General Overview
Overview
We own, operate and lease shared communications infrastructure. See "Item 1.
Business" for a further discussion of our business, including our long-term
strategy, our REIT status, certain key terms of our tenant contracts and growth
trends in the demand for data. Site rental revenues represented 88% of our 2019
consolidated net revenues. The vast majority of our site rental revenues is of a
recurring nature and has been contracted for in a prior year. See "Explanatory
Note" immediately preceding Item 1 of this Annual Report on Form 10-K and note 2
to our consolidated financial statements for further information on the
restatement of previously issued financial statements.
Business Fundamentals and Results
The following are certain highlights of our business fundamentals and results:
•       We operate as a REIT for U.S. federal income tax purposes (see "Item 1.

Business-Company Developments, REIT Status and Industry Overview-REIT

Status" and note 11 to our consolidated financial statements).

• Potential growth resulting from the 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) 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.


•             Substantially all of our communications infrastructure can
              accommodate additional tenancy, either as currently

constructed or


              with appropriate modifications.


•       Returning cash flows provided by operations to stockholders in the form

of dividends (see also "Item 1. Business-Strategy")

• During 2019, we paid common stock dividends totaling approximately

$1.9 billion. See "Item 7. MD&A-General Overview-Common Stock
           Dividend" for a discussion of the increase to our quarterly dividend
           in the fourth quarter of 2019.

• Investing capital efficiently to grow long-term dividends per share




•             Discretionary capital expenditures of $1.9 billion, 

predominately


              resulting from the construction of new communications
              infrastructure and improvements to existing communications
              infrastructure in order to support additional tenants.


•             We expect to continue to construct and acquire new

communications


              infrastructure based on our tenants' needs and generate attractive
              long-term returns by adding additional tenants over time.

• Site rental revenues under long-term tenant contracts

• Initial terms of five to 15 years for site rental revenues derived


           from wireless tenants, with contractual escalations and multiple
           renewal periods of five to 10 years each, exercisable at the 

option of


           the tenant.


• Initial terms that generally vary between three to 20 years for site


           rental revenues derived from our fiber solutions tenants 

(including


           from organizations with high-bandwidth and multi-location

demands).


•          Weighted-average remaining term of approximately five years, exclusive

           of renewals exercisable at the tenants' option, currently

representing


           approximately $24 billion of expected future cash inflows.

• Majority of our revenues from large wireless carriers




•          Approximately 75% of our site rental revenues were derived from
           T-Mobile, AT&T, Verizon Wireless and Sprint. See also "Item 1A. Risk
           Factors" and note 16 to our consolidated financial statements for a
           further discussion of our largest customers.



                                       27

--------------------------------------------------------------------------------

• Majority of land interests under our towers under long-term control




•          Approximately 90% of our Towers site rental gross margin and
           approximately 80% of our Towers site rental gross margin is derived
           from towers that reside on land that we own or control for greater
           than 10 and 20 years, respectively. The aforementioned

percentages


           include towers that reside on land interests that are owned, 

including


           through fee interests and perpetual easements, which represent
           approximately 40% of our Towers site rental gross margin.

• Majority of our fiber assets are located in major metropolitan areas and

are on public rights-of-way.

• Minimal sustaining capital expenditure requirements

• Sustaining capital expenditures represented approximately 2% of net revenues.

• Debt portfolio with long-dated maturities extended over multiple years,

with the vast majority of such debt having a fixed rate (see "Item 7A.

Quantitative and Qualitative Disclosures About Market Risk" for a further


        discussion of our debt)


•       During 2019, we completed several debt transactions to refinance and

extend the maturities of certain of our debt. See "Item 7. MD&A-Liquidity

and Capital Resources-Financing Activities" for further discussion of our

debt transactions.

• As of December 31, 2019, our outstanding debt has a weighted average


           interest rate of 3.8% and weighted average maturity of 

approximately


           six years (assuming anticipated repayment dates where 

applicable).

• 83% of our debt has fixed rate coupons.




•          Our debt service coverage and leverage ratios are comfortably within
           their respective financial maintenance covenants. See "Item 7.
           MD&A-Liquidity and Capital Resources-Debt Covenants" for a further
           discussion of our debt covenants.

• Significant cash flows from operations

• Net cash provided by operating activities was $2.7 billion.




•          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.


Common Stock Dividend
In the aggregate, we paid approximately $1.9 billion in common stock dividends
in 2019. During each of the first three quarters of 2019, we paid a quarterly
common stock dividend of $1.125 per share, totaling approximately $1.4 billion.
In October 2019, our board of directors declared a quarterly common stock cash
dividend of $1.20 per share, which represents an increase of approximately 7%
from the quarterly common stock dividend declared during each of the first three
quarters of 2019. We currently expect our common stock dividends over the next
12 months to be a cumulative amount of at least $4.80 per share, or an aggregate
amount of approximately $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 declaration by our board
of directors. See notes 12 and 19 to our consolidated financial statements.
Outlook Highlights
The following are certain highlights of our 2020 outlook that impact our
business fundamentals described above.
•       We expect that, when compared to full year 2019, our full year 2020 site

rental revenue growth will be positively impacted by higher tenant

additions, as large wireless carriers and fiber solutions tenants attempt

to meet the increasing demand for data. See note 5 to our consolidated


        financial statements.


•       We expect discretionary capital expenditures for 2020 to remain
        relatively consistent with 2019 levels as we continue to construct new
        small cells and fiber as a result of the anticipated returns on such

discretionary investments. We also expect sustaining capital expenditures


        of approximately 2% of net revenues for full year 2020.

