Prudent valuation: model risk AVA (PRUVAL 3): a check on its values (C32.03.01.01, Bank of England check v7784_m)

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

Line4 Check runs it on the own funds (PRA001) return, proven on test files, check by check: the same outcome on all three test files of that return.

The rule in plain words

In Prudent valuation: model risk AVA (PRUVAL 3) (C32.03.01.01): every value in "IPV coverage (output testing)" (column 0120) must be zero or more, and every value in "IPV coverage (output testing)" (column 0120) must not be more than 1.

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.

This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it. It runs only when your filing indicators mark C32.03.01 as reported.
