Earnings (Loss) Per Share [Abstract]

Earnings (Loss) Per Share

12. Earnings (Loss) Per Share

Basic earnings (loss) per share is computed by dividing income available to common stockholders by the weighted average number of shares outstanding for the periods presented. The calculation of diluted earnings (loss) per share includes the potential dilutive impact of non-vested restricted shares outstanding during the periods presented, unless their effect is anti-dilutive.

The following is a calculation of the basic and diluted weighted-average shares outstanding for the periods presented:

		September 30,		September 30,
	Year Ended December 31,
	2011		2010
	(In thousands)
Basic weighted average common shares outstanding(1)		92,056		48,395
Dilution effect of stock awards at end of period(2)		185		—
Diluted weighted average common shares outstanding		92,241		48,395
Anti-dilutive stock-based compensation awards		160		120

(1) The basic weighted average shares outstanding calculation is based on the actual days in which the shares were outstanding for the period from June 22, 2010, the closing date of the Company's IPO, to December 31, 2010.

(2) Because the Company reported a net loss for the year ended December 31, 2010, no unvested stock awards were included in computing loss per share because the effect was anti-dilutive.
