Tangible assets are initially measured at cost, and are subsequently measured at cost less any
accumulated depreciation and accumulated impairment losses or at a revalued amount.
Any tangible assets carried at a revalued amount are recorded at the fair value at the date of revaluation
less any subsequent accumulated depreciation and subsequent accumulated impairment losses.
An increase in the carrying amount of an asset as a result of a revaluation is recognised in other
comprehensive income and accumulated in capital and reserves. However, the increase is recognised
in profit or loss to the extent that it reverses a revaluation decrease of the same asset previously
recognised in profit or loss. A decrease in the carrying amount of an asset as a result of revaluation
is recognised in other comprehensive income to the extent of any previously recognised revaluation
increase accumulated in capital and reserves. If a revaluation decrease exceeds the accumulated
revaluation gains accumulated in capital and reserves in respect of that asset, the excess is recognised
in profit or loss.
Depreciation is calculated so as to write off the cost of an asset, less its estimated residual value, over
the useful economic life of that asset as follows:
