AMERICAN TOWER CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED AND CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(tabular amounts in millions, unless otherwise noted)

1.    BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES
The accompanying consolidated and condensed consolidated financial statements have been prepared by American Tower Corporation (together with its subsidiaries, “ATC” or the “Company”) pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). The financial information included herein is unaudited. However, the Company believes that all adjustments, which are of a normal and recurring nature, considered necessary for a fair presentation of its financial position and results of operations for such periods have been included herein. The consolidated and condensed consolidated financial statements and related notes should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2021 (the “2021 Form 10-K”). The results of operations for the three months ended March 31, 2022 are not necessarily indicative of the results that may be expected for the entire year.
Principles of Consolidation and Basis of Presentation—The accompanying consolidated and condensed consolidated financial statements include the accounts of the Company and those entities in which it has a controlling interest. Investments in entities that the Company does not control are accounted for using the equity 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 March 31, 2022, the Company holds (i) a 52% controlling interest in subsidiaries whose holdings consist of the Company’s operations in France, Germany, Poland and Spain (such subsidiaries collectively, “ATC Europe”) (Allianz and CDPQ (each as defined in note 11) hold the noncontrolling interests) and (ii) a 51% controlling interest in a joint venture whose holdings consist of the Company’s operations in Bangladesh (Confidence Tower Holdings Ltd. (“Confidence Group”) holds the noncontrolling interest). As of March 31, 2022, 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 11 for a discussion of changes to the Company’s noncontrolling interests during the three months ended March 31, 2022 and 2021.
Change in Reportable Segments—During the fourth quarter of 2021, as a result of the Company’s acquisition of CoreSite Realty Corporation (“CoreSite,” and the acquisition, the “CoreSite Acquisition”), the Company updated its reportable segments to add a Data Centers segment. The Data Centers segment is within the Company’s property operations. The Company now reports its results in seven segments – U.S. & Canada property, Asia-Pacific property, Africa property, Europe property, Latin America property, Data Centers and Services, which are discussed further in note 15. The change in reportable segments had no impact on the Company’s consolidated financial statements for any prior periods. Historical financial information included in this Quarterly Report on Form 10-Q (this “Quarterly Report”) has been adjusted to reflect the change in reportable segments.
Significant Accounting Policies—The Company’s significant accounting policies are described in note 1 to the Company’s consolidated financial statements included in the 2021 Form 10-K. There have been no material changes to the Company’s significant accounting policies during the three months ended March 31, 2022.
Cash and Cash Equivalents and Restricted CashThe 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:
Three Months Ended March 31,
20222021
Cash and cash equivalents$1,941.5 $1,913.6 
Restricted cash329.9 79.7 
Total cash, cash equivalents and restricted cash$2,271.4 $1,993.3 
The increase in restricted cash during the three months ended March 31, 2022 was due to advance payments from a customer received during the year ended December 31, 2021.
Revenue—The Company’s revenue is derived from leasing the right to use its communications sites, the land on which the sites are located and its data center facilities (the “lease component”) and from the reimbursement of costs incurred by the Company in operating the communications sites and data center facilities and supporting its customers’ equipment as well as other services and contractual rights (the “non-lease component”). Most of the Company’s revenue is derived from leasing arrangements and is accounted for as lease revenue unless the timing and pattern of revenue recognition of
6

AMERICAN TOWER CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED AND CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(tabular amounts in millions, unless otherwise noted)
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 distributed antenna system (“DAS”) networks and fiber and other related assets results from agreements with customers are generally not accounted for as leases.
Non-lease property revenue—Non-lease property revenue consists primarily of revenue generated from DAS networks, fiber and other property related revenue. DAS networks and fiber arrangements generally require that the Company provide the tenant the right to use available capacity on the applicable communications infrastructure. Performance obligations are satisfied over time for the duration of the arrangements. Non-lease property revenue also includes revenue generated from interconnection services in the Company’s data center facilities. Interconnection services are generally contracted on a month-to-month basis and are cancellable by the Company or the data center customer at any time. Performance obligations are satisfied over time for the duration of the arrangements. Other property related revenue streams, which include site inspections, are not material on either an individual or consolidated basis. There were no material changes in the receivables, contract assets and contract liabilities from contracts with customers for the three months ended March 31, 2022.
Services revenue—The Company offers tower-related services in the United States. These services include site application, zoning and permitting (“AZP”) and structural analysis. There is a single performance obligation related to AZP and revenue is recognized over time based on milestones achieved, which are determined based on costs expected to be incurred. Structural analysis services may have more than one performance obligation, contingent upon the number of contracted services. Revenue is recognized at the point in time the services are completed.
A summary of revenue disaggregated by source and geography is as follows:

Accounting Standards Updates
In March 2020, the Financial Accounting Standards Board (the “FASB”) issued guidance to provide optional expedients and exceptions for applying accounting principles generally accepted in the United States to contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. The guidance applies only to contracts, hedging relationships and other transactions that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the guidance do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022 for which an
7

entity has elected certain optional expedients that are retained through the end of the hedging relationship. In January 2021, the FASB issued additional guidance that clarifies that certain practical expedients and exceptions for contract modifications and hedge accounting apply to derivatives that are affected by reference rate reform. As of March 31, 2022, the Company has not modified any contracts as a result of reference rate reform and is evaluating the impact this standard may have on its financial statements.
2.    PREPAID AND OTHER CURRENT ASSETS

3.    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.
During the three months ended March 31, 2022, the Company made no changes to the methods described in note 4 to its consolidated financial statements included in the 2021 Form 10-K. As of March 31, 2022, the Company does not have any material related party leases as either a lessor or a lessee. To the extent there are any intercompany leases, these are eliminated in consolidation.

Lessor— 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 land underneath its sites when calculating future minimum rental receipts. Future minimum rental receipts expected under non-cancellable operating lease agreements as of March 31, 2022 were as follows:
Fiscal Year Amount (1)
Remainder of 2022$5,030.8

Lessee—The Company assesses its right-of-use asset and other lease-related assets for impairment, as described in note 1 to the Company’s consolidated financial statements included in the 2021 Form 10-K. There were no material impairments recorded related to these assets during the three months ended March 31, 2022 and 2021.
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 March 31, 2022, operating lease assets were included in Right-of-use asset and finance lease assets were included in Property and equipment, net in the consolidated balance sheet. During the three months ended March 31, 2022, other than leases acquired in connection with acquisitions, there were no material changes in the terms and provisions of the Company’s operating leases in which the Company is a lessee. There were no material changes in finance lease assets and liabilities during the three months ended March 31, 2022.

(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 March 31, 2022, the remaining weighted average amortization period of the Company’s intangible assets was 15 years. Amortization of intangible assets for the three months ended March 31, 2022 and 2021 was $458.6 million and $253.4 million, respectively. The increase in amortization expense is primarily due to intangible assets acquired since the beginning of the prior-year period, including as a result of the Telxius Acquisition and the CoreSite Acquisition. Based on current exchange rates, the Company expects to record amortization expense as follows over the remaining current year and the five subsequent years:

7.    FAIR VALUE MEASUREMENTS
The Company determines the fair value of its financial instruments based on the fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Below are the three levels of inputs that may be used to measure fair value:
Level 1Quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.
Level 2Observable 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 3Unobservable 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 BasisThe 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:
 March 31, 2022December 31, 2021

_______________
(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 three months ended March 31, 2022, the Company recognized unrealized gains of $9.5 million for equity securities held as of March 31, 2022.
(2)Included in the carrying values of the corresponding debt obligations.

During the three months ended March 31, 2022, the Company made no changes to the methods described in note 11 to its consolidated financial statements included in the 2021 Form 10-K that it used to measure the fair value of its interest rate swap agreements. In January 2022, the interest rate swap agreements with certain lenders under the 2.250% Notes expired upon maturity of the underlying debt. As of March 31, 2022, there were no amounts outstanding under the interest rate swap agreements under the 2.250% Notes.

