Sunny Optical Technology (Group) Company Limited • INTERIM REPORT 2021 84 Notes to the Condensed Consolidated Financial Statements 簡明綜合財務報表附註 FOR THE SIX MONTHS ENDED 30 JUNE 2021 截至二零二一年六月三十日止六個月 21. IMPAIRMENT ASSESSMENT ON TRADE RECEIVABLES SUBJECT TO EXPECTED CREDIT LOSS MODEL (Continued) The basis of determining the inputs and assumptions and the estimation techniques used in the condensed consolidated financial statements for the six months ended 30 June 2021 were the same as those followed in the preparation of the Group’s annual financial statements for the year ended 31 December 2020. The estimated loss rates are estimated based on historical observed default rates over the expected life of the debtors and are adjusted for forward-looking information that is available without undue cost or effort. The grouping is regularly reviewed by management to ensure relevant information about specific debtors is updated. As at 30 June 2021, the impairment allowance was provided in the amount of RMB110,395,000, among which RMB21,928,000 was made based on the provision matrix with life time ECL (not credit-impaired) and RMB88,467,000 was assessed individually on the debtors credit-impaired. 22. TIME DEPOSITS/PLEDGED BANK DEPOSITS/SHORT TERM FIXED DEPOSITS/BANK BALANCES AND CASH The time deposits carry fixed interest rates ranging from 3.85% to 4.18% (31 December 2020: 3.85% to 4.18%) per annum. The original maturity period of these time deposits is three years and are therefore classified as non-current assets. The Group pledged certain of its bank deposits to banks as security for note payables. Short term fixed deposits carry fixed interest rate ranging from 1.30% to 2.75% (31 December 2020: 1.92% to 3.15%) per annum. Short term fixed deposits have original maturity dates ranging from three months to one year and are therefore classified as current assets.
