11. EARNINGS PER SHARE

Diluted earnings per share were computed based on the weighted average number of shares outstanding plus all potentially dilutive common shares. A reconciliation of basic to diluted shares used in the earnings per share calculation is as follows:

	(In thousands, except stock options outstanding)
	Three Months Ended		Six Months Ended
	June 30,		June 30,
	2011	2010	2011	2010
Basic weighted average shares outstanding	46,311	45,743	46,250	45,691
Dilutive effect of stock options and deferred stock compensation	704	568	741	542
Diluted weighted average shares outstanding	47,015	46,311	46,991	46,233

As of June 30, 2011 and 2010 there were 660,000 and 672,000 stock options outstanding, respectively, that could potentially dilute earnings per share in the future, which were excluded from the computation of diluted earnings per share as they would be considered anti-dilutive.