--------------------------------------------------------------------------------

2019 and 2018
Total site rental revenues for 2019 grew by $297 million, or 6%, from 2018. This
increase was predominately comprised of the factors depicted in the chart below:
(In millions of dollars)
[[Image Removed: chart-cb7a1cf51dcf5100b7b.jpg]]

(a) As restated.

(b) Includes amortization of upfront payments received from long-term tenants and

other deferred credits (commonly referred to as prepaid rent).

(c) The components in this chart may not sum to the total due to rounding.




Towers site rental revenues for 2019 were approximately $3.4 billion and
increased by $193 million, or 6%, from approximately $3.2 billion during 2018.
The increase in Towers site rental revenues was impacted by the following items,
inclusive of straight-line accounting: tenant additions across our entire
portfolio, renewals or extensions of tenant contracts, escalations and
non-renewals of tenants contracts. Tenant additions were influenced by our
tenants' ongoing efforts to improve network quality and capacity.
Fiber site rental revenues for 2019 were $1.7 billion and increased by $104
million, or 7%, from $1.6 billion from 2018. The increase in Fiber site rental
revenues was predominately impacted by the increased demand for small cells and
fiber solutions. Increased demand for small cells was driven by our tenants'
network strategy in an effort to provide capacity and relieve network
congestion, and increased demand for fiber solutions was driven by increasing
demand for data.
The increase in Towers site rental gross margin from 2018 to 2019 was related to
the previously-mentioned 6% increase in Towers site rental revenues and
relatively fixed costs to operate our towers. The increase in Fiber site rental
gross margins was predominately related to the previously-mentioned 7% increase
in Fiber site rental revenues.
Selling, general and administrative expenses for 2019 were $614 million and
increased by $51 million, or 9%, from $563 million during 2018. The increase in
selling, general and administrative expenses was primarily related to the growth
in our business.
Towers operating profit for 2019 increased by $195 million, or 8%, from 2018.
The increase in Towers operating profit was primarily related to the growth in
our Towers site rental revenues and relatively fixed costs to operate our
towers.
Fiber operating profit for 2019 increased by $55 million, or 6%, from 2018.
Fiber operating profit was positively impacted by increased demand for small
cells and fiber solutions and was partially offset by an increase in
Fiber-related selling, general and administrative expenses.

                                       30
--------------------------------------------------------------------------------

Depreciation, amortization and accretion was approximately $1.6 billion for 2019
and increased by $45 million, or 3%, from 2018. This increase predominately
resulted from a corresponding increase in our gross property and equipment due
to capital expenditures.
Interest expense and amortization of deferred financing costs were $683 million
for 2019 and increased by $41 million, or 6%, from $642 million during 2018. The
increase predominately resulted from a corresponding increase in our outstanding
indebtedness due to the financing of our discretionary capital expenditures.
As a result of repaying certain of our indebtedness in conjunction with our
refinancing activities, we incurred losses on retirement of long-term
obligations of $2 million and $106 million for the years ended 2019 and 2018,
respectively. See note 9 to our consolidated financial statements.
The provisions for income taxes for 2019 and 2018 were $21 million and $19
million, respectively. For both 2019 and 2018, the effective tax rate differs
from the federal statutory rate predominately due to our REIT status, including
the dividends paid deduction. See "Item 1. Business--Company Developments, REIT
Status and Industry Overview-REIT Status," "Item 7. MD&A-Accounting and
Reporting Matters-Critical Accounting Policies and Estimates" and note 11 to our
consolidated financial statements.
Net income (loss) attributable to CCIC common stockholders was income of $747
million during 2019 compared to income of $509 million during 2018. The increase
was predominately related to net growth in both our Towers and Fiber segments
and a decrease in losses on retirement of long-term obligations, partially
offset by an increase in expenses, including (1) selling, general and
administrative expenses, (2) depreciation, amortization and accretion and (3)
interest expense and amortization of deferred financing costs.
Adjusted EBITDA increased $208 million, or 7%, from 2018 to 2019, reflecting the
growth in our site rental activities in both Towers and Fiber segments.
2018 and 2017
Total site rental revenues for 2018 grew by $1.1 billion, or 28%, from 2017.
This increase was predominately comprised of the factors depicted in the chart
below:
(In millions of dollars)
[[Image Removed: chart-b04a5eda38dd52d0a37.jpg]]

(a) As restated.

(b) Includes amortization of upfront payments received from long-term tenants and

other deferred credits (commonly referred to as prepaid rent).

(c) Represents the contribution from recent acquisitions until the one-year

anniversary of the acquisition.

(d) The components in this chart may not sum to the total due to rounding.


