List of assets and collective investment undertakings - look-through approach: the format of a code or text (IR.06.02, IR.06.03, Bank of England rule IR_bv0903_02)

A blocking check on the list of assets (IR.06.02) and collective investment undertakings - look-through approach (IR.06.03) templates, in the quarterly group (QRG) return.

The rule in plain words

There is at least one asset reported in Collective investment undertakings - look-through approach (IR.06.03) that according to List of assets (IR.06.02) doesn’t have a form of Collective Investment Undertaking

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.

What to do if your return fails it

  1. 01Open the tables below and find the cells the rule reads.
  2. 02Compare the code or text in your return with the format the rule sets out, character by character, including any prefix and any spaces.
  3. 03It runs only when your filing indicators mark IR.06.02 and IR.06.03 as reported.
  4. 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
