Columns "Non Proportional reinsurance accepted: loss - All asset" and "Proportional reinsurance accepted: loss - All asset" must be reported (S.27.02, EIOPA rule BV2570)

A blocking check on the catastrophe data - loss data template (S.27.02), 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

Columns "Non Proportional reinsurance accepted: loss - All asset" and "Proportional reinsurance accepted: loss - All asset" must be reported

What to do if your return fails it

  1. 01Open the table 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.27.02 as reported.
  4. 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

The cells it reads

Catastrophe data - loss data: reinsurance loss data - reporting for reinsurance business (S.27.02.01.03)

Columns

  • C0100Non proportional reinsurance accepted: loss - All asset
  • C0110Proportional reinsurance accepted: loss - All asset
  • C0120Retrocession's share: loss - All asset type

Which returns it applies to

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

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

if not(isnull({t: S.27.02.01.03, c: C0100})) or not(isnull({t: S.27.02.01.03, c: C0110})) or not(isnull({t: S.27.02.01.03, c: C0120})) then not(isnull({t: S.27.02.01.03, c: C0100})) and not(isnull({t: S.27.02.01.03, c: C0110})) 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.
