Defined Benefit Plan [Abstract] |
Retirement Plans | Retirement Benefit Plans We have two frozen noncontributory defined benefit plans: our pension plan (the “pension plan”) and our unfunded, nonqualified plan (the “restoration plan”), which restores retirement benefits for certain associates who are affected by Internal Revenue Code limitations on benefits provided under the pension plan. No additional benefits have accrued under these plans since they were frozen; however, we have a continuing obligation to fund the pension plan and will continue to recognize net periodic pension expense for both plans for benefits earned prior to being frozen. We use a fiscal year end measurement date for both the pension plan and the restoration plan. Net Pension Expense

Net pension expense includes actuarial loss amortization of $0.5 million and $0.4 million for the three months ended August 31, 2017 and 2016, respectively and $0.9 million and $0.8 million for the six months ended August 31, 2017 and 2016, respectively. We made no contributions to the pension plan during the six months ended August 31, 2017. Subsequent to the end of the quarter, we made a $6.0 million contribution to the pension plan. We do no t expect to make any additional contributions during the remainder of fiscal 2018. The expected long-term rate of return on plan assets for the pension plan was 7.75% as of February 28, 2017.
