| Segment Reporting Disclosure [Text Block] |
Segment Reporting Description of Segments Our consolidated financial statements reflect three reportable segments: Fuel Distribution, Pipeline Systems and Terminals. Fuel Distribution. Our Fuel Distribution segment supplies motor fuel to independently-operated dealer stations, distributors, commission agents and other consumers. Also included in our Fuel Distribution segment is lease income from properties that we lease or sublease, as well as the Partnership’s credit card services, franchise royalties and retail operations in Hawaii and New Jersey. Pipeline Systems. As of September 30, 2025, our Pipeline Systems segment included an integrated pipeline and terminal network comprised of approximately 6,000 miles of refined product pipeline (including the pipeline of J.C. Nolan), approximately 6,000 miles of crude oil pipeline (including the pipeline of ET-S Permian), approximately 2,000 miles of ammonia pipeline and 67 terminals. Terminals. As of September 30, 2025, our Terminals segment was composed of four transmix processing facilities and 56 refined product terminals (two in Europe, six in Hawaii and 48 in the continental United States). Segment Operating Results We report Adjusted EBITDA by segment as a measure of segment performance. We define Adjusted EBITDA as earnings before net interest expense, income taxes, depreciation, amortization and accretion expense, non-cash unit-based compensation expense, gains and losses on disposal of assets, non-cash impairment charges, losses on extinguishment of debt, unrealized gains and losses on commodity derivatives, inventory valuation adjustments, and certain other operating expenses reflected in net income that we do not believe are indicative of ongoing core operations. Inventory valuation adjustments that are excluded from the calculation of Adjusted EBITDA represent changes in lower of cost or market reserves on the Partnership's inventory. These amounts are unrealized valuation adjustments applied to fuel volumes remaining in inventory at the end of the period.
