Employee Benefit Plans

Note 17.  Employee Benefit Plans

We sponsor a defined contribution or 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, 2011 and 2010, we matched 50 percent of the employee's contributions up to 6% of eligible compensation. For the year ended December 31, 2009, we matched the employee's contribution up to 4% 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 of $687,000, $428,000 and $600,000 for the years ended December 31, 2011, 2010 and 2009, respectively.
