Intangible assets are initially measured at cost and are subsequently measured at cost less any accumulated amortisation and accumulated impairment losses or at a revalued amount. However, Intangible assets acquired as part of a business combination are only recognised separately from goodwill when they arise from contractual or other legal rights, are separable, the expected future economic benefits are probable and the cost or value can be measured reliably.
Any intangible assets carried at a revalued amount are recorded at the fair value at the date of revaluation, as determined by reference to an active market, less any subsequent accumulated amortisation 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.
