Earnings per share

12 Months Ended

Dec. 31, 2021

Basic earnings per share is calculated by dividing profit after taxes by the weighted average number of Shares in issue and outstanding during the period. Diluted earnings per share is calculated in a similar manner, but includes the effect of dilutive securities, principally share options, restricted stock units and performance share units. Share‑based payment awards that are contingently issuable upon the achievement of specified market and/or performance conditions are included in the diluted earnings per share calculation based on the number of Shares that would be issuable if the end of the period was the end of the contingency period.

The following table summarises basic and diluted earnings per share calculations for the years presented:
