Member States shall require participating insurance and reinsurance undertakings, insurance holding companies and mixed financial holding companies to submit to the group supervisor an annual regular supervisory report at group level; Article 35(5a) applies mutatis mutandis. Insurance and reinsurance undertakings must provide the information referred to in this Article on an annual or less frequent basis within 24 weeks of the end of the undertaking's financial year.

Subject to the group supervisor's agreement, a single regular supervisory report may combine group-level information and individually identifiable subsidiary information, which must not contain less detail than required by Article 35(5a). The group supervisor shall consult the college of supervisors before granting agreement and national supervisors' non-agreement must be duly justified. If approved, each undertaking submits the single report to its supervisory authority, which may supervise the part specific to its subsidiary, require additional information for material omissions, and the agreement may be withdrawn if the report is unsatisfactory. The supervisory authority must inform the college of supervisors of requests for amendment or clarification and the group supervisor shall transmit the same request to the undertaking. The Commission shall adopt delegated acts under Article 301 to further specify the information to be reported.
