Catastrophe data - loss data: a value must not be less than another (S.27.02, EIOPA rule BV2571)

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.

Check your file for this ruleWhat to do if it fails

The rule in plain words

Sum of Non Proportional reinsurance accepted: loss - all asset and Proportional reinsurance accepted: loss - all asset, must greater or equal to Retrocession's share: loss - all asset type column

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. 02Compare the values in your return. If the first is smaller than it may be, one of them is wrong: check both before you change either.
  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.
