Premiums, claims and expenses by line of business: a value must not be negative (S.05.01, EIOPA rule BV1185)

A warning on the premiums, claims and expenses by line of business template (S.05.01), in the quarterly solo (QRS), quarterly group (QRG) and quarterly branch (QRB) returns.

It applies to 2.8.2 returns too, the release for the 2026 returns, and Line4 Check runs it there as well.

The rule in plain words

Value of premiums written and premiums earned should, in general, be positive or equal to zero, although there might be some exemptions

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. 02Look for a value below zero in these cells, such as an amount entered as a negative number.
  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.05.01.02.01)

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.
