Net Income (Loss) Per Share

12.   Net Income (Loss) Per Share

Basic net income (loss) per share amounts have been computed based on the weighted-average number of common shares outstanding.  Diluted net income (loss) per share amounts have been computed based on the weighted-average number of common shares outstanding plus the dilutive effect of potential common shares.  The computation of potential common shares has been performed using the treasury stock method.  The changes in income or loss that would result if the warrants were reported as an equity instrument are reflected as an adjustment to the numerator when warrants would be dilutive.  The warrants are antidilutive for all periods presented.  When net loss is reported, diluted and basic net loss per share amounts are the same as the impact of potential common shares is antidilutive.

The calculation of net income (loss) and the number of shares used to compute basic and diluted earnings per share for the years ended December 31, 2011, 2010 and 2009 are as follows:

In thousands	2011			2010		2009
Net income (loss)	$	(123,603	)	$	85,248	$	(80,008	)
Weighted average shares outstanding - basic		132,375			113,020		93,330
Dilutive stock options		---			572		---
Restricted stock and restricted stock units		---			1,142		---
Weighted average shares outstanding ­- diluted		132,375			114,734		93,330

For the years ended December 31, 2011, 2010 and 2009, the following potentially dilutive securities were not included in the computation of net income (loss) per share because the effect would be anti-dilutive:
