Effective July 2004, we began sponsoring a 401(k) retirement plan covering substantially all employees who meet certain eligibility requirements. Employees may contribute elective deferrals to the plan up to amounts allowed under the Internal Revenue Code. We are not required to contribute to the plan but may make discretionary profit sharing and matching contributions. During our fiscal years 2017 and 2016, we made discretionary contributions of $47,000 and $43,000, respectively.
