KEY SOURCES OF ESTIMATION UNCERTAINTY (Continued) Useful lives of property, plant and equipment In applying the accounting policy on property, plant and equipment (note 14) 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, 2020 was HK$143,471,000 (net of allowance for inventories of HK$2,071,000) (2019: HK$93,861,000 (net of allowance for inventories of HK$1,956,000)). Provision of ECL for trade receivables Trade receivables that are credit-impaired are assessed for ECL individually. In addition, for trade receivables that are not credit-impaired, collective assessment is performed by grouping debtors based on the aging grouping of trade receivables. The grouping is based on past due status as groupings of various debtors that have similar loss patterns taking into consideration past default experience and current past due status of the debtors. At every reporting date, the historical observed default rates are reassessed and changes in the forward-looking information are considered. The provision of ECL is sensitive to changes in estimates. The information about the ECL and the Group’s trade receivables are disclosed in notes 32 and 17 respectively.
