AMERICAN TOWER CORPORATION AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—Unaudited

1.	Description of Business, Basis of Presentation and Accounting Policies

American Tower Corporation is, together with its subsidiaries (collectively, “ATC” or the “Company”), an independent developer, owner and operator of wireless and broadcast communications sites in the United States, Latin America and India. The Company’s primary business is the leasing of antenna space on multi-tenant communications sites to wireless service providers and radio and television broadcast companies. The Company also manages rooftop and tower sites for property owners, operates in-building and outdoor distributed antenna system (“DAS”) networks, and provides network development services that primarily support its rental and management operations and the addition of new tenants and equipment on its sites.

ATC is a holding company that conducts its operations through its directly and indirectly owned subsidiaries. ATC’s principal United States operating subsidiaries are American Towers, Inc. (“ATI”) and SpectraSite Communications, LLC (“SpectraSite”). ATC conducts its international operations through its subsidiary, American Tower International, Inc., which in turn conducts operations through its various international operating subsidiaries. The Company’s international operations consist primarily of its operations in Brazil, Chile, Colombia, India, Mexico and Peru.

The accompanying condensed consolidated financial statements have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The financial information included herein is unaudited; however, the Company believes that all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair presentation of the Company’s financial position and results of operations for such periods have been included. Results of interim periods may not be indicative of results for the full year. The Company considers events or transactions that occur after the balance sheet date but before the financial statements are issued as additional evidence for certain estimates or to identify matters that require additional disclosure. Subsequent events have been evaluated up to the date of issuance of these financial statements. These condensed consolidated financial statements and related notes should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2009.

Significant Accounting Policies and Use of Estimates—The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results may differ from those estimates, and such differences could be material to the accompanying condensed consolidated financial statements.

Concentrations of Credit Risk—The Company is subject to concentrations of credit risk related to its cash and cash equivalents, notes receivable, trade receivables, deferred rent asset and derivative instruments. The Company mitigates its risk with respect to cash and cash equivalents and derivative instruments by maintaining its deposits and contracts at high quality financial institutions and monitoring the credit ratings of those institutions.

The Company mitigates its concentrations of credit risk with respect to notes and trade receivables by actively monitoring the creditworthiness of its borrowers and customers. The Company derives the largest portion of its revenues, corresponding trade receivables and the related deferred rent asset from a small number of customers in the telecommunications industry, and as of September 30, 2010, approximately 60% of its revenues were derived from four customers in the United States, whose combined accounts receivable, net and deferred rent asset were $43.2 million and $313.9 million, respectively.

Grupo Iusacell, the Company’s largest international customer, which represented approximately 4% of the Company’s total revenues for the nine months ended September 30, 2010, has been engaged in a restructuring

AMERICAN TOWER CORPORATION AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—Unaudited—(Continued)

of its U.S. Dollar denominated debt since the first quarter of 2009. Effective April 1, 2010, the Company renegotiated its agreements with Grupo Iusacell to include, among other changes, the conversion of its accounts receivable, net, and associated value added tax, to a long-term interest bearing receivable to be repaid over five years. As of September 30, 2010, the long-term interest bearing receivable was $19.8 million and the related assets (which include financing lease commitments and a deferred rent asset that are primarily long-term in nature) were $47.6 million.

Foreign Currency —As a result of changes to the organizational structure of the Company’s subsidiaries in Latin America in 2010, the Company has determined that effective January 1, 2010, the functional currency of its foreign subsidiary in Brazil is the Brazilian Real. From that point forward, all assets and liabilities held by the subsidiary in Brazil are translated into U.S. Dollars at the exchange rate in effect at the end of the applicable reporting period. Revenues and expenses are translated at the average monthly exchange rates and the cumulative translation effect is included in stockholders’ equity. The change in functional currency from U.S. Dollars to Brazilian Real gave rise to an increase in the net value of certain non-monetary assets and liabilities. The aggregate impact on such assets and liabilities was $38.1 million with an offsetting increase in accumulated other comprehensive income (loss).

As a result of the renegotiation of the Company’s agreements with Grupo Iusacell, which included, among other changes, converting all of Grupo Iusacell’s contractual obligations to the Company from U.S. Dollars to Mexican Pesos, the Company has determined that effective April 1, 2010, the functional currency of certain of its foreign subsidiaries in Mexico is the Mexican Peso. From that point forward, all assets and liabilities held by those subsidiaries in Mexico are translated into U.S. Dollars at the exchange rate in effect at the end of the applicable reporting period. Revenues and expenses are translated at the average monthly exchange rates and the cumulative translation effect is included in stockholders’ equity. The change in functional currency from U.S. Dollars to Mexican Pesos gave rise to a decrease in the net value of certain non-monetary assets and liabilities. The aggregate impact on such assets and liabilities was $37.6 million with an offsetting decrease in accumulated other comprehensive income (loss).

Recently Adopted Accounting Standards—In January 2010, the Financial Accounting Standards Board (“FASB”) issued guidance clarifying existing disclosure requirements and adding disclosure requirements with respect to fair value measurements. This guidance was effective for the Company as of January 1, 2010 and had no impact on its condensed consolidated results of operations or financial position.

Accounting Standards Updates—In October 2009, the FASB issued new guidance which establishes accounting and reporting guidance for arrangements including multiple revenue-generating activities. This guidance requires companies to allocate the overall consideration to each deliverable under the arrangement using the estimated selling prices in the absence of vendor specific objective evidence or third-party evidence of selling price for deliverables. This guidance is effective for any contracts entered into, or materially modified by the Company after January 1, 2011, with early adoption available. The Company is evaluating the impact, if any, that this update will have on its condensed consolidated results of operations and financial position.

2.	Short-Term Investments and Available-For-Sale Securities

As of September 30, 2010, short-term investments and available-for-sale securities included Brazilian Treasury securities of $42.5 million, whose original maturities were in excess of three months, and $0.2 million of available-for-sale securities.

(1)	Acquired network location intangibles are amortized over the shorter of the term of the corresponding ground lease or 20 years, as the Company considers these intangibles to be directly related to the tower assets.

(2)	Deferred financing costs are amortized over the term of the respective debt instruments to which they relate. This amortization is included in interest expense, rather than in amortization expense.

(3)	Balances have been revised to reflect purchase accounting measurement period adjustments.

The Company amortizes these intangibles on a straight-line basis. As of September 30, 2010, the remaining weighted average amortization period of the Company’s intangible assets, excluding the TV Azteca Economic Rights detailed in note 4 to the Company’s consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2009, was approximately 11 years. Amortization of intangible assets for the three and nine months ended September 30, 2010 was approximately $39.1 million and $114.6 million (excluding amortization of deferred financing costs, which is included in interest expense), respectively. Amortization of intangible assets for the three and nine months ended September 30, 2009 was approximately $36.2 million and $104.2 million (excluding amortization of deferred financing costs, which is included in interest expense), respectively.

4.	Financing Transactions

Revolving Credit Facility and Term Loan—As of September 30, 2010, the Company had $400.0 million outstanding under its $1.25 billion senior unsecured revolving credit facility (“Revolving Credit Facility”) and

AMERICAN TOWER CORPORATION AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—Unaudited—(Continued)

had approximately $3.1 million of undrawn letters of credit outstanding. On November 4, 2010, the Company entered into a definitive agreement to acquire towers in South Africa (see note 13), which included a letter of credit of $30.0 million. In March 2008, the Company increased its borrowing capacity under the Revolving Credit Facility by adding $325.0 million of term loan commitments (“Term Loan”). As of September 30, 2010, the Term Loan was fully drawn. The Company continues to maintain the ability to draw down and repay amounts under the Revolving Credit Facility in the ordinary course.

XCEL Credit Facility—At the time of the Company’s acquisition of XCEL Telecom Private Limited (“XCEL”) on May 27, 2009, a 4.8 billion Indian Rupee-denominated credit facility (“XCEL Credit Facility”) was in place, of which 3.4 billion Indian Rupees (approximately $77.3 million) was outstanding. In April 2010, the Company repaid all of the outstanding indebtedness incurred under the XCEL Credit Facility and terminated the XCEL Credit Facility upon repayment.

5.05% Senior Notes Offering—On August 16, 2010, the Company completed a registered public offering of $700.0 million aggregate principal amount of its 5.05% senior notes due 2020 (“5.05% Notes”). The net proceeds to the Company from the offering were approximately $693.6 million, after deducting commissions and expenses. The Company used $575.0 million of the net proceeds to repay certain of its outstanding indebtedness incurred under its Revolving Credit Facility, which, along with cash on hand, was or will be used to finance the acquisition of Essar Telecom Infrastructure Private Limited (“ETIPL”) and other recent and potential acquisitions with the remainder used for general corporate purposes.

The 5.05% Notes mature on September 1, 2020, and interest is payable semi-annually in arrears on March 1 and September 1 of each year, commencing on March 1, 2011. The Company may redeem the 5.05% Notes at any time at a redemption price equal to 100% of the principal amount, plus a make-whole premium, together with accrued interest to the redemption date. Interest on the notes will accrue from August 16, 2010 and will be computed on the basis of a 360-day year comprised of twelve 30-day months.

If the Company undergoes a change of control, as defined in the prospectus supplement to the prospectus dated May 13, 2010, and ratings decline (in the event that on or within 90 days after an announcement of a change of control, both of its current investment grade credit ratings cease to be investment grade), the Company will be required to offer to repurchase all of the 5.05% Notes at a purchase price equal to 101% of the principal amount, plus accrued and unpaid interest (including additional interest, if any) up to but not including the repurchase date. The 5.05% Notes rank equally with all of the Company’s other senior unsecured debt and are structurally subordinated to all existing and future indebtedness and other obligations of its subsidiaries. The indenture contains certain covenants that restrict the Company’s ability to merge, consolidate or sell assets and its subsidiaries’ abilities to incur liens. These covenants are subject to a number of exceptions, including that the Company and its subsidiaries may incur certain liens on assets, mortgages or other liens securing indebtedness, if the aggregate amount of such liens does not exceed 3.5x Adjusted EBITDA, as defined in the indenture.

ETIPL Debt—At the time of the Company’s acquisition of ETIPL on August 6, 2010, ETIPL had in place term loans principally denominated in Indian Rupees in an amount equal to approximately 6.5 billion Indian Rupees, and a working capital loan in an amount equal to approximately 297.5 million Indian Rupees (“ETIPL Debt”). As of September 30, 2010, 6.5 billion Indian Rupees (approximately $144.6 million) was outstanding. As of October 20, 2010, the Company repaid all of the outstanding ETIPL Debt.

Colombian Short-Term Credit Facility—In connection with the purchase of the exclusive rights for 225 towers from Telefónica S.A.’s Colombian subsidiary, Colombia Telecomunicaciones S.A. E.S.P. (“Coltel”), the Company entered into a 72.8 billion Colombian Peso-denominated revolving credit facility on September 3,

AMERICAN TOWER CORPORATION AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—Unaudited—(Continued)

2010. The credit facility matures on March 2, 2011 and accrues interest at a rate of 6.50% that is payable upon maturity.

As of September 30, 2010, the Company had 58.0 billion Colombian Pesos (approximately $32.2 million) outstanding under this credit facility. On October 6, 2010, the Company borrowed the remaining 14.8 billion Colombian Pesos available under the credit facility in connection with the acquisition of an additional 160 towers and use rights in Colombia.

Redemption of ATI 7.25% Senior Subordinated Notes—During the nine months ended September 30, 2010, ATI issued a notice for the redemption of the remaining $0.3 million aggregate principal amount of its 7.25% senior subordinated notes due 2011 (“ATI 7.25% Notes”). In accordance with the redemption provisions and the indenture for the ATI 7.25% Notes, the remaining ATI 7.25% Notes were redeemed at a price equal to 100.00% of the principal amount, plus accrued and unpaid interest up to, but excluding, September 23, 2010, for an aggregate purchase price of $0.3 million. Upon completion of this redemption, none of the ATI 7.25% Notes remained outstanding.

Stock Repurchase Program—During the nine months ended September 30, 2010, the Company repurchased an aggregate of 7.8 million shares of its Class A common stock (“Common Stock”) for an aggregate of $346.2 million, including commissions and fees, pursuant to its $1.5 billion stock repurchase program approved by the Company’s Board of Directors in February 2008 (“2008 Buyback”). Between October 1, 2010 and October 22, 2010, the Company repurchased a total of 551,690 shares of its Common Stock for an aggregate of $28.0 million, including commissions and fees. As of October 22, 2010, the Company had repurchased a total of 28.9 million shares of Common Stock for an aggregate of $1.1 billion, including commissions and fees, pursuant to the 2008 Buyback, and the remaining authorized amount for stock repurchases under the 2008 Buyback was $0.4 million.

Under the 2008 Buyback, the Company is authorized to purchase shares from time to time through open market purchases or privately negotiated transactions at prevailing prices in accordance with securities laws and other legal requirements, and subject to market conditions and other factors. To facilitate repurchases, the Company purchases its Common Stock pursuant to trading plans under Rule 10b5-1 of the Securities Exchange Act of 1934, as amended, which allows the Company to repurchase shares during periods when it otherwise might be prevented from doing so under insider trading laws or because of self-imposed trading blackout periods. In the near term, the Company expects to fund any further repurchases of its Common Stock through a combination of cash on hand, cash generated by operations and borrowings under its Revolving Credit Facility. Purchases under the 2008 Buyback are subject to the Company having available cash to fund repurchases.

