3. Significant accounting estimates
The preparation of the Housing Society’s financial statements requires management to make estimates and assumptions that affect the reported amounts of revenues, expenses, assets and liabilities, and their accompanying disclosures, and the disclosure of contingent liabilities. Uncertainty about these assumptions and estimates could result in outcomes that could require a material adjustment to the carrying amounts of the assets or liabilities affected in the future.
Estimation uncertainty
The key assumptions concerning the future and other key sources of estimation uncertainty at the end of the reporting period, that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year, are described below.
Impairment of non-financial assets
The Housing Society assesses whether there are any indicators of impairment for all non-financial assets at the end of each reporting period and they are tested for impairment when there are indicators that the carrying amounts may not be recoverable. An impairment exists when the carrying value of an asset or a cash-generating unit exceeds its recoverable amount, which is the higher of its fair value less costs of disposal and its value in use. The calculation of the fair value less costs of disposal is based on available data from binding sales transactions in an arm’s length transaction of similar assets or observable market prices less incremental costs for disposing of the asset. When value in use calculations are undertaken, management must estimate the expected future cash flows from the asset or cash-generating unit and take into account of certain key assumptions including the budgeted rental price, growth rate, estimated construction costs to complete and choose a suitable discount rate in order to calculate the present value of those cash flows.
3. 主要會計估計
編制房屋協會的財務資料時，管理層須 於報告日作出會影響所呈報收益、開 支、資產與負債的報告金額及其披露以 及或然負債披露的判斷、估計及假設。 有關該等假設及估計的不明朗因素可能 導致可能須對日後受到影響的資產與負 債的賬面值作出重大調整。
估計的不明朗因素
下文為於報告日有關未來的主要假設及 其他主要估計的不明朗因素，其涉及導 致下個財政年度對資產及負債賬面值作 出重大調整的重大風險。
非財務資產減值
房屋協會評估各報告期末是否存在所有 非財務資產的減值跡象，並在有跡象顯 示賬面值可能無法收回時進行減值測 試。倘資產或現金產生單位的賬面值超 過其可收回金額(即其公允值減出售成 本及其使用價值兩者中的較高者)，則 存在減值。公允價值減出售成本的計算 基於公平交易中具有類似資產的約束性 銷售交易的可用數據或可觀察市場價格 減去處置該資產的增量成本。當進行使 用價值計算時，管理層必須估計資產或 現金產生單位的預期未來現金流量，以 及考慮若干主要假設包括預算租金、增 長率及估計建築成本，並選擇合適的折 現率以計算該等現金流量的現值。
