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, inclusive of its data center business discussed below, 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”), structural and mount analyses and construction management, 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 provides for the leasing of space 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 offsets its REIT taxable 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, 2023, 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, Ghana, Kenya, Mexico, Nigeria, South Africa and Uganda. 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, 2023, the Company holds (i) a 52% controlling interest in subsidiaries whose holdings consist of the Company’s operations in France, Germany and Spain (such subsidiaries collectively, “ATC Europe”) (Allianz and CDPQ (each as defined in note 15) hold the noncontrolling interests), (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) and (iii) a common equity interest of approximately 72% in the Company’s U.S. data center business (Stonepeak (as defined and further discussed in note 15) holds approximately 28% of the outstanding common equity and 100% of the outstanding mandatorily convertible preferred equity). As of December 31, 2023, 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 15 for a discussion of changes to the Company’s noncontrolling interests during the years ended December 31, 2023 and 2022. Sale of Mexico Fiber — On March 29, 2023, the Company completed the sale of one of its subsidiaries in Mexico that held fiber assets (“Mexico Fiber”) for total consideration of $252.5 million, resulting in a loss on the sale of $80.0 million, which was included in Other operating expenses Sale of Poland Subsidiary —On May 31, 2023, the Company completed the sale of its subsidiary in Poland (“ATC Poland”) for total consideration of 6.7 million EUR (approximately $7.2 million at the date of closing), resulting in a gain on the sale of $1.1 million, which was included in Other operating expenses in the accompanying consolidated statements of operations. Prior to the divestiture, ATC Poland’s operating results were included within the Europe property segment. The divestiture did not qualify for presentation as a discontinued operation. Reportable Segments —The Company reports 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 20. 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 45% 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 for 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, 2023 2022 2021 Balance as of January 1, $ 438.7 $ 355.9 $ 247.6 Current year increases 120.6 168.2 130.9 Write-offs, recoveries and other (73.2) (85.4) (22.6) Balance as of December 31, $ 486.1 $ 438.7 $ 355.9 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, 2023 2022 2021 Foreign currency (gains) losses recorded in AOCL $ (103.9) $ 336.7 $ 466.5 Foreign currency losses (gains) recorded in Other expense 330.8 (449.4) (557.9) Total foreign currency losses (gains) $ 226.9 $ (112.7) $ (91.4) Adoption of Highly Inflationary Accounting in Ghana— The Ghanaian economy was deemed to be highly inflationary and, as a result, the Company will adopt highly inflationary accounting as of January 1, 2024 for its subsidiary in Ghana. Under highly inflationary accounting, the functional currency of its subsidiary in Ghana will become the U.S. Dollar. All monetary and non-monetary assets and liabilities will be remeasured at the U.S. Dollar to Ghanaian Cedis exchange rate of 1 to 11.95 as of December 31, 2023. These amounts will become the new basis for those assets and liabilities as of January 1, 2024. Non-monetary assets and liabilities, as well as the corresponding income statement activities such as depreciation, amortization and equity, will continue to be measured at the historical exchange rate on December 31, 2023. Gains and losses on foreign currency arising in connection with the remeasurement of local currency denominated monetary assets and liabilities for foreign operating subsidiaries in economies that are deemed to be highly inflationary are reflected in Other expense in the consolidated statements of operations. This change is not expected to have a material impact on the Company’s financial statements, as Ghana’s assets and revenue are approximately 1% and 1% of consolidated assets and revenue, respectively. 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, 2023 2022 2021 Cash and cash equivalents $ 1,973.3 $ 2,028.4 $ 1,949.9 Restricted cash 120.1 112.3 393.4 Total cash, cash equivalents and restricted cash $ 2,093.4 $ 2,140.7 $ 2,343.3 Restricted cash as of December 31, 2021 included 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, 2023, 2022 and 2021 were $64.4 million, $65.2 million and $59.4 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 estimated useful life of the asset taking into consideration the term of the corresponding ground lease 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 16, in Other operating expenses in the consolidated statements of operations in the period in which the Company identifies such impairment. The Company is in the process of finalizing its review of the estimated useful lives of its tower assets. The Company now has over 20 years of operating history, and it is considering whether it should modify its current estimates for asset lives based on its historical operating experience. The Company has retained an independent consultant to assist the Company in completing this review and analysis. The Company currently depreciates its towers on a straight-line basis over the shorter of the term of the underlying ground lease (including renewal options) taking into account residual value or the estimated useful life of the tower, which the Company has historically estimated to be 20 years. Additionally, certain of the Company’s intangible assets are amortized on a similar basis to its tower assets, as the estimated useful lives of such intangible assets correlate to the useful life of the towers. If the Company concludes that a revision in the estimated useful lives of its tower assets is appropriate based on its review and analysis, which the Company expects to conclude in 2024, the Company will account for any changes in the useful lives as a change in accounting estimate under ASC 250 Accounting Changes and Error Corrections, which will be recorded prospectively beginning in the period of change. Based on preliminary information obtained to date, the Company expects that its estimated asset lives may be extended, which would result in an estimated (i) $700 million to $800 million decrease in depreciation and amortization for the year ended December 31, 2024 and (ii) $450 million to $550 million increase in the right of use asset, as additional renewal options may be included, with an offsetting adjustment made to increase the related operating lease liability. 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 revenue 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 year ended December 31, 2023, the Company concluded that a triggering event occurred with respect to its India reporting unit. As a result, the Company performed a goodwill impairment test based on information observed during its review of strategic alternatives for this reporting unit. The result of the Company’s goodwill impairment test indicated that the carrying amount of the Company's India reporting unit exceeded its estimated fair value. As a result, the Company recorded a goodwill impairment charge of $322.0 million during the quarter ended September 30, 2023. The Company also performed its annual goodwill impairment test as of December 31, 2023. The results of the annual goodwill impairment test indicated that the carrying amount of the Company’s Spain reporting unit exceeded its estimated fair value. As a result, the Company recorded a goodwill impairment charge of $80.0 million. The goodwill impairment charges are recorded in Goodwill impairment in the accompanying consolidated statements of operations. During the years ended December 31, 2023, 2022 and 2021, no other goodwill 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 two 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, the customer’s ability to meet its contractual obligations, 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 16, in Other operating expenses in the consolidated statements of operations in the period in which the Company identifies such impairment. 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. The Company is in the process of finalizing its review of the estimated settlement dates for its asset retirement obligations. The Company now has over 20 years of operating history, and it is considering whether it should modify its current estimated settlement dates based on its historical operating experience, management’s intent with respect to the assets, and the assets’ estimated useful lives. The Company expects to complete its review of estimated settlement dates in the first quarter of 2024. If the Company concludes that a revision in the estimated settlement dates for its asset retirement obligations is appropriate based on its review and analysis, the Company will account for any changes in the estimated settlement dates as a change in accounting estimate under ASC 250 Accounting Changes and Error Corrections, which will be recorded prospectively beginning in the period of change. Based on preliminary information obtained to date, the Company expects that its estimated settlement dates may be extended. The extension in the estimated settlement dates would result in an estimated (i) $400 million to $500 million increase in the asset retirement obligation liability, with an offsetting adjustment made to the related long-lived tangible asset, (ii) $800 million to $900 million increase in the estimated undiscounted future cash outlay for asset retirement obligations, and (iii) $50 million to $100 million decrease in estimated accretion expense for the year ended December 31, 2024. 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, reclassification of unrealized losses on effective derivative cash flow hedges and other items. The AOCL balance included accumulated foreign currency translation losses of $5.7 billion, $5.7 billion and $4.7 billion as of December 31, 2023, 2022 and 2021, 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 timing and amount of future cash flows, including rate and terms of renewal and attrition, and apply the applicable discount rate. Revenue —The Company’s revenue is derived from leasing the right to use its communications sites, the land on which the sites are located, land underlying our customers’ sites and the space in 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 customers that 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, 2023, 2022 and 2021 were $472.0 million, $499.8 million and $465.6 million, respectively.

