Explanation:

An intangible asset is an asset that lacks physical substance; in contrast to physical assets, such as machinery and buildings, and financial assets such as government securities. An intangible asset is usually very hard to evaluate. Examples are patents, copyright, franchises, goodwill, trademarks, and trade names. The general interpretation also includes software and other intangible computer based assets; these are all examples of intangible assets. Intangible assets generally—though not necessarily—suffer from typical market failures of non-rivalry and non-excludability.
