Non-life technical provisions and non-life technical provisions - by country: a total must equal the sum of its parts (S.17.01, S.17.03, EIOPA rule BV2013)

A warning on the non-life technical provisions (S.17.01) and non-life technical provisions - by country (S.17.03) templates, 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

The sum of gross TP as a whole and gross best estimate for all countries reported in template S.17.03 is equal to the total for that LoB reported in template S.17.01 (accepted non-proportional reinsurance business, TP as a whole + gross BE)

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 tables 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  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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 and S.17.03 as reported.
  6. 06This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it.

EIOPA’s own words and formula

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

sum({t: S.17.01.01.01, r: R0040; R0090; R0190, c: C0170}) = sum({t: S.17.03.01.01, r: R0070; R0080; R0090, c: C0170}) + sum({t: S.17.03.01.03, r: R0110, c: C0170, 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.
