AMERICAN TOWER CORPORATION AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

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

Business -American Tower Corporation is, through its various subsidiaries (collectively, "ATC" or the "Company"), one of the largest global real estate investment trusts and a leading independent owner, operator and developer of multitenant communications real estate. The Company's primary business is the leasing of space on multitenant communications sites to wireless service providers, radio and television broadcast companies, wireless data providers, government agencies and municipalities and tenants in a number of other industries. The Company also manages rooftop and tower sites for property owners, operates in-building and outdoor distributed antenna system ("DAS") networks, holds property interests under third-party communications sites and provides network development services that primarily support its rental and management operations.

ATC is a holding company that conducts its operations through its directly and indirectly owned subsidiaries and its joint ventures. ATC's principal domestic operating subsidiaries are American Towers LLC and SpectraSite Communications, LLC. ATC conducts its international operations primarily through its subsidiary, American Tower International, Inc., which in turn conducts operations through its various international holding and operating subsidiaries and joint ventures.

The Company operates as a real estate investment trust for U.S. federal income tax purposes ("REIT") and, therefore, is generally not subject to U.S. federal income taxes on its income and gains that it distributes to its stockholders, including the income derived from leasing space on its towers. However, the Company remains obligated to pay income taxes on earnings from its taxable REIT subsidiaries ("TRSs"). In addition, the Company's international assets and operations, including those designated as direct or indirect qualified REIT subsidiaries or other disregarded entities of a REIT (collectively, "QRSs"), continue to be subject to taxation in the foreign jurisdictions where those assets are held or those operations are conducted. As of June 30, 2015, the Company's QRSs included its domestic tower leasing business, most of its operations in Costa Rica, Germany and Mexico and a majority of its network development services segment and indoor DAS networks business.

On March 27, 2015, the Company significantly expanded its domestic portfolio by obtaining the exclusive right to lease, acquire or otherwise operate and manage 11,448 wireless communications sites from Verizon Communications Inc. ("Verizon") in the United States (the "Verizon Transaction").

The accompanying condensed consolidated financial statements have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission. The financial information included herein is unaudited; however, the Company believes that all adjustments (consisting primarily 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. 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, 2014 (the "2014 Form 10-K").

Principles of Consolidation and Basis of Presentation -The accompanying condensed consolidated financial statements include the accounts of the Company and those entities in which it has a controlling interest. Investments in entities that the Company does not control are accounted for using the equity or cost method, depending upon the Company's ability to exercise significant influence over operating and financial policies. All intercompany accounts and transactions have been eliminated.

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. The significant estimates in the accompanying condensed consolidated financial statements include impairment of long-lived assets (including goodwill), asset retirement obligations, revenue recognition, rent expense, stock-based compensation, income taxes and accounting for business combinations and acquisitions of assets. 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.

Accounting Standards Updates -In May 2014, the Financial Accounting Standards Board (the "FASB") issued new revenue recognition guidance, which requires an entity to recognize revenue in an amount that reflects the consideration to which the entity expects to be entitled in exchange for the transfer of promised goods or services to customers. The standard will replace most existing revenue recognition guidance in GAAP and will become effective on January 1, 2018. Early adoption is permitted for fiscal years, and interim periods within those years, beginning after December 15, 2016. The standard permits the use of either the retrospective or cumulative effect transition method and leases are not included in the scope of this standard. The Company is evaluating the impact this standard will have on its financial statements.

In June 2014, the FASB issued stock-based compensation guidance, which requires a performance target that could be achieved after the requisite service period be treated as a performance condition that affects vesting, rather than a condition that affects the grant-date fair value. The Company early adopted this guidance on a prospective basis during the six months ended June 30, 2015, and it did not have a material effect on the Company's financial statements.

In April 2015, the FASB issued new guidance on the presentation of debt issuance costs. The guidance requires debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of the related debt liability, consistent with debt discounts and premiums. The update requires retrospective application and the update is effective for annual reporting periods beginning after December 15, 2015. The Company does not expect the adoption of this guidance to have a material effect on its financial statements.

The acquired network location intangibles represent the value to the Company of the incremental revenue growth that could potentially be obtained from leasing the excess capacity on acquired communications sites. The acquired customer-related intangibles typically represent the value to the Company of customer contracts and relationships in place at the time of an acquisition, including assumptions regarding estimated renewals.

The Company amortizes its acquired network location intangibles and customer-related intangibles on a straight-line basis over their estimated useful lives. As of June 30, 2015, the remaining weighted average amortization period of the Company's intangible assets, excluding deferred financing costs and the TV Azteca Economic Rights detailed in note 5 to the Company's consolidated financial statements included in the 2014 Form 10-K, was approximately 16 years. Amortization of intangible assets for the three and six months ended June 30, 2015 was approximately $147.6 million and $258.1 million, respectively, and amortization of intangible assets for the three and six months ended June 30, 2014 was approximately $101.6 million and $204.2 million, respectively. Amortization expense excludes amortization of deferred financing costs, which is included in Interest expense on the condensed consolidated statements of operations. Based on current exchange rates, the Company expects to record amortization expense (excluding amortization of deferred financing costs) as follows over the remaining current year and the next five subsequent years (in millions):

5. Long-Term Obligations

Refinancing of GTP Acquisition Partners Securitization -On May 29, 2015, GTP Acquisition Partners I, LLC ("GTP Acquisition Partners"), one of the Company's wholly owned subsidiaries, repaid all amounts outstanding under the Secured Tower Revenue Notes, Global Tower Series 2011-1, Class C, Secured Tower Revenue Notes, Global Tower Series 2011-2, Class C and Class F and Secured Tower Revenue Notes, Global Tower Series 2013-1, Class C and Class F (the "Existing GTP AP Notes"), plus prepayment consideration and other costs and expenses related thereto, with cash on hand and proceeds from a private issuance (the "2015 Securitization") of $350.0 million of American Tower Secured Revenue Notes, Series 2015-1, Class A (the "Series 2015-1 Notes") and $525.0 million of American Tower Secured Revenue Notes, Series 2015-2, Class A (the "Series 2015-2 Notes," and together with the Series 2015-1 Notes, the "2015 Notes"). During each of the three and six months ended June 30, 2015, the Company recorded a loss on retirement of long-term obligations of $0.8 million, consisting of prepayment consideration, primarily offset by the write-off of the unamortized premium recorded in connection with the assumption of the Existing GTP AP Notes.

The 2015 Notes were issued by GTP Acquisition Partners pursuant to a Third Amended and Restated Indenture and related series supplements, each dated as of May 29, 2015 (collectively, the "Indenture"), between GTP Acquisition Partners and its subsidiaries (the "GTP Entities") and The Bank of New York Mellon, as

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

trustee. The Series 2015-1 Notes have an interest rate of 2.350%, an anticipated repayment date of June 15, 2020 and a final repayment date of June 15, 2045. The Series 2015-2 Notes have an interest rate of 3.482%, an anticipated repayment date of June 16, 2025 and a final repayment date of June 15, 2050.

Amounts due under the 2015 Notes will be paid solely from the cash flows generated from the operation of the 3,621 communications sites (the "Secured Sites") owned by the GTP Entities. GTP Acquisition Partners is required to make monthly payments of interest on the 2015 Notes, commencing in July 2015. Subject to certain limited exceptions (described below), no payments of principal will be required to be made prior to June 15, 2020, which is the anticipated repayment date for the Series 2015-1 Notes. On a monthly basis, after payment of all required amounts under the applicable agreement, the excess cash flows generated from the operation of the Secured Sites are released to GTP Acquisition Partners, which can then be distributed to, and used by, the Company. However, if the debt service coverage ratio ("DSCR"), generally calculated as the ratio of the net cash flow (as defined in the Indenture) to the amount of interest, servicing fees and trustee fees required to be paid over the succeeding 12 months on the principal amount of the 2015 Notes that will be outstanding on the next payment date were equal to or below 1.30x (the "Cash Trap DSCR") for such quarter, then 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 transaction documents, referred to as excess cash flow, will be deposited into a reserve account instead of being released to GTP Acquisition Partners. The funds in the reserve account will not be released to GTP Acquisition Partners unless the DSCR exceeds the Cash Trap DSCR for two consecutive calendar quarters.

Additionally, an "amortization period" commences if, as of the end of any calendar quarter, the DSCR falls below 1.15x (the "Minimum DSCR") and will continue to exist until the DSCR exceeds the Minimum DSCR for two consecutive calendar quarters. During an amortization period, all excess cash flow and any amounts then in the reserve account because the Cash Trap DSCR was not met would be applied to payment of the principal on the 2015 Notes.

The 2015 Notes may be prepaid in whole or in part at any time, provided such payment is accompanied by the applicable prepayment consideration. If prepayment occurs within 12 months of the anticipated repayment date with respect to the Series 2015-1 Notes, or 18 months of the anticipated repayment date with respect to the Series 2015-2 Notes, no prepayment consideration is due. If the Series 2015-1 Notes or the Series 2015-2 Notes have not been repaid in full on the applicable anticipated repayment date, additional interest will accrue on the unpaid principal balance of the applicable series of the 2015 Notes, and such series will begin to amortize on a monthly basis from excess cash flow.

The 2015 Notes are secured by (i) mortgages, deeds of trust and deeds to secure debt on substantially all of the Secured Sites and their operating cash flows, (ii) a security interest in substantially all of the personal property and fixtures of the GTP Entities, including GTP Acquisition Partners' equity interests in its subsidiaries and (iii) the rights of the GTP Entities under a management agreement. American Tower Holding Sub II, LLC, whose only material assets are its equity interests in GTP Acquisition Partners, has guaranteed repayment of the 2015 Notes and pledged its equity interests in GTP Acquisition Partners as security for such payment obligations.

The Indenture includes covenants customary for notes issued in rated securitizations. Among other things, the GTP Entities are prohibited from incurring other indebtedness for borrowed money or further encumbering their assets. The organizational documents of the GTP Entities contain provisions consistent with rating agency securitization criteria for special purpose entities, including the requirement that they maintain independent directors. The Indenture also contains certain covenants that require GTP Acquisition Partners to provide the trustee with regular financial reports and operating budgets, promptly notify the trustee of events of default and material breaches under the Indenture and other agreements related to the Secured Sites and allow the trustee reasonable access to the Secured Sites, including the right to conduct site investigations. Further, under the

Indenture, GTP Acquisition Partners is required to maintain reserve accounts, including for amounts received or due from tenants related to future periods, property taxes, insurance, ground rents, certain expenses and debt service. The $18.6 million held in the reserve accounts as of June 30, 2015 is classified as restricted cash on the Company's accompanying condensed consolidated balance sheet.

