Items "Reinsurance recoverables: Total reinsurance recoverables" and "Legal name of reinsured undertaking" should always be provided (S.31.01, EIOPA rule BV1617)

A warning on the share of reinsurers (including finite reinsurance and SPV's) template (S.31.01), in the annual group (ARG) return.

It applies to 2.8.2 returns too, the release for the 2026 returns, and Line4 Check runs it there as well.

The rule in plain words

Items "Reinsurance recoverables: Total reinsurance recoverables" and "Legal name of reinsured undertaking" should always be provided

What to do if your return fails it

  1. 01Open the table below and find the cells the rule reads.
  2. 02The check applies only when its first part holds in your return. When it does, the second part must hold too: fix the second part, or correct the first.
  3. 03It runs only when your filing indicators mark S.31.01 as reported.
  4. 04This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it.
