The European Insurance and Occupational Pensions Authority (EIOPA) has published its final guidelines on diversity in the selection of members of administrative, management or supervisory bodies (AMSBs) in insurance and reinsurance undertakings. These guidelines were developed following amendments to Article 41(1) of the Solvency II Directive, which require undertakings to adopt diversity policies and set quantitative gender balance objectives. Effective from 30 January 2027, the guidelines promote diversity in terms of educational and professional background, age, gender and geographical origin. They aim to enhance decision-making by fostering a range of perspectives and reducing groupthink, and are aligned with corresponding frameworks in the banking and financial sectors for consistency across the EU. Following a public consultation between December 2024 and February 2025, EIOPA incorporated stakeholder feedback, including the removal of a proposed requirement to report non-compliance with gender balance targets to reduce the reporting burden. Competent authorities must integrate the Guidelines into their supervisory frameworks and confirm compliance to EIOPA within two months of the translated versions’ publication.
