Net Income Per Share [Abstract]

Net Income Per Share

Note 2. Net Income Per Share:

Net income per share is based on the weighted average number of shares outstanding. A reconciliation of the shares used in the computation of basic and diluted net income per share is as follows:

	Three Months Ended September 30,				Nine Months Ended September 30,
(Shares in thousands)	2011		2010		2011		2010
Basic		80,644		79,357		80,381		79,078
Assumed dilution under stock plans		984		909		1,041		919
Diluted		81,628		80,266		81,422		79,997

Stock options and stock settled appreciation rights ("SSAR's") to purchase 78,000 and 378,000 shares were outstanding as of September 30, 2011 and 2010, respectively, but were not included in the computation of diluted net income per share since the impact was anti-dilutive.

We have issued shares of purchased restricted common stock ("PRS") which contain nonforfeitable rights to dividends and thus are considered participating securities which are required to be included in the computation of basic and diluted earnings per share pursuant to the two-class method. We did not present the two-class method since the difference between basic and diluted net income per share for both common shareholders and PRS shareholders was approximately $0.01 per share or less for each period presented and the number of PRS outstanding as of September 30, 2011 and 2010 was immaterial (approximately 0.6% of the total number of common shares outstanding for both periods). Net income allocated to such PRS was $0.5 million during each of the three months ended September 30, 2011 and 2010 and $1.5 million and $1.3 million during the nine months ended September 30, 2011 and 2010, respectively.
