Luxembourg Commissariat aux Assurances (CAA) published Circular Letter 26/8 amending Circular Letter 22/10 on annual reporting by reinsurance undertakings. The changes are framed as clarifications rather than a redesign of the reporting files, and they tighten the rules on which financial year the annual return must cover and which reference date applies to information in the information sheet. For undertakings that do not close their financial year on 31 December, the CAA return must now cover the last financial year closed before or on 30 April of the current year, replacing the prior reference to the last year closed before 31 December of the previous calendar year. The information sheet must be completed with information applicable on the date the return is submitted, rather than the situation after the general meeting approving the annual accounts. Further clarifications address how to allocate premiums in the geographic origin tables (by the head office country of the cedant for accepted gross premiums and of the reinsurer for retroceded premiums), that staff numbers should be reported in full-time equivalents at year-end, and that totals in the general expenses table may not reconcile to the administration expenses figure in the profit and loss account due to different allocation bases. The circular also codifies the existence of three different reporting files (for small and medium-sized reinsurers, large commercial reinsurers with branches, and branches of reinsurers) and updates the list of supporting documents, including replacing a reference to a separate Solvency II report with a “separate complementary report” by the statutory auditor.

Luxembourg Commissariat aux Assurances amends annual reinsurance reporting guidance and sets a 30 April cut-off for non-calendar year ends
The Luxembourg Commissariat aux Assurances has issued Circular Letter 26/8 amending Circular Letter 22/10 on annual reporting by reinsurance undertakings, clarifying rather than redesigning requirements. Key changes tighten the definition of the financial year and reference date for returns and information sheets, refine instructions on geographic allocation of premiums, staff number reporting and expense reconciliations, and codify three distinct reporting files for different reinsurer types. The circular also updates the list of supporting documents, replacing the Solvency II report reference with a separate complementary report by the statutory auditor.
