37 Definitions Adjusted EBITDA represents earnings before interest, loss (gain) on extinguishment of debt, taxes, depreciation and amortization (“EBITDA”), adjusted for impairments, coal rationalization costs, changes to our contingent consideration liability related to our acquisition of CMT and the expiration of certain acquired contractual obligations. EBITDA and Adjusted EBITDA do not represent and should not be considered alternatives to net income or operating income under GAAP and may not be comparable to other similarly titled measures in other businesses. Management believes Adjusted EBITDA is an important measure of the operating performance and liquidity of the Company's net assets and its ability to incur and service debt, fund capital expenditures and make distributions. Adjusted EBITDA provides useful information to investors because it highlights trends in our business that may not otherwise be apparent when relying solely on GAAP measures and because it eliminates items that have less bearing on our operating performance and liquidity. EBITDA and Adjusted EBITDA are not measures calculated in accordance with GAAP, and they should not be considered a substitute for net income, operating cash flow or any other measure of financial performance presented in accordance with GAAP. EBITDA represents earnings before interest, taxes, depreciation and amortization. Adjusted EBITDA attributable to SXC/SXCP represents Adjusted EBITDA less Adjusted EBITDA attributable to noncontrolling interests. Adjusted EBITDA/Ton represents Adjusted EBITDA divided by tons sold/handled.37 Definitions Adjusted EBITDA represents earnings before interest, loss (gain) on extinguishment of debt, taxes, depreciation and amortization (“EBITDA”), adjusted for impairments, coal rationalization costs, changes to our contingent consideration liability related to our acquisition of CMT and the expiration of certain acquired contractual obligations.
