Reconciliation for the organic development of key figures for the prior-year comparative period
For the organic presentation of figures, prior-period comparatives are adjusted for the effects of changes in the composition of the Group, exchange rate effects, and other effects. This improves the informative value of the prior-year comparatives by taking account of changes to the company’s structure or exchange rates.