Securitized Debt -The Company has several securitizations in place. Cash flows generated by the sites that secure the securitized debt are only available for payment of such debt and are not available to pay the Company's other obligations or the claims of its creditors. However, subject to certain restrictions, the Company holds the right to the excess cash flows not needed to pay the securitized debt and other obligations arising out of the securitizations. The securitized debt is the obligation of the issuers thereof or borrowers thereunder, as applicable, and their subsidiaries, and not of the Company or its other subsidiaries.

Mexican Loan -In May 2015, upon maturity of its 5.2 billion Mexican Peso ("MXN") denominated unsecured bridge loan, the Company repaid the remaining outstanding principal balance of 3.9 billion MXN (approximately $251.2 million on the date of repayment) with cash on hand and borrowings under its multi-currency senior unsecured revolving credit facility entered into in June 2013, as amended (the "2013 Credit Facility").

BR Towers Credit Facility -On March 30, 2015, the Company repaid all amounts outstanding and terminated the Brazilian Reais ("BRL") denominated credit facility with Banco Nacional de Desenvolvimento Econômico e Social ("BNDES"), which allowed a subsidiary of BR Towers S.A. ("BR Towers") to borrow up to 48.1 million BRL through an intermediary bank, and which the Company assumed in connection with the acquisition of BR Towers in November 2014.

Brazil Credit Facility -In December 2014, one of the Company's Brazilian subsidiaries entered into a 271.0 million BRL-denominated credit facility with BNDES, which matures on January 15, 2022 (the "Brazil Credit Facility"). On May 18, 2015, the Brazilian subsidiary borrowed 40.0 million BRL (approximately $13.3 million on the date of borrowing) and maintains the ability to draw on the Brazil Credit Facility until December 30, 2016. The Brazil Credit Facility bears interest at a margin over the long-term interest rate, as defined by BNDES ("TJLP"), and the Special Clearance and Escrow System ("SELIC") as follows (BRL in millions):


	Maximum Borrowing Amount		Contractual Interest Rate
Tranche A		BRL 34.8		TJLP + 4.25%
Tranche B		BRL 34.8		SELIC + 4.25%
Tranche C		BRL 200.0		6.00%
Tranche D		BRL 1.4		TJLP

As of June 30, 2015, the weighted average interest rate on the borrowings under the Brazil Credit Facility was 11.1%.

2014 Credit Facility -During the six months ended June 30, 2015, the Company increased the maximum Revolving Loan Commitment (as defined in the loan agreement) under its senior unsecured revolving credit facility entered into in January 2012, as amended and restated in September 2014 (the "2014 Credit Facility") to $2.5 billion. Effective February 20, 2015, the Company received incremental commitments of $500.0 million, and as a result, has the ability to borrow up to $2.0 billion.

During the six months ended June 30, 2015, the Company borrowed an aggregate of $2.1 billion and repaid an aggregate of $1.3 billion of revolving indebtedness under the 2014 Credit Facility. The Company primarily used the borrowings to fund a portion of the Verizon Transaction.

2013 Credit Facility -During the six months ended June 30, 2015, the Company increased the maximum Revolving Loan Commitment (as defined in the loan agreement) under the 2013 Credit Facility to $3.5 billion. Effective February 20, 2015, the Company received incremental commitments of $750.0 million, and as a result, has the ability to borrow up to $2.75 billion.

During the six months ended June 30, 2015, the Company borrowed an aggregate of $2.6 billion and repaid an aggregate of $2.3 billion of revolving indebtedness under the 2013 Credit Facility. The Company primarily used the borrowings to (i) fund a portion of the Verizon Transaction, (ii) fund the TIM Celular S.A. ("TIM") acquisition and (iii) repay other indebtedness.

In July 2015, the Company borrowed an additional $850.0 million under the 2013 Credit Facility, which was primarily used to fund the Company's acquisition in Nigeria.

The 2014 Credit Facility and the 2013 Credit Facility do not require amortization of principal and may be paid prior to maturity in whole or in part at the Company's option without penalty or premium. The Company maintains the ability to draw down and repay amounts under each of the credit facilities in the ordinary course.

2013 Term Loan -In October 2013, the Company entered into an unsecured term loan (the "2013 Term Loan"). During the six months ended June 30, 2015, the maximum Incremental Term Loan Commitments (as defined in the agreement) was increased to $1.0 billion. Effective February 20, 2015, the Company borrowed an additional $500.0 million under the 2013 Term Loan.

The key terms under the 2014 Credit Facility, the 2013 Credit Facility and the 2013 Term Loan as of June 30, 2015 are as follows ($ in millions):


	Outstanding Balance		Undrawn LOC		Maturity Date			Current margin over LIBOR (2)			Current commitment fee (3)
2014 Credit Facility	$	1,980	$	7.5		January 31, 2020	(1)		1.250	%		0.150	%

(1)	Subject to two optional renewal periods.

(2)	LIBOR means the London Interbank Offered Rate.

(3)	Fee on undrawn portion of the credit facility.

Amendments to Bank Facilities -During the six months ended June 30, 2015, the Company entered into amendment agreements with respect to the 2014 Credit Facility, the 2013 Credit Facility and the 2013 Term Loan. After giving effect to these amendments, the Company's permitted ratio of Total Debt to Adjusted EBITDA (as defined in the loan agreements for each of the facilities) is (i) 7.25 to 1.00 for the quarter ended June 30, 2015, (ii) 7.00 to 1.00 for the quarters ended September 30, 2015 and December 31, 2015 and (iii) 6.00 to 1.00 thereafter.

Redemption of Senior Notes -On February 11, 2015, the Company redeemed all of the outstanding 4.625% senior notes due 2015 (the "4.625% Notes"), in accordance with the redemption provisions in the indenture, at a price equal to 100.5898% of the principal amount, plus accrued interest up to, but excluding, February 11, 2015, for an aggregate redemption price of approximately $613.6 million, including approximately $10.0 million in accrued and unpaid interest. On April 29, 2015, the Company redeemed all of the outstanding 7.000% senior notes due 2017 (the "7.000% Notes"), in accordance with the redemption provisions in the indenture, at a price

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

equal to 114.0629% of the principal amount, plus accrued and unpaid interest up to, but excluding, April 29, 2015, for an aggregate redemption price of approximately $571.7 million, including approximately $1.4 million in accrued and unpaid interest.

During each of the three and six month periods ended June 30, 2015, the Company recorded a loss on retirement of long-term obligations of $74.3 million related to the redemption of the 7.000% Notes, which included prepayment consideration, the remaining portion of unamortized deferred financing costs and the write-off of the remaining settlement cost of a treasury rate lock related to the 7.000% Notes. In addition, during the six months ended June 30, 2015, the Company recorded a loss on retirement of long-term obligations of $3.7 million related to the redemption of the 4.625% Notes, which included prepayment consideration and the remaining portion of the unamortized discount and deferred financing costs. Each redemption was funded with borrowings under the Company's existing credit facilities and cash on hand. Upon completion of these redemptions, none of the 4.625% Notes or the 7.000% Notes remained outstanding.

2.800% Senior Notes and 4.000% Senior Notes Offering -On May 7, 2015, the Company completed a registered public offering of $750.0 million aggregate principal amount of 2.800% senior unsecured notes due 2020 (the "2.800% Notes") and $750.0 million aggregate principal amount of 4.000% senior unsecured notes due 2025 (the "4.000% Notes"). The net proceeds from this offering were approximately $1,480.1 million, after deducting commissions and estimated expenses. The Company used the proceeds to repay existing indebtedness under the 2013 Credit Facility.

The 2.800% Notes will mature on June 1, 2020 and bear interest at a rate of 2.800% per annum. The 4.000% Notes will mature on June 1, 2025 and bear interest at a rate of 4.000% per annum. Accrued and unpaid interest on the notes will be payable in U.S. Dollars semi-annually in arrears on June 1 and December 1 of each year, beginning on December 1, 2015. Interest on the notes will accrue from May 7, 2015 and will be computed on the basis of a 360-day year comprised of twelve 30-day months.

The Company may redeem the notes at any time, in whole or in part, at the applicable redemption price. If the Company redeems the 2.800% Notes prior to May 1, 2020 or the 4.000% Notes prior to March 1, 2025, it will pay a redemption price equal to 100% of the principal amount of the notes plus a make-whole premium, together with accrued interest to the redemption date. If the Company redeems the 2.800% Notes on or after May 1, 2020 or the 4.000% Notes on or after March 1, 2025, it will not be required to pay a make-whole premium. In addition, if the Company undergoes a change of control and ratings decline, each as defined in the supplemental indenture, it may be required to repurchase all of the notes at a purchase price equal to 101% of the principal amount of the notes, plus accrued and unpaid interest (including additional interest, if any), up to but not including the repurchase date. The 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 supplemental indenture contains certain covenants that restrict the Company's ability to merge, consolidate or sell assets and its (together with its subsidiaries') ability 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 supplemental indenture.

6. Derivative Financial Instruments

Certain of the Company's foreign subsidiaries have entered into interest rate swap agreements, which have been designated as cash flow hedges, to manage exposure to variability in interest rates on debt.

South Africa

One of the Company's South African subsidiaries has 15 interest rate swap agreements outstanding, which mature on the earlier of termination of the underlying debt or March 31, 2020. These swap agreements provide that the Company pay a fixed interest rate ranging from 6.09% to 7.83% and receive variable interest at the three-month Johannesburg Interbank Agreed Rate (JIBAR) over the term of the interest rate swap agreements. The notional value is reduced in accordance with the repayment schedule under the related credit agreement.

Colombia

In connection with entering into a Colombian Peso ("COP") denominated credit facility in October 2014 (the "Colombian Credit Facility"), one of the Company's Colombian subsidiaries entered into an interest rate swap agreement with certain of the lenders under the Colombian Credit Facility. This swap agreement matures on the earlier of termination of the underlying debt or April 24, 2021 and provides that the Company pay a fixed interest rate of 5.74% and receive variable interest at the three-month Inter-bank Rate ("IBR") over the term of the agreement. The notional value is reduced in accordance with the repayment schedule under the Colombian Credit Facility.

In addition to the interest rate swap agreements, the Company was amortizing the settlement cost of a treasury rate lock as additional interest expense over the term of the 7.000% Notes. In connection with the redemption of the 7.000% Notes, the Company recognized $2.0 million of the remaining deferred loss on the settlement cost as a loss on retirement of long-term obligations in the condensed consolidated statements of operations.

7. Fair Value Measurements

The Company determines the fair value 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.

