AGL RESOURCES INC. AND SUBSIDIARIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
Note 1 - Organization and Basis of Presentation
General
AGL Resources Inc. is an energy services holding company that conducts substantially all of its operations through its subsidiaries. Unless the context requires otherwise, references to “we,” “us,” “our,” the “company,” or “AGL Resources” mean consolidated AGL Resources Inc. and its subsidiaries.
Our Condensed Consolidated Balance Sheet as of December 31, 2015 was derived from our audited consolidated financial statements. We have prepared the accompanying unaudited condensed consolidated financial statements under the rules and regulations of the SEC. In accordance with such rules and regulations, we have condensed or omitted certain information and notes that would typically be included in our annual audited financial statements. Our unaudited condensed consolidated financial statements reflect all adjustments of a normal recurring nature that are, in the opinion of management, necessary for a fair statement of our financial results for the interim periods and should be read in conjunction with our consolidated financial statements and related notes included in Item 8 of our 2015 Form 10-K.
Due to the seasonal nature of our business and other factors, our results of operations and our financial condition for the periods presented are not necessarily indicative of the results of operations or financial condition to be expected for, or as of, any other period.
Basis of Presentation
Our unaudited condensed consolidated financial statements include our accounts, the accounts of our wholly owned subsidiaries and the accounts of our VIE for which we are the primary beneficiary. For unconsolidated entities that we do not control, we use the equity method of accounting and our proportionate share of income or loss is recorded on our unaudited Condensed Consolidated Statements of Income. See Note 10 for additional information on our non-wholly owned entities. We have eliminated intercompany profits and transactions in consolidation except for intercompany profits where recovery of such amounts is probable under the affiliates’ rate regulation process.
Certain amounts from prior periods have been reclassified to conform to the current period presentation. These reclassifications had no material impact on our prior period balances.
Note 2 - Proposed Merger with Southern Company
On August 23, 2015, we entered into the Merger Agreement with Southern Company and a new wholly owned subsidiary of Southern Company (Merger Sub), providing for the merger of Merger Sub with and into AGL Resources, with us surviving as a wholly owned, direct subsidiary of Southern Company. At the effective time of the merger, which is expected to occur in the second half of 2016, each share of our common stock, other than certain excluded shares, will convert into the right to receive $66 in cash, without interest, less any applicable withholding taxes.
We and Southern Company have made joint filings seeking regulatory approval with all of the required state regulatory agencies. Completion of the merger remains subject to various closing conditions, including (i) the receipt of remaining required regulatory approvals from the Illinois Commission and New Jersey BPU, and such approvals having become final orders and (ii) the absence of a judgment, order, decision, injunction, ruling or other finding or agency requirement of a governmental entity prohibiting the closing of the merger.
To date, the proposed merger has been approved by the Maryland Commission, the Georgia Commission, the California Public Utilities Commission, the Virginia Commission and our shareholders. Additionally, we received consent from the Federal Communications Commission to transfer parent company control of radio licenses held by certain of our subsidiaries and the waiting period under the Hart-Scott-Rodino Act has expired.
On April 28, 2016, Southern Company, AGL Resources, Nicor Gas, the Illinois Attorney General’s Office, and the CUB filed a settlement agreement with the Illinois Commission that resolves all remaining contested issues with regards to the merger approval. This settlement agreement, along with the other resolved matters, is still subject to approval by the Illinois Commission.
The Merger Agreement contains certain termination rights for each party. In addition, the Merger Agreement, in certain circumstances, provides for the payment by AGL Resources of a $201 million termination fee to Southern Company and, in certain circumstances, provides for the reimbursement of expenses up to $5 million upon termination of the erger Agreement (which reimbursement would reduce on a dollar-for-dollar basis any termination fee subsequently paid by us). As of March 31, 2016, we had recorded no liability for termination fees.
During the three months ended March 31, 2016, we recorded $3 million ($2 million, net of tax) of merger-related costs on the accompanying unaudited Condensed Consolidated Statements of Income, which consisted primarily of legal expenses and additional share-based compensation expenses associated with the proposed merger. These costs are treated as tax deductible since the requisite closing conditions to the merger have not yet been satisfied. Once the merger is closed, we will evaluate the tax deductibility of all merger-related costs and adjust for any non-deductible amounts in the effective tax rate.

Note 3 - Significant Accounting Policies and Methods of Application
Our significant accounting policies are described in Note 3 to our consolidated financial statements and related notes included in Item 8 of our 2015 Form 10-K. There have been no significant changes to our accounting policies during the three months ended March 31, 2016.
Use of Accounting Estimates
The preparation of our financial statements in conformity with GAAP requires us to use judgment and make estimates that affect the reported amounts of assets, liabilities, revenues and expenses and the related disclosures. Our estimates are based on historical experience and various other assumptions that we believe to be reasonable under the circumstances. Our estimates may involve complex situations requiring a high degree of judgment either in the application and interpretation of existing accounting literature or in the development of estimates that impact our financial statements. The most significant estimates relate to the accounting for our rate-regulated subsidiaries, goodwill and other intangible assets, derivatives and hedging activities, uncollectible accounts and other allowances for contingent losses, retirement plan benefit obligations and provisions for income taxes. We evaluate our estimates on an ongoing basis, and our actual results could differ from our estimates.
Inventories
For our regulated utilities, except Nicor Gas, natural gas inventories and the inventories we hold for Marketers in Georgia are carried at cost on a WACOG basis.
Nicor Gas’ inventory is carried at cost on a LIFO basis. Under the LIFO method, inventory decrements occurring during the year that are expected to be restored prior to year-end are charged to cost of goods sold at the estimated annual replacement cost, and the difference between this cost and the actual liquidated LIFO layer cost is recorded as a temporary LIFO liquidation on our unaudited Condensed Consolidated Balance Sheets. Interim inventory decrements that are not expected to be restored prior to year-end are charged to cost of goods sold at the actual LIFO cost of the layers liquidated. The inventory decrement as of March 31, 2016 is expected to be restored prior to year-end and the inventory decrement as of March 31, 2015 was restored prior to December 31, 2015.
Our retail operations, wholesale services and midstream operations segments carry inventory at LOCOM, where cost is determined on a WACOG basis. For the periods presented, we recorded LOCOM adjustments to cost of goods sold in the following amounts to reduce the value of our natural gas inventories to market value.

Accounting Developments
Accounting standards adopted in 2016
Effective January 1, 2016, we adopted the accounting guidance described below, none of which had a material impact on our unaudited condensed consolidated financial statements. For additional information on these accounting standards, see Note 3 to our consolidated financial statements and related notes included in Item 8 of our 2015 Form 10-K.
accounting for a share-based compensation performance target that could be achieved after the requisite service period;
consolidation of other legal entities into our financial statements;
accounting for fees paid in connection with arrangements with cloud-based software providers; and
reducing the diversity in fair value measurements hierarchy disclosures.
Other newly issued accounting standards and updated authoritative guidance
In March 2016, the FASB issued updated authoritative guidance related to accounting for certain aspects of share-based payment transactions. The new guidance changes the income tax accounting related to the tax "windfall" or "shortfall" on share-based compensation, increases the tax withholding level allowed before triggering liability classification of the award and allows for a policy election to account for forfeitures as they occur. This guidance is effective for us beginning January 1, 2017, and early adoption is permitted. We are currently evaluating the potential impact of this new guidance.
In February 2016, the FASB issued updated authoritative guidance related to accounting for lease transactions. The new guidance will require all organizations that use leased assets, referred to as "lessees," to recognize all leases with terms of more than 12 months on the balance sheet as right of use assets and corresponding liabilities. Lessees will continue to recognize lease expense based on classification of the lease, using a straight-line expense pattern for operating leases and a front-loaded expense pattern for financing leases. The accounting for lessors is substantially equivalent to the existing guidance. It also requires additional disclosures, both qualitative and quantitative, including amount, timing, and uncertainty of cash flows arising from leases. The new guidance is effective for us beginning January 1, 2019 and must be applied using the modified retrospective approach to each prior period presented. Early adoption of this new guidance is permitted. We are currently evaluating the potential impact of this new guidance.
In January 2016, the FASB issued updated authoritative guidance related to classification and measurement of financial instruments. The amendments modify the accounting and presentation for certain financial liabilities and equity investments not consolidated or reported using the equity method. The guidance is effective for us beginning January 1, 2018, and limited early adoption is permitted. We are currently evaluating the potential impact of this new guidance, but do not anticipate that it will have a material impact on our consolidated financial statements.
In November 2015, the FASB issued updated authoritative guidance related to the balance sheet classification of deferred taxes, which requires companies to present deferred income tax assets and deferred income tax liabilities as noncurrent on a classified balance sheet instead of the current requirement to separate deferred income tax liabilities and assets into current and noncurrent amounts. The guidance is effective for us beginning January 1, 2017, and early application is permitted either prospectively or retrospectively. We have determined that this new guidance will not have a material impact on our consolidated financial statements.
In July 2015, the FASB issued an update to authoritative guidance to simplify the measurement of certain inventories. Under the new guidance, inventories are required to be measured at the lower of cost and net realizable value, the latter representing the estimated selling price in the ordinary course of business, reduced by costs of completion, disposal and transportation. Under current guidance, inventories are required to be measured at the lower of cost or market, but depending upon specific circumstances, market could refer to replacement cost, net realizable value, or net realizable value reduced by a normal profit margin. The amendments do not apply to inventories carried on a LIFO basis, which for us applies only to our Nicor Gas inventories. The guidance is to be applied prospectively, is effective for us beginning January 1, 2017, and early adoption is permitted. We are currently evaluating the potential impact of this new guidance.