5.	Derivative Financial Instruments

The Company is exposed to certain risks related to its ongoing business operations. The primary risk managed through the use of derivative instruments is interest rate risk. The Company enters into interest rate protection agreements to manage exposure on the variable rate debt under its credit facilities and to manage variability in cash flows relating to forecasted interest payments. Under these agreements, the Company is exposed to credit risk to the extent that a counterparty fails to meet the terms of a contract. The Company’s credit risk exposure is limited to the current value of the contract at the time the counterparty fails to perform. The Company believes its contracts as of September 30, 2010 are with creditworthy institutions.

If a derivative is designated as a cash flow hedge, the effective portions of changes in the fair value of the derivative are recorded in accumulated other comprehensive income (loss) and are recognized in the results of operations when the hedged item affects earnings. Ineffective portions of changes in the fair value of cash flow

AMERICAN TOWER CORPORATION AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—Unaudited—(Continued)

hedges are recognized immediately in the results of operations. For derivative instruments not designated as hedging instruments, changes in fair value are recognized in the results of operations in the period in which the change occurs.

As of September 30, 2010, the Company held thirteen interest rate swap agreements, all of which have been designated as cash flow hedges, and which have an aggregate notional amount of $625.0 million, interest rates ranging from 2.86% to 4.08% and expiration dates through March 2011. The Company utilizes these interest rate swap agreements to manage its exposure to variability in cash flows relating to forecasted interest payments under its Revolving Credit Facility and Term Loan. As of September 30, 2010 and December 31, 2009, the carrying amounts of the Company’s derivative financial instruments, along with the estimated fair values of the related liabilities were as follows (in thousands):


As of September 30, 2010	Balance Sheet Location	Notional Amount		Carrying Amount and Fair Value
Liabilities:
Interest rate swap agreements	Other long-term liabilities	$	625,000	$	7,910

As of December 31, 2009	Balance Sheet Location	Notional Amount		Carrying Amount and Fair Value
Liabilities:
Interest rate swap agreements	Other long-term liabilities	$	625,000	$	18,852

During the nine months ended September 30, 2010 and 2009, the interest rate swap agreements held by the Company had the following impact on other comprehensive income (“OCI”) included in the condensed consolidated balance sheet and in the condensed consolidated statement of operations (in thousands):

6.	Fair Value Measurements

The Company determines the fair market values of its financial instruments based on the fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Below are the three levels of inputs that may be used to measure fair value:


Level 1		Quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.

Level 2		Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3		Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Items Measured at Fair Value on a Recurring Basis—The fair value of the Company’s financial assets and liabilities that are required to be measured on a recurring basis at fair value is as follows:


	September 30, 2010
	Fair Value Measurements Using					Assets/Liabilities at Fair Value
	Level 1		Level 2		Level 3	Assets/Liabilities at Fair Value
	(in thousands)
Assets:
Short-term investments and available-for-sale securities (1)	$	42,720				$	42,720
Liabilities:
Interest rate swap agreements (2)			$	7,910		$	7,910

	December 31, 2009
	Fair Value Measurements Using					Assets/Liabilities at Fair Value

Short-term investments and available-for-sale securities (1)	$	9,776				$	9,776
Liabilities:
Interest rate swap agreements (2)			$	18,852		$	18,852

(1)	Consists of available-for-sale securities traded on active markets as well as certain Brazilian Treasury securities that are highly liquid and actively traded in over-the-counter markets.

(2)	Consists of interest rate swap agreements based on the London Interbank Offered Rate whose value is determined using a pricing model with inputs that are observable in the market or can be derived principally from, or corroborated by, observable market data.

The fair value of the Company’s interest rate swap agreements recorded as liabilities is included in other long-term liabilities in the accompanying condensed consolidated balance sheet as of September 30, 2010. Fair valuations of the Company’s interest rate swap agreements reflect the value of the instrument including the values associated with counterparty risk and the Company’s own credit standing. The Company includes in the valuation of the derivative instrument the value of the net credit differential between the counterparties to the derivative contract.

AMERICAN TOWER CORPORATION AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—Unaudited—(Continued)

Items Measured at Fair Value on a Nonrecurring Basis—The Company’s notes receivable and other long-term assets, long-lived assets, intangibles and goodwill are measured at fair value on a nonrecurring basis. During the nine months ended September 30, 2010, the Company did not record any significant changes to the fair value of these assets as a result of an impairment, using Level 3 inputs, on a nonrecurring basis.

Fair Value of Financial Instruments—The carrying value of the Company’s financial instruments, with the exception of long-term obligations, including current portion, reasonably approximate the related fair values as of September 30, 2010 and December 31, 2009. The Company’s estimates of fair value of its long-term obligations, including current portion, are based primarily upon reported market values. As of September 30, 2010, the carrying value and fair value of long-term obligations, including current portion, were $4.8 billion and $5.1 billion, respectively. As of December 31, 2009, the carrying value and fair value of long-term obligations, including current portion, were $4.2 billion and $4.3 billion, respectively.

7.	Income Taxes

The Company provides for income taxes at the end of each interim period based on the estimated effective tax rate for the full fiscal year. Cumulative adjustments to the Company’s estimate are recorded in the interim period in which a change in the estimated annual effective rate is determined.

As of September 30, 2010, the Company had unrecognized tax benefits of $79.0 million. If recognized, approximately $37.5 million would impact discontinued operations. The total amount that would affect continuing operations, and hence the effective tax rate, would be $33.0 million, net of deferred tax assets of $8.5 million. The Company expects the unrecognized tax benefits to change over the next 12 months if certain tax matters ultimately settle with the applicable taxing jurisdiction during this timeframe, as described in note 11 to the Company’s consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2009. The impact of the amount of such changes to previously recorded uncertain tax positions could range from zero to $2.5 million. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in thousands):


Balance at January 1, 2010	$	87,975
Additions based on tax positions related to the current year		10,270
Additions for tax positions of prior years		11,109
Reductions for tax positions of prior years		(30,855	)
Foreign currency		596
Reduction as a result of the lapse of statute limitations		(53	)

Balance at September 30, 2010	$	79,042

The Company recorded penalties and tax-related interest expense during the three and nine months ended September 30, 2010 of $0.8 million and $2.2 million, respectively. As of September 30, 2010 and December 31, 2009, the total amount of accrued income tax-related interest and penalties included in other long-term liabilities in the condensed consolidated balance sheets was $18.0 million and $15.2 million, respectively.

In addition to movements in the unrecognized tax benefit, there were two separate events during the nine months ended September 30, 2010, that favorably impacted the tax provision:

(i) In an effort to efficiently fund Latin American operations, during the first quarter of 2010, the Company reorganized an existing financing entity, which resulted in a reversal of $32.6 million of accrued income tax liabilities which was recognized in the condensed consolidated statements of operations.

AMERICAN TOWER CORPORATION AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—Unaudited—(Continued)

(ii) During the second quarter of 2010, the Company performed additional analysis of its net operating losses, resulting in recognition of $26.3 million of previously unrecognized net operating losses in the condensed consolidated statements of operations.

8.	Stock-Based Compensation

The Company recognized stock-based compensation expense during the three and nine months ended September 30, 2010 of approximately $13.4 million and $40.1 million, respectively, and stock-based compensation expense during the three and nine months ended September 30, 2009 of approximately $13.0 million and $50.1 million, respectively. Stock-based compensation expense for the nine months ended September 30, 2009 includes $6.6 million related to the modification of the vesting and exercise terms for a certain employee’s equity awards. The Company did not capitalize any stock-based compensation during the nine months ended September 30, 2010 and 2009.

Stock Options—During the nine months ended September 30, 2010, the Company granted stock options to purchase 1.1 million shares of its Common Stock pursuant to its 2007 Equity Incentive Plan (“2007 Plan”).

The following table summarizes the Company’s option activity for the nine months ended September 30, 2010:


	Number of Options
Outstanding as of January 1, 2010		11,434,178
Granted		1,085,178
Exercised		(3,760,809	)
Forfeited		(281,948	)
Expired		(34,045	)

Outstanding as of September 30, 2010		8,442,554

The Company estimates the fair value of each option grant on the date of grant using the Black-Scholes pricing model. The following assumptions were used to determine the grant date fair value for options granted during the nine months ended September 30, 2010:


Range of risk-free interest rate		1.41% - 2.39%
Weighted average risk-free interest rate		2.37%
Expected life of option grants		4.6
Range of expected volatility of underlying stock price		37.11% - 37.48%
Weighted average expected volatility of underlying stock price		37.14%
Expected annual dividends		N/A

The weighted average grant date fair value per share during the nine months ended September 30, 2010 was $14.98. As of September 30, 2010, total unrecognized compensation expense related to unvested stock options was $33.6 million, and is expected to be recognized over a weighted average period of approximately two years.

Restricted Stock Units—During the nine months ended September 30, 2010, the Company granted restricted stock units with respect to 0.9 million shares of its Common Stock pursuant to the 2007 Plan.

AMERICAN TOWER CORPORATION AND SUBSIDIARIES

The following table summarizes the Company’s restricted stock unit activity during the nine months ended September 30, 2010:


	Number of Units
Outstanding as of January 1, 2010		2,026,032
Granted		907,088
Vested		(563,122	)
Forfeited		(136,830	)

Outstanding as of September 30, 2010		2,233,168

As of September 30, 2010, total unrecognized compensation expense related to unvested restricted stock units was $63.1 million, and is expected to be recognized over a weighted average period of approximately three years.

Employee Stock Purchase Plan—The Company maintains an employee stock purchase plan (“ESPP”) for all eligible employees as described in note 12 to the Company’s Annual Report on Form 10-K for the year ended December 31, 2009. The offering periods run from June 1 through November 30 and from December 1 through May 31 of each year. During the nine months ended September 30, 2010, employees purchased 38,542 shares under the ESPP. Using the Black-Scholes pricing model, the Company determined that the fair value of the shares purchased was $9.51.

Key assumptions used to apply the Black-Scholes pricing model for shares purchased through the ESPP during the nine months ended September 30, 2010 are as follows:


Approximate risk-free interest rate		0.22%
Expected life of shares		6 months
Expected volatility of underlying stock price		35.27%
Expected annual dividends		N/A

9.	Earnings per Common Share

Basic income from continuing operations per common share represents income from continuing operations attributable to American Tower Corporation divided by the weighted average number of common shares outstanding during the period. Diluted income from continuing operations per common share represents income from continuing operations attributable to American Tower Corporation divided by the weighted average number of common shares outstanding during the period and any dilutive common share equivalents, including shares issuable upon exercise of stock options, share based awards and warrants as determined under the treasury stock method and upon conversion of the Company’s convertible notes, as determined under the if-converted method.

Commitments and Contingencies

Litigation—The Company periodically becomes involved in various claims and lawsuits that are incidental to its business. In the opinion of Company management, after consultation with counsel, other than the legal proceedings discussed below, there are no matters currently pending that would, in the event of an adverse outcome, materially impact the Company’s consolidated financial position, results of operations or liquidity.

Legal and Governmental Proceedings Related to Review of Stock Option Granting Practices and Related Accounting—During the year ended December 31, 2006, the Company received a letter of informal inquiry from the SEC Division of Enforcement, a subpoena from the United States Attorney’s Office for the Eastern District of New York, and an Information Document Request from the Internal Revenue Service (“IRS”), each requesting documents and other information related to Company stock option grants and stock option practices. In addition, in August 2007, the Company received a request for information from the Department of Labor (“DOL”) with respect to the Company’s retirement savings plan, including documents related to Company stock option grants and the Company’s historical stock option administrative practices. The Company has also become aware that a

AMERICAN TOWER CORPORATION AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—Unaudited—(Continued)

former officer of the Company received a “Wells” notice from the SEC, which affords such individual the opportunity to make a submission to the SEC with respect to contemplated civil enforcement recommendations against such individual for certain violations of the federal securities laws. In September 2008, the DOL concluded its review and advised the Company that no action would be taken. The reviews being conducted by the SEC, the U.S. Attorney’s Office and the IRS remain open, and the Company has cooperated on these matters.

Mexico Litigation—One of the Company’s subsidiaries, SpectraSite Communications, Inc. (“SCI”), is involved in a lawsuit brought in Mexico against a former Mexican subsidiary of SCI (the subsidiary of SCI was sold in 2002, prior to the Company’s merger with SCI’s parent in 2005). The lawsuit concerns a terminated tower construction contract and related agreements with a wireless carrier in Mexico. The primary issue for the Company is whether SCI can be found liable to the Mexican carrier. The trial and lower appellate courts initially found that SCI had no such liability in part because Mexican courts do not have full jurisdiction over SCI. Following several decisions by Mexican appellate courts, including the Supreme Court of Mexico, and related appeals by both parties, the current status of this case is that in September 2010, an intermediate appellate court issued a new decision reimposing liability on SCI. The damages assessed by the intermediate appellate court are approximately $6.7 million. On October 14, 2010, the Company filed a new constitutional appeal to again dispute the intermediate appellate court’s recent decision. As a result, at this stage of the proceeding, the Company is unable to determine whether the liability imposed on SCI by the September 2010 decision will survive or to estimate its share, if any, of that potential liability if the decision survives the pending appeal.

