NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS-Unaudited (Continued)
(Tabular dollars in thousands, except per share amounts)

Recent Accounting Pronouncements Not Yet Adopted
In May 2014, the FASB released updated guidance regarding the recognition of revenue from contracts with customers, exclusive of those contracts within lease accounting. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.  To achieve that core principle, an entity should apply the following steps: (1) identify the contracts with the customer; (2) identify the performance obligations in the contract; (3) determine the contract price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when (or as) the entity satisfies a performance obligation.  This guidance is effective for the Company on January 1, 2018, following the FASB's July 2015 decision to defer the effective date of the standard by one year.   This guidance is required to be applied, at the Company's election, either (1) retrospectively to each prior reporting period presented, or (2) with the cumulative effect being recognized at the date of initial application. The Company expects to adopt the guidance effective January 1, 2018 with the cumulative effect being recognized at the date of initial application, and doesNo new accounting pronouncements issued but not expect the guidanceyet adopted are expected to have a material impact on itsthe Company's condensed consolidated financial statements.
In February 2016,
3.Revenues
Site rental revenues
The Company generates site rental revenues from its core business by providing tenants with access, including space or capacity, to its shared communications infrastructure via long-term tenant contracts in various forms, including lease, license, sublease and service agreements. Providing such access over the FASB issued new guidancelength of the tenant contract term represents the Company’s sole performance obligation under its tenant contracts.
Site rental revenues from the Company's tenant contracts are recognized on a straight-line, ratable basis over the fixed, non-cancelable term of the relevant tenant contract, which generally ranges from five to 15 years for wireless tenants and three to 20 years for the Company's fiber solutions tenants (including from organizations with high-bandwidth and multi-location demands), regardless of whether the payments from the tenant are received in equal monthly amounts during the life of the tenant contract. Certain of the Company's tenant contracts contain (1) fixed escalation clauses (such as fixed dollar or fixed percentage increases) or inflation-based escalation clauses (such as those tied to the CPI), (2) multiple renewal periods exercisable at the tenant's option and (3) only limited termination rights at the applicable tenant's option through the current term. If the payment terms call for fixed escalations, upfront payments, or rent-free periods, the revenue is recognized on a straight-line basis over the fixed, non-cancelable term of the agreement. When calculating straight-line rental revenues, the Company considers all fixed elements of tenant contractual escalation provisions, even if such escalation provisions contain a variable element in addition to a minimum. The Company's assets related to straight-line site rental revenues include current amounts of $174 million included in "Other current assets" and non-current amounts of $1.4 billion included in "Deferred site rental receivables" as of June 30, 2021. Amounts billed or received prior to being earned are deferred and reflected in "Deferred revenues" and "Other long-term liabilities." Amounts to which the Company has an unconditional right to payment, which are related to both satisfied or partially satisfied performance obligations, are recorded within "Receivables, net" on the recognition, measurement, presentation and disclosure of leases. The new guidance requires lessees to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments for all leases with a term greater than 12 months. The accounting for lessors remains largely unchanged from existing guidance. This guidance is effective for the Company as of January 1, 2019 and is required to be applied using a modified retrospective approach for all leases existing at, or entered into after, the beginning of the earliest comparative period presented. Early adoption is permitted, however, the Company does not expect to early adopt the new guidance. The Company (1) has established and is progressing through the various steps of a cross functional project plan to assess the impact of the standard; (2) expects this guidance to have a material impact on itsCompany's condensed consolidated balance sheet duesheet.
Services and other revenues
As part of the Company’s effort to provide comprehensive communications infrastructure solutions, as an ancillary business, the Company offers certain services primarily relating to its Towers segment, predominately consisting of (1) site development services and (2) installation services. Upon contract commencement, the Company assesses its services to tenants and identifies performance obligations for each promise to provide a distinct service.
The Company may have multiple performance obligations for site development services, which primarily include: structural analysis, zoning, permitting and construction drawings. For each of the above performance obligations, services revenues are recognized at completion of the applicable performance obligation, which represents the point at which the Company believes it has transferred goods or services to the additiontenant. The revenue recognized is based on an allocation of right-of-use assetsthe transaction price among the performance obligations in a respective contract based on estimated standalone selling price. The volume and mix of site development services may vary among contracts and may include a combination of some or all of the above performance obligations. Payments generally are due within 45 to 60 days and generally do not contain variable-consideration provisions. The transaction price for the Company's tower installation services consists of amounts for (1) permanent improvements to the Company's towers that represent a lease liabilities for all lessee arrangements withcomponent and (2) the performance of the service. Amounts under the Company's tower installation service agreements that represent a term greater than 12 months;lease component are recognized as site rental revenues on a straight-line basis over the length of the associated estimated lease term. For the performance of the installation service, the Company has one performance obligation, which is satisfied at the time of the applicable installation or augmentation and (3) continuesrecognized as services and other revenues. Since performance obligations are typically satisfied prior to assess additional impacts

