Premiums, claims and expenses by line of business: values must agree (S.05.01, EIOPA rule BV210)

A blocking check 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

The item "Premiums written - Net" reported in Premiums, claims and expenses by line of business (S.05.01) must be equal to the sum of "Premiums written - Direct business" with "Premiums written - proportional reinsurance accepted" and "Premiums written - non-proportional reinsurance accepted" minus "Premiums written - Reinsurers' share"

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.05.01 as reported.

EIOPA's formula. Cells are written as {t: table, r: row, c: column}.

{t: S.05.01.02.01, r: R0200, z: Z0001} = {t: S.05.01.02.01, r: R0110, z: Z0001} + {t: S.05.01.02.01, r: R0120, z: Z0001} + {t: S.05.01.02.01, r: R0130, z: Z0001} - {t: S.05.01.02.01, r: R0140, z: Z0001}

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.