NOTES TO CONSOLIDATED AND CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(tabular amounts in millions, unless otherwise noted)
 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. There were no material impairments during the three months ended March 31, 2022 and 2021. There were no other items measured at fair value on a nonrecurring basis during the three months ended March 31, 2022 or 2021.
Fair Value of Financial Instruments—The Company’s financial instruments for which the carrying value reasonably approximates fair value at March 31, 2022 and December 31, 2021 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 March 31, 2022 and December 31, 2021, the carrying value of long-term obligations, including the current portion, was $43.5 billion and $43.3 billion, respectively. As of March 31, 2022, the fair value of long-term obligations, including the current portion, was $42.2 billion, of which $25.6 billion was measured using Level 1 inputs and $16.6 billion was measured using Level 2 inputs. As of December 31, 2021, the fair value of long-term obligations, including the current portion, was $44.1 billion, of which $28.5 billion was measured using Level 1 inputs and $15.6 billion was measured using Level 2 inputs.
8.    INCOME TAXES
The Company provides for income taxes at the end of each interim period based on the estimated effective tax rate (“ETR”) for the full fiscal year. Cumulative adjustments to the Company’s estimate are recorded in the interim period in which a change in the estimated annual ETR is determined. Under the provisions of the Internal Revenue Code of 1986, as amended, the Company may deduct amounts distributed to stockholders against the income generated by its real estate investment trust (“REIT”) operations. The Company continues to be subject to income taxes on the income of its domestic taxable REIT subsidiaries and income taxes in foreign jurisdictions where it conducts operations. In addition, the Company is able to offset certain income by utilizing its net operating losses, subject to specified limitations.
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.
The decrease in the income tax provision during the three months ended March 31, 2022 as compared to the three months ended March 31, 2021 was primarily attributable to the reversal of valuation allowances in certain jurisdictions. These valuation allowance reversals were recognized as a reduction to the income tax provision as the net related deferred tax assets were deemed realizable based on changes in facts and circumstances relevant to the assets’ recoverability.

As of March 31, 2022 and December 31, 2021, the total unrecognized tax benefits that would impact the ETR, if recognized, were approximately $99.2 million and $94.8 million, respectively. The amount of unrecognized tax benefits during the three months ended March 31, 2022 includes additions to the Company’s existing tax positions of $1.7 million and foreign currency exchange rate fluctuations of $2.5 million. Unrecognized tax benefits are expected to change over the next 12 months if certain tax matters ultimately settle with the applicable taxing jurisdiction during this time frame, as described in note 12 to the Company’s consolidated financial statements included in the 2021 Form 10-K. The impact of the amount of these changes to previously recorded uncertain tax positions could range from zero to $16.8 million.

The Company recorded the following penalties and income tax-related interest expense during the three months ended March 31, 2022 and 2021:
Three Months Ended March 31,
20222021
Penalties and income tax-related interest expense$7.3 $3.7 

As of March 31, 2022 and December 31, 2021, the total amount of accrued income tax related interest and penalties included in the consolidated balance sheets were $51.7 million and $42.3 million, respectively.
9.    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
15

AMERICAN TOWER CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED AND CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(tabular amounts in millions, unless otherwise noted)
amended (the “2007 Plan”), provides for the grant of non-qualified and incentive stock options, as well as restricted stock units, restricted stock and other stock-based awards. Exercise prices for non-qualified and incentive stock options are not less than the fair value of the underlying common stock on the date of grant. Equity awards typically vest ratably, generally over four years for time-based restricted stock units (“RSUs”) and stock options and three years for performance-based restricted stock units (“PSUs”). Stock options generally expire ten years from the date of grant. As of March 31, 2022, the Company had the ability to grant stock-based awards with respect to an aggregate of 5.2 million shares of common stock under the 2007 Plan. In connection with the CoreSite Acquisition, the Company assumed the remaining shares previously available for issuance under a plan approved by the CoreSite shareholders, which converted into 1.4 million shares of the Company’s common stock. These shares will be available for issuance under the 2007 Plan, however, will only be available for grants to certain employees and will not be available for issuance beyond the period when they would have been available under the CoreSite plan, or March 20, 2023, at which time they will no longer be available for grant. In addition, the Company maintains an employee stock purchase plan (the “ESPP”) pursuant to which eligible employees may purchase shares of the Company’s common stock on the last day of each bi-annual offering period at a 15% discount from the lower of the closing market value on the first or last day of such offering period. The offering periods run from June 1 through November 30 and from December 1 through May 31 of each year.
During the three months ended March 31, 2022 and 2021, the Company recorded the following stock-based compensation expense in selling, general, administrative and development expense:
Three Months Ended March 31,
 20222021
Stock-based compensation expense$56.7 $38.0 
Stock Options—As of March 31, 2022, there was no unrecognized compensation expense related to unvested stock options.
The Company’s option activity for the three months ended March 31, 2022 was as follows (shares disclosed in full amounts):

Exercised(99,367)
Forfeited 
Expired 
Outstanding as of March 31, 2022968,632 
Restricted Stock Units—As of March 31, 2022, total unrecognized compensation expense related to unvested RSUs granted under the 2007 Plan, including the CoreSite Replacement Awards (as defined below), was $260.9 million and is expected to be recognized over a weighted average period of approximately three 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). In December 2021, in connection with the CoreSite Acquisition, the Company assumed and converted certain equity awards previously granted by CoreSite under its equity plan into corresponding equity awards with respect to shares of the Company’s common stock (the “CoreSite Replacement Awards”). As of March 31, 2022, total unrecognized compensation expense related to the CoreSite Replacement Awards was $17.3 million and is expected to be recognized over a weighted average period of approximately two years.
Performance-Based Restricted Stock Units—During the three months ended March 31, 2022, the Company’s Compensation Committee (the “Compensation Committee”) granted an aggregate of 98,542 PSUs (the “2022 PSUs”) to its executive officers and established the performance metrics for these awards. During the years ended December 31, 2021 and 2020, the Compensation Committee granted an aggregate of 98,694 PSUs (the “2021 PSUs”) and 110,925 PSUs (the “2020 PSUs”), respectively, to its executive officers and established the performance metrics for these awards. During the year ended December 31, 2020, in connection with the retirement of the Company’s former Chief Executive Officer, an aggregate of 40,186 shares underlying the 2020 PSUs were forfeited, which included the target number of shares issuable at the end of the three-year performance period for such executive’s 2020 PSUs. Threshold, target and maximum parameters were established for the metrics for a three-year performance period with respect to each of the 2022 PSUs, the 2021 PSUs and the 2020 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
16

(tabular amounts in millions, unless otherwise noted)
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.

13.    COMMITMENTS AND CONTINGENCIES
Litigation—The Company periodically becomes involved in various claims, lawsuits and proceedings that are incidental to its business. In the opinion of Company management, after consultation with counsel, there are no matters currently pending that would, in the event of an adverse outcome, materially impact the Company’s consolidated financial position, results of operations or liquidity.
Verizon Transaction—In March 2015, the Company entered into an agreement with various operating entities of Verizon Communications Inc. (“Verizon”) that currently provides for the lease, sublease or management of approximately 11,250 wireless communications sites commencing March 27, 2015. The average term of the lease or sublease for all sites at the inception of the agreement was approximately 28 years, assuming renewals or extensions of the underlying ground leases for the sites. The Company has the option to purchase the leased sites in tranches, subject to the applicable lease, sublease or management rights upon its scheduled expiration. Each tower is assigned to an annual tranche, ranging from 2034 to 2047, which represents the outside expiration date for the sublease rights to the towers in that tranche. The purchase price for each tranche is a fixed amount stated in the lease for such tranche plus the fair market value of certain alterations made to the related towers. The aggregate purchase option price for the towers leased and subleased is approximately $5.0 billion. Verizon will occupy the sites as a tenant for an initial term of ten years with eight optional successive five-year terms; each such term shall be governed by standard master lease agreement terms established as a part of the transaction.
AT&T Transaction—The Company has an agreement with SBC Communications Inc., a predecessor entity to AT&T Inc. (“AT&T”), that currently provides for the lease or sublease of approximately 2,000 towers commencing between December 2000 and August 2004. Substantially all of the towers are part of the securitization transactions completed in March 2013 and March 2018. The average term of the lease or sublease for all communications 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 March 31, 2022, the Company has purchased an aggregate of approximately 400 of the subleased towers which are subject to the applicable agreement. 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.
On December 5, 2016, the Company received an income tax assessment of Essar Telecom Infrastructure Private Limited (“ETIPL”) from the India Income Tax Department (the “Tax Department”) for the fiscal year ending 2008 in the amount of INR 4.75 billion ($69.8 million on the date of assessment) related to capital contributions. The Company challenged the assessment before the Office of Commissioner of Income Tax - Appeals, which ruled in the Company’s favor in January 2018. However, the Tax Department has appealed this ruling at a higher appellate authority. The Company estimates that there is a more likely than not probability that the Company’s position will be sustained upon appeal. Accordingly, no liability has been recorded. Additionally, the assessment was made with respect to transactions that took place in the tax year commencing in 2007, prior to the Company’s acquisition of ETIPL. Under the Company’s definitive acquisition agreement with ETIPL, the seller is obligated to indemnify and defend the Company with respect to any tax-related liability that may arise from activities prior to March 31, 2010.

