BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Business —American Tower Corporation (together with its subsidiaries, “ATC” or the “Company”) is 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 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 refers to this business as its property operations. Additionally, the Company offers tower-related services in the United States, which the Company refers to as its services operations. These services include site application, zoning and permitting (“AZP”) and structural analysis, which primarily support the Company’s site leasing business, including the addition of new tenants and equipment on its sites. The Company’s customers include its tenants, licensees and other payers. The Company’s portfolio primarily consists of towers that it owns and towers that it operates pursuant to long-term lease arrangements, as well as distributed antenna system (“DAS”) networks, which provide seamless coverage solutions in certain in-building and outdoor wireless environments. In addition to the communications sites in its portfolio, the Company manages rooftop and tower sites for property owners under various contractual arrangements. The Company also holds other telecommunications infrastructure, fiber and property interests that it leases primarily to communications service providers and third-party tower operators and holds a portfolio of highly interconnected data center facilities and related assets in the United States that the Company leases primarily to enterprises, network operators, cloud providers and supporting service providers. American Tower Corporation is a holding company that conducts its operations through its directly and indirectly owned subsidiaries and 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”). Accordingly, the Company generally is not required to pay U.S. federal income taxes on income generated by its REIT operations, including the income derived from leasing space on its towers and in its data centers, as it receives a dividends paid deduction for distributions to stockholders that generally offsets its REIT income and gains. However, the Company remains obligated to pay U.S. federal income taxes on earnings from its domestic taxable REIT subsidiaries (“TRSs”). In addition, the Company’s international assets and operations, regardless of their classification for U.S. tax purposes, continue to be subject to taxation in the jurisdictions where those assets are held or those operations are conducted. The use of TRSs enables the Company to continue to engage in certain businesses and jurisdictions while complying with REIT qualification requirements. The Company may, from time to time, change the election of previously designated TRSs to be included as part of the REIT. As of December 31, 2021, the Company’s REIT-qualified businesses included its U.S. tower leasing business, a majority of its U.S. indoor DAS networks business, its Services and Data Centers segments, as well as most of its operations in Canada, Costa Rica, France, Germany, Mexico and Nigeria. In January 2022, a majority of the Company’s operations in Ghana, Kenya, South Africa and Uganda became part of the REIT. Principles of Consolidation and Basis of Presentation —The accompanying 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 method or as investments in equity securities, depending upon the Company’s ability to exercise significant influence over operating and financial policies. All intercompany accounts and transactions have been eliminated. As of December 31, 2021, the Company holds (i) a 52% controlling interest in subsidiaries whose holdings consist of the Company’s operations in France, Germany, Poland and Spain (such subsidiaries collectively, “ATC Europe”) (Allianz and CDPQ (each as defined in note 16) hold the noncontrolling interests) and (ii) a 51% controlling interest in a joint venture whose holdings consist of the Company’s operations in Bangladesh (Confidence Tower Holdings Ltd. (“Confidence Group”) holds the noncontrolling interest). As of December 31, 2021, ATC Europe holds an 87% and an 83% controlling interest in subsidiaries that consist of the Company’s operations in Germany and Spain, respectively (PGGM holds the noncontrolling interests). See note 16 for a discussion of changes to the Company’s noncontrolling interests during the year ended December 31, 2021. Change in Reportable Segments —During the fourth quarter of 2021, as a result of the Company’s acquisition of CoreSite Realty Corporation (“CoreSite,” and the acquisition, the “CoreSite Acquisition”), the Company updated its reportable segments to add a Data Centers segment. The Data Centers segment is within the Company’s property operations. The Company will now report its results in seven segments – U.S. & Canada property (which includes all assets in the United States and Canada, other than the Company’s data center facilities and related assets), Asia-Pacific property, Africa property, Europe property, Latin America property, Data Centers and Services, which are discussed further in note 21. The change in reportable segments had no impact on the Company’s consolidated financial statements for any prior periods. Historical financial information included in this Annual Report on Form 10-K has not been adjusted as the amounts attributable to data center assets were insignificant as prior to the fourth quarter of 2021, the Company owned one data center. 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 consolidated financial statements and accompanying notes. Actual results may differ from those estimates, and such differences could be material to the accompanying consolidated financial statements. The significant estimates in the accompanying consolidated financial statements include impairment of long-lived assets (including goodwill), revenue recognition, rent expense and lease accounting, 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. Accounts Receivable and Deferred Rent Asset —The Company derives the largest portion of its revenues and corresponding accounts receivable and the related deferred rent asset from a relatively small number of customers in the telecommunications industry, and 52% of its current-year revenues are derived from three customers. The Company’s deferred rent asset is associated with non-cancellable tenant leases that contain fixed escalation clauses over the terms of the applicable lease in which revenue is recognized on a straight-line basis over the lease term. The Company mitigates its concentrations of credit risk with respect to notes and trade receivables and the related deferred rent assets by actively monitoring the creditworthiness of its borrowers and customers. In recognizing customer revenue, the Company assesses the collectibility of both the amounts billed and the portion recognized in advance of billing on a straight-line basis. This assessment takes customer credit risk and business and industry conditions into consideration to ultimately determine the collectibility of the amounts billed. To the extent the amounts, based on management’s estimates, may not be collectible, revenue recognition is deferred until such point as collectibility is determined to be reasonably assured. Any amounts that were previously recognized as revenue and are subsequently determined to present a risk of collection are reserved as bad debt expense included in Selling, general, administrative and development expense in the accompanying consolidated statements of operations. Accounts receivable is reported net of allowances for doubtful accounts related to estimated losses resulting from a customer’s inability to make required payments and allowances for amounts invoiced whose collectibility is not reasonably assured. These allowances are generally estimated based on payment patterns, days past due and collection history, and incorporate changes in economic conditions that may not be reflected in historical trends, such as customers in bankruptcy, liquidation or reorganization. Receivables are written-off against the allowances or reserves when they are determined to be uncollectible. Such determination includes analysis and consideration of the particular conditions of the account. Changes in the allowances were as follows: Year Ended December 31, 2021 2020 (1) 2019 Balance as of January 1, $ 247.6 $ 163.3 $ 282.4 Current year increases 130.9 105.6 104.3 Write-offs, recoveries and other (2) (22.6) (21.3) (223.4) Balance as of December 31, $ 355.9 $ 247.6 $ 163.3 _______________ (1) Year ended December 31, 2020 reflects the Company’s adoption of the current expected credit loss model for non-lease receivables. The adoption of this guidance did not have a material impact on the Company’s financial statements as the majority of the Company’s revenue is derived from its property operations and operating lease receivables are not within the scope of this guidance. (2) Amounts are primarily related to uncollectible amounts in India. Functional Currency —The functional currency of each of the Company’s foreign operating subsidiaries is normally the respective local currency, except for Costa Rica and Argentina, where the functional currency is the U.S. Dollar. All foreign currency assets and liabilities held by the subsidiaries are translated into U.S. Dollars at the exchange rate in effect at the end of the applicable fiscal reporting period and all foreign currency revenues and expenses are translated at the average monthly exchange rates. Translation adjustments are reflected in equity as a component of Accumulated other comprehensive loss (“AOCL”) in the consolidated balance sheets and included as a component of Comprehensive income in the consolidated statements of comprehensive income. Gains and losses on foreign currency transactions are reflected in Other expense in the consolidated statements of operations. However, the effect from fluctuations in foreign currency exchange rates on intercompany debt for which repayment is not anticipated in the foreseeable future is reflected in AOCL in the consolidated balance sheets and included as a component of Comprehensive income. The Company recorded the following net foreign currency (gains) losses: Year Ended December 31, 2021 2020 2019 Foreign currency losses recorded in AOCL $ 466.5 $ 391.0 $ 45.8 Foreign currency (gains) losses recorded in Other expense (557.9) 216.4 (6.1) Total foreign currency (gains) losses $ (91.4) $ 607.4 $ 39.7 Cash and Cash Equivalents —Cash and cash equivalents include cash on hand, demand deposits and short-term investments with original maturities of three months or less. The Company maintains its deposits at high-quality financial institutions and monitors the credit ratings of those institutions. Restricted Cash— Restricted cash includes cash pledged as collateral to secure obligations and all cash whose use is otherwise limited by contractual provisions. The reconciliation of cash and cash equivalents and restricted cash reported within the applicable balance sheet that sum to the total of the same such amounts shown in the statements of cash flows is as follows: Year Ended December 31, 2021 2020 2019 Cash and cash equivalents $ 1,949.9 $ 1,746.3 $ 1,501.2 Restricted cash 393.4 115.1 76.8 Total cash, cash equivalents and restricted cash $ 2,343.3 $ 1,861.4 $ 1,578.0 The increase in restricted cash during the year ended December 31, 2021 is due to advance payments from a customer. Property and Equipment —Property and equipment is recorded at cost or, in the case of acquired properties, at estimated fair value on the date acquired. Cost for self-constructed sites includes direct materials and labor and certain indirect costs associated with construction of the site, such as transportation costs, employee benefits and payroll taxes. The Company begins the capitalization of costs during the pre-construction period, which is the period during which costs are incurred to evaluate the site, and continues to capitalize costs until the site is substantially completed and ready for occupancy by a customer. Labor and related costs capitalized for the years ended December 31, 2021, 2020 and 2019 were $59.4 million, $51.1 million and $48.3 million, respectively. Expenditures for repairs and maintenance are expensed as incurred. Augmentation and improvements that extend an asset’s useful life or enhance capacity are capitalized. Depreciation expense is recorded using the straight-line method over the assets’ estimated useful lives. Towers and assets on leased land are depreciated over the shorter of the estimated useful life of the asset or the term of the corresponding ground lease, taking into consideration lease renewal options and residual value. Towers or assets acquired through finance leases are recorded net at the present value of future minimum lease payments or the fair value of the leased asset at the inception of the lease. Property and equipment and assets held under finance leases are amortized over the shorter of the applicable lease term or the estimated useful life of the respective assets for periods generally not exceeding twenty years. The Company reviews its asset portfolio for indicators of impairment on an individual site basis. Impairments primarily result from a site not having current tenant leases or from having expenses in excess of revenues. The Company reviews other long-lived assets for impairment whenever events, changes in circumstances or other evidence indicate that the carrying amount of the Company’s assets may not be recoverable. The Company records impairment charges, which are discussed in note 17, in Other operating expenses in the consolidated statements of operations in the period in which the Company identifies such impairment. Goodwill and Other Intangible Assets —The Company reviews goodwill for impairment at least annually (as of December 31) or whenever events or circumstances indicate the carrying value of an asset may not be recoverable. Goodwill is recorded in the applicable segment and assessed for impairment at the reporting unit level. The Company employs a discounted cash flow analysis when testing goodwill for impairment. The key assumptions utilized in the discounted cash flow analysis include current operating performance, terminal sales growth rate, management’s expectations of future operating results and cash requirements, the current weighted average cost of capital and an expected tax rate. The Company compares the fair value of the reporting unit, as calculated under an income approach using future discounted cash flows, to the carrying amount of the applicable reporting unit. If the carrying amount exceeds the fair value, an impairment