[1] The statement of earnings classification of amounts reclassified to net earnings include: 1. Pension liability adjustment – During August 2022, we purchased (using pension plan assets) an annuity contract from a third-party insurance company to transfer approximately 31% of the total projected benefit obligation of The Gerstenslager Company Bargaining Unit Employees’ Pension Plan as of the purchase date. As a result of this transaction: 1) we incurred a non-cash settlement charge of $4,774,000 within “Miscellaneous income (expense), net”; 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 Q – Derivative Financial Instruments and Hedging Activities”.
