Actual results could differ from such estimates. Management estimates include determining the estimated lives of long-lived assets, determining the fair value of assets acquired and liabilities assumed in business combinations, the valuation of stock-based compensation awards, income tax expense, the valuation of deferred tax assets and liabilities, the fair value of derivative instruments, the value of contingent consideration and assessing its litigation, other legal claims and contingencies. Estimates and assumptions are reviewed periodically and the effects of revisions are reflected in the consolidated financial statements in the period that they are determined to be necessary.</p> <p style="font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:36pt;"/>
