Actual results could differ from those estimates. The most significant management estimates used in the preparation of the accompanying consolidated financial statements are associated with the allowance for contractual adjustments and uncollectible accounts receivable, the reserve for obsolete and damaged inventory, stock-based compensation, valuation of goodwill and other long-lived assets, and income taxes. </p></div>
