Non-GAAP Financial Measures

EBITDAX, Adjusted net income (loss) and Adjusted net income (loss) per share are supplemental non-GAAP financial measures used by management and external users of the Company's consolidated financial statements, such as industry analysts, investors, lenders and rating agencies. The Company defines EBITDAX as net income (loss) plus (i) exploration expense, (ii) depletion, depreciation and amortization expense, (iii) equity‑based compensation expense, (iv) unrealized (gain) loss on commodity derivatives (realized losses are deducted and realized gains are added back), (v) (gain) loss on sale of oil and gas properties, (vi) interest (income) expense, (vii) income taxes, (viii) loss on extinguishment of debt, (ix) doubtful accounts expense and (x) similar other material items which management believes affect the comparability of operating results. The Facility EBITDAX definition includes 50% of the EBITDAX adjustments of Kosmos-Trident International Petroleum Inc. The Company defines adjusted net income (loss) as net income (loss) after adjusting for the impact of certain non-cash and non-recurring items, including non-cash changes in the fair value of derivative instruments, cash settlements on commodity derivatives, gain on sale of assets, and other similar non-cash and non-recurring charges, and then the non-cash and related tax impacts in the same period.

We believe that EBITDAX, Adjusted net income (loss), and Adjusted net income (loss) per share and other similar measures are useful to investors because they are frequently used by securities analysts, investors and other interested parties in the evaluation of companies in the oil and gas sector and will provide investors with a useful tool for assessing the comparability between periods, among securities analysts, as well as company by company. Because EBITDAX, Adjusted net income (loss), and Adjusted net income (loss) per share excludes some, but not all, items that affect net income, these measures as presented by us may not be comparable to similarly titled measures of other companies.
