Prudent valuation: model risk AVA (PRUVAL 3): "of which: using expert based approach" must not be more than "Model risk AVA" (C32.03.01.01, Bank of England check v6360_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.

Check your PRA001 returnWhat to do if it fails

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.

What to do if your return fails it