In May 2014, the FASB issued an update to authoritative guidance related to revenue from contracts with customers. The update replaces most of the existing guidance with a single set of principles for recognizing revenue from contracts with customers. In July 2015, the FASB delayed the effective date by one year and the guidance will now be effective for us beginning January 1, 2018. Early adoption of the standard is permitted, but not before the original effective date of December 15, 2016. The new guidance must be applied retrospectively to each prior period presented or via a cumulative effect upon the date of initial application. We have not determined the impact of this new guidance, nor have we selected a transition method.
Note 4 - Regulated Operations
The accounting policies for our regulated operations are described within "Regulated Operations" in Note 3 to our consolidated financial statements and related notes included in Item 8 of our 2015 Form 10-K.

Base rates are designed to provide the opportunity to recover cost and earn a return on investment during the period rates are in effect. As such, all of our regulatory assets recoverable through base rates are subject to review by the respective state regulatory agency during future rate proceedings. We are not aware of evidence that these costs will not be recoverable through either rate riders or base rates, and we believe that we will be able to recover such costs consistent with our historical recoveries.

In October 2015, Atlanta Gas Light received an order from the Georgia Commission, which included a final determination of the true-up recovery related to the PRP that allows Atlanta Gas Light to recover $144 million of the $178 million of incurred and allowed costs that were deferred for future recovery.
Deferred/Accrued Natural Gas Costs We charge our utility customers for natural gas consumed using natural gas cost recovery mechanisms established by the state regulatory agencies. Under these mechanisms, all prudently incurred natural gas costs are passed through to customers without markup, subject to regulatory review. We defer or accrue the difference between the actual cost of gas and the amount of commodity revenue earned in a given period, such that no operating margin is recognized related to these costs. The deferred or accrued amount is either billed or refunded to our customers prospectively through adjustments to the commodity rate.
Environmental Remediation Costs We are subject to federal, state and local laws and regulations governing environmental quality and pollution control that require us to remove or remedy the effect on the environment of the disposal or release of specified substances at our current and former operating sites, substantially all of which is related to former MGP sites. The ERC assets and liabilities are associated with our distribution operations segment and remediation costs are generally recoverable from customers through rate mechanisms approved by regulators. Accordingly, both costs incurred to remediate the former MGP sites, plus the future estimated cost recorded as liabilities, net of amounts previously collected, are recognized as a regulatory asset until recovered from customers.
Our accrued environmental remediation liabilities are estimates of future remediation costs for investigation and cleanup of our current and former operating sites that are contaminated. These estimates are determined using engineering-based estimates and probabilistic models of potential costs when such estimates cannot be made, on an undiscounted basis. These estimates contain various assumptions, which we refine and update on an ongoing basis. These liabilities do not include other potential expenses, such as unasserted property damage claims, personal injury or natural resource damage claims, legal expenses or other costs for which we may be held liable but for which we cannot reasonably estimate an amount.
Our accrued environmental remediation liabilities are not regulatory liabilities; however, the associated expenses are deferred as corresponding regulatory assets until the costs are recovered from customers. We primarily recover these deferred costs through rate riders that authorize dollar-for-dollar recovery. We expect to collect $21 million in revenues over the next 12 months, which is reflected as a current regulatory asset. The following table provides additional information on the estimated costs to remediate our current and former operating sites as of March 31, 2016.

Nicor Gas is responsible in whole or in part for 26 MGP sites, two of which have been remediated and their use is no longer restricted by the environmental condition of the property. Nicor Gas and Commonwealth Edison Company are parties to an agreement to cooperate in cleaning up residue at 23 of the sites. Nicor Gas’ allocated share of cleanup costs for these sites is 52%.

We have no regulatory recovery mechanism for the site in North Carolina and there is no amount included within our regulatory assets. Changes in estimated costs are recognized in income during the period of change.
Regulatory Infrastructure Programs An update to our infrastructure improvement programs at our utilities is as follows.
Virginia Natural Gas In March 2016, the Virginia Commission approved an extension to our original Steps to Advance Virginia's Energy (SAVE) program, under which Virginia Natural Gas is allowed to invest up to $210 million on qualifying infrastructure projects through 2021 to replace more than 200 miles of aging pipeline infrastructure.

Note 6 - Derivative Instruments
Our objectives and strategies for using derivative instruments, and the related accounting policies and methods used to determine their fair values are described within "Fair Value Measurements" in Note 3 to our consolidated financial statements and related notes included in Item 8 of our 2015 Form 10-K. See Note 5 herein for additional information on the fair value of our derivative instruments. Certain of our derivative instruments contain credit-risk-related or other contingent features that could require us to post collateral in the normal course of business when our financial instruments are in net liability positions. As of March 31, 2016, December 31, 2015 and March 31, 2015, for agreements with such features, derivative instruments with liability fair values totaled $65 million, $46 million and $52 million, respectively, for which we had posted no collateral to our counterparties as we exceed the minimum credit rating requirements. As of March 31, 2016, the maximum collateral that could have been required with these features was less than $1 million. For additional information on our credit-risk-related contingent features, see “Energy Marketing Receivables and Payables” in Note 3 to our consolidated financial statements and related notes included in Item 8 of our 2015 Form 10-K. Our derivative instrument activities are included within operating cash flows as increases to net income of $51 million and $33 million for the three months ended March 31, 2016 and 2015, respectively.
Quantitative Disclosures Related to Derivative Instruments
Our derivative instruments include both long and short natural gas positions. A long position is a contract to purchase natural gas, and a short position is a contract to sell natural gas. As of the dates presented, we had natural gas contracts outstanding in the following quantities:

reclassified from OCI into cost of goods sold, operation and maintenance expense, interest expense and operating revenues to be recognized on our unaudited Condensed Consolidated Statements of Income over the next 12 months are $4 million. These deferred losses are related to natural gas derivative contracts associated with retail operations’ and Nicor Gas’ system use and our interest rate swaps. The expected losses are based upon the fair values of these financial instruments at March 31, 2016. The effective portions of gains and losses on derivative instruments qualifying as cash flow hedges that were recognized in OCI during the periods are presented on our unaudited Condensed Consolidated Statements of Income. See Note 9 for these amounts.

Interest rates are calculated based on the daily weighted average balance outstanding for the three months ended March 31, 2016 and 2015.
(2)
As of March 31, 2016, the effective interest rates on our commercial paper borrowings were 0.8% for AGL Capital and 0.6% for Nicor Gas.
Commercial Paper Programs
We maintain commercial paper programs at AGL Capital and at Nicor Gas that consist of short-term, unsecured promissory notes used in conjunction with cash from operations to fund our seasonal working capital requirements. Working capital needs fluctuate during the year and are highest during the injection period in advance of the Heating Season. Nicor Gas’ commercial paper program supports working capital needs at Nicor Gas, while all of our other subsidiaries and SouthStar participate in AGL Capital’s commercial paper program. During the first three months of 2016, our commercial paper maturities ranged from 1 to 59 days, and at March 31, 2016, remaining terms to maturity ranged from 1 to 46 days. During the first three months of 2016, there were no commercial paper issuances with original maturities over three months.
Long-Term Debt
On February 1, 2016, $75 million of Nicor Gas first mortgage bonds matured and were repaid using the proceeds from commercial paper borrowings.
On January 23, 2015, we executed $800 million in notional value of 10-year and 30-year fixed-rate forward-starting interest rate swaps to hedge potential interest rate volatility prior to our senior note issuance in the fourth quarter of 2015 and our anticipated issuances in 2016. We have designated the forward-starting interest rate swaps, which are settled on the respective debt issuance dates, as cash flow hedges. We settled $200 million of these interest rate swaps on November 18, 2015, in conjunction with the aforementioned senior note issuance. We performed a qualitative assessment of effectiveness on the remaining interest rate swaps as of March 31, 2016 and concluded that the remaining hedges are highly effective.
Financial and Non-Financial Covenants
The AGL Credit Facility and the Nicor Gas Credit Facility each include a financial covenant that requires us to maintain a ratio of total debt to total capitalization of no more than 70% at the end of any month. The following table contains our debt-to-capitalization ratios for the dates presented, which are below the maximum allowed.

