NON-GAAP FINANCIAL MEASURES We present our operating results in accordance with accounting principles generally accepted in the U.S. (“U.S. GAAP”). We believe certain financial measures, such as EBITDA, Adjusted EBITDA, Adjusted Net Income and Free Cash Flow, which are non-GAAP measures, provide users of our financial statements with supplemental information that may be useful in evaluating our operating performance. We believe that such non-GAAP measures, when read in conjunction with our operating results presented under U.S. GAAP, can be used to better assess our performance from period to period and relative to performance of other companies in our industry, without regard to financing methods, historical cost basis or capital structure. Such non-GAAP measures should be considered as a supplement to, and not as a substitute for, financial measures prepared in accordance with U.S. GAAP. All non-GAAP measure reconciliations to the most comparative U.S. GAAP measures are displayed in quantitative schedules on the company’s website at: www.deepwater.com.
