Benefit Plans

    We have various pension and other defined benefit and defined contribution plans, in which substantially all employees may participate. We also have nonqualified supplemental executive and Board retirement plans.

    Components of net periodic benefit costs for the three months ended November 30, 2021 and 2020, are as follows:

Employer Contributions

    Any contributions made during fiscal 2022 will depend primarily on market returns on the pension plan assets and minimum funding level requirements. No contributions were made to the pension plans during the three months ended November 30, 2021, and we do not currently anticipate being required to make contributions for our pension plans in fiscal 2022.
