Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

Stock Options, Valuation Assumptions

The fair value of each option award is estimated on the date of grant using the Black-Scholes option valuation model that uses the assumptions noted in the following table.  The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant.  The expected life of options granted is based on the vesting period and historical exercise and post-vesting employment termination behavior for similar grants.  We use historical data to estimate option exercise and employee termination within the valuation model; separate groups of employees that have similar historical exercise behavior are considered separately for valuation purposes.

Weighted average Black -Scholes fair value assumption	2012				2011				2010
Risk free rate	0.98		%		2.09		%		1.22		%
Expected life	6 years				5 years				2 years
Expected volatility	62.37		%		64.89		%		64.32		%
Expected dividend yield	—				—				—
