2.5 Property, plant and equipment Property, plant and equipment including land and buildings are stated at historical cost less depreciation. Historical cost includes expenditure that is directly attributable to the acquisition of the items. Subsequent costs are included in the asset's carrying amount or recognised as a separate asset, as appropriate, only when it is probable that future economic benefits associated with the item will flow to the Group and the cost of the item can be measured reliably. The carrying amount of the replaced part is de-recognised. All other repairs and maintenance are charged to the consolidated statement of profit or loss during the financial period in which they are incurred. Interest costs on borrowings to finance the construction of property, plant and equipment are capitalised during the period of time that is required to complete and prepare the asset for its intended use. Other borrowing costs are expensed. Land is not depreciated. Depreciation is provided on the straight-line basis at rates estimated to write-off the cost of each asset over its expected useful life. In the case of motor vehicles, depreciation is based on cost less an estimated residual value. The estimated useful lives of assets are reviewed periodically, taking account of commercial and technological obsolescence as well as normal wear and tear, and depreciation rates are adjusted if appropriate. Current rates of depreciation are: Freehold property Leasehold property and improvements Plant and equipment Rental assets Furniture and fixtures Motor vehicles 2% 2% to 20% 5% to 33.3% 25% 10% to 25% 10% to 25% The assets' residual values and useful lives are reviewed, and adjusted if appropriate, at each statement of financial position date. Leasehold property and improvements are depreciated over the shorter of the asset's useful economic life and the lease term. An asset's carrying amount is written down immediately to its recoverable amount if the asset's carrying amount is greater than its estimated recoverable amount. Gains and losses on disposals are determined by comparing the proceeds with the carrying amount and are included in the consolidated statement of profit or loss. Consolidated Statement of Cash Flows.