loss would be recognized for the amount of the excess. The loss recognized is limited to the total amount of goodwill allocated to that reporting unit. During the years ended December 31, 2021, 2020 and 2019, no potential impairment was identified, as the fair value of each of the reporting units was in excess of its carrying amount. Intangible assets that are separable from goodwill and are deemed to have a definite life are amortized over their useful lives, generally ranging from three The Company reviews its network location intangible assets for indicators of impairment on an individual tower basis. Impairments primarily result from a site not having current tenant leases or from having expenses in excess of revenues. The Company monitors its tenant-related intangible assets on a tenant by tenant basis for indicators of impairment, such as high levels of turnover or attrition, non-renewal of a significant number of contracts or the cancellation or termination of a relationship. The Company assesses recoverability by determining whether the carrying amount of the related assets will be recovered primarily through projected undiscounted future cash flows. If the Company determines that the carrying amount of an asset may not be recoverable, the Company measures any impairment loss based on the projected future discounted cash flows to be provided from the asset or available market information relative to the asset’s fair value, as compared to the asset’s carrying amount. The Company records impairment charges, which are discussed in note 17, in Other operating expenses in the consolidated statements of operations in the period in which the Company identifies such impairment. Derivative Financial Instruments —Derivatives are recorded on the consolidated balance sheet at fair value. If a derivative is designated as a cash flow hedge, the effective portions of changes in the fair value of the derivative are recorded in AOCL, as well as a component of comprehensive income, and are recognized in the results of operations when the hedged item affects earnings. Changes in fair value of the ineffective portions of cash flow hedges are recognized in the results of operations. For derivative instruments that are designated and qualify as fair value hedges, changes in value of the derivatives are recorded in Other expense in the consolidated statements of operations in the current period, along with the offsetting gain or loss on the hedged item attributable to the hedged risk. For derivative instruments not designated as hedging instruments, changes in fair value are recognized in the results of operations in the period that the change occurs. The primary risks managed through the use of derivative instruments is interest rate risk, exposure to changes in the fair value of debt attributable to interest rate risk and currency risk. From time to time, the Company enters into interest rate swap agreements or foreign currency contracts to manage exposure to these risks. Under these agreements, the Company is exposed to counterparty credit risk to the extent that a counterparty fails to meet the terms of a contract. The Company’s exposure is limited to the current value of the contract at the time the counterparty fails to perform. The Company assesses, both at the inception of the hedge and on an ongoing basis, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in cash flows or fair values of hedged items. The Company does not hold derivatives for trading purposes. 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. Asset Retirement Obligations —When required, the Company recognizes the fair value of obligations to remove its assets and remediate the leased space upon which certain of its assets are located. Generally, the associated retirement costs are capitalized as part of the carrying amount of the related assets and depreciated over their estimated useful lives and the liability is accreted through the obligation’s estimated settlement date. Fair value estimates of asset retirement obligations generally involve discounting of estimated future cash flows associated with remediation costs. Periodic accretion of such liabilities due to the passage of time is included in Depreciation, amortization and accretion expense in the consolidated statements of operations. Adjustments are also made to the asset retirement obligation liability to reflect changes in the estimates of timing and amount of expected cash flows, with an offsetting adjustment made to the related long-lived tangible asset. The significant assumptions used in estimating the Company’s aggregate asset retirement obligation are: timing of asset removals; cost of asset removals; timing and number of site lease renewals; expected inflation rates; and credit-adjusted, risk-free interest rates that approximate the Company’s incremental borrowing rate. Income Taxes —As a REIT, the Company generally is not subject to U.S. federal income taxes on income generated by its REIT operations as it receives a dividends paid deduction for distributions to stockholders that generally offsets its REIT income and gains. However, the Company remains obligated to pay U.S. federal income taxes on certain earnings and continues to be subject to taxation in its foreign jurisdictions. Accordingly, the consolidated financial statements reflect provisions for federal, state, local and foreign income taxes. The Company recognizes deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis, as well as operating loss and tax credit carryforwards. The Company measures deferred tax assets and liabilities using enacted tax rates expected to apply to taxable income in the years in which those temporary differences and carryforwards are expected to be recovered or settled. The effect on deferred tax assets and liabilities as a result of a change in tax rates is recognized in income in the period that includes the enactment date. The Company periodically reviews its deferred tax assets, and 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. Valuation allowances would be reversed as a reduction to the provision for income taxes if related deferred tax assets are deemed realizable based on changes in facts and circumstances relevant to the assets’ recoverability. The Company estimates the liabilities from uncertain tax positions, which are recorded in Other non-current liabilities in the consolidated balance sheet, unless expected to be paid within one year. The Company reports penalties and tax-related interest expense as a component of the income tax provision and interest income from tax refunds as a component of Interest income in the consolidated statements of operations. Other Comprehensive Income (Loss) —Other comprehensive income (loss) refers to items excluded from net income that are recorded as an adjustment to equity, net of tax. The Company’s other comprehensive income (loss) primarily consisted of changes in fair value of effective derivative cash flow hedges, foreign currency translation adjustments and reclassification of unrealized losses on effective derivative cash flow hedges. The AOCL balance included accumulated foreign currency translation losses of $4.7 billion, $3.8 billion and $2.8 billion as of December 31, 2021, 2020 and 2019, respectively. Distributions —As a REIT, the Company must annually distribute to its stockholders an amount equal to at least 90% of its REIT taxable income (determined before the deduction for distributed earnings and excluding any net capital gain). Generally, the Company has distributed, and expects to continue to distribute, all or substantially all of its REIT taxable income after taking into consideration its utilization of net operating losses (“NOLs”). The amount, timing and frequency of future distributions will be at the sole discretion of the Board of Directors and will depend upon various factors, a number of which may be beyond the Company’s control, including the Company’s financial condition and operating cash flows, the amount required to maintain its qualification for taxation as a REIT and reduce any income and excise taxes that the Company otherwise would be required to pay, limitations on distributions in the Company’s existing and future debt and preferred equity instruments, the Company’s ability to utilize NOLs to offset the Company’s distribution requirements, limitations on its ability to fund distributions using cash generated through its TRSs and other factors that the Board of Directors may deem relevant. Acquisitions —For acquisitions that meet the definition of a business combination, the Company applies the acquisition method of accounting where assets acquired and liabilities assumed are recorded at fair value at the date of each acquisition, and the results of operations are included with those of the Company from the dates of the respective acquisitions. Any excess of the purchase price paid by the Company over the amounts recognized for assets acquired and liabilities assumed is recorded as goodwill. The Company continues to evaluate acquisitions for a period not to exceed one year after the applicable acquisition date of each transaction to determine whether any additional adjustments are needed to the allocation of the purchase price paid for the assets acquired and liabilities assumed. All other acquisitions are accounted for as asset acquisitions and the purchase price is allocated to the net assets acquired with no recognition of goodwill. The purchase price is not subsequently adjusted. The fair value of the assets acquired and liabilities assumed is typically determined by using either estimates of replacement costs or discounted cash flow valuation methods. When determining the fair value of tangible assets acquired, the Company must estimate the cost to replace the asset with a new asset taking into consideration such factors as age, condition and the economic useful life and productive capacity of the asset. When determining the fair value of intangible assets acquired and liabilities assumed, the Company must estimate the applicable discount rate and the timing and amount of future cash flows, including rate and terms of renewal and attrition. Revenue —The Company’s revenue is derived from leasing the right to use its communications sites, the land on which the sites are located and its data center facilities (the “lease component”) and from the reimbursement of costs incurred by the Company in operating the communications sites and data center facilities and supporting its customers’ equipment as well as other services and contractual rights (the “non-lease component”). Most of the Company’s revenue is derived from leasing arrangements and is accounted for as lease revenue unless the timing and pattern of revenue recognition of the non-lease component differs from the lease component. If the timing and pattern of the non-lease component revenue recognition differs from that of the lease component, the Company separately determines the stand-alone selling prices and pattern of revenue recognition for each performance obligation. Revenue related to DAS networks and fiber and other related assets results from agreements with tenants are generally not accounted for as leases. The Company’s revenue from leasing arrangements, including fixed escalation clauses present in non-cancellable lease arrangements, is reported on a straight-line basis over the term of the respective leases when collectibility is probable. Escalation clauses tied to a consumer price index (“CPI”), or other inflation-based indices, and other incentives present in lease agreements with the Company’s tenants are excluded from the straight-line calculation. Total property straight-line revenues for the years ended December 31, 2021, 2020 and 2019 were $465.6 million, $322.0 million and $183.5 million, respectively. Non-lease property revenue— Non-lease property revenue consists primarily of revenue generated from DAS networks, fiber and other property related revenue. DAS networks and fiber arrangements generally require that the Company provide the tenant the right to use available capacity on the applicable communications infrastructure. Performance obligations are satisfied over time for the duration of the arrangements. Non-lease property revenue also includes revenue generated from interconnection services in the Company’s data center facilities. Interconnection services are generally contracted on a month-to-month basis and are cancellable by the Company or the data center customer at any time. Performance obligations are satisfied over time for the duration of the arrangements. Other property related revenue streams, which include site inspections, are not material on either an individual or consolidated basis. Services revenue— The Company offers tower-related services in the United States. These services include AZP and structural analysis. There is a single performance obligation related to AZP and revenue is recognized over time based on milestones achieved, which are determined based on costs expected to be incurred. Structural analysis services may have more than one performance obligation, contingent upon the number of contracted services. Revenue is recognized at the point in time the services are completed. Some of the Company’s contracts with customers contain multiple performance obligations. For these arrangements, the Company allocates revenue to each performance obligation based on its relative standalone selling price, which is typically based on the price charged to customers. Since most of the Company’s contracts are leases, costs to enter into lease arrangements are capitalized under the applicable lease accounting guidance. Costs incurred to obtain non-lease contracts that are capitalized primarily relate to DAS networks and are not material to the consolidated financial statements. The Company has excluded sales tax, value added tax and similar taxes from non-lease revenue. Revenue is disaggregated by geography in a manner consistent with the Company’s business segments, which are discussed further in note 21. A summary of revenue disaggregated by source and geography is as follows: Year Ended December 31, 2021 U.S. & Canada Asia-Pacific Africa Europe Latin Data Centers (1) Total Non-lease property revenue $ 291.9 $ 8.8 $ 24.4 $ 7.6 $ 135.9 $ 1.3 $ 469.9 Services revenue 247.3 — — — — — 247.3 Total non-lease revenue $ 539.2 $ 8.8 $ 24.4 $ 7.6 $ 135.9 $ 1.3 $ 717.2 Property lease revenue 4,628.3 1,190.3 981.1 488.6 1,329.5 21.9 8,639.7 Total revenue $ 5,167.5 $ 1,199.1 $ 1,005.5 $ 496.2 $ 1,465.4 $ 23.2 $ 9,356.9 _______________ (1) Data Centers consists of the Company’s data center facilities located in the United States.

