On 26 January 2016, EIOPA published an opinion on the application of a combination of methods (i.e. those under Articles 320 and 233 of the Solvency II Directive) to the group solvency calculation. Key points highlighted include that, where a combination of methods is proposed, (a) the group supervisor needs to consider the criteria specified in Commission Delegated Regulation (EU/2015/35) and (b) there may be unintended consequences of using a combination of calculation methods in certain circumstances.
