A partial internal model shall be approved by the Autorité de contrôle prudentiel et de résolution only where it meets the requirements set out in Article R. 352-13 and the following conditions:
a) Its limited scope is duly justified by the undertaking concerned;
b) The resulting Solvency Capital Requirement better reflects the risk profile of the undertaking concerned and, in particular, meets the requirements set out in Articles L. 352-1, R. 352-2 and R. 352-3;
c) Its design complies with the requirements set out in Articles L. 352-1, R. 352-2 and R. 352-3, so as to allow its full integration into the standard formula for calculating the Solvency Capital Requirement.
When assessing a request to use a partial internal model covering only certain sub-modules of a given risk module or only certain business units of the insurance or reinsurance undertaking with respect to a given risk module, or both in part, the Autorité de contrôle prudentiel et de résolution may require that undertaking to submit a realistic transition plan to extend the scope of its model.
This transition plan shall set out how the undertaking intends to extend the scope of its model to other sub-modules or business units, with a view to ensuring that the model covers a predominant part of its operations with respect to the given risk module.
