According to the International Accounting Standards, an intangible asset is an identifiable non-monetary asset without physical substance.
The definition of an intangible asset requires an intangible asset to be identifiable to distinguish it from goodwill. Goodwill acquired in a business combination represents a payment made by the acquirer in anticipation of future economic benefits from assets that are not capable of being individually identified and separately recognised. The future economic benefits may result from synergy between the identifiable assets acquired or from assets that, individually, do not qualify for recognition in the financial statements but for which the acquirer is prepared to make a payment in the business combination.
