| Investment properties are held either at cost less any impairment or at revalued amount, depending on
the circumstances of acquisition and management intention. The directors assess the appropriate
measurement basis for each property individually.
Cost: Properties acquired during the year are stated at cost, including directly attributable acquisition
costs such as legal and professional fees. These assets are not depreciated, as the directors consider
the residual value to be equal to or greater than the carrying amount, and the useful economic life is not
reliably determinable.
Revaluation: Where properties are held at revalued amounts, they are stated at fair value as determined
by an independent valuation or director assessment at the balance sheet date. Changes in fair value
are recognised in the profit and loss account as they arise.
The directors review the carrying values of investment properties annually and adjust for any indication
of impairment or change in fair value.
Other tangible fixed assets are measured at cost less accumulative depreciation and any accumulative
impairment losses. Depreciation is provided on all tangible fixed assets, other than investment
properties, at rates calculated to write off the cost, less estimated residual value, of each asset
evenly over its expected useful life, as follows: |
