(140)Directive 2009/138/EC requires participating insurance and reinsurance undertakings or insurance holding companies or mixed financial holding companies to disclose publicly information on the solvency and financial condition of the group. That Directive also allows them to provide a single solvency and financial condition report comprising both that group information and the solvency and financial condition information required in relation to any of their subsidiaries. That regime aims to ensure that interested stakeholders are properly informed about the solvency and financial condition of insurance and reinsurance groups, while at the same time reducing to the extent appropriate the related burden for such groups. In this context, it is necessary to harmonise the requirements applicable to public disclosure by insurance and reinsurance groups, regardless of whether such groups make use of the option to provide a single solvency and financial condition report.
