The rule in plain words

The "External rating" should not be provided whether no ECAI has been nominated and a simplification is being used to calculate the SCR

What to do if your return fails it

  1. 01Open the table below and find the cells the rule reads.
  2. 02The check applies only when its first part holds in your return. When it does, the second part must hold too: fix the second part, or correct the first.
  3. 03It runs only when your filing indicators mark IR.06.02 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.
