Revaluation model for intangible assets

After initial recognition, the IAS 38 revaluation model carries an intangible asset at its revalued amount, being fair value at revaluation less subsequent accumulated amortisation and impairment. Fair value for this model must be determined by reference to an active market, which is uncommon for intangible assets. Apply the model to the asset class unless no active market exists for an asset in that class, and revalue with sufficient regularity. The model does not permit initial recognition of an otherwise unrecognised intangible. An increase normally goes to other comprehensive income and revaluation surplus, except to the extent it reverses a previous decrease recognised in profit or loss; decreases have corresponding rules.
