3.24 Share-based payments arrangements
Senior executives of the Company receive remuneration in the form of share-based payment transactions, whereby employees render services as consideration for equity instruments. The equity instruments are granted and then held by a trust controlled by the Company until vesting. They are accounted for as equity settled transactions. The award of equity instruments is a fixed monetary value on the grant date.
Equity-settled share-based payments to employees are measured at the fair value of the equity instruments at the grant date. The fair value determined at the grant date of the equity-settled share-based payments is expensed and recognized based on the graded vesting method over the vesting period, based on the Company’s estimate of equity instruments that will eventually vest. At the end of each reporting period, the Company revises its estimate of the number of equity instruments expected to vest. The impact of the revision of the original estimates, if any, is recognized in consolidated income statements such that the cumulative expense reflects the revised estimate.
