Interest income is calculated by applying the effective interest rate to the gross carrying amount of a financial asset, expect for financial assets that have subsequently become credit-impaired. For financial assets that have subsequently become credit-impaired, interest income is recognised by applying the effective interest rate to the amortised cost of the financial asset from the next reporting period. If the credit risk on the credit-impaired financial instrument improves so that the financial asset is no longer credit-impaired, interest income is recognised by applying the effective interest rate to the gross carrying amount of the financial asset from the beginning of the reporting period following the determination that the asset is no longer credit-impaired. 3. 綜合財務報表之編製基準及 重要會計政策（續） 3.2 重要會計政策（續） 金融工具（續） 金融資產（續） 金融資產的分類和其後計量（續） (i) 攤銷成本及利息收入 其後按攤銷成本計量的金融資產的 利息收入採用實際利率法確認。利 息收入按對金融資產的總賬面值應 用實際利率的方式計算，惟其後出 現信貸減值的金融資產除外。有關 其後出現信貸減值的金融資產，利 息收入自下個報告期起應用實際利 率法於按攤銷成本列賬的金融資產 確認。倘信貸減值金融工具的信貸 風險得以改善，使金融資產不再信 貸減值，則利息收入將透過於確定 資產不再信貸減值後的報告期間開 始起對金融資產賬面總值應用實際 利率確認。
