The rule in plain words
In Market risk: internal models (MKR IM) (C24.00.01.01): "Total positions" in column "Number of overshootings during previous 250 working days" (row 0010, column 0140) must not be more than 250.
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 C24.00.01 as reported.
- 04This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it.
