(1) The 2018 figures have been adjusted to take account of the interpretations of the International Financial Reporting Interpretations Committee (IFRIC) contained in the Agenda Decision of March 2019, which involved changes in the classification, with no impact on margins, of the effects of purchase and sales contracts for commodities measured at fair value through profit or loss (for more details, see note 4.3 of the consolidated financial statements).
Other operating expenses increased by €5,507 million mainly due to the reclassifications in response to the IFRIC Agenda Decision of March 2019 concerning the recognition of non-financial transactions with physical delivery within the scope of IFRS 9. For more information, see paragraph 4.3 of the notes to the consolidated financial statements.
