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

Items "Non proportional reinsurer’s share - loss" and "Proportional reinsurer’s share - loss" must be reported

This is a blocking check. A return that fails it is normally rejected, so fix it before you submit. It runs only when your filing indicators mark S.27.02 as reported.

The cells it reads

Catastrophe data - loss data: reinsurance loss data - reporting for gross direct business (S.27.02.01.02)

Columns

  • C0080Non proportional reinsurer’s share - loss
  • C0090Proportional reinsurer’s share - loss

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.
