"Total fair-valued liabilities" must equal "Derivatives - hedge accounting" (C32.01.01.01, Bank of England check v6326_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.

Check your file for this ruleWhat to do if it fails

The rule in plain words

In column "Hedge accounting" (0040) of Prudent valuation: fair-valued assets and liabilities (PRUVAL 1) (C32.01.01.01): "Total fair-valued liabilities" (row 0150) must equal "Derivatives - hedge accounting" (row 0190).

What to do if your return fails it

  1. 01Open the table below and find the cells the rule reads.
  2. 02The two values must be the same. Find which of the two is right, and correct the other one.
  3. 03The Bank of England allows a small rounding difference, worked out from the decimals each value is reported with.
  4. 04It runs only when your filing indicators mark C32.01.01 as reported.
  5. 05This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

The cells it reads

Prudent valuation: fair-valued assets and liabilities (PRUVAL 1) (C32.01.01.01)

Rows

  • R0150Total fair-valued liabilities
  • R0190Derivatives - hedge accounting

Column

  • C0040Hedge accounting

A worked example

With simple numbers.

Illustrative values
Derivatives - hedge accounting1,200
What the rule then expects

Total fair-valued liabilities must then be 1,200.

1,200Passes
1,300Fails

A file that reports 1,200 passes. One that reports 1,300 fails, by 100.

The numbers are illustrative, reported to the unit, so the rounding tolerance does not change the result.

Which returns it applies to
