(40)The existing Community legal framework for insurance should be adapted in order to take account of the new supervisory regime for reinsurance undertakings laid down by this Directive and in order to ensure a consistent regulatory framework for the whole insurance sector. In particular, the existing provisions which permit ‘indirect supervision’ of reinsurance undertakings by the authorities competent for the supervision of direct insurance undertakings should be adapted. Furthermore, it is necessary to abolish the current provisions enabling Member States to require pledging of assets covering the technical provisions of an insurance undertaking, whatever form this requirement might take, when the insurer is reinsured by a reinsurance undertaking authorised pursuant to this Directive or by an insurance undertaking. Finally, provision should be made for the solvency margin required for insurance undertakings conducting reinsurance activities, when such activities represent a significant part of their business, to be subject to the solvency rules provided for reinsurance undertakings in this Directive. Directives 73/239/EEC, 92/49/EEC and 2002/83/EC should therefore be amended accordingly.