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 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, 2023, 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. If incentives are present in the Company’s leases, 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 and amortized on a straight line basis over the corresponding lease term as a non-cash reduction to revenue. As of December 31, 2023, the remaining weighted average amortization period of the Company’s lease incentives wa s 10 years . As of December 31, 2023, Other current assets and Other non-current assets include $31.8 million and $345.7 million, respectively, for lease incentives. In addition, the Company’s leases do not include any lessee purchase options. Historically, the Company has been able to successfully renew its applicable leases as needed to ensure continuation of its revenue. Accordingly, the Company assumes that it will have access to the communications infrastructure or ground space underlying its sites when calculating future minimum rental receipts through the end of the respective terms. Future minimum rental receipts expected under non-cancellable operating lease agreements as of December 31, 2023, were as follows: Fiscal Year Amount (1) (2) 2024 $ 8,233.1 2025 7,643.1 2026 7,191.7 2027 6,995.2 2028 5,686.7 Thereafter 24,525.6 Total $ 60,275.4 _______________ (1) Balances are translated at the applicable period-end exchange rate, which may impact comparability between periods. (2) Balances represent contractual amounts owned with no adjustments made for expected collectibility. 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, 2023, 2022 and 2021, the Company recorded $6.7 million, $8.1 million and $3.3 million, respectively, of impairment expense related to these assets. As of December 31, 2023, 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, 2023, 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, 2023 December 31, 2022 Operating leases: Right-of-use asset $ 8,878.8 $ 8,918.9 Current portion of lease liability $ 794.6 $ 788.9 Lease liability 7,438.7 7,591.9 Total operating lease liability $ 8,233.3 $ 8,380.8 Finance leases: Current portion of lease liability $ 3.4 $ 4.7 Lease liability 17.2 23.1 Total finance lease liability $ 20.6 $ 27.8 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, 2023 December 31, 2022 Operating leases: Weighted-average remaining lease term (years) 11.6 12.2 Weighted-average incremental borrowing rate 5.8 % 5.3 % Finance leases: Weighted-average remaining lease term (years) 16.2 13.4 Weighted-average incremental borrowing rate 7.4 % 6.9 % The following table sets forth the components of lease cost for the years ended December 31,: 2023 2022 2021 Operating lease cost $ 1,249.7 $ 1,222.8 $ 1,115.1 Variable lease costs not included in lease liability (1) 447.2 388.2 339.6 _______________ (1) Primarily includes property tax paid on behalf of the landlord. The interest expense on finance lease liabilities was $1.1 million, $1.1 million and $1.2 million for the years ended December 31, 2023, 2022 and 2021, respectively.

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 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.

Data Centers consists of measurement period adjustments related to the CoreSite Acquisition (as defined in note 6). (2) Other represents the goodwill associated with certain operations acquired in connection with the acquisition of InSite Wireless Group, LLC (the “InSite Acquisition”). These business operations were sold during the year ended December 31, 2022. (3) Other represents the goodwill associated with Mexico Fiber, which was sold during the year ended December 31, 2023. (4) Includes $322.0 million and $80.0 million of goodwill impairments associated with the India and Spain reporting units, respectively. Goodwill Impairments The Company reviews goodwill for impairment annually (as of December 31) or whenever events or circumstances indicate the carrying amount of an asset may not be recoverable, as further discussed in note 1. The Company concluded that a triggering event occurred during the year ended December 31, 2023 with respect to its India reporting unit primarily due to indications of value received from third parties in connection with the Company’s review of various strategic alternatives for its India operations, which concluded in the Pending ATC TIPL Transaction (as defined in note 22) in January 2024 . As a result, the Company performed a goodwill impairment test using, among other things, the information obtained from third parties to compare the estimated fair value of the India reporting unit to its carrying amount, including goodwill. The result of the Company’s goodwill impairment test indicated that the carrying amount of the Company's India reporting unit exceeded its estimated fair value. As a result, the Company recorded a goodwill impairment charge of $322.0 million. The Company also performed its annual goodwill impairment test as of December 31, 2023. The results of the annual goodwill impairment test indicated that the carrying amount of the Company’s Spain reporting unit exceeded its estimated fair value, as calculated under an income approach using future discounted cash flows. As a result, the Company recorded a goodwill impairment charge of $80.0 million. The key assumptions utilized in the discounted cash flow analysis include current operating performance, terminal revenue 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 reduction in the fair value of the Spain reporting unit was primarily due to an increase in the weighted average cost of capital. The goodwill impairment charges are recorded in Goodwill impairment in the accompanying consolidated statements of operations. The Company’s other intangible assets subject to amortization consisted of the following: As of December 31, 2023 As of December 31, 2022 Estimated Useful Gross Accumulated Net Book Gross Accumulated Net Book Acquired network location intangibles (1) Up to 20 $ 5,981.5 $ (2,775.8) $ 3,205.7 $ 6,058.2 $ (2,537.9) $ 3,520.3 Acquired tenant-related intangibles Up to 20 18,894.5 (6,698.6) 12,195.9 18,941.2 (5,827.7) 13,113.5 Acquired licenses and other intangibles 2-20 1,561.1 (442.0) 1,119.1 1,772.9 (423.4) 1,349.5 Total other intangible assets $ 26,437.1 $ (9,916.4) $ 16,520.7 $ 26,772.3 $ (8,789.0) $ 17,983.3 _______________ (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. 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 place lease 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 intangible assets on a straight-line basis over their estimated useful lives. As of December 31, 2023, 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, 2023, 2022 and 2021 was $1.4 billion, $1.7 billion and $1.2 billion, respectively. Based on current exchange rates, the Company expects to record amortization expense as follows over the next five years: Fiscal Year Amount 2024 $ 1,334.1 2025 1,275.1 2026 1,231.7 2027 1,216.2 2028 1,204.9 |

Business Combinations [Abstract] | |
ACQUISITIONS | ACQUISITIONS The Company evaluates each of its acquisitions under the accounting guidance framework to determine whether to treat an acquisition as an asset acquisition or a business combination. 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 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, acquisitions may also include data center facilities and related assets. 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, 2023 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. Communications 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, disposition 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, disposition and merger related expenses not subject to capitalization, as well as integration costs for all transactions, in Other operating expenses in the consolidated statements of operations. During the years ended December 31, 2023, 2022 and 2021, the Company recorded acquisition, disposition and merger related expenses for business combinations, dispositions and non-capitalized asset acquisition costs and integration costs as follows: Year Ended December 31, 2023 2022 2021 Acquisition, disposition and merger related expenses $ 17.6 $ 57.0 $ 177.0 Integration costs $ 16.4 $ 45.0 $ 50.4 During the years ended December 31, 2023, 2022 and 2021, the Company recorded net benefits of $10.3 million, $15.1 million and $17.6 million related to pre-acquisition contingencies and settlements, respectively. The year ended December 31, 2022 included acquisition and merger related costs associated with the Stonepeak Transaction (as defined in note 15). The year ended December 31, 2021 included acquisition and merger related costs associated with the Telxius Acquisition and the CoreSite Acquisition (each as defined below). 2023 Transactions The estimated aggregate impact of the acquisitions completed in 2023 on the Company’s revenues and gross margin for the year ended December 31, 2023 was not material to the Company’s operating results. Acquisitions completed in 2023 were included in the applicable Company property segments. Other Acquisitions— During the year ended December 31, 2023, the Company acquired a total of 159 communications sites, as well as other communications infrastructure assets, in the United States, Canada, France, Poland and Spain for an aggregate purchase price of $109.4 million. Of the aggregate purchase price, $30.8 million, inclusive of value-added tax, is reflected as a payable in the consolidated balance sheet as of December 31, 2023. These acquisitions were 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 2023 acquisitions based upon their estimated fair value at the date of acquisition: Other Current assets $ 11.0 Property and equipment 57.5 Intangible assets (1): Tenant-related intangible assets 35.3 Network location intangible assets 7.9 Other non-current assets 3.4 Current liabilities (0.8) Other non-current liabilities (4.9) Net assets acquired 109.4 Fair value of net assets acquired 109.4 Purchase price $ 109.4 ______________ (1) Tenant-related intangible assets and network location intangible assets are amortized on a straight-line basis over the estimated useful lives of the assets. In addition to the acquisitions discussed above, during the year ended December 31, 2023, the Company purchased 59 towers in connection with the AT&T transaction described in note 18 for an aggregate purchase price of $40.9 million. Telxius and CoreSite Acquisitions 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 EUR (approximately $9.4 billion at the date of signing) (the “Telxius Acquisition”), subject to certain 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. 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.