Leases [Abstract] | |
LEASES | LEASES The Company determines if an arrangement is a lease at the inception of the agreement. The Company considers an arrangement to be a lease if it conveys the right to control the use of the communications infrastructure or ground space underneath a communications infrastructure for a period of time in exchange for consideration. The Company is both a lessor and a lessee. Lessor —The Company is a lessor in most of its revenue arrangements, as property revenue is derived from tenant leases of specifically-identified, physically distinct space on or in the Company’s communications real estate assets. The Company’s lease arrangements with its tenants for its communications sites vary depending upon the region and the industry of the tenant and generally have initial non-cancellable terms of five The Company’s leasing arrangements outside of the United States may require that the Company provide power to the communications site through an electrical grid connection, diesel fuel generators or other sources and permit the Company to pass through the costs of, or otherwise charge for, these services. Many arrangements require that the communications site has power for a specified percentage of time. In most cases, if delivery of power falls below the specified service level, a corresponding reduction in revenue is recorded. The Company has determined that this performance obligation is satisfied over time for the duration of the lease. In addition, the Company provides power to its data center customers, which is passed through, or otherwise charged, to customers pursuant to the terms of the customer power arrangement. Customer power arrangements are coterminous with such customer’s underlying lease and have the same pattern of transfer over the lease term. This performance obligation is generally satisfied over time for the duration of the lease. Fixed power revenue is recognized each month over the term of the lease. For variable power arrangements, the Company recognizes revenue each month as the uncertainty related to the consideration is resolved. The Company typically has more than one tenant on a site and, by performing ordinary course repair and maintenance work, can often lease a site, either through renewing existing agreements or leasing to new tenants, for periods beyond the existing tenant lease term. Accordingly, the Company has minimal risk with respect to the residual value of its leased assets. Communications infrastructure assets are depreciated over their estimated useful lives, which generally do not exceed twenty years. As of December 31, 2021, the Company does not have any material related party leases as a lessor. To the extent there are any intercompany leases, these are eliminated in consolidation. The Company generally does not enter into sales-type leases or direct financing leases. The Company’s leases generally do not include any incentives for the lessee, however, if incentives are present, they are evaluated to determine proper treatment and, to the extent present, are recorded in Other current assets and Other non-current assets in the consolidated balance sheets. In addition, the Company’s leases do not include any lessee purchase options. Historically, the Company has been able to successfully renew its ground leases as needed to ensure continuation of its revenue. Accordingly, the Company assumes that it will have access to the land underneath its sites when calculating future minimum rental receipts. Future minimum rental receipts expected under non-cancellable operating lease agreements as of December 31, 2021, were as follows: Fiscal Year Amount (1) 2022 $ 6,477.8 2023 6,958.9 2024 6,746.9 2025 6,247.6 2026 5,664.8 Thereafter 29,330.2 Total $ 61,426.2 _______________ (1) Balances are translated at the applicable period-end exchange rate, which may impact comparability between periods. Lessee —The Company enters into arrangements as a lessee primarily for ground space underneath its communications sites. These arrangements are typically long-term lease agreements with initial non-cancellable terms of approximately five The Company’s lease liability is the present value of the remaining minimum rental payments to be made over the remaining lease term, including renewal options reasonably certain to be exercised. The Company also considers termination options and factors those into the determination of lease payments when appropriate. To determine the lease term, the Company considers all renewal periods that are reasonably certain to be exercised, taking into consideration all economic factors, including the communications site’s estimated economic life (generally twenty years) and the respective lease terms of the Company’s tenants under the existing lease arrangements on such site. The Company assesses its right-of-use asset and other lease-related assets for impairment, as described in note 1. During the years ended December 31, 2021, 2020 and 2019, the Company recorded $3.3 million, $76.1 million and $9.9 million, respectively, of impairment expense related to these assets. As of December 31, 2021, the Company does not have any material related party leases as a lessee. The Company does not have any sale-leaseback arrangements as lessee and typically does not enter into leveraged leases. The Company leases certain land, buildings, equipment and office space under operating leases and land and improvements, towers, equipment and vehicles under finance leases. As of December 31, 2021, operating lease assets were included in Right-of-use asset and finance lease assets Information about other lease-related balances is as follows: As of December 31, 2021 December 31, 2020 Operating leases: Right-of-use asset $ 9,225.1 $ 7,789.2 Current portion of lease liability $ 712.6 $ 539.9 Lease liability 8,041.8 6,884.4 Total operating lease liability $ 8,754.4 $ 7,424.3 Finance leases: Current portion of lease liability $ 6.7 $ 4.9 Lease liability 24.9 23.0 Total finance lease liability $ 31.6 $ 27.9 As most of the Company’s leases do not specifically state an implicit rate, the Company uses a market-specific incremental borrowing rate consistent with the lease term as of the lease commencement date or upon a remeasurement event when calculating the present value of the remaining lease payments. The incremental borrowing rate reflects the cost to borrow on a securitized basis in each market. The remaining lease term does not reflect all renewal options available to the Company, only those renewal options that the Company has assessed as reasonably certain of being exercised taking into consideration the economic and other factors noted above. The weighted-average remaining lease terms and incremental borrowing rates are as follows: As of December 31, 2021 December 31, 2020 Operating leases: Weighted-average remaining lease term (years) 13.0 13.7 Weighted-average incremental borrowing rate 5.1 % 5.6 % Finance leases: Weighted-average remaining lease term (years) 13.4 12.1 Weighted-average incremental borrowing rate 6.3 % 6.8 % The following table sets forth the components of lease cost for the years ended December 31,: 2021 2020 2019 Operating lease cost $ 1,115.1 $ 977.2 $ 1,013.1 Variable lease costs not included in lease liability (1) 339.6 280.0 261.7 _______________ (1) Includes property tax paid on behalf of the landlord.

LEASES | LEASES The Company determines if an arrangement is a lease at the inception of the agreement. The Company considers an arrangement to be a lease if it conveys the right to control the use of the communications infrastructure or ground space underneath a communications infrastructure for a period of time in exchange for consideration. The Company is both a lessor and a lessee. Lessor —The Company is a lessor in most of its revenue arrangements, as property revenue is derived from tenant leases of specifically-identified, physically distinct space on or in the Company’s communications real estate assets. The Company’s lease arrangements with its tenants for its communications sites vary depending upon the region and the industry of the tenant and generally have initial non-cancellable terms of five The Company’s leasing arrangements outside of the United States may require that the Company provide power to the communications site through an electrical grid connection, diesel fuel generators or other sources and permit the Company to pass through the costs of, or otherwise charge for, these services.

Africa consists of measurement period adjustments related to the acquisition of Eaton Towers Holdings Limited (the “Eaton Towers Acquisition”). (2) U.S. & Canada consists of measurement period adjustments related to the InSite Acquisition. Asia-Pacific consists of $9.2 million of additions related to the Bangladesh Acquisition (as discussed in note 6) and measurement period adjustments related to the InSite Acquisition. Europe and Latin America consist of additions and measurement period adjustments related to the Telxius Acquisition (as defined in note 6). Data Centers consists of $3.0 billion of additions related to data center acquisitions, primarily from the CoreSite Acquisition. The Company’s other intangible assets subject to amortization consisted of the following: As of December 31, 2021 As of December 31, 2020 Estimated Useful Gross Accumulated Net Book Gross Accumulated Net Book Acquired network location intangibles (1) Up to 20 $ 6,294.6 $ (2,305.1) $ 3,989.5 $ 5,784.0 $ (2,117.6) $ 3,666.4 Acquired tenant-related intangibles Up to 20 20,030.5 (5,051.5) 14,979.0 14,322.5 (4,237.5) 10,085.0 Acquired licenses and other intangibles (2) 2-20 1,807.9 (49.2) 1,758.7 97.8 (9.4) 88.4 Total other intangible assets $ 28,133.0 $ (7,405.8) $ 20,727.2 $ 20,204.3 $ (6,364.5) $ 13,839.8 _______________ (1) Acquired network location intangibles are amortized over the shorter of the term of the corresponding ground lease, taking into consideration lease renewal options and residual value, generally up to 20 years, as the Company considers these intangibles to be directly related to the tower assets. (2) In connection with the CoreSite Acquisition, the Company acquired $1.7 billion of other intangible assets. The acquired other intangible assets will amortize over periods ranging from approximately two years to 10 years. 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 tower communications infrastructure. The acquired tenant-related intangibles typically represent the value to the Company of tenant contracts and relationships in place at the time of an acquisition or similar transaction, including assumptions regarding estimated renewals. Other intangibles represent the value of acquired licenses, trade name and in place leases. In place lease value represents the fair value of costs avoided in securing data center customers, including vacancy periods, legal costs and commissions. In addition, this value also includes assumptions on similar costs avoided upon the renewal or extension of existing leases on a basis consistent with occupancy assumptions used in the fair value of other assets. The Company amortizes its acquired network location intangibles and tenant-related intangibles on a straight-line basis over their estimated useful lives. As of December 31, 2021, the remaining weighted average amortization period of the Company’s intangible assets wa s 15 years . Amortization of intangible assets for the years ended December 31, 2021, 2020 and 2019 was $1.2 billion, $867.2 million and $791.3 million, respectively. Based on current exchange rates, the Company expects to record amortization expense as follows over the next five years: Fiscal Year Amount 2022 $ 1,802.4 2023 1,366.9 2024 1,352.8 2025 1,271.8 2026 1,237.5 |

