Defined Contribution Pension and Other Postretirement Plans Disclosure [Abstract]
Defined Contribution Plans	Defined Contribution Plans Prior to 2006, the Company had various savings plans (the "Savings Plans") that qualified as defined contribution plans under Section 401(k) of the Internal Revenue Code. In 2006, the Savings Plans were consolidated into one savings plan (the "Master Savings Plan"), which also qualifies as a defined contribution plan under Section 401(k) of the Internal Revenue Code. Under the Master Savings Plan, participating employees may defer a percentage of their eligible pre-tax earnings up to the Internal Revenue Service's annual contribution limit. All full-time domestic employees of the Company are eligible to participate in the Master Savings Plan. The Master Savings Plan does not permit investment of participant contributions in the Company's common stock. Company matching contributions to the Master Savings Plan is discretionary. Company contributions to the Master Savings Plan amounted to $883,000, $738,000 and $734,000 for the years ended December 31, 2011, 2010 and 2009, respectively.
