Employee Benefit Plans

6.   Employee Benefit Plans

The Company has a qualified 401(k) profit sharing plan available to full-time employees who meet the plan's eligibility requirements. This defined contribution plan permits employees to make contributions up to maximum limits allowed by the Internal Revenue Code of 1986 (the "Code"). The Company, at its discretion, matches a portion of the employee's contribution under a predetermined formula based on the level of contribution and years of service.  For 2011, the Company made matching contributions of 50% (25% in cash and 25% in Company stock) of the first 6% of eligible compensation deferred by the participant.  The Company recognized $3.2 million, $2.5 million, and $2.6 million of expense for the matching cash and Company stock contribution in 2011, 2010, and 2009, respectively.  All matching contributions vest over a three year period of service.

The Company has a deferred compensation plan for officers, directors, and certain sales personnel. The plan is designed to allow eligible participants to accumulate additional income through a nonqualified deferred compensation plan that enables them to make elective deferrals of compensation to which they will become entitled in the future. As of December 31, 2011, the deferred compensation liability balance was $1.6 million compared to $1.5 million as of December 31, 2010.