14.    ACQUISITIONS
Impact of current year acquisitions—The Company typically acquires communications sites and other communications infrastructure assets from wireless carriers or other tower operators and subsequently integrates those sites and related assets into its existing portfolio of communications sites and related assets. In the United States, the Company has also acquired data center facilities and related assets, including through the CoreSite Acquisition, as discussed below. The financial results of the Company’s acquisitions have been included in the Company’s consolidated statements of operations for the three months ended March 31, 2022 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.
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 acquired, with no recognition of goodwill.
For those acquisitions accounted for as business combinations, the Company recognizes acquisition and merger related expenses in the period in which they are incurred and services are received; for transactions accounted for as asset acquisitions, these costs are capitalized as part of the purchase price. Acquisition and merger related costs may include finder’s fees, advisory, legal, accounting, valuation and other professional or consulting fees and general administrative costs directly related to completing the transaction. Integration costs include incremental and non-recurring costs necessary to convert data and systems, retain employees and otherwise enable the Company to operate acquired businesses or assets efficiently. The Company records acquisition and merger related expenses for business combinations, as well as integration costs for all acquisitions, in Other operating expenses in the consolidated statements of operations.
During the three months ended March 31, 2022 and 2021, the Company recorded acquisition and merger related expenses for business combinations and non-capitalized asset acquisition costs and integration costs as follows:
Three Months Ended March 31,
20222021
Acquisition and merger related expenses$5.7 $34.6 
Integration costs$10.0 $16.6 
During the three months ended March 31, 2022 and 2021, the Company also recorded benefits of $1.6 million and $4.0 million, respectively, related to pre-acquisition contingencies and settlements.
2022 Transactions
The estimated aggregate impact of the acquisitions completed in 2022 on the Company’s revenues and gross margin for the three months ended March 31, 2022 was not material to the Company’s operating results. The revenues and gross margin amounts also reflect incremental revenues from the addition of new customers to communications infrastructure assets subsequent to the transaction date.
Other Acquisitions—During the three months ended March 31, 2022, the Company acquired a total of 27 communications sites, as well as other communications infrastructure assets, in the United States, Canada and Nigeria for an aggregate purchase price of $29.1 million. These acquisitions were accounted for as asset acquisitions.

Orange Acquisition—On November 28, 2019, the Company entered into definitive agreements with Orange S.A. for the acquisition of up to approximately 2,000 communications sites in France over a period of up to five years for total consideration in the range of approximately 500.0 million EUR to 600.0 million EUR (approximately $550.5 million to $660.5 million at the date of signing) to be paid over the five-year term. The Company completed the acquisition of 1,197 of these communications sites during the years ended December 31, 2020 and 2021. The remaining communications sites are expected to continue to close in tranches, subject to customary closing conditions.
2021 Transactions
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. In June 2021, the Company completed the acquisition of nearly 20,000 communications sites in Germany and Spain, for total consideration of approximately 6.3 billion EUR (approximately $7.7 billion at the date of closing), subject to certain post-closing adjustments and over 7,000 communications sites in Brazil, Peru, Chile and Argentina, for total consideration of approximately 0.9 billion EUR (approximately $1.1 billion at the date of closing), subject to certain post-closing adjustments.
On August 2, 2021, the Company completed the acquisition of the approximately 4,000 remaining communications sites in Germany pursuant to the Telxius Acquisition for 0.6 billion EUR (approximately $0.7 billion at the date of closing).
Of the aggregate purchase price, 243.3 million EUR (approximately $269.2 million), including post-closing adjustments, of deferred payments are due in September 2025 and are reflected in Other non-current liabilities in the consolidated balance sheet as of March 31, 2022. The acquired operations in Germany and Spain are included in the Europe property segment and the acquired operations in Brazil, Peru, Chile and Argentina are included in the Latin America property segment. The Telxius Acquisition was accounted for as a business combination and is subject to post-closing adjustments. During the three months ended March 31, 2022, certain adjustments were made to increase the purchase price by $2.6 million, decrease assets by $32.3 million and reduce liabilities by $31.9 million, with a corresponding increase in goodwill of $3.0 million. There were no other material post-closing adjustments. The full reconciliation and finalization of the assets acquired and liabilities assumed, including those subject to valuation, have not been completed and, as a result, there may be additional post-closing adjustments.

CoreSite Acquisition—On November 14, 2021, the Company entered into an agreement with CoreSite to acquire all issued and outstanding shares of CoreSite common stock at $170.00 per share. CoreSite’s portfolio consisted of 24 data center facilities and related assets in eight United States markets. On December 28, 2021, the Company completed the CoreSite Acquisition for total consideration of approximately $10.4 billion, including the assumption and repayment of CoreSite’s existing debt. The acquired assets and operations are included in the Data Centers segment. The CoreSite Acquisition was accounted for as a business combination and is subject to post-closing adjustments. Subsequent to the acquisition dates, certain adjustments were made to decrease assets by $0.2 million and reduce liabilities by $1.0 million, with a corresponding decrease in goodwill of $0.8 million. There were no other material post-closing adjustments. The full reconciliation and finalization of the assets acquired and liabilities assumed, including those subject to valuation, have not been completed and, as a result, there may be additional post-closing adjustments.

The following table presents the unaudited pro forma financial results as if the 2022 acquisitions had occurred on January 1, 2021 and the 2021 acquisitions had occurred on January 1, 2020. The pro forma results, to the extent available, are based on historical information, and accordingly may not fully reflect the current operations of the acquired business. In addition, the pro forma results do not include any anticipated cost synergies, costs or other integration impacts.

15.    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. This business is referred to as the Company’s property operations.
Data Centers—During the fourth quarter of 2021, as a result of the CoreSite Acquisition, the Company established the Data Centers segment as a reportable segment. The Data Centers segment relates to data center facilities and related assets that the Company owns and operates in the United States. The Data Centers segment offers different services from, and requires different resources, skill sets and marketing strategies than, the existing property operating segment in the U.S. & Canada. Prior to this revision, the Company operated in five property business segments: (i) U.S. & Canada property, (ii) Asia-Pacific property (iii) Africa property, (iii) Europe property and (iv) Latin America property.
The change in reportable segments had no impact on the Company’s consolidated financial statements for any prior periods. Historical financial information included in this Quarterly Report has been adjusted to reflect the change in reportable segments.
As of March 31, 2022, the Company’s property operations consisted of the following:
U.S. & Canada: property operations in Canada and the United States;
Asia-Pacific: property operations in Australia, Bangladesh, India and the Philippines;
Africa: property operations in Burkina Faso, Ghana, Kenya, Niger, Nigeria, South Africa and Uganda;
Europe: property operations in France, Germany, Poland and Spain;
Latin America: property operations in Argentina, Brazil, Chile, Colombia, Costa Rica, Mexico, Paraguay and Peru; and
Data Centers: data center property operations in the United States.

(tabular amounts in millions, unless otherwise noted)
Services—The Company’s Services segment offers tower-related services in the United States, including AZP and structural analysis, which primarily support its communications 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 to the Company’s consolidated financial statements included in the 2021 Form 10-K and as updated in note 1 above. 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 three months ended March 31, 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.

(tabular amounts in millions, unless otherwise noted)
If the Company undergoes a change of control and corresponding ratings decline, each as defined in the supplemental indenture for the Notes, the Company may be required to repurchase all of the 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.
The supplemental indenture contains certain covenants that restrict the Company’s ability to merge, consolidate or sell assets and its (together with its subsidiaries’) ability to incur liens. These covenants are subject to a number of exceptions, including that the Company and its subsidiaries may incur certain liens on assets, mortgages or other liens securing indebtedness if the aggregate amount of indebtedness secured by such liens does not exceed 3.5x Adjusted EBITDA, as defined in the supplemental indenture.

