The rule in plain words

Permanent Partial Use (PPU) materiality of roll-out class threshold

In Credit risk and free deliveries: IRB approach to capital requirements: scope of use of IRB and SA approaches (CR IRB 7) (OF08.07.01.01): every value in the cells it covers must not be more than 0.05.

What to do if your return fails it

  1. 01Open the table 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 OF08.07.01 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.
