2.Restatement of Previously Issued Condensed Consolidated Financial Statements
Recent Accounting Pronouncements Not Yet Adopted
In May 2014,The following tables summarize the FASB released updated guidance regardingimpact of the recognitionrestatement adjustments that were related to the timing of revenue from contracts with customers, exclusiverecognition on its tower installation services. Specifically, the Company determined that its historical practice of those contracts within lease accounting. The core principlerecognizing the full transaction price as service revenues upon completion of the guidance is that an entity should recognize revenue to depict the transferinstallation was not acceptable under GAAP. Instead, a portion 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 for the Company's tower installation services, specifically the amounts associated with permanent improvements recorded as fixed assets, represent a lease component and should be recognized as site rental revenues on a ratable basis over the associated estimated lease term. In addition, the Company has also made other adjustments 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 decisionfinancial statements referenced above to defer the effective date of the standard by one year.   This guidance is requiredcorrect errors that were not material 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 does not expect the guidance to have a material impact on its condensed consolidated financial statements. Such immaterial adjustments are related to a revision in the presentation of certain tower installation activities from a gross basis to a net basis, including the associated removal of certain amounts historically categorized as capital expenditures.  These immaterial adjustments relate exclusively to the Company's Towers segment. Collectively, the restatement adjustments and other immaterial adjustments are referred to herein as "Historical Adjustments."
In February 2016,addition to the FASB issued new guidance 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 valuerestatement 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 forcondensed consolidated financial statements, certain historical information in the Company as of January 1, 2019 and is requirednotes 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 expectcondensed consolidated financial statements have been restated 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 assessreflect the impact of the standard; (2) expects this guidance to have a material impact on its condensed consolidated balance sheet due to the addition of right-of-use assets and lease liabilities for all lessee arrangements with a term greater than 12 months; and (3) continues to assess additional impacts to its condensed consolidated financial statements, including the condensed consolidated statement of operations and the condensed consolidated statement of cash flows.Historical Adjustments.
In February 2017, 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 for the Company 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.

3.Acquisitions
FiberNet Acquisition
On November 1, 2016, the Company announced that it had entered into a definitive agreement to acquire FPL FiberNet Holdings, LLC and certain other subsidiaries of NextEra Energy, Inc. (collectively, "FiberNet") for approximately $1.5 billion in cash, subject to certain limited adjustments ("FiberNet Acquisition"). FiberNet is a fiber services provider in Florida and Texas that, as of the agreement date, owned or had rights to approximately 11,500 route miles of fiber installed or under construction, inclusive of approximately 6,000 route miles in top metro markets.

