Total stock-based compensation expense recognized was as follows (in thousands):

	Quarters Ended September 30,				Nine Months Ended September 30,
	2012		2011		2012		2011
Total stock-based compensation expense	$	2,354	$	2,957	$	6,419	$	9,086

The fair value of options granted determined using the Black-Scholes model used the following weighted-average assumptions:

	Quarters Ended September 30,				Nine Months Ended September 30,
	2012		2011		2012		2011
Expected dividend yield	0	%	0	%	0	%	0	%
Risk-free interest rate	0.48	%	0.82	%	0.51	%	1.71	%
Expected life (years)	4.1		4.0		4.1		4.0
Volatility	58	%	54	%	58	%	54	%

The total stock-based compensation amounts for 2012 and 2011 disclosed above are recorded in their respective line items within operating expenses in the consolidated statement of operations, including amounts that are reported in Restructuring and other charges. No stock-based compensation was capitalized as part of the cost of an asset as of September 30, 2012 or December 31, 2011. As of September 30, 2012, we had $12.5 million of total unrecognized compensation cost, net of estimated forfeitures, related to stock awards. The unrecognized compensation cost is expected to be recognized over a weighted-average period of approximately 3 years.