XCEL Litigation—On June 3, 2010, Horse-Shoe Capital (“Horse-Shoe”), a company formed under the laws of the Republic of Mauritius, filed a complaint in the Supreme Court of the State of New York, New York County, with respect to Horse-Shoe’s sale of XCEL to American Tower Mauritius (“AT Mauritius”), the Company’s wholly-owned subsidiary formed under the laws of the Republic of Mauritius. The complaint names AT Mauritius, ATI and the Company as defendants, and the dispute concerns the timing and amount of distributions to be made by AT Mauritius to Horse-Shoe from a $7.5 million holdback escrow account and a $15.7 million tax escrow account, each established by the transaction agreements at closing. The complaint seeks release of the entire holdback escrow account, plus an additional $2.8 million, as well as the release of approximately $12.0 million of the tax escrow account. The complaint also seeks punitive damages in excess of $69 million. The Company filed an answer to the complaint in August 2010, disputing both the amounts alleged to be owed under the escrow agreements as well as the timing of the escrow distributions. The Company also asserted in its answer that the demand for punitive damages is meritless. The parties have filed cross-motions for summary judgment concerning the release of the tax escrow account. Those motions and the other claims remain pending.

AT&T Transaction—The Company has an agreement with SBC Communications Inc., a predecessor entity to AT&T Inc. (“AT&T”), for the lease or sublease of approximately 2,500 towers from AT&T between December 2000 and August 2004. All of the towers are part of the Company’s securitization transaction. The average term of the lease or sublease for all sites at the inception of the agreement was approximately 27 years, assuming renewals or extensions of the underlying ground leases for the sites. The Company has the option to purchase the sites subject to the applicable lease or sublease upon its expiration. Each tower is assigned to an annual tranche, ranging from 2013 to 2032, which represents the outside expiration date for the sublease rights to that tower. The purchase price for each site is a fixed amount stated in the sublease for that site plus the fair market value of certain alterations made to the related tower by AT&T. The aggregate purchase option price for the towers leased and subleased was approximately $442.9 million as of September 30, 2010, and will accrete at a rate of 10% per year to the applicable expiration of the lease or sublease of a site. For all such sites purchased by the Company prior to June 30, 2020, AT&T will continue to lease the reserved space at the then-current monthly fee which shall escalate in accordance with the standard master lease agreement until June 30, 2020.

Thereafter, AT&T shall have the right to renew such lease for up to four successive five-year terms. For all such sites purchased by the Company subsequent to June 30, 2020, AT&T has the right to continue to lease the reserved space for successive one year terms at a rent equal to the lesser of the agreed upon market rate and the then current monthly fee, which is subject to an annual increase based on changes in the Consumer Price Index.

ALLTEL Transaction—In December 2000, the Company entered into an agreement with ALLTEL (which completed its merger with Verizon Wireless in January 2009) to acquire towers from ALLTEL through a 15-year sublease agreement. Pursuant to the agreement with ALLTEL, as amended, the Company acquired rights to a total of approximately 1,800 towers in tranches between April 2001 and March 2002. The Company has the option to purchase each tower at the expiration of the applicable sublease, which will occur in tranches between April 2016 and March 2017 based on the original closing date for such tranche of towers. The purchase price per tower as of the original closing date was $27,500 and will accrete at a rate of 3% per annum through the expiration of the applicable sublease. The aggregate purchase option price for the subleased towers was approximately $64.7 million as of September 30, 2010. At ALLTEL’s option, at the expiration of the sublease, the purchase price would be payable in cash or with 769 shares of the Company’s Common Stock per tower.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—Unaudited—(Continued)

The accounting policies applied in compiling segment information below are similar to those described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2009. In evaluating financial performance, management focuses on segment gross margin and segment operating profit. The Company defines segment gross margin as segment revenue less segment operating expenses excluding depreciation, amortization and accretion; selling, general, administrative and development expense; and other operating expenses. The Company defines segment operating profit as segment gross margin less selling, general, administrative and development expense attributable to the segment, excluding stock-based compensation expense and corporate expenses. For reporting purposes, the rental and management segment operating profit and segment gross margin also include interest income, TV Azteca, net. These measures of segment gross margin and segment operating profit are also before interest income, interest expense, loss on retirement of long-term obligations, other income (expense), net income attributable to noncontrolling interest, income (loss) on equity method investments, income taxes and discontinued operations.

The Company’s reportable segments are strategic business units that offer different services. They are managed separately because each segment requires different resources, skill sets and marketing strategies. Summarized financial information concerning the Company’s reportable segments for the three and nine months ended September 30, 2010 and 2009 is shown in the tables below. The Other column below represents amounts excluded from specific segments, such as stock-based compensation expense and corporate expenses included in selling, general, administrative and development expense; other operating expense; interest income; interest expense; loss on retirement of long-term obligations; and other income (expense), as well as reconciles segment operating profit to income (loss) before income taxes, noncontrolling interest and income (loss) on equity method investments.

ITEM 2.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This Quarterly Report on Form 10-Q contains forward-looking statements relating to our goals, beliefs, plans or current expectations and other statements that are not of historical facts. For example, when we use words such as “project,” “believe,” “anticipate,” “expect,” “forecast,” “estimate,” “intend,” “should,” “would,” “could” or “may,” or other words that convey uncertainty of future events or outcomes, we are making forward-looking statements. Certain important factors may cause actual results to differ materially from those indicated by our forward-looking statements, including those set forth under the caption “Risk Factors” in Part II, Item 1A. of this Quarterly Report on Form 10-Q. Forward-looking statements represent management’s current expectations and are inherently uncertain. We do not undertake any obligation to update forward-looking statements made by us.

The discussion and analysis of our financial condition and results of operations that follow are based upon our condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). The preparation of our financial statements requires us to make estimates and judgments that affect the reported amounts of assets and liabilities, revenues and expenses, and the related disclosure of contingent assets and liabilities at the date of our financial statements. Actual results may differ significantly from these estimates under different assumptions or conditions. This discussion should be read in conjunction with our condensed consolidated financial statements herein and the accompanying notes thereto, information set forth under the caption “Critical Accounting Policies and Estimates” beginning on page 45 of our Annual Report on Form 10-K for the year ended December 31, 2009, in particular, the information set forth therein under Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Overview

We are a leading wireless and broadcast communications infrastructure company that develops, owns, and operates communications sites, including wireless communications towers, broadcast communications towers and distributed antenna system (“DAS”) networks. Our portfolio of wireless and broadcast towers consists of towers that we own and towers that we operate pursuant to long-term lease arrangements, including, as of September 30, 2010, approximately 20,500 towers in the United States and approximately 12,600 towers internationally. Our portfolio also includes approximately 200 in-building DAS networks that we operate in malls, casinos and other in-building applications in the United States and Mexico and three outdoor DAS networks in the United States. In addition to the communications sites in our portfolio, we manage rooftop and tower sites for property owners in the United States, Mexico and Brazil. Our primary business is leasing antenna space on multi-tenant communications sites to wireless service providers and radio and television broadcast companies. This segment of our business, which we refer to as our rental and management segment, accounted for approximately 97% of our total revenues for the three and nine months ended September 30, 2010.

In the section that follows, we provide information regarding management’s expectations of long-term drivers of demand for our communications sites, as well as our current quarter results of operations, financial position, and sources and uses of liquidity. In addition, we highlight key trends, which management believes provides valuable insight into operating and financial resource allocation decisions for the Company.

Revenue Growth. The primary factors affecting the consistent incremental growth in our revenues and cash flows for our rental and management segment are:

•

Recurring revenues from tenant leases generated from sites which existed in our portfolio as of the beginning of the prior year period (“legacy sites”);

•

Contractual tenant lease escalations, net of cancellations;

•

New revenue generated from leasing additional space on our legacy sites; and

•

New revenue generated from new sites acquired or constructed since the beginning of the prior year period (“new sites”).

We continue to believe that our site leasing revenue is likely to increase due to the growing use of wireless communications services and our ability to meet that demand by adding new tenants and new equipment for existing tenants on our legacy sites, which increases the utilization and profitability of our sites. In addition, we believe the majority of our site leasing activity will continue to come from customers providing wireless broadband services. Our legacy site portfolio and our established customer base provide us with a diverse source of new business opportunities, which has historically resulted in consistent and predictable revenue growth. In addition, we intend to supplement the growth on our legacy sites by selectively developing or acquiring new sites in our existing and new markets where we can achieve our return on investment criteria.

As we continue to focus on growing our rental and management business, we anticipate that our network development services revenue will continue to represent a small percentage of our total revenues. Through our network development services segment, we offer tower-related services, including site acquisition, zoning and permitting services and structural analysis services, which directly support our site leasing business and the addition of new tenants and equipment on our sites.

Our continuing operations are reported in two segments, rental and management and network development services. Management focuses on segment gross margin and segment operating profit as a means to measure operating performance in these business segments. We define segment gross margin as segment revenue less segment operating expenses excluding depreciation, amortization and accretion; selling, general, administrative and development expense; and other operating expenses. We define segment operating profit as segment gross margin less selling, general, administrative and development expense attributable to the segment, excluding stock-based compensation expense and corporate expenses. Segment gross margin and segment operating profit for the rental and management segment also include interest income, TV Azteca, net (see note 12 to our condensed consolidated financial statements included herein). These measures of segment gross margin and segment operating profit are also before interest income, interest expense, loss on retirement of long-term obligations, other income (expense), net income attributable to noncontrolling interest, income on equity method investments, income taxes and discontinued operations.

In accordance with our ability to utilize our federal tax net operating losses (“NOLs”), we are actively considering a conversion to a real estate investment trust for federal income tax purposes, although there is no certainty that we will do so.

Total Revenues

Total revenues for the three months ended September 30, 2010 were $513.3 million, an increase of $69.2 million from the three months ended September 30, 2009. This increase was attributable to a $69.3 million increase in rental and management revenue, partially offset by a decrease of $0.1 million in network development services revenue.

Rental and Management Revenue

Rental and management revenue for the three months ended September 30, 2010 was $499.8 million, an increase of $69.3 million from the three months ended September 30, 2009. Legacy sites contributed $38.7 million of the increase, which was primarily attributable to incremental revenue generated from adding new tenants to those sites, existing tenants adding more equipment to those sites, contractual tenant lease escalations

and the positive impact of foreign currency exchange rate fluctuations and straight-line revenue recognition, partially offset by tenant lease cancellations, a $6.7 million one-time revenue related to a termination agreement from the prior year period and a reduction in revenue recognized under a take or pay agreement. Approximately $30.6 million of the increase resulted from the 6,213 new sites that we acquired and 1,304 new sites that we constructed since July 1, 2009. The increase in straight-line revenue was primarily the result of our successful completion of customer contract extensions in the United States and a master lease renegotiation with one of our large U.S. customers.

Network Development Services Revenue

Network development services revenue for the three months ended September 30, 2010 was $13.5 million, a decrease of $0.1 million from the three months ended September 30, 2009. This decrease was primarily attributable to a decrease in the revenues generated from our site acquisition, zoning and permitting services.

Total Operating Expenses

Total operating expenses for the three months ended September 30, 2010 were $300.0 million, an increase of $34.9 million from the three months ended September 30, 2009. The increase was primarily attributable to an increase in expenses within our rental and management segment of $14.3 million, an increase in depreciation, amortization and accretion expenses of $9.8 million, an increase in selling, general, administrative and development expense of $9.4 million, an increase in other operating expenses of $1.3 million and an increase in expenses within our network development services segment of $0.1 million.

Rental and management expense for the three months ended September 30, 2010 was $115.4 million, an increase of $14.3 million from the three months ended September 30, 2009. Legacy sites contributed $0.7 million of the increase, which was primarily attributable to contractual ground lease escalations, inflationary cost increases and the unfavorable impact of foreign currency exchange rate fluctuations on expenses, partially offset by cost decreases in certain components of our tower portfolio, including property taxes. Approximately $13.6 million of the increase resulted from the 7,517 new sites that we acquired or constructed since July 1, 2009.

Rental and management segment gross margin for the three months ended September 30, 2010 was $388.0 million, an increase of $55.0 million from the three months ended September 30, 2009. The increase primarily resulted from the increase of $69.3 million in rental and management revenue, partially offset by the $14.3 million increase in rental and management expense described above.

Rental and management segment operating profit for the three months ended September 30, 2010 was $360.7 million, an increase of $50.0 million from the three months ended September 30, 2009. This increase was comprised of the $55.0 million increase in rental and management segment gross margin described above, partially offset by an increase of $5.1 million in selling, general, administrative and development expenses related to our rental and management segment, largely due to increased costs from the expansion of our international operations.

Network Development Services Expense/Segment Gross Margin/Segment Operating Profit

Network development services expense for the three months ended September 30, 2010 was $7.6 million, an increase of $0.1 million from the three months ended September 30, 2009. This increase was primarily attributable to an increase in the expenses generated from our site acquisition, zoning and permitting services.

Network development services segment gross margin for the three months ended September 30, 2010 was $5.9 million, a decrease of $0.2 million from the three months ended September 30, 2009. The decrease primarily

resulted from the decrease of $0.1 million in network development services revenue and an increase in the expenses generated from our site acquisition, zoning and permitting services described above.

Network development services segment operating profit for the three months ended September 30, 2010 was $4.5 million, a decrease of $0.2 million from the three months ended September 30, 2009. This decrease was comprised primarily of the $0.2 million decrease in network development services segment gross margin described above.

Depreciation, Amortization and Accretion

Depreciation, amortization and accretion for the three months ended September 30, 2010 was $115.4 million, an increase of $9.8 million from the three months ended September 30, 2009. This increase was primarily attributable to depreciation, amortization and accretion associated with the 7,517 sites acquired or constructed since July 1, 2009 and resulting increase in property and equipment and intangible assets subject to amortization.

