B4 | Earnings per share
Basic earnings per share are calculated based on earnings attributable to ordinary shareholders, after related tax and non-controlling interests, divided by the weighted average number of ordinary shares outstanding during the year, excluding those held in employee share trusts, which are treated as cancelled. For diluted earnings per share, the weighted average number of shares in issue is adjusted to assume conversion of all dilutive potential ordinary shares. No adjustment is made if the impact is anti-dilutive overall. ​

​ For 2024, the weighted average number of shares for calculating basic earnings per share, that excludes those held in employee share trusts, is 2,715 million (2023: 2,741 million; 2022: 2,736 million). After including a dilutive effect of the Group's share options and awards of 5 million (2023: 6 million), the weighted average number of shares for calculating diluted earnings per share is 2,720 million (2023: 2,747 million). As the Group made a loss for the year in 2022, the potential ordinary shares from the Group's share options and awards (see note B2.2) would be anti-dilutive and therefore not included in the diluted earnings per share calculation as it is not permissible for the diluted earnings per share to be greater than the basic earnings per share.
