.S. dollars by the depositary and distributed to holders of the ADSs. Accordingly, the value of dividends received by holders of ADSs will be subject to fluctuations in the exchange rate between the ruble and the U.S. dollar. Depreciation of the ruble against the U.S. dollar could therefore materially adversely affect our

financial condition, results of operations and prospects and the value of the ADSs. See also "Item 11. Quantitative and Qualitative Disclosures about Market Risk—Foreign Currency Risk."

Changes in the exchange rate of local currencies in the countries where we operate against the Russian ruble could adversely impact our revenues reported in Russian rubles as well as changes in the exchange rate of the Russian ruble and local currencies against the U.S. dollar and/or euro could adversely impact our costs in terms of the Russian ruble and local currencies.

        A significant portion of our expenditures and liabilities, including capital expenditures and borrowings (including our U.S. dollar denominated notes), are either denominated in, or closely linked to, the U.S. dollar and/or euro, while substantially all of our revenues are denominated in local currencies of the countries where we operate. If the Russian ruble and local currencies decline against the U.S. dollar and/or euro and price increases cannot keep pace, we could have difficulty repaying or refinancing our U.S. dollar and/or euro-denominated indebtedness, including our U.S. dollar denominated notes. At the same time, the devaluation of local currencies against the Russian ruble can adversely affect our revenues reported in Russian rubles and increase our costs in terms of local currencies. In addition, local regulatory restrictions on the purchase of hard currency in the majority of CIS countries (for example, Ukraine, Uzbekistan or Turkmenistan) may delay our ability to purchase equipment and services necessary for network expansion which, in turn, may cause difficulty in expanding our subscriber base in that countries. Further, a portion of our cash balances is held in jurisdictions outside Russia, and as a result of exchange controls in those jurisdictions, these cash balances may not always be readily available for our use.

        The Ukraine's economic crisis combined with political unrest and events in the Eastern part of Ukraine led to the weakening of the hryvnia, with it rising from 15.77 hryvnias per U.S. dollar on December 31, 2014 to 24.00 hryvnias per one U.S. dollar on December 31, 2015, reflecting capital outflow in response to the continuing political instability in Ukraine. See also "—Political and Social Risks—Political instability in Ukraine could have a material adverse effect on our operations in Ukraine and on our business, financial condition and results of operations."

        The Belarusian ruble depreciated against the U.S. dollar reaching 11,850 Belarusian rubles per one U.S. dollar on December 31, 2014, to 18,569 Belarusian rubles per one U.S. dollar on December 31, 2015. The possible devaluation of the Belarusian ruble in the future may adversely affect our revenues from this market. See also "—Inflation could increase our costs and adversely affect our results of operations," "Item 11. Quantitative and Qualitative Disclosures about Market Risk—Foreign Currency Risk."

If we are unable to obtain adequate capital, we may have to limit our operations substantially, which could have a material adverse effect on our business, financial condition, results of operations and prospects.

        We have to make significant capital expenditures, particularly in connection with the development, construction and maintenance of, and the purchasing of necessary software for our mobile and fixed line networks. We spent RUB 91,929 million in 2014 and RUB 96,111 million (excluding costs of RUB 3.382 billion related to the acquisition of a 4G license in Russia in 2015 and excluding costs of RUB 7.044 billion related to the acquisition of a 3G license in Ukraine in 2015) in 2015 for the fulfillment of our capital spending plans. In addition, the acquisition of 3G and 4G licenses and frequency allocations and the build-out of our 3G, 4G and broadband Internet networks will require additional capital expenditures. However, future financings and cash flow from our operations may not be sufficient to meet our planned needs in the event of various unanticipated potential developments, including the following:

•

a lack of external financing sources;



•

changes in the terms of existing financing arrangements;

        In 2014 and 2015 the United States and European Union announced sanctions applying to a number of Russian and Ukrainian individuals and associated institutions which were considered to have contributed to the situation in Ukraine and Crimea. The sanctions may be extended and our ability to gain external funding may be affected. See also "—Political and Social Risks—Political instability in Ukraine could have a material adverse effect on our operations in Ukraine and on our business, financial condition and results of operations," and "—A deterioration in relations between Russia and other former Soviet republics and/or the United States and the European Union could materially adversely affect our business, financial condition, results of operations and prospects and the value of our shares and ADSs."

        Our indebtedness and the limits imposed by covenants in our debt obligations could limit our ability to obtain additional financing and thereby constrain our ability to invest in our business and place us at a possible competitive disadvantage. Also, currently we are not able to raise equity financing through newly issued depositary receipts such as ADSs, due to Russian securities regulations providing that no more than 25% of a Russian company's shares may be circulated abroad through sponsored depositary receipt programs. Prior to December 31, 2005 and at the time of our initial public offering, this threshold was 40% and our current ADSs program is near its full capacity. If we cannot obtain adequate funds to satisfy our capital requirements, we may need to limit our operations significantly, which could have a material adverse effect on our business, financial condition, results of operations and prospects.

Inflation could increase our costs and adversely affect our results of operations.

        The Russian and Ukrainian economies have been characterized by high rates of inflation. According to the Federal Statistics Service, inflation reached 11.4% and 12.9% in Russia in 2014 and 2015, respectively. The inflation increase was mainly driven by depreciation of the ruble, restrictions on foreign trade and acceleration in food prices. Currently, there are high inflation expectations related to both ruble exchange rate and resources market volatility. As we tend to experience inflation-driven increases in certain of our costs, which are sensitive to rises in the general price level in Russia and Ukraine, our costs will rise. In addition, high inflation level in Russia may lead, inter alia, to higher marketing expenditures by us in order to remain competitive. In this situation, due to competitive pressures, we may not be able to raise the prices we charge for our products and services sufficiently to preserve operating margins.

        In 2015, growth of consumer prices in Ukraine reached 43.3% compared to 24.9% in 2014, according to the "Inflation Report" of the National Bank of Ukraine. Among the main reasons of significant price growth are weakening of the national currency, increase in prices for energy carriers, utility payments and additional tax burden.

        At the end of 2014 and 2015, inflation in Belarus amounted to 16.2% and 12.0%, respectively.

If Apple Sales International lodges a claim against us as a result of our failure to fulfill our iPhone handset purchase commitment, this could have a material adverse effect on our financial condition and results of operations.

        In 2008, we entered into an unconditional purchase agreement with Apple Sales International to buy certain quantities of iPhone handsets at list prices at the dates of the respective purchases for the three year period. The purchase agreement terminated on September 30, 2012. Pursuant to the agreement, we were also to incur certain iPhone promotional costs. We did not fulfill our total purchase installment contemplated by the agreement. As a result of not having fulfilled our required purchase commitments under our agreement with Apple Sales International, it is possible that Apple Sales International may bring a claim against us, which could have a material adverse effect on our financial condition and results of operations. A reasonable estimate of any potential loss with respect to the remotely possible claim cannot be made.

Indentures relating to some of our notes contain, and some of our loan agreements and Sistema's loan agreements contain, restrictive covenants, which limit our ability to incur debt and to engage in various activities.

        Covenants in the agreement relating to our Eurobonds due 2023 limit our ability to create liens on our properties, merge or consolidate with another person or convey our properties and assets to another person. Additionally, the indentures governing our U.S. dollar-denominated notes due 2020 contain covenants limiting our ability to incur debt, create liens on our properties, enter into sale and lease-back transactions, merge or consolidate with another person or convey our properties and assets to another person, as well as our ability to sell or transfer any of our or our subsidiaries' GSM licenses for the Moscow, St. Petersburg, Krasnodar and Ukraine license areas. Some of our loan agreements contain similar and other covenants, including, in relation to the incurrence of indebtedness, creation of liens and disposal of assets. We may also incur additional credit obligations providing for similar covenants. Failure to comply with these covenants may cause a default and result in the debt becoming immediately due and payable, which would materially adversely affect our business, financial condition and results of operations.

        In addition, Sistema, which owns 51.46% of our total charter capital directly and through its subsidiaries (53.46% excluding treasury shares) and consolidates our results in its financial statements, is subject to various covenants in its credit facilities. These covenants impose restrictions on Sistema and its restricted subsidiaries (including us) with respect to, inter alia, incurrence of indebtedness, creation of liens and disposal of assets. In the indentures, Sistema undertakes that it will not, and will not permit its restricted subsidiaries (including us) to, incur indebtedness unless a certain indebtedness level/EBITDA (as defined therein) ratio is met. In addition to us, Sistema has various other businesses that require capital and, therefore, the consolidated Sistema group's capacity to incur indebtedness otherwise available to us could be diverted to its other businesses. Sistema may also enter into other agreements in the future that may further restrict it and its subsidiaries (including us) from engaging in these and other activities. We expect Sistema to exercise control over us in order for Sistema, as a

consolidated group, to meet its obligations under its current and future financings and other agreements, which could materially limit our ability to obtain additional financing required for the implementation of our business strategy. The inability to implement our business strategy may have a material adverse effect on our financial condition and results of operations.

If a change in control occurs, our noteholders and other debt holders may require us to redeem notes or other debt, which could have a material adverse effect on our financial condition and results of operations.

        Under the terms of our outstanding notes, if a change in control occurs, our noteholders will have the right to require us to redeem notes not previously called for redemption. The price we will be required to pay upon such event will be 101% of the principal amount of the notes, plus interest accrued prior to the redemption date. A change in control will be deemed to have occurred in any of the following circumstances:

•

with respect to the notes due 2020, any person acquires beneficial or legal ownership of, or control over, more than 50% of our issued shares, ownership of or control over more than 50% of the voting interests in our share capital or obtains the power to elect not less than half of our directors, provided that the following transactions would not be deemed to result in a change of control:



•

any acquisition by Sistema or its subsidiaries that results in the 50% threshold being exceeded;



•

any acquisition by us, our subsidiary or our employee benefit plan; and



•

a contribution by Sistema of all or part of its ownership interest in us into a partnership, joint venture or other indirect holding vehicle as long as any other person who is an owner of or party interested in that partnership, joint venture or other indirect holding vehicle does not acquire beneficial ownership of or control over more than 50% of our issued shares, does not acquire ownership of or control over more than 50% of the voting interests in our share capital and does not obtain the power to elect not less than half of our directors.

        Some of our loan agreements contain similar change of control provisions. If a change in control occurs, and our noteholders and other debt holders exercise their right to require us to redeem all of their notes or debt, such event could have a material adverse effect on our financial condition and results of operations.

        In addition, under certain of our debt agreements, an event of default may be deemed to have occurred and/or we may be required to make a prepayment if Sistema disposes of its stake in our company and a third party takes a controlling position in our company. The occurrence of any such event of default or failure to make any required prepayment which leads to an event of default could trigger cross default/cross acceleration provisions under certain of our other debt agreements. In such event, our obligations under one or more of these agreements could become immediately due and payable, which would have a material adverse effect on our business and our shareholders' equity. If Sistema were to dispose of its stake in us, our company may be deprived of the benefits and resources that it derives from Sistema, which could harm our business.

Risks Relating to Our Countries of Operation Economic Risks

Economic instability in the countries where we operate could adversely affect our business.

        Since the dissolution of the Soviet Union in 1991, the economies of Russia and other CIS countries where we operate have experienced periods of considerable instability and have been subject to abrupt downturns. Most notably, following the Russian government's default on its ruble denominated securities in August 1998, the CBR stopped its support of the ruble and a temporary moratorium was imposed on certain hard currency payments. These actions resulted in the immediate

40

Table of Contents

and severe devaluation of the ruble and a sharp increase in the rate of inflation, a substantial decline in the prices of Russian debt and equity securities, and an inability of Russian issuers to raise funds in the international capital markets. These problems were aggravated by the subsequent near collapse of the Russian banking sector, with the termination of banking licenses of a number of major Russian banks. This crisis had a severe impact on the economies of Russia and the other CIS countries.

        The economies of Russia and the other CIS countries where we operate currently experience negative trends. In 2014 the growth of GDP in Russia was 0.7% in comparison with 1.3% in 2013 according to Federal State Statistics service. According to preliminary information published by the Federal State Statistics service, Russian GDP decreased by 3.7% in 2015.

        According to press reports in January 2016, the Ministry of Economic Development of the Russian Federation forecasted GDP shrinking by 0.8% in 2016.

        A financial downturn, as well as any future economic downturns or slowturns in Russia or the other CIS countries where we operate could lead to decreased demand for our services, decreased revenues and negatively affect our liquidity and ability to obtain debt financing, which would have a material adverse effect on our business, financial condition, results of operations and prospects.

The Russian banking system remains underdeveloped, the number of creditworthy banks in Russia is limited and another banking crisis could place severe liquidity constraints on our business.

        Russia's banking and other financial systems are less developed or regulated as compared to other countries, and Russian legislation relating to banks and bank accounts is subject to varying interpretations and inconsistent application. The August 1998 financial crisis resulted in the bankruptcy and liquidation of many Russian banks and almost entirely eliminated the developing market for commercial bank loans at that time. Many Russian banks currently do not meet international banking standards, and the transparency of the Russian banking sector in some respects still lags far behind internationally accepted norms. Aided by inadequate supervision by the regulators, certain banks do not follow existing CBR regulations with respect to lending criteria, credit quality, loan loss reserves or diversification of exposure. Furthermore, in Russia, bank deposits made by corporate entities generally are not insured.

        In recent years, there has been a rapid increase in lending by Russian banks, which has been accompanied by a deterioration in the credit quality of the borrowers. In addition, a robust domestic corporate debt market is leading Russian banks (including the banks with which we conduct banking transactions) to hold increasingly large amounts of Russian corporate ruble bonds in their portfolios, which is further deteriorating the risk profile of Russian bank assets. The serious deficiencies in the Russian banking sector, combined with the deterioration in the credit portfolios of Russian banks, may result in the banking sector being more susceptible to market downturns or economic slowdowns, including due to Russian corporate defaults that may occur during any such market downturn or economic slowdown. In addition, the CBR has from time to time revoked the licenses of certain Russian banks, which resulted in market rumors about additional bank closures and many depositors withdrawing their savings. Recently a number of banks and credit institutions have lost their licenses due to deficiency of capital and failure to meet the CBR requirements. During a banking crisis, Russian companies may be subject to severe liquidity constraints due to the limited supply of domestic savings and the withdrawal of foreign funding sources that may occur during such a crisis.

        The recent disruptions in the global markets have generally led to reduced liquidity and increased cost of funding in Russia. Borrowers have generally experienced a reduction in available financing both in the inter-bank and short-term funding market, as well as in the longer term capital markets and bank finance instruments. The non-availability of funding to the banking sector in the Russian Federation has also negatively affected the anticipated growth rate of the Russian Federation. During the course of 2014 and the first quarter of 2015, the credit rating of the Russian Federation was placed

41

Table of Contents

for review and downgraded by each of Moody's, Fitch Ratings and Standard & Poor's several times. As of April 1, 2016, Russia has a Ba1 sovereign credit rating under review for downgrade from Moody's compared to Baa1 with a stable outlook as at January 1, 2014, BBB– long-term sovereign rating with a negative outlook from Fitch Ratings compared to BBB with a stable outlook as at January 1, 2014 and BB+/B foreign currency sovereign credit rating with negative outlook from Standard & Poor's as compared to BBB/A-2 with stable outlook as at January 1, 2014. See also "—Political and Social Risks—Political instability in Ukraine could have a material adverse effect on our operations in Ukraine and on our business, financial condition and results of operations."

        The Russian government and the CBR provide financial support only to a limited number of banks, which may result in the liquidation of other banks and financial institutions. In 2014 and 2015, the CBR revoked the licenses of a number of Russian banks for reasons associated with implementing high-risk lending policies, loss of liquidity and non-compliance with anti-money laundering legislation. A combination of these factors may result in a significant deterioration in the financial fundamentals of Russian banks, notably liquidity, asset quality and profitability.

        There is currently a limited number of sufficiently creditworthy Russian banks and few ruble-denominated financial instruments in which we can invest our excess ruble cash. We hold the bulk of our excess ruble and foreign currency cash in Russian banks, including subsidiaries of foreign banks. Another banking crisis or the bankruptcy or insolvency of the banks from which we receive or with which we hold our funds could result in the loss of our deposits or affect our ability to complete banking transactions in Russia, which could have a material adverse effect on our business, financial condition and results of operations.

The physical infrastructure in Russia, Ukraine and the other countries where we operate is in poor condition, which could disrupt our normal business activities and adversely impact our results.

        The physical infrastructure in Russia, Ukraine and the other countries where we operate largely dates back to Soviet times and has not been adequately funded and maintained over the past two decades. Particularly affected are the rail and road networks, power generation and transmission systems, communication systems and building stock. For example, in August 2009, a major accident occurred at Russia's largest power plant, the Sayano-Shushenskaya hydroelectric power station, resulting in flooding of the engine and turbine rooms, a transformer explosion and the death of 75 people. Power generation from the station ceased completely following the incident, which led to a major power outage in the nearby residential areas and at certain industrial facilities as well as pollution of the rivers and soil as a result of an oil spill from the transformer.

        In addition, the road conditions throughout our countries of operation are poor with many roads not meeting minimum quality standards, causing disruptions and delays in the transportation of goods to and within these countries. The Russian and Ukrainian governments are actively considering plans to reorganize their national rail, electricity and communications systems. Any such reorganization may result in increased charges and tariffs while failing to generate the anticipated capital investment needed to repair, maintain and improve these systems. The deterioration of the physical infrastructure in Russia, Ukraine and the other countries where we operate harms the national economies, adds costs to doing business in these countries and generally disrupts normal business activities. These difficulties can impact us directly; for example, we keep portable electrical generators to help us maintain base station operations in the event of power outages. Further deterioration of the physical infrastructure in Russia and Ukraine, as well as the other countries where we operate, could have a material adverse effect on our business, financial condition and results of operations. In addition, the increased charges and tariffs that may result from the government reorganization may also have a material adverse effect on our business, financial condition and results of operations.

Fluctuations in the global economy may materially adversely affect the economies of the countries where we operate and our business in these countries.

        The economies of the countries where we operate are vulnerable to market downturns and economic slowdowns elsewhere in the world. As has happened in the past, financial problems or an increase in the perceived risks associated with investing in emerging economies could dampen foreign investment in Russia, Ukraine and elsewhere in the CIS, and businesses in these countries could face severe liquidity constraints, further adversely affecting their economies. Additionally, because Russia and Turkmenistan produce and export large amounts of oil and gas, the Russian and Turkmen economies are especially vulnerable to the price of oil and gas on the world market and a decline in the price of oil and gas could slow or disrupt the Russian and Turkmen economies. Recent military conflicts and international terrorist activity have also significantly impacted oil and gas prices, and pose additional risks to the Russian economy. Russia and Ukraine are also major producers and exporters of metal products and their economies are vulnerable to world commodity prices and the imposition of tariffs and/or antidumping measures by the United States, the European Union or by other principal export markets.

        The disruptions recently experienced in the international and domestic capital markets have led to reduced liquidity and increased credit risk premiums for certain market participants and have resulted in a reduction of available financing. Companies located in emerging markets, including us, may be particularly susceptible to these disruptions and reductions in the availability of credit or increases in financing costs. To the extent that the current market downturn continues or worsens, it may lead to constraints on our liquidity and ability to obtain debt financing, which may have a material adverse effect on our business, financial conditions and results of operations.

Political and Social Risks

Political and governmental instability in Russia and other countries of our operations could materially adversely affect our business, financial condition, results of operations and prospects and the value of our shares and ADSs.

        Since 1991, Russia has sought to transform from a one-party state with a centrally planned economy to a democracy with a market economy. As a result of the sweeping nature of the reforms, and the failure of some of them, the Russian political system remains vulnerable to popular dissatisfaction, including dissatisfaction with the results of privatizations in the 1990s, as well as to demands for autonomy from particular regional and ethnic groups. Furthermore, parliamentary elections held in December 2011 and presidential elections held in March 2012 led to some political demonstrations in a few Russian cities. Other countries where we operate may pose similar challenges. For example, mass protests and armed conflicts in Ukraine from November 2013 as well as the referendum in Crimea in favor of joining the Russian Federation and consequent developments in the region contribute to political tension and uncertainty in Ukraine, see also "—Political instability in Ukraine could have a material adverse effect on our operations in Ukraine and on our business, financial condition and results of operations." Current and future changes in the Russian and other CIS governments, major policy shifts or lack of consensus between various branches of the government and powerful economic groups could disrupt or reverse economic and regulatory reforms. Any disruption or reversal of reform policies could lead to political or governmental instability or the occurrence of conflicts among powerful economic groups, which could have a material adverse effect on our business, financial condition, results of operations and prospects and the value of our shares and ADSs. A deterioration of the socio-political situation in Russia could also trigger an event of default under some of our loan agreements.

Potential conflict between central and regional authorities could create an uncertain operating environment hindering our long-term planning ability.

        The Russian Federation is a federation of sub-federal political units, consisting of republics, territories, regions, cities of federal importance and autonomous regions and districts. The delineation of authority and jurisdiction among the members of the Russian Federation and the federal government is, in many instances, unclear and remains contested. Lack of consensus between the federal government and local or regional authorities could result in the enactment of conflicting legislation at various levels and may lead to political instability. In particular, conflicting laws have been enacted in the areas of privatization, land legislation and licensing. Some of these laws and governmental and administrative decisions implementing them, as well as certain transactions consummated pursuant to them, have in the past been challenged in the courts, and such challenges may occur in the future. This lack of consensus may hinder our long-term planning efforts and create uncertainties in our operating environment, both of which may prevent us from effectively and efficiently implementing our business strategy.

        Additionally, ethnic, religious, historical and other divisions have, on occasion, given rise to tensions and, in certain cases, military conflict, which can halt normal economic activity and disrupt the economies of neighboring regions. For example, violence and attacks relating to the Chechen conflict have spread to other parts of Russia and several terrorist attacks have been carried out in other parts of Russia, including Moscow. The further intensification of violence, including terrorist attacks and suicide bombings, or its spread to other parts of Russia, could have significant political consequences, including the imposition of a state of emergency in some or all of Russia. Moreover, any terrorist attacks and the resulting heightened security measures are likely to cause disruptions to domestic commerce and exports from Russia. These factors could materially adversely affect our business and the value of our shares and ADSs.

        In Ukraine, tensions between certain regional authorities and the central government were ignited following the November 2004 presidential elections. Amid the mass demonstrations and strikes that took place throughout Ukraine to protest the election process and results, the conference of the representatives of the regional authorities in eastern Ukraine decided to conduct a referendum on creating an autonomous region, separate from Ukraine. Later the regional authorities ultimately backed down from this intention, and tensions in Ukraine subsided. The tensions in eastern Ukraine also took place in April 2014 due to political instability. See "—Political instability in Ukraine could have a material adverse effect on our operations in Ukraine and on our business, financial condition and results of operations."

A deterioration in relations between Russia and other former Soviet republics and/or the United States and the European Union could materially adversely affect our business, financial condition, results of operations and prospects and the value of our shares and ADSs.

        Relations between Russia and certain other former Soviet republics are or have in the past been strained. For example, in August 2008, an armed conflict erupted between Russia and Georgia over the self-appointed republics South Ossetia and Abkhazia, culminating in Russia's recognition of their independence from Georgia. The political and economic relationships between Ukraine and Russia have also been strained in recent years, culminating in the current geopolitical crisis with respect to Crimea.

        See also "—Political instability in Ukraine could have a material adverse effect on our operations in Ukraine and on our business, financial condition and results of operations," and "—Risks Relating to our Financial Condition—Changes in the exchange rate of local currencies in the countries where we operate against the Russian ruble could adversely impact our revenues reported in Russian rubles as

well as changes in the exchange rate of the Russian ruble and local currencies against the U.S. dollar and/or euro could adversely impact our costs in terms of the Russian ruble and local currencies."

        The conflicts between Russia and other former Soviet republics have, in some instances, also strained Russia's relationship with the United States and the European Union which, at times, has negatively impacted Russia's financial markets. For example, during 2014, a number of Russian, Ukrainian and Crimean governmental officials and individuals (including representatives of the Russian Parliament), several Russian businessmen and a Russian bank were designated as "Specially Designated Persons" by the U.S. Department of the Treasury, Office of Foreign Assets Control ("OFAC") pursuant to three executive orders signed by the President of the United States. The first and second executive orders (Nos. 13660 and 13661) targeted former Ukrainian officials and current Russian Federation officials, as well as persons who operate in the arms or related sectors in the Russian Federation. The third executive order (No. 13662) significantly expanded the scope of the prior two executive orders by providing OFAC the authority to block the property of designated persons who operate in certain sectors of Russia's economy, including financial services, energy, metals and mining, engineering, defense and related sectors, although no such persons have been designated as a Specially Designated Person pursuant to this third, and much more expansive, order. OFAC further introduced new "sectoral sanctions" against certain Russian economic sectors as potential targets for sanctions in executive order No. 13662. The companies targeted by these sectoral sanctions operate within the financial services and energy sectors of the Russian economy and are included by OFAC to the Sectoral Sanctions Identifications ("SSI") List. These sectoral sanctions prohibit U.S. persons, or other persons within the United States, from transacting in, providing financing for, or otherwise dealing in debt of longer than 90 days maturity and equity for the sanctioned banks and debt of longer than 90 days maturity for the sanctioned energy companies, in each case issued after the date of the relevant OFAC directive, including entities owned 50 per cent or more by these entities. Hence, the restrictions applicable to entities that are on the SSI List differ from the consequences of being included in the "Specially Designated Persons" List and their property and assets are not subject to blocking by U.S. persons. In addition to the sectoral sanctions, OFAC added further individuals and certain entities, including a Russian shipbuilding company and state defense firms, to the "Specially Designated Persons" List in July 2014 and five more state defense firms in September 2014 and also expanded its SSI List. In relation to state owned technology company and the banks included in the SSI List, in September 2014, OFAC lowered the debt maturity threshold to 30 days. Furthermore, OFAC prohibited the exportation of goods, services (except for financial services), or technology in support of exploration or production for deepwater, Arctic offshore or shale projects to five Russian energy companies. In December 2014, the U.S. President signed into law a bill passed by the U.S. Congress which will extensively widen the breadth of U.S. sanctions against Russian entities and persons. To maintain the efficacy of existing sanctions OFAC made further designation in 2015, expanding the SDN List and SSI List with further individuals, Russian and Crimean entities.

        The Council of the European Union has introduced its own list of persons that are subject to EU sanctions, as well as sanctions that target certain sectors of the Russian economy. In July 2014, the EU enacted Council Regulation (EU) No. 833/2014, that was amended in September 2014, that limits access to the EU capital markets for Russian state-owned financial institutions, imposes an embargo on trade in arms, establishes an export ban for dual use goods for military end users, and curtail Russian access to sensitive technologies particularly in the field of the oil sector.

        The governments of the U.S. and certain European Union member states, as well as certain EU officials have indicated that they may consider additional sanctions should the armed conflict in Ukraine continue or escalate. On February 16, 2015, the EU expanded the list of sanctioned persons by including, among others, several Russian state deputies and government officials. These sanctions were reviewed by the Council of the EU in December 2015 and remain in force until July 31, 2016, unless they are renewed or revoked at an earlier date.

        The Ukrainian Cabinet of Ministers initiated adoption of the Law "On Sanctions" by the Verkhovna Rada of Ukraine which came into force on September 12, 2014. The law provides for special economic and other restrictive measures (sanctions) against foreign states, foreign legal entities and individuals involved in activities threatening the national security, sovereignty and territorial integrity of Ukraine and the rights and freedoms of its citizens. The law stipulates 25 types of sanctions which include, among others:

•

asset freezing;



•

temporary limitation of a right to use or dispose of property;



•

cancellation or suspension of licenses and other permits, including special permits for subsoil use;



•

prohibition to use radio frequency resources in Ukraine; and



•

termination or suspension of rendering telecommunication services or utilizing telecommunications networks of general use.

        A draft law expanding the list of sanctions, stipulated by the Law "On sanctions" was introduced on July 13, 2015. It includes, inter alia, seizure of the objects of the Russian proprietary rights as well as objects of private property of its residents in case of social necessity for the state's benefit.

        In addition, the Presidential Decree No. 549/2015 dated September 16, 2015 approved the decision of the National Security and Defense Council of Ukraine as of September 2, 2015 "On application of personal special economic and other restrictive measures (sanctions)." The list of individuals and legal entities to which sanctions are applied for a one-year term has been specified. MTS Ukraine has not been included into the list.

        Pursuant to the Law of Ukraine "On the legal status of martial law" dated June 8, 2015, military command together with military administrations are permitted to temporarily limit rights, freedoms and legal interests of individuals and legal entities within specific territories where martial law is introduced.

        On June 28, 2015, amendments to the Law of Ukraine "On licensing of certain types of economic activity" came into force expanding the terms of license cancellation, including adoption of an "act on documentary proof of control over licensee actions by other states, carrying out armed aggression against Ukraine or whose actions create preconditions either for military conflict or use of military force against Ukraine." Furthermore, a draft law "On Electronic Communication" contains similar grounds for license cancellation as those set in the Law "On licensing of certain types of economic activity." See also "—Risks Relating to Our Business—Governmental regulation of SMP operators in Ukraine could adversely affect our results of operations."

        It is currently unclear how the measures might refer to MTS Ukraine but this may substantially adversely affect our business, financial condition and results of operations.

        There is still significant uncertainty regarding the extent or timing of any further political or economic sanctions, or the ultimate impact of the Ukrainian crisis on Russia's relationship with Ukraine, the United States or the European Union. Any further sanctions may have a negative effect on the Russian economy, the financial condition of our partners and suppliers, our ability to conduct trade and financial transactions, our ability to obtain financing on commercially reasonable terms, and the level and volatility of the trading price of our shares and ADSs. Any of the foregoing circumstances could have a material adverse effect on our business, financial condition, results of operations and prospects and the value of our shares and ADSs.

Political instability in Ukraine could have a material adverse effect on our operations in Ukraine and on our business, financial condition and results of operations.

        Economic crisis, deterioration of key aspects of the economy and the lack of investment into the social infrastructure, has, amongst other things, led to the instability of the political situation in Ukraine where we have significant operations. Furthermore, the refusal of the Ukrainian Government to enter into an association agreement with the European Union in November 2013, incited mass protests in Kiev and other regions of the country. These protests caused, amongst other things, a downgrade of Ukraine's international ratings and significant depreciation of the national currency, see "—Risks Relating to our Financial Condition—Changes in the exchange rate of local currencies in the countries where we operate against the Russian ruble could adversely impact our revenues reported in Russian rubles as well as changes in the exchange rate of the Russian ruble and local currencies against the U.S. dollar and/or euro could adversely impact our costs in terms of the Russian ruble and local currencies."

        On March 16, 2014, a referendum in favor of joining the Russian Federation was held in Crimea with the consequent declaration of independence from Ukraine and accession to the Russian Federation by the parliament of Crimea.

        The armed conflict in Eastern Ukraine that has taken place since April 2014 has destabilized the region and caused uncertainty in our operation in the region of the armed conflict. It has also led to damage of our network equipment in the region followed by related losses. Should the economic and political situation in Eastern Ukraine become further destabilized, should local operators enter the market or other external factors affect the region, this may adversely affect our business, financial condition, corporate image and results of operations as well as cause regulatory uncertainties.

        These events have resulted in heightened tensions between Ukraine and the Russian Federation and have strained relationships of the Russian Federation with the United States and the European Union, which may adversely impact our business. Furthermore, should tensions between the Russian Federation and Ukraine continue or increase, or should the economic and political situation in Ukraine become further destabilized, our business interests in Ukraine and other impacted regions may be adversely affected or targeted. The continued impact of these events and any continuing or escalating military action, public protests, unrest, political instability or further sanctions could have a further adverse effect on our business in Ukraine, our financial condition and reputation.

Crime and corruption could disrupt our ability to conduct our business and thus materially adversely affect our operations.

        The political and economic changes in recent years in the countries where we operate have resulted in significant dislocations of authority. The local and international press have reported the existence of significant organized criminal activity, particularly in large metropolitan centers. Property crime in large cities has increased substantially. In addition, the local and international press have reported high levels of corruption, including the bribing of officials for the purpose of initiating investigations by government agencies. Press reports have also described instances in which government officials engaged in selective investigations and prosecutions to further the commercial interests of

certain government officials or certain companies or individuals. Additionally, some members of the media in the countries we operate in regularly publish disparaging articles in return for payment. The depredations of organized or other crime, demands of corrupt officials or claims that we have been involved in official corruption could result in negative publicity, disrupt our ability to conduct our business and could thus materially adversely affect our business, financial condition, results of operations and prospects.

Social instability could increase support for renewed centralized authority, nationalism or violence and thus materially adversely affect our operations.

        A decrease in the price of oil, as well as increased unemployment rates, the failure of the government and many private enterprises to pay full salaries on a regular basis and the failure of salaries and benefits generally to keep pace with the rapidly increasing cost of living have led in the past, and could lead in the future, to labor and social unrest. Labor and social unrest may have political, social and economic consequences, such as increased support for a renewal of centralized authority; increased nationalism, including restrictions on foreign involvement in the economies of the countries where we have operations; and increased violence. An occurrence of any of the foregoing events could restrict our operations and lead to the loss of revenues, materially adversely affecting our operations. See also "—Political instability in Ukraine could have a material adverse effect on our operations in Ukraine and on our business, financial condition and results of operations."

Legal Risks and Uncertainties

Weaknesses relating to the legal system and legislation in the countries where we operate create an uncertain environment for investment and business activity, which could have a material adverse effect on the value of our shares and ADSs.

        Each of the countries we operate in is still developing the legal framework required to support the market economy. The following risk factors relating to these legal systems create uncertainties with respect to the legal and business decisions that we make, many of which do not exist in countries with more developed market economies:

•

inconsistencies between and among the constitution, federal and regional laws and subordinate legislation (presidential decrees and governmental, ministerial and local orders, decisions and resolutions) and other acts;



•

the lack of judicial and administrative guidance on interpreting certain legislation as well as conflicting interpretations of supreme general jurisdiction and arbitrazh courts;



•

the relative inexperience of judges and courts in interpreting certain aspects of legislation;



•

the lack of an independent judiciary;



•

a high degree of discretion on the part of governmental authorities, which could result in arbitrary actions such as suspension or termination of our licenses; and



•

poorly developed bankruptcy and liquidation procedures and court practice that create possibilities of abuse.

        The recent nature of much of the legislation in the CIS countries, the lack of consensus about the scope, content and pace of economic and political reform and the rapid evolution of these legal systems in ways that may not always coincide with market developments place the enforceability and underlying constitutionality of laws in doubt and result in ambiguities, inconsistencies and anomalies. In addition, legislation in these countries often contemplates implementing regulations that have not yet been promulgated, leaving substantial gaps in the regulatory infrastructure. All of these weaknesses could affect our ability to enforce our rights under our licenses and contracts, or to defend ourselves against

claims by others. Moreover, it is possible that regulators, judicial authorities or third parties may challenge our internal procedures and bylaws, as well as our compliance with applicable laws, decrees and regulations.

The inability of our subsidiaries in the countries in which we are present to maintain control over their operations and assets may adversely affect our business, financial condition and results of operations.

        If we are unable to protect our business entities in the countries in which we operate from the withdrawal or suspension or regulatory scrutiny, this may adversely affect our business, financial condition and results of operations. For example, in June 2012, the authorities of the Republic of Uzbekistan began audits of the financial and operating activities of MTS' wholly-owned subsidiary Uzdunrobita. Further various claims for violation of tax, antimonopoly and industry legislation were made against Uzdunrobita, which resulted in significant amounts of fines and penalties, revocation of all licenses and suspension of services. Total amount of damages was calculated and determined on the basis of all the aforementioned claims against Uzdunrobita and amounted to approximately RUB 18,375 million payable in equal installments over eight months.

        Uzdunrobita paid two scheduled installments in November and December 2012 totaling approximately RUB 4,583.4 million. On January 14, 2013, further to its partial payment of the third installment due in January 2013 totaling approximately RUB 481 million and constituting the remaining amount of cash held in its bank accounts, Uzdunrobita filed a petition for voluntary bankruptcy to the Tashkent Economic Court on the grounds of its inability to meet further obligations.

        On April 22, 2013, the Tashkent Economic Court declared Uzdunrobita bankrupt and initiated a liquidation process. Uzdunrobita was later liquidated. In 2012, we filed a claim against the Republic of Uzbekistan in the International Center for Settlement of Investment Disputes ("ICSID"), part of the World Bank Group, in Washington, D.C.

        On July 31, 2014, we and the Republic of Uzbekistan signed a settlement agreement (the "Settlement Agreement") and MTS agreed to reenter the Uzbekistan market through a joint enterprise with MTS holding a 50.01% in the charter capital of the joint enterprise, while the remaining 49.99% belongs to a state-owned unitary enterprise established and managed by the State Committee for Communications, Development of Information Systems and Telecommunications Technologies of the Republic of Uzbekistan. The Settlement Agreement is governed by English law and provides for resolution of any disputes arising out of the Settlement Agreement in the International Court of Arbitration under International Chamber of Commerce in Paris (ICC).

        On September 24, 2014, in accordance with the Settlement Agreement, the authorities of the Republic of Uzbekistan granted the joint enterprise 2G, 3G and LTE licenses, provided necessary frequencies and numbering capacity, fostered entrance into lease agreements for communication channels and issued all permissions required to the joint enterprise so it could operate and offer full telecommunications services throughout Uzbekistan. The joint enterprise has also received guaranties for investment protection and return of investments in accordance with the laws of the Republic of Uzbekistan.

        On November 2014, ICSID has discontinued international arbitration proceedings between MTS and the Republic of Uzbekistan following the submission of a joint application by both parties.

        On December 1, 2014, the joint enterprise, named UMS, launched sales of SIM cards through its proprietary network of 20 stores and through another 230 independent locations throughout Uzbekistan and started provision of 2G/3G telecommunication services on the entire territory of Uzbekistan.

and ADSs" and "—Political instability in Ukraine could have a material adverse effect on our operations in Ukraine and on our business, financial condition and results of operations."

The inability of MTS-Turkmenistan to sustain its operations in Turkmenistan on commercially acceptable terms or at all may adversely affect our business, financial condition and results of operations.

        In December 2010, the Group suspended its operations in Turkmenistan following notification by the Ministry of Communications of Turkmenistan of a decision to suspend licenses held by BCTI, the Group's wholly-owned subsidiary in Turkmenistan, for a period of one month starting from December 21, 2010. On January 21, 2011, the period of license suspension expired, however, permission to resume operations was not granted.

        The Group operated in Turkmenistan under a trilateral agreement signed in November 2005 by BCTI, MTS and the Ministry of Communications of Turkmenistan valid for a period of five years with a possibility to extend its term. In accordance with certain provisions of this agreement, BCTI shared net profits derived from its operations in the country with the Ministry of Communications of Turkmenistan.

        Following the decision to suspend BCTI's licenses, Turkmenistan government authorities took further steps, including unilateral termination of interconnect agreements between BCTI and state-owned telecom operators, to prevent the Group from providing services to its customers.

        On May 24, 2012 we concluded an agreement with the state-owned telecom operator Turkmentelekom relating to our terms of operations in Turkmenistan which resulted from negotiations between the Turkmenistan government and ministries. The agreement has a five year term and can be extended for next five years provided certain terms and conditions are satisfied. Under this agreement we are obliged to pay Turkmentelekom a monthly amount calculated as 30% of our net profit in Turkmenistan based on accounting rules of Turkmenistan.

        On July 25, 2012, we, our subsidiary BCTI, the republic of Turkmenistan, the Ministry of Communications of Turkmenistan, the state-owned company Turkmentelecom and mobile operator Altyn Asyr signed a settlement agreement (including the dismissal of all international lawsuits) concerning the suspension of our operations in Turkmenistan in December 2010.

        In August 2012, we restarted our mobile communication network in Turkmenistan and resumed providing services to subscribers who had not canceled their contracts. Since October 1, 2012 we resumed our operations in Turkmenistan entirely and started entering into contracts with new subscribers.

Russian and Ukrainian companies can be forced into liquidation on the basis of formal non-compliance with certain legal requirements.

        Certain provisions of Russian law may allow government authorities to seek a court order for the liquidation of a Russian legal entity on the basis of its formal non-compliance with certain requirements during formation, reorganization or during its operation.

        For example, under Russian corporate law, if the net assets of a Russian joint stock company calculated on the basis of Russian accounting standards are lower than its charter capital as at the end of its third or any subsequent financial year, the company must either decrease its charter capital or be placed in liquidation. If the company fails to comply with these requirements, governmental or local authorities can seek the involuntary liquidation of such company in court, and the company's creditors will have the right to accelerate their claims or demand early performance of the company's obligations as well as demand compensation of any damages.

        The existence of negative assets may not accurately reflect the actual ability to pay debts as they fall due. Many Russian companies have negative net assets due to very low historical asset values reflected on their Russian accounting standards balance sheets; however, their solvency, i.e., their ability to pay debts as they fall due, is not otherwise adversely affected by such negative net assets. Some Russian courts, in deciding whether or not to order the liquidation of a company for having negative net assets, have looked beyond the fact that the company failed to fully comply with all applicable legal requirements and have taken into account other factors, such as the financial standing of the company and its ability to meet its tax obligations, as well as the economic and social consequences of its liquidation. Nonetheless, creditors have the right to accelerate claims, and file damages claims, and governmental or local authorities may seek the liquidation of a company with negative net assets. Courts have, on rare occasions, ordered the involuntary liquidation of a company for having net assets less than the minimum charter capital required by law, even if the company had continued to fulfill its obligations and had net assets in excess of the minimum charter capital at the time of liquidation.

        The amount of net assets in accordance with the local accounting standards of some of our subsidiaries is negative. Although these subsidiaries continue to meet all of their obligations to creditors, there is a minimal risk of their liquidation while the net assets remain below the minimum legal requirements.

        There have also been cases in the past in which formal deficiencies in the establishment process of a Russian legal entity or non-compliance with provisions of Russian law have been used as a basis to seek the liquidation of a legal entity. Weaknesses in the Russian legal system create an uncertain legal environment, which makes the decisions of a Russian court or a governmental authority difficult, if not impossible, to predict. If involuntary liquidation were to occur, such liquidation could lead to significant negative consequences for our group. Ukrainian law also contains provisions similar to Russian law, whereby a company's failure to comply with certain legal requirements concerning its formation, net assets or operation may be grounds for its liquidation.

Insufficient adherence to the independence and competitiveness of the judicial process, the difficulty of enforcing court decisions and governmental discretion in enforcing claims could prevent us or holders of our securities from obtaining effective redress in a court proceeding.

        The judicial bodies in the countries where we operate are not always completely independent or immune from economic and political influences, and are often understaffed and underfunded. Judges and courts are often inexperienced in the area of business, corporate and industry (telecommunications) law. Judicial precedents generally have no binding effect on subsequent decisions, and not all court decisions are readily available to the public or organized in a manner that facilitates understanding. The judicial systems in these countries can also be slow or unjustifiably swift. Enforcement of court orders can, in practice, be very difficult to achieve. All of these factors make judicial decisions in these countries difficult to predict and effective redress uncertain. Additionally, court claims are often used in furtherance of political and commercial aims or infighting. We may be subject to such claims and may not be able to receive a fair hearing. Additionally, court orders are not always enforced or followed by law enforcement agencies. Furthermore, recognition and enforcement of arbitral awards in countries where we operate is subject to compliance with corresponding rules of civil procedure and applicable laws, and courts in the countries where we operate may interpret applicable regulations in a manner which would result in denial of such recognition and enforcement.

        These uncertainties also extend to property rights. For example, during Russia and Ukraine's transformation from centrally planned economies to market economies, legislation has been enacted in both countries to protect private property against uncompensated expropriation and nationalization. However, there is a risk that due to the lack of experience in enforcing these provisions and due to political factors, these protections would not be enforced in the event of an attempted expropriation or nationalization. Expropriation or nationalization of any of our entities, their assets or portions thereof,

potentially without adequate compensation, would have a material adverse effect on our business, financial condition, results of operations and prospects.

Selective or arbitrary government action could have a material adverse effect on our business, financial condition, results of operations and prospects.

        Governmental authorities in the countries where we operate have a high degree of discretion and, at times, act selectively or arbitrarily, without hearing or prior notice, and sometimes in a manner that is inconsistent with legislation or influenced by political or commercial considerations.

        Selective or arbitrary governmental actions have reportedly included the denial or withdrawal of licenses, sudden and unexpected tax audits and claims, criminal prosecutions and civil actions. Federal and local government entities have also used ordinary defects in matters surrounding share issuances and registration as pretexts for court claims and other demands to invalidate such issuances and registrations or to void transactions. Moreover, the government also has the power in certain circumstances, by regulation or government acts, to interfere with the performance of, nullify or terminate contracts. Standard & Poor's previously expressed concerns that "Russian companies and their investors can be subjected to government pressure through selective implementation of regulations and legislation that is either politically motivated or triggered by competing business groups." In this environment, our competitors may receive preferential treatment from the government, potentially giving them a competitive advantage over us.

        In Turkmenistan, we commenced operations in June 2005 through our wholly owned subsidiary, BCTI, and operated under a trilateral agreement by and among the Ministry of Communication of Turkmenistan, BCTI and us. However, when this agreement expired on December 21, 2010, the Ministry of Communication of Turkmenistan refused to prolong the agreement. After several international lawsuits and negotiations regarding adjustments of disputes we restarted our network in Turkmenistan on August 30, 2012 and resumed our operations on October 1, 2012. Similar actions in other countries where we operate could have a material adverse effect on results of our operations. See also "—The inability of MTS-Turkmenistan to sustain its operations in Turkmenistan on commercially acceptable terms or at all may adversely affect our business, financial condition and results of operations," and "—The inability of our subsidiaries in the countries in which we are present to maintain control over their operations and assets may adversely affect our business, financial condition and results of operations."

        In addition, the Russian tax authorities have aggressively brought tax evasion claims relating to Russian companies' use of tax-optimization schemes, and press reports have speculated that these enforcement actions have been selective. Selective or arbitrary government action, if directed at us, could have a material adverse effect on our business, financial condition, results of operations and prospects.

Failure to comply with existing laws and regulations or to obtain all approvals, authorizations and permits required to transmit television channels or operate telecommunications equipment, or the findings of government inspections or increased governmental regulation of our operations, could result in a disruption in our business and substantial additional compliance costs and sanctions.

        Our operations and properties are subject to regulation by various government entities and agencies in connection with obtaining and renewing various licenses, approvals, authorizations and permits, as well as with ongoing compliance with existing laws, regulations and standards. Regulatory authorities exercise considerable discretion in matters of enforcement and interpretation of applicable laws, regulations and standards, the issuance and renewal of licenses, approvals, authorizations and permits and in monitoring licensees' compliance with the terms thereof. Russian authorities have the right to, and frequently do, conduct periodic inspections of our operations and properties throughout

52

the year. Any such future inspections may conclude that we or our subsidiaries have violated laws, decrees or regulations, and we may be unable to refute such conclusions or remedy the violations. See also "—The regulatory environment for telecommunications in Russia, Ukraine and other countries where we operate or may operate in the future is uncertain and subject to political influence or manipulation, which may result in negative and arbitrary regulatory and other decisions against us on the basis of other than legal considerations and in preferential treatment for our competitors."

        Primarily due to delays in the issuance of permits, approvals and authorizations by regulatory authorities, it is frequently not possible to procure all of the permits for each of our base stations or other aspects of our network before we put the base stations into commercial operation or to amend or maintain all of the permits when we make changes to the location or technical specifications of our base stations. At times, there can be a significant number of base stations or other communications facilities and other aspects of our networks for which we do not have final permits to operate and there can be delays in obtaining the final permits, approvals and authorizations for particular base stations or other communications facilities and other aspects of our networks.

        In addition, we may be unable to transmit certain television channels if entities that provide television content to us do not possess the requisite licenses. In case such providers of television content do not obtain the required licenses, or have their existing licenses suspended or terminated, our selection of potential television channels for transmission could be significantly limited. The Federal Law No. 257 "On Amending Federal Law "On Mass Media" and Federal Law "On Communications" dated July 13, 2015 introduced a number of amendments to the national mandatory free television channels list. In case the corresponding executive orders are adopted, the inability of operators to comply with the requirements on sequence of channels, image quality and signal reception points of national mandatory free television channels may lead to suspension or termination of a license. Furthermore, we could be subject to fines and other penalties, including forced suspension of our cable network operators' activity for up to 90 days. In some cases of our service provision (for example, those employing GPON technology) power failures in subscribers' households may lead to non-compliance with rules regulating local telephony communication services. Any of these consequences could have a material adverse effect on our business, financial condition and results of operations.

        Our failure to comply with existing laws and regulations of the countries where we operate or to obtain all approvals, authorizations and permits required to operate telecommunications equipment, or the findings of government inspections including the State Labor Inspection Service may also result in the imposition of fines or penalties or more severe sanctions including the suspension, amendment or termination of our licenses, approvals, authorizations and permits, or in requirements that we cease certain of our business activities, or in criminal and administrative penalties applicable to our officers. Moreover, an agreement or transaction entered into in violation of law may be invalidated and/or unwound by a court decision. Any such decisions, requirements or sanctions, or any increase in governmental regulation of our operations, could result in a disruption of our business and substantial additional compliance costs and could materially adversely affect our business, financial condition, results of operations and prospects. In addition, we may assume risks of potential claims from subscribers and regulating authorities regarding former activities of the acquired or merged businesses.

        Generally, communication networks are vulnerable to physical or software break-ins, viruses, unauthorized interferences and similar events. Should such events occur with respect to our network elements, we may become subject for additional inspection by the regulatory authorities. Although we obtain all necessary permissions and certificates for the operation of our equipment and provide measures to protect confidential information, our failure to fully comply with all legislation requirements could result in the imposition of fines or penalties, additional government regulations, substantial additional compliance costs, disruption of our business including its suspension or termination, and other adverse effects.

        In 2014, NCCIR conducted two unplanned inspections with respect to MTS Ukraine. The inspections resulted in the issuance of orders, one of which was disputed by MTS Ukraine in court proceedings. The Court of Appeal Instance made a decision in favor of MTS Ukraine and cancelled the NCCIR order, however, NCCIR appealed the case to the High Administrative Court of Ukraine. After having considered the cassation petition filed by NCCIR, the High Administrative Court of Ukraine upheld the decision of the first instance court. The claim of MTS Ukraine was fully satisfied. Currently there is no information on whether the case will be filed to the Supreme Court of Ukraine for reconsideration. Any breach of the Ukrainian Law "On Telecommunications" in the future may negatively influence our business. Article No. 55 of the Ukrainian law "On Telecommunications" states that a license may be terminated, inter alia, in case there is an act on repeated breach of the license terms. In addition, in 2015 the Prosecutor General's Office of Ukraine started criminal proceedings on the fact of "unauthorized intervention" in the operation of MTS Ukraine telecommunication network in Crimea on 15 and 16 March, 2014. The outcome of the investigation is currently unclear. Possible legal risks or risks concerning our license terms and conditions arising from the proceedings might adversely affect our business, financial condition and results of operations.

The level of development of corporate and securities laws and regulations in Russia could limit our ability to attract future investment.

        The regulation and supervision of the securities market, financial intermediaries and issuers are less developed in Russia than, for example, in the United States and Western Europe. Securities laws, including those relating to corporate governance, insider trading, disclosure and reporting requirements, are relatively new, while other laws concerning anti-fraud and directors' and officers' liabilities remain underdeveloped. The Russian securities market is regulated by the CBR and FAS where the latter oversees anti-monopoly matters and advertisement relating to securities.

        In addition, Russian corporate and securities rules and regulations can change rapidly, which may materially adversely affect our ability to conduct capital markets transactions. While some important areas are subject to virtually no oversight, the regulatory requirements imposed on Russian issuers in other areas result in delays in conducting securities offerings and in accessing the capital markets. It is often unclear whether or how regulations, decisions and letters issued by the various regulatory authorities apply to us. As a result, we may be subject to fines and/or other enforcement measures despite our best efforts at compliance, which could have a material adverse effect on our business, financial condition and results of operations.

There is little minority shareholder protection in Russia.

        Minority shareholder protection under Russian law principally derives from (a) supermajority shareholder approval requirements for certain corporate actions, (b) the ability of a shareholder to demand that the company purchase the shares held by that shareholder if that shareholder voted against or did not participate in voting on certain types of actions, and (c) shareholders' right to challenge decisions of the company's management bodies in certain circumstances. Companies are also required by Russian law to obtain the approval of disinterested shareholders for certain transactions with interested parties. In practice, enforcement of these protections has been poor. Shareholders of some companies have also suffered as a result of fraudulent bankruptcies initiated by hostile creditors.

        The supermajority shareholder approval requirement is met by a vote of 75% of all voting shares that are present at a shareholders' meeting. Thus, controlling shareholders owning slightly less than 75% of outstanding shares of a company may have a 75% or more voting power if certain minority shareholders are not present at the meeting. In situations where controlling shareholders effectively have 75% or more of the voting power at a shareholders' meeting, they are in a position to approve amendments to the charter of the company or significant transactions including asset transfers, which could be prejudicial to the interests of minority shareholders. It is possible that our controlling

shareholder in the future may not operate us and our subsidiaries for the benefit of minority shareholders, and this could have a material adverse effect on the value of our shares and ADSs.

        While the Federal Law on Joint Stock Companies of December 26, 1995 as amended (the "Joint Stock Companies Law"), provides that shareholders owning not less than 1% of the company's stock may bring an action for damages caused to a company by its CEO, member of the Board of Directors or is Management Board and certain other officials, minority shareholders may have difficulties with proving such damages with the court and as a consequence may be denied their claims by the court. In 2009, legislation was adopted which contemplates class action litigation. Although there have been several disputes in the past few years, Russian courts do not have a clear and consistent approach in regards to class action litigation. Accordingly, your ability to pursue legal redress against us may be limited, reducing the protections available to you as a holder of our shares and ADSs.

According to Russian legislation, shareholders/participants of Russian companies have an opportunity to demand either liquidation of a company in a judicial proceeding or exclusion of other shareholder/ participant (except for public joint stock companies) from the company.

        According to the amendments to the Civil Code of the Russian Federation which came into effect on September 1, 2014, shareholders and participants of Russian companies have, inter alia, the following rights which can be executed via judicial proceedings:

a)

to demand the liquidation of a company in case of failure to achieve targets for which it was created, including a case when an operation of a company becomes impossible or is substantially hampered; and



b)

to demand exclusion of a shareholder/participant (except for the public joint stock companies, including MTS) whose actions/inactivity either cause significant harm or hampers the company's operations.

        In this regard, considering the lack of practice in applying these regulations, we cannot rule out the possibility of filing of such claims against us. Should such claims be brought, this may have a negative impact on our business, financial condition and results of operations.

Shareholder liability under Russian legislation could cause us to become liable for both obligations of our subsidiaries and losses of the legal entities in which we have a practical possibility of determining actions.

        The Civil Code of the Russian Federation, the Joint Stock Companies Law and the Federal Law "On Limited Liability Companies" generally provide that shareholders in a Russian joint stock company or members of a limited liability company are not liable for the obligations of the company and bear only the risk of loss of their investment. This may not be the case, however, when one entity is capable of determining decisions made by another entity. The entity capable of determining such decisions is deemed an "effective parent." The entity whose decisions are capable of being so determined is deemed an "effective subsidiary." The effective parent bears joint and several responsibility for transactions concluded by the effective subsidiary in carrying out these decisions if:

•

this decision-making capability is provided for in the charter of the effective subsidiary or in a contract between the companies, or due to its majority participation of the effective parent in the charter capital of the effective subsidiary; and



•

the effective parent gives obligatory directions or consent to the effective subsidiary.

        However, joint and several responsibility of the effective parent is excluded in case of voting of the effective parent on the approval of the transaction at a general shareholders' meeting of the effective subsidiary, as well as the approval of the transaction by the executive body of the effective parent, if

55

---

Table of Contents

the need for such approval is envisaged in the charter of the effective subsidiary and (or) the effective parent.

        In addition, an effective parent is secondarily liable for an effective subsidiary's debts if an effective subsidiary becomes insolvent or bankrupt resulting from the action or failure to act of an effective parent. This is the case no matter how the effective parent's ability to determine decisions of the effective subsidiary arises. For example, this liability could arise through ownership of voting securities or by contract. In these instances, other shareholders of the effective subsidiary may claim compensation for the effective subsidiary's losses from the effective parent which caused the effective subsidiary to take action or fail to take action knowing that such action or failure to take action would result in losses. Accordingly, we could be liable in some cases for debts of our subsidiaries and losses of the legal entities in which we have a practical possibility of determining actions if we caused such losses. This liability could have a material adverse effect on our business, results of operations and financial condition.

