1 Use of Non-GAAP Financial Measures Forward-looking statement This presentation contains forward-looking statements or information which reflect our expectations regarding possible events, conditions, our future growth, results of operations, performance, and business prospects and opportunities. All statements, other than statements of historical fact, are forward-looking statements. Forward-looking statements necessarily involve significant known and unknown risks, assumptions and uncertainties that may cause our actual results in future periods to differ materially from those expressed or implied by such forward-looking statements. These risks are described in our 2011 Form 10-K, and our other filings with the U.S. Securities and Exchange Commission and with the Canadian Securities Administrators. Accordingly, you are cautioned not to place undue reliance on forward-looking statements. These forward-looking statements are made as of the date hereof, and except as required by law, we assume no obligation to update or revise them to reflect new events or circumstances. These slides contain references to the following non-GAAP measures: (1) “Adjusted EBITDA” which is income (loss) before discontinued operations before repositioning expenses, interest expense, foreign exchange losses reclassified from other comprehensive income (loss), refinancing expenses, acquisition and related costs, gains and losses on sale of capital assets, gain on extinguishment of debt, income taxes, asset impairment charges, depreciation and amortization and other income and expenses; (2) “Adjusted EBITDA Margin which is adjusted EBITDA as a percentage of revenue; and (3) “Adjusted EBITDA Excluding Certain Items,” which is “Adjusted EBITDA” excluding the consulting fees associated with the strategic initiatives. Since Adjusted EBITDA, Adjusted EBITDA Margin, and Adjusted EBITDA before certain items are non-GAAP measures that do not have a standardized meaning, they may not be comparable to similar measures presented by other issuers. You are cautioned that these non-GAAP measures should not be substituted for their comparable GAAP measures as indicators of performance. We have included these measures because we believe that this information is used by certain investors to assess our financial performance, before non-cash charges and certain costs that we do not believe are reflective of our underlying business. In addition, Adjusted EBITDA is used by management as an internal measure of profitability. Reconciliations of Adjusted EBITDA and Adjusted EBITDA before certain items to the closest U.S. GAAP measures are included in the Appendix to this presentation. |
