The initial consolidation of Group companies takes place using the purchase method. This involves measuring the fair value of the assets, liabilities and contingent liabilities, identified in accordance with the provisions of IFRS 3, of the company acquired at the acquisition date, and allocating the acquisition costs to them. The proportion of fair value of assets and liabilities not acquired is shown under minority interests. Incidental acquisition costs are recognised as expenses.
Any excess of cost over the value of equity acquired is capitalised as goodwill and subject to a regular annual impairment test thereafter.
If the value of the acquirer’s interest in the shareholders’ equity exceeds the costs incurred by the acquiring company, the difference is recognised immediately in profit or loss.
Differences from minority interests acquired after control has been assumed are to be set off directly against equity.
Annual impairment tests applied to goodwill are carried out using recognised discounted cash flow methods. This is done on the basis of expected future cash flows from the latest management planning, which are extrapolated on the basis of long-term revenue growth rates and are assumptions with regard to margin development, and discounted for the capital costs of the business unit. Tests are performed at the cash generating unit (CGU) level. For the individual premises on which impairment tests were based in the financial year 2011, see .
Additional impairment tests are applied during the course of the year if events give reason to believe that goodwill could be permanently impaired.