As defined in our credit facilities, these ratios include standby letters of credit and performance/surety bonds and exclude accumulated OCI items related to non-cash pension adjustments, welfare benefits liability adjustments and accounting for cash flow hedges.
The credit facilities contain certain non-financial covenants that, among other things, restrict liens and encumbrances, loans and investments, acquisitions, dividends and other restricted payments, asset dispositions, mergers and consolidations, and other matters customarily restricted in such agreements.
Default Provisions
Our credit facilities and other financial obligations include provisions that, if not complied with, could require early payment or similar actions. The most important default events include the following:
a maximum leverage ratio;
insolvency events and/or nonpayment of scheduled principal or interest payments;
acceleration of other financial obligations; and
change of control provisions.
We have no triggering events in our debt instruments that are tied to changes in our specified credit ratings or our stock price and have not entered into any transaction that requires us to issue equity based on credit ratings or other triggering events. We were in compliance with all existing debt provisions and covenants, both financial and non-financial, for all periods presented.

Note 10 - Non-Wholly Owned Entities and Contingently Redeemable Noncontrolling Interest
SouthStar, a joint venture owned by us and Piedmont, is our only VIE for which we are the primary beneficiary. For additional information on SouthStar, see Note 11 to our consolidated financial statements and related notes included in Item 8 of our 2015 Form 10-K. Earnings from SouthStar in 2016 and 2015 were allocated entirely in accordance with the ownership interests.
On December 9, 2015, we notified Piedmont of our election, in accordance with the change in control provisions in the Second Amended and Restated Limited Liability Company Agreement of SouthStar, to purchase Piedmont’s remaining 15% interest in SouthStar at fair market value. This purchase is contingent upon the closing of the merger between Piedmont and Duke Energy Corporation, which is subject to various closing conditions that are beyond our control and is expected to be completed in 2016. On February 12, 2016, we and Piedmont agreed to various terms of this purchase, including a fair market value of $160 million. During the first quarter of 2016, we reclassified the noncontrolling interest related to Piedmont's 15% interest in SouthStar, whose redemption is beyond our control, as a contingently redeemable noncontrolling interest. Previously, this noncontrolling interest was included in equity. If our purchase of this noncontrolling interest is completed, the difference between the purchase price and the amount of noncontrolling interest will be recorded in equity.
A roll-forward of the contingently redeemable noncontrolling interest is detailed below:

Cash flows used in our investing activities include capital expenditures for SouthStar of $1 million and $1 million for the three months ended March 31, 2016 and 2015, respectively. Cash flows used in our financing activities include SouthStar’s distribution to Piedmont for its portion of SouthStar’s annual earnings from the previous year, which generally occurs in the first quarter of each fiscal year. For the three months ended March 31, 2016 and 2015, SouthStar distributed $19 million and $18 million, respectively, to Piedmont. SouthStar’s counterparties have no recourse to our general credit beyond our corporate guarantees that we have provided to SouthStar’s counterparties and natural gas suppliers. The following table provides additional information on SouthStar’s assets and liabilities as of the dates presented. The SouthStar amounts exclude intercompany eliminations and the balances of our wholly-owned subsidiary with an 85% ownership interest in SouthStar.

Note 11 - Commitments, Guarantees and Contingencies
We incur various contractual obligations and financial commitments in the normal course of business that are reasonably likely to have a material effect on liquidity or the availability of capital resources. Contractual obligations include future cash payments required under existing contractual arrangements, such as debt and lease agreements. These obligations may result from both general financing activities and commercial arrangements that are directly supported by related revenue-producing activities.
We are also involved in legal or administrative proceedings before various courts and agencies with respect to general claims, environmental remediation and other matters. While we are unable to determine the ultimate outcomes of these contingencies, we believe that our financial statements appropriately reflect these amounts, including the recording of liabilities when a loss is probable and reasonably estimable. For more information on these matters, see Note 12 to our consolidated financial statements and related notes included in Item 8 of our 2015 Form 10-K.
Contingencies and Guarantees
Contingent financial commitments, such as financial guarantees, represent obligations that become payable only if certain predefined events occur. We have certain subsidiaries that enter into various financial and performance guarantees and indemnities providing assurance to third parties. We believe the likelihood of payment under our guarantees is remote. No liabilities have been recorded for such guarantees and indemnifications, as the fair values were inconsequential at inception.
Regulatory Matters
In August 2014, staff of the Illinois Commission and the CUB filed testimony in the Nicor Gas 2003 gas cost prudence review disputing certain gas loan transactions offered by Nicor Gas under its Chicago Hub services and requesting refunds of $18 million and $22 million, respectively. We filed surrebuttal testimony in December 2014 disputing that any refund is due, as Nicor Gas was authorized to enter into these transactions and revenues associated with such transactions reduced ratepayers’ costs as either credits to the PGA or reductions to base rates consistent with then-current Illinois Commission orders governing these activities. In July 2015, the Administrative Law Judge issued a proposed order concluding that Nicor Gas’ supply costs and purchases in 2003 were prudent, its reconciliation of the related costs was proper, and the propositions by the staff of the

Glossary of Key Terms

Table of Contents

Illinois Commission and the CUB were based on hindsight speculation, which is expressly prohibited in a prudence review examination. In November 2015, the Illinois Commission granted the CUB's petition for a rehearing on this matter. In February 2016, the Administrative Law Judge issued a proposed order on the rehearing affirming the original order by the Illinois Commission, which was approved by the Illinois Commission in March 2016.
Environmental Matters
We are subject to federal, state and local laws and regulations governing environmental quality and pollution control that require us to remove or remedy the effect on the environment of the disposal or release of specified substances at our current and former operating sites. See Note 4 herein for additional information on our environmental remediation costs.
In September 2015, the Environmental Protection Agency filed an administrative complaint and notice of opportunity for hearing against Nicor Gas. The complaint alleges violation of the regulatory requirements applicable to polychlorinated biphenyls in the Nicor Gas distribution system and the Environmental Protection Agency seeks a total civil penalty of approximately $0.3 million. While we are unable to predict the ultimate outcome of this matter, the final disposition of this matter is not expected to have a material adverse impact on our liquidity or financial condition.
Litigation
We are involved in litigation arising in the normal course of business. Although in some cases we are unable to estimate the amount of loss reasonably possible in addition to any amounts already recognized, it is possible that the resolution of these contingencies, either individually or in aggregate, will require us to take charges against, or will result in reductions in, future earnings. Management believes that while the resolutions of these contingencies, whether individually or in aggregate, could possibly be material to earnings in a particular quarter, they will not have a material adverse effect on our consolidated balance sheets or cash flows for the year. For additional litigation information, see Note 12 to our consolidated financial statements and related notes included in Item 8 of our 2015 Form 10-K.
Note 12 - Segment Information
Our reportable segments comprise revenue-generating components of the company for which we produce separate financial information internally that we regularly use to make operating decisions and assess performance. Our determination of reportable segments considers the strategic operating units under which we manage sales of various products and services to customers in differing regulatory environments. We manage our businesses through four reportable segments – distribution operations, retail operations, wholesale services and midstream operations. Our non-reportable segments are combined and presented as “other.”
Our distribution operations segment is the largest component of our business and includes natural gas local distribution utilities that construct, manage and maintain intrastate natural gas pipelines and distribution facilities in seven states. Although the operations of this segment are geographically dispersed, the operating subsidiaries within the segment have similar economic and risk characteristics as they are regulated utilities with rates determined by individual state regulatory agencies.
We are also involved in several related and complementary businesses. Our retail operations segment includes retail natural gas marketing to end-use customers primarily in Georgia and Illinois. Additionally, retail operations provides home equipment protection products and services. Our wholesale services segment engages in natural gas storage and gas pipeline arbitrage and related activities. Additionally, this segment provides natural gas asset management and/or related logistics services for each of our utilities except Nicor Gas, as well as for non-affiliated companies. Our midstream operations segment includes our non-utility storage and pipeline operations, including the operation of high-deliverability natural gas storage assets. Our other segment includes subsidiaries that are not significant on a stand-alone basis and that do not align with one of our reportable segments.
The chief operating decision maker of the company is the President and Chief Executive Officer, who utilizes EBIT as the primary measure of profit and loss in assessing the results of each segment’s operations. EBIT includes operating income (loss) and other income and expenses and excludes income taxes and interest expense, which we evaluate on a consolidated basis. Summarized statements of income, balance sheets and capital expenditure information by segment as of, and for the periods presented, are shown in the following tables.

