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, manufactures 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. The operating results of the Tubular Sales component that was sold in June 2013 have been accounted for as discontinued operations and have been excluded from the segment results below. Adjusted EBITDA We define Adjusted EBITDA as income 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, stock-based compensation, 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. The following table presents a reconciliation of Segment Adjusted EBITDA to income from continuing operations (in thousands): Year Ended December 31, 2015 2014 2013 Segment Adjusted EBITDA: International Services $ 182,475 $ 231,469 $ 199,620 U.S. Services 93,871 180,575 198,442 Tubular Sales 40,999 38,366 40,624 Total 317,345 450,410 438,686 Corporate and other 96 (34 ) 53 Adjusted EBITDA Total 317,441 450,376 438,739 Interest income (expense), net 341 87 (653 ) Income tax expense (37,319 ) (75,412 ) (38,727 ) Depreciation and amortization (108,962 ) (90,041 ) (78,082 ) Gain on sale of assets 1,038 (289 ) 122 Foreign currency loss (6,358 ) (17,041 ) (2,556 ) Stock-based compensation expense (26,119 ) (38,368 ) (7,220 ) Severance and other costs (35,484 ) — — Change in value of contingent consideration 1,532 — — IPO transaction-related costs (1) — — (3,428 ) Income from continuing operations $ 106,110 $ 229,312 $ 308,195 (1) Represents charges incurred in connection with our IPO, primarily those amounts attributable to the restructuring in advance of the IPO.

We are a Netherlands based company and we derive our revenue from services and product sales to clients primarily in the oil and gas industry. No single customer accounted for more than 10% of our revenue for the years ended December 31, 2015 , 2014 and 2013 .

Other than the United States and Dubai, which had revenues of $ 140.4 million , no individual country represented more than 10% of our revenue for the year ended December 31, 2015 . Other than the United States, no individual country represented more than 10% of our revenue for each of the years ended December 31, 2014 and 2013 .