Shareholder rights provisions under Russian law could impose additional obligations and costs on us, which could have a material adverse effect on our business, financial condition, results of operations and prospects.

        Russian law provides that shareholders that vote against or did not participate in voting on certain matters have the right to sell their shares to the company at market value in accordance with Russian law. The decisions that trigger this right to sell shares include:

•

decisions with respect to a reorganization;



•

the approval by shareholders of a "major transaction," which, in general terms, is a transaction involving property worth more than 50% of the gross book value of our assets calculated according to Russian accounting standards, regardless of whether the transaction is actually consummated;



•

the amendment of our charter in a manner that limits shareholder rights;



•

the amendment of our charter in a manner that excludes reference to the entity's public status, approved simultaneously with a decision on applying to the CBR on release from obligation to disclose information under the laws of the Russian Federation on securities; and



•

a decision on applying for delisting of shares and convertible securities from a stock exchange.

        For example, from 2004 through December 31, 2015, we merged over 60 of our wholly owned subsidiaries into MTS. Following the approval of the first of the series of mergers we repurchased shares from investors who voted against or abstained from voting on the merger in the amount of 11.1 billion rubles. Also, on March 10, 2011, we completed a share buyback as part of the reorganization of MTS involving a merger with Comstar, Dagtelecom and Evrotel. Specifically, a total of 8,000 MTS ordinary shares representing 0.0004% of our issued share capital were repurchased for RUB 1.96 million. In addition, a total of 22,483,791 Comstar ordinary shares representing 5.3809% of issued share capital were repurchased for RUB 4.8 billion. Also as a part of our reorganization during 2013 a total of 90,881 MTS ordinary shares representing 0.004% of our issued share capital were repurchased for RUB 19.7 million and during 2014 a total of 9,935 MTS ordinary shares representing 0.0005% of our issued share capital were repurchased for RUB 2.1 million. In the course of reorganization in 2015 we repurchased 29,666 MTS ordinary shares representing 0.0014% of our issued share capital for RUB 5.9 million.

        Our obligation to purchase shares in these circumstances, which is limited to 10% of the company's net assets calculated in accordance with Russian accounting standards at the time the matter at issue is voted upon, could have a material adverse effect on our business, financial condition, results of operations and prospects. Under Russian law, if we are unable to sell the repurchased shares at a

56

price equal to or exceeding the market price within one year after the date of repurchase, we have to reduce our charter capital accordingly.

The Strategic Foreign Investment Law imposes certain restrictions on us and our existing and potential foreign shareholders, which could have a material adverse effect on our business, financial condition, results of operations and prospects.

        On May 7, 2008, the Federal Law "On the Procedure for Foreign Investment in Commercial Organizations of Strategic Importance for the Defense and Security of the State," or the Strategic Foreign Investment Law, came into force in Russia. This law sets forth certain restrictions relating to foreign investments in Russian companies of "strategic importance." Among others, companies with a dominant position in the Russian telecommunications market are considered to be strategically important and foreign investments in such companies are subject to regulations and restrictions to these companies set out by the Strategic Foreign Investment Law. For purposes of the Strategic Foreign Investment Law, a mobile telecommunications provider is deemed to be dominant if its market share in the Russian market exceeds 25%, as may be determined by FAS. In addition, a company may be considered to be strategically important due to our offering of services involving the use of cryptographic technologies.

        Starting from the effective date of the Strategic Foreign Investment Law, a foreign investor seeking to obtain direct or indirect control over a strategically important company is required to have the respective transaction pre-approved by a special governmental commission on control of foreign investments. On December 6, 2014, the amendments to the Strategic Foreign Investment Law came into effect. The law stipulates that foreign investors are obliged to obtain prior approval of transactions envisaging the acquisition of right of ownership, possession or use of property classified as the fixed production assets of a strategic company and the value of which represents 25% or more of the balance sheet value of the assets of such company as of the last reporting date, according to accounts. In addition, foreign investors are required to notify this authorized governmental body about any transactions undertaken by them resulting in the acquisition of 5% or more of the charter capital of strategically important companies. Within 180 days from the effective date of the Strategic Foreign Investment Law, foreign investors having 5% or more of the charter capital of strategically important companies were required to notify the authorized governmental body about their current shareholding in such companies. Commencing December 6, 2014, a foreign investor is also obliged to notify the authorized governmental body about the fact of conducting the pre-approved transactions.

        As we are classified as a strategically important company, our current and future foreign investors are subject to the notification requirements described above and our current and potential investors may be limited in their ability to acquire a controlling stake in, or otherwise gain control over, us. Such increase in governmental control or limitation on foreign investment could impair the value of your investment and could hinder our access to additional capital.

Regulatory changes in Russia, including the reduction of settlement rate, regulation of other inter-carrier and subscriber tariffs, the mobile number portability principle and others, as well as regulatory changes at the international level may have a material adverse effect on our financial condition and results of operations.

        Following an amendment to the Federal Law on Communications, which became effective July 1, 2006, fixed line operators began charging their subscribers for calls to mobile phone users and started to transfer a percentage of the charge to mobile operators terminating such calls. The percentage transferred to mobile operators is established by the regulator and is known as the "settlement rate." The Ministry of Communications and Mass Media is considering altering the approach to inter-carrier settlements in Russia and the subsequent lowering of the settlement rate. Any reduction of the settlement rate by the regulator could have a negative impact on our average monthly service revenues per subscriber and margins. In September 2013, the Government commission on telecommunications

supported the proposal of the Ministry of Communications and Mass Media to simplify the process of traffic transmission within one sub-federal region, as well as to simplify the process of traffic transmission within the voice and data networks while transmitting voice information within one sub-federal region of the Russian Federation. The exact changes to the current regulations may be significant, including the regulation of interconnect leading to operators' inability to determine the autonomous pricing of interconnect rates.

        In November 2014, the Government of Russia considered a proposal on reconsideration of the interconnect regulation approach submitted by the Ministry of Communications. It is unclear yet how this proposal may be implemented, however it may potentially lead to reduction in traffic transmission revenues. The final decision on the implementation of this proposal has not been made yet.

        The agreement on the conditions of inter-carrier mutual settlements while delivering international communication services in CIS-countries was signed on the CIS Heads of Government Council meeting held in Dushanbe on October 30, 2015 (the "Agreement"). The enforcement of certain provisions of the Agreement may adversely affect our operation in terms of the execution of inter-carrier mutual settlements among CIS-operators. In order to be implemented, the corresponding provisions should be introduced to the Russian legislation. To date, the provisions have not been implemented yet.

        In December 2013 and in July 2014, the State Commission for Radio frequencies introduced a number of modifications to the conditions of using the frequency band for 3G and 4G. These changes resulted in implementation of the principle of technological neutrality for frequency bands 900 MHz (UMTS and LTE) and 1800 MHz (LTE). The Government Regulation No. 480 dated May 24, 2014, requiring that tenders shall be held mainly in the form of auctions, came into force on June 6, 2014. These changes may strengthen competition in the market as well as add costs for development of the network infrastructure.

        The draft law "On Security of Critical Information Infrastructure" may classify our information systems as critical information infrastructure of the Russian Federation, which would involve the need to comply with additional information security requirements and could lead to considerable modernization costs.

        Moreover, a draft law regulating the equipment used in telecommunications network was introduced for consideration by the State Duma of the Russian Federation. This draft law would require us to use telecommunications equipment produced by Russian companies (i.e. those which are tax residents of the Russian Federation). The software in such equipment should have open source code. The draft law permits the use of foreign equipment in case there is no similar equipment produced by Russian companies. It is not yet clear how the restrictions can be applied since there are no Russian producers of much of this equipment. If this draft law is adopted, we could encounter severe difficulties in our operations.

        On February 3, 2014, a plan of measures for "Development of competition in electronic communications" was approved by the Government Regulation No. 130-R. According to the plan, the Ministry of Communications of the Russian Federation and FAS (the functions of Federal Tariff Service were transferred to FAS on July 21, 2015) have to submit to the Government of the Russian Federation a report on assessment of possibility to port subscribers' numbers within fixed line networks ("LNP"-local number portability) as well as within data transmission networks. At the end of January 2015, the press reported that the Ministry of Economic Development submitted to the Ministry of Communications, the Federal Tariff Service, FAS and the Russian Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing a proposal to implement the service of retaining the telephone number after switching from one fixed line operator to another, however the concept of LNP is not yet developed. In March 2015, the press reported that FAS upheld the initiative and suggested to develop pilot projects on launching the service when the Ministry of Communications opposed the proposal. The changes, should they be introduced, may lead to additional costs and

intensify competition. In addition, in case the regulator imposes requirements on granting the infrastructure obligatory for fixed line operators while implementing the service, this may affect our business.

        According to press reports, a proposal on carrying international traffic from the country's territory through the networks of nationwide operators is being considered. The list of nationwide operators has not been specified yet. In case such initiative is implemented and MTS is not included in the list of nationwide operators, this may lead to an increase in our traffic transmission costs.

        According to Government Regulation No. 1240 dated November 24, 2014, starting from January 1, 2015, federal public bodies were vested with a right to make decisions on using data transmission network of government bodies, which is a part of infrastructure ensuring information and technological interaction with the information systems used for rendering state and municipal electronic services for the purposes of exercising public functions. To date, the single operator of infrastructure of electronic state services is Rostelecom. Adoption of the Regulation may adversely affect our revenues with regard to the B2G market segment due to competitive disadvantage.

        On December 9, 2014, Government Regulation No. 1342 adopted the rules of rendering the telephone communications services, that include several amendments. These include an obligation for operators to inform the subscribers of any changes in tariff plans via SMS, the limited ability of operators to charge subscribers for switching to another tariff plan as well as the possibility of subscribers to demand back the advance payments made without termination of contract. Adoption of the rules could materially adversely affect our revenues.

        With the entry into force of the Treaty on the Eurasian Economic Union (EEU) on January 1, 2015, a supra-national antimonopoly body empowered to control compliance with general competition rules on cross-border markets and to apply antitrust measures was established. Should violations with respect to companies operating on cross-border markets be identified, this might lead both, to imposition of fines in accordance with the legislation of the EEU and adoption of the decisions for compulsory execution.

        The amendments introduced to Article 5 of the Federal Law No. 115 "On Combating Legalization (Laundering) of Criminally Gained Income and Financing of Terrorism" dated August 7, 2001, entered into force on March 1, 2015. The list of organizations carrying out cash/other property operations, to whom the law requirements are applied, was expanded according to those amendments. In addition to telecommunication operators entitled to independently render mobile radio telecommunication services, the telecommunication operators occupying "substantial position" in public switched telephone networks entitled to independently provide data transmission services and render services on the basis of contracts with individual subscribers, have been also included in the list. A telecommunication operator which meets the specified criteria is obliged to provide the Federal Financial Monitoring Service with the information on cash/other property operations (that is subject to compulsory control or that seems suspicious while implementing the rules of internal control), as well as to take measures for freezing (blocking) of cash/other property (in case there is an information on its involvement in extremist activities or terrorism). Lack of law enforcement practice may cause difficulties in interpreting the above-mentioned amendments and lead to additional burden for telecommunication operators.

        In June 2015, the Government of Russia introduced the draft amendments to the Federal Law "On Communications" and Federal Law "On Mass Media" providing for use of telecommunication network facilities for the prompt informing of population in case of emergencies. According to the draft law, operators are obliged to transmit warning signals to telecommunication services users in order to provide them with the information of the utmost urgency relating to immediately arising/arisen life or health threats.

        In addition, in June 2015, mass media reported that the Ministry of Communications prepared the draft order pursuant to which telecommunication operators may be obliged to accumulate and store information concerning the personnel actions on communication facilities management (for a 3-year period) and provide it to the Federal Security Service at its request. The intelligence agencies may thus get an access to the data relating to foreign contractors of operators. The compliance with the requirements (in case the order is adopted) may lead to additional costs for the implementation of legislative norms.

        The draft law "On the introduction of amendments to certain legislative acts of the Russian Federation with respect to setting up of additional counter-terrorism measures and public security enforcement" was introduced on April 11, 2016. Pursuant to the draft law, operators may be obliged to store information on the facts of receiving, transferring, delivery and/or processing of voice information and text messages, including their content, as well as images, sounds and other messages of telecommunication services users (for a 3-year period) and provide necessary information to the authorized government bodies in charge of operative-search or security activities (for the execution of their duties prescribed by the federal laws). In case the draft law is approved and adopted in the future, it may impose huge additional costs on the operators of mobile communications.

        Currently the Russian Civil Code is undergoing the process of substantial revisions with new provisions being introduced relating to a number of spheres including property, and a number of others. At present, the potential interpretation of these amendments by state authorities (including the courts), along with their impact on our activities are unknown.

        Russian companies are obliged to pay various and significant taxes including income tax, VAT, real estate tax, excise tax, payroll tax and others. Along with tax liabilities there are different obligatory non-tax payments. These include payments into Universal Service Fund, which currently amounts to 1.2% of our annual revenue on telecommunications services. Furthermore, potential regulatory changes that may be enacted in the future, such as the introduction of new rules regulating MVNOs, new rules concerning our pricing policy and others, could weaken our competitive position in the mobile telecommunications market. Changes in tax laws and non-tax regulations may lead to the growth of our tax burden and may, as a result, materially adversely affect our financial condition and results of operations.

        The changes to the Federal Law "On Communications" regarding the ability of a subscriber to retain the telephone number after switching from one operator of mobile communications to another (mobile number portability ("MNP") were signed by the President of the Russian Federation on December 25, 2012 and came into legal force on December 1, 2013. To enable subscribers to use MNP, a certain number of regulatory legal acts were passed. The introduction of the rules on number portability in mobile networks may lead to subscribers' churn, as well as to an increase in costs for attracting and retaining customers, which may have a significant adverse effect on our financial condition and results of operations. Moreover, the introduction of MNP imposed additional costs on the operators of mobile communications due to the necessity of implementing several complex and resource-intensive actions involving organizational and technical infrastructure, the requirement to improve the software of telecommunication facilities, and change certain business processes.

        There are various difficulties that we face in implementing MNP principle including difficulties in applying established customer practices. The implementation of the MNP principle may therefore lead to the interference of antimonopoly authorities and legal actions. For example, in 2014 MegaFon filed a claim against us after winning a contract on rendering services to the members of the Council of the Federation, which was partially satisfied by FAS.

        From March 1, 2014, if an operator fails to pass a subscriber's number to another operator within the stipulated terms, it is obliged to render the services free of charge. The duration of any free of charge services will start from the planned date of passing the number until the effective date of the

transfer. This initiative came into force on March 1, 2014 and placed additional responsibility on the operators whilst exposing operators to the risk that certain subscribers may seek to improperly take advantage of this system by engineering delays in the MNP process. Starting from April 8, 2014, the operators are obliged to pass a subscriber's number to another operator no later than the eighth day from the individual subscriber's application date and on the twenty ninth day in case the subscriber is a legal entity, unless otherwise indicated in the subscriber's application.

The failure of our subsidiaries that are subject to regulations as natural monopolies to comply with the requirements of the Federal Law No. 223 "On Procurement Process," inter alia, in case of collective tendering can lead to penalties on our subsidiaries.

        One of our subsidiaries, MGTS, is categorized as a natural monopoly in the Moscow telecommunications market. According to the Federal Law No. 223 "On Procurement Process," natural monopolies are obliged to conduct the procurement process in accordance with the principles of transparency and non-discrimination and unjustified limitation of competition. If our subsidiaries that are under additional regulations as natural monopolies are found failing to comply with the law on procurement process, inter alia in case of collective tendering with us, our subsidiaries can be subject to penalties. See also "—Risks Relating to Our Business—If we are found to have a dominant position in the markets where we operate, the government may influence our subscriber tariffs and restrict our operations."

Our failure to comply with new personal data protection laws and with the regulations of state authorities regarding information security in the telecommunications networks in Russia may have a material adverse effect on our business, financial condition and results of operations.

        The activity of a telecommunication operator in the field of information security in the Russian Federation is represented by a variety of regulatory legal acts, such as, Federal Laws "On Communications," "On Information, Information Technology and Information Security," "On Personal Data," "On Trade Secret," "On Electronic Signature," as well as sub-decrees of the Government, the Federal Service for Technical and Export Control, the Federal Security Service, the Ministry of Communications, Roskomnadzor and others.

        As a result of changes in personal data protection regulations, we face significant technical, financial and managerial undertakings. For example, we are required to treat subscribers' personal data with the level of protection afforded to state secrets, obtain state certification of our installed information protection facilities from the Federal Service for Technical and Export Control and the Federal Security Service, obtain licenses for carrying out activity in the field of technical and cryptographic security of personal data from the Federal Service for Technical and Export Control and the Federal Security Service (in case the activity is carried out not only for our own needs). We are also now directly liable for the actions of third parties to whom we forward personal data for processing. Moreover, we must now make public our data protection policies, which currently constitute a trade secret, and which may increase the risk of data protection violations if revealed. Furthermore, the modernization of our information protection systems and the optimization and reengineering of our personal data processing systems will require us to incur significant expenses. At the same time, the regulations established by the Russian government on November 1, 2012 introduced onerous data protection requirements around data processing within the informational systems (for example, to ensure that our system and application software do not have any undeclared capabilities). If the resources required to develop and implement data protection systems meeting the new standards are greater than expected, or we fail to comply with the data protection laws despite our best efforts to do so, our business, financial condition and results of operations could be materially adversely affected.

Recent novelties concerning regulation on personal data such as, for example, ban on processing of Russian citizens' personal data in databases located outside Russia and obligation to provide information concerning all Russian citizens' personal data to "Roskomnadzor" may pose additional compliance risks for telecommunications operators.

        According to the Federal Law No. 242 ("Federal Law No. 242"), operators are obliged to record, systemize, accumulate, store, clarify (update, modify) and retrieve Russian citizens' personal data using databases located only within Russia (subject to a limited number of exceptions), as well as to provide Roskomnadzor with the information on location of databases containing all citizens' personal data.

        The Federal Law No. 242 may cause restrictions on the provision of information services as well as impose penalties on operators for failure to comply with the legal requirements (some of which may be subject to broad interpretation) for a number of reasons including the following:

•

FL-242 prohibits a number of processing actions abroad with respect to personal data of Russian citizens and may, therefore, be interpreted as prohibiting operators to effect cross-border personal data transmission (processing) in the necessary volume and for the necessary period of time which may cause the inability to provide information services for Russian citizens connected with cross-border personal data processing and/or involvement of foreign partners.



•

Telecommunication operator's activity while rendering communication services implies exchange of personal data of Russian citizens with foreign partners. Uncertainties with respect to the Russian legislation do not allow to unambiguously define legitimacy of such activity following the adoption of this law.



•

No standard definition of a database exists at law. According to definitions of a database given in the Article 1260 of the Civil Code and GOST 20886, different documents and virtual objects (for example, MS Office files) may be referred to as a database. The information resources of our company, including personal data, may be stored in a virtual environment (including as part of cloud computing), which may significantly hinder the determination of the exact location of each virtual object and complicate provision of information on such location within the period stipulated by Federal Law No. 152 "On Personal Data." Therefore, the combination of such objects and their location in a complex information structure may be prone to ambiguous interpretation.



•

Partners may violate the procedures for certain prohibited activities with personal data of Russian citizens that is being recorded and systemized by them on behalf of a personal data operator.

        The Federal Law No. 242 entered into force on September 1, 2015. However, in the absence of sufficient official guidance and clear practical enforcement examples, it is hard to form a definitive view on how these new rules would apply, particularly with respect to international companies and telecommunications operators with international presence. Our failure to comply with the legal requirements may lead to the imposition of penalties and restriction on access to Russian websites from the territory of Russia.

Changes in Ukrainian telecommunications legislation have caused uncertainty in relation to the regulation of the Ukrainian telecommunications industry and may adversely affect our business, financial condition and results of operations.

        The Ukrainian Law on Telecommunications came into force on December 23, 2003 (certain articles became effective in 2004 and 2005). The NCRC as the central regulatory body in the sphere of communications was established in August 2004.

62

Table of Contents

        On November 23, 2011, the NCRC was dissolved and the Ukrainian government created the NCCIR. As a result of the NCRC dissolution, the State Inspection of Communications has similarly been dissolved and there are currently no provisions in the legislation that would provide for a similar regulatory body or for its authority. The authority granted to the NCCIR is largely similar to the authority that was afforded to the NCRC.

        In addition, the Ukrainian Law on Telecommunications may require, among other things, companies declared to have dominant position or SMP on the telecommunications market to develop public telecommunications services if directed to do so by the regulatory authorities. On June 24, 2010, MTS Ukraine (among other mobile operators) was found to have a dominant position on the interconnect market by the AMC. In 2012, there have been changes in legislation affecting telecommunications providers including: the Rules on Telecommunication Services making the operators responsible for the actions of content-providers, a law on state lotteries prohibiting all lotteries in Ukraine excluding those of state status and a law on telecommunications prohibiting serving new subscribers unless they provide a passport as identity confirmation.

        In November 2012, NCCIR issued the statements regarding MNP, which enables the subscribers to retain their telephone number after switching from one operator of mobile communications to another. MNP law came into legal force on July 5, 2013 with the beginning of switching to other operators from December 20, 2013. On December 30, 2013 a resolution that postponed the beginning of service provision to July 2014 came into legal force, however, implementation of MNP service was cancelled later on by a court decision. On July 31, 2015, NCCIR approved the procedure for MNP service rendering and introduced amendments to the basic requirements of agreements for the provision of telecommunication services. The decision entered into force on September 8, 2015. The terms of MNP service launch will be set by the special decision of NCCIR which has not been passed yet.

        According to the Law of Ukraine No. 1166 "On prevention of financial disaster and creation of preconditions for the economic growth in Ukraine," the fee for use of radio frequency resource was doubled since April 1, 2014. Over the period of 2016, the fee has raised by 13.35%. The increase in fee for the use of radio frequency resource and similar legislative changes regulating telecommunications industry may materially adversely affect our business, financial condition and results of operations. See "Item 4. Information on Our Company—B. Business Overview—Regulation of Telecommunications in the Russian Federation and Ukraine—Regulation in Ukraine—Legislation."

The Russian taxation system is underdeveloped and any imposition of significant additional tax liabilities could have a material adverse effect on our business, financial condition or results of operations.

        The discussion below provides general information regarding Russian taxes and is not intended to be inclusive of all issues. Investors should seek advice from their own tax advisors as to these tax matters before investing in our shares and ADSs. See also "Item 10. Additional Information—E. Taxation."

        In general, taxes payable by Russian companies are substantial and numerous. These taxes include, among others, corporate income tax, value added tax, property taxes, excise duties, payroll-related taxes and other taxes.

        Russian tax laws, regulations and court practice are subject to frequent change, varying interpretation and inconsistent and selective enforcement. In some instances, although it may be viewed as contrary to Russian constitutional law, the Russian tax authorities have applied certain new tax laws retroactively, issued tax claims for periods for which the statute of limitations had expired and reviewed the same tax period multiple times.

        On October 12, 2006, the Plenum of the High Arbitrazh Court of the Russian Federation issued Resolution No. 53 formulating the concept of "unjustified tax benefit," which is described in the

63

---

Table of Contents

Resolution by reference to circumstances, such as absence of business purpose or transactions where the form does not match the substance, and which could lead to the disallowance of tax benefits resulting from the transaction or the recharacterization of the transaction. There has been very little further guidance on the interpretation of this concept by the tax authorities or courts, but it is likely that the tax authorities will actively seek to apply this concept when challenging tax positions taken by taxpayers in Russian courts. While the intention of this Resolution might have been to combat abuse of tax laws, in practice, there is no assurance that the tax authorities will not seek to apply this concept in a broader sense.

        Generally, tax returns in Russia remain open and subject to tax audit by the tax authorities for a period of three calendar years immediately preceding the year in which the decision to conduct a tax audit is taken. The fact that a year has been reviewed by the tax authorities does not prevent further review of that year, or any tax return applicable to that year, during the eligible three-year period by a superior tax authority or, in certain limited instances, by a tax authority which conducted an initial review.

        On July 14, 2005, the Constitutional Court of the Russian Federation issued a decision that allows the statute of limitations for tax penalties to be extended beyond the three-year term set forth in the tax laws if a court determines that the taxpayer has obstructed or hindered a tax audit. Additionally, according to amendments to the Tax Code of the Russian Federation, effective January 1, 2007, the three-year statute of limitations may be extended if the actions of the taxpayer created insurmountable obstacles for the tax audit. Because none of the relevant terms is defined, tax authorities may have broad discretion to argue that a taxpayer has "obstructed" or "hindered" or "created insurmountable obstacles" in respect of a tax audit and to ultimately seek review and possibly apply penalties beyond the three-year terms. According to Presidium of High Arbitrazh Court Resolution No. 4134/11 of September 27, 2011, the statute of limitations for tax penalties is calculated starting from the day immediately following the expiration of the tax period when the violation was committed.

        On March 17, 2009, the Constitutional Court of the Russian Federation issued a decision preventing the Russian tax authorities from carrying out a subsequent tax audit of a tax period if, following the initial audit of such tax period, a court decision was made concerning a tax dispute between the relevant taxpayer and the relevant tax authority arising out of such tax period, and such decision has not been revised or discharged. The Constitutional Court of the Russian Federation then issued Decision No. 138-O-P on January 28, 2010, which confirmed the above approach. Subsequently, the Presidium of High Arbitrazh Court held in several cases that under certain circumstances (in particular, when the case has not been considered in substance) a superior tax body is still entitled to conduct a tax audit with respect to re-opened tax periods and taxes already reviewed during the initial tax audit; however, the circumstances under which the audit is conducted should differ from the initial ones (No. 14585/09 of March 16, 2010, No. 17099/09 of May 25, 2010, No. 7278/10 of October 20, 2010).

        There is no guarantee that the tax authorities will not review our compliance with applicable tax law beyond the three-year limitation period. Any such review could, if it concluded that we had significant unpaid taxes relating to such periods, have a material adverse effect on our business, financial condition, results of operations and prospects.

        As of January 1, 2012, changes to the Tax Code of the Russian Federation enable Russian taxpayers which are part of a group to consolidate their financial results for profit tax purposes. It is yet unclear how the new legislative provisions will be applied by the tax authorities as currently only limited regulatory guidance is available on this matter. In addition to imposing certain criteria that must be met in order to create a consolidated tax paying group, the law also limits certain transactions within the group (e.g. corporate restructurings). In 2014, we concluded an agreement with tax authorities, according to which the consolidated taxpaying group had to start functioning since 2016.

64

Table of Contents

However, pursuant to the law adopted in November 2015, the contracts on the set up of the consolidated taxpaying group are not subject to registration during 2016 - 2017 and the contracts registered during 2014 - 2015 are considered by tax authorities as not registered. In the absence of any official interpretation, it is currently difficult to estimate the implementation of new law on the agreements already registered by tax authorities.

        In addition, intercompany dividends are subject to a withholding tax of 0% or 13% (depending on whether the recipient of dividends qualifies for Russian participation exemption rules), if being distributed to Russian companies, and 15% (or lower, subject to benefits provided by relevant double tax treaties), if being distributed to foreign companies.

        The Russian tax authorities may take a more assertive position in their interpretation of the legislation and assessments, and it is possible that transactions and activities that have not been challenged in the past may nonetheless be subject to challenges in the future. The foregoing factors raise the risk of the imposition of arbitrary or onerous taxes on us, which could adversely affect the value of our shares and ADSs.

        Current Russian tax legislation is, in general, based upon the formal manner in which transactions are documented, looking to form rather than substance. However, the Russian tax authorities are increasingly taking a "substance and form" approach, which may cause additional tax exposures to arise in the future. Additional tax exposures could have a material adverse effect on our business, financial condition, results of operations and prospects.

        It is expected that Russian tax legislation will become more sophisticated, which may result in the introduction of additional revenue raising measures. Although it is unclear how any new measures would operate, any such introduction may affect our overall tax efficiency and may result in significant additional taxes becoming payable. Additional tax exposures could have a material adverse effect on our business, financial condition, results of operations and prospects.

        In addition to the usual tax burden imposed on Russian taxpayers, these conditions complicate tax planning and related business decisions. For example, tax laws are unclear with respect to deductibility of certain expenses. This uncertainty could possibly expose us to significant fines and penalties and to enforcement measures, despite our best efforts at compliance, and could result in a greater than expected tax burden.

        See also "Item 8. Financial Information—A. Consolidated Statements and Other Financial Information—7. Litigation—Tax Audits and Claims."

Lack of law enforcement practice of the Russian anti-offshore policy may have adverse impact on our business, financial condition and results of operations.

        In the past few years, the Russian Federation like a number of other countries in the world has been actively involved in a discussion of measures against tax evasion by the use of low tax jurisdictions as well as aggressive tax planning structures.

        The rules of controlled foreign companies (CFC) came into force on January 1, 2015. The rules oblige Russian taxpayers being controlling persons of a foreign company to submit to the tax authorities both standard notifications on participation in CFC and tax declarations. Profit generated commencing in 2015, including retained earnings, is subject to taxation in the Russian Federation. The innovations could impose additional tax on the undistributed profits of any foreign entity controlled by us (in proportion to such controlling stake) at the rate of 20%. These innovations caused amendments to the Tax Code providing for liability in case of non-disclosure or incomplete disclosure of information on CFCs and the non-payment or underpayment of relevant tax.

        In addition, implementation of new concept of beneficial ownership, with regard to taxation of payment of passive income (dividends, royalty, income), may negatively affect possibility to apply benefits set by the double tax treaties, in case such payments pass through intermediary entities. This may potentially lead to increase of tax burden with regard to such payments.

        On November 4, 2014, the President of the Russian Federation signed the Federal law No. 325 "On ratification of the Convention on Mutual Administrative Assistance in Tax Matters."

        Ratification of this Convention will enable the Russian Federation to receive tax information from all participating countries which include, among others, a number of offshore jurisdictions.

        Lack of law enforcement practice may cause difficulties in interpreting the above-mentioned laws by the Russian tax authorities. It is also currently unclear how the enacted laws could affect our counterparties, which may be registered in off shore jurisdictions.

        In case the impact of legislative initiatives is significant for some of our counterparties it may lead to potential influence on our results of operations.

The tax system in Ukraine is undergoing a reform and various tax laws are subject to different interpretations.

        Besides the new Tax Code, which came into force on January 1, 2011, Ukraine currently has a number of laws related to various taxes imposed by both central and regional authorities. Applicable taxes include value added tax ("VAT"), corporate income tax (profits tax), customs duties, payroll (social) taxes and other taxes. These tax laws have not been in force for significant periods of time compared to more developed market economies and are constantly changed and amended. Accordingly, few precedents regarding tax issues are available.

        Although the Ukrainian Constitution prohibits retroactive enforcement of any newly enacted tax laws and the Law on Taxation System specifically requires legislation to adopt new tax laws at least six months prior to them becoming effective, such rules have largely been ignored. In addition, tax laws are often vaguely drafted, making it difficult for us to determine what actions are required for compliance.

        Furthermore, with the entry into force of the new Tax Code of Ukraine (the "TCU"), there is uncertainty in regards to tax accounting of payments for the use of computer software. As part of its business, MTS Ukraine purchases limited end-user rights for the use of computer software. Currently, there are no clear rules for the classification of the payments made by MTS Ukraine for these purchases. Under the TCU, these payments may be treated as payments for intangible assets or as payments for fixed assets. Tax authorities of different levels have provided inconsistent tax clarifications on this matter. The tax rate applicable to these payments will vary according to their classification.

        Also, rules established by the TCU for recalculation of the input tax credit for non-current assets are unclear. Uncertain transfer pricing rules and their inconsistent application by the Ukrainian tax authorities and courts may also adversely affect MTS Ukraine's operations. MTS Ukraine's transactions with its related parties as well as certain transactions with non-Ukrainian entities that are not MTS Ukraine's related parties may be affected by the application of the transfer pricing rules. No "safe harbor" margin is provided under Ukrainian legislation if the sale price deviates from the arm's length price.

        On December 28, 2014, the Act on Improvement of Tax Control on Transfer Pricing was approved. From January 1, 2015, business transactions that have an impact on taxable profits with related parties non-Ukrainian entities or non-related entities of states, where the Corporate Profits Tax rate is less than 13%, are controlled if the value of all transactions with the same counterparty exceeds 1 million hryvnias (net of VAT).

        Due to the poor quality of the applicable tax legislation and its inconsistent interpretation, it is possible that MTS Ukraine's prices could be subject to challenge and adjustment for corporate income tax or VAT purposes. Profit repatriation arrangements, such as the level of royalties for trademarks or loan interest paid by MTS Ukraine from Ukraine abroad, may also be challenged for the same reasons. If such price adjustments are implemented, MTS Ukraine's effective tax rate may increase and its financial results may be adversely affected.

        Differing opinions regarding the legal interpretation of tax laws often exist both among and within governmental ministries and organizations, including the tax administration, creating uncertainties and areas of conflict for taxpayers and investors.

        Tax declarations/returns, together with other legal compliance areas (e.g., customs and currency control matters), may be subject to review and investigation by various administrative divisions of the tax authorities, which are authorized by law to impose severe fines, penalties and interest charges. These circumstances create tax risks in Ukraine substantially more significant than typically found in countries with more developed tax systems. Generally, tax declarations/returns in Ukraine remain open and subject to inspection for a three-year period. However, this term may not be observed or may be extended under certain circumstances, including in the context of a criminal investigation.

        The changes introduced into the Tax Code of the Ukraine during 2012 created a duty to pay advance installments on tax on profits on a monthly basis and retained the duty to pay advance installments on dividend payments. Before 2013, tax on profits charged for the accounting period was reduced by the amount of advance installments made on dividend payments. In 2013, such reductions were not taken into account and we were obliged to pay the new monthly advance installment on the tax on profits as well as the advance installments on the dividend payments, which increased our tax expenses. However, following a new law issued on July 31, 2013 it became possible to reduce the tax on profits by the amount of advance installments on dividend payments but commencing March 1, 2014 when the 2013 and 2014 tax return is filed. But the form of tax return applied for 2013, 2014 and 2015 does not provide for such reduction. The State Fiscal Service provided similar clarifications on the possibility to reduce the tax on profits in tax report for 2015 by the amount of advance installments made on dividend payments in previous years.

        The approach to the calculation of the profits tax has changed recently. The tax is currently calculated based on financial results declared in the financial statements, i.e. according to the accounting principles. There were temporary tax differences for specific operations until January 1, 2015, i.e. the revenues reflected in the financial statements for 2015 were also reflected in tax accountings until January 1, 2015, which could lead to double taxation. MTS Ukraine is working with the relevant state authorities to avoid double taxation.

        On March 27, 2014, the Act on Finance Crisis Prevention was passed in Ukraine. Several provisions in the Tax Code have been changed by the act which may affect our business in Ukraine, in particular, doubling of the fees for frequency usage.

        On December 28, 2014, the Act on tax reform was passed, that changes TCU by introducing the new VAT base and the electronic VAT administration system. From January 1, 2015 the VAT base for taxable supplies cannot be lower than the purchase price for purchased goods/services and/or the cost for produced services (cannot be lower than the normal price from January 1, 2016); and/or the net balance value of non-current assets. From February 1, 2015 till October 1, 2015 the electronic VAT administration system operated in a test regime: all VAT invoices were issued in electronic form and registered in the unified register. Failure to register a VAT invoice issued since October 1, 2015 on time is subject to 20-50% fines depending on the overdue period. Since July 1, 2015, the registration of VAT invoices is available if the supplier has sufficient input VAT and/or has a sufficient balance in its State Treasury electronic VAT account accumulated with cash from supplier's bank account. In addition, starting from January 1, 2016 10-100% fines for errors on VAT invoices were introduced.

        While we believe that we are currently materially in compliance with the tax laws affecting our operations in Ukraine, it is possible that relevant authorities may take differing positions with regard to interpretative issues, which may result in a material adverse effect on our results of operations and financial condition.

Vaguely drafted Russian transfer pricing rules, and lack of reliable pricing information may impact our business and results of operations.

        Russian transfer pricing legislation became effective in the Russian Federation on January 1, 1999. This legislation allowed the tax authorities to make transfer pricing adjustments and impose additional tax liabilities with respect to all "controlled" transactions, provided that the transaction price differed from the market price by more than 20%. "Controlled" transactions included transactions with related parties, barter transactions, foreign trade transactions and transactions with significant price fluctuations (i.e., if the price with respect to such transactions differs from the prices on similar transactions conducted within a short period of time by more than 20%). Special transfer pricing provisions were established for operations with securities and derivatives. Russian transfer pricing rules were vaguely drafted, generally leaving wide scope for interpretation by Russian tax authorities and courts. There has been very little guidance (although some court practice is available) as to how these rules should be applied. These transfer pricing rules apply with respect to transactions that occurred before January 1, 2012.

        New transfer pricing rules became effective on January 1, 2012. The implementation of these new rules should help to align domestic rules with OECD principles. The new rules are expected to considerably toughen the previously effective law by, among other things, effectively shifting the burden of proving market prices from the tax authorities to the taxpayer and obliging the taxpayer to keep in certain cases specific documentation. In addition, the amendments:

•

introduce the possibility for major taxpayers to enter into an advance pricing agreement with the tax authorities;



•

introduce the 'arm's length' principle as a fundamental principle of the Russian transfer pricing rules;



•

establish a new list of controlled transactions (which would cover cross-border transactions with certain commodities, cross-border transactions with related parties and tax haven residents, and certain intra-Russian transactions with related parties);



•

extend the list of related parties;



•

extend the list of transfer pricing methods (including the Transactional Net Margin Method and the Profit Split method) with the choice of method depending on the allocation of functions performed, risks assumed and assets used by the parties to a transaction (instead of a rigid priority of methods under prior legislation);



•

replace the existing permitted deviation threshold with the 'arm's length' range of market prices (profitability);



•

introduce double-side adjustments in relation to domestic transactions; and



•

introduce special transfer pricing audits by federal tax authorities and specific transfer pricing penalties (more severe that in case of other, non-transfer pricing related, tax assessments).

        If the Russian tax authorities were to impose significant additional tax liabilities through the introduction of transfer pricing adjustments, they could have a material adverse impact on our business, financial condition and results of operations. Adoption of the new transfer pricing rules may increase the risk of transfer pricing adjustments being made by the tax authorities. In addition to the usual tax

68

Table of Contents

risks and tax burden imposed on Russian taxpayers, the uncertainties of the new transfer pricing rules complicate tax planning and related business decisions. It will also require us to ensure compliance with the new transfer pricing documentation requirements proposed in such rules. Uncertainty of the new rules may also require us to expend significant additional time and material resources for implementation of our internal compliance procedures. Tax authorities could impose additional tax liability as well as 20% penalties on the underpaid tax in case the prices or profitability are outside the market range and if the required transfer pricing documentation has not been prepared, which could have a material adverse effect on our results of operations and financial condition.

The regulatory environment for telecommunications in Russia, Ukraine and other countries where we operate or may operate in the future is uncertain and subject to political influence or manipulation, which may result in negative and arbitrary regulatory and other decisions against us on the basis of other than legal considerations and in preferential treatment for our competitors.

        We operate in an uncertain regulatory environment. The legal framework with respect to the provision of telecommunications services in Russia and Ukraine and the other countries where we operate or may operate in the future is not well developed, and a number of conflicting laws, decrees and regulations apply to the telecommunications sector.

        Moreover, regulation is conducted largely through the issuance of licenses and instructions, and governmental officials have a high degree of discretion. In this environment, political influence or manipulation could be used to affect regulatory, tax and other decisions against us on the basis of other than legal considerations. For example, Russian government authorities investigated VimpelCom in late 2003 on grounds that it was illegally operating in Moscow pursuant to a license issued to its wholly owned subsidiary rather than to VimpelCom itself. In addition, some of our competitors may receive preferential treatment from the government, potentially giving them a substantial advantage over us.

An adverse change in the infrastructure regulation in Russia could result in additional costs on us.

        From January 1, 2013, telecommunications operators are required to enter into agreements with owners of roads whose public access areas host telecommunication equipment. These agreements have to contain certain provisions prescribed by the Russian Ministry for Transportation and the Russian Ministry for Economic Development and Trade. To date, no list of such provisions has been adopted. There is a risk of imbalance in the commercial interests of the operators and road owners in case such list is adopted.

        Consequently, any adverse changes in legislation relating to the regulation of interaction between the owners of roads and telecommunications companies could have a material adverse effect on our business, financial condition, results of operations and prospects.

        Telecom operators will be obliged to sign agreements with both, owners of the roads and with owners of land located within road areas where telecommunication equipment is installed. On September 5, 2014, the Ministry of Transport adopted Order No. 240 "On approval of the procedure for determination of fees for public easements in respect of land plots within the boundaries of road rights-of-way (except for private roads) for laying, moving, conversion and operations of utility lines." The Order establishes annual payment in the amount of 0.12% of the cadastral cost of the land plot.

        After the Ministry of Transport of the Russian Federation in coordination with the Ministry of Economic Development adopts the Order setting out key terms of agreements between telecommunications operators and owners of the roads, telecommunications operators will be obliged to enter into these agreements. Federal public bodies are currently considering a draft of the Order.

Risks Relating to the Shares and ADSs and the Trading Market

Government regulations may limit the ability of investors to deposit shares into our ADS facility.

        The ability of investors to deposit shares into our ADS facility may be affected by current or future governmental regulations. For example, under Russian securities regulations, no more than 25% of a Russian company's shares may be circulated abroad through sponsored depositary receipt programs. Prior to December 31, 2005, and at the time of our initial public offering, this threshold was 40%. Although we believe that the new lower threshold does not apply to our ADSs, in the future, we may be required to reduce the size of our ADS program or amend the depositary agreement for the ADSs.

        Because our ADS program is regularly at or near capacity, purchasers of our shares may not be able to deposit these shares into our ADS facility, and ADS holders who withdraw the underlying shares from the facility may not be able to re-deposit their shares in the future. As a result, effective arbitrage between our ADSs and our shares may not always be possible. Our shares are listed and traded on the Moscow Interbank Currency Exchange. Due to the limited public free float of our common stock, the public market for our shares is significantly less active and liquid than for our ADSs. The cumulative effect of these factors is that our shares may from time to time, and for extended periods of time, trade at a significant discount to our ADSs.

Recent Russian legislation changed the approach towards disclosure of information about ownership of the ADSs, including in some cases beneficial ownership of the ADSs, and a failure to provide such disclosure may restrict your ability to vote.

        Pursuant to recently changed legislation, depositaries, and as a result, ADS holders, are not able to vote in connection with the shares underlying ADSs on behalf of the ADS holders unless they provide certain information to the issuer. At a minimum, this information includes the identity of the holder of the ADSs, registration details including a state registration number (for legal entities), and the number of shares attributable to each ADS holder.

        Nevertheless the legislation stipulates that the issuer, CBR, Russian courts and pretrial investigation agencies may request such lists of depositary receipt holders from the holder of depositary program depo account. The holder of depositary program depo account shall take all reasonable measures in order to provide such information. In case of non-compliance with the above requirements, the CBR may suspend, or impose limitations on, transactions with securities held in the relevant accounts of Russian custodians for a period of up to six months. As a result, the shares underlying the ADSs may be blocked and it may be impossible to deposit or withdraw the shares into or from the depositary program. Overall, there is lack of practice and official interpretation in relation to the new rules related to shares underlying ADSs as well as uncertainties with respect to exercise of certain rights attaching to shares underlying ADS holders in view of the new rules which could complicate the exercise of right to, and the ability to derive benefits from, the shares represented by ADSs.

The market price of our ADSs has been and may continue to be volatile.

        The market price of our ADSs experienced, and may continue to experience, significant volatility. For information on the closing price of our ADSs on the New York Stock Exchange, see "Item 9. Offer and Listing Details—A.4. Market Price Information."

        Numerous factors, including many over which we have no control, may have a significant impact on the market price of our ADSs, including, among other things:

•

periods of regional or global macroeconomic instability;



•

announcements of technological or competitive developments;

70

---

Table of Contents

•

regulatory developments in our target markets affecting us, our customers or our competitors;



•

actual or anticipated fluctuations in our quarterly operating results;



•

changes in financial estimates or other material comments by securities analysts relating to us, our competitors or our industry in general;



•

announcements by other companies in our industry relating to their operations, strategic initiatives, financial condition or financial performance or to our industry in general;



•

announcements of acquisitions or consolidations involving industry competitors or industry suppliers;



•

sales or perceived sales of additional ordinary shares or ADSs by us or our significant shareholders; and



•

impact and development of any investigation or lawsuit, currently pending or threatened, or that may be instituted in the future.

        For example, market price of our ADSs experienced significant volatility during 2014 due to an economic downturn coupled with legal proceedings relating to our beneficial owner, as disclosed in more detail by Sistema.

        In addition, the stock market in recent years has experienced extreme price and trading volume fluctuations that often have been unrelated or disproportionate to the operating performance of individual companies. These broad market fluctuations may adversely affect the price of our ADSs, regardless of our operating performance.

Voting rights with respect to the shares represented by our ADSs are limited by the terms of the deposit agreement for our ADSs and relevant requirements of Russian law.

        ADS holders will have no direct voting rights with respect to the shares represented by the ADSs. They are able to exercise voting rights with respect to the shares represented by ADSs only in accordance with the provisions of the deposit agreement relating to the ADSs and relevant requirements of Russian law. Therefore, there are practical limitations upon the ability of ADS holders to exercise their voting rights due to the additional procedural steps involved in communicating with them. For example, the Joint Stock Companies Law and our charter require us to notify shareholders no less than 30 days prior to the date of any meeting and at least 70 days prior to the date of an extraordinary meeting to elect our Board of Directors. Our ordinary shareholders will receive notice directly from us and will be able to exercise their voting rights by either attending the meeting in person or voting by power of attorney.

        ADS holders by comparison, will not receive notice directly from us. Rather, in accordance with the deposit agreement, we will provide the notice to the depositary. The depositary has undertaken, in turn, as soon as practicable thereafter, to mail to ADS holders the notice of such meeting, voting instruction forms and a statement as to the manner in which instructions may be given by ADS holders. To exercise their voting rights, ADS holders must then instruct the depositary how to vote the shares represented by the ADSs they hold. Because of this additional procedural step involving the depositary, the process for exercising voting rights may take longer for ADS holders than for holders of the shares and we cannot assure ADS holders that they will receive voting materials in time to enable them to return voting instructions to the depositary in a timely manner. ADSs for which the depositary does not receive timely voting instructions will not be voted.

        Given the above, we cannot provide any assurance that holders and beneficial owners of ADSs will (i) receive notice of shareholder meetings to enable the timely return of voting instructions to the depositary, (ii) receive notice to enable the timely cancellation of ADSs in respect of shareholder

71

actions or (iii) be given the benefit of dissenting or minority shareholders' rights in respect of an event or action in which the holder or beneficial owner has voted against, abstained from voting or not given voting instructions.

        See also "—Recent Russian legislation changed the approach towards disclosure of information about ownership of the ADSs, including in some cases beneficial ownership of the ADSs, and a failure to provide such disclosure may restrict your ability to vote."

ADS holders may be unable to repatriate distributions made on the shares and ADSs.

        We anticipate that any dividends we may pay in the future on the shares represented by the ADSs will be declared and paid to the depositary in rubles and will be converted into U.S. dollars by the depositary and distributed to holders of ADSs, net of the depositary's fees and expenses. The ability to convert rubles into U.S. dollars is subject to the availability of U.S. dollars in Russia's currency markets. Although there is an existing, albeit limited by size, market within Russia for the conversion of rubles into U.S. dollars, including the interbank currency exchange and over-the-counter and currency futures markets, the further development of this market is uncertain. At present, there is a limited market for the conversion of rubles into foreign currencies outside of Russia and limited market in which to hedge ruble and ruble-denominated investments.

ADS holders may be subject to Russian regulatory restrictions.

        Prior to the amendments to the Russian securities laws introduced in 2011, a depositary bank could be considered the owner of the shares underlying the ADS, and as such could be subject to the mandatory public tender offer rules, anti-monopoly clearance rules, governmental consents or reporting requirements in respect of acquisition of shares and other limitations contemplated by Russian law. The amendments to the Russian securities laws introduced in 2011 provide that a depositary bank is not an owner of underlying shares, and as such, these requirements should apply to ADS holders.

ADS holders may be unable to benefit from the United States—Russia income tax treaty.

        Under Russian law, dividends paid to a non-resident holder of the shares generally will be subject to Russian withholding tax at a rate of 15%. The tax burden may be reduced to 5% or 10% under the United States—Russia income tax treaty for eligible U.S. holders; a 5% rate may potentially apply for U.S. holders who are legal entities owning 10% or more of the company's voting shares, and a 10% rate applies to dividends paid to eligible U.S. holders in other cases, including dividend payments to individuals and legal entities owning less than 10% of the company's voting shares. However, according to the recent amendments to the Tax Code, U.S. holders will only be able to utilize the 5% reduced rate through tax reimbursement procedures, as the tax agent is required to use the baseline tax rate established by the code or the applicable tax treaty, whichever is appropriate. See also "Item 10. Additional Information—E. Taxation—United States—Russia Income Tax Treaty Procedures."

        The Russian tax rules in relation to ADS holders (that would affect U.S. holders) are characterized by significant uncertainties and limited interpretive guidance. Recent amendments to the tax rules have clarified the status of the ADS holders as beneficial owners of the income from the underlying shares by establishing that the custodian holding the depo account with the shares underlying the ADSs acting as the tax agent and determines amounts of the withholding tax based on the information about the ADS holders and their tax residency status as provided by the program depositary. However, the application of the baseline tax rate for ADS holders and any double tax treaty relief is available only if the tax treaty residence of the holder is provided to the custodian along with the other information prescribed by the Tax code. In relation to ADS holders such information is to be provided by the ADS holders to the depositary, who relays it to the custodian, who acts as the tax agent and withholds the taxes when making transferring the dividends to the depositary. It is currently unclear how the

72

Table of Contents

depositary will collect the necessary information from ADS holders. Thus, while a U.S. holder may technically be entitled to benefit from the provisions of the United States—Russia income tax treaty, in practice such relief may be difficult or impossible to obtain. See also "Item 10. Additional Information—E. Taxation" for additional information.

Capital gain from the sale of shares and ADSs may be subject to Russian income tax.

        Income received by a foreign company from the sale, exchange or other disposal (assuming that such income is not related to a permanent establishment of a foreign company in Russia) of shares (participation interest) in an organization in which over 50% of the assets consist of immovable property located in Russia, as well as financial instruments derived from such shares, is treated as income derived from a source in the Russian Federation and is subject to withholding tax at a rate of 20%. However, gains arising from the disposition of the securities which are traded on an organized stock exchange are not treated as Russian-source income, and should not be subject to taxation in Russia.

        The amount of such income is typically determined as the sales price of shares (participation interest). However, if documentary support for the acquisition cost of the shares (participation interest) is available, the tax may instead be assessed on the basis of the difference between the sales price and the acquisition cost (including other related costs) if documentary evidence of such costs is submitted to the tax agent. The Russian Tax Code also establishes special rules for calculating the tax base for the purposes of transactions with securities. However, an exemption applies if immovable property located in Russia constitutes more than 50% of a company's assets and the securities are traded on a foreign stock exchange. The determination of whether more than 50% of our assets consist of immovable property located in Russia is inherently factual and is made on an on-going basis and the relevant Russian legislation and regulations in this respect are not entirely clear. Hence, there can be no assurance that immovable property owned by us and located in Russia does not currently and will not constitute more than 50% of our assets as at the date of the sale of ADSs by non-residents.

        Where the ADSs are sold by legal entities or organizations to persons other than a Russian company or a foreign company or an organization with a registered permanent establishment in Russia, even if the resulting capital gain is considered taxable in Russia, there is currently no mechanism under which the purchaser will be able to withhold the tax and remit it to the Russian budget.

        Under the United States—Russia income tax treaty, capital gains from the sale of shares and/or ADSs by eligible U.S. holders should be relieved from taxation in Russia, unless 50% or more of our assets (the term "fixed assets" is used in the Russian version of the treaty) were to consist of immovable property located in Russia.

        The taxation of income of non-resident individuals depends on whether this income is received from Russian or non-Russian sources. Russian tax law does not give a definition of how the "source of income" should be determined with respect to the sale of securities, other than that income from the sale of securities which takes place "in Russia" should be considered as Russian source income. As there is no further definition of what should be considered to be a sale "in Russia," the Russian tax authorities have a certain amount of freedom to conclude what transactions take place in or outside Russia, including looking at the place of the transaction, the place of the issuer of the shares, the location of the registrar recording the transfer of legal title to the relevant securities or other similar criteria.

        Non-residents who are individuals are taxable on Russian-source income. Provided that gains arising from the disposition of the foregoing types of securities and derivatives outside of Russia by U.S. holders who are individuals not resident in Russia for tax purposes will not be considered Russian source income, then such income should not be taxable in Russia. However, gains arising from the disposition of the same securities and derivatives "in Russia" by U.S. holders who are individuals not

73

Table of Contents

resident in Russia for tax purposes may be subject to tax either at the source in Russia or based on an annual tax return, which they may be required to submit with the Russian tax authorities. See also "Item 10. Additional Information—E. Taxation."

The lack of a developed practice relating to share registration system in Russia and other countries where we operate may result in improper record ownership of our shares, including the shares underlying the ADSs, and other problems connected with the rights attributed to the relevant shares such as dividend payments.

        Ownership of Russian joint stock company shares (or, if the shares are held through a nominee or custodian, then the holding of such nominee or custodian) is determined by entries in a share register and is evidenced by extracts from that register. Currently, the central registration system in Russia is under development. Since October 1, 2014, share registers of all joint stock companies are maintained by licensed registrars. Regulations were issued regarding the licensing conditions for such registrars, as well as the procedures to be followed by both companies maintaining their own registers and licensed registrars when performing the functions of registrar, however companies are no longer able to maintain the registers themselves. Nevertheless, in practice registrars tend to have relatively low levels of capitalization and insufficient insurance coverage.

        On December 7, 2011 amendments to the relevant legislation were adopted, substantially reforming the registration system by introducing the CSD. In the course of this reform of the share keeping system, numerous different depositaries with accounts in the registers of companies were replaced by a single central depositary, whose primary function is the custody of shares in all major companies. These changes became effective on January 1, 2012 and are still being implemented. On November 6, 2012, FSFM officially appointed the National Settlement Depositary as the central depositary. Since the central depositary opened its account in MTS' register in March 2013, all the other custodians are restricted from opening their accounts in the register. Currently the central depositary is the only custodian with an account in MTS' register and other custodians hold custodial accounts with the central depositary.

        In addition, certain amendments to the Civil Code of the Russian Federation entered into force on October 1, 2013 regarding the transfer and restitution of securities that are aimed at protection of rights of security holders and on September 1, 2014 regarding the regulation of legal entities and their corporate governance. However, a centralized share registration system is currently undergoing a reform in Russia, therefore transactions in respect of a company's shares could be improperly or inaccurately recorded, and share registration could be lost through fraud, negligence, official and unofficial governmental actions or oversight by registrars incapable of compensating shareholders for their misconduct. This creates risks of loss not normally associated with investments in other securities markets.

        In addition, on July 6, 2012 a central depositary was introduced in Ukraine. Such central depositary is to hold the shares of all joint stock companies in Ukraine. The methods of dividend payments was also changed: according to the new rules the joint-stock company transfers dividends to the CSD through the operating account at the special processing center in order to enable the central depositary make the onward transfer to the parties eligible to receive dividends. The changes came into force on October 12, 2013 and could affect the timing of dividend payouts.

        The Regulation No. 591 of the National Bank of Ukraine "On amendments to Certain Legislative Acts of the National Bank of Ukraine" that entered into force on September 23, 2014 and expired on December 2, 2014 set the restriction on a number of operations in foreign currency, including repatriation of dividends to the foreign investor. On December 1, 2014, the National Bank of Ukraine adopted a new regulation (Resolution No. 758) with effect from December 3, 2014, which extended the application of certain currency control restrictions, including the above-mentioned repatriation of dividends (except for the dividends on securities traded on stock exchange) till March 3, 2015. During

74

the course of 2015 and the first quarter of 2016, the restriction terms have been prolonged several times, with the expiration on June 8, 2016, which may adversely affect our cash flow and results of operations.

Foreign judgments may not be enforceable against us.

        Our presence outside the United States may limit your legal recourse against us. We are incorporated under the laws of the Russian Federation. Substantially all of our directors and executive officers named in this document reside outside the United States. All or a substantial portion of our assets and the assets of our officers and directors are located outside the United States. As a result, you may not be able to effect service of process within the United States on us or on our officers and directors. Similarly, you may not be able to obtain or enforce U.S. court judgments against us, our officers and directors, including actions based on the civil liability provisions of the U.S. securities laws. In addition, it may be difficult for you to enforce, in original actions brought in courts in jurisdictions outside the United States, liabilities predicated upon U.S. securities laws.

