Prudent valuation: model risk AVA (PRUVAL 3): "of which: aggregated using method 2" must not be more than "Model risk AVA" (C32.03.01.01, Bank of England check v6361_m)

A blocking check on the prudent valuation: model risk AVA (PRUVAL 3) template (C32.03.01.01), in the own funds (PRA001) return.

Line4 Check does not run it on the own funds (PRA001) return. Held back after a different result on a test file. It gave a different result on at least one of Line4’s test files: a different outcome, or a different number of times tested. It is held back while we settle which is right, and stays out until it is proven.

Line4 Check does not run this check yet, so the button checks your return against the Bank's other checks for it. The validation run when you submit includes this one.

The rule in plain words

In Prudent valuation: model risk AVA (PRUVAL 3) (C32.03.01.01): "of which: aggregated using method 2" (column 0070) must not be more than "Model risk AVA" (column 0050).

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. 03This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