(c)For tax purposes, the Fibernet Acquisition was treated as a purchase of assets. As a result of the tax step-up and the expectation that the vast majority of the assets will be included in the Company's REIT, no deferred taxes were recorded in connection with the FiberNet Acquisition.
Net revenues attributable to the FiberNet Acquisition are included in the Company's consolidated statements of operations and comprehensive income (loss) since the date the acquisition was completed. For the nine months ended September 30, 2017, the FiberNet Acquisition contributed $109.0 million to consolidated net revenues.
Wilcon Acquisition
On April 17, 2017, the Company announced that it had entered into a definitive agreement to acquire Wilcon Holdings LLC ("Wilcon") from Pamlico Holdings and other unit holders of Wilcon for approximately $600 million in cash, subject to certain limited adjustments ("Wilcon Acquisition"). Wilcon is a fiber services provider that owns approximately 1,900 route miles of fiber, primarily in Los Angeles and San Diego. On June 26, 2017, the Company closed the Wilcon Acquisition, which was financed using proceeds from the May 2017 Equity Financing (as defined in note 9) and the 4.75% Senior Notes (as defined in note 4).
The preliminary purchase price of approximately $600 million was primarily comprised of other intangible assets (predominantly comprised of site rental contracts and customer relationships) of approximately $140 million, property and equipment of approximately $150 million, goodwill of approximately $360 million, offset by deferred revenues of approximately $40 million.
The preliminary purchase price allocation for the Wilcon Acquisition resulted in the recognition of goodwill based on (1) the Company's expectation to leverage the Wilcon fiber footprint to support new small cell networks and fiber based solutions, (2) the complementary nature of the Wilcon fiber to the Company's existing fiber assets and its location primarily in Los Angeles and San Diego, where the Company expects to see wireless carrier network investments, (3) the Company's belief that the acquired fiber assets are well positioned to benefit from the continued growth trends in the wireless industry, and (4) other intangibles not qualified for separate recognition, including the assembled workforce. The preliminary purchase price allocation for the Wilcon Acquisition is based upon a preliminary valuation which is subject to change as the Company obtains additional information with respect to fixed assets, intangible assets and certain liabilities.
Lightower Acquisition
On July 18, 2017, the Company announced that it has entered into a definitive agreement to acquire LTS Group Holdings LLC ("Lightower") from Berkshire Partners, Pamlico Capital and other investors for approximately $7.1 billion in cash, subject to certain limited adjustments ("Lightower Acquisition"). Lightower owns or has rights to approximately 32,000 route miles of fiber located primarily in top metro markets in the Northeast, including Boston, New York and Philadelphia. On November 1, 2017, the Company closed the Lightower Acquisition, which was financed using (1) cash on hand, including proceeds from the July 2017 Equity Financings and August 2017 Senior Notes Offering, and (2) borrowings under the 2016 Revolver. Due to the proximity of the closing of the Lightower Acquisition to the 10-Q filing date, the Company was not able to determine the preliminary purchase price allocation or provide pro forma financial information as of the date of this report. See note 12.

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 $123 million included in "Other current assets" and non-current amounts of $1.4 billion included in "Deferred site rental receivables" as of March 31, 2020. 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 Company's condensed consolidated balance sheet.
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 tenant. The revenue recognized is based on an allocation of the 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 component and (2) the performance of the service. Amounts under the Company's tower installation service agreements that represent a 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 recognized as services and other revenues. Since performance obligations are typically satisfied prior to receiving payment from tenants, the unconditional right to payment is

6.7.Income Taxes
The Company operates as a REIT for U.S. federal income tax purposes. As a REIT, the Company is generally entitled to a deduction for dividends that it pays and therefore is not subject to U.S. federal corporate income tax on its net taxable income that is currently distributed to its stockholders. 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 in 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.

While there are uncertainties inherent in the ultimate outcome of such matters and it is impossible to presently determine the ultimate costs or losses that may be incurred, if any, management believes the resolution of such uncertainties and the incurrence of such costs should not have a material adverse effect on the Company's condensed consolidated financial position or results of operations. Additionally, the Company and certain of its subsidiaries are contingently liable for commitments or performance guarantees arising in the ordinary course of business, including certain letters of credit or surety bonds.

Shareholder Litigation
In February and March 2020, putative securities class action suits were filed in the United States District Court for the District of New Jersey against the Company and certain of its current officers. The lawsuits were filed on behalf of investors that purchased or otherwise acquired stock of the Company between February 26, 2018 and February 26, 2020. The allegations relate to allegedly false or misleading statements or other failures to disclose information about the Company's business, operations and prospects. The complaints seek unspecified money damages and the award of plaintiffs' costs and expenses incurred in the respective class action. The Company is currently unable to determine the likelihood of an outcome or estimate a range of reasonably possible losses, if any, with respect to these lawsuits. The Company believes these lawsuits are without merit and intends to defend itself vigorously.
In April 2020, a stockholder derivative lawsuit was filed by Melvyn Klein in the United States District Court for the District of Delaware, against the Company, as a nominal defendant, and its current directors and certain of its current officers. The complaint alleges, among other things, breaches of fiduciary duties, waste of corporate assets, unjust enrichment, and false or misleading statements, between February 27, 2018 through the present. The complaint seeks, among other things, unspecified money damages, costs and expenses, restitution from the defendants, and an order requiring the Company to implement certain corporate governance reforms.