receiving payment from tenants, the unconditional right to itspayment is recorded within "Receivables, net" on the Company’s condensed consolidated financial statements, includingbalance sheet. The vast majority of the Company’s services generally have a duration of one year or less.
Additional information on revenues
As of both January 1, 2021 and June 30, 2021, $2.8 billion of unrecognized revenue was reported in "Deferred revenues" and "Other long-term liabilities" on our condensed consolidated statementbalance sheet. During the six months ended June 30, 2021, approximately $315 million of operations and the condensed consolidated statementJanuary 1, 2020 unrecognized revenue balance was recognized as revenue. During the six months ended June 30, 2020, approximately $300 million of cash flows.the January 1, 2020 unrecognized revenue balance was recognized as revenue.
In February 2017,The following table is a summary of the FASB issued new guidance which clarifies the scope and application on accounting for the de-recognition of non-financial assets and in substance non-financial assets, including sales and partial sales of real estate assets. The new guidance also eliminates the existing industry specific guidance for partial sales of real estate, and requires full gain recognition upon partial sales of real estate. The guidance is effective fornon-cancelable contracted amounts owed to the Company by tenants pursuant to tenant contracts in effect as of January 1, 2018. The guidance may be early adopted, but must be adopted concurrently with the FASB's May 2014 guidance on revenue from contracts with customers. The guidance is required to be applied, at the Company's election, either (1) retrospectively to each prior reporting period presented or (2) with the cumulative effect being recognized at the date of initial application. The Company does not expect this guidance to have a material impact on its condensed consolidated financial statements.June 30, 2021.

The Company also may be subject to certain federal, state, local and foreign taxes on its income and assets, including (1) alternative minimum taxes, (2) taxes on any undistributed income, (3)(2) taxes related to the TRSs, (4) certain state, local, or foreign income taxes, (5)(3) franchise taxes, (6)(4) property taxes, and (7)(5) transfer taxes. In addition, the Company could inunder certain circumstances be required to pay an excise or penalty tax, which could be significant in amount, in order to utilize one or more relief provisions under the Internal Revenue Code of 1986, as amended, ("Code") to maintain qualification for taxation as a REIT.

The Company has received notices of claims and has been named as one of several defendants in lawsuits stemming from an April 2019 gas leak explosion in Durham, North Carolina, which occurred near an area where the Company's subcontractors were installing fiber. The explosion resulted in two fatalities, physical injuries (some of which were serious), and property damage to surrounding buildings and businesses. Currently, the Company is unable to determine the likelihood of an outcome or estimate a range of possible losses, if any, related to these lawsuits.
New York State Department of Transportation
In 2019, the State of New York passed legislation authorizing the Department of Transportation ("NYSDOT") to enter into agreements with any fiber provider for the use and occupancy of the state right-of-way for fiber optic lines. The legislation authorizes the NYSDOT to charge a fee of up to fair market value for such use and occupancy. To date, the Company has paid fees relating to newly deployed fiber lines but has not been required to pay, and has not recognized any costs in connection with, any fees relating to previously outstanding 4.50% Mandatory Convertible Preferred Stock were excluded fromdeployed fiber lines.

