Equity-settled share-based payments
The Group issues equity settled share-based payments to certain directors, senior management and employees. Options under the awards were measured at fair value at the date of grant. An expense is recognized to spread the fair value of each award over the vesting period on a straight-line basis, after allowing for an estimate of the awards that will eventually vest. The estimate of the level of vesting is reviewed at least annually, with any impact on the cumulative charge being recognized immediately.