                                       31
--------------------------------------------------------------------------------

Towers site rental revenues for 2018 were approximately $3.2 billion and
increased by $231 million, or 8%, from approximately $3.0 billion during 2017.
The increase in Towers site rental revenues was impacted by the following items,
inclusive of straight-line accounting: tenant additions across our entire
portfolio, renewals or extensions of tenant contracts, escalations and
non-renewals of tenant contracts. Tenant additions were influenced by our
tenants' ongoing efforts to improve network quality and capacity.
Fiber site rental revenues for 2018 were $1.6 billion and increased by $831
million, or 108%, from $769 million in 2017. The increase in Fiber site rental
revenues was predominately impacted by the 2017 Acquisitions and the increased
demand for small cells and fiber solutions. Increased demand for small cells was
driven by our tenants' network strategy in an effort to provide capacity and
relieve network congestion, and increased demand for fiber solutions was driven
by increasing demand for data.
The increase in Towers site rental gross margin from 2017 to 2018 was related to
the previously-mentioned 8% increase in Towers site rental revenues and
relatively fixed costs to operate our towers. The increase in Fiber site rental
gross margins was predominately related to the previously-mentioned 108%
increase in Fiber site rental revenues.
Selling, general and administrative expenses for 2018 were $563 million and
increased by $137 million, or 32%, from $426 million during 2017. The increase
in selling, general and administrative expenses was primarily related to the
growth in our Fiber business, including the Lightower Acquisition and Wilcon
Acquisition.
Towers operating profit for 2018 increased by $237 million, or 11%, from 2017.
The increase in Towers operating profit was primarily related to the growth in
our Towers site rental revenues and relatively fixed costs to operate our
towers.
Fiber operating profit for 2018 increased by $476 million, or 112%, from 2017
and was positively impacted by the previously-mentioned Lightower Acquisition
and Wilcon Acquisition and the increased demand for small cells and fiber
solutions described above.
Depreciation, amortization and accretion was approximately $1.5 billion for 2018
and increased by $286 million, or 23%, from approximately $1.2 billion during
2017. This increase predominately resulted from a corresponding increase in our
gross property and equipment due to capital expenditures and acquisitions,
including the Lightower Acquisition and Wilcon Acquisition discussed above.
Interest expense and amortization of deferred financing costs were $642 million
for 2018 and increased by $51 million, or 9%, from $591 million during 2017.
This increase predominately resulted from the full year impact of 2017 financing
activities used to partially fund our 2017 Acquisitions and the financing of our
discretionary capital expenditures. See notes 4 and 9 to our consolidated
financial statements.
As a result of repaying certain of our indebtedness in conjunction with our
refinancing activities, we incurred losses on retirement of long-term
obligations of $106 million and $4 million for 2018 and 2017, respectively. For
a further discussion of the debt refinancings, see note 9 to our consolidated
financial statements, "Item 7. MD&A-Liquidity and Capital Resources" and "Item
7A. Quantitative and Qualitative Disclosures About Market Risk."
The provisions for income taxes for 2018 and 2017 were $19 million and $26
million, respectively. For both 2018 and 2017, the effective tax rate differs
from the federal statutory rate predominately due to our REIT status, including
the dividends paid deduction. In addition to our REIT status, in 2017 the
effective rate differs from the federal statutory rate due to a non-cash tax
provision of $15 million as a result of the enactment of the Tax Reform Act. See
"Item 1. Business--Company Developments, REIT Status and Industry Overview-REIT
Status," "Item 7. MD&A-Accounting and Reporting Matters-Critical Accounting
Policies and Estimates" and note 11 to our consolidated financial statements.
Net income (loss) attributable to CCIC common stockholders for 2018 was income
of $509 million compared to income of $308 million during 2017. The increase was
predominately related to net growth in both our Towers and Fiber segments,
partially offset by an increase in expenses, including (1) depreciation,
amortization and accretion, (2) selling, general and administrative expenses,
(3) losses on the retirement of long-term obligations, and (4) interest expense
and amortization of deferred financing costs.
Adjusted EBITDA increased by $689 million, or 29%, from 2017 to 2018 reflecting
the growth in our site rental activities in both Towers and Fiber, including the
Lightower Acquisition and the Wilcon Acquisition discussed above.

Liquidity and Capital Resources
Overview
General. Our core business generates revenues under long-term tenant contracts
(see "Item 1. Business-Overview" and "Item 7. MD&A-General Overview-Overview")
from (1) the largest U.S. wireless carriers 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 communications
infrastructure, (2) returning a meaningful portion of our cash generated 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. See "Item 1. Business-Strategy" for a further
discussion of our strategy.
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): constructing
communications infrastructure, acquiring communications infrastructure,
acquiring land interests (which primarily relate to land assets under towers),
improving and structurally enhancing our existing communications 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 cells
and fiber. We seek to fund our discretionary investments with both net cash
generated 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-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 five times Adjusted EBITDA and interest
coverage of Adjusted EBITDA to interest expense of approximately three times,
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.

       pursuant to our 2018 ATM Program. Our liquidity uses over the next 12
       months are expected to include (1) debt service obligations of $100
       million (principal payments), (2) cumulative common stock dividend

payments expected to be at least $4.80 per share, or an aggregate amount

payments related to such preferred stock of approximately $57 million and (4)
capital expenditures. Additionally, amounts available under the CP Program may
be repaid and re-issued from time to time. During the next 12 months, while our
liquidity uses are expected to exceed our net cash provided by operating
activities, we expect that our liquidity sources described above should be
sufficient to cover our expected uses. Historically, from time to time, we have
accessed the capital markets to issue debt and equity.
•      We have no scheduled contractual debt maturities other than principal

payments on amortizing debt. See "Item 7A. Quantitative and Qualitative


       Disclosures About Market Risk" for a tabular presentation of our debt

Operating Activities. The increase in net cash provided by operating activities
of $198 million for 2019 from 2018 was due primarily to growth in our core
business offset by a net decrease from changes in working capital. The increase
in net cash provided by operating activities of $468 million for 2018 from 2017
was due primarily to growth in our core business, including as a result of the
Lightower Acquisition and Wilcon Acquisition, offset by a net decrease from
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
changes in working capital) if we realize expected growth in our core business.
Investing Activities. Net cash used for investing activities
for 2019 increased $288 million from 2018 primarily as a result of increased
discretionary capital expenditures due to the construction of small cells and
fiber.
Our capital expenditures have been categorized as discretionary, sustaining or
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 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 those capital expenditures not

otherwise categorized as discretionary or integration capital

expenditures, such as (1) maintenance capital expenditures on our

communications infrastructure assets that enable our tenants' ongoing

quiet enjoyment of the communications infrastructure and (2) ordinary


       corporate capital expenditures.



