Consolidation principles

The separate financial statements of all companies included in consolidation are prepared in accordance with the uniform accounting policies that are applied within the Aurubis Group. The financial statements of the main companies included in the consolidated financial statements have been audited by independent auditors.

Capital consolidation is performed as at the acquisition date using the acquisition method, whereby the acquisition cost of the acquired interest is offset against the fair values of acquired assets and liabilities of the subsidiary at that time. Any unallocated difference on the asset side is recognized as goodwill and tested at least annually for impairment. In accordance with IAS 36, goodwill is not amortized on a scheduled basis. Negative goodwill is recognized immediately in profit or loss following a reassessment of the fair values.

Receivables, liabilities and contingent liabilities, and revenues, other income and expenses between group companies are eliminated. Profits resulting from transactions between group companies are eliminated, if material.

In addition to eight German companies, 15 foreign companies are included in the consolidated financial statements. In accordance with the functional currency concept, the financial statements of subsidiaries prepared in foreign currencies were translated into euros, as the euro is Aurubis AG’s reporting currency. Transactions in foreign currencies are converted into the functional currency at the exchange rate at the time of the transaction or, in the case of subsequent measurement, at the time of such measurement. Foreign currency transactions are primarily designated in US dollars. The average US dollar exchange rate during fiscal year 2015/16 was 1.11091 US$/€. The exchange rate as at September 30, 2016 was 1.1161 US$/€. Gains and losses resulting from the fulfillment of such transactions as well as from the conversion of monetary assets and liabilities designated in a foreign currency as at the balance sheet date are recorded in profit and loss in the cost of materials unless they have to be accounted for in equity as qualified cash flow hedges or net investments in foreign business operations. In fiscal year 2015/16, foreign currency conversion differences totaling € 1.9 million (net) were recognized as an expense. In accordance with IAS 21, assets and liabilities in the balance sheets of subsidiaries reporting in a foreign currency are translated at the mid-market rates on the balance sheet date and the income statement is translated at the average rates for the fiscal year. Any resultant translation differences are recognized directly in equity until the possible disposal of the subsidiary.

Joint ventures are accounted for in accordance with IFRS 11 using the equity method. Profits deriving from upstream/downstream transactions with Group companies are eliminated proportionally.
