(75)Where the calculation of the capital requirement for a risk module or sub-module of the Basic Solvency Capital Requirement is based on the impact of bidirectional scenarios on basic own funds, as in interest rate risk, currency risk or lapse risk, the insurance or reinsurance undertaking should determine which scenario most negatively affects the basic own funds of the insurance or reinsurance undertaking as a whole. This determination should, where relevant, take into account the effects of profit participation and the distribution of future discretionary benefits at the level of the ring-fenced fund. The scenario determined in this way should be the relevant scenario to calculate the notional Solvency Capital Requirement for each ring-fenced fund.