Interest Rate Swap Agreements

The fair value of the Company's interest rate swap agreements is determined using pricing models with inputs that are observable in the market or can be derived principally from, or corroborated by, observable market data. Fair valuations of the swap agreements reflect the value of the instrument including the values associated with counterparty risk, the Company's own credit standing and the value of the net credit differential between the counterparties to the derivative contract.

Acquisition-Related Contingent Consideration

Acquisition-related contingent consideration is initially measured and recorded at fair value as an element of consideration paid in connection with an acquisition with subsequent adjustments recognized in Other operating expenses in the condensed consolidated statements of operations. The Company determines the fair value of acquisition-related contingent consideration, and any subsequent changes in fair value, using a discounted probability-weighted approach. This approach takes into consideration Level 3 unobservable inputs including probability assessments of expected future cash flows over the period in which the obligation is expected to be settled and applies a discount factor that captures the uncertainties associated with the obligation. Changes in these unobservable inputs could significantly impact the fair value of the liabilities recorded in the accompanying condensed consolidated balance sheets and adjustments recorded in the condensed consolidated statements of operations.

Items Measured at Fair Value on a Nonrecurring Basis

Assets Held and Used -The Company's long-lived assets are measured at fair value on a nonrecurring basis using Level 3 inputs. During the three and six months ended June 30, 2015 and 2014, the Company did not record any asset impairment charges.

Assets Held-for-Sale -During the six months ended June 30, 2014, based on a strategic review of the international rental and management segment and components of the network development services segment, the Company determined that its operations in Panama and its third-party structural analysis business were held-for-sale. The Company recorded an impairment charge of $4.1 million during the three and six months ended June 30, 2014 to write down the intangibles and goodwill to fair value. The impairment charge was recorded in Other operating expenses in the accompanying condensed consolidated statements of operations and the adjustment was determined by comparing the estimated net proceeds from sale of assets or the projected future discounted cash flows to be provided from the long-lived assets (calculated using Level 3 inputs) to the asset's carrying value.

There were no other items measured at fair value on a nonrecurring basis during the six months ended June 30, 2015.

Fair Value of Financial Instruments -The Company's financial instruments for which the carrying value reasonably approximates fair value at June 30, 2015 and December 31, 2014 included cash and cash equivalents, restricted cash, accounts receivable and accounts payable. The Company's estimates of fair value of its long-term obligations, including the current portion, are based primarily upon reported market values. For long-term debt not actively traded, fair value is estimated using either indicative price quotes or a discounted cash flow analysis using rates for debt with similar terms and maturities. As of June 30, 2015, the carrying value and fair value of long-term obligations, including the current portion, were $16.2 billion and $16.5 billion, respectively, of which

$9.9 billion was measured using Level 1 inputs and $6.6 billion was measured using Level 2 inputs. As of December 31, 2014, the carrying value and fair value of long-term obligations, including the current portion, were $14.6 billion and $15.0 billion, respectively, of which $9.7 billion was measured using Level 1 inputs and $5.3 billion was measured using Level 2 inputs.

During each of the three and six months ended June 30, 2015, $2.0 million related to the deferred loss on the settlement of the treasury rate lock was reclassified from Accumulated other comprehensive loss into Loss on retirement of long-term obligations in connection with redemption of the 7.000% Notes. The remaining losses on cash flow hedges have been reclassified into Interest expense in the accompanying condensed consolidated statements of operations and the associated tax effect of less than $0.1 million for each of the three and six months ended June 30, 2015 and 2014, respectively, is included in Income tax provision.

9. 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 tax rate is determined. As a REIT, the Company continues to be subject to income taxes on the income of its TRSs and income taxation in foreign jurisdictions where it conducts international operations. Under the provisions of the Internal Revenue Code of 1986, as amended, the Company may deduct amounts distributed to stockholders against the income generated in its QRSs. The Company is able to offset income in both its TRSs and QRSs by utilizing their respective net operating losses.

In 2013, the Company acquired MIP Tower Holdings LLC ("MIPT"), which had been organized and qualified as a REIT. The Company intends to file a tax election pursuant to which MIPT will no longer operate as a separate REIT for federal and state income tax purposes, effective July 25, 2015. In connection with this election, the Company expects to incur a one-time cash tax charge of approximately $92.5 million, based on preliminary calculations, in the second half of 2015.

The Company provides valuation allowances if, based on the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. Management assesses the available positive and negative evidence to estimate if sufficient future taxable income will be generated to use the existing deferred tax assets.

As of June 30, 2015 and December 31, 2014, the total amount of unrecognized tax benefits that would impact the effective tax rate, if recognized, was approximately $31.9 million. The amount of unrecognized tax benefits during the three and six months ended June 30, 2015 includes additions to the Company's existing tax positions, partially offset by foreign currency fluctuations. 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 14 to the Company's consolidated financial statements included in the 2014 Form 10-K. The impact of the amount of these changes to previously recorded uncertain tax positions could range from zero to $8.1 million.

AMERICAN TOWER CORPORATION AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

The Company recorded penalties and income tax-related interest expense during the three and six months ended June 30, 2015 of $0.6 million and $1.5 million, respectively, and during the three and six months ended June 30, 2014 of $1.9 million and $3.2 million, respectively. As of June 30, 2015 and December 31, 2014, the total amount of accrued income tax related interest and penalties included in Other non-current liabilities in the condensed consolidated balance sheets was $24.5 million and $24.9 million, respectively.

10. Stock-Based Compensation

The Company recognized stock-based compensation expense during the three and six months ended June 30, 2015 of $24.0 million and $53.9 million, respectively, and stock-based compensation expense during the three and six months ended June 30, 2014 of $18.8 million and $43.4 million, respectively. The Company capitalized $0.6 million and $1.1 million of stock-based compensation expense as property and equipment during the three and six months ended June 30, 2015, respectively, and capitalized $0.4 million and $0.8 million of stock-based compensation expense as property and equipment during the three and six months ended June 30, 2014, respectively.

Summary of Stock-Based Compensation Plans -The Company maintains equity incentive plans that provide for the grant of stock-based awards to its directors, officers and employees. The 2007 Equity Incentive Plan (the "2007 Plan") provides for the grant of non-qualified and incentive stock options, as well as restricted stock units, restricted stock and other stock-based awards. Exercise prices in the case of non-qualified and incentive stock options are not less than the fair value of the underlying common stock on the date of grant. Equity awards typically vest ratably over various periods, generally four years for time-based restricted stock units ("RSUs") and stock options and three years for performance-based restricted stock units ("PSUs"). Stock options generally expire ten years from the date of grant. As of June 30, 2015, the Company had the ability to grant stock-based awards with respect to an aggregate of 11.6 million shares of common stock under the 2007 Plan.

The Company's Compensation Committee adopted a death, disability and retirement benefits program in connection with equity awards granted on or after January 1, 2013 that provides for accelerated vesting and extended exercise periods of stock options and restricted stock units upon an employee's death or permanent disability, or upon an employee's qualified retirement provided certain eligibility criteria are met. Accordingly, for grants made on or after January 1, 2013, the Company recognizes compensation expense for stock options and RSUs over the shorter of (i) the four-year vesting period or (ii) the period from the date of grant to the date the employee becomes eligible for such retirement benefits, which may occur upon grant; and recognizes compensation expense for PSUs over the three-year vesting period, subject to adjustment based on the date the employee becomes eligible for such retirement benefits.

Stock Options -The Company's option activity for the six months ended June 30, 2015 was as follows:


	Number of Options
Outstanding as of January 1, 2015		6,508,435
Granted		2,004,100
Exercised		(221,703	)
Forfeited		(93,021	)
Expired		(1,475	)

Outstanding as of June 30, 2015		8,196,336

Table of Contents

AMERICAN TOWER CORPORATION AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

The fair value of each option granted during the six months ended June 30, 2015 was estimated on the date of grant using the Black-Scholes option pricing model based on the assumptions noted in the table below.

Key assumptions used to apply this pricing model are as follows:


Range of risk-free interest rate		1.32%-1.62%
Weighted average risk-free interest rate		1.62%
Expected life of option grants		4.5 years
Range of expected volatility of underlying stock price		21.09%-21.20%
Weighted average expected volatility of underlying stock price		21.09%
Range of expected annual dividend yield		1.50%-1.85%

The weighted average grant date fair value per share during the six months ended June 30, 2015 was $15.09. As of June 30, 2015, total unrecognized compensation expense related to unvested stock options was $39.3 million and is expected to be recognized over a weighted average period of approximately two years.

Restricted Stock Units and Performance-Based Restricted Stock Units -The Company's RSU and PSU activity for the six months ended June 30, 2015 was as follows:


	RSUs			PSUs (1)
Outstanding as of January 1, 2015		1,758,817			-
Granted		692,340			23,379
Vested		(671,652	)		-
Forfeited		(70,695	)		-

Outstanding as of June 30, 2015		1,708,810			23,379

(1)	Represents the target number of shares issuable at the end of the three-year performance cycle attributable to the first year's performance period.

Restricted Stock Units- As of June 30, 2015, total unrecognized compensation expense related to unvested RSUs granted under the 2007 Plan was $100.0 million and is expected to be recognized over a weighted average period of approximately three years.

Performance-Based Restricted Stock Units -During the six months ended June 30, 2015, the Company granted an aggregate of 70,135 PSUs to its executive officers and established the performance metric for this award. Threshold, target and maximum parameters were established for the metric for each year in the three-year performance period, and will be used to calculate the number of shares that will be issuable when the award vests, which may range from zero to 200 percent of the target amount. At the end of the three-year performance period, the number of shares that are earned and vest will depend on the degree of achievement against the pre-established performance goal. PSUs that have been earned over the performance period will be paid out in common stock at the end of the performance period, subject generally to the executive's continued employment and will accrue dividend equivalents prior to vesting, which will be paid out only in respect of shares actually earned and vested. As the performance metric is tied to year-over-year growth and actual results for the metric will not be determined until the end of each respective fiscal year, the Company is unable to determine the annual target for the second and third years of the performance period for this award at this time. Accordingly, an aggregate of 46,756 PSUs granted on March 10, 2015 are not included in the table above. The grant date fair value per share of the PSUs for which terms have been established was $94.57.

During the three and six months ended June 30, 2015, the Company recorded $0.6 million and $0.7 million, respectively, in stock-based compensation expense for equity awards in which the performance goals have been

established and are probable of being achieved. The remaining unrecognized compensation expense related to these awards at June 30, 2015 was $1.6 million based on the Company's current assessment of the probability of achieving the performance goals. The weighted-average period over which the cost will be recognized is one year.

