The rule in plain words
PPU materiality threshold in aggregate
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): "Percentage subject to permanent partial use permission (immateriality in aggregate)" in column "Percentage subject to permanent partial use permission (immateriality in aggregate) (%)" (row 0270, column 0180) must not be more than 0.05.
What to do if your return fails it
- 01Open the table below and find the cells the rule reads.
- 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.
- 03It runs only when your filing indicators mark OF08.07.01 as reported.
- 04This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it.
