Key money

Key money as part of intangible assets has an indefinite useful life, relating to stores in France and Brazil. These assets are not amortized but are subject to an annual impairment test using cash flow projections covering a five-year period and the market value is used based on external valuations. Details as to the cost per square meter and latest key money transactions for the main shopping malls are publicly available.

If the calculated value in use is less than the carrying value of the assets, external valuations are performed to arrive at a fair value less costs of disposal.

During 2017 the impairment test on key money resulted in an impairment in France and Brazil of €1,322 (2016: €1,860) as a result of a decrease in value in use and external valuations performed for each store individually.

The carrying amount of the key money with an indefinite useful life is tested on a store-by-store basis and per country amounts to:
