The CDFs reported in S.26.13 should rise monotonically (S.01.02, S.26.13, EIOPA rule BV2525)

A warning on the basic information (S.01.02) and internal model - non-life and health NSLT underwriting risk (S.26.13) templates, in the annual solo (ARS) return.

It is new in taxonomy 2.10.0, for returns from the first quarter of 2027. 2.8.2 returns do not have it.

The rule in plain words

The CDFs reported in S.26.13 should rise monotonically

What to do if your return fails it

  1. 01Open the tables below and find the cells the rule reads.
  2. 02The check applies only when its first part holds in your return. When it does, the second part must hold too: fix the second part, or correct the first.
  3. 03It runs only when your filing indicators mark S.01.02 and S.26.13 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.

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

if {t: S.01.02.01.01, r: R0130, c: C0010} != [s2c_AP:x3] then {t: S.26.13.01.11, r: R1740, z: Z0001} <= {t: S.26.13.01.11, r: R1750, z: Z0001} else true()

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.
