Segment Information | Segment Information Reporting Segments Operating segments are defined as components of an enterprise for which separate financial information is available that is regularly evaluated by the chief operating decision maker (“CODM”) in deciding how to allocate resources and assess performance. We are comprised of three reportable segments: International Services, U.S. Services and Tubular Sales. The International Services segment provides tubular services in international offshore markets and in several onshore international regions. Our customers in these international markets are primarily large exploration and production companies, including integrated oil and gas companies and national oil and gas companies. The U.S. Services segment provides tubular services in almost all of the active onshore oil and gas drilling regions in the U.S., including the Permian Basin, Bakken Shale, Barnett Shale, Eagle Ford Shale, Haynesville Shale, Marcellus Shale and Utica Shale, as well as in the U.S. Gulf of Mexico. The Tubular Sales segment designs and distributes large outside diameter ("OD") pipe, connectors and casing attachments and sells large OD pipe originally manufactured by various pipe mills. We also provide specialized fabrication and welding services in support of offshore projects, including drilling and production risers, flowlines and pipeline end terminations, as well as long length tubulars (up to 300 feet in length) for use as caissons or pilings. This segment also designs and manufactures proprietary equipment for use in our International and U.S. Services segments. Adjusted EBITDA We define Adjusted EBITDA as income (loss) from continuing operations before net interest income or expense, depreciation and amortization, income tax benefit or expense, asset impairments, gain or loss on sale of assets, foreign currency gain or loss, equity-based compensation, unrealized and realized gain or loss, other non-cash adjustments and unusual charges. We review Adjusted EBITDA on both a consolidated basis and on a segment basis. We use Adjusted EBITDA to assess our financial performance because it allows us to compare our operating performance on a consistent basis across periods by removing the effects of our capital structure (such as varying levels of interest expense), asset base (such as depreciation and amortization) and items outside the control of our management team (such as income tax rates). Adjusted EBITDA has limitations as an analytical tool and should not be considered as an alternative to net income, operating income, cash flow from operating activities or any other measure of financial performance or liquidity presented in accordance with generally accepted accounting principles in the U.S. ("GAAP"). Our CODM uses Adjusted EBITDA as the primary measure of segment reporting performance.
