Adjusted EBITDA Non-GAAP Financial Measures. Adjusted EBITDA is a non-GAAP supplemental financial measure. We define Adjusted EBITDA as net income (loss) adjusted by: (i) interest (income) expense, net which includes interest expense, interest expense net (gain) loss on interest rate derivative contracts, and interest (income); (ii) income tax expense (benefit); (iii) depreciation, depletion and amortization; (iv) asset impairments; (v) accretion expense; (vi) (gain) loss on sale of assets; (vii) unit-based compensation programs; (viii) unit-based management fees; (ix) distributions in excess of equity earnings; (x) (gain) loss on mark-to-market activities; (xi) commodity derivative settlements applied to future positions; and (xii) gain (loss) on embedded derivatives; and (xiii) acquisition and divestiture costs. Adjusted EBITDA is also used as a quantitative standard by our management and by external users of our financial statements such as investors, research analysts, our lenders and others to assess the financial performance of our assets without regard to financing methods, capital structure or historical cost basis; the ability of our assets to generate cash sufficient to pay interest costs and support our indebtedness; and our operating performance and return on capital as compared to those of other companies in our industry, without regard to financing or capital structure. Adjusted EBITDA is not intended to represent cash flows for the period, nor are they presented as a substitute for net income, operating income, cash flows from operating activities or any other measure of financial performance or liquidity presented in accordance with GAAP We are unable to reconcile our forecasted Adjusted EBITDA to forecasted GAAP net income (loss) or net cash flow provided by operating activities because it would take unreasonable efforts to predict the future impact of adjustments to (i) net income (loss) for unit based compensation and asset management fees, (gains) losses from mark-to-market activities and equity investments or asset impairments due to the difficulty of doing so, or (ii) net cash flow provided by operating activities because this metric includes the impact of changes in operating assets and liabilities related to the timing of cash receipts and disbursements that may not relate to the period in which the operating activities occurred. Additionally, we are unable to address the probable significance of the unavailable reconciliation, in significant part due to ranges in our forecast impacted by changes in oil and natural gas prices and reserves which affect certain reconciliation items. 23 Need reconciliation tables
