‘Other operating expenses’ include insurance, accommodation costs, costs of fixtures and fittings, auditor’s fees, marketing costs, maintenance costs for operating assets and additions to provisions. The decrease in other operating expenses from €1,046 million in 2018 to €738 million in 2019 was mainly attributable to the application of IFRS 16 (no longer any lease costs in 2019).
