Trade and other receivables are presented after deduction of impairment losses. No material impairment losses have been deducted from the amounts still to be invoiced on concluded projects. The write-down for expected bad debts is recognised in the statement of profit or loss under administrative expenses. At year-end 2023, the Group set aside a provision of € 0.8 million for the impairment of trade receivables (2022: € 0.6 million). For an analysis of the movements in this provision, see note 6.26 Financial risks and risk management.

Trade and other receivables are mainly short-term.
