* Non-GAAP Reconciliations *

* Non-GAAP Reconciliations ($ in millions) We calculate Adjusted EBITDA from continuing operations as earnings before net interest expense and other, taxes, depreciation and amortization. Adjusted EBITDAX is Adjusted EBITDA from continuing operations plus the earnings of our former oil and gas business before net interest expense and other, taxes, depreciation and amortization, and exploration expense. These non-GAAP measures are useful to investors and other internal and external users of our financial statements in evaluating our operating performance; they are widely used by investors in our industry to measure a company’s operating performance without regard to items which can vary substantially from company to company, and help investors meaningfully compare our results from period to period. Adjusted EBITDA from continuing operations and Adjusted EBITDAX should not be considered in isolation or as a substitute for, but instead is supplemental to, income from operations, net income and other income data prepared in accordance with GAAP. Non-GAAP financial measures should be viewed in addition to, and not as an alternative to our reported results prepared in accordance with GAAP. Users of this financial information should consider the types of events and transactions which are excluded from this measure.
