Significant estimates and assumptions include the valuation of allowances for uncollectible receivables, inventory reserves, warranty reserves, stock-based compensation, evaluation of goodwill, plant and equipment for impairment, and determination of useful lives of long-lived assets. Actual results could materially differ from those estimates.</font></div><div style="line-height:120%;padding-bottom:0px;padding-top:0px;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Reclassifications</font></div><div style="line-height:120%;padding-bottom:8px;padding-top:8px;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Certain amounts recorded in the prior-period consolidated financial statements presented have been reclassified to conform to the current-period financial statement presentation.
