Tangible assets are initially recorded at cost, and subsequently stated at cost less any accumulated
depreciation and impairment losses. Any tangible assets carried at revalued amounts 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 equity, except to the extent 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 equity in respect of that asset. Where a
revaluation decrease exceeds the accumulated revaluation gains accumulated in equity in respect of
that asset, the excess shall be recognised in profit or loss.
