EIOPA has published its opinion on applying a combination of methods to the group solvency calculation under Solvency 2. Firms can make the calculation on the basis of consolidation, deduction and aggregation or a combination of the two methods. EIOPA recognises that combining methods may lead to unintended consequences and suggests safeguards to address prudential concerns and ensure no group is placed in an advantageous position. EIOPA also recommends that when using a combination of methods, the provisions of Solvency 2 relevant to each of the methods should apply so there are distinct tier limits for the specific parts of the group that use each method.
