Insurance and reinsurance undertakings shall accompany any application for approval of an internal model with documentation demonstrating that the model meets the requirements set out in Articles R. 352-18 to R. 352-23.
Insurance and reinsurance undertakings may use partial internal models to calculate one or more of the following:
a) One or more of the risk modules or sub-modules of the Basic Solvency Capital Requirement referred to in Articles R. 352-5 and R. 352-6 ;
b) The capital requirement for operational risk defined in Article R. 352-8 ;
c) The adjustment provided for in Article R. 352-9.
Partial modelling may also be applied to the entire business of the insurance and reinsurance undertaking concerned, or only to one or more of its major business units.
Where the application for approval concerns a partial internal model, the requirements set out in Articles R. 352-18 to R. 352-23 are adapted to take account of the limited scope of the model.
Partial internal models are included in the calculation of the Solvency Capital Requirement in accordance with Article 239 of Commission Delegated Regulation (EU) 2015/35 of 10 October 2014.
