Segment Reporting [Abstract] |
Reportable Segment | 11. REPORTABLE SEGMENT Segment overview. The Partnership’s chief operating decision maker (“CODM”) is the Partnership’s President and Chief Executive Officer who assesses performance and allocates resources on a consolidated basis due to the similar nature of services provided to customers across the Partnership’s domestic asset portfolio. The CODM does not assess performance and allocate resources separately for Western Midstream Operating, LP. Accordingly, the Partnership has a single operating and reportable segment, all the assets of which are in the United States and gather, compress, treat, process, and transport natural gas; gather, stabilize, and transport condensate, NGLs, and crude oil; and gather and dispose of produced water. See Revenue and cost of product in Note 1. Performance measures. Adjusted EBITDA attributable to Western Midstream Partners, LP (“Adjusted EBITDA”) is used as the performance measure by the Partnership’s CODM in assessing performance and allocating resources to the Partnership’s single operating and reportable segment. Net income (loss) is the most comparable GAAP metric to the performance metric of non-GAAP Adjusted EBITDA. The Partnership defines Adjusted EBITDA as net income (loss), plus (i) distributions from equity investments, (ii) non-cash equity-based compensation expense, (iii) interest expense, (iv) income tax expense, (v) depreciation and amortization, (vi) impairments, and (vii) other expense (including lower of cost or market inventory adjustments recorded in cost of product), less (i) gain (loss) on divestiture and other, net, (ii) gain (loss) on early extinguishment of debt, (iii) income from equity investments, (iv) income tax benefit, (v) other income, and (vi) the noncontrolling interest owners’ proportionate share of revenues and expenses. Adjusted EBITDA is a non-GAAP financial measure that the CODM utilizes to assess (i) the Partnership’s operating performance as compared to other publicly traded partnerships in the midstream industry, without regard to financing methods, capital structure, or historical cost basis, (ii) the ability of the Partnership’s assets to generate cash flow to make distributions, and (iii) the viability of acquisitions and capital expenditures and the returns on investment of various investment opportunities. The Partnership’s calculation of Adjusted EBITDA may or may not be comparable to similarly titled measures used by others. 11. REPORTABLE SEGMENT Summarized financial information. The following table presents information about the Partnership’s single operating and reportable segment including (i) total revenues and other, (ii) significant expenses, and (iii) other segment items:
