SECTION 2.3  Impairment 2.3.2  Impairment test of goodwill  and trademarks GOODWILL TRADEMARKS WITH INDEFINITE USEFUL LIFE The impairment test of goodwill is per- formed for Western Europe and Eastern  Europe, while entities in Asia are tested at sub-regional levels. Entities that are less  integrated in regions or sub-regions are  tested at individual entity level.  Management of the Group is centralised and driven through the regional manage- ments, which are responsible for perfor- mance, investments and growth initiatives  in their respective regions. The management  structure and responsibilities support and  promote optimisations across countries  focusing on the Group or region as a whole  and not just on the specific country. Changes  in procurement and sourcing between coun- tries increase intra-Group trade/transactions,  which will also have an increasing impact on  the allocation of profits.  Trademarks are impairment-tested individu- ally at Group level. The carrying amount of  trademarks which have an indefinite useful  life and therefore are not amortised was  DKK 32,191m (2012: DKK 35,395m) at 31 De- cember 2013, equivalent to 98% (2012: 99%)  of the capitalised trademarks. Management  assesses that the value of these trademarks  can be maintained for an indefinite period,  as these are well-established trademarks in  the markets concerned and these markets  are expected to be profitable in the long  term. In the opinion of management, there  is only a minimal risk of the current situa- tion in the markets reducing the useful life  of these trademarks, primarily due to the  respective market share in each market and  the current and planned marketing efforts,  which are helping to maintain and increase  the value of these trademarks. For the Group’s cash-generating units, the  carrying amount of goodwill and trademarks  with indefinite useful life at 31 December is  summarised to the right. Goodwill and trademarks with indefinite use- ful life related to Baltika Breweries (Russia),  Brasseries Kronenbourg (France) and the  acquisition of the 40% non-controlling inter- est in Carlsberg Breweries A/S each comprise  10% or more of the total carrying amount of  goodwill and trademarks with an indefinite  useful life at 31 December 2013.
