Significant Accounting Policies (Continued) Property, plant and equipment Property, plant and equipment including buildings held for use in the production or supply of goods or services, or for administrative purposes, other than construction in progress, are stated at cost less subsequent accumulated depreciation and accumulated impairment loss. Depreciation is provided to write off the cost of items of property, plant and equipment, other than construction in progress over their estimated useful lives and after taking into account of their estimated residual value, using the straight-line method. Construction in progress includes property, plant and equipment in the course of construction for production or for its own use purposes. Construction in progress is carried at cost less any recognised impairment loss. Construction in progress is classified to the appropriate category of property, plant and equipment when completed and ready for intended use. Depreciation of these assets, on the same basis as other property assets, commences when the assets are ready for their intended use. An item of property, plant and equipment is derecognised upon disposal or when no future economic benefits are expected to arise from the continued use of the asset. Any gain or loss arising on derecognition of the asset (calculated as the difference between the net disposal proceeds and the carrying amount of the item) is included in the consolidated income statement in the year in which the item is derecognised. Leasing Leases are classified as finance leases whenever the terms of the lease transfer substantially all the risks and rewards of ownership to the lessee. All other leases are classified as operating leases. The Group as lessee Rentals payable under operating leases are charged to profit or loss on a straight-line basis over the term of the relevant lease. Benefits received and receivable as an incentive to enter into an operating lease are recognised as a reduction of rental expense over the lease term on a straight-line method. 3. 主要會計政策（續） 物業、機器及設備 物業、機器及設備（包括持作生產或供應 貨品或服務或作行政用途的樓宇，在建 工程除外）按成本減累計折舊及累計減值 虧損列賬。 除在建工程外，物業、機器及設備折舊 （經計及估計剩餘價值）乃於估計可用年 期以直線法（作出減值撥備以撇銷其成 本）。 在建工程指正就生產或自用興建的物 業、機器及設備。在建工程按成本減任 何已確認減值虧損列賬。在建工程於完 成且可作擬定用途時，會列作物業、機 器及設備之適當類別。該等資產按與其 他物業資產相同之方式，於資產可作擬 定用途時開始折舊。 物業、機器及設備項目於出售後或預計 持續使用該資產不會於日後產生經濟利 益時取消確認。於取消確認該資產時產 生之任何損益（以該項目出售所得款項淨 額與賬面值的差額計算）於該項目取消確 認的年度計入綜合收益表。 租約 當租約條款將絕大部份風險及回報轉讓 予承租人時，該租約分類為融資租約。 所有其他租約均分類為經營租約。 本集團作為承租人 根據經營租約的應付租金，於有關租期 內以直線法在損益中扣除。作為訂立經 營租約獎勵的已收及應收利益，按直線 法於租期內確認為租金開支減少。