Selling, General, Administrative and Development Expense

Selling, general, administrative and development expense for the three months ended September 30, 2010 was $57.3 million, an increase of $9.4 million from the three months ended September 30, 2009. This increase was primarily attributable to an increase of $4.9 million in payroll related costs, an increase of $2.6 million in consulting and professional fees and an increase of $1.9 million in various administrative expenses.

Other Operating Expenses

Other operating expenses for the three months ended September 30, 2010 were $4.3 million, an increase of $1.3 million from the three months ended September 30, 2009. The increase was primarily attributable to an increase of $3.7 million in acquisition related costs, partially offset by a decrease of $2.4 million of impairments and net losses on sale of long-lived assets.

Interest Expense

Interest expense for the three months ended September 30, 2010 was $62.9 million, a decrease of $1.2 million from the three months ended September 30, 2009. The decrease was primarily attributable to a decrease in the average borrowing rate.

Other Income

Other income for the three months ended September 30, 2010 was $8.2 million, as compared to other income of $0.1 million for the three months ended September 30, 2009. During the three months ended September 30, 2010, we recorded gains primarily associated with foreign currency translation of approximately $10.1 million, partially offset by other miscellaneous expenses of $1.9 million. During the three months ended September 30, 2009, we recorded foreign currency remeasurement gains of approximately $0.6 million, partially offset by other miscellaneous costs of $0.5 million.

Income Tax Provision

The income tax provision for the three months ended September 30, 2010 was $70.6 million, an increase of $19.3 million from the three months ended September 30, 2009. The effective tax rate was 43.0% for the three months ended September 30, 2010, as compared to an effective tax rate of 43.2% for the three months ended September 30, 2009.

The effective tax rates on income from continuing operations for the three months ended September 30, 2010 and September 30, 2009 differ from the federal statutory rate due primarily to adjustments for foreign items, non-deductible stock-based compensation expense, tax reserves and state taxes.

Total Revenues

Total revenues for the nine months ended September 30, 2010 were $1,437.7 million, an increase of $161.6 million from the nine months ended September 30, 2009. This increase was attributable to a $166.9 million increase in rental and management revenue, partially offset by a decrease of $5.3 million in network development services revenue.

Rental and Management Revenue

Rental and management revenue for the nine months ended September 30, 2010 was $1,400.1 million, an increase of $166.9 million from the nine months ended September 30, 2009. Legacy sites contributed $92.2 million of the increase, which was primarily attributable to incremental revenue generated from adding new tenants to those sites, existing tenants adding more equipment to those sites, contractual tenant lease escalations and the positive impact of foreign currency exchange rate fluctuations and straight-line revenue recognition, partially offset by tenant lease cancellations and a reduction in revenue recognized under a take or pay

agreement. Approximately $74.7 million of the increase resulted from the 7,884 new sites that we acquired and 1,695 new sites that we constructed since January 1, 2009. The increase in straight-line revenue was primarily the result of our successful completion of customer contract extensions in the United States and a master lease renegotiation with one of our large U.S. customers.

Network Development Services Revenue

Network development services revenue for the nine months ended September 30, 2010 was $37.6 million, a decrease of $5.3 million from the nine months ended September 30, 2009.

Rental and management segment operating profit for the nine months ended September 30, 2010 was $1,015.3 million, an increase of $118.5 million from the nine months ended September 30, 2009. This increase was comprised of the $128.9 million increase in rental and management segment gross margin described above, partially offset by an increase of $10.4 million in selling, general, administrative and development expenses related to our rental and management segment, due in large part to our international expansion, partially offset by a reduction in bad debt expense.

Network Development Services Expense/Segment Gross Margin/Segment Operating Profit

Network development services expense for the nine months ended September 30, 2010 was $20.1 million, a decrease of $5.2 million from the nine months ended September 30, 2009. The decrease correlates to the reduction in services performed as described above.

Selling, general, administrative and development expense for the nine months ended September 30, 2010 was $164.4 million, an increase of $9.0 million from the nine months ended September 30, 2009. This increase was primarily attributable to an increase of $11.2 million in payroll related costs, an increase of $6.2 million in consulting and professional fees and an increase of $1.6 million in various administrative expenses, partially offset by a decrease of $10.0 million in stock based compensation expense which was principally driven by the additional expense recognized upon the modification of vesting and exercise terms for a certain employee’s equity awards in 2009.

Other Operating Expenses

Other operating expenses for the nine months ended September 30, 2010 were $14.1 million, an increase of $5.9 million from the nine months ended September 30, 2009. The increase was primarily attributable to an increase of $8.4 million in acquisition related costs, partially offset by a decrease of $2.5 million of impairments and net losses on sale of long-lived assets.

Interest Expense

Interest expense for the nine months ended September 30, 2010 was $177.4 million, a decrease of $11.0 million from the nine months ended September 30, 2009. The decrease was primarily attributable to a decrease in the average borrowing rate.

September 30, 2009. Discrete items during the nine months ended September 30, 2010, which included a $32.6 million reduction in accrued income taxes from the implementation of restructuring activities in Latin America, as well as a net benefit of $17.3 million related to NOLs, reduced the effective tax rate for the period by approximately 9.9%.

The effective tax rates on income from continuing operations for the nine months ended September 30, 2010 and September 30, 2009 differ from the federal statutory rate due primarily to adjustments for foreign items, non-deductible stock-based compensation expense, tax reserves and state taxes.

Liquidity and Capital Resources

The information in this section updates as of September 30, 2010 the “Liquidity and Capital Resources” section of our Annual Report on Form 10-K for the year ended December 31, 2009 and should be read in conjunction with that report.

Overview

As a holding company, our cash flows are derived primarily from the operations of, and distributions from, our operating subsidiaries or funds raised through borrowings under our credit facilities and debt and equity offerings. As of September 30, 2010, we had approximately $1,218.8 million of total liquidity, comprised of approximately $371.9 million in cash and cash equivalents and the ability to borrow approximately $846.9 million under our $1.25 billion senior unsecured revolving credit facility (“Revolving Credit Facility”). In March 2008, we increased our borrowing capacity under the Revolving Credit Facility by adding $325.0 million of term loan commitments (“Term Loan”), and as of September 30, 2010, the Term Loan was fully drawn. On July 23, 2010, we borrowed $350.0 million under the Revolving Credit Facility, which, in addition to cash on hand, was used to finance the acquisition of Essar Telecom Infrastructure Private Limited (“ETIPL”). On August 16, 2010, we completed a registered public offering of $700.0 million aggregate principal amount of 5.05% senior unsecured notes due 2020 (“5.05% Notes”). We used $575.0 million of the net proceeds from this note offering to repay certain of our outstanding indebtedness incurred under the Revolving Credit Facility. On September 3, 2010, we entered into a 72.8 billion Colombian Peso-denominated revolving credit facility in connection with the purchase of the exclusive use rights for 225 towers from Telefónica S.A.’s Colombian subsidiary, Colombia Telecommunicaciones S.A. E.S.P. (“Coltel”).

Summary cash flow information for the nine months ended September 30, 2010 and 2009 is set forth below (in thousands).


	Nine Months Ended September 30,
	2010			2009
Net cash provided by (used for):
Operating activities	$	774,619		$	649,399
Investing activities		(859,160	)		(344,381	)

Net effect of changes in exchange rates on cash and cash equivalents		9,168			34

Net increase in cash and cash equivalents	$	124,585		$	86,597

We use our cash flows to fund our operations and investments in our business, including acquisitions, tower maintenance and improvements, tower construction, DAS network installations, and tower and land acquisitions. We also use our cash flows to fund refinancings and repurchases of our outstanding indebtedness, as well as our stock repurchase programs.

As of September 30, 2010, we had total outstanding indebtedness of approximately $4.8 billion. During the nine months ended September 30, 2010 and the year ended December 31, 2009, we generated sufficient cash

flow from operations to fund our capital expenditures and cash interest obligations. We believe the cash generated by operations during the next 12 months will be sufficient to fund our capital expenditures and our cash debt service (interest and principal repayments) obligations for the next 12 months.

Cash Flows from Operating Activities

For the nine months ended September 30, 2010, cash provided by operating activities was $774.6 million, an increase of $125.2 million as compared to the nine months ended September 30, 2009. This increase was primarily attributable to an increase of $118.3 million in the operating profit of our operating segments.

Each of our rental and management and network development services segments are expected to generate cash flows from operations during 2010 in excess of their cash needs for operations and expenditures for tower construction and improvements.

Cash Flows from Investing Activities

For the nine months ended September 30, 2010, cash used for investing activities was $859.2 million, an increase of $514.8 million as compared to the nine months ended September 30, 2009. This increase was primarily attributable to increased spending for acquisitions during nine months ended September 30, 2010.

During the nine months ended September 30, 2010, payments for purchases of property and equipment and construction activities totaled $228.5 million, including $133.2 million of capital expenditures for discretionary capital projects, such as completion of the construction of 654 towers, the installation of 13 in-building DAS networks and the installation of two outdoor DAS networks and the installation of shared back-up power generators, $49.8 million to acquire land under our towers that was subject to ground agreements (including leases), $28.9 million for capital improvements and corporate capital expenditures and $16.6 million related to redevelopment of our existing communications sites to accommodate new tenant equipment. In addition, during the nine months ended September 30, 2010, we spent $584.3 million to acquire 5,379 additional towers in the United States, Chile, Colombia, India and Peru.

We plan to continue to allocate our available capital among investment alternatives that meet our return on investment criteria. Accordingly, we may continue to acquire communications sites, acquire land under our towers, build or install new communications sites and redevelop or improve existing communications sites when the expected returns on such investments meet our return on investment criteria. We expect that our 2010 total capital expenditures will be between approximately $300 million and $320 million, including between $40 million and $45 million for capital improvements and corporate expenditures, between $30 million and $35 million for the redevelopment of existing communication sites, $60 million for ground lease purchases, and between $170 million and $180 million for other discretionary capital projects including the construction of approximately 1,000 to 1,200 new communications sites. In addition, we expect that we will spend approximately $600 million during the remainder of 2010 to acquire approximately 1,550 towers and 235 exclusive tower use rights internationally.

Cash Flows from Financing Activities

For the nine months ended September 30, 2010, cash provided by financing activities was $200.0 million, as compared to cash used for financing activities of $218.5 million during the nine months ended September 30, 2009. The $200.0 million of cash provided by financing activities during the nine months ended September 30, 2010 primarily related to $700.0 million ($693.6 million, net of discount, commissions and expenses) of proceeds from the issuance of the 5.05% Notes, the proceeds from stock options and SpectraSite, Inc. warrants of $122.3 million and borrowings under our credit facilities of $457.2 million, partially offset by payments for the repurchase of our Class A common stock (“Common Stock”) of $350.5 million, which consisted of $343.2 million of stock repurchases under our $1.5 billion program approved by our Board of Directors in February

2008 (the “2008 Buyback”) and $7.3 million of amounts surrendered for the satisfaction of employee tax obligations in connection with the vesting of restricted stock units and the repayment of notes payable, credit facilities and capital leases of $722.0 million. The $218.5 million of cash used for financing activities during the nine months ended September 30, 2009 primarily related to the tender offer for and redemption of the 7.50% senior unsecured notes due 2012, the repayment of credit facilities and capital leases of approximately $354.6 million, and payments for the repurchase of our Common Stock of $189.7 million, which consisted primarily of stock repurchases under our stock buyback program, partially offset by $300.0 million ($291.6 million, net of commissions and expenses) of proceeds from the issuance of the 7.25% senior unsecured notes due 2019 and approximately $36.0 million of proceeds from stock options, warrants and the employee stock purchase plan.

Revolving Credit Facility. As of September 30, 2010, we had $400.0 million outstanding and the ability to borrow approximately $846.9 million under the Revolving Credit Facility. On November 4, 2010, we entered into a definitive agreement to acquire towers in South Africa, which included providing a letter of credit for $30.0 million and consequently reduced our borrowings capacity by $30.0 million. We continue to maintain the ability to draw down and repay amounts under the Revolving Credit Facility in the ordinary course.

The borrower under the Revolving Credit Facility is American Tower Corporation. The Revolving Credit Facility has a term of five years and matures on June 8, 2012. Any outstanding principal and accrued but unpaid interest will be due and payable in full at maturity. The Revolving Credit Facility does not require amortization of principal and may be paid prior to maturity in whole or in part at our option without penalty or premium. The Revolving Credit Facility allows us to use borrowings for our and our subsidiaries’ working capital needs and other general corporate purposes (including, without limitation, to refinance or repurchase other indebtedness and, provided certain conditions are met, to repurchase our equity securities, in each case without additional lender approval).

Term Loan. On March 24, 2008, we entered into the $325.0 million Term Loan pursuant to the Revolving Credit Facility. At closing, we received net proceeds of approximately $321.7 million from the Term Loan, which, together with available cash, we used to repay $325.0 million of existing indebtedness under the Revolving Credit Facility. The Term Loan is governed by the terms of the loan agreement for the Revolving Credit Facility. Consistent with the terms of the Revolving Credit Facility, the borrower under the Term Loan is American Tower Corporation, and the maturity date for the Term Loan is June 8, 2012. Any outstanding principal and accrued but unpaid interest will be due and payable in full at maturity. The Term Loan does not require amortization of principal and may be paid prior to maturity in whole or in part at our option without penalty or premium.

