HONG KONG HOUSING SOCIETY ANNUAL REPORT 2020/21
2.4 Summary of significant accounting policies
(continued)
Fair value measurement (continued)
For assets and liabilities that are recognised in the financial statements on a recurring basis, the Housing Society determines whether transfers have occurred between levels in the hierarchy by reassessing categorisation (based on the lowest level input that is significant to the fair value measurement as a whole) at the end of each reporting period.
Impairment of non-financial assets
Where an indication of impairment exists, or when annual impairment testing for an asset is required (other than financial assets), the asset’s recoverable amount is estimated. An asset’s recoverable amount is the higher of the asset’s or cash-generating unit’s value in use and its fair value less costs of disposal, and is determined for an individual asset, unless the asset does not generate cash inflows that are largely independent of those from other assets or group of assets, in which case the recoverable amount is determined for the cash-generating unit to which the asset belongs.
An impairment loss is recognised only if the carrying amount of an asset exceeds its recoverable amount. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset. An impairment loss is charged to the comprehensive income in the period in which it arises in those expense categories consistent with the function of the impaired asset.
An assessment is made at the end of each reporting period as to whether there is an indication that previously recognised impairment losses may no longer exist or may have decreased. If such an indication exists, the recoverable amount is estimated. A previously recognised impairment loss of an asset other than goodwill is reversed only if there has been a change in the estimates used to determine the recoverable amount of that asset, but not to an amount higher than the carrying amount that would have been determined (net of any depreciation/amortisation) had no impairment loss been recognised for the asset in prior years. A reversal of such an impairment loss is credited to the comprehensive income in the period in which it arises.
2.4 主要會計政策概要(續) 公允值計量(續)
就按經常性於本財務報表確認的資產及 負債而言，房屋協會透過於各報告期末 重新評估分類(基於對公允值計量整體 而言屬重大的最低層輸入數據)確定是 否發生不同等級轉移。
非財務資產減值
倘有跡象顯示出現減值或要求就資產進 行 年 度 減 值 測 試( 財 務 資 產 除 外 )， 則 會 估計該資產的可收回金額。資產的可收 回金額按資產或現金產生單位的使用價 值及其公允值減出售成本(以較高者為 準)，並就個別資產而釐定，除非有關 資產並無產生在頗大程度上獨立於其他 資產或資產組別的現金流入，在此情況 下可收回金額就資產所屬的現金產生單 位而釐定。
減值虧損僅於資產賬面值超出其可收回 金額時予以確認。於評估使用價值時， 估計日後現金流量按可反映現時市場評 估的貨幣時間值及資產特定風險的稅前 折現率折減至現值。減值虧損乃於產生 期間計入全面收益內與已減值資產功能 一致之開支項目內。
於各報告期末會評定是否有跡象顯示之 前已確認的減值虧損不再存在或減少。 倘出現該跡象，則會估計可收回金額。 過 往 確 認 的 資 產( 商 譽 除 外 )減 值 虧 損 僅 在用以釐定該項資產可收回金額的估計 改變時撥回，惟撥回後的數額不得高於 假設過往年度並無就資產確認減值虧損 而 應 有 的 賬 面 值( 扣 除 折 舊 ╱ 攤 銷 後 )。 減值虧損的撥回於產生期間計入全面收 益。