Employee Stock Purchase Plan -The Company maintains an employee stock purchase plan ("ESPP") pursuant to which eligible employees may purchase shares of the Company's common stock on the last day of each bi-annual offering period at a 15% discount of the lower of the closing market value on the first or last day of such offering period. The offering periods run from June 1 through November 30 and from December 1 through May 31 of each year. During the six months ended June 30, 2015, employee contributions were accumulated to purchase approximately 44,000 shares under the ESPP.

Key assumptions used to apply the Black-Scholes pricing model for shares purchased through the ESPP during the six months ended June 30, 2015, which resulted in a fair value per share of $16.40, were as follows:


Approximate risk-free interest rate	0.06	%
Expected life of shares	6 months
Expected volatility of underlying stock price over the option period	13.91	%
Expected annual dividend yield	1.85	%

11. Equity

12. Earnings Per Share

Basic net income per common share represents net income attributable to American Tower Corporation common stockholders divided by the weighted average number of common shares outstanding during the period. Diluted net income per common share represents net income attributable to American Tower Corporation common stockholders divided by the weighted average number of common shares outstanding during the period and any dilutive common share equivalents, including shares issuable upon (i) the vesting of restricted stock awards, (ii) exercise of stock options and (iii) conversion of the Company's Mandatory Convertible Preferred Stock. Dilutive common share equivalents also include the dilutive impact of the ALLTEL transaction (see note 13).

The Company uses the treasury stock method to calculate the effect of its outstanding restricted stock awards and stock options and uses the if-converted method to calculate the effect of its outstanding Mandatory Convertible Preferred Stock.

The following table sets forth basic and diluted net income per common share computational data for the three and six months ended June 30, 2015 and 2014 (in thousands, except per share data):

13. Commitments and Contingencies

Litigation

The Company periodically becomes involved in various claims, lawsuits and proceedings that are incidental to its business. In the opinion of Company management, after consultation with counsel, 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.

Lease Obligations

Tenant Leases -As part of the Verizon Transaction, the Company entered into leases or subleases with Verizon with respect to 11,448 communications sites with an initial non-cancellable term of ten years. In addition, the Company assumed the rights under the tenant leases that were in place on such sites at the time of the transaction. At the time of the transaction, the total estimated future minimum rental receipts under the non-cancellable Verizon leases and assumed third-party leases was approximately $3.0 billion and was expected to be recognized over an average period of approximately 10 years.

Lease Obligations -In connection with the Verizon Transaction, the Company assumed the interest in and obligations under certain ground leases. Many of the leases contain renewal options with specified increases in lease payments upon exercise of the renewal option. Escalation clauses present in operating leases, excluding those tied to the Consumer Price Index (CPI) or other inflation-based indices, are recognized on a straight-line basis over the non-cancellable term of the leases. Future minimum rental payments under non-cancellable operating leases include payments for certain renewal periods at the Company's option because failure to renew could result in a loss of the applicable communications sites and related revenues from tenant leases, thereby making it reasonably assured that the Company will renew the leases. At the time of the transaction, the Company's future minimum rental payments under non-cancellable operating leases, including certain renewal periods related to the Verizon communications sites, was approximately $2.2 billion and was expected to be recognized over an average period of approximately 17 years.

Commitments

Verizon Transaction -On March 27, 2015, the Company entered into an agreement with various operating entities of Verizon that provides for the lease, sublease or management of 11,285 wireless communications sites from Verizon commencing March 27, 2015. The average term of the lease or sublease for all sites at the inception of the agreement was approximately 28 years, assuming renewals or extensions of the underlying ground leases for the sites. The Company has the option to purchase the leased sites in tranches, subject to the applicable lease, sublease or management right upon its scheduled expiration. Each tower is assigned to an annual tranche, ranging from 2034 to 2047, which represents the outside expiration date for the sublease rights to the towers in each tranche. The purchase price for each tranche is a fixed amount stated in the sublease for such tranche plus the fair market value of certain alterations made to the related towers. The aggregate purchase option price for the towers leased and subleased is approximately $5.0 billion. Verizon will occupy the sites as a tenant for an initial term of ten years with eight optional successive five-year terms; each such term shall be governed by standard master lease agreement terms established as a part of the transaction.

AT&T Transaction -The Company has an agreement with SBC Communications Inc., a predecessor entity to AT&T Inc. ("AT&T"), that currently provides for the lease or sublease of approximately 2,400 towers from AT&T with the lease commencing between December 2000 and August 2004. Substantially all of the towers are part of the Company's securitization transaction completed in March 2013. 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

Table of Contents

AMERICAN TOWER CORPORATION AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

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. As of June 30, 2015, the Company has purchased an aggregate of 31 of the subleased towers upon expiration of the applicable agreement. The aggregate purchase option price for the remaining towers leased and subleased is approximately $675.3 million and will accrete at a rate of 10% per annum through 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 for the remainder of AT&T's tenancy. 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, a predecessor entity to Verizon Wireless, to acquire towers through a 15-year sublease agreement. Pursuant to the agreement, as amended, with Verizon Wireless, the Company acquired rights to 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 is approximately $74.2 million as of June 30, 2015. At the expiration of the sublease, the purchase price would be payable in cash or, at Verizon Wireless's or its assignee's option, as applicable, with 769 shares of the Company's common stock per tower, which would be valued at approximately $127.1 million in the aggregate based on the closing price at June 30, 2015.

Other Contingencies -The Company is subject to income tax and other taxes in the geographic areas where it operates, and periodically receives notifications of audits, assessments or other actions by taxing authorities. The Company evaluates the circumstances of each notification based on the information available and records a liability for any potential outcome that is probable or more likely than not unfavorable if the liability is also reasonably estimable. On January 21, 2014, the Company received an income tax assessment in the amount of 22.6 billion Indian Rupees (approximately $369.0 million on the date of assessment), asserting tax liabilities arising out of a transfer pricing review of transactions by Essar Telecom Infrastructure Private Limited. The Company challenged the assessment before India's Income Tax Appellate Tribunal, which issued a decision in the Company's favor on April 15, 2015, finding, consistent with precedent from the Bombay High Court, that no income tax obligation arose as a result of the issuance of share capital. The tax authority has the right to appeal this decision in accordance with applicable Indian law.

14. Acquisitions and Other Transactions

The estimates of the fair value of the assets or rights acquired and liabilities assumed at the date of the applicable acquisition are subject to adjustment during the measurement period (up to one year from the particular acquisition date). The primary areas of the accounting for the acquisitions that are not yet finalized relate to the fair value of certain tangible and intangible assets acquired and liabilities assumed, including contingent consideration, residual goodwill and any related tax impact. The fair value of these net assets acquired are based on management's estimates and assumptions, as well as other information compiled by management, including valuations that utilize customary valuation procedures and techniques. While the Company believes that such preliminary estimates provide a reasonable basis for estimating the fair value of assets acquired and liabilities assumed, it evaluates any necessary information prior to finalization of the fair value. During the measurement period, the Company will adjust assets or liabilities if new information is obtained about facts and

Table of Contents

AMERICAN TOWER CORPORATION AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

circumstances that existed as of the acquisition date that, if known, would have resulted in the revised estimated values of those assets or liabilities as of that date. The effect of measurement period adjustments to the estimated fair value is reflected as if the adjustments had been completed on the acquisition date. The impact of all changes that do not qualify as measurement period adjustments are included in current period earnings. If the actual results differ from the estimates and judgments used in these fair values, the amounts recorded in the condensed consolidated financial statements could be subject to a possible impairment of the intangible assets or goodwill, or require acceleration of the amortization expense of intangible assets in subsequent periods. During the six months ended June 30, 2015, the Company made certain measurement period adjustments related to several acquisitions consummated in 2014 and therefore retrospectively adjusted the fair value of the assets acquired and liabilities assumed in the condensed consolidated balance sheet as of December 31, 2014.

Impact of current year acquisitions -The Company typically acquires communications sites from wireless carriers or other tower operators and subsequently integrates those sites into its existing portfolio of communications sites. The financial results of the Company's acquisitions have been included in the Company's condensed consolidated statements of operations for the three and six months ended June 30, 2015 from the date of the respective acquisition. The date of acquisition, and by extension the point at which the Company begins to recognize the results of an acquisition, may be dependent upon, among other things, the receipt of contractual consents, the commencement and extent of leasing arrangements and the timing of the transfer of title or rights to the assets, which may be accomplished in phases. Sites acquired from communications service providers may never have been operated as a business and may have been utilized solely by the seller as a component of its network infrastructure. An acquisition, depending on its size and nature, may or may not involve the transfer of business operations or employees.

The estimated aggregate impact of the 2015 acquisitions and the Verizon Transaction on the Company's revenues and gross margin for the three months ended June 30, 2015 was approximately $111.8 million and $54.0 million, respectively, and the estimated aggregate impact for the six months ended June 30, 2015 was approximately $116.3 million and $56.1 million, respectively. The revenues and gross margin amounts also reflect incremental revenues from the addition of new tenants to such sites subsequent to the transaction date. Incremental amounts of segment selling, general, administrative and development expense have not been reflected, as the amounts attributable to transactions are not comparable.

For those acquisitions accounted for as business combinations, the Company recognizes acquisition and merger related expenses in the period in which they are incurred and services are received. Acquisition and merger related expenses may include finder's fees, advisory, legal, accounting, valuation and other professional or consulting fees, fair value adjustments to contingent consideration and general administrative costs directly related to the transaction. Integration costs include incremental and non-recurring costs necessary to convert data, retain employees and otherwise enable the Company to operate new businesses efficiently. The Company records acquisition and merger related expenses, as well as integration costs, in Other operating expenses in the condensed consolidated statements of operations.

During the three and six months ended June 30, 2015 and 2014, the Company recorded the following acquisition and merger related expenses and integration costs (in thousands):


	Three Months Ended June 30,				Six Months Ended June 30,
	2015		2014		2015		2014
Acquisition and merger related expenses (1)	$	5,021	$	4,854	$	7,987	$	14,606
Integration costs	$	4,525	$	3,217	$	6,280	$	5,686

(1)	Acquisition and merger related expenses for the six months ended June 30, 2015 do not reflect approximately $9.9 million of transaction costs related to the Verizon Transaction as these costs have been capitalized as part of the assets' fair value.

Verizon Transaction

On March 27, 2015, the Company completed its acquisition of the exclusive right to lease, acquire or otherwise operate and manage 11,448 wireless communications sites from Verizon for approximately $5.053 billion in cash pursuant to the Master Agreement entered into on February 5, 2015 and the related Master Prepaid Lease, Management Agreement, Sale Site Master Lease Agreement and MPL Site Master Lease Agreement, subject to certain post-closing adjustments.

