[1] The statement of earnings classification of amounts reclassified to net income include: (1) Pension liability adjustment – As disclosed in “Note M – Employee Pension Plans”, includes a reclassification adjustment of $4,774 related to the pension lift-out transaction to transfer a portion of the total projected benefit obligation of the Gerstenslager Company Bargaining Unit Employees’ Pension Plan to a third-party insurance company. As a result of this transaction: 1) we incurred a non-cash settlement charge of $4,774 recorded in miscellaneous income (expense), net in the consolidated statement of earnings; 2) we were relieved of all responsibility for these pension obligations; and 3) the insurance company is now required to pay and administer the retirement benefits owed to 220 beneficiaries; and (2) Cash flow hedges – disclosed in “Note R – Derivative Financial Instruments and Hedging Activities.”
