Solvency II replaces Solvency I as the new regulatory regime for insurance supervision in Europe. It aims to achieve consistency across Europe through market consistent balance sheets, risk-based capital requirements, own risk and solvency assessments, and senior management accountability. Solvency II has three pillars that define capital requirements, governance/risk management standards, and disclosure/transparency rules. It requires insurance companies to hold sufficient capital to ensure obligations can be met over 12 months with 99.5% probability under Pillar 1.
