Use of Non-GAAP Financial Measures

Commencing in fiscal 2013, the Company revised its calculation of Adjusted EBITDA to exclude stock-based compensation expense, consulting costs related to its operational initiatives, purchase accounting adjustments, and acquisition-related litigation expenses. The Company believes that excluding these items from Adjusted EBITDA better reflects the underlying performance. Based on the revisions to the definition of Adjusted EBITDA, the Company has recast the presentation of Adjusted EBITDA for the twelve months ended October 31, 2012, to be consistent with the current period presentation. Adjusted EBITDA is now income (loss) from continuing operations before repositioning expenses, interest expense, foreign exchange losses reclassified from other comprehensive income (loss), refinancing expenses, acquisition and integration costs (including certain product returns and inventory write-offs recorded in gross profit), gains and losses on sale of capital assets, income taxes, asset impairment charges, depreciation and amortization, stock-based compensation expense, consulting costs related to our operational initiatives, purchase accounting adjustments, acquisition-related litigation expenses and other income and expenses. Since Adjusted EBITDA is a non-GAAP measure that does not have a standardized meaning, it may not be comparable to similar measures presented by other issuers. Readers are cautioned that Adjusted EBITDA should not be construed as an alternative to net income (loss) determined in accordance with U.S. GAAP as an indicator of performance. Adjusted EBITDA is used by management as an internal measure of profitability. The Company has included Adjusted EBITDA because it believes that this measure is used by certain investors to assess the Company’s financial performance before non-cash charges and certain costs that the Company does not believe are reflective of its underlying business. A reconciliation of Adjusted EBITDA to the closest U.S. GAAP measure is included with the financial statements in this press release.
