Weighted average common shares outstanding for computing EPS

The following is a reconciliation of the weighted-average common shares outstanding for purposes of computing basic and diluted net income per share (in thousands):

	Year Ended December 31,
	2011		2012		2013
Basic weighted-average common shares outstanding		62,066		60,600		58,606
Effect of dilutive securities:
Stock awards and options		2,480		2,425		2,842
Diluted weighted-average common shares outstanding		64,546		63,025		61,448

For the years ended December 31, 2011, 2012 and 2013, other stock options totaling none, 0.1 million and 1.2 million, respectively, were excluded from the calculation of diluted earnings per share because they were anti-dilutive.