For those transactions treated as asset acquisitions, the purchase price is allocated to the assets or rights acquired and liabilities assumed, with no recognition of goodwill. For those transactions treated as business combinations, 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 tax positions, which may include 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 for those acquisitions accounted for as business combinations, the Company will adjust assets or liabilities if new information is obtained about facts and 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. Impact of current year acquisitions —The Company typically acquires communications sites and other communications infrastructure assets from wireless carriers or other tower operators and subsequently integrates those sites and related assets into its existing portfolio of communications sites and related assets. In the United States, the Company has also acquired data center facilities and related assets, including the CoreSite Acquisition, as discussed below. The financial results of the Company’s acquisitions have been included in the Company’s consolidated statements of operations for the year ended December 31, 2021 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 depend on, 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 instead have been utilized solely by the seller as a component of its network infrastructure. An acquisition may or may not involve the transfer of business operations or employees. 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; for transactions accounted for as asset acquisitions, these costs are capitalized as part of the purchase price. Acquisition and merger related costs may include finder’s fees, advisory, legal, accounting, valuation and other professional or consulting fees and general administrative costs directly related to completing the transaction. Integration costs include incremental and non-recurring costs necessary to convert data and systems, retain employees and otherwise enable the Company to operate acquired businesses or assets efficiently. The Company records acquisition and merger related expenses for business combinations, as well as integration costs for all acquisitions, in Other operating expenses in the consolidated statements of operations. During the years ended December 31, 2021, 2020 and 2019, the Company recorded acquisition and merger related expenses for business combinations and non-capitalized asset acquisition costs and integration costs as follows: Year Ended December 31, 2021 2020 2019 Acquisition and merger related expenses $ 177.0 $ 15.5 $ 26.9 Integration costs $ 50.4 $ 23.1 $ 9.8 During the years ended December 31, 2021, 2020 and 2019, the Company recorded net benefits of $17.6 million, $4.4 million and $13.1 million related to pre-acquisition contingencies and settlements, respectively. The increase in acquisition and merger related costs during the year ended December 31, 2021 was primarily associated with the Telxius Acquisition and the CoreSite Acquisition. 2021 Transactions The estimated aggregate impact of the acquisitions completed in 2021 on the Company’s revenues and gross margin for the year ended December 31, 2021 was approximately $424.3 million and $214.8 million, respectively. The revenues and gross margin amounts also reflect incremental revenues from the addition of new customers to such communications infrastructure assets subsequent to the transaction date. Acquisitions completed in 2021 were included in all of the Company’s property segments. Data Centers U.S. Data Centers Acquisition— On October 5, 2021, the Company completed the acquisition of two multi-customer data center facilities in the United States markets for total consideration of approximately $200.6 million. The acquired assets and operations are included in the Data Centers segment. This acquisition is being accounted for as a business combination and is subject to post-closing adjustments. This acquisition is included in the table below in “Other.” CoreSite Acquisition —On November 14, 2021, the Company entered into an agreement with CoreSite to acquire all issued and outstanding shares of CoreSite common stock at $170.00 per share. CoreSite’s portfolio consisted of 24 data center facilities and related assets in eight United States markets. On December 28, 2021, the Company completed the CoreSite Acquisition for total consideration of approximately $10.4 billion, including the assumption and repayment of CoreSite’s existing debt. The acquired assets and operations are included in the Data Centers segment. The CoreSite Acquisition was accounted for as a business combination and is subject to post-closing adjustments. Communications Sites Telxius Acquisition —On January 13, 2021, the Company entered into two agreements with Telxius Telecom, S.A. (“Telxius”), a subsidiary of Telefónica, S.A., pursuant to which the Company agreed to acquire Telxius’ European and Latin American tower divisions, comprising approximately 31,000 communications sites in Argentina, Brazil, Chile, Germany, Peru and Spain, for approximately 7.7 billion Euros (“EUR”) (approximately $9.4 billion at the date of signing) (the “Telxius Acquisition”), subject to certain adjustments. In June 2021, the Company completed the acquisition of nearly 20,000 communications sites in Germany and Spain, for total consideration of approximately 6.3 billion EUR (approximately $7.7 billion at the date of closing), subject to certain post-closing adjustments and over 7,000 communications sites in Brazil, Peru, Chile and Argentina, for total consideration of approximately 0.9 billion EUR (approximately $1.1 billion at the date of closing), subject to certain post-closing adjustments. On August 2, 2021, the Company completed the acquisition of the approximately 4,000 remaining communications sites in Germany pursuant to the Telxius Acquisition for 0.6 billion EUR (approximately $0.7 billion at the date of closing), subject to certain post-closing adjustments. Of the aggregate purchase price, 233.2 million EUR (approximately $265.2 million), including post-closing adjustments, of deferred payments are due in September 2025 and are reflected in Other non-current liabilities in the consolidated balance sheet as of December 31, 2021. The acquired operations in Germany and Spain are included in the Europe property segment and the acquired operations in Brazil, Peru, Chile and Argentina are included in the Latin America property segment. The Telxius Acquisition was accounted for as a business combination and is subject to post-closing adjustments. Subsequent to the acquisition dates, certain adjustments were made to increase assets by $6.0 million and reduce liabilities by $58.7 million, with a corresponding decrease in goodwill of $64.7 million. There were no other material post-closing adjustments. The full reconciliation and finalization of the assets acquired and liabilities assumed, including those subject to valuation, have not been completed and, as a result, there may be additional post-closing adjustments. Entel Acquisition —On December 19, 2019, the Company entered into a definitive agreement to acquire approximately 3,200 communications sites in Chile and Peru from Entel PCS Telecomunicaciones S.A. and Entel Peru S.A. (“Entel”) for total consideration of approximately $0.8 billion (as of the date of signing). The Company completed the acquisition of approximately 2,400 communications sites in December 2019 and an additional 530 communications sites pursuant to this agreement during the year ended December 31, 2020. During the year ended December 31, 2021, the Company completed the acquisition of the remaining 156 communications sites pursuant to this agreement for an aggregate total purchase price of $44.5 million (as of the dates of acquisition), including value added tax, which have been accounted for as an acquisition of assets and are included in the table below in “Other.” Bangladesh Acquisition —During the year ended December 31, 2021, the Company acquired a 51% controlling interest in Kirtonkhola Tower Bangladesh Limited (“KTBL”) for 900 million Bangladeshi Taka (“BDT”) (approximately $10.6 million at the date of closing). Confidence Group holds a 49% noncontrolling interest in KTBL. This acquisition is being accounted for as a business combination and is subject to post-closing adjustments. This acquisition is included in the table below in “Other.” Other Acquisitions— During the year ended December 31, 2021, the Company acquired a total of 1,309 communications sites as well as other communications infrastructure assets, in the United States, France, Mexico, Nigeria, Peru and Poland, including 633 communications sites in connection with the Company’s agreements with Orange S.A. (“Orange”) as further described below, for an aggregate purchase price of $565.6 million. Of the aggregate purchase price, $89.8 million is reflected as a payable in the consolidated balance sheet as of December 31, 2021. These acquisitions were primarily accounted for as asset acquisitions and are included in the table below in “Other.” The following table summarizes the allocations of the purchase prices for the fiscal year 2021 acquisitions based upon their estimated fair value at the date of acquisition: CoreSite Acquisition Telxius Acquisition Other (1) Current assets $ 99.8 $ 284.9 $ 56.4 Property and equipment 5,129.0 1,414.6 391.3 Intangible assets (2): Tenant-related intangible assets 665.0 5,371.3 308.3 Network location intangible assets — 672.0 88.0 Other intangible assets 1,709.0 — 1.7 Other non-current assets 332.9 1,398.4 52.5 Current liabilities (156.6) (338.9) (15.7) Deferred tax liability — (1,195.4) — Other non-current liabilities (323.1) (1,534.2) (61.0) Net assets acquired 7,456.0 6,072.7 821.5 Goodwill (3) 2,943.3 3,517.0 10.0 Fair value of net assets acquired 10,399.3 9,589.7 831.5 Debt assumed (4) (955.1) — — Noncontrolling interest — — (10.2) Purchase price (5) $ 9,444.2 $ 9,589.7 $ 821.3 ______________ (1) Includes 21 sites in Peru held pursuant to long-term finance leases.

The CoreSite Replacement Awards will continue to vest in accordance with the terms of CoreSite’s equity plan. The fair value of the CoreSite Replacement Awards for services rendered through December 28, 2021, the CoreSite Acquisition date, was recognized as a component of the purchase price, with the remaining fair value of the CoreSite Replacement Awards related to the post-combination services recorded as stock-based compensation over the remaining vesting period. Other Signed Acquisitions Orange Acquisition— On November 28, 2019, the Company entered into definitive agreements with Orange for the acquisition of up to approximately 2,000 communications sites in France over a period of up to five years for total consideration in the range of approximately 500.0 million EUR to 600.0 million EUR (approximately $550.5 million to $660.5 million at the date of signing) to be paid over the five-year term. During the year ended December 31, 2020, the Company completed the acquisition of 564 of these communications sites. During the year ended December 31, 2021, the Company completed the acquisition of an additional 633 of these communications sites.