                                       34

--------------------------------------------------------------------------------

A summary of our capital expenditures for the last three years is as follows (in millions of dollars):


                     [[Image Removed: finalcapextable.jpg]]

(a) Includes $208 million, $128 million, and $124 million of capital expenditures

incurred during the years ended December 31, 2019, 2018, and 2017,

respectively, in connection with customer installations and upgrades on our

towers.

(b) Prior to January 1, 2018, integration capital expenditures were included

within sustaining capital expenditures.

(c) As restated.




Capital expenditures increased from 2018 to 2019 and were primarily impacted by
the construction of small cells and fiber (including certain construction
projects that may take 18 to 36 months to complete) to address our tenants'
growing demand for data. Our sustaining capital expenditures were approximately
2% of net revenues in 2019, consistent with historical annual levels. See
"Item 7. MD&A-General Overview-Outlook Highlights" for a discussion of our
expectations surrounding 2020 capital expenditures.
Acquisitions. See notes 4 and 7 to our consolidated financial statements for a
discussion of our acquisitions during the year ended December 31, 2017.
Financing 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) paying dividends on our
common stock (currently expected to total at least $4.80 per share over the next
12 months, or an aggregate amount of approximately $2.0 billion), paying
dividends on our 6.875% Convertible Preferred Stock (expected to total
approximately $57 million, prior to the automatic conversion of such preferred
stock in August 2020), purchasing our common stock, or purchasing, repaying, or
redeeming our

                                       35
--------------------------------------------------------------------------------

debt. See "Item 7. MD&A-Liquidity and Capital Resources-Overview," "Item 7. MD&A-General Overview-Common Stock Dividend" and notes 9 and 12 to our consolidated financial statements. In 2019, our financing activities predominately related to the following: • paying an aggregate of $1.9 billion in dividends on our common stock;

• paying an aggregate of $113 million in dividends on our 6.875% Convertible

Preferred Stock;

• issuing $1.0 billion aggregate principal amount of senior unsecured notes

in February 2019, the proceeds of which we used to repay a portion of the

borrowings under the 2016 Revolver;

• establishing a CP Program in April 2019 pursuant to which we may issue

short-term, unsecured commercial paper notes. Notes under the CP Program

may be issued, repaid and re-issued from time to time, with an aggregate


       principal amount of Commercial Paper Notes outstanding under the CP
       Program at any time not to exceed $1.0 billion. The net proceeds of the
       Commercial Paper Notes are expected to be used for general corporate
       purposes;

• entering into an amendment to the 2016 Credit Facility in June 2019 to (1)

increase our commitments under the 2016 Revolver by $750 million for total

commitments of $5.0 billion and (2) extend the maturity of the 2016 Credit

Facility from June 2023 to June 2024; and

• issuing $900 million aggregate principal amount of senior unsecured notes

in August 2019, the proceeds of which we used to repay outstanding

borrowings under the 2016 Revolver and CP Program.

In 2018, our financing activities predominately related to the following: • paying an aggregate of $1.8 billion in dividends on our common stock;

• paying an aggregate of $113 million in dividends on our 6.875% Convertible

Preferred Stock;

• issuing $1.75 billion aggregate principal amount of senior unsecured notes


       in January 2018, the proceeds of which we used to repay (1) in full the
       Senior Secured Tower Revenue Notes, Series 2010-3, Class C-2020 and pay

related fees and expenses and (2) a portion of the outstanding borrowings

under the 2016 Revolver;

• completing an offering of 8 million shares of our common stock ("March


       2018 Equity Financing"), the proceeds of which we used for general
       corporate purposes as well as repayment of outstanding indebtedness;

• terminating the previously outstanding "at-the-market" stock offering

program through which we had the right to issue and sell shares of our

common stock having an aggregate gross sales price of up to $500

million to or through sales agents ("2015 ATM Program") in March 2018, and

in April 2018, establishing the 2018 ATM Program through which we may

issue and sell shares of our common stock having an aggregate gross sales

price of up to $750 million;

• entering into an amendment to the 2016 Credit Facility in June 2018 to (1)

increase our commitments under the 2016 Revolver by $750 million for total


       commitments of $4.25 billion and (2) extend the maturity of the 2016
       Credit Facility from August 2022 to June 2023; and

• issuing $1.0 billion aggregate principal amount of senior secured tower

revenue notes in July 2018, the proceeds of which we used, together with

cash on hand, to repay, in full, the Senior Secured Tower Revenue Notes,

Series 2010-6, Class C-2020 and pay related fees and expenses.

(a) The following items are in addition to the obligations disclosed in the above

table:

• We have a legal obligation to perform certain asset retirement activities,

including requirements upon lease and easement terminations to remove

communications infrastructure or remediate the land upon which our

communications infrastructure resides. The cash obligations disclosed in


       the above table, as of December 31, 2019, are exclusive of estimated
       undiscounted future cash outlays for asset retirement obligations of
       approximately $1.0 billion. As of December 31, 2019, the net present value

of these asset retirement obligations was approximately $227 million. See

note 8 to our consolidated financial statements.

