	Summary of Significant Accounting Policies

Restricted Cash

Restricted cash represents (1) the cash held in reserve by the indenture trustees pursuant to the indenture governing certain of the Company's debt instruments, (2) cash securing performance obligations such as letters of credit, as well as (3) any other cash whose use is limited by contractual provisions. The restriction of rental cash receipts is a critical feature of certain of the Company's debt instruments, due to the applicable indenture trustee's ability to utilize the restricted cash for the payment of (1) debt service costs, (2) ground rents, (3) real estate or personal property taxes, (4) insurance premiums related to towers, (5) other assessments by governmental authorities and potential environmental remediation costs, or (6) a portion of advance rents from tenants. The restricted cash in excess of required reserve balances is subsequently released to the Company in accordance with the terms of the indentures. The Company has classified the increases and decreases in restricted cash as (1) cash provided by financing activities for cash held by indenture trustees based on consideration of the terms of the related indebtedness, although the cash flows have aspects of both financing activities and operating activities, (2) cash provided by investing activities for cash securing performance obligations and restricted cash that is acquired in acquisitions, or (3) cash provided by operating activities for the other remaining restricted cash.

The following table is a summary of the impact of restricted cash on the statement of cash flows.



	For the years ended December 31,
	2014			2013				2012
Net cash provided by (used from) operating activities	$	6,148		$	(1,637	)		$	11,475

(a)	Inclusive of $46.3 million of acquired restricted cash.


(b)	Inclusive of $316.6 million of cash held by the trustee as of December 31, 2012 and subsequently released to retire the 7.75% Secured Notes in January 2013.

Receivables Allowance

An allowance for doubtful accounts is recorded as an offset to accounts receivable. The Company uses judgment in estimating this allowance and considers historical collections, current credit status, or contractual provisions. Additions to the allowance for doubtful accounts are charged either to "site rental costs of operations" or to "network services and other costs of operations," as appropriate; and deductions from the allowance are recorded when specific accounts receivable are written off as uncollectible.

Lease Accounting

General. The Company classifies its leases at inception as either operating leases or capital leases. A lease is classified as a capital lease if at least one of the following criteria are met, subject to certain exceptions noted below: (1) the lease transfers ownership of the leased assets to the lessee, (2) there is a bargain purchase option, (3) the lease term is equal to 75% or more of the economic life of the leased assets, or (4) the present value of the minimum lease payments equals or exceeds 90% of the fair value of the leased assets.

Lessee. Leases for land are evaluated for capital lease treatment if at least one of the first two criteria mentioned in the immediately preceding paragraph is present relating to the leased assets. When the Company, as lessee, classifies a lease as a capital lease, it records an asset in an amount equal to the present value of the minimum lease payments under the lease at the beginning of the lease term. Applicable operating leases are recognized on a straight-line basis as discussed under "costs of operations" below.

Lessor. If the Company is the lessor of leased property that is part of a larger whole (including with respect to a portion of space on a tower) and for which fair value is not objectively determinable, then such a lease is accounted for as an operating lease. As applicable, operating leases are recognized on a straight-line basis as discussed under "Revenue Recognition."

Property and Equipment

Property and equipment is stated at cost, net of accumulated depreciation. Property and equipment includes land owned in fee and perpetual easements for land which have no definite life. When the Company purchases fee ownership or perpetual easements for the land previously subject to ground lease, the Company reduces the value recorded as land by the amount of any associated deferred ground lease payable or unamortized above-market leases. Depreciation is computed utilizing the straight-line method at rates based upon the estimated useful lives of the various classes of assets. Depreciation of wireless infrastructure is computed with a useful life equal to the shorter of 20 years or the term of the underlying ground lease (including optional renewal periods). Additions, renewals, and improvements are capitalized, while maintenance and repairs are expensed. Interest costs incurred related to the construction of certain property and equipment are capitalized. The carrying value of property and equipment will be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable.

Abandonments and write-offs of property and equipment are recorded to "asset write-downs charges" on the Company's consolidated statement of operations and comprehensive income (loss) and were $10.1 million, $10.2 million, and $12.0 million for the years ended December 31, 2014, 2013, and 2012, respectively.

Asset Retirement Obligations

Pursuant to its ground lease and easement agreements, the Company records obligations to perform asset retirement activities, including requirements to remove wireless infrastructure or remediate the land upon which the Company's wireless infrastructure resides. Asset retirement obligations are included in "other long-term liabilities" on the Company's consolidated balance sheet. The liability accretes as a result of the passage of time and the related accretion expense is included in "depreciation, amortization, and accretion" on the Company's consolidated statement of operations and comprehensive income (loss). The associated asset retirement costs are capitalized as an additional carrying amount of the related long-lived asset and depreciated over the useful life of such asset.