        There is no treaty between the United States and the Russian Federation providing for reciprocal recognition and enforcement of foreign court judgments in civil and commercial matters. These limitations may deprive you of effective legal recourse for claims related to your investment in our shares and ADSs. The deposit agreement provides for actions brought by any party thereto against us to be settled by arbitration in accordance with the Commercial Arbitration Rules of the American Arbitration Association, provided that any action under the U.S. federal securities laws or the rules or regulations promulgated thereunder may, but need not, be submitted to arbitration. The Russian Federation is a party to the United Nations (New York) Convention on the Recognition and Enforcement of Foreign Arbitral Awards, but it may be difficult to enforce arbitral awards in the Russian Federation due to a number of factors, including the inexperience of Russian courts in international commercial transactions, official and unofficial political resistance to enforcement of awards against Russian companies in favor of foreign investors and Russian courts' inability to enforce such orders and corruption.

Other Risks

We have not independently verified information we have sourced from third parties.

        We have sourced certain information contained in this document from third parties, including private companies and Russian government agencies, and we have relied on the accuracy of this information without independent verification. The official data published by Russian federal, regional and local governments may be substantially less complete or researched than those of more developed countries. Official statistics may also be produced on different bases than those used in Western countries. Any discussion of matters relating to Russia in this document must, therefore, be subject to uncertainty due to concerns about the completeness or reliability of available official and public information. In addition, the veracity of some official data released by the Russian government may be questionable. In 1998, the Director of the Russian State Committee on Statistics and a number of his subordinates were arrested and subsequently sentenced by a court in 2004 in connection with their misuse of economic data.

Table of Contents

Because no standard definition of an average monthly service revenue per user ("ARPU"), average monthly usage per user ("MOU") or churn exists in the telecommunications industry, comparisons between certain operating data of different companies may be difficult to draw.

        The methodology for calculating subscriber numbers, ARPU, MOU and churn varies substantially in the telecommunications industry, resulting in variances in reported numbers from that which would result from the use of a uniform methodology. Therefore, comparisons of certain operating data between different telecommunications companies may be difficult to draw.

Item 4.    Information on Our Company

A.    History and Development

        Mobile TeleSystems CJSC ("MTS CJSC") our predecessor, was formed in 1993. The founding shareholders included MGTS and three other Russian telecommunications companies, which collectively held 53% of our original share capital, and two German companies, Siemens AG and T-Mobile Deutschland GmbH, an affiliate of Deutsche Telekom AG, which collectively held the remaining 47%. Sistema currently owns 51.46% of our share capital (53.46% excluding treasury shares). See "Item 7. Major Shareholders and Related Party Transactions—A. Major Shareholders."

        Our legal name is Mobile TeleSystems Public Joint Stock Company (MTS PJSC) and we are incorporated under the laws of the Russian Federation. Our head office is located at 5 Vorontsovskaya Street, Bldg. 2, Moscow 109147, Russian Federation, and the telephone number of our investor relations department is +7 495 223-2025. The address of our incorporation is 4 Marksistskaya Street, Moscow 109147, Russian Federation. We maintain a website at www.mtsgsm.com. The information on our website is not a part of this report. We have appointed Puglisi & Associates, 850 Library Avenue, Suite 204, Newark, Delaware 19715 as our authorized agent for service of process for any suit or proceeding arising out of or relating to our shares, ADSs or the deposit agreement.

        MTS PJSC is the new legal name of Mobile TeleSystems Open Joint Stock Company (MTS OJSC) registered on July 1, 2015 in order to comply with the regulations of Chapter 4 of the Civil Code of Russian Federation (as amended). MTS OJSC was created on March 1, 2000, through the merger of MTS CJSC and RTC CJSC, a wholly owned subsidiary. Our charter was registered with the State Registration Chamber on March 1, 2000, which is our date of incorporation, and with the Moscow Registration Chamber on March 22, 2000. Our initial share issuance was registered by the Russian Federal Commission on the Securities Market on April 28, 2000.

        We completed our initial public offering on July 6, 2000, and listed our shares of common stock, represented by ADSs on the New York Stock Exchange (the "NYSE") under the symbol "MBT." Each ADS represents two underlying shares of our common stock. Prior to May 3, 2010, each ADS represented five shares of our common stock.

        In September 2001, we won a tender held by the Telecommunications Ministry of the Belarus Republic to form a joint venture with a GSM 900/1800 license to operate in Belarus. On June 26, 2002, MTS Belarus received all of the governmental approvals and licenses required to commence operations in Belarus and it began operations on June 27, 2002. In 2003 through a number of purchases we acquired a 100% stake in MTS Ukraine for RUB 11,872 million. Starting from 2007 until 2015, we operated under the MTS brand in Ukraine. In 2015, as part of our strategic partnership with Vodafone, we introduced Vodafone brand in Ukraine.

        In August 2004, we acquired a 74% stake in Uzdunrobita, the largest wireless operator in Uzbekistan, for $126.4 million (RUB 3,693 million) in cash. We acquired the remaining 26% stake in June 2007 pursuant to a put option agreement for $250.0 million (RUB 6,481 million) in cash. In May 2006, we started operations under the MTS brand in Uzbekistan. In July 2012, we suspended providing services in Uzbekistan per the order from the State Agency for Communications and Information

("SACI") of Uzbekistan on the temporary suspension of the operating license of Uzdunrobita for a period of 10 business days which was subsequently extended to three months. On August 13, 2012, the Tashkent Economic Court granted the petition of the SACI to withdraw all operating licenses of Uzdunrobita. Simultaneously various Uzbek government agencies claimed multiple violations by Uzdunrobita, which having passed through numerous court hearings resulted in heavy penalties which Uzdunrobita has been unable to satisfy. Uzdunrobita has submitted its application initiating self-bankruptcy procedures to relevant Uzbek court. On April 22, 2013, the Tashkent Economic Court declared Uzdunrobita bankrupt and initiated liquidation procedures. As a result, we lost control over the subsidiary and deconsolidated Uzdunrobita. In July 2014 the disputes between us and Republic of Uzbekistan were resolved. The parties signed the Settlement Agreement and according to its terms all mutual claims were eliminated. Furthermore, a new mobile operator, UMS, was established by governmental authorities of Republic of Uzbekistan. On September 24, 2014, an ownership interest of 50.01% in UMS was transferred to us as an incentive for reentrance into the country by the State Unitary Enterprise "Center of radio communications, radio broadcasting and television," the second shareholder of an operator, on behalf of the Republic of Uzbekistan. We started operations in Uzbekistan in December 2014. Please see "Item 3. Key Information—D. Risk Factors—Legal Risks and Uncertainties—The inability of our subsidiaries in the countries in which we are present to maintain control over their operations and assets may adversely affect our business, financial condition and results of operations" regarding recent suspension of our services in Uzbekistan and "Item 8. Financial Information—A. Consolidated Statements and Other Financial Information—7. Litigation—Uzbekistan."

        In two separate purchases in June and November 2005, we acquired 100% of BCTI, the leading wireless operator in Turkmenistan, for $46.7 million (RUB 1,343 million) in cash. Since October 2006, we have operated under the MTS brand in Turkmenistan. On December 21, 2010, the Ministry of Communication of Turkmenistan suspended our primary operating license and we ceased providing mobile telecommunications services in Turkmenistan. In August 2012, we restarted our mobile communication operations in Turkmenistan via MTS-Turkmenistan and resumed providing services for subscribers who did not cancel their contracts. Since October 1, 2012, we resumed our operations in Turkmenistan entirely and started entering into contracts with new subscribers. See "Item 3. Key Information—D. Risk Factors—Legal Risks and Uncertainties—The inability of MTS-Turkmenistan to sustain its operations in Turkmenistan on commercially acceptable terms or at all may adversely affect our business, financial condition and results of operations."

        In September 2007, we acquired an 80% stake in International Cell Holding Ltd., a 100% indirect owner of K-Telecom, the leading wireless operator in Armenia, for €260.0 million (RUB 9,142 million), and entered into a call and put option agreement initially valid until 2012 (and later extended until 2016) for the remaining 20%. K-Telecom operates in the GSM-900/1800 standard, covering the entire territory of Armenia. It historically operated under the VivaCell brand, and was re-branded as VivaCell-MTS in September 2008.

        In October 2009, we acquired a 50.91% stake in Comstar, a leading fixed line operator in Russia, from Sistema, and subsequently increased our ownership interest to 61.97% (or 64.03% excluding treasury shares) in December 2009 and to 70.97% (or 73.33% excluding treasury shares) in September 2010 through a voluntary tender offer. On December 23, 2010, the extraordinary general meetings of shareholders of Comstar and MTS approved a merger, which was completed on April 1, 2011. As a result, Comstar ceased to exist as a separate legal entity and MTS became the legal successor of Comstar in respect of all its rights and obligations.

        Prior to April 1, 2011, Comstar operated in both the Moscow and other fixed line communications markets, offering voice telephony, broadband Internet and pay-TV, operator interconnect and other services to its subscribers. As of now we still continue to provide these services. One of Comstar subsidiaries was MGTS, Moscow's incumbent fixed line operator with "last mile" access (the final phase

of delivering connectivity from a communications provider to a customer) to approximately 96% of the households in Moscow. In 2011, we completed the re-branding of Comstar with our main MTS brand. MGTS continues to provide services under its own brand.

        In 2009, we started to develop our sales and distribution network both organically and through the acquisition of several national and regional retail chains. We organized our retail operations under a wholly owned subsidiary, Russian Telephone Company ("RTC"). RTC handles all functions relating to our retail operations, including the management of points-of-sale, the purchase and sale of handsets and accessories and subscriber enrollment at our retail outlets.

        Between 2009 and 2014 we acquired controlling stakes in various regional fixed line operators as we are determined to develop broadband Internet through regional expansion.

        In April 2013, we acquired a 25.095% stake in MTS Bank for 5.09 billion rubles through an additional share issuance by the bank. As of April1, 2016 our interest comprised 26.8%.

        In December 2014, we acquired controlling stakes in Penza-GSM, SMARTS- Ivanovo and SMARTS-Ufa, operating in Penza, Ivanovo and the Bashkortostan Republic, respectively. The acquired companies hold rights to use 900 and 1800 MHz radio frequencies within the regions mentioned. The acquisition enhances our spectrum resources in the above mentioned regions. The purchase price comprised of cash consideration and a deferred payment, payable in 18 months after the acquisition date.

        In April 2014, we acquired a 10.82% stake in OZON , a leading Russian e-commerce company, through the purchase of OZON Holdings Limited's additional share issuance for RUB 2,702 million. Cooperation with OZON creates new distribution channels available to us through its extensive online retail platforms.

        In December 2015, we have completed the acquisition of NVision Group and its subsidiaries for RUB 11.2 billion. Through this transaction, we have obtained proprietary rights over our billing systems which will allow us to reduce the time-to-market for new products and better manage billing and IT-related expenses. NVision Group is also one of the largest system integrators and complex IT solutions providers in Russia.

Capital Expenditures

        We spent in total RUB 106,537 million in 2015 for network development in Russia and the other countries where we operate, which included RUB 76,671 million in cash expenditures on property, plant and equipment, and RUB 29,866 million for the purchase of intangible assets (thereof RUB 10,426 million for acquisition of 4G and 3G licenses). We expect to spend approximately RUB 87.5 billion (including 2.5 billion for acquisition of 4G licenses in Russia) in 2016 for the on-going roll out of Long-Term Evolution ("LTE") networks throughout Russia, maintenance capital expenditures, infrastructure development for our Big Data project, as well as introduction and development of network monitoring and controlling systems, further build out of 3G networks in Ukraine, replacement of outdated equipment and development of 3G networks in Turkmenistan and investments in mobile radio subsystems and supporting software products in Armenia and Uzbekistan.

        In order to achieve our goals in 2016 we are continuing to execute our "3D" strategy launched in prior year. Our new strategy envisions three areas of focus: Data, Differentiation, Dividends, and as described below, is a key to sustaining our leadership positions. The "3D" strategy expands and develops our strategic priorities and principles that we formulated in 2013.

•

Data:  we provide customers with fast and reliable networks to manage their data-driven lifestyles. We always pioneer and bring the best available technology to our subscribers, such as building high-speed 4G LTE networks which allows us to be one step ahead of ever growing demand for data consumption. Our commercial strategies are focused on increasing data penetration. We ensure customers have the best possible connectivity experience at their homes, workplaces and places in between.



•

Differentiation:  as a multiservice operator, we leverage our retail network to engage customers with products and services to enhance their digital lives. We have established Moscow as world-class city in terms of connectivity and network access, and anticipate customer needs through a diverse portfolio of products and services to meet a world beyond communications.



•

Dividends:  we continuously improve the operational efficiency of MTS. We further develop the organizational capabilities of MTS, constantly work on organizational effectiveness, and keep it responsive to market challenges and customer needs. We sustain high levels of business profitability and aim to enhance shareholder returns.

        Implementation of the strategy is subject to a number of risks. See "Item 3. Key Information—D. Risk Factors" for a description of these and other risks we face.

Automatic Roaming

        Roaming allows our customers, both subscribers and guest roamers, to receive and make international, local and long-distance calls while traveling outside of their home network. Roaming is provided through individual agreements between us and other GSM operators. Unlike many non-GSM providers that require additional equipment or prior notification, our roaming service is instantaneous, automatic and requires no additional equipment.

        As of December 31, 2015, we had bilateral roaming contracts with 784 wireless operators in 228 countries, including 16 regional operators in Russia. We continually seek to expand our roaming capability and are currently in negotiations with additional operators.

Value-Added Services

        We offer various value-added services to our customers. These services may be included in the tariff plan selected by the subscriber or subscribers may pay additional monthly charges and, in some cases, usage charges for them. Some basic value-added services that we offer include:

        We also provide many voice and SMS-based value-added services in cooperation with various content providers.

GPRS, EDGE services

        We launched our commercial 2G network in 1994 based on GSM-900 technology. From 1999, we significantly improved our 2G network capacity based on GSM- 1800 technology. From 2001, we implemented wireless data communication services based on GPRS technology with download data rate up to 85.6 Kbit/s. In 2005, we modernized our GSM network to support EDGE technology and tripled data services rates. Today we continue supporting and modernizing our 2G network and we put the prime focus at the development of our 3G and LTE networks in order to provide our subscribers with high-speed broadband wireless services. As of December 2015, we provided GSM, GPRS and EDGE services with nearly 37,000 2G sites over the geographic area with more than 94% of population of Russia.

3G Technology

        In April 2007, we received a nationwide 3G/UMTS (Universal Mobile Telecommunications System) license in Russia. The license is valid through 2017 and covers the entire territory of Russia with frequencies 1950-1965 MHz and 2140-2155 MHz. We currently have commercial 3G networks launched in all regions of Russia with the exception of Crimea. By the end of 2015, we installed 37,199 3G sites throughout Russia.

        Together with 3G networks in Armenia, Belarus, Turkmenistan and Uzbekistan and since October 2015 in Ukraine, we operate more than 42,000 3G sites. We have also obtained a permit to use the UMTS 900 standard in Moscow region and Habarovskiy kray. As of December 31, 2015, our UMTS 900 network consisted of 1,980 sites.

        Starting from 2010, we implement HSPA+ technology, which supports up to 21 Mbit per second data transmission speed. In addition, we launched second and third 3G carriers to improve capacity and activated Dual Carrier technology, which supports up to 42 Mbit per second data transmission speed in more than 33,700 sites in Russia.

        Since 2011 we use 3G femtocell network. Femtocells are small low-power wireless base stations in the licensed 2100 MHz spectrum. They connect to a mobile operator's network using residential DSL or cable broadband connections and can support multiple standard mobile devices. Femtocells deliver a strong signal and high-quality voice service to standard mobile devices in homes, small and large offices, outdoor public spaces, metro hotspots and rural areas. A femtocell network also provides for high speed of data upload and download. The total number of femtocells installed in Russia reached 4,234 by the end of 2015.

        We commenced commercial services using CDMA 450 technology in Ukraine in November 2007. In July 2012, we launched Rev B CDMA technology services in the Kiev region and offered high-speed mobile Internet access to our subscribers throughout Ukraine. Following the massive launch and subsequent expansion of UMTS services, we plan to take a decision on the future phase out of CDMA 450 network in 2016.

        In February 2015, we obtained UMTS spectrum in 2100 MHz band in Ukraine through an open tender held by the National Commission for the State Regulation of Communications and Informatization. Upon completion of critical network upgrades, we started providing our own 3G services in major Ukrainian cities under the Vodafone brand starting from October 2015. HSPA+ (QAM64 and Dual Carrier) technology, which is available in our 3G network from the start, allows to download speeds up to 42 Mbit\s. As of the end of December 2015, our network consisted of about 3,000 UMTS-2100 base stations and MTS was providing 3G services in 19 regional centers throughout

Ukraine. We are planning a significant expansion of 3G network coverage, including indoor coverage, as well as network capacity upgrades in 2016 and later to satisfy license requirements and meet increasing market demands.

        In October 2007, K-Telecom, our subsidiary in Armenia was allocated frequencies to offer 3G services throughout the entire territory of Armenia. The frequencies were allocated for a 10-year period. In 2009, we commercially launched our 3G network in Armenia. In 2011, K-Telecom started to provide telecommunications services based on HSPA+ technology in Yerevan, six northern regions and in some southern regions of the country. As of December 2015, HSPA+ technology with QAM64 and Dual Carrier features is available throughout 98% of the Armenian inhabited area. In 2015, we launched 90 new sites with SingleRAN 2G/3G base stations. We are currently implementing an all-IP concept by providing IP interfaces and transmission link for all base station sites, which is the basic approach for future LTE networks. In 2016, we will further expand 3G network coverage and capacity, implementing small cell and multi beam antenna solutions.

        In Turkmenistan, we currently provide services based on 3G services with HSPA+ technology for business and private customers in all regional centers throughout the country. In 2015, we launched 49 3G base stations. However, due to lack of required Internet channel bandwidth which we lease from the state-controlled telecom service provider we had to suspend our 3G network expansion plans until the issue is resolved.

        In 2014, we started replacing outdated radio access network with SingleRAN technology, while providing IP interfaces and transmission links. In 2015, we continued upgrading our 3G network to HSPA+ technology in Tashkent. Major network modernizations, which include full scale capacity upgrades in Tashkent and in the regional centers, as well as new coverage radio access infrastructure in regions, will come into effect in 2016. We are also planning transmission network upgrades to implement IP-based technology and ensure higher capacity satisfying growing data traffic demand.

LTE Technology

        In July 2012, the Russian Ministry of Communications and Mass Media announced the results of a tender for national-wide LTE-FDD frequencies. MTS is among the four companies, including Rostelecom, MegaFon, and VimpelCom which obtained LTE-FDD frequencies in 700, 800 and 2600 MHz bands.

        In September 2012, we began offering LTE-based commercial services in Moscow region.

        In 2014, we started DCS 1800 spectrum refarming to LTE and rolled out LTE-1800 network, while expanding LTE 800/2600 coverage. As of December 31, 2015, we had 17,087 LTE sites in 83 regions of Russia. In 2016, we are going to further roll out LTE 800, 1800 and 2600 MHz frequency bands and implement LTE-Advanced with Carrier Aggregation and Voice over LTE services.

        In Yerevan, the capital of Armenia, we commenced a commercial test of the first 4G/LTE network in December 2010. Since 2014, we provide full LTE outdoor coverage for two major cities—Gyumri and Vanadzor and expand LTE coverage in Yerevan. Circuit Switch Fall Back (CSFB) functionality is available to all our LTE subscribers.

        In 2015, we started upgrading our network in Tashkent (Uzbekistan) for planned launch of LTE FDD commercial services in 800 MHz frequency band along with hot spots LTE 2600 coverage and trial launch of Carrier Aggregation technology during 2016.

networks capable of interconnecting with fixed line operators, installation and maintenance of cellular payphones, lease of digital communication channels, access to open computer databases and data networks, including the Internet, and provision of fixed, local and long- distance telecommunications services, as well as video conferencing.

Strategic Partnership with Vodafone

        In October 2008, we announced a strategic agreement with Vodafone aimed at drawing on Vodafone's expertise in building and developing 3G networks and mobile broadband products, working with leading global equipment providers and deploying innovative client relationship management ("CRM") practices to enhance quality and further improve the efficiency of our operations. In addition, the agreement allows us exclusive access to a range of products, services and devices from Vodafone for our markets of operation in Russia, Ukraine, Turkmenistan and Armenia.

        In 2015, the Group extended its strategic partnership agreement with Vodafone to introduce the Vodafone brand in Ukraine. Under the new partnership, MTS Ukraine and Vodafone plan to roll out 3G networks and to develop a number of new services, which have proved extremely popular in Europe, including bundled offers, competitive long-distance international calls and worry-free roaming when abroad, in the Ukrainian market. Other areas of cooperation remain in full force.

Sales and Marketing

Target Customers

        Our service model is based on the provision of services to differentiated levels of customers to meet the needs of distinctive customer segments as such segments have developed. Today, we are considered a mass-market mobile network operator with a wide range of subscribers in all customer segments. However, we are constantly expanding our brand eco-system which now also includes our fixed broadband business, satellite TV branch as well as banking and financial services division. As part of our core business strategy, we provide a wide range of products and services to various customer segments.

        In 2015, we continued our initiatives targeted at increasing mobile broadband user base, developing value added mobile internet services and strengthening our leadership in data by widening our 4G LTE coverage and perfecting the quality of our high-speed 4G internet. In terms of products, we shifted our focus from user-switchable data options towards package deals integrating both voice and data (the Smart tariff plans line).

Table of Contents

        In order to build brand awareness and stimulate demand we use a combination of various advertising formats, including television, outdoor, newspaper, magazine and radio. Increasingly, we also advertise on-line and in mobile (with the help of traditional as well as innovative and novel projects) to market and promote our products and services to the broad audiences of current and potential customers. Additionally, our indirect advertising includes sponsorship of selected television programs, sport events, music shows and other popular events. We also coordinate the advertising policies of our dealers and partners, such as MTS Bank, to capitalize on the increased volume of joint advertising and preserve the integrity and high-quality image of the MTS brand.

        To support our key directions we undertook the following initiatives in 2015 in Russia and in selected other countries in which we operate:

Brand and New Positioning

        One of the major milestones for MTS in 2015 was the development and launch of the new brand positioning. In line with the new brand philosophy, MTS views the world as a universe of opportunities, believes in the potential of every person, and delivers technology, products and services, which help our customers face today's world challenges, achieve ambitious goals and realize their true potential. The new positioning is now supported with a new tagline, "You Know That You Can," as well as our new visual style, which symbolize the transcend of limitation, boldness and authenticity thought the use of dynamic craft-style visuals instead of confined digital-style stylistics we used in previous years.

        The launch of the new positioning was supported by an image-building advertising campaign entitled "Manifest," which included various media channels, such as TV, digital, cinemas, indoor. Additional special projects implemented throughout the year increased the overall effect of the launch campaign and ensured positive feedback from all audiences.

        Hero Stories—A special online project with inspirational stories from the lives of celebrities and public figures about their challenging paths to success and determination to achieve their goals.

        Dance on TNT sponsorship—To support our new positioning launched in May 2015, we initiated a productive cooperation with a major entertainment TV channel in Russia, TNT, and its super popular TV Show—"Dance on TNT." Together, MTS and TNT launched a multimedia campaign based on the theme of the show. We organized dancing master classes and concerts as well as provided everyone with an opportunity to perfect their dance moves through watching a dedicated (and "mobile first") video series specially produced by MTS and TNT and available on every smartphone in the country. We addressed all the viewers of the show and made them believe that they can learn to dance.

        The Power of the Slogan—To let everyone get a feeling of our new tagline, we created a website inviting our users to tell their own stories of success, help others get inspired or share their own slogans across social networks. The viral nature of the project helped us further increase awareness and mass popularity of the new slogan.

Network Quality (4G u HD-Voice)

        Network quality has always been one of our key priorities and an important attribute influencing net-promoter score of the company. We constantly strive to improve the quality of our network, we continue to develop the infrastructure and implement new technologies. To maintain and improve the perception of our network quality we continued communications support for our high-speed 4G LTE mobile internet as well as HD quality voice service through advertising campaigns and localized and targeted placements to amplify the high-quality message.

4G LTE Network support

        In 2015, we continued our efforts in rolling out 4G LTE network across the country. As of April 1, 2016, MTS 4G high-speed broadband network has been deployed in 83 out of 85 regions in Russia. Obviously, as in previous years we supported the roll-out with active regional advertising campaigns, which stimulated additional interest to our mobile internet services and desire to switch to 4G compatible devices.

Smart tariff plans

        In 2015, we proceeded to communicate the benefits of Smart voice & data (V&D) tariff plans as a key focus in our product strategy and launched a new unlimited tariff plan—Smart Nonstop. This new tariff plan was targeted primarily at the digital-generation youth audience and proved to be quite revolutionary on the market. In our advertising campaign we played an insight that even though current youth "lives" online, significant part of the internet audience is passive in terms of content consumption. With our "You Know That You Can" attitude we decided to change this situation and through the #MakeYourInternet (in Russian) hashtag as well as special mobile applications encouraged people to be active and energetic and generate more content of their own.

Internet on All Devices

        In 2015, we launched a new product for the market—Unified Internet. This service allows customers to use a single mobile internet package and split or share it with other devices they own, maintaining a simple and user-friendly way to control their traffic consumption on smartphones, tablets, modems, etc.

Mobile payment and financial services

        The financial world is changing at a great pace. We understand the trends and pioneer various mobile financial services on the Russian market. In 2015, we further strengthened our positions on the mobile payment arena and conducted a dedicated marketing campaign related to numerous ways to transfer money currently available at MTS: from simple peer-to-peer SMS transfers to mobile apps and cash transfers at MTS offices around the country.

        We are very active in pushing forward innovative technologies such as NFC payments. In several cities in Russia, including Moscow, one can now pay for subway (metro) with a simple touch of their phone equipped with an MTS SIM-card. In 2015, MTS was also one of the major participants of the NFC Forum held in Moscow and will continue being on the front edge of mobile payments and financial services in the years to come.

        Another important step in 2015 was that we decided to fully integrate our banking branch, MTS Bank, into our unified MTS brand eco-system. From now on, all financial services will be offered and communicated under the parent umbrella MTS brand and will use the same visual style as all other MTS communications.

Regional platforms for Moscow and St. Petersburg

        In order to strengthen our business and brand positions in Moscow and St. Petersburg, in 2014 we created special communication platforms for Moscow and St. Petersburg taking into account the specifics of these regions and their citizens.

        In 2015, we continued active implementation of these local strategies with multidimensional and multimedia projects, such as MTS #WOWMOSCOW (for Moscow) and The Culture Capital (for St. Petersburg). Through grants to small businesses, massive music concerts and art-related projects as well as special TTL campaigns such as 4G LTE Taxi, we have shown our active involvement in

supporting and developing local communities and providing added value to these major cities in Russia once again.

Devices

        In 2015, we and our retail network introduced a revolutionary offer and significantly decreased prices on all devices to further push the proliferation of smartphones and tablets and stimulate user transition from feature phones to data-consuming devices. Thus, the majority of devices-related communications campaigns were targeted at supporting the key message of the best price on new devices, especially 4G-enabled smartphones. Most of these campaigns were developed and implemented in cooperation with major device vendors such as Samsung, Huawei, etc. as well as Google. Through integrating "OK, Google" theme in our advertising, we were able to more effectively communicate the use cases and benefits of switching to smartphones.

Intranet roaming

        In summer 2015, we launched a strong campaign to build a knowledge that we cancelled additional fees for roaming across Russia. Russia is a vast and beautiful country with endless possibilities for travelling. In our campaign, we showed the country in such a way so that audience would wish to travel to different places in Russia and through the use of no-roaming-fee service from MTS to share their discoveries with friends and family.

Business to business offers

        In 2015, we retained and strengthened our leadership in the corporate market via launching a full-scale image campaign across various communication channels, including TV, radio, online, print, airports, business centers. The advertising campaign did not simply say "we are the best" but featured our major corporate clients who talked about their experience working with MTS. Our clients, the leading companies representing various businesses (Aeroflot, Raiffeisenbank, TASS, Gulfstream security systems, INTOUCH Insurance), let us showcase their internal processes based on the MTS products and explain how these solutions help them grow.

        Another initiative was a series of video case studies with various corporate clients from different industries which were broadcasted on the major business TV channels in the framework of the Business with High IQ series where MTS' clients shared their experience in implemented tailor-made telecom solutions provided by MTS.

Other products and services

•

In Moscow we continued to communicate the benefits of the GPON technology (the fastest fixed broadband in Moscow through optic cable) which allows us to provide highest-quality Broadband and TV services. In other regions with more sensitivity to pricing, we applied a more relevant "value for money" strategy.



•

In 2015, we also made a special emphasis on TV service in our communication of residential offerings, and launched a federal campaign, Total TV, in which we established ourself as the first provider to offer all possible TV services, including digital, mobile and satellite, thus providing our customers with an opportunity to enjoy their favorite TV programs and shows from any device.



•

Summer of the 2015 saw the launch of the MTS satellite TV, resulting in a full-scale campaign which highlighted the advantages of the "smart satellite dish" which allows customers to manage their viewing through pause, record and rewind functions.

At the end of 2015, to help Father Frost (Russian Santa Claus) spread season's greetings, we gave him the most advanced technologies and tools, thus becoming the official mobile operator of the Father Frost. Father Frost's website was given a revamp, enabling its visitors to learn more about Father Frost's official residence in Veliky Ustyug, to participate in contests and create a New Year gift cards. Visitors to Father Frost's domain in Veliky Ustyug, Votchina, were provided with an opportunity to use an interactive mobile app developed by MTS specially for the holiday season.

Global recognition

        In 2014, MTS was included in the BrandZ™ Top 100 Most Valuable Global Brands 2014 ranking for the seventh consecutive year, as well as being recognized as the most valuable Russian telecom brand and made it to top 10 leading telecommunications brands in the world.

Sales and Distribution

        We have historically enrolled the vast majority of our subscribers through a network of independent dealers that operate numerous points-of-sale in places with high consumer activity, such as supermarkets, shopping centers, transportation hubs and markets. In 2009, in response to changes in the independent retail market, we began to develop our own proprietary retail network to more effectively control sales of SIM-cards and provide a platform to sell sell handsets and accessories. We organized our retail operations under a wholly owned subsidiary, RTC. RTC handles all functions relating to our retail operations, including the management of points-of-sale, the purchase and sale of handsets and accessories and subscriber enrollment at our retail outlets. It also requires us to secure optimal locations for our points-of-sale and monitors the effectiveness of their operations.

        At the same time, in 2010, we focused on improving cooperation with a certain few of the large national and regional mobile handset retailers, such as Euroset and Svyaznoy, through which we had previously sold our products and serviced. In 2009, VimperlCom acquired a minority stake in Euroset, while in 2012, its ownership structure changed to accomodate an investment by Megafon, which equalized ownership with VimpelCom at 50/50. Throughout 2013 Euroset prioritized sales of its owners at the expense of MTS which impaired our ability to attract higher-quality subscribers and impacted profitability. Thus, MTS terminated its agreement with Euroset in May 2014.

        In 2013, we entered into an agreement with Svyaznoy to distribute SIM-cards and our sales through its outlets increased significantly during the year. We also continued to develop our monobrand retail chain, and in 2014, we could boast of attracting over half of our subscribers through our own proprietary distribution network. In 2014, Svyaznoy was the second in sales volume among MTS sales channels. In November 2014, Svyaznoy experienced changes in its ownership which led to the deterioration of MTS sales and an increase in competitors' sales beginning April 2015. While volumes declined throughout 2015, as of August 2015, MTS entirely ceased sales at Svyaznoy outlets. MTS designed a range of activities including the development of proprietary distribution network and stimulation of sales growth in regional distributors channel to compensate for the losses in subscriptions and achieve sales targets. We now realize over 65% of our SIM-card sales through our own monobrand retail chain while our retail arm is an increasingly important component of our differentiation strategy and ability to offer affordable handsets and accessories to our customers. See "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Business—Our failure to further develop and sustain our distribution network as well as the reduction, consolidation or acquisition of independent dealers may lead to a decrease in our subscriber growth rate, market share and revenues."

        In 2015, we continued to implement our strategy in retail operations by increasing the efficiency and optimizing the structure of our proprietary sales and distribution network. We expect to continue

enhancing the efficiency and structure of this sales network, including through the optimization of points-of-sale locations, with the aim of maintaining our market position.

        Our proprietary distribution network consists of MTS-branded franchise points-of-sale (third-party dealers operating under the MTS brand) and MTS-branded points-of-sale owned by us. As of December 31, 2014, we operated 4,245 points- of-sale, including 1,326 franchise points-of-sale and 2,919 points-of-sale owned by us.

        In 2015, we have been focusing on the development of the structure of our proprietary network in Russia. As of December 31, 2015, we operated 5,133 points- of-sale, including 1,681 franchise points-of-sale and 3,452 points-of-sale owned by us.

        For newly acquired mobile subscribers in Russia, we link commissions payable to a dealer on a monthly basis to the amount of revenues we receive during six- to 12-month period from the date a subscriber is activated by a dealer. In addition, we have established caps, or a maximum commission amount payable to our dealers. The dealer commissions in Russia currently range between RUB 80 and RUB 1,920 per subscription.

        In Ukraine, we link dealer commissions to the tariff package sold, category of subscriber, subscriber revenue, the duration of a subscriber being active, city of subscription and status of the specific dealer. We have different commission structures based on whether the subscriber is Prepaid, Postpaid or a CDMA-only subscriber (i.e., subscribers using only mobile Internet services). For each new subscriber, a dealer typically receives a one-time commission payment at the time the contract is signed or monthly payments based on the revenue generated from the subscriber. The dealer commissions in Ukraine for Postpaid tariffs consist of one-time commissions of RUB 121 to RUB 146, that depends on the region of activation and we are entitled to retain the full commission amount if the subscriber stops using our services within five months following the month of activation. In addition, we may also pay monthly commission in an amount ranging from 30% to 36% of the revenues generated by the subscriber for a period from 6 to 12 months depending on the region of activation and dealer's plan achievement. Prepaid tariff commissions for activation of a subscriber are linked to the territory where a dealer operates. The period during which we pay a dealer commission depends on our market share in that territory and may vary from 4 to 10 months, and equals to the amount of 50% of the subscriber's monthly invoice. We also pay monthly dealer commissions of RUB 304 for high quality, long-term subscribers, as well as a lump sum amount of between RUB 6,984 and RUB 63,771 to exclusive dealers who sell exclusively MTS Ukraine products and services. For CDMA subscriptions, we typically pay dealers a one-time fee of RUB 152 upon subscriber activation, as well as monthly payments up to 12 months based on the revenue generated by the subscriber.

        We believe that our method for paying commissions provides dealers with greater incentives to add new subscribers, reduces the risk of dealer fraud and improves our cash-flow management.

Competition

The Russian wireless telecommunications market

        Demand for wireless communications services in Russia has grown rapidly over the last 10 years due to rising disposable incomes, increased business activity and declining prices due to intensified competition among wireless communications providers. As of December 31, 2015, overall wireless penetration in Russia was approximately 171.9%, or approximately 252 million subscribers, according to our estimates.

        The primary mobile competitors in Russia include us, MegaFon and VimpelCom, each of which has effective national coverage in Russia. Competition is based on network coverage and quality, the level of customer service provided, roaming and international tariffs, local tariff prices and the range of services offered. For a description of the risks we face from increasing competition, see "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Business—We face increasing competition in the markets where we operate, which may result in reduced operating margins and loss of market share, as well as different pricing, service or marketing policies."

        The following table illustrates the number of wireless subscribers for each network operator in Russia as of December 31, 2013, 2014 and 2015:

        MegaFon.    MegaFon, which operates GSM 900/1800, UMTS (3G) and LTE (4G) networks, is one of our primary competitors in Russia, and it is the second largest GSM wireless operator in Russia in terms of subscribers. According to AC&M-Consulting, MegaFon had a subscriber base of approximately 74.8 million subscribers in Russia, which represented a 30% market share as of December 31, 2015.

        VimpelCom.    In addition to MegaFon, we also compete with VimpelCom, which is the third largest GSM 900/1800/UMTS (3G)/LTE (4G) wireless operator in Russia in terms of subscribers.

        T2 RTK Holding.    In February 2014, Tele2 and Rostelecom announced a merger which created a new federal operator. The license portfolio of the new company covers each region in Russia which effectively permits the roll out of federal-scale networks. Although the operator lacks GSM 900/1800 or 2G frequencies in Moscow and Moscow region, the operator possesses sufficient frequencies to roll out 3G and 4G networks in each federal region, including Moscow. By the end of 2015, the number of regions penetrated by combined operator exceeded 60. According to AC&M-Consulting, Tele2 had a subscriber base of approximately 37.3 million in Russia and 15% market share as at December 31,

        Other Operators.    The number of subscribers of other operators is about 2.7 million customers as of December 31, 2015.

The Ukrainian wireless telecommunications market

        The history of mobile communications in Ukraine began in 1993. The first company in the mobile market of Ukraine was UMC (Ukrainian Mobile Communication), afterwards it became MTS Ukraine. In 1997, the mobile operator Kyivstar launched services under GSM 900/1800 standard. While Astelit, another GSM 900/1800 standard operator and joint venture between Turkcell İletişim Hizmetleri A.Ş. and local Ukrainian shareholders, began operations in 2005. The two largest wireless telecommunications providers in Ukraine (in terms of subscribers) are MTS Ukraine and Kyivstar sharing 78% of the market, with 43% and 35%, respectively, as of December 31, 2015, according to AC&M-Consulting.

        In Ukraine, we compete primarily with Kyivstar, which boasts approximately 25.4 million subscribers as of December 31, 2015. Kyivstar offers wireless services using GSM 900/1800 and UMTS technologies under the "Kyivstar" brand and fixed line services by the fiber-to-the-building technology ("FTTB") under the brand "Kyivstar Home Internet." Astelit offers services in GSM 900/1800 and UMTS standards under the "lifecell" brand.

        On February 23, 2015, three of the largest mobile operator of Ukraine, including Kyivstar, MTS Ukraine and Astelit took part in the 3G license tender. MTS Ukraine won in a tender the second lot offered which included the use of 1950-1965/2140-2155 MHz frequency bands.

        MTS Ukraine was the first company that provided its subscribers with an opportunity to use 3G Internet through cooperation with 3mob, a local UMTS operator owned by Ukrtelekom, a formerly state-owned telecommunications firm which historically operated Ukraine's legacy PTSN networks. All operators have launched new 3G tariff plans aimed at data consumption growth.

        On October 5, 2015 Telenor Group announced its intention to sell its shares of the Dutch company VimpelCom including its Ukrainian subsidiary mobile operator "Kyivstar."

        On October 15, 2015, MTS Ukraine signed a branding agreement with Vodafone Group on the use of the Vodafone brand for corporate communications, the rebranding of service centers and points of sale as well as 3G-enabled products and services. The first tariff plans under a new brand—Vodafone Red—became available to the Ukrainian subscribers in November 2015. The main differentiator of these packages is affordable communication in roaming and international calls combined with mobile internet access.

        On November 11, 2015, the Cabinet of Ministers of Ukraine approved the plan of measures for implementation of 4G communication in Ukraine. According to this plan, the operators will be able to launch 4G in the second half of 2017.

        Despite the ongoing political and economic crisis as well as complex and unpredictable situation in the eastern Ukraine, our subscriber base increased slightly in 2015 by 0.2 million subscribers. Our average price per minute (APPM) decreased by 5% RUB (increased by 10% UAH) YoY in 2015. ARPU decreased by 11.5% RUB (increased by 2.3% UAH) and MOU decreased by 8.3% YoY (using the official average monthly rate, refined approach to the calculation of the average annual subscriber base).

        Overall wireless penetration in Ukraine in 2015 decreased to 137.3%, or approximately 58.7 million subscribers, as compared to 138.2%, or approximately 59.3 million subscribers, in 2014, according to our estimates.

Tariffs

        We customize our marketing efforts and pricing policies in each region of Russia and our other countries of operation by considering such factors as average income levels, the competitive environment and subscriber needs, all of which vary from region to region.

shows the mix between Prepaid and other subscribers, such as contract and corporate customers, for Russia and Ukraine for the periods indicated:

        We are seeking to migrate our customers from advance payment plans to credit payment plans in an effort to stimulate ARPU and reduce churn. We endeavor to mitigate the risk of bad debt through the implementation of credit scoring algorithms that assess and help manage the risk of potential bad debt.

        We currently have a unified system of tariff plans offered to subscribers throughout Russia. The unified system is aimed at achieving such benefits as clarity, simplicity and transparency for prospective subscribers by offering the same set of tariff categories throughout Russia. Under each tariff category, we offer different tariff plans with different connection fees, per minute call charges and a wide range of value-added services.

        By advertising on a national rather than regional or local level, we have been able to streamline and reduce our advertising and marketing expenses through unified advertising campaigns throughout Russia. Furthermore, we are able to convey to consumers a more uniform perception of our brand and services.

Tariff Plans in Russia

        Currently, each of our tariff plans in Russia combines per minute usage charges, value-added services in packages and different monthly network access fees (with the exception of the prepaid tariff plans) designed for different market segments. Our tariff plans are designed to be simple and appeal to particular segments of the market taking into account such factors as customer needs and consumption levels. Our tariff plans are currently divided into five categories—"Prepaid," "Smart," "Unlimited," "Data" and "Corporate"—with each category designed to target specific segments as follows:

•

Prepaid:  Prepaid tariff plans are geared towards consumers who use their mobile phones for personal communication. These plans do not have monthly subscription fees and the per-minute fee charges depend largely on the tariff plan chosen. We offer a family-oriented tariff plan, "Super MTS," which allows family members to make up to 20 minutes of calls per day within the network for free. The "Super MTS" tariff plan varies depending on the region of the customer and it is a tariff plan which we believe will remain a competitive tariff plan over a long period of time. We also offer a tariff plan, "Red Energy," developed for different market segments, featuring flat price for calls within our network and calls to other networks. Subscribers to our prepaid plans can reduce the price of their calls by using tariff options which have a subscription fee. After our customers subscribe to a particular prepaid plan, they have the option of switching to a different prepaid plan by sending an SMS message (USSD request) to a designated number.

The "Simply Super" tariff line offers a set of services on a Pay-Per-Use (PPU) basis without fixed daily payments, it is daily limited in net minutes' package and daily GPRS internet use is not limited. All regions are grouped into several clusters depending on the population and region's potential. Special terms are based on the tariff "Simply Super" but with price differentiations and volumes of free minutes within the network, prices for other mobile operators and cheaper data prices.

        As of December 31, 2015, the standard per minute tariff for calls to mobile network operators in Ukraine varied from RUB 1.06 per minute to RUB 4.56 per minute. Tariffs for calls to fixed lines in Ukraine varied from RUB 1.51 per minute to RUB 4.56 per minute. The standard per minute tariff for calls within the MTS Ukraine network ranged from RUB nil per minute with limitations in minutes per day or month to RUB 3.04 per minute. International tariffs ranged from RUB nil per minute for calls to some countries in tariffs under Vodafone brand within bundled minutes in Vodafone Red tariffs to RUB 258.12 per minute in standard international tariffs for satellites. All tariffs for MTS Ukraine subscribers are quoted in hryvnias. The tariffs set forth above are translated from hryvnias to Russian rubles using the official exchange rate of 0.33 hryvnias per RUB 1 as of December 31, 2015.

Customer Payments and Billing

        We enroll new prepaid subscribers in an advance payment program, under which the subscriber prepays a specific amount of money to use our services. As of December 31, 2015, 85% of our consolidated subscriber base was enrolled in the advance payment program and 15% used a credit based system.

        Our advance payment system monitors each subscriber account and sends an advance warning on the subscriber's mobile telephone when the balance on the subscriber's account decreases below a certain threshold.

        Under the credit payment system, customers are billed monthly in arrears for their network access and usage. We limit the amount of credit extended to customers based on the customer's payment history, type of account and past usage. As of December 31, 2015, subscribers using the credit system of payment had credit limits of up to RUB 98.02 million for key corporate customers in Russia. When

99

a credit limit is reached, we block the telephone number until the balance is settled. There are no credit limits established for certain exceptional, high loyalty customers.

        We provide "in full confidence" service, which allows our Prepaid customers who subscribe to this service to continue using services when the balance on the subscriber's account becomes negative. As of December 31, 2015, subscribers using the "in full confidence" service had a maximum credit limit of RUB 28.7 thousands. Customer service representatives can set individual credit limits for subscribers based on their payments and charge history (i.e., average balance usage) during the prior three months. When the credit limit is reached, our billing system blocks the phone number until the balance is settled. Similar to the credit payment system, the subscribers are billed monthly in arrears for usage. The invoice, which can be delivered to the customer by e-mail, fax, regular post and Internet, should be settled within 24 days. If the invoice is not paid five to seven days prior to the due date, the system sends an additional reminder. The telephone number is blocked on the 25^th day if the invoice is not settled.

        In Russia, we offer our subscribers various ways to pay for our services, including cash or credit card, wire transfer, prepaid cards and express payment cards.

        We implemented Foris billing system in Russia in 2008. The Foris billing system allows us to offer all of our subscribers a uniform and consistently high level of service. It also supports the monitoring of account usage in real time. In addition, the system provides us with the ability to offer flexible tariff plans with various usage discounts and subscriber loyalty bonuses. Furthermore, we are able to provide our corporate subscribers with more sophisticated customized billing solutions. For example, our corporate subscribers who use multiple phone numbers in different regions of Russia now receive a single invoice, whereas our previous billing system could not support such a service.

        In Armenia, we use the "Eskadenia" billing system.

        In Ukraine in 2015 we completed migration of all our Postpaid customers accounts to the Foris billing system, which resulted in more opportunities in optimization of the billing process and provided services.

        In Ukraine, our Postpaid corporate and high-end subscribers receive an invoice which must be paid by a specified date. If the subscriber fails to pay, we block the phone number until the balance is settled. Our contract subscribers, who make an advance payment, are able to continue using our services once they reach a zero balance or until their accounts reach the credit limit specified in their service agreements. When the limit for such a subscriber is reached, we suspend our service until the balance is settled. We determine account terms and credit limits for each subscriber based on the subscriber's account age, payment history and tariff plan.

        In Ukraine we provide services to our Prepaid customers for as long as the balance on their accounts remains above zero and/or the tariff plans allow to use free-of-charge services without having the positive balance on the account.

        In Ukraine we offer our subscribers various ways to pay for our services, including cash or card payment at the cash desk of the bank, through the recharge terminals, bank transfer from the current account (for legal entities), via internet and payment card of fixed nominal value.

Customer Service

        In order to attract and retain customers, we must ensure a high level of service at all points of customer assistance, care and billing. In each region where we operate, we have contact centers that provide customer service 24 hours a day, seven days a week. Contact centers provide different services to our clients through various channels (telephone, email, online and fax). Customer service representatives respond to various issues such as phone lock due to lack of payment, handset operation,

roaming capabilities, service coverage and billing. A particular group of customer service representatives handles customer complaints and helps those who want to change their service terms. We use automatic systems and independent analysis for monitoring availability and customer satisfaction level of service in our contact centers regularly. We conduct outbound campaigns with the assistance of our employees in the outbound contact center and the laboratory of the customer relationship management inasmuch as we need to improve customer loyalty and promote our services.

        In 2015, our back-office has significantly improved its performance: some requests began to be fulfilled more than twelve times faster. In addition, processing time for the requests of corporate customer segment decreased by four times. The work of the monitoring group of the Internet is centralized, we increased the number of employees in this area, which allows us to react quickly to a myriad of comments about MTS service in Internet.

        A set of procedures has been streamlined for mobile business customers. A new IVR scheme (interactive voice response) was implemented with various connection options with a specialist: a paid expectation on the line, free expectation and ordering a callback. The scheme was applied in all regions of the Russian Federation for highly profitable customers (except Moscow and St. Petersburg). "Marketing IVR" service was implemented within MTS. While calling the Contact Centre, customers are invited to take advantage of offers of the company which correspond to their needs in the consumption of voice and data traffic. In December 2015, the service was launched for customers of the central region of Russia.

        Maintenance of key customers of fixed line business has been consolidated within the contact center. All key fixed-line customers can now get expert help and advice over the voice channel, or via e-mail. In 2015, sales and service of new products for customers was launched: satellite TV, interactive TV, video monitoring (for MGTS clients) and convergent product.

        The total number of customer complaints relating to technical failures within the network decreased by 9% year on year due to increase of efficiency of such failures handling, automation systems for monitoring customer complaints in the CRM and other measures. Currently, if there is a technical failure causing a decrease in the quality of services, MTS necessarily informs about such failures via SMS, thereby eliminating the application of a customer with the same problem.

        In 2016, we plan to develop new services based on speech recognition for our clients, engage the process of reducing the number of calls into the contact center and increase the percentage of customers solved problems.

        In Ukraine we made the customer assistance process more personalized by anticipating customer needs. We have enhanced the quality of our customer service as a result of the complete integration of our IVRs and billing. We have improved IVRs menu that enhance its utility. We continued to work on the improvement and expansion of self-service channels for subscribers. As part of online "self-service," we continued developing "self-care" functions through the web and IVRs (which provide, among other things, details of the subscriber's account, tariff plan specifications, amounts charged on credit cards, management of on-line service and charge details for contract subscribers). We also developed special services, such as shortened phone numbers, for broadband users and premium customers who require assistance. We increased the number of services available to our customers in contact centers. We have a mobile version of the Internet Helper for smartphones. In 2013, we launched a new mobile application for Android OS. The application allows users to manage their account directly from their smartphones.

        In 2015, we continued to develop our operational CRM system. As a part of this process we have migrated contact center from local network to cloud technologies. We started user friendly customer service in contact center, whereby we were awarded with a Gold Medal for Best Customer Service in the ContactCenterWorld—The Global Association for Contact Center & Customer Services. We have

also launched gifts for customers waiting at IVR before connection with contact center representative. Start of operations under Vodafone brand caused great impact on customer service from 4th quarter of 2015 and will continue to have an even greater influence later.

        In 2016, we plan to improve software and hardware for contact center, implement operational CRM and introduce new knowledge base for internal users. We are going to develop VIP customer service for private segment. We will run cross platform mobile application. As for customer service, we will continue to work on simplification of processes, procedures and KPI's.

Network Technology

        We launched our commercial 2G network in 1994, based on GSM-900 technology. From 1999 we significantly improved our 2G network capacity on the basis of GSM-1800 technology. From 2001 we implemented wireless data communication services based on GPRS technology with download data rate up to 85.6 kbit/s. In 2005 we modernized our GSM network to support EDGE technology and tripled data services rates. Today we continue supporting and modernizing our 2G network, and we put the prime focus on the development of our 3G and LTE networks in order to provide our subscribers with high-speed broadband wireless services.

        Our 3G network, developed from 2009, has mainly reused our existing GSM infrastructure in order to minimize 3G network roll-out time and decrease capital and operating costs. Initially we deployed UMTS-2100 technology and provided data rates up to 3.6 Mbit/s. In 2010 we implemented 3G/HSDPA technology to boost download data rates up to 14.4 Mbit/s. In 2011 we began to re-allocate available GSM spectrum and launched UMTS 900 in the UMTS-2100 restricted areas: in Moscow region and Khabarovsk region. In 2012 we improved the data services rate 3G network by up to 21 Mbit/s for the downlink using 3G/HSPA+ technology. As of December 2015 we activated second and third carriers on the 91% of our 3G sites to improve capacity, and launched ultra high-speed services, based on Dual Carrier (DC-HSPA+) technology, with download rates up to 42 Mbps in 89% 3G sites in Russia.

        Since 2009, we have offered UMTS services in Armenia. We significantly improved our infrastructure, expanding 3G network coverage and capacity since then. At present HSPA+ technology with 64QAM and Dual Carrier features is available for the 98% of the Armenian population. In 2016, we are planning to further expand our 3G network coverage and capacity, implementing small cell and multi beam antenna solutions.

        In October 2015, we started providing 3G services in major Ukrainian cities. HSPA+ (64QAM and Dual Carrier) technology is available in our 3G network and provides download speed up to 42 Mbit/s.

        In Uzbekistan and in Turkmenistan we also provide UMTS services with HSPA+ technology.

        The first commercial LTE FDD 2600 network launched in Armenia was ours in 2010. In September 2012, we launched a commercial LTE TDD 2600 network in Moscow and in 2013 we started LTE FDD rollout in Russia in 2600 and 800 spectrum. In our LTE network we provide data services with a download data rate up to 150 Mbit/s, and up to 50 Mbit/s uplink. We implemented MIMO2x2, 4RxDiv and 64QAM technologies to maximize spectrum efficiency. Our LTE network meets requirements of 3GPP Rel.10 in line with available LTE customer equipment.

        In 2014, we launched several LTE FDD Small Cells' pilot zones in Moscow and St. Petersburg. In 2015, we started commercial rollout of the LTE Small Cells in other regions of Russia. We plan to use LTE Small Cells in hotspots to improve user experience and upload traffic from macro. Also, Small Cells could be used for coverage improvement both, for indoor and outdoor.

        In December 2013, we were allowed to re-allocate the existing 900 and 1800 MHz spectrum to UMTS-900 and LTE-1800 all over the Russia. Our strategy is to re-allocate available spectrum to the most efficient technology and provide competitive high-performance data services to our customers. In

2014, we started DCS 1800 spectrum refarming to LTE and roll out of LTE-1800 network, while also expanding LTE 2600/800 coverage. In 2015, we performed successful trial of three-band Carrier Aggregation with download rates up to 262 Mbit/s. As of December 2015, we implemented Carrier Aggregation on a commercial LTE FDD network on the 17% of our LTE sites.

        In 2014, we launched an LTE-2600 Active RAN Sharing program with VimpelCom (trademark "Beeline") to jointly plan, develop and use LTE networks in Russia. Under the agreement, in 2014 - 2016, we will develop shared mobile data networks in 19 regions in Russia, while VimpelCom will construct networks in 17 regions. We expect this partnership to boost 4G/LTE expansion in Russia, creating a modern telecommunications infrastructure, which will expand 4G/LTE coverage and improve the performance of our networks. Besides it will give us investment and operational savings. We are planning to launch MOCN technology (Multi-Operator Core Network) at shared LTE sites in 2016.

        In 2016, we plan to partly switch from the 1800 MHz frequency band to LTE in Armenia, and launch LTE FDD network in 800 MHz frequency band in Uzbekistan, implementing Carrier Aggregation technology where feasible.

Network Infrastructure and Frequency Allocation

        We use switching and other network equipment supplied by Nokia Solutions and Networks, Ericsson, Huawei, Alcatel-Lucent, Samsung and other major network equipment manufacturers.

        In the Moscow license area, we have been allocated frequencies spanning 2 × 11.4 MHz of spectrum in the GSM 900 frequency band and 2 × 24.6 MHz of spectrum in the GSM 1800 frequency band for operation of a dual GSM 900/1800 network and UMTS900 network. In 2011, we were allocated frequencies 2595-2620 MHz spanning 25 MHz for LTE TDD network deployment in Moscow and the Moscow region.

        In St. Petersburg and the Leningrad region, we have been allocated frequencies spanning 2 × 9.6 MHz of spectrum in the GSM 900 frequency band (including 2 × 1.6 MHz in the E-GSM band) and 2 × 18.2 MHz of spectrum in the GSM 1800 frequency band for operation of a dual GSM 900/1800 network.

        We have been allocated frequencies 1950-1965 MHz, 2010-2015 MHz and 2140-2155 MHz in the UMTS core frequency bands spanning 2×15 MHz (for FDD mode) and 5 MHz (for TDD mode) for UMTS network deployment for the entire territory of the Russian Federation.

        We have been allocated frequency bands 2540-2550 MHz and 2660-2670 MHz spanning 2 × 10 MHz and frequency bands 798. 5-806 MHz and 839.5-847 MHz spanning 2 × 7.5 MHz for LTE FDD network deployment for the entire territory of the Russian Federation.

        We have frequencies allocated to us for the operation of GSM 900 and GSM 1800 frequency bands in all regions of Ukraine. The radio frequencies allocated to MTS Ukraine for the operation of GSM 900 span from 2 × 3.6 MHz of spectrum in Crimea to 2 × 5.8 MHz in the Nikolaev, Lugansk, Chernovtsy and Kirovograd regions and in Kiev. We also have been allocated frequencies spanning from 2 × 20.0 MHz in the Kiev region to 2 × 26.6 MHz in the Dnepropetrovsk region for operation of GSM 1800 base stations. In addition, we have been allocated frequencies spanning from 453.35-457.1 MHz and 463.35-467.1 MHz in the CDMA-450 core frequency and bands spanning 3 × 1.25 MHz for CDMA-450 network deployment for the entire territory of the Ukraine. In 2015, we were allocated frequencies1950-1965 MHz and 2140-2155 MHz for UMTS network deployment for the entire territory of Ukraine.

