25 Appendix A – EBITDA Reconciliation

EBITDA represents earnings (loss) before income taxes, interest expense, depreciation and amortization and is an approximation of cash flow from operations before tax. The Company uses EBITDA as an internal measure of performance and believes it is a useful and commonly used measure of financial performance in addition to earnings (loss) before taxes and other profitability measures under generally accepted accounting principles (GAAP).

EBITDA is not a measure of performance under GAAP. EBITDA should not be construed as an alternative to operating income and earnings (loss) before taxes as an indicator of the company’s operations in accordance with GAAP. Nor is EBITDA an alternative to cash flow from operating activities in accordance with GAAP. The Company’s definition of EBITDA can differ from that of other companies.

The following table reconciles net earnings, the most comparable measure under GAAP, to EBITDA for the stated periods (in thousands).