ITEM 2.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
This Quarterly Report on Form 10-Q (this “Quarterly Report”) contains forward-looking statements relating to our goals, beliefs, plans or current expectations and other statements that are not of historical facts. For example, when we use words such as “project,” “believe,” “anticipate,” “expect,” “forecast,” “estimate,” “intend,” “should,” “would,” “could,” “may” or other words that convey uncertainty of future events or outcomes, we are making forward-looking statements. Certain important factors may cause actual results to differ materially from those indicated by our forward-looking statements, including those set forth under the caption “Risk Factors” in Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2021 (the “2021 Form 10-K”). Forward-looking statements represent management’s current expectations and are inherently uncertain. We do not undertake any obligation to update forward-looking statements made by us.
The discussion and analysis of our financial condition and results of operations that follow are based upon our consolidated and condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). The preparation of our financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and the related disclosure of contingent assets and liabilities at the date of our financial statements. Actual results may differ from these estimates and such differences could be material to the financial statements. This discussion should be read in conjunction with our consolidated and condensed consolidated financial statements herein and the accompanying notes, information set forth under the caption “Critical Accounting Policies and Estimates” in the 2021 Form 10-K, and in particular, the information set forth therein under Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”
During the fourth quarter of 2021, as a result of the acquisition of CoreSite Realty Corporation (“CoreSite,” and the acquisition, the “CoreSite Acquisition”), we updated our reportable segments to add a Data Centers segment. The Data Centers segment is included within our property operations. We now report our results in seven segments – U.S. & Canada property (which includes all assets in the United States and Canada, other than our data center facilities and related assets), Asia-Pacific property, Africa property, Europe property, Latin America property, Data Centers and Services. We believe this change provides greater visibility into our operating segments and aligns our reporting with management’s current approach of allocating costs and resources, managing growth and profitability and assessing the operating performance of our business segments (see note 15 to our consolidated and condensed consolidated financial statements included in this Quarterly Report). This change applied to our business operations results beginning with the fourth quarter of 2021 and had no impact on our consolidated financial statements for any prior periods. Historical financial information included in Management’s Discussion and Analysis of Financial Condition and Results of Operations has been adjusted to reflect the change in reportable segments.
Overview
We are one of the largest global real estate investment trusts and a leading independent owner, operator and developer of multitenant communications real estate. Our primary business is the leasing of space on communications sites to wireless service providers, radio and television broadcast companies, wireless data providers, government agencies and municipalities and tenants in a number of other industries. In addition to the communications sites in our portfolio, we manage rooftop and tower sites for property owners under various contractual arrangements. We also hold other telecommunications infrastructure, fiber and property interests that we lease primarily to communications service providers and third-party tower operators, and, as discussed further below, we hold a portfolio of highly interconnected data center facilities and related assets in the United States. Our customers include our tenants, licensees and other payers. We refer to the business encompassing the above as our property operations, which accounted for 98% of our total revenues for the three months ended March 31, 2022 and includes our U.S. & Canada property, Asia-Pacific property, Africa property, Europe property, Latin America property and Data Centers segments.
We also offer tower-related services in the United States, including site application, zoning and permitting and structural analysis, which primarily support our site leasing business, including the addition of new tenants and equipment on our sites.

We operate in seven reportable segments: U.S. & Canada property, Asia-Pacific property, Africa property, Europe property, Latin America property, Data Centers and Services. In evaluating operating performance in each business segment, management uses, among other factors, segment gross margin and segment operating profit (see note 15 to our consolidated and condensed consolidated financial statements included in this Quarterly Report).
The 2021 Form 10-K contains information regarding management’s expectations of long-term drivers of demand for our communications sites, as well as key trends, which management believes provide valuable insight into our operating and financial resource allocation decisions. The discussion below should be read in conjunction with the 2021 Form 10-K and, in particular, the information set forth therein under Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Executive Overview.”
In most of our markets, our tenant leases with wireless carriers generally have initial non-cancellable terms of five to ten years with multiple renewal terms. Accordingly, the vast majority of the revenue generated by our property operations during the three months ended March 31, 2022 was recurring revenue that we should continue to receive in future periods. Most of our tenant leases for our communications sites have provisions that periodically increase the rent due under the lease, typically based on an annual fixed escalation (averaging approximately 3% in the United States) or an inflationary index in most of our international markets, or a combination of both. In addition, certain of our tenant leases provide for additional revenue primarily to cover costs (pass-through revenue), such as ground rent or power and fuel costs.
Based upon existing customer leases and foreign currency exchange rates as of March 31, 2022, we expect to generate over $61 billion of non-cancellable customer lease revenue over future periods, before the impact of straight-line lease accounting.
The revenues generated by our property operations may be affected by cancellations of existing tenant leases. As discussed above, most of our tenant leases with wireless carriers and broadcasters are multiyear contracts, which typically are non-cancellable; however, in some instances, a lease may be cancelled upon the payment of a termination fee. Revenue lost from either tenant lease cancellations or the non-renewal of leases or rent renegotiations, which we refer to as churn, has historically not had a material adverse effect on the revenues generated by our consolidated property operations. During the three months ended March 31, 2022, churn was approximately 6% of our tenant billings, primarily driven by churn in our U.S. & Canada property segment, as discussed below.
29


We expect that our churn rate in our U.S. & Canada property segment will remain elevated for a period of several years due to contractual lease cancellations and non-renewals by T-Mobile, including legacy Sprint Corporation leases, pursuant to the terms of our master lease agreement with T-Mobile US, Inc. (the “T-Mobile MLA”) entered into in September 2020.
As further set forth under the caption “Risk Factors” in Part I, Item 1A of the 2021 Form 10-K, the ongoing coronavirus (“COVID-19”) pandemic, as well as the response to mitigate its spread and effects, may adversely impact us and our customers and the demand for our communications infrastructure in the United States and globally. We have taken a variety of actions to ensure the continued availability of our communications infrastructure assets, while ensuring the safety and security of our employees, customers, vendors and surrounding communities. We will continue to actively monitor the situation and may take further actions as may be required by governmental authorities or that we determine are in the best interests of our employees, customers and business partners.
Non-GAAP Financial Measures
Included in our analysis of our results of operations are discussions regarding earnings before interest, taxes, depreciation, amortization and accretion, as adjusted (“Adjusted EBITDA”), Funds From Operations, as defined by the National Association of Real Estate Investment Trusts (“Nareit FFO”) attributable to American Tower Corporation common stockholders, Consolidated Adjusted Funds From Operations (“Consolidated AFFO”) and AFFO attributable to American Tower Corporation common stockholders.
We define Adjusted EBITDA as Net income before Income (loss) from equity method investments; Income tax benefit (provision); Other income (expense); Gain (loss) on retirement of long-term obligations; Interest expense; Interest income; Other operating income (expense); Depreciation, amortization and accretion; and stock-based compensation expense.
Nareit FFO attributable to American Tower Corporation common stockholders is defined as net income before gains or losses from the sale or disposal of real estate, real estate related impairment charges, real estate related depreciation, amortization and accretion and dividends on preferred stock, and including adjustments for (i) unconsolidated affiliates and (ii) noncontrolling interests. In this section, we refer to Nareit FFO attributable to American Tower Corporation common stockholders as “Nareit FFO (common stockholders).”
We define Consolidated AFFO as Nareit FFO (common stockholders) before (i) straight-line revenue and expense; (ii) stock-based compensation expense; (iii) the deferred portion of income tax and other income tax adjustments; (iv) non-real estate related depreciation, amortization and accretion; (v) amortization of deferred financing costs, capitalized interest, debt discounts and premiums and long-term deferred interest charges; (vi) other income (expense); (vii) gain (loss) on retirement of long-term obligations; (viii) other operating income (expense); and adjustments for (ix) unconsolidated affiliates and (x) noncontrolling interests, less cash payments related to capital improvements and cash payments related to corporate capital expenditures.
We define AFFO attributable to American Tower Corporation common stockholders as Consolidated AFFO, excluding the impact of noncontrolling interests on both Nareit FFO (common stockholders) and the other adjustments included in the calculation of Consolidated AFFO. In this section, we refer to AFFO attributable to American Tower Corporation common stockholders as “AFFO (common stockholders).”
Adjusted EBITDA, Nareit FFO (common stockholders), Consolidated AFFO and AFFO (common stockholders) are not intended to replace net income or any other performance measures determined in accordance with GAAP. None of Adjusted EBITDA, Nareit FFO (common stockholders), Consolidated AFFO or AFFO (common stockholders) represents cash flows from operating activities in accordance with GAAP and, therefore, these measures should not be considered indicative of cash flows from operating activities, as a measure of liquidity or a measure of funds available to fund our cash needs, including our ability to make cash distributions. Rather, Adjusted EBITDA, Nareit FFO (common stockholders), Consolidated AFFO and AFFO (common stockholders) are presented as we believe each is a useful indicator of our current operating performance. We believe that these metrics are useful to an investor in evaluating our operating performance because (1) each is a key measure used by our management team for decision making purposes and for evaluating our operating segments’ performance; (2) Adjusted EBITDA is a component underlying our credit ratings; (3) Adjusted EBITDA is widely used in the telecommunications real estate sector to measure operating performance as depreciation, amortization and accretion may vary significantly among companies depending upon accounting methods and useful lives, particularly where acquisitions and non-operating factors are involved; (4) Consolidated AFFO is widely used in the telecommunications real estate sector to adjust Nareit FFO (common
30


stockholders) for items that may otherwise cause material fluctuations in Nareit FFO (common stockholders) growth from period to period that would not be representative of the underlying performance of property assets in those periods; (5) each provides investors with a meaningful measure for evaluating our period-to-period operating performance by eliminating items that are not operational in nature; and (6) each provides investors with a measure for comparing our results of operations to those of other companies, particularly those in our industry.
Our measurement of Adjusted EBITDA, Nareit FFO (common stockholders), Consolidated AFFO and AFFO (common stockholders) may not, however, be fully comparable to similarly titled measures used by other companies. Reconciliations of Adjusted EBITDA, Nareit FFO (common stockholders), Consolidated AFFO and AFFO (common stockholders) to net income, the most directly comparable GAAP measure, have been included below.

