Page ? 4 (r) Non-GAAP Financial MeasuresFree Cash Flow: Free cash flow is a non-GAAP financial measure defined as cash flows from operations less capital expenditures. We consider free cash flow to be useful as an indicator of our overall liquidity, as the amount of free cash flow generated in any period is representative of cash that is available for strategic opportunities including, among others, investing in the Company's business, making strategic acquisitions, strengthening the balance sheet, repaying debt and repurchasing stock. We also believe that free cash flow is one of several benchmarks used by investors for comparison of our liquidity with other companies in our industry, although our measure of free cash flow may not be directly comparable to similar measures reported by other companies. Free cash flow should not be construed as an alternative to cash flows from operations or other cash flow measurements determined in accordance with GAAP. EBITDA: EBITDA is a non-GAAP financial measure defined as net income before interest, income tax expense, depreciation and amortization. We include information concerning EBITDA because we believe it is a useful measure to evaluate our operating performance. As a measure of our operating performance, we believe EBITDA provides a measure of operating results unaffected by differences in capital structures, capital investment cycles and ages of related assets among otherwise comparable companies. While EBITDA is a relevant and widely used measure of operating performance, it does not represent net income as defined by GAAP and it should not be considered as an alternative to that measure in evaluating operating performance.
