List of assets and 3 other templates: the format of a code or text (IR.06.02, IR.08.01, IR.05.07 and others, Bank of England rule IR_bv1686)

A blocking check on the list of assets (IR.06.02), open derivatives (IR.08.01), business model analysis - financial guarantee insurers (IR.05.07) and assets held as collateral (IR.11.01) templates, in the quarterly solo (QRS), quarterly group (QRG), annual solo (ARS), annual group (ARG) and annual third-country branch (ARB) returns.

The rule in plain words

The item "CIC" (IR.06.02.01.02 C0290) is not in a valid format: it should be two capital letters, then one capital letter or digit, then one digit

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. 03This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