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%92% of our thirdfirst quarter 20172020 consolidated net revenues. Our Towers operating segment and Small Cells operatingFiber segment accounted for 81%66% and 19%34%, respectively, of our thirdfirst quarter 20172020 site rental revenues, respectively.revenues. See note 1011 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 existing communications infrastructure. We are focused on maximizing the recurring site rental cash flows generated from providing our tenants with long-term access to our shared infrastructure 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 tenants to expand coverage and capacity in order to meet increasing demand for 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 wireless tenants' growing network needs through our shared communications infrastructure model, which is an efficient and cost-effective way to serve our tenants. Additionally, we believe our ability to share our fiber assets across multiple tenants to deploy both small cells and offer fiber solutions allows us to generate cash flows and increase stockholder return.
Return cash generated by operating activities to common stockholders in the form of dividends. We believe that distributing a meaningful portion of our cash generated by operating activities appropriately provides common stockholders with increased certainty for a portion of expected long-term stockholder value while still allowing 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. In addition to adding tenants to existing communications infrastructure, we seek to invest our available capital, including the net cash generated 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);
improvements and structural enhancements to our existing communications infrastructure;
Grow cash flows from our wireless infrastructure. We seek to maximize our site rental cash flows by working with our customers to provide them quick access to our wireless infrastructure and entering into associated long-term leases. Tenant additions or modifications of existing tenant equipment (collectively, "tenant additions") enable our customers to expand coverage and capacity in order to meet increasing demand for wireless connectivity, 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' growing connectivity needs through our shared wireless infrastructure model, which is an efficient and cost effective way to serve our customers. We also believe that there will be considerable future demand for our wireless infrastructure based on the location of our wireless infrastructure and the rapid growth in wireless connectivity, which will lead to future growth in the wireless industry.
Return cash provided by operating activities to stockholders in the form of dividends. We believe that distributing a meaningful portion of our cash provided by operating activities appropriately provides stockholders with increased certainty for a portion of expected long-term stockholder value while still retaining 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 stockholders.
Invest capital efficiently to grow cash flows and long-term dividends per share. We seek to invest our available capital, including the net cash provided by our operating activities and external financing sources, in a manner that will increase long-term stockholder value on a risk-adjusted basis. Our historical investments have included the following (in no particular order):

purchases of shares of our common stock from time to time; and
acquisitions or construction of towers, fiber and small cells;
acquisitions of land interests under towers;
improvements and structural enhancements to our existing wireless infrastructure; or
purchases, repayments or redemptions of our debt.

Our strategy to create long-term stockholder value is based on our belief that additionalthere will be considerable future demand for our wirelesscommunications infrastructure will be created bybased on the expected continuedlocation of our assets and the rapid growth in the demand for wireless connectivity.data. 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.
Business Fundamentals and Results
The following are certain highlights of our business fundamentals and results as of and for the ninethree months ended September 30, 2017.March 31, 2020.
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 qualifyremain qualified and be taxed as a REIT, we will generally be required to annually distribute to our stockholders 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 67 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 and connectivity
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.
We expect existing and potential new customertenant demand for our wirelesscommunications infrastructure will result from (1) new technologies, (2) increased usage of wireless applications (including mobile entertainment, mobile internet, usage, and machine-to-machine applications),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, or (6) the adoption of other bandwidth-intensive applications (such as cloud services and video communications) and (7) the availability of additional spectrum.
We expect U.S. wireless carriers will continue to focus on improving network quality and expanding capacity (including through 5G initiatives) by utilizing a combination of towers and small cells. We believe our product offerings of towers and small cells provide a comprehensive solution to our wireless tenants' growing communications infrastructure needs.
We expect organizations will continue to increase the usage of high-bandwidth applications that will require the utilization of more fiber infrastructure and fiber solutions, such as those we provide.
Within our Fiber segment, we are able to generate growth and returns for our stockholders by deploying our fiber for both small cells and fiber solutions tenants.
Tenant additions on our existing communications infrastructure are achieved at a low incremental operating cost, delivering high incremental returns.