Goodwill

Goodwill represents the excess of the purchase price for an acquired business over the allocated value of the related net assets. The Company tests 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. The Company then performs a qualitative assessment to determine whether it is "more likely than not" that the fair value of the reporting units is less than its carrying amount. If it is concluded that it is "more likely than not" that the fair value of a reporting unit is less than its carrying amount, it is necessary to perform the two-step goodwill impairment test. The two-step goodwill impairment test begins with an estimation of fair value of the reporting unit using an income approach, which looks to the present value of expected future cash flows. The first step, commonly referred to as a "step-one impairment test," is a screen for potential impairment while the second step measures the amount of impairment if there is an indication from the first step that one exists. The Company's measurement of the fair value for goodwill is based on an estimate of discounted future cash flows of the reporting unit. The Company performed its most recent annual goodwill impairment test as of October 1, 2014, which resulted in no impairments.

Intangible Assets

Intangible assets are included in "site rental contracts and customer relationships, net" and "other intangible assets, net" on the Company's consolidated balance sheet and predominately consist of the estimated fair value of the following items recorded in conjunction with acquisitions: (1) site rental contracts and customer relationships, (2) below-market leases for land interest under the acquired wireless infrastructure, (3) term easement rights for land interest under the acquired wireless infrastructure, or (4) other contractual rights such as trademarks. The site rental contracts and customer relationships intangible assets are comprised of (1) the current term of the existing leases, (2) the expected exercise of the renewal provisions contained within the existing leases, which automatically occur under contractual provisions, or (3) any associated relationships that are expected to generate value following the expiration of all renewal periods under existing leases.

The useful lives of intangible assets are estimated based on the period over which the intangible asset is expected to benefit the Company and gives consideration to the expected useful life of other assets to which the useful life may relate. 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 customer relationships intangible asset is limited by the maximum depreciable life of the wireless infrastructure (20 years), as a result of the interdependency of the wireless infrastructure and site rental leases. In contrast, the site rental contracts and customer 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 customer relationships are valued based upon the fair value, 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 and customer relationships 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 wireless infrastructure.

The carrying value of other intangible assets with finite useful lives will be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. The Company has a dual grouping policy for purposes of determining the unit of account for testing impairment of the site rental contracts and customer relationships intangible assets. First, the Company pools the site rental contracts and customer relationships with the related wireless infrastructure assets into portfolio groups for purposes of determining the unit of account for impairment testing. Second and separately, the Company evaluates the site rental contracts and customer relationships by significant tenant or by tenant grouping for individually insignificant tenants, as appropriate. If the sum of the estimated future cash flows (undiscounted) expected to result from the use or eventual disposition of an asset is less than the carrying amount of the asset, an impairment loss is recognized. Measurement of an impairment loss is based on the fair value of the asset.

Deferred Credits

Deferred credits are included in “deferred revenues” and “other long-term liabilities” on the Company's consolidated balance sheet and consist of the estimated fair value of the following items recorded in conjunction with acquisitions: (1) below-market tenant leases for contractual interests with tenants on acquired wireless infrastructure, which are amortized to site rental revenues and (2) above-market leases for land interests under the Company's wireless infrastructure, which are amortized to site rental cost of operations.

Fair value for these deferred credits represents the difference between (1) the stated contractual payments to be made pursuant to the in-place lease and (2) management's estimate of fair market lease rates for each corresponding lease. Deferred credits are measured over a period equal to the estimated remaining economic lease term considering renewal provisions or economics associated with those renewal provisions, to the extent applicable. Deferred credits are amortized over their respected estimated lease terms at the time of acquisition.

Deferred Financing Costs

Third-party costs incurred to obtain financing are deferred and are included in "long-term prepaid rent, deferred financing costs, and other assets" on the Company's consolidated balance sheet.

Revenue Recognition

Site rental revenues are recognized on a monthly basis over the fixed, non-cancelable term of the relevant lease (generally ranging from five to 15 years), regardless of whether the payments from the tenant are received in equal monthly amounts. The Company's leases contain fixed escalation clauses (such as fixed dollar or fixed percentage increases) or inflation-based escalation clauses (such as those tied to the consumer price index ("CPI")). 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 are included in "other current assets" and "deferred site rental receivables." Amounts billed or received prior to being earned are deferred and reflected in "deferred revenues" and "other long-term liabilities."

Network services revenues are recognized after completion of the applicable service. Nearly all of the antenna installation services are billed on a cost-plus profit basis and site development services are billed on a fixed fee basis.

