The rule in plain words

Change in exposure due to FCCM shall be less than or equal to zero

In Credit risk and free deliveries: IRB approach to capital requirements: specialised lending slotting approach (CR IRB 6) (OF08.06.01.01): every value in the cells it covers must be zero or less.

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 OF08.06.01 as reported.
  4. 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
