Annual Report 2020

China Merchants China Direct Investments Limited Annual Report 2020 101 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) For the year ended 31 December 2020 3. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) Financial instruments (continued) Financial assets (continued) Impairment of financial assets (continued) Measurement and recognition of ECL The measurement of ECL is a function of the probability of default, loss given default (i.e. the magnitude of the loss if there is a default) and the exposure at default. The assessment of the probability of default and loss given default is based on historical data and forward-looking information. Estimation of ECL reflects an unbiased and probability weighted amount that is determined with the respective risks of default occurring as the weights. ECL is estimated as the difference between all contractual cash flows that are due to the Group in accordance with the contract and all the cash flows that the Group expects to receive, discounted at the effective interest rate determined at initial recognition. Interest income is calculated based on the gross carrying amount of the financial asset unless the financial asset is credit-impaired, in which case interest income is calculated based on amortised cost of the financial asset. The Group recognises an impairment gain or loss in profit or loss for all financial instruments by adjusting their carrying amount. 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.
