Article 233
Method 2 (Alternative method): Deduction and aggregation method
The group solvency of the participating insurance or reinsurance undertaking shall be the difference between the following:
the aggregated group eligible own funds, as provided for in paragraph 2;
the value in the participating insurance or reinsurance undertaking of the related insurance or reinsurance undertakings and the aggregated group Solvency Capital Requirement, as provided for in paragraph 3.
The aggregated group eligible own funds are the sum of the following:
the own funds eligible for the Solvency Capital Requirement of the participating insurance or reinsurance undertaking;
the proportional share of the participating insurance or reinsurance undertaking in the own funds eligible for the Solvency Capital Requirement of the related insurance or reinsurance undertakings.
The aggregated group Solvency Capital Requirement is the sum of the following:
the Solvency Capital Requirement of the participating insurance or reinsurance undertaking;
the proportional share of the Solvency Capital Requirement of the related insurance or reinsurance undertakings.
In determining whether the aggregated group Solvency Capital Requirement, calculated as set out in paragraph 3, appropriately reflects the risk profile of the group, the supervisory authorities concerned shall pay particular attention to any specific risks existing at group level which would not be sufficiently covered, because they are difficult to quantify.
Where the risk profile of the group deviates significantly from the assumptions underlying the aggregated group Solvency Capital Requirement, a capital add-on to the aggregated group Solvency Capital Requirement may be imposed.
Article 37(1) to (5), together with the delegated acts and implementing technical standards taken in accordance with Article 37(6), (7) and (8), shall apply mutatis mutandis.