General Overview
Overview
We own, operate and lease shared wirelesscommunications infrastructure that has been acquired or constructed over time and is geographically dispersed throughout the U.S., and which consists ofincluding approximately (1) approximately 40,000 towers and (2) over 60,00080,000 route miles of fiber after giving effect to the Lightower Acquisition, primarily supporting small cell networkscells and fiber based solutions.
Our towers have a significant presence in the top 100 basic trading areas ("BTAs"), and the majority of our small cells and fiber is located in major metropolitan areas. Site rental revenues represented 84%90% of our thirdsecond quarter 20172021 consolidated net revenues. Our Towers operating segment and Small Cells operatingFiber segment accounted for 81%67% and 19%33%, respectively, of our thirdsecond quarter 20172021 site rental revenues. Within our Fiber segment, 70% and 30% of our second quarter 2021 Fiber site rental revenues related to fiber solutions and small cells, respectively. See note 10 to our condensed consolidated financial statements. The vast majority of our site rental revenues is of a recurring nature and was contracted for in a prior year.is subject to long-term tenant contracts with our tenants.
Strategy
OurAs a leading provider of shared communications infrastructure in the U.S., our strategy is to create long-term stockholder value via a combination of (1) growing cash flows generated from our existing portfolio of wirelesscommunications infrastructure, (2) returning a meaningful portion of our cash providedgenerated by operating activities to our common stockholders in the form of dividends and (3) investing capital efficiently to grow cash flows and long-term dividends per share. Our strategy is based, in part, on our belief that the U.S. is the most attractive market for shared communications infrastructure investment with the greatest long-term growth potential. We measure our efforts to create "long-term stockholder value" by the combined payment of dividends to stockholders and growth in our per shareper-share results. The key elements of our strategy are to:
Grow cash flows from our wirelessexisting communications infrastructure. We seek to maximize ourare focused on maximizing the recurring site rental cash flows by workinggenerated from providing our tenants with our customers to provide them quicklong-term access to our wirelessshared infrastructure and entering into associated long-term leases.assets, which we believe is the core driver of value for our stockholders. Tenant additions or modifications of existing tenant equipment (collectively, "tenant additions") enable our customerstenants to expand coverage and capacity in order to meet increasing demand for wireless connectivity,data while generating high incremental returns for our business. We believe our product offerings of towers and small cells provide a comprehensive solution to our customers'wireless tenants' growing connectivitynetwork needs through our shared wirelesscommunications infrastructure model, which is an efficient and cost effectivecost-effective way to serve our customers. We alsotenants. Additionally, we believe that there will be considerable future demand for our wireless infrastructure based on the location ofability to share our wireless infrastructurefiber assets across multiple tenants to deploy both small cells and the rapid growth in wireless connectivity, which will leadoffer fiber solutions allows us to future growth in the wireless industry.

Return cash providedgenerated by operating activities to common stockholders in the form of dividends. We believe that distributing a meaningful portion of our cash providedgenerated by operating activities appropriately provides common stockholders with increased certainty for a portion of expected long-term stockholder value while still retainingallowing us to retain sufficient flexibility to invest in our business and deliver growth. We believe this decision reflects the translation of the high-quality, long-term contractual cash flows of our business into stable capital returns to common stockholders.
Invest capital efficiently to grow cash flows and long-term dividends per share. We In addition to adding tenants to existing communications infrastructure, we seek to invest our available capital, including the net cash providedgenerated by our operating activities and external financing sources, in a manner that will increase long-term stockholder value on a risk-adjusted basis. These investments include constructing and acquiring new communications infrastructure that we expect will generate future cash flow growth and attractive long-term returns by adding tenants to those assets over time. Our historical investments have included the following (in no particular order):
construction of towers, fiber and small cells;
acquisitions of towers, fiber and small cells;
acquisitions of land interests (which primarily relate to land assets under towers);

purchases of shares of our common stock from time to time;

We believe that such demand for our wirelesscommunications infrastructure will continue, will result in growth of our cash flows due to tenant additions on our existing wirelesscommunications infrastructure, and will create other growth opportunities for us, such as demand for new wireless infrastructure.newly constructed or acquired communications infrastructure, as described above. Further, we seek to augment the long-term value creation associated with growing our recurring site rental cash flows by offering certain ancillary site development and installation services within our Towers segment.
Highlights of Business Fundamentals and Results
The following are certain highlights of our business fundamentals and results as of and for the nine months ended September 30, 2017.
We operate as a REIT for U.S. federal income tax purposes.purposes
As a REIT, we are generally entitled to a deduction for dividends that we pay and therefore are not subject to U.S. federal corporate income tax on our taxable income that is distributed to our stockholders.
To qualify and be taxed as a REIT, we will generally be required to distribute at least 90% of our REIT taxable income, after the utilization of our NOLs (determined without regard to the dividends paid deduction and excluding net capital gain), each year to our stockholders.
See note 6 to our condensed consolidated financial statements for further discussion of our REIT status.

