Earnings Per Share [Abstract] |
Computation of Earnings Per Share | Earnings per share are computed as follows:
|  | 2022 |  |  | 2021 |
Basic earnings per Common Share: |  |  |  |  |  |  |  |
Net income attributable to Magna International Inc. |  | $ | 592 |  |  | $ | 1,514 |
Weighted average number of Common Shares outstanding during the year |  |  | 290.4 |  |  |  | 300.6 |
Basic earnings per Common Share |  | $ | 2.04 |  |  | $ | 5.04 |
Diluted earnings per Common Share [a]: |  |  |  |  |  |  |  |
Net income attributable to Magna International Inc. |  | $ | 592 |  |  | $ | 1,514 |
Weighted average number of Common Shares outstanding during the year |  |  | 290.4 |  |  |  | 300.6 |
Stock options and restricted stock |  |  | 0.8 |  |  |  | 2.2 |
|  |  | 291.2 |  |  |  | 302.8 |
Diluted earnings per Common Share |  | $ | 2.03 |  |  | $ | 5.00 |
[a] | Diluted earnings per Common Share exclude 1.3 million [2021 – 0.4 million] Common Shares issuable under the Company’s Incentive Stock Option Plan because these options were not “in-the-money”. The dilutive effect of participating securities using the two-class method was excluded from the calculation of earnings per share because the effect would be immaterial.
