(b) Diluted Diluted earnings per share is calculated by adjusting the weighted average number of shares outstanding to assume conversion of all dilutive potential shares. The Group has two categories of dilutive potential shares: equity-settled share options and restricted units. For these instruments, a calculation is done to determine the number of shares that could have been acquired at fair value, based on the monetary value of the subscription rights attached to outstanding share options. The number of shares calculated as above is compared with the number of shares that would have been issued assuming the exercise of the equity-settled share options. During 2022, the share options outstanding average were 361 thousands (2021: 466 thousands; 2020: 261 thousands) share options outstanding.