See note 6 to our condensed consolidated financial statements for further discussion of our REIT status.
Potential growth resulting from wireless network expansion and new entrants caused bythe increasing demand for data
We expect existing and potential new tenant demand for our communications infrastructure will result from (1) new technologies, (2) increased usage of mobile entertainment, mobile internet, and machine-to-machine applications, (3) adoption of other emerging and embedded wireless devices (including smartphones, laptops, tablets, wearables and other devices), (4) increasing smartphone penetration, (5) wireless carrier focus on expanding both network quality and capacity, including the use of both towers and small cells, (6) the adoption of other bandwidth-intensive applications (such as cloud services and video communications), (7) the availability of additional spectrum and (8) increased government initiatives to support connectivity throughout the U.S.
We expect wireless carriers will continue their focus on improving network quality and expanding capacity by utilizing a combination of towers and small cells solutions. We believe our product offerings of towers and small cells provide a comprehensive wireless solution to our customers' growing wireless infrastructure needs.

Significant cash flows from operations
Net cash provided by operating activities was $1.4 billion.
In addition to the positive impact of contractual escalators, we expect to grow our core business of providing access to our wireless infrastructure as a result of future anticipated additional demand for our wireless infrastructure.
Net cash provided by operating activities was $1.4 billion for the six months ended June 30, 2021.
In addition to the positive impact of contractual escalators, we expect to grow our core business of providing access to our communications infrastructure as a result of future anticipated additional demand for our communications infrastructure.
Returning cash flows provided by operations to stockholders in the form of dividends
During each of the first three quarters of 2017,
During the second quarter of 2021, we paid a common stock dividend of $1.33 per share, totaling approximately $1.2 billion.
In August 2021, our board of directors declared a quarterly common stock dividend of $1.33 per share.
We currently expect our common stock cash dividend of $0.95 per share, totaling approximately $1.1 billion. In October 2017, we increased our quarterly common stock dividend to $1.05 per share, from an annualized amount of $3.80 per share to an annualized amount of $4.20 per share. As such, our board of directors declared a quarterly common stock cash dividend of $1.05 per share in October 2017, which represents an increase of 11% from the quarterly common stock cash dividend declared during the first three quarters of 2017. We currently expect our anticipated common stock cash dividends over the next 12 months to be a cumulative amount of at least $4.20 per share, or an aggregate amount of at least $1.7 billion. Over time, we expect to increase our dividend per share generally commensurate with our realized growth in cash flows. Any future dividends are subject to the approval of our board of directors.
Investing capital efficiently to grow long-term dividendsbe a cumulative amount of at least $5.32 per share,
Discretionary capital expenditures were $791.8 million, including wireless infrastructure improvements in order to support additional site rentals, construction of wireless infrastructure and land purchases.

See notes 3 and 12note 9 to our condensed consolidated financial statements.statements for further information regarding our common stock and dividends.
Outlook Highlights
The following are certain highlights of our full year 2017 and 20182021 outlook that impact our business fundamentals described above.
We expect that, when compared to full year 2020, our full year 2017 and 20182021 site rental revenue growth will be positively impacted by (1) a healthy environment for tenant additions, as large wireless carriers upgrade and enhance their networksfiber solutions tenants continue to meetfocus on meeting the increasing needdemand for wireless connectivity, (2)data.
We expect to continue to invest a contributionmeaningful amount of $885 to $905 million to site rental revenue during 2018 fromour available capital in the FiberNet Acquisition, the Wilcon Acquisition and the Lightower Acquisition, collectively (see notes 3 and 12 to our condensed consolidated financial statements), and (3) anticipated non-renewalsform of tenant leases primarily resulting from our customers' decommissioning of the Acquired Networks.

We expectdiscretionary capital expenditures for 20172021 based on the anticipated returns on such discretionary investments. We expect that our discretionary capital expenditures in 2021 will decrease when compared to 2020 as a result of both (1) the completion of certain fiber expansion projects in 2020 and 2018 to exceed levels from 2016(2) an expected higher proportion of small cell capital expenditures associated with a continued increase in the construction of new small cells. less capital-intensive tenant additions.
We also expect sustaining capital expenditures to beremain approximately 2% of net revenues for full year 20172021, consistent with historical annual levels.
Coronavirus (COVID-19)
In accordance with the U.S. Department of Homeland Security guidance issued in March 2020 designating telecommunications infrastructure and 2018.networks as critical infrastructure, we have continued our operations to ensure the viability of communications networks, which are essential to public health and safety. In response to the pandemic, we have taken a variety of measures to ensure the availability of our critical infrastructure, promote the health and safety of our employees, and support the communities in which we operate. These measures included requiring work-from-home arrangements for a large portion of our workforce, imposing travel restrictions for our employees where practicable, canceling physical participation in meetings, events and conferences, forming an internal committee to monitor and implement procedures for the return of our workforce to an office setting, and other modifications to our business practices. We have begun allowing employees based in certain offices to return to the office environment, on a voluntary basis, and currently intend to re-open our offices in the third quarter of 2021. We will continue to actively monitor the situation and may take further actions as may be required by governmental authorities, as advised by public health officials or that we determine are in the best interests of our employees, tenants, business partners and stockholders.

