Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation and Consolidation	Note 2. Basis of Presentation and Consolidation The accompanying Consolidated Financial Statements include all accounts of the Company and, its wholly-owned and/or controlled subsidiaries, which includes the Operating Partnership. Under the Accounting Standards Codification 810, Consolidation (“ASC 810”), the Operating Partnership is considered a variable interest entity and is consolidated in the Consolidated Financial Statements of Uniti Group Inc. as the Company has determined to be the primary beneficiary. All material intercompany balances and transactions have been eliminated. ASC 810 provides guidance on the identification of entities for which control is achieved through means other than voting rights (“variable interest entities” or “VIEs”) and the determination of which business enterprise, if any, should consolidate the VIEs. Generally, the consideration of whether an entity is a VIE applies when either: (1) the equity investors (if any) lack (i) the ability to make decisions about the entity’s activities through voting or similar rights, (ii) the obligation to absorb the expected losses of the entity, or (iii) the right to receive the expected residual returns of the entity; (2) the equity investment at risk is insufficient to finance that entity’s activities without additional subordinated financial support; or (3) the equity investors have voting rights that are not proportionate to their economic interests and substantially all of the activities of the entity involve or are conducted on behalf of an investor with a disproportionately small voting interest. The Company consolidates VIEs in which it is considered to be the primary beneficiary. The primary beneficiary is defined as the entity having both of the following characteristics: (1) the power to direct the activities that, when taken together, most significantly impact the VIE’s performance; and (2) the obligation to absorb losses and right to receive the returns from the VIE that would be significant to the VIE. The accompanying Consolidated Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for 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”).