• We are contractually obligated to pay or reimburse others for property

taxes related to certain of our communications infrastructure.

• We have the option to purchase approximately 53% of our towers that are

leased or subleased or operated and managed under master leases, subleases

and other agreements with AT&T, Sprint and T-Mobile at the end of their

respective lease terms. We have no obligation to exercise such purchase

options. See note 1 to our consolidated financial statements.

• We have legal obligations for open purchase order commitments obtained in

the ordinary course of business that have not yet been fulfilled.

(b) The impact of principal payments that will commence following the anticipated

repayment dates of our Tower Revenue Notes is not considered. The Tower

Revenue Notes have principal amounts of $300 million, $250 million, $700

million and $750 million, with anticipated repayment dates in 2022, 2023,

2025 and 2028, respectively. See note 9 to our consolidated financial

statements for our definition of and additional information regarding the

Tower Revenue Notes.

(c) 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

2042 to 2048 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 (as defined in the indenture governing the applicable Tower Revenue

Notes) of the issuers of the Tower Revenue Notes. The full year 2019 Excess

Cash Flow (as defined in the indenture governing the applicable Tower Revenue

Notes) of the issuers of the Tower Revenue Notes was approximately $764

million. We currently expect to refinance these notes on or prior to the

respective anticipated repayment dates.

(d) Interest payments on the floating rate debt are based on estimated rates

currently in effect.

(e) Amounts relate primarily to lease obligations for the land interests on which

our towers reside and are based on the assumption that payments will be made

for certain renewal periods exercisable at our option that are reasonably

certain to be exercised and excludes our contingent payments for operating

leases (such as payments based on revenues derived from the communications

infrastructure located on the leased asset) as such arrangements are excluded

from our operating lease liability. See note 15 to our consolidated financial

statements for further discussion of our operating lease obligations. See

also the table below summarizing remaining terms to expiration.

(f) Amounts relate primarily to access agreement obligations for rights-of-way,

franchises, pole attachments and other agreements to operate our fiber assets

and are based on the assumption that payments will be made for certain

renewal periods exercisable at our option that are reasonably certain to be

exercised and excludes our contingent payments for access agreements.

(g) Predominantly consists of outstanding indebtedness under our CP Program. Such


    amounts may be issued, repaid, or re-issued from time to time.

The following chart summarizes our rights to the land interests under our
towers, including renewal terms exercisable at our option, as of December 31,
2019. As of December 31, 2019, the leases for land interests under our towers
had an average remaining life of approximately 35 years, weighted based on
Towers site rental gross margin. See "Item 1A. Risk Factors" for a discussion of
retaining land interests under our towers.

Debt Covenants
Our Credit Agreement 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 note 9 to our consolidated financial statements for further discussion
of our debt covenants. See also "Item 1A. Risk Factors" for a discussion of
compliance with our debt covenants. The following are ratios applicable to the
financial maintenance covenants under the Credit Agreement as of December 31,
2019.

Off-balance Sheet Arrangements
We have no off-balance sheet arrangements as defined in Item 303(a)(4)(ii) of
Regulation S-K.

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. 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 2019 are not intended to be a comprehensive list of
our accounting policies and estimates. See note 3 to our consolidated financial
statements for a summary of our significant accounting policies, including
information related to our adoption of the new lease accounting guidance
(commonly referred to as "ASC 842" or "new lease standard") on January 1, 2019.
Lease Accounting - Lessee. For our Towers segment, our lessee arrangements
primarily consist of ground leases for land under our towers. Ground leases for
land are specific to each site and are generally for an initial term of five to
10 years and are renewable (and cancelable after a notice period) at our option.
We also enter into term easements and ground leases in which we prepay the
entire term. For our Fiber segment, our lessee arrangements primarily include
leases of fiber assets to facilitate our small cells and fiber solutions. The
majority of our lease agreements have certain termination rights that provide
for cancellation after a notice period and multiple renewal options exercisable
at our option. We include certain renewal option periods in the lease term when
we determine that the options are reasonably certain to be exercised.
For both our Towers and Fiber segments, operating lease expense is recognized on
a ratable basis, regardless of whether the payment terms require us to make
payments annually, quarterly, monthly, or for the entire term in advance.
Certain of our ground lease and fiber lease agreements contain fixed escalation
clauses (such as fixed dollar or fixed percentage increases) or inflation-based
escalation clauses (such as those tied to the change in consumer price index
("CPI")). If the payment terms include fixed escalator provisions, the effect of
such increases is recognized on a straight-line basis. We calculate the
straight-line expense over the contract's estimated lease term, including any
renewal option periods that we deem reasonably certain to be exercised.
In conjunction with the adoption of ASC 842, we recognized a right-of-use
("ROU") asset and lease liability for each of our operating leases. ROU assets
represent our right to use an underlying asset for the estimated lease term, and
lease liabilities represent the present value of our future lease payments. In
assessing our leases and determining our lease liability at lease commencement
or upon modification, we are not able to readily determine the rate implicit for
our lessee arrangements and thus use our incremental borrowing rate on a
collateralized basis to determine the present value of our lease payments. Our
ROU assets are measured as the balance of the lease liability plus any prepaid
or accrued lease payments and any unamortized initial direct costs.
We review the carrying value of our ROU assets for impairment, similar to our
other long-lived assets, whenever events or changes in circumstances indicate
that the carrying amounts may not be recoverable. We could record impairments in
the future if there are changes in (1) long-term market conditions, (2) expected
future operating results or (3) the utility of the assets that negatively impact
the fair value of our ROU assets.
Revenue Recognition. 88% of our total revenue for 2019 consists of site rental
revenues, which are recognized on a ratable basis over the fixed, non-cancelable
term of the relevant tenant contract, generally ranging from five to 15 years
for site rental revenues derived from wireless tenants and three to 20 years for
site rental revenues derived from fiber solutions tenants, regardless of whether
the payments from the tenant are received in equal monthly amounts during the
life of a tenant contract. Certain of our 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 change in 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 tenant contract. When calculating our
straight-line rental revenues, we consider all fixed elements of tenant
contractual escalation provisions, even if such escalation provisions contain a
variable element (such as an escalator tied to an inflation-based index) in
addition to a minimum. To the extent we acquire below-market tenant leases for
contractual interests with tenants on the acquired communications infrastructure
(for example with respect to small cells and fiber), we record the fair value as
deferred credits and amortize such deferred credits to site rental revenues over
their estimated lease term. Since we recognize revenue on a straight-line basis,
a portion of the site rental revenues in a given period represents cash
collected or contractually collectible in other periods. Our assets related to
straight-line site rental revenues are included in "Other current assets" and
"Deferred site rental

