Non-life technical provisions: a total must equal the sum of its parts (S.17.01, EIOPA rule BV38)

A blocking check on the non-life technical provisions template (S.17.01), 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.

Check your file for this ruleWhat to do if it fails

The rule in plain words

The item "Technical provisions calculated as a whole" reported in Non-Life Technical Provisions (S.17.01) must be equal to the sum of "Direct business" and "Accepted proportional reinsurance business"

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. 02Add up the parts in your return and compare the result with the total.
  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.
  4. 04EIOPA allows a small rounding difference, worked out from the decimals each value is reported with.
  5. 05It runs only when your filing indicators mark S.17.01 as reported.
  6. 06This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

What the rule then expects

Technical provisions calculated as a whole must then be 2,000.

2,000Passes
2,100Fails

A file that reports 2,000 passes. One that reports 2,100 fails, by 100.

The numbers are illustrative, reported to the unit, so the rounding tolerance does not change the result.

Which returns it applies to

Line4 Check runs it on annual solo (ARS) and annual branch (ARB) returns on EIOPA taxonomy 2.10.0. EIOPA applies it to annual branch (ARB), annual solo (ARS), annual ECB solo (AES) and annual ECB branch (AEB) returns, as a blocking check.

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

{t: S.17.01.01.01, r: R0010} = {t: S.17.01.01.01, r: R0020} + {t: S.17.01.01.01, r: R0030}

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.
