Development of the distribution of the claims incurred: values must agree (S.20.01, EIOPA rule BV54)

A blocking check on the development of the distribution of the claims incurred template (S.20.01), in the annual solo (ARS) and annual branch (ARB) 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

For "Claims reported during the year", the item "Total" reported in Development of the distribution of the claims incurred (S.20.01) must be equal to the sum of the "Total previous years" and "N"

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.20.01 as reported.

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

{t: S.20.01.01.01, r: R0180, z: Z0001} = {t: S.20.01.01.01, r: R0160, z: Z0001} + {t: S.20.01.01.01, r: R0170, 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.
