Retrocession's share: loss - All asset type column must be reported as positive amount (S.27.02, EIOPA rule BV2569)

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

Retrocession's share: loss - All asset type column must be reported as positive amount

What to do if your return fails it

  1. 01Open the table below and find the cells the rule reads.
  2. 02Look for a value below zero in these cells, such as an amount entered as a negative number.
  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)
