CIRD10220 - Intangible assets: introduction: fungible assets
Some assets are of a type that can be dealt in without identifying the particular assets involved. Examples would include some agricultural production rights arising from EU rules, such as milk quota. A holding of a number of identical units of a fungible asset count as a single asset for the purposes of the corporate intangible assets regime.
There are special commencement rules for fungible assets to ensure that additional units of a type of asset already held at 1 April 2002 can come within the regime, in spite of the general rule mentioned above, and to counter attempts to turn pre-FA 2002 assets outside the regime into assets within the regime by sale and repurchase. See CIRD11760 onwards.