The Company, through its wholly-owned subsidiary, leased or subleased from certain Verizon subsidiaries 11,285 communications sites, including the interest in the land, the tower and certain related improvements and tower related assets pursuant to the Master Prepaid Lease. Under the Master Prepaid Lease, the Company has the exclusive right to lease and operate the Verizon communications sites for a weighted average term of approximately 28 years and the Company will have the option to purchase the communications sites in various tranches at the end of the respective lease or sublease terms at a fixed amount stated in the sublease for such tranche plus the fair market value of certain alterations made to the related towers. The Company accounted for the payment with respect to the leased sites as a capital lease and the respective lease and non-lease elements related to tower assets and intangible assets, as described below. The total consideration allocated to this element of the overall transaction was $4.964 billion, which included approximately $9.9 million of transaction costs.

In addition, the Company, through its wholly-owned subsidiary, acquired 163 additional communications sites. The Company accounted for these sites as a business combination and the purchase price of $99.0 million is reflected below in "2015 Acquisitions."

Upon closing, the Company agreed to lease, sublease or otherwise make available collocation space at each of the communications sites to Verizon for an initial non-cancellable term of ten years, subject to automatic extension for eight additional five-year renewal terms. The initial collocation rent is $1,900 per month for each communications site, with annual rent increases of 2%.

The Company funded the Verizon Transaction with (i) proceeds from its concurrent registered public offerings of its common stock and Series B Preferred Stock, (ii) borrowings under the Company's revolving credit facilities and (iii) cash on hand.

The Company included the Verizon Transaction in the unaudited pro forma financial results included herein as if the capital lease began on January 1, 2014. Management relied on various estimates and assumptions due to the fact that Verizon did not operate the sites as a business and the sites were utilized primarily by Verizon as a component of its network infrastructure.

The following table summarizes the allocation of consideration transferred for the 11,285 communications sites under the Master Prepaid Lease (in thousands). Balances are reflected in the accompanying condensed consolidated balance sheets as of June 30, 2015 and represent the asset balances of the capital lease.

Pro Forma Consolidated Results

The following table presents the unaudited pro forma financial results as if the 2015 acquisitions, as well as the Verizon Transaction described above, had occurred on January 1, 2014 and the 2014 acquisitions had occurred on January 1, 2013 (in thousands, except per share data). The pro forma consolidated results do not reflect the impact of the acquisition in Nigeria described in note 16. Management relied on various estimates and assumptions due to the fact that some of the transactions never operated as a business and were utilized solely by the seller as a component of their network infrastructure. As a result, historical operating results may not be available. The pro forma results do not include any anticipated cost synergies, costs or other integration impacts. Accordingly, such pro forma amounts are not necessarily indicative of the results that actually would have occurred had the transactions been completed on the dates indicated, nor are they indicative of the future operating results of the Company.

Acquisition-Related Contingent Consideration

The Company may be required to pay additional consideration under certain agreements for the acquisition of communications sites if specific conditions are met or events occur. In Colombia and Ghana, the Company may be required to pay additional consideration upon the conversion of certain barter agreements with other wireless carriers to cash-paying lease agreements. In Costa Rica and the United States, the Company may be required to pay additional consideration if certain pre-designated tenant leases commence during a specified period of time.

A summary of the value of the Company's contingent consideration is as follows (in thousands):

15. Business Segments

The Company operates its business in three reportable segments, (i) domestic rental and management, (ii) international rental and management and (iii) network development services. The Company's primary business is leasing space on multitenant communications sites to wireless service providers, radio and television broadcast companies, wireless data providers, government agencies and municipalities and tenants in a number of other industries. This business is referred to as the Company's rental and management operations and is comprised of domestic and international segments, which, as of June 30, 2015, consisted of the following:

•

Domestic: rental and management operations in the United States; and

•

International: rental and management operations in Brazil, Chile, Colombia, Costa Rica, Germany, Ghana, India, Mexico, Nigeria, Peru, South Africa and Uganda.

The Company has applied the aggregation criteria to operations within the international rental and management operating segments on a basis consistent with management's review of information and performance evaluation.

The Company's network development services segment offers tower-related services in the United States, including site acquisition, zoning and permitting services and structural analysis services, which primarily support its site leasing business and the addition of new tenants and equipment on its sites. The network development services segment is a strategic business unit that offers different services from the rental and management operating segments and requires different resources, skill sets and marketing strategies.

The accounting policies applied in compiling segment information below are similar to those described in note 1 to the Company's consolidated financial statements included in the 2014 Form 10-K. Among other factors, in evaluating financial performance in each business segment, management uses segment gross margin and segment operating profit. The Company defines segment gross margin as segment revenue less segment operating expenses excluding stock-based compensation expense recorded in costs of operations; 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 international rental and management segment gross margin and segment operating profit also include Interest income, TV Azteca, net. These measures of segment gross margin and segment operating profit are also before Interest income, Interest expense, Gain (loss) on retirement of long-term obligations, Other income (expense), Net income (loss) attributable to noncontrolling interest, Income (loss) on equity method investments and Income tax benefit (provision). The categories of expenses indicated above, such as depreciation, have been excluded from segment operating performance as they are not considered in the review of information or the evaluation of results by management. There are no significant revenues resulting from transactions between the Company's operating segments. All intercompany transactions are eliminated to reconcile segment results and assets to the condensed consolidated statements of operations and condensed consolidated balance sheets.

Summarized financial information concerning the Company's reportable segments for the three and six months ended June 30, 2015 and 2014 is shown in the following tables. The "Other" column (i) represents amounts excluded from specific segments, such as business development operations, stock-based compensation expense and corporate expenses included in Selling, general, administrative and development expense; Other

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," "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 I, Item 1A. of our Annual Report on Form 10-K for the year ended December 31, 2014 (the "2014 Form 10-K"). 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 assumptions 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 from these estimates and such differences could be material to the financial statements. 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" of the 2014 Form 10-K, and 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 one of the largest global real estate investment trusts and a leading independent owner, operator and developer of multitenant communications real estate. Our primary business is the leasing of space on multitenant communications sites to wireless service providers, radio and television broadcast companies, wireless data providers, government agencies and municipalities and tenants in a number of other industries. In addition to the communications sites in our portfolio, we manage rooftop and tower sites for property owners under various contractual arrangements. We also hold property interests that we lease to communications service providers and third-party tower operators. We refer to this business as our rental and management operations, which accounted for approximately 98% of our total revenues for the six months ended June 30, 2015 and includes our domestic rental and management segment and our international rental and management segment. Through our network development services we offer tower-related services domestically, including site acquisition, zoning and permitting services and structural analysis services, which primarily support our site leasing business and the addition of new tenants and equipment on our sites, including in connection with provider network upgrades. We operate as a real estate investment trust for U.S. federal income tax purposes ("REIT").

On March 27, 2015, we significantly expanded our domestic portfolio by obtaining the exclusive right to lease, acquire or otherwise operate and manage 11,448 wireless communications sites from Verizon Communications Inc. ("Verizon") in the United States (the "Verizon Transaction"). On July 1, 2015, we expanded our international footprint by acquiring 4,699 communications sites in Nigeria. Our communications real estate portfolio of 92,729 sites as of June 30, 2015, included 40,064 communications towers domestically, 52,211 communications towers internationally and 454 distributed antenna system ("DAS") networks, which provide seamless coverage solutions in certain in-building and outdoor wireless environments. Our portfolio primarily consists of towers that we own and towers that we operate pursuant to long-term lease arrangements.

(1)	All of the communications sites we operate are held pursuant to long-term capital leases, including those subject to purchase options.

We operate in three reportable segments: domestic rental and management, international rental and management and network development services. In evaluating operating performance in each business segment, management uses, among other factors, segment gross margin and segment operating profit (see note 15 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, Gain (loss) on retirement of long-term obligations, Other income (expense), Net income (loss) attributable to noncontrolling interest, Income (loss) on equity method investments and Income tax benefit (provision).

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 results of operations, financial position and sources and uses of liquidity. In addition, we highlight key trends, which management believes provide valuable insight into our operating and financial resource allocation decisions.

Revenue Growth . The primary factors affecting the revenue growth of our domestic and international rental and management segments are:

•

Recurring organic revenue from tenant leases attributable to sites that existed in our portfolio as of the beginning of the prior year period ("legacy sites");

•

Contractual rent escalations on existing tenant leases, net of cancellations;

•

New revenue attributable to leasing additional space on our legacy sites; and

•

New revenue attributable to sites acquired or constructed since the beginning of the prior year period ("new sites").

Due to our diversified communications site portfolio, our tenant lease rates vary considerably depending upon numerous factors, including, but not limited to, amount and type of tenant equipment on the tower, ground space required by the tenant, remaining tower capacity and tower location. We measure the remaining tower capacity by assessing several factors, including tower height, tower type, environmental conditions, existing equipment on the tower and zoning and permitting regulations in effect in the jurisdiction where the tower is located. In many instances, tower capacity can be increased through tower augmentation.

Table of Contents

The majority of our tenant leases with wireless carriers have an initial non-cancellable term of ten years, with multiple renewal terms. Accordingly, nearly all of the revenue generated by our rental and management operations during the six months ended June 30, 2015 was recurring revenue that we should continue to receive in future periods. Based upon foreign currency exchange rates and the tenant leases in place as of June 30, 2015, we expect to generate approximately $29 billion of non-cancellable tenant lease revenue over future periods, absent the impact of straight-line lease accounting. This expected revenue includes the impact of the tenant leases we entered into or assumed in connection with the Verizon Transaction. Most of our tenant leases have provisions that periodically increase the rent due under the lease, typically annually based on a fixed escalation (approximately 3% in the United States) or an inflationary index in our international markets, or a combination of both. In addition, certain of our tenant leases provide for additional revenue to cover costs, such as ground rent or power and fuel costs.

Revenue lost from either cancellations of leases at the end of their terms or rent negotiations historically has not had a material adverse effect on the revenues generated by our rental and management operations. During the six months ended June 30, 2015, loss of revenue from tenant lease cancellations or renegotiations represented approximately 2% of our rental and management operations revenues.

Demand Drivers . 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 the corresponding incremental demand for our wireless real estate. By adding new tenants and new equipment for existing tenants on our sites, we are able to increase these sites' utilization and profitability. We believe the majority of our site leasing activity will continue to come from wireless service providers. Our legacy site portfolio and our established tenant base provide us with new business opportunities, which have historically resulted in consistent and predictable organic revenue growth as wireless carriers seek to increase the coverage and capacity of their existing networks, while also deploying next generation wireless technologies. In addition, we intend to continue to supplement the organic growth on our legacy sites by selectively developing or acquiring new sites in our existing and new markets where we can achieve our risk adjusted return on investment objectives. In a majority of our international markets, revenue also includes the reimbursement of direct costs such as ground rent or power and fuel costs.

