(21)Supervisory authorities should be entitled to receive from each supervised insurance and reinsurance undertaking and their groups, at least every three years, a regular narrative report with information on the business and performance, system of governance, risk profile, capital management and other relevant information for solvency purposes. In order to simplify that reporting requirement for insurance and reinsurance groups, it should be possible, subject to certain conditions, to submit the information of the regular supervisory report relating to the group and its subsidiaries in an aggregated way for the whole group.