(2) Accrued and unpaid interest on USD denominated notes is payable in USD semi-annually in arrears and will be computed from the issue date on the basis of a 360-day year comprised of twelve 30-day months. Interest on EUR denominated notes is payable in EUR annually in arrears and will be computed on the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from and including the last date on which interest was paid on the notes, beginning on the issue date. (3) The Company may redeem the notes at any time, in whole or in part, at a redemption price equal to 100% of the principal amount of the notes plus a make-whole premium, together with accrued interest to the redemption date. If the Company redeems the notes on or after the par call date, the Company will not be required to pay a make-whole premium. (4) The original issue date for the initial 5.00% Notes was August 19, 2013. The issue date for the reopened 5.00% Notes was January 10, 2014. (5) Notes are denominated in EUR. (6) The original issue date for the initial 3.100% Notes was June 3, 2020. The issue date for the reopened 3.100% Notes was September 28, 2020. (7) The original issue date for the initial 2.950% Notes was November 20, 2020. The issue date for the reopened 2.950% Notes was September 27, 2021. The Company may redeem each series of senior notes at any time, subject to the terms of the applicable supplemental indenture, in whole or in part, at a redemption price equal to 100% of the principal amount of the notes plus a make-whole premium, as applicable, together with accrued interest to the redemption date. In addition, if the Company undergoes a change of control and corresponding ratings decline, each as defined in the applicable supplemental indenture for the notes, the Company may be required to repurchase all of the applicable notes at a purchase price equal to 101% of the principal amount of such notes, plus accrued and unpaid interest (including additional interest, if any), up to but not including the repurchase date. The notes rank equally with all of the Company’s other senior unsecured debt and are structurally subordinated to all existing and future indebtedness and other obligations of its subsidiaries. Each applicable supplemental indenture for the notes contains certain covenants that restrict the Company’s ability to merge, consolidate or sell assets and its (together with its subsidiaries’) ability to incur liens. These covenants are subject to a number of exceptions, including that the Company and its subsidiaries may incur certain liens on assets, mortgages or other liens securing indebtedness if the aggregate amount of indebtedness secured by such liens does not exceed 3.5x Adjusted EBITDA, as defined in the applicable supplemental indenture. As of December 31, 2023, the Company was in compliance with each of these covenants. American Tower Subsidiary Debt Securitizations The Company has several securitizations in place. Cash flows generated by the communications sites that secure the securitized debt of the Company are only available for payment of such debt and are not available to pay the Company’s other obligations or the claims of its creditors. However, subject to certain restrictions, the Company holds the right to receive the excess cash flows not needed to service the securitized debt and other obligations arising out of the securitizations. The securitized debt is the obligation of the issuers thereof or borrowers thereunder, as applicable, and their subsidiaries, and not of the Company or its other subsidiaries. American Tower Secured Revenue Notes, Series 2015-1, Class A and Series 2015-2, Class A —In May 2015, GTP Acquisition Partners I, LLC (“GTP Acquisition Partners”), one of the Company’s wholly owned subsidiaries, refinanced existing debt with cash on hand and proceeds from a private issuance (the “2015 Securitization”) of $350.0 million of American Tower Secured Revenue Notes, Series 2015-1, Class A, which were subsequently repaid on the June 2020 payment date, and $525.0 million of American Tower Secured Revenue Notes, Series 2015-2, Class A (the “Series 2015-2 Notes”). The Series 2015-2 Notes were issued by GTP Acquisition Partners pursuant to a Third Amended and Restated Indenture and related series supplements, each dated as of May 29, 2015 (collectively, the “2015 Indenture”), between GTP Acquisition Partners and its subsidiaries (the “GTP Entities”) and The Bank of New York Mellon, as trustee. The effective weighted average life and interest rate of the 2015 Notes was 8.1 years and 3.029%, respectively, as of the date of issuance. The outstanding Series 2015-2 Notes are secured by (i) mortgages, deeds of trust and deeds to secure debt on substantially all of the 3,343 communications sites (the “2015 Secured Sites”) owned by the GTP Entities and their operating cash flows, (ii) a security interest in substantially all of the personal property and fixtures of the GTP Entities, including GTP Acquisition Partners’ equity interests in its subsidiaries and (iii) the rights of the GTP Entities under a management agreement. American Tower Holding Sub II, LLC, whose only material assets are its equity interests in GTP Acquisition Partners, has guaranteed repayment of the Series 2015-2 Notes and pledged its equity interests in GTP Acquisition Partners as security for such payment obligations. Repayment of Series 2013-2A Securities —On the March 2023 repayment date, the Company repaid the entire $1.3 billion aggregate principal amount outstanding under the Company’s Secured Tower Revenue Securities, Series 2013-2A due 2023 (the “Series 2013-2A Notes”), pursuant to the terms of the agreements governing such securities. The repayment was funded with proceeds from the 2023 Securitization (as defined below). Secured Tower Revenue Securities, Series 2023-1, Subclass A and Series 2023-1, Subclass R, Series 2018-1, Subclass A and Series 2018-1, Subclass R —On March 13, 2023, the Company completed a securitization transaction (the “2023 Securitization”), in which American Tower Trust I (the “Trust”) issued $1.3 billion aggregate principal amount of Secured Tower Revenue Securities, Series 2023-1, Subclass A (the “Series 2023-1A Securities”). To satisfy the applicable risk retention requirements of Regulation RR promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act” and, such requirements, the “Risk Retention Rules”), the Trust issued, and one of the Company’s affiliates purchased, $68.5 million aggregate principal amount of Secured Tower Revenue Securities, Series 2023-1, Subclass R (the “Series 2023-1R Securities” and, together with the Series 2023-1A Securities, the “2023 Securities”) to retain an “eligible horizontal residual interest” (as defined in the Risk Retention Rules) in an amount equal to at least 5% of the fair value of the 2023 Securities. On March 29, 2018, the Company completed a securitization transaction (the “2018 Securitization,” and, together with the 2023 Securitization, the “Trust Securitizations”), in which the Trust issued $500.0 million aggregate principal amount of Secured Tower Revenue Securities, Series 2018-1, Subclass A (the “Series 2018-1A Securities”). To satisfy the Risk Retention Rules, the Trust issued, and one of the Company’s affiliates purchased, $26.4 million aggregate principal amount of Secured Tower Revenue Securities, Series 2018-1, Subclass R (the “Series 2018-1R Securities” and, together with the Series 2018-1A Securities, the “2018 Securities”) to retain an “eligible horizontal residual interest” (as defined in the Risk Retention Rules) in an amount equal to at least 5% of the fair value of the 2018 Securities. The assets of the Trust consist of a nonrecourse loan broken into components or “componentized” (the “Loan”), which secures each of the 2018 Securities and the 2023 Securities. The AMT Asset Subs are jointly and severally liable under the Loan, which is secured primarily by mortgages on the AMT Asset Subs’ interests in 5,034 broadcast and wireless communications towers and related assets (the “Trust Sites”). The 2023 Securities correspond to components of the Loan made to the AMT Asset Subs pursuant to the Second Supplement and Amendment dated as of March 13, 2023 (the “2023 Supplement”) to the Second Amended and Restated Loan and Security Agreement dated as of March 29, 2018 (the “Loan Agreement,” which continues to govern the 2018 Securities, and collectively, the “Trust Loan Agreement”). The 2023 Securities (a) represent a pass-through interest in the components of the Loan corresponding to the 2023 Securities and (b) have an expected life of approximately five years with a final repayment date in March 2053. The Series 2023-1A Securities and the Series 2023-1R Securities have interest rates of 5.490% and 5.735%, respectively. Subject to certain limited exceptions described below, no payments of principal will be required to be made on the components of the Loan corresponding to the 2023 Securities prior to the monthly payment date in March 2028, which is the anticipated repayment date for those components. The 2018 Securities (a) represent a pass-through interest in the components of the Loan corresponding to the 2018 Securities and (b) have an expected life of approximately ten years with a final repayment date in March 2048. The Series 2018-1A Securities have an interest rate of 3.652% and the Series 2018-1R Securities have an interest rate of 4.459%. Subject to certain limited exceptions described below, no payments of principal will be required to be made on the components of the Loan corresponding to the 2018 Securities prior to the monthly payment date in March 2028, which is the anticipated repayment date for such components. The AMT Asset Subs are required to make monthly payments of interest on the Loan. The debt service on the Loan will be paid solely from the cash flows generated from the operation of the Trust Sites held by the AMT Asset Subs. The Loan is secured by (1) mortgages, deeds of trust and deeds to secure debt on substantially all of the Trust Sites and their operating cash flows, (2) a security interest in substantially all of the AMT Asset Subs’ personal property and fixtures and (3) the AMT Asset Subs’ rights under that certain management agreement among the AMT Asset Subs and SpectraSite Communications, LLC entered into in March 2013. American Tower Holding Sub, LLC (the “Guarantor”), whose only material assets are its equity interests in each of the AMT Asset Subs, and American Tower Guarantor Sub, LLC whose only material asset is its equity interests in the Guarantor, have each guaranteed repayment of the Loan and pledged their equity interests in their respective subsidiary or subsidiaries as security for such payment obligations. Under the terms of the Loan Agreement and the 2015 Indenture, amounts due will be paid from the cash flows generated by the Trust Sites or the 2015 Secured Sites, respectively, which must be deposited into certain reserve accounts, and thereafter distributed, solely pursuant to the terms of the Loan Agreement or 2015 Indenture, as applicable. On a monthly basis, after payment of all required amounts under the Loan Agreement or 2015 Indenture, as applicable, including interest payments, subject to the conditions described below, the excess cash flows generated from the operation of such assets are released to the AMT Asset Subs or GTP Acquisition Partners, as applicable, which can then be distributed to, and used by, the Company. In order to distribute any excess cash flow to the Company, the AMT Asset Subs and GTP Acquisition Partners must each maintain a specified debt service coverage ratio (the “DSCR”), which is generally calculated as the ratio of the net cash flow (as defined in the applicable agreement) to the amount of interest, servicing fees and trustee fees required to be paid over the succeeding 12 months on the principal amount of the Loan or the 2015 Notes, as applicable, that will be outstanding on the payment date following such date of determination. If the DSCR were equal to or below 1.30x (the “Cash Trap DSCR”) for any quarter, then all cash flow in excess of amounts required to make debt service payments, fund required reserves, pay management fees and budgeted operating expenses and make other payments required under the applicable transaction documents, referred to as excess cash flow, will be deposited into a reserve account (the “Cash Trap Reserve Account”) instead of being released to the AMT Asset Subs or GTP Acquisition Partners, as applicable. The funds in the Cash Trap Reserve Account will not be released to the AMT Asset Subs or GTP Acquisition Partners, as applicable, unless the DSCR exceeds the Cash Trap DSCR for two consecutive calendar quarters. Additionally, if the borrower under the 2023 Securitization does not meet certain title insurance policy requirements within the specified time period under the agreements, excess cash flow will also be deposited into the Cash Trap Reserve Account. Additionally, an “amortization period” commences if, as of the end of any calendar quarter, the DSCR is equal to or below 1.15x (the “Minimum DSCR”) and will continue to exist until the DSCR exceeds the Minimum DSCR for two consecutive calendar quarters. With respect to the Trust Securities, an “amortization period” also commences if, on the anticipated repayment date the component of the Loan corresponding to the applicable subclass of the Trust Securities has not been repaid in full, provided that such amortization period shall apply with respect to such component that has not been repaid in full. If the Series 2015-2 Notes have not been repaid in full on the applicable anticipated repayment date, additional interest will accrue on the unpaid principal balance of the Series 2015-2 Notes, and such notes will begin to amortize on a monthly basis from excess cash flow. During an amortization period, all excess cash flow and any amounts then in the applicable Cash Trap Reserve Account would be applied to pay the principal of the Loan or the Series 2015-2 Notes, as applicable, on each monthly payment date. The Loan and the Series 2015-2 Notes may be prepaid in whole or in part at any time, provided such payment is accompanied by the applicable prepayment consideration. If the prepayment occurs within (i) 18 months of the anticipated repayment date with respect to the Series 2015-2 Notes, (ii) 36 months of the anticipated repayment date with respect to the Series 2018 Securities, and (iii) 12 months of the anticipated repayment date for the 2023 Securities, no prepayment consideration is due. The Loan Agreement and the 2015 Indenture include operating covenants and other restrictions customary for transactions subject to rated securitizations. Among other things, the AMT Asset Subs and the GTP Entities, as applicable, are prohibited from incurring other indebtedness for borrowed money or further encumbering their assets subject to customary carve-outs for ordinary course trade payables and permitted encumbrances (as defined in the Loan Agreement or the 2015 Indenture, as applicabl |