We do not believe that COVID-19 had a material impact on our financial position, results of operations and cash flows during the six months ended June 30, 2021. Given the Company’s access to various sources of liquidity and no near term debt maturities other than Commercial Paper Notes and principal payments on amortizing debt, we currently anticipate that we will be able to maintain sufficient liquidity as we manage through the current environment.

Liquidity and Capital Resources
Overview
General. Our core business generates revenues under long-term leasestenant contracts (see "Item 2. MD&A—General Overview—Overview") predominately from (1) the largest U.S. wireless carriers. Ourcarriers and (2) fiber solutions tenants. As a leading provider of shared communications infrastructure in the U.S., our strategy is to create long-term stockholder value via a combination of (1) growing cash flows generated from our portfolio of wirelesscommunications infrastructure, (2) returning a meaningful portion of our cash providedgenerated by operating activities to our stockholders in the form of dividends, and (3) investing capital efficiently to grow cash flows and long-term dividends per share. Our strategy is based, in part, on our belief that the U.S. is the most attractive market for shared communications infrastructure investment with the greatest long-term growth potential. We measure our efforts to create "long-term stockholder value" by the combined payment of dividends to stockholders and growth in our per share results.
We have engaged, and expect to continue to engage, in discretionary investments that we believe will maximize long-term stockholder value. Our historical discretionary investments include (in no particular order): purchasing our common stock,constructing communications infrastructure, acquiring or constructing wirelesscommunications infrastructure, acquiring land interests (which primarily relate to land assets under towers,towers), improving and structurally enhancing our existing wirelesscommunications infrastructure, purchasing shares of our common stock, and purchasing, repaying, or redeeming our debt. We have recently spent, and expect to continue to spend, a significant percentage of our discretionary investments on the construction of small cell networks.cells and fiber. We seek to fund our discretionary investments with both net cash providedgenerated by operating activities and cash available from financing capacity, such as the use of our undrawn availability from the 2016 Revolver, issuances under our CP Program, debt financings and issuances of equity or equity relatedequity-related securities, including under our 2021 ATM Program.
We seek to maintain a capital structure that we believe drives long-term stockholder value and optimizes our weighted-average cost of capital. We target a leverage ratio of approximately four to five times Adjusted EBITDA and interest coverage of Adjusted EBITDA to interest expense of approximately three times, Adjusted EBITDA, subject to various factors, such as the availability and cost of capital and the potential long-term return on our discretionary investments. We may choose to increase or decrease our leverage or coverage from these targets for various periods of time. We have no significant contractual debt maturities until 2023 (other than Commercial Paper Notes that may be outstanding from time to time and principal payments on certain outstanding debt).
We operate as a REIT for U.S. federal income tax purposes. We expect to continue to pay minimal cash income taxes as a result of our REIT status and our NOLs. See note 6 to our condensed consolidated financial statements and also our 20162020 Form 10-K.

Capital Expenditures
Our capital expenditures are categorized as discretionary, integration or sustaining as described below.
Discretionary capital expenditures are made with respect to activities which we believe exhibit sufficient potential to enhance long-term stockholder value. They primarily consist of improvementsexpansion or development of communications infrastructure (including capital expenditures related to existing wireless(1) enhancing communications infrastructure in order to add new tenants for the first time or support subsequent tenant equipment augmentations or (2) modifying the structure of a communications infrastructure asset to accommodate additional tenants) and construction of new wireless infrastructure, and, to a lesser extent,communications infrastructure. Discretionary capital expenditures also include purchases of land interests (which primarily relate to land assets under towers as we seek to manage our interests in the land beneath our towers. Improvementstowers), certain technology-related investments necessary to support and scale future customer demand for our communications infrastructure, and other capital projects. The expansion or development of existing wirelesscommunications infrastructure to accommodate new leasing typically varyvaries based on, among other factors: (1) the type of wirelesscommunications infrastructure, (2) the scope, volume, and mix of work performed on the wirelesscommunications infrastructure, (3) existing capacity prior to installation, or (4) changes in structural engineering regulations and standards. ConstructionCurrently, construction of new wirelesscommunications infrastructure is predominately comprised of the design and construction of small cells and fiber and small cells.(including certain construction projects that may take 18 to 36 months to complete). Our decisions regarding discretionary capital expenditures are influenced by the availability and cost of capital and expected returns on alternative uses of cash, such as payments of dividends and investments.
Sustaining capital expenditures consist of (1) corporatethose capital expenditures and (2)not otherwise categorized as discretionary capital improvementexpenditures, such as (1) maintenance capital expenditures on our wirelesscommunications infrastructure assets that enable our customers'tenants' ongoing quiet enjoyment of the wireless infrastructure.

