6. Stock Based Compensation

At our 2018 annual meeting of stockholders held on May 17, 2018, our stockholders approved the Floor & Decor Holdings, Inc. Employee Stock Purchase Plan (the “ESPP”), which became available to substantially all of our employees beginning in the third quarter of fiscal 2018. The ESPP permits eligible employees to purchase shares of our common stock through payroll deductions, subject to certain limitations. The purchase price of the shares under the ESPP in no event will be less than the lesser of 85% of the lower of the fair market value of our common stock on either the first or last trading day of each six-month offering period. There were 1,500,000 shares of our Class A common stock, par value $0.001 per share, approved for issuance. On December 31, 2018, $1.4 million in contributions were used to purchase 60,871 shares of our Class A common stock. Additionally, during the thirteen weeks ended March 28, 2019, the Company recognized $143 thousand of stock-based compensation expense related to the ESPP.
