Catastrophe data - exposure and premium data: a conditional check (S.27.03, EIOPA rule BV2582)

A warning on the catastrophe data - exposure and premium data template (S.27.03), in the annual solo (ARS) return.

It is new in taxonomy 2.10.0, for returns from the first quarter of 2027. 2.8.2 returns do not have it.

Check your file for this ruleWhat to do if it fails

The rule in plain words

If Gross earned premiums for direct business - all asset type (C0180) and Gross expenses incurred for direct business - all asset type (C0190) are reported, so should be Gross written premium for direct business - all asset type (C0170)

The headline gives only the template and the kind of check, because the rule is too long to say in a headline. The plain words above say all of it.

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.27.03 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.

The cells it reads

Catastrophe data - exposure and premium data: insurance premium and expenses - reporting for gross direct business (S.27.03.01.02)

Columns

  • C0170Gross written premium for direct business - all asset type
  • C0180Gross earned premiums for direct business - all asset type
  • C0190Gross expenses incurred for direct business - all asset type

Which returns it applies to

Line4 Check runs it on annual solo (ARS) return on EIOPA taxonomy 2.10.0. EIOPA applies it to annual ECB solo (AES) and annual solo (ARS) returns, as a warning.

if not(isnull({t: S.27.03.01.02, c: C0180})) and not(isnull({t: S.27.03.01.02, c: C0190})) then not(isnull({t: S.27.03.01.02, c: C0170})) else true()
