If, after having received the necessary approval from the Autorité de contrôle prudentiel et de résolution for the use of an internal model, an insurance or reinsurance undertaking ceases to comply with the requirements set out in Articles R. 352-18 to R. 352-23, it shall without delay submit to the Autorité de contrôle prudentiel et de résolution a plan for returning to compliance with those requirements within a reasonable period of time or demonstrate without delay that the effect of non-compliance is negligible.
Where the insurance or reinsurance undertaking fails to implement the plan referred to in the previous paragraph, the Autorité de contrôle prudentiel et de résolution may require it to revert to the standard formula for calculating its Solvency Capital Requirement, in accordance with Articles R. 352-4 to R. 352-11.
