Retirement Savings Plan [Abstract]
RETIREMENT SAVINGS PLAN	15. RETIREMENT SAVINGS PLAN The Company maintains a defined contribution plan (the “Retirement Savings Plan”) pursuant to Section 401 of the Internal Revenue Code (the “Code”) which covers active regular employees. Employees are eligible under the Retirement Savings Plan immediately upon hire, and pre-tax contributions are allowed up to the limits set by the Code. In years prior to 2011, the Company made discretionary retirement savings contributions into the Retirement Savings Plan for certain eligible active regular employees based on an annual, discretionary percentage as determined by the Compensation, Nominating and Governance Committee of the Board of Directors. Beginning in 2011, the Company changed to a match program of up to 3% of an employee’s eligible pre-tax Retirement Savings Plan contributions up to certain Code limits, rather than an annual discretionary contribution. Employees vest in Company contributions over a three-year period. The Company may change this percentage at its discretion, and, in addition, the Company could decide to make additional or replacement discretionary contributions in the future. The Company contributed approximately $748,000, $1.2 million and $1.4 million to the Retirement Savings Plan for the 2011, 2010 and 2009 plan years, respectively.