Based on industry research and projections, we expect the following key industry trends will result in incremental revenue opportunities for us:

•

Subscribers' use of wireless data continues to grow rapidly given increasing smartphone and other advanced device penetration, the proliferation of bandwidth-intensive applications on these devices and the continuing evolution of the mobile ecosystem. We believe carriers will be compelled to deploy additional equipment on existing networks while also rolling out more advanced wireless networks to address coverage and capacity needs resulting from this increasing wireless data usage.

•

The deployment of advanced wireless technology across existing wireless networks will provide higher speed data services and further enable fixed broadband substitution. As a result, we expect our tenants to continue deploying additional equipment across their existing networks.

•

Wireless service providers compete based on the quality of their existing wireless networks, which is driven by capacity and coverage. To maintain or improve their network performance as overall network usage increases, our tenants continue deploying additional equipment across their existing sites while also adding new cell sites. We anticipate increasing network densification over the next several years, as existing network infrastructure is anticipated to be insufficient to account for rapidly increasing levels of wireless data usage.

•

Wireless service providers continue to acquire additional spectrum, and as a result are expected to add additional sites and equipment to their network as they seek to optimize their network configuration.

As part of our international expansion initiatives, we have targeted markets in various stages of network development to diversify our international exposure and position us to benefit from a number of different

Table of Contents

wireless technology deployments over the long term. In addition, we have focused on building relationships with large multinational carriers such as Bharti Airtel Limited, MTN Group Limited, Telefónica S.A. and Vodafone Group PLC. We believe that consistent carrier investments in their networks across our international markets position us to generate meaningful organic revenue growth going forward.

In emerging markets, such as Ghana, India, Nigeria and Uganda, wireless networks tend to be significantly less advanced than those in the United States, and initial voice networks continue to be deployed in underdeveloped areas. A majority of consumers in these markets still utilize basic wireless services, predominantly on feature phones, and advanced device penetration remains low. In more developed urban locations within these markets, early-stage data network deployments are underway. Carriers are focused on completing voice network build-outs while also investing in initial data networks as wireless data usage and smartphone penetration within their customer bases begin to accelerate.

In markets with rapidly evolving network technology, such as South Africa and most of the countries in Latin America where we do business, initial voice networks, for the most part, have already been built out, and carriers are focused on third generation (3G) network build outs, with select investments in fourth generation (4G) technology. Consumers in these regions are increasingly adopting smartphones and other advanced devices, and as a result, the usage of bandwidth-intensive mobile applications is growing materially. Recent spectrum auctions in these rapidly evolving markets have allowed incumbent carriers to accelerate their data network deployments and have also enabled new entrants to begin initial investments in data networks. Smartphone penetration and wireless data usage in these markets are growing rapidly, which mandates that carriers continue to invest in their networks in order to maintain and augment their quality of service.

Finally, in markets with more mature network technology, such as Germany, carriers are focused on deploying 4G data networks to account for rapidly increasing wireless data usage amongst their customer base. With higher smartphone and advanced device penetration and significantly higher per capita data usage, carrier investment in networks is focused on 4G coverage and capacity.

We believe that the network technology migration we have seen in the United States, which has led to significantly denser networks and meaningful new business commencements for us over a number of years, will ultimately be replicated in our less advanced international markets. As a result, we expect to be able to leverage our extensive international portfolio of over 52,000 communications sites and the relationships we have built with our carrier customers to drive sustainable, long-term growth.

Rental and Management Operations Expenses . Direct operating expenses incurred by our domestic and international rental and management segments include direct site level expenses and consist primarily of ground rent and power and fuel costs, some of which may be passed through to our tenants, as well as property taxes, repairs and maintenance. These segment direct operating expenses exclude all segment and corporate selling, general, administrative and development expenses, which are aggregated into one line item entitled Selling, general, administrative and development expense in our condensed consolidated statements of operations. In general, our domestic and international rental and management segments' selling, general, administrative and development expenses do not significantly increase as a result of adding incremental tenants to our legacy sites and typically increase only modestly year-over-year. As a result, leasing additional space to new tenants on our legacy sites provides significant incremental cash flow. We may, however, incur additional segment selling, general, administrative and development expenses as we increase our presence in geographic areas where we have launched operations or are focused on expanding our portfolio. Our profit margin growth is therefore positively impacted by the addition of new tenants to our legacy sites and can be temporarily diluted by our development activities.

Network Development Services Segment Revenue Growth . As we continue to focus on growing our rental and management operations, we anticipate that our network development services revenue will continue to represent a small percentage of our total revenues.

Non-GAAP Financial Measures

Included in our analysis of our results of operations are discussions regarding earnings before interest, taxes, depreciation, amortization and accretion, as adjusted ("Adjusted EBITDA"), Funds From Operations, as defined by the National Association of Real Estate Investment Trusts ("NAREIT FFO") and Adjusted Funds From Operations ("AFFO").

We define Adjusted EBITDA as Net income before Income (loss) on discontinued operations, net; Income (loss) on equity method investments; Income tax benefit (provision); Other income (expense); Gain (loss) on retirement of long-term obligations; Interest expense; Interest income; Other operating income (expense); Depreciation, amortization and accretion; and stock-based compensation expense.

NAREIT FFO is defined as net income before gains or losses from the sale or disposal of real estate, real estate related impairment charges, real estate related depreciation, amortization and accretion and dividends on preferred stock, and including adjustments for (i) unconsolidated affiliates and (ii) noncontrolling interest.

We define AFFO as NAREIT FFO before (i) straight-line revenue and expense; (ii) stock-based compensation expense; (iii) the non-cash portion of our tax provision; (iv) non-real estate related depreciation, amortization and accretion; (v) amortization of deferred financing costs, capitalized interest, debt discounts and premiums and long-term deferred interest charges; (vi) other income (expense); (vii) gain (loss) on retirement of long-term obligations; (viii) other operating income (expense); and adjustments for (ix) unconsolidated affiliates and (x) noncontrolling interest, less cash payments related to capital improvements and cash payments related to corporate capital expenditures.

Adjusted EBITDA, NAREIT FFO and AFFO are not intended to replace net income or any other performance measures determined in accordance with GAAP. Neither NAREIT FFO nor AFFO represent cash flows from operating activities in accordance with GAAP and, therefore, these measures should not be considered indicative of cash flows from operating activities as a measure of liquidity or of funds available to fund our cash needs, including our ability to make cash distributions.

Our measurement of Adjusted EBITDA, NAREIT FFO and AFFO may not, however, be fully comparable to similarly titled measures used by other companies. Reconciliations of Adjusted EBITDA, NAREIT FFO and AFFO to net income, the most directly comparable GAAP measure, have been included below.

For more information regarding these measures, see "Non-GAAP Financial Measures" under Item 7 "Management's Discussion and Analysis of Financial Condition and Results of Operations" of the 2014 Form 10-K.

Effective tax rate		8.2	%		9.0	%								9.7	%		8.7	%

The decrease in the effective tax rate ("ETR") for the three months ended June 30, 2015 was primarily attributable to the impact of one-time uncertain tax positions recorded during the three months ended June 30, 2014, partially offset by the impact of early retirement of long-term obligations recorded during the three months ended June 30, 2015.

The increase in ETR for the six months ended June 30, 2015 was primarily attributable to the impact of foreign currency translation and the impact of early retirement of long-term obligations recorded during the six months ended June 30, 2015. The increase was partially offset by one-time uncertain tax positions recorded during the six months ended June 30, 2014.

In 2013, we acquired MIP Tower Holdings LLC ("MIPT"), which had been organized and qualified as a REIT. We intend to file a tax election pursuant to which MIPT will no longer operate as a separate REIT

Table of Contents

for federal and state income tax purposes, effective July 25, 2015. In connection with this election, we expect to incur a one-time cash tax charge of approximately $92.5 million, based on preliminary calculations, in the second half of 2015.

As a REIT, we may deduct earnings distributed to stockholders against the income generated in our qualified REIT subsidiaries or other disregarded entities of a REIT (collectively, "QRSs"). In addition, we are able to offset income in certain taxable REIT subsidiaries ("TRSs") and our QRSs by utilizing our net operating losses ("NOLs"), subject to specified limitations.

The ETR on income from continuing operations for the three and six months ended June 30, 2015 and 2014 differs from the federal statutory rate primarily due to our qualification for taxation as a REIT and adjustments for foreign items.

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 or equity offerings.

The following table summarizes our liquidity as of June 30, 2015 (in thousands):


Available under our 2013 credit facility	$	2,500,000
Available under our 2014 credit facility		20,000
Letters of credit		(10,752	)

Total available under credit facilities, net		2,509,248
Cash and cash equivalents		274,702

Total liquidity	$	2,783,950

In July 2015, we borrowed an additional $850.0 million under our multi-currency senior unsecured revolving credit facility entered into in June 2013, as amended (the "2013 Credit Facility"), which we primarily used to fund our acquisition in Nigeria.

Summary cash flow information for the six months ended June 30, 2015 and 2014 is set forth below (in thousands).

We use our cash flows to fund our operations and investments in our business, including tower maintenance and improvements, communications site construction and managed network installations and tower and land acquisitions. Additionally, we use our cash flows to make distributions, including distributions of our REIT taxable income to maintain our qualification for taxation as a REIT under the Internal Revenue Code of 1986, as amended. We may also repay or repurchase our existing indebtedness from time to time. We typically fund our international expansion efforts primarily through a combination of cash on hand, intercompany debt and equity contributions. We intend to file a tax election pursuant to which MIPT will no longer operate as a separate REIT for federal and state income tax purposes, effective July 25, 2015 (see note 9 to our condensed consolidated financial statements included herein). In connection with this election, we expect to pay incremental cash taxes of approximately $92.5 million, based on preliminary calculations, in the second half of 2015.

As of June 30, 2015, we had total outstanding indebtedness of approximately $16.2 billion, with a current portion of $38.8 million. During the six months ended June 30, 2015, we generated sufficient cash flow from operations and financing activities to fund our capital expenditures and debt service obligations, as well as our required REIT distributions. We believe the cash generated by operating activities during the year ending December 31, 2015, together with our borrowing capacity under our credit facilities, will be sufficient to fund our required distributions, capital expenditures, debt service obligations (interest and principal repayments) and signed acquisitions. As of June 30, 2015, we had approximately $167.1 million of cash and cash equivalents held by our foreign subsidiaries, of which $55.9 million was held by our joint ventures. Historically, it has not been

Table of Contents

our practice to repatriate cash from our foreign subsidiaries primarily due to our ongoing expansion efforts and related capital needs. However, in the event that we do repatriate any funds, we may be required to accrue and pay taxes.

