177 2021 Annual Report Transport International Holdings Limited NOTES TO THE FINANCIAL STATEMENTS (Expressed in Hong Kong dollars unless otherwise indicated) 1 Significant accounting policies (continued) (n) Credit losses and impairment of assets (continued) (i) Credit losses from financial instruments (continued) Basis of calculation of interest income Interest income recognised in accordance with note 1(u)(iv) 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 the amortised cost (i.e. the gross carrying amount less loss allowance) of the financial asset. At each reporting date, the Group assesses whether a financial asset is credit-impaired. A financial asset is credit-impaired when one or more events that have a detrimental impact on the estimated future cash flows of the financial asset have occurred. Evidence that a financial asset is credit-impaired includes the following observable events: – significant financial difficulties of the debtor; – a breach of contract, such as a default or delinquency in interest or principal payments; – it becoming probable that the borrower will enter into bankruptcy or other financial reorganisation; – significant changes in the technological, market, economic or legal environment that have an adverse effect on the debtor; or – the disappearance of an active market for a security because of financial difficulties of the issuer. Write-off policy The gross carrying amount of a financial asset is written off (either partially or in full) to the extent that there is no realistic prospect of recovery. This is generally the case when the Group determines that the debtor does not have assets or sources of income that could generate sufficient cash flows to repay the amounts subject to the write-off. Subsequent recoveries of an asset that was previously written off are recognised as a reversal of impairment in profit or loss in the period in which the recovery occurs.
