Basic earnings per share (EPS) is calculated by dividing On’s net income for the period by the weighted average number of ordinary shares outstanding during the year.

Diluted EPS is calculated by dividing On’s net income for the period by the weighted average number of ordinary shares outstanding during the year plus the weighted average number of ordinary shares that would be issued at conversion of all the dilutive potential ordinary shares into ordinary shares. Dilutive effects arise from equity-settled awards from the Company's share-based plans. These shares are included even if the service conditions are not met, or respective performance conditions were fulfilled at the end of the reporting period.
