The rule in plain words
Prudent valuation: core approach - Pre and post diversification (PRUVAL 2): a conditional check. The Bank's own words and formula below set it out in full.
The headline gives only the template and the kind of check, because the rule is too long to say in a headline. The plain words above say all of it.
What to do if your return fails it
- 01Open the tables below and find the cells the rule reads.
- 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.
- 03It runs only when your filing indicators mark C32.02.01 as reported.
- 04This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it.