                                       39

receivables." Amounts billed or received prior to being earned are deferred and
reflected in "Deferred revenues" and "Other long-term liabilities." Amounts to
which we have an unconditional right to payment, which are related to both
satisfied or partially satisfied performance obligations, are recorded within
"Receivables, net" on the consolidated balance sheet.
As part of our effort to provide comprehensive communications infrastructure
solutions, as an ancillary business, we also offer certain services primarily
relating to our Towers segment, which represent 12% of our total revenues for
2019. Services and other revenue consists predominately of (1) site development
services primarily relating to existing or new tenant equipment installations,
including: site acquisition, architectural and engineering, or zoning and
permitting (collectively, "site development services") and (2) tenant equipment
installation or subsequent augmentations (collectively, "installation
services"). Upon contract commencement, we assess our services to tenants and
identify performance obligations for each promise to provide a distinct service.
We 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 we believe we have 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 transaction price for tower installation services consists of amounts for
(1) permanent improvements to our towers that represent a lease component and
(2) the performance of the service. Amounts under our tower installation
services agreements that represent a lease component are recognized as site
rental revenues on a ratable basis over the length of the associated estimated
lease term. For the performance of the tower installation service, we have one
performance obligation, which is satisfied at the time of the applicable
installation or augmentation and recognized as services and other revenues. See
"Explanatory Note" immediately preceding Item 1 of this Annual Report on Form
10-K and note 2 to our consolidated financial statements for further information
regarding the impact of the Restatement Adjustments.
Since performance obligations are typically satisfied prior to receiving payment
from tenants, the unconditional right to payment is recorded within
"Receivables, net" on our consolidated balance sheet.
The vast majority of our services revenues relates to our Towers segment and
generally have a duration of one year or less. See note 3 to our consolidated
financial statements.
Accounting for Acquisitions - General. As described in "Item 1. Business," the
majority of our communications infrastructure has been acquired directly or
indirectly from the four largest wireless carriers (or their predecessors)
through transactions consummated since 1999. We evaluate each of our
acquisitions to determine if it should be accounted for as a business
combination or as an acquisition of assets. For our business combinations, we
allocate the purchase price to the assets acquired and liabilities assumed based
on their estimated fair value at the date of acquisition. Any purchase price in
excess of the net fair value of the assets acquired and liabilities assumed is
allocated to goodwill. See "Item 7. MD&A-Accounting and Reporting
Matters-Accounting for Acquisitions-Valuation" below and note 3 to our
consolidated financial statements.
The determination of the final purchase price allocation could extend over
several quarters resulting in the use of preliminary estimates that are subject
to adjustment until finalized. Such changes could have a significant impact on
our consolidated financial statements.
Accounting for Acquisitions - Leases. With respect to business combinations that
include towers that we lease and operate, such as the AT&T, T-Mobile and Sprint
leased and subleased towers, we evaluate such agreements to determine treatment
as finance or operating leases. The evaluation of such agreements for finance or
operating lease treatment previously included consideration of each of the lease
classification criteria under ASC 840-10-25, namely (1) the transfer of
ownership provisions, (2) the existence of bargain purchase options, (3) the
length of the remaining lease term, and (4) the present value of the minimum
lease payments. With respect to the AT&T Acquisition, T-Mobile Acquisition, and
the Sprint towers acquired in the Global Signal Acquisition, we determined that
the tower leases were finance leases and the underlying land leases were
operating leases based upon the lease term criterion, after considering the
fragmentation criteria applicable under ASC 840-10-25 to leases involving both
land and buildings (i.e., towers). We determined that the fragmentation criteria
was met, and the tower leases could be accounted for as finance leases apart
from the land leases, which are accounted for as operating leases, since (1) the
fair value of the land in the aforementioned business combinations was greater
than 25% of the total fair value of the leased property at inception and (2) the
tower lease expirations occur beyond 75% of the estimated economic life of the
tower assets.
Since the adoption of ASC 842 in 2019, the Company has not consummated any
material acquisitions. See note 3 to our consolidated financial statements for
further information.

