The European Insurance and Occupational Pensions Authority (EIOPA) has published technical specifications for Small and Non-Complex Undertakings (SNCUs) and Small and Non-Complex Groups (SNCGs), aimed at helping insurers and supervisors identify which entities qualify for the new simplified proportionality framework introduced by the Solvency II review and calculate the relevant risk indicators. The specifications set out how the limited set of quantitative and qualitative criteria should be applied, including the requirement that they be met consistently for two consecutive financial years. They also clarify which data points in the relevant Quantitative Reporting Templates should be used to determine SNCU/SNCG status and address specific scenarios where additional clarification may be needed, with the stated objective of supporting convergent implementation and supervisory practices across Member States. The document is intended to support implementation from the date of entry into application of the amended Solvency II Directive.