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, 2023 December 31, 2022 Fair Value Measurements Using Fair Value Measurements Using Level 1 Level 2 Level 3 Level 1 Level 2 Level 3 Assets: Investments in equity securities (1) $ 28.2 $ 5.3 — $ 29.2 — — VIL OCDs — $ 192.3 — — — — Liabilities: Interest rate swap agreements — — — — $ 6.2 — Fair value of debt related to interest rate swap agreements (2) — — — $ (4.9) — — _______________ (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 years ended December 31, 2023 and 2022 , the Company recognized unrealized gains (losses) of $4.3 million and $(16.7) million, respectively, for equity securities held as of December 31, 2023. (2) Included in the carrying values of the corresponding debt obligations as of December 31, 2022. As of December 31, 2023, the interest rate swap agreements under the 3.000% Notes were settled. 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% 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 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 3.000% through June 15, 2023. The interest rate swap agreements expired upon repayment of the 3.000% Notes in full on June 15, 2023 upon maturity. As of December 31, 2023, there were no amounts outstanding under the interest rate swap agreements under the 3.000% Notes. During the year ended December 31, 2023, there were no material fair value adjustments related to interest rate swaps. VIL Optionally Convertible Debentures —In February 2023, one of the Company’s customers in India, Vodafone Idea Limited (“VIL”), issued optionally convertible debentures (the “VIL OCDs”) to the Company’s subsidiary, ATC Telecom Infrastructure Private Limited (“ATC TIPL”), in exchange for VIL’s payment of certain amounts towards accounts receivables. The VIL OCDs are (a) to be repaid by VIL with interest or (b) convertible into equity of VIL. If converted, such equity shall be free to trade in the open market beginning on the one year anniversary of the date of issuance of the VIL OCDs. The VIL OCDs were issued for an aggregate face value of 16.0 billion INR (approximately $193.2 million on the date of issuance). The VIL OCDs were to mature in tranches with 8.0 billion INR (approximately $96.6 million on the date of issuance) maturing on August 27, 2023 and 8.0 billion INR (approximately $96.6 million on the date of issuance) maturing on August 27, 2024. In August 2023, the Company amended the agreements governing the VIL OCDs to, among other items, extend the maturity of the first tranche of the VIL OCDs to August 27, 2024. The fair value of the VIL OCDs at issuance was approximately $116.5 million. The VIL OCDs accrue interest at a rate of 11.2% annually. Interest is payable to ATC TIPL semi-annually, with the first payment received in September 2023. The VIL OCDs are recorded in Prepaid and other current assets in the consolidated balance sheet at fair value. The significant input to the fair value of the VIL OCDs is the lesser of the (i) VIL equity share price underlying the instruments, less a liquidity discount, and (ii) redemption value. Unrealized holding gains and losses for the VIL OCDs are recorded in Other income (expense) in the consolidated statements of operations in the current period. During the year ended December 31, 2023, the Company recognized unrealized gains of $76.7 million for the VIL OCDs held as of December 31, 2023. 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, 2023, long-lived assets held and used with a carrying value of $35.2 billion, included assets of approximately $0.2 billion that were written down to their net realizable value of less than $0.1 billion as a result of an asset impairment charge of $202.4 million. During the year ended December 31, 2022, long-lived assets held and used with a carrying value of $46.1 billion, included assets of approximately $0.8 billion that were written down to their net realizable value of approximately $0.2 billion as a result of an asset impairment charge of $655.9 million. The asset impairment charges are recorded in Other operating expenses in the accompanying consolidated statements of operations The significant unobservable inputs used to determine the fair value of the individual tower and acquired network location intangible assets subject to impairment in 2023 and 2022 included the following: Year Ended December 31, 2023 2022 Range Weighted Average Range Weighted Average Terminal growth rates on cash flows (1) 2% to 7% 3% 3% to 7% 3% Weighted average cost of capital (2) 6% to 46% 10% 6% to 35% 13% _______________ (1) On a local currency basis. (2) Specific to the country of each impaired asset. Due to the underlying economic characteristics of the markets the Company operates in, the weighted average cost of capital may vary significantly from market to market. The majority of the tenant relationships measured at fair value for impairment purposes in 2022 utilized a weighted average cost of capital of 11%; however, terminal growth rates are not used in the valuation of acquired tenant-related intangible assets. The table below indicates the percentages of the asset class that were subject to fair value measurement and subsequently impaired for the years ended December 31, 2023 and 2022: 2023 2022 Towers and related assets 1% 1% Acquired network location intangible assets 1% 2% Acquired tenant-related intangible assets 1% 5% The Company believes any reasonable change in the significant unobservable inputs utilized would not have a material impact on the fair value of the assets used in connection with the impairment recorded. During the year ended December 31, 2023, the Company undertook a process to evaluate various strategic alternatives with respect to its India operations, which resulted in the Pending ATC TIPL Transaction (as defined in note 22) in January 2024. As part of this process, the Company received indications of value from third parties, which were less than the carrying value of the India reporting unit. The Company incorporated this information as a significant input used to determine the fair value of the India reporting unit. The Company performed its annual goodwill impairment test as of December 31, 2023. The Company determined that the carrying amount of the Spain reporting unit exceeded its fair value, as calculated under an income approach using future discounted cash flows. The significant unobservable inputs used to determine the fair value of the Spain reporting until as of December 31, 2023 included the following: 2023 Terminal growth rates on cash flows 2% Weighted average cost of capital 7% During the year ended December 31, 2023, the Company recorded goodwill impairments of $322.0 million related to India and $80.0 million related to Spain, for a total of $402.0 million, as discussed further in note 5. There were no other items measured at fair value on a nonrecurring basis during the year ended December 31, 2023. Fair Value of Financial Instruments —The Company’s financial instruments for which the carrying value reasonably approximates fair value at December 31, 2023 and 2022 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, 2023, the carrying value and fair value of long-term obligations, including the current portion, were $38.9 billion and $36.7 billion, respectively, of which $30.0 billion was measured using Level 1 inputs and $6.7 billion was measured using Level 2 inputs. As of December 31, 2022, the carrying value and fair value of long-term obligations, including the current portion, were $38.7 billion and $35.1 billion, respectively, of which $24.5 billion was measured using Level 1 inputs and $10.6 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, 2023 2022 2021 Current: Federal $ (1.0) $ (6.5) $ (26.0) State (4.9) (5.8) (9.3) Foreign (330.3) (248.4) (267.7) Deferred: Federal 1.8 (2.8) 0.0 State 0.8 0.8 (2.5) Foreign 179.4 238.7 43.7 Income tax provision $ (154.2) $ (24.0) $ (261.8) The effective tax rate (“ETR”) on income from continuing operations for the years ended December 31, 2023, 2022 and 2021 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. For the year ended December 31, 2023, the increase in the income tax provision was primarily attributable to increased earnings in certain foreign jurisdictions in the current year after adjusting for non-deductible amounts, partially offset by a benefit in the current year from the application of a tax law change in Kenya. The income tax provision for the year ended December 31, 2022 included a reduction in income due to intangible asset impairment charges in India. The income tax provision for the year ended December 31, 2023 included the reversal of valuation allowances of $87.2 million in certain foreign jurisdictions as compared to the reversal of valuation allowances of $76.5 million for the year ended December 31, 2022. Reconciliation between the U.S. statutory rate and the effective rate from continuing operations is as follows: Year Ended December 31, 2023 2022 2021 Statutory tax rate 21 % 21 % 21 % Adjustment to reflect REIT status (1) (21) (21) (21) Foreign taxes 9 (1) 3 Foreign withholding taxes 4 4 2 Uncertain tax positions 4 2 4 Changes in tax laws (2) — — Changes in valuation allowance (5) (4) (0) Effective tax rate 10 % 1 % 9 % _______________ (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, 2023 2022 2021 United States $ 1,371.4 $ 1,973.2 $ 2,517.4 Foreign 149.9 (252.5) 312.0 Total $ 1,521.3 $ 1,720.7 $ 2,829.4 The components of the net deferred tax asset and liability and related valuation allowance were as follows: December 31, 2023 December 31, 2022 Assets: Operating lease liability $ 1,147.3 $ 1,117.4 Net operating loss carryforwards 276.4 265.5 Accrued asset retirement obligations 245.9 238.5 Stock-based compensation 8.5 8.1 Unearned revenue 35.8 32.7 Unrealized loss on foreign currency 20.8 24.4 Other accruals and allowances 89.1 84.1 Nondeductible interest 67.1 93.4 Tax credits 158.8 106.8 Capital loss carryforwards (1) 175.0 5.8 Items not currently deductible and other 84.5 44.3 Liabilities: Depreciation and amortization (1,718.1) (1,792.6) Right-of-use asset (1,147.2) (1,118.5) Deferred rent (133.9) (113.0) Other (58.8) (24.0) Subtotal (748.8) (1,027.1) Valuation allowance (433.5) (335.7) Net deferred tax liabilities $ (1,182.3) $ (1,362.8) _______________ (1) As of December 31, 2023 includes amounts related to the sale of Mexico Fiber. 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, 2023 and 2022, the Company has provided a valuation allowance of $433.5 million and $335.7 million, respectively, which primarily relates to foreign items. The increase in the valuation allowance for the year ending December 31, 2023 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: 2023 2022 2021 Balance as of January 1, $ 335.7 $ 329.3 $ 228.5 Additions (1) 249.1 93.9 146.3 Usage, expiration and reversals (87.2) (76.5) (26.2) Foreign currency translation (64.1) (11.0) (19.3) Balance as of December 31, $ 433.5 $ 335.7 $ 329.3 _______________ (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. The Company intends to reinvest foreign earnings indefinitely outside of the U.S., except for earnings in certain entities in Brazil, Burkina Faso, Costa Rica, Jersey, Mexico, Netherlands, Singapore, South Africa and the United Kingdom. Any tax consequences for future distributions have been recorded as deferred tax liabilities. At December 31, 2023, 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 2024 to 2028 $ 0.0 $ 217.1 $ 3.7 2029 to 2033 0.7 47.1 4.0 2034 to 2038 66.9 150.9 1.1 2039 to 2043 — 97.2 9.3 Indefinite carryforward 283.0 60.4 928.7 Total $ 350.6 $ 572.7 $ 946.8 As of December 31, 2023 and 2022, the total amount of unrecognized tax benefits that would impact the ETR, if recognized, is $130.7 million and $103.6 million, respectively. The amount of unrecognized tax benefits for the year ended December 31, 2023 includes additions to the Company’s existing tax positions of $50.5 million. The Company expects the unrecognized tax benefits to change over the next 12 months if certain tax matters ultimately settle with the applicable taxing jurisdiction during this timeframe, 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 $13.9 million. A reconciliation of the beginning and ending amount of unrecognized tax benefits are as follows: Year Ended December 31, 2023 2022 2021 Balance at January 1 $ 115.5 $ 108.8 $ 136.2 Additions based on tax positions related to the current year 42.5 13.3 7.5 Additions and reductions for tax positions of prior years (1) 0.4 18.2 (17.5) Foreign currency 3.7 (5.3) (3.7) Reduction as a result of the lapse of statute of limitations (2.1) (0.6) (4.9) Reduction as a result of effective settlements (5.9) (18.9) (8.8) Balance at December 31 $ 154.1 $ 115.5 $ 108.8 _______________ (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. During the year ended December 31, 2023, 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 $15.5 million in the liability for unrecognized tax benefits. During the year ended December 31, 2022, 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 $23.1 million in the liability for unrecognized tax benefits. 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 related to the Eaton Towers Acquisition, which resulted in a decrease in the liability for unrecognized tax benefits of $54.2 million. The Company recorded penalties and tax-related interest expense to the tax provision of $26.2 million, $20.6 million and $69.5 million for the years ended December 31, 2023, 2022 and 2021, respectively. During the year ended December 31, 2023, the Company reduced its liability for penalties and income tax-related interest expense related to uncertain tax positions by $9.7 million due to the expiration of the statute of limitations in certain jurisdictions and certain positions that were effectively settled. During the years ended December 31, 2022 and 2021, the Company reduced its liability for penalties and income tax-related interest expense related to uncertain tax positions by $19.9 million and $14.6 million, respectively, 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 was reclassified to Accrued income tax payable as of December 31, 2021. As of December 31, 2023 and 2022, the total amount of accrued income tax-related interest and penalties included in the consolidated balance sheets were $62.8 million and $43.3 million, respectively. The Company has filed for prior taxable years, and for its taxable year ended December 31, 2023 will file, numerous consolidated and separate income tax returns, including U.S. federal and state tax returns and foreign tax returns. The Company is subject to examination in the United States and various state and foreign jurisdictions for certain tax years. As a result of the Company’s ability to carryforward federal, state and foreign NOLs, the applicable tax years generally remain open to examination several years after the applicable loss carryforwards have been used or have expired. The Company regularly assesses the likelihood of additional assessments in each of the tax jurisdictions resulting from these examinations. The Company believes that adequate provisions have been made for income taxes for all periods through December 31, 2023. |

