Earnings Per Share [Abstract]

NET INCOME PER SHARE

NET INCOME PER SHARE

Certain of the Company’s restricted unvested share units contain rights to receive nonforfeitable dividends, and thus, are participating securities requiring the two-class method of computing earnings per share. The participating securities had an insignificant impact on the calculation of earnings per share (impacts the rounding by less than $0.01 per share) on 2011 and 2010 years presented; therefore, the Company does not present the full calculation below.

Basic and diluted net income per share was as follows (in thousands, except per share amounts):

	Years Ended December 31,
	2012		2011		2010
	(In thousands, except per share amounts)
Basic net income per share:
Net income	$	41,204	$	27,989	$	65,669
Weighted average common shares outstanding	28,232		28,952		29,548
Basic net income per common share	$	1.46	$	0.97	$	2.21
Diluted net income per share:
Net income	$	41,204	$	27,989	$	65,669
Weighted average common shares outstanding — Basic	28,232		28,952		29,548
Effect of dilutive securities:
Stock options and restricted stock	284		543		601
Weighted average common shares for diluted earnings per share	28,516		29,495		30,149
Diluted net income per common share	$	1.44	$	0.95	$	2.17

Common stock of approximately 1.0 million, 0.3 million and 0.7 million shares at December 31, 2012, 2011 and 2010, respectively, that are issuable through exercise or conversion of dilutive securities were not included in the computation of diluted net income per share because their effect would have been antidilutive.

Performance Shares and Restricted Units that entitle the holders to approximately 0.1 million shares of common stock are included in the basic and diluted weighted average shares outstanding calculation from their date of issuance because no further consideration is due related to the issuance of the underlying common shares.
