31. Service fees to external auditors

The service fees to external auditors consists of:

The costs for audit of the finanial statements (i.e., all audit costs that are incurred to audit the financial statements for the respective financial year are allocated to the financial year to which the financial statements relate) and other audit engagements were invoiced by Deloitte Accountants B.V. The other non‑audit service costs were invoiced by another Deloitte network. The audit committee approved the other services charged by Deloitte.
Deloitte did not provide any tax advisory related services in either year.
