Employee Benefit Plans

Note 17.  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, 2012, 2011 and 2010, we matched 50 percent 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. We recognized expense associated with matching contributions as follows (in thousands):
