Collective investment undertakings - look-through approach: a check on its values (IR.06.03, Bank of England rule IR_bv0749_01)

A warning on the collective investment undertakings - look-through approach template (IR.06.03), in the quarterly solo (QRS), quarterly group (QRG), annual solo (ARS) and annual group (ARG) returns.

The rule in plain words

The item "Country of issue" in Collective investment undertakings - look-through approach (IR.06.03.01.01) should be reported for assets different from "Underlying asset category" 7, 8 and 9

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.

This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it. It runs only when your filing indicators mark IR.06.03 as reported.
