LTIP The Group and the Company operate an equity-settled share-based compensation plan under which the entity receives services from employees as consideration for equity instruments of the Group. The fair value of the employee services received in exchange for the grant of the Company’s shares is recognised as an expense inthe statement of profit or loss over the vesting period of the grant, with a corresponding increase in share-based payment reserve in equity. The total amount to be expensed over the vesting period is determined by reference to the fair value of the shares granted. Non-market vesting conditions are included in the assumptions to arrive at the number of shares that are expected to vest. At the end of the reporting period, the Company revises its estimates of the number of shares that are expected to be vested. The impact of the revision of original estimates, if any, is recognised in the statement of profit or loss, with a corresponding adjustment to share-based payment reserve in equity. The fair value of shares granted to employees of subsidiaries is allocated to the subsidiaries. The Company implemented a LTIP on 30 April 2015 for a period of 10 years. The LTIP is governed by the by-laws, which was approved by the shareholders at an Extraordinary General Meeting on 18 December 2014.
