The item "Country of residency" should be reported in Share of reinsurers [including Finite Reinsurance and SPV's] (S.31.01, EIOPA rule BV934)

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

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

The item "Country of residency" should be reported in Share of reinsurers (S.31.01) [including Finite Reinsurance and SPV's]

EIOPA writes it out as separate checks, one for each table or return it covers. Line4 Check runs two of them (BV934-1 and BV934-2), and a failure names the one that failed.

What to do if your return fails it

  1. 01Open the tables 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.

if (not(isNull({t: S.31.01.01.01, c: C0100, z: Z0001}))) then not(isNull({t: S.31.01.01.02, c: C0200})) else true()

BV934-1:

if (not(isNull({t: S.31.01.04.01, c: C0100, z: Z0001}))) then not(isNull({t: S.31.01.04.02, c: C0200})) else true()
