Employee Benefit Plans

(12) EMPLOYEE BENEFIT PLANS

We provide a defined contribution plan for the majority of our employees meeting minimum service requirements. The employees can contribute up to 30% of their current compensation to the plan subject to certain statutory limitations. We contribute up to a maximum of 3% of an employee’s compensation to the plan. We made contributions to the plan and charged operating results $4.3 million during 2014, $3.8 million during 2013, and $3.3 million during 2012.
