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.

Check your file for this ruleWhat to do if it fails

The rule in plain words

Check that reported values are positive numbers or zero

In Credit and counterparty credit risks and free deliveries: standardised approach to capital requirements (CR SA) (OF07.00.01.01): every value in the cells it covers must be zero or more.

What to do if your return fails it

  1. 01Open the tables below and find the cells the rule reads.
  2. 02Look for a value below zero in these cells, such as an amount entered as a negative number.
  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.
