The Company evaluates the performance of its reportable segments based upon revenue and measures of profit or loss referred to as EBITDA and Adjusted EBITDA. The Company defines Adjusted EBITDA as earnings from continuing operations before interest and taxes (EBIT), adjusted for depreciation and amortization (EBITDA), and then further adjusted for unusual and other significant items that management views as distorting the operating results of the various segments from period to period. Such adjustments include restructuring charges, stock-based compensation, bargain purchase gains, acquisition-related charges and benefits (acquisition transaction costs, acquisition obligations classified as compensation, and fair value adjustments to acquisition-related contingent consideration), tangible and intangible asset impairment charges, certain litigation costs and litigation settlements, certain severance charges and foreign currency transaction gains and losses on short-term intercompany balances viewed by management as individually or collectively significant. The Company does not have any inter-segment revenue.
