Significant estimates include acquisition purchase price allocations, the fair value of goodwill and intangibles, the realization of deferred tax assets and liabilities, acquisition-related liabilities, fair value of stock-based compensation for stock options and performance share units granted, and assets and liabilities for pension and postretirement benefits.
