Reconciliation of EBITDA

“EBITDA” is defined as net income (loss) plus interest expense, income taxes, and depreciation and amortization including goodwill impairment charges. EBITDA is not a calculation based on generally accepted accounting principles. The amounts included in the EBITDA calculation, however, are derived from amounts included in the historical statements of operations data. In addition, EBITDA should not be considered as an alternative to net income or operating income as an indicator of our operating performance, or as an alternative to operating cash flows as a measure of liquidity. We have reported EBITDA because we regularly review EBITDA as a measure of our ability to incur and service debt. In addition, we believe our debt holders utilize and analyze our EBITDA for similar purposes. We also believe EBITDA assists investors in comparing a company’s performance on a consistent basis without regard to depreciation and amortization, which can vary significantly depending upon many factors. However, the EBITDA measure presented in this press release may not always be comparable to similarly titled measures by other companies due to differences in the components of the calculation.
