The European Insurance and Occupational Pensions Authority (EIOPA) has published new Guidelines on diversity considerations that (re)insurance undertakings should take into account when selecting members of their administrative, management and supervisory bodies, alongside revised Guidelines on methods for determining market shares for supervisory reporting. The diversity Guidelines respond to amendments introduced via the Solvency II Review, including a requirement for (re)insurers to adopt policies promoting diversity within these bodies and to set quantitative objectives related to gender balance. The diversity Guidelines aim to support a more diverse composition of senior decision-makers based on educational and professional background, age, gender and geographical origin, both in recruitment and on an ongoing basis. They apply to all (re)insurance undertakings and groups and were developed to align with similar diversity guidelines for banks and financial market participants. The revised market share Guidelines update the existing reporting approach to reflect legal changes made through the Solvency II Review. Both sets of Guidelines will become applicable as of 30 January 2027.
