While depreciation and amortisation increased by CHF 2.4 million, depreciation and amortisation resulting from business combinations declined by CHF 4.5 million, mainly due to changes to the group of consolidated companies (effect of CHF 2.9 million).

Based on a goodwill impairment test, no requirement for any impairment on goodwill was identified. In the previous year, an impairment on goodwill of CHF 85.0 million was recorded for the cash-generating unit Tamedia. See Note 22 “Goodwill and intangible assets with an indefinite useful life”.
