Prudent valuation: core approach - AVAs assessed to have zero value (PRUVAL 2): a value must not be negative (C32.02.01.02, Bank of England check v6572_s)

A blocking check on the prudent valuation: core approach - AVAs assessed to have zero value (PRUVAL 2) template (C32.02.01.02), 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: core approach - AVAs assessed to have zero value (PRUVAL 2) (C32.02.01.02): every value in "Of which: assessed to have zero value under article 9(2)" (row 0070) and "Of which: assessed to have zero value under article 10(2)&10(3)" (row 0080) in "Fair-value assets" (column 0130) and "Fair-value liabilities" (column 0140) must be zero or more.

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

  1. 01Open the table below and find the cells the rule reads.
  2. 02Look for a value below zero in these cells, such as an amount entered as a negative number.
  3. 03It runs only when your filing indicators mark C32.02.01 as reported.
  4. 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