Sales taxes or value-added taxes collected from customers and remitted to governmental authorities are presented on a net basis.

Costs of Operations

In excess of two-thirds of the Company's site rental costs of operations expenses consist of ground lease expenses, and the remainder includes property taxes, repairs and maintenance expenses, employee compensation or related benefit costs, or utilities. Generally, the ground leases for land are specific to each site and are for an initial term of five years and are renewable for pre-determined periods. The Company also enters into term easements and ground leases in which it prepays the entire term in advance. Ground lease expense is recognized on a monthly basis, regardless of whether the lease agreement payment terms require the Company to make payments annually, quarterly, monthly, or for the entire term in advance. The Company's ground leases contain fixed escalation clauses (such as fixed dollar or fixed percentage increases) or inflation-based escalation clauses (such as those tied to the CPI). If the payment terms include fixed escalation provisions, the effect of such increases is recognized on a straight-line basis. The Company calculates the straight-line ground lease expense using a time period that equals or exceeds the remaining depreciable life of the wireless infrastructure asset. Further, when a tenant has exercisable renewal options that would compel the Company to exercise existing ground lease renewal options, the Company has straight-lined the ground lease expense over a sufficient portion of such ground lease renewals to coincide with the final termination of the tenant's renewal options. The Company's non-current liability related to straight-line ground lease expense is included in "other long-term liabilities" on the Company's consolidated balance sheet. The Company's asset related to prepaid ground leases is included in "prepaid expenses" and "long-term prepaid rent, deferred financing costs and other assets, net" on the Company's consolidated balance sheet.

Network services and other costs of operations predominately consist of third party service providers such as contractors and professional service firms and, to a lesser extent, internal labor costs. As of December 31, 2014 and 2013, the Company had $60.4 million and $52.2 million, respectively, of work in process.

Acquisition and Integration Costs

All direct or incremental costs related to a business combination are expensed as incurred. Costs include severance, retention bonuses payable to employees of an acquired enterprise, temporary employees to assist with the integration of the acquired operations, or fees paid for services such as consulting, accounting, legal, or engineering reviews. These business combination costs are included in "acquisition and integration costs" on the Company's consolidated statement of operations and comprehensive income (loss). The vast majority of the Company's acquisition and integration costs during the years ended December 31, 2014, 2013, and 2012 relate to the AT&T Acquisition (as defined in note 3) and the 2012 Acquisitions (as defined in note 3).

Stock-Based Compensation

Restricted Stock Awards and Restricted Stock Units. The Company records stock-based compensation expense only for those unvested restricted stock awards ("RSAs") and unvested restricted stock units ("RSUs") for which the requisite service is expected to be rendered. The cumulative effect of a change in the estimated number of RSAs and RSUs for which the requisite service is expected to be or has been rendered is recognized in the period of the change in the estimate. To the extent that the requisite service is rendered, compensation cost for accounting purposes is not reversed; rather, it is recognized regardless of whether or not the awards vest. A discussion of the Company's valuation techniques and related assumptions and estimates used to measure the Company's stock-based compensation is as follows:

Valuation. The fair value of RSAs and RSUs without market conditions is determined based on the number of shares relating to such RSAs and RSUs and the quoted price of the Company's common stock at the date of grant. The Company estimates the fair value of RSAs and RSUs with market conditions granted using a Monte Carlo simulation. The Company's determination of the fair value of RSAs and RSUs with market conditions on the date of grant is affected by its common stock price as well as assumptions regarding a number of highly complex or subjective variables. The determination of fair value using a Monte Carlo simulation requires the input of subjective assumptions, and other reasonable assumptions could provide differing results.

Amortization Method. The Company amortizes the fair value of all RSAs and RSUs on a straight-line basis for each separately vesting tranche of the award (graded vesting schedule) over the requisite service periods.

Expected Volatility. The Company estimates the volatility of its common stock at the date of grant based on the historical volatility of its common stock.

Expected Dividend Rate. The expected dividend rate at the date of grant is based on the then-current dividend yield.

Risk-Free Rate. The Company bases the risk-free rate on the implied yield currently available on U.S. Treasury issues with an equivalent remaining term equal to the expected life of the award.

Forfeitures. The Company uses historical data and management's judgment about the future employee turnover rates to estimate the number of shares for which the requisite service period will not be rendered.