The increase in depreciation, amortization and accretion expense for the three months ended March 31, 2022 was primarily attributable to the acquisition, lease or construction of new sites since the beginning of the prior-year period, including due to the Telxius Acquisition and the CoreSite Acquisition, which resulted in increases in property and equipment and intangible assets subject to amortization, partially offset by foreign currency exchange rate fluctuations.
Other Operating Expenses
 Three Months Ended March 31,Percent Increase (Decrease)
 20222021
Other operating expenses$26.1 $50.4 (48)%
The decrease in other operating expenses during the three months ended March 31, 2022 was primarily attributable to decreases in acquisition related costs, including pre-acquisition contingencies and settlements, of $33.0 million, partially offset by an increase in impairment charges and losses on sales or disposals of assets of $8.3 million.
Total Other (Income) Expense
 Three Months Ended March 31,Percent Increase (Decrease)
 20222021
Total other (income) expense$(0.1)$126.1 (100)%
Total other (income) expense consists primarily of interest expense and realized and unrealized foreign currency gains and losses. We record unrealized foreign currency gains or losses as a result of foreign currency exchange rate fluctuations primarily associated with our intercompany notes and similar unaffiliated balances denominated in a currency other than the subsidiaries’ functional currencies.
The change in total other (income) expense during the three months ended March 31, 2022 was primarily due to an increase in foreign currency gains of $147.4 million and a decrease in loss on retirement of debt of $25.7 million attributable to the repayment of all amounts outstanding under the securitizations assumed in connection with our acquisition of InSite Wireless Group, LLC (the “InSite Acquisition,” and the debt, the “InSite Debt”) in the prior-year period, partially offset by an increase in net interest expense of $56.9 million, primarily due to an increase in our average debt outstanding during the three months ended March 31, 2022 as compared to the prior-year period. Total other (income) expense during the three months ended March 31, 2022 also includes $9.5 million in unrealized gains from equity securities in the United States.
Income Tax Provision
 Three Months Ended March 31,Percent Increase (Decrease)
 20222021
Income tax provision$22.5 $50.3 (55)%
Effective tax rate3.1 %7.2 %
As a real estate investment trust for U.S. federal income tax purposes (“REIT”), we may deduct earnings distributed to stockholders against the income generated by our REIT operations. In addition, we are able to offset certain income by
36


utilizing our net operating losses (“NOLs”), subject to specified limitations. Consequently, the effective tax rate on income from continuing operations for each of the three months ended March 31, 2022 and 2021 differs from the federal statutory rate.
The decrease in the income tax provision during the three months ended March 31, 2022 was primarily attributable to the reversal of valuation allowances in certain jurisdictions. These valuation allowance reversals were recognized as a reduction to the income tax provision as the net related deferred tax assets were deemed realizable based on changes in facts and circumstances relevant to the assets’ recoverability.

(1)Included in these amounts are impairment charges of $5.8 million and $0.6 million, respectively.
(2)In 2015, we incurred charges in connection with certain tax elections wherein MIP Tower Holdings LLC, parent company to Global Tower Partners (“GTP”), would no longer operate as a separate REIT for federal and state income tax purposes. We finalized a settlement related to this tax election in the three month period ended March 31, 2022. We believe that these related transactions are nonrecurring, and do not believe it is an indication of our operating performance. Accordingly, we believe it is more meaningful to present Consolidated AFFO excluding these amounts.
(3)Includes gains on foreign currency exchange rate fluctuations of $242.1 million and $94.7 million, respectively.
(4)Primarily includes acquisition-related costs and integration costs. 
(5)Includes adjustments for the impact on both Nareit FFO attributable to American Tower Corporation common stockholders as well as the other line items included in the calculation of Consolidated AFFO.

The increase in net income for the three months ended March 31, 2022 was primarily due to (i) an increase in our operating profit, (ii) a decrease in other operating expenses, (iii) an increase in gains on foreign currency exchange rate fluctuations and (iv) a decrease in the income tax provision, partially offset by (a) an increase in depreciation, amortization and accretion expense and (b) an increase in interest expense. Net income for the three months ended March 31, 2021 included a loss on retirement of long-term obligations of $25.7 million, attributable to the repayment of the InSite Debt.
The increase in Adjusted EBITDA for the three months ended March 31, 2022 was primarily attributable to the increase in our gross margin, partially offset by an increase in SG&A, excluding the impact of stock-based compensation expense of $92.6 million.
The growth in Consolidated AFFO and AFFO attributable to American Tower Corporation common stockholders for the three months ended March 31, 2022 was primarily attributable to the increase in our operating profit, excluding the impact of straight-line accounting, partially offset by (i) increases in cash paid for taxes and cash paid for interest and (ii) an increase in capital improvement capital expenditures. The growth in AFFO attributable to American Tower Corporation common stockholders was also impacted by changes in noncontrolling interests held in Europe and Asia-Pacific since the beginning of the prior-year period.

Liquidity and Capital Resources
The information in this section updates as of March 31, 2022 the “Liquidity and Capital Resources” section of the 2021 Form 10-K and should be read in conjunction with that report.
Overview
During the three months ended March 31, 2022, our significant financing transactions included:
Repayment of debt assumed in connection with the CoreSite Acquisition, including senior unsecured notes previously entered into by CoreSite (the “CoreSite Debt”).
Redemption of our 2.250% senior unsecured notes due 2022 (the “2.250% Notes”) upon their maturity.
As a holding company, our cash flows are derived primarily from the operations of, and distributions from, our operating subsidiaries or funds raised through borrowings under our credit facilities and debt or equity offerings.
The following table summarizes the significant components of our liquidity (in millions):
As of March 31, 2022
Available under the 2021 Multicurrency Credit Facility$793.9 
Available under the 2021 Credit Facility1,450.0 
Letters of credit(24.7)
Total available under credit facilities, net$2,219.2 
Cash and cash equivalents1,941.5 
Total liquidity$4,160.7 
Subsequent to March 31, 2022, we made additional borrowings of $650.0 million and repayments of $720.0 million under the 2021 Credit Facility (as defined below) and repayments of $600.0 million under the 2021 Multicurrency Credit Facility (as defined below), including repayments of an aggregate of $1.2 billion under both facilities using proceeds from the issuance of the 3.650% Notes and the 4.050% Notes (each as defined below).
Summary cash flow information is set forth below (in millions):
Three Months Ended March 31,
 20222021
Net cash provided by (used for):
Operating activities$663.6 $1,092.7 
Investing activities(513.1)(438.7)
Financing activities(250.9)(480.0)
Net effect of changes in foreign currency exchange rates on cash and cash equivalents, and restricted cash28.5 (42.1)
Net (decrease) increase in cash and cash equivalents, and restricted cash$(71.9)$131.9 
We use our cash flows to fund our operations and investments in our business, including maintenance and improvements, communications site construction, managed network installations and acquisitions. Additionally, we use our cash flows to make distributions, including distributions of our REIT taxable income to maintain our qualification for taxation as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”). We may also repay or repurchase our existing indebtedness or equity from time to time. We typically fund our international expansion efforts primarily through a combination of cash on hand, intercompany debt and equity contributions.
As of March 31, 2022, we had total outstanding indebtedness of $43.7 billion, with a current portion of $5.3 billion. During the three months ended March 31, 2022, we generated sufficient cash flow from operations, together with borrowings under our credit facilities, debt issuances and cash on hand, to fund our acquisitions, capital expenditures and debt service obligations, as well as our required distributions. We believe the cash generated by operating activities during the year ending December 31, 2022, together with our borrowing capacity under our credit facilities, will be sufficient to fund our required distributions, capital expenditures, debt service obligations (interest and principal repayments) and signed acquisitions.     
39


