The Inter-Agency Accountants’ Network (IAAN) Annual Meeting brings together accounting and financial management professionals from EU agencies to discuss accounting, financial reporting, audit, and financial systems developments. Hosted by the European Labour Authority (ELA) in Bratislava on 1–2 October 2026, the meeting includes participants from EU agencies responsible for accounting and finance. EIGE contributes to discussions on SUMMA implementation, audit challenges, financial reporting, and intercompany reconciliations. EIGE also may share its experience and lessons learned from the transition from ABAC to SUMMA and exchanges best practices with other agencies.