        We believe that we have been allocated adequate spectrum in each of our license areas.

Base Station Site Procurement and Maintenance

        The process of obtaining appropriate sites requires that our personnel coordinate, among other things, site-specific requirements for engineering and design, leasing of the required space, obtaining all necessary governmental permits, construction of the facility and equipment installation. In Russia, we use special radio planning software supplied by TEOCO Corporation to assess new sites so that the network design and site development are coordinated. This software can create digital cellular coverage maps of our licensed areas, taking into account the peculiarities of the urban landscape, including the reflection of radio waves from buildings and moving automobiles and supports all necessary technologies, such as 2G, 3G, LTE and Wi-Fi. To use these tools more effectively we purchase high quality 3D digital maps for more precise planning. Used together, these software tools enable us to plan base station sites without the need for numerous field trips and on-site testing, saving us considerable time and money in our network build-out.

        Base station site contracts are essentially cooperation agreements that allow us to use space for our base stations and other network equipment. The terms of these agreements range from one to 49 years, with the term of the majority of these agreements being one to five years. Under these agreements, we have the right to use premises located in attics or on top floors of buildings for base stations and space on roofs for antennas. In areas where a suitable base station site is unavailable, we construct towers to accommodate base station antennas, mainly on leased plots of land. We anticipate that we will be able to continue to use our existing GSM 900 base station sites and to co-locate GSM 1800, UMTS 2100 and UMTS 900 base stations at some of the same sites. In 2015, we continued to rollout LTE network and started the large-scale development of LTE1800 network, the latter amounted to 57% of the newly installed LTE base stations.

Network Monitoring Equipment

        We constantly control and monitor the performance of our network, call completion rate and other major key technical performance indicators. We use monitoring systems to optimize our network and to locate and identify the cause of failures or problems, and also to analyze our network performance and obtain network statistics. We have agreements with different suppliers for technical support services that allow us to obtain their assistance in trouble shooting and correcting problems with our network within the warranty period.

        To provide high quality service to our subscribers in Russia, we have a global network operation center ("GNOC") in Krasnodar. The GNOC experts have the technical ability to monitor network problems and unusual situations online in seven macro-regions of Russia including the macro-region "Moscow" around the clock. Our maintenance department, staffed 24 hours per day, performs daily network integrity checks and responds to reported problems. Our technicians inspect base stations and carry out preventative maintenance at least once every six months.

        The GNOC in Krasnodar allows us to centralize such functions as monitoring and controlling of equipment, network planning and optimization, and also helps to solve incidents related to service interruptions. The GNOC strengthens our network's reliability and safety, as well as creates the necessary conditions to launch and implement new technologies and network standards.

        The macro-region "Moscow" is being served by the GNOC from year 2014. It had been served by the local network operation center in Moscow before.

        We also have local operation and maintenance center in Voronezh which takes the form of outsourcing partnership with Nokia Solutions and Networks and is used for network monitoring in macro-region "Center."

        In November 2015, a Global Fixed Network Operation Center (GFNOC) was launched in Nizhny Novgorod, thus completing the centralization process of the MTS mobile and fixed network

management. The GFNOC combined functions of monitoring and controlling the equipment in all 140 cities of Russia where MTS offers broadband Internet access, TV and fixed line telephony services. For the subscribers connected to these services the GFNOC acts as a single entry point for technical support. Under the GFNOC project a centralized unit was also set up which is responsible for the quality of the services provided to corporate customers with bundled packages of mobile and fixed communications.

        With the Global Fixed Network Operation Center deployed, we put together all resources for management of the quality of provided mobile and fixed line voice services, data transmission via mobile and fixed networks, leased dedicated digital circuits and VPN channels and digital TV.

        Our networks in Ukraine, Turkmenistan, Armenia, Uzbekistan and Belarus are monitored by our local operation and maintenance centers in each country. In addition to the monitoring of network performance, those centers analyze network quality parameters, provide troubleshooting, regular and extraordinary reporting to the management and our headquarters.

        The handling of any significant network problems and outages is monitored and coordinated at our headquarters in Moscow, where we also manage the cross- functional coordination of our networks in all countries of operation.

Interconnect Arrangements and Telephone Numbering Capacity

        We operate various types of communications networks, including mobile cellular, DLD/ILD and local fixed line and zonal fixed line networks.

        Cellular operators must interconnect with fixed zonal, wireless, long distance and international telephone operators to obtain access to their networks and, via these operators, to the networks of other operators around the world. Cellular and fixed line operators must also obtain telephone numbering capacity to allocate to their subscribers. There are two categories of telephone numbers: "federal" 11-digit numbers (non-geographical numbering plan for cellular operators) and "local" seven-digit numbers (geographical numbering plan for fixed-line operators which can also be used as additional numbering capacity for mobile operators). In Moscow, both "federal" and "local" numbers have been used in the 11-digit format since the beginning of 2011. We have entered into various agreements for the provision of local telephone numbering capacity with several local telecommunications operators in Moscow and in other regions of Russia and in Ukraine. We have also built our own local networks in certain cities within Russia (including Moscow) to provide local telephone numbering capacity to our subscribers. We are allocated federal telephone numbering capacity by the government and we provide interconnect services to other operators on the zonal level in all regions of Russia. Our fixed line zonal and local networks in Russia are interconnected with other operators. Zonal/local interconnect typically entails payment of a one-time connection fee per point of interconnect (E1) and a usage charge based on minutes of traffic. Operators with a substantial market position may also charge a guarantee monthly usage fee in case traffic is less than 30 kmin per E1.

        The Ministry of Communications and Mass Media has allocated special numbering codes for federal 11-digit telephone numbers on a non-geographical basis for all cellular operators. We believe that we have been allocated sufficient numbering capacity for the development of our network. However, a combination of regulatory, technological and financial factors has led to the limited availability of local 7-digit telephone numbering capacity in Moscow and the Moscow region. Moscow's "495" code and the Moscow region's "496" code have already reached numbering capacity limits. As a result, the new "499" code was introduced in order to increase the Moscow numbering capacity, the "498" code was introduced to increase Moscow region numbering capacity and since 2011 "local" numbers have been used in Moscow in 11-digit format.

Table of Contents

        To meet subscriber demand and provide for an adequate inventory of numbering capacity, we previously entered into contracts with local fixed line providers for allocation of numbering capacity to us. However, the Ministry of Communications and Mass Media subsequently took the view that numbering capacity assigned to one operator could not be rented to other operators. Accordingly, we have entered into arrangements whereby fixed line operators make their numbers available to our subscribers via agency contracts between the subscribers and us acting on behalf of such fixed line operators. Our right to use numbering capacity ranges from five years to an unlimited period of time. As a result of our merger with Comstar, we have decreased the use of local numbering capacity of other operators. As of December 31, 2015, we had numbering capacity (federal and local) for approximately 34.26 million subscribers in the Moscow license area.

        To provide our subscribers in Russia with DLD/ILD services, we have interconnect agreements with national operators Rostelecom, MTT (an affiliate of Sistema until March 18, 2009), VimpelCom and other national transit operators. We have also built and operate our own DLD/ILD network, which allows us to interconnect directly to foreign operators and thereby decrease our interconnect costs. Most interconnect fees payable for connecting users of other operators' fixed line and wireless networks to our network are based on a one-time connection fee, a monthly fee per point of interconnect and usage by minute which vary depending on the destination called.

        Russian legislation provides that fixed line operators with a substantial position in the market cannot refuse to provide interconnect or discriminate against one operator in relation to another, and the interconnect rates of operators with a substantial position are regulated by the government. See "Item 4. Information on Our Company—B. Business Overview—Regulation of Telecommunications in the Russian Federation and Ukraine—Regulation in the Russian Federation—Competition, Interconnect and Pricing" and "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Business—If we cannot interconnect cost-effectively with other telecommunications operators, we may be unable to provide services at competitive prices and therefore lose market share and revenues."

        Interconnect and traffic transit between the networks of mobile operators in Russia occurs through direct channels connecting the switches of the different mobile operators within the same city; through the network of transit long distance operators, which connect the networks of different mobile operators in different cities; or through operators' proprietary long distance networks. For domestic long distance traffic transit, we use our DLD/ILD network and networks of different national operators, including among others, MTT, Rostelecom and VimpelCom. For ILD traffic transit, we primarily use our DLD/ILD network which is interconnected with more than 47 international carriers. We also have an interconnect between the DLD/ILD MTS network and the ILD networks of our subsidiaries, MTS Ukraine and K-Telecom, in order to provide transit for international traffic.

        In Ukraine, mobile operators are allocated numbering capacity by the NCCIR (National Commission for the State Regulation of Communications and Informatization). We believe that we have been allocated sufficient numbering capacity in Ukraine for the development of our mobile network. We also believe that we have been allocated sufficient fixed line numbering capacity with respect to the cities in which we are developing our fixed line network.

Handsets

        Nearly all of our handset sales consist of tri-band GSM 900/1800/1900 and dual-band UMTS 900/2100 handsets, except for certain models in the low cost segment and touch-phones. These handsets, which function in the GSM 900, GSM 1800 and PCS-1900 standards, provide users with greater automatic roaming possibilities in Russia, Europe, the United States and Canada. In 2013, we launched LTE 800 and LTE 2600. In 2014, we launched LTE 1800 and activated current functionality in LTE devices. After network upgrade to DC-HSPA (43,2 Mb/s) all HSPA+ & DC- HSPA devices in the network increase their working speeds.

        From 2009, RTC, our wholly-owned subsidiary, started handling all functions relating to our retail operations, including the purchase and sale of handsets and accessories and subscriber enrollment at our retail outlets. RTC has entered into arrangements with Sony, Microsoft, Samsung, HTC, Alcatel, Fly, Philips, Huawei, ZTE and others to purchase handsets. In 2015, we continued our cooperation with A-brand smartphone vendors and extended our partnership with Google. We also offer an array of mobile telephone accessories. Since 2009 we have been successfully selling MTS branded phones and since 2013 our main focus of MTS branded devices are smartphones. Currently, most of MTS branded smartphones support LTE.

Fixed Line Services

        We offer fixed line communications services in over 185 cities across Russia, covering a population of over 53 million people.

        Our Moscow fixed line operations incompass communications services provided through incumbent operator MGTS. Through MGTS, we own "last mile" access to approximately 3.9 million households in Moscow, excluding territory of New Moscow, representing approximately 95% of the overall number of households. MGTS provides regulated and unregulated services, including:

•

local and zonal telephony services at tariffs regulated by the Russian government;



•

DLD/ILD voice telephony through licensed operators;



•

Internet services;



•

pay-TV services;



•

interconnect and rent data channels to other operators;



•

rent of fixed line infrastructure; and



•

internet and data transmission services and numbering capacity to subscribers of other communications operators through agency agreements concluded with such operators.

        Our other fixed line operations include the following communications services: voice, data and Internet and pay-TV services for corporate and residential subscribers, as well as the provision of interconnect services to other communications operators and numbering capacity to their subscribers. Based on TMT Consulting data, as of December 31, 2015, we are the largest operator in the Moscow residential broadband market in terms of subscribers, with a 30% market share. We also operate in Ukraine and Armenia, where we provide digital telephony communications services, data transmission, Internet access and the renting of channels. For a list of the telecommunications licenses held by us, see "Item 4. Information on Our Company—B. Business Overview—Regulation of Telecommunications in the Russian Federation and Ukraine—Licenses."

Customers and Services Offered—Moscow Fixed Line Operations

        We provide fixed line communications services through our subsidiary, MGTS, which is the incumbent fixed line PSTN operator in Moscow. MGTS owns Moscow's PSTN infrastructure, including switches, a transmission network, underground ducts, and owns or holds leases to properties housing its offices and equipment.

        As of December 31, 2015, MGTS had approximately 4 million active lines in service, a cable network of over 90,293 km, a fiber optic network of over 40,340 km and 2,889 payphones. Currently, MGTS has focused its efforts on the deployment of GPON, IP/MPLS technologies and an IMS core. The old SDH equipment is being removed which results in the decreased number of E1 streams, a reduction in the copper network and the respective extension of the fiber- optic network. MGTS also develops new services for IP TV, and MVNO as the convergent service for mobile and fixed telephony.

Table of Contents

        The total installed capacity of the telephone network reached 4.3 million numbers on the TDM area (Time Division Multiplexing) and 5.18 million numbers on the IMS area (IP Multimedia Subsystem) as of December 31, 2015.

        Residential subscribers accounted for approximately 82% of MGTS' total lines, corporates for 10% and public sector subscribers for 8%, as of December 31, 2015.

        MGTS holds licenses and regulatory approvals to provide, among others, the following services:

•

local telephony;



•

DLD/ILD voice telephony through licensed DLD/ILD operators, including us;



•

interconnect to other operators;



•

Internet and data transmission, including leased DLD/ILD services;



•

IP TV for B2C and B2B subscribers;



•

MVNO mobile telephony and Internet;



•

inquiry and information, including telephone directories;



•

local telephony with use of payphones;



•

telematic communications services;



•

telecommunications services associated with providing of communication channel;



•

telecommunications services associated with voice data transmission;



•

telecommunications services associated with cablecasting;



•

movable radiotelephony services; and



•

measures and (or) services for the protection of State secrets.

        As the only licensed PSTN operator in Moscow, MGTS is considered a natural monopoly under Russian antimonopoly regulations. Consequently, substantial part of services provided by MGTS are subject to governmental regulation. The Federal Tariff Service regulates MGTS' tariffs for voice telephony services provided to its PSTN subscribers, including monthly subscription fees, installation fees and local call charges. Operating revenues from regulated services are accounted for approximately 51% of service operating revenues of our Moscow fixed line operations in 2015, 54% in 2014 and 57% in 2013. The percentage decline is connected with gradual growth of operating revenues from non-regulated services as a proportion of the overall operating revenues in 2015 and 2014. The Federal Tariff Service sets the tariffs MGTS can charge taking into account cost of services, network investment and a certain profit margin, and the current tariffs fully compensate MGTS for the cost of services provided to residential and government subscribers. According to Russian legislation, MGTS is allowed to petition the Federal Tariff Service for tariff increases upon certain conditions, such as inflation or increases in the cost of services. Historically, MGTS has petitioned the relevant Russian government agency for tariff increases once or twice per year. The Federal Tariff Service has permitted MGTS to increase its tariffs several times.

        MGTS also provides a number of unregulated services. According to Russian legislation, DLD/ILD services provided by licensed non-monopoly operators, public payphones, data transmission services, value-added services and a number of other services are not subject to tariff regulation. Among others, MGTS provides the following unregulated services:

•

various value-added services, including call forwarding, call waiting, call holding, caller ID, provision of second direct inward dialing (DID) number;

•

Internet access for residential subscribers and corporates;



•

IP TV for B2C and B2B subscribers;



•

MVNO mobile telephony and Internet; and



•

rent of space for telecommunications equipment of other operators connected to MGTS' network.

        MGTS does not have license to provide DLD/ILD communications services directly to its subscribers but must route such traffic through a licensed DLD/ILD operator. As a result, DLD/ILD traffic originated by MGTS subscribers is carried either by us, with these services included in MGTS' monthly bill, or by other providers of DLD/ILD services, who bill MGTS subscribers directly or pay MGTS an agency fee for processing their bills.

        The following table presents certain operating data for our Moscow fixed line operations as of and for the years ended December 31, 2014 and 2015.

        MGTS' subscriber segments and the services provided to each subscriber segment are further described below.

Residential and corporate subscribers

        MGTS provides basic regulated voice services to residential and corporate subscribers using its PSTN facilities and copper or optical "last mile" access. Tariffs for these services are established by the Federal Tariff Service.

        In addition to basic voice services, MGTS provides its residential and corporate subscribers with digital telecommunications services, Internet, IP TV, MVNO mobile telephony and Internet and VPN deployment services, rental of high-speed communication channels, intelligent voice and various other services.

Interconnect is carried out on the local and zonal levels in accordance with terms and conditions that are publicly disclosed. MGTS also provides additional services to operators interconnecting to MGTS' network, including access to emergency service, information and customer care numbers.

        MGTS has also established an active presence in the data transmission market. Through its PDTN, MGTS can establish VPNs for other operators as well as provide other data network services. Operators can also rent space and utility systems from MGTS to house their network equipment.

Customers and Services Offered—Other Fixed Line Operations

        We provide fixed line communications services to corporate, operator and residential subscribers in over 185 cities throughout Russia. Specifically, we offer local voice, DLD/ILD voice, data and Internet and pay-TV services to our subscribers. Some of the interconnect tariffs we charge other telecommunications operators for in Moscow and certain other cities are regulated by the Russian government. We believe our fixed line subscribers typically evaluate our service and product offerings based on such factors as price, technology, security, reliability and customer service.

        The following table presents certain operating data for our other fixed line operations in Russia as of and for the years ended December 31, 2014 and 2015.

Corporate subscribers

        We target corporate subscribers covering a range of industries, such as business centers, hotels, financial institutions, professional services firms, consumer goods companies, manufacturers and companies involved in extractive industries, among others. These subscribers vary in size, ranging from large multinational and Russian corporations with thousands of employees to small-and medium-sized enterprises with up to several hundred employees. As of December 31, 2015, we had approximately 47,000 voice and 70,000 Internet corporate subscribers.

        As further described below, we offer voice, data transmission and Internet and various value-added services to our corporate subscribers.

        Voice Services.    We provide a full range of other fixed line voice services to corporates in Moscow, the Moscow region and other selected regions of Russia, which include local, zonal, and DLD/ILD services using our transmission network and leased capacity between major Russian cities. We also

provide integrated voice and data services, voice over frame relay and certain integrated services digital network ("ISDN") services.

        Data Transmission and Internet Services.    We offer high quality data transmission services to corporates, which allow for data exchange between their various branches or offices located within Russia and internationally. For data transmission services, our network is capable of transferring data at speeds of up to 10 Gbps and utilizes various technologies, such as 10 GE, GE, ATM, TDM, VPN-MPLS/VPLS, GPON, Microwave radio relay (MRR), xDSL, LTE and Wi-Fi to provide high quality solutions at a relatively low cost. We endeavor to ensure the reliability of network connections by utilizing a full reservation approach to back up all elements of the network.

        In addition, we offer a wide range of Internet services to corporates, including broadband Internet access, VoIP, VPNs and data center services using the following technologies: (1) NGN (up to 10 Gbps), (2) GPON (up to 1 Gbps), (3) xDSL (up to 60 Mbps), (4) radio Ethernet (up to 300 Mbps), (5) MRR (up to 1 Gbps), (6) Wi-Fi (up to 54 Mbps), and (7) LTE (up to 100 Mbps). We also provide continuous flexibility to upgrade their network capacity to handle additional Internet services. For example, we often integrate data transmission and Internet services for our clients as they expand their operations and need to interconnect and exchange data with newly opened offices and/or branches.

        We offer a broad range of Internet packages that vary in terms of data transfer speeds and pricing, with higher tariffs for faster uploading and downloading capabilities. Corporates with GPON broadband Internet packages generally experience data transfer speeds between 1 Mbps and 1 Gbps. In addition, we offer a premium broadband Internet service over our NGN in which subscribers enjoy data transfer speeds between 61 Mbps and 10 Gbps. The NGN provides subscribers with the benefit of the same uploading and downloading data transfer speeds, whereas Internet subscribers using an xDSL/GPON connection upload at speeds that are much slower than the one at which they can download.

        We also utilize MGTS' PDTN to provide high-speed reliable Internet services and create VPNs for our corporates.

        Leased Channels.    We provide corporate clients with the ability to rent high speed data channels. These "leased channels" are dedicated lines of data transmission.

        Value-Added Services.    We provide corporates with several value-added services, including Autosekretar and integrated solutions. The Autosekretar service is based on our proprietary IN and is designed to help our corporates manage the reception and servicing of a large volume of incoming calls. The unique multi- channel telephone number assigned to customers will not change even if the customer moves to a different location in Moscow, and does not require the customer to install any equipment. In addition, this service allows all incoming calls to be transferred to other fixed or mobile telephone numbers in Russia or in other countries. The IN identifies a subscriber by phone number, phone card or password, which allows our customers to bill their subscribers for services and, if necessary, block access for subscribers who have a negative balance on their account.

        In addition, we serve as general contractor for the provision of a full range of integrated solutions to subscribers wishing to establish a modern integrated communications infrastructure. Each solution is customized for subscriber- specific needs. In developing these customized networks, we are able to offer the following range of services: site survey, cost analysis and optimum project planning, assistance with government-related documentation, supply of equipment and operational, technical and maintenance support on an ongoing basis. Once the infrastructure is established or renovated, as the case may be, we typically provide digital voice communications, voice intelligent services, high-speed Internet services, videoconferencing and other data transmission services. We intend to expand our service offerings to include customer premises management and network-centric IT solutions.

        Fixed mobile convergence.    Based on our fixed and mobile networks, we offer fixed-to-mobile convergence services to corporate clients providing use of their mobile phone as an extension of their private branch exchange ("PBX"). We also provide access to corporate IP-networks from a mobile phone via GPRS/EDGE/3G/4G.

        Equipment Sales.    We offer and sell equipment manufactured by different manufacturers.

Operators

        We are the largest mobile operator in Russia in terms of subscribers, according to AC&M-Consulting. We also operate fixed-line local and zonal networks in Moscow and other cities for provision of telephony services to fixed-line subscribers and additional local numbers to mobile subscribers. In order to lower the costs of intercity and international traffic transition, we put into operation an intercity international network in December 2008.

        According to TMT Consulting, together with MGTS, we had approximately 77% of the total active numbering capacity in Moscow as of December 31, 2015. We now have approximately 234 local fixed networks in 62 regions of Russia, including Moscow, and 41 zonal fixed networks to provide telephony services to subscribers. Our integrated intercity/international network is interconnected to more than 50 international operators. As of December 31, 2015, we had total more than 1500 interconnect agreements with national and international operators for interconnection of our networks, including fixed, mobile and Intercity/International networks.

Residential subscribers

        We offer voice, Internet and pay-TV services to residential subscribers.

        Voice Services.    We provide voice services to residential and corporate subscribers. Like corporate subscribers, residential subscribers in each of the regions that we are present in seek a full range of high quality voice services equivalent to those provided in Western Europe. In addition to "basic" voice telephony services, we provide a number of additional services, such as call forwarding, call transferring, call waiting, conference, voicemail and Caller ID, among others.

        Internet Services. We offer broadband Internet services to residential subscribers throughout Russia. As of December 31, 2015, we had 9% market share in the Russian Federation together with Moscow where we had a 30% share, based on TMT Consulting data. Depending on the Internet connection speed, we charge residential subscribers a subscription fee of RUB 300-RUB 2,500 per month in Moscow and a subscription fee of RUB 350-RUB 1,900 in other regions of Russia. We do not charge a connection fee in Moscow and in most of the Russian regions.

        Pay-TV.    We operate a TV service based on IPTV service over ADSL and GPON technologies in Moscow. In addition, we offer pay-TV services based on DVB-C (digital television via cable connection), analog cable transmission and MMDS (wireless cable) technologies in most of the regions in which we are present. Since November 2013, we connect our subscribers only to the TV with digital quality. Special auxiliary equipment (set-top box) allows pay-TV subscribers to access more than 150 channels of digital quality, including 36 channels of HD quality from a home television. International and Russian channels are included as part of the base services package.

        Our pricing structure is designed to appeal to large numbers of consumers with various interests and purchasing power, and varies significantly between regions. We charge a subscription fee of RUB 129-RUB 1,341 per month in Moscow and a subscription fee of up to RUB 100-RUB 400 in other regions of Russia, depending on the number of channels included in the package. We also offer bundled Internet and pay-TV services for RUB 600-RUB 2,500 per month in Moscow and RUB 450- RUB 3,550 in certain other regions of Russia, depending on the speed of the Internet

Sales and Marketing

Moscow fixed line operations

        As the incumbent PSTN, MGTS has not invested significantly in sales and marketing. During 2015 MGTS continued realization of its long-term modernization program on GPON and sale of its services and packages, therefore, the biggest part of advertising budget was spent on convergent products promotion like Double and Triple Play (an offer bundling two and three services) with the use of GPON technology. GPON allows us to provide higher quality services than our competitors and to increase the number of our subscribers and revenue from Internet and pay-TV services in Moscow. MGTS was the first to bring an Internet-tariff to the market with the revolutionary speed up to 500 Megabit per second, which is accessible publicly to all private subscribers of optic GPON network in any point of Moscow.

        By the end of 2015, 1.52 million subscribers were transferred to GPON. In 2016, MGTS will continue realization of its modernization program of GPON and products promotion.

Other fixed line operations

        Our target customers include corporate, operator and residential subscribers.

        To promote our product and service offerings, we use various communication channels for advertising and marketing, including direct marketing, printed mass media, television, Internet, radio, directories, outdoor advertising, advertising in the subway, special promotions and cross promotions. Through these various advertising and marketing channels, we intend to further develop our brand recognition. Our marketing strategy is designed to create a unified brand for each of our various product and service offerings with the aim of becoming a single source for all of our subscribers' communications needs.

        We also actively promote our services to existing subscribers with special bundled product offerings aimed at servicing their communication requirements and enhancing subscriber loyalty. Our advertising and marketing materials are aimed primarily at the promotion of MTS brand. All fixed-line products are offered and marketed under this brand. However, when we enter new markets and acquire existing companies, we have to use both brands in advertising—MTS brand and the acquired brand. This is done to decrease churn as customers tend to express strong loyalty towards local brands. We then gradually decrease presence of the acquired brand and this allows us to make MTS a market leader in a given region in future. Our advertising and marketing efforts are designed to convey a positive image of us to the market as a leading communications operator focused on customer satisfaction.

Competition

        We compete with a number of fixed line telecommunications operators servicing Moscow, St. Petersburg and other major Russian cities. Moscow is the largest and most competitive of these markets. Our primary competitors include:

        In the TV market, we generally compete on the basis of pricing, channel selection and content, individual and bundled service offerings, customer service and installation time.

Tariffs

        We establish prices for our unregulated services and different subscriber segments based on certain common considerations, policies and goals. For example, we generally seek to establish competitive prices based on market rates for the services we offer and below market prices when our lower-than-average costs or economies of scale allow us to do so. We also offer subscribers bundled service packages with several services offered together at a discount to the cost of ordering each individual service separately and to promote additional services to our existing subscribers. In addition, we often offer promotions to our various subscriber segments waiving or discounting installation fees in order to attract new subscribers or promote new services.

Table of Contents

        With regard to corporates, we generally aim to derive the bulk of our operating revenues from monthly payments. Thus, depending on the scale and type of services ordered, we will often discount or waive installation fees.

        For services offered to other communications service providers, we aim to generate most of our operating revenues from monthly payments and by offering an array of value-added services.

        We develop tariffs for service offerings to residential subscribers with the aim of attracting new subscribers, as well as expanding the services used by existing subscribers in order to generate higher ARPU.

Network Infrastructure

The transport network

        As a result of our acquisitions of Comstar and Evrotel, we became one of the largest operators of the Internet long-haul backbone networks in Russia. We continue to develop our long-haul backbone network through the build-out of a fiber optic infrastructure, based on 100G technology, and acquisitions of other Internet backbone service providers. We currently have a fiber optic network of approximately 170,000 km, which also allows us to operate an optical transport network using dense wavelength division multiplexing technology. Our network crosses the Russian Federation state border 4 times (Finland, Ukraine, Belarus, China).

        In addition, we have our own IP MPLS network, which is capable of providing Internet and L2/L3 VPN services, as well as deliver other media products, such as digital television and internet protocol television, to regional networks for the use in our fixed line and mobile operations, as well as for our wholesale customers. Our IP MPLS backbone network covers most of Russia and Ukraine and is present in most of the European and U.S. Internet exchange points, such as DE-CIX in Frankfurt, NETNOD in Stockholm, AMS-IX in Amsterdam, PARIX in Paris, LINX in London, Equinix in Ashburn and New York, NIIX in New York, Any2 in Los-Angeles and FICIX in Helsinki. More than 75% of our international Internet traffic is delivered through settlement-free peerings with other large networks. The remaining international Internet traffic is delivered through direct connections with certain of the largest networks. All internet traffic in Russia is delivered through settlement-free peering with the largest ISPs in Russia.

Other fixed line operations

        The network infrastructure we maintain in Moscow is substantially different to the infrastructures we use in the regions. In Moscow, we have primarily grown organically, while our regional development has largely been through the acquisition of companies with different business models and a focus on different services. As a result, the network infrastructures in the regions outside Moscow and the technologies used to support such infrastructures are different from the network infrastructure established in Moscow and which we currently own.

        The Moscow telephone network consists of 490 switching nodes (440 TDM switches and 50 soft switches) with total capacity of over 1,000,000 subscribers.

        All of our TDM PSTN switching centers are connected to a digital transport network, which uses SDH technology and covers the entire territory of the Russian Federation. The network ensures the functioning of our digital ATSs and their connectivity with analog and digital (TDM and VoIP) equipment of PSTNs of other operators. Due to the reducing amount of traffic and moving traffic and clients from SDH network to IP/MPLS network we plan to cease further investment. The SDH network

will be supported and operated as it is to support existing clients. The management of the transport network and digital ATSs is carried out remotely from network operation centers.

        For the provision of Internet access, IP-telephony and other services, we have our own IP MPLS network, the core of which is constructed as IP MPLS rings with routers connected to each other by means of 10 GE channels. In addition, separate routers are used for inter-carrier connections and are connected to the core routers by means of 10 GE interfaces.

        As of December 31, 2015, our wireless broadband network in Moscow and the Moscow region included 474 base stations in the 5-6 GHz frequency band.

Russian regions

        As of December 31, 2015, outside of Moscow and the Moscow region, we provide cable Internet access to 8.9 million households and cable TV access to 9.4 million households. Among the access equipment used are Ethernet switches, IP DSLAM and Optical Receivers. We mainly use FTTB technology for internet and CATV access, which can provide speeds up to 1 Gb/s per building and about 250 channel CATV (analog and digital). In 2011, we started to roll-out DVB-C technology for cable TV service. Currently, we have digital TV service (DVB-C&DVB-S2) in more than 100 cities with more than 1.8 million of subscribers. In 2014, we started to roll-out an advanced hybrid TV service (DVBC/DVB-S2/IPTV+IP/VOD, CatchUp). By December 2015, we launched Hybrid TV platform with IPTV commercial service in Moscow and Moscow Region (MGTS), DVB-C/IP Hybrid commercial service in 3 regional cities and DVB-S2/IP Hybrid commercial service all over Russia. Total number of connected hybrid TV users is abount 0.1 million. In 2015, we also completed "TV Everywhere" project which provided integration between platforms of mobile and fixed cable TV in regions in terms of cross-functional tariff proposal. In 2016, we plan to continue roll-out of DVB-C/IP Hybrid solution with target up to 60 more regional cities connected to the service and to launch fully integrated OTT solution for STB, connected TV, browsers and mobile devices merging current services of mobile and fixed digital TV in terms of services and user profile.

        In Moscow and regions as an Internet traffic supplier, we mainly use MTS own IP Backbone network described in the "transport network" section.

        The acquisition of Comstar provided us with an opportunity to use MTS fiber optic lines for fixed network development. Optical network construction in cities is carried out on the basis of fixed and mobile business needs. When we modernize and construct new networks, we deploy fixed and mobile equipment on the basis of "collocation" method.

Principal suppliers

        Our principal suppliers are Ericsson, NVision Group, our related party, Cisco Systems, Huawei, Nokia Solutions and Networks for switching equipment; ECI Telecom, Tellabs and Alcatel Lucent for transport network equipment; Cisco Systems, Huawei and Alcatel Lucent for Internet and data network equipment; Secure Media for crypto-protection conditional access software; and Tandberg TV (Ericsson), Irdeto for broadcasting equipment. All of our equipment is supplied directly through authorized dealers.

Seasonality

        Our results of operations are impacted by certain seasonal trends. Generally, revenue is higher during the second and third quarter due to increased mobile phone use by subscribers who travel in the summer from urban areas to more rural areas where fixed line penetration is relatively low, as well as an increase in roaming revenues and guest roaming revenues during these quarters. Quarterly trends can also be influenced by a number of factors, including new marketing campaigns and promotions, and may not be consistent from year to year.

Regulation of Telecommunications in the Russian Federation and Ukraine

Regulation in the Russian Federation

        In the Russian Federation, the federal government regulates telecommunications services. The principal law regulating telecommunications in the Russian Federation is the Federal Law on Communications, which provides, among other elements, for the following:

•

licensing of telecommunications services;



•

requirements for obtaining a radio frequency allocation;



•

equipment certification;



•

equal rights for individuals and legal entities, including foreign individuals and legal entities, to offer telecommunications services;



•

fair competition;



•

freedom of pricing other than pricing by companies with a substantial position in public telecommunication networks; and



•

liability for violations of Russian legislation on telecommunications.

        The Federal Law on Communications came into force on January 1, 2004, and replaced the law of 1995 regulating the same subject matter. The Federal Law on Communications creates a framework in which government authorities may enact specific regulations. Regulations enacted under the legislative framework in place prior to the enactment of the Federal Law on Communications continue to be applied to the extent they do not conflict with the Federal Law on Communications. The lack of interpretive guidance from the regulatory authorities regarding the new regulations and the uncertainty surrounding their compatibility with the regulations still in effect impedes our ability to assess effectively the full impact of the new regulations under the Federal Law on Communications on our business.

        The Federal Law on Communications, which confers broad powers to the state to regulate the communications industry, including the allocation of frequencies, the establishment of fees for frequency use and the allocation and revocation of numbering capacity, significantly modifies the system of government regulation of the provision of communications services in Russia. In particular, licenses to provide communications services in territories where frequency and numbering capacity are limited may be issued only on the basis of a tender, whereas according to the Government Decree No. 480 dated May 24, 2014, licenses to provide communication services with frequency spectrum—only on auction basis. In addition, the Federal Law on Communications provides for the establishment of a "universal services reserve fund" which is funded by a levy imposed on all operators of public networks, including us.

Regulatory Authorities

        The Russian telecommunications industry is regulated by several governmental agencies. These agencies form a complex, multi-tier system of regulation that resulted, in part, from the implementation of the Federal Law on Communications, as well as from the large-scale restructuring of the Russian government in March 2004 and subsequent restructuring in May 2008. The system of regulation is still evolving and further changes are expected. See also "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Countries of Operation—Political and Social Risks—Political and governmental instability in Russia and other countries of our operations could materially adversely affect our business, financial condition, results of operations and prospects and the value of our shares and ADSs."

regulations relating to the protection of consumer rights. The Federal Service for State Registration, Cadastre and Cartography is responsible for registering certain telecommunications infrastructure that is considered real property in accordance with Government Decree No. 68 dated February 11, 2005. The Federal Service for Financial Monitoring (Rosfinmonitoring) is a federal executive body responsible for countering money laundering and terrorism financing. Mobile operators are to comply with Federal Law No. 115-FZ dated August 7, 2001 "On combating money laundering and terrorist financing."

Licensing of Telecommunications Services and Radio Frequency Allocation

        Telecommunications licenses are issued based on the Federal Law on Communications and Government Decree No. 480 dated May 24, 2014 on Bidding Process (Auctions, Tenders) for Receipt of Telecommunications License. Under these regulations, licenses may be issued and renewed for periods ranging from three to twenty-five years. Several different licenses to conduct different communication services may be issued to one entity. Provided the licensee has conducted its activities in accordance with the applicable law and terms of the license, renewals may be obtained upon application to the Federal Service for Supervision of Communications, Information Technologies and Mass Media. Officials of the Federal Service for Supervision of Communications, Information Technologies and Mass Media have broad discretion with respect to both issuance and renewal procedures.

        A company must complete a multi-stage process before the commercial launch of its communications network. A company must:

•

receive a license from the Federal Service for Supervision of Communications, Information Technologies and Mass Media to provide communications services;



•

obtain approval to use specific frequencies within the specified band from the State Radio Frequencies Commission if providing wireless telecommunications services; and



•

obtain permission from the Federal Service for Supervision of Communications, Information Technologies and Mass Media for network operations. To receive this permission, a wireless telecommunications services provider must develop a frequency assignment and site plan, which is then reviewed and certified by the Federal Service for Supervision of Communications, Information Technologies and Mass Media for electromagnetic compatibility of the proposed cellular network with other radio equipment operating in the license area. The Federal Service for Supervision of Communications, Information Technologies and Mass Media has discretion to modify this plan, if necessary, to ensure such compatibility. Effective January 1, 2004, licenses may be transferred in case of mergers or other reorganizations of the licensee upon application by a transferee as a new license holder. Additionally, the Ministry of Communications and Mass Media has declared that agreements on the provision of telecommunications services must be concluded and performed by the license holder.

        If the terms of a license are not fulfilled or the service provider violates applicable legislation, the license may be suspended or terminated. Licenses may be suspended for various reasons, including:

•

detection of violations which may cause damage to rights, interests, life or health of individuals or to interests of government administration including, but not limited to, presidential and government telecommunication networks, defense, security and protection of legal order in the Russian Federation;



•

annulment of a frequency allocation if it results in the inability to render communications services;

121

---

Table of Contents

•

failure in a timely requirements of the licensing authority, which commits to eliminate detected violations, including provisions that had been granted under reprimand to suspend the license.

        In addition, licenses may be terminated for various reasons by a court, including:

•

failure to remedy in a timely manner a violation that led to the suspension of the license;



•

provision of inaccurate information in documents on the basis of which a license was issued; and



•

failure to fulfill obligations undertaken in the process of a tender or auction.

        The license may also be terminated by the Federal Service for Supervision of Communications, Information Technologies and Mass Media in a number of cases, including liquidation of a license holder. A suspension or termination of a license may be appealed in court.

        Frequencies are allocated for a maximum term of ten years, which may be extended upon the application of a frequency user. Under the Federal Law on Communications, frequency allocations may be changed for purposes of state management, defense, security and protection of legal order in the Russian Federation with the license holder to be compensated for related losses. Further, frequency allocations may be suspended or terminated for a number of reasons, including failure to comply with the conditions on which the frequency was allocated.

        The following one-time license fee is payable irrespective of the number of regions covered by the license: RUB 7,500 for services involving, among other things, the use of a frequency spectrum and the lease of communication channels. The license fee for a license received through a tender or auction is determined by the terms of such tender or auction.

        In addition to licensing fees, a Government Decree enacted on June 2, 1998, required payment of fees for the use of radio frequencies for cellular telephone services. The payment procedure was established by a Government Decree enacted on August 6, 1998, which required that all wireless telecommunications services operators pay an annual fee set by the State Radio Frequencies Commission and approved by FAS for the use of their frequency spectrums. On January 1, 2012, a new Government Decree No. 171 dated March 16, 2011 came into force which provides that fees for the use of radio frequency spectrums consist of a one-time fee and an annual fee. The fees are determined according to the methodology approved by the Ministry of Communications and Mass Media.

        Furthermore, the Federal Law on Communications provides for the establishment of a "universal services reserve fund" for the purpose of supporting communications companies operating in less developed regions of Russia through the financing, construction and maintenance of telecommunications networks in low-profit and unprofitable sectors. This reserve fund is aimed at eliminating the practice of cross-subsidies by compensating operators for certain mandatory, loss-making local services in rural and sparsely populated areas. It is funded by a levy imposed on all operators of public networks, including us, in the amount of 1.2% of revenues from telecommunications services less the amount of taxes paid by subscribers. The universal service fund concept has been used in some developed countries and in Eastern Europe.

        The Federal Law on Communications empowers the Russian government to determine and annually review the list of licensing requirements applicable to various communication services being licensed. The list of licensing requirements was enacted by Government Decree No. 87 dated February 18, 2005, as amended. Licenses also generally contain a number of other detailed conditions, including a date by which service must begin, technical standards and certain other terms and conditions. We have either commenced service by the applicable deadline or received an extension of the applicable deadline for all of our licenses.

Equipment Certification

        Government Decree No. 532 adopted on June 25, 2009, sets forth the types of communications equipment that is subject to mandatory certification. Communications equipment must be certified, or its compliance with the established requirements must be declared and proven in the interconnected communications network of the Russian Federation, which includes all fixed line and wireless networks open to the public. All our networks must be certified. The Federal Communications Agency issues certificates of compliance with technical requirements to equipment suppliers based on the Agency's internal review. In addition, a Presidential decree requires that licenses and equipment certifications should be obtained from the Federal Security Service to design, produce, sell, use or import encryption devices. Some commonly used digital cellular telephones are designed with encryption capabilities and must be certified by the Federal Security Service.

        Further, certain high-frequency equipment, a list of which was approved by Government Decree No. 539 dated October 12, 2004 (as amended), manufactured or used in the Russian Federation, requires special permission from the Federal Service for Supervision of Communications, Information Technologies and Mass Media . Failure to receive such certification could result in the mandatory cessation of the use of such equipment. In accordance to Government Decree No. 1252 dated November 27, 2014, the equipment can be shared by operators according to their agreement and certificate of the Federal Service for Supervision of Communications, Information Technologies and Mass Media.

Competition, Interconnect and Pricing

        The Federal Law on Communications requires federal regulatory agencies to encourage competition in the provision of communication services and prohibits the abuse of a dominant position to limit competition. The Federal Law on Communications provides that telecommunications tariffs may be regulated in cases provided for by legislation. The Federal Law on Communications and Presidential Decree No. 221, enacted on February 28, 1995, as amended, on Measures for Streamlining State Regulation of Prices (Tariffs) allow for regulation of tariffs and other commercial activities of telecommunications companies that are "natural monopolies." Government Decree No. 637, dated October 24, 2005 (as amended by the Government Decree No. 941, dated September 4, 2015) authorized FAS to set the following tariffs for the natural monopolies in the communications market, including:

•

provision of access to a local telephone network;



•

permanent use of a subscriber's line; and



•

local, intra-zone and DLD calls.

        In addition, the Federal Law on Natural Monopolies No. 147 dated August 17, 1995 establishes the legal basis for federal regulation of natural monopolies, including those in the communications market, and provides for governmental control over tariffs and certain activities of the natural monopolies. The Federal Law on Natural Monopolies outlines the types of transactions for which a regulated entity must obtain prior FAS approval and establishes the general principle that regulated entities may not refuse to provide regulated services to certain types of consumers. Regulated entities are also subject to continuous reporting requirements, including submitting plans for capital investments.

        FAS maintains a Register of Natural Monopolies whose tariffs are controlled and regulated by the state. A telecommunications operator may be included in this register upon a decision by FAS based on analysis of the operator's activities and the market conditions.

123

Table of Contents

        Our subsidiary, MGTS, was added to the Register of Natural Monopolies in 2000 and, therefore, is subject to the requirements of the Federal Law on Natural Monopolies including, inter alia, the following:

•

FAS regulates and controls tariffs for services provided by MGTS, including installation fees, monthly subscription fees (for subscribers to the unlimited tariff plan) and local call charges (for subscribers who do not use the unlimited tariff plan);



•

MGTS must obtain prior FAS approval for any transaction involving the acquisition, disposal or lease of assets not related to the regulated activity, if the value of such assets exceeds 10% of MGTS' share capital, additional capital, retained profits and reserves;



•

MGTS is required to maintain separate accounting records for each type of activity;



•

MGTS is required to publicly disclose information on tariffs, products, material conditions of contracts with customers, capital expenditure programs and certain other information; and



•

MGTS is required to comply with Federal law No. 223-FZ dated July 18, 2011 "On Procurement of Goods, Works, Services by Certain Types of Legal Entities" while procurement of goods and services.

        It should also be noted that our subsidiary Comstar-Regions was added to the Register of Natural Monopolies in 2009, but on November 24, 2015 it was excluded therefrom and on December 5, 2015, it merged into MTS.

        In addition, FAS was authorized by law to maintain a register of companies holding a market share in excess of 35%. Companies included in this register could become subject to certain restrictions in conducting their business, including in relation to pricing, acquisitions, geographical expansion, and associations and agreements with competitors. We were categorized by FAS as a company with a market share exceeding 35% in Ivanovo region, Magadan region, Kurgan region, Sakhalin region, Udmurt Republic and Nenets Autonomous region. On January 5, 2016, the new version of Federal law No. 135-FZ "On protection of the competition" came into force and the regulations in relation to the abovementioned register were repealed. See also "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Business—If we are found to have a dominant position in the markets where we operate, the government may influence our subscriber tariffs and restrict our operations."

        The Federal Law on Communications also provides for the special regulation of telecommunications operators occupying a "substantial position," i.e., operators which together with their affiliates have, in the Russian Federation generally or in a geographically defined specific numerical zone, 25% or more of installed capacity or capacity to carry out transmission of not less than 25% of traffic. MGTS was added to the register of telecommunications operators occupying a substantial position and, therefore, is subject to the requirements of the Federal Law on Communications relating to operators occupying a substantial position in the public switched telephone networks including, inter alia, the following:

•

MGTS must develop interconnect rules and procedures in accordance with the requirements set forth by the federal government;



•

MGTS must ensure that interconnect agreements with operators who intend to interconnect to our networks are entered on the same terms and conditions as the agreements between MGTS, us and our affiliates; MGTS also cannot refuse to provide interconnect or discriminate against one operator over another;



•

MGTS must comply with the mandatory orders of the Federal Service for Supervision of Communications, Information Technologies and Mass Media issued if non-compliance with law was identified as a result of monitoring of MGTS' interconnect terms; and

124

---

Table of Contents

•

MGTS must comply with the tariffs for interconnect and traffic transit where determined by the Federal Communications Agency.

        The Federal Law on Communications and implementation rules adopted by Government Decrees No. 161 dated March 28, 2005, and No. 627 dated October 19, 2005, also provides for government regulation of interconnect tariffs established by operators occupying a substantial position. In addition, such operators, including MGTS, are required to develop standard interconnect contracts and publish them as a public offer for all operators who intend to use such interconnect services.

        Notwithstanding the above, fixed line operators not considered to occupy a substantial position and not included in the Register of Natural Monopolies, as well as mobile operators, are free to set their own tariffs. Also see "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Business—If we or any of our mobile operator subsidiaries operating in Russia are identified as an operator occupying a "substantial position," the regulator may reduce our interconnect tariffs which, in turn, may have a material adverse effect on our financial condition and results of operations."

Calling Party Pays

        In March 2006, the Federal Law on Communications was amended to incorporate a "calling party pays" scheme effective as of July 1, 2006. Prior to the implementation of the "calling party pays" principle, subscribers of fixed line operators could initiate calls to mobile phone users free of charge. Under the current system, fixed line operators charge their subscribers for such calls and transfer a percentage of the charge to mobile operators terminating such calls. The percentage transferred to mobile operators is regulated by the Federal Service for Supervision of Communications, Information Technologies and Mass Media and is known as the settlement rate. Any reduction of the settlement rate by the regulator could have a negative impact on our average monthly service revenues per subscriber and margins.

Communications Services rules and Mobile Number Portability

        On December 15, 2014, Government Decree No. 1342 concerning fixed and mobile services rules was adopted. This act, inter alia, has changed rules and conditions of MNP process (retaining telephone number after switching from one mobile operator to another) of certain types of legal entities and state customers. The period of switching numbers for mentioned subscribers was decreased and the procedure was simplified.

        Introduction of renewed procedure on MNP in respect of particular legal entities and state customers affects the mobile services market in Russia and leads to intensification of competition.

Regulation in Ukraine

Regulatory Authorities

        Administration of State Service on Special Communications and Information Protection of Ukraine. This body is responsible mainly for establishing and overseeing technical policies and standards in the sphere of telecommunications. Previously these functions were carried out by the State Communications Administration.

        The NCCIR.    The functions of the NCCIR were formerly carried out by the NCRC (National Commission for Communications Regulation of Ukraine). Established by a Decree of the President of Ukraine in August 2004, the NCRC was vested with the powers of the central regulatory body in the sphere of telecommunications on January 1, 2005 pursuant to the Telecommunications Law described below. It consisted of seven members and a chairperson. The NCRC commenced its activity in April 2005 when the chairperson and its members were appointed as required by the Telecommunications Law.

125

---

Table of Contents

        The NCRC has been responsible for issuing licenses for telecommunications services and use of radio frequencies commencing January 1, 2005, as well as various other responsibilities of the SCA from that date. According to the amendments to the Telecommunications Law introduced in July 2011, the NCRC was replaced in August 2011 with the NCCIR, which now consists of six members and a chairperson. The NCCIR is currently responsible for issuing licenses for telecommunications services and use of radio frequencies, and other functions of former NCRC.

        The State Center for Radio Frequencies of Ukraine (the "SCRF").    While licenses for radio frequencies for wireless communications are issued by the NCCIR, SCRF is the authority responsible for all technical issues related to the use of radio frequency resources and, in such proxy, is also involved in the issuance of radio frequency licenses. In particular, the SCRF determines frequency availability and technical aspects of frequency allocation, as well as provides the NCCIR with an expert opinion in relation to each application for radio frequency. The SCRF also monitored use of the frequencies and continued monitoring compliance with the license terms and carried out physically inspections of operators and providers of telecommunications services until the establishment of the State Inspection of Communications, as described below. The SCRF also independently issues individual permissions for the use of radio-electronic and radio-emitting equipment, its development, import, sale and purchase, and maintains a data base of IMEI codes of mobile telephones.

        The State Inspection of Communications (the "SIC"), established by the new Telecommunications Law, was a division of the NCRC. The SIC was responsible for the general supervision of the telecommunications market and the use of radio frequency resources. The SIC also monitored compliance with license terms, physically inspected operators and providers of telecommunications services and, together with the SCRF, reviewed cases relating to administrative violations in the areas of telecommunications and radio frequencies. In July 2011, the SIC was abolished, and inspectors tasked with supervision were re- assigned to the NCCIR.

        The Antimonopoly Committee of Ukraine (the "AMC") is charged with the administration of competition legislation and the protection and regulation of economic competition in Ukraine, including economic competition among industry participants in the telecommunications sector.

Legislation

        The principal legislation regulating the telecommunications industry consists of the Law on Telecommunications dated November 18, 2003, (the "Telecommunications Law"), and the Radio Frequencies Law dated June 1, 2000, (the "Radio Frequencies Law").

        The Telecommunications Law provides for, among other things, equal rights for private entrepreneurs and legal entities to offer telecommunications services, fair competition and freedom of pricing. The Telecommunications Law also sets forth the legal, economic and organizational framework for the operation of companies, associations and government bodies forming part of the telecommunications networks. The licensing of telecommunications services, the requirements for equipment certification and liability for violations of Ukrainian legislation on telecommunications are also determined by this legislation. The Telecommunications Law also governs the relations between the state and local governmental bodies, telecommunications operators and users of telecommunications services and radio frequencies.

        The Telecommunications Law addresses various areas of telecommunications services in Ukraine, including numbering requirements, tariff and settlement regulations, interconnect, public telecommunications services, market access rules and licensing issuance and renewal. The Telecommunications Law also significantly expands the definition of the telecommunications services market, including in its scope Internet Protocol telecommunications, transmission of data and facsimile communications.

126

Table of Contents

        The Telecommunications Law also restructured the regulatory bodies governing the area of telecommunications. It provided for the creation of the NCRC, which, between January 1, 2005, and July 5, 2011, had been responsible for many of the functions formerly handled by the SCA. In August 2011, the NCRC was replaced with the NCCIR, which is authorized, inter alia, to issue regulations for telecommunications services, issue telecommunications licenses to operators and providers, issue frequency licenses, request information from operators, providers and authorities, impose administrative penalties and maintain the register of the operators and providers. The NCCIR is also authorized to conduct hearings and to resolve disputes among operators concerning the interconnect of telecommunications networks.

        In July 2010, the Telecommunications Law was amended with provisions on mobile number portability and national roaming obligations. In April 2013 the NCCIR (formerly NCRC) adopted regulations which allow subscribers to retain their mobile telephone numbers when switching from one mobile telecommunications operator to another.

        On August 25, 2011, the NCCIR enacted national roaming regulations. Accordingly, telecommunications operators were permitted to conclude agreements on national roaming and prescribed to provide this service as described in the regulations (e.g., must inform users on roaming prices and maintain quality of service on the same level for own subscribers and subscribers of operators with whom roaming agreements are signed). Foreign investments in Ukrainian telecommunications operators are not limited; however, in order to provide telecommunications services in Ukraine an entity must be located on the territory of Ukraine and registered in accordance with Ukrainian legislation.

        The Radio Frequencies Law sets forth comprehensive rules regarding the allocation, assignment, interrelation and use of radio frequencies, the licensing of the users of radio frequencies and other relevant issues.

Licensing of Telecommunications Services and Radio Frequency Allocation

        Commencing January 1, 2005, the NCCIR (formerly NCRC) has assumed responsibility for issuing telecommunications licenses and frequency licenses pursuant to the Telecommunications Law and the 2004 amendments to the Radio Frequencies Law. Licenses are issued for the following types of telecommunications services:

•

fixed-line telephone communications services (local, intercity, international);



•

fixed-wireless telephone communications services (local, intercity, international);



•

mobile telephone communications services; and



•

technical maintenance and exploitation of telecommunications networks.

        Starting from July 5, 2011, the leasing of electric communications channels no longer requires licensing.

        Other telecommunications services do not require licenses.

        An operator that is granted a telecommunications license may not commence the provision of wireless telecommunications services until it receives a frequency license. The issuance of a frequency license is, in turn, subject to the availability of radio frequencies in the respective regions of Ukraine. Frequency licenses are issued for specific bandwidths within certain frequency spectrums in specific regions. The GSM and UMTS spectrum is presently considered to be the most commercially attractive for telecommunications operators. It is currently deemed to be virtually impossible to obtain a license for GSM frequencies in major Ukrainian cities because most of the GSM radio frequencies in such

127

---

Table of Contents

cities are already licensed to the existing GSM operators, including us. UMTS radio frequencies are currently allocated for special users, in particular, the Ministry of Defense.

        Under applicable legislation, licenses for telecommunications services may be issued and renewed for periods of not less than 5 years, with the actual period generally ranging from 10 to 15 years. Renewal of a license is made by an application submitted to the NCCIR at least four months prior to the expiration of the license term. NCCIR officials have broad discretion with respect to both the issuance and the renewal of licenses. The Telecommunications Law further provides that the NCCIR must grant licenses on a first come-first served basis within 30 days from submission of an application. If resources are limited or consumer interests so require, the NCCIR may adopt a decision to limit the number of licenses. In this event, the law requires that such decision is made public along with the rationale and that the licenses be allocated through a tender.

        In accordance with the Radio Frequencies Law, the NCCIR issues a frequency license concurrently with the issuance of a telecommunications license for the type of services requiring use of radio frequency resources. A telecommunications operator that has the respective telecommunications license may apply for licenses for additional radio frequency bands. Frequency licenses may not be issued for a period shorter than the term of the relevant telecommunications license.

        Under applicable legislation, a public tender or an auction for a radio frequency license must be held by the NCCIR if demand for radio frequency resources exceeds available resources. Radio frequency licenses issued on the basis of a public tender or an auction for the same type of radio technology must include identical conditions regarding the radio frequency bands and development period. Telecommunications operators are allowed to apply to the NCCIR for redistribution of the radio frequency resources previously allocated to them.

        Applicable legislation prohibits the transfer of a license by the licensee, including by means of assignment or pledge of a license as collateral, and agreements regarding the provision of telecommunications services must be executed and performed by the actual licensee.

        Licenses generally contain a number of detailed conditions, including the date by which service must be commenced, terms of network deployment and territory coverage, the requirement to use only certified equipment, the technical standards which must be considered and the requirement to comply with all environmental regulations. Frequency licenses issued after January 1, 2005 also contain the date by which the radio frequency resources must be fully utilized.

        Telecommunications operators' activities are subject to strict regulations, especially regarding electromagnetic compatibility; construction and technical maintenance of a telecommunications network must be carried out in accordance with specific regulations applicable in Ukraine. Telecommunications operators must submit periodic reports to the NCCIR on the amount and quality of services provided under the telecommunications license. We believe that we are in compliance with the applicable laws and regulations related to our Ukrainian licenses.

        Some licenses also provide that services for persons entitled to certain social benefits must be provided at or below certain minimum thresholds established by Ukrainian legislation in effect at that time.

        If the terms of a license are not fulfilled or the service provider violates legislation, the license may be suspended or terminated. Both telecommunications services licenses and radio frequency licenses may be terminated for various reasons, including:

•

provision of inaccurate information in the application for a license;



•

repeated refusal to allow the representatives of the NCCIR to make inspections;

128

Table of Contents

•

failure to remedy in a timely manner the circumstances which resulted in a violation of the license terms;



•

repeated violation of the license terms;



•

transfer or assignment of the license to a third party; and



•

other grounds set forth by Ukrainian laws.