We expect to finance the purchase price for the CoreSite Acquisition with both debt and equity and are evaluating a number of potential sources of equity funding, including common equity, mandatory convertible preferred equity and other convertible instruments and private capital partnerships, and discussions with respect to such private capital partnerships have continued to progress. No assurance can be given as to the completion of the above described financings on acceptable terms or at all.
Material Cash Requirements— There were no material changes to the Material Cash Requirements section of the 2021 Form 10-K.
As of March 31, 2022, we had $1.6 billion of cash and cash equivalents held by our foreign subsidiaries, of which $217.6 million was held by our joint ventures. While certain subsidiaries may pay us interest or principal on intercompany debt, it has not been our practice to repatriate earnings from our foreign subsidiaries primarily due to our ongoing expansion efforts and related capital needs. However, in the event that we do repatriate any funds, we may be required to accrue and pay certain taxes.
Cash Flows from Operating Activities
The decrease in cash provided by operating activities for the three months ended March 31, 2022 was primarily attributable to (i) changes in unearned revenue, (ii) an increase in cash required for working capital, primarily as a result of an increase in accounts receivable and a decrease in accounts payable, and (iii) increases in cash paid for interest and cash paid for taxes, partially offset by an increase in the operating profit of our property segments.
Cash Flows from Investing Activities
Our significant investing activities during the three months ended March 31, 2022 are highlighted below:
We spent $128.6 million for acquisitions, including payments made for acquisitions completed in 2021.
We spent $394.5 million for capital expenditures, as follows (in millions):
Discretionary capital projects (1)$187.6 
Ground lease purchases (2)56.5 
Capital improvements and corporate expenditures (3)29.0 
Redevelopment84.2 
Start-up capital projects37.2 
Total capital expenditures (4)$394.5 
_______________
(1)Includes the construction of 1,442 communications sites globally.
(2)Includes $10.1 million of perpetual land easement payments reported in Deferred financing costs and other financing activities in the cash flows from financing activities in our condensed consolidated statements of cash flows.
(3)Includes $1.4 million of finance lease payments reported in Repayments of notes payable, credit facilities, senior notes, secured debt, term loan and finance leases in the cash flows from financing activities in our condensed consolidated statements of cash flows.
(4)Net of purchase credits of $3.1 million on certain assets, which are recorded in investing activities in our condensed consolidated statements of cash flows.
We plan to continue to allocate our available capital, after satisfying our distribution requirements, among investment alternatives that meet our return on investment criteria, while maintaining our commitment to our long-term financial policies. Accordingly, we expect to continue to deploy capital through our annual capital expenditure program, including land purchases and new site and data center facility construction, and through acquisitions. We also regularly review our portfolios as to capital expenditures required to upgrade our infrastructure to our structural standards or address capacity, structural or permitting issues. 

40


We expect that our 2022 total capital expenditures will be as follows (in millions):

Discretionary capital projects (1)$820 to$850 
Ground lease purchases$230 to$250 
Capital improvements and corporate expenditures$170 to$180 
Redevelopment$500 to$520 
Start-up capital projects$280 to$300 
Total capital expenditures$2,000 to$2,100

(2)Includes the CoreSite Debt, which, as of December 31, 2021, included $875.0 million aggregate principal amount and a fair value adjustment of $80.1 million. During the three months ended March 31, 2022, we repaid all amounts outstanding under the CoreSite Debt.
(3)During the three months ended March 31, 2021, we liquidated our interests in a company held in France for total consideration of 2.2 million EUR (approximately $2.5 million at the date of redemption).
Repayment of 2.250% Senior Notes—On January 14, 2022, we repaid $600.0 million aggregate principal amount of the 2.250% Notes upon their maturity. The 2.250% Notes were repaid using borrowings under the 2021 Credit Facility. Upon completion of the repayment, none of the 2.250% Notes remained outstanding.
Offering of Senior Notes
3.650% Senior Notes and 4.050% Senior Notes Offering—On April 1, 2022, we completed a registered public offering of $650.0 million aggregate principal amount of 3.650% senior unsecured notes due 2027 (the “3.650% Notes”) and $650.0 million aggregate principal amount of 4.050% senior unsecured notes due 2032 (the “4.050% Notes,” and, together with the 3.650% Notes, the “Notes”). The net proceeds from this offering were approximately $1,282.6 million, after deducting commissions and estimated expenses. We used the net proceeds to repay existing indebtedness under the 2021 Multicurrency Credit Facility, the 2021 Credit Facility and the 2021 USD 364-Day Delayed Draw Term Loan.
The key terms of the Notes are as follows:

___________
(1)Accrued and unpaid interest on U.S. Dollar (“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.
41


(2)We 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 we redeem the Notes on or after the par call date, we will not be required to pay a make-whole premium.

If we undergo a change of control and corresponding ratings decline, each as defined in the supplemental indenture for the Notes, we may be required to repurchase all of the 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 our other senior unsecured debt and are structurally subordinated to all existing and future indebtedness and other obligations of our subsidiaries.
The supplemental indenture contains certain covenants that restrict our ability to merge, consolidate or sell assets and our (together with our subsidiaries’) ability to incur liens. These covenants are subject to a number of exceptions, including that we and our subsidiaries may incur certain liens on assets, mortgages or other liens securing indebtedness if the aggregate amount of indebtedness secured by such liens does not exceed 3.5x Adjusted EBITDA, as defined in the supplemental indenture.
Repayment of CoreSite Debt—On January 7, 2022, we repaid the entire amount outstanding under the CoreSite Debt, plus accrued and unpaid interest up to, but excluding, January 7, 2022, for an aggregate redemption price of $962.9 million, including $80.1 million of prepayment consideration and $7.8 million in accrued and unpaid interest. The repayment of the CoreSite Debt was funded with borrowings under the 2021 Multicurrency Credit Facility and cash on hand.
2021 Multicurrency Credit Facility—During the three months ended March 31, 2022, we borrowed an aggregate of $850.0 million under our $6.0 billion senior unsecured multicurrency revolving credit facility, as amended and restated in December 2021 (the “2021 Multicurrency Credit Facility”). We used the borrowings to repay outstanding indebtedness, including the CoreSite Debt, and for general corporate purposes. We currently have $3.5 million of undrawn letters of credit and maintain the ability to draw down and repay amounts under the 2021 Multicurrency Credit Facility in the ordinary course.

2021 Credit Facility—During the three months ended March 31, 2022, we borrowed an aggregate of $1.4 billion and repaid an aggregate of $260.0 million of revolving indebtedness under our $4.0 billion senior unsecured revolving credit facility, as amended and restated in December 2021 (the “2021 Credit Facility”). We used the borrowings to repay outstanding indebtedness, including the 2.250% Notes, and for general corporate purposes. We currently have $21.2 million of undrawn letters of credit and maintain the ability to draw down and repay amounts under the 2021 Credit Facility in the ordinary course.
As of March 31, 2022, the key terms under the 2021 Multicurrency Credit Facility, the 2021 Credit Facility, our $1.0 billion unsecured term loan, as amended and restated in December 2021 (the “2021 Term Loan”), our 825.0 million EUR unsecured term loan, as amended and restated in December 2021 (the “2021 EUR Three Year Delayed Draw Term Loan”), our $3.0 billion unsecured term loan entered into in December 2021 (the “2021 USD 364-Day Delayed Draw Term Loan”) and our $1.5 billion unsecured term loan entered into in December 2021 (the “2021 USD Two Year Delayed Draw Term Loan”) were as follows:

___________
(1)Represents interest rate above the London Interbank Offered Rate (“LIBOR”) for LIBOR based borrowings, interest rate above Euro Interbank Offer Rate (“EURIBOR”) for EURIBOR based borrowings and interest rate above the defined base rate for base rate borrowings, in each case based on our debt ratings.
(2)Currently borrowed at LIBOR for USD denominated borrowings and at EURIBOR for EUR denominated borrowings.
(3)Subject to two optional renewal periods.
(4)Currently borrowed at LIBOR.
(5)Currently borrowed at EURIBOR.

