Retirement Benefits	Note 13. Retirement Benefits We sponsor a 401(k) savings plan providing benefits for substantially all United States-based employees of Daktronics, Inc. and its subsidiaries, subject to certain Internal Revenue Service ("IRS") limits. We make matching cash contributions equal to 50 percent of the employee's qualifying contribution up to six percent of such employee's compensation. Employees are eligible to participate upon completion of three months of continuous service if they have attained the age of 21. We contributed $2,754, $2,612 and $2,463 for matches to the plan for fiscal years 2019, 2018, and 2017, respectively.
