Goodwill in the amount of 2,026 is related to the 2017 acquisition of a Natuzzi Mexico franchisee by the subsidiary Natmex S.DE.R.L.DE.C.V., as previously commented, and additionally in the amount of 1,921 is related to the 2016 acquisition of four “Divani&Divani by Natuzzi” stores, located in the North East of Italy. The latter acquisition was performed with a related party at arm’s length conditions.

Impairment tests have been performed on goodwill in 2018 and 2017. No impairment loss has been recorded as a result of the tests performed.

The key inputs and assumptions that were used in performing the 2018 and 2017 impairment tests for goodwill are as follows:


December, 2018 CGU	Net book value after impairment test		Growth rate			WACC			Sales CAGR 2019-2022

Italy – retail stores		1,921		0.5	%		11	%		6	%
Mexico – retail stores		2,026		0.5	%		18	%		8.5	%

Total goodwill		3,947


December, 2017 CGU	Net book value after impairment test		Growth rate			WACC			Sales CAGR 2018-2022

Italy – retail stores		1,921		0.5	%		10	%		5	%
Mexico – retail stores		1,925		0.5	%		17	%		8.5	%

Total goodwill		3,846

Further, the cash flows included specific estimates for five years and a terminal growth rate thereafter. The estimated recoverable amount of each CGU significantly exceeded its carrying amount.
