Risk exposure
Through its defined benefit plans, the Group is exposed to a number of risks, the most significant of which are detailed
below:
i)
Asset volatility
The plan liabilities are calculated using a discount rate set with reference to bond yields; if plan assets underperform
this yield, this will create a deficit. Most of the plan asset investments is in fixed income securities with high grades
and in Government securities. These are subject to interest rate risk. The Group has a Risk Management strategy
where the aggregate amount of risk exposure on a portfolio level is maintained at a fixed range. Any deviations
from the range are corrected by rebalancing the portfolio. The Group intends to maintain the above investment
mix in the continuing years.
ii)
Changes in bond yields
A decrease in bond yields will increase plan liabilities, although this will be partially offset by an increase in the value
of bond holdings.
The Group actively monitors how the duration and the expected yield of the investments are matching the expected
cash outflows arising from the employee benefit obligations. The Group has not changed the processes used
to manage its risks from previous periods. Investments are well diversified, such that the failure of any single
investment will not have a material impact on the overall level of assets.
A large portion of assets in 2017 consists of insurance funds, although the Group also invests in corporate bonds
and special deposit scheme. The plan asset mix is in compliance with the requirements of the respective local
regulations.
