5.4 Amortised cost measurement (paras. 5.4.1-5.4.9)
Financial assets
Effective interest method
5.4.1 Interest revenue shall be calculated by using the effective interest method (see Appendix A and paragraphs B5.4.1-B5.4.7). This shall be calculated by applying the effective interest rate to the gross carrying amount of a financial asset except for:
(a) purchased or originated credit-impaired financial assets. For those financial assets, the entity shall apply the credit-adjusted effective interest rate to the amortised cost of the financial asset from initial recognition.
(b) financial assets that are not purchased or originated credit-impaired financial assets but subsequently have become credit-impaired financial assets. For those financial assets, the entity shall apply the effective interest rate to the amortised cost of the financial asset in subsequent reporting periods.
