Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	Note 2. Basis of Presentation and Summary of Significant Accounting Policies The accompanying Condensed Consolidated Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information set forth in the Accounting Standards Codification (“ASC”), as published by the Financial Accounting Standards Board (“FASB”), and with the applicable rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair statement of results for the interim period have been included. Operating results from any interim period are not necessarily indicative of the results that may be expected for the full fiscal year. The accompanying Condensed Consolidated Financial Statements and related notes should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2015 (“Annual Report”), filed with the SEC on March 7, 2016. Accordingly, significant accounting policies and other disclosures normally provided have been omitted from the accompanying Condensed Consolidated Financial Statements and related notes since such items are disclosed in our Annual Report. All material intercompany balances and transactions have been eliminated. Income Taxes—We currently have no liabilities for uncertain income tax positions. We have filed our initial U.S. federal and state income tax returns which are subject to examination. Business Combinations—In accordance with ASC 805, Business Combinations, we apply the acquisition method of accounting for acquisitions meeting the definition of a business combination, where assets acquired and liabilities assumed are recorded at fair value at the date of each acquisition, and the results of operations are included with those of the Company from the dates of the respective acquisitions. Any excess of the purchase price paid by the Company over the amounts recognized for assets acquired and liabilities assumed is recorded as goodwill. ASC 805 also requires acquirers, among other things, to estimate the acquisition date fair value of any contingent consideration and to recognize any subsequent changes in the fair value of contingent consideration in earnings. The Company continues to evaluate acquisitions for a period not to exceed one year after the applicable acquisition date of each transaction to determine whether any additional adjustments are needed to the allocation of the purchase price paid for the assets acquired and liabilities assumed. Goodwill—Goodwill is recognized for the excess of purchase price over the fair value of net assets of businesses acquired. Goodwill is reviewed for impairment at least annually. In accordance with ASC 350-20, Intangibles-Goodwill and Other, we evaluate goodwill for impairment between annual impairment tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. Unless circumstances otherwise dictate, the annual impairment test is performed in the fourth quarter. Property, Plant and Equipment—Property, plant and equipment is stated at original cost, net of accumulated depreciation. The Company capitalizes costs incurred in bringing property, plant and equipment to an operational state, including all activities directly associated with the acquisition, construction, and installation of the related assets it owns. The Company also enters into leasing arrangements providing for the long‑term use of constructed fiber that is then integrated into the Company’s network infrastructure. For each lease that qualifies as a capital lease, the present value of the lease payments, which may include both periodic lease payments over the term of the lease as well as upfront payments to the lessor, is capitalized at the inception of the lease and included in property and equipment. Certain property, plant and equipment are depreciated using a group composite depreciation method. Under this method, when property is retired, the original cost, net of salvage value, is charged against accumulated depreciation and no immediate gain or loss is recognized on the disposition of the property. For all other property, which includes amortization of capital lease assets, depreciation is computed using the straight-line method over the estimated useful life of the respective property. When the property is retired or otherwise disposed of, the related cost and accumulated depreciation are written-off, with the corresponding gain or loss reflected in operating results. Costs of maintenance and repairs to property, plant and equipment subject to the Master Lease are the responsibility of our tenant. Costs of maintenance and repairs to property, plant and equipment not subject to triple-net leasing arrangements are expensed as incurred. We acquire real property interests from third parties who own land where communications infrastructure assets are located and desire to monetize the underlying real property. These real property interests entitle us to receive rental payments from leases on our sites. The financial results of the acquired real property interests are included in the Leasing segment from the date of acquisition and were not material, individually or in the aggregate, to our results of operations. Real property interests are recorded in real estate investments on our Condensed Consolidated Balance Sheet. Foreign Currency Translation—The financial statements of our international subsidiaries whose functional currency is the local currency are translated into U.S. dollars using the exchange rate at the balance sheet date for assets and liabilities and the weighted average exchange rate for the applicable period for revenues, expenses, gains and losses. Translation adjustments are recorded as a separate component of comprehensive income in stockholders’ equity. Reclassifications—Certain amounts have been reclassified to conform with current year presentation. We determined that certain immaterial misclassifications existed in the supplemental guarantor information condensed consolidating statements of comprehensive income and statement of cash flows for the period April 24, 2015 to September 30, 2015. See Note 15. Transaction Related Costs—The Company expenses transaction related costs in the period in which they are incurred and services are received. Transaction related costs include incremental acquisition pursuit, transaction and integration costs, including unsuccessful acquisition pursuit costs. Pursuit and transaction costs include professional services (legal, accounting, advisory, regulatory, etc.), finder’s fees, travel expenses, and other direct expenses associated with an acquisition. Integration costs include direct costs necessary to integrate an acquired business, including professional services, systems and data conversion, severance and retention bonuses payable to employees of an acquired business. Recently Issued Accounting Standards In May 2014, the FASB issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”). The standard outlines a single comprehensive revenue recognition model for entities to follow in accounting for revenue from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model is that an entity should recognize revenue for the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to receive for those goods or services. ASU 2014-09 is effective for annual periods beginning after December 15, 2017 and interim periods within those annual periods. Early adoption is permitted for public companies for annual periods beginning after December 15, 2016. The Company is in the process of evaluating this guidance to determine the impact it will have on our financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (“ASC 842”), which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e. lessees and lessors). The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight line basis over the term of the lease. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases today. ASC 842 is effective for fiscal years and interim periods beginning after December 15, 2018, and early adoption is permitted. The Company is in the process of evaluating this guidance to determine the impact it will have on our financial statements. In March 2016, the FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”). ASU 2016-09 simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years and early adoption is permitted. We adopted ASU 2016-09 effective April 1, 2016, and will reverse compensation cost of forfeited awards as they occur. At the time of adoption, we had not experienced any forfeited awards and therefore no cumulative-effect adjustment was necessary. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”). ASU 2016-15 provides guidance on reducing the diversity in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. In addition to other specific cash flow issues, ASU 2016-15 provides clarification on when an entity should separate cash receipts and cash payments into more than one class of cash flows and when an entity should classify those cash receipts and payments into one class of cash flows on the basis of predominance. The new guidance is effective for the fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, and early adoption is permitted. The Company is currently evaluating the impacts the adoption of this accounting standard will have on our financial statements.
