EMPLOYEE BENEFIT PLANS

EMPLOYEE BENEFIT PLANS

We maintain a defined contribution retirement plan (the "Plan") in accordance with Section 401(k) of the Internal Revenue Code, which allows eligible participating employees to defer receipt of up to 50% of their annual compensation and contribute such amount to one or more investment funds. We match employee contributions in a discretionary amount to be determined by management and approved by the Board of Directors each plan year up to the lesser of 6% of an employee’s annual compensation or $3,000 per participant. We also may make additional discretionary contributions to the Plan as determined by management and approved by the Board of Directors each plan year. Company matching funds and discretionary contributions vest 100% after three years of service for participants who either had attained three or more years of service or were hired on or after January 1, 2012. For all other participants, company matching funds and discretionary contributions vest at the rate of 20% after two years of service and 100% after three years of service. We amended the Plan in 2013 to add Roth 401(k) plan features that allow participating employees to make post-tax contributions in addition to, or in lieu of, the pre-tax contributions allowed under the Plan. Company matching funds are made on a pre-tax basis for both pre-tax and post-tax employee contributions, and are subject to the above limitations based on the aggregate pre-tax and post-tax contribution by the participant. The Company contributed to the Plan approximately $0.8 million in 2016, $0.8 million in 2015, and $1.0 million in 2014.
