Earnings per share [abstract] |
Earnings per share | 9. Earnings per share Basic earnings per share is calculated by dividing the profit for the year attributable to equity holders of the Company by the weighted average number of ordinary shares outstanding during the year. Diluted earnings per share is calculated by dividing the profit attributable to equity holders of the Company by the weighted average number of ordinary shares outstanding during the year plus the weighted average number of ordinary shares that would be issued on conversion of all the dilutive potential ordinary shares into ordinary shares. Basic earnings per share The calculation of basic earnings per share is based on:

Diluted earnings per share The weighted average number of ordinary shares adjusted for the effect of unissued ordinary shares under the Share Option Scheme is determined as follows:
|  | 31.12.2022 |  |  | 31.12.2023 |  |  | 31.12.2024 |
Weighted average number of shares issued, used in the calculation of basic earnings per share |  |  | 40,858,290 |  |  |  | 40,858,290 |  |  |  | 39,325,763 |

* The weighted average number of ordinary shares takes into account the weighted average effect of changes in treasury shares transactions during the year. In 2022 and 2023, 270,000 outstanding share options granted to employees under the Company’s Equity Incentive Plan have not been included in the calculation of diluted earnings per share because they are anti-dilutive. The Equity Incentive Plan expired in 2024.