5.05% Senior Notes Offering. On August 16, 2010, we completed a registered public offering of $700.0 million aggregate principal amount of our 5.05% Notes. The net proceeds to us from this offering were approximately $693.6 million, after deducting commissions and expenses. We used $575.0 million of the net proceeds to repay certain of our outstanding indebtedness incurred under the Revolving Credit Facility, which, along with cash on hand, was or will be used to finance the acquisition of ETIPL and other recent and potential acquisitions with the remainder used for general corporate purposes.

The 5.05% Notes mature on September 1, 2020, and interest is payable semi-annually in arrears on March 1 and September 1 of each year, beginning on March 1, 2011. We may redeem the 5.05% Notes at any time at a redemption price equal to 100% of the principal amount, plus a make-whole premium, together with accrued interest to the redemption date. Interest on the notes will accrue from August 16, 2010 and will be computed on the basis of a 360-day year comprised of twelve 30-day months.

If we undergo a change of control, as defined in the prospectus supplement to the prospectus dated May 13, 2010, and ratings decline (in the event that on, or within 90 days after, an announcement of a change of control, both of our current investment grade credit ratings cease to be investment grade), we will be required to offer to repurchase all of the 5.05% Notes at a purchase price equal to 101% of the principal amount, plus accrued and

unpaid interest (including additional interest, if any) up to but not including the repurchase date. The 5.05% Notes rank equally with all of our other senior unsecured debt and are structurally subordinated to all existing and future indebtedness and other obligations of our subsidiaries. The indenture contains certain covenants that restrict our ability to merge, consolidate or sell assets and our and our subsidiaries’ abilities to incur liens. These covenants are subject to a number of exceptions, including that we and our subsidiaries may incur certain liens on assets, mortgages or other liens securing indebtedness, if the aggregate amount of such liens does not exceed 3.5x Adjusted EBITDA, as defined in the indenture.

ETIPL Debt—At the time of our acquisition of ETIPL on August 6, 2010, ETIPL had in place term loans principally denominated in Indian Rupees in an amount equal to approximately 6.5 billion Indian Rupees, and a working capital loan in an amount equal to approximately 297.5 million Indian Rupees (“ETIPL Debt”). As of September 30, 2010, 6.5 billion Indian Rupees (approximately $144.6 million) was outstanding. As of October 20, 2010, we repaid all of the outstanding ETIPL Debt.

Colombian Short-Term Credit Facility—In connection with the purchase of the exclusive rights for 225 towers from Coltel, we entered into a 72.8 billion Colombian Peso-denominated revolving credit facility on September 3, 2010. The credit facility matures on March 2, 2011 and accrues interest at a rate of 6.50% that is payable upon maturity.

As of September 30, 2010, we had 58.0 billion Colombian Pesos (approximately $32.2 million) outstanding under this credit facility. On October 6, 2010, we borrowed the remaining 14.8 billion Colombian Pesos available under the facility in connection with the acquisition of an additional 160 towers and use rights in Colombia.

Stock Repurchase Program. During the nine months ended September 30, 2010, we repurchased an aggregate of 7.8 million shares of our Common Stock for an aggregate of $346.2 million, including commissions and fees, pursuant to the 2008 Buyback. Between October 1, 2010 and October 22, 2010, we repurchased a total of 551,690 shares of our Common Stock for an aggregate of $28.0 million, including commissions and fees. As of October 22, 2010, we had repurchased a total of 28.9 million shares of Common Stock for an aggregate of $1.1 billion, including commissions and fees, pursuant to our 2008 Buyback, and the remaining authorized amount for stock repurchases under the 2008 Buyback was $0.4 million.

Under the 2008 Buyback, we are authorized to purchase shares from time to time through open market purchases or privately negotiated transactions at prevailing prices in accordance with securities laws and other legal requirements, and subject to market conditions and other factors. To facilitate repurchases, we purchase our Common Stock pursuant to trading plans under Rule 10b5-1 of the Securities Exchange Act of 1934, as amended (“Exchange Act”), which allow us to repurchase shares during periods when we otherwise might be prevented from doing so under insider trading laws or because of self-imposed trading blackout periods.

In the near term, we expect to fund any further repurchases of our Common Stock through a combination of cash on hand, cash generated by operations and borrowings under our Revolving Credit Facility. Purchases under the 2008 Buyback are subject to us having available cash to fund repurchases.

Sales of Equity Securities. We receive proceeds from sales of our equity securities pursuant to our employee stock purchase plan, upon the exercise of stock options granted under our equity incentive plans and upon the exercise of warrants to purchase our equity securities. For the nine months ended September 30, 2010, we received an aggregate of approximately $122.3 million in proceeds upon exercises of stock options and upon exercises of warrants.

Contractual Obligations. Our contractual obligations relate primarily to the Commercial Mortgage Pass-Through Certificates, Series 2007-1 issued in our May 2007 securitization transaction (the “Securitization”), borrowings under our Revolving Credit Facility and Term Loan and our outstanding notes.

The following table summarizes our borrowings under our Revolving Credit Facility and Term Loan, and the balance outstanding under our notes and the certificates issued in the Securitization and certain other debt, as of September 30, 2010 (in thousands):

A description of our contractual debt obligations is set forth under the caption “Quantitative and Qualitative Disclosures about Market Risk” in Part I, Item 3 of this Quarterly Report on Form 10-Q. We classify uncertain tax positions as non-current income tax liabilities. We expect the unrecognized tax benefits to change over the next 12 months if certain tax matters ultimately settle with the applicable taxing jurisdiction during this timeframe. However, based on the status of these items and the amount of uncertainty associated with the outcome and timing of audit settlements, we are currently unable to estimate the impact of the amount of such changes, if any, to previously recorded uncertain tax positions and have classified approximately $26.0 million as other long-term liabilities in the condensed consolidated balance sheet as of September 30, 2010. We also classified approximately $18.0 million of accrued income tax related interest and penalties as other long-term liabilities in the condensed consolidated balance sheet as of September 30, 2010.

Refinancing Activities

In order to extend the maturity dates of our indebtedness, lower our cost of debt and improve our financial flexibility, we use our available liquidity and seek new sources of liquidity to refinance our outstanding indebtedness.

Redemption of ATI 7.25% Senior Subordinated Notes—During the nine months ended September 30, 2010, American Towers, Inc. (“ATI”) issued a notice for the redemption of the remaining $0.3 million aggregate principal amount of its 7.25% senior subordinated notes due 2011 (“ATI 7.25% Notes”). In accordance with the redemption provisions and the indenture for the ATI 7.25% Notes, the remaining ATI 7.25% Notes were redeemed at a price equal to 100.00% of the principal amount, plus accrued and unpaid interest up to, but excluding, September 23, 2010, for an aggregate purchase price of $0.3 million. Upon completion of this redemption, none of the ATI 7.25% Notes remained outstanding.

Factors Affecting Sources of Liquidity

As discussed in the “Liquidity and Capital Resources” section of our Annual Report on Form 10-K for the year ended December 31, 2009, our liquidity is dependent on our ability to generate cash flow from operating activities, borrow funds under our Revolving Credit Facility and maintain compliance with the contractual agreements governing our indebtedness. As discussed below, the loan agreements relating to the Securitization and to our Revolving Credit Facility and Term Loan contain certain financial ratios and operating covenants and other restrictions that could impact our liquidity. We believe that the foregoing debt agreements and indentures represent those of our material debt agreements that incorporate covenants, the compliance with which would be material to an investor’s understanding of our financial results and the impact of those results on our liquidity.

Restrictions Under Loan Agreement Relating to Revolving Credit Facility and Term Loan. The loan agreement for the Revolving Credit Facility and Term Loan contains certain financial ratios and operating covenants and other restrictions applicable to us and all of our subsidiaries designated as restricted subsidiaries on a consolidated basis. These include limitations on additional debt, distributions and dividends, guaranties, sales of assets and liens. The loan agreement also contains covenants that establish three financial tests with which we and our restricted subsidiaries must comply related to total leverage, senior secured leverage and interest coverage, as set forth below. As of September 30, 2010, we were in compliance with each of these covenants.

•

Consolidated Total Leverage Ratio: This ratio requires that we not exceed a ratio of Total Debt to Adjusted EBITDA (as defined in the loan agreement) of 6.00 to 1.00. Based on our financial performance for the 12 months ended September 30, 2010, we could incur approximately $2.85 billion of additional indebtedness and still remain in compliance with this ratio. In addition, if we maintain our existing debt levels and our expenses do not change materially from current levels, our revenues could decrease by approximately $475 million and we would still remain in compliance with this ratio.

•

Consolidated Senior Secured Leverage Ratio: This ratio requires that we not exceed a ratio of Senior Secured Debt to Adjusted EBITDA of 3.00 to 1.00. Based on our financial performance for the 12 months ended September 30, 2010, we could incur approximately $1.96 billion of additional Senior Secured Debt and still remain in compliance with this ratio. In addition, if we maintain our existing Senior Secured Debt levels and our expenses do not change materially from current levels, our revenues could decrease by approximately $653 million and we would still remain in compliance with this ratio.

•

Interest Coverage Ratio: This ratio requires that we maintain a ratio of Adjusted EBITDA to Interest Expense of not less than 2.50 to 1.00. Based on our financial performance for the 12 months ended September 30, 2010, our interest expense, which was $228 million for that period, could increase by approximately $272 million and we would still remain in compliance with this ratio. In addition, if our interest expense does not change materially from current levels, our revenues could decrease by approximately $680 million and we would still remain in compliance with this ratio.

The loan agreement also contains reporting and information covenants that require us to provide financial and operating information within certain time periods. If we are unable to provide the required information on a timely basis, we would be in breach of these covenants.

Any failure to comply with the financial maintenance tests and operating covenants of the loan agreement for the Revolving Credit Facility and Term Loan would not only prevent us from being able to borrow additional funds under the facility, but would constitute a default, which could result in, among other things, the amounts outstanding, including all accrued interest and unpaid fees, becoming immediately due and payable. If this were to occur, we would not have sufficient cash on hand to repay such indebtedness. The key factors affecting our ability to comply with the debt covenants described above are our financial performance relative to the financial maintenance tests defined in the loan agreement for the Revolving Credit Facility and Term Loan and our ability to fund our debt service obligations. Based upon our current expectations, we believe our operating results during the next twelve months will be sufficient to comply with these covenants.

Restrictions Under Loan Agreement Relating to Securitization Transaction. The loan agreement for the Securitization involves assets related to 5,295 broadcast and wireless communications towers owned by two special purpose subsidiaries of the Company (the “Borrowers”), through a private offering of $1.75 billion of Commercial Mortgage Pass-Through Certificates, Series 2007-1 (the “Certificates”). The Securitization loan agreement includes certain financial ratios and operating covenants and other restrictions customary for loans subject to rated securitizations. Among other things, the Borrowers are prohibited from incurring other indebtedness for borrowed money or further encumbering their assets. The Borrowers’ organizational documents contain provisions consistent with rating agency securitization criteria for special purpose entities, including the requirement that the Borrowers maintain at least two independent directors. The Securitization loan agreement also contains certain covenants that require the Borrowers to provide the trustee with regular financial reports and operating budgets, promptly notify the trustee of events of default and material breaches under the Securitization loan agreement and other agreements related to the towers subject to the Securitization, and allow the trustee reasonable access to the towers, including the right to conduct site investigations.

Under the terms of the Securitization loan agreement, the loan will be paid solely from the cash flows generated by the towers subject to the Securitization, which must be deposited, and thereafter distributed, solely pursuant to the terms of the Securitization loan. The Borrowers are required to make monthly payments of interest on the Securitization loan. On a monthly basis, all cash flow in excess of amounts required to make debt service payments, to fund required reserves, to pay management fees and budgeted operating expenses and to make other payments required under the Securitization loan, referred to as excess cash flow, is to be released to the Borrowers for distribution to us. During the nine months ended September 30, 2010, the Borrowers distributed excess cash to us of approximately $327.4 million.

In order to distribute this excess cash flow to us, the Borrowers must maintain several specified ratios with respect to their debt service coverage (“DSCR”). For this purpose, DSCR is tested as of the last day of each calendar quarter and is generally defined as four times the Borrowers’ net cash flow for that quarter divided by the amount of interest, servicing fees and trustee fees that the Borrowers must pay over the succeeding 12 months on the Securitization loan. Pursuant to one such test, if the DSCR as of the end of any calendar quarter were:

•

1.30x or less, during the five-year period commencing on the closing date of the Securitization in May 2007, or

•

1.75x or less, thereafter, (1.30x or 1.75x as applicable, the “Cash Trap DSCR”),

then all excess cash flow would be placed in a reserve account and would not be released to the Borrowers for distribution to us until the DSCR exceeded the Cash Trap DSCR for two consecutive calendar quarters.

Additionally, while principal payments generally are not due with respect to any component of the Securitization loan until April 2014, excess cash flow would be applied to principal during an “Amortization Period” under the Securitization loan until April 2014. An “Amortization Period” would commence under the Securitization loan if the DSCR as of the end of any calendar quarter fell below:

•

1.15x, during the five-year period commencing on the closing date of the Securitization in May 2007, or

•

1.45x thereafter (1.15x or 1.45x as applicable, the “Minimum DSCR”).

In such a case, all excess cash flow and any amounts then in the reserve account because the Cash Trap DSCR was not met would be applied to pay principal of the Securitization loan on each monthly payment date until the DSCR exceeded the Minimum DSCR for two consecutive calendar quarters, and so would not be available for distribution to us.