Cash Flows from Operating Activities

The $35.9 million decrease in cash provided by operating activities for the six months ended June 30, 2015 was primarily due to negative working capital items and higher cash interest costs, which have offset our year to date growth in Adjusted EBITDA of approximately $163.3 million. The primary factors impacting the decrease in cash provided by operating activities as compared to the six months ended June 30, 2014, include:

•

A decrease due to the non-recurrence of a 2014 value added tax refund of approximately $60.3 million;

•

A decrease in domestic capital contributions and tenant settlements received of approximately $51.5 million;

•

An increase of approximately $20.8 million in cash paid for interest; and

•

An increase of approximately $32.0 million in prepaid assets, primarily related to costs associated with our land lease management program.

Cash Flows from Investing Activities

Our significant investing activities during the six months ended June 30, 2015 are highlighted below:

•

We spent $5.060 billion, including approximately $7.1 million of transaction costs, for the Verizon Transaction.

•

We spent approximately $644.3 million for the acquisition of 4,176 communications sites from TIM Celular S.A. ("TIM").

•

We spent $311.1 million for purchases of property and equipment and construction activities, including (i) $128.7 million of capital expenditures for discretionary capital projects, such as completion of the construction of approximately 1,588 communications sites and the installation of approximately eight shared generators domestically, (ii) $58.2 million spent to acquire land under our towers that was subject to ground agreements (including leases), (iii) $42.2 million of capital expenditures related to capital improvements primarily attributable to our communications sites and corporate capital expenditures primarily attributable to information technology improvements, (iv) $67.6 million for the redevelopment of existing communications sites to accommodate new tenant equipment and (v) $14.4 million of capital expenditures related to start-up capital projects primarily attributable to acquisitions and new market launches and costs that are contemplated in the business cases for these investments.

We plan to continue to allocate our available capital, after satisfying our distribution requirements, among investment alternatives that meet our return on investment criteria. Accordingly, we expect to continue to deploy our capital through our annual capital expenditure program, including land purchases and new site construction, and through acquisitions. We expect that our 2015 total capital expenditures will be between $770 million and $870 million, as follows (in millions):


Discretionary capital projects (1)	$	275	to	$	315
Ground lease purchases		150	to		170
Capital improvements and corporate expenditures		105	to		115
Redevelopment		155	to		175
Start-up capital projects		85	to		95

Total capital expenditures	$	770	to	$	870

(1)	Includes the construction of approximately 2,750 to 3,250 communications sites.

Refinancing of GTP Acquisition Partners Securitization . On May 29, 2015, GTP Acquisition Partners I, LLC ("GTP Acquisition Partners"), one of our wholly owned subsidiaries, repaid all amounts outstanding under the Existing GTP AP Notes, plus prepayment consideration and other costs and expenses related thereto, with cash on hand and proceeds from a private issuance (the "2015 Securitization") of $350.0 million of American Tower Secured Revenue Notes, Series 2015-1, Class A (the "Series 2015-1 Notes") and $525.0 million of American Tower Secured Revenue Notes, Series 2015-2, Class A (the "Series 2015-2 Notes," and together with the Series 2015-1 Notes, the "2015 Notes"). The 2015 Notes were issued by GTP Acquisition Partners pursuant to a Third Amended and Restated Indenture and related series supplements, each dated as of May 29, 2015 (collectively, the "Indenture"), between GTP Acquisition Partners and its subsidiaries (the "GTP Entities") and The Bank of New York Mellon, as trustee. The Series 2015-1 Notes have an interest rate of 2.350%, an anticipated repayment date of June 15, 2020 and a final repayment date of June 15, 2045. The Series 2015-2 Notes have an interest rate of 3.482%, an anticipated repayment date of June 16, 2025 and a final repayment date of June 15, 2050.

The 2015 Notes may be prepaid in whole or in part at any time, provided such payment is accompanied by the applicable prepayment consideration. If prepayment occurs within 12 months of the anticipated repayment date with respect to the Series 2015-1 Notes, or 18 months of the anticipated repayment date with respect to the Series 2015-2 Notes, no prepayment consideration is due. If the Series 2015-1 Notes or the Series 2015-2 Notes have not been repaid in full on the applicable anticipated repayment date, additional interest will accrue on the unpaid principal balance of the applicable series of the 2015 Notes and such series will begin to amortize on a monthly basis from excess cash flow.

Each redemption was funded with borrowings under our existing credit facilities and cash on hand. Upon completion of these redemptions, none of the 4.625% Notes or the 7.000% Notes remained outstanding.

2.800% Senior Notes and 4.000% Senior Notes Offering . On May 7, 2015, we completed a registered public offering of $750.0 million aggregate principal amount of 2.800% senior unsecured notes due 2020 (the "2.800%

Table of Contents

Notes") and $750.0 million aggregate principal amount of 4.000% senior unsecured notes due 2025 (the "4.000% Notes"). The net proceeds from this offering were approximately $1,480.1 million, after deducting commissions and estimated expenses. We used the proceeds to repay existing indebtedness under the 2013 Credit Facility.

We may redeem the notes at any time, in whole or in part, at the applicable redemption price. If we redeem the 2.800% Notes prior to May 1, 2020 or the 4.000% Notes prior to March 1, 2025, we will pay a redemption price equal to 100% of the principal amount of the notes plus a make-whole premium, together with accrued interest to the redemption date. If we redeem the 2.800% Notes on or after May 1, 2020 or the 4.000% Notes on or after March 1, 2025, we will not be required to pay a make-whole premium. In addition, if we undergo a change of control and ratings decline, each as defined in the supplemental indenture, we may be required to repurchase all of the notes at a purchase price equal to 101% of the principal amount of the notes, plus accrued and unpaid interest (including additional interest, if any), up to but not including the repurchase date. The 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 supplemental indenture contains certain covenants that restrict our ability to merge, consolidate or sell assets and our (together with our subsidiaries') ability 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 supplemental indenture.

Sales of Equity Securities. We receive proceeds from sales of our equity securities pursuant to our employee stock purchase plan (the "ESPP") and upon exercise of stock options granted under our equity incentive plans. For the six months ended June 30, 2015, we received an aggregate of $17.4 million in proceeds upon exercises of stock options and from the ESPP.

Distributions. As a REIT, we must annually distribute to our stockholders an amount equal to at least 90% of our REIT taxable income (determined before the deduction for distributed earnings and excluding any net capital gain). Generally, we have distributed, and expect to continue to distribute all or substantially all of our REIT taxable income after taking into consideration our utilization of NOLs. Since our conversion to a REIT in 2012, we have distributed an aggregate of approximately $1.7 billion to our common stockholders, primarily subject to taxation as ordinary income.

The amount, timing and frequency of future distributions will be at the sole discretion of our Board of Directors and will be declared based upon various factors, a number of which may be beyond our control, including our financial condition and operating cash flows, the amount required to maintain our qualification for taxation as a REIT and reduce any income and excise taxes that we otherwise would be required to pay, limitations on distributions in our existing and future debt and preferred equity instruments, our ability to utilize NOLs to offset our distribution requirements, limitations on our ability to fund distributions using cash generated through our TRSs and other factors that our Board of Directors may deem relevant.

We have two series of preferred stock outstanding, 5.25% Mandatory Convertible Preferred Stock, Series A with a dividend rate of 5.25% and the Series B Preferred Stock, with a dividend rate of 5.50%. Dividends are payable quarterly in arrears, subject to declaration by our Board of Directors.

During the six months ended June 30, 2015, we paid $1.3125 per share, or $7.9 million, to Series A preferred stockholders of record at the close of business on each of February 1, 2015 and May 1, 2015. During the six months ended June 30, 2015, we paid $11.1528 per share, or $15.3 million, to Series B preferred stockholders of record at the close of business on May 1, 2015.

In addition, in July 2015, we declared dividends of $1.3125 per share, or $7.9 million, payable on August 17, 2015 to Series A preferred stockholders of record at the close of business on August 1, 2015 and $13.75 per share, or $18.9 million, payable on August 17, 2015 to Series B preferred stockholders of record at the close of business on August 1, 2015.

As of June 30, 2015, the amount accrued for distributions payable related to unvested restricted stock units was $3.6 million. During the six months ended June 30, 2015, we paid $1.2 million of distributions upon the vesting of restricted stock units.

Additional information regarding 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 $25.0 million as Other non-current liabilities in the condensed consolidated balance sheet as of June 30, 2015. We also classified $24.5 million of accrued income tax related interest and penalties as Other non-current liabilities in the condensed consolidated balance sheet as of June 30, 2015.

Factors Affecting Sources of Liquidity

As discussed in the "Liquidity and Capital Resources" section of the 2014 Form 10-K, our liquidity is dependent on our ability to generate cash flow from operating activities, borrow funds under our credit facilities and maintain compliance with the contractual agreements governing our indebtedness. We believe that the debt agreements discussed below represent our material debt agreements that contain covenants, our 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 Agreements Relating to Our Credit Facilities . The loan agreements for the 2014 Credit Facility, the 2013 Credit Facility and the 2013 Term Loan contain certain financial and operating covenants and other restrictions applicable to us and our subsidiaries that are not designated as unrestricted subsidiaries on a consolidated basis. These include limitations on additional debt, distributions and dividends, guaranties, sales of assets and liens. The loan agreements also contain covenants that establish three financial maintenance tests with which we and our restricted subsidiaries must comply related to (i) total leverage,

Table of Contents

(ii) senior secured leverage and (iii) in the event that our debt ratings fall below investment grade, interest coverage, as set forth in the table below. As of June 30, 2015, we were in compliance with each of these covenants.


		Compliance Tests For 12 Months Ended June 30, 2015 ($ in billions)
	Ratio (1)	Additional Debt/Interest Expense Capacity Under Covenants (2)			Capacity for Adjusted EBITDA Decrease Under Covenants (3)
Consolidated Total Leverage Ratio	Total Debt to Adjusted EBITDA £ 7.25:1.00 (4)		~ $5.8			~ $0.8

Consolidated Senior Secured Leverage Ratio	Senior Secured Debt to Adjusted EBITDA £ 3.00:1.00		~ $5.6			~ $1.9

Interest Coverage Ratio (5)	Adjusted EBITDA to Interest Expense ³ 2.50:1.00		~ $0.6	(6)		~ $1.6

(1)	Each component of the ratio as defined in the applicable loan agreement.