                                       40
--------------------------------------------------------------------------------

Accounting for Acquisitions - Valuation. As of December 31, 2019, our largest
asset was property and equipment, which primarily consists of communications
infrastructure, followed by goodwill, operating lease ROU assets and intangible
assets. Our identifiable intangible assets predominately relate to the site
rental contracts and tenant relationships intangible assets. See note 3 to our
consolidated financial statements for further information regarding the nature
and composition of the site rental contracts and tenant relationships intangible
assets.
The fair value of the vast majority of our assets and liabilities is determined
by using either:
(1)     discounted cash flow valuation methods (for estimating identifiable

intangibles such as site rental contracts and tenant relationships or

operating lease right-of-use assets and lease liabilities acquired); or




(2)     estimates of replacement costs (for tangible fixed assets such as
        communications infrastructure).


The purchase price allocation requires subjective estimates that, if incorrectly
estimated, could be material to our consolidated financial statements, including
the amount of depreciation, amortization and accretion expense. The most
important estimates for measurement of tangible fixed assets are (1) the cost to
replace the asset with a new asset and (2) the economic useful life after giving
effect to age, quality, and condition. The most important estimates for
measurement of intangible assets are (1) discount rates and (2) timing and
amount of cash flows including estimates regarding tenant renewals and
cancellations. The most important estimates for measurement of operating lease
ROU assets and lease liabilities acquired are (1) present value of our future
lease payments, including whether renewals or extensions should be measured, and
(2) favorability or unfavorability to the current market terms. With respect to
business combinations that include towers that we lease and operate, such as the
T-Mobile, Sprint and AT&T leased and subleased towers, we evaluate such
agreements to determine treatment as finance or operating leases and
identification of any bargain purchase options.
We record the fair value of obligations to perform certain asset retirement
activities, including requirements, pursuant to our ground leases, easements,
and leased facility agreements to remove communications infrastructure or
remediate the space upon which certain of our communications infrastructure
resides. In determining the fair value of these asset retirement obligations we
must make several subjective and highly judgmental estimates such as those
related to: (1) timing of cash flows; (2) future costs; (3) discount rates; and
(4) the probability of enforcement to remove the towers or small cells or
remediate the land. See note 3 to our consolidated financial statements.
Accounting for Long-Lived Assets - Useful Lives. We are required to make
subjective assessments as to the useful lives of our tangible and intangible
assets for purposes of determining depreciation, amortization and accretion
expense that, if incorrectly estimated, could be material to our consolidated
financial statements. Depreciation expense for our property and equipment is
computed using the straight-line method over the estimated useful lives of our
various classes of tangible assets. The substantial portion of our property and
equipment represents the cost of our communications infrastructure, which is
generally depreciated with an estimated useful life equal to the shorter of
(1) 20 years or (2) the term of the lease (including optional renewals) for the
land interests under the communications infrastructure.
The useful life of our intangible assets is estimated based on the period over
which the intangible asset is expected to benefit us and gives consideration to
the expected useful life of other assets to which the useful life may relate. We
review the expected useful lives of our intangible assets on an ongoing basis
and adjust if necessary. Amortization expense for intangible assets is computed
using the straight-line method over the estimated useful life of each of the
intangible assets. The useful life of the site rental contracts and tenant
relationships intangible assets is limited by the maximum depreciable life of
the communications infrastructure (20 years), as a result of the interdependency
of the communications infrastructure and site rental contracts and tenant
relationships. In contrast, the site rental contracts and tenant relationships
are estimated to provide economic benefits for several decades because of the
low rate of tenant cancellations and high rate of renewals experienced to date.
Thus, while site rental contracts and tenant relationships are valued based upon
the fair value of the site rental contracts and tenant relationships which
includes assumptions regarding both (1) tenants' exercise of optional renewals
contained in the acquired leases and (2) renewals of the acquired leases past
the contractual term including exercisable options, the site rental contracts
are amortized over a period not to exceed 20 years as a result of the useful
life being limited by the depreciable life of the communications infrastructure.
Accounting for Long-Lived Assets - Impairment Evaluation. We review the carrying
values of property and equipment, intangible assets, or other long-lived assets
for impairment whenever events or changes in circumstances indicate that the
carrying amounts may not be recoverable. We utilize the following dual grouping
policy for purposes of determining the unit of account for testing impairment of
the site rental contracts and tenant relationships:
(1)     we pool site rental contracts and tenant relationships intangible assets
        and property and equipment into portfolio groups; and



                                       41

--------------------------------------------------------------------------------

(2) we separately pool site rental contracts and tenant relationships by

significant tenant or by tenant grouping for individually insignificant

tenants, as appropriate.




