Areas requiring significant use of management estimates relate to goodwill and intangibles, accruals for self-insured medical claims, workers’ compensation, legal contingencies, general liability and auto insurance claims, valuation of long-lived assets, and estimates of income taxes. Other areas requiring use of management estimates relate to allowance for doubtful accounts, inventory allowances, marketing program accruals, warranty accruals, and useful lives for depreciation and amortization. Actual results could differ from those estimates.</span></div>