        Radio frequency licenses may also be terminated for the following reasons:

•

failure to commence using radio frequency resources within the time period specified in the license;



•

termination of use of radio frequency resources specified in the license for more than one year;



•

failure to use radio frequency resources to the full extent within the time period specified in the license; and



•

failure to pay monthly fees for the use of allocated radio frequencies for six months or more.

        Decisions of the NCCIR with respect to the termination of licenses may be appealed to a court.

        MTS' Ukraine license to construct and maintain the telecommunication network and provide services using such network was due to expire on December 3, 2013. In October 2013, MTS Ukraine submitted an application to the NCCIR requesting the renewal of the license. On October 15, 2013, the NCCIR refused to renew the license and recommended that MTS Ukraine receive a new license to provide operations in the telecommunications sphere. On October 21, 2013, MTS Ukraine filed a lawsuit against the NCCIR with a demand to renew the license. On November 19, 2013, a court decision was issued in favour of MTS Ukraine. The decision obliged the NCCIR to renew the license. The NCCIR appealed against the court decision. On January 15, 2014, the court of appeal issued a judgement in which the court refused to sustain the NCCIR appeal. On January 28, 2014, the NCCIR renewed MTS Ukraine license until December, 2018. On January 27, 2014, the NCCIR filed an appeal against the court of appeals' order which was denied by the Court. The cassation procedure was started by Court of Cassation. According to decision of the Highest Administrative Court dated January 22, 2015, the satisfaction of claim dated November 19, 2013 in favor of MTS Ukraine was denied making the resolution of January 28, 2014 to prolong the license for MTS Ukraine illegitimate.

        At the same time MTS Ukraine has bought new license for providing all available mobile services in 2G and 3G networks and NCCIR issued a license for MTS Ukraine as of January 27, 2015, which is valid until 2030. In case of canceling the previous license (as prolonged by resolution of January 28, 2014), MTS Ukraine has the right to provide mobile services using the new one.

        In accordance with the terms of obtaining a license for 3G frequency, MTS Ukraine has signed conversion agreements with special users of radio frequency resource. Within an 18-month period MTS plans to expand its 3G network in all regional centers of Ukraine. Currently, MTS Ukraine complies with all license requirements and makes all necessary payments under the license.

4G/LTE

        Under the instruction of the President of Ukraine on the introduction of 4G network, the Cabinet of Ministers adopted a decree "On approval of the action plan for introduction of mobile communication of the fourth generation." The decree establishes a tender process for 4G frequency in the second half of 2017. However in order to proceed with the tender, a research and analysis of the existing radio frequency resources is required to be carried out. This research will be assigned to foreign consultants with payment to be imposed on telecommunications operators.

Equipment Certification

        For installation on a telecommunications network either the manufacturer or the vendor must provide the operator with a document of confirmation to the normative documents compliance and documentary confirmation of inclusion in the registry of technical equipment that can be used in the telecommunication network. The Administration of State Service on Special Communications and Information Protection of Ukraine sets the technical standards for equipment designed for use in telecommunications networks in Ukraine.

        The Radio Frequencies Law provides that users of radio frequency resources must obtain permits for the operation of radio-electronic and radio-emitting equipment, except for equipment used on a permit-free basis in accordance with this law. In order to obtain such operation permit, a company is required to file an application with the SCRF. The Radio Frequencies Law also requires producers and importers of radio-electronic and radio-emitting equipment to be used on the territory of Ukraine to register such equipment with the NCCIR.

Competition

        The Telecommunications Law provides that one of the purposes of the licensing of telecommunications services is to encourage competition and de-monopolization in the telecommunications industry.

        Ukrainian antimonopoly legislation prohibits a company operating in Ukraine from abusing its dominant position in its market to gain, inter alia, an unfair or anti-competitive advantage in the provision of its services or products. A legal entity is deemed to be in a dominant position if such entity has no competitor in the market or is not subject to substantial competition due to restricted access or entry barriers for other business entities. Further, Ukrainian antimonopoly legislation provides that a company shall be deemed dominant if its market share in the respective product market exceeds 35% unless such company proves that it faces significant competition in the respective product market.

        According to AC&M-Consulting, MTS Ukraine had a 34.8% market share of the wireless communications market in Ukraine as of December 31, 2015.

        A telecommunications operator which is found by the AMC to have a dominant position in the market, in particular, may specifically be required to:

•

annually submit to the NCCIR irrevocable public offers regarding interconnect with the other operators' telecommunications networks;



•

comply with the regulations of the NCCIR regarding the technical, organizational and commercial terms and conditions of interconnect with the other operators' telecommunications networks;



•

comply with the cost determination factors set by the NCCIR for access to the operator's own network; and



•

not discriminate other players in the telecommunications market.

        Please see also "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Business—A finding by the AMC that we have acted in contravention of antimonopoly legislation could have a material adverse effect on our business, financial condition and results of operations" for details of the AMC investigations in respect of international roaming services and national mobile communications services.

Tariffs

        According to the Ukrainian laws, NCCIR regulates the following tariffs:

•

maximum tariffs on public telecommunication services;



•

tariffs on leasing of communication channels for operators with dominant market position; and



•

maximum tariffs on leasing channels of cable duct system; and



•

calculation rates for services of crossing traffic to the telecommunication networks of telecommunications operators with substantial market advantage on the markets of certain telecommunication services.

        Under the Law of Ukraine on Telecommunications the Cabinet of Ministers of Ukraine is not authorized to regulate prices for telecommunication services.

        Although there are no additional regulations limiting level of maximum tariffs on wireless telecommunications services, if the Antimonopoly Committee believes competition laws are violated, it can assert that tariffs unfair and injurious to market competition. In such cases, the AMC may, inter alia, request the telecommunications operator whom AMC considers as one violating the laws to remedy the situation, in particular, to amend its tariff scheme, and impose fines on the company for an violation.

        Subject to the above, wireless operators are free to set tariffs at levels they consider appropriate.

Interconnect

        Interconnect activity is regulated by the NCCIR. Operators may provide offers for interconnect to the NCCIR, and the NCCIR is required to publish on an annual or regular basis a catalog of such offers. Operators with a dominant position on the market and operators having significant market power (SMP-operators) are obliged to submit interconnect offers to the NCCIR for each catalog.

        Interconnect is made pursuant to interconnect agreements between network operators as prescribed by the regulatory authorities. Such agreements are required under the law to contain certain provisions. An operator with a dominant position, as well as SMP-operator, cannot refuse an offer to conclude an interconnect agreement with another operator, if the offeror has offered points of interconnect that were previously published by the NCCIR in the catalog of interconnect proposals.

        The NCCIR is authorized to conduct hearings and to resolve disputes among operators concerning the interconnection of telecommunications networks. Decisions of the NCCIR are binding upon the parties in the dispute but a party to the dispute may appeal such a decision in court.

        In May 2009, the AMC issued a finding that eight mobile operators, including MTS Ukraine and its closest competitors, have a dominant position in relation to the market for interconnecting to each of their respective networks. In February 2010, the NCRC established regulated interconnect fees for termination of calls on the networks of operators that have a dominant position. See "—Competition."

        In October 2011, the NCCIR defined all of operators, including MTS Ukraine, that have operated in the Ukrainian market in the period from 2009 through 2010 as having significant market power for termination traffic on their fixed and mobile networks. Effective 1 January 2012, the NCCIR regulates the interconnection rates for all SMP fixed and mobile operators, including MTS Ukraine. The interconnection rates charged by long-distance operators are set up equal to rates charged by mobile operators.

        The NCCIR regularly analyses the telecommunication market to determine operators with significant market power in this market. In October 2015, the NCCIR published the results of the latest market analysis according to which 276 fixed and all six mobile operators, including MTS Ukraine,

131

Table of Contents

were defined as SMP-operators. Effective 1 October 2015, the NCCIR established new interconnect rates for termination traffic on the networks of SMP-operators. As a result that the interconnect rates decreased from 0.36 UAH (1.09 RUB) to 0.23UAH (0.70 RUB) for long- distance and mobile operators. Please see also "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Business—If we cannot interconnect cost-effectively with other telecommunications operators, we may be unable to provide services at competitive prices and therefore lose market share and revenues" for details of NCCIR' s plans to substantially lower interconnect rates for the termination of traffic.

6 Ostrovitjanova Street, 2 Mozhayskoe shosse, which we use for administration, sales and other service centers as well as the operations of mobile switching centers.

        We also lease buildings in Moscow for similar purposes, including marketing and sales and other service centers. In addition, through our subsidiary MGTS, we own approximately 105 buildings located throughout Moscow, which serve as sales and customer service offices, house MGTS' telecommunication equipment and are leased to third parties. We also own office buildings in some of our regional license areas and in Ukraine, and we lease office space on an as- needed basis. We believe that our properties are adequate for our current needs and additional space is available to us if and when it is needed.

        The primary elements of our network are base stations, base station controllers, transcoders and mobile switching centers. Base stations occupy sites leased at selected locations in all the areas in which we provide network coverage. GSM, 3G and 4G technologies are based on an "open architecture," which means that equipment from one supplier can be combined with that of another supplier to expand the network. Thus, there are no technical limitations to using equipment from other suppliers.

Item 5.    Operating and Financial Review and Prospects

        The following discussion of our financial condition and results of operations is intended to help the reader understand us, our operations and our present business environment and should be read in conjunction with our consolidated financial statements, related notes and other information included elsewhere in this document. In particular, we refer you to the risks discussed in "Item 3. Key Information—D. Risk Factors" for information regarding governmental, economic, fiscal, monetary or political policies or factors that could materially adversely affect our operations or your investment in our shares and ADSs. In addition, this section contains forward-looking statements that involve risk and uncertainties. Our actual results may differ materially from those discussed in forward-looking statements as a result of various factors, including those described under "Item 3. Key Information—D. Risk Factors" and "Cautionary Statement Regarding Forward-Looking Statements." Our reporting currency is the Russian ruble and our consolidated financial statements have been prepared in accordance with IFRS.

        Since these are our first consolidated financial statements prepared in accordance with IFRS, pursuant to the transitional relief granted by the SEC in respect of the first time adoption of IFRS, the following is limited to a discussion of our financial results of operations for the years ended December 31, 2015 and 2014. Refer to Note 4 to our consolidated financial statements for an explanation of how the transition from U.S. GAAP to IFRS has affected the reported financial position, financial performance and cash flows of our Company.

A.    Operating Results

Overview

        We are a leading telecommunications provider in Russia and the CIS, providing a wide range of mobile and fixed line voice and data telecommunications services, including transmission, broadband, pay-TV and various value-added services, as well as selling equipment and accessories.

        According to AC&M-Consulting, we are the largest mobile operator in Russia and the second largest in Ukraine in terms of mobile subscribers. We are also the largest operator in Armenia in terms of mobile subscribers, according to our estimates. As of December 31, 2015, we had a mobile subscriber base of approximately 102.5 million.

149

Table of Contents

        We are also the largest operator in the Moscow residential broadband market in terms of subscribers, with a 30.0% market share as of December 31, 2015, based on TMT consulting data.

        Our revenues for the year ended December 31, 2015, were RUB 431,232 million, an increase of 5.0% from the year ended December 31, 2014. Our profit attributable to the Group for the year ended December 31, 2015, was RUB 49,489 million, a decrease of 3.5% from the year ended December 31, 2014. Our profit for the year ended December 31, 2015 decreased by RUB 4,092 million or 7.9% to RUB 47,404 million. The decline in the profit resulted mainly from the following factors: impairment of goodwill in Armenia (RUB 3,516 million), increased loss from renewed operations in Uzbekistan (RUB 5,677 million), one-off gain from reentrance into Uzbekistan recognized in 2014 (RUB 6,734 million), higher finance cost (RUB 9,370 million) and increased depreciation and amortization expense (RUB 3,110 million, net of Uzbekistan amount). The described negative effects were partially offset by lower write off of investments in distressed Ukrainian banks (RUB 3,440 million), decrease in currency exchange and translation loss (RUB 11,698 million), higher finance income (RUB 3,849 million), lower non-operating share of loss of associates (RUB 2,757 million, thereof RUB 3,225 million impairment of investment in MTS Bank recognized in 2014), positive change in fair value of liability related to put option agreement in Armenia (RUB 1,273 million). Our revenues have historically increased through organic growth, as well as through acquisitions.

        We also aggressively expanded our proprietary retail and distribution network over the course of 2014 and 2015.

        We require significant funds to support our subscriber growth, primarily for increasing network capacity, maintaining and modernizing our mobile and fixed line networks, developing our network in the regions and continuing the build-out of our LTE, 3G and broadband Internet networks.

        Our cash outlays for capital expenditures (consisting of purchases of property, plant and equipment and intangible assets) for the years ended December 31, 2014 and 2015 were RUB 91,929 and RUB 106,537 million, respectively.

        We have financed our cash requirements through our operating cash flows and borrowings. Net cash provided by operating activities from continuing operations for the years ended December 31, 2014 and 2015 was RUB 158,979 million and RUB 144,087 million, respectively.

        Our borrowings consist of notes and bank loans. Our notes comprise of U.S. dollar and ruble denominated notes in the amount of RUB 76.1 billion and RUB 23.9 billion, respectively. Our bank loans consist of U.S. dollar, euro and ruble-denominated borrowings totaling approximately RUB 234.0 billion as of December 31, 2015.

        We repaid approximately RUB 51.2 billion of indebtedness in 2015. As of December 31, 2015, the total amount available to us under our credit facilities amounted to RUB 70.5 billion. We had total indebtedness of approximately RUB 345.9 billion as of December 31, 2015, including capital lease obligations, compared to approximately RUB 290.0 billion as of December 31, 2014.

        Our total interest expense for the years ended December 31, 2014 and 2015 was RUB 17,260 million and RUB 26,630 million, net of amounts capitalized, respectively. See Note 16 to our audited consolidated financial statements for a description of our indebtedness.

        Our reporting currency is Russian rubles. Our and our subsidiaries' functional currencies are the ruble in Russia, the hryvnia in Ukraine, the som in Uzbekistan, the manat in Turkmenistan and the dram in Armenia.

Segments

        Management analyzes and reviews results of the Company's operating segments separately based on the nature of products and services, regulatory environments and geographic areas. MTS Group's management evaluates the segments' performance based on revenue and operating profit. Management does not analyze assets or liabilities by reportable segments.

        The Group identified the following reportable segments:

        Russia convergent:    represents the results of mobile and fixed line operations, which encompasses services rendered to customers across regions of Russia, including voice and data services, transmission, broadband, pay-TV and various value-added services.

        Moscow fixed line:    represents the results of fixed line operations carried out in Moscow by the Group's subsidiary MGTS. MGTS is the only licensed PSTN operator in Moscow and is considered a natural monopoly under Russian antimonopoly regulations. Consequently, substantial part of services provided by MGTS are subject to governmental regulation.

        Ukraine:    represents the results of mobile and fixed line operations carried out across multiple regions of Ukraine.

        The "Other" category does not constitute a reportable segment. It includes the results of a number of other operating segments that do not meet the quantitative thresholds for separate reporting, such as Armenia, Uzbekistan, Turkmenistan, Satellite TV, Belarus and the headquarters. See also Note 26 to our audited consolidated financial statements for segment information.

        The net operating revenues of our segments for the years ended December 31, 2014 and 2015 were as follows:

Certain Operating Data

        Below we provide certain operating data not included in our financial statements that we believe is useful for evaluating our business and results. The data focuses primarily on our mobile operations, particularly in Russia and Ukraine, which comprise the most significant share of our revenue in the periods presented, and is among the information routinely reviewed by our management as part of their regular evaluation of our performance.

Mobile Subscriber Data

        The following table shows our mobile subscribers by country as of the dates indicated:

        We had approximately 77.3 million subscribers in Russia as of December 31, 2015, and a leading 31% market share of total mobile cellular subscribers in Russia, according to AC&M-Consulting. Overall penetration in Russia was at approximately 171.9%, according to our estimates. We had approximately 20.4 million subscribers in Ukraine as of December 31, 2015 and, according to AC&M-Consulting, a 34.8% market share of total mobile cellular subscribers in Ukraine. In addition, as of December 31, 2015, we had approximately 2.1 million subscribers in Armenia, and 1.6 million subscribers in Turkmenistan, representing a 59% and 30% market share, respectively, according to our estimates. For a description of our fixed line subscriber base, see "Item 4. Information on Our Company—B. Business Overview—Fixed Line Services."

Mobile churn rate

        We define mobile churn as the total number of subscribers who cease to be a subscriber during the period (whether involuntarily due to non-payment or voluntarily, at such subscriber's request), expressed as a percentage of the average number of our subscribers during that period. We view the subscriber churn as a measure of market competition and customer dynamics. The following table shows our Russian and Ukrainian subscriber churn for the periods indicated.

        The churn rate is highly dependent on competition in our license areas and those subscribers who migrate as a result of such competition.

        A vast majority of our subscribers are prepaid subscribers with no contractual commitment to us. As a result, these subscribers have unfettered freedom to migrate between operators at their

152

Table of Contents

convenience. This freedom, combined with the relative ease with which subscribers can obtain SIM cards, contributes to churn and increasing penetration levels in the markets where we operate.

        Our churn rate in Russia slightly decreased to 39.6% during the year ended December 31, 2015, as compared to 41.0% for the year ended December 31, 2014 as we improved the quality of customer service. We continued to offer our popular tariff plan "Super MTS" (free calls to all subscribers of MTS Russia) and "Smart" (integrated voice and data bundles), updated options for unlimited mobile Internet, further improved network quality and enhanced data rate by expanding our 3G and LTE capabilities. We expect that the extension of the MTS-Bonus loyalty program and further development of our mono-brand retail network will allow us to keep churn rate under control in 2016, stimulate value-added services usage and promote subscriber loyalty through superior customer service.

        The churn rate in Ukraine decreased significantly to 24.5% for the year ended December 31, 2015, from 34.2% for the year ended December 31, 2014 due to the start of 3G services at the territory of Ukraine and partnership with Vodafone. In 2016, we expect the growth of subscriber loyalty due to further service quality improvement achieved through our partnership with Vodafone.

Mobile ARPU

        We calculate mobile average monthly service revenue per subscriber by dividing our service revenues for a given period, including interconnect, guest roaming fees and connection fees, by the average number of our subscribers during that period and dividing by the number of months in that period. The following table shows our average monthly service revenue per Russian and Ukrainian subscriber based on our current calculation methodology and average monthly minutes of use per Russian and Ukrainian subscriber for the periods indicated.

        Average monthly service revenue per subscriber in Russia decreased to RUB 325.7 for the year ended December 31, 2015, from RUB 338.2 for the year ended December 31, 2014 due to tariffs reduction followed by adverse changes in macro—economic situation and decrease in the disposable income of the general population. Average monthly minutes of use per subscriber in Russia increased to 381 minutes in 2015 from 372 minutes in 2014 mainly due to decrease in tariffs for on- net traffic and various roaming-related offers.

        In Ukraine, average monthly service revenue per subscriber decreased to RUB 114.2 for the year ended December 31, 2015, from RUB 129.1 for the year ended December 31, 2014 due to depreciation of Ukrainian hryvnia against Russian rouble in 2015. The average monthly minutes of use per subscriber decreased to 508 minutes in 2015 from 554 minutes in 2014 due to the negative impact of macroeconomic factors on overall voice traffic and difficulty in provision of services in eastern Ukraine.

Revenues

        Our principal sources of revenue are:

•

mobile service revenues, which include usage and interconnect fees, value-added services fees, monthly subscription fees, roaming fees and connection fees;

153

---

Table of Contents

•

fixed service revenues from individual and corporate subscribers, which include monthly subscription fees, traffic charges, connection fees, revenues from broadband Internet connection and data transmission services, revenues from pay-TV and from sales of end-user telecommunications equipment. Fixed service revenues also include revenues received from operators, which comprise revenues from the renting out of channels and traffic charges and revenues from the renting out of telecommunications infrastructure; and



•

revenues from sales of handsets, accessories and other goods.

        Our mobile service subscriber tariffs in Russia and Ukraine are not currently regulated by any organization or governmental authority. The interconnect fees we charge to other operators for terminating calls interconnecting to our mobile network are not regulated in Russia, but are regulated in Ukraine. See also "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Business—Governmental regulation of SMP operators in Ukraine could adversely affect our results of operations," "—If we are found to have a dominant position in the markets where we operate, the government may influence our subscriber tariffs and restrict our operations" and "—If we or any of our mobile operator subsidiaries operating in Russia are identified as an operator occupying a "substantial position," the regulator may reduce our interconnect tariffs which, in turn, may have a material adverse effect on our financial condition and results of operations."

        Certain of our fixed service tariffs are regulated, including tariffs charged by Moscow incumbent operator MGTS for installation fees, monthly subscription fees and local call charges, as well as interconnect and traffic transit tariffs. The interconnect tariffs charged by us are also regulated by the Federal Agency on Communications.

Service revenues

        Usage fees include amounts charged directly to our subscribers, both for their usage of our network and for their usage of other operators' GSM networks when roaming outside of our service area. We generally bill our subscribers for all outgoing calls. Since July 2006, pursuant to an amendment to the Federal Law on Communications, mobile operators in Russia have been prohibited from charging their subscribers for incoming calls.

        The prices for outgoing calls to other cellular operators and to the public service telephone network are usually higher than charges for outgoing calls within our network. The usage fees charged for a call originating on our network depend on a number of factors, including the subscriber's tariff plan, call duration, the time of day when the call was placed and the call destination. Usage fees as a percentage of our total revenues were 23.8% in 2014 and 20.2% in 2015. Usage fees as a percentage of our total revenues have been decreasing largely due to the increase in revenues from value-added services as a percentage of our total revenues.

        Interconnect fees, which are fees for connecting users of other operators' fixed line and wireless networks to our network, comprised 12.1% and 11,5% of our total revenues in 2014 and 2015, respectively. The fluctuations of interconnect fees as a percentage of our total revenues were largely due to currency volatility and increase in revenues from value added services, which grew faster than our revenue from interconnect fees. However, in absolute terms, interconnect fees remained stable and we expect it to grow due to the increases in traffic volumes from our competitors.

        Value-added services as a percentage of our total revenues comprised 26.9% in 2014 and 29.2% in 2015. We offer our subscribers an array of value-added services. The increase in 2015 in revenue from value-added services was due to growth in data traffic, resulting from active marketing initiatives, sustained growth in customer data usage, increased data adoption through higher penetration of smartphones and tablets aided by aggressive smartphone pricing strategy in our retail chain and sustained investment in high-speed data networks.

Monthly subscription fees as a percentage of our total revenues represented 5.8% in 2014 and 7.1% in 2015. The increase in 2015 of the monthly subscription fees was due to the growth of subscribers with monthly subscription fees in the subscriber mix and the subscription-based services we offer. Many of our monthly subscription fee-based tariff plans also include a usage fee-based component for minutes used over a certain number of prepaid minutes as well as certain amount of prepaid megabytes. The percentage of our total revenues represented by usage fees as compared to monthly subscription fees will continue to be affected by changes in our tariff plans, as well as the relative product mix between usage fee-based tariff plans versus monthly subscription fee-based tariff plans.

        Roaming fees for guest subscribers include amounts charged to other cellular operators for their subscribers i.e., guest roamers, utilizing our network while traveling in our service area. We bill other cellular operators for calls of guest roamers carried on our network. Roaming fees for guest subscribers as a percentage of our total revenues remained stable and comprised 0.7% in 2014 and 2015. We generally expect that roaming fees will decline as a percentage of our total revenues due to the large increase of revenues from our value-added services. In addition, roaming tariffs between mobile operators have a tendency to decrease relative to the increase in the total number of mobile users. We may also be pressured or required to lower our roaming tariffs by FAS. See "Item 8. Financial Information—A. Consolidated Statements and Other Financial Information—7. Litigation—Antimonopoly Proceedings."

        Roaming fees for our own subscribers include amounts charged to our subscribers while traveling out of our service area. Roaming fees for own subscribers as a percentage of our total revenues represented 8.3% in 2014 and 6.9% in 2015. We expect that our roaming fees will continue to decline as a percentage of total revenues due to the continuing growth of revenues from our value-added services.

        Connection fees consist of charges incurred by subscribers for the initial connection to our network and sign-up for value-added services. We defer connection fees and recognize them as revenues over the estimated average subscriber life in our network. Connection fees represented 0.3% and 0.4% of our total revenues in 2014 and 2015, respectively. We expect connection fee revenues to remain at a low level as a percentage of our total revenues.

        Fixed service revenues which consist primarily of fixed line telephony services, broadband internet and pay-TV services, comprised 14.1% and 13.2% of our total revenues in 2014 and 2015, respectively. The decline in revenues from fixed services in 2015 is mainly attributable to the decrease in revenues from IP telephony as a result of reduced IP telephony subscribers. In absolute terms, we expect an increase in the number of internet and TV users to stimulate further growth of fixed service revenues due to the development of our GPON project and consequent improvement in quality and uptake of services provided. We expect that it will continue to grow due to the further development of GPON.

Sales of goods

        Sales of goods primary consist of the sale of handsets and accessories and as a percentage of total revenue comprised 7.0% in 2014 and 9.4% in 2015. The increase in 2015 as compared to 2014 is attributable to the promotion of sales of smartphones aimed to boost smartphone penetration and attract higher quality subscribers. We expect that sales of handsets and accessories will decrease as a percentage of total revenue due to the expected increase of revenues from our value-added services. We do not subsidize handset sales in Russia. In Ukraine, we subsidize handsets for some of our contract subscribers as well as modems for GSM and CDMA users. See "—Cost of goods" below.

Cost of Services

        Interconnect and line rental.    Interconnect and line rental charges include charges payable to other operators for access to, and use of their networks, which are necessary in the course of providing service to our subscribers. Interconnect charges as a percentage of our total revenues represented 12.6% in 2014 and 11.7% in 2015. Line rental charges as a percentage of our total revenues represented 1.9% in 2014 and 1.8% in 2015.

        We expect that interconnect expenses payable by us to other operators for termination of traffic generated by our subscribers will continue to increase. Primarily, this increase will likely be attributable to the growth in the volume of traffic resulting from our efforts to encourage greater usage through the introduction of new services, which may be supported by marketing campaigns.

        We expect line rental costs to increase based on the number of base stations, base station controllers, the number and capacity of rented lines.

        Roaming expenses.    Roaming expenses consist of amounts charged by other cellular operators under agreements for roaming services provided to our subscribers while outside our service area. Roaming expenses as a percentage of our total revenues represented 2.2% in 2014 and 3.2% in 2015. The increase of roaming expenses as a percentage of our total revenues was largely due to depreciation of Russian rouble against euro and U.S. dollar.

        Cost of value added services.    Charges for value added services include primary amounts payable to content providers. Cost of value added services as a percentage of our total revenues represented 2.1% in 2014 and 1.9% in 2015. We expect that cost of value added services will increase due to the expected increase of revenues from our value-added services.

        Other direct costs.    Our other direct costs primary consist of:

•

technical staff's salary, bonuses and social contributions;



•

rental charges for network placement;



•

network repair and maintenance;



•

electricity charges; and



•

payments for radio frequencies usage.

        Our other direct costs as a percentage of our total revenues represented 10.4% in 2014 and 11.6% in 2015. The increase is mainly attributable to rise of the salary and social contributions expenses resulting from higher number of employees (including those retained through business combinations). In addition electricity and rental charges for placement of technical facilities grew as a result of inflation and increasing number of sites rented. Other direct costs as a percentage of revenue are expected to increase over time as a result of inflation.

Cost of goods

        This type of expense includes primarily the cost of handsets and accessories sold to subscribers, and the cost of SIM cards provided to our customers. Cost of handsets, accessories sold and SIM cards provided to customers as a percentage of our total revenues represented 6.2% in 2014 and 8.5% in 2015. The increase in 2015 was primarily attributable to the growth in our handsets sales stimulated by aggressive smartphone pricing strategy aimed to counteract competitors' efforts to markedly increase their share of distribution in the market and drive further migration to higher value tariffs. We do not subsidize handset sales other than in Ukraine, where we subsidize handsets on a limited basis to contract subscribers as well as modems for CDMA users. In the years ended December 31, 2014 and

156

Table of Contents

2015 we provided net handset subsidies in Ukraine totalling RUB 67 million and RUB 26 million, respectively.

        Generally, we provide SIM cards to our customers free of charge. The cost of SIM cards amounted to RUB 1,144 million in 2014 and RUB 0,993 million in 2015.

Selling, general and administrative expenses

        Our selling expenses comprise of all costs relating to the activities that do not directly increase the value of our products and services, but serve to secure sales. These costs consist primarily of:

•

expenses for advertising and promotion;



•

dealer commissions on new connections and cash collected from subscribers; and



•

personnel, utilities and maintenance costs incurred in the area of sales.

        Selling expenses have generally increased in prior years as subscriber numbers, market saturation and market competition have increased, as well as in connection with the further development of our brand and introduction of new value-added services. In 2015, selling expenses comprised 11.9% of our total revenue, which is comparable to 11.8% in 2014.

        We retain some degree of flexibility to increase or decrease these expenses in any given period based on our requirements, strategy and the general economic environment. For the structure of our dealer commissions in Russia and Ukraine please see "Item 4. Information on Our Company—B. Business Overview—Mobile Operations—Sales and Marketing—Sales and Distribution."

        Our general and administrative expenses comprise of expenses attributable to the core administrative functions that cannot be allocated directly to the production or selling process. These consist primarily of:

•

personnel costs;



•

billing and data processing expenses;



•

taxes other than income taxes, e.g. property taxes;



•

office maintenance expenses and rental of administrative premises;



•

consulting expenses; and



•

other expenses of administrative nature.

        General and administrative expenses as a percentage of our total revenues represented 9.7% in 2014 and 8.8% in 2015. The decrease in general and administrative expense in 2015 is mainly attributable to release of our provisions for VAT and custom duties. General and administrative expenses as a percentage of revenue are expected to increase over time as a result of inflation.

Sundry Operating Income/Expenses

        Our sundry operating income/expenses include:

•

operating share of associates' profit;



•

provision for investments in distressed banks;



•

impairment for goodwill and long-lived assets;



•

gain from reentrance into Uzbekistan; and

157

Table of Contents

•

other operating expenses such as allowance for doubtful accounts, gain/losses on disposal of property, plant and equipment and intangible assets as well as any gain/losses resulting from stock-taking.

        Sundry operating income/expenses as a percentage of our total revenues represented 0.8% and 1.0% as of December 31, 2014 and 2015, respectively.

Depreciation of Property, Network Equipment and Amortization of Intangible Assets

        Our expense for depreciation of property, network equipment and amortization of intangible assets as a percentage of our total revenues increased to 19.2% for the year ended December 31, 2015 as compared to 18.2% of our total revenues for the year ended December 31, 2014. This increase was in line with our expectations, and we expect further increases in connection with our ongoing network development and modernization program and the build-out associated with our regional networks.

Interest Expense

        Our interest expense for 2015 increased by RUB 9,370 million or 54.3% compared to 2014 and amounted to RUB 26,630 million. The increase is primarily attributable to the rise in our total indebtedness and raising funds at high interest rates. We expect interest expense to increase in 2016.

Provision for Income Taxes

        Taxation on income of Russian companies is regulated by a number of laws, government decrees and implementation instructions.

        The income tax base for Russian companies is defined as income received from sales of goods and services reduced by the amount of business expenses incurred in such operations with certain exceptions.

        The statutory income tax rate in Russia is 20%. Effective April 1, 2011, the statutory income tax rate in Ukraine was reduced from 25% to 23%, to 21% in 2012, to 19% in 2013 and to 18% in 2014. As of today, no changes in tax rates are expected in the future. The effective tax rate applicable to our consolidated group in the year ended December 31, 2015 was 21.9%. The effective tax rate differs from the statutory rate insignificantly, mainly as a result of items not liable for tax purposes, earnings distributions from subsidiaries and effect of the lower tax rates of subsidiaries.

Certain Factors Affecting our Financial Position and Results of Operations

Change of reporting standards

        Beginning from January 1, 2015, we prepare our consolidated financial statements in accordance with IFRS as issued by the International Accounting Standards Board. For periods up to and including the year ended December 31, 2014, we prepared our consolidated financial statements in accordance with U.S. GAAP. The date of transition to IFRS is January 1, 2014. For details see Note 3 in our consolidated financial statements.

Change in presentation currency

        Beginning with the period commencing on January 1, 2013, we changed our reporting currency from U.S. dollar to Russian ruble. Previously, we had presented our consolidated financial statements in U.S. dollars. Our change in reporting currency is to allow better transparency of reporting.

Currency fluctuations

        A majority of our capital expenditure and a significant part of our liabilities and borrowings are either denominated in or tightly linked to the U.S. dollar or euro. We conduct our operations within the Russian Federation, Ukraine, Turkmenistan, Uzbekistan and Armenia, and we are therefore subject to currency fluctuations. The local currencies of these countries fluctuate significantly against the U.S. dollar and euro. As a result of the fluctuations we may incur significant currency exchange gains/losses which may adversely affect our net income.

Inflation

        Our financial position and results of operations as reflected in our audited consolidated financial statements included elsewhere in this document have been influenced by inflation.

        The Russian economy has been characterized by high rates of inflation:

        The Ukrainian economy has been characterized by high rates of inflation:

        Inflation rates in Armenia, Turkmenistan and Uzbekistan in 2015 were estimated at 4.3%, 5.97% and 5.6% respectively.

        We expect inflation-driven increases in costs to put pressure on our margins. While we could seek to raise our tariffs to compensate for such increase in costs, competitive pressures may not permit increases that are sufficient to preserve operating margins. See "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Financial Condition—Inflation could increase our costs and adversely affect our results of operations."

Acquisitions

        Our results of operations for the periods presented are significantly affected by acquisitions. Results of operations of acquired businesses are included in our audited consolidated financial

Year Ended December 31, 2015 compared to Year Ended December 31, 2014

Revenues and cost of services and cost of goods

        Consolidated revenues for the year ended December 31, 2015, increased by RUB 20,452 million, or 5.0%, to RUB 431,232 million from RUB 410,780 million for the year ended December 31, 2014. The principal reason for the growth of our consolidated revenues for the year ended December 31, 2015, was the large increase in the usage of value-added services by our subscribers (by RUB 15,930 million), which was mainly attributable to the increase of data traffic driven by our active promotion of value-added services, an increase in mobile internet penetration, an increase in usage of smartphones by our subscribers, active 3G and LTE network expansion and the consequent improvement of the quality and uptake of value-added services. The increase of our consolidated revenues for the year ended December 31, 2015 was also supported by the growth in revenues from sales of handsets and accessories by RUB 11,007 million and by increase of subscription revenues by RUB 6,755 million. The increase in sales of handsets and accessories by RUB 11,007 million resulted from active marketing initiatives and continued expansion of our retail operations. The growth of our subscription revenues was due to increases in the share of subscribers with monthly subscription fees in the subscriber mix and overall increase of the subscription-based services we offer.

        In the year ended December 31, 2015, we experienced a decline in our revenues from voice services by RUB 10,864 million due to continued refocusing of our strategy to promote data services. The decrease of our revenues from roaming fees of own subscribers by RUB 4,252 million in the year ended December 31, 2015 is attributable to promotion of tariff plans with reduced price per minute and overall decrease of consumption due to adverse changes in macroeconomic situation in Russia and Ukraine. Our consolidated mobile subscriber base increased and amounted to 102.5 million as of December 31, 2015 as compared to 98.8 million as of December 31, 2014. The decrease in the mobile churn rate in Russia to 39.6% from 41.0% in 2014 had an immaterial impact on our consolidated revenues.

        Consolidated cost of services and cost of goods for the year ended December 31, 2015 increased by RUB 22,154 million and amounted to RUB 167,171 million as compared to RUB 145,017 million for the year ended December 31, 2014 and comprised 38.8% and 35.3% as a percentage of consolidated revenues for the year ended December 31, 2015 and 2014, respectively. The increase was mainly attributable to the growth of cost of handsets and accessories by RUB 10,825 million, roaming expenses by RUB 4,781 million, salary and social contribution expenses by RUB 2,150 million, charges for network placement and electricity by RUB 2,725 million. The cost of handsets and accessories grew as percentage of consolidated revenues by 2,5% as a result of promoting sales of smartphones and aggressive pricing policy aimed to boost smartphone penetration. The increase in roaming expenses is mainly attributable to the appreciation of U.S. dollar and EUR against Russian ruble in the year ended December 31, 2015. The rise of the salary and social contributions resulted from the increase in number of employees. Electricity and rental charges for network placement increased due to inflation and growth of the number of rented sites.

        Russia convergent revenues for the year ended December 31, 2015, increased by 5.2% to RUB 358,360 million from RUB 340,732 million for the year ended December 31, 2014. The increase in Russia convergent revenues in the year ended December 31, 2015, was primarily due to the growth of revenues from value- added services by RUB 14,407 million, revenues from sales of handsets and accessories by RUB 11,098 million and revenues from subscription by RUB 4,650 million and revenues from Internet. Revenues from value-added services as a percentage of Russia convergent revenues in the year ended December 31, 2015, grew to 31.7% as compared to 29.1% in the year ended December 31, 2014, due to the increase in data traffic volumes attributable to the introduction of new marketing initiatives aimed at stimulating greater usage of value-added services among our subscribers and the overall improvement of quality of these services. Revenues from sales of handsets and

Table of Contents

accessories increased to RUB 40,458 million in the year ended December 31, 2015 from RUB 29,360 million in the year ended December 31, 2014 due to aggressive pricing strategy aimed to push subscribers data adoption and attract new subscribers. Revenues from subscription increased to RUB 27,147 million for the year ended December 31, 2015 from 22,496 million in the year ended December 31, 2014 as result of subscribers' migration from usage-based tariff plans to more affordable tariff plans, which include monthly subscription fees. In the year ended December 31, 2015, we experienced a decline in Russia convergent revenues from voice services by RUB 10,261 million due to continued refocusing of our strategy to promote data services. The decrease of our revenues from roaming fees from own subscribers by RUB 3,934 million as compared to the year ended December 31, 2014 is attributable to promotion of tariff plans with reduced price per minute and overall decrease of consumption due to adverse changes in macroeconomic situation in Russia.

        Russia convergent cost of services and cost of goods for the year ended December 31, 2015, increased by 13.0% to RUB 146,423 million from RUB 129,523 million for the year ended December 31, 2014. The increase of Russia convergent cost of services and cost of goods was mainly attributable to the growth of cost of handsets, accessories and other goods by RUB 11,279 million, roaming expenses by RUB 4,045 million and of salary and social contributions by RUB 1,673 million. The growth in cost of handsets, accessories and other goods resulted from the increase in volume of sales of handsets and accessories sales by 36.2% in the year ended December 31, 2015 as compared to the year ended December 31, 2014. Roaming expenses grew due to the appreciation of U.S. dollar and EUR against Russian ruble in the year ended December 31, 2015 which affected our roaming expenses in ruble terms. The rise of salary and social contribution resulted mainly from the increase in number of employees. The growth of the Russia mobile cost of services and cost of goods was offset by reduction of interconnect expenses by RUB 2,058 million due to the decline of outgoing traffic volumes and cost of value added services by RUB 755 million resulted from the change in the structure of value added services sold in favor of high margin services.

        Moscow fixed line revenues for the year ended December 31, 2015, decreased by 3.0% to RUB 39,606 million from RUB 40,824 million for the year ended December 31, 2014. The decrease in Moscow fixed line revenues in the year ended December 31, 2015, was primarily due to the decline in revenues from IP telephony by RUB 1,821 million which is attributable to the continued reduction in number of subscribers. The decrease was partially offset by the growth of other revenues, such as renting space in industrial buildings and cable line infrastructure for telecommunication equipment layout.

        Moscow fixed line cost of services and cost of goods for the year ended December 31, 2015, decreased by 2.0% to RUB 12,703 million from RUB 12,965 million for the year ended December 31, 2014. The decrease was primarily attributable to the reduction of interconnect and line rental expenses by RUB 685 million due to overall decline in outgoing traffic volume. The decrease of cost of services and cost of goods in 2015 was partially offset by growth of rent expenses by RUB 618 million as a result of rental rates indexation.

        Ukraine revenues decreased by 14.1% to RUB 28,194 million in the year ended December 31, 2015, from RUB 32,810 million in the year ended December 31, 2014, primarily due to the depreciation of Ukrainian hryvnia against Russian ruble by 16% which resulted in decrease of Ukraine revenues in ruble terms by RUB 4,576 million.

        Ukraine cost of services and cost of goods decreased by 5.1% to RUB 11,327 million in the year ended December 31, 2015, from RUB 11,941 million in the year ended December 31, 2014. The moderate decrease in ruble terms was primarily attributable to the depreciation of Ukrainian hryvnia against Russian ruble by 16% which resulted in decline of Ukraine cost of services and cost of goods by RUB 1,670 million. However, as a percentage of Ukraine revenues Ukraine cost of services and cost of goods for the year ended December 31, 2015 increased to 40.2% as compared to 36.4% for the year

Table of Contents

ended December 31, 2014. The increase was attributable to the growth in outgoing interconnect traffic volumes and related expenses by RUB 447 million and to the rise of spectrum costs by RUB 725 million.

        Other countries and business activities revenues for the year ended December 31, 2015, increased to RUB 19,193 million from RUB 11,196 million for the year ended December 31, 2014. The growth of revenue by RUB 4,443 million resulted from extending of our operations in Uzbekistan in 2015 after reentrance in September, 2014. Depreciation of Russian ruble against local currencies (Armenian dram and Turkmenian manat) caused the increase of revenue by RUB 3,914 million that was partially offset by the decline of local and international calling in Armenia driven by macroeconomic factors.

        Other countries and business activities cost of goods for the year ended December 31, 2015, increased to RUB 9,425 million from RUB 4,276 million for the year ended December 31, 2014 mainly due to extending of our operations in Uzbekistan in 2015 after reentrance in September, 2014 (RUB 3,283 million) and depreciation of Russian ruble against local currencies—Armenian dram and Turkmenian manat (RUB 1,107 million).

Sundry operating expenses

        Consolidated sundry operating expenses for the year ended December 31, 2015, increased by RUB 7,633 million to RUB 4,427 million from income of RUB 3,235 million for the year ended December 31, 2014 and comprised 1.0% and (0.8)% as a percentage of consolidated revenue for the year ended December 31, 2015 and 2014. The effect of the growth of consolidated sundry operating expenses in the year ended December 31, 2105 was caused by the lack of gain from reentrance into Uzbekistan recognized in the year ended December 31, 2014 in the amount of RUB 6,734 million (1.6% of our revenues for the year ended December 31, 2014).

        Russia convergent sundry operating expenses for the year ended December 31, 2015, increased by 125% to RUB 4,385 million from RUB 1,948 million for the year ended December 31, 2014 and comprised 1.2% and 0.6% of Russia convergent revenues for the year ended December 31, 2015 and 2014, respectively. The increase of Russia convergent sundry operating expenses was mainly attributable to the growth in bad debt provision corresponding with increase in trade receivables.

        Moscow fixed line sundry operating income for the year ended December 31, 2015, increased by RUB 1,714 million to RUB 1,842 million from RUB 127 million for the year ended December 31, 2014. Moscow fixed line sundry operating income as a percentage of Moscow fixed line revenues increased to 4.6% for the year ended December 31, 2015, from 0.3% for the year ended December 31, 2014. The increase of Moscow fixed line sundry operating income as a percentage of Moscow fixed line revenues was mainly attributable to the increase of the compensation received for cable communication lines accidentally demolished by other entities and proceeds from sale of copper cable.

        Ukraine sundry operating expenses for the year ended December 31, 2015, decreased by 64.5% or RUB 3,165 million to RUB 1,743 million from RUB 4,908 million for the year ended December 31, 2014. Ukraine sundry operating expenses as a percentage of Ukraine revenues decreased to 6.2% for the year ended December 31, 2015, from 15.0% for the year ended December 31, 2014 due to reduction of impairment charges related to distressed Ukrainian banks to RUB 1,699 million in the year ended December 31, 2015 from RUB 5,138 million in the year ended December 31, 2014.

        Other countries and business activities sundry operating (income)/expenses for the year ended December 31, 2015, increased by RUB 10,113 million to RUB 102 million from RUB 10,011 million (income) for the year ended December 31, 2014. The effect of the growth of sundry operating expenses in the year ended December 31, 2105 was caused by the lack of gain from reentrance into Uzbekistan recognized in the year ended December 31, 2014 in the amount of RUB 6,734 million and recognized

Dealer commissions as a percentage of our revenues declined to 2.1% for the year ended December 31, 2015 compared to 2.6% for the year ended December 31, 2014 mainly due to focus on proprietary retail network after cessation of cooperation with Svyaznoy. Advertising and marketing expenses increased by 16.9%, or RUB 1,421 million, to RUB 9,831 million for the year ended December 31, 2015, from RUB 8,410 million for the year ended December 31, 2014 due to the growth of the number of advertising campaigns aided to promote new services and attract subscribers. Taxes other than income tax as a percentage of our revenues declined to 0.6% for the year ended December 31, 2015 compared to 1.4% for the year ended December 31, 2014 mainly due to reversal of tax reserves for uncertain tax positions in Russia and decreasing non-taxable expenses in Ukraine.

        Russia convergent selling, general and administrative expenses for the year ended December 31, 2015, decreased to RUB 63,873 million, or 17.8% of Russia convergent revenue, from RUB 65,299 million, or 19.2% of Russia convergent revenue, for the year ended December 31, 2014. Dealer commissions as a percentage of Russia convergent revenues declined to 2.2% for the year ended December 31, 2015, compared to 2.9% for the year ended December 31, 2014 mainly due to focus on proprietary retail network after cessation of cooperation with Svyaznoy. Advertising and marketing expenses as a percentage of Russia convergent revenues increases to 2.1% for the year ended December 31, 2015, compared to 1.9% for the year ended December 31, 2014 as a result of inflation, promotion of new services and efforts to increase customer base. Salary expenses and related social contributions increased by RUB 1,846 million amounting to 7.8% of our revenues for the year ended December 31, 2015 compared to 7.7% of our revenues for the year ended December 31, 2014 due to indexation of salaries and increase in number of employees. Taxes other than income tax as a percentage of our revenues declined to 0.1% for the year ended December 31, 2015 compared to 1.0% for the year ended December 31, 2014. The decrease relates to reserves for uncertain tax positions reversed in the year ended December 31, 2015.

        Moscow fixed line selling, general and administrative expenses for the year ended December 31, 2015, increased to RUB 7,294 million, or 18.4% of Moscow fixed line revenue, from RUB 6,809 million, or 16.7% of Moscow fixed line revenue, for the year ended December 31, 2014. The increase of RUB 916 million resulted from rise in salary expenses and related social contributions from RUB 3,257 million, or 8.0% of Moscow fixed line revenue, for the year ended December 31, 2014 to RUB 4,173 million, or 10.5% of Moscow fixed line revenue, for the year ended December 31, 2015 mainly due to indexation. The growth of salary and social contribution expenses was offset by the reduction of the security and logistics expenses by RUB 215 million due to the disposal of our subsidiary Rent Nedvizhimost.

        Ukraine selling, general and administrative expenses for the year ended December 31, 2015, decreased to RUB 5,210 million from RUB 5,773 million for the year ended December 31, 2014. Decrease related to selling, general and administrative expenses in Ukraine in the amount of RUB 807 million resulted from the depreciation of the Ukrainian hryvnia against the Russian ruble.

        Other countries and business activities selling, general and administrative expenses for the year ended December 31, 2015, increased by 24.5% to RUB 14,219 million from RUB 11,417 million for the year ended December 31, 2014. The increase of Other countries and business activities selling, general and administrative expenses was mainly attributable to the growth in selling, general and administrative expenses in Uzbekistan for RUB 1,809 million due to the expansion of our operations in the country in year ended December 31, 2015.

Depreciation and amortization expenses

        Consolidated depreciation and amortization of property, network equipment, customer base, license costs and other intangible assets for the year ended December 31, 2015, increased by 9.9% to RUB 82,473 million from RUB 75,021 million for the year ended December 31, 2014. The consolidated depreciation and amortization expenses grew as a result of our reentrance to Uzbekistan in September 2014 by RUB 4,342 million and due to growth of amortization charges for intangible assets of Russia convergent by RUB 3,109 million caused by renewal of our billing and other software.

        Russia convergent depreciation and amortization for the year ended December 31, 2015, increased by 6.3% to RUB 61,271 million from RUB 57,647 million for the year ended December 31, 2014 mainly due to growth of amortization charges for intangible assets caused by renewal of our billing and other software.

        Moscow fixed line depreciation and amortization for the year ended December 31, 2015 slightly increased by 1.4% and amounted to RUB 7,715 million as compared to RUB 7,609 million for the year ended December 31, 2014. The growth resulted from the continued development of GPON project.

        Ukraine depreciation and amortization for the year ended December 31, 2015, decreased by RUB 1,580 million to RUB 5,199 million from RUB 6,779 million for the year ended December 31, 2014. The decline of RUB 947 million is attributable to the depreciation of Ukrainian hryvnia against Russian ruble.

        Other countries and business activities depreciation and amortization for the year ended December 31, 2015, increased by RUB 5,308 million to RUB 8,366 million from RUB 3,058 million for the year ended December 31, 2014. The increase is mainly attributable to the reentrance into Uzbekistan in September 2014.

Operating profit

        Consolidated operating profit declined by RUB 17,843 million from RUB 105,702 million in the year ended December 31, 2014 to RUB 87,859 million in the year December 31, 2015 mainly due to decrease in operating profit of "Other countries and business activities" segment.

        Russia convergent operating profit for the year ended December 31, 2015, declined by 4.5% to RUB 82,408 million from RUB 86,315 million for the year ended December 31, 2014. Russia convergent operating profit also decreased as a percentage of Russia convergent revenues from 25.3% for the year ended December 31, 2014, to 23.0% for the year ended December 31, 2015, due to decline of Russia convergent gross margin to 59.1% for the year ended December 31, 2015 from 62.0% for the year ended December 31, 2014. The decline of the of Russia convergent gross margin resulted from lower margin on sale of goods due to aggressive pricing policy, inflationary rise of salaries and social contributions and growth of roaming expenses due to depreciation of Russian rubles against EUR and USD.

        Moscow fixed line operating profit for the year ended December 31, 2015, increased by 1.2% to RUB 13,737 million from RUB 13,568 million for the year ended December 31, 2014.

compensation received for cable communication lines accidentally demolished by other entities and additional income from sale of copper cable.

        Ukraine operating profit for the year ended December 31, 2015, increased by 38.3% to RUB 4,715 million for the year, ended December 31, 2015 compared to RUB 3,409 million for the year ended December 31, 2014. Ukraine operating profit grew as a percentage of Ukraine revenues to 16.7% for the year ended December 31, 2015, from 10.4% for the year ended December 31, 2014. The increase of Ukraine operating profit was largely attributable to the reduction of provision for investment in distressed Ukrainian banks by RUB 3,440 million in the year ended December 31, 2015 as compared to the year ended December 31, 2014.

        Other countries and business activities operating loss for the year ended December 31, 2015, amounted to RUB 12,919 million, while other countries and business activities' operating profit for the year ended December 31, 2014, was RUB 2,456 million. The increase in operating loss is mainly attributable to impairment of goodwill in Armenia in the amount of RUB 3,516 million and change in operating loss from renewed operations in Uzbekistan by RUB 5,466 million. In addition, in the year ended December, 31 2014 we recognized a one off gain from the reentrance into Uzbekistan in the amount of RUB 6,734 million, which had a positive effect on 2014 operating profit.

Currency exchange and transaction gains/losses

        Consolidated currency exchange and transaction loss for the year ended December 31, 2015, was RUB 6,213 million, compared to the loss of 17,911 million for the year ended December 31, 2014. We conduct our operations within the Russian Federation, Ukraine, Turkmenistan, Armenia and Uzbekistan, and we are therefore subject to currency fluctuations. The local currencies of these countries fluctuated significantly against the U.S. dollar and euro during the years ended December 31, 2015 and 2014, and the currency exchange and transaction gains/losses we incurred were primarily due to the translation effect of our U.S. dollar and euro-denominated debt and deposits as of December 31, 2015 and 2014. The decreases in losses recognized in the year ended December, 31 2015 as compared to those recorded in the year ended December, 31, 2014 were mainly due to deceleration of depreciation of the Russian ruble against U.S. dollar and euro during the year ended December 31, 2015.

Interest expense

        Consolidated interest expense for the year ended December 31, 2015, increased by RUB 9,369 million, or 54.3%, to RUB 26,630 million from RUB 17,260 million for the year ended December 31, 2014, primarily as a result of the increase in our total indebtedness.

Equity in net income of associates

        Non-operating share of the profit or loss of associates for the year ended December 31, 2015 decreased by RUB 2,757 million to a loss of RUB 3,781 million compared to a loss of RUB 6,538 million for the year ended December 31, 2014. The decrease results mainly from the impairment of investment in MTS Bank in the amount of RUB 3,225 million during the year ended December 31, 2014, compensated by a larger loss at MTS Bank in the year ended December 31, 2015.

Other expenses (income), net

        Consolidated other income for the year ended December 31, 2015 increased to RUB 56 million, as compared to the expenses of RUB 936 million for the year ended December 31, 2014 due to growth of the gain on sale of foreign currencies in the year ended December, 31 2015.

Provision for income taxes

        Consolidated provision for income taxes for the year ended December 31, 2015 decreased by 17.0% to RUB 13,269 million from RUB 15,985 million for the year ended December 31, 2014 mainly as a result of decrease in income before provision for income taxes, enhanced by a decrease in the effective tax rate. The effective tax rate decreased to 21.9% in the year ended December 31, 2015, from 23.7% in the year ended December 31, 2014 mainly as a result of decrease in earnings distributions from subsidiaries, partly offset by higher level of expenses not deductible for tax purposes (in particular, impairment of goodwill in Armenia) and higher contribution of UMS loss, taxed at lower rate.

Net loss/income attributable to the non-controlling interest

        Net loss attributable to the non-controlling interest for the year ended December 31, 2015 totaled to RUB 2,085 million compared to net income attributable to the non-controlling interest of RUB 190 million for the year ended December 31, 2014. The loss is mainly attributable to the non-controlling interest in the amount of RUB 2,834 million recognized in relation to UMS, our subsidiary in Uzbekistan.

Net income attributable to the Group

        Net income attributable to the Group for the year ended December 31, 2015, decreased by RUB 1,817 million, or 3.5%, to RUB 49,489 million, compared to RUB 51,306 million for the year ended December 31, 2014. Net income as a percentage of revenues was 11.5% in the year ended December 31, 2015, and 12.5% in the year ended December 31, 2014. Net income attributable to the Group for the year ended December 31, 2015, as compared to the year ended December 31, 2014, decreased primarily due the following factors: impairment of goodwill in Armenia (RUB 3,516 million), increased loss from operations in Uzbekistan (RUB 2,843 million), one-off gain from reentrance into Uzbekistan recognized in 2014 (RUB 6,734 million), higher finance cost (RUB 9,370 million) and increased depreciation and amortization expenses (RUB 3,110 million, net of Uzbekistan amount). Negative effects were partially offset by the lower amount of impairment of investments in distressed Ukrainian banks (RUB 3,440 million), decrease in currency exchange and translation loss (RUB 11,698 million), higher finance income (RUB 3,849 million), lower non-operating share of loss of associates (RUB 2,757 million, thereof RUB 3,225 million impairment of investment in MTS Bank recognized in 2014) and positive change in fair value of liability related to put option agreement in Armenia (RUB 1,273 million).

B.    Liquidity and Capital Resources

        Our borrowings consist of notes and bank loans. Since 2001, we have raised a total of $3.0 billion (RUB 92.8 billion at the date of transactions) through seven U.S. dollar-denominated unsecured bond offerings in the international capital markets, as well as ruble-denominated bonds totaling RUB 96 billion. Our bank loans consist of U.S. dollar-, euro-, Uzbek som-, Czech crown- and ruble- denominated borrowings totaling approximately RUB 234.0 billion as of December 31, 2015. We repaid approximately RUB 51.2 billion of indebtedness in 2015. As of December 31, 2015, the total amount available to us under our credit facilities amounted to RUB 70.5 billion. We had total indebtedness of approximately RUB 345.9 billion as of December 31, 2015, including capital lease obligations, compared to approximately RUB 290.0 billion as of December 31, 2014. Our total interest expense for the years ended December 31, 2014 and 2015, was RUB 17.3 billion and RUB 26.6 billion, net of amounts capitalized, respectively. See Note 16 to our audited consolidated financial statements for a description of our indebtedness.