(2)	Assumes no change to Adjusted EBITDA.

(3)	Assumes no change to our existing debt levels.

(4)	The required ratio will be £ 7.00:1.00 for the quarters ended September 30, 2015 and December 31, 2015 and £ 6.00:1.00 thereafter.

(5)	Applies in the event that our debt ratings fall below investment grade.

(6)	Our interest expense for the 12 months ended June 30, 2015 was approximately $571.1 million.

The loan agreements for our credit facilities also contain 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 certain other covenants of the loan agreements for our credit facilities would not only prevent us from being able to borrow additional funds under these credit facilities, but would constitute a default under these credit facilities, 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 may 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 agreements for these credit facilities and our ability to fund our debt service obligations. Based upon our current expectations, we believe our operating results during the next 12 months will be sufficient to comply with these covenants.

Restrictions Under Agreements Relating to the 2015 Securitization, the 2013 Securitization and 2012 GTP Notes . The Indenture related to the 2015 Securitization, the loan agreement (the "Loan Agreement") related to the 2013 Securitization and the indenture governing the Secured Tower Cellular Site Revenue Notes, Series 2012-1 and Series 2012-2 (the "2012 GTP Notes") issued by GTP Cellular Sites, LLC ("GTP Cellular Sites"), include certain financial ratios and operating covenants and other restrictions customary for transactions subject to rated securitizations. Among other things, GTP Acquisition Partners, American Tower Asset Sub, LLC and American Tower Asset Sub II, LLC (the "AMT Asset Subs") and GTP Cellular Sites are prohibited from incurring other indebtedness for borrowed money or further encumbering their assets subject to customary carve-outs for ordinary course trade payables and permitted encumbrances (as defined in the applicable agreement).

Table of Contents

Under the terms of the agreements, amounts due will be paid from the cash flows generated by the assets securing the 2015 Notes, the nonrecourse loan that secures the Secured Tower Revenue Securities, Series 2013-1A and Series 2013-2A issued in the 2013 Securitization (the "Loan") or the 2012 GTP Notes (as applicable), which must be deposited into certain reserve accounts, and thereafter distributed, solely pursuant to the terms of the applicable agreement. On a monthly basis, after payment of all required amounts under the applicable agreement, subject to the conditions described in the table below, the excess cash flows generated from the operation of such assets are released to GTP Acquisition Partners, the AMT Asset Subs or GTP Cellular Sites, as applicable, which can then be distributed to, and used by, us. As of June 30, 2015, $109.2 million held in such reserve accounts was classified as restricted cash.

In order to distribute any excess cash flow to us, GTP Acquisition Partners, the AMT Asset Subs and GTP Cellular Sites must maintain a specified debt service coverage ratio ("DSCR"), generally calculated as the ratio of the net cash flow (as defined in the applicable agreement) to the amount of interest, servicing fees and trustee fees required to be paid over the succeeding 12 months on the principal amount of the 2015 Notes, the Loan or the 2012 GTP Notes, as applicable, that will be outstanding on the payment date following such date of determination. During an "amortization period" all excess cash flow and any amounts then in the reserve accounts accumulated due to the existence of a Cash Trap DSCR condition would be applied to pay principal of the 2015 Notes, the Loan or the 2012 GTP Notes, as applicable, on each monthly payment date, and so would not be available for distribution to us. Further, additional interest will begin to accrue with respect to any series of the 2015 Notes, subclass of the Loan or series of the 2012 GTP Notes from and after the anticipated repayment date at a per annum rate determined in accordance with the applicable agreement.

(1)	Based on the net cash flow of the applicable issuer or borrower as of June 30, 2015 and the expenses payable over the next 12 months on the 2015 Notes, the Loan or the 2012 GTP Notes, as applicable.

(2)	A Cash Trap DSCR condition commences if the DSCR is equal to or below 1.30x. Once triggered, a Cash Trap DSCR condition continues to exist until the DSCR exceeds the Cash Trap DSCR for two consecutive calendar quarters.

(3)	An amortization period commences if the DSCR is equal to or below 1.15x (the "Minimum DSCR") at the end of any calendar quarter and continues to exist until the DSCR exceeds the Minimum DSCR for two consecutive calendar quarters.

(4)

No amortization period is triggered if the outstanding principal amount of a series has not been repaid in full on the applicable anticipated repayment date. However, in such event, additional interest will accrue on the unpaid principal balance of the applicable series, and such series will begin to amortize on a monthly basis from excess cash flow.

(5)	Includes amounts distributed pursuant to the Existing GTP AP Notes prior to the repayment on May 29, 2015.

(6)	An amortization period exists if the outstanding principal amount has not been paid in full on the applicable anticipated repayment date and continues to exist until such principal has been repaid in full.

(7)	A Cash Trap DSCR condition commences if the DSCR is equal to or below 1.30x. Once triggered, a Cash Trap DSCR condition continues to exist until the DSCR exceeds the Cash Trap DSCR for two consecutive calendar months.

(8)	An amortization period commences if the DSCR is equal to or below the Minimum DSCR at the end of any calendar month and continues to exist until the DSCR exceeds the Minimum DSCR for two consecutive calendar months.

A failure to meet the noted DSCR tests could prevent GTP Acquisition Partners, the AMT Asset Subs or GTP Cellular Sites from distributing excess cash flow to us, which could affect our ability to fund our capital expenditures, including tower construction and acquisitions, meet REIT distribution requirements and make preferred stock dividend payments. With respect to the 2015 Notes and the 2012 GTP Notes, upon occurrence and during an event of default, the applicable trustee may, in its discretion or at direction of holders of more than 50% of the aggregate outstanding principal of any series of the 2015 Notes or the 2012 GTP Notes, as applicable, declare such series of 2015 Notes or 2012 GTP Notes immediately due and payable, in which case any excess cash flow would need to be used to pay holders of such notes. Furthermore, if GTP Acquisition Partners, the AMT Asset Subs or GTP Cellular Sites were to default on a series of the 2015 Notes, the Loan or the 2012 GTP

Table of Contents

Notes, the applicable trustee may seek to foreclose upon or otherwise convert the ownership of all or any portion of the 3,621 Secured Sites, the 5,190 wireless and broadcast towers that secure the Loan or the 105 towers and 1,064 property interests that secure the 2012 GTP Notes, respectively, in which case we could lose such sites and the revenue associated with those assets.

As discussed above, we use our available liquidity and seek new sources of liquidity to repay or repurchase our outstanding indebtedness. In addition, in order to fund capital expenditures, future growth and expansion initiatives and satisfy our REIT distribution requirements, 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 capital expenditures, future growth and expansion initiatives, satisfy our REIT distribution requirements, pay preferred stock dividends or refinance our existing indebtedness.

In addition, our liquidity depends on our ability to generate cash flow from operating activities. As set forth under the caption "Risk Factors" in Item 1A of the 2014 Form 10-K, we derive a substantial portion of our revenues from a small number of tenants and, consequently, a failure by a significant tenant to perform its contractual obligations to us could adversely affect our cash flow and liquidity.

For more information regarding the terms of our outstanding indebtedness, please see note 8 to our consolidated financial statements included in the 2014 Form 10-K.

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 assumptions 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 long-lived assets, asset retirement obligations, revenue recognition, rent expense, stock-based compensation, income taxes and accounting for business combinations and acquisitions of assets, which we discussed in the 2014 Form 10-K. Management bases its estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying amounts 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 six months ended June 30, 2015. We have made no material changes to the critical accounting policies described in the 2014 Form 10-K.

Accounting Standards Update

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The following table provides information as of June 30, 2015 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. For interest rate swaps, the table presents notional principal amounts and a weighted-average interest rate (in thousands, except percentages).


Long-Term Debt	2015			2016			2017			2018			2019			Thereafter			Total			Fair Value

(1)	Based on rates effective as of June 30, 2015.

(2)	Represents the weighted average fixed rate of interest based on contractual notional amount as a percentage of total notional amounts.

Interest Rate Risk

We have entered into interest rate swap agreements to manage our exposure to variability in interest rates on debt in Colombia and South Africa. All of our interest rate swap agreements have been designated as cash flow hedges and have an aggregate notional amount of $72.3 million, interest rates ranging from 5.74% to 7.83% and expiration dates through April 2021.

Changes in interest rates can cause interest charges to fluctuate on our variable rate debt. Variable rate debt as of June 30, 2015, was comprised of $1,980.0 million under the 2014 Credit Facility, $250.0 million under the 2013 Credit Facility, $2,000.0 million under the 2013 Term Loan, $70.9 million under the Uganda loan, $33.7 million under the South African facility after giving effect to our interest rate swap agreements, $37.7 million under the Colombian credit facility after giving effect to our interest rate swap agreement, $105.8 million under the BR Towers debentures and $13.0 million under the Brazil credit facility. A 10% increase in current interest rates would result in an additional $4.0 million of interest expense for the six months ended June 30, 2015.

See Item 2 of this Quarterly Report on Form 10-Q under the caption "Management's Discussion and Analysis of Financial Condition and Results of Operations-Liquidity and Capital Resources" for more information regarding our liquidity.

Foreign Currency Risk

We are exposed to market risk from changes in foreign currency exchange rates primarily in connection with our foreign subsidiaries and joint ventures internationally. 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 equity as a component of AOCI. We may enter into additional foreign currency financial instruments in anticipation of future transactions in order to minimize the impact of foreign currency fluctuations. For the six months ended June 30, 2015, approximately 31% of our revenues and approximately 36% of our total operating expenses were denominated in foreign currencies.

Table of Contents

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 June 30, 2015. As of June 30, 2015, the analysis indicated that such an adverse movement would cause our revenues, operating results and cash flows to fluctuate by approximately 3%.

As of June 30, 2015, we have incurred intercompany debt, which is not considered to be permanently reinvested, and similar unaffiliated balances that were denominated in a currency other than the functional currency of the subsidiary in which it is recorded. As this debt had not been designated as being a long-term investment in nature, any changes in the foreign currency exchange rates will result in unrealized gains or losses, which will be included in our determination of net income. An adverse change of 10% in the underlying exchange rates of our unsettled intercompany debt and similar unaffiliated balances would result in approximately $53.7 million of unrealized gains or losses that would be included in Other expense in our condensed consolidated statements of operations for the six months ended June 30, 2015.

CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

We have established disclosure controls and procedures designed 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 were effective as of June 30, 2015 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 (as defined in Rule 13a-15(f) under the Exchange Act) during the three months ended June 30, 2015 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
