RECONCILIATION OF NON-GAAP FINANCIAL MEASURES

Adjusted EBITDA from Continuing Operations

Adjusted EBITDA from continuing operations is a supplemental non-GAAP financial measure that is used by management and external users of our financial statements, such as industry analysts, investors, lenders and rating agencies. We define Adjusted EBITDA from continuing operations as net income (loss) from continuing operations before depreciation, depletion, amortization and accretion, gains on disposal of assets, net, impairment of long lived assets, equity based compensation, stock based compensation, interest expense (income), net, (loss) gain on marketable securities, net, other (income) expense, net and provision for income taxes. We exclude the items listed above from net income (loss) from continuing operations in arriving at Adjusted EBITDA from continuing operations because these amounts can vary substantially from company to company within our industries depending upon accounting methods and book values of assets, capital structures and the method by which the assets were acquired. Adjusted EBITDA from continuing operations should not be considered as an alternative to, or more meaningful than, net income (loss) from continuing operations or cash flows from operating activities as determined in accordance with GAAP or as an indicator of our operating performance or liquidity. Certain items excluded from Adjusted EBITDA from continuing operations are significant components in understanding and assessing a company’s financial performance, such as a company’s cost of capital and tax structure, as well as the historical costs of depreciable assets, none of which are components of Adjusted EBITDA from continuing operations. Our computations of Adjusted EBITDA from continuing operations may not be comparable to other similarly titled measures of other companies. We believe that Adjusted EBITDA from continuing operations is a widely followed measure of operating performance and may also be used by investors to measure our ability to meet debt service requirements.

The following tables provide a reconciliation of Adjusted EBITDA from continuing operations to net income (loss) from continuing operations, the most directly comparable GAAP financial measure for the specified periods (in thousands):