Debt Covenants
The credit agreement governing the 2016Covenants. Our Credit FacilityAgreement contains financial maintenance covenants. We are currently in compliance with these financial maintenance covenants and, based upon our current expectations, we believe we will continue to comply with our financial maintenance covenants. In addition, certain of our debt agreements also contain restrictive covenants that place restrictions on us and may limit our ability to, among other things, incur additional debt and liens, purchase our securities, make capital expenditures, dispose of assets, undertake transactions with affiliates, make other investments, pay dividends or distribute excess cash flow. See our 2016the 2020 Form 10-K for a further discussion of our debt covenants, certain restrictive covenants and factors that are likely to determine our subsidiaries' ability to comply with current and future debt covenants.



Accounting and Reporting Matters
Critical Accounting Policies and Estimates
Our critical accounting policies and estimates are those that we believe (1) are most important to the portrayal of our financial condition and results of operations or (2) require our most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain. The critical accounting policies and estimates for 2017 are not intended to be a comprehensive list of our accounting policies and estimates. In many cases, the accounting treatment of a particular transaction is specifically prescribed by GAAP. In other cases, management is required to exercise judgment in the application of accounting principles with respect to particular transactions. The critical accounting policies and estimates for 2021 are not intended to be a comprehensive list of our accounting policies and estimates. Our critical accounting policies and estimates as of December 31, 20162020 are described in "Item 7. MD&A—Accounting and Reporting Matters" and in note 2 of our consolidated financial statements in our 2016the 2020 Form 10-K. The critical accounting policies and estimates for the first nine months of 2017 have not changed from the critical accounting policies for the year ended December 31, 2016.

Non-GAAP and Segment Financial Measures
We use earnings before interest, taxes, depreciation, amortization and accretion, as adjusted ("Adjusted EBITDA"), which is a non-GAAP financial measure, as an indicator of consolidated financial performance. Our measure of Adjusted EBITDA may not be comparable to similarly titled measures of other companies, including companies in the wirelesscommunications infrastructure sector or other REITs, and is not a measure of performance calculated in accordance with GAAP. Adjusted EBITDA should not be considered in isolation or as a substitute for operating income or loss,(loss), income (loss) from continuing operations, net income or loss,(loss), net cash provided by (used for) operating, investing and financing activities or other income statement or cash flow statement data prepared in accordance with GAAP and should be considered only as a supplement to net income or loss(loss) from continuing operations computed in accordance with GAAP as a measure of our performance. There are material limitations to using a measure such as Adjusted EBITDA, including the difficulty associated with comparing results among more than one company, including our competitors, and the inability to analyze certain significant items, including depreciation and interest expense, that directly affect our net income or loss. Management compensates for these limitations by considering the economic effect of the excluded expense items independently as well as in connection with their analysis of net income (loss). from continuing operations.
We define Adjusted EBITDA as net income (loss) from continuing operations plus restructuring charges (credits), asset write-down charges, acquisition and integration costs, depreciation, amortization and accretion, amortization of prepaid lease purchase price adjustments, interest expense and amortization of deferred financing costs, gains (losses)(gains) losses on retirement of long-term obligations, net gain (loss)(gain) loss on interest rate swaps, gains (losses)(gains) losses on foreign currency swaps, impairment of available-for-sale securities, interest income, other income (expense), benefit (provision)(income) expense, (benefit) provision for income taxes, cumulative effect of a change in accounting principle income (loss) from discontinued operations and stock-based compensation expense. The reconciliation of Adjusted EBITDA to our net income (loss) is set forth below andfrom continuing operations.

