Earnings Per Common Share

3. EARNINGS PER COMMON SHARE

The computation of basic and diluted earnings per share is as follows (in thousands, except per share amounts):

	Three Months Ended							Nine Months Ended
	Net Income		Shares		Per Share Amount			Net Income		Shares		Per Share Amount
June 30, 2011:
Basic earnings per share	$	75,285		64,820	$	1.16		$	198,747		64,689	$	3.07
Effect of dilutive securities:
Stock options		—		650	$	(0.01	)		—		666	$	(0.03	)
Diluted earnings per share	$	75,285		65,470	$	1.15		$	198,747		65,355	$	3.04
June 30, 2010:
Basic earnings per share	$	58,994		64,427	$	0.92		$	192,733		64,375	$	2.99
Effect of dilutive securities:
Stock options		—		610	$	(0.01	)		—		679	$	(0.03	)
Diluted earnings per share	$	58,994		65,037	$	0.91		$	192,733		65,054	$	2.96

The calculation of diluted earnings per share for the three and nine month period ended June 30, 2011 and 2010 excludes consideration of shares of common stock related to 684,000 and 508,000 outstanding stock options, respectively, because such options were anti-dilutive. These options could potentially dilute basic earnings per share in the future.
