The consolidated financial statements are presented in euros. The euro is the currency of the primary business environment (functional currency) of all companies included in the consolidated financial statements. In the single-entry financial statements of the parent and of the consolidated subsidiaries, business transactions in foreign currencies are translated into the functional currency at the exchange rate prevailing on the date of the transaction. Gains and losses arising on the fulfilment of such transactions and on the translation of monetary assets and liabilities carried in foreign currencies using the exchange rate prevailing at the end of the reporting period are recognised in profit or loss.