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. Awards of RSUs and stock options granted prior to March 10, 2023 generally vest over four years. In December 2022, the Company’s Compensation Committee changed the terms of its awards to generally vest over three years. The change in vesting terms is applicable for new awards granted beginning on March 10, 2023 and does not change the vesting terms applicable to grants awarded prior to March 10, 2023. The impact of the change in vesting terms was $7.9 million for the year ended December 31, 2023. Performance-based restricted stock units (“PSUs”) generally vest over three years. Stock options generally expire ten years from the date of grant. As of December 31, 2023, the Company had the ability to grant stock-based awards with respect to an aggregate of 4.1 million shares of common stock under the 2007 Plan. 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, 2023, 2022 and 2021, the Company recorded the following stock-based compensation expenses in selling, general, administrative and development expense: 2023 2022 2021 Stock-based compensation expense (1) $ 195.7 $ 169.3 $ 119.5 _______________ (1) For the year ended December 31, 2023, excludes $7.6 million of stock-based compensation expenses related to severance recorded in Other operating expense in the accompanying consolidated statements of operations. Stock Options —There were no options granted during the years ended December 31, 2023, 2022 and 2021. 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, 2023, 2022 and 2021 was $9.3 million, $34.3 million and $176.7 million, respectively. As of December 31, 2023, there was no unrecognized compensation expense related to unvested stock options. The amount of cash received from the exercise of stock options was $7.7 million during the year ended December 31, 2023.