We must pay a quarterly commitment fee on the undrawn portion of each of the 2021 Multicurrency Credit Facility and the 2021 Credit Facility. The commitment fee for the 2021 Multicurrency Credit Facility and the 2021 Credit Facility ranges from 0.080% to 0.300% per annum, based upon our debt ratings, and is currently 0.110%.
The 2021 Multicurrency Credit Facility, the 2021 Credit Facility, the 2021 Term Loan, the 2021 EUR Three Year Delayed Draw Term Loan, the 2021 USD 364-Day Delayed Draw Term Loan and the 2021 USD Two Year Delayed Draw Term Loan do not require amortization of principal and may be paid prior to maturity in whole or in part at our option without penalty or premium. We have the option of choosing either a defined base rate, LIBOR or EURIBOR as the applicable base rate for borrowings under these bank facilities.
The loan agreements for each of the 2021 Multicurrency Credit Facility, the 2021 Credit Facility, the 2021 Term Loan, the 2021 EUR Three Year Delayed Draw Term Loan, the 2021 USD 364-Day Delayed Draw Term Loan and the 2021 USD Two Year Delayed Draw Term Loan contain certain reporting, information, financial and operating covenants and other restrictions (including limitations on additional debt, guaranties, sales of assets and liens) with which we must comply. Failure to comply with the financial and operating covenants of the loan agreements could not only prevent us from being able to borrow additional funds under the revolving credit facilities, but may constitute a default, which could result in, among other things, the amounts outstanding under the applicable agreement, including all accrued interest and unpaid fees, becoming immediately due and payable.
Stock Repurchase Programs—In March 2011, our Board of Directors approved a stock repurchase program, pursuant to which we are authorized to repurchase up to $1.5 billion of our common stock (the “2011 Buyback”). In December 2017, our Board of Directors approved an additional stock repurchase program, pursuant to which we are authorized to repurchase up to $2.0 billion of our common stock (the “2017 Buyback,” and, together with the 2011 Buyback, the “Buyback Programs”).
During the three months ended March 31, 2022, there were no repurchases under either of the Buyback Programs.
We expect to continue managing the pacing of the remaining approximately $2.0 billion under the Buyback Programs in response to general market conditions and other relevant factors. We expect to fund any further repurchases of our common stock through a combination of cash on hand, cash generated by operations and borrowings under our credit facilities. Repurchases under the Buyback Programs are subject to, among other things, us having available cash to fund the repurchases.
Sales of Equity Securities—We receive proceeds from sales of our equity securities pursuant to our employee stock purchase plan (the “ESPP”) and upon exercise of stock options granted under our equity incentive plan. During the three months ended March 31, 2022, we received an aggregate of $8.0 million in proceeds upon exercises of stock options.
2020 “At the Market” Stock Offering Program—In August 2020, we established an “at the market” stock offering program through which we may issue and sell shares of our common stock having an aggregate gross sales price of up to $1.0 billion (the “2020 ATM Program”). Sales under the 2020 ATM Program may be made by means of ordinary brokers’ transactions on the New York Stock Exchange or otherwise at market prices prevailing at the time of sale, at prices related to prevailing market prices or, subject to our specific instructions, at negotiated prices. We intend to use the net proceeds from any issuances under the 2020 ATM Program for general corporate purposes, which may include, among other things, the funding of acquisitions, additions to working capital and repayment or refinancing of existing indebtedness. As of March 31, 2022, we have not sold any shares of common stock under the 2020 ATM Program.
Distributions—As a REIT, we must annually distribute to our stockholders an amount equal to at least 90% of our REIT taxable income (determined before the deduction for distributed earnings and excluding any net capital gain). Generally, we have distributed, and expect to continue to distribute, all or substantially all of our REIT taxable income after taking into consideration our utilization of NOLs. We have distributed an aggregate of approximately $12.4 billion to our common stockholders, including the dividend to be paid in April 2022, primarily classified as ordinary income that may be treated as qualified REIT dividends under Section 199A of the Code for taxable years ending before 2026.
43


During the three months ended March 31, 2022, we paid $1.39 per share, or $633.5 million, to common stockholders of record. In addition, we declared a distribution of $1.40 per share, or $638.8 million, to be paid on April 29, 2022 to our common stockholders of record at the close of business on April 13, 2022.
The amount, timing and frequency of future distributions will be at the sole discretion of our Board of Directors and will depend on various factors, a number of which may be beyond our control, including our financial condition and operating cash flows, the amount required to maintain our qualification for taxation as a REIT and reduce any income and excise taxes that we otherwise would be required to pay, limitations on distributions in our existing and future debt and preferred equity instruments, our ability to utilize NOLs to offset our distribution requirements, limitations on our ability to fund distributions using cash generated through our taxable REIT subsidiaries and other factors that our Board of Directors may deem relevant.
We accrue distributions on unvested restricted stock units, which are payable upon vesting. As of March 31, 2022, the amount accrued for distributions payable related to unvested restricted stock units was $9.1 million. During the three months ended March 31, 2022, we paid $6.6 million of distributions upon the vesting of restricted stock units.
Factors Affecting Sources of Liquidity    
As discussed in the “Liquidity and Capital Resources” section of the 2021 Form 10-K, our liquidity depends on our ability to generate cash flow from operating activities, borrow funds under our credit facilities and maintain compliance with the contractual agreements governing our indebtedness. We believe that the debt agreements discussed below represent our material debt agreements that contain covenants, our compliance with which would be material to an investor’s understanding of our financial results and the impact of those results on our liquidity.
Restrictions Under Loan Agreements Relating to Our Credit Facilities—The loan agreements for the 2021 Multicurrency Credit Facility, the 2021 Credit Facility, the 2021 Term Loan, the 2021 EUR Three Year Delayed Draw Term Loan, the 2021 USD 364-Day Delayed Draw Term Loan and the 2021 USD Two Year Delayed Draw Term Loan contain certain financial and operating covenants and other restrictions applicable to us and our subsidiaries that are not designated as unrestricted subsidiaries on a consolidated basis. These restrictions include limitations on additional debt, distributions and dividends, guaranties, sales of assets and liens. The loan agreements also contain covenants that establish financial tests with which we and our restricted subsidiaries must comply related to total leverage and senior secured leverage, as set forth in the table below. As of March 31, 2022, we were in compliance with each of these covenants.

Under the terms of the agreements for the 2021 Multicurrency Credit Facility, the 2021 Credit Facility, the 2021 Term Loan, the 2021 EUR Three Year Delayed Draw Term Loan, the 2021 USD 364-Day Delayed Draw Term Loan and the 2021 USD Two Year Delayed Draw Term Loan, the Telxius Acquisition and the CoreSite Acquisition are designated as a Qualified Acquisitions, whereby our Total Debt to Adjusted EBITDA ratio was adjusted to not exceed 7.50 to 1.00 for four fiscal quarters following consummation of the Telxius Acquisition, which began with the quarter ended June 30, 2021 and for four fiscal quarters following consummation of the CoreSite Acquisition, which began with the quarter ended December 31, 2021. The loan agreements for our credit facilities also contain reporting and information covenants that require us to provide financial and operating information to the lenders within certain time periods. If we are unable to provide the required information on a timely basis, we would be in breach of these covenants.
Failure to comply with the financial maintenance tests and certain other covenants of the loan agreements for our credit facilities could not only prevent us from being able to borrow additional funds under these credit facilities, but may also
44


constitute a default under these credit facilities, which could result in, among other things, the amounts outstanding, including all accrued interest and unpaid fees, becoming immediately due and payable. If this were to occur, we may not have sufficient cash on hand to repay such indebtedness. The key factors affecting our ability to comply with the debt covenants described above are our financial performance relative to the financial maintenance tests defined in the loan agreements for these credit facilities and our ability to fund our debt service obligations. Based upon our current expectations, we believe our operating results during the next 12 months will be sufficient to comply with these covenants.
Restrictions Under Agreements Relating to the 2015 Securitization and the Trust Securitizations—The indenture and related supplemental indenture governing the American Tower Secured Revenue Notes, Series 2015-2, Class A (the “Series 2015-2 Notes”) issued by GTP Acquisition Partners I, LLC (“GTP Acquisition Partners”) in a private securitization transaction in May 2015 (the “2015 Securitization”) and the loan agreement related to the securitization transactions completed in March 2013 (the “2013 Securitization”) and March 2018 (the “2018 Securitization” and, together with the 2013 Securitization, the “Trust Securitizations”) include certain financial ratios and operating covenants and other restrictions customary for transactions subject to rated securitizations. Among other things, GTP Acquisition Partners and American Tower Asset Sub, LLC and American Tower Asset Sub II, LLC (together, the “AMT Asset Subs”) are prohibited from incurring other indebtedness for borrowed money or further encumbering their assets, subject to customary carve-outs for ordinary course trade payables and permitted encumbrances (as defined in the applicable agreements).
Under the agreements, amounts due will be paid from the cash flows generated by the assets securing the Series 2015-2 Notes or the assets securing the nonrecourse loan that secures the Secured Tower Revenue Securities, Series 2013-2A (the “Series 2013-2A Securities”), Secured Tower Revenue Securities, Series 2018-1, Subclass A (the “Series 2018-1A Securities”), and the 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”) issued in the Trust Securitizations (the “Loan”), as applicable, which must be deposited into certain reserve accounts, and thereafter distributed, solely pursuant to the terms of the applicable agreement. On a monthly basis, after payment of all required amounts under the applicable agreement, subject to the conditions described in the table below, the excess cash flows generated from the operation of such assets are released to GTP Acquisition Partners or the AMT Asset Subs, as applicable, which can then be distributed to, and used by, us. As of March 31, 2022, $292.7 million held in such reserve accounts was classified as restricted cash.
Certain information with respect to the 2015 Securitization and the Trust Securitizations is set forth below. The debt service coverage ratio (“DSCR”) 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 Series 2015-2 Notes or the Loan, as applicable, that will be outstanding on the payment date following such date of determination.

