Employer Contributions Total contributions to be made during fiscal 2017, will depend primarily on market returns on the pension plan assets and minimum funding level requirements. During the three months ended November 30, 2016, we made no contributions to the pension plans. At this time, we do not anticipate having to make a required contribution for our benefit plans in fiscal 2017, but we may make a voluntary contribution during the fourth quarter of fiscal 2017.
