In practice intangible assets can refer to different things, but are generally used to mean economic assets which do not have physical substance or form, or are not tangible. Intangible assets include brands, goodwill, customer relationships, software and intellectual property related rights. We have compiled on this website a list of intangible assets. Intangible asset valuations are used, in particular,  in accounting practice to recognise assets on business combinations at fair values, which is aimed at improving acquisition accounting transparency.