(1)Based on the net cash flow of the applicable issuer or borrower as of March 31, 2022 and the expenses payable over the next 12 months on the Series 2015-2 Notes or the Loan, as applicable.
(2)Once triggered, a Cash Trap DSCR condition continues to exist until the DSCR exceeds the Cash Trap DSCR for two consecutive calendar quarters. During a Cash Trap DSCR condition, 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 applicable issuer or borrower. 
(3)An amortization period commences if the DSCR is equal to or below 1.15x (the “Minimum DSCR”) at the end of any calendar quarter and continues to exist until the DSCR exceeds the Minimum DSCR for two consecutive calendar quarters.
(4)No amortization period is triggered if the outstanding principal amount of a series has not been repaid in full on the applicable anticipated repayment date. However, in such event, additional interest will accrue on the unpaid principal balance of the applicable series, and such series will begin to amortize on a monthly basis from excess cash flow.
(5)An amortization period exists if the outstanding principal amount has not been paid in full on the applicable anticipated repayment date and continues to exist until such principal has been repaid in full.

A failure to meet the noted DSCR tests could prevent GTP Acquisition Partners or the AMT Asset Subs from distributing excess cash flow to us, which could affect our ability to fund our capital expenditures, including tower construction and acquisitions, and to meet REIT distribution requirements. 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 Series 2015-2 Notes or the Loan, as applicable, on each monthly payment date, and so would not be available for distribution to us. Further, additional interest will begin to accrue with respect to the Series 2015-2 Notes or subclass of the Loan from and after the anticipated repayment date at a per annum rate determined in accordance with the applicable agreement. With respect to the Series 2015-2 Notes, upon the occurrence of, and during, an event of default, the applicable trustee may, in its discretion or at the direction of holders of more than 50% of the aggregate outstanding principal of the Series 2015-2 Notes, declare the Series 2015-2 Notes immediately due and payable, in which case any excess cash flow would need to be used to pay holders of such notes. Furthermore, if GTP Acquisition Partners or the AMT Asset Subs were to default on the Series 2015-2 Notes or the Loan, the applicable trustee may seek to foreclose upon or otherwise convert the ownership of all or any portion of the 3,531 communications sites that secure the Series 2015-2 Notes or the 5,113 broadcast and wireless communications towers and related assets that secure the Loan, respectively, in which case we could lose such sites and the revenue associated with those assets.
As discussed above, we use our available liquidity and seek new sources of liquidity to fund capital expenditures, future growth and expansion initiatives, satisfy our distribution requirements and repay or repurchase our debt. If we determine that it is desirable or necessary to raise additional capital, we may be unable to do so, or such additional financing may be prohibitively expensive or restricted by the terms of our outstanding indebtedness. Additionally, as further discussed under the caption “Risk Factors” in Item 1A of the 2021 Form 10-K, extreme market volatility and disruption caused by the COVID-19 pandemic may impact our ability to raise additional capital through debt financing activities or our ability to repay or refinance maturing liabilities, or impact the terms of any new obligations. If we are unable to raise capital when our needs arise, we may not be able to fund capital expenditures, future growth and expansion initiatives, satisfy our REIT distribution requirements and debt service obligations, or refinance our existing indebtedness.
In addition, our liquidity depends on our ability to generate cash flow from operating activities. As set forth under the caption “Risk Factors” in Item 1A of the 2021 Form 10-K, we derive a substantial portion of our revenues from a small number of customers and, consequently, a failure by a significant customer to perform its contractual obligations to us could adversely affect our cash flow and liquidity.
For more information regarding the terms of our outstanding indebtedness, please see note 8 to our consolidated financial statements included in the 2021 Form 10-K.
Critical Accounting Policies and Estimates
Management’s discussion and analysis of financial condition and results of operations are based upon our consolidated and condensed consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, as well as related disclosures of contingent assets and liabilities. We evaluate our policies and estimates on an ongoing basis, including those related to impairment of long-lived assets, asset retirement obligations, revenue recognition, rent expense, income taxes and accounting for business combinations and acquisitions of assets, as further discussed in the 2021 Form 10-K. Management bases its estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying amounts of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
46


We have reviewed our policies and estimates to determine our critical accounting policies for the three months ended March 31, 2022. We have made no material changes to the critical accounting policies described in the 2021 Form 10-K.
During the three months ended March 31, 2022, no potential goodwill impairment was identified as the fair value of each of our reporting units was in excess of its carrying amount.

ITEM 3.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Interest Rate Risk
As of March 31, 2022, we have three interest rate swap agreements related to a portion of our 3.000% senior unsecured notes due 2023 (the “3.000% Notes”). These swaps have been designated as fair value hedges, have an aggregate notional amount of $500.0 million and an interest rate of one-month LIBOR plus applicable spreads and expire in June 2023.
Changes in interest rates can cause interest charges to fluctuate on our variable rate debt. Variable rate debt as of March 31, 2022 consisted of $5.2 billion under the 2021 Multicurrency Credit Facility, $2.6 billion under the 2021 Credit Facility, $1.0 billion under the 2021 Term Loan, $3.0 billion under the 2021 USD 364-Day Delayed Draw Term Loan, $913.0 million under the 2021 EUR Three Year Delayed Draw Term Loan, $1.5 billion under the 2021 USD Two Year Delayed Draw Term Loan and $500.0 million under the interest rate swap agreements related to the 3.000% Notes. A 10% increase in current interest rates would result in an additional $5.4 million of interest expense for the three months ended March 31, 2022.
Foreign Currency Risk
We are exposed to market risk from changes in foreign currency exchange rates primarily in connection with our foreign subsidiaries and joint ventures internationally. Any transaction denominated in a currency other than the U.S. Dollar is reported in U.S. Dollars at the applicable exchange rate. All assets and liabilities are translated into U.S. Dollars at exchange rates in effect at the end of the applicable fiscal reporting period and all revenues and expenses are translated at average rates for the period. The cumulative translation effect is included in equity as a component of Accumulated other comprehensive loss. We may enter into additional foreign currency financial instruments in anticipation of future transactions to minimize the impact of foreign currency exchange rate fluctuations. For the three months ended March 31, 2022, 44% of our revenues and 49% of our total operating expenses were denominated in foreign currencies.
As of March 31, 2022, we have incurred intercompany debt that is not considered to be permanently reinvested and similar unaffiliated balances that were denominated in a currency other than the functional currency of the subsidiary in which it is recorded. As this debt had not been designated as being a long-term investment in nature, any changes in the foreign currency exchange rates will result in unrealized gains or losses, which will be included in our determination of net income. An adverse change of 10% in the underlying exchange rates of our unsettled intercompany debt and similar unaffiliated balances would result in $48.1 million of unrealized losses that would be included in Other expense in our consolidated statements of operations for the three months ended March 31, 2022. As of March 31, 2022, we have 7.3 billion EUR (approximately $8.0 billion) denominated debt outstanding. An adverse change of 10% in the underlying exchange rates of our outstanding EUR debt would result in $0.9 billion of foreign currency losses that would be included in Other expense in our consolidated statements of operations for the three months ended March 31, 2022.
ITEM 4.CONTROLS AND PROCEDURES
Disclosure Controls and Procedures
We have established disclosure controls and procedures designed to ensure that material information relating to us, including our consolidated subsidiaries, is made known to the officers who certify our financial reports and to other members of senior management and the Board of Directors.
Our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), as of the end of the period covered by this Quarterly Report. Based on this evaluation, our principal executive officer and principal financial officer concluded that these disclosure controls and procedures were effective as of March 31, 2022 and designed to ensure that the information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the requisite time periods specified in the applicable rules and forms, and that it is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure.
48


Changes in Internal Control over Financial Reporting
There have been no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) during the fiscal quarter ended March 31, 2022 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. As permitted by the rules and regulations of the Securities and Exchange Commission, we excluded from our assessment the internal control over financial reporting at Telxius and CoreSite, which were acquired in 2021, for the year ended December 31, 2021. We consider Telxius and CoreSite to be material to our results of operations, financial position and cash flows, and we are in the process of integrating the internal control procedures of Telxius and CoreSite into our internal control structure.

49


PART II. OTHER INFORMATION
ITEM 1.LEGAL PROCEEDINGS
We periodically become involved in various claims and lawsuits that are incidental to our business. In the opinion of management, after consultation with counsel, there are no matters currently pending that would, in the event of an adverse outcome, have a material impact on our consolidated financial position, results of operations or liquidity.

ITEM 1A.RISK FACTORS
There were no material changes to the risk factors disclosed in Item 1A of the 2021 Form 10-K.
