IGT - equity-type transactions, debt and asset transfer and 2 other templates: a conditional check (IR.36.01, IR.36.02, IR.36.04, Bank of England rule IR_bv1705)

A blocking check on the IGT - equity-type transactions, debt and asset transfer (IR.36.01), IGT - derivatives (IR.36.02) and IGT - cost sharing, contingent liabilities, off BS and other items (IR.36.04) templates, in the quarterly solo (QRS), quarterly group (QRG), annual solo (ARS), annual group (ARG) and annual third-country branch (ARB) returns.

Check your file for this ruleWhat to do if it fails

The rule in plain words

The item "Identification code and type of code for issuer / borrower" (IR.36.01.01.01 C0060, not a template of this return) is not in a valid format: it should be LEI/ followed by 18 capital letters or digits, then two digits (a valid LEI), SC/ followed by a code, or left empty

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