Appendix A – Reconciliation of GAAP Measures Calculation of EBITDA (1): (1) EBITDA represents earnings before interest, income taxes, depreciation and amortization. Management believes that EBITDA is a meaningful measure of the Company's operating performance, cash generation and ability to service debt. However, EBITDA should not be considered as an alternative to: (i) net earnings (determined in accordance with United States generally accepted accounting principles ("GAAP")); (ii) operating cash flow (determined in accordance with GAAP); or (iii) liquidity. Management also believes that EBITDA is sometimes useful to compare the operating results of companies within an industry due to the fact that it eliminates the effects of certain financing and accounting decisions. The Company's calculation of EBITDA may differ from similarly titled items reported by other companies.
