Non-GAAP Financial Measures

EBITDA and adjusted EBITDA are supplemental non-GAAP financial measures that are used by management and external users of our financial statements, such as industry analysts, investors, lenders and rating agencies. We define "EBITDA" as earnings (or loss) before interest, taxes, depreciation, and amortization, and we define "Adjusted EBITDA" as EBITDA before stock-based compensation, acquisition transaction related expenses, debt extinguishment expenses and other non-recurring items. Neither EBITDA nor Adjusted EBITDA is a measure of net income as determined by U.S. generally accepted accounting principles ("GAAP").

Management believes EBITDA and Adjusted EBITDA are useful because they allow management to more effectively evaluate our operating performance and compare the results of our operations from period to period and against our peers without regard to our financing methods or capital structure or non-recurring, non-cash transactions. We exclude the items listed above in calculating EBITDA and Adjusted EBITDA because these amounts can vary substantially from company to company depending upon capital structures and the method by which assets were acquired. None of EBITDA or Adjusted EBITDA should be considered an alternative to, or more meaningful than, net income (loss), the most closely comparable financial measure calculated in accordance with GAAP. Certain items excluded from EBITDA and Adjusted EBITDA are significant components in understanding and assessing a company's financial performance, such as a company's return on assets, cost of capital and tax structure. Our presentation EBITDA and Adjusted EBITDA should not be construed as an inference that our results will be unaffected by unusual or non-recurring items. Our computations of EBITDA and Adjusted EBITDA may not be comparable to other similarly titled measures of other companies.
