Bobble Limited prepares its accounts to 31 December each year. It purchased a building in January 2010 for 600,000. It determined that the building would have a useful life of 60 years with no residual value. In January 2016, the company decided to revalue the building and account for it on the revaluation basis. A professional valuer valued the building at 810,000. The revaluation was accounted for using the elimination method. No other assets have been revalued.