Net cash provided by operating activities was $653 million for the three months ended March 31, 2020.
In addition to the positive impact of contractual escalators, we expect to grow our core business of providing access to our wirelesscommunications infrastructure as a result of future anticipated additional demand for our wirelesscommunications infrastructure.
Returning cash flows provided by operations to stockholders in the form of dividends
During each of the first three quarters of 2017,March 2020, we paid a common stock cash dividend of $0.95$1.20 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. $513 million.
We currently expect our anticipated common stock cash dividends over the next 12 months to be a cumulative amount of at least $4.20$4.80 per share, or an aggregate amount of at least $1.7approximately $2.0 billion.
Over time, we expect to increase our dividend per share generally commensurate with our realized growth in cash flows. Any future common stock dividends are subject to the approval ofdeclaration by our board of directors.

Lightower Acquisition
In July 2017, we entered into a definitive agreement to acquire Lightower for approximately $7.1 billion in cash, subject to certain limited adjustments. On November 1, 2017, we closed the Lightower Acquisition, which was financed using (1) cash on hand, including the proceeds from the July 2017 Equity Offerings and August 2017 Senior Notes Offering, and (2) borrowings under the 2016 Revolver. Lightower owns or has rights to approximately 32,000 route miles of fiber located primarily in top metro markets in the Northeast, including Boston, New York and Philadelphia. See notes 3 and 12 to our condensed consolidated financial statements.
Outlook Highlights
The following are certain highlights of our full year 2017 and 20182020 outlook that impact our business fundamentals described above.
We expect that, when compared to full year 2019, our full year 2017 and 20182020 site rental revenue growth will be positively impacted by (1) a healthy environment forhigher tenant additions, as large wireless carriers upgrade and enhance their networksfiber solutions tenants attempt to meet the increasing needdemand for wireless connectivity, (2) a contribution of $885 to $905 million to site rental revenue during 2018 from 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-renewals of tenant leases primarily resulting from our customers' decommissioning of the Acquired Networks.

We also expect sustaining capital expenditures to beremain approximately 2% of net revenues for full year 20172020.

Coronavirus (COVID-19)
The global outbreak of the novel coronavirus (COVID-19) was declared a pandemic by the World Health Organization and 2018.a national emergency by the U.S. government in March 2020 and has adversely affected the United States. In response, both the public and private sectors have introduced certain policies and initiatives in an effort to reduce the transmission of COVID-19 ("Initiatives"), such as the imposition of travel restrictions; mandates from federal, state and local authorities to close non-essential businesses and avoid large gatherings of people; quarantine or "shelter-in-place;" and the promotion of social distancing and the adoption of work-from-home and online learning by companies and institutions. In addition, the continued spread of COVID-19 and the resulting Initiatives have led to a significant economic downturn, global supply chain disruptions and volatility in the global capital markets.

In accordance with the U.S. Department of Homeland Security guidance issued in March 2020 designating telecommunications infrastructure and networks as critical infrastructure, we have continued our operations to ensure viability of communications networks, which are essential to public health and safety. To date, 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 include providing support for our tenants as reflected in the FCC's "Keep Americans Connected" pledge, requiring work-from-home arrangements for a large portion of our workforce and imposing travel restrictions for our employees where practicable, canceling physical participation in meetings, events and conferences, and other modifications to our business practices. 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, 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 in the first quarter of 2020. Given the Company’s access to various sources of liquidity, we currently anticipate that we will be able to maintain sufficient liquidity as we manage through the current environment. See also "Item 2. MD&A—Liquidity and Capital Resources—Liquidity Position" and "Item 1A. Risk Factors."