ITEM 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.
The following discussion and analysis should be read in conjunction with our unaudited condensed consolidated financial statements and the related notes in this quarterly filing, as well as with our 2015 Form 10-K. Results for the interim periods presented are not necessarily indicative of the results to be expected for the full fiscal period due to seasonal and other factors.
Forward-Looking Statements
Certain expectations and projections regarding our future performance referenced in this section and elsewhere in this report, as well as in other reports and proxy statements we file with the SEC or otherwise release to the public and on our website, are forward-looking statements and are subject to uncertainties and risks. Senior officers and other employees may also make verbal statements to analysts, investors, regulators, the media and others that are forward-looking.
Forward-looking statements often include words such as "anticipate," "assume," "believe," "can," "could," "estimate," "expect," "forecast," "future," "goal," "indicate," "intend," "may," "outlook," "plan," "potential," "predict," "project," "proposed," "seek," "should," "target," "would" or similar expressions. You are cautioned not to place undue reliance on forward-looking statements.
While we believe that our expectations are reasonable in view of the information that we currently have, these expectations are subject to future events, risks and uncertainties, and there are numerous factors – many of which are beyond our control – that could cause actual results to vary materially from these expectations. Such events, risks and uncertainties include, but are not limited to:
certain risks and uncertainties associated with the proposed merger with Southern Company, including, without limitation:
the possibility that the proposed merger does not close due to the failure to satisfy the closing conditions, including, but not limited to, a failure to obtain the remaining required regulatory approvals;
delays caused by the remaining required regulatory approvals, which may delay the proposed merger or cause the companies to abandon the transaction;
disruption from the proposed merger making it more difficult to maintain our business and operational relationships and the risk that unexpected costs will be incurred during this process;
the diversion of management time on merger-related issues; and
the timing of our last quarterly dividend to holders of our common stock, if any, declared prior to the potential closing of the proposed merger with Southern Company;
changes in price, supply and demand for natural gas and related products;
the impact of changes in state and federal legislation and regulation, including any changes related to climate matters;
actions taken by government agencies on rates and other matters;
concentration of credit risk;
utility and energy industry consolidation;
the impact on cost and timeliness of construction projects, including our pipeline projects, from government and other approvals, project delays, adequacy of supply of diversified vendors and unexpected changes in project costs;
the cost of funds to finance our construction projects and our ability to recover certain project costs from our customers;
limits on pipeline capacity;
the impact of acquisitions and divestitures;
our ability to successfully integrate operations that we have or may acquire or develop in the future;
direct or indirect effects on our business, financial condition or liquidity resulting from a change in our credit ratings or the credit ratings of our counterparties or competitors;
interest rate fluctuations;
financial market conditions, including disruptions in the capital markets and lending environment;
general economic conditions;
uncertainties about environmental issues and the related impact of such issues, including our environmental remediation plans;
the capacity of our gas storage caverns, which are subject to natural settling and other occurrences;
contracting rates at our midstream operations storage business;
the impact of weather on the temperature-sensitive portions of our business;
the impact of natural disasters, such as hurricanes, on the supply and price of natural gas;
acts of war or terrorism;
the outcome of litigation;
the effect of accounting pronouncements issued by standard-setting bodies; and
the other factors discussed elsewhere herein and in our other filings with the SEC.
There also may be other factors that we do not anticipate or that we do not recognize as material that could cause results to differ materially from our expectations. Forward-looking statements speak only as of the date they are made. We expressly

disclaim any obligation to update or revise any forward-looking statement, whether as a result of future events, new information or otherwise, except as required by law.
Executive Summary
We are an energy services holding company whose principal business is the safe, reliable and cost-effective distribution of natural gas in seven states – Illinois, Georgia, Virginia, New Jersey, Florida, Tennessee and Maryland – through our seven natural gas distribution utilities. We are also involved in several businesses that are complementary to our primary business. We have four reportable segments – distribution operations, retail operations, wholesale services and midstream operations - and one non-reportable segment – other. These segments are consistent with how management views and operates our business. For additional information on our reportable segments, see Note 12 to our unaudited condensed consolidated financial statements under Part I, Item 1 herein and Item 1, “Business” of our 2015 Form 10-K.
Proposed Merger With Southern Company In August 2015, we entered into the Merger Agreement with Southern Company, which, based on the number of common shares and the fair value of debt outstanding as of March 31, 2016, reflects an estimated business enterprise value of AGL Resources of $12.7 billion that includes an equity value of $8.0 billion. When the merger becomes effective, which is expected to occur in the second half of 2016, each share of our common stock, other than certain excluded shares, will convert into the right to receive $66 in cash, without interest, less any applicable withholding taxes. Completion of the merger is conditioned upon, among other things, the approval of certain state regulatory agencies. At closing, the transaction is expected to create the second largest utility in the U.S. based on customer base, and we will become a wholly owned subsidiary of Southern Company, but continue to maintain our own management team.
To date, the proposed merger has been approved by the Maryland Commission, the Georgia Commission, the California Public Utilities Commission, the Virginia Commission and our shareholders. Additionally, we received consent from the Federal Communications Commission to transfer parent company control of radio licenses held by certain of our subsidiaries, and the waiting period under the Hart-Scott-Rodino Act has expired.
For additional information relating to this transaction, see Note 2 to our unaudited condensed consolidated financial statements under Part I, Item 1 herein and the definitive proxy statement contained in Schedule 14A filed with the SEC on October 13, 2015.
Business Objectives Several of our specific business objectives are detailed as follows:

Distribution Operations: Invest necessary capital to enhance and maintain safety and reliability in delivering natural gas; remain an efficiency leader within the industry while maintaining a focus on customer satisfaction; expand the natural gas distribution system and educate energy consumers on the benefits of converting to natural gas. We continue to invest in our regulatory infrastructure programs to minimize the lag in recovery of our capital expenditures. Additionally, we continue to effectively manage our costs and leverage our shared services model across our businesses to combat inflationary effects.
Nicor Gas In July 2014, the Illinois Commission approved our nine-year regulatory infrastructure program, Investing in Illinois, under which we implemented monthly surcharge rates beginning March 2015. As of March 31, 2016, we have placed into service $276 million of qualifying assets under this program, $26 million of which was related to the first quarter of 2016. We expect to invest $281 million during 2016.
Atlanta Gas Light Atlanta Gas Light's Strategic Infrastructure Development and Enhancement (STRIDE) program, which started in 2009, consists of three individual programs that update and expand distribution systems and liquefied natural gas facilities as well as improve system reliability to meet operational flexibility and customer growth. Through the programs under STRIDE, we expect to invest $169 million during 2016, $30 million of which was incurred during the first quarter of 2016.
Elizabethtown Gas In September 2015, Elizabethtown Gas filed the Safety, Modernization and Reliability Tariff (SMART) plan with the New Jersey BPU seeking approval to invest more than $1.1 billion to replace 630 miles of vintage cast iron, steel and copper pipeline, as well as 240 regulator stations. If approved, the program is expected to be completed by 2027. As currently proposed, costs incurred under the program would be recovered primarily through a rider surcharge over a period of 10 years.
The New Jersey BPU approved the extension of our Aging Infrastructure Replacement (AIR) program in August 2013, under which we expect to invest $29 million in 2016, $7 million of which was incurred during the first quarter of 2016. As part of this approval, we agreed and are on track to file a general rate case by September 2016.
Virginia Natural Gas In March 2016, the Virginia State Commission approved the SAVE II infrastructure replacement project, under which Virginia Natural Gas expects to invest $30 million on qualifying infrastructure projects in 2016, $7 million of which was incurred during the first quarter of 2016, and up to $35 million annually thereafter through 2021 to replace more than 200 miles of aging pipeline infrastructure.
Florida City Gas The Florida Commission approved Florida City Gas' Safety, Access and Facility Enhancement (SAFE) program in September 2015. Under the program, Florida City Gas will spend approximately $10 million

