1. When calculating a capital add-on in relation to an insurance undertaking to which Article 73(2) or (5) of Directive 2009/138/EC applies, supervisory authorities shall calculate a notional life capital add-on and a notional non-life capital add-on.
2. Where the causes of the relevant deviations can be objectively apportioned between the life insurance activity and the non-life insurance activity, supervisory authorities shall calculate the notional life capital add-on and the notional non-life capital add-on according to the same apportionment.
3. Where an apportionment in accordance with paragraph 2 is not possible, supervisory authorities shall calculate the notional life capital add-on and notional non-life capital add-on in the same way as the apportionment between the notional life Minimum Capital Requirement and the notional non-life Minimum Capital Requirement as referred to in Article 74(2) of Directive 2009/138/EC.