Interest expense and amortization of deferred financing costs were $154.1$175 million for the thirdfirst quarter of 20172020 and increased by $24.2$7 million, or 4%, from $129.9$168 million during the same period in the prior year. The increase predominately resulted from a corresponding increase in our outstanding indebtedness due to acquisitions, including the FiberNet Acquisition, the Wilcon Acquisition and the Lightower Acquisition. See notes 3 and 12 to our condensed consolidated financial statements. As a result of repaying certainfinancing of our debt, in conjunction with our refinancing activities, we incurred a loss of $10.3 million for the third quarter of 2016. See our 2016 Form 10-K for further discussion of our first quarter 2016 refinancing activities.discretionary capital expenditures.
For the thirdfirst quarter of 20172020 and 2016,2019, the effective tax rate differs from the federal statutory rate predominately due to our REIT status, including the dividends paid deduction.  See note 67 to our condensed consolidated financial statements and also note 11 to our consolidated financial statements in our 2016the 2019 Form 10-K.
Net income (loss) attributable to CCIC stockholders was income of $115.2$185 million during the thirdfirst quarter of 20172020 compared to income of $98.4$193 million during the thirdfirst quarter of 2016.2019. The increase was predominately related to net growth in both our Towers and Small Cells segments as well as a decrease in the losses on retirement of long-term obligations, partially offset by an increase in expenses, including (1) interest expense and amortization of deferred financing costs, (2) depreciation, amortization, and accretion, and (3) general and administrative expenses.

Site rental revenues grew $202.6 million, or 8%, from the nine months ended September 30, 2016 to the nine months ended September 30, 2017. This growth was predominately comprised of the factors depicted in the chart below:
ytdsrrwaterfalla17.jpg    
(a)Includes (1) amortization of up front payments received from long-term tenant contracts and other deferred credits (commonly referred to as prepaid rent) and (2) the construction of small cells.
(b)Represents initial contribution of acquisitions and tower builds until the one-year anniversary of the acquisition or build.
Towers site rental revenues for the first nine months of 2017 were $2.2 billion and increased by $40.8 million, or 2%, from the same period in the prior year. The increase in Towers site rental revenues was impacted by the following items, inclusive of straight-line accounting, in no particular order: tenant additions across our entire portfolio, renewals or extensions of tenant leases, escalations, acquisitions (including the TDC Acquisition in April 2016), and non-renewals of tenant leases predominately arising from our customers' decommissioning of the Acquired Networks. Tenant additions were influenced by our customers' ongoing efforts to improve network quality and capacity.
Small Cells site rental revenues for the first nine months of 2017 were $459.5 million and increased by $161.7 million, or 54%, from $297.8 million during the same period in the prior year. The increase in Small Cells site rental revenue was predominately impacted by (1) an increase of $106.7 million from the FiberNet Acquisition completed in January 2017, (2) an increase of $13.3 million from the Wilcon Acquisition completed in June 2017 and (3) the leasing of newly constructed small cells. Demand for small cells was influenced by our customers' growing adoption of small cells as an important component of their network strategy to provide capacity and relieve network congestion.
The increase in Towers site rental gross margin was related to the previously mentioned 2% increase in Towers site rental revenues and relatively fixed costs to operate our towers. The increase in Small Cells site rental gross margin was predominately related to the previously mentioned 54%impact from the aforementioned Towers service activity as well as an increase in Small Cells site rental revenues.
Towers network services and other gross margin was $185.0 million for the first nine months of 2017 and remained consistent with the same period in the prior year. Towers network service and other gross margin can fluctuate based on (1) the volume of activity from carrier network enhancements and (2) the volume and mix of network services and other work. Our network services and other offerings are of a variable nature as these revenues are not under long-term contracts.