Table of Contents

annually over a 10-year period on infrastructure relocation and enhancement projects. Expenditures of $1 million were incurred during the first quarter of 2016. Costs incurred under the program will be recovered through a rate rider with annual rate adjustments and true-ups.
Retail Operations: Maintain our current customer base in Georgia and Illinois while continuing to expand into other profitable retail markets and expand our warranty businesses through partnership opportunities with affiliates and third parties. We will focus on products that are responsive to our customers' needs.
We entered into an agreement with Piedmont to purchase its remaining 15% interest in SouthStar for $160 million. This transaction is contingent upon the closing of the merger between Piedmont and Duke Energy Corporation, which is expected to occur in 2016.
Wholesale Services: Position our business to secure sufficient supplies of natural gas to meet the needs of our utility and third-party customers and to hedge natural gas prices to manage costs effectively, reduce price volatility and maintain a competitive advantage relative to other marketers.
Midstream Operations: Invest in natural gas based projects, some of which remain subject to regulatory approvals, along with our existing pipelines and storage facilities to support our efforts to provide diverse sources of natural gas supplies to our customers, resolve current and long-term supply planning for new capacity, enhance system reliability and generate economic development in the areas served.
During the first quarter of 2016, FERC staff announced that it intends to release the final environmental review for the PennEast Pipeline project in December 2016. Given this updated timing, we expect to receive FERC approval in 2017.
Natural Gas Market Fundamentals Volatility in the natural gas market arises from a number of factors, such as weather fluctuations or changes in supply or demand for natural gas in different regions of the country. The volatility of natural gas commodity prices has a significant impact on our customer rates, our long-term competitive position against other energy sources and the ability of our retail operations and wholesale services segments to capture value from location and seasonal spreads. Additionally, changes in commodity prices subject a significant portion of our operations to earnings variability.
Our non-utility businesses principally use physical and financial arrangements to reduce the risks associated with fluctuations in market conditions and changing commodity prices. These economic hedges may not qualify, or may not be designated, for hedge accounting treatment. As a result, our reported earnings for wholesale services, retail operations and midstream operations reflect changes in the fair values of certain derivatives. A general decline in natural gas prices or a narrowing of transportation spreads generally results in derivative gains and corresponding increases in EBIT, while an increase in natural gas prices or a widening of transportation spreads generally results in derivative losses and corresponding decreases in EBIT. These values may change significantly from period to period and are reflected as gains or losses within our operating revenues or our OCI for those derivative instruments that qualify, and are designated, as accounting hedges.
We generate the majority of our operating revenues through the sale, distribution and storage of natural gas. We include in our consolidated revenues an estimate of revenues from natural gas distributed, but not yet billed to residential, commercial and industrial customers from the date of the last bill to the end of the reporting period. No individual customer or industry accounts for a significant portion of our revenues. Our revenues declined in 2016 as compared to 2015 primarily due to lower volumes of gas sold to customers and hedge losses due to weather in the first three months of 2016 that was warmer than the colder-than-normal weather in the first three months of 2015 and the resulting lower natural gas prices in 2016 compared to 2015.
Our operating results can vary significantly from quarter to quarter as a result of the seasonality of operating revenues and EBIT at distribution operations and retail operations. During the Heating Season, natural gas usage and operating revenues are generally higher, as more customers are connected to our distribution systems and natural gas usage is higher in periods of colder weather. Alternatively, our base operating expenses, excluding cost of gas, revenue taxes and certain incentive compensation costs, are incurred relatively evenly over any given year, resulting in variability in the quarterly pattern of earnings.
Performance and Non-GAAP Measures We evaluate segment performance using the measures of EBIT and operating margin. EBIT includes operating income and other income and expenses and excludes interest expense and income taxes, which we evaluate on a consolidated basis. Operating margin is a non-GAAP measure that is calculated as operating revenues minus cost of goods sold and revenue tax expense in distribution operations. Operating margin excludes operation and maintenance expenses, depreciation and amortization, taxes other than income taxes and merger-related expenses, which are included in our calculation of operating income as calculated in accordance with GAAP and reflected on our unaudited Condensed Consolidated Statements of Income.
We believe that the presentation of operating margin provides useful information to management and investors regarding the contribution resulting from customer growth in our distribution operations segment since the cost of goods sold and revenue tax expenses can vary significantly and are generally billed directly to our customers. We further believe that operating margin at our retail operations, wholesale services and midstream operations segments allows us to focus on a direct measure of operating margin before overhead costs.

Table of Contents

We present the non-GAAP measure of diluted earnings per share - as adjusted, which excludes merger-related expenses as we do not regularly engage in transactions of the magnitude of the proposed merger with Southern Company. Consequently, we do not regularly incur merger expenses and believe that presenting diluted earnings per share excluding merger-related expenses provides investors with an additional measure of our core operating performance.
Operating margin and diluted earnings per share - as adjusted should not be considered as alternatives to, or more meaningful indicators of, our operating performance than net income attributable to AGL Resources, operating income or diluted earnings per share as determined in accordance with GAAP. In addition, our operating margin and diluted earnings per share - as adjusted may not be comparable to similarly titled measures of other companies.
Summary of Results:
The table below reconciles (i) operating revenues and operating margin to operating income, (ii) EBIT to income before income taxes and net income and (iii) diluted earnings per share - as adjusted to diluted earnings per common share as calculated in accordance with GAAP, together with other consolidated financial information for the periods presented.

2016 Results For the first quarter of 2016, our net income attributable to AGL Resources was $182 million, a decrease of $11 million compared to the same period in 2015. This decrease was due primarily to lower consolidated EBIT of $16 million largely driven by a $22 million negative weather impact, net of hedge costs, due to warmer-than-normal weather during 2016 compared to colder-than-normal weather in 2015, a $12 million EBIT decrease at wholesale services and $3 million in merger-related expenses in 2016. The remaining net EBIT increase of $21 million in 2016 over 2015 was due primarily to higher operating margin at distribution operations from infrastructure programs and increased non-weather consumption through usage and customer growth. Further discussion of the year-over-year drivers are detailed at the segment level within "Results of Operations" below.
Results of Operations
Operating Metrics
Weather We measure weather and its effect on our business using Heating Degree Days. Generally, increased Heating Degree Days result in higher demand for gas on our distribution systems. With the exception of Nicor Gas and Florida City Gas, we have regulatory mechanisms, such as weather normalization, which limit our exposure to weather changes within typical ranges in each of our utilities’ respective service areas. However, our utility customers in Illinois and our retail operations customers primarily in Georgia can be impacted by warmer- or colder-than-normal weather. Additionally, we utilize weather hedges to reduce negative earnings impacts in the event of warmer-than-normal weather, while retaining all of the earnings upside in the event of colder-than-normal weather for distribution operations in Illinois and most of the earnings upside for our retail operations. We also consider operating costs that may vary with the effects of weather, particularly in periods that are significantly colder-than-normal. The following table presents the Heating Degree Days information for those locations.

Normal represents the 10-year average from January 1, 2006 through March 31, 2015 for Illinois at Chicago Midway International Airport and for Georgia at Atlanta Hartsfield-Jackson International Airport, as obtained from the National Oceanic and Atmospheric Administration, National Climatic Data Center.
(2)
The 10-year average Heating Degree Days established by the Illinois Commission in our last rate case is 2,902 for the first three months from 1998 through 2007.
In the first quarter of 2016, the unfavorable weather-related EBIT impact from the warmer-than-normal weather on distribution operations was limited to $6 million, net of the impact of our weather hedging. Our retail operations in Georgia did not experience an unfavorable weather-related EBIT impact in the current quarter. The total net unfavorable weather impact on the first quarter of 2016 was $5 million, compared to a $17 million favorable weather impact for the same period in 2015, when weather was significantly colder-than-normal.
Customers The number of customers at distribution operations and energy customers at retail operations can be impacted by natural gas prices, economic conditions and competition from alternative fuels. Our energy customers at retail operations are primarily located in Georgia and Illinois. Our customer metrics presented in the following table highlight the average number of customers to which we provide services for the specified periods.

We anticipate overall customer growth trends at distribution operations for 2016 to continue improving based on an expectation of continued improvement in the housing market and continued low natural gas prices.
Retail operations’ market share in Georgia has decreased slightly primarily as a result of a highly competitive marketing environment, which we expect to continue for the foreseeable future. We will continue efforts in our retail operations segment to enter into targeted markets and expand our energy customers and service contracts.

Within midstream operations, our natural gas storage businesses seek to have a significant portion of their working natural gas capacity under firm subscription, but also take into account current and expected market conditions. This allows our natural gas storage business to generate additional revenue during times of peak market demand for natural gas storage services, but retain some consistency with its earnings and maximize the value of its investments.

