Tangible fixed assets under the cost model are stated at historical cost less accumulated depreciation and any accumulated impairment losses. Historical cost includes expenditure that is directly attributable to bringing the asset to the location and condition necessary for it to be capable of operating in the manner intended by management.
The assets' residual values, useful lives and depreciation methods are reviewed and adjusted prospectively if appropriate, or if there is an indication of a significant change since the last reporting date.
Gains and losses on disposals are determined by comparing the proceeds with the carrying value amount and are recognised in the Income Statement.
