Significant estimates include implicit price concessions, revenue estimates, the allowances for doubtful accounts, deferred tax assets, fair values of acquired assets and assumed liabilities in business combinations, fair value of goodwill and indefinite-lived intangible assets, amortization lives for acquired intangible assets, and accruals for self-insurance reserves, litigation reserves and pensions.
