Earnings Per Share

12 Months Ended

Dec. 31, 2022

The weighted average number of shares outstanding used to compute earnings per common share were as follows (in millions):


	2022	2021	2020
Weighted average common shares outstanding for basic computations	263.7	276.4	280.0
Weighted average dilutive effect of equity awards	0.9	1.0	1.2
Weighted average common shares outstanding for diluted computations	264.6	277.4	281.2

We compute basic and diluted earnings per common share by dividing net earnings by the respective weighted average number of common shares outstanding for the periods presented. Our calculation of diluted earnings per common share also includes the dilutive effects for the assumed vesting of outstanding restricted stock units (RSUs) and performance stock units (PSUs) based on the treasury stock method. There were no significant anti-dilutive equity awards for the years ended December 31, 2022, 2021 and 2020. Basic and diluted weighted average common shares outstanding decreased in 2022 compared to 2021 due to share repurchases.
