(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. As of December 31, 2020, there were 261 thousands (2019: 645 thousands; 2018: 851 thousands) share options/restricted units outstanding that could potentially have a dilutive impact in the future but were antidilutive for the periods presented.
