Schedule of Share-based Payment Award, Stock Options, Valuation Assumptions [Table Text Block]

We generally use the Black-Scholes option-pricing model to calculate the grant-date fair value of stock options granted to employees under our stock incentive plans. We calculated the fair value for options granted during 2013, 2012 and 2011 using the following estimated weighted-average assumptions:

	Year Ended December 31,
	2013			2012			2011
Options granted (in thousands)	1,992			4,726			16,311
Weighted-average exercise price	$	7.44		$	6.23		$	7.11
Weighted-average grant-date fair value	$	2.84		$	2.60		$	3.07
Black-Scholes Assumptions
Expected volatility	36		%	43		%	42		%
Expected term (in years, weighted)	5.9			5.9			6.1
Risk-free interest rate	0.89% - 1.72%			0.95% - 1.15%			1.16% - 2.61%
