(c) for goods or services measured by reference to the fair value of the equity instruments granted, the IFRS specifies that vesting conditions, other than market conditions, are not taken into account when estimating the fair value of the shares or options at the relevant measurement date (as specified above). Instead, vesting conditions are taken into account by adjusting the number of equity instruments included in the measurement of the transaction amount so that, ultimately, the amount recognised for goods or services received as consideration for the equity instruments granted is based on the number of equity instruments that eventually vest. Hence, on a cumulative basis, no amount is recognised for goods or services received if the equity instruments granted do not vest because of failure to satisfy a vesting condition (other than a market condition).
