SIGNIFICANT ACCOUNTING POLICIES (Continued) Impairment on tangible, right-of-use assets and intangible assets other than goodwill (Continued) Where an impairment loss subsequently reverses, the carrying amount of the asset (or cash generating unit or a group of cash- generating units) is increased to the revised estimate of its recoverable amount, but so that the increased carrying amount does not exceed the carrying amount that would have been determined had no impairment loss been recognised for the asset (or cash-generating unit or a group of cash-generating units) in prior years. A reversal of an impairment loss is recognised immediately in profit or loss. Inventories Inventories are stated at the lower of cost and net realisable value. Costs of inventories are determined on a weighted average method. Net realisable value represents the estimated selling price for inventories less all estimated costs of completion and costs necessary to make the sale. Financial instruments Financial assets and financial liabilities are recognised when a group entity becomes a party to the contractual provisions of the instrument. All regular way purchases or sales of financial assets are recognised and derecognised on a trade date basis. Regular way purchases or sales are purchases or sales of financial assets that require delivery of assets within the time frame established by regulation or convention in the market place. Financial assets and financial liabilities are initially measured at fair value except for trade receivables arising from contracts with customers which are initially measured in accordance with HKFRS 15. Transaction costs that are directly attributable to the acquisition or issue of financial assets and financial liabilities (other than financial assets or financial liabilities at FVTPL) are added to or deducted from the fair value of the financial assets or financial liabilities, as appropriate, on initial recognition. Transaction costs directly attributable to the acquisition of financial assets or financial liabilities at FVTPL are recognised immediately in profit or loss. 3. 重要會計政策（續） 有形資產、使用權資產及無形資產 （商譽除外）減值（續） 倘減值虧損於其後撥回，則該項資產（或現 金產生單位或現金產生單位組別）之賬面值 會增加至其經修訂之估計可收回金額，惟 增加後之賬面值不得超出假設過往年度並 無就該項資產（或現金產生單位或現金產 生單位組別）確認減值虧損原應釐定之賬面 值。減值虧損撥回即時於損益中確認。 存貨 存貨按成本及可變現淨值的較低者列賬。 存貨成本按加權平均法釐定。可變現淨值 指存貨估計售價減直至完工的全部估計成 本及銷售活動所需成本。 金融工具 當集團實體成為工具合約條文的訂約方 時，金融資產及金融負債方獲確認。所有 以正規途徑購買或銷售之金融資產乃按交 易日期基準確認及取消確認。正規途徑買 賣或銷售乃要求於市場法規或慣例所確定 之時間框架內交付資產之金融資產買賣或 銷售。 金融資產及金融負債初步按公允值計量， 惟根據香港財務報告準則第 15 號初步計量 的與客戶合約產生的貿易應收款項除外。 交易成本直接歸屬於收購或發行金融資產 及金融負債（按公允值計入損益的金融資產 或金融負債除外），在初始確認時適當地計 入或自金融資產或金融負債的公允值中扣 除。直接歸屬於收購按公允值計入損益的 金融資產或金融負債的交易成本，即時於 損益中確認。
