Prudent valuation: fair-valued assets and liabilities (PRUVAL 1): values must agree (C32.01.01.01, Bank of England check v6331_m)

A blocking check on the prudent valuation: fair-valued assets and liabilities (PRUVAL 1) template (C32.01.01.01), 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 each of "Derivatives - hedge accounting" (row 0110) and "Derivatives - hedge accounting" (row 0190) of Prudent valuation: fair-valued assets and liabilities (PRUVAL 1) (C32.01.01.01): "Fair-valued assets and liabilities included in art. 4(1) threshold" (column 0080) must equal "Fair-valued assets and liabilities" (column 0010) minus "Hedge accounting" (column 0040) minus "Prudential filters" (column 0050) minus "Other" (column 0060).

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 blocking check. A return that fails it is normally rejected, so fix it before you submit. It runs only when your filing indicators mark C32.01.01 as reported.