General and administrative expenses for the first nine months of 2017 were $299.2 million and increased by $20.3 million, or approximately 7%, from $278.9 million during the same period in the prior year. The increase inselling, general and administrative expenses, was primarily related to the growth in our Small Cells business as a result of activities such as (1) the FiberNet Acquisition, (2) the Wilcon Acquisition and (3) the continued expansion of our Small Cells segment.
Towers operating profit for the first nine months of 2017 increasedpartially offset by $32.9 million, or 2%, from the same period in the prior year. Towers operating profit was positively impacted by the growth in our site rental activities in both our Towers and relatively fixed costs to operate our towers.
Small Cells operating profit for the first nine months of 2017 increased by $102.8 million, or 68%, from the same period in the prior year. Small Cells operating profit was positively impacted by the previously mentioned FiberNet Acquisition, Wilcon Acquisition and the leasing of newly constructed small cells.Fiber segments.
Adjusted EBITDA increased $121.8$10 million, or 7%1%, from the first nine monthsquarter of 20162019 to the first nine monthsquarter of 2017. Adjusted EBITDA was positively impacted by2020, reflecting the growth in our site rental activities in both Towers and Small Cells, including the TDC Acquisition, the FiberNet Acquisition and the Wilcon Acquisition.
Depreciation, amortization and accretion was $880.2 million for the first nine months of 2017 and increased by $45.5 million, or 5%, from $834.7 million during the same period in the prior year. This increase predominately resulted from a corresponding increase in our gross property and equipment due to capital expenditures and acquisitions, including the FiberNet Acquisition and Wilcon Acquisition.
Interest expense and amortization of deferred financing costs were $430.4 million for the first nine months of 2017 and increased $44.7 million, or 12%, from $385.7 million during the first nine months of 2016. The increase predominately resulted from a corresponding increase in our outstanding indebtedness due to acquisitions, including the FiberNet Acquisition, the Wilcon Acquisition and the Lightower Acquisition. As a result of repaying certain of our debt, in conjunction with our refinancing activities, we incurred losses of $3.5 million and $52.3 million for the first nine months of 2017 and 2016, respectively. See note 4 to our condensed consolidated financial statements.
For the first nine months of 2017 and 2016, the effective tax rate differs from the federal statutory rate predominately due to our REIT status, including the dividends paid deduction.  See note 6 to our condensed consolidated financial statements and also note 11 to our consolidated financial statements in our 2016 Form 10-K.
Net income (loss) attributable to CCIC stockholders was income of $346.4 million compared to income of $232.3 million during the first nine months of 2016. The increase was predominately due to growth in both our Towers and Small CellsFiber segments,as well as a decrease in the losses on retirement of long-term obligations, partially offset by an increasethe previously-mentioned decrease in expenses, including (1) interest expense and amortization of deferred financing costs, (2) depreciation, amortization, and accretion, and (3) general and administrative expenses.Towers service activity.



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 2018 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 2021 (other than 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 67 to our condensed consolidated financial statements and our 2016the 2019 Form 10-K.

The following is a summary of our capitalization and liquidity position as of September 30, 2017,March 31, 2020, after giving effect to our April 2020 Senior Notes offering and the closingapplication of the Lightower Acquisition.net proceeds therefrom.

Operating Activities
Net cash provided by operating activities from continuing operationsof $653 million for the first ninethree months of 20172020 increased $112.6by $141 million, or 9%28%, compared to the first ninethree months of 2016,2019, due primarily to the growth in our core business and a net benefitincrease from other changes in working capital. Changes in working capital contribute to variability in net cash provided by operating activities, largely due to the timing of advanced payments by us and advanced receipts from tenants. We expect to grow our net cash provided by operating activities in the future (exclusive of movementschanges in working capital) if we realize expected growth in our core business.
Investing Activities
Net cash used for investing activities of $468 million for the first ninethree months of 2017 increased $1.8 billion2020 decreased by $21 million, or 4%, from the first ninethree months of 20162019 as a result of a decrease in discretionary capital expenditures related to the FiberNet Acquisitionconstruction of small cells and the Wilcon Acquisition (see note 3 to our condensed consolidated financial statements for further discussion).

Capital Expenditures
Our capital expenditures arehave been categorized as discretionary, sustaining or sustaining,integration 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 consist of improvements to existing wireless infrastructure, construction of new wireless infrastructure, and, to a lesser extent, purchases of land assets under towers as we seek to manage our interests in the land beneath our towers. Improvements to existing wireless infrastructure to accommodate new leasing typically vary based on, among other factors: (1) the type of wireless infrastructure, (2) the scope, volume, and mix of work performed on the wireless infrastructure, (3) existing capacity prior to installation, or (4) changes in structural engineering regulations and standards. Construction of new wireless infrastructure is predominately comprised of the design and construction of fiber and small cells.
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 expansion or development of communications infrastructure (including capital expenditures related to (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 communications infrastructure. Discretionary capital expenditures also include purchases of land interests (which primarily relates to land assets under towers as we seek to manage our interests in the land beneath our towers), 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 communications infrastructure to accommodate new leasing typically varies based on, among other factors: (1) the type of communications infrastructure, (2) the scope, volume, and mix of work performed on the communications infrastructure, (3) existing capacity prior to installation, or (4) changes in structural engineering regulations and standards. Currently, construction of new communications infrastructure is predominately comprised of the construction of small cells and fiber. 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.
Integration capital expenditures consist of those capital expenditures made as a result of integrating acquired companies into our business.
Sustaining capital expenditures consist of (1) corporatethose capital expenditures and (2)not otherwise categorized as discretionary or integration 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.communications infrastructure and (2) ordinary corporate capital expenditures.

