The Company believes Adjusted EBITDAX assists management and investors in comparing the Company's performance and ability to fund capital expenditures and working capital requirements on a consistent basis without regard to depreciation, depletion and amortization, impairment of natural gas and oil properties and exploration expenses, which can vary significantly from period to period. In addition, management uses Adjusted EBITDAX as a financial measure to evaluate the Company's operating performance. Adjusted EBITDAX is also widely used by investors and rating agencies.Adjusted EBITDAX is not a measure of financial performance under GAAP. Accordingly, it should not be considered as a substitute for net income, income from operations, or cash flow provided by operating activities prepared in accordance with GAAP. Information regarding income taxes, interest, depreciation, depletion, amortization, impairment, abandonment, and exploration expense is unavailable on a forward looking basis. Net income, income from operations, or cash flow provided by operating activities may vary materially from Adjusted EBITDAX. Investors should carefully consider the specific items included in the computation of Adjusted EBITDAX. The Company has disclosed Adjusted EBITDAX to permit a comparative analysis of its operating performance and debt servicing ability relative to other companies.
