Retirement Benefits We sponsor a 401(k) savings plan providing benefits for substantially all United States based employees of both 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 $2,612, $2,463 and $2,382 to the plan for fiscal years 2018, 2017, and 2016, respectively.