Our midstream operations storage business is cyclical, and the abundant supply of natural gas in recent years and resulting lack of market and price volatility have negatively impacted the profitability of our storage facilities. The prices for natural gas storage capacity are expected to increase as supply and demand quantities reach equilibrium with continued economic improvement, expected exports of liquefied natural gas, and projected demand increases in response to low prices and expanded uses for natural gas. Annual subscription rates are typically recontracted on March 31 of each fiscal year and the following table illustrates the overall monthly average firm subscription rates per storage facility and the amount of firm capacity subscription as of April 1, 2016 and 2015. These amounts exclude 5.0 Bcf contracted by Sequent as of April 1, 2015, at an average monthly rate of $0.070. Sequent had no capacity subscribed as of April 1, 2016.

Distribution Operations
Our distribution operations segment is the largest component of our business and is subject to regulation and oversight by agencies in each of the states we serve. These agencies approve natural gas rates designed to provide us the opportunity to generate revenues to recover the cost of natural gas delivered to our customers and our fixed and variable costs, such as depreciation, interest, maintenance and overhead costs, and to earn a reasonable return for our shareholders.
With the exception of Atlanta Gas Light, our second largest utility, the earnings of our regulated utilities can be affected by customer consumption patterns that are a function of weather conditions, price levels for natural gas and general economic conditions that may impact our customers’ ability to pay for natural gas consumed. We have various weather mechanisms, such as weather normalization mechanisms and weather derivative instruments, that limit our exposure to weather changes within typical ranges in their respective service areas. For the three months ended March 31, 2016, distribution operations’ EBIT increased by $6 million, or 3%, compared to the same period during the prior year, as shown in the following table.

Wholesale Services
Our wholesale services segment is involved in asset management and optimization, storage, transportation, producer and peaking services, natural gas supply, natural gas services and wholesale marketing. We have positioned the business to generate positive economic earnings even under low volatility market conditions that can result from a number of factors, including weather fluctuations and changes in supply or demand for natural gas in different regions of the country. However, when market price volatility increases as we experienced in 2015, we are well positioned to capture significant value and generate stronger results. For the three months ended March 31, 2015, wholesale services delivered strong EBIT due to increased levels of

Change in commercial activity The commercial activity at wholesale services includes recognized storage and transportation values that were generated in prior periods, which reflect the impact of prior period hedge gains and losses as associated physical transactions occur in the period. Additionally, the commercial activity includes operating margin generated and recognized in the current period. For the three months ended March 31, 2016, commercial activity decreased due to:
Lower price volatility as compared to last year due to the colder-than-normal weather in 2015; and
Higher operating margin of $8 million resulting from the withdrawal of storage inventory hedged at the end of 2015 that was included in the storage withdrawal schedule.
While we experienced unusually high and low volatility in natural gas prices in early 2015 and 2016, respectively, due partly to weather, in the near term we anticipate low volatility in certain areas of our portfolio. Over the longer term, we expect volatility to be low to moderate and locational or transportation spreads to decrease over time as new pipelines are built to reduce the existing supply constraints in the shale areas of the Northeast U.S. To the extent these pipelines are delayed or not built, volatility could increase. Natural gas supply increases during the 2015/2016 Heating Season along with the warmer-than-normal weather we experienced resulted in record natural gas inventories that contributed to reduced natural gas prices. Additional economic factors may contribute to this environment, including the significant drop in oil and natural gas prices, which could lead to consolidation of natural gas producers or reduced levels of natural gas production. Further, if economic conditions continue to improve, the demand for natural gas may increase, which may cause natural gas prices to rise and drive higher volatility in the natural gas markets on a longer-term basis.
Change in storage and transportation derivatives There was little price volatility in 2016 to benefit wholesale services’ portfolio of pipeline transportation and storage capacity assets throughout the country. Although we do not expect a high level of price volatility, we see the potential for market fundamentals indicating some level of increased volatility that would potentially benefit wholesale services’ portfolio of pipeline transportation capacity should this occur. The storage derivative gains for the three months ended March 31, 2016 are primarily due to a decline in natural gas prices applicable to the locations of our specific storage assets. Gains in our transportation and forward commodity derivative positions for the first three months of 2016 are the result primarily of narrowing transportation basis spreads associated with warmer-than-normal weather in the first quarter of 2016 and lower demand, which impacted forward prices at natural gas receipt and delivery points, primarily in the Northeast region. These gains are temporary and more than half is expected to be realized in 2016 and the balance thereafter with the physical flow of natural gas and utilization of the contracted transportation capacity at their lower rates.
Withdrawal schedule and physical transportation transactions The expected natural gas withdrawals from storage and expected offset to prior hedge losses/gains associated with the transportation portfolio of wholesale services are presented in the following table, along with the net operating revenues expected at the time of withdrawal from storage and the physical flow of

Glossary of Key Terms

natural gas between contracted transportation receipt and delivery points. Wholesale services’ expected net operating revenues exclude storage and transportation demand charges, as well as other variable fuel, withdrawal, receipt and delivery charges, but are net of the estimated impact of profit sharing under our asset management agreements. Further, the amounts that are realizable in future periods are based on the inventory withdrawal schedule, planned physical flow of natural gas between the transportation receipt and delivery points and forward natural gas prices at March 31, 2016. A portion of wholesale services’ storage inventory and transportation capacity is economically hedged with futures contracts, which results in the realization of substantially fixed net operating revenues, timing notwithstanding.

Midstream Operations
Our midstream operations segment’s primary activity is operating non-utility storage and pipeline facilities, including the development and operation of high-deliverability underground natural gas storage and pipeline assets. While this business can also generate additional revenue during times of peak market demand for natural gas storage services, certain of our storage services are covered under short-, medium- and long-term contracts at fixed market rates. For the three months ended March 31, 2016, midstream operations’ EBIT increased by $1 million compared to the same period during the prior year.
Other
Our "other" segment includes our investment in Triton, AGL Services Company and AGL Capital as well as various corporate operating expenses that we do not allocate to our reportable segments. For the three months ended March 31, 2016, such operating expenses included $3 million of merger-related expenses.
Liquidity and Capital Resources
Overview The acquisition of natural gas and pipeline capacity, payment of dividends and funding of working capital needs primarily related to our natural gas inventory are our most significant short-term financing requirements. The liquidity required to fund these short-term needs is generally provided by our operating activities, and any needs not met are primarily satisfied with short-term borrowings under our commercial paper programs, which are supported by the AGL Credit Facility and the Nicor Gas Credit Facility. For more information on the seasonality of our short-term borrowings, see "Short-term Debt" later in this section. The need for long-term capital is driven primarily by capital expenditures and maturities of long-term debt. Periodically, we raise funds supporting our long-term cash needs from the issuance of long-term debt or equity securities, subject to certain limitations. We regularly evaluate our funding strategy and profile to ensure that we have sufficient liquidity for our short-term and long-term needs in a cost-effective manner.
Our financing activities, including long-term and short-term debt and equity, are subject to customary approval or review by the state regulatory agencies in which we conduct business as well as the FERC. A substantial portion of our consolidated assets, earnings and cash flows is derived from the operation of our regulated utility subsidiaries, whose legal authority to pay dividends or make other distributions to us may be subject to regulation. By regulation, Nicor Gas is restricted, to the extent of its retained earnings balance, in the amount it can dividend or loan to affiliates and is not permitted to make money pool loans to affiliates. Additionally, Elizabethtown Gas is restricted by its dividend policy as established by the New Jersey BPU in the amount it can dividend to AGL Resources to the extent of 70% of its quarterly net income.
We believe the amounts available to us under our long-term debt and credit facilities as well as through the issuance of additional debt, combined with cash provided by operating activities, will continue to allow us to meet our needs for working capital, capital expenditures, anticipated debt redemptions, interest payments on debt obligations, dividend payments and other cash needs through the next several years.
The ability to satisfy our working capital requirements and our debt service obligations, or fund planned capital expenditures, substantially depends upon our future operating performance (which will be affected by prevailing economic conditions) and