(b)Towers segment includes $42 million and $41 million of capital expenditures incurred during the three months ended March 31, 2020 and 2019, respectively, in connection with tenant installations and upgrades on our towers.
Discretionary capital expenditures were primarily impacted by the construction of small cell networkscells and lower amounts of improvementsfiber (including certain construction projects that may take 18 to existing towers.36 months to complete) to address our tenants' growing demand for data. See also "Item 2. MD&A—General Overview—Outlook Highlights" for our expectations surrounding 2017 and 20182020 capital expenditures.
Financing Activities
Activities. We seek to allocate cash generated by our operations in a manner that will enhance long-term stockholder value, which may include various financing activities such as (in no particular order): (1) paying dividends on our common stock (currently expected to total at least $4.80 per share over the next 12 months, at least $4.20 per share, or an aggregate amount of at least $1.7 billion, subject to future approval by our board of directors),approximately $2.0 billion); (2) paying dividends on our 6.875% Mandatory Convertible Preferred Stock (expected to total overapproximately $28 million, prior to the next 12 months approximately $113 million),automatic conversion of such preferred stock in August 2020); (3) purchasing our common stock,stock; or (4) purchasing, repaying, or redeeming our debt.

Sales, if any, under the 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 sales under the ATM Program for general corporate purposes, which may include the funding of future acquisitions or investments and the repayment or repurchase of any outstanding indebtedness. During the nine months ended September 30, 2017, 0.2 million shares of common stock were sold under the ATM Program generating net proceeds of $22.0 million. As of November 2, 2017, we had approximately $150 million of gross sales of common stock availability remaining on our ATM Program. See note 910 to our condensed consolidated financial statements.statements for further information regarding our 2018 ATM Program.
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 2019 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 2020 are not intended to be a comprehensive list of our accounting policies and estimates. Our critical accounting policies and estimates as of December 31, 20162019 are described in "Item 7. MD&A—Accounting and Reporting Matters" and in note 23 of our consolidated financial statements in our 2016the 2019 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), 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) 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).

We define Adjusted EBITDA as net income (loss) 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)(income) loss from discontinued operations and stock-based compensation expense. The reconciliation of Adjusted EBITDA to our net income (loss) is set forth below and excludes items in the Company's Adjusted EBITDA definition which are not applicable to the periods shown.

(b)The above reconciliation excludes the items included in our Adjusted EBITDA definition which are not applicable to the periods shown.
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 wireless 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.
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;

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;

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

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 1011 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.
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, 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
The following section updates "Item 7A. Quantitative and Qualitative Disclosures About Market Risk" in our 2016the 2019 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.Quarterly Report on Form 10-Q.
Interest Rate Risk
Our interest rate risk relates primarily to the impact of interest rate movements on the following, after giving effect to our April 2020 Senior Notes offering and the closingapplication of the Lightower Acquisition:net proceeds therefrom:
the potential refinancing of our existing debt ($15.918.7 billion outstanding at September 30, 2017March 31, 2020 and $12.2$18.1 billion at December 31, 2016)2019);
our $3.1$2.3 billion and $2.0$3.0 billion of floating rate debt at September 30, 2017March 31, 2020 and December 31, 2016,2019, respectively, which represented approximately 19%12% and 16%17% of our total debt, as of September 30, 2017March 31, 2020 and as of December 31, 2016,2019, 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 September 30, 2017,March 31, 2020, after giving effect to our April 2020 Senior Notes offering and the closingapplication of the Lightower Acquisition,net proceeds therefrom, we had $3.1$2.3 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$3 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 September 30, 2017,March 31, 2020, after giving effect to our April 2020 Senior Notes offering and the the closingapplication of the Lightower Acquisition.net proceeds therefrom. 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 45 and 56 to our condensed consolidated financial statements and our 2016the 2019 Form 10-K for additional information regarding our debt.