(2) PSUs consist of the target number of shares issuable at the end of the three-year performance period for the 2023 PSUs (as defined below), or 118,684 shares, and target number of shares issuable at the end of the one-year performance period for the Retention PSUs (as defined below), or 19,132 shares. PSUs also includes the shares above target that are issuable for the 2021 PSUs at the end of the three-year performance cycle based on exceeding the performance metric for the three-year performance period, or 28,624 shares. (3) PSUs consist of shares vested pursuant to the 2020 PSUs. There are no additional shares to be earned related to the 2020 PSUs. (4) Vested and deferred RSUs are related to deferred compensation for certain former employees. The total fair value of RSUs and PSUs that vested during the year ended December 31, 2023 was $137.2 million. Restricted Stock Units— As of December 31, 2023, total unrecognized compensation expense related to unvested RSUs granted under the 2007 Plan was $172.4 million and is expected to be recognized over a weighted average period of approximately two years. Vesting of RSUs is subject generally to the employee’s continued employment or death, disability or qualified retirement (each as defined in the applicable RSU award agreement). Performance-Based Restricted Stock Units— During the year ended December 31, 2023, the Company’s Compensation Committee (the “Compensation Committee”) granted an aggregate of 118,684 PSUs (the “2023 PSUs”) to its executive officers and established the performance metrics for these awards. During the years ended December 31, 2022 and 2021, the Company’s Compensation Committee granted an aggregate of 98,542 PSUs (the “2022 PSUs”), 98,694 PSUs (the “2021 PSUs”), respectively, to its executive officers and established the performance metrics for these awards. Threshold, target and maximum parameters were established for the metrics for a three-year performance period with respect to each of the 2023 PSUs, the 2022 PSUs and the 2021 PSUs and will be used to calculate the number of shares that will be issuable when each award vests, which may range from zero to 200% of the target amounts. At the end of each three-year performance period, the number of shares that vest will depend on the degree of achievement against the pre-established performance goals. PSUs will be paid out in common stock at the end of each performance period, subject generally to the executive’s continued employment or death, disability or qualified retirement (each as defined in the applicable PSU award agreement). PSUs will accrue dividend equivalents prior to vesting, which will be paid out only in respect of shares that actually vest. During the year ended December 31, 2023, the Company’s Compensation Committee granted an aggregate of 19,132 PSUs to certain non-executive employees (the “Retention PSUs”) and established the performance metrics for these awards. Target parameters were established for a one-year performance period and will be used to calculate the number of shares that will be issuable when the awards vest, which may be either zero or 100% of the target amount. At the end of the one-year performance period, the number of shares that vest will depend on the achievement against the pre-established performance goals. The Retention PSUs will be paid out in common stock at the end of performance period, subject generally to the employee’s continued employment, death or disability (each as defined in the applicable award agreement). The Retention PSUs will accrue dividend equivalents prior to vesting, which will be paid out only in respect of shares that actually vest. The Company recognized $3.5 million in stock-based compensation expense related to the Retention PSUs. As of December 31, 2023, there was no unrecognized compensation expense related to the Retention PSUs. |

