As at 31 December 2016, certain of the Group's listed available-for-sale equity securities were individually determined to be impaired on the basis of a material decline in their fair value below cost and adverse changes in the market in which these investees operated which indicated that the cost of the Group's investment in them may not be recovered. Impairment losses of HK$46,281,000 on these investments were recognised in profit or loss in accordance with the policy set out in note 1(k)(i). All the Group's listed available-for-sale equity securities have been disposed of during the year ended 31 December 2017.
NET EMPLOYEE RETIREMENT BENEFITS LIABILITIES
18
(a)
Defined benefit retirement plan
The Group makes contributions to a defined benefit retirement plan registered under the Occupational Retirement Schemes Ordinance (Chapter 426 of the Laws of Hong Kong), which covers 11.2% (2016: 11.7%) of the Group's employees. The plan is administered by independent trustees with their assets held separately from those of the Group.
The plan is funded by contributions from the Group in accordance with an independent actuary's recommendation based on annual actuarial valuations. The latest independent actuarial valuation of the plan was at 31 December 2017 and was prepared by qualified staff of Willis Towers Watson, who are members of recognised actuarial bodies, using the projected unit credit method. The actuarial valuation indicates that the Group's obligations under the defined benefit retirement plan are fully (2016: 100%) covered by the plan assets held by the trustees.
