Judgments related to asset impairment and certain reserves are particularly subject to change. Actual results could differ from those estimates. Such estimates include, but are not limited to, allowance for doubtful accounts, reserve for sales discounts, estimated realizable value on obsolete and slow-moving inventory, warranty reserve, estimates related to pension accounting, estimates related to fair value for purposes of assessing goodwill, long-lived assets and intangible assets for impairment, estimates related to income taxes, and estimates related to contingencies.</span></div>