Fair Value Disclosures [Abstract] | |
FAIR VALUE MEASUREMENTS | 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. Items Measured at Fair Value on a Recurring Basis —The fair values of the Company’s financial assets and liabilities that are required to be measured on a recurring basis at fair value were as follows: December 31, 2021 December 31, 2020 Fair Value Measurements Using Fair Value Measurements Using Level 1 Level 2 Level 3 Level 1 Level 2 Level 3 Assets: Interest rate swap agreements — $ 11.0 — — $ 29.2 — Investments in equity securities (1) $ 37.1 — — — $ 6.0 — Liabilities: Interest rate swap agreements — — — — $ 0.1 — Fair value of debt related to interest rate swap agreements (2) $ 12.2 — — $ 31.4 — — _______________ (1) Investments in equity securities are recorded in Notes receivable and other non-current assets in the consolidated balance sheet at fair value. Unrealized holding gains and losses for equity securities are recorded in Other income (expense) in the consolidated statements of operations in the current period. During the year ended December 31, 2021 , the Company recognized unrealized gains of $6.1 million for equity securities held as of December 31, 2021. (2) Included in the carrying values of the corresponding debt obligations. 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. For derivative instruments that are designated and qualify as fair value hedges, changes in the value of the derivatives are recognized in the consolidated statements of operations in the current period, along with the offsetting gain or loss on the hedged item attributable to the hedged risk. For derivative instruments that are designated and qualify as cash flow hedges, the Company records the change in fair value for the effective portion of the cash flow hedges in AOCL in the consolidated balance sheets and reclassifies a portion of the value from AOCL into Interest expense on a quarterly basis as the cash flows from the hedged item affects earnings. The Company records the settlement of interest rate swap agreements in (Loss) gain on retirement of long-term obligations in the consolidated statements of operations in the period in which the settlement occurs. The Company entered into three interest rate swap agreements with an aggregate notional value of $500.0 million related to the 3.000% senior unsecured notes due 2023 (the “3.000% Notes”). These interest rate swaps, which were designated as fair value hedges at inception, were entered into to hedge against changes in fair value of the 3.000% Notes resulting from changes in interest rates. The interest rate swap agreements require the Company to pay interest at a variable interest rate of one-month LIBOR plus applicable spreads and to receive fixed interest at a rate of 3.000% through June 15, 2023. The Company entered into three interest rate swap agreements with an aggregate notional value of $600.0 million related to the 2.250% Notes. These interest rate swaps, which were designated as fair value hedges at inception, were entered into to hedge against changes in fair value of the 2.250% Notes resulting from changes in interest rates. The interest rate swap agreements required the Company to pay interest at a variable interest rate of one-month LIBOR plus applicable spreads and to receive fixed interest at a rate of 2.250% through January 15, 2022. The interest rate swap agreements expired upon repayment of the 2.250% Notes in full on January 14, 2022 upon maturity. The fair value of the interest rate swap agreements in the United States at December 31, 2021 and 2020 was $11.0 million and $29.2 million, respectively, and was included in Other non-current assets on the consolidated balance sheets. During the year ended December 31, 2021, the Company recorded net fair value adjustments of $0.9 million related to interest rate swaps and the change in fair value of debt due to interest rate swaps in Other expense in the consolidated statements of operations. One of the Company’s Colombian subsidiaries was party to an interest rate swap agreement with certain lenders under the Colombian Credit Facility (the “Colombia Interest Rate Swap”). The Colombia Interest Rate Swap, which was designated as a cash flow hedge at inception, was entered into to manage exposure to variability in interest rates on debt. The Colombia Interest Rate Swap required the payment of a fixed interest rate of 5.37% and paid variable interest at the three-month Inter-bank Rate through the earlier of termination of the underlying debt or April 24, 2021. On April 24, 2021, the interest rate swap agreement with certain lenders under the Colombian Credit Facility expired upon maturity of the underlying debt. As of December 31, 2021, there were no amounts outstanding under the Colombia Interest Rate Swap. The fair value of the Colombia Interest Rate Swap as of December 31, 2020 was less than $0.1 million and was included in Other non-current liabilities on the consolidated balance sheets. Items Measured at Fair Value on a Nonrecurring Basis Assets Held and Used —The Company’s long-lived assets are recorded at amortized cost and, if impaired, are adjusted to fair value using Level 3 inputs. During the year ended December 31, 2021, certain long-lived assets held and used with a carrying value of $49.0 billion were written down to their net realizable value as a result of an asset impairment charge of $173.7 million. During the year ended December 31, 2020, certain long-lived assets held and used with a carrying value of $24.1 billion were written down to their net realizable value as a result of an asset impairment charge of $222.8 million. The asset impairment charges are recorded in Other operating expenses in the accompanying consolidated statements of operations. These adjustments were determined by comparing the estimated fair value utilizing projected future discounted cash flows to be provided from the long-lived assets to the asset’s carrying value. There were no other items measured at fair value on a nonrecurring basis during the year ended December 31, 2021. Fair Value of Financial Instruments —The Company’s financial instruments for which the carrying value reasonably approximates fair value at December 31, 2021 and 2020 include 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 December 31, 2021, the carrying value and fair value of long-term obligations, including the current portion, were $43.3 billion and $44.1 billion, respectively, of which $28.5 billion was measured using Level 1 inputs and $15.6 billion was measured using Level 2 inputs. As of December 31, 2020, the carrying value and fair value of long-term obligations, including the current portion, were $29.3 billion and $31.4 billion, respectively, of which $24.0 billion was measured using Level 1 inputs and $7.4 billion was measured using Level 2 inputs. |

Income Tax Disclosure [Abstract] | |
INCOME TAXES | INCOME TAXES Beginning in the taxable year ended December 31, 2012, the Company has filed, and intends to continue to file, U.S. federal income tax returns as a REIT, and its domestic TRSs filed, and intend to continue to file, separate tax returns as required. The Company also files tax returns in various states and countries. The Company’s state tax returns reflect different combinations of the Company’s subsidiaries and are dependent on the connection each subsidiary has with a particular state and form of organization. The following information pertains to the Company’s income taxes on a consolidated basis. The income tax provision from continuing operations consisted of the following: Year Ended December 31, 2021 2020 2019 Current: Federal $ (26.0) $ 8.7 $ (1.7) State (9.3) (10.7) (5.0) Foreign (267.7) (150.1) (48.2) Deferred: Federal 0.0 (1.0) 1.4 State (2.5) (1.0) 0.5 Foreign 43.7 24.5 53.2 Income tax (provision) benefit $ (261.8) $ (129.6) $ 0.2 The effective tax rate (“ETR”) on income from continuing operations for the years ended December 31, 2021, 2020 and 2019 differs from the federal statutory rate primarily due to the Company’s qualification for taxation as a REIT, as well as adjustments for state and foreign items. As a REIT, the Company may deduct earnings distributed to stockholders against the income generated by its REIT operations. In addition, the Company is able to offset certain income by utilizing its remaining NOLs, subject to specified limitations. For the year ended December 31, 2021, the change in the income tax provision was primarily attributable to increases in reserves for uncertain tax positions and tax audit settlements, primarily in the United States and Mexico, in the current year. In 2019, there was an income tax law change in India that allows companies to elect into an optional concessional tax regime. The new regime allows for a lower effective tax rate from approximately 35% to approximately 25% and no minimum alternative tax, while disallowing the benefit of the minimum alternative tax credits. As a result, the Company recorded a $113.0 million one-time tax benefit during the year ended December 31, 2019 arising from revaluing its net deferred tax liability. Reconciliation between the U.S. statutory rate and the effective rate from continuing operations is as follows: Year Ended December 31, 2021 2020 2019 Statutory tax rate 21 % 21 % 21 % Adjustment to reflect REIT status (1) (21) (21) (21) Foreign taxes 3 4 3 Foreign withholding taxes 2 3 3 Uncertain tax positions 4 1 1 Changes in tax laws — — (6) Impact from restructuring — — (1) Changes in valuation allowance (0) (1) — Effective tax rate 9 % 7% (0)% _______________ (1) As a result of the ability to utilize the dividends paid deduction to offset the Company’s REIT income and gains. The domestic and foreign components of income from continuing operations before income taxes are as follows: Year Ended December 31, 2021 2020 2019 United States $ 2,517.4 $ 1,683.0 $ 1,527.0 Foreign 312.0 138.1 389.4 Total $ 2,829.4 $ 1,821.1 $ 1,916.4 The components of the net deferred tax asset and liability and related valuation allowance were as follows: December 31, 2021 December 31, 2020 Assets: Operating lease liability $ 1,171.8 $ 837.1 Net operating loss carryforwards 270.1 327.1 Accrued asset retirement obligations 228.0 187.8 Stock-based compensation 7.0 9.2 Unearned revenue 36.7 34.6 Unrealized loss on foreign currency 22.0 4.9 Other accruals and allowances 90.1 83.4 Nondeductible interest 76.2 60.9 Tax credits 82.4 49.3 Items not currently deductible and other 45.4 16.5 Liabilities: Depreciation and amortization (2,128.2) (1,140.3) Right-of-use asset (1,160.7) (824.0) Deferred rent (108.1) (92.9) Investment in affiliate (1) (0.6) (60.4) Other (2.1) (1.1) Subtotal (1,370.0) (507.9) Valuation allowance (329.3) (228.5) Net deferred tax liabilities $ (1,699.3) $ (736.4) _______________ (1) Includes basis difference associated with investment in subsidiary related to the InSite Acquisition. 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 evidence to estimate if sufficient future taxable income will be generated to use the existing deferred tax assets. Valuation allowances may be reversed if, based on changes in facts and circumstances, the net deferred tax assets have been determined to be realizable. At December 31, 2021 and 2020, the Company has provided a valuation allowance of $329.3 million and $228.5 million, respectively, which primarily relates to foreign items. The increase in the valuation allowance for the year ending December 31, 2021 is due to uncertainty as to the timing of, and the Company’s ability to recover, net deferred tax assets in certain foreign operations in the foreseeable future, offset by reversals and fluctuations in foreign currency exchange rates. The amount of deferred tax assets considered realizable, however, could be adjusted if objective evidence in the form of cumulative losses is no longer present and additional weight may be given to subjective evidence such as the Company’s projections for growth. A summary of the activity in the valuation allowance is as follows: 2021 2020 2019 Balance as of January 1, $ 228.5 $ 194.2 $ 151.9 Additions (1) 146.3 64.7 42.5 Usage, expiration and reversals (26.2) (22.0) — Foreign currency translation (19.3) (8.4) (0.2) Balance as of December 31, $ 329.3 $ 228.5 $ 194.2 _______________ (1) Includes net charges to expense and allowances established due to acquisition. The recoverability of the Company’s deferred tax assets has been assessed utilizing projections based on its current operations. Accordingly, the recoverability of the deferred tax assets is not dependent on material asset sales or other non-routine transactions. Based on its current outlook of future taxable income during the carryforward period, the Company believes that deferred tax assets, other than those for which a valuation allowance has been recorded, will be realized. At December 31, 2021, the Company had net federal, state and foreign operating loss carryforwards available to reduce future taxable income. If not utilized, the Company’s NOLs expire as follows: Years ended December 31, Federal State Foreign 2022 to 2026 $ 0.0 $ 260.5 $ 11.7 2027 to 2031 0.0 121.9 45.2 2032 to 2036 23.6 71.7 4.3 2037 to 2041 43.2 245.5 8.6 Indefinite carryforward 281.6 150.8 886.6 Total $ 348.4 $ 850.4 $ 956.4 As of December 31, 2021 and 2020, the total amount of unrecognized tax benefits that would impact the ETR, if recognized, is $94.8 million and $105.9 million, respectively. The amount of unrecognized tax benefits for the year ended December 31, 2021 includes additions to the Company’s existing tax positions of $32.0 million. The Company expects the unrecognized tax benefits to change over the next 12 months if certain tax matters ultimately settle with the applicable taxing jurisdiction during this timeframe, or if the applicable statute of limitations lapses. The impact of the amount of such changes to previously recorded uncertain tax positions could range from zero to $35.1 million. A reconciliation of the beginning and ending amount of unrecognized tax benefits are as follows: Year Ended December 31, 2021 2020 2019 Balance at January 1 $ 136.2 $ 175.6 $ 107.7 Additions based on tax positions related to the current year 7.5 4.7 33.3 Additions and reductions for tax positions of prior years (1) (2) (17.5) (5.0) 37.5 Foreign currency (3.7) (9.6) (1.6) Reduction as a result of the lapse of statute of limitations (4.9) (26.0) (1.3) Reduction as a result of effective settlements (8.8) (3.5) — Balance at December 31 $ 108.8 $ 136.2 $ 175.6 _______________ (1) Year ended December 31, 2021 includes adjustments of $(16.6) million due to a reclassification of unrecognized tax benefits to penalties and income tax-related interest expense. (2) Year ended December 31, 2020 includes adjustments of $(21.0) million for positions related to the Eaton Towers Acquisition that were revised in connection with settlements or effective settlements. During the year ended December 31, 2021, the statute of limitations on certain unrecognized tax benefits lapsed and certain positions were effectively settled, including effective settlements and revisions of prior year positions, which resulted in a decrease of $54.2 million in the liability for unrecognized tax benefits. During the year ended December 31, 2020, the statute of limitations on certain unrecognized tax benefits lapsed and certain positions were effectively settled, including effective settlements and revisions of prior year positions related to the Eaton Towers Acquisition, which resulted in a decrease in the liability for unrecognized tax benefits of $50.5 million. During the year ended December 31, 2019, the statute of limitations on certain unrecognized tax benefits lapsed and certain positions were effectively settled, which resulted in a decrease of $2.5 million in the liability for unrecognized tax benefits. The Company recorded penalties and tax-related interest expense to the tax provision of $69.5 million, $16.4 million and $10.3 million for the years ended December 31, 2021, 2020 and 2019, respectively. During the year ended December 31, 2021, the Company reduced its liability for penalties and income tax-related interest expense related to uncertain tax positions by $14.6 million due to the expiration of the statute of limitations in certain jurisdictions and certain positions that were effectively settled. In addition, as a result of a settlement in the United States, $45.8 million has been reclassified to Accrued income tax payable as of December 31, 2021. During the years ended December 31, 2020 and 2019, the Company reduced its liability for penalties and income tax-related interest expense related to uncertain tax positions by $4.8 million and $2.7 million, respectively, due to the expiration of the statute of limitations in certain jurisdictions and certain positions that were effectively settled. As of December 31, 2021 and 2020, the total amount of accrued income tax-related interest and penalties included in the consolidated balance sheets were $42.3 million and $34.4 million, respectively. |

Share-based Payment Arrangement [Abstract] | |
STOCK-BASED COMPENSATION | STOCK-BASED COMPENSATION 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 Company’s 2007 Equity Incentive Plan, as amended (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 for 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, generally over four years for RSUs and stock options and three years for PSUs. Stock options generally expire 10 years from the date of grant. As of December 31, 2021, the Company had the ability to grant stock-based awards with respect to an aggregate of 5.9 million shares of common stock under the 2007 Plan. In connection with the CoreSite Acquisition, the Company assumed the remaining shares previously available for issuance under a plan approved by the CoreSite shareholders, which converted into 1.4 million shares of the Company’s common stock. These shares will be available for issuance under the 2007 Plan, however, will only be available for grants to certain employees and will not be available for issuance beyond the period when they would have been available under the CoreSite plan, or March 20, 2023, at which time they will no longer be available for grant. In addition, the Company maintains an employee stock purchase plan (the “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 from 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 years ended December 31, 2021, 2020 and 2019, the Company recorded the following stock-based compensation expenses: 2021 (1) 2020 (2) 2019 (2) Stock-based compensation expense $ 119.5 $ 120.8 $ 111.4 _______________ (1) For the year ended December 31, 2021, stock-based compensation expense consisted of $119.5 million, included in selling, general, administrative and development expense.

