pre_text: The actual return on plan assets amounted to €125 million in the reporting period (2017/ 18: €45 million). For financial year 2019/20, the company expects employer payments to external pension providers totalling approximately €18 million and employee contributions of €9 million in plan assets, with contributions in the Netherlands, Belgium and Germany accounting for the major share of this total. Expected contributions from payment contribution commitments in Germany are not included in expected payments. The fair value of plan assets developed as follows: At one Dutch company, plan assets exceeded the value of commitments as of the closing date. Since the company cannot draw any economic benefits from this overfunding, the balance sheet amount was reduced to €0 in line with IAS 19.64 (b).