Equity [Abstract] | |
EQUITY | EQUITY Dividends —The Company may pay dividends in cash or, subject to certain limitations, in shares of common stock or any combination of cash and shares of common stock. Sales of Equity Securities —The Company receives proceeds from sales of its equity securities pursuant to the ESPP and upon exercise of stock options granted under the 2007 Plan. During the year ended December 31, 2023, the Company received an aggregate of $22.1 million in proceeds upon exercises of stock options and sales pursuant to the ESPP. Stock Repurchase Programs —In March 2011, the Company’s Board of Directors approved a stock repurchase program, pursuant to which the Company is authorized to repurchase up to $1.5 billion of its common stock (the “2011 Buyback”). In December 2017, the Board of Directors approved an additional stock repurchase program, pursuant to which the Company is authorized to repurchase up to $2.0 billion of its common stock (the “2017 Buyback,” and, together with the 2011 Buyback, the “Buyback Programs”). During the year ended December 31, 2023, there were no repurchases under either of the Buyback Programs. As of December 31, 2023, the Company has repurchased a total of 14,451,325 shares of its common stock under the 2011 Buyback for an aggregate of $1.5 billion, including commissions and fees. As of December 31, 2023, the Company has not made any repurchases under the 2017 Buyback. Under the Buyback Programs, the Company is authorized to purchase shares from time to time through open market purchases or in privately negotiated transactions not to exceed market prices and subject to market conditions and other factors. With respect to open market purchases, the Company may use plans adopted in accordance with Rule 10b5-1 under the Exchange Act in accordance with securities laws and other legal requirements, which allows the Company to repurchase shares during periods when it may otherwise be prevented from doing so under insider trading laws or because of self-imposed trading blackout periods. The Company expects to fund any further repurchases of its common stock through a combination of cash on hand, cash generated by operations and borrowings under its credit facilities. Repurchases under the Buyback Programs are subject to, among other things, the Company having available cash to fund the repurchases. Distributions —During the years ended December 31, 2023, 2022 and 2021, the Company declared the following cash distributions (per share data reflects actual amounts): For the year ended December 31, 2023 2022 2021 Distribution Aggregate Distribution Aggregate Distribution Aggregate Common Stock $ 6.45 $ 3,006.7 $ 5.86 $ 2,715.3 $ 5.21 $ 2,359.4 The following table characterizes the tax treatment of distributions declared per share of common stock.

NONCONTROLLING INTERESTS | NONCONTROLLING INTERESTS European Interests— In 2021 , PGGM converted its previously held noncontrolling interest in a subsidiary that primarily consisted of the Company’s operations in France, Germany and Poland (“Former ATC Europe”) into noncontrolling interests in subsidiaries, consisting of the Company's operations in Germany and Spain. In 2021, Caisse de dépôt et placement du Québec (“CDPQ”) and Allianz insurance companies and funds managed by Allianz Capital Partners GmbH, including the Allianz European Infrastructure Fund (collectively, “Allianz”) acquired 30% and 18% noncontrolling interests, respectively, in ATC Europe (the “ATC Europe Transactions”) for total aggregate consideration of 2.6 billion EUR (approximately $3.1 billion at the date of closing). As of December 31, 2023, ATC Europe consists of the Company’s operations in France, Germany and Spain. The Company currently holds a 52% controlling interest in ATC Europe, with CDPQ and Allianz holding 30% and 18% noncontrolling interests, respectively. ATC Europe holds a 100% interest in the subsidiaries that consist of the Company’s operations in France and an 87% and an 83% controlling interest in the subsidiaries that consist of the Company’s operations in Germany and Spain, respectively, with PGGM holding a 13% and a 17% noncontrolling interest in each respective subsidiary. Bangladesh Partnership —In August 2021, the Company acquired a 51% controlling interest in in Kirtonkhola Tower Bangladesh Limited (“KTBL”) for 900 million BDT (approximately $10.6 million at the date of closing). Confidence Group holds a 49% noncontrolling interest in KTBL. Stonepeak Transaction —In July 2022, the Company entered into an agreement pursuant to which certain investment vehicles affiliated with Stonepeak Partners LP (such investment vehicles, collectively, “Stonepeak”) acquired a noncontrolling ownership interest in the Company’s U.S. data center business. The transaction was completed in August 2022 for total aggregate consideration of $2.5 billion, through an investment in common equity of $1,750.0 million and mandatorily convertible preferred equity of $750.0 million. In October 2022, the Company entered into an agreement with Stonepeak for Stonepeak to acquire additional common equity and mandatorily preferred equity interests in the Company’s U.S. data center business for total aggregate consideration of $570.0 million (together with the August 2022 closing, the “Stonepeak Transaction”).

Other Income and Expenses [Abstract] | |
OTHER OPERATING EXPENSE | OTHER OPERATING EXPENSE Other operating expense consists primarily of impairment charges, net losses on sales or disposals of assets and other operating expense items. The Company records impairment charges to write down certain assets to their net realizable value after an indicator of impairment is identified and subsequent analysis determines that the asset is either partially recoverable or not recoverable. These assets consist primarily of those related to the Company’s tower locations, and included towers and related assets included in property and equipment, network location intangible assets and right-of-use assets, all of which are typically assessed on an individual location or site basis. The assets subject to impairment also include tenant-related intangibles, which are assessed on a tenant basis. Net losses on sales or disposals of assets primarily relate to certain non-core towers, other assets and miscellaneous items. Other operating expenses includes acquisition- and disposition-related costs and integration costs. Other operating expenses included the following for the years ended December 31,: 2023 2022 2021 Impairment charges (1) $ 202.4 $ 655.9 $ 173.7 Net losses on sales or disposals of assets (2) 125.4 28.4 22.7 Other operating expenses (3) 49.9 83.3 202.3 Total Other operating expenses $ 377.7 $ 767.6 $ 398.7 _______________ (1) For the year ended December 31, 2022, impairment charges primarily relate to India, as discussed below.

(4) During the year ended December 31, 2023, includes goodwill impairment associated with the India and Spain reporting units (as discussed in note 5). India Impairments The Company reviews long-lived assets for impairment annually (as of December 31) or whenever events or circumstances indicate the carrying amount of an assets may not be recoverable, as further discussed in note 1. In the third quarter of 2022, VIL, communicated that it would make partial payments of its contractual amounts owed to the Company and indicated that it would continue to make partial payments for the remainder of 2022. In late 2022, VIL had communicated its intent to resume payments in full under its contractual obligations owed to the Company beginning on January 1, 2023. However, in early 2023, VIL communicated that it would not be able to resume payments in full of its contractual obligations owed to the Company, and that it would instead continue to make partial payments. In the second half of 2023, VIL began making payments in full of its monthly contractual obligations owed to the Company. The Company considered these developments and the uncertainty with respect to amounts owed under its tenant leases when conducting its 2022 annual impairment assessments for long-lived assets in India. A probability weighted assessment was performed, incorporating current and expected industry and market conditions and trends and, as a result, the Company determined that certain fixed and intangible assets had been impaired during the year ended December 31, 2022. • An impairment of $97.0 million was taken on tower and network location intangible assets in India. • The Company also impaired the tenant-related intangible assets for VIL, which resulted in an impairment of $411.6 million. The Company recorded a goodwill impairment charge of $322.0 million in India during the year ended December 31, 2023 as discussed in note 5. The goodwill impairment charge is recorded in Goodwill impairment in the accompanying consolidated statements of operations for the year ended December 31, 2023. Severance During the year ended December 31, 2023, the Company approved a plan for restructuring its workforce, which was communicated to its employees.

