Further details are set out in note 13. Useful lives of property, plant and equipment In applying the accounting policy on property, plant and equipment (Note 13) with respect to depreciation, the directors of the Company estimate the useful lives of various categories of property, plant and equipment according to their experiences over the usage of property, plant and equipment and also by reference to the relevant industrial norm. The useful lives of property, plant and equipment are reviewed annually. If the expectations differ from the previous estimates, the changes will be accounted for prospectively as changes in accounting estimates. Allowance for inventories In determining the amount of allowance required for obsolete and slow-moving inventories, the directors of the Company would evaluate ageing analysis of inventories and compare the carrying value of inventories to their respective net realisable values based on latest market prices and current economic conditions. A considerable amount of judgement is required in determining such allowance. If conditions which have an impact on the net realisable value of inventories deteriorate/improve, additional allowances/reversal of allowances already made may be required. The carrying amount of inventories as at 31st December, 2019 was HK$93,861,000 (net of allowance for inventories of HK$1,956,000) (2018: HK$258,661,000 (net of allowance for inventories of HK$1,989,000)).