financial, business and other factors, some of which we are unable to control. These factors include, among others, regulatory changes, the price of and demand for natural gas, and operational risks.
Our capitalization and financing strategy is intended to ensure that we are properly capitalized with the appropriate mix of debt and equity securities. This strategy includes active management of the percentage of total debt relative to total capitalization, as well as the term and interest rate profile of our debt securities and maintenance of an appropriate mix of debt with fixed and floating interest rates. Our variable-rate debt target is 20% to 45% of total debt. As of March 31, 2016, our variable-rate debt was 21% of our total debt, compared to 28% as of December 31, 2015 and 21% as of March 31, 2015. The decrease from December 31, 2015 was primarily due to decreased commercial paper borrowings resulting from customer collections on winter sales of natural gas and other seasonal working capital needs.
On February 1, 2016, $75 million of Nicor Gas first mortgage bonds matured and were repaid using the proceeds from commercial paper borrowings.
In January 2015, we executed $800 million in notional value of 10-year and 30-year fixed-rate forward-starting interest rate swaps to hedge potential interest rate volatility prior to our issuance of senior notes in the fourth quarter of 2015 and anticipated issuances of long-term debt in 2016. We designated the forward-starting interest rate swaps, which mature on the respective debt issuance dates, as cash flow hedges. We settled $200 million of these interest rate swaps on November 18, 2015. The remaining $600 million of interest rate swaps, which represent a fair value liability of $36 million as of March 31, 2016, are expected to be settled in 2016 as we issue long-term debt as planned. See Part I, Item 3, “Quantitative and Qualitative Disclosures About Market Risk,” under the caption “Interest Rate Risk” herein for additional information.
We entered into an agreement with Piedmont to purchase its remaining 15% interest in SouthStar for $160 million. This transaction is contingent upon the closing of the merger between Piedmont and Duke Energy Corporation, which is expected to occur in 2016.
Our objective remains to maintain a strong balance sheet and liquidity profile, solid investment grade ratings and annual dividend growth. Additionally, we will continue to evaluate our need to increase available liquidity based on our view of working capital requirements, including the impact of changes in natural gas prices, liquidity requirements established by rating agencies, acquisitions and other factors. Upon closing, if any, of the proposed merger with Southern Company, we do not expect to pay a prorated dividend. We have not yet determined the timing of our last quarterly dividend to existing public holders of our common stock, if any, declared prior to the potential closing of the proposed merger with Southern Company. See Item 1A, “Risk Factors,” in our 2015 Form 10-K for additional information on items that could impact our liquidity and capital resource requirements.
Capital Projects We continue to focus on capital discipline while moving forward with projects and initiatives that we expect will have current and future benefits to us and our customers, provide an appropriate return on invested capital and ensure the safety, reliability and integrity of our utility infrastructure. These capital projects update or expand our distribution systems to improve system reliability and meet operational flexibility and growth. Our anticipated expenditures for these programs in 2016 are discussed in “Liquidity and Capital Resources” under the caption "Cash Flow from Investing Activities" under Item 7 of our 2015 Form 10-K. For additional information on our capital projects, see Item 1 “Business” in our 2015 Form 10-K.
Short-Term Debt Our short-term debt table includes information relating to borrowings under our commercial paper programs and the current portion of our long-term debt. Our commercial paper borrowings are supported by the $1.3 billion AGL Credit Facility and $700 million Nicor Gas Credit Facility. The Nicor Gas Credit Facility can only be used for the working capital needs of Nicor Gas.

For the three months ended March 31, 2016.
The largest, minimum and daily average balances borrowed under our commercial paper programs are important when assessing the intra-period fluctuations of our short-term borrowings and potential liquidity risk. The fluctuations are due to our seasonal cash requirements to fund working capital needs, in particular the purchase of natural gas inventory, margin calls and collateral posting requirements. The largest and minimum balances outstanding for each debt instrument occurred at different times during the period. Therefore, the total balances are not indicative of actual borrowings on any one day during the period.
As the current portions of long-term debt mature throughout the remainder of 2016, we expect to refinance the maturing bonds with new issuances of long-term debt.
Increasing natural gas commodity prices can significantly impact our commercial paper borrowings. Based on current natural gas prices and our expected injection plan, a $1 NYMEX price increase could result in a $194 million change of working capital requirements during 2016. This range is sensitive to the timing of storage injections and withdrawals, collateral

requirements and our portfolio position. Based upon our total debt outstanding as of March 31, 2016, and our maximum 70% debt to total capitalization allowed under our financial covenants, we could potentially borrow an additional $1.1 billion of commercial paper under the AGL Credit Facility and an additional $347 million of commercial paper under the Nicor Gas Credit Facility. As a result, based on current natural gas prices and our expected purchases as we make natural gas storage injections in advance of the upcoming Heating Season, we believe that we have sufficient liquidity to cover our working capital needs for the upcoming injection season.
Credit Ratings Our borrowing costs and our ability to obtain adequate and cost-effective financing are directly impacted by our credit ratings and the availability of financial markets. Credit ratings are important to our counterparties when we engage in certain transactions, including over-the-counter derivatives. It is our long-term objective to maintain or improve our credit ratings in order to manage our existing financing costs and enhance our ability to raise additional capital on favorable terms.
Credit ratings and outlooks are opinions subject to ongoing review by the rating agencies and may periodically change. The rating agencies regularly review our performance and financial condition and reevaluate their ratings of our long-term debt and short-term borrowings, our corporate ratings and our ratings outlook. There is no guarantee that a rating will remain in effect for any given period of time or that a rating will not be lowered or withdrawn entirely by a rating agency if, in its judgment, circumstances so warrant. A credit rating is not a recommendation to buy, sell or hold securities, and each rating should be evaluated independently of other ratings.
Factors we consider important to assessing our credit ratings include our condensed consolidated balance sheets, leverage, capital spending, earnings, cash flow generation, available liquidity and overall business risks. We do not have any triggering events in our debt instruments that are tied to changes in our specified credit ratings or our stock price and have not entered into any agreements that would require us to issue equity based on credit ratings or other trigger events. A downgrade in our current ratings, particularly below investment grade, would increase our borrowing costs and could limit our access to the commercial paper market. In addition, we would likely be required to pay a higher interest rate in future financings, and our potential pool of investors and funding sources could decrease. The table below summarizes our credit ratings as of March 31, 2016, and reflects no change from December 31, 2015.

Cash Flow from Operating Activities Cash provided by operating activities decreased during the current period primarily due to lower usage of natural gas inventory during 2016 compared to 2015 as a result of warmer weather and the timing of recoveries of related gas costs and weather normalization adjustments from customers.
Cash Flow from Investing Activities The increased use of cash for our investing activities was the result of increased infrastructure investment, primarily relating to our infrastructure replacement programs as well as increased spending for other rate-based investments at distribution operations.
Cash Flow from Financing Activities The decreased use of cash for our financing activities was driven primarily by lower net repayments of debt during 2016 as a result of less cash from operations due to weather that was warmer in the first quarter of 2016 compared to the same period of 2015.

Contractual Obligations and Commitments We incur various contractual obligations and financial commitments in the normal course of business that are reasonably likely to have a material effect on liquidity or the availability of requirements for capital resources. Contractual obligations include future cash payments required under existing contractual arrangements, such as debt and lease agreements. These obligations may result from both general financing activities and from commercial arrangements that are directly supported by related revenue-producing activities. Contingent financial commitments represent obligations that become payable only if certain predefined events occur, such as financial guarantees, and include the nature of the guarantee and the maximum potential amount of future payments that could be required of us as the guarantor. For additional information, see Note 11 to our unaudited condensed consolidated financial statements under Part I, Item 1 herein.
Critical Accounting Policies and Estimates
The preparation of our financial statements in conformity with GAAP requires us to make estimates and judgments that affect the reported amounts in our unaudited condensed consolidated financial statements and accompanying notes. Those judgments and estimates have a significant effect on our financial statements, primarily due to the need to make estimates about the effects of matters that are inherently uncertain. Actual results could differ from those estimates. We frequently reevaluate our judgments and estimates that are based upon historical experience and various other assumptions that we believe to be reasonable under the circumstances.
Our critical accounting estimates often involve complex situations that require a high degree of judgment either in the application and interpretation of existing literature or in the development of estimates that impact our financial statements. There have been no significant changes to our critical accounting estimates from those disclosed in our Management’s Discussion and Analysis of Financial Condition and Results of Operations as filed on our 2015 Form 10-K. Our critical accounting estimates used in the preparation of our unaudited condensed consolidated financial statements include those related to our accounting for:
Rate-Regulated Subsidiaries;
Goodwill and Long-Lived Assets, including Intangible Assets;
Derivatives and Hedging Activities;
Contingencies;
Pension and Welfare Plans; and
Income Taxes.
Accounting Developments
See “Accounting Developments” in Note 3 to our unaudited condensed consolidated financial statements under Part I, Item 1 herein.
ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
We are exposed to risks associated with natural gas prices, interest rates and credit. Natural gas price risk results from changes in the fair value of natural gas. Interest rate risk is caused by fluctuations in interest rates related to our portfolio of debt instruments and equity that we issue to provide financing and liquidity for our business. Credit risk results from the extension of credit throughout all aspects of our business, but is particularly concentrated in wholesale services and at Atlanta Gas Light in distribution operations. We generally use derivative instruments to manage natural gas price and interest rate risks. Our use of derivative instruments is governed by a risk management policy and approved and monitored by our Risk Management Committee, which prohibits the use of derivatives for speculative purposes.
Our Risk Management Committee is responsible for establishing the overall risk management policies and monitoring compliance with, and adherence to, the terms within these policies, including approval and authorization levels and delegation of these levels. Our Risk Management Committee consists of members of senior management who monitor open natural gas price risks as well as other types of risk, corporate exposures, credit exposures and overall results of our risk management activities. It is chaired by our Chief Risk Officer, who is responsible for ensuring that appropriate reporting mechanisms exist for the Risk Management Committee to perform its monitoring functions. Our risk management activities and related accounting treatment for our derivative instruments are described in further detail in Note 6 of our unaudited condensed consolidated financial statements under Part I, Item 1 included herein.

