Other impairments of property, plant and equip- ment are a consequence of restructuring and  process optimisations, especially in Western  Europe and Eastern Europe. In 2012 there were recognised impairments of Carlsberg Uzbekistan, DKK 91m in total,  Nordic Getränke, Germany, DKK 64m, and  Vena Brewery, production and sales equip- ment, Russia, DKK 589m. The impairments  related to intangible assets and property,  plant and equipment and were a consequence  of difficult market conditions and poor per- formance. The Sarbast trademark was fully  impaired as part of the DKK 91m impairment  of Carlsberg Uzbekistan in 2012.  The impairment of plant, machinery and equipment in Ringnes, Norway, is a conse- quence of the switch to one-way recyclable  packaging, cf. section 3. Impairment of  plant, machinery and equipment in other  markets is a consequence of difficult market  conditions.  The Carlsberg Group performs annual im- pairment tests to verify the value of recog- nised goodwill, trademarks and other non- current assets. In connection with impairment testing manage- ment reassesses the useful life and residual  value of assets with impairment indicators. Based on the impairment tests performed,  the Group has recognised impairment losses  totalling DKK 375m in respect of trademarks  and other non-current assets. The impairment losses on trademarks (indefi- nite and finite) in 2013 related partly to local  trademarks in Russia (Nevskoye) and Kazakh- stan (Derbes) that have suffered from the eco- nomic crisis and changes in the brand strategy  and therefore showed a recoverable amount be- low the carrying amount. The trademarks were  therefore written down to the lower recoverable  amount. A local trademark in France (Kanter- brau) and local trademarks with finite useful life  in Estonia were also impaired due to changes in  the brand strategy in these two markets.
