Employee Benefit Plans

We sponsor a defined contribution 401(k) plan for all employees 18 years or older. Employee contributions may be made on a before-tax basis, limited by IRS regulations. For the years ended December 31, 2015, 2014 and 2013, we matched 50% of the employee’s contributions up to 6% of eligible compensation. Eligibility for the matching contribution in all years began after the participant had worked a minimum of three months. Our matching contributions to the plan vest ratably over five years of service by the employee. During 2014, we used approximately $165,000 of previously forfeited matching contributions to fund current matching contributions, which decreased our 2014 expense. We recognized expense associated with matching contributions as follows (in thousands):
