Employer Contributions

Any contributions made during fiscal 2020 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 nine months ended May 31, 2020, and we do not currently anticipate being required to make contributions for our pension plans in fiscal 2020.
