BASIS OF PREPARATION OF CONSOLIDATED FINANCIAL STATEMENTS AND MATERIAL ACCOUNTING POLICY INFORMATION (Continued) 3.2Ma t er i a l account i ng po l i cy i n forma t i on (Continued) Financial instruments (Continued) Financial assets (Continued) Impairment of financial assets subject to impairment assessment under HKFRS 9 (Continued) (iv) Write-off policy The Group writes off a financial asset when there is information indicating that the counterparty is in severe financial difficulty and there is no realistic prospect of recovery, for example, when the counterparty has been placed under liquidation or has entered into bankruptcy proceedings. Financial assets written off may still be subject to enforcement activities under the Group’s recovery procedures, taking into account legal advice where appropriate. A write-off constitutes a derecognition event. Any subsequent recoveries are recognised in profit or loss. (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 adjusted 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. The Group uses a practical expedient in estimating ECL on trade receivables using a provision matrix taking into consideration historical credit loss experience and forward looking information that is available without undue cost or effort. 3. 綜合財務報表之編製基準及 重大會計政策資料（續） 3.2 重大會計政策資料（續） 金融工具 （續） 金融資產（續） 須根據香港財務報告準則第 9 號進行減 值評估的金融資產之減值 （續） (iv) 撇銷政策 倘有資料顯示交易對手處於嚴重財 務困難及無實際期望可收回欠款， 本集團則撇銷該金融資產（例如於 交易對手被清盤或進入破產程序 時）。金融資產撇銷仍受限於本集 團收回欠款程序下的執行活動，且 在適當情況下將參考法律意見。撇 銷構成一項終止確認事項，任何其 後收回的欠款於損益內確認。 (v) 預期信貸虧損的計量及確認 預期信貸虧損計量是違約可能性、 違約損失率（即發生違約時的損失 程度）及違約風險的函數。違約可 能性及違約損失率的評定乃基於經 調整歷史數據及前瞻性資料。預期 信貸虧損的估算乃無偏頗及概率加 權的數額，其按相應違約風險的權 重釐定。本集團經考慮過往信貸虧 損經驗後使用撥備矩陣並採用實際 權益法估計貿易應收款項的預期信 貸虧損，並按無需花費不必要成本 或精力可取得的前瞻性資料。