We believe Adjusted EBITDA is useful to investors or other interested parties in evaluating our financial performance because:
it is the primary measure used by our management (1) to evaluate the economic productivity of our operations and (2) for purposes of making decisions about allocating resources to, and assessing the performance of, our operations;
although specific definitions may vary, it is widely used by investors or other interested parties in evaluation of the wirelesscommunications infrastructure sector and other REITs to measure financial performance without regard to items such as depreciation, amortization and accretion, which can vary depending upon accounting methods and the book value of assets;
we believe it helps investors and other interested parties meaningfully evaluate and compare the results of our operations (1) from period to period and (2) to our competitors by removing the impact of our capital structure (primarily interest charges from our outstanding debt) and asset base (primarily depreciation, amortization and accretion) from our financial results; and
it is similar to the measure of current financial performance generally used in our debt covenant calculations.
Our management uses Adjusted EBITDA:
as a performance goal in employee annual incentive compensation;
as a measurement of financial performance because it assists us in comparing our financial performance on a consistent basis as it removes the impact of our capital structure (primarily interest charges from our outstanding debt) and asset base (primarily depreciation, amortization and accretion) from our operating results;

in presentations to our board of directors to enable it to have the same measurement of financial performance used by management;
for planning purposes, including preparation of our annual operating budget;
as a valuation measure in strategic analyses in connection with the purchase and sale of assets;
in determining self-imposed limits on our debt levels, including the evaluation of our leverage ratio and interest coverage ratio; and
with respect to compliance with our debt covenants, which require us to maintain certain financial ratios that incorporate concepts such as, or similar to, Adjusted EBITDA.
In addition to the non-GAAP measures used herein and as discussed in note 10 to our condensed consolidated financial statements, we also provide (1) segment site rental gross margin, (2) segment network services and other gross margin, and (3) segment operating profit, which are key measures used by management to evaluate the performance of our operating segments for purposes of making decisions about allocating capital and assessing performance.segments. These segment measures are provided pursuant to GAAP requirements related to segment reporting.
34


We define segment site rental gross margin as segment site rental revenues less segment site rental cost of operations, which excludes stock-based compensation expense and prepaid lease purchase price adjustments recorded in consolidated site rental cost of operations. We define segment network services and other gross margin as segment network services and other revenues less segment network services and other cost of operations, which excludes stock-based compensation expense recorded in consolidated network services and other cost of operations. We define segment operating profit as segment site rental gross margin plus segment network services and other gross margin, and segment other operating (income) expense, less selling, general and administrative expenses attributable to the respective segment. All of these measurements of profit or loss are exclusive of depreciation, amortization and accretion, which are shown separately. Additionally, certain costs are shared across segments and are reflected in our segment measures through allocations that management believes to be reasonable.

ITEM 3.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
ITEM 3.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
The following section updates "Item 7A. Quantitative and Qualitative Disclosures About Market Risk" in our 2016the 2020 Form 10-K and should be read in conjunction with that report as well as our condensed consolidated financial statements included in Part 1, Item 1 of this report.Form 10-Q.
Interest Rate Risk
Our interest rate risk as of June 30, 2021 relates primarily to the impact of interest rate movements on the following, after giving effect to the closingJuly 2021 repayment of the Lightower Acquisition:previously outstanding Tower Revenue Notes, Series 2015-1:
the potential refinancing of our existing debt ($15.920.0 billion outstanding at SeptemberJune 30, 20172021 and $12.2$19.4 billion at December 31, 2016)2020);
our $3.1$1.3 billion and $2.0$2.8 billion of floating rate debt at SeptemberJune 30, 20172021 and December 31, 2016,2020, respectively, which represented approximately 19%7% and 16%15% of our total debt, as of SeptemberJune 30, 20172021 and as of December 31, 2016,2020, respectively; and
potential future borrowings of incremental debt, including borrowings under our 2016 Credit Facility.Facility and issuances under the CP Program.
Over the next 12 months, we have no debt maturities other than principal payments on amortizing debt. We currently have no interest rate swaps.
Sensitivity Analysis
We manage our exposure to market interest rates on our existing debt by controlling the mix of fixed and floating rate debt. As of SeptemberJune 30, 2017, after giving effect to the closing of the Lightower Acquisition,2021, we had $3.1$1.3 billion of floating rate debt, none of which had LIBOR floors. As a result, a hypothetical unfavorable fluctuation in market interest rates on our existing debt of 1/8 of a percent point over a 12 month period would increase our interest expense by approximately $4$2 million.
Tabular Information
The following table provides information about our market risk related to changes in interest rates. The future principal payments and weighted-average interest rates are presented as of SeptemberJune 30, 2017,2021, after giving effect to the the closingJuly 2021 repayment of the Lightower Acquisition.previously outstanding Tower Revenue Notes, Series 2015-1. These debt maturities reflect contractualfinal maturity dates and do not consider the impact of the principal payments that commence if the applicable debt is not repaid or refinanced on or prior tofollowing the anticipated repayment dates on the Tower Revenue Notesof certain debt (see footnote (c) to the table below)footnotes (b) and (d)). The information presented below regarding the variable rate debt is supplementary to our sensitivity analysis regarding the impact of changes in the interest rates. See notes 4, 5 and 512 to our condensed consolidated financial statements and our 2016the 2020 Form 10-K for additional information regarding our debt.

