Weighted Average Common Shares [Abstract]

Weighted Average Numbers Of Common Shares Used To Compute Basic And Diluted Net Income Per Share

	For the Year Ended December 31,
	2011(1)		2010		2009
	(In thousands)
Basic common shares outstanding		74,498		79,902		85,838
Common stock equivalents		—		948		580
Diluted common shares outstanding		74,498		80,850		86,418

(1) Due to the fact that we had a loss from continuing operations for the year ended December 31, 2011, potential common stock equivalents are excluded from the diluted common shares outstanding calculation. Per FASB ASC Topic 260—Earnings Per Share, an entity that reports discontinued operations shall use income or loss from continuing operations as the benchmark for calculating diluted common shares outstanding, and as such, we have zero common stock equivalents since these shares would have an anti-dilutive effect on our net income per share for the year ended December 31, 2011.
