EBITDA and Free Cash Flow

EBITDA means earnings before interest, income taxes, depreciation and amortization, while free cash flow means cash flow from operating activities less capital expenditures plus the excess tax benefit from stock-based compensation. Management uses these non-GAAP financial measures as internal operating metrics and for enterprise valuation purposes. Management believes these measures are useful as analytical indicators of leverage capacity and debt servicing ability, and uses them to measure financial performance as well as for planning purposes. However, they should not be considered as alternatives to net income, cash flow from operating activities or any other items calculated in accordance with U.S. GAAP, or as an indicator of operating performance. The definitions of EBITDA and free cash flow used here may differ from those used by other companies.
