Our significant estimates and assumptions include, among others, pension and other post-retirement benefit plan assumptions, valuation assumptions of goodwill and other intangible assets, useful lives of long-lived assets, marketing and trade promotion accruals and income taxes. These estimates and assumptions are based on management’s best judgment. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, and the effects of any revisions are reflected in the consolidated financial statements in the period that they are determined. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates.</span></div>
