Appendix Non-GAAP supplemental information

Annual EBITDA and FCF reconciliation * Adjusted for FASB Staff Position APB 14-1, "Accounting for Convertible Debt Instruments That May be Settled in Cash Upon Conversion (Including Partial Cash Settlement)", which changed the method of accounting for our convertible notes. Note: This information provides a reconciliation of EBITA/EBITDA/Adjusted EBITDA to the financial information in our consolidated statements of operations "EBITDA" means earnings before interest expense, income taxes, depreciation and amortization. "EBITA" means earnings before interest expense, income taxes and amortization. We present EBITDA / EBITA / Adjusted EBITDA to enhance the understanding of our operating results. EBITDA / EBITA / Adjusted EBITDA is a key measure we use to evaluate our operations. In addition, we provide our EBITDA / EBITA / Adjusted EBITDA because we believe that investors and securities analysts will find EBITDA / EBITA / Adjusted EBITDA to be a useful measure for evaluating our operating performance and comparing our operating performance with that of similar companies that have different capital structures and for evaluating our ability to meet our future debt service, capital expenditures, and working capital requirements. However, EBITDA / EBITA / Adjusted EBITDA should not be considered as an alternative to cash flows from operating activities as a measure of liquidity or as an alternative to net income as a measure of operating results in accordance with accounting principles generally accepted in the United States of America.