ITEM 4.CONTROLS AND PROCEDURES
Disclosure Controls and Procedures
The Company conducted an evaluation, under the supervision and with the participation of the Company's management, including the Company's Chief Executive Officer and Chief Financial Officer, of the effectiveness of the Company's disclosure controls and procedures as of the end of the period covered by this report. Based on this evaluation, the Chief Executive Officer and Chief Financial Officer concluded that due to the material weakness in the Company's internal control over financial reporting described below, the Company's disclosure controls and procedures were not effective in alerting them in a timely manner to material information relating to the Company required to be included in the Company's periodic reports under the Securities Exchange Act of 1934, as amended.
Material Weakness in Internal Control over Financial Reporting
As previously disclosed in the Company's 2019 Form 10-K, management concluded that a material weakness existed in the Company's internal control over financial reporting, as it did not effectively design and maintain controls related to the accounting for tower installation services.
Remediation of Material Weakness
Management has created a plan of remediation to strengthen its internal control over financial reporting. The remediation efforts include 1) revising its accounting policies for its tower installation services to identify and account for lease components and the related calculation of deferred revenue, and 2) making improvements to existing processes and controls related to the determination of the accuracy of capital expenditures made for permanent improvements associated with tower installation services. Management is implementing training with respect to the new processes and evaluating the need for additional resources.
Management believes that the measures described above will remediate the identified material weakness and strengthen the Company’s internal control over financial reporting. Management has begun to take these actions to remediate the material weakness and may take additional measures to strengthen its internal control environment.
Changes in Internal Control Over Financial Reporting
There have been no changes in the Company's internal control over financial reporting during the fiscal quarter covered by this report that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.


PART II—OTHER INFORMATION


ITEM 1.LEGAL PROCEEDINGS
See the disclosure in note 89 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 considerThe following risk factor is provided to update the risk factors below,previously discussed in "Item 1A. Risk Factors" in the 2019 Form 10-K.
The impact of COVID-19 and related risks could materially affect our financial position, results of operations and cash flows.
The global spread of COVID-19 has created significant uncertainty and economic disruption. We have modified, and might further modify, our business practices as a result of the COVID-19 pandemic, the economic and social ramifications of the disease, and the societal and governmental responses in the communities in which we operate. See "Item 2. MD&A—General Overview—Coronavirus (COVID-19)" for further information. The extent to which the COVID-19 pandemic will affect our financial position, results of operations and cash flows is difficult to predict with certainty and depends on numerous evolving factors, including: the duration and scope of the pandemic; government, social, business and other actions that have been and will be taken in response to the pandemic; and the effect of the pandemic on short- and long-term general economic conditions. Among other things, COVID-19 and the Initiatives could (1) adversely affect the ability of our suppliers and vendors to provide products and services

to us; (2) result in decreased demand for our communications infrastructure; (3) make it more difficult for us to serve our tenants, including as a result of delays or suspensions in the issuance of permits or other authorizations needed to conduct our business; and (4) increase our cost of capital and adversely impact our access to capital. The potential effects of COVID-19 could also heighten the risks disclosed in many of our risk factors that are included in "Item 1A. Risk Factors" in the 2019 Form 10-K. Due to the speed with which the situation is developing and factors beyond our knowledge or control, including the duration and severity of COVID-19, as well as third-party actions taken to contain its spread and mitigate its public health effects, at this time we cannot estimate or predict with certainty the other information containedimpact of COVID-19, the Initiatives, or the measures we take in this document and our 2016 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,response thereto 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 ourfinancial position, results of operations. In addition, weoperations and cash flows, particularly over the near to medium term, but the impact 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.be material.
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.
