The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and judgments that affect our reported financial position and results of operations. We review significant estimates and judgments affecting our consolidated financial statements on a recurring basis and record the effect of any necessary adjustments prior to their publication. Estimates and judgments are based on information available at the time such estimates and judgments are made. Adjustments made with respect to the use of these estimates and judgments often relate to information not previously available. Uncertainties with respect to such estimates and judgments are inherent in the preparation of financial statements. Estimates and judgments are used in, among other things, (1) aspects of revenue recognition, (2) valuation of acquisition related tangible and intangible assets and assessments of all long-lived assets for possible impairment, (3) estimating various factors used to accrue liabilities for workers’ compensation, auto, medical and general liability, (4) establishing an allowance for uncollectible accounts receivable, (5) estimating the useful lives of our assets, (6) assessing future tax exposure and the realization of tax assets, (7) estimating the value associated with contingent consideration payment arrangements, (8) the valuation of the embedded derivative liability in our convertible debt and (9) selecting assumptions used in the measurement of costs and liabilities associated with defined benefit pension plans. Our most significant accounting policies are described below. </font></div></div>
