RETIREMENT AND STOCK PURCHASE PLANS
RETIREMENT AND STOCK PURCHASE PLANS	14. RETIREMENT AND STOCK PURCHASE PLANS We have 401(k) savings plans which allow eligible employees to save for retirement on a tax deferred basis. Employer matching contributions under the 401(k) savings plans are made based on a formula set by the Board from time to time. During fiscal 2017, 2016 and 2015, our matching contributions for the plans charged to operations were $2.7 million, $1.4 million and $1.2 million, respectively. We also maintain a noncontributory defined benefit pension plan and a post-retirement benefit plan which cover certain union and nonunion employees at Jos. A. Bank. The plans provide for eligible employees to receive benefits based principally on years of service. Amounts related to the defined benefit pension and post-retirement benefit plans were immaterial to our consolidated financial statements. In addition, we have an Employee Stock Discount Plan (“ESDP”) which allows employees to authorize after‑tax payroll deductions to be used for the purchase of up to 2,137,500 shares of our common stock at 85% of the lesser of the fair market value of our common stock on the first day of the offering period or the fair market value of our common stock on the last day of the offering period. We make no contributions to this plan but pay all brokerage, service and other costs incurred. A participant may not purchase more than 125 shares during any calendar quarter. During fiscal 2017, 2016 and 2015, employees purchased 167,673 shares, 167,237 shares and 87,537 shares, respectively, under the ESDP, the weighted‑average fair value of which was $10.74, $11.66 and $26.23 per share, respectively. We recognized approximately $0.6 million, $0.5 million and $0.7 million of share‑based compensation expense related to the ESDP for fiscal 2017, 2016 and 2015, respectively. As of February 3, 2018, 230,956 shares were reserved for future issuance under the ESDP.