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 11,200 wireless communications sites, which commenced on March 27, 2015. The average term of the lease or sublease for all communications 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 1,800 towers, which commenced 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, 2023, the Company has purchased an aggregate of approximately 600 of the subleased towers which are subject to the applicable agreement, including 59 towers purchased during the year ended December 31, 2023 for an aggregate purchase price of $40.9 million. The aggregate purchase option price for the remaining towers leased and subleased is $1.1 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. 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, 2023, is not aware of any agreements that could result in a material payment. |

Segment Reporting [Abstract] | |
BUSINESS SEGMENTS | BUSINESS SEGMENTS Property 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. The Company has historically reported these operations on a geographic basis. Data Centers — In December 2021, the Company completed the CoreSite Acquisition, through which it acquired over 20 data center facilities and related assets in eight United States markets. As a result of the CoreSite Acquisition, the Company established the Data Centers segment as a reportable segment in the fourth quarter of 2021. The Company’s 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 types of leased land and related services from, and requires different resources, skill sets and marketing strategies than the existing property operating segment in the U.S. & Canada. As of December 31, 2023, 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, New Zealand and the Philippines; • Africa: property operations in Burkina Faso, Ghana, Kenya, Niger, Nigeria, South Africa and Uganda; • Europe: property operations in France, Germany 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, structural and mount analyses, and construction management, which primarily support its site leasing business, including the addition of new tenants and equipment on its communications 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 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, 2023, 2022 and 2021 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.

BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies) | 12 Months Ended |

Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Business | 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, inclusive of its data center business discussed below, 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”), structural and mount analyses and construction management, 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 provides for the leasing of space 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 offsets its REIT taxable 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. |
Principles of Consolidation and Basis of Presentation | Principles of Consolidation and Basis of Presentation |
Reportable Segments | Reportable Segments —The Company reports 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 20. |
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 45% 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 for 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 (“AOCL”) in the consolidated balance sheets and included as a component of Comprehensive income in the consolidated statements of comprehensive income. |
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, 2023, 2022 and 2021 were $64.4 million, $65.2 million and $59.4 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 estimated useful life of the asset taking into consideration the term of the corresponding ground lease 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 16, in Other operating expenses in the consolidated statements of operations in the period in which the Company identifies such impairment. The Company is in the process of finalizing its review of the estimated useful lives of its tower assets. The Company now has over 20 years of operating history, and it is considering whether it should modify its current estimates for asset lives based on its historical operating experience. The Company has retained an independent consultant to assist the Company in completing this review and analysis. The Company currently depreciates its towers on a straight-line basis over the shorter of the term of the underlying ground lease (including renewal options) taking into account residual value or the estimated useful life of the tower, which the Company has historically estimated to be 20 years. Additionally, certain of the Company’s intangible assets are amortized on a similar basis to its tower assets, as the estimated useful lives of such intangible assets correlate to the useful life of the towers. If the Company concludes that a revision in the estimated useful lives of its tower assets is appropriate based on its review and analysis, which the Company expects to conclude in 2024, the Company will account for any changes in the useful lives as a change in accounting estimate under ASC 250 Accounting Changes and Error Corrections, which will be recorded prospectively beginning in the period of change. Based on preliminary information obtained to date, the Company expects that its estimated asset lives may be extended, which would result in an estimated (i) $700 million to $800 million decrease in depreciation and amortization for the year ended December 31, 2024 and (ii) $450 million to $550 million increase in the right of use asset, as additional renewal options may be included, with an offsetting adjustment made to increase the related operating lease liability. |
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 revenue 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 year ended December 31, 2023, the Company concluded that a triggering event occurred with respect to its India reporting unit. As a result, the Company performed a goodwill impairment test based on information observed during its review of strategic alternatives for this reporting unit. The result of the Company’s goodwill impairment test indicated that the carrying amount of the Company's India reporting unit exceeded its estimated fair value. As a result, the Company recorded a goodwill impairment charge of $322.0 million during the quarter ended September 30, 2023. The Company also performed its annual goodwill impairment test as of December 31, 2023. The results of the annual goodwill impairment test indicated that the carrying amount of the Company’s Spain reporting unit exceeded its estimated fair value. As a result, the Company recorded a goodwill impairment charge of $80.0 million. The goodwill impairment charges are recorded in Goodwill impairment in the accompanying consolidated statements of operations. During the years ended December 31, 2023, 2022 and 2021, no other goodwill 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 two 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, the customer’s ability to meet its contractual obligations, 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 16, in Other operating expenses in the consolidated statements of operations in the period in which the Company identifies such impairment. |
Fair Value Measurements | Fair Value Measurements |
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. 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. The Company is in the process of finalizing its review of the estimated settlement dates for its asset retirement obligations. The Company now has over 20 years of operating history, and it is considering whether it should modify its current estimated settlement dates based on its historical operating experience, management’s intent with respect to the assets, and the assets’ estimated useful lives. The Company expects to complete its review of estimated settlement dates in the first quarter of 2024. If the Company concludes that a revision in the estimated settlement dates for its asset retirement obligations is appropriate based on its review and analysis, the Company will account for any changes in the estimated settlement dates as a change in accounting estimate under ASC 250 Accounting Changes and Error Corrections, which will be recorded prospectively beginning in the period of change. Based on preliminary information obtained to date, the Company expects that its estimated settlement dates may be extended. The extension in the estimated settlement dates would result in an estimated (i) $400 million to $500 million increase in the asset retirement obligation liability, with an offsetting adjustment made to the related long-lived tangible asset, (ii) $800 million to $900 million increase in the estimated undiscounted future cash outlay for asset retirement obligations, and (iii) $50 million to $100 million decrease in estimated accretion expense for the year ended December 31, 2024. |
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) |
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. |
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, land underlying our customers’ sites and the space in 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 customers that 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, 2023, 2022 and 2021 were $472.0 million, $499.8 million and $465.6 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 offerings in the Company’s data center facilities. Interconnection offerings 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, structural and mount analyses, and construction management. There is a single performance obligation related to AZP and construction management, and revenue is recognized over time based on milestones achieved, which are determined based on costs expected to be incurred. Structural and mount analyses 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, 2023, the Company recognized $143.6 million of revenue that was previously included in the contract liabilities balances, primarily arising from balances as of December 31, 2022. 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, 2023 and 2022. The change in contract assets attributable to revenue recognized during the years ended December 31, 2023 and 2022 was $0.6 million and $(0.3) 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 also 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 16, 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 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. Equity awards typically vest ratably. Awards of RSUs and stock options granted prior to March 10, 2023 generally vest over four years. In December 2022, the Company’s Compensation Committee changed the terms of its awards to generally vest over three years. The change in vesting terms is applicable for new awards granted beginning on March 10, 2023 and does not change the vesting terms applicable to grants awarded prior to March 10, 2023. 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 Selling, general, administrative and development expense. |
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. |

Accounting Standards Updates | Accounting Standards Updates —In November 2023, the Financial Accounting Standards Board (“FASB”) issued guidance which is intended to improve reportable segment disclosure requirements, primarily through additional disclosures about significant segment expenses. The standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The amendments should be applied retrospectively to all prior periods presented in the financial statements. The Company is currently evaluating the impact of this guidance on its consolidated financial statements and related disclosures. In December 2023, the FASB issued guidance which requires public entities to provide enhanced income tax disclosures on an annual basis. The new guidance requires an expanded rate reconciliation and the disaggregation of cash taxes paid by U.S. federal, U.S. state and foreign jurisdictions. The updated guidance is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the impact of this guidance on its consolidated financial statements and related disclosures. |
