Credit and counterparty credit risks and free deliveries: standardised approach to capital requirements (CR SA): a cell must be left empty (OF07.00.01.01, OF09.01.01.01, Bank of England check boe_b0431)

A warning on the credit and counterparty credit risks and free deliveries: standardised approach to capital requirements (CR SA) (OF07.00.01.01) and geographical breakdown of exposures by residence of the obligor: SA exposures (OF CR GB 1) (OF09.01.01.01) 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

Defaulted exposures (row 0015) should be reported only for items associated with a particularly high risk (s0012), subordinated debt, equity and other own funds instrument (s0016) and CIUs (s0015). This data entry should be left blank in all the other sheets.

In Credit and counterparty credit risks and free deliveries: standardised approach to capital requirements (CR SA) (OF07.00.01.01): "of which: Defaulted exposures" (row 0015) in 22 columns (listed below) on 12 sheets must be 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. 02Remove the value from this cell where the rule applies. A 0 is a value too, so leave the cell out of the return altogether.
  3. 03It runs only when your filing indicators mark OF07.00.01 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.
