Catastrophe data - exposure and premium data: a check on its values (S.27.03, EIOPA rule BV2574)

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

Values provided in columns C0150 (Deductable) and C0160 (Loss limit) must be between 0 and 100 percent, provided as 0 - 1

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.

This is a blocking check. A return that fails it is normally rejected, so fix it before you submit. It runs only when your filing indicators mark S.27.03 as reported.

The cells it reads

Catastrophe data - exposure and premium data: insurance exposure (sum insured value) - reporting for gross direct business (S.27.03.01.01)

Columns

  • C0150Deductible
  • C0160Loss limit

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 solo (ARS) and annual ECB solo (AES) returns, as a blocking check.

Checks like this one, run at the point of submission, are the first step to real-time supervision. Line4 builds SupTech software for financial regulators that runs checks like these as each return arrives.
