(49)Not all assets within an undertaking are unrestricted. In some Member States, specific products result in ring-fenced fund structures which give one class of policy holders greater rights to assets within their own fund. Although those assets are included in computing the excess of assets over liabilities for own-fund purposes they cannot in fact be made available to meet the risks outside the ring-fenced fund. To be consistent with the economic approach, the assessment of own funds needs to be adjusted to reflect the different nature of assets, which form part of a ring-fenced arrangement. Similarly, the Solvency Capital Requirement calculation should reflect the reduction in pooling or diversification related to those ring-fenced funds.
