Employer Contributions

Total contributions to be made during fiscal 2019 will depend primarily on market returns on the pension plan assets and minimum funding level requirements. During the three months ended November 30, 2018, we made no contributions to the pension plans. At this time, we do not anticipate being required to make a contribution for our benefit plans in fiscal 2019.