Consequently, a failure to comply with the covenants in the Securitization loan agreement could prevent the Borrowers from taking certain actions with respect to the towers. Additionally, a failure to meet the noted DSCR

tests could prevent the Borrowers from distributing excess cash flow to us, which could affect our ability to fund our discretionary expenditures, including tower construction and acquisitions, and our stock repurchase programs. In addition, if the Borrowers were to default on the loan related to the Securitization, the trustee could seek to foreclose upon or otherwise convert the ownership of the towers subject to the Securitization, in which case we could lose the towers and the revenue associated with the towers.

As of the end of the quarter ended September 30, 2010, the Borrowers’ DSCR was 3.24x. Based on the Borrowers’ net cash flow for the calendar quarter ended September 30, 2010 and the amount of interest, servicing fees and trustee fees payable over the succeeding 12 months on the Securitization loan, the Borrowers could endure a reduction of approximately $191.0 million in net cash flow before triggering a Cash Trap DSCR, and approximately $205.8 million in net cash flow before triggering an Amortization Period.

As discussed above, we use our available liquidity and seek new sources of liquidity to refinance and repurchase our outstanding indebtedness. In addition, in order to fund future growth and expansion initiatives and fund our stock repurchase program, we may need to raise additional capital through financing activities. If we determine that it is desirable or necessary to raise additional capital, we may be unable to do so, or such additional financing may be prohibitively expensive or restricted by the terms of our outstanding indebtedness. If we are unable to raise capital when our needs arise, we may not be able to fund future growth and expansion initiatives, refinance our existing indebtedness or fund our stock repurchase programs.

In addition, our liquidity depends on our ability to generate cash flow from operating activities. As set forth under the caption “Risk Factors” in Part II, Item 1A. of this Quarterly Report on Form 10-Q, we derive a substantial portion of our revenues from a small number of customers and, consequently, a failure by a significant customer to perform its contractual obligations to us could adversely affect our cash flow and liquidity. As also set forth in that Item, our largest international customer, Grupo Iusacell, which represented approximately 4% of our total revenues for the nine months ended September 30, 2010, has been engaged in a restructuring of its U.S. Dollar denominated debt since the first quarter of 2009. Effective April 1, 2010, we renegotiated our agreements with Grupo Iusacell to include, among other changes, the conversion of our accounts receivable, net, and associated value added tax, to a long-term interest bearing receivable to be repaid over five years. As of September 30, 2010, the long-term interest bearing receivable was $19.8 million and the related assets (which include financing lease commitments and a deferred asset that are primarily long-term in nature) were $47.6 million.

For more information regarding the terms of our outstanding indebtedness, please see note 6 to our consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2009.

Critical Accounting Policies and Estimates

Management’s discussion and analysis of financial condition and results of operations are based upon our condensed consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, as well as related disclosures of contingent assets and liabilities. We evaluate our policies and estimates on an ongoing basis, including those related to impairment of assets, asset retirement obligations, revenue recognition, stock-based compensation, income taxes, and estimated useful lives of assets, which we discussed in our Annual Report on Form 10-K for the year ended December 31, 2009. Management bases its estimates on historical experience and other various assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

We have reviewed our policies and estimates to determine our critical accounting policies for the nine months ended September 30, 2010. We have made no material changes to the critical accounting policies described in our Annual Report on Form 10-K for the year ended December 31, 2009, other than the adoption of the accounting pronouncements discussed below.

Recently Adopted Accounting Standards

In January 2010, the Financial Accounting Standards Board (“FASB”) issued guidance clarifying existing disclosure requirements and adding disclosure requirements with respect to fair value measurements. This guidance was effective for us as of January 1, 2010 and had no impact on our condensed consolidated results of operations or financial position.

Accounting Standards Updates

In October 2009, the FASB issued new guidance which establishes accounting and reporting guidance for arrangements including multiple revenue-generating activities. This guidance requires companies to allocate the overall consideration to each deliverable under the arrangement using the estimated selling prices in the absence of vendor specific objective evidence or third-party evidence of selling price for deliverables. This guidance is effective for any contracts entered into, or materially modified after January 1, 2011, with early adoption available. We are evaluating the impact, if any, that this update will have on our condensed consolidated results of operations and financial position.

ITEM 3.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to market risk from changes in interest rates on long-term debt obligations. We attempt to reduce these risks by utilizing derivative financial instruments, namely interest rate swaps. As of September 30, 2010, we held thirteen interest rate swap agreements, all of which have been designated as cash flow hedges, and which have an aggregate notional amount of $625.0 million, interest rates ranging from 2.86% to 4.08% and expiration dates through March 2011.

The following tables provide information as of September 30, 2010 about our market risk exposure associated with changing interest rates. For long-term debt obligations, the table presents principal cash flows by maturity date and average interest rates related to outstanding obligations.

As of September 30, 2010

(a)

As of September 30, 2010, variable rate debt consisted of our Revolving Credit Facility ($400.0 million drawn) and Term Loan ($325.0 million) included above based on the June 8, 2012 maturity date. As of September 30, 2010, fixed rate debt consisted of: the Certificates issued in the Securitization ($1.75 billion); the 7.25% senior notes due 2019 ($300.0 million principal amount due at maturity, the balance as of September 30, 2010 was $295.3 million); the 7.00% senior notes due 2017 ($500.0 million); the 4.625% senior notes due 2015 ($600.0 million principal amount due at maturity, the balance as of September 30, 2010 was $599.3 million); the 5.05% senior notes due 2020 ($700.0 million principal amount due at maturity, the balance as of September 30, 2010 was $699.2 million); and other debt of $236.2 million (including the ETIPL Debt, which was repaid on October 20, 2010, and Colombian Short-Term Credit Facility). Interest on the Revolving Credit Facility and Term Loan is payable in accordance with the applicable London Interbank Offered Rate (“LIBOR”) agreement or quarterly and accrues at our option either at LIBOR plus margin (as defined) or the base rate plus margin (as defined). The weighted average interest rate in effect at September 30, 2010 for the Revolving Credit Facility and Term Loan was 3.24%. For the nine months ended September 30, 2010, the weighted average interest rate under the Revolving Credit Facility and Term Loan was 3.01%.

(b)	Includes notional amount of $100.0 million that expires in December 2010.

(c)	Includes notional amounts of $525.0 million that expire between January and March 2011.

(d)	Represents the weighted-average fixed rate or range of interest based on contractual notional amount as a percentage of total notional amounts in a given year.

Changes in interest rates can cause interest charges to fluctuate on our variable rate debt. Variable rate debt as of September 30, 2010, after giving effect to our interest rate swap agreements, was comprised of $50.0 million under the Revolving Credit Facility and $50.0 million under the Term Loan. A 10% increase, or approximately 32 basis points, in current interest rates would have caused an additional pre-tax charge to our net income and an increase in our cash outflows of $0.2 million for the nine months ended September 30, 2010.

We are exposed to market risk from changes in foreign currency exchange rates primarily in connection with our foreign subsidiaries in Brazil, Chile, Colombia, India, Mexico and Peru. Any transaction denominated in a currency other than the U.S. Dollar is reported in U.S. Dollars at the applicable exchange rate. All assets and liabilities are translated into U.S. Dollars at exchange rates in effect at the end of the applicable fiscal reporting period and all revenues and expenses are translated at average rates for the period. The cumulative translation effect is included in stockholders’ equity and as a component of comprehensive income.

For the three months ended September 30, 2010, approximately 19% of our revenues and approximately 26% of our operating expenses were denominated in foreign currencies, as compared to 16% and 20%, respectively, during the same period in 2009. For the nine months ended September 30, 2010, approximately 18% of our revenues and approximately 23% of our operating expenses were denominated in foreign currencies, as compared to 14% and 18%, respectively, during the same period in 2009.

We have performed a sensitivity analysis assuming a hypothetical 10% adverse movement in foreign currency exchange rates from the quoted foreign currency exchange rates at September 30, 2010. As of September 30, 2010, the analysis indicated that such an adverse movement would not have a material effect on our revenue, operating results or cash flows.

ITEM 4.

CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

We have established disclosure controls and procedures to ensure that material information relating to us, including our consolidated subsidiaries, is made known to the officers who certify our financial reports and to other members of senior management and the Board of Directors.

Our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on this evaluation, our principal executive officer and principal financial officer concluded that these disclosure controls and procedures are effective and designed to ensure that the information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the requisite time periods specified in the applicable rules and forms, and that it is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There have not been any changes in our internal control over financial reporting during the three months ended September 30, 2010 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

One of our subsidiaries, SpectraSite Communications, Inc. (“SCI”), is involved in a lawsuit brought in Mexico against a former Mexican subsidiary of SCI (the subsidiary of SCI was sold in 2002, prior to our merger with SCI’s parent in 2005). The lawsuit concerns a terminated tower construction contract and related agreements with a wireless carrier in Mexico. The primary issue for us is whether SCI itself can be found liable to the Mexican carrier. The trial and lower appellate courts initially found that SCI had no such liability in part because Mexican courts do not have full jurisdiction over SCI. Following several decisions by Mexican appellate courts, including the Supreme Court of Mexico, and related appeals by both parties, the current status of this case is that in September 2010, an intermediate appellate court issued a new decision reimposing liability on SCI. The damages assessed by the intermediate appellate court are approximately $6.7 million. On October 14, 2010, we filed a new constitutional appeal to again dispute the intermediate appellate court’s recent decision. As a result, at this stage of the proceeding, we are unable to determine whether the liability imposed on SCI by the September 2010 decision will survive or to estimate our share, if any, of that potential liability if the decision survives the pending appeal.

On June 3, 2010, Horse-Shoe Capital (“Horse-Shoe”), a company formed under the laws of the Republic of Mauritius, filed a complaint in the Supreme Court of the State of New York, New York County, with respect to Horse-Shoe’s sale of XCEL to American Tower Mauritius (“AT Mauritius”), our wholly-owned subsidiary formed under the laws of the Republic of Mauritius. The complaint names AT Mauritius, ATI and us as defendants, and the dispute concerns the timing and amount of distributions to be made by AT Mauritius to Horse-Shoe from a $7.5 million holdback escrow account and a $15.7 million tax escrow account, each established by the transaction agreements at closing. The complaint seeks release of the entire holdback escrow account, plus an additional $2.8 million, as well as the release of approximately $12.0 million of the tax escrow account. The complaint also seeks punitive damages in excess of $69 million. We filed an answer to the complaint in August 2010, disputing both the amounts alleged to be owed under the escrow agreements as well as the timing of the escrow distributions. We also asserted in our answer that the demand for punitive damages is meritless. The parties have filed cross-motions for summary judgment concerning the release of the tax escrow account. Those motions and the other claims remain pending.

We periodically become involved in various claims and lawsuits that are incidental to our business. In our Annual Report on Form 10-K for the year ended December 31, 2009, we reported our material legal proceedings. Since the filing of our Annual Report, other than the legal proceedings discussed above, there have been no material developments with respect to any material legal proceedings to which we are a party. In the opinion of management, after consultation with counsel, other than the legal proceedings discussed above and in note 10 to our condensed consolidated financial statements included herein, there are no matters currently pending that would, in the event of an adverse outcome, have a material impact on our consolidated financial position, results of operations or liquidity.

ITEM 1A.

RISK FACTORS

Decrease in demand for our communications sites would materially and adversely affect our operating results and we cannot control that demand.

Many of the factors affecting the demand for our communications sites, and to a lesser extent our network development services, could materially and adversely affect our operating results. Those factors include:

•

a decrease in consumer demand for wireless services due to general economic conditions or other factors;

•

the financial condition of wireless service providers;

•

the ability and willingness of wireless service providers to maintain or increase capital expenditures;

•

the growth rate of wireless communications or of a particular wireless segment;

•

governmental licensing of spectrum;

•

mergers or consolidations among wireless service providers;

•

increased use of network sharing, roaming or resale arrangements by wireless service providers;

•

delays or changes in the deployment of next generation wireless technologies;

•

zoning, environmental, health or other government regulations or changes in the application or enforcement thereof; and

•

technological changes.

Any downturn in the economy or disruption in the financial and credit markets could have an impact on consumer demand for wireless services. If wireless service subscribers significantly reduce their minutes of use, or fail to widely adopt and use wireless data applications, our wireless carrier customers could experience a decrease in demand for their services. As a result, they may scale back their business plans or otherwise reduce their spending, which could materially and adversely affect demand for our communications sites and our network development services business, which could have a material adverse effect on our business, results of operations and financial condition.

Furthermore, the demand for broadcast space is dependent on the needs of television and radio broadcasters. Among other things, technological advances, including the development of satellite-delivered radio and video services, may reduce the need for tower-based broadcast transmission. In addition, as we continue to work with our customers during the transition from analog-based transmissions to digital-based transmissions, any significant increase in attrition rate or decrease in overall demand for broadcast space could have a material adverse effect on our business, results of operations and financial condition.

If our wireless service provider customers consolidate or merge with each other to a significant degree, our growth, revenue and ability to generate positive cash flows could be materially and adversely affected.

