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, 2016 (“Annual Report”), filed with the SEC on February 23, 2017. 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 recorded a $5.3 million liability for unrecognized tax benefits in connection with the acquisition of Network Management Holdings, LTD (“NMS”). See Note 3. We have filed our initial U.S. federal and state income tax returns which are subject to examination. Reclassifications—Certain amounts have been reclassified to conform with current year presentation. Following the acquisition of Network Management Holdings, LTD (“NMS”) in the first quarter of 2017, the Company manages and reports our operations in four reportable business segment: Leasing, Fiber Infrastructure, Towers and Consumer CLEC. Prior year information, including revenues on the Consolidated Statement of Income, has been recast to conform to the current year presentation. See Note 11. We determined that certain immaterial misclassifications existed in the supplemental guarantor information condensed consolidating statements of comprehensive income for the three months ended March 31, 2016. During the first quarter of 2017, certain Non-Guarantor entities became Guarantor entities. Prior year information has been recast to conform to the current year presentation. See Note 14. Recently Issued Accounting Standards In February 2017, the FASB issued Accounting Standards Update (“ASU”) No. 2017-05, Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets (“ASU 2017-05”), which provides guidance for recognizing gains and losses from the transfer of nonfinancial assets and for partial sales of nonfinancial assets, and is effective for financial statements issued for fiscal years and interim periods beginning after December 15, 2017. The Company is currently evaluating the impacts the adoption of this accounting standard will have on our financial statements. In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Accounting for Goodwill Impairment (“ASU 2017-04”), which removes the requirement to perform a hypothetical purchase price allocation to measure goodwill impairment. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. ASU 2017-04 is effective for annual and interim periods beginning January 1, 2020, with early adoption permitted, and applied prospectively. We adopted ASU 2017-04 effective January 1, 2017, and there was no material impact on our financial position, results of operations or cash flows. In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business (“ASU 2017-01”), in an effort to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. ASU 2017-01 is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted. We adopted ASU 2017-01 effective January 1, 2017, with prospective application. As a result of the adoption of ASU 2017-01, the Company’s acquisition of NMS) (see Note 3) was determined to be an asset acquisition. Transaction cost associated with our real property interest investments are now capitalized as opposed to be recorded as an expense as was required prior to adoption of ASU 2017-01. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”). This update 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 intends to adopt the revenue recognition guidance on January 1, 2018. The Company’s implementation efforts include reviewing revenue contracts and the identification of revenue within scope of the guidance. While the Company currently has not identified any material changes in the timing of revenue recognition, the evaluation is ongoing and we are in the process of determining the method of adoption. 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, respectively. 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. The Company is currently evaluating this guidance to determine the impact it will have on our financial statements by reviewing its existing operating lease contracts, where we are the lessee and service contracts that may include embedded leases. The Company expects a gross-up of its Consolidated Balance Sheets as a result of recognizing lease liabilities and right of use assets, the extent of the impact of a gross-up is under evaluation. The Company does not anticipate material changes to the recognition of operating lease expense in its Consolidated Statements of Income. 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.
