17. Earnings per Share

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

	Three Months Ended June 30,				Six Months Ended June 30,
	2012		2011		2012		2011
Earnings from continuing operations	$	212,902	$	239,198	$	409,729	$	413,989
Earnings from discontinued operations, net	1,199		10,571		435		30,685
Net earnings	$	214,101	$	249,769	$	410,164	$	444,674
Basic earnings per common share:
Earnings from continuing operations	$	1.16	$	1.28	$	2.23	$	2.22
Earnings from discontinued operations, net	$	0.01	$	0.06	$	—	$	0.16
Net earnings	$	1.17	$	1.34	$	2.23	$	2.38
Weighted average shares outstanding	183,494,000		186,443,000		183,625,000		186,522,000
Diluted earnings per common share:
Earnings from continuing operations	$	1.15	$	1.26	$	2.20	$	2.18
Earnings from discontinued operations, net	$	0.01	$	0.06	$	—	$	0.16
Net earnings	$	1.15	$	1.32	$	2.20	$	2.34
Weighted average shares outstanding	185,780,000		189,705,000		186,171,000		189,905,000

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

	Three Months Ended June 30,		Six Months Ended June 30,
	2012	2011	2012	2011
Weighted average shares outstanding - Basic	183,494,000	186,443,000	183,625,000	186,522,000
Dilutive effect of assumed exercise of employee stock options, SARs and performance shares	2,286,000	3,262,000	2,546,000	3,383,000
Weighted average shares outstanding - Diluted	185,780,000	189,705,000	186,171,000	189,905,000

Diluted per share amounts are computed using the weighted-average number of common shares and, if dilutive, potential common shares outstanding during 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 June 30, 2012 and 2011, the weighted average number of anti-dilutive potential common shares excluded from the calculation above totaled 3,135,000 and 1,513,000, respectively.  For the six months ended June 30, 2012 and 2011, the weighted average number of anti-dilutive potential common shares excluded from the calculation above totaled 2,784,000 and 1,184,000, respectively.
