Collective investment undertakings - look-through approach: a value must not be negative (S.06.03, EIOPA rule BV797)

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

When an item is a liability, excluding derivatives, then it is classified as "L" and must be reported positive in template Collective investment undertakings - look-through approach (S.06.03)

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.

EIOPA writes it out as separate checks, one for each table or return it covers. Line4 Check runs two of them (BV797-1 and BV797-2), 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. 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.06.03 as reported.
  4. 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

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.
