Benefit Plans

The Company has an unfunded, nonqualified defined benefit plan (“Pension Plan”) for its officers. The Pension Plan is noncontributory and provides benefits based on years of service and compensation during employment. The Company determines pension expense using an actuarial cost method to estimate the total benefits ultimately payable to officers and allocates this cost to service periods. The actuarial assumptions used to calculate pension costs are reviewed annually. The Company contributed $1.3 million and $2.6 million to the Pension Plan during the three and six months ended August 4, 2018, respectively, and expects to make additional contributions to the Pension Plan of approximately $2.5 million during the remainder of fiscal 2018.

The components of net periodic benefit costs are as follows (in thousands):
