Earnings Per Share

9 Months Ended

Sep. 30, 2023

The calculation of earnings per share is based on the weighted-average number of the Company’s shares outstanding for the applicable period. The calculation of diluted earnings per share reflects the effect of all potentially dilutive shares that were outstanding during the respective periods, unless the effect of doing so is antidilutive. The Company uses the treasury stock method to calculate the dilutive effect of outstanding share-based compensation awards. The number of weighted-average shares outstanding used in the computations of basic and diluted earnings per share are as follows.


	For the Three Month Period Ended September 30,		For the Nine Month Period Ended September 30,
	2023	2022	2023	2022


Weighted-average shares outstanding - Basic	404.5	404.0	404.8	405.4
Dilutive effect of outstanding share-based compensation awards	4.1	4.5	4.1	4.9
Weighted-average shares outstanding - Diluted	408.6	408.5	408.9	410.3

For the three month periods ended September 30, 2023 and 2022, 0.8 million and 2.3 million, respectively, of anti-dilutive shares were not included in the computation of diluted earnings per share. For the nine month periods ended September 30, 2023 and September 30, 2022, 1.4 million and 2.1 million of anti-dilutive shares were not included in the computation of diluted earnings per share, respectively.