Interest Expense and Amortization of Deferred Financing Costs

The components of interest expense and amortization of deferred financing costs are as follows:



	Years Ended December 31,
	2014			2013		2012
Interest expense on debt obligations	$	492,437		$	490,385	$	491,694
Amortization of deferred financing costs	22,190			25,120		23,324
Amortization of adjustments on long-term debt	(3,628		)	8,541		21,297
Amortization of interest rate swaps	63,148			64,928		65,239
Other, net of capitalized interest	(856		)	656		(510		)
Total	$	573,291		$	589,630	$	601,044

The Company amortizes deferred financing costs, discounts, premiums, and purchase price adjustments on long-term debt over the estimated term of the related borrowing using the effective interest yield method. Discounts or purchase price adjustments are presented as a reduction to the related debt obligation on the Company's consolidated balance sheet.

Income Taxes

Effective January 1, 2014, the Company commenced operating 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 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) taxes related to the TRSs, (4) certain state, local, or foreign income taxes, (5) franchise taxes, (6) property taxes, and (7) 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 1986, as amended ("Code") to maintain qualification for taxation as a REIT.

The Company's small cells are currently included in one or more wholly owned TRSs. In August 2014, the Company received a favorable private letter ruling from the Internal Revenue Service ("IRS"), which provides that the real property portion of the Company's small cells and the related rents qualify as real property and rents from real property, respectively, under the rules governing REITs. The Company is evaluating the impact of this private letter ruling and, subject to board approval, expects to take appropriate action to include at least some part of the Company's small cells as part of the REIT during 2015. Once the Company has completed its evaluation and necessary actions to include small cells in the REIT, the Company expects to de-recognize its net deferred tax liabilities related to such part of the Company's small cells.

Additionally, the Company has included in TRSs its tower operations in Australia and certain other assets and operations. Those TRS assets and operations (along with any part of the Company's small cells that remain in a TRS) will continue to be subject, as applicable, to federal and state corporate income taxes or to foreign taxes in the jurisdictions in which such assets and operations are located. The Company's foreign assets and operations (including its tower operations in Puerto Rico and Australia) most likely will be subject to foreign income taxes in the jurisdictions in which such assets and operations are located, regardless of whether they are included in a TRS or not. The Company will be subject to a federal corporate level tax rate (currently 35%) on the gain recognized from the sale of assets occurring within a specified period (generally 10 years) after the REIT conversion up to the amount of the built in gain that existed on January 1, 2014, which is based upon the fair market value of those assets in excess of the Company's tax basis on January 1, 2014. This gain can be offset by any remaining federal net operating loss carryforwards ("NOLs").

During 2013, the Company de-recognized substantially all of its previously recorded U.S. federal and state deferred tax assets and liabilities in connection with completing the steps necessary to qualify to operate as a REIT and receiving final approval from the Company's board of directors. The de-recognized U.S. federal and state deferred tax assets related to the entities included in the REIT, because the expected recovery or settlement of the related assets and liabilities would not result in a taxable or deductible amount in the future.

For the Company's TRSs, the Company accounts for income taxes using an asset and liability approach, which requires the recognition of deferred income tax assets and liabilities for the expected future tax consequences of events that have been recognized in the Company's financial statements or tax returns. Deferred income tax assets and liabilities are determined based on the temporary differences between the financial statement and tax bases of assets and liabilities using enacted tax rates. A valuation allowance is provided on deferred tax assets if it is determined that it is "more likely than not" that the asset will not be realized. The Company records a valuation allowance against deferred tax assets when it is "more likely than not" that some portion or all of the deferred tax asset will not be realized. The Company reviews the recoverability of deferred tax assets each quarter and based upon projections of future taxable income, reversing deferred tax liabilities or other known events that are expected to affect future taxable income, records a valuation allowance for assets that do not meet the "more likely than not" realization threshold. Valuation allowances may be reversed if related deferred tax assets are deemed realizable based upon changes in facts and circumstances that impact the recoverability of the asset.

The Company recognizes a tax position if it is "more likely than not" that it will be sustained upon examination. The tax position is measured at the largest amount that is greater than 50 percent likely of being realized upon ultimate settlement. The Company reports penalties and tax-related interest expense as a component of the benefit (provision) for income taxes. As of December 31, 2014 and 2013, the Company has not recorded any penalties related to its income tax positions.

Per Share Information

Basic net income (loss) attributable to CCIC common stockholders, per common share excludes dilution and is computed by dividing net income (loss) attributable to CCIC common stockholders by the weighted-average number of common shares outstanding during the period. Diluted income (loss) attributable to CCIC common stockholders, per common share is computed by dividing net income (loss) attributable to CCIC common stockholders by the weighted-average number of common shares outstanding during the period plus any potential dilutive common share equivalents, including shares issuable (1) upon the vesting of RSAs and RSUs as determined under the treasury stock method and (2) upon conversion of the Company's Convertible Preferred Stock (as defined in note 11), as determined under the if-converted method.