Capital Requirements

        We need capital to finance the following:

•

capital expenditures, consisting of purchases of property, plant and equipment and intangible assets;



•

acquisitions;



•

repayment of debt and related interest payments;



•

changes in working capital; and



•

general corporate activities, including dividends.

        We anticipate that capital expenditures, acquisitions, repayment of long-term debt and dividends will represent the most significant uses of funds for several years to come.

        Our cash outlays for capital expenditures in 2014 and 2015 were RUB 91,929 million and RUB 106,537 million, respectively. We expect to continue to finance most of our capital expenditure needs through our operating cash flows, and to the extent required, to incur additional indebtedness through borrowings or additional capital raising activities. Historically, a significant portion of our capital expenditures have been related to the installation and build-out of our network and expansion into new license areas. We expect that capital expenditures will remain a large portion of our cash outflows in connection with the continued installation and build-out of our network. We expect our total capital expenditures in 2016 to be approximately 20% of our total 2015 revenue. These investments are required to support the growth in our subscriber base (i.e., to improve network capacity), to maintain and modernize our mobile and fixed line networks, to develop our network in the regions and to continue with the roll out of LTE networks throughout Russia as well as the development of our proprietary retail chain in Russia. We expect that the development of LTE networks will be among our most significant capital expenditures and require considerable management resources. See "Item 4. Information on Our Company—B. Business Overview—Mobile Operations—Services Offered—3G Technology" for additional information. Our actual capital expenditures may vary significantly from our estimates.

        In December 2014 we acquired controlling interests in a number of mobile operators in certain regions of Russia (SMARTS-Ivanovo, SMARTS-Ufa and Penza-GSM) for cash payment of RUB 2,768 million and contingent consideration payable in 18 months of RUB 100 million at acquisition date. In December 2014, we increased our interest in MTS Bank from 26.3% to 27.0% through participation in an additional share issue of MTS Bank. In April 2014, we acquired a 10.82% stake in OZON Holdings Limited through the purchase of OZON Holdings Limited's additional share issuance amounting to USD 75 million (RUB 2,702 million). In January 2015, the Group acquired 89.5% of Navigation Information Systems from Sistema for RUB 44 million. In July and December 2015, we acquired 100% share in the holding company NVision Group from subsidiaries of Sistema for RUB 11.2 billion. In December 2015, the Group increased its share in Stream from 45% to 100% for RUB 1,650 million. In February 2016, we acquired 946,347 ordinary shares of MTS Bank, placed as part of an earlier approved additional issue, for a total consideration of RUB 1,325 million.

        We also used cash provided by operating activities as well as external credit facilities to finance our capital expenditures. We plan to finance future acquisitions through operating cash flows and additional borrowings. We may continue to expand our business through acquisitions. Our cash requirements relating to potential acquisitions can vary significantly based on market opportunities.

        We expect to refinance our existing debt when it becomes due. For scheduled maturities of debt principal outstanding as of December 31, 2015 see Note 16 of our audited consolidated financial

statements.We generally use the proceeds from our financing activities for our corporate purposes and refinancing existing indebtedness.

        Sistema, which currently controls 51.46% of our total charter capital (53.46% excluding treasury shares) and consolidates our results in its financial statements, has a significant amount of outstanding debt and requires funds for debt service. These funds may come, in part, from dividends paid by its subsidiaries, including us. Our shareholders approved semi-annual dividends for 2014 in the amount of RUB 12,812 million (including dividends on treasury shares in the amount of RUB 480.5 million). Our shareholders approved annual cash dividends for the year 2014 in the amount of RUB 40,419 million (including dividends on treasury shares in the amount of RUB 1,516 million), semi-annual dividends for 2015 in the amount of RUB 11,593 million (including dividends on treasury shares in the amount of RUB 434.8 million). Dividends payable to our shareholders as of December 31, 2015, amounted to RUB 32 million.

        We generally intend to finance our dividend requirements through operating cash flows, and accordingly, our payment of dividends may make us more reliant on external sources of capital to finance our capital expenditures and acquisitions.

Capital Resources

        We plan to finance our capital requirements through a mix of operating cash flows and financing activities, as described above. Our major sources of cash have been cash provided by operations and the proceeds of our U.S. dollar-denominated and ruble-denominated note issuances and loans. We expect that these sources will continue to be our principal sources of cash in the future.

        The availability of financing is influenced by many factors, including our profitability, operating cash flows, debt levels, credit ratings, contractual restrictions and market conditions. We cannot assure you that we will be able to continue to obtain large amounts of financing in the future through debt or equity offerings, bank financings or otherwise.

        As of December 31, 2015, our outstanding indebtedness consisted of the following notes and bank loans:

Consolidated Cash Flow Summary

        A summary of our cash flows and cash outlays for capital expenditures and acquisitions of subsidiaries follows:

Table of Contents

        For the year, ended December 31, 2015, net cash provided by operating activities totaled to RUB 144,088 million, a decrease of 9.4% from the year ended December 31, 2014. The decrease resulted mainly from the increase in the amount of interest paid (by RUB 8,613 million), higher inventory purchases (by RUB 6,729 million) as well as changes in timing of settlements with customers and suppliers.

        Net cash used in investing activities in the year ended December 31, 2015 was RUB 145,356 million, an increase of 38.4% from the year ended December 31, 2014. Net cash used on purchases of property, plant and equipment and intangible assets in the year ended December 31, 2015 increased by RUB 14,608 million (thereof due to acquisition of 3G and 4G licenses in Russia and Ukraine in the amount of RUB 10,426 million). In 2015, the cash outflow relating to short term and other investments in the form of deposits and loans totaled to RUB 41,807 million, compared to cash outflow of RUB 3,176 million for 2014 (effect year on year increase in cash flow from investing activities RUB 38,631 million). Cash spent in 2014 on the acquisition of subsidiaries, amounted to RUB 2,755 million, no subsidiaries from third parties were acquired in 2015. Investments in associates decreased by RUB 7,767 million to RUB 200 thousand for the year ended December 31, 2015, from RUB 7,767 million for the year ended December, 2014 (in 2014 we acquired share in OZON for RUB 2,702 million and invested additional RUB 4,905 million in MTS Bank). In addition, in 2015 we increased cash inflow from sale of property, plant and equipment and assets held for sale by RUB 2,370 million through sale of assets of MTS Ukraine in Crimea and copper cable by MGTS.

        Net cash used in financing activities in the year ended December 31, 2015 was RUB 27,595 million, compared to RUB 33,212 million used in the year ended December 31, 2014. The decrease was mainly attributable to the lower amount of debt and notes repayment (decrease in the amount of RUB 12,238 million) offset by higher cash outflow related to purchases/sales of subsidiaries under common control (increase in the amount of RUB 5,329 million). Major cash flows under such transactions related to acquisition of NVision Group (RUB 10,181 million) and to sale of Business- and Rent Nedvizhimost to Sistema (RUB 4,281 million). In addition, our proceeds from issue of notes and loans decreased by RUB 6,014 million in comparison with 2014, however we received RUB 6,706 million as a collateral payment related to cross-currency swap agreement with Barclay.

Liquidity

        As of December 31, 2015, we had total cash and cash equivalents of RUB 33,464 million (RUB 9,646 million in rubles, RUB 12,532 million in U.S. dollars, RUB 4,937 million in euros, RUB 4,481 million in Ukrainian hryvnias, RUB 778 million in Turkmenistan manat, RUB 628 million in Uzbek som and RUB 462 million in other currencies). In addition, as of December 31, 2015, we had short-term investments of RUB 49,840 million, mostly in form of deposits in various banks as well as loan receivables. We also had RUB 70,526 million available under existing credit facilities as of December 31, 2015. For a description of our outstanding external financing, see Note 16 to our audited consolidated financial statements.

        As of December 31, 2015, we had a working capital surplus of RUB 1,107 million compared to a surplus of RUB 1,673 million as of December 31, 2014. The decrease in working capital surplus was mainly attributable to decline in cash and cash equivalents by RUB 27,946 million and increase in current borrowings by RUB 12,285 million offset by increase in short-term investments by RUB 39,898 million. We expect to repay all long-term debts as they become due from our operating cash flows or through re-financings. We believe that our working capital, together with our plans for external financing, will provide us with sufficient funds for our present requirements.

        Russian law requires that dividends can only be paid in an amount not exceeding net profits as determined under Russian accounting standards, denominated in rubles, after certain deductions. In addition, dividends may only be paid if the value of the company's net assets is not less than the sum

of the company's charter capital, the company's reserve fund and the difference between the liquidation value and the par value of the issued and outstanding preferred stock of the company, if any, as determined under Russian accounting standards. Our net income under Russian accounting standards for the years ended December 31, 2014 and 2015 that was distributable under Russian legislation amounted to RUB 28,372 million and RUB 6,688 million, respectively.

Credit Rating Discussion

        Our credit ratings impact our ability to obtain short- and long-term financing, and the cost of such financing, and credit rating downgrades may require us to prepay certain loans. In determining our credit ratings, the rating agencies consider a number of factors, including our operating cash flows, total debt outstanding, commitments, interest requirements, liquidity needs and availability of liquidity. Other factors considered may include our business strategy, the condition of our industry and our position within the industry and the strategy, activity and/or credit rating of Sistema. Although we understand that these and other factors are among those considered by the rating agencies, each agency might calculate and weigh each factor differently. See "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Business—Our controlling shareholder has the ability to take actions that may conflict with the interests of other holders of our securities."

Sales

        In 2015, our revenues in Russia increased by 4.4% and in Ukraine decreased by 14.1%. Our mobile subscriber base increased to 102.5 million subscribers as of December 31, 2015 from 98.9 million subscribers as of December 31, 2014. We expect our consolidated subscriber base to remain stable in 2016 as a result of continued marketing and advertising activity. We anticipate our consolidated revenues will increase in 2016 mainly based on growth in data usage, the development of our broadband business in the regions and growth in sales of handsets and accessories.

        Average monthly service revenue per subscriber in Russia remained relatively stable and amounted to RUB 325.7 for the year ended December 31, 2015 as compared to RUB 338.2 for the year ended December 31, 2014. Average monthly minutes of use per subscriber in Russia increased to 381 minutes in 2015 from 372 minutes in 2014 mainly due to decrease in tariffs for on-net traffic and various roaming-related offers. We expect average monthly service revenue per subscriber in Russia to remain stable in 2016 as we plan to decrease prices and stimulate growth in usage of data services. We also believe that average monthly minutes of use per subscriber will remain stable with an increase in megabytes of use per subscriber due to our efforts aimed at stimulating data usage and on-net traffic.

        In Ukraine, our subscriber base increased to approximately 20.4 million subscribers as of December 31, 2015, from 20.2 million subscribers as of December 31, 2014. The launch of 3G services

under the Vodafone brand in Ukraine was the most significant event in 2015. In 2016, we expect revenues to remain stable under the impact of the weaker macroeconomic environment.

        Our subscriber base in Armenia remained stable and amounted to 2.1 million subscribers in 2015. The average monthly service revenue per subscriber in Armenia decreased to 2,706 dram (RUB 343) from 2,993 dram (RUB 275). We expect the average monthly service revenue per subscriber in Armenia to decline mainly due to the growth of competition in these markets which may, in turn, lead to decreasing tariffs, the addition of lower-value mass market subscribers and macroeconomic trends calling for "save mode."

        Our primary operating license in Turkmenistan was resumed, and all of our operations in the country fully recommenced since October 1, 2012. Our subscriber base in Turkmenistan decreased to 1.6 million subscribers as of December 31, 2015 from 1.7 million subscribers as of December 31, 2014. We expect our subscriber base and revenues to remain stable in 2016.

        After reentrance we started operations in Uzbekistan in December 2014. Our subscriber base in Uzbekistan developed rapidly, increased to approximately 1.1 million subscribers as of December 31, 2015 from 0.2 million subscribers as of December 31, 2014. We expect our subscriber base and revenues to increase and our market position to enhance in 2016.

        Russia and Ukraine are the two largest markets for us, both in terms of subscribers and revenue. In 2015, the underlying developments within these markets remained generally positive and included high mobile penetration, strong demand for mobile services, generally positive usage trends and increased consumption of data services and value-added services. We expect growth of business activity in Russia to continue throughout 2016. We also expect that the stabilizing of the political situation in Ukraine will allow us to retain our operating indicators.

        We expect a challenging operating environment in 2016 due to continued macroeconomic and market volatility in the countries where we operate, increasing competition and significant changes in the mobile retail market in Russia. We also experienced significant exchange rate volatility and depreciation of local currencies in the countries where we operate against the U.S. dollar. The volatility and devaluation of local currencies against the U.S. dollar and/or euro may adversely affect our costs, including our non-cash foreign exchange loss due to the translation of our U.S. dollar- and euro-denominated debt. For further information on these risks, see "—A. Operating Results—Certain Factors Affecting our Financial Position and Results of Operations—Currency Fluctuations," and "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Financial Condition—Inflation could increase our costs and adversely affect our results of operations."

        However, considering current macroeconomic conditions, our management believes that we will experience medium- and long-term growth and efficiency. Due to the fact that the Russian and the Ukrainian markets are highly penetrated, we believe the next wave of revenue growth for the overall market is likely to come from customers' increasing use of data, content and other value-added services.

Churn

        We define churn as the total number of subscribers who cease to be a subscriber during the period (whether involuntarily due to non-payment or voluntarily), expressed as a percentage of the average number of our subscribers during that period.

        A vast majority of our subscribers are prepaid subscribers with no contractual commitment to us. As a result, these subscribers have unfettered freedom to migrate between operators at their convenience. This freedom, combined with the relative ease with which subscribers can obtain SIM cards, contributes to churn and increasing penetration levels in the markets where we operate.

176

Table of Contents

        The churn rate is highly dependent on competition in our license areas and those subscribers who migrate as a result of such competition. Our churn rate in Russia slightly decreased to 39.6% during the year ended December 31, 2015, as compared to 41.1% for the year ended December 31, 2014, due to growth in the number of new connections. We continued to offer our popular tariff plans "Super MTS" (free calls to all subscribers of MTS Russia) and "Smart" (integrated voice and data bundles), updated options for unlimited mobile Internet, further improved network quality and enhanced data rate through the expansion of our 3G and LTE capabilities. We expect that the extension of the MTS-Bonus loyalty program and further development of our mono-brand retail network will allow us to keep churn rate under control in 2016, stimulate data usage and promote subscriber loyalty through superior customer service.

        The churn rate in Ukraine decreased to 24.5% for the year ended December 31, 2015, from 34.2% for the year ended December 31, 2014 due to the launch of 3G services at the territory of Ukraine and partnership with Vodafone. In 2016, we expect subscriber loyalty to grow due to the launch of 3G-enabled data services with the support of our brand partnership with Vodafone.

E.    Off-balance Sheet Arrangements

        We believe that our existing off-balance sheet arrangements do not have and are not reasonably likely to have a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that is material to investors.

Obligations under derivative contracts

        We regularly enter into fixed -to-variable interest rate swap agreements to manage the exposure of changes in variable interest rate related to its debt obligations. The instruments qualify for cash flow hedge accounting under IFRS requirements. Each interest rate swap matches the exact maturity dates of the underlying debt allowing for highly-effective hedges. Interest rate swap contracts outstanding December 31, 2015 mature in 2018 and 2020.

        In addition to the above, we have also entered into several cross-currency interest rate swap agreements. These contracts hedged the risk of both interest rate and currency fluctuations and assumed periodic exchanges of both principal and interest payments from RUB-denominated amounts to USD- and euro-denominated amounts to be exchanged at a specified rate. The rate was determined by the market spot rate upon issuance. Each interest rate swap matches the exact maturity dates of the underlying debt allowing for highly-effective hedges. Cross-currency interest rate swap contracts mature in 2019-2020.

Directors are typically elected by the annual meeting of shareholders for one year until the next annual meeting of shareholders and may be re-elected an unlimited number of times.

President

        Our President is elected by the Board of Directors for a term of three years and can be reelected for an unlimited number of terms. The rights, obligations and the times and amounts of payment for the President's services are determined by a contract between him and us, as represented by our Chairman or by a person authorized by our Board of Directors. The President is responsible for day- to-day management of our activities, except for matters reserved to our shareholders or the Board of Directors and the Management Board. The President reports to the shareholders' meeting and to the Board of Directors and is responsible for carrying out decisions made by the shareholders and by the Board of Directors and the Management Board.

Dubovskov was elected as our President and CEO, starting from March 5, 2011, by the Board of Directors for a term of three years, in March 2014 his contract was extended for three more years.

The overall number of the Management Board members is approved by the Board of Directors at the proposal of the President with each member being elected by the Board upon nomination by the President. Each Board member is elected for a three year period and can be reelected an unlimited number of times.

        The President is the Chairman of the Management Board. Currently our Management Board consists of 10 members.

Disclosure Committee

        In April 2007, we established an advisory body called the Disclosure Committee.

These disclosure standards are based on principles of timeliness, accuracy and completeness. Members of the Disclosure Committee may be nominated by various divisions of MTS, willing to have representatives in the Disclosure Committee. Members are appointed by the President.

8.A.7. Litigation

Uzbekistan

        In June 2012, the authorities of the Republic of Uzbekistan commenced audits of the financial and operating activities of MTS' wholly-owned subsidiary Uzdunrobita. Further various claims for violation of tax, antimonopoly and industry legislation were made against Uzdunrobita, which resulted in significant amounts of fines and penalties, revocation of all licenses and suspension of services. Fines

191

Table of Contents

and penalties amounted to approximately RUB 18,375 million payable in equal installments over eight months.

        Uzdunrobita paid two scheduled installments in November and December 2012 totaling approximately RUB 4,583.4 million. On January 14, 2013, further to its partial payment of the third installment due in January 2013 totaling approximately RUB 481 million and constituting the remaining amount of cash held in its bank accounts, Uzdunrobita filed a petition for voluntary bankruptcy to the Tashkent Economic Court on the grounds of its inability to meet further obligations.

        Considering the adverse impact of such circumstances on the Group's ability to conduct operations in Uzbekistan, the Group tested goodwill and other long-lived assets attributable to Uzbekistan for impairment upon first receiving notification of the investigations. As a result, an impairment loss on the long-lived assets in the amount of RUB 20,037 million was recorded in the consolidated statements of profit or loss for the year ended December 31, 2012. In 2013 these losses were assigned to discontinued operations.

        On April 22, 2013, the Tashkent Economic Court declared Uzdunrobita bankrupt and initiated a liquidation process. Uzdunrobita was later liquidated. As a result the Group lost control over the subsidiary and deconsolidated Uzdunrobita.

        In 2012, the Group filed a claim against the Republic of Uzbekistan in the International Center for Settlement of Investment Disputes ("ICSID"), part of the World Bank Group, in Washington, D.C.

        In July 2014 the dispute between MTS and the Republic of Uzbekistan was resolved. The parties signed a settlement agreement (the "Settlement Agreement") and according to its terms all mutual claims were eliminated. The Settlement Agreement is governed by English law and provides for resolution of any disputes arising out of the Settlement Agreement in the International Court of Arbitration under the International Chamber of Commerce in Paris ("ICSID"). ICSID has discontinued international arbitration proceedings between us and the Republic of Uzbekistan following the submission of a joint application by both parties.

        The Republic of Uzbekistan established a legal entity, UMS, with such entity having no legal connection to the previously liquidated entity, Uzdunrobita. UMS was granted 2G, 3G and LTE licenses valid until 2029, and received frequencies, numbering capacity and other permits required for the launch of operations. On September 24, 2014, a 50.01% ownership interest in UMS was transferred to MTS by the State Unitary Enterprise Center of Radio Communications, Radio Broadcasting and Television on behalf of the Republic of Uzbekistan. We have also received certain guaranties in relation to the protection of any future investment in the Republic of Uzbekistan.

        In March 2014, we received requests for the provision of information from the SEC and the United States Department of Justice ("DOJ") relating to a currently conducted investigation of the our former subsidiary in Uzbekistan.

        In July 2015, activities related to our operations in Uzbekistan have been referenced in a civil forfeiture complaint (the "Complaint"), filed by DOJ in the U.S. District Court, Southern District of New York (Manhattan), directed at certain assets of an unnamed Uzbek government official. The Complaint alleges among other things that we and certain other parties made corrupt payments to the unnamed Uzbek official to assist their entering and operating in the Uzbekistan telecommunications market. The Complaint is solely directed towards assets held by the unnamed Uzbek official and none of our assets are affected by the Complaint.

        We continue to cooperate with these investigations. We cannot predict the outcome of the investigations, including any fines or penalties that may be imposed, and such fines or penalties could be significant.

Other litigation

        In August 2012, we received a claim regarding dismissal of international registration of four of the Group trademarks in the territory of Ukraine from an entity named MTS LLC. The claim was fully dismissed by Economic Appeal Court of Kiev in December 2013. However, in the end of 2015, following claims of MTS LLC, two regional courts of Ukraine dismissed international registration of our trademarks in the territory of Ukraine. In March 2015, we appealed the decisions of two regional courts. The appeals are being reviewed.

Tax Audits and Claims

        In the ordinary course of business, we may be party to various tax proceedings, and subject to tax claims, some of which relate to the developing markets and evolving fiscal and regulatory environments in which we operate. In the opinion of management, our liability, if any, in all pending tax proceedings or tax claims will not have a material effect on our financial condition, results of operations or liquidity. We believe that we have adequately provided for tax liabilities in the accompanying consolidated financial statements; however, the risk remains that relevant authorities could take differing positions with regard to interpretive issues and the effect could be significant. See also Note 29 to our audited consolidated financial statements.

        In January 2014, the Russian tax authorities completed a tax audit of MGTS for the years ended December 31, 2010 and 2011. Based on the results of this audit, the Russian tax authorities determined that RUB 91.0 million in additional taxes and penalties were payable by us. MGTS appealed the resolution of this assessment to the Federal Tax Service in May 2014. The Federal Tax Service partially satisfied our petition, decreasing the amount of additional taxes, penalties and fines payable by us by RUB 61.12 million. We filed an appeal for RUB 14.94 million with the Moscow Arbitrazh Court. In February 2015, the Moscow Arbitrazh Court issued a ruling to partly grant our claim, which was subsequently confirmed by the Arbitrazh Appeal Court in April 2015.

        In December 2015, the Russian tax authorities completed a tax audit of Nvision Group for the years ended December 31, 2013 and 2014.

        In November 2015, the Russian tax authorities completed a tax audit of Stream for the years ended December 31, 2012 and 2013. Based on the results of this audit, the Russian tax authorities determined that RUB 3.1 million in additional taxes and penalties were payable by us. Stream appealed the resolution of this assessment. Following the appeal, tax authorities decided to perform additional tax control procedures.

        In October 2015, the Russian tax authorities completed a tax audit of Comstar Regions for the years ended December 31, 2012 and 2013. Based on the results of this audit, the Russian tax authorities determined that RUB 17.3 in additional taxes and penalties were payable by us. In January 2016, we appealed the resolution of this assessment to the Federal Tax Service.

Antimonopoly Proceedings

        In January 2014, the FAS subdivision in the Khanty Mansiysk Autonomous region-Yugra charged Comstar-Regions with violation of antimonopoly legislation by abusing its dominant position on the Internet access market by setting different prices in different municipalities of the region. FAS also issued an order to cease the violations. On January 17, 2014, the arbitrazh court of Khanty Mansiysk Autonomous region-Yugra cancelled the decisions and the order of the FAS subdivision in the Khanty Mansiysk Autonomous region-Yugra.

        In January 2014, the FAS subdivision in the Rostov region charged MTS with violation of antimonopoly laws by setting a monopoly tariff on cable TV tariffs services in the Rostov-on-Don city. The investigation was ceased as no violation had been found in MTS actions.

        In April 2014, the FAS subdivision in Moscow charged MGTS with violation of antimonopoly laws by different pricing of network equipment lease for different consumers. In November 2015, the FAS subdivision in Moscow issued an instruction to MGTS to cease violations, which was fulfilled. MGTS appealed the decision and ruling of FAS subdivision in Moscow in the arbitrazh court in Moscow. The appeal is being reviewed.

        In December 2015, FAS has charged MTS, MegaFon and VimpelCom with violation of antimonopoly laws in respect to pricing of SMS dispatching. The investigation is currently in progress.

Risk Factors—Risks Relating to Our Business—A finding by the AMC that we have acted in contravention of antimonopoly legislation could have a material adverse effect on our business, financial condition and results of operations" for details of the AMC investigations.

8.A.8. Dividend Distribution Policy

        Our dividend policy for the years 2013, 2014 and 2015 was aimed to make dividend payments to our shareholders in the amount of at least 75% of MTS' free cash flow, but not less than RUB 40 billion. For the purposes of dividend calculation we utilized a simplified form of free cash flow—which we define as Operating Cash Flow less capital expenditures.

        On April 8, 2016, our Board of Directors approved new dividend policy which sets a target payout of RUB 25.0 - 26.0 per ordinary MTS share (RUB 50.0 - 52.0 per ADR) per calendar year. The policy guarantees a minimum payout of RUB 20.0 per ordinary MTS share (or RUB 40.0 per ADR). The new policy will cover 2016 - 2018. Payments will continue to be made on a semi-annual basis.

        Annual and semi-annual dividend payments, if any, must be recommended by Board of Directors and approved by the General Meeting of Shareholders (GM). We anticipate that any dividends we may pay in the future on the shares represented by the ADSs will be declared and paid to the depositary in rubles and will be converted into U.S. dollars by the depositary and distributed to holders of ADSs, net of the depositary's fees and expenses. Accordingly, the value of dividends received by holders of ADSs will be subject to fluctuations in the exchange rate between the ruble and the dollar.

        At a meeting held on April 8, 2016, the Board of Directors recommended that an AGM approves annual dividends of RUB 14.01 per ordinary MTS share (RUB 28.02 per ADS), or a total of

194

Table of Contents

approximately RUB 28.0 billion, based on the full-year 2015 financial results. Upon acceptance by the AGM and completion of this payment, we will have paid out up to RUB 39.6 billion based on our fiscal year 2015 financial results.

        The Board of Directors set the date for our AGM for June 23, 2016. The record date for the Company's shareholders and ADS holders entitled to participate in the AGM has been set for May 6, 2016. The Board of Directors recommended that the AGM sets the record date for shareholders and ADS holders entitled to receive dividends for the 2015 fiscal year for July 5, 2016.

B.    Significant Changes

        Liquidation of Mobile TeleSystems Finance S.A.—In February 2016, the Group's subsidiary Mobile TeleSystems Finance S.A. was liquidated. The discontinuance of Mobile TeleSystems Finance S.A. operations does not have a material effect on the Group's financial results.

        Acquisition of MTS-bank PJSC shares—On February 25, 2016 the Group acquired 946,347 ordinary shares of MTS Bank, placed as part of an earlier approved additional issue, for a total consideration of RUB 1,325 million. As a result of the transaction, the Group's share in the capital of MTS Bank decreased from 27.0% to 26.8%.

Table of Contents

Our Purpose

        Article 2.1 of our charter provides that our principal purpose is to obtain profits through the planning, marketing, establishing and operating communications network and facilities, to provide access to Internet and to render communications services on our license territories.

        We are registered with the Ministry of Taxes and Duties of the Russian Federation under the state registration number 1027700149124.

General Matters

        Pursuant to our charter, we have the right to issue registered common stock, preferred stock and other securities provided for by legal acts of the Russian Federation with respect to securities. Our capital stock currently consists of 2,066,413,562 common shares, each with a nominal value of 0.10 rubles, all of which are issued and fully paid. Under Russian legislation, charter capital refers to the aggregate nominal value of the issued and outstanding shares. We are also authorized to issue an additional 100,000,000 common shares with a nominal value of 0.10 rubles each. We have issued only common stock. No preferred shares are authorized or outstanding. Preferred stock may only be issued if corresponding amendments have been made to our charter pursuant to a resolution of the general meeting of shareholders.

        The Joint Stock Companies Law requires us to dispose of any of our shares that we acquire within one year of their acquisition or, failing that, reduce our charter capital. We refer to such shares as treasury shares for the purposes hereof. Russian legislation does not allow for the voting of such treasury shares. Any of our shares that are owned by our subsidiaries are not considered treasury shares under Russian law (i.e., they are considered outstanding shares), and our subsidiaries holding such shares are able to vote and dispose of such shares without any further corporate actions by our shareholders or Board of Directors. As of April 1, 2016, we had 29,666 treasury shares repurchased in November 2015 pursuant to our shareholders' right to demand buy-out following our decision on merger of our subsidiaries into MTS in accordance with applicable laws. In March 2016, in the course of liquidation of our wholly owned subsidiary, MTS Bermuda Ltd., we obtained 67,995,335 shares. Together with our subsidiaries we hold a total of 77,521,164 shares. See "Item 7. Major Shareholders and Related Party Transactions—A. Major Shareholders." In our consolidated financial statements prepared in accordance with IFRS, these shares are considered treasury shares (i.e., they are considered not outstanding).

        As of the date of this document, we had more than ten thousand shareholders for purposes of the Joint Stock Companies Law.

Rights Attaching to Shares

        Holders of our common stock have the right to vote at all shareholders' meetings. As required by the Joint Stock Companies Law and our charter, all shares of our common stock have the same nominal value and grant identical rights to their holders. Each fully paid share of common stock, except for treasury shares, gives its holder the right to:

•

•

•

any amendment of our charter or approval of a restated version of our charter in a manner that restricts the holder's rights; and



•

delisting of our shares from a stock exchange;



•

upon liquidation, receive a proportionate amount of our property after our obligations are fulfilled;



•

•

exercise other rights of a shareholder provided by our charter, Russian legislation and decisions of shareholders' meeting approved in accordance with its competence.

Pre-emptive Rights

        The Joint Stock Companies Law and our charter provide existing shareholders with a pre-emptive right to purchase shares or securities convertible into shares during an open subscription in the amount proportionate to their existing shareholdings. In addition, the Joint Stock Companies Law provides shareholders with a pre-emptive right to purchase shares or securities convertible into shares, in an amount proportionate to their existing shareholdings, during a closed subscription if the shareholders voted against or did not participate in the voting on the decision approving such subscription. The

198

Table of Contents

pre-emptive right does not apply to a closed subscription to the existing shareholders provided that such shareholders may each acquire a whole number of shares or securities convertible into shares being placed in an amount proportionate to their existing shareholdings. We must provide shareholders with written notice of their pre-emptive right to purchase shares and the period during which shareholders can exercise their pre-emptive rights. Such period may not be less than 45 or, under certain circumstances, 20 days. We cannot sell the shares or securities convertible into shares which are subject to the pre-emptive rights during this period.

Dividends

        The Joint Stock Companies Law and our charter set forth the procedure for determining the quarterly and annual dividends that we may distribute to our shareholders. We may declare dividends based on our first quarter, six month, nine month or annual results. Dividends are recommended to a shareholders' meeting by a majority vote of the Board of Directors and approved by the shareholders by a majority vote. A decision on quarterly, six month and nine month dividends must be taken within three months of the end of the respective quarter at the extraordinary shareholders' meeting; and a decision on annual dividends must be taken at the annual general shareholders' meeting. The dividend approved at the shareholders' meeting may not be more than the amount recommended by the Board of Directors.

        The Joint Stock Companies Law allows dividends to be declared only out of net profits calculated under RAS as long as the following conditions have been met:

•

the charter capital of the company has been paid in full;



•

the value of the company's net assets on the date of the adoption of the decision to pay dividends is not less (and would not become less as a result of the proposed dividend payment) than the sum of the company's charter capital, the company's reserve fund and the difference between the liquidation value and the par value of the issued and outstanding preferred stock of the company;



•

the company has repurchased all shares from shareholders having the right to demand repurchase; and



•

the company is not, and would not become, insolvent as the result of the proposed dividend payment.

        The Joint Stock Companies Law and the Securities Market Law have been amended on December 29, 2012 to adopt new dividend payment rules that came into force January 1, 2014. These amendments include new rules on determining the shareholders entitled to dividend distribution whereby the list of such shareholders is fixed at date determined in the decision of the General shareholders' meeting on the distribution of dividends. The date shall be not earlier than 10 days and not later than 20 days following the date of such decision. The dividends are to be paid within 25 days from such date to private shareholders registered in the share register of the company and within 10 days to nominal holders and professional managers. If shares are held on a depo account with a depository, dividends will be transferred to such shareholders by such depositary within 7 business days of receipt of funds by the depositary.

Distributions to Shareholders on Liquidation

        Under Russian legislation, liquidation of a company results in its termination without the transfer of rights and obligations to other persons as legal successors. The Joint Stock Companies Law and our charter allow us to be liquidated:

•

by a three-quarters majority vote of a shareholders' meeting; or

199

---

Table of Contents

•

by a court order.

        Following a decision to liquidate us, the right to manage our affairs would pass to a liquidation commission appointed by a shareholders' meeting. In the event of an involuntary liquidation, the court may assign the duty to liquidate the company to its shareholders. Creditors may file claims within a period to be determined by the liquidation commission, but such period must not be less than two months from the date of publication of notice of liquidation by the liquidation commission.

        The Civil Code of the Russian Federation gives creditors the following order of priority during liquidation:

•

individuals owed compensation for injuries or deaths;



•

employees and authors of intellectual property;



•

federal and local governmental entities claiming taxes and similar payments to the federal and local budgets and to non-budgetary funds; and



•

other creditors in accordance with Russian legislation.

        Claims of creditors in obligations secured by a pledge of the company's property ("secured claims") are satisfied out of the proceeds of sale of the pledged property prior to claims of any other creditors except for the creditors of the first and second priorities described above, provided that claims of such creditors arose before the pledge agreements in respect of the company's property were made. To the extent that the proceeds of sale of the pledged property are not sufficient to satisfy secured claims, the latter are satisfied simultaneously with claims of the fourth priority creditors as described above.

        The Federal Law on Insolvency (Bankruptcy), however, provides for a different order of priority for creditors' claims in the event of bankruptcy.

        The remaining assets of a company are distributed among shareholders in the following order of priority:

•

payments to repurchase shares from shareholders having the right to demand repurchase;



•

payments of declared but unpaid dividends on preferred shares and the liquidation value of the preferred shares determined by the company's charter, if any; and



•

payments to holders of common and preferred shares.

Liability of Shareholders

        The Civil Code of the Russian Federation and the Joint Stock Companies Law generally provide that shareholders in a Russian joint stock company are not liable for the obligations of a joint stock company and bear only the risk of loss of their investments. This may not be the case, however, when one company is capable of determining decisions made by another company. The company capable of determining such decisions is called an "effective parent." The company whose decisions are capable of being so determined is called an "effective subsidiary." The effective parent bears joint and several responsibility for transactions concluded by the effective subsidiary in carrying out these decisions if:

•

this decision-making capability is provided for in the charter of the effective subsidiary or in a contract between such persons, or due to majority participation of the effective parent in the charter capital of the effective subsidiary; and



•

the effective parent gives binding instructions or consent for a transaction to the effective subsidiary.

200

---

Table of Contents

        In addition, an effective parent is secondarily liable for an effective subsidiary's debts if an effective subsidiary becomes insolvent or bankrupt resulting from the act or omission of an effective parent only when the effective parent has used the right to give binding instructions, knowing that the consequence of carrying out this act or omission would be insolvency of this effective subsidiary. This is the case no matter how the effective parent's capability to determine decisions of the effective subsidiary arises, such as through ownership of voting securities or by contract. In these instances, other shareholders of the effective subsidiary may claim compensation for the effective subsidiary's losses from the effective parent that caused the effective subsidiary to take any action or fail to take any action knowing that such action or failure to take action would result in losses.

Alteration of Capital

Charter Capital Increase

        We may increase our charter capital by:

•

issuing new shares; or



•

increasing the nominal value of previously issued shares.

        A decision on any issuance of shares or securities convertible into shares by closed subscription, or an issuance by open subscription of common shares or securities convertible into common shares constituting 25% or more of the number of issued common shares, requires a three-quarters majority vote of a shareholders' meeting. Otherwise, a decision to increase the charter capital by increasing the nominal value of issued shares requires a majority vote of a shareholders' meeting. In certain circumstances provided in our charter, a decision to increase the charter capital may be taken by our Board of Directors. In addition, the issuance of shares above the number provided in our charter necessitates a charter amendment, which requires a three-quarters affirmative vote of a shareholders' meeting.

        The Joint Stock Companies Law requires that the value of newly issued shares be determined by the board of directors based on their market value but not less than their nominal value. The price of newly issued shares for existing shareholders exercising their pre-emptive right to purchase shares could be less than the price paid by third parties, but not less than 90% of the price paid by third parties. Fees paid to intermediaries may not exceed 10% of the shares placement price. The board of directors shall value any in-kind contributions for new shares, based on the appraisal report of an appraiser.

        Russian securities regulations set out detailed procedures for the issuance and registration of shares of a joint stock company. These procedures require:

•

prior registration of a share issuance with the CBR;



•

public disclosure of information relating to the share issuance; and



•

following the placement of the shares, registration and public disclosure of the results of the placement of shares.

Charter Capital Decrease; Share Buy-Backs

        The Joint Stock Companies Law does not allow a company to reduce its charter capital below the minimum charter capital required by law, which is 100,000 rubles for a public joint stock company. The Joint Stock Companies Law and our charter require that any decision to reduce our charter capital through the repurchase and cancellation of shares, be made by a majority vote of a shareholders' meeting and through reduction of the nominal value of shares, by a three-quarter majority vote of a shareholders' meeting. Additionally, within three business days of a decision to reduce our charter capital, we must notify the federal executive body in charge of the state registration of legal entities on

201

---

Table of Contents

the decision taken and publish within the same 3-day period a notice regarding the charter capital reduction, as well as a second notice one month after the first notice is published. Our creditors, whose claims arose before the decision on the charter capital decrease was taken, would then have the right to demand, within 30 days of the second publication of the notice, early termination or settlement of relevant obligations by us, as well as compensation for damages.

        The Joint Stock Companies Law and our charter allow our shareholders or the Board of Directors to authorize the repurchase of up to 10% of our shares in exchange for cash. The repurchased shares pursuant to a board decision must be resold at the market price within one year of their repurchase or, failing that, the shareholders must decide to cancel such shares and decrease the charter capital. Repurchased shares do not bear voting rights.

        Shares repurchased pursuant to a decision of our shareholders' meeting to decrease the overall number of shares are cancelled at their redemption.

        The Joint Stock Companies Law allows us to repurchase our shares only if, at the time of repurchase:

•

our charter capital is paid in full;



•

we are not and would not become, as a result of the repurchase, insolvent;



•

the value of our net assets at the time of repurchase of our shares is not less (and would not become less, as a result of the proposed repurchase) than the sum of our charter capital, the reserve fund and the difference between the liquidation value and par value of our issued and outstanding preferred shares; and



•

we have repurchased all shares from shareholders having the right to demand repurchase of their shares in accordance with Russian law, as described immediately below.

        Our subsidiaries are not restricted from purchasing our shares, and our subsidiaries can vote these shares.

        The Joint Stock Companies Law and our charter provide that our shareholders may demand repurchase of all or some of their shares as long as the shareholder demanding repurchase voted against or did not participate in the voting on the decision approving any of the following actions:

•

any reorganization;



•

the conclusion of a major transaction, as defined under Russian law (i.e., involving assets having value of more than 50% of the balance sheet value of the assets calculated under RAS); or



•

any amendment of our charter or approval of a restated version of our charter in a manner which restricts shareholders' rights; and



•

the amendment of the public company's charter which eliminates indication that the company is public, simultaneously with the decision on applying to the CBR on release from obligation to disclose information under the laws of the Russian Federation on securities and the decision on applying for delisting of shares and equity securities convertible into shares.

        We may spend up to 10% of our net assets calculated under RAS on the date of the adoption of the decision which gives rise to a share redemption demanded by the shareholders. If the value of shares in respect of which shareholders have exercised their right to demand repurchase exceeds 10% of our net assets, we will repurchase shares from each such shareholder on a pro-rata basis. Repurchase of the shares is made at a price agreed on by the board of directors, but it should not be less than the market price.

Registration and Transfer of Shares

        Russian legislation requires that a joint stock company ensures maintenance of a register of its shareholders. Ownership of our registered shares is evidenced solely by entries made in such register. Any of our shareholders may obtain an extract from our register certifying the number of shares that such shareholder holds. Registrar NIKoil OJSC had maintained our register of shareholders since May 10, 2000. In July 2014, it has been merged into Independent Registration Company JSC (known as Computershare Registrar JSC prior to October 6, 2015) which now maintains our register of shareholders by way of universal succession.

        The purchase, sale or other transfer of shares is accomplished through the registration of the transfer in the shareholder register, or the registration of the transfer with a depositary if shares are held by a depositary. The registrar or depositary may not require any documents in addition to those required by Russian legislation in order to transfer shares in the register. Refusal to register the shares in the name of the transferee or, upon request of the beneficial holder, in the name of a nominee holder, is not allowed, except in certain instances provided for by Russian legislation, and may be challenged in court.

Reserve Fund

        Russian legislation requires that each joint stock company establish a reserve fund to be used only to cover the company's losses, redeem the company's bonds and repurchase the company's shares in cases when other funds are not available. Our charter provides for a reserve fund of 15% of our charter capital, funded through mandatory annual transfers of at least 5% of our net profits until the reserve fund has reached the 15% requirement.

Disclosure of Information

        Russian securities regulations require us to make the following periodic public disclosures and filings:

•

posting on our website quarterly reports, containing information about us, our shareholders and depositary, the structure of our management bodies, the members of the board of directors, our branches and representative offices, our shares, bank accounts and auditors, important developments during the reporting quarter, and other information about our financial and business activity;



•

publishing any information (including inside information) concerning material facts and changes in our financial and business activity, including our reorganization, certain changes in the amount of our assets, decisions on share issuances, certain corporate events, such as mandatory or voluntary tender offers, record dates, certain changes in ownership and shareholding, filing of any material claim against us, obtainment or revocation of material licenses, entry into certain transactions, as well as shareholders' and certain board of directors' resolutions and certain information regarding our material subsidiaries;



•

disclosing information on various stages of share placement, issuance and registration through publication of certain data as required by the securities regulations;



•

disclosing our charter and internal corporate governance documents on our website;



•

disclosing our annual report and annual financial statements prepared in accordance with RAS;



•

posting on our website a list of our affiliated companies and individuals on a quarterly basis;



•

posting on our website a list of inside information; and



•

other information as required by applicable Russian securities legislation.

General Shareholders' Meetings

Procedure

        The powers of a shareholders' meeting are set forth in the Joint Stock Companies Law and in our charter. In a public joint stock company a shareholders' meeting may not decide on issues that are not included in the list of its competence by the Joint Stock Companies Law. Among the issues which our shareholders have the power to decide are:

•

charter amendments;



•

reorganization or liquidation;



•

election and removal of members of the board of directors;



•

determination of the amount of compensation for members of the board of directors;



•

determination of the number, nominal value, class/type of authorized shares and the rights granted by such shares;



•

changes in our charter capital;



•

appointment and removal of our independent auditor and of the members of our review commission and counting commission;



•

approval of certain interested party transactions and major transactions;



•

participation in trade or industrial groups, or other associations of commercial entities;



•

approval of certain internal documents and corporate records;



•

distribution of profits and losses, including approval of dividends;



•

redemption by the company of issued shares in cases provided by the Joint Stock Companies Law; and



•

other issues, as provided for by the Joint Stock Companies Law and our charter.

        Voting at a shareholders' meeting is generally based on the principle of one vote per share of common stock, with the exception of the election of the board of directors, which is done through cumulative voting. Decisions are generally passed by a majority vote of the voting shares present at a shareholders' meeting. However, for public joint stock companies Russian law requires a three-quarters majority vote of the voting shares present at a shareholders' meeting to approve the following:

•

charter amendments;



•

reorganization or liquidation;



•

major transactions involving assets in excess of 50% of the balance sheet value of the company's assets calculated under RAS;



•

the number, nominal value, and category (type) of authorized shares and the rights granted by such shares;



•

repurchase by the company of its issued shares;



•

any issuance of shares or securities convertible into shares of common stock by closed subscription;



•

issuance by open subscription of shares of common stock or securities convertible into common stock, in each case, constituting 25% or more of the number of issued and outstanding shares of common stock; or

204

---

Table of Contents

•

reduction of the charter capital through reduction of the nominal value of shares.

        The quorum requirement for our shareholders' meetings is met if holders of shares (or their representatives) accounting for more than 50% of the issued voting shares are present. If the 50% quorum requirement is not met, another shareholders' meeting with the same agenda may (and, in case of an annual shareholders' meeting must) be scheduled and the quorum requirement is satisfied if holders of shares (or their representatives) accounting for at least 30% of the issued voting shares are present at that meeting.

        The annual shareholders' meeting must be convened by the board of directors between March 1 and June 30 of each year, and the agenda must include the following items:

•

election of the members of the board of directors;



•

approval of the annual report and the annual financial statements, including the balance sheet and profit and loss statement;



•

approval of distribution of profits, including approval of dividends, and losses, if any;



•

appointment of an independent auditor; and



•

appointment of the members of the review commission.

        A shareholder or group of shareholders owning in the aggregate at least 2% of the issued voting shares may introduce proposals for the agenda of the annual shareholders' meeting and may nominate candidates for the board of directors, counting commission and review commission. Any agenda proposals or nominations must be provided to the company no later than 100 calendar days after the preceding financial year end.

        Extraordinary shareholders' meetings may be called by the board of directors on its own initiative, or at the request of the review commission, the independent auditor or a shareholder or group of shareholders owning in the aggregate at least 10% of the issued voting shares as of the date of the request. The decision to call or reject the call for an extraordinary shareholders' meeting shall be made by the board of directors within five days from the receipt date of the request and sent to the party that requested the meeting within three days after such a decision was made.

        A general meeting of shareholders may be held in a form of a meeting or by absentee ballot. The form of a meeting contemplates the adoption of resolutions by the general meeting of shareholders through the attendance of the shareholders or their authorized representatives for the purpose of discussing and voting on issues of the agenda, provided that if a ballot is mailed to shareholders for participation at a meeting convened in such form, the shareholders may complete and mail the ballot back to the company without personally attending the meeting. A general meeting of the shareholders by absentee ballot contemplates the determination of collecting shareholders' opinions on issues of the agenda by means of a written poll.

        The following issues cannot be decided by a shareholders' meeting by absentee ballot:

•

election of the members of the board of directors;



•

election of the review commission;



•

approval of a company's independent auditor; and



•

approval of the annual report, the annual financial statements.

Notice and Participation

        All shareholders entitled to participate in a general shareholders' meeting must be notified of the meeting, whether the meeting is to be held in the form of a meeting or by absentee ballot, no less than

205

---

Table of Contents

30 days prior to the date of the meeting, and such notification shall specify the agenda for the meeting. However, if it is an extraordinary shareholders' meeting to elect the board of directors, shareholders must be notified at least 70 days prior to the date of the meeting. Only those items that were set out in the agenda to shareholders may be voted upon at a general shareholders' meeting.

        If a nominal holder of the shares registers in the register of shareholders, then a notification of the shareholders' meeting shall be sent to the nominal holder. The nominal holder must notify its clients in accordance with Russian legislation or an agreement with the client. The list of shareholders entitled to participate in a general shareholders' meeting is to be compiled on the basis of data in our shareholders register on the date established by the board of directors, which date may neither be earlier than the 10 days after the date of adoption of the board resolution to hold a general shareholders' meeting nor more than 50 days before the date of the meeting (or, in the case of an extraordinary shareholders' meeting to elect the board of directors, not later than 80 days before the date of the meeting).

        The right to participate in a general meeting of shareholders may be exercised by a shareholder as follows:

•

by personally participating in the discussion of agenda items and voting thereon;



•

by sending an authorized representative to participate in the discussion of agenda items and to vote thereon;



•

by submitting a written ballot reflecting the shareholders' voting on the agenda items; or



•

by delegating the right to submit such written ballot to an authorized representative.

Board of Directors

        Our charter provides that our entire Board of Directors is up for election at each annual general shareholders' meeting. Our Board of Directors is elected through cumulative voting. Under cumulative voting, each shareholder may cast an aggregate number of votes equal to the number of shares held by such shareholder multiplied by the number of persons to be elected to our Board of Directors, and the shareholder may give all such votes to one candidate or spread them between two or more candidates. Before the expiration of their term, the directors may be removed as a group at any time without cause by a majority vote of a shareholders' meeting.

        The Joint Stock Companies Law requires at least a five-member board of directors for all joint stock companies, at least a seven-member board of directors for a joint stock company with more than 1,000 holders of voting shares, and at least a nine-member board of directors for a joint stock company with more than 10,000 holders of voting shares. Only natural persons (as opposed to legal entities) are entitled to sit on the board. Members of the board of directors are not required to be shareholders of the company. The actual number of directors is determined by the company's charter or a decision of the shareholders' meeting. Our charter provides that our Board of Directors consists of at least seven members, which number may be increased pursuant to a decision of the general meeting of shareholders. Currently, our Board of Directors consists of nine members.

        The Joint Stock Companies Law prohibits a board of directors from acting on issues that fall within the competence of the general shareholders' meeting. Our Board of Directors has the power to perform the general management of the company, and to decide, among others, the following issues:

•

determination of our business priorities;



•

approval of our annual plans, including financial plans;



•

convening annual and extraordinary shareholders' meetings, except in certain circumstances specified in the Joint Stock Companies Law;

•

approval of our share registrar and the terms of the agreement with it; and



•

other issues, as provided for by the Joint Stock Companies Law and our charter.

        Our charter generally requires a majority vote of the directors present for an action to pass, with the exception of actions for which Russian legislation requires a unanimous vote or a majority vote of the disinterested and independent directors, as described therein. A board meeting is considered duly assembled and legally competent to act when a majority of elected directors is present.

        Our internal regulation "On the Board of Directors of Mobile TeleSystems Public Joint Stock Company" (the "Regulation") was approved by the annual shareholders' meeting on June 25, 2015. In accordance with clause 2.2.2 of the Regulation, the members of the Board of Directors have the right to:

•

receive information regarding our operations;

Interested Party Transactions

        Under the Joint Stock Companies Law, certain transactions defined as "interested party transactions" require approval by disinterested directors or shareholders of the company. "Interested party transactions" include transactions involving a member of the board of directors or member of any executive body of the company (including the company's CEO and/or the company's managing organization), any person that owns, together with any affiliates, at least 20% of a company's issued voting shares or any person who is able to direct the actions of the company, if that person and/or that person's spouse, parents, children, adoptive parents or children, brothers or sisters and/or their affiliates, is/are:

•

a party to, or beneficiary of, a transaction with the company, whether directly or as a representative or intermediary;



•

the owner of at least 20% of the issued shares of a legal entity that is a party to, or beneficiary of, a transaction with the company, whether directly or as a representative or intermediary; or



•

a member of the board of directors or a member of any management body of a company that is a party to, or beneficiary of, a transaction with the company, whether directly or as a representative or intermediary, or a member of the board of directors or of any management body of a management organization of such a company.

        The Joint Stock Companies Law requires that an interested party transaction by a company with more than 1,000 shareholders (holders of voting shares) be approved by a majority vote of the independent directors of the company who are not interested in the transaction. For purposes of this

208

---

Table of Contents

rule, an "independent director" is a person who is not, and within the year preceding the decision to approve the transaction was not, a general director/president, a member of any executive body or an affiliate of the company, or a member of the board of directors or any management body of the company's management organization. Additionally, such person's spouse, parents, children, adoptive parents or children, brothers or sisters may not, and within the year preceding the date of the decision to approve the transaction did not, occupy positions in the executive bodies of the company or positions on the board of directors or of any management body of the company's management organization. For companies with 1,000 or fewer shareholders, an interested party transaction must be adopted by a majority vote of the directors who are not interested in the transaction if the number of these directors is sufficient to constitute a quorum.

        Approval by a majority of shareholders who are not interested in the transaction is required if:

•

the value of such transaction or a number of interrelated transactions is 2% or more of the balance sheet value of the company's assets determined under RAS;



•

the transaction or a number of interrelated transactions involves the issuance, by subscription, of voting shares or securities convertible into voting shares, or a secondary market sale of such securities, in an amount exceeding 2% of the company's issued voting stock;



•

the number of directors who are not interested in the transaction is not sufficient to constitute a quorum; or



•

all the members of the board of directors of the company are interested parties, or none of them is an independent director.

        Approval by a majority of shareholders who are not interested in the transaction may not be required, until the next annual shareholders' meeting, for an interested party transaction if such transaction is substantially similar to transactions concluded by the company and the interested party in the ordinary course of business before such party became an interested party with respect to the transaction.

        The approval of interested party transactions is not required in the following instances:

•

the company has only one shareholder that simultaneously performs the functions of the company's CEO;



•

all shareholders of the company are deemed interested in such transactions;



•

the transactions arise from the shareholders executing their preemptive rights to purchase newly issued shares of the company;



•

the transactions arise from the repurchase, whether mandatory or not, by the company of its issued shares;



•

merger transactions; or

the transactions that are mandatory for the company pursuant to Russian law and must be concluded on the basis of fixed prices and tariffs adopted by a competent state body.

Major Transactions

        The Joint Stock Companies Law defines a "major transaction" as a transaction, or a number of interrelated transactions, involving the acquisition or disposal, or a possibility of disposal (whether directly or indirectly) of property having a value of 25% or more of the balance sheet value of the assets of a company determined under RAS, with the exception of transactions conducted in the ordinary course of business, transactions involving the placement of common stock, or securities convertible into common stock or transactions to be executed by the company pursuant to the federal

209

laws and/or other regulations of the Russian Federation and priced in accordance with the regulations of the Russian government or other federal bodies authorized by the Russian government. Major transactions involving assets having a value ranging from 25% to 50% of the balance sheet value of the assets of a company determined under RAS require unanimous approval by all members of the board of directors or, failing to receive such approval, a simple majority vote of a shareholders' meeting. Major transactions involving assets having a value in excess of 50% of the balance sheet value of the assets of a company determined under RAS require a three-quarters majority vote of a shareholders' meeting.

Change in Control

Anti-takeover Protection

        Russian legislation requires the following:

•

A person intending to acquire more than 30% of a public joint stock company's ordinary shares and voting preferred shares (including, for such purposes, shares already owned by such person and its affiliates), will be entitled to make a public tender offer to other holders of such shares or securities convertible into such shares.



•

A person that has acquired more than 30% of a public joint stock company's ordinary shares and voting preferred shares (including, for such purposes, shares already owned by such person and its affiliates) will, except in certain limited circumstances, be required to make, within 35 days of acquiring such shares, a public tender offer for other shares of the same class and for securities convertible into such shares, at the price which is not less than the price determined based on a weighted average market price of the shares over the six month period before the filing of the offer with the CBR as described below, if the shares are publicly traded, or on a price supplied by an appraiser if the shares have no or insufficient trading history. The public tender offer price may not be less than the highest price at which the offeror or its affiliated persons purchased or undertook to purchase the relevant securities over the six month period before the offer was sent to the company. From the moment of acquisition of more than 30% of the shares until the date the offer was sent to the company, the person making the offer and its affiliates will be able to register for quorum purposes and vote only 30% of the company's ordinary shares and voting preferred shares (regardless of the size of their actual holdings). These rules also apply to acquisitions resulting in a person or a group of persons owning more than 50% and 75% of a company's issued ordinary shares and voting preferred shares.



•

A person that as a result of an offer described in either of the preceding paragraphs becomes (individually or with its affiliates) the owner of more than 95% of the company's ordinary shares and voting preferred shares, must buy out the remaining shares of the company as well as other securities convertible into such shares upon request of the holders of such shares or other securities, and may require such holders to sell such shares and other securities, at the price determined in the manner described in the preceding paragraph but not less than (i) the price of the preceding acquisition of the company's relevant securities under an offer described in either of the preceding paragraphs as a result of which the offeror and its affiliates acquired over 95% of the company's ordinary shares and voting preferred shares; or (ii) the highest price at which after the expiration date of an offer described in either of the preceding paragraphs the offeror or its affiliates purchased or undertook to purchase the relevant securities.



•

An offer of the kind described in either of the preceding three paragraphs must be accompanied by a bank guarantee of payment. If the company is publicly traded, prior notice of the offer must be filed with the CBR; otherwise, notice must be filed with the CBR no later than the date of the offer. The CBR may order amendments to the terms of the offer (including price) in order to bring them into compliance with the rules.

•

Once such an offer has been made, competing offers for the same securities can be made by third parties and, in certain circumstances, acceptance of the initial offer may be withdrawn by the security holders who choose to accept such competing offer. From the making of such an offer until 20 days after its expiry (which period may in certain cases exceed 100 days) the company's shareholders' meeting will have the sole power to make decisions on charter capital increase, issuance of securities, approval of certain major transactions, and on certain other significant matters.

