Earnings Per Share

12 Months Ended

Dec. 31, 2021

The computations of the weighted average shares outstanding for the years ended December 31, are as follows (in millions):


	2021	2020	2019
Weighted-average shares outstanding	425.3	424.1	423.2
Share-based payment awards classified as participating securities	—	—	0.1
Basic weighted-average shares outstanding	425.3	424.1	423.3
Dilutive securities (1)	2.7	—	0.6
Diluted weighted-average shares outstanding	428.0	424.1	423.9

(1)For 2020, 1.1 million potentially dilutive share-based awards were excluded as their effect would be anti-dilutive.

At December 31, 2019 there were 0.5 million potentially dilutive restricted share awards with performance-based vesting targets that were not met and as such, have been excluded from the computation of diluted earnings per share.

For 2021, 2020 and 2019 dividends and equivalents for share-based awards expected to be forfeited did not have a material impact on net income for basic and diluted earnings per share.
