Use of non-GAAP financial measures

Adjusted EBITDA is not a recognized accounting measurement under GAAP; it should not be considered as an alternative to net income, as a measure of operating results, or as an alternative to cash flow as a measure of liquidity. It is presented here not as an alternative to net income, but rather as a measure of the Company's operating performance. Since EBITDA (generally, net income plus interest expense, taxes, depreciation and amortization) is not calculated identically by all companies, the presentation in this report may not be comparable to EBITDA or Adjusted EBITDA presentations disclosed by other companies. Adjusted EBITDA is calculated above and represents for any relevant period, net income/(loss) plus depreciation and amortization, restructuring, acquisition and integration costs, goodwill and long-lived asset impairment, change in fair value of contingent consideration, interest expense, income tax provision, other income/(expense) and equity in net (income)/loss of unconsolidated subsidiary. Management believes that Adjusted EBITDA is useful in evaluating the Company's operating performance compared to that of other companies in its industry because the calculation of Adjusted EBITDA generally eliminates the effects of financing, income taxes and certain non-cash and other items that may vary for different companies for reasons unrelated to overall operating performance. The Company’s management uses Adjusted EBITDA as a measure to evaluate performance and for other discretionary purposes.