        The above rules may be supplemented through CBR rulemaking, which may result in a wider, narrower or more specific interpretation of these rules by the government and judicial authorities, as well as by market participants.

Approval of FAS

        Pursuant to the Federal Law on Competition, until January 5, 2016, FAS had to approve in advance acquisitions of voting shares in a company involving (1) companies with a combined value of assets or combined annual revenues calculated under RAS exceeding a certain threshold, or (2) companies included in a register of business entities having more than a 35% share of a certain commodity market or otherwise occupying a dominant position on the market, and which would result in acquisition by a person (or a group of affiliates) of more than 25%, 50% or 75% of voting shares of a joint stock company, or a participation interest according 1/3, 50%, ²/3 of voting rights in a limited liability company, or in a transfer between such companies of assets or rights to assets, the value of which exceeds a certain amount. According to the amendments made by the Federal law No. 275-FZ dated October 5, 2015 starting from January 5, 2016 the regulations in relation to the abovementioned register were repealed and only the combined value of assets or combined annual revenues of the companies involved in the transaction is taken in account. See also "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Business—If we are found to have a dominant position in the markets where we operate, the government may influence our subscriber tariffs and restrict our operations."

Strategic Industries Law

        Pursuant to the Strategic Foreign Investment Law investments resulting in a foreign entity or a group of entities receiving control over a company with strategic importance for the national defense and security of the Russian Federation (a "strategic company") or acquisition of fixed production assets of a strategic company having value of at least 25% of its assets calculated under RAS require prior approval from the state authorities. The procedure for issuing such consent involves a special governmental commission on control of foreign investments, which was established by the Resolution of the Government of Russia dated July 6, 2008 as the body responsible for granting such consents, and FAS, which is authorized to process applications for consent from foreign investors. "Control" means an ability to determine, directly or indirectly, decisions taken by a strategic company, whether through voting at the general shareholders' (participants') meeting of the strategic company, participating in the board of directors or management bodies of the strategic company, or acting as the external management organization of the strategic company, or otherwise. As a result, "control" will generally be deemed to exist if an entity or a group of entities acquires more than 50% of the shares (or participation interest in share capital) of a strategic company, or if through contract or securities with voting rights it is able to appoint more than 50% of the members of the board of directors or of the management board of a strategic company.

        Furthermore, if a foreign entity or group of entities holding securities of a strategic company or other entity that exercises control over this company becomes a direct or indirect holder of voting shares in an amount that is considered to give it direct or indirect control over this company in accordance with the Strategic Foreign Investment Law due to a change in allocation of voting shares pursuant to the procedures provided by Russian law (e.g., as a result of a buy-back of its shares by the

211

---

Table of Contents

relevant company), then such entity or group of entities will have to apply for state approval of its control within three months after it received such control.

        In addition, foreign investors are required to notify this authorized governmental agency about any transactions undertaken by them resulting in the acquisition of 5% or more of the charter capital of a strategic company and other transactions or other actions preapproved in accordance with the Strategic Foreign Investment Law.

        See also "Item 3. Key Information—D. Risk Factors—Legal Risks and Uncertainties—The Strategic Foreign Investment Law imposes certain restrictions on us and our existing and potential foreign shareholders, which could have a material adverse effect on our business, financial condition, results of operations and prospects."

Disclosure of Ownership

        Under Russian law, a person acquiring, directly or indirectly, 5% or more of our common shares is required to notify us and the CBR of, and we must then publicly disclose, such acquisition, as well as any subsequent acquisitions or disposals resulting in the crossing of 5%, 10%, 15%, 20%, 25%, 30%, 50%, 75% or 95% thresholds of our outstanding common shares by such person.

        A holder of more than 5% of our common shares is required to file with us and the CBR information about its controlling shareholder (if any) or notify us and the CBR about the absence of any such controlling shareholders.

        Our subsidiaries are required to notify us and the CBR about the acquisition of our common shares. We are required to publicly disclose the acquisition of our common shares by our subsidiaries.

Notification of Foreign Ownership

        Foreign persons registered as individual entrepreneurs in Russia who acquire shares in a Russian joint stock company and foreign companies that acquire shares in a Russian joint stock company may need to notify the Russian tax authorities within one month following such acquisition. However, the procedure for notifying the Russian tax authorities by foreign companies that are not registered with such tax authorities at the time of their share acquisition remains unclear.

C.    Material Contracts

        The following is a description of contracts that we and/or our subsidiaries are a party to and that are or may be material to our business.

Eurobonds

        On May 28, 2013, we issued U.S. dollar-denominated Loan Participation Notes in the amount of $500 million (RUB 16.4 billion as of December 31, 2013) with an annual interest rate of 5.00% and a maturity in June 2023. The proceeds will be used for general corporate purposes. The notes were issued by MTS International Funding Limited, a private company organized and existing as a private limited company under the laws of Ireland, and are listed on the Irish Stock Exchange. Proceeds were on-lent to us pursuant to a loan agreement between us and MTS International Funding Limited.

        The loan agreements relating to our notes due 2023 sets forth various occurrences, each of which would constitute an event of default. If an event of default, other than an event of default arising from events of bankruptcy, insolvency or bankruptcy-related reorganization, occurs and is continuing, either the lender, the trustee or the holders of at least 25% in principal amount of the outstanding notes may accelerate the maturity of all of the notes. If an event of default arising from events of our bankruptcy, insolvency or bankruptcy-related reorganization occurs and is continuing, then the principal of, and

212

Table of Contents

accrued interest on, all of the notes will automatically become immediately due and payable without any declaration or other act on the part of the lender, holders of notes or the trustee.

        Covenants in the loan agreement relating to our notes due 2023 limit our ability to create liens on our properties, merge or consolidate with another person or convey our properties and assets to another person. In addition, if we experience certain types of mergers, consolidations or other changes in control, noteholders will have the right to require us to redeem the notes at 101% of their principal amount, plus accrued interest. We are also required to take all commercially reasonable steps necessary to maintain a rating of the notes from Moody's or Standard & Poor's. If we fail to meet these covenants, after certain notice and cure periods, the noteholders can accelerate the debt to be immediately due and payable.

Ruble bonds

        On April 3, 2013, we issued exchange-traded ruble bond on Moscow Exchange. The bond is worth RUB 10 billion and has a maturity of ten years. Coupons are to be paid semiannually at the rate of 8.25%. Bond holders will have the right under a five-year put option to sell the bonds to us. The proceeds from the bond replacement will be used for general corporate needs.

D.    Exchange Controls

        The Federal Law on Currency Regulation and Currency Control which came into effect on June 18, 2004 sets forth certain restrictions on settlements between residents of Russia with respect to operations involving foreign securities (including ADSs), including requirements for settlement in Russian rubles.

Repatriation of Export Proceeds

        Russian companies must repatriate 100% of their receivables from the export of goods and services (with a limited number of exceptions concerning, in particular, certain types of secured financing).

Restrictions on the remittance of dividends, interest or other payments to non-residents

        The Federal Law on Foreign Investments in the Russian Federation of July 9, 1999 specifically guarantees foreign investors the right to repatriate their earnings from Russian investments. However, the evolving Russian exchange control regime may materially affect your ability to do so.

        Currently, ruble dividends on common shares may be converted into U.S. dollars without restriction. However, the ability to convert rubles into U.S. dollars is also subject to the availability of U.S. dollars in Russia's currency markets. Although there is an existing market within Russia for the conversion of rubles into U.S. dollars, including the interbank currency exchange and over-the-counter and currency futures markets, the further development of this market is uncertain.

E.    Taxation

Certain Russian Tax Consequences

        The following discussion describes the material Russian corporate income tax and personal income tax consequences to you if you are a U.S. holder of ADSs and a resident of the United States for purposes of the United States—Russia income tax treaty and are fully eligible for benefits under the United States—Russia income tax treaty. Subject to certain provisions of the United States—Russia income tax treaty relating to limitations on benefits, a U.S. resident under the treaty is generally defined as a person liable, under the laws of the United States, to U.S. tax (other than taxes with respect to only of income from sources in the United States or capital situated therein) by reason of your domicile, residence, citizenship, place of incorporation, or any other similar criterion (and, for

213

Table of Contents

income derived by a partnership, trust or estate, residence is determined in accordance with the residence of the person liable to tax with respect to such income). The treaty provides for a procedure to resolve matters where a resident of the United States qualifies as a Russian tax resident under Russian domestic rules. The treaty also provides for the non-application of treaty benefits to certain types of entities.

        Additionally, the benefits under the United States—Russia income tax treaty discussed in this document generally are not available to U.S. persons who hold ADSs in connection with the conduct of a business in the Russian Federation through a permanent establishment as defined in the United States—Russia income tax treaty. Subject to certain exceptions, a U.S. person's permanent establishment under the United States—Russia income tax treaty is a fixed place of business through which such person carries on business activities in the Russian Federation (generally including, but not limited to, a place of management, a branch, an office and a factory). Under certain circumstances, a U.S. person may be deemed to have a permanent establishment in the Russian Federation as a result of activities carried on in the Russian Federation through agents of the U.S. person. This summary does not address the treatment of holders described in this paragraph.

        Treaty benefits may be potentially available to U.S. tax residents that are not subject to limitations on treaty benefits under the treaty, do not operate through a permanent establishment in Russia and are foreign legal entities (i.e., a legal entity or organization in each case not organized under Russian law) or individuals not considered Russian tax residents under Russian law. Under current Russian law, the Russian tax residency for individuals is generally determined based on the number of days a person spends in Russia in a 12-month rolling period. Law specifies that an individual present in Russia for an aggregate period of 183 days in any consecutive 12-month period will be considered as a tax resident. Since tax year in Russia is a calendar year the final tax residency status of an individual taxpayer shall still be defined for a whole calendar year by counting the days spent in Russia within that relevant calendar year. Accordingly, to be considered a Russian tax resident, the taxpayer should spend at least 183 days in Russia in a calendar year. The following discussion is based on:

•

Russian tax legislation; and



•

the United States—Russia income tax treaty (and judicial and administrative interpretations thereof by the Russian authorities);

        All of the foregoing tax consequences are based on information in effect as of the date of this document and are subject to change, possibly on a retroactive basis, after the date of this document. This discussion is also based, in part, on representations of the depositary, and assumes that each obligation in the deposit agreement and any related agreements will be performed in accordance with its terms. The discussion with respect to Russian legislation is based on our understanding of current Russian law and Russian tax rules, which are subject to frequent change and varying interpretations.

        The following discussion is not intended as tax advice to any particular investor. It is also not a complete analysis or listing of all potential Russian corporate income and personal income tax consequences to you of ownership of ADSs. We urge you to consult your own tax adviser regarding the specific Russian tax consequences of the ownership and disposition of ADSs under your own particular factual circumstances.

Specific uncertainties associated with the tax treatment of ADS holders

        The Russian tax rules in relation to ADS holders (that would affect U.S. holders) are characterized by significant uncertainties and limited interpretive guidance. Recent amendments to the tax rules have clarified the status of the ADS holders as beneficial owners of the income from the underlying shares by establishing that the custodian holding the depo account with the shares underlying the ADSs acting as the tax agent and determines amounts of the withholding tax based on the information about the

214

---

Table of Contents

ADS holders and their tax residency status as provided by the program depositary. However, the application of the baseline tax rate for ADS holders and any double tax treaty relief is available only if the tax treaty residence of the holder is provided to the custodian along with the other information prescribed by the Tax code. In relation to ADS holders such information is to be provided by the ADS holders to the depositary, who relays it to the custodian, who acts as the tax agent and withholds the taxes when making transferring the dividends to the depositary. It is currently unclear how the depositary will collect the necessary information from ADS holders. Thus, while a U.S. holder may technically be entitled to benefit from the provisions of the United States—Russia income tax treaty, in practice such relief may be difficult or impossible to obtain.

        Russian tax law and procedures are also not well developed, and local tax inspectors have considerable autonomy and often interpret tax rules without regard to the rule of law. Both the substantive provisions of Russian tax law and the interpretation and application of those provisions by the Russian tax authorities may be subject to more rapid and unpredictable change than in jurisdictions with more developed capital markets.

Taxation of Dividends

        Dividends paid to U.S. holders generally will be subject to Russian withholding tax at a 15% rate. The tax burden may be reduced to 5% or 10% under the United States—Russia income tax treaty for eligible U.S. holders; a 5% rate may potentially apply for U.S. holders who are legal entities owning 10% or more of the company's voting shares, and a 10% rate applies to dividends paid to eligible U.S. holders in other cases, including dividend payments to individuals and legal entities owning less than 10% of the company's voting shares. However, according to the recent amendments to the Tax Code, U.S. holders will only be able to utilize the 5% reduced rate through tax reimbursement procedures, as the tax agent is required to use the baseline tax rate established by the code or the applicable tax treaty, whichever is appropriate. See also "—United States—Russia Income Tax Treaty Procedures."

        Provisions of the Tax Code which were effective in 2015 have introduced 30% withholding tax rate to be applied to the dividends paid out in relation to shares underlying an ADS program where the information regarding the holders of the ADSs including the overall number of securities held in a specific tax jurisdiction is not provided by the depositary to the custodian holding the depo account with the underlying shares and acting as the tax agent.

        From a practical perspective, it may have not been possible for the depositary to collect the necessary information from all ADS holders and submit the relevant information to the custodian. Therefore, with respect to legal entities or organizations who are U.S. holders, the custodian may be obligated to withhold income tax at a rate of 30% from dividend payments made to the trustee, unless the information on the ADS holder, the respective amount of ADS held and its tax residency is provided to the depositary and thereafter to the custodian within 7 days of the date on which the shareholders entitled to dividend payout are determined according the relevant decision of the general shareholders meeting. The same amendments have also introduced an expedited refund process whereby the information regarding the ADSs not provided to the custodian can be submitted within 25 days of the date of the payment of the dividends to the depositary in order for the custodian to refund the difference between the increased 30% tax rate used and the tax rate the respective ADS holders are entitled to according to their tax residency, however this process is new and not tested and it is unclear how it will work in practice. Although non-resident holders of ADSs may apply for a refund of a portion of the tax withheld under an applicable tax treaty, the procedure to do so may be time consuming and no assurance can be given that the Russian tax authorities will grant a refund. See "—United States—Russia Income Tax Treaty Procedures."

        With respect to individuals who are U.S. holders of ADSs and who are Russian tax non-residents, the custodian may also be obligated to withhold income tax at the rate of 30% from dividend payments

made to the depositary. Where withholding of personal income tax is not performed, individuals who are U.S. holders of ADSs will then be required to submit an annual personal tax return to the Russian tax authorities and pay Russian income tax at a rate of 15% as under Russian law an individual should report on his or her tax liabilities in case the relevant tax was due but not withheld by a tax agent from the relevant payment. When submitting the tax return, individuals who are U.S. holders may claim an application of the reduced rates of withholding tax established by the relevant treaty, provided that the procedures described in "—United States—Russia Income Tax Treaty Procedures" are complied with. Obtaining the respective approvals from the tax authorities may be time-consuming and burdensome.

        If the appropriate information is not provided to the depositary for transfer to the custodian in a timely manner, the custodian may have to withhold tax at the 30% rate, and U.S. holders that are legal entities qualifying for a reduced rate under the United States—Russia income tax treaty then may file claims for a refund within three years with the Russian tax authorities.

        For individuals claiming treaty relief, the documents substantiating the right for treaty benefits should be submitted to the Russian tax authorities within one year after the end of the year to which these benefits relate. In practice, where withholding is performed, the tax authorities may refuse to refund or credit the 15% tax withheld from payment of dividends to the depositary and, therefore, it is possible that individuals who are U.S. holders may be subject to up to a 30% effective tax rate (general tax rate for Russian tax non-residents) on their share of dividends.

        The amendments to the Russian Tax Code, which came into effect from January 1, 2015, exclude dividends from the scope of payments subject to 30% withholding tax rate.

Taxation of Capital Gains

Legal entities and Organizations

        Income received by a foreign company from the sale, exchange or other disposal (assuming that such income is not related to a permanent establishment of a foreign company in Russia) of shares (participation interest) in an organization in which over 50% of the assets consist of immovable property located in Russia, as well as financial instruments derived from such shares, is treated as income derived from a source in the Russian Federation and is subject to withholding tax at a rate of 20%. However, gains arising from the disposition of the securities which are traded on an organized stock exchange are not treated as Russian-source income, and should not be subject to taxation in Russia.

        The amount of such income is typically determined as the sales price of shares (participation interest). However, if documentary support for the acquisition cost of the shares (participation interest) is available, the tax may instead be assessed on the basis of the difference between the sales price and the acquisition cost (including other related costs) if documentary evidence of such costs is submitted to the tax agent. The Russian Tax Code also establishes special rules for calculating the tax base for the purposes of transactions with securities. However, an exemption applies if immovable property located in Russia constitutes more than 50% of our assets and the securities are traded on a foreign stock exchange. The determination of whether more than 50% of our assets consist of immovable property located in Russia is inherently factual and is made on an on-going basis and the relevant Russian legislation and regulations in this respect are not entirely clear. Hence, there can be no assurance that immovable property owned by us and located in Russia does not currently and will not constitute more than 50% of our assets as at the date of the sale of ADSs by non-residents.

        Where the ADSs are sold by legal entities or organizations to persons other than a Russian company or a foreign company or an organization with a registered permanent establishment in Russia, even if the resulting capital gain is considered taxable in Russia, there is currently no mechanism under which the purchaser will be able to withhold the tax and remit it to the Russian budget.

216

Table of Contents

        Under the United States—Russia income tax treaty, capital gains from the sale of shares and/or ADSs by eligible U.S. holders should be relieved from taxation in Russia, unless 50% or more of our assets (the term "fixed assets" is used in the Russian version of the treaty) were to consist of immovable property located in Russia.

Individuals

        The taxation of the income of tax non-resident individuals depends on whether this income is received from Russian or non-Russian sources. Russian tax law considers the place of sale as an indicator of source. Accordingly, the sale of securities outside of Russia by individuals who are non-resident holders should not be considered Russian source income and, therefore, should not be taxable in Russia. However, Russian tax law gives no clear indication as to how the place of sale of securities should be defined in this respect. Therefore, the Russian tax authorities may have a certain amount of flexibility in concluding whether a transaction is in Russia or out of Russia.

        The sale, exchange or other disposal of the shares and ADSs by non-resident individual holders in Russia will be considered Russian source income and will be subject to tax at a rate of 30% on the difference between the sales price and the acquisition costs of such securities, as well as other documented expenses, such as depositary expenses and broker fees, among others, defined by the tax rules.

        Under Russian law, the acquisition costs and related expenses can be deducted at the source of payment if the sale was made by a non-resident holder through a licensed Russian broker, trust manager or other person that carries out operations under agency or commission agreements, or other agreements in favor of a taxpayer. Such party (as defined above) should also act as a tax agent and withhold the applicable tax. Such tax agent will be required to report to the Russian tax authorities the amount of income realized by the non-resident individual and tax withheld upon the sale of the securities.

        Otherwise, if the sale is made to individuals but not through a tax agent, generally no withholding needs to be made and the non-resident holder will have an obligation to file a tax return, report his income realized and apply for a deduction of acquisition expenses (which includes filing of support documentation). Although Russian tax law imposes tax agent responsibility only on professional trustees, brokers or dealers, in practice, the tax authorities may require Russian legal entities and organizations or foreign companies with any registered presence in Russia that are not professional trustees, dealers or brokers to act as tax agents and withhold the applicable tax when purchasing securities from non-resident individuals.

        Under the United States—Russia income tax treaty, capital gains from the sale of the ADSs by eligible U.S. holders should be relieved from taxation in Russia, unless 50% or more of our assets (the term "fixed assets" is used in the Russian version of the United States—Russia Tax Treaty) were to consist of immovable property located in Russia. If this 50% threshold is not met, individuals who are U.S. holders may seek to obtain the benefit of the United States—Russia income tax treaty in relation to capital gains resulting from the sale, exchange or other disposition of the ADSs.

        In order to apply the provisions of relevant double tax treaties, the individual holders should receive clearance from the Russian tax authorities as described below. See "—United States—Russia Income Tax Treaty Procedures" below.

United States—Russia Income Tax Treaty Procedures

        The Russian Tax Code does not contain a requirement that a non-resident holder that is a legal entity or organization must obtain tax treaty clearance from the Russian tax authorities prior to receiving any income in order to qualify for benefits under an applicable tax treaty. However, a

217

---

Table of Contents

non-resident legal entity or organization seeking to obtain relief from or reduction of Russian withholding tax under a tax treaty must provide to a Russian company or foreign company or organization acting through its Russian registered presence, which is a tax agent (i.e., the entity paying income to a non-resident) a confirmation of its tax treaty residence that complies with the applicable requirements and a Russian translation attached to it in advance of receiving the relevant income. The tax residency confirmation needs to be renewed on an annual basis and provided to the payer of income before the first payment of income in each calendar year.

        A U.S. holder may obtain the appropriate certification by mailing completed forms, together with the holder's name, taxpayer identification number, the tax period for which certification is required, and other applicable information, to the United States Internal Revenue Service. The procedures for obtaining certification are described in greater detail in the instructions to Internal Revenue Service Form 8802. As obtaining the required certification from the Internal Revenue Service may take at least six to eight weeks, U.S. holders should apply for such certification as soon as possible.

        In accordance with the Russian Tax Code, to rely on tax treaty benefits, a non-resident holder who is an individual must present to the tax authorities an official document confirming his residency in the home country issued by the competent authorities in his/her country of residence and also other supporting documentation including a statement confirming the income received and the tax paid in the home country, also confirmed by the relevant foreign tax authorities, duly translated and apostilled or pass through a consular legalization. Technically, such a requirement means that an individual cannot rely on the tax treaty until he or she pays the tax in the jurisdiction of his or her residence. Therefore, advance relief from or reduction of withholding taxes for individuals will generally be impossible as it is very unlikely that the supporting documentation for the treaty relief can be provided to the tax authorities and approval from the latter obtained before any payments are made to individuals. A non-resident holder which is an individual may apply for treaty-based benefits within one year following the end of the tax period in which the relevant income was received and the tax was withheld.

        If a non-resident holder which is a legal entity or organization does not obtain double tax treaty relief at the time that income or gains are realized and tax is withheld by a Russian tax agent, the non-resident holder may apply for a refund within three years from the end of the tax period (a calendar year) in which the tax was withheld. To process a claim for a refund, the Russian tax authorities require (i) apostilled or legalized confirmation of the tax treaty residence of the non-resident at the time the income was paid, (ii) an application for the refund of the tax withheld in a format provided by the Russian tax authorities and (iii) copies of the relevant contracts under which the foreign entity received income, as well as payment documents confirming the payment of the tax withheld to the Russian budget (Form 1012DT for dividends and interest and Form 1011DT for other income are designed by the Russian tax authorities to combine requirements (i) and (ii) specified above). The Russian tax authorities may require a Russian translation of the above documents if they are prepared in a foreign language. The refund of the tax withheld should be granted within one month of the filing of the above set of documents with the Russian tax authorities. However, procedures for processing such claims have not been clearly established and there is significant uncertainty regarding the availability and timing of such refunds.

        Recent amendments to the Tax Code have established additional requirements to the reimbursement procedure referred to above, identifying further documents that need to be provided to the tax authorities. These include: 1) a document confirming the rights of the ADS holder to the ADS as of the date on which the shareholders entitled to the dividend payout are set according to the relevant decision of the General shareholders meeting, 2) a document evidencing the actual amount of income received by the ADS holder, 3) a document with information about the custodian that transferred the dividend amounts to the depositary, and 4) documents confirming the ADS holder's compliance with the requirements of the Tax Code and/or the relevant income tax treaty provisions necessary for application of a reduced rate. The procedures referred to above are new and no

assurance can be given that the custodian will be able to apply the respective double tax treaties when paying dividends to non-resident holders or that ADS holders would be successful in receiving relevant tax refunds.

        Neither the depositary nor us has or will have any obligation to assist an ADS holder with the completion and filing of any tax forms.

Stamp Duties

        No Russian stamp duty will be payable by the holders of ADSs upon carrying out of transactions with the securities as discussed above (i.e., on a purchase of the securities, sale of the securities, etc.).

        The following is a general description of certain material United States federal income tax consequences that apply to you if you are, for United States federal income tax purposes, a beneficial owner of ADSs that is an individual who is a citizen or resident of the United States, a corporation created or organized in or under the laws of the United States, any state thereof or the District of Columbia, an estate the income of which is subject to U.S. federal income tax regardless of its source, or a trust, if a United States court can exercise primary supervision over the administration of the trust and one or more United States persons can control all substantial trust decisions, or if the trust has a valid election in effect under applicable U.S. Treasury Regulations to be treated as a United States person (in each case, a "U.S. Holder"). This discussion is based on the Internal Revenue Code of 1986, as amended (the "Code"), Treasury Regulations promulgated thereunder, judicial decisions, and published rulings and administrative pronouncements of the Internal Revenue Service ("IRS"), all as publicly available and in effect as of the date of this document. These authorities are subject to differing interpretations and may change, possibly retroactively, resulting in U.S. federal income tax consequences different from those discussed below. No ruling has been or will be sought from the IRS with respect to the matters discussed below, and there can be no assurance that the IRS will not take a contrary position regarding the tax consequences of the acquisition, ownership or disposition of ADSs, or that any such contrary position would not be sustained by a court. If an entity treated as a partnership for United States federal income tax purposes is an owner of ADSs, the United States federal income tax treatment of a partner in the partnership will generally depend on the status of the partner and the activities of the partnership. Accordingly, partnerships that hold ADSs and partners in such partnerships are urged to consult their tax advisors regarding the specific U.S. federal income tax consequences to them. The following discussion does not deal with the tax consequences to any particular investor or to persons in special tax situations such as:

•

an insurance company;



•

a tax-exempt organization;



•

a financial institution;



•

a person subject to the alternative minimum tax;



•

a person who is a broker-dealer in securities or a trader subject to a mark-to-market election;



•

an S corporation;



•

a person holding ADSs through a partnership or other pass-through entity;



•

an expatriate subject to section 877 of the Code;



•

an owner of, directly, indirectly or by attribution, 10% or more of the outstanding shares of our common stock; or

219

Table of Contents

•

an owner holding ADSs as part of a hedge, straddle, synthetic security or conversion transaction.

        In addition, this summary is limited to U.S. Holders holding ADSs as "capital assets" within the meaning of Section 1221 of the Code and whose functional currency is the U.S. dollar. The discussion below does not address the effect of the Medicare tax on "net investment income" or of any United States state or local tax law or foreign tax law. This discussion also does not address any tax consequences relating to the direct ownership of ordinary shares.

        The discussion below assumes that the representations contained in the deposit agreement are true and that the obligations in the deposit agreement and any related agreement will be complied with in accordance with their terms. For purposes of applying United States federal income tax law, we believe, and the following discussion assumes, that a holder of an ADS should be treated as the owner of the underlying shares of common stock represented by that ADS, although this matter is not free from doubt.

        The U.S. Treasury has expressed concerns that intermediaries in the chain of ownership between the holder of an ADS and the issuer of the shares underlying the ADS may be taking actions that are inconsistent with the beneficial ownership of the underlying shares. Accordingly, the analysis of the creditability of Russian withholding taxes described below and the availability of the reduced tax rate for dividends received by certain non-corporate U.S. Holders (discussed below) could be affected by actions taken by intermediaries in the chain of ownership between the holder of ADSs and our company if as a result of such actions the holders of ADSs are not properly treated as beneficial owners of underlying shares and future actions that may be taken by the U.S. Treasury. The remainder of this discussion assumes that a holder of an ADS will be treated as the beneficial owner of the underlying shares of common stock represented by such ADS for United States federal income tax purposes.

Taxation of Distributions on ADSs

        Subject to the passive foreign investment company rules described below, for United States federal income tax purposes, the gross amount of a distribution, including any Russian withholding taxes, paid by us with respect to ADSs will be treated as a taxable foreign source dividend on the date of actual or constructive receipt by the depositary to the extent of our current and accumulated earnings and profits, computed in accordance with United States federal income tax principles. If you are a non-corporate U.S. Holder such dividends may be "qualified dividend income" that is taxed at the lower applicable capital gains rate provided that certain conditions are satisfied, including (1) certain holding period requirements are satisfied, (2) either (a) our ADSs continue to be listed on the New York Stock Exchange (or other national securities exchange that is registered under section 6 of the Securities Exchange Act of 1934, as amended, or the Nasdaq Stock Market) or (b) we are eligible for the benefits of the United States—Russia income tax treaty, and (3) we are not, for the taxable year in which the dividend was paid, or in the preceding taxable year, a "passive foreign investment company" with respect to your ADSs (as discussed below). Distributions with respect to ADSs in excess of our current and accumulated earnings and profits will be applied against and will reduce your tax basis in such ADSs and, to the extent in excess of such tax basis, will be treated as gain from a sale or exchange of such ADSs. You should be aware that we do not intend to calculate our earnings and profits for United States federal income tax purposes and, unless we make such calculations, you should assume that any distributions with respect to ADSs generally will be treated as a dividend, even if such distributions would otherwise be treated as a return of capital or as capital gain pursuant to the rules described above. If you are a corporation, you will not be allowed a deduction for dividends received in respect of distributions on ADSs, which is generally available for dividends paid by U.S. corporations. U.S. Holders are strongly urged to consult their tax advisors as to the U.S. federal income tax treatment of any distribution received with respect to ADSs.

220

Table of Contents

        The amount of any distribution paid in rubles will equal the U.S. dollar value of such rubles, calculated using the exchange rate in effect on the date of actual or constructive receipt by the depositary, regardless of whether the payment is actually converted into U.S. dollars. Generally, any gain or loss resulting from currency exchange rate fluctuations during the period from the date of receipt by the depositary to the date the rubles are converted into U.S. dollars will be treated as ordinary income or loss from sources within the United States for foreign tax credit limitation purposes. Additionally, you may be required to recognize foreign currency gain or loss on the receipt of a refund of Russian withholding tax pursuant to the United States—Russia income tax treaty to the extent the United States dollar value of the refund differs from the dollar equivalent of that amount on the date of receipt of the underlying distribution.

        Russian withholding tax at the rate applicable to you under the United States—Russia income tax treaty should be treated as a foreign income tax that, subject to generally applicable limitations and conditions, may be eligible for credit against your U.S. federal income tax liability or, at your election, may be deducted in computing taxable income. If Russian tax is withheld at a rate in excess of the rate applicable to you under the United States—Russia income tax treaty, you may not be entitled to credits for the excess amount, even though the procedures for claiming refunds and the practical likelihood that refunds will be made available in a timely fashion are uncertain. If the dividends are qualified dividend income (as discussed above), the amount of the dividend taken into account for purposes of calculating the foreign tax credit limitation will generally be limited to the gross amount of the dividend, multiplied by the reduced rate divided by the highest rate of tax normally applicable to dividends.

        The limitation on foreign taxes eligible for credit is calculated separately with respect to specific classes of income. For United States foreign tax credit purposes, a dividend distribution with respect to the ADSs will be treated as foreign source "passive category income" but could, in the case of certain U.S. Holders, constitute "general category income." The rules relating to the determination of the foreign tax credit, or deduction in lieu of the foreign tax credit, are complex and you should consult your tax advisors with respect to those rules.

Taxation on Sale or Other Taxable Disposition of ADSs

        Subject to the passive foreign investment company rules described below, the sale or other taxable disposition of ADSs will generally result in the recognition of gain or loss in an amount equal to the difference between the amount realized on the sale or other taxable disposition and your adjusted basis in such ADSs. That gain or loss will be capital gain or loss and will be long-term capital gain or loss if you have held the ADSs for more than one year. If you are a non-corporate U.S. Holder, such recognized long-term capital gain is generally subject to a reduced rate of United States federal income tax. Limitations may apply to your ability to offset capital losses against ordinary income.

        Gain or loss recognized on the sale of ADSs will generally be treated as U.S. source income or loss for foreign tax credit purposes. The use of any foreign tax credits relating to any Russian taxes imposed upon such sale may be limited. You are strongly urged to consult your tax advisors as to the availability of tax credits for any Russian taxes withheld on the sale of ADSs.

Passive Foreign Investment Company Considerations

        A non-U.S. corporation generally will be a passive foreign investment company (a "PFIC"), in any taxable year in which, after taking into account the income and assets of the corporation and certain subsidiaries pursuant to applicable "look-through" rules, either (i) at least 75% of its gross income is "passive income" or (ii) at least 50% of the average value of its assets is attributable to assets which produce passive income or are held for the production of passive income.

221

---

Table of Contents

        We do not believe that we were a PFIC for the year ended December 31, 2015. However, our possible status as a PFIC must be determined annually and may be dependent in part on the market price of our ADSs, which may be volatile. Therefore, our possible status as a PFIC may be subject to change. Thus there can be no assurance that we will not be treated as a PFIC in our current taxable year or in the future. If we were to be treated as a PFIC, U.S. Holders generally would be required to pay additional taxes on certain distributions and gains on sales or other dispositions (including pledges) of the ADSs, at tax rates that may be higher than those otherwise applicable. You should consult your tax advisors regarding the application of the PFIC rules to your investment in the ADSs.

Information Reporting and Backup Withholding

        Dividend payments with respect to ADSs and proceeds from the sale or exchange of ADSs may be subject to information reporting to the IRS and possible U.S. backup withholding. Backup withholding will not apply, however, to a U.S. Holder who furnishes a correct taxpayer identification number and makes any other required certification or who is otherwise exempt from backup withholding. U.S. Holders who are required to establish their exempt status generally must provide such certification on IRS Form W-9. U.S. Holders should consult their tax advisors regarding the application of the U.S. information reporting and backup withholding rules.

        Backup withholding is not an additional tax. Amounts withheld as backup withholding may be credited against your U.S. federal income tax liability, and you may obtain a refund of any excess amounts withheld under the backup withholding rules by timely filing the appropriate claim for refund with the IRS and furnishing any required information.

Additional Reporting Requirements

        Certain U.S. Holders who are individuals may be required to report information relating to an interest in the ADSs, subject to certain exceptions (including an exception for ADSs held in accounts maintained by certain financial institutions). U.S. Holders should consult their tax advisors regarding the effect, if any, of this requirement on their ownership and disposition of the ADSs.

FATCA

        Provisions under Sections 1471 through 1474 of the Code and applicable U.S. Treasury Regulations commonly referred to as "FATCA" generally impose 30% withholding on certain "withholdable payments" and, in the future, may impose such withholding on "foreign passthru payments" made by a "foreign financial institution" (each as defined in the Code) that has entered into an agreement with the IRS to perform certain diligence and reporting obligations with respect to the foreign financial institution's U.S.-owned accounts. Prospective investors should consult their tax advisors regarding the potential impact of FATCA and any non-U.S. legislation implementing FATCA on the investment in ADSs.

Item 11.    Quantitative and Qualitative Disclosures about Market Risk

        We are exposed to market risk from changes in interest rates and foreign currency exchange rates. We are subject to market risk deriving from changes in interest rates, which may affect the cost of our financing. Foreign exchange risks exist to the extent our revenues, costs and debt obligations are denominated in currencies other than the functional currency in the countries of our operations.

Interest Rate Risk

        We are exposed to variability in cash flow risk related to our variable interest rate debt and exposed to fair value risk related to our fixed-rate notes. As of December 31, 2015, RUB 124,843 million, or 37.13% of our total indebtedness, excluding capital leases, was variable interest rate debt, while RUB 211,372 million, or 62.87% of our total indebtedness, excluding capital leases, was fixed interest rate debt.

        The table below presents principal cash flows and related weighted average interest rates for indebtedness by contractual maturity dates as of December 31, 2015.

Contractual Maturity Date as of December 31, 2015:

        We would have experienced an additional interest expense of approximately RUB 993 million on an annual basis as a result of a hypothetical increase in variable rates by 1% over the current rate as of December 31, 2015. The rates of EUR and USD as of December 31, 2015 were used in calculations.

Table of Contents

        The fair value of our publicly traded fixed-rate notes as of December 31, 2015, ranged from 89.05% to 108.25% of the notional amount. As of December 31, 2015, the difference between the carrying value and the fair value of other fixed rate debt, including capital lease obligations, was immaterial. For details of our fixed-rate debt, refer to Note 16 of our audited consolidated financial statements. The fair value of variable rate debt approximates its carrying value.

        We use derivative financial instruments to reduce our exposure to adverse fluctuations in interest rates. We primarily focus on reducing risk caused by the fluctuations in interest rates for our variable-rate long-term debt. According to our policy, we have entered into various variable-to-fixed interest rate swap agreements. The table below presents a summary of our variable-to-fixed interest rate swap agreements.

        As of December 31, 2015, approximately 32.6% of our variable interest rate debt was hedged against interest rate risks. We continue to consider other financial instruments available to us to mitigate exposure to interest rate fluctuations.

        We have also entered into several cross-currency interest rate swap agreements. These contracts, which hedge the risk of both interest rate and currency fluctuations, assume periodical exchanges of both principal and interest payments from ruble-denominated amounts to U.S. dollar- and euro-denominated amounts, to be exchanged at specified rates. The rates were determined with reference to the market spot rates upon issuance. These contracts also include an interest rate swap of a fixed U.S. dollar- and euro-denominated interest rate to a fixed ruble-denominated interest rate. All of our cross-currency interest rate swaps agreements mature in 2019 and 2020.

        The following tables show, for the periods indicated, certain information regarding the exchange rate between the ruble and the U.S. dollar, based on data published by the CBR. These rates may differ from the actual rates used in preparation of our financial statements and other financial information provided herein.

Table of Contents

        The exchange rate between the ruble and the U.S. dollar quoted by the CBR for April 20, 2016 was 65.65 rubles per U.S. dollar.

        The following tables show, for the periods indicated, certain information regarding the exchange rate between the hryvnia and the U.S. dollar, based on data published by the National Bank of Ukraine. These rates may differ from the actual rates used in preparation of our financial statements and other financial information provided herein.

        The exchange rate between the hryvnia and the U.S. dollar quoted by the National Bank of Ukraine for April 20, 2016 was 25.44 hryvnias per U.S. dollar.

        We have exposure to fluctuations in the value of the U.S. dollar relative to the Russian ruble, Ukrainian hryvnia, Turkmen manat, Armenian dram, and Uzbek sum which are the functional currencies in our countries of operation. As a result, we may face translation losses, increased debt service payments and increased capital expenditures and operating costs should these currencies depreciate against the U.S. dollar.

227

Table of Contents

        A significant part of our capital expenditures, borrowings and certain operating costs (roaming expenses, cost of customer equipment and other costs) are either denominated in U.S. dollars or tightly linked to the U.S. dollar exchange rate, and our U.S. dollar-denominated debt represents our primary future risk of exchange loss in U.S. dollar terms. A decline in the value of the ruble, hryvnia, manat, dram or sum versus the U.S. dollar would result in currency remeasurement losses as the amount of these currencies required to repay U.S. dollar-denominated debt increases. In addition, if any of the ruble, hryvnia, manat or dram declines against the U.S. dollar and tariffs cannot be maintained for competitive or other reasons, our revenues and operating margins could be materially adversely affected and we could have difficulty repaying or refinancing our U.S. dollar-denominated indebtedness and financing our capital expenditures and operating costs.

        A portion of our capital expenditures, borrowings and certain operating costs (roaming expenses, costs of customer equipment and other costs) are also denominated in euros. We currently do not hedge against the risk of decline in the ruble, hryvnia, manat, dram or sum against the euro because settlements denominated in euros are not significant.

        We would experience a currency exchange loss of RUB 8,986 million on our U.S. dollar-denominated net monetary liabilities as a result of a hypothetical 20.0% increase in the ruble/hryvnia/manat/dram/sum to U.S. dollar exchange rate at December 31, 2015. We would experience a currency exchange gain of RUB 5,664 million in the fair value of our euro-denominated net monetary liabilities as a result of a hypothetical 20.0% increase in the ruble/hryvnia/manat/dram to euro exchange rate at December 31, 2015. We are unable to estimate future loss of earnings as a result of such changes.

Item 15.    Controls and Procedures

(a)

Disclosure Controls and Procedures.

        As of the end of the period covered by this Annual Report on Form 20- F, we carried out an evaluation, under the supervision and with the participation of our management, including our CEO and CFO, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934).

        Based on this evaluation, our CEO and CFO concluded that our disclosure controls and procedures are effective, as of December 31, 2015, to provide reasonable assurance that the information required to be disclosed in filings and submissions under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified by the SEC's rules and forms, and that such information is accumulated and communicated to our management, including our CEO and CFO, as appropriate to allow timely decisions about required disclosure.

        There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives.

(b)

Management's annual report on internal control over financial reporting.

        Management is responsible for establishing and maintaining adequate internal control over financial reporting. Our internal control system was designed to provide reasonable assurance to our management and board of directors regarding the reliability of financial reporting and the preparation of financial statements for external purposes in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board.

        Internal control over financial reporting refers to a process designed by, or under the supervision of, our Chief Executive Officer and Chief Financial Officer and effected by our board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board and includes those policies and procedures that:

•

Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of our assets:



•

Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board, and that our receipts and expenditures are being made only in accordance with authorizations of our management and members of our board of directors;

231

Table of Contents

•

Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of our assets that could have a material effect on our financial statements.

        Management evaluated the effectiveness of our internal control over financial reporting as of December 31, 2015 based on the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission, or COSO, in Internal Control—Integrated Framework (2013).

        As a result of management's evaluation of our internal control over financial reporting, management concludes that internal control over financial reporting as of December 31, 2015 was effective.

        The effectiveness of our internal control over financial reporting as of December 31, 2015, has been audited and assessed as effective by independent registered public accounting firm ZAO Deloitte & Touche CIS who has also audited and reported on our consolidated financial statements.

        There were no changes in our internal control over financial reporting during the year ended December 31, 2015 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Attestation Report of Independent Registered Public Accounting Firm.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

        To the Board of Directors and Shareholders of Mobile TeleSystems PJSC:

        We have audited the internal control over financial reporting of Mobile TeleSystems PJSC and subsidiaries (the "Group") as of December 31, 2015, based on criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Group's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Group's internal control over financial reporting based on our audit.

        We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

        A company's internal control over financial reporting is a process designed by, or under the supervision of, the company's principal executive and principal financial officers, or persons performing similar functions, and effected by the company's board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with International Financial Reporting

232

Table of Contents

Standards as issued by the International Accounting Standards Board, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

        Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

        In our opinion, the Group maintained, in all material respects, effective internal control over financial reporting as of December 31, 2015, based on the criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

        We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements as of and for the year ended December 31, 2015 of the Group and our report dated March 21, 2016 expressed an unqualified opinion on those financial statements.

Changes in internal control over financial reporting.

        Management has evaluated, with the participation of our CEO and CFO, whether any changes in our internal control over financial reporting that occurred during the period covered by this annual report have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. Based on the evaluation we conducted, management has concluded that no such changes have occurred.

Item 16G.    Corporate Governance

        We are a company organized under the laws of the Russian Federation and qualify as a foreign private issuer as such term is defined in Rule 3b-4 of the Exchange Act. In accordance with the NYSE corporate governance rules, listed companies that are foreign private issuers are permitted in some circumstances to follow home country practice in lieu of the provisions of the corporate governance rules contained in Section 303A of the NYSE Listed Company Manual that are applicable to U.S. companies. In addition, foreign private issuers listed on the NYSE must disclose any significant ways in which their corporate governance practices differ from those followed by U.S. companies listed on the NYSE. With regard to our corporate governance practices, these differences can be summarized as follows:

•

For U.S. companies, the NYSE standards require that a majority of directors be independent, as determined by the board. Russian law does not require that a majority of our directors be independent. Of our nine directors, four have been determined by the board to be independent in accordance with the independence standards set forth in SEC Rule 10A-3 and Section 303A.02 of the NYSE Listed Company Manual.



•

For U.S. companies, the NYSE standards require that the audit committee have a minimum of three members. Russian law does not contain such a requirement. Our audit committee comprises of three members.



•

For U.S. companies, the NYSE standards require that non-management directors meet at regularly scheduled executive sessions without management. Russian law does not contain such a requirement. However, our audit committee and remuneration and nomination committee comprises of independent directors, who meet on a regular basis in connection with their work on these committees.



•

For U.S. companies, the NYSE standards require that listed companies have a nominating/corporate governance committee and a compensation committee, each composed entirely of independent directors and having a written charter specifying the committee's purpose and responsibilities, as well as annual performance evaluations of the committee.

Table of Contents

        We have a corporate governance committee comprising of directors and members of management that is responsible for developing and implementing standards for corporate governance and making recommendations to the Board of Directors on developing our strategy in the area of corporate governance. This committee is also responsible for conducting annual performance evaluations of the Board of Directors.

        We have a remuneration and nomination committee comprising of three independent directors. This committee functions pursuant to bylaws approved by the Board of Directors specifying the committee's purpose, duties and responsibilities. The committee is primarily responsible for recommending appointments to key managerial posts, developing a set of requirements and criteria for directors and management executives and developing a remuneration structure and compensation levels for the Board of Directors, the audit committee and management executives (including the CEO).

•

For U.S. companies, the NYSE standards require that shareholders be given the opportunity to vote on all equity compensation plans and material revisions. Under Russian law, such approval from shareholders is not required, and our equity compensation plans and material revisions thereto are currently approved by the Board of Directors.



•

For U.S. companies, the NYSE standards require the adoption and disclosure of corporate governance guidelines addressing certain subjects. Our corporate governance guidelines are consistent with what is required under Russian law and are set forth in our Charter, in the bylaw on our Board of Directors and in the bylaws of our various committees.

        In accordance with the corporate governance rules of the NYSE applicable to foreign private issuers, we also disclose these differences between our corporate governance practices and those required by the NYSE of listed U.S. companies on our Internet website at www.mtsgsm.com.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of Mobile TeleSystems PJSC:

        We have audited the accompanying consolidated statement of financial position of Mobile TeleSystems PJSC and subsidiaries ("the Group") as of December 31, 2015 and 2014 and January 1, 2014, and the related consolidated statements of profit or loss, comprehensive income, changes in shareholders' equity, and cash flows for each of the two years in the period ended December 31, 2015. These consolidated financial statements are the responsibility of the Group's management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

        We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

        In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of Mobile TeleSystems PJSC and subsidiaries as of December 31, 2015 and 2014 and January 1, 2014, and as the results of their operations and their cash flows for each of the two years in the period ended December 31, 2015 in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board.

        We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Group's internal control over financial reporting as of December 31, 2015 based on the criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated March 21, 2016 expressed an unqualified opinion on the Group's internal control over financial reporting.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

(Amounts in millions of Russian Rubles unless otherwise stated)

1. GENERAL INFORMATION AND DESCRIPTION OF BUSINESS

        Public Joint-Stock Company Mobile TeleSystems ("MTS PJSC", or "the Company") is a company incorporated under the laws of the Russian Federation and having its registered address at 4, Marksistskaya Street, 109147, Moscow, Russian Federation.

        The consolidated financial statements of the Company and its subsidiaries ("the Group" or MTS) as of 31 December 2015, 2014 and January 1, 2014, and for the years ended 31 December 2015 and 2014 were authorized for issue by the General Director on March 21, 2016.

        Business of the Group—MTS PJSC was incorporated on March 1, 2000, through the merger of MTS CJSC and Rosico TC CJSC, its wholly-owned subsidiary. MTS CJSC started its operations in the Moscow license area in 1994 and then began expanding through Russia and the CIS. MTS PJSC's majority shareholder is Joint-Stock Financial Corporation Sistema or "Sistema", whose controlling shareholder is Vladimir P. Yevtushenkov.

        The Group provides a wide range of telecommunications services including voice and data transmission, internet access, pay TV, various value added services through wireless and fixed lines, as well as selling equipment and accessories. The Group's principal operations are located in Russia, Ukraine, Turkmenistan, Uzbekistan and Armenia.

        MTS completed its initial public offering in 2000 and listed its shares of common stock, represented by American Depositary Shares, or ADSs, on the New York Stock Exchange under the symbol "MBT". Since 2003 common shares of MTS PJSC have been traded on the Public Joint-Stock Company "Moscow Exchange MICEX-RTS" ("Moscow Exchange").

        Since 2009, the Group has been developing its own retail network, operated by Russian Telephone Company CJSC ("RTC"), a wholly owned subsidiary of MTS PJSC.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND NEW ACCOUNTING PRONOUNCEMENTS

        Basis of preparation—The Group has previously prepared its consolidated financial statements in accordance with accounting principles generally accepted in the United States of America ("US GAAP"). Its last issued consolidated financial statements prepared in accordance with US GAAP are those as of December 31, 2014 and for the year then ended.

        These consolidated financial statements were prepared in accordance with International Financial Reporting Standards ("IFRS") as issued by the International Accounting Standards Board ("IASB"), as of December 31, 2015 and for the year than ended.

        These financial statements are the Group's first consolidated financial statements prepared in accordance with IFRSs, and accordingly IFRS 1, First-time Adoption of International Financial Reporting Standards, has been applied.

        An explanation of how the transition to IFRS has affected the reported financial position, financial performance and cash flows of the Group is provided in Note 4. The Note 4 includes reconciliations of equity and comprehensive income for comparative periods and at the date of transition reported under US GAAP to those reported for those periods and at the date of transition under IFRS.

(Amounts in millions of Russian Rubles unless otherwise stated)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND NEW ACCOUNTING PRONOUNCEMENTS (Continued)

        These consolidated financial statements are prepared on a historical cost basis, unless disclosed otherwise. Historical cost is generally based on the fair value of the consideration given in exchange for goods and services.

        Amounts in the consolidated financial statements are stated in millions of Russian Rubles, unless indicated otherwise.

        Basis of consolidation—The consolidated financial statements incorporate the financial statements of the Company and entities controlled by the Company. Control is achieved only where the Company has the power over the entity, is exposed and has rights to variable returns, and is able to use power to affect its amount of variable returns. The results of the controlled entities acquired or disposed of during the reporting period are included in the consolidated financial statements from the date, the Group achieves control over the entity, or until the date on which the Company ceases to control the entity. If necessary, the accounting policies of controlled entities' are aligned with the accounting policy applied by the Group. All intra-group balances, income, expenses and cash flows are eliminated on consolidation.

        Those entities where the Group exercises significant influence are recognized as associates and accounted for using the equity method. Significant influence is the power to participate in the financial and operating policy decisions of the investee but is not control or joint control over those policies. These entities are recognized at cost at the time of acquisition and adjusted thereafter to recognize the Group's share of the profit or loss and other comprehensive income. The carrying amount of the investment in such entities may include goodwill as the positive difference between the cost of the investment and Group's proportionate share in the fair values of the entity's identifiable assets and liabilities. The carrying amount of the investment accounted for using the equity method is tested for impairment provided there are indications of impairment. If the carrying amount of the investment exceeds its recoverable amount, an impairment loss is recognized in the amount of the difference. The recoverable amount is measured at the higher of fair value less costs of disposal and value in use. The Group presents its share in profits or losses in associates within operating profit if those interests are viewed as part of Group's core operations. As of December 31, 2015, only MTS Belarus was considered to be a part of Group's core operating activity. Shares in profits and losses of other Group's associates were presented as non-operating items.

        The Group has joint operations with MTS Bank, a Group associate, relating to the development of the MTS Dengi project and Vimpelcom, relating to construction of LTE base stations. Joint operations are characterized by the fact that the operators that have joint control over the arrangement have a right to the assets, and obligations for the liabilities, relating to the arrangement. Respectively, each operator accounts for its share of the joint assets and its agreed share of any liabilities, and recognizes its share of the output, revenues and expenses incurred under the arrangement.

        Investments in shares of the companies over which the Group does not have control or an ability to exercise significant influence are accounted for under the cost method. The Group does not evaluate cost-method investments for impairment unless there is an indicator of impairment.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND NEW ACCOUNTING PRONOUNCEMENTS (Continued)

        Acquisitions from entities under common control—Business combinations arising from transfers of interests in entities that are under common control with the Group are consolidated prospectively starting from the date, the control over those entities is passed to the Group. The assets and liabilities acquired are recognized at the carrying values recoded previously in the counterparty's financial statements with the resulting gain or loss recognized directly in equity.

        Functional currency translation methodology—As of December 31, 2015, the functional currencies of Group entities were as follows:

•

For entities incorporated in the Russian Federation, MTS Bermuda, Dega and MTS International—the Russian Ruble ("RUB");



•

For MTS Ukraine—the Ukrainian Hryvna;



•

For MTS Turkmenistan—the Turkmenian Manat;



•

For K-Telecom—the Armenian Dram;



•

For Universal Mobile Systems ("UMS")—the Uzbek Sum;



•

For MTS Belarus—the Belorussian Ruble.

        Foreign-currency transactions are translated into the functional currency at the exchange rates at the dates of the transactions. At the reporting date, monetary items denominated in foreign currencies are translated at the closing rate, whereas non-monetary items are stated at the exchange rate at the date of their recognition. Exchange rate differences are recognized in profit or loss.

        For entities whose records are maintained in their functional currency, which is other than the reporting currency, all year-end assets and liabilities have been translated into U.S. Dollars at the period-end exchange rate set by local central banks. Subsequently, U.S. Dollars balances have been translated into Russian Rubles at the period-end exchange rate set by the Central Bank of Russia. Revenues and expenses have been translated at the average exchange rate for the period using cross-currency exchange rate via U.S. Dollar as described above. Translation differences resulting from the use of these rates are reported as a component of other comprehensive income.

        Management estimates—The preparation of the consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

        Significant estimates include allowance for doubtful accounts and inventory obsolescence, the valuation of assets acquired and liabilities assumed in business combinations, the recoverability of

investments and the valuation of goodwill, property, plant and equipment and intangible assets, liability under put option agreement, certain provisions and financial instruments.

        Property, plant and equipment—Property, plant and equipment, including improvements, are stated at cost. Property, plant and equipment with a useful life of more than one year is capitalized at historical cost and depreciated on a straight-line basis over its expected useful life, as follows:

        The estimated useful lives and depreciation method are reviewed at the end of each reporting period, with the effect of any changes in estimate accounted for on a prospective basis.

        The gain or loss arising on the disposal of an item of property, plant and equipment is determined as the difference between any sale proceeds and the carrying amount of the asset and is recognised in the consolidated statement of profit or loss.

        Construction in progress and equipment held for installation is not depreciated until the constructed or installed asset is ready for its intended use. Maintenance and repair costs are expensed as incurred, while upgrades and improvements are capitalized.

        Borrowing costs—Borrowing costs directly attributable to the acquisition, construction or production of a qualifying asset during the construction phase that necessarily takes a substantial period of time are capitalized as part of property, plant and equipment until the asset is substantially ready for its intended use. The Group considers a construction period of more than six months to be substantial.

        Other intangible assets—Other intangible assets primarily consist of billing, telecommunication, accounting and office software as well as numbering capacity, customer base and licenses. These assets are assets with finite useful lives. They are initially recognized at cost and amortized on a straight-line basis over their estimated useful lives.

        Goodwill—Goodwill represents an excess of consideration transferred plus the fair value of any non- controlling interest in the acquiree at the acquisition date over the fair values of the identifiable net assets of the acquired entity. Goodwill is not amortized, but is tested for impairment based on the recoverable amount of the cash-generating unit to which the goodwill is allocated. The impairment test is carried out on a regular basis at the end of each financial year, as well as whenever there are

(Amounts in millions of Russian Rubles unless otherwise stated)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND NEW ACCOUNTING PRONOUNCEMENTS (Continued)

indications that the carrying amount of the cash-generating unit is impaired. For the purpose of impairment testing, goodwill acquired in a business combination is allocated to each of the cash- generating units that are expected to benefit from the synergies of the combination. If the carrying amount of the cash-generating unit to which goodwill is allocated exceeds its recoverable amount, goodwill allocated to this cash-generating unit must be reduced. Impairment losses for goodwill must not be reversed. If the impairment loss recognized for the cash-generating unit exceeds the carrying amount of the allocated goodwill, the additional amount of the impairment loss is recognized through the pro-rata reduction of the carrying amounts of the assets allocated to the cash-generating unit.

        Impairments of intangible assets and property, plant and equipment—Impairments are identified by comparing the carrying amount with the recoverable amount. If no future cash flows generated independently of other assets can be allocated to individual assets, recoverability is assessed on the basis of the cash-generating unit to which the assets can be allocated. At each reporting date, the Group assesses whether there is any indication that an asset may be impaired. If any such indication exists, the recoverable amount of the asset or cash-generating unit must be determined. In addition, at the end of each period the Group assesses whether there is any indication that an impairment loss recognized in prior periods for an asset other than goodwill no longer exists or may be decreased. If the impairment loss is reversed, the carrying amount of the asset (or a cash-generating unit) is increased to the revised estimate of its recoverable amount, but so that the increased carrying amount does not exceed the carrying amount that would have been determined had no impairment loss been recognized for the asset (or cash-generating unit) in prior years.

