Earnings Per Share

Note 13. Earnings Per Share

Basic net income (loss) per share (EPS) is computed by dividing net income (loss) by the weighted average number of common shares outstanding during the period. Diluted EPS is computed by dividing net income (loss) by the weighted average number of common and dilutive potential common shares outstanding during the period. Basic and diluted EPS were calculated as follows (in thousands):

	Quarters Ended March 31,
	2012			2011
Net income (loss) available to common shareholders	$	(17,015	)	$	(12,305	)
Weighted average common shares outstanding used to compute basic EPS		34,488			34,066
Dilutive effect of stock based awards		0			0
Weighted average common shares outstanding used to compute diluted EPS		34,488			34,066
Basic EPS	$	(0.49	)	$	(0.36	)
Diluted EPS	$	(0.49	)	$	(0.36	)

During the quarters ended March 31, 2012 and 2011, 5.9 million and 4.0 million shares of common stock, respectively, of potentially issuable from stock options were excluded from the calculation of diluted EPS because of their antidilutive effect.
