Consistency check for Corporates (Specialised Lending) Risk-weighted exposures under non-modelled approaches across OF02 and OF08.01 (OF02.00.01.01, OF08.01.01.01, Bank of England check boe_b2290)

A warning on the own funds requirements (CA2) (OF02.00.01.01) and credit and counterparty credit risks and free deliveries: IRB approach to capital requirements (CR IRB 1) (OF08.01.01.01) templates, in the own funds (PRA001) return.

Line4 Check runs it on the own funds (PRA001) return, proven on test files, check by check: the same outcome on all three test files of that return.

The rule in plain words

Consistency check for Corporates (Specialised Lending) Risk-weighted exposures under non-modelled approaches across OF02 and OF08.01

In Own funds requirements (CA2) (OF02.00.01.01): "Corporates - Specialised lending exposures" in column "Standardised approaches only (Output Floor)" (row 0290, column 0020) must not be more than "Total exposures" in column "Non-modelled approaches risk-weighted exposure value" (row 0010, column 0276) on sheet "Corporates - Specialised Lending (FIRB approach or slotting approach)" (sheet 0010) in Credit and counterparty credit risks and free deliveries: IRB approach to capital requirements (CR IRB 1) (OF08.01.01.01).

What to do if your return fails it

  1. 01Open the tables below and find the cells the rule reads.
  2. 02Compare the values in your return. If the first is bigger than it may be, one of them is wrong: check both before you change either.
  3. 03It runs only when your filing indicators mark OF02.00.01 and OF08.01.01 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.
