1 min readWarningBank of England taxonomy 2.2.0Updated 11 November 2026

List of assets: the format of a code or text (IR.06.02, Bank of England rule IR_bv0529_01)

A warning on the list of assets template (IR.06.02), in the quarterly solo (QRS) and annual solo (ARS) returns.

The rule in plain words

The item "Issuer sector" for NACE 2.0 and NACE 2.1 in List of assets (IR.06.02.01.02) should be reported for assets with CIC different from '##71', '##75', '##8#', '##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.

What to do if your return fails it

  1. 01Open the table 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 as reported.
  4. 04This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it.
