Earnings Per Common Share [Abstract]

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
	Net Income		Shares		Per Share Amount
December 31, 2011:
Basic earnings per share	$	65,468		65,024	$	1.01
Effect of dilutive securities - Stock options		—		517		(0.01	)
Diluted earnings per share	$	65,468		65,541	$	1.00
December 31, 2010:
Basic earnings per share	$	52,850		64,528	$	0.82
Effect of dilutive securities - Stock options		—		656		(0.01	)
Diluted earnings per share	$	52,850		65,184	$	0.81

The calculation of diluted earnings per share for the three-month periods ended December 31, 2011 and 2010 excludes consideration of shares of common stock related to 977,000 and 740,000 outstanding stock options, respectively, because such options were anti-dilutive. These options could potentially dilute basic earnings per share in the future.
