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 rule in plain words

For the reported premiums there must be exposure reported for corresponding peril

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.27.03 as reported.
  4. 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
