BASIS OF PREPARATION OF CONSOLIDATED FINANCIAL STATEMENTS AND SIGNIFICANT ACCOUNTING POLICIES (Continued) 3.2 Significant accounting policies (Continued) Financial instruments (Continued) Financial assets (Continued) Impairment of financial assets (Continued) (i) Significant increase in credit risk (Continued) Despite the aforegoing, the Group assumes that the credit risk on a debt instrument has not increased significantly since initial recognition if the debt instrument is determined to have low credit risk at the reporting date. A debt instrument is determined to have low credit risk if i) it has a low risk of default, ii) the borrower has a strong capacity to meet its contractual cash flow obligations in the near term and iii) adverse changes in economic and business conditions in the longer term may, but will not necessarily, reduce the ability of the borrower to fulfil its contractual cash flow obligations. The Group considers a debt instrument to have low credit risk when it has an internal or external credit rating of ‘investment grade’ as per globally understood definitions. The Group regularly monitors the effectiveness of the criteria used to identify whether there has been a significant increase in credit risk and revises them as appropriate to ensure that the criteria are capable of identifying significant increase in credit risk before the amount becomes past due. 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） 金融資產減值（續） (i) 信貸風險大幅上升（續） 儘管有上述規定，倘債務工具於報 告日期釐定為低信貸風險，本集團 假定該債務工具信貸風險自初步確 認以來並無大幅上升。一項債務工 具倘 i ）其違約風險低； ii) 借款人有 很強的能力在短期內履行其近期合 約現金流量責任；及 iii ）經濟及業 務狀況較長遠的不利變化，（但非 必然會）減低借款人履行其合約現 金流量責任的能力，則將被釐定為 低信貸風險。倘一項債務工具的內 部或外部信貸評級為「投資評級」 （根據全球理解的定義），本集團認 為其信貸風險為低。 本集團定期監察用以識別信貸風險 有否大幅上升的標準的成效，並且 適時作出修訂，以確保該標準能夠 於有關款額逾期前識別信貸風險大 幅上升。
