Segment Reporting [Abstract] |
Business Segment Information | Business Segment Information In the first quarter of 2025, we reorganized our operating segments as a result of the way our CODM evaluates the performance of operations, develops strategy and allocates resources, including capital. Our sulfur services business, formerly reported under our soda and sulfur services reporting segment with our previously owned Alkali Business (see Note 4), is now reported under our onshore transportation and services reporting segment. As a result of this change, we now manage our businesses through three divisions that constitute our reportable segments. Our reportable segments are primarily organized around the different products and services we provide to our customers and include the following: (i) offshore pipeline transportation; (ii) marine transportation; and (iii) onshore transportation and services. Our offshore pipeline transportation segment consists of our offshore transportation of crude oil and natural gas in the Gulf of America, which focuses on providing a suite of services to integrated and large independent energy companies. Our marine transportation segment provides waterborne transportation of petroleum products (primarily fuel oil, asphalt and other heavy refined products) and crude oil throughout North America primarily to customers such as refiners and large energy companies. Our onshore transportation and services segment provides services through a combination of purchasing, transporting, storing, blending and marketing crude oil and petroleum products primarily to crude oil refiners and producers and performs the processing of high sulfur (or “sour”) gas streams for refineries to remove the sulfur and selling the related by-product, NaHS (our sulfur services business). Substantially all of our revenues are derived from, and substantially all of our assets are located in, the United States. Our CODM evaluates segment performance based on a variety of measures including Segment Margin, segment volumes, and, where relevant, capital investment. Segment Margin is viewed by our CODM as the primary measure that is most aligned with the measurement principles most consistent with those used in calculating the corresponding amounts in our Unaudited Condensed Consolidated Financial Statements. We define Segment Margin as revenues less product costs, operating expenses (excluding non-cash gains and charges, such as depreciation, amortization and accretion), segment general and administrative expenses, all of which are net of the effects of our noncontrolling interests, plus our equity in distributable cash generated by our equity investees and unrestricted subsidiaries. In addition, our Segment Margin definition excludes the non-cash effects of our long-term incentive compensation plan.
