Net Income (Loss) Per Share

Basic net income (loss) per share is based on the weighted average number of common shares outstanding, while diluted net income (loss) per share is based on the weighted average number of common shares outstanding and common stock equivalents that would arise from the exercise of stock options.

The calculation of the basic and diluted net income (loss) per share was as follows:

	Year Ended December 31,
	2011		2010			2009
(In thousands, except share and per-share amounts)
Net income (loss)	$	302,150	$	(1,805,867	)	$	(147,879	)
Average common shares outstanding	132,372		114,697			81,937
Increase in shares due to potential exercise of common stock equivalents—diluted basis	1,491		—			—
Adjusted shares outstanding—diluted	133,863		114,697			81,937
Net income (loss) per share—basic	$	2.28	$	(15.74	)	$	(1.80	)
Net income (loss) per share—diluted	$	2.26	$	(15.74	)	$	(1.80	)

For the year ended December 31, 2011, 2,490,462 shares of our common stock equivalents issued under our stock-based compensation plans were not included in the calculation of diluted net income per share as of such date because they were anti-dilutive. As a result of our net loss in 2010 and 2009, 4,366,342 and 4,635,530 shares, respectively, of our common stock equivalents issued under our stock-based compensation plans were not included in the calculation of diluted net loss per share because they were anti-dilutive.
