* Operating surplus and other earnings figures that are affected by the implementation of IFRS 16 are recognised in the comments for comparisons between the periods exclusive of the effects of the implementation of IFRS 16. This means that earnings figures, such as operating surplus, in the comments differ from the figures in the income statement. The effect of the implementation of IFRS 16 has resulted in the leasehold fees for 2019 being recognised in net financial items instead of being included in property management costs. All of the key ratios for 2019 have been calculated exclusive of the effects of the implementation of IFRS 16. See the Interim report for full key ratios and definitions.
