Non-GAAP Measure

Free cash flow is a non-GAAP measure mentioned above that we use as an indicator of our ability to either fund our development activities or reduce outstanding borrowings. We define free cash flow as Adjusted EBITDAX, less interest expense, less accrual-based capital expenditures. We define Adjusted EBITDAX as net income (loss) plus, when applicable, accretion of asset retirement obligations; impairment expense; depletion, depreciation and amortization; interest expense, net; transaction costs; (gain) loss on sale of oil and gas properties, net; exploration expense; unrealized (gain) loss on derivative contracts; stock-based compensation (non-cash); and income tax expense (benefit).