For the years ended December 31, 2020 and 2019, stock-based compensation expense capitalized as property and equipment was $1.7 million and $1.6 million, respectively. Stock Options —There were no options granted during the years ended December 31, 2021, 2020 and 2019. The fair values of previously granted stock options were estimated on the date of grant using the Black-Scholes option pricing model based on the assumptions at the date of grant. The intrinsic value of stock options exercised during the years ended December 31, 2021, 2020 and 2019 was $176.7 million, $176.3 million and $145.5 million, respectively. As of December 31, 2021, there was no unrecognized compensation expense related to unvested stock options. The amount of cash received from the exercise of stock options was $82.5 million during the year ended December 31, 2021.

PSUs also includes the shares above target that are issuable for the 2019 PSUs at the end of the three-year performance cycle based on exceeding the performance metric for the three-year performance period, or 11,299 shares. (3) As discussed in note 6, pursuant to the terms of the CoreSite Acquisition, the Company issued the CoreSite Replacement Awards. The CoreSite Replacement Awards will continue to vest in accordance with the terms of CoreSite’s equity plan.

Commitments and Contingencies Disclosure [Abstract] | |
COMMITMENTS AND CONTINGENCIES | 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. Verizon Transaction —In March 2015, the Company entered into an agreement with various operating entities of Verizon Communications Inc. (“Verizon”) that currently provides for the lease, sublease or management of approximately 11,250 wireless communications sites 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 rights 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 that tranche. The purchase price for each tranche is a fixed amount stated in the lease 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 2,000 towers commencing between December 2000 and August 2004. Substantially all of the towers are part of the Trust Securitizations. The average term of the lease or sublease for all sites at the inception of the agreement was approximately 27 years, assuming renewals or extensions of the underlying ground leases for the sites. The Company has the option to purchase the sites subject to the applicable lease or sublease upon its expiration. Each tower is assigned to an annual tranche, ranging from 2013 to 2032, which represents the outside expiration date for the sublease rights to that tower. The purchase price for each site is a fixed amount stated in the lease for that site plus the fair market value of certain alterations made to the related tower by AT&T. As of December 31, 2021, the Company has purchased an aggregate of approximately 400 of the subleased towers which are subject to the applicable agreement, including 58 towers purchased during the year ended December 31, 2021 for an aggregate purchase price of $35.3 million. The aggregate purchase option price for the remaining towers leased and subleased is $1.0 billion and includes per annum accretion through the applicable expiration of the lease or sublease of a site. For all such sites, AT&T has the right to continue to lease the reserved space through June 30, 2025 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 five successive five-year terms. Other Contingencies —The Company is subject to income tax and other taxes in the geographic areas where it holds assets or operates, and periodically receives notifications of audits, assessments or other actions by taxing authorities. Taxing authorities may issue notices or assessments while audits are being conducted. In certain jurisdictions, taxing authorities may issue assessments with minimal examination. These notices and assessments do not represent amounts that the Company is obligated to pay and are often not reflective of the actual tax liability for which the Company will ultimately be liable. In the process of responding to assessments of taxes that the Company believes are not enforceable, the Company avails itself of both administrative and judicial remedies. The Company evaluates the circumstances of each notification or assessment based on the information available and, in those instances in which the Company does not anticipate a successful defense of positions taken in its tax filings, a liability is recorded in the appropriate amount based on the underlying assessment. On December 5, 2016, the Company received an income tax assessment of Essar Telecom Infrastructure Private Limited (“ETIPL”) from the India Income Tax Department (the “Tax Department”) for the fiscal year ending 2008 in the amount of INR 4.75 billion ($69.8 million on the date of assessment) related to capital contributions. The Company challenged the assessment before the Office of Commissioner of Income Tax - Appeals, which ruled in the Company’s favor in January 2018. However, the Tax Department has appealed this ruling at a higher appellate authority. The Company estimates that there is a more likely than not probability that the Company’s position will be sustained upon appeal. Accordingly, no liability has been recorded. Additionally, the assessment was made with respect to transactions that took place in the tax year commencing in 2007, prior to the Company’s acquisition of ETIPL. Under the Company’s definitive acquisition agreement with ETIPL, the seller is obligated to indemnify and defend the Company with respect to any tax-related liability that may arise from activities prior to March 31, 2010. Guaranties and Indemnifications —The Company enters into agreements from time to time in the ordinary course of business pursuant to which it agrees to guarantee or indemnify third parties for certain claims. The Company has also entered into purchase and sale agreements relating to the sale or acquisition of assets containing customary indemnification provisions. The Company’s indemnification obligations under these agreements generally are limited solely to damages resulting from breaches of representations and warranties or covenants under the applicable agreements. In addition, payments under such indemnification clauses are generally conditioned on the other party making a claim that is subject to whatever defenses the Company may have and are governed by dispute resolution procedures specified in the particular agreement. Further, the Company’s obligations under these agreements may be limited in duration and amount, and in some instances, the Company may have recourse against third parties for payments made by the Company. The Company has not historically made any material payments under these agreements and, as of December 31, 2021, is not aware of any agreements that could result in a material payment. |

Segment Reporting, Measurement Disclosures [Abstract] | |
Business Segments | BUSINESS SEGMENTSProperty Communications Sites and Related Communications Infrastructure —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. Data Centers —During the fourth quarter of 2021, as a result of the CoreSite Acquisition, the Company established the Data Centers segment as a reportable segment. The Data Centers segment relates to data center facilities and related assets that the Company owns and operates in the United States. The Data Centers segment offers different services from, and requires different resources, skill sets and marketing strategies than, the existing property operating segment in the U.S. & Canada. Prior to this revision, the Company operated in five property business segments: (i) U.S. & Canada property, (ii) Asia-Pacific property (iii) Africa property, (iii) Europe property and (iv) Latin America property. As of December 31, 2021, the Company’s property operations consisted of the following: • U.S. & Canada: property operations in Canada and the United States; • Asia-Pacific: property operations in Australia, Bangladesh, India and the Philippines; • Africa: property operations in Burkina Faso, Ghana, Kenya, Niger, Nigeria, South Africa and Uganda; • Europe: property operations in France, Germany, Poland and Spain; • Latin America: property operations in Argentina, Brazil, Chile, Colombia, Costa Rica, Mexico, Paraguay and Peru; and • Data Centers: data center property operations in the United States. Services —The Company’s Services segment offers tower-related services in the United States, including AZP and structural analysis, which primarily support its site leasing business, including the addition of new tenants and equipment on its sites. The services segment is a strategic business unit that offers different services from, and requires different resources, skill sets and marketing strategies than, the property operating segments. The accounting policies applied in compiling segment information below are similar to those described in note 1. 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. 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 interests 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 consolidated statements of operations and consolidated balance sheets. Summarized financial information concerning the Company’s reportable segments for the years ended December 31, 2021, 2020 and 2019 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 operating expenses; Interest income; Interest expense; Gain (loss) on retirement of long-term obligations; and Other income (expense), and (ii) reconciles segment operating profit to Income from continuing operations before income taxes.

