Earnings Per Share [Abstract]

Earnings Per Share

Earnings per share

Basic earnings per share has been calculated using Net income for the period divided by the weighted-average number of shares outstanding during the period. The number of shares used in the earnings per share calculations are reconciled as follows:

	For the three months ended September 30		For the nine months ended September 30
(in millions)	2022	2021	2022	2021
Weighted-average basic shares outstanding	930.0	666.9	929.9	666.7
Dilutive effect of stock options	2.9	2.9	2.9	3.1
Weighted-average diluted shares outstanding	932.9	669.8	932.8	669.8

For the three and nine months ended September 30, 2022, there were nil and 0.3 million options, respectively, excluded from the computation of diluted earnings per share because their effects were not dilutive (three and nine months ended September 30, 2021 - 0.2 million and 0.1 million, respectively).
