The rule in plain words
In Prudent valuation: core approach - Pre and post diversification (PRUVAL 2) (C32.02.01.01): "Total category level pre-diversification" in column "Model risk" (row 0040, column 0050) must not be less than the sum of "Model risk AVA" (column 0050) in Prudent valuation: model risk AVA (PRUVAL 3) (C32.03.01.01).
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.
- 02Compare the values in your return. If the first is smaller than it may be, one of them is wrong: check both before you change either.
- 03This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