(a)The fair value of our debt is based on indicative quotes (that is, non-binding quotes) from brokers that require judgment to interpret market information, including implied credit spreads for similar borrowings on recent trades or bid/ask offers. These fair values are not necessarily indicative of the amount which could be realized in a current market exchange.
(b)The average interest rate represents the weighted-average stated coupon rate (see footnotes (c) and (d)).
(c)
The impact of principal payments that will commence following the anticipated repayment dates is not considered. The Tower Revenue Notes have a principal amount of $2.3 billion, $300 million, and $700 million, with anticipated repayment dates in 2020, 2022 and 2025, respectively.
(d)
If the Tower Revenue Notes are not repaid in full by the applicable anticipated repayment dates, the applicable interest rate increases by approximately 5% per annum and monthly principal payments commence using the Excess Cash Flow (as defined in the indenture governing the applicable Tower Revenue Notes) of the issuers of the Tower Revenue Notes. The Tower Revenue Notes are presented based on their contractual maturity dates ranging from 2040 to 2045 and include the impact of an assumed 5% increase in interest rate that would occur following the anticipated repayment dates but exclude the impact of monthly principal payments that would commence using Excess Cash Flow of the issuers of the Tower Revenue Notes. The full year 2016 Excess Cash Flow of the issuers of the Tower Revenue Notes was approximately $563.8 million. We currently expect to refinance these notes on or prior to the respective anticipated repayment dates.
(e)Predominantly consists of our 2016 Term Loan A and 2016 Revolver borrowings, each of which mature in 2022.

See the disclosure in note 8 to our condensed consolidated financial statements set forth in Part I, Item 1 of this Quarterly Report on Form 10-Q, which disclosure is hereby incorporated herein by reference.10-Q.


ITEM 1A.RISK FACTORS
You should carefully considerITEM 1A.RISK FACTORS
There are no material changes to the risk factors below, as well as the other information containeddiscussed in this document and"Item 1A. Risk Factors" in our 20162020 Form 10-K. Based on recent activities, including the Lightower Acquisition, we have added the following risk factors.
We may fail to realize all of the anticipated benefits of the Lightower Acquisition or those benefits may take longer to realize than expected. We may also encounter significant difficulties in integrating Lightower’s business.
Our ability to realize the anticipated benefits of the Lightower Acquisition will depend, to a large extent, on our ability to integrate the Lightower business into ours. The integration of an independent business into our business is a complex, costly and time-consuming process. As a result, we will be required to devote significant management attention and resources to integrate Lightower’s business practices and operations with ours, including a larger fiber solutions business than we currently manage. The integration process may disrupt the businesses and, if implemented ineffectively, would restrict the realization of the full expected benefits. The failure to meet the challenges involved in integrating Lightower’s business and to realize the anticipated benefits of the transaction could cause an interruption of, or a loss of momentum in, the activities of the Company after the acquisition and could adversely affect our results of operations. In addition, we could also encounter additional transaction-related costs or other factors, which could cause dilution or decrease or delay the expected benefits of the Lightower Acquisition and cause a decrease in the market price of our common stock.
Finally, if the Lightower Acquisition does not provide the level of contribution we currently anticipate, our expectation of future dividends, including dividend growth, on our common stock would be negatively impacted.
If we fail to pay scheduled dividends on the 6.875% Mandatory Convertible Preferred Stock, in cash, common stock, or any combination of cash and common stock, we will be prohibited from paying dividends on our common stock, which may jeopardize our status as a REIT.
The terms of the 6.875% Mandatory Convertible Preferred Stock provide that, unless accumulated dividends have been paid or set aside for payment on all outstanding 6.875% Mandatory Convertible Preferred Stock for all past dividend periods, no dividends may be declared or paid on our common stock. If that were to occur, the inability to pay dividends on our common stock might jeopardize our status as a REIT for U.S. federal income tax purposes. See note 9 to our condensed consolidated financial statements.