We first pool site rental contracts and tenant relationships intangible assets
and property and equipment into portfolio groups for purposes of determining the
unit of account for impairment testing, because we view communications
infrastructure as portfolios and communications infrastructure in a given
portfolio and its related tenant contracts are not largely independent of the
other communications infrastructure in the portfolio. We re-evaluate the
appropriateness of the pooled groups at least annually. This use of grouping is
based in part on (1) our limitations regarding disposal of communications
infrastructure, (2) the interdependencies of communications infrastructure
portfolios, and (3) the manner in which communications infrastructure is traded
in the marketplace. The vast majority of our site rental contracts and tenant
relationships intangible assets and property and equipment are pooled into the
U.S. owned communications infrastructure group. Secondly, and separately, we
pool site rental contracts and tenant relationships by significant tenant or by
tenant grouping for individually insignificant tenants, as appropriate, for
purposes of determining the unit of account for impairment testing because we
associate the value ascribed to site rental contracts and tenant relationships
intangible assets to the underlying contracts and related tenant relationships
acquired.
Our determination that an adverse event or change in circumstance has occurred
that indicates that the carrying amounts may not be recoverable will generally
involve (1) a deterioration in an asset's financial performance compared to
historical results, (2) a shortfall in an asset's financial performance compared
to forecasted results, or (3) changes affecting the utility and estimated future
demands for the asset. When considering the utility of our assets, we consider
events that would meaningfully impact (1) our communications infrastructure or
(2) our tenant relationships. For example, consideration would be given to
events that impact (1) the structural integrity and longevity of our
communications infrastructure or (2) our ability to derive benefit from our
existing tenant relationships, including events such as tenant's bankruptcy or
insolvency or loss of a significant tenant. During 2019, there were no events or
circumstances that caused us to review the carrying value of our intangible
assets or property and equipment due in part to our assets performing
consistently with or better than our expectations.
If the sum of the estimated future cash flows (undiscounted) from an asset, or
portfolio group, significant tenant or tenant group (for individually
insignificant tenants), as applicable, is less than its carrying amount, an
impairment loss may be recognized. If the carrying value were to exceed the
undiscounted cash flows, measurement of an impairment loss would be based on the
fair value of the asset, which is based on an estimate of discounted future cash
flows. The most important estimates for such calculations of undiscounted cash
flows are (1) the expected additions of new tenants and equipment on our
communications infrastructure and (2) estimates regarding tenant cancellations
and renewals of tenant contracts. We could record impairments in the future if
changes in long-term market conditions, expected future operating results or the
utility of the assets results in changes for our impairment test calculations
which negatively impact the fair value of our property and equipment and
intangible assets, or if we changed our unit of account in the future.
Approximately 2% of our total towers currently have no tenants. We continue to
pay operating expenses on these towers in anticipation of obtaining tenants on
these towers in the future, primarily because of the demographics and continuing
increase in demand for data in the areas around these individual towers. We
estimate, based on current visibility, potential tenants on a majority of these
towers. To the extent we do not believe there are long-term prospects of
obtaining tenants on an individual asset and all other possible avenues for
recovering the carrying value have been exhausted, including sale of the asset,
we appropriately reduce the carrying value of such assets to fair value.
Accounting for Goodwill - Impairment Evaluation. We test goodwill for impairment
on an annual basis, regardless of whether adverse events or changes in
circumstances have occurred. The annual test begins with goodwill and all
intangible assets being allocated to applicable reporting units. We then perform
a qualitative assessment to determine whether it is "more likely than not" that
the fair value of the reporting unit is less than its carrying amount. If we
conclude that it is "more likely than not" that the fair value of a reporting
unit is less than its carrying amount, we would be required to perform the
two-step goodwill impairment test. Otherwise, the two-step goodwill impairment
test is not required. Our reporting units are the same as our operating segments
(Towers and Fiber). See note 16 to our consolidated financial statements. We
performed our most recent annual goodwill impairment test as of October 1, 2019,
which resulted in no impairments.
Deferred Income Taxes. We operate as a REIT for U.S. federal income tax
purposes. Our REIT taxable income is generally not subject to federal and state
income taxes as a result of the deduction for dividends paid and any usage of
our remaining NOLs.  Accordingly, the only provision or benefit for federal
income taxes for the year ended December 31, 2019 relates to TRSs.  Furthermore,
as a result of the deduction for dividends paid, some or all of our NOLs related
to our REIT may expire without utilization.  See "Item 1. Business-Company
Developments, REIT Status and Industry Overview-REIT Status" for a discussion of
the impact of our REIT status.

                                       42
--------------------------------------------------------------------------------

Our TRSs will continue to be subject, as applicable, to federal and state income
taxes and foreign taxes in the jurisdictions in which such assets and operations
are located.  Our ability to utilize our NOLs is dependent, in part, upon us
having sufficient future earnings to utilize our NOLs before they expire. If
market conditions change materially and we determine that we will be unable to
generate sufficient taxable income in the future to utilize our NOLs, we would
be required to record an additional valuation allowance, which would reduce our
earnings. Such adjustments could cause a material effect on our results of
operations for the period of the adjustment. The change in our valuation
allowance has no effect on our cash flows. For a further discussion of our
benefit (provision) for income taxes, see "Item 7. MD&A-Results of Operations"
and note 11 to our consolidated financial statements.

Recent Accounting Pronouncements Not Yet Adopted. See note 3 to our consolidated

Non-GAAP and Segment Financial Measures
In addition to the non-GAAP financial measures used herein and as discussed in
note 16 to our consolidated financial statements, we also provide (1) segment
site rental gross margin, (2) segment 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. 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 services and other gross
margin as segment services and other revenues less segment services and other
cost of operations, which excludes stock-based compensation expense recorded in
consolidated services and other cost of operations. We define segment operating
profit as segment site rental gross margin plus segment 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.
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 communications 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 (loss), net income (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 (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 on retirement of long-term obligations, net (gain) loss on
interest rate swaps, (gains) losses on foreign currency swaps, impairment of
available-for-sale securities, interest income, other (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. Amounts prior to 2019 have been restated to reflect
the impact of the Historical Adjustments as discussed in the "Explanatory Note"
immediately preceding Item 1 of this Annual Report on Form 10-K.

Form 10-K and note 2 to our consolidated financial statements for further

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 communications

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.
