Earnings Per Share

18. 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,
	2022		2021		2022		2021
Net earnings	$	289,618	$	264,508	$	515,771	$	497,277
Basic earnings per common share:
Net earnings	$	2.01	$	1.84	$	3.58	$	3.46
Weighted average shares outstanding	143,832,000		143,941,000		143,959,000		143,854,000
Diluted earnings per common share:
Net earnings	$	2.00	$	1.82	$	3.56	$	3.43
Weighted average shares outstanding	144,669,000		145,118,000		144,998,000		145,040,000

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,
	2022	2021	2022	2021
Weighted average shares outstanding - Basic	143,832,000	143,941,000	143,959,000	143,854,000
Dilutive effect of assumed exercise of SARs and vesting of performance shares and RSUs	837,000	1,177,000	1,039,000	1,186,000
Weighted average shares outstanding - Diluted	144,669,000	145,118,000	144,998,000	145,040,000

Diluted earnings per share amounts are computed using the weighted average number of common shares outstanding and, if dilutive, potential common shares outstanding during the period. Potential common shares consist of the incremental common shares issuable upon the exercise of SARs and vesting of performance shares and RSUs, as determined using the treasury stock method.

The weighted average number of anti-dilutive potential common shares excluded from the calculation above were approximately 6,000 and 0 for the three months ended June 30, 2022 and 2021, respectively, and 32,000 and 34,000 for the six months ended June 30, 2022 and 2021, respectively.