Significant consolidation among our wireless service provider customers may result in the decommissioning of certain existing communications sites, because certain portions of their networks may be redundant, and a reduction in future capital expenditures in the aggregate, because their expansion plans may be similar. For example, in connection with the combinations of Verizon Wireless and ALLTEL (to form Verizon Wireless), Cingular and AT&T Wireless (to form AT&T Mobility) and Sprint PCS and Nextel (to form Sprint Nextel) in the United States, and of Iusacell Celular and Unefon (now under the common ownership of Grupo Iusacell) in Mexico, the combined companies rationalized duplicative parts of their networks, which has led to the decommissioning of certain equipment on our communications sites. In addition, certain combined companies have undergone or are currently undergoing a modernization of their networks, and these and other customers could determine not to renew leases with us as a result. Our future results may be negatively impacted if a significant number of these contracts are terminated, and our ongoing contractual revenues would be reduced as a result. Similar consequences might occur if wireless service providers engage in extensive sharing, roaming or resale arrangements as an alternative to leasing on our communications sites.

Our leverage and debt service obligations may materially and adversely affect us.

As of September 30, 2010, we had approximately $4.8 billion of consolidated debt, and the ability to borrow additional amounts of approximately $846.9 million ($816.9 million as of November 4, 2010) under the Revolving Credit Facility. Our substantial level of indebtedness increases the possibility that we may be unable to generate cash sufficient to pay when due the principal of, interest on, or other amounts due with respect to our indebtedness. We are also permitted, subject to certain restrictions under our existing indebtedness, to draw down on our Revolving Credit Facility, obtain additional long-term debt and working capital lines of credit to meet future financing needs. This would have the effect of increasing our total leverage.

Our leverage could have significant negative consequences on our financial condition and results of operations, including:

•

impairing our ability to meet one or more of the financial ratio covenants contained in our debt agreements or to generate cash sufficient to pay interest or principal due under those agreements, which could result in an acceleration of some or all of our outstanding debt and the loss of towers subject to the Securitization if an uncured default occurs;

•

increasing our vulnerability to general adverse economic and industry conditions;

•

limiting our ability to obtain additional debt or equity financing;

•

increasing our borrowing costs if our current investment grade debt ratings decline;

•

requiring the dedication of a substantial portion of our cash flow from operations to service our debt, thereby reducing the amount of our cash flow available for other purposes, including capital expenditures;

•

requiring us to sell debt or equity securities or to sell some of our core assets, possibly on unfavorable terms, to meet payment obligations;

•

limiting our flexibility in planning for, or reacting to, changes in our business and the markets in which we compete;

•

limiting our ability to repurchase our Common Stock; and

•

placing us at a possible competitive disadvantage to less leveraged competitors and competitors that may have better access to capital resources.

Restrictive covenants in the loan agreement for the Revolving Credit Facility and Term Loan, the indentures governing our debt securities, and the loan agreement related to our Securitization could materially and adversely affect our business by limiting flexibility.

The loan agreement for the Revolving Credit Facility and the Term Loan contain restrictive covenants, as well as requirements to comply with certain leverage and other financial maintenance tests, and thus require that we limit our ability to take various actions, including incurring additional debt, guaranteeing indebtedness and engaging in various types of transactions, including mergers, acquisitions and sales of assets. Additionally, our indentures restrict our and our subsidiaries’ ability to incur liens securing our or their indebtedness. These covenants could place us at a disadvantage compared to some of our competitors, who may have fewer restrictive covenants and may not be required to operate under these restrictions. Further, these covenants could have an adverse effect on our business by limiting our ability to take advantage of financing, new tower development, mergers and acquisitions or other opportunities.

The loan agreement related to our Securitization includes operating covenants and other restrictions customary for loans subject to rated securitizations. Among other things, the borrowers under the loan agreement for the Securitization are prohibited from incurring other indebtedness for borrowed money or further encumbering their assets. A failure to comply with the covenants in the loan agreement could prevent the borrowers from taking certain actions with respect to the towers subject to the Securitization, and could prevent the borrowers from distributing any excess cash from the operation of such towers to us. If the borrowers were to default on the loan, the servicer on the loan could seek to foreclose upon or otherwise convert the ownership of the towers subject to the Securitization, in which case we could lose such towers and the revenue associated with such towers.

In addition, reporting and information covenants in our loan agreements and indentures require that we provide financial and operating information within certain time periods. If we are unable to timely provide the required information, we would be in breach of these covenants. For more information regarding the covenants and requirements discussed above, please see Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2009 under the caption “Management’s Discussion and Analysis of Financial Condition and

Results of Operations—Liquidity and Capital Resources—Factors Affecting Sources of Liquidity” and note 6 to our consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2009.

We could suffer adverse tax or other financial consequences if taxing authorities do not agree with our tax positions, or we are unable to utilize our net operating losses.

We are periodically subject to a number of tax examinations by taxing authorities in the states and countries where we do business, and we expect that we will continue to be subject to tax examinations in the future. In addition, U.S. federal, state and local, as well as international, tax laws and regulations are extremely complex and subject to varying interpretations. We recognize tax benefits of uncertain tax positions when we believe the positions are more likely than not of being sustained upon a challenge by the relevant tax authority. We believe our judgments in this area are reasonable and correct, but there is no guarantee that our tax positions will not be challenged by relevant tax authorities or that we would be successful in any such challenge. If there are tax benefits that are challenged successfully by a taxing authority, we may be required to pay additional taxes or we may seek to enter into settlements with the taxing authorities, which could require significant payments or otherwise have a material adverse effect on our business, results of operations and financial condition.

In addition, we have significant deferred tax assets related to our NOLs in U.S. federal and state taxing jurisdictions. Generally, for U.S. federal and state tax purposes, NOLs can be carried forward and used for up to twenty years, and the tax years will remain subject to examination until three years after the applicable NOLs are used or expire. We may be limited in our ability to utilize the applicable NOLs to offset future taxable income, including significant portions obtained through acquisitions.

To the extent we believe that a position with respect to an NOL is not more likely than not to be sustained, we do not record the related deferred tax asset. In addition, for NOLs that meet the recognition threshold, we assess the recoverability of the NOL and establish a valuation allowance against the deferred tax asset related to the NOL if recoverability is questionable. Given the uncertainty surrounding the recoverability of certain of our NOLs, we have established a valuation allowance to offset the related deferred tax asset so as to reflect what we believe to be the recoverable portion of our NOLs.

Our ability to utilize our NOLs is also dependent, in part, upon us having sufficient future earnings to utilize our NOLs before they expire. If market conditions change materially and we determine that we will be unable to generate sufficient taxable income in the future to utilize our NOLs, we could be required to record an additional valuation allowance. We review our uncertain tax positions and the valuation allowances for our NOLs periodically and make adjustments from time to time, which can result in an increase or decrease to the net deferred tax asset related to our NOLs. Our NOLs are also subject to review and potential disallowance upon audit by the taxing authorities of the jurisdictions where the NOLs were incurred, and future changes in tax laws or interpretations of such tax laws could materially limit our ability to utilize our NOLs. If we are unable to use our NOLs or the use of our NOLs is limited, we may have to make significant payments or otherwise record charges or reduce our deferred tax assets, which could have a material adverse effect on our business, results of operations and financial condition.

Due to the long-term expectations of revenue from tenant leases, we are sensitive to changes in the creditworthiness and financial strength of our tenants.

Due to the long-term nature of our tenant leases, we, like others in the tower industry, are dependent on the continued financial strength of our tenants. Many wireless service providers operate with substantial leverage. In the past, we have had customers that have filed for bankruptcy, although to date these bankruptcies have not had a material adverse effect on our business or revenues. In addition, many of our customers and potential customers rely on capital raising activities to fund their operations and capital expenditures, and the downturn in the economy and the disruptions in the financial and credit markets have made it more difficult and more expensive

to raise capital. If our customers or potential customers are unable to raise adequate capital to fund their business plans, they may reduce their spending, which could materially and adversely affect demand for our communications sites and our network development services business. If, as a result of a prolonged economic downturn or otherwise, one or more of our significant customers experienced financial difficulties or filed for bankruptcy, it could result in uncollectible accounts receivable and an impairment on our deferred rent asset, tower asset, network location intangible asset, customer relationship intangible asset or customer base intangible asset. In addition, it could result in the loss of significant customers and all or a portion of our anticipated lease revenues from certain customers, all of which could have a material adverse effect on our business, results of operations and financial condition. For example, as discussed below in “—Risk Factors—A substantial portion of our revenue is derived from a small number of customers,” Grupo Iusacell suspended the debt service payment of its U.S. Dollar denominated debt to its bondholders and is currently in negotiations with those bondholders.

Our expansion initiatives may disrupt our operations or expose us to additional risk.

As we continue to acquire communications sites in our existing markets and expand into new markets, we are subject to a number of risks and uncertainties, including not meeting our return on investment criteria and financial objectives, increased costs, undisclosed and assumed liabilities and the diversion of managerial attention due to an acquisition. Acquisitions involve substantial operating and financial risks and no assurance can be given as to our future success in identifying, executing and integrating acquisitions. Our international expansion initiatives are subject to additional risks such as complex laws, regulations and business practices that may require additional resources and personnel, as well as those risks described below in “—Our foreign operations are subject to economic, political and other risks that could materially and adversely affect our revenues or financial position, including risks associated with foreign currency exchange rates.” Although we generally focus our international efforts in countries with relatively stable political and macroeconomic environments, growing, competitive wireless communications industries and multiple wireless carriers that are likely to outsource their communications site infrastructure needs to us, we are subject to several factors outside of our control, and no assurance can be given that our expansion initiatives will succeed and not materially and adversely affect our business, results of operations and financial condition.

Our foreign operations are subject to economic, political, regulatory and other risks that could materially and adversely affect our revenues or financial position, including risks associated with foreign currency exchange rates.

Our business operations in Latin America and India and our expansion into any other international geographic areas in the future, could result in adverse financial consequences and operational problems not typically experienced in the United States. For the nine months ended September 30, 2010, approximately 18% of our consolidated revenue was generated by our international operations. We anticipate that our revenues from our international operations may grow in the future. Accordingly, our business is subject to risks associated with doing business internationally, including:

•

changes in a specific country’s or region’s political or economic conditions;

•

laws and regulations that tax or otherwise restrict repatriation of earnings or other funds or otherwise limit distributions of capital;

•

laws and regulations that dictate how we operate our communications sites and conduct business, including zoning and environmental matters which may be applied retroactively to sites;

•

changes to existing or new tax laws directed specifically at the ownership and operation of communications sites, or our international acquisitions, which may be applied or enforced retroactively;

•

expropriation and governmental regulation restricting foreign ownership;

•

possible failure to comply with anti-bribery laws such as the Foreign Corrupt Practices Act and similar local anti-bribery laws;

•

uncertainties regarding legal or judicial systems, including inconsistencies between and within laws, regulations and decrees, and judicial application thereof;

•

health or similar issues, such as a pandemic or epidemic; and

•

difficulty in recruiting and retaining trained personnel.

In addition, we face risks associated with changes in foreign currency exchange rates, including those arising from our operations, investments and financing transactions related to our international business. Volatility in foreign currency exchange rates can also affect our ability to plan, forecast and budget for our international operations and expansion efforts. Our revenues earned from operations in Mexico are primarily denominated in the Mexican Peso, and our revenues earned from operations in Latin America and India are denominated in the local currencies. We have not historically engaged in significant currency hedging activities relating to our non-U.S. Dollar operations, and a weakening of these foreign currencies against the U.S. Dollar would have a negative impact on our reported revenues and operating profits, which could have a material adverse effect on our business, results of operations and financial condition.

A substantial portion of our revenue is derived from a small number of customers.

A substantial portion of our total operating revenues is derived from a small number of customers. For the nine months ended September 30, 2010:

•

Four customers accounted for approximately 60% of our revenues;

•

AT&T Mobility accounted for approximately 19% of our revenues;

•

Sprint Nextel accounted for approximately 16% of our revenues;

•

Verizon Wireless accounted for approximately 16% of our revenues; and

•

T-Mobile accounted for approximately 9% of our revenues.

Our largest international customer is Grupo Iusacell, which now controls both Iusacell Celular and Unefon in Mexico. Grupo Iusacell is under common control with TV Azteca. Grupo Iusacell accounted for approximately 4% of our total revenues for the nine months ended September 30, 2010. In addition, for the nine months ended September 30, 2010, we received $10.7 million in net interest income from TV Azteca on our net note receivable balance of $107.2 million.

If any of these customers is unwilling or unable to perform its obligations under our agreements with them, our revenues, results of operations, financial condition and liquidity could be materially and adversely affected. In the ordinary course of our business, we do occasionally experience disputes with our customers, generally regarding the interpretation of terms in our agreements. Although we have historically resolved these disputes in a manner that did not have a material adverse effect on us or our customer relationships, it is possible that such disputes could lead to a termination of our agreements with customers or a material modification of the terms of those agreements, either of which could have a material adverse effect on our business, results of operations and financial condition. If we are forced to resolve any of these disputes through litigation, our relationship with the applicable customer could be terminated or damaged, which could lead to decreased revenues or increased costs, resulting in a corresponding adverse effect on our business, results of operations and financial condition.

Grupo Iusacell has been engaged in a restructuring of its U.S. Dollar denominated debt since the first quarter of 2009, and on April 1, 2009, announced that one of its subsidiaries had suspended the debt service payment of its U.S. Dollar denominated debt as part of this restructuring. Effective April 1, 2010, we renegotiated our agreements with Grupo Iusacell to include, among other changes, an extension of the agreements’ minimum lease terms and an amendment to annual escalations included in the contractual terms, in exchange for a discount against Grupo Iusacell’s aggregate annual lease payments, a conversion of accounts receivable, net, and associated value added tax, to a long-term interest bearing receivable to be repaid over five years, and conversion

of all Grupo Iusacell obligations to the Company from U.S. Dollars to Mexican Pesos. As of September 30, 2010, the long-term interest bearing receivable was $19.8 million. We also had approximately $47.6 million of other Grupo Iusacell related assets as of September 30, 2010, which include financing lease commitments and accrued straight-line revenue that are primarily long-term in nature. If Grupo Iusacell is unable to restructure its other indebtedness, Grupo Iusacell may not be able to meet its operating obligations, including making payments to us in the future under our revised agreements, which could have a material adverse effect on our business and results of operations.

