(26)The starting point for the adequacy of the quantitative requirements in the insurance sector is the Solvency Capital Requirement. Supervisory authorities should therefore have the power to impose a capital add-on to the Solvency Capital Requirement only under exceptional circumstances, in the cases listed in this Directive, following the supervisory review process. The Solvency Capital Requirement standard formula is intended to reflect the risk profile of most insurance and reinsurance undertakings. However, there may be some cases where the standardised approach does not adequately reflect the very specific risk profile of an undertaking.