        Assets and disposal groups held for sale—The Group classifies assets and disposal groups as held for sale if their carrying amount will be recovered principally through a sale transaction rather than through continuing use. This condition is met only when the assets (or disposal group) are available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such assets (or disposal groups) and their sale is highly probable to occur within a year. Held for sale assets and disposal groups are measured at the lower of carrying amount or fair value less cost to sell.

        Inventories and spare parts—Inventories are stated at the lower of cost or net realizable value. Inventory cost is determined using the weighted average cost method. Handsets and accessories held for sale are expensed when sold. The Group regularly assesses its inventories for obsolete and slow- moving stock.

        Value-added tax ("VAT")—Value-added tax related to sales is payable to the tax authorities on an accrual basis based upon invoices issued to the customer. VAT incurred for purchases may be reclaimed from the state, subject to certain restrictions, against VAT related to sales.

        Income taxes—Income taxes of the Group's Russia-incorporated entities have been computed in accordance with Russian legislation and are based on the taxable profit for the period. The corporate income tax rate in Russia is 20%. The withholding tax rate on dividends paid within Russia is 13%. The foreign subsidiaries of the Group are paying withholding taxes in their respective jurisdictions. Deferred tax assets and liabilities are recognized for temporary differences between the carrying amounts of assets and liabilities in the consolidated financial statements and the corresponding tax bases of assets

and liabilities that will result in future taxable or deductible amounts. The deferred tax assets and liabilities are measured using the enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income.

        Financial instruments—A financial instrument is any contract that gives rise to a financial asset of one entity and a financial liability or equity instrument of another entity. Financial assets include, in particular, cash and cash equivalents, trade and other receivables, investments (mainly deposits with original maturity of more than three months, originated loans and notes) and derivative financial assets. Financial liabilities generally substantiate claims for repayment in cash or another financial asset. In particular, this includes bonds, trade and other payables, bank loans, finance lease obligations and derivative financial liabilities. Financial instruments are recognized as soon as the Group becomes a party to the contractual regulations of the financial instrument.

        Financial assets and financial liabilities are recognized initially at fair value plus transaction costs that are directly attributable to the acquisition or issue of the financial asset or financial liability, except for a financial asset or liability accounted for at fair value through profit or loss, in which case transaction costs are expensed. Subsequently they are measured either at amortized cost or fair value depending on classification of those assets and liabilities based on their purpose. Financial assets can be classified as 1) financial assets at fair value through profit or loss; 2) held-to-maturity investments; 3) available for sale financial assets; 4) loans and receivables. Financial liabilities can be classified as 1) financial liabilities at fair value or 2) other financial liabilities.

        Cash and cash equivalents—Cash and cash equivalents represent cash on hand and in bank accounts, as well as short-term bank deposits, which have original maturities of less than three months. Such investments are measured at amortized cost.

        Trade and other receivables—Trade and other receivables and are stated at their nominal value as reduced by appropriate allowance for doubtful accounts.

        Allowance for doubtful accounts—The Group provides an allowance for doubtful accounts based on management's periodic review with respect to the recoverability of trade receivables, advances given, loans and other receivables. Such allowance reflects specific cases, collection trends or estimates based on evidence of collectability.

        Short-term investments—Short-term investments mainly represent investments in loans, time deposits, which have original maturities in excess of three months and are repayable in less than twelve months, as well as investments in a mutual investment fund and debt securities. The investment in the mutual investment fund and debt securities were classified as available for sale and carried at fair value with unrealized gains and losses recorded as part of other comprehensive income. Deposits and loans are carried at amortized cost.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND NEW ACCOUNTING PRONOUNCEMENTS (Continued)

        Other investments—Other investments consist primarily of long-term deposits, which are repayable in more than a year, loans, notes and equity holdings in private companies. Deposits, loans and notes not quoted in active market are classified as loans and receivables and carried at amortized cost. The notes quoted in active market are classified based on Group's intention and ability to hold these notes to maturity either as held to maturity or available for sale. The Group reviews these investments for indicators of impairment on a regular basis.

        Trade payables and other non-derivative financial liabilities are measured at amortized cost.

        Hedging activities—The Group uses derivative instruments, including interest rate and foreign currency swaps, to manage foreign currency and interest rate risk exposures. The Group measures derivatives at fair value and recognizes them as either other current or other non-current financials assets or liabilities in the consolidated statement of financial position. Cash flows from derivatives are classified according to their nature. The Group reviews related fair value hierarchy classifications on a quarterly basis. The fair value measurement of the Group's derivative instruments is based on the observable yield curves for similar instruments.

        The Group designates derivatives as either fair value hedges or cash flow hedges in case the required criteria are met.

        Fair value hedges—Changes in the fair value of derivatives that are designated and qualify as fair value hedges are recognized in profit or loss immediately together with any changes in the fair value of the hedged asset or liability that is attributed to the hedged risk.

        Cash flow hedges—The effective portion of changes in the fair value of derivatives that are designated and qualify as cash flow hedges are recognized in other comprehensive income.

        The gain or loss relating to the ineffective portion is recognized immediately in profit or loss. Gains or losses accumulated in other comprehensive income are immediately reclassified into consolidated statement of profit or loss when related hedged transactions affects earnings.

        For derivatives that do not meet the conditions for hedge accounting, gains and losses from changes in the fair value are recorded immediately in profit or loss.

        Assets and liabilities related to multiple derivative contracts with one counterparty are not offset by the Group.

        Fair value of financial instruments—Fair value of financial assets and liabilities is defined as an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. The three-tier hierarchy for inputs used in measuring fair value, which prioritizes the inputs used in the methodologies of measuring fair value for assets and liabilities, is as follows:

•

Level 1—Quoted prices in active markets for identical assets or liabilities;



•

Level 2—Observable inputs other than quoted prices in active markets for identical assets and liabilities;

•

Level 3—No observable pricing inputs in the market.

        Financial assets and financial liabilities are classified in three-tier hierarchy based on the lowest level of input that is significant to the fair value measurements. The Group's assessment of the significance of a particular input to the fair value measurements requires judgment, and may affect the valuation of the assets and liabilities being measured and their placement within the fair value hierarchy.

        Liability under put option agreement—To optimize the structure of business acquisitions and to defer payment of the purchase price, the Group enters into put and call option agreements to acquire the remaining noncontrolling stakes in newly acquired subsidiaries. Upon initial recognition, the commitment to purchase non-controlling interests is recognized as a financial liability for the present value of the redemption amount, which approximates its fair value. Subsequent changes in the value of the commitment are recognized in profit or loss for the reporting period.

        Finance leases—Leases are classified as finance whenever the terms of the lease transfer substantially all risks and rewards incidental to ownership of the leased asset to the Group. At the commencement of the lease term, the leased asset is measured at the lower of fair value or present value of the future minimum lease payments and is depreciated over the lease term. The corresponding liability is recognized in the statement of financial position within borrowings. The discount rate used in the calculating the present value of minimum lease payments is the interest rate implicit in the lease. If there is no interest rate in the lease, the Group's incremental borrowing rate is used.

        Share-based payment programs—Equity-settled share-based payment transactions are measured at fair value on the grant date. The fair value of the obligation is recognized as personnel costs over the vesting period and offset against capital reserves. For cash-settled share-based payment transactions, the fair value of the obligation is newly determined at each reporting date and at the settlement date, and the changes in the fair value are recognized in profit or loss, until the liability is settled.

        Retirement benefits—MGTS, a subsidiary of the Group, has historically offered its employees certain benefits upon and after retirement, which form a defined benefit plan. The cost of providing benefits is determined using projected unit credit method with actuarial valuation being carried out at the end of each reporting period.

        Provisions—Provisions are recognized when the Group has a present obligation (legal or constructive) as a result of past event, it is probable that the Group will be required to settle that obligation and a reliable estimate can be made of the amount of the obligation. Provisions are measured at the managements' best estimate of the expenditure required to settle the obligation at the reporting date and are discounted to present value where the effect is material. The main provisions the Group holds are in relation of employees' bonus and other rewards, decommissioning and restoration obligation, tax provisions as well as legal claims.

        Provision for decommissioning and restoration—The Group calculates provision for decommissioning and restoration when the Group has a legal or constructive obligation in connection with the retirement of tangible long-lived assets. The Group's obligations relate primarily to the cost of removing its

equipment from sites. The Group recorded the present value of provision for decommissioning and restoration as non-current provisions in the consolidated statement of financial position.

        Subscriber prepayments—The Group requires the majority of its customers to pay in advance for telecommunications services. All amounts received in advance of services provided are recorded as a subscriber prepayment liability and are not recognized as revenues until the related services have been provided to the subscriber.

        Treasury stock—Shares of common stock repurchased by the Group are recorded at cost as treasury stock and reduce the shareholders' equity in the Group's consolidated financial statements.

        Revenue recognition—Revenue includes all revenues from the ordinary business activities of the Group. Revenues are measured at the fair value of the consideration received or receivable and recorded net of value-added tax. The Group recognizes revenue when the amount of revenue and related costs can be measured reliably; when it is probable that future economic benefit will flow to the Group; and when specific criteria have been met, as described below.

        Revenues derived from wireless, local telephone, long distance, data and video services are recognized when services are provided. This is based upon either usage (minutes of traffic processed, volume of data transmitted) or period of time (monthly subscription fees).

        Content revenue is presented net of related costs when the Group acts as an agent of the content providers while gross revenue and related costs are recorded when the Group acts as a primary obligor in the arrangement.

        Upfront fees received for connection of new subscribers, installation and activation of wireless, wireline and data transmission services ("connection fees") are deferred and recognized over the estimated average subscriber life, as follows:

        The Group calculates an average life of mobile subscribers for each region in which it operates and amortizes connection fees based on the average life specific to that region.

        Customer incentives—Incentives provided to customers are usually offered on signing a new contract or as part of a promotional offering. Incentives, representing the reduction of the selling price of the service (free minutes and discounts) are recorded in the period to which they relate, when the respective revenue is recognized, as a reduction to both trade receivables and service revenue.

        The Group regularly provides special incentives to its retail customers. Generally the Group sells mobile devices of worldwide known brands with an offer of free telecommunication services for a time period from one to twelve months. Such arrangements with a customer provide for two deliverables—a mobile device delivered immediately and mobile services to be consumed in the future. The consideration received from a customer is allocated between the deliverables based on their standalone

value on the market. Revenue on the devices sales is recognized at the moment of their sale, and the revenue on provision of free telecommunication services is deferred and recognized upon consumption by a subscriber.

        Prepaid cards—The Group sells prepaid cards to subscribers separately from the handset. Prepaid cards, used as a method of cash collection, are accounted for as subscriber prepayments. These cards allow subscribers to make a predetermined allotment of wireless phone calls and / or take advantage of other services offered by the Group, such as short messages and value-added services. Revenue from the sale of prepaid cards is deferred until the service is rendered to the customer, whereby the customer uses the airtime or the card expires.

        Roaming discounts—The Group enters into roaming discount agreements with a number of wireless operators. According to the terms of the agreements the Group is obliged to provide and entitled to receive a discount that is generally dependent on the volume of inter operator roaming traffic. The Group uses various estimates and assumptions, based on historical data and adjusted for known changes, to determine the amount of discount to be received or granted. Such estimates are adjusted monthly to reflect newly-available information.

        The Group accounts for discounts received as a reduction of roaming expenses and rebates granted as reduction of roaming revenue. The Group considers terms of the various roaming discount agreements in order to determine the appropriate presentation of the amounts receivable from and payable to its roaming partners in its consolidated statement of financial position.

        Sales and marketing expenses—Sales and marketing expenses consist primarily of dealers' commissions and advertising costs. Dealers' commissions are linked to revenues received during the six-month period from the date a new subscriber is activated by a dealer. The Group expenses these costs as incurred.

Standards, interpretations and amendments in issue but not yet effective

        The Group has not applied the following new and revised IFRSs that have been issued but not yet effective:

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND NEW ACCOUNTING PRONOUNCEMENTS (Continued)

        IFRS 9, Financial Instruments.    IFRS 9 governs the classification and measurement of financial assets and liabilities, derecognition, impairment and hedge accounting matters. The Group is currently evaluating the impact of these amendments on the Group's consolidated financial statements.

        IFRS 15, Revenue from Contracts with Customers.    This standard provides a single, principles-based five-step model for the determination and recognition of revenue to be applied to all contracts with customers. It replaces the existing standards IAS 18, Revenue, and IAS 11, Construction Contracts. The core principle of IFRS 15 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Under the standard, an entity recognizes revenue when (or as) a performance obligation is satisfied, i. e. when "control" of the goods or services underlying the particular performance obligation is transferred to the customer. Far more prescriptive guidance has been added in IFRS 15 to deal with specific scenarios. Furthermore, extensive disclosures are required by IFRS 15. The Group is currently evaluating the impact of these amendments and the transition alternatives on the consolidated financial statements.

        IFRS 16, Leases.    This standard principally requires lessees to recognize assets and liabilities for all leases and to present the rights and obligations associated with these leases in the statement of financial position. Going forward, lessees will therefore no longer required to make the distinction between finance and operating leases. For all leases, the lessee will recognize a lease liability in its statement of financial position for the obligation to make future lease payments. At the same time, the lessee will capitalize a right of use to the underlying asset which is generally equivalent to the present value of the future lease payment plus directly attributable expenditures. The standard also includes new provisions on the definition of a lease and its presentation, on disclosures in the notes, and on sale and leaseback transactions. The Group is currently evaluating the impact of these amendments on the consolidated financial statements.

        Other mentioned IFRS pronouncements do not have a material impact on the Group's consolidated financial statements.

3. SIGNIFICANT ACCOUNTING JUDGMENTS, ESTIMATES AND ASSUMPTIONS

Critical accounting estimates

        A critical accounting estimate is an estimate that is both important to the presentation of the Group's financial position and requires management's most difficult, subjective or complex judgments, often as a result of the need to determine estimates and develop assumptions about the outcome of matters that are inherently uncertain.

        Management evaluates such estimates on an on-going basis, based upon historical results, historical experience, trends, consultations with experts, forecasts of the future, and other methods which

3. SIGNIFICANT ACCOUNTING JUDGMENTS, ESTIMATES AND ASSUMPTIONS (Continued)

management considers reasonable under the circumstances. Management considers the accounting estimates discussed below to be its critical accounting estimates, and, accordingly, provides an explanation of each.

Depreciation and amortization of non-current assets

        Depreciation and amortization expenses are based on management estimates of useful life, residual value and amortization method of property and equipment and intangible assets. Estimates may change due to technological developments, competition, changes in market conditions and other factors and may result in changes in the estimated useful life and in the amortization or depreciation charges. Technological developments are difficult to predict and our views on the trends and pace of development may change over time. Some of the assets and technologies, in which the Group invested several years ago, are still in use and provide the basis for the new technologies. Critical estimates in the evaluations of useful lives for intangible assets include, but are not limited to, the estimated average customer relationship based on churn, the remaining license period and the expected developments in technology and markets.

        The useful lives of property and equipment and intangible assets are reviewed at least annually, taking into consideration the factors mentioned above and all other important relevant factors. The actual economic lives of intangible assets may be different from our estimated useful lives, thereby resulting in a different carrying value of our intangible assets with finite lives.

        The Group continues to evaluate the amortization period for intangible assets with finite lives to determine whether events or circumstances warrant revised amortization periods. A change in estimated useful lives is a change in accounting estimate, and depreciation and amortization charges are adjusted prospectively. See Notes 12 and 15 for further information.

Impairment of non-current assets

        The Group has made significant investments in property and equipment, intangible assets, goodwill and other investments.

        Pursuant to IAS 36, goodwill and other intangible assets with indefinite useful lives and intangible assets not yet brought into use must be tested for impairment annually or more often if indicators of impairment exist. Other assets are tested for impairment when circumstances indicate that there may be a potential impairment.

        Estimating recoverable amounts of assets and CGUs must, in part, be based on management's evaluations, including the determination of the appropriate CGUs, the discount rate, estimates of future performance, the revenue generating capacity of the assets, timing and amount of future purchases of property and equipment, assumptions of the future market conditions and the long-term growth rate into perpetuity (terminal value). Changing the assumptions selected by management, in particular, the discount rate and growth rate assumptions used to estimate the recoverable amounts of assets, could significantly impact the Group's impairment evaluation and hence results.

3. SIGNIFICANT ACCOUNTING JUDGMENTS, ESTIMATES AND ASSUMPTIONS (Continued)

        All of the Group's operations is in countries with emerging markets. The political and economic situation in these countries may change rapidly and recession may potentially have a significant impact on these countries. On-going recessionary effects in the world economy, and increased macroeconomic risks, impact our assessment of cash flow forecasts and the discount rates applied.

        There are significant variations between different markets with respect to growth, mobile penetration, Average Revenue Per User ("ARPU"), market share and similar parameters, resulting in differences in operating margins. The future developments of operating margins are important in the Group's impairment assessments, and the long-term estimates of these margins are highly uncertain.

        See Notes 13 and 14 for further information about the goodwill and impairment test.

Fair value of financial instruments

        Where the fair value of financial assets and financial liabilities recorded in the statement of financial position cannot be derived from active markets, their fair value is determined using valuation techniques, including discounted cash flow models. The inputs to these models are taken from observable markets where possible, but when this is not feasible, a degree of judgment is required in establishing fair values. The judgments include considerations of inputs such as liquidity risk, credit risk and volatility. Changes in assumptions about these factors could affect the reported fair value of financial instruments. See Note 18 for further information.

Provisions and contingencies

        The Group is subject to various legal proceedings, disputes and claims, including regulatory discussions related to the Group's business, licenses, tax positions and investments, where the outcomes are subject to significant uncertainty. In addition, significant uncertainty exists in relation of employee bonuses and other rewards, which depend on their individual performance and Group's results. Management evaluates, among other factors, the degree of probability of an unfavorable outcome and the ability to make a reasonable estimate of the amount of loss or related expense. Unanticipated events or changes in these factors may require the Group to increase or decrease the amount recorded or to be recorded for a matter that has not been previously recorded because it was not considered probable.

        See Note 17 and Note 29 for further information.

4. IFRS FIRST-TIME ADOPTION

        The date of transition to IFRS is January 1, 2014. For periods up to and including the year ended December 31, 2014, the Group prepared its consolidated financial statements in accordance with US GAAP.

        The accounting principles described in Note 2 were applied when preparing the consolidated financial statements as of December 31, 2015 and for the year then ended, comparative information and the opening statement of financial position as of the date of transition to IFRS. An explanation of how the transition from US GAAP to IFRS has affected the Group's financial position, financial performance and cash flows is set further in this note.

4. IFRS FIRST-TIME ADOPTION (Continued)

        As a first-time adopter of IFRS, the Group applied IFRS 1, First-Time Adoption of International Financial Reporting Standards. The Standard contains a number of voluntary and mandatory exemptions from the requirement to retrospectively apply IFRS effective at December 31, 2015.

        The Group has applied the mandatory exceptions and certain optional exemptions as set out below:

        Business combinations—The Group has not applied IFRS 3, Business Combinations, retrospectively to business combinations occurred before the date of transition to IFRS. As a result, assets recognized and liabilities assumed in past business combinations under US GAAP have remained unchanged at the date of transition.

        Provision for decommissioning and restoration—The Group has elected to use the IFRS 1 exemption relating to recognition of historical changes in the measurement of decommissioning liabilities and therefore measures those in accordance with IFRIC 1, Changes in Existing Decommissioning, Restoration and Similar Liabilities, as of January 1, 2014.

        Borrowing costs—The Group has applied the transitional provisions in IAS 23, Borrowing costs, and capitalizes borrowing costs on qualifying assets as of the date of transition, and where the construction was commenced as of and after the date of transition to IFRS. Borrowing costs capitalized under US GAAP prior to the date of transition have not been adjusted.

        Currency translation differences—The Group has used the IFRS 1 exemption relating to IAS 21, The Effects of changes in foreign currency rates. As a result, the cumulative translation differences for all foreign operations of the Group were set to be zero at the date of transition. The gain or loss on a subsequent disposal of any foreign operation will include only translation differences that arose after the date of transition.

        Estimates—The estimates as of the transition date are consistent with those made under US GAAP.

        Changes in the presentation—The Group changed the presentation of certain items in the consolidated statements of financial position, profit or loss and comprehensive income as compared to the presentation used under US GAAP. The most significant changes in the presentation related to:

•

Interest receivable and payable are presented as part of trade and other receivables or payables instead of being part of other current assets and accrued liabilities;



•

VAT payable is included in other current non-financial liabilities instead of being a part of accrued liabilities;



•

Income tax assets are presented as a separate items instead of being part of prepaid expenses, other non-current assets, respectively;



•

Derivative assets and liabilities are presented as part of other financial assets and liabilities instead of being a part of other current or non-current assets and other long-term liabilities;



•

The liability related to the put option over non-controlling interests is included in other non- current / current financial liabilities instead of being a separate line item; under US GAAP the

Provisions for decommissioning and restoration is included in provisions instead of being part of other long-term liabilities;



•

Tax provisions other than income tax are excluded from accrued liabilities and presented within current provisions;

•

Retirement and post-retirement obligations are included in non-current provisions instead of being a separate line item;



•

Current deferred connection fees as well as taxes other than VAT and income tax are presented as other current non-financial liabilities, instead of being a separate line item or a part of accrued liabilities;



•

Non-current deferred connection fees as well as property, plant and equipment contributions are presented within other non-current non-financial liabilities instead of being separate line items;



•

Prepayments related to taxes other than income and custom services are included in advances paid and prepaid expenses instead of being part of other current assets;



•

Licenses are included in other intangible assets instead of being a separate line item;

•

Other operating expense/income are reduced to reflect only items relating to disposal of property, plant and equipment or intangible assets, impairments (including bad debt allowance and inventory obsolescence reserve), any write offs or gains resulting from annual stock taking, compensation of losses.



•

Changes in current income tax assets and liabilities, interest receivable and payable are presented gross in the statement of cash flows. Accordingly, related expenses or income as well as cash payments and receipts are presented in separate line items. For US GAAP purposes, these changes were presented net in changes in operating assets and liabilities lines; and



•

Changes in provisions, recognized in the statement of profit or loss for the reporting period, are stated as a separate line item of statement of cash flows instead of being included in the change of trade payables, accrued and other liabilities.

A—Loans to Associates

        Under IFRS, loans to associates are treated as other investments instead of investments in associates.

B—Deferred Taxes

        Deferred tax assets and liabilities are treated only as non-current under IFRS. Netting is performed for deferred tax assets and liabilities relating to income taxes levied by the same taxation authority on the same taxable entity where the Group has a legally enforceable right to set off current tax assets against current tax liabilities.

C—Debt issuance costs

        In accordance to IFRS fees paid on the establishment of loan facilities are recognized as transaction costs which are presented as a reduction of the related liability. Under US GAAP debt issuance costs were capitalized as an asset and included in other non-financial assets.

4. IFRS FIRST-TIME ADOPTION (Continued)

D—Currency translation differences

        Please refer to exemption on currency translation differences described above.

E—Revenue for multiple element arrangements

        Under US GAAP, revenue recognition is based on fixed or determinable pricing criteria, which results in contingent amounts generally not being recorded as revenue until the contingency is resolved. IFRS looks to probability of economic benefits associated with the transaction flowing to the entity and the ability to reliably measure the revenue in question, including any contingent revenue. This results in different treatment of revenue generated from sales of a bundle of mobile devices with an offer of free telecommunication services. In accordance with US GAAP, the provision of service revenue was seen as contingent so that major part of revenue from the bundle was allocated to services and deferred until rendering. IFRS requires allocation of the consideration for bundles to goods and services proportionately based on fair value.

F—Decommissioning and restoration costs

        Decommissioning and restoration costs are treated as finance costs instead of cost of services.

G—Share of the profit of loss of associates

        Share of the profit of MTS Belarus is treated as item of operating profit instead of being included in non-operating items.

Adjustments:

H—Reversal of Turkmenistan impairment

        Under US GAAP reversal of impairments is prohibited. While under IFRS if certain criteria are met, the reversal of impairments, other than those of goodwill, is permitted. MTS recognized impairment losses for goodwill and long-lived assets in Turkmenistan due to suspension of its operations in 2010. As a result of negotiations with the Government of Turkmenistan, MTS resumed its operations in Turkmenistan in July 2012. Impairment losses of Turkmenistan assets other than those of goodwill were reversed at the date of transition.

I—Change in functional currency

        Effective from 1 January 2007, the Company's functional currency was changed from the US dollar to the Russian Ruble. Under US GAAP, the change in the functional currency to the Ruble was accomplished by restating the carrying amount of certain non-monetary balances (mainly property, plant and equipment) as if the Ruble had been the functional currency when these assets were acquired. Under IFRS, such a change of functional currency would have been performed by translating all balances using the foreign exchange rate at the date of the change in functional currency.

4. IFRS FIRST-TIME ADOPTION (Continued)

J—Provision for decommissioning and restoration

        According to US GAAP, provision for decommissioning and restoration was measured based on the estimated cost of decommissioning, discounted to its net present value upon recognition. However, adjustments to the discount rate are not reflected in the provisions under US GAAP unless there was an upward revision in the future cost estimates. The Group has taken the exemption for which IFRIC 1, Changes in Existing Decommissioning, Restoration and Similar Liabilities, applies and has revalued the provision for decommissioning and restoration as of 1 January 2014 using current discount rate at the date. In the subsequent periods, the provision for decommissioning and restoration is remeasured using the current discount rate as of the end of each reporting period.

K—Capitalization of interest

        According to IFRS, borrowing costs are capitalized for qualifying assets that require a substantial period of time to get ready for its intended use or sale. US GAAP does not require such a period to be substantial. The Group defined that only assets that require more than six months to get ready for their intended use or sale are qualifying assets and remeasured the value of related capitalized interest for the reporting periods after the date of transition.

L—Retirement obligation in MGTS

        IFRS requires prior service cost arising from changes to employees' benefit plans to be recognized immediately in profit or loss whereas US GAAP assumes to initially recognize service cost in accumulated other comprehensive income and then amortize into profit or loss over the plan participants' remaining service periods or life expectancy. Under IFRS all actuarial gains and losses are recognized immediately in accumulated other comprehensive income and should not be recycled to profit or loss in future periods, US GAAP requires cumulative balance to be amortized through the income statement after the initial recognition under the corridor amortization approach. IFRS unlike US GAAP requires to recognize the liability including social taxes. Accordingly, the Group retrospectively recalculated retirement obligation in MGTS.

M—Hyperinflation accounting

        IFRS requires the financial statements of an entity whose functional currency is the currency of a hyperinflationary economy are restated by applying a general price index and translated at closing rates. US GAAP requires that the financial statements of a foreign entity in a highly inflationary economy are remeasured as if the functional currency were the reporting currency. The Group restated the results of its associate—MTS Belarus—which operated in hyperinflationary economy till December 31, 2014, in accordance with requirements of IFRS and adjusted its share in profit of the associate, respectively.

N—Loyalty programs

        The Group accounted for award credits granted to the subscribers participating in the loyalty programs by accruing the estimated costs of providing free or discounted goods or services to those subscribers that are expected to redeem accumulated award credits (commonly referred to as the "incremental cost" model in US GAAP). The incremental cost model is not permitted under IFRS. In

accordance with IFRS, the Group estimates the fair value of the awards to the customers and defers this amount of revenue until the unused award credits are redeemed or expired. The amount of deferred revenue is measured by reference to the fair value of the award credits to the customer.

5. BUSINESS ACQUISITIONS AND DISPOSALS

Acquisition and disposals in 2015

        Acquisition of Stream—In December 2015, the Group increased its share in Stream from 45% to 100%, after Sistema Mass Media, subsidiary of Sistema, exchanged ownership of 55% in Stream for rights for its own debt in amount of RUB 561 million and promissory notes of LLC Stream Digital (fully-owned subsidiary of Stream) of RUB 1,089 million due on demand and bearing interest of 9% p.a. Stream operates as content aggregator, providing VAS services mainly to the Group. The acquisition was accounted for as a transaction under common control directly in equity.

        Acquisition of Nvision Group—In the first stage of the transaction, carried in July 2015, the Group has acquired 100% of the shares of SITRONICS Telecom Solutions CJSC, NVision program solutions, NVision Czech Republic a.s. and some smaller subsidiaries of NVision Group, from subsidiaries of Sistema. Through this transaction, the Group has obtained proprietary rights over billing system, exploited by the Group, which will allow reducing time-to-market for new products and billing and IT-related expenses. In December 2015, the Group has completed acquisition of 100% share in the holding company NVision Group JSC ("NVision Group"), from subsidiaries of Sistema. NVision Group is also one of the largest system integrators and complex IT solutions providers in Russia. Total consideration amounted to RUB 11,213 million, including RUB 73 million in notes and RUB 11,140 million in cash. As of December 31, 2015 the Group has accounted for indemnification asset in amount of RUB 386 million related to tax provisions of acquired companies. The acquisition was accounted for as a transaction under common control directly in equity.

        Acquisition of Navigation Information Systems—In January 2015, the Group acquired 89.5% of Navigation Information Systems ("NIS") from Sistema for RUB 44 million. NIS is the leading systems integrator for GLONASS satellite projects. The acquisition allows the Group to develop its proprietary technological platform for machine-to-machine solutions. The acquisition was accounted for as a transaction under common control directly in equity.

        Disposal of Rent Nedvizhimost—In February 2015, the Group sold 51% stake in its wholly-owned subsidiary Rent Nedvizhimost to a subsidiary of Sistema, for RUB 4.3 billion. The Group classified the associated assets and liabilities of the disposal group as held for sale as of December 31, 2014. After the loss of control, the Group applied for its remaining 49% interest the equity method of accounting. Further, in May 2015, the Group sold remaining 49% interest to a subsidiary of Sistema for RUB 4.2 billion. These disposals were accounted for as transactions under common control directly in equity.

        Acquisition of Smarts companies—In December 2014 the Group acquired controlling stakes in Penza-GSM, SMARTS-Ivanovo and SMARTS-Ufa, operating in Penza, Ivanovo and the Bashkortostan Republic, respectively. The acquired companies hold rights to use 900 and 1800 MHz radio frequencies. The acquisition enhances the Group's spectrum resources in the above regions. The purchase price comprised of cash consideration and a deferred payment, payable in 18 months after the acquisition date. The acquisition was accounted for using the acquisition method.

        The purchase price allocation of SMARTS-Ivanovo, SMARTS-Ufa and Penza-GSM was not finalized as of the date the 2014 financial statements were authorised for issue as the Group had not completed the valuation of individual assets of each company acquired. The Group's consolidated financial statements as of 31 December, 2014 reflected the allocation of the purchase price based on a preliminary fair value assessment of the assets acquired and liabilities assumed.

5. BUSINESS ACQUISITIONS AND DISPOSALS (Continued)

        In 2015 the Group finalized valuation of assets of Smarts companies and the acquisition date fair value of the assets changed. The following table summarizes the purchase price allocation for Smarts companies:

        Under the terms of purchase agreements the Group is obliged to pay additional consideration of RUB 150 million in 18 months after the acquisition date. The consideration could be reduced by the amount of tax expenses related to activities prior to the acquisition date. As of December 31, 2015 the Group recorded a provision for tax liabilities in the amount of RUB 23 million and respectively reduced the additional consideration. Given the effects of discounting of long-term liability, total liability for additional consideration equaled RUB 115 million as of December 31, 2015.

        The excess of the consideration paid over the value of net assets acquired in the amount of RUB 1,621 million was allocated to goodwill which was attributable to the "Russia convergent" segment. Goodwill mainly arised from expected synergies on economies of scale related to operating and capital expenditures.

        Licenses acquired are amortized over a period of their remaining useful life of average 15 years. Customer base acquired is amortized over the period of its estimated average useful life of 51 months.

        Disposal of Business-Nedvizhimost—In December 2013, the Group sold a 51% stake in Business- Nedvizhimost CJSC to Sistema for RUB 3.2 billion. Business-Nedvizhimost owns and manages 76 real estate sites and 44 real estate facilities throughout Moscow with a total area of roughly 178,000 sq. m. After the loss of control over the subsidiary, the Group deconsolidated Business-Nedvizhimost and applied for its 49% interest the equity method of accounting. In April 2014, the Group sold the remaining 49% stake to Sistema for RUB 3.1 billion. The disposal was accounted for as a transaction under common control directly in equity.

13. GOODWILL

        The change in the net carrying amount of goodwill for the years ended December 31, 2015 and 2014 by operating segments was as follows:

14. IMPAIRMENT REVIEW

        Management of the Group performs impairment tests for the goodwill assigned to the cash- generating units at least annually and when there are any indications that the carrying amount of the cash-generating unit ("CGU") is impaired.

        When reviewing for indicators of impairment management of the Group considers, among other things, the relationship between its market capitalization and book value, changes in country risk premiums and other.

        When the carrying amount of the cash generating unit to which goodwill is allocated exceeds its recoverable amount, goodwill allocated to tis cash generating unit must be impaired.

        The recoverable amounts of the CGUs are determined based on their value in use. In assessing value in use, the estimated future cash flows are discounted to present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the CGU.

        Future cash flows calculations are based on five-year operation plan, which is prepared and approved by the management of the Group. Estimation of future cash flows requires assumptions to be made in respect of uncertain factors, including management's expectations of the following: OIBDA

margin, timing and amount of future capital expenditure, terminal growth rates and appropriate discount rates to reflect the risks involved.

        As a result of impairment test as of December 31, 2015 impairment charges of RUB 3.5 billion were recorded in a separate line item within operating profit in the consolidated statement of profit or loss in respect of the Group's investment in operating segment "Armenia". The impairment charges relate solely to goodwill. The impairment reflects the decrease of interconnect traffic and related revenue due to dramatic growth of prices for international calling from Russia to Armenia. The recoverable amount of CGU "Armenia" was RUB 18.5 billion as of 31 December 2015.

        During the year ended December, 31 2014 and as of January 1, 2014, no impairment charges were recorded in respect of the Group's goodwill balances.

Key assumptions used for value in use calculation:

        OIBDA margin and capital expenditures were primarily derived from internal sources, were based on past experience and extended to include management expectations.

        The table below presents OIBDA margin utilized for value in use calculation of related CGUs:

        The table below presents capital expenditure as a percentage of revenue utilized for value in use calculation of related CGUs:

        The terminal growth rate into perpetuity has been determined based on the nominal gross domestic product rates for the country of operation, adjusted for specific characteristic of the CGUs business.

14. IMPAIRMENT REVIEW (Continued)

        The table below presents terminal growth rate utilized for value in use calculation of related CGUs:

        The discount rate, applied to measure free cash flow, is the weighted average cost of capital, determined by the weighted average cost of equity and debt according to the finance structure established for each CGU. The cost of equity is calculated based on the risk free rate for long-term bonds issued by the government in the respective market. These rates adjusted for a risk premium to reflect both the increased risk of investing in equities and the systematic risk of the specific operating company of the Group. The cost of debt is defined as the rate effective for borrowings drawn by the Group at or near the date of impairment test.

        The table below presents pre-tax rates for discounting of cash flows in functional currencies of related CGUs:

Sensitivity analysis

        Management believes that no reasonably possible change in any of the above key assumptions would cause the carrying value of any cash-generating unit to materially exceed its recoverable amount, except for CGU Armenia.

        The carrying value of the CGU Armenia is equal to the estimated recoverable amount, any adverse change in key assumptions would, in isolation, cause a further impairment loss to be recognized.

        The changes in the following table to assumptions used in the impairment review of CGU Armenia would have, in isolation, lead to an increase to the impairment loss recognized in the year ended December 31, 2015:

        There were no transfers between the accounting categories of financial instruments during the year ended December 31, 2015 and 2014.

19. FINANCIAL RISK MANAGEMENT

        As part of its business the Group is exposed to several types of financial risks: market risks, credit (or counterparty) risks, and liquidity risks. Risks mitigating activities are mainly performed at the Group headquarters by the corporate finance personnel and are subject to the approval of the Group's supervisory bodies—Board of Directors and Budget committee.

Market risk

        Market risk is the risk that the fair value of future cash flows of a financial instrument will fluctuate because of changes in market prices. The Group is primarily exposed to the following types of market risks: interest rate risk and currency exchange rates fluctuations. Financial instruments affected by market risk include loans and borrowings, deposits, and derivative financial instruments. The sensitivity analyses in the following sections relate to the position as of December 31 2015, 2014 and January 1, 2014.

Interest rate risks

        Interest rate risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in market interest rates. The Group manages its interest rate risk by having a balanced portfolio of fixed and variable rate loans and borrowings.

•

Variable interest rate

        Group's bank loans denominated in US dollars and Euros primarily bear floating interest rate. To eliminate the exposure of changes in variable interest rates related to its debt obligations, the Group enters into variable-to-fixed interest rate swap agreements, so that interest rate swap matches the exact maturity dates of the underlying debt allowing for highly-effective cash flow hedges. In aggregate the Group entered into variable-to-fixed interest rate swap agreements designated to manage the exposure of changes in variable interest rates related to 32.6% and 84.2% of the Group's bank loans with variable rates outstanding as of December 31, 2015 and 2014, respectively.

•

Fixed interest rate risk

        Group's Notes and bank loans denominated in rubles bear primarily fixed interest rates. To eliminate the exposure of changes in value of debt obligations, the Group enters into fixed-to-variable

        The notionals related to interest rate derivative instruments amounted to RUB 67,338 million, RUB 65,561 million and RUB 31,757 million as of December 31, 2015, 2014 and January 1, 2014, respectively.

        A reasonably possible increase of 100 basis points in short term interest rates would have resulted in RUB 933 million and RUB 264 million increases of interest expense for the years ended December 31, 2015 and 2014, respectively. The same decrease in short term interest rates would have resulted in RUB 933 million and RUB 233 million decreases of finance cost for the years ended December 31, 2015 and 2014, respectively. There will be no material impact on equity.

        The interest rate sensitivity analysis was performed based on a constant position of fixed and floating rate debt.

Foreign currency risks

        Foreign currency risk is the risk that the fair value or future cash flows will fluctuate because of changes in foreign exchange rates. The Group's exposure to the risk of changes in foreign exchange rates relates primarily to the Group's financing activities. The Group manages its currency risk by hedging significant foreign currency cashoutflows with derivates and by using money market instruments.

        The Group has entered into several cross-currency swap agreements. The contracts designated to manage the exposure of changes in currency exchange rate. The contracts assumed periodic exchange of principal and interest payments from RUB-denominated amounts to USD- and Euro- denominated amounts at a specified rate. The rate was determined by the market spot rate upon issuance. Cross-currency interest rate swap contracts mature in 2019-2020.

        In aggregate the Group entered into cross-currency interest rate swap agreements designated to manage the exposure of changes in currency exchange rate for 28.7% of the Group's bank loans denominated in USD- and Euro- denominated bank loans outstanding as of December 31, 2015 and 35.1% of its USD- and Euro- denominated bank loans outstanding as of December 31,2014:

        The notionals related to currency derivative instruments amounted to RUB 40,049 million, RUB 37,820 million and RUB 26,020 million as of December 31, 2015, 2014 and January 1, 2014, respectively.

19. FINANCIAL RISK MANAGEMENT (Continued)

        The following tables demonstrate the sensitivity to a reasonably possible change in USD and EUR exchange rates, with all other variables held constant.

        The movement in the pre-tax effect is a result of a change in monetary assets and liabilities denominated in US dollars and Euro, where the functional currency of the entity is a currency other than US dollars and Euro.

        There will be no material impact on equity.

        The Group's exposure to foreign currency changes for all other currencies is not material.

Liquidity risk

        Liquidity risk is the risk of a shortage of funds. The Group's policy is to borrow centrally using a mixture of long-term and short-term borrowing facilities. These borrowings, together with cash generated from operations are utilized to meet anticipated funding requirements.

        The Group manages liquidity risk on long-term borrowings by maintaining a varied maturity profile and a required net debt position, therefore minimizing refinancing risk. Long-term borrowings mature between one and 8 years.

Credit risk

        Credit risk is the risk that a counterparty will not meet its obligations under a financial instrument, leading to a financial loss. The Group is exposed to credit risk primarily from its investing activities.

        The Group considers its exposure to credit risk as of December 31, 2015, December 31, 2014 and January 1, 2014 to be as follows:

        In accordance with the Group's financial instruments management policy, the aggregate credit risk the Group may have with one counterparty is limited. The Group maintains mixture of cash and cash equivalents, investments, derivatives and certain other financial instruments with financial

institutions.These financial institutions are located in different geographical regions and the Group's policy is designed to limit exposure to any one institutions. As part of its risk management processes, the Group performs periodic evaluations of the relative credit standing of the financial institutions. Moreover,at December 15, 2015 Barclays bank and the Group signed an addendum to cross currency swap agreements. According to the terms of the addendum parties agreed to set credit exposure limits to one another, which permits to mitigate their credit risk by requiring other party to transfer collateral payments. As of December 31, 2015 Barclay bank transferred to the group a collateral paymentin the amount of RUB 6,9 billion.

        Concentrations of credit risk with respect to trade receivables are limited given that the Group's customer base is large and unrelated. Therefore management believes there is no further credit risk provision required in excess of the normal provision for bad and doubtful receivables.

        Significant components of income tax expense for the year ended December 31, 2015 and 2014 was as follows:

Dividends

        As a leading telecommunications group with a home base in developing markets, MTS' primary need is to maintain sufficient resources and flexibility to meet financial and operational requirements.At the same time, the Group continually seeks ways to create shareholder value through both its commercial and financial strategies, including organic and inorganic development as well as the Group's capital management practices.

        MTS continue to include dividend payments as part of commitment to maximizing shareholder value. Decisions on dividends are proposed by the Board of Directors and voted upon thereafter at a general meeting of shareholders. In determining the Company's dividend payout, the Board of Directors considers a variety of factors, including:

•

Macroeconomic factors and levels of competitiveness in core markets,



•

Cash flow from operations,



•

The outlook for earnings growth,



•

Capital expenditure requirements,



•

Potential acquisition opportunities,



•

The state of capital markets and the Group's liquidity position, and



•

The Group's overall debt position.

        In 2013, the Board of Directors approved a dividend policy, whereby the Group shall aim to make minimum dividend distribution payments to shareholders for the calendar years 2013-2015 in the amount equal to at least 75% of Free cash flow for the relevant financial period or, if greater, RUB 40.0 billion per year. Free cash flow is defined by cash flows from operating activities less cash paid (received) for acquisition or disposal of property, plant and equipment, intangible assets and other adjustments.

        The Group may take decisions on dividend payout based not only on financial year-end results but also based on interim results for three, six or nine months of the fiscal year. Annual and interim dividend payments, if any, must be recommended by the Board of Directors and approved by the shareholders.

        In accordance with Russian laws, earnings available for dividends are limited to profits determined under Russian statutory accounting regulations, denominated in Russian Rubles, after certain deductions.

installment due in January 2013 totaling approximately RUB 481 million and constituting the remaining amount of cash held in its bank accounts, Uzdunrobita filed a petition for voluntary bankruptcy to the Tashkent Economic Court on the grounds of its inability to meet further obligations.

        Considering the adverse impact of such circumstances on the Group's ability to conduct operations in Uzbekistan, the Group tested goodwill and other long-lived assets attributable to Uzbekistan for impairment upon first receiving notification of the investigations. As a result, an impairment loss on the long-lived assets in the amount of RUB 20,037 million was recorded in the consolidated statements of profit or loss for the year ended December 31, 2012. In 2013 these losses were assigned to discontinued operations.

        On April 22, 2013, the Tashkent Economic Court declared Uzdunrobita bankrupt and initiated a liquidation process. Uzdunrobita was later liquidated. As a result the Group lost control over the subsidiary and deconsolidated Uzdunrobita.

        In 2012, the Group filed a claim against the Republic of Uzbekistan in the International Center for Settlement of Investment Disputes ("ICSID"), part of the World Bank Group, in Washington, D.C.

        On July 31, 2014, MTS and the Republic of Uzbekistan signed a settlement agreement (the "Settlement Agreement") which motivated MTS to reenter the Uzbekistan market. A joint enterprise, Universal Mobile Systems LLC ("UMS"), was established with MTS holding a 50.01% in the charter capital of the entity, while the remaining 49.99% belongs to a state-owned unitary enterprise established and managed by the State Committee for Communications, Development of Information Systems and Telecommunications Technologies of the Republic of Uzbekistan. The Settlement Agreement is governed by English law and provides for resolution of any disputes arising out of the Settlement Agreement in the International Court of Arbitration under International Chamber of Commerce in Paris (ICC).

        On November 2014, ICSID has discontinued international arbitration proceedings between MTS and the Republic of Uzbekistan following the submission of a joint application by both parties.

Universal Mobile Systems LLC ("UMS")

        On September 24, 2014, in accordance with the Settlement Agreement, the authorities of the Republic of Uzbekistan granted UMS 2G, 3G and LTE licenses, provided necessary frequencies and numbering capacity, fostered entrance into lease agreements for communication channels and issued all permissions required to UMS so it could operate and offer full telecommunications services throughout Uzbekistan. UMS has also received guaranties for investment protection and return of investments in accordance with the laws of the Republic of Uzbekistan. Independent appraisers hired by the Group determined the total fair value of UMS to be RUB 9,062 million as of the transfer date.

        Based on the aforementioned fair value assessment of a 50.01% stake in UMS, the Group recognized a gain from reentrance into Uzbekistan pursuant to the Settlement Agreement in the amount of RUB 6,734 million. Management concluded that this consideration related to, in its entirety, a financial incentive to encourage re-entry into the Republic of Uzbekistan and as such, recognition in continuing operations was appropriate. No element was allocated to the non-satisfaction and elimination of mutual claims as this was deemed to have minimal value.

27. OPERATIONS IN UZBEKISTAN (Continued)

        The allocation of consideration received between elements where the settlement of litigation is involved is highly judgmental. In this case, management considered, among other things the terms of the settlement arrangement as well as the development of the negotiations process itself, in which members of MTS management were involved.

        The Group consolidates UMS starting from September 24, 2014, representing the date of transfer of ownership. Below is the summary of fair value allocation regarding the incentive arrangement:

        The fair value of non-controlling interest as of the date of consolidation in the amount of RUB 3,573 million was determined based on a discounted cash flow technique utilizing significant unobservable inputs ("Level 3" in the hierarchy established by IFRS). The key assumptions in the fair value calculations included a discount rate of 24.1% and average price per minute of voice services amounting to RUB 0.56.

Risks

        The currency conversion process in Uzbekistan is subject to certain restrictions. Due to the lack of hard currency in the exchange market, entities which operate in Uzbekistan are able to convert limited amounts of cash through several authorized banks. Practically Bank conversion may take several months. As of December 31, 2015 and 2014, the cash balances in Uzbekistan amounted to RUB 623 million and RUB 346 million, respectively.

        In September 2007, the Group acquired an 80% stake in International Cell Holding Ltd, the 100% indirect owner of K-Telecom, Armenia's mobile phone operator, and signed a call and put option agreement to acquire the remaining 20% stake. In December 2010, the Group signed an amendment to the put and call option agreement. According to the amended option agreement, the price for the remaining 20% stake option will be determined by an independent investment bank subject to a cap of EUR 200 million. The put option can be exercised during the period from the next business day following the date of settlement of all liabilities under the loan agreement up to December 31, 2016. The call option can be exercised during the period from July 1, 2010 up to December 31, 2016. If both the call notice and the put notice are served on the same day then the put notice shall be deemed exercised in priority to the call notice. The liability under put option agreement amounted to RUB 2,925 million, RUB 3,192 million and RUB 2,932 million as of December 31, 2015, December 31, 2014 and January 1, 2014, respectively (Note 18).

29. COMMITMENTS AND CONTINGENCIES

        Capital commitments—As of December 31, 2015, the Group had executed purchase agreements of approximately RUB 27,615 million to acquire property, plant and equipment, intangible assets and costs related thereto.

        Operating leases—The Group has entered into non-cancellable agreements to lease space for telecommunications equipment, offices and transmission channels, which expire in various years up to 2064. Rental expenses under the operating leases of RUB 6,093 million and RUB 5,624 million for the year ended December 31, 2015 and 2014, respectively, are included in selling, general and administrative expenses in the accompanying consolidated statement of profit or loss.

consolidated statement of profit or loss. Future minimum lease payments due under these leases at December 31, 2015 are as follows:

        Taxation—Russia and other CIS countries currently have a number of laws related to various taxes imposed by both federal and regional governmental authorities. Applicable taxes include VAT, corporate income tax (profits tax), a number of turnover-based taxes, and payroll (social) taxes.

        Laws related to these taxes have not been in force for significant periods, in contrast to more developed market economies; therefore, the government's implementation of these regulations is often inconsistent or non-existent. Accordingly, few precedents with regard to tax rulings have been established. Tax declarations, together with other legal compliance areas (for example, customs and currency control matters), are subject to review and investigation by a number of authorities, which are enabled by law to impose extremely severe fines, penalties and interest charges. These facts create tax risks in Russia and the CIS countries that are more significant than those typically found in countries with more developed tax systems.

        Generally, according to Russian and Ukrainian tax legislation, tax declarations remain open and subject to inspection for a period of three years following the tax year. As of December 31, 2015, tax declarations of MTS PJSC and other subsidiaries in Russia and Ukraine for the preceding three fiscal years were open for further review.

        The Group purchases supplemental software from foreign suppliers of telecommunications equipment in the ordinary course of business, which is subject to customs regulation. In addition pricing of revenue and expenses between each of the Group's subsidiaries and various discounts and bonuses to the Group's subscribers in the course of performing its marketing activities may be subject to transfer pricing rules.

        Management believes that it has adequately provided for tax and customs liabilities in the accompanying consolidated financial statements. However, the risk remains that the relevant tax and customs authorities could take differing positions with regard to interpretive issues and the effect could be significant.

29. COMMITMENTS AND CONTINGENCIES (Continued)

        The Group accesses the following contingent liabilities in respect of additional tax and customs settlements:

        Licenses—In July 2012, the Federal Service for Supervision in the Area of Communications, Information Technologies and Mass Media allocated MTS the necessary license and frequencies to provide LTE telecommunication services in Russia. Under the terms and conditions of the LTE license, the Group is obligated to fully deploy LTE networks within seven years, commencing from January 1, 2013, and deliver LTE services in each population center with over 50,000 inhabitants in Russia by 2019. Also, the Group is obligated to invest at least RUB 15 billion annually toward the LTE roll-out until the network is fully deployed.

        In May 2007, the Federal Service for Supervision in the Area of Communications, Information Technologies and Mass Media awarded MTS a license to provide 3G services in Russia. The 3G license was granted subject to certain capital and other commitments.

        In March 2015, upon winning a tender, MTS-Ukraine has acquired a nationwide license for the provision of UMTS (3G) telecommunications services. The license with the cost of UAH 2,715 million (RUB 6,015 million at the acquisition date) has been granted for 15 years. In accordance with the terms of the license MTS-Ukraine is required to launch 3G services in Ukraine by October, 2015, and provide coverage across Ukraine by April, 2020.

        In accordance with the terms of the license, MTS-Ukraine also concluded agreements on conversion of provided frequencies with the Ministry of Defense of Ukraine, Ministry of Internal Affairs of Ukraine and State Service of Special Communications and Information Protection of Ukraine. As of December 31, 2015, MTS-Ukraine has paid UAH 358 million (RUB 865 million as of the payment date) for conversion of frequencies and is liable to pay UAH 267 million (RUB 705 million as of December 31, 2015) adjusted for the rate of inflation in the years 2017-2018.

        Management believes that as of December 31, 2015 the Group complied with conditions of aforementioned licenses.

        Litigation—In the ordinary course of business, the Group is a party to various legal, tax and customs proceedings, and subject to claims, certain of which relate to developing markets and evolving fiscal and regulatory environments in which MTS operates. Management believes that the Group's liability, if any, in all such pending litigation, other legal proceeding or other matters will not have a material effect upon its financial condition, results of operations or liquidity of the Group.

        Potential adverse effects of economic instability and sanctions in Russia—In 2014 political and economic sanctions were introduced by the EU, US and other countries targeting certain Russian economic sectors. There is significant uncertainty regarding the extent and timing of further sanctions.

Also, Russian Ruble has materially depreciated against the U.S. Dollar and Euro and ruble interest rates have increased significantly after the Central Bank of Russia raised its key rate to 17% in December, 2014. The decline of Russian Ruble continued in 2015. The Central Bank of Russia has decreased its key rate to 11% as of December 31, 2015. However, the key rate remains higher than in the beginning of the year 2014, when it was equal to 5.5%. Russia sovereign credit ratings also were decreased.

        These factors resulted in a higher cost of capital, increased inflation and uncertainty regarding further economic growth, which could have a negative impact on the Group's business including ability to obtain financing on commercially reasonable terms. Management believes it is taking the appropriate measures to support the sustainability of the Group's business in the current circumstances. The Group has a hedging policy in place, which partly mitigated variability of cash outflows, denominated in foreign currencies.

        Political and economic crisis in Ukraine—During the year ended December 31, 2014, a deterioration in the political environment of Ukraine has led to general instability, economic deterioration and armed conflict in eastern Ukraine. The deterioration has further exacerbated the country's already weak macroeconomic trends, which have led to reduced credit ratings, significant depreciation of its national currency and increased inflation. During 2014, the Ukrainian Parliament adopted a law allowing for the imposition of sanctions against countries, persons and companies deemed by the Ukrainian government to threaten Ukrainian national interests, national security, sovereignty or the territorial integrity of Ukraine. The National Bank of Ukraine ("NBU") passed a decree prohibiting Ukrainian companies to pay dividends to foreign investors. The decree was extended for a few times and currently acts till June 2016. These circumstances, combined with continued political and economic instability in the country, could result in further negative impact on the Group's business including our financial position and results of operations.

        Such risks especially apply to funds deposited in Ukrainian banks, whose liquidity is affected by the economic downturn. As of December 31, 2014, the Group held RUB 21,203 million in current accounts and deposits in Ukrainian banks, including RUB 5,072 million in Delta Bank. In December 2014, Delta Bank delayed customer payments and put limits on cash withdrawals. On March 2, 2015, NBU adopted a resolution declaring Delta Bank to be insolvent. The Group reserved the full amount of deposited funds (RUB 5,072 million) and related interest (RUB 66 million) as of December 31, 2014. During the year ended December 31, 2015, the Group created additional reserve of RUB 1,698 million for cash balances deposited in distressed Ukrainian banks (including RUB 185 million for cash balances deposited in Delta Bank, RUB 868 million for cash balances deposited in bank Kyivska Rus and RUB 645 million for cash balances deposited in Platinum Bank) that was included as a component of operating expenses in the accompanying consolidated statement of profit or loss.

        Also, in 2015 the Group entered in a factoring agreement in respect to cash balances deposited in bank Kyivska Rus, under which the factor is obliged to reimburse the Group for 45% of cash balance. As of December 31, 2015 the Group did not account for asset under this agreement, as no transfer of funds was made. As of December 31, 2015, the Group held RUB 6,612 million in current accounts and deposits in Ukrainian banks.

        Investigations into former operations in Uzbekistan—In March 2014, the Group received requests for the provision of information from the United States Securities and Exchange Commission ("SEC") and the United States Department of Justice ("DOJ") relating to a currently conducted investigation of the Group's former subsidiary in Uzbekistan.

        In July 2015, activities related to the Group's former operations in Uzbekistan have been referenced in a civil forfeiture complaint ("The Complaint"), filed by DOJ in the U.S. District Court, Southern District of New York (Manhattan), directed at certain assets of an unnamed Uzbek government official. The Complaint alleges among other things that MTS and certain other parties made corrupt payments to the unnamed Uzbek official to assist their entering and operating in the Uzbekistan telecommunications market. The Complaint is solely directed towards assets held by the unnamed Uzbek official, and none of MTS's assets are affected by the Complaint.

        The Company continues to cooperate with these investigations. The Company cannot predict the outcome of the investigations, including any fines or penalties that may be imposed, and such fines or penalties could be significant.

30. SUBSEQUENT EVENTS

        Liquidation of Mobile TeleSystems Finance S.A.—In February 2016, the Group's subsidiary Mobile TeleSystems Finance S.A. was liquidated. The discontinuance of Mobile TeleSystems Finance S.A. operations does not have a material effect on the Group's financial results.

        Acquisition of MTS Bank PJSC shares—On February 25, 2016 the Group acquired 946,347 ordinary shares of MTS Bank, placed as part of an earlier approved additional issue, for a total consideration of RUB 1,325 million. As the result of the transaction, the Group's share in the capital of MTS Bank decreased from 27.0% to 26.8%.
