401(k) Savings Plan

7. 401(k) Savings Plan

We have a 401(k) Retirement Savings Plan for the benefit of our eligible employees. All staffing and management employees 21 years of age or older become eligible to participate in the savings plan upon completion of 1,000 hours of service in a consecutive 12-month period following the initial date of employment. Employees covered under a PEO arrangement may participate in the plan at the sole discretion of the PEO client. The determination of discretionary Company contributions to the plan, if any, is at the sole discretion of our Board of Directors. No discretionary Company contributions were made to the plan for the years ended December 31, 2016, 2015 and 2014.

We make matching contributions to the 401(k) plan under a safe harbor provision, whereby the Company matches 100% of contributions by management and staffing employees up to 3% of each participating employee's annual compensation; and 50% of the employee's contributions up to an additional 2% of annual compensation. We made $1,402,000, $1,158,000, and $885,000 of matching contributions during 2016, 2015 and 2014, respectively. Participants' interests in Company safe harbor contributions to the plan are fully vested when payments are made.