These services include site application, zoning and permitting (“AZP”) and structural analysis, which primarily support the Company’s site leasing business, including the addition of new tenants and equipment on its sites. The Company’s customers include its tenants, licensees and other payers. The Company’s portfolio primarily consists of towers that it owns and towers that it operates pursuant to long-term lease arrangements, as well as distributed antenna system (“DAS”) networks, which provide seamless coverage solutions in certain in-building and outdoor wireless environments. In addition to the communications sites in its portfolio, the Company manages rooftop and tower sites for property owners under various contractual arrangements. The Company also holds other telecommunications infrastructure, fiber and property interests that it leases primarily to communications service providers and third-party tower operators and holds a portfolio of highly interconnected data center facilities and related assets in the United States that the Company leases primarily to enterprises, network operators, cloud providers and supporting service providers. American Tower Corporation is a holding company that conducts its operations through its directly and indirectly owned subsidiaries and 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”). Accordingly, the Company generally is not required to pay U.S. federal income taxes on income generated by its REIT operations, including the income derived from leasing space on its towers and in its data centers, as it receives a dividends paid deduction for distributions to stockholders that generally offsets its REIT income and gains. However, the Company remains obligated to pay U.S. federal income taxes on earnings from its domestic taxable REIT subsidiaries (“TRSs”). In addition, the Company’s international assets and operations, regardless of their classification for U.S. tax purposes, continue to be subject to taxation in the jurisdictions where those assets are held or those operations are conducted. The use of TRSs enables the Company to continue to engage in certain businesses and jurisdictions while complying with REIT qualification requirements. The Company may, from time to time, change the election of previously designated TRSs to be included as part of the REIT. As of December 31, 2021, the Company’s REIT-qualified businesses included its U.S. tower leasing business, a majority of its U.S. indoor DAS networks business, its Services and Data Centers segments, as well as most of its operations in Canada, Costa Rica, France, Germany, Mexico and Nigeria. In January 2022, a majority of the Company’s operations in Ghana, Kenya, South Africa and Uganda became part of the REIT. |
Principles of Consolidation and Basis of Presentation | Principles of Consolidation and Basis of Presentation—The accompanying 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 method or as investments in equity securities, depending upon the Company’s ability to exercise significant influence over operating and financial policies. All intercompany accounts and transactions have been eliminated. |
Change in Reportable Segments | Change in Reportable Segments —During the fourth quarter of 2021, as a result of the Company’s acquisition of CoreSite Realty Corporation (“CoreSite,” and the acquisition, the “CoreSite Acquisition”), the Company updated its reportable segments to add a Data Centers segment. The Data Centers segment is within the Company’s property operations. The Company will now report its results in seven segments – U.S. & Canada property (which includes all assets in the United States and Canada, |
Significant Accounting Policies and Use of Estimates | 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 consolidated financial statements and accompanying notes. Actual results may differ from those estimates, and such differences could be material to the accompanying consolidated financial statements. The significant estimates in the accompanying consolidated financial statements include impairment of long-lived assets (including goodwill), revenue recognition, rent expense and lease accounting, 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. |
Accounts Receivable and Deferred Rent Asset | Accounts Receivable and Deferred Rent Asset —The Company derives the largest portion of its revenues and corresponding accounts receivable and the related deferred rent asset from a relatively small number of customers in the telecommunications industry, and 52% of its current-year revenues are derived from three customers. The Company’s deferred rent asset is associated with non-cancellable tenant leases that contain fixed escalation clauses over the terms of the applicable lease in which revenue is recognized on a straight-line basis over the lease term. The Company mitigates its concentrations of credit risk with respect to notes and trade receivables and the related deferred rent assets by actively monitoring the creditworthiness of its borrowers and customers. In recognizing customer revenue, the Company assesses the collectibility of both the amounts billed and the portion recognized in advance of billing on a straight-line basis. This assessment takes customer credit risk and business and industry conditions into consideration to ultimately determine the collectibility of the amounts billed. To the extent the amounts, based on management’s estimates, may not be collectible, revenue recognition is deferred until such point as collectibility is determined to be reasonably assured. Any amounts that were previously recognized as revenue and are subsequently determined to present a risk of collection are reserved as bad debt expense included in Selling, general, administrative and development expense in the accompanying consolidated statements of operations. |
Functional Currency | Functional Currency —The functional currency of each of the Company’s foreign operating subsidiaries is normally the respective local currency, except for Costa Rica and Argentina, where the functional currency is the U.S. Dollar. All foreign currency assets and liabilities held by the subsidiaries are translated into U.S. Dollars at the exchange rate in effect at the end of the applicable fiscal reporting period and all foreign currency revenues and expenses are translated at the average monthly exchange rates. Translation adjustments are reflected in equity as a component of Accumulated other comprehensive loss |
Cash and Cash Equivalents | Cash and Cash Equivalents —Cash and cash equivalents include cash on hand, demand deposits and short-term investments with original maturities of three months or less. The Company maintains its deposits at high-quality financial institutions and monitors the credit ratings of those institutions. |
Restricted Cash | Restricted Cash— Restricted cash includes cash pledged as collateral to secure obligations and all cash whose use is otherwise limited by contractual provisions. |
Property and Equipment | Property and Equipment —Property and equipment is recorded at cost or, in the case of acquired properties, at estimated fair value on the date acquired. Cost for self-constructed sites includes direct materials and labor and certain indirect costs associated with construction of the site, such as transportation costs, employee benefits and payroll taxes. The Company begins the capitalization of costs during the pre-construction period, which is the period during which costs are incurred to evaluate the site, and continues to capitalize costs until the site is substantially completed and ready for occupancy by a customer. Labor and related costs capitalized for the years ended December 31, 2021, 2020 and 2019 were $59.4 million, $51.1 million and $48.3 million, respectively. Expenditures for repairs and maintenance are expensed as incurred. Augmentation and improvements that extend an asset’s useful life or enhance capacity are capitalized. Depreciation expense is recorded using the straight-line method over the assets’ estimated useful lives. Towers and assets on leased land are depreciated over the shorter of the estimated useful life of the asset or the term of the corresponding ground lease, taking into consideration lease renewal options and residual value. Towers or assets acquired through finance leases are recorded net at the present value of future minimum lease payments or the fair value of the leased asset at the inception of the lease. Property and equipment and assets held under finance leases are amortized over the shorter of the applicable lease term or the estimated useful life of the respective assets for periods generally not exceeding twenty years. The Company reviews its asset portfolio for indicators of impairment on an individual site basis. Impairments primarily result from a site not having current tenant leases or from having expenses in excess of revenues. The Company reviews other long-lived assets for impairment whenever events, changes in circumstances or other evidence indicate that the carrying amount of the Company’s assets may not be recoverable. The Company records impairment charges, which are discussed in note 17, in |
Goodwill and Other Intangible Assets | Goodwill and Other Intangible Assets —The Company reviews goodwill for impairment at least annually (as of December 31) or whenever events or circumstances indicate the carrying value of an asset may not be recoverable. Goodwill is recorded in the applicable segment and assessed for impairment at the reporting unit level. The Company employs a discounted cash flow analysis when testing goodwill for impairment. The key assumptions utilized in the discounted cash flow analysis include current operating performance, terminal sales growth rate, management’s expectations of future operating results and cash requirements, the current weighted average cost of capital and an expected tax rate. The Company compares the fair value of the reporting unit, as calculated under an income approach using future discounted cash flows, to the carrying amount of the applicable reporting unit. If the carrying amount exceeds the fair value, an impairment loss would be recognized for the amount of the excess. The loss recognized is limited to the total amount of goodwill allocated to that reporting unit. During the years ended December 31, 2021, 2020 and 2019, no potential impairment was identified, as the fair value of each of the reporting units was in excess of its carrying amount. Intangible assets that are separable from goodwill and are deemed to have a definite life are amortized over their useful lives, generally ranging from three The Company reviews its network location intangible assets for indicators of impairment on an individual tower basis. Impairments primarily result from a site not having current tenant leases or from having expenses in excess of revenues. The Company monitors its tenant-related intangible assets on a tenant by tenant basis for indicators of impairment, such as high levels of turnover or attrition, non-renewal of a significant number of contracts or the cancellation or termination of a relationship. The Company assesses recoverability by determining whether the carrying amount of the related assets will be recovered primarily through projected undiscounted future cash flows. If the Company determines that the carrying amount of an asset may not be recoverable, the Company measures any impairment loss based on the projected future discounted cash flows to be provided from the asset or available market information relative to the asset’s fair value, as compared to the asset’s carrying amount. The Company records impairment charges, which are discussed in note 17, in Other operating expenses in the consolidated statements of operations in the period in which the Company identifies such impairment. |
Derivatives Financial Instruments | Derivative Financial Instruments —Derivatives are recorded on the consolidated balance sheet at fair value. If a derivative is designated as a cash flow hedge, the effective portions of changes in the fair value of the derivative are recorded in AOCL, as well as a component of comprehensive income, and are recognized in the results of operations when the hedged item affects earnings. Changes in fair value of the ineffective portions of cash flow hedges are recognized in the results of operations. For derivative instruments that are designated and qualify as fair value hedges, changes in value of the derivatives are recorded in Other expense in the consolidated statements of operations in the current period, along with the offsetting gain or loss on the hedged item attributable to the hedged risk. For derivative instruments not designated as hedging instruments, changes in fair value are recognized in the results of operations in the period that the change occurs. The primary risks managed through the use of derivative instruments is interest rate risk, exposure to changes in the fair value of debt attributable to interest rate risk and currency risk. From time to time, the Company enters into interest rate swap agreements or foreign currency contracts to manage exposure to these risks. Under these agreements, the Company is exposed to counterparty credit risk to the extent that a counterparty fails to meet the terms of a contract. The Company’s exposure is limited to the current value of the contract at the time the counterparty fails to perform. The Company assesses, both at the inception of the hedge and on an ongoing basis, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in cash flows or fair values of hedged items. The Company does not hold derivatives for trading purposes. |
Fair Value Measurements | 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. |
Asset Retirement Obligations | Asset Retirement Obligations —When required, the Company recognizes the fair value of obligations to remove its assets and remediate the leased space upon which certain of its assets are located. Generally, the associated retirement costs are capitalized as part of the carrying amount of the related assets and depreciated over their estimated useful lives and the liability is accreted through the obligation’s estimated settlement date. Fair value estimates of asset retirement obligations generally involve discounting of estimated future cash flows associated with remediation costs. Periodic accretion of such liabilities due to the passage of time is included in Depreciation, amortization and accretion expense in the consolidated statements of operations. |
Income Taxes | Income Taxes —As a REIT, the Company generally is not subject to U.S. federal income taxes on income generated by its REIT operations as it receives a dividends paid deduction for distributions to stockholders that generally offsets its REIT income and gains. However, the Company remains obligated to pay U.S. federal income taxes on certain earnings and continues to be subject to taxation in its foreign jurisdictions. Accordingly, the consolidated financial statements reflect provisions for federal, state, local and foreign income taxes. The Company recognizes deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis, as well as operating loss and tax credit carryforwards. The Company measures deferred tax assets and liabilities using enacted tax rates expected to apply to taxable income in the years in which those temporary differences and carryforwards are expected to be recovered or settled. The effect on deferred tax assets and liabilities as a result of a change in tax rates is recognized in income in the period that includes the enactment date. The Company periodically reviews its deferred tax assets, and 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. Valuation allowances would be reversed as a reduction to the provision for income taxes if related deferred tax assets are deemed realizable based on changes in facts and circumstances relevant to the assets’ recoverability. The Company estimates the liabilities from uncertain tax positions, which are recorded in Other non-current liabilities in the consolidated balance sheet, unless expected to be paid within one year. The Company reports penalties and tax-related interest expense as a component of the income tax provision and interest income from tax refunds as a component of Interest income in the consolidated statements of operations. |
