| 3.15 | Share-based payments |
Employees of the Group receive remuneration in the form of share-based payments, whereby employees render services as consideration for equity instruments (equity-settled transactions).
The cost of equity-settled transactions is recognized, together with a corresponding increase in other reserves in equity, over the period in which the performance and/or service conditions are fulfilled. The cumulative expense recognized for equity-settled transactions at each reporting date until the vesting date reflects the extent to which the vesting period has expired and the Group’s best estimate of the number of equity instruments that will ultimately vest. The statement of comprehensive income expense or credit for a period represents the movement in cumulative expense recognized as of the beginning and end of that period and is recognized in compensation to employees and other personnel expenses.
No expense is recognized for awards that do not ultimately vest, except for equity-settled transactions for which vesting is conditional upon a market or non-vesting condition. These are treated as vested irrespective of whether or not the market or non-vesting condition is satisfied, provided that all other performance and/or service conditions are satisfied.
When the terms of an equity-settled award are modified, the minimum expense recognized is the expense that would have been incurred had the terms not been modified, if the original terms of the award are met. An additional expense is recognized for any modification that increases the total fair value of the share-based payment transaction, or is otherwise beneficial to the employee as measured at the date of modification.
When an equity-settled award is cancelled, it is treated as if it vested on the date of cancellation, and any expense not yet recognized for the award is recognized immediately. This includes any award where non-vesting conditions within the control of either the entity or the employee are not met. However, if a new award is substituted for the cancelled award, and designated as a replacement award on the date that it is granted, the cancelled and new awards are treated as if they were a modification of the original award, as described in previous paragraph.
The dilutive effect of outstanding options is reflected as additional share dilution in the computation of diluted earnings per share.
The option awards that are outstanding as of December 31, 2017, 2016 and 2015 can only be settled in shares, that is why they are accounted for as equity-settled transactions.
