The following table sets forth a reconciliation of the information used in computing basic and diluted earnings per share:

	2012			2011
Earnings from continuing operations	$	196,827		$	174,791
Earnings (loss) from discontinued operations, net		(764	)		20,114
Net earnings	$	196,063		$	194,905

Basic earnings (loss) per common share:
Earnings from continuing operations	$	1.07		$	0.94
Earnings (loss) from discontinued operations, net	$	-		$	0.11
Net earnings	$	1.07		$	1.04

Weighted average shares outstanding		183,737			186,659

Diluted earnings (loss) per common share:
Earnings from continuing operations	$	1.05		$	0.92
Earnings (loss) from discontinued operations, net	$	-		$	0.11
Net earnings	$	1.05		$	1.03

Weighted average shares outstanding		186,706			190,090

The following table is a reconciliation of the share amounts used in computing earnings per share:

	Three Months Ended March 31,
	2012	2011
Weighted average shares outstanding - Basic	183,737	186,659
Dilutive effect of assumed exercise of employee stock options, SARs and performance shares	2,969	3,431
Weighted average shares outstanding - Diluted	186,706	190,090

Diluted per share amounts are computed using the weighted-average number of common shares, and if dilutive, potential common shares outstanding the period. Potential common shares consist of the incremental common shares issuable upon the exercise of stock options and SARs, and vesting of performance shares and restricted shares, as determined using the treasury stock method. For the three months ended March 31, 2012 and 2011, the weighted average number of anti-dilutive potential common shares excluded from the calculation above totaled 2,437 and 1,524, respectively.
