Reasons for Presentation of Non-GAAP Financial Measures Statements in this release include non-GAAP financial measures. Such information is provided as additional information, not as an alternative to our consolidated financial statements presented in accordance with GAAP, and is intended to enhance an overall understanding of our current financial performance. Such measures also are used to determine a portion of the compensation for some of our executives and employees. We believe the non-GAAP financial measures provide useful information to management, investors and prospective investors by excluding certain charges and other amounts that we believe are not indicative of our core operating results. These non-GAAP measures are included to provide management, our investors and prospective investors with an alternative method for assessing our operating results in a manner that is focused on the performance of our ongoing operations and to provide a more consistent basis for comparison between quarters. One of the non-GAAP financial measures presented is EBITDA (earnings before interest, taxes, depreciation, and amortization of identifiable intangible assets), other terms include Adjusted EBITDA (EBITDA plus equity-based compensation expense, impairment charges, write-off of loan fees, acquisition-related expenses and strategic planning costs) and Non-GAAP Income from Continuing Operations (Income from continuing operations, plus acquisition-related expenses, deferred financing fees written-off and strategic planning costs, net of tax) and Adjusted Income from Continuing Operations and related per share amounts. These terms might not be calculated in the same manner as, and thus might not be comparable to, similarly titled measures reported by other companies. The financial statement tables that accompany this press release include reconciliation of each non-GAAP financial measure to the most directly comparable GAAP financial measure.
