Retirement Plan [Abstract]

Retirement Plan

10. Retirement Plan

The Company maintains a retirement savings plan for all eligible employees, in which employees may make deferred salary contributions up to the maximum amount allowable by the IRS. After-tax contributions may also be made up to 50% of compensation. The Company makes matching contributions equal to 50% of the first 6% of both deferred and after-tax salary contributions, up to a maximum of $5,000, through April 1, 2009, at which time the matching contributions were suspended by the Company. During 2008 and 2009, any employee that was involuntarily terminated was vested at 100% in the Company’s matching contributions made through the termination date due to the 401(k) partial plan guidelines. Effective September 1, 2010, the Company reinstated the matching contributions with the same criteria in effect prior to its suspension. The Company’s contributions charged to expense for the plan were $1.4 million, $0.3 million, and $0.3 million for the years ended December 31, 2011, 2010 and 2009, respectively.
