The assets within patent rights include the rights to Equidone® which was launched in the USA during 2011, and has a carrying value of £0.1 million with a remaining amortisation period of 1 year, and the in-licensed products within Canada (acquired in 2016 with a carrying value of £0.2 million and has a remaining amortisation period of 6.5 years). During the year, £0.3 million was added to patent rights within EU Pharmaceuticals Segment.

£0.8 million of the marketing authorisations relate to the Vetivex range of products. Ownership of the marketing authorisations rests with the Group in perpetuity. There are not believed to be any legal, regulatory or contractual provisions that limit their useful lives. Vetivex is an established range of products which are relatively simple in nature and there are a limited number of players in the market. Accordingly, the Directors believe that it is appropriate that the marketing authorisations are treated as having indefinite lives for accounting purposes.

The software intangible asset includes £10.5 million relating to the ERP system in the EU Pharmaceuticals Segment, this has a remaining amortisation period of 5 years.

Goodwill is allocated across cash generating units that are expected to benefit from that business combination. Key assumptions made in this respect are given in note 14.
