Catastrophe data - exposure and premium data: a value must not be less than another (S.27.03, EIOPA rule BV2581)

A blocking check 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.

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 tables below and find the cells the rule reads.
  2. 02Compare the values in your return. If the first is smaller than it may be, one of them is wrong: check both before you change either.
  3. 03It runs only when your filing indicators mark S.27.03 as reported.
  4. 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
