Earnings or Loss per Share

3 Months Ended

Mar. 31, 2021

Basic earnings or loss per share (EPS) is computed by dividing net earnings or loss by the weighted average number of shares outstanding for the period. Diluted EPS presents the dilutive effect, if any, on a per share basis of potential shares (e.g., options, SARs, RSUs, PSARs and PSUs) as if they had been exercised, vested or converted at the beginning of the periods presented.

The details of our basic and diluted weighted average ordinary shares outstanding are set forth below:

		2021	2020

Weighted average ordinary shares outstanding (basic EPS computation)		575,114,550	630,472,769
Incremental shares attributable to the assumed exercise of outstanding options and SARs and the release of RSUs and PSUs upon vesting (treasury stock method)		9,507,525	1,305,793
Weighted average ordinary shares outstanding (diluted EPS computation)		584,622,075	631,778,562

During the three months ended March 31, 2021 and 2020, a total of 51.6 million and 59.7 million options, SARs and RSUs, respectively, and 16.9 million and 22.2 million PSARs and PSUs, respectively, were excluded from the calculation of diluted earnings per share because their effect would have been anti-dilutive or, in the case of the PSARs and PSUs, because such awards had not yet met the applicable performance criteria.
