Appendix

Statement on Non-GAAP Financial Measures NON-GAAP FINANCIAL MEASURES AND OTHER ITEMS   In this presentation, we refer to various non-GAAP (U.S. generally accepted accounting principles) financial measures which management uses to evaluate operating performance, to establish internal budgets and targets, and to compare the Company's financial performance against such budgets and targets. These non-GAAP measures, as defined by the Company, may not be comparable to similarly titled measures being disclosed by other companies. While adjusted financial measures are not intended to replace any presentation included in our consolidated financial statements under generally accepted accounting principles (GAAP) and should not be considered an alternative to operating performance or an alternative to cash flow as a measure of liquidity, we believe these measures are useful to investors in assessing our operating results, capital expenditure and working capital requirements and the ongoing performance of its underlying businesses. A reconciliation of Adjusted GAAP financial measures is included with this presentation. All per share amounts are on a fully diluted basis. The quarterly amounts described below are unaudited, are reported in thousands of U.S. dollars, and are as of the dates indicated.
