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) (v) 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. Generally, the ECL is the difference between all contractual cash flows that are due to the Group in accordance with the contract and the cash flows that the Group expects to receive, discounted at the effective interest rate determined at initial recognition. Lifetime ECL for trade receivables are considered on a collective basis taking into consideration past due information and relevant credit information such as forward-looking macroeconomic information. For collective assessment, the Group takes into consideration the following characteristics when formulating the grouping: • Past-due status; • Nature, size and industry of debtors; and • External credit ratings where available. The grouping is regularly reviewed by management to ensure the constituents of each group continue to share similar credit risk characteristics.
