Net Income (Loss) Per Share [Abstract]

NET INCOME (LOSS) PER SHARE

NOTE 10: NET INCOME (LOSS) PER SHARE

Basic net income (loss) per share is computed by dividing the net income (loss) attributable to common stockholders for the period by the weighted average number of common shares outstanding during the period. In the years ended December 31, 2011, 2010 and 2009, there were 14,770,995, 18,774,438 and 13,280,168, respectively, of potentially dilutive shares, consisting of options, restricted stock units and employee stock purchase plan awards, excluded from the net income (loss) per share computations because their effect was antidilutive.

Following is a reconciliation of the denominators of the basic and diluted net income (loss) per share computations:

	Year Ended December 31,
	2011		2010			2009
	(In thousands, except per share amounts)
Net income (loss) (numerator)	$	8,779	$	(4,335	)	$	(24,139	)
Shares calculation (denominator):
Weighted average shares outstanding - basic		115,175		101,487			95,833
Effect of Dilutive Securities:
Potential common stock relating to stock options, restricted stock units and ESPP		1,252		—			—
Weighted averages shares outstanding - diluted		116,427		101,487			95,833
Net income (loss) per share - basic	$	0.08	$	(0.04	)	$	(0.25	)
Net income (loss) per share - diluted	$	0.08	$	(0.04	)	$	(0.25	)

The diluted net loss per share is the same as basic net loss per share for the years ended December 31, 2010 and 2009 because potential common shares are only considered when their effect would be dilutive.
