Item “Underlying asset category” in Collective investment undertakings - look-through approach must be reported (S.06.03, EIOPA rule BV1135)

A blocking check on the collective investment undertakings - look-through approach template (S.06.03), in the quarterly solo (QRS), quarterly group (QRG) and quarterly branch (QRB) returns.

It applies to 2.8.2 returns too, the release for the 2026 returns, and Line4 Check runs it there as well.

The rule in plain words

Item “Underlying asset category” in Collective investment undertakings - look-through approach (S.06.03) must be reported

EIOPA writes it out as separate checks, one for each table or return it covers. Line4 Check runs two of them (BV1135-1 and BV1135-2), and a failure names the one that failed.

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.06.03 as reported.
  4. 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
