Content of the submission and 2 other templates: a conditional check (IR.01.01, IR.02.01, IR.06.02, Bank of England rule IR_bv1736)

A warning on the content of the submission (IR.01.01), balance sheet (IR.02.01) and list of assets (IR.06.02) templates, in the quarterly solo (QRS) return.

Check your file for this ruleWhat to do if it fails

The rule in plain words

If the assets with CIC '##4#' are higher than 30% of the investments and assets held for index-linked and unit-linked contracts, then Collective investment undertakings - look-through approach (IR.06.03) should be reported, unless the undertaking is exempted

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. 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. 03The Bank of England allows a small rounding difference, worked out from the decimals each value is reported with.
  4. 04It runs only when your filing indicators mark IR.01.01, IR.02.01 and IR.06.02 as reported.
  5. 05This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it.
