Tangible assets are initially recorded at cost and are subsequently stated at cost less any accumulated depreciation and accumulated impairment losses.
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, 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 capital and reserves in respect of that asset. Where a revaluation decrease exceeds the accumulated revaluation gains accumulated in capital reserves of that asset, the excess shall be recognised in profit or loss.
