IBAN’s mandate is to assure the Council and the governments of NATO member countries that funds have been used according to authorization and that the financial statements are accurate and give a fair view of NATO’s financial situation. IBAN also evaluates NATO’s activities with regard to their economy, efficiency, and effectiveness.In order to achieve this mandate, IBAN performs 3 types of audits:

  • Performance audit: an evaluation of the economy, efficiency, and effectiveness of NATO's activities, operations and programmes;

  • NSIP financial audit: an examination of expenditures for these projects, which relate to, for example, infrastructure, equipment or information and communication systems.
