FOR THE YEAR ENDED 31 DECEMBER 2020 截至二零二零年十二月三十一日止年度 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS 綜合財務報告附註 183 2020 ANNUAL REPORT 年報 4 重大會計估計和判斷 （續） (a) 所得稅及遞延稅項 （續） 當管理層認為將來很有可能有應課 稅溢利以扺銷暫時性差額或可使用 稅務虧損時，有關若干暫時性差額 及稅務虧損的遞延稅項資產予以確 認。實際使用的結果可能不同。 (b) 物業、廠房及設備及土地使用權 減值評估 當任何事件或情況變化顯示賬面值 可能無法收回時，物業、廠房及設 備及土地使用權會進行減值檢討。 可收回金額乃根據使用價值計算或 公平值減銷售成本之較高者釐定。 計算需要使用判斷和估計。資產減 值部分需要管理層的判斷進行，特 別是在評估時： (i) 是否發生了可能 表明相關資產價值無法收回的事 件； (ii) 資產的賬面值是否可以由可 收回金額支援，即公平值減去出售 成本與未來現金流量淨現值之間的 較高者，而該等現金流量乃根據業 務持續使用該資產而估計；及 (iii) 在 編制現金流量預測時應採用的適當 關鍵假設，包括這些現金流量預測 是否以適當的利率貼現。管理層在 評估減值時更改所選擇的假設，包 括現金流量預測中的鋼簾線價格年 增長率或貼現率的假設，可能會影 響減值測試中使用的淨現值，從而 影響本集團的財務狀況和營運業績。 4 CRITICAL ACCOUNTING ESTIMATES AND JUDGEMENTS (continued) (a) Income taxes and deferred taxation (continued) Deferred tax assets relating to certain temporary differences and tax losses are recognised when management considers it is probable that future taxable profit will be available against which the temporary differences or tax losses can be utilised. The outcome of their actual utilisation may be different. (b) Impairment assessments of property, plant and equipment and land use rights Property, plant and equipment and land use rights are reviewed for impairment whenever events or change in circumstances indicate that the carrying amounts may not be recoverable. The recoverable amounts have been determined based on the higher of value-in-use calculations or fair value less costs to sell calculations. The calculations require the use of judgements and estimates. Management’s judgement is required in the area of asset impairment particularly in assessing: (i) whether an event has occurred that may indicate that the related asset values may not be recoverable; (ii) whether the carrying amount of an asset can be supported by the recoverable amount, being the higher of fair value less costs to sell and net present value of future cash flows which are estimated based upon the continued use of the asset in the business; and (iii) the appropriate key assumptions to be applied in preparing cash flow projections including whether these cash flow projections are discounted using an appropriate rate. Changing the assumptions selected by management in assessing impairment, including the rate of annual increment for the steel cord price or the discount rates assumptions in the cash flow projections, could affect the net present value used in the impairment test and as a result affect the Group’s financial position and results of operations.
