Earnings Per Share [Abstract]

Earnings Per Common Share

. Earnings (Loss) per Common Share

The following table provides the basis for earnings (loss) per share calculations by reconciling basic and diluted weighted average shares outstanding: 

	Year Ended December 31
	2012	2011	2010
	(In thousands)
Weighted average shares outstanding:
Basic weighted average shares outstanding	211,381	190,086	162,398
Effect of common stock equivalents under incentive plans	—	819	812
Diluted weighted average shares outstanding	211,381	190,905	163,210

The effect of options to purchase 5.2 million, 2.6 million and 2.5 million shares of common stock were excluded from the calculation of diluted weighted average shares outstanding for the years ended December 31, 2012, 2011 and 2010, respectively, because the exercise price of these options exceeded the average market price of the Company's common stock for this period. The weighted average share impact of options, restricted stock and restricted stock units that were excluded from the calculation of weighted average shares for the year ended December 31, 2012 due to the Company's net loss were not significant.