VaR VaR is the maximum potential loss in portfolio value over a specified time period that is not expected to be exceeded within a given degree of probability. Our VaR may not be comparable to that of other companies due to differences in the factors used to calculate VaR. Our VaR is determined on a 95% confidence interval and a 1-day holding period, which means that 95% of the time, the risk of loss in a day from a portfolio of positions is expected to be less than or equal to the amount of VaR calculated. Our open exposure is managed in accordance with established policies that limit market risk and require daily reporting of potential financial exposure to senior management, including the Chief Risk Officer. Because we generally manage physical gas assets and economically protect our positions by hedging in the futures markets, our open exposure is generally mitigated. We employ daily risk testing, using both VaR and stress testing, to evaluate the risks of our open positions.
We actively monitor open commodity positions and the resulting VaR. We also continue to maintain a relatively matched book, where our total buy volume is close to our sell volume, with minimal open natural gas price risk. Based on a 95% confidence interval and employing a 1-day holding period, SouthStar’s portfolio of positions for the three months ended March 31, 2016 and 2015 was less than $0.1 million and wholesale services had the following VaRs.

Interest Rate Risk
Interest rate fluctuations expose our variable-rate debt to changes in interest expense and cash flows. Our policy is to manage interest expense using a combination of fixed-rate and variable-rate debt. Based on $877 million of variable-rate debt outstanding at March 31, 2016, a 100 basis point change in market interest rates would have resulted in an increase in pre-tax interest expense of $8 million on an annualized basis.
We utilize interest rate swaps to help us achieve our desired mix of variable to fixed-rate debt. Our variable-rate debt target generally ranges from 20% to 45% of total debt. We also use forward-starting interest rate swaps and interest rate lock agreements to lock in fixed interest rates on our forecasted issuances of debt. The objective of these hedges is to offset the variability of future payments associated with the interest rate on debt instruments we expect to issue. The gain or loss on the

interest rate swaps designated as cash flow hedges is generally deferred in accumulated OCI until settlement, at which point it is amortized to interest expense over the life of the related debt. For additional information, see Note 6 to our unaudited condensed consolidated financial statements included under Part I, Item 1 herein.
In January 2015, we executed $800 million in notional value of 10-year and 30-year fixed-rate, forward-starting interest rate swaps to hedge potential interest rate volatility prior to our senior note issuance in the fourth quarter of 2015 and our anticipated issuances in 2016. We have designated the forward-starting interest rate swaps, which are settled on the respective debt issuance dates, as cash flow hedges. We settled $200 million of these interest rate swaps on November 18, 2015, in conjunction with our November 2015 issuance of $250 million in senior notes. The remaining $600 million of interest rate swaps are expected to be settled in 2016 as we issue long-term debt as planned.
Credit Risk
Wholesale Services We have established credit policies to determine and monitor the creditworthiness of counterparties, as well as the quality of pledged collateral. We also utilize master netting agreements whenever possible to mitigate exposure to counterparty credit risk. When we are engaged in more than one outstanding derivative transaction with the same counterparty and we also have a legally enforceable netting agreement with that counterparty, the “net” mark-to-market exposure represents the netting of the positive and negative exposures with that counterparty and a reasonable measure of our credit risk. We also use other netting agreements with certain counterparties with whom we conduct significant transactions. Master netting agreements enable us to net certain assets and liabilities by counterparty. We also net across product lines and against cash collateral, provided the master netting and cash collateral agreements include such provisions.
We may require counterparties to pledge additional collateral when deemed necessary. We conduct credit evaluations and obtain appropriate internal approvals for a counterparty’s line of credit before any transaction with the counterparty is executed. In most cases, the counterparty must have an investment grade rating, which includes a minimum long-term debt rating of Baa3 from Moody’s and BBB- from S&P. Generally, we require credit enhancements by way of guaranty, cash deposit or letter of credit for transaction counterparties that do not have investment grade ratings.
We have a concentration of credit risk as measured by our 30-day receivable exposure plus forward exposure. As of March 31, 2016, our top 20 counterparties represented 54%, or $166 million, of our total counterparty exposure and had a weighted average S&P equivalent credit rating of A-, which is consistent with the prior year. The S&P equivalent credit rating is determined by a process of converting the lower of the S&P or Moody’s ratings to an internal rating ranging from 9 to 1, with 9 being equivalent to AAA/Aaa by S&P and Moody’s, respectively, and 1 being D or Default by S&P and Moody’s, respectively. A counterparty that does not have an external rating is assigned an internal rating based on the strength of the financial ratios of that counterparty. To arrive at the weighted average credit rating, each counterparty is assigned an internal ratio, which is multiplied by their credit exposure and summed for all counterparties. The sum is divided by the aggregate total counterparties’ exposures, and this numeric value is then converted to an S&P equivalent. The following table provides credit risk information related to our third-party natural gas contracts receivable and payable positions as of the periods presented.

We have certain trade and credit contracts that have explicit minimum credit rating requirements. These credit rating requirements typically give counterparties the right to suspend or terminate credit if our credit ratings are downgraded to non-investment grade status. Under such circumstances, we would need to post collateral to continue transacting business with some of our counterparties. If such collateral were not posted, our ability to continue transacting business with these counterparties would be impaired. If our credit ratings had been downgraded to non-investment grade status, the required amounts to satisfy potential collateral demands under such agreements with our counterparties would have totaled less than $1 million at March 31, 2016, which would not have had a material impact on our consolidated results of operations, cash flows or financial condition.
There have been no significant changes to our credit risk related to any of our segments other than wholesale services, as described in Item 7A ”Quantitative and Qualitative Disclosures about Market Risk” of our 2015 Form 10-K.

ITEM 4. CONTROLS AND PROCEDURES
(a) Evaluation of disclosure controls and procedures. Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of our disclosure controls and procedures, as such term is defined under Rule 13a-15(e) promulgated under the Securities Exchange Act of 1934, as amended (the Exchange Act), as of March 31, 2016, the end of the period covered by this report. No system of controls, no matter how well-designed and operated, can provide absolute assurance that the objectives of the system of controls are met, and no evaluation of controls can provide assurance that the system of controls has operated effectively in all cases. Our disclosure controls and procedures, however, are designed to provide reasonable assurance that the objectives of disclosure controls and procedures are met.
Based on this evaluation, our principal executive officer and our principal financial officer concluded that our disclosure controls and procedures were effective as of March 31, 2016. Our disclosure controls and procedures are designed to ensure that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods in SEC rules and forms and that such information is accumulated and communicated to our management, including our principal executive officer and our principal financial officer, as appropriate to allow timely decisions regarding required disclosure.
(b) Changes in Internal Control over Financial Reporting. There were no changes in our internal control over financial reporting that occurred during the quarter ended March 31, 2016 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
PART II - OTHER INFORMATION
Item 1. Legal Proceedings
The nature of our business ordinarily results in periodic regulatory proceedings before various state and federal authorities. In addition, we are party as both plaintiff and defendant to a number of lawsuits related to our business on an ongoing basis. Management believes that while the resolutions of these regulatory proceedings and litigation, whether individually or in the aggregate, could possibly be material to earnings in a particular quarter, they will not have a material adverse effect on our consolidated balance sheets or cash flows for the year. For more information regarding our regulatory proceedings and litigation, see Note 11 to our unaudited condensed consolidated financial statements under Part I, Item 1 herein.
Item 1A. Risk Factors
For information regarding our risk factors, see the factors discussed in Part I, Item 1A, “Risk Factors” in our 2015 Form 10-K. These risk factors could materially affect our business, financial condition or future results. There have been no significant changes to our risk factors included in Item 1A of our 2015 Form 10-K. The risks described in the referenced document are not the only risks facing the company. Additional risks and uncertainties not currently known to us or that we currently do not recognize as material may also materially adversely affect our business, financial condition or future results.
Item 2. Unregistered Sales of Equity Securities and Use of Proceeds
There were no purchases of our common stock by us or any affiliated purchasers during the first quarter of 2016, and no unregistered sales of equity securities were made during this period.
