Premiums, claims and expenses by line of business: a conditional check (S.05.01, EIOPA rule BV2583)

A warning on the premiums, claims and expenses by line of business template (S.05.01), in the annual solo (ARS), annual group (ARG) and annual branch (ARB) returns.

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

It is expected that administrative expenses will be recognised, provided that Expenses incurred are also provided

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.05.01 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.

The cells it reads

Premiums, claims and expenses by line of business: non-life (direct business/accepted proportional reinsurance and accepted non-proportional reinsurance) (S.05.01.01.01)

Which returns it applies to

EIOPA’s own words and formula

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.
