1 min readWarningBank of England taxonomy 2.2.0Updated 11 November 2026

Basic information - RFF and matching adjustment portfolios and list of assets: a conditional check (IR.01.03, IR.06.02, Bank of England rule IR_bv0550_01)

A warning on the basic information - RFF and matching adjustment portfolios (IR.01.03) and list of assets (IR.06.02) templates, in the annual solo (ARS) return.

The rule in plain words

Each Matching portfolio number reported in IR.06.02 C0080 must be also reported in IR.01.03 C0040, with IR.01.03 RFF/MAP/Remaining part of a fund (C0060) = “Matching Adjustment Portfolios”

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. 03It runs only when your filing indicators mark IR.01.03 and 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.
