Stock-Based Compensation	STOCK-BASED COMPENSATION We compensate our officers, directors and employees with stock-based compensation under the 2017 Stock Incentive Plan (the 2017 Plan) approved by our shareholders and administered under the supervision of our Board of Directors. As of March 31, 2018, a total of 1,588 shares were available for issuance under the 2017 Plan. We make an annual stock grant under the 2017 Plan of stock options, restricted stock units and performance restricted stock units, as well as stock grants throughout the fiscal year. For fiscal years 2018, 2017 and 2016, the annual stock grant occurred in April 2018, April 2017 and December 2015, respectively. In fiscal year 2018, we adopted ASU No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. See Note 2 for additional information regarding the impact of adoption. Stock Options There were no stock options granted during the six months ended March 31, 2018 and April 1, 2017. Restricted Stock Units and Performance Restricted Stock Units We award restricted stock units to directors and key employees and performance restricted stock units to key employees. During the six months ended March 31, 2018 and April 1, 2017, we granted approximately 24 restricted stock units to officers and employees and 2 restricted stock units to employees, respectively. The fair value of the restricted stock units granted during the six months ended March 31, 2018 and April 1, 2017 was $48.61 and $47.73, respectively, representing the market value of our shares at the date of grant less the present value of estimated foregone dividends over the vesting period.
