Annual Report 2024

Notes to the Consolidated Financial Statements 綜合財務報表附註 FOR THE YEAR ENDED 31 DECEMBER 2024 截至二零二四年十二月三十一日止年度 204 Sunny Optical Technology (Group) Company Limited • ANNUAL REPORT 2024 4. KEY SOURCES OF ESTIMATION UNCERTAINTY (Continued) Fair value measurement of financial instruments As at 31 December 2024, certain of the Group’s financial instruments, including unlisted equity instruments amounting to RMB30,378,000 (2023: unlisted equity instruments amounting to RMB31,853,000) and foreign currency options contracts amounting to RMB33,263,000 (2023: RMB5,206,000) are measured at Level 3 fair values. In estimating the fair value, the Group uses market-observable data to the extent it is available. When market observable data are not available, the Group uses valuation techniques that include inputs that are not based on market-observable data to estimate the fair value of certain types of financial instruments. Note 36(c) provides detailed information about the valuation techniques, inputs and key assumptions used in the determination of the fair value of various financial assets and financial liabilities. Recognition of deferred tax assets As at 31 December 2024, a deferred tax asset of approximately RMB329,410,000 (2023: RMB285,890,000) in relation to unused tax losses for certain operating subsidiaries has been recognised in the Group’s consolidated statement of financial position as disclosed in Note 19. No deferred tax asset has been recognised on the tax losses of RMB4,572,315,000 (2023: RMB4,449,883,000) either due to the unpredictability of future profit streams. The realisability of the deferred tax asset mainly depends on whether sufficient taxable profits will be available in the future or taxable temporary differences are expected to reverse in the same period as the expected reversal of the deductible temporary differences, which is a key source of estimation uncertainty. The uncertainty would depend on how the ongoing uncertain macroeconomic and geopolitical environment, which includes the persistent effects of higher interest rates and inflation, elections in major economies, and international conflicts and tensions, may progress and evolve. In cases where the actual future taxable profits generated are less or more than expected, or change in facts and circumstances which result in revision of future taxable profits estimation, a material reversal or further recognition of deferred tax assets may arise, which would be recognised in profit or loss for the period in which such a reversal or further recognition takes place. 4. 估計不確定因素的主要來源 （續） 金融工具公允值計量 於二零二四年十二月三十一日，若干本集 團的金融工具，包括非上市權益工具人民 幣 30,378,000 元（二零二三年：非上市權 益工具人民幣 31,853,000 元）及外匯期權 合約人民幣 33,263,000 元（二零二三年： 人民幣 5,206,000 元）乃按第三級公允值計 量。估算公允值時，本集團在可用範圍內 採用市場可觀察數據。倘市場可觀察數據 無法獲得，本集團使用估值技術（包括並非 根據市場可觀察數據的輸入數據）估計若干 類型金融工具之公允值。附註 36(c) 載有有 關釐定各項金融資產及金融負債公允值所 使用的估值技術、輸入數據及主要假設之 詳情。 確認遞延稅項資產 如附註 1 9 所披露，於二零二四年十二 月三十一日，就若干營運附屬公司的未 使用稅項虧損而言，已於本集團綜合財 務狀況表內確認遞延稅項資產約人民幣 3 2 9 , 4 1 0 , 0 0 0 元（二零二三年：人民幣 285,890,000 元）。因未來溢利流不可預 測，概無就稅項虧損人民幣 4,572,315,000 元（二零二三年：人民幣 4,449,883,000 元）確認遞延稅項資產。遞延稅項資產是否 可變現主要取決於日後是否會有足夠的應 課稅溢利或應課稅暫時差額是否預計會在 可抵扣暫時差額預期撥回的同一期間內撥 回，此乃估計不確定性的主要來源。該不 確定性取決於持續不確定的宏觀經濟及地 緣政治環境（包括較高的利率及通貨膨脹、 主要經濟體的大選以及國際衝突和緊張局 勢的持續影響）將如何發展和演變。倘實際 產生的未來應課稅溢利低於或超過預期， 或導致對未來應課稅溢利估計進行修訂的 事實及情況發生改變，則可能導致遞延稅 項資產出現重大撥回或未來確認，其將於 該撥回或未來確認發生期間於損益中確認。
