20. STAFF RETIREMENT SCHEMES
The Company operates separate staff retirement schemes for their monthly and daily-rated employees. Contributions under these staff retirement schemes applicable to each year are charged against income for the year. The costs of these schemes are determined by actuarial valuations periodically. The assets of these schemes are held separately from those of the Company.
Actuarial valuations of the schemes are carried out normally at three-year intervals. The latest full actuarial valuation of the scheme carried out as at 31st December, 1991 indicated that, in the opinion of the actuary, there was no shortfall of the net realisable value of the assets of the scheme from the actuarially determined value of vested benefits of the members at that date.
