| 11. | EMPLOYEE BENEFITS |
| 11.1 | Short-term employee benefits |
Short-term employee benefits are expensed as the related service is provided. A liability is recognised for the amount expected to be paid if the Group has a present legal or constructive obligation to pay this amount as a result of past service provided by the employee and the obligation can be estimated reliably.
| 11.2 | Pension and provident funds |
The Group operates a defined contribution retirement plan and contributes to a number of industry-based defined contribution retirement plans. The retirement plans are funded by payments from employees and Group companies.
Contributions to defined contribution funds are recognised as an employee benefit expense in profit or loss in the periods during which related services are rendered by employees.
| 11.3 | Share-based payments |
The Group operates a number of equity-settled compensation plans. The fair value of the equity-settled instruments is measured by reference to the fair value of the equity instrument granted which in turn is determined using the Black-Scholes and Monte Carlo simulation models on the date of grant.
Fair value is based on market prices of the equity-settled instruments granted, if available, taking into account the terms and conditions upon which those equity-settled instruments were granted. Fair value of equity-settled instruments granted is estimated using appropriate valuation models and appropriate assumptions at grant date. Non-market vesting conditions (service period prior to vesting) are not taken into account when estimating the fair value of the equity-settled instruments at grant date. Market conditions are taken into account in determining the fair value at grant date.
The fair value of the equity-settled instruments is recognised as an employee benefit expense over the vesting period based on the Group’s estimate of the number of instruments that will eventually vest, with a corresponding increase in equity. Vesting assumptions for non-market conditions are reviewed at each reporting date to ensure they reflect current expectations.
Where the terms of an equity-settled award are modified, the originally determined expense is recognised as if the terms had not been modified. In addition, an expense is recognised for any modification, which increases the total fair value of the share-based payment arrangement, or is otherwise beneficial to the participant as measured at the date of the modification.
| 11.4 | Long-term incentive plan |
The Group operates a long-term incentive plan.
The Group’s net obligation in respect of the long-term incentive plan is the amount of future benefit that employees have earned in return for their services in the current and prior periods. That benefit is estimated using appropriate assumptions and is discounted to determine its present value at each reporting date. Re-measurements are recognised in profit or loss in the period in which they arise.
| 11.5 | Termination benefits |
Termination benefits are payable when employment is terminated by the Group before the normal retirement date, or whenever an employee accepts voluntary redundancy in exchange for these benefits. Termination benefits are expensed at the earlier of the date the Group can no longer withdraw the offer of those benefits or the date the Group recognises costs for a restructuring. Benefits falling due more than 12 months after the reporting date are discounted to present value.
