22. Net (Loss) Income per Share

Basic net (loss) income per share is computed by dividing net (loss) income by the weighted-average number of common shares outstanding for the period. Diluted net (loss) income per share is computed giving effect to all potential dilutive common stock, including employee stock options, restricted stock units, stock purchase plan, and contingently issuable shares.

The calculation of basic and diluted net (loss) income per share for the years ended December 31, 2012, December 31, 2011, and December 31, 2010 was as follows (in thousands, except per share amounts):

	2012			2011			2010
Basic net (loss) income per share
Numerator:
Net (loss) income	$	(96,338	)	$	(39,493	)	$	664,201
Denominator:

Diluted net (loss) income per share

Weighted-average shares used in computing diluted net (loss) income per share	86,860			86,067			86,491

	2012			2011			2010
Per share information - basic:
Net (loss) income per share	$	(1.11	)	$	(0.46	)	$	7.82
Per share information - diluted:
Net (loss) income per share	$	(1.11	)	$	(0.46	)	$	7.68

The following number of outstanding employee stock options, restricted stock units, and stock purchase plan shares were excluded from the computation of diluted net (loss) income per share for the years ended December 31, 2012, December 31, 2011, and December 31, 2010 as they would have had an antidilutive effect (in thousands):

	2012	2011	2010
Antidilutive shares	1,497	630	118
