111 ANNUAL REPORT 2023 2. MATERIAL ACCOUNTING POLICY INFORMATION (CONTINUED) 2.10 Financial assets (continued) (iii) Derecognition of financial assets The Group derecognises a financial asset only when the contractual rights to the cash flows from the asset expire, or when it transfers the financial asset and substantially all the risks and rewards of ownership of the asset to another entity. If the Group neither transfers nor retains substantially all the risks and rewards of ownership and continues to control the transferred asset, the Group recognises its retained interest in the asset and an associated liability for amounts it may have to pay. If the Group retains substantially all the risks and rewards of ownership of a transferred financial asset, the Group continues to recognise the financial asset and also recognises a collateralised borrowing for the proceeds received. On derecognition of a financial asset measured at amortised cost, the difference between the asset’s carrying amount and the sum of the consideration received and receivable is recognised in profit or loss. On derecognition of an investment in equity instrument which the Group has elected on initial recognition to measure at FVTOCI, the cumulative gain or loss previously accumulated in the investments revaluation reserve is not reclassified to profit or loss, but is transferred to retained earnings. 2.11 Impairment of financial assets and financial guarantee contracts The Group performs impairment assessment under expected credit loss (“ECL”) model on financial assets and financial guarantee contracts which are subject to impairment assessment under HKFRS 9 (including trade debtors, other debtors and other financial assets). The amount of ECL is updated at each reporting date to reflect changes in credit risk since initial recognition. Lifetime ECL represents the ECL that will result from all possible default events over the expected life of the relevant instrument. In contrast, 12-month ECL (“12m ECL”) represents the portion of lifetime ECL that is expected to result from default events that are possible within 12 months after the reporting date. Assessment is done based on the Group’s historical credit loss experience, adjusted for factors that are specific to the trade debtors, general economic conditions and an assessment of both the current conditions at the reporting date as well as the forecast of future conditions. The Group always recognises lifetime ECL for trade debtors. The ECL on these assets are assessed individually for trade debtors with significant balances and collectively for others based on internal credit rating with appropriate groupings. For all other instruments, the Group measures the loss allowance equal to 12m ECL, unless when there has been a significant increase in credit risk since initial recognition, the Group recognises lifetime ECL. The assessment of whether lifetime ECL should be recognised is based on significant increases in the likelihood or risk of a default occurring since initial recognition.