We anticipate that we may need additional financing to fund future growth and expansion initiatives, to refinance our existing indebtedness and to fund our stock repurchase program.

In order to fund future growth and expansion initiatives, refinance our existing indebtedness and fund our stock repurchase program, we may need to raise additional capital through financing activities. We believe our cash provided by operations for the year ending December 31, 2010 will be sufficient to fund our cash needs for operations, capital expenditures and cash debt service (interest and principal repayments) obligations for 2010. However, we anticipate that we may need to obtain additional sources of capital in the future to fund growth initiatives and to support additional return of capital to stockholders. If so, depending on market conditions, we may seek to raise capital through credit facilities or debt or equity offerings. Additionally, a downgrade of our credit rating below investment grade could negatively impact our ability to access credit markets or preclude us from obtaining funds on investment grade terms and conditions. Further, certain of our current debt instruments limit the amount of indebtedness we and our subsidiaries may incur. Additional financing, therefore, may be unavailable, more expensive or restricted by the terms of our outstanding indebtedness. If we are unable to raise capital when our needs arise, we may not be able to fund our stock repurchase program, refinance our existing indebtedness or fund future growth and expansion initiatives.

New technologies or changes in a customer’s business model could make our tower leasing business less desirable and result in decreasing revenues.

The development and implementation of new technologies designed to enhance the efficiency of wireless networks or changes in a customer’s business model could reduce the use and need for tower-based wireless services transmission and reception or have the effect of decreasing demand for tower space or reducing obtainable lease rates. Examples of such technologies include spectrally efficient air-link technologies which potentially can relieve some network capacity problems, could reduce the demand for tower-based antenna space. Additionally, certain complementary network technologies, such as femtocells, could offload a portion of network traffic away from the traditional tower-based networks, which would reduce the need for carriers to add more equipment at certain communications sites. Moreover, the emergence of alternative technologies could reduce the need for tower-based broadcast services transmission and reception. For example, the growth in delivery of wireless communication, radio and video services by direct broadcast satellites could materially and adversely affect demand for our antenna space. The development and implementation of any of these and similar technologies to any significant degree could have a material adverse effect on our business, results of operations and financial condition.

We could have liability under environmental laws.

Our operations, like those of other companies engaged in similar businesses, are subject to the requirements of various federal, state, local and foreign environmental and occupational safety and health laws and regulations, including those relating to the management, use, storage, disposal, emission and remediation of, and exposure to, hazardous and non-hazardous substances, materials and wastes. As the owner, lessee or operator of real property and facilities, we may be liable for substantial costs of investigation, removal or remediation of soil and groundwater contaminated by hazardous materials, without regard to whether we, as the owner, lessee or operator, knew of or were responsible for the contamination. We may also be liable for certain costs of remediating contamination at third party sites to which we sent waste for disposal, even if the original disposal

may have complied with all legal requirements at the time. Many of these laws and regulations contain information reporting and record keeping requirements. We cannot assure you that we are at all times in complete compliance with all environmental requirements. We may be subject to potentially significant fines or penalties if we fail to comply with any of these requirements. The requirements of these laws and regulations are complex, change frequently, and could become more stringent in the future. In certain jurisdictions, these laws and regulations could be applied or enforced retroactively. It is possible that these requirements will change or that liabilities will arise in the future in a manner that could have a material adverse effect on our business, results of operations and financial condition.

Our business is subject to government regulations and changes in current or future laws or regulations could restrict our ability to operate our business as we currently do.

Our business, and that of our customers, is subject to federal, state, local and foreign regulation, including by the Federal Aviation Administration (“FAA”), the U.S. Federal Communications Commission (“FCC”), the U.S. Environmental Protection Agency and the Occupational Safety and Health Administration. In the United States, both the FCC and the FAA regulate towers used for wireless communications and radio and television broadcasting and the FCC separately regulates transmitting devices operating on towers. Similar regulations exist in Latin America and India and other foreign countries regarding wireless communications and the operation of towers. In certain jurisdictions, these regulations could be applied or enforced retroactively. Local zoning authorities and community organizations are often opposed to construction in their communities and these regulations can delay, prevent or increase the cost of new tower construction, modifications, additions of new antennas to a site, or site upgrades, thereby limiting our ability to respond to customer demands and requirements. Existing regulatory policies may materially and adversely affect the associated timing or cost of such projects and additional regulations may be adopted which increase delays or result in additional costs to us, or that prevent such projects in certain locations. These factors could materially and adversely affect our business, results of operations and financial condition.

Increasing competition in the tower industry may create pricing pressures that may materially and adversely affect us.

Our industry is highly competitive, and our customers have numerous alternatives for leasing antenna space. Some of our competitors, such as national wireless carriers that allow collocation on their towers, are larger and may have greater financial resources than we do, while other competitors may have lower return on investment criteria than we do.

Our competition includes:

•

international, national and regional tower companies;

•

wireless carriers that own towers and lease antenna space to other carriers;

•

site development companies that purchase antenna space on existing towers for wireless carriers and manage new tower construction; and

•

alternative site structures (e.g., building rooftops, outdoor and indoor DAS networks, billboards and electric transmission towers).

Competitive pricing pressures for tenants on towers from these competitors could materially and adversely affect our lease rates and services income. In addition, we may not be able to renew existing customer leases or enter into new customer leases, resulting in a material adverse impact on our results of operations and growth rate. Increasing competition could also make the acquisition of high quality tower assets more costly. Any of these factors could materially and adversely affect our business, results of operations or financial condition.

If we are unable to protect our rights to the land under our towers, it could adversely affect our business and operating results.

Our real property interests relating to our towers consist primarily of leasehold and sub-leasehold interests, fee interests, easements, licenses and rights-of-way. A loss of these interests at a particular tower site may interfere with our ability to operate a tower and generate revenues. For various reasons, we may not always have the ability to access, analyze and verify all information regarding titles and other issues prior to completing an acquisition of communications sites, which can affect our rights to access and operate a site. From time to time we also experience disputes with landowners regarding the terms of ground agreements for land under a tower, which can affect our ability to access and operate a tower site. Further, for various reasons, landowners may not want to renew their ground agreements with us, they may lose their rights to the land, or they may transfer their land interests to third parties, including ground lease aggregators, which could affect our ability to renew ground agreements on commercially viable terms. Approximately 84% of the communications sites in our portfolio as of September 30, 2010 are located on land we do not own. Approximately 83% of the ground agreements for these sites have a final expiration date of 2019 and beyond. Our inability to protect our rights to the land under our towers may have a material adverse effect on our business, results of operations or financial condition.

If we are unable or choose not to exercise our rights to purchase towers that are subject to lease and sublease agreements at the end of the applicable period, our cash flows derived from such towers would be eliminated.

Our communications site portfolio includes towers that we operate pursuant to lease and sublease agreements that include a purchase option at the end of each lease period. If we are unable or choose not to exercise our rights to purchase towers under these agreements at the end of the applicable period, our cash flows derived from such towers would be eliminated. For example, our SpectraSite subsidiary has entered into lease or sublease agreements with affiliates of SBC Communications, a predecessor entity to AT&T Mobility, with respect to approximately 2,500 towers pursuant to which SpectraSite has the option to purchase the sites upon the expiration of the lease or sublease beginning in 2013. The aggregate purchase option price for the AT&T Mobility towers was approximately $442.9 million as of September 30, 2010, and will accrete at a rate of 10% per year to the applicable expiration of the lease or sublease of a site. We have entered into a similar agreement with ALLTEL, which completed its merger with Verizon Wireless in January 2009, with respect to approximately 1,800 towers, for which we have an option to purchase the sites upon the expiration of the lease or sublease beginning in 2016. The aggregate purchase option price for the ALLTEL towers was approximately $64.7 million as of September 30, 2010, and will accrete at a rate of 3% per year through the expiration of the lease or sublease period. At ALLTEL’s option, at the expiration of the sublease period, the purchase price would be payable in cash or with 769 shares of our Common Stock per tower. We may not have the required available capital to exercise our right to purchase these or other leased or subleased towers at the end of the applicable period. Even if we do have available capital, we may choose not to exercise our right to purchase such towers for business or other reasons. In the event that we do not exercise these purchase rights, or are otherwise unable to acquire an interest that would allow us to continue to operate these towers after the applicable period, we will lose the cash flows derived from such towers, which may have a material adverse effect on our business. In the event that we decide to exercise these purchase rights, the benefits of the acquisitions of such towers may not exceed the associated acquisition, compliance and integration costs, and our business, results of operations or financial condition could be materially and adversely affected.

Our towers or data centers may be affected by natural disasters and other unforeseen damage for which our insurance may not provide adequate coverage.

Our towers are subject to risks associated with natural disasters, such as ice and wind storms, tornadoes, floods, hurricanes and earthquakes, as well as other unforeseen damage. Any damage or destruction to our towers or data centers as a result of these or other risks would impact our ability to provide services to our customers and could materially and adversely impact our results of operation or financial condition. While we maintain

insurance coverage for natural disasters, we may not have adequate insurance to cover the associated costs of repair or reconstruction for a major future event. Further, we carry business interruption insurance, but such insurance may not adequately cover all of our lost revenues, including potential revenues from new tenants that could have been added to our towers but for the damage. If we are unable to provide services to our customers as a result of damage to our towers, it could lead to customer loss, resulting in a corresponding material adverse effect on our business, results of operations or financial condition.

Our costs could increase and our revenues could decrease due to perceived health risks from radio emissions, especially if these perceived risks are substantiated.

Public perception of possible health risks associated with cellular and other wireless communications technology could slow the growth of wireless companies, which could in turn slow our growth. In particular, negative public perception of, and regulations regarding, these perceived health risks could slow the market acceptance of wireless communications services and increase opposition to the development and expansion of tower sites. The potential connection between radio frequency emissions and certain negative health effects has been the subject of substantial study by the scientific community in recent years, and numerous health-related lawsuits have been filed against wireless carriers and wireless device manufacturers. If a scientific study or court decision resulted in a finding that radio frequency emissions posed health risks to consumers, it could negatively impact the market for wireless services, as well as our wireless carrier customers, which could materially and adversely affect our business, results of operations or financial condition. We do not maintain any significant insurance with respect to these matters.

Our historical stock option granting practices are still subject to governmental review, which could result in fines, penalties or other liability.

In May 2006, we announced that our Board of Directors had established a special committee of independent directors to conduct a review of our stock option granting practices and related accounting. Subsequent to the formation of the special committee, we received an informal letter of inquiry from the Securities and Exchange Commission, a subpoena from the office of the United States Attorney for the Eastern District of New York and an information document request from the Internal Revenue Service, each requesting documents and information related to our stock option grants and practices. We also received a request for information from the Department of Labor, which concluded its review in September 2008, with no action taken against us. We have cooperated with these governmental authorities to provide the requested documents and information. These governmental proceedings remain open, and the time period necessary to conclude these proceedings is uncertain and could require significant additional management and financial resources. Significant legal and accounting expenses related to these matters have been incurred to date, and we may still incur expenses in connection with this matter. Members of our senior management may still be subject to regulatory fines, penalties, enforcement actions or other liability, which could have a material adverse impact on our business, results of operations or financial condition. In addition, as a result of the special committee’s findings, we restated our historical financial statements for certain periods prior to March 31, 2006 to, among other things, record changes for stock-based compensation expense (and related tax effects) relating to certain past stock option grants.

ITEM 2.

UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

Issuer Purchases of Equity Securities

During the three months ended September 30, 2010, we repurchased a total of 3,173,900 shares of our Common Stock for an aggregate of $149.8 million, including commissions and fees, pursuant to our publicly announced stock repurchase program, as follows:


Period	Total Number of Shares Purchased		Average Price Paid per Share		Total Number of Shares Purchased as Part of Publicly Announced Plans or Programs		Approximate Dollar Value of Shares that May Yet be Purchased Under the Plans or Programs
July 2010 (1)		1,151,900	$	45.51		1,151,900	$	503.1
August 2010 (1)		965,600		46.51		965,600		458.2
September 2010 (1)		1,056,400		49.63		1,056,400		405.8

Total Third Quarter		3,173,900	$	47.18		3,173,900	$	405.8

(1)

Repurchases made pursuant to the $1.5 billion stock repurchase program publicly approved by our Board of Directors in February 2008. Under this program, our management is authorized to purchase shares from time to time through open market purchases or privately negotiated transactions at prevailing prices as permitted by securities laws and other legal requirements, and subject to market conditions and other factors. To facilitate repurchases, we make purchases pursuant to a trading plan under Rule 10b5-1 of the Exchange Act, which allows us to repurchase shares during periods when we otherwise might be prevented from doing so under insider trading laws or because of self-imposed trading blackout periods. This program may be discontinued at any time.

Since September 30, 2010, we have continued to repurchase shares of our Common Stock pursuant to our stock repurchase program. Between October 1, 2010 and October 22, 2010, we repurchased a total of 551,690 shares of our Common Stock for an aggregate of $28.0 million, including commissions and fees, pursuant to this program.