A reconciliation of the numerators and denominators of the basic and diluted per share computations is as follows:



	Years Ended December 31,
	2014			2013			2012
Net income (loss) attributable to CCIC stockholders	$	390,513		$	90,111		$	188,584
Dividends on preferred stock	(43,988		)	(11,363		)	(2,629		)
Net income (loss) attributable to CCIC common stockholders	$	346,525		$	78,748		$	185,955
Weighted-average number of common shares outstanding (in thousands):
Basic weighted-average number of common stock outstanding	332,302			298,083			289,285
Effect of assumed dilution from potential common shares relating to RSAs and RSUs	963			1,210			1,985
Diluted weighted-average number of common shares outstanding	333,265			299,293			291,270
Net income (loss) attributable to CCIC common stockholders, per common share:
Basic	$	1.04		$	0.26		$	0.64
Diluted	$	1.04		$	0.26		$	0.64

For the years ended December 31, 2014 and 2013, 12.5 million and 13.2 million common share equivalents related to the Convertible Preferred Stock, respectively, were excluded from the dilutive common shares because the impact of such conversion would be anti-dilutive, based on the Company's common stock price as of the end of each such year. See notes 11 and 12.

Foreign Currency Translation

The Company's international operations use the local currency as their functional currency. The Company translates the results of these international operations using the applicable average exchange rate for the period, and translates the assets and liabilities using the applicable exchange rate at the end of the period. The cumulative effect of changes in the exchange rate is recorded as "foreign currency translation adjustments" in other comprehensive income (loss). See note 15.

Fair Values

The Company's assets and liabilities recorded at fair value are categorized based upon a fair value hierarchy that ranks the quality and reliability of the information used to determine fair value. The three levels of the fair value hierarchy are (1) Level 1 — quoted prices (unadjusted) in active and accessible markets, (2) Level 2 — observable prices that are based on inputs not quoted in active markets but corroborated by market data, and (3) Level 3 — unobservable inputs and are not corroborated by market data. The Company evaluates fair value hierarchy level classifications quarterly, and transfers between levels are effective at the end of the quarterly period.

The fair value of cash and cash equivalents and restricted cash approximate the carrying value. The Company determines fair value of its debt securities based on indicative quotes (that is non-binding quotes) from brokers that require judgment to interpret market information including implied credit spreads for similar borrowings on recent trades or bid/ask prices or quotes from active markets if applicable. There were no changes since December 31, 2013 in the Company's valuation techniques used to measure fair values. See note 9 for a further discussion of fair values.

Derivative Instruments

The Company had previously entered into interest rate swaps to manage or reduce its interest rate risk. Derivative financial instruments were entered into for periods that matched the related underlying exposures. The Company can designate derivative financial instruments as hedges. The Company can also enter into derivative financial instruments that are not designated as accounting hedges.

Derivatives were recognized on the consolidated balance sheet at fair value. If the derivative was designated as a cash flow hedge, the effective portion of the change in the fair value of the derivative was recorded as a separate component of stockholders' equity, captioned "accumulated other comprehensive income (loss)," and recognized as increases or decreases to "interest expense and amortization of deferred financing costs" when the hedged item affects earnings. If a hedge ceased to qualify for hedge accounting, any change in the fair value of the derivative since the date it ceased to qualify was recorded to "net gain (loss) on interest rate swaps." However, any amounts previously recorded to "accumulated other comprehensive income (loss)" would remain there until the original forecasted transaction affected earnings. In situations where it becomes probable that the hedged forecasted transaction will not occur, any gains or losses that have been recorded to "accumulated other comprehensive income (loss)" are immediately reclassified to earnings.

Recently Adopted Accounting Pronouncements

No accounting pronouncements adopted during the year ended December 31, 2014 had a material impact on the Company's consolidated financial statements.

Recent Accounting Pronouncements Not Yet Adopted

In May 2014, the Financial Accounting Standards Board ("FASB") released updated guidance regarding the recognition of revenue from contracts with customers, exclusive of those contracts within lease accounting. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should apply the following steps: (1) identify the contracts with the customer; (2) identify the performance obligations in the contract; (3) determine the contract price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when (or as) the entity satisfies a performance obligation. This guidance is effective for the Company as of January 1, 2017. This guidance is required to be applied (1) retrospectively to each prior reporting period presented, or (2) with the cumulative effect being recognized at the date of initial application. The Company is evaluating the guidance including the impact on its consolidated financial statements.
