EMPLOYEE BENEFIT PLANS	(10) EMPLOYEE BENEFIT PLANS We maintain a defined contribution retirement plan in accordance with Section 401(k) of the Internal Revenue Code, which allows eligible participating employees to defer receipt of up to 50% of their annual compensation and contribute such amount to one or more investment funds. We match employee contributions in a discretionary amount to be determined by management each plan year up to the lesser of 6% of an employee’s annual compensation or $3,000 per participant.

Company matching funds and discretionary contributions vest at the rate of 20% each year beginning after the participants’ first year of service. We did not make a contribution in 2011. We contributed approximately $1.0 million in 2010 and $1.0 million in 2009.
