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 billing adjustments and uncollectible accounts receivable, the reserve for obsolete, excess and damaged inventory, the life of its rented equipment, valuation of stock-based compensation, and valuation of long-lived assets and realizability of deferred tax assets.</div> </div><table border="0" style="width:100%; table-layout:fixed;" cellspacing="0" cellpadding="0"><tr><td></td></tr></table>
