Goodwill is not amortised, but tested annually for impairment with the recoverable amount being determined from value in use calculations. Goodwill has been allocated for impairment testing purposes to groups of cash-generating units (CGUs) which include the combined retail and wholesale businesses for each location.
Brands consist of the per una brand cost of £80.0m and the M&S Mode brands of £32.4m. The per una brand is a definite life intangible asset and is amortised on a straight-line basis over a period of 15 years and is only assessed for impairment where such indicators exist. The M&S Mode brands have been attributed an indefinite life as they give the Group the future right to use the ‘M&S’ brand across Europe. This is consistent with the Group’s expansion plans in Europe and exising M&S brand recognition from its current presence. Similar to goodwill, the M&S Mode brands are assessed for impairment annually based on their value in use. The M&S Mode brands have been allocated for impairment testing across the European business.
