As of January 1, 2018, we adopted new accounting guidance on presentation of net periodic pension and postretirement benefit cost ("net benefit cost"). Under the new guidance, we are required to present non-service cost components of net benefit cost in interest and other expenses, as opposed to selling and administrative expenses. All previously reported results have been restated to conform to the current year presentation. (See Note 9 to the Consolidated Financial Statements for further information.)
