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


	Years Ended December 31,
	2022	2021	2020
Weighted average shares outstanding - basic	142,681,000	143,923,000	144,050,000
Dilutive effect of assumed exercise of SARs and vesting of performance shares and RSUs	914,000	1,350,000	1,343,000
Weighted average shares outstanding - diluted	143,595,000	145,273,000	145,393,000

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. For the years ended December 31, 2022, 2021 and 2020, the weighted average number of anti-dilutive potential common shares excluded from the calculation above totaled 21,173, 1,072 and 30,378, respectively.