Other Comprehensive Income (Loss) | Other Comprehensive Income (Loss)—Other comprehensive income (loss) refers to items excluded from net income that are recorded as an adjustment to equity, net of tax. The Company’s other comprehensive income (loss) primarily consisted of changes in fair value of effective derivative cash flow hedges, foreign currency translation adjustments and reclassification of unrealized losses on effective derivative cash flow hedges. |
Distributions | Distributions —As a REIT, the Company must annually distribute to its stockholders an amount equal to at least 90% of its REIT taxable income (determined before the deduction for distributed earnings and excluding any net capital gain). Generally, the Company has distributed, and expects to continue to distribute, all or substantially all of its REIT taxable income after taking into consideration its utilization of net operating losses (“NOLs”). The amount, timing and frequency of future distributions will be at the sole discretion of the Board of Directors and will depend upon various factors, a number of which may be beyond the Company’s control, including the Company’s financial condition and operating cash flows, the amount required to maintain its qualification for taxation as a REIT and reduce any income and excise taxes that the Company otherwise would be required to pay, limitations on distributions in the Company’s existing and future debt and preferred equity instruments, the Company’s ability to utilize NOLs to offset the Company’s distribution requirements, limitations on its ability to fund distributions using cash generated through its TRSs and other factors that the Board of Directors may deem relevant. |
Acquisitions | Acquisitions —For acquisitions that meet the definition of a business combination, the Company applies the acquisition method of accounting where assets acquired and liabilities assumed are recorded at fair value at the date of each acquisition, and the results of operations are included with those of the Company from the dates of the respective acquisitions. Any excess of the purchase price paid by the Company over the amounts recognized for assets acquired and liabilities assumed is recorded as goodwill. The Company continues to evaluate acquisitions for a period not to exceed one year after the applicable acquisition date of each transaction to determine whether any additional adjustments are needed to the allocation of the purchase price paid for the assets acquired and liabilities assumed. All other acquisitions are accounted for as asset acquisitions and the purchase price is allocated to the net assets acquired with no recognition of goodwill. The purchase price is not subsequently adjusted. The fair value of the assets acquired and liabilities assumed is typically determined by using either estimates of replacement costs or discounted cash flow valuation methods. When determining the fair value of tangible assets acquired, the Company must estimate the cost to replace the asset with a new asset taking into consideration such factors as age, condition and the |
Revenue | Revenue —The Company’s revenue is derived from leasing the right to use its communications sites, the land on which the sites are located and its data center facilities (the “lease component”) and from the reimbursement of costs incurred by the Company in operating the communications sites and data center facilities and supporting its customers’ equipment as well as other services and contractual rights (the “non-lease component”). Most of the Company’s revenue is derived from leasing arrangements and is accounted for as lease revenue unless the timing and pattern of revenue recognition of the non-lease component differs from the lease component. If the timing and pattern of the non-lease component revenue recognition differs from that of the lease component, the Company separately determines the stand-alone selling prices and pattern of revenue recognition for each performance obligation. Revenue related to DAS networks and fiber and other related assets results from agreements with tenants are generally not accounted for as leases. The Company’s revenue from leasing arrangements, including fixed escalation clauses present in non-cancellable lease arrangements, is reported on a straight-line basis over the term of the respective leases when collectibility is probable. Escalation clauses tied to a consumer price index (“CPI”), or other inflation-based indices, and other incentives present in lease agreements with the Company’s tenants are excluded from the straight-line calculation. Total property straight-line revenues for the years ended December 31, 2021, 2020 and 2019 were $465.6 million, $322.0 million and $183.5 million, respectively. Non-lease property revenue— Non-lease property revenue consists primarily of revenue generated from DAS networks, fiber and other property related revenue. DAS networks and fiber arrangements generally require that the Company provide the tenant the right to use available capacity on the applicable communications infrastructure. Performance obligations are satisfied over time for the duration of the arrangements. Non-lease property revenue also includes revenue generated from interconnection services in the Company’s data center facilities. Interconnection services are generally contracted on a month-to-month basis and are cancellable by the Company or the data center customer at any time. Performance obligations are satisfied over time for the duration of the arrangements. Other property related revenue streams, which include site inspections, are not material on either an individual or consolidated basis. Services revenue— The Company offers tower-related services in the United States. These services include AZP and structural analysis. There is a single performance obligation related to AZP and revenue is recognized over time based on milestones achieved, which are determined based on costs expected to be incurred. Structural analysis services may have more than one performance obligation, contingent upon the number of contracted services. Revenue is recognized at the point in time the services are completed. Some of the Company’s contracts with customers contain multiple performance obligations. For these arrangements, the Company allocates revenue to each performance obligation based on its relative standalone selling price, which is typically based on the price charged to customers. Since most of the Company’s contracts are leases, costs to enter into lease arrangements are capitalized under the applicable lease accounting guidance. Costs incurred to obtain non-lease contracts that are capitalized primarily relate to DAS networks and are not material to the consolidated financial statements. The Company has excluded sales tax, value added tax and similar taxes from non-lease revenue. The Company records unearned revenue when payments are received from customers in advance of the completion of the Company’s performance obligations. Long-term unearned revenue is included in Other non-current liabilities. During the year ended December 31, 2021, the Company recognized $169.3 million of revenue that was previously included in the contract liabilities balances, primarily arising from balances as of December 31, 2020. The Company records unbilled receivables, which are included in Prepaids and other current assets, when it has completed a performance obligation prior to its ability to bill under the customer arrangement. Other contract assets are included in Notes receivable and other non-current assets. The Company recorded an immaterial change in unbilled receivables attributable to non-lease property revenue recognized during each of the years ended December 31, 2021 and 2020. The change in contract assets attributable to revenue recognized during the years ended December 31, 2021 and 2020 was $2.2 million and $6.8 million, respectively. |
Lease Accounting and Rent Expense | Lease Accounting and Rent Expense —The Company accounts for leases using a right-of-use model, which recognizes that, at the date of commencement, a lessee has a financial obligation to make lease payments to the lessor for the right to use the underlying asset during the lease term. The lessee recognizes a corresponding right-of-use asset related to this right. The Company recognizes a right-of-use lease asset and lease liability for operating and finance leases. The right-of-use asset is measured as the sum of the lease liability, prepaid or accrued lease payments, any initial direct costs incurred and any other applicable amounts. The Company reviews its right-of-use assets for impairment whenever events, changes in circumstances or other evidence indicate that the carrying amount of the Company’s assets may not be recoverable. The Company reviews its right-of-use assets for indicators of impairment at the lowest level of identifiable cash flows, as part of its asset portfolio. Impairments primarily result from a site not having current tenant leases or from having expenses in excess of revenues. The Company records impairment charges, which are discussed in note 17, in Other operating expenses in the consolidated statements of operations in the period in which the Company identifies such impairment. The calculation of the lease liability requires the Company to make certain assumptions for each lease, including lease term and discount rate implicit in each lease, which could significantly impact the gross lease obligation, the duration and the present value of the lease liability. When calculating the lease term, the Company considers the renewal, cancellation and termination rights available to the Company and the lessor. The Company determines the discount rate by calculating the incremental borrowing rate on a collateralized basis at the commencement of a lease or upon a change in the lease term. Many of the leases underlying the Company’s sites have fixed rent escalations, which provide for periodic increases in the amount of ground rent payable by the Company over time. In addition, certain of the Company’s tenant leases require the Company to exercise available renewal options pursuant to the underlying ground lease if the tenant exercises its renewal option. The Company’s calculation of the lease liability includes the term of the underlying ground lease plus all periods, if any, for which failure to renew the lease imposes an economic penalty to the Company such that renewal appears to be reasonably assured. |
Selling, General, Administrative and Development Expense | Selling, General, Administrative and Development Expense —Selling, general and administrative expense consists of overhead expenses related to the Company’s property and services operations and corporate overhead costs not specifically allocable to any of the Company’s individual business operations. Development expense consists of costs related to the Company’s acquisition efforts, costs associated with new business initiatives and project cancellation costs. |
Stock-Based Compensation | Stock-Based Compensation —Stock-based compensation expense is measured at the accounting measurement date based on the fair value of the award and is generally recognized as an expense over the service period, which typically represents the vesting period. The Company 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, the Company recognizes compensation expense for stock options and time-based restricted stock units (“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 benefits due to death, disability or qualified retirement, which may occur upon grant. The expense recognized includes the impact of forfeitures as they occur. The Company grants performance-based restricted stock units (“PSUs”) to its executive officers. Threshold, target and maximum parameters are established for a three-year performance period at the time of grant. The metrics are used to calculate the number of shares that will be issuable when the awards vest, which may range from zero to 200% of the target amounts. The Company recognizes compensation expense for PSUs over the three-year vesting period, subject to adjustment based on the date the employee becomes eligible for retirement benefits as well as performance relative to grant parameters. The fair value of stock options is determined using the Black-Scholes option-pricing model and the fair value of RSUs and PSUs is based on the fair value of the Company’s common stock on the date of grant. The Company recognizes all stock-based compensation expense in either Selling, general, administrative and development expense, costs of operations or as part of the costs associated with the construction of assets. |
Litigation Costs | Litigation Costs —The Company periodically becomes involved in various claims and lawsuits that are incidental to its business. The Company regularly monitors the status of pending legal actions to evaluate both the magnitude and likelihood of any potential loss. The Company accrues for these potential losses when it is probable that a liability has been incurred and the amount of loss, or possible range of loss, can be reasonably estimated. Should the ultimate losses on contingencies or litigation vary from estimates, adjustments to those liabilities may be required. The Company also incurs legal costs in connection with these matters and records estimates of these expenses, which are reflected in Selling, general, administrative and development expense in the accompanying consolidated statements of operations. |
Earnings Per Common Share-Basic and Diluted | Earnings Per Common Share — Basic and Diluted —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 (A) shares issuable upon the vesting of RSUs and exercise of stock options and |
Retirement Plan | Retirement Plan—The Company has a 401(k) plan covering nearly all eligible employees who meet certain age and employment requirements. |
Accounting Standards Updates | Accounting Standards Updates In March 2020, the Financial Accounting Standards Board (the “FASB”) issued guidance to provide optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. The guidance applies only to contracts, hedging relationships and other transactions that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the guidance do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022 for which an entity has elected certain optional expedients that are retained through the end of the hedging relationship. In January 2021, the FASB issued additional guidance that clarifies that certain practical expedients and exceptions for contract modifications and hedge accounting apply to derivatives that are affected by reference rate reform. As of December 31, 2021, the Company has not modified any contracts as a result of reference rate reform and is evaluating the impact this standard may have on its consolidated financial statements. |
