Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Note 1 – Basis of Presentation

The unaudited condensed consolidated financial statements of T-Mobile US, Inc. (“T-Mobile” or the “Company”) include all adjustments of a normal recurring nature necessary for the fair presentation of the results for the interim periods presented. The results for the interim periods are not necessarily indicative of those for the full year. The condensed consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2014. Certain prior period amounts have been reclassified to conform to the current presentation.

The condensed consolidated financial statements include the balances and results of operations of T-Mobile and its consolidated subsidiaries. T-Mobile consolidates all majority-owned subsidiaries over which it exercises control, as well as variable interest entities (“VIE”) where it is deemed to be the primary beneficiary and VIEs which cannot be deconsolidated. Intercompany transactions and balances have been eliminated in consolidation.

The preparation of financial statements in conformity with United States (“U.S.”) generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions which affect the financial statements and accompanying notes. Estimates are based on historical experience, where applicable, and other assumptions which management believes are reasonable under the circumstances. These estimates are inherently subject to judgment and actual results could differ from those estimates.

Recently-Issued Accounting Standards

In April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-03, “Simplifying the Presentation of Debt Issuance Costs.” The standard requires debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected. The standard will become effective for T-Mobile beginning January 1, 2016. The implementation of this standard is not expected to have a significant impact on T-Mobile’s consolidated financial statements.

In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers.” The standard requires entities to recognize revenue through the application of a five-step model, which includes identification of the contract, identification of the performance obligations, determination of the transaction price, allocation of the transaction price to the performance obligations, and recognition of revenue as the entity satisfies the performance obligations. In August 2015, the FASB issued ASU 2015-14, “Revenue From Contracts With Customers (Topic 606): Deferral of the Effective Date.” The amendments in the ASU 2015-14 defer the effective date of ASU 2014-09 by one year. The standard will become effective for T-Mobile beginning January 1, 2018; however, early adoption with the original effective date for periods beginning January 1, 2017 will be permitted.  The Company is currently evaluating the guidance to determine the potential impact on T-Mobile’s consolidated financial statements.
