"Total fair-valued assets and liabilities" must equal the sum of "Total fair-valued assets" and "Total fair-valued liabilities" (C32.01.01.01, Bank of England check v6320_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 8 columns (listed below) of Prudent valuation: fair-valued assets and liabilities (PRUVAL 1) (C32.01.01.01): "Total fair-valued assets and liabilities" (row 0010) must equal the sum of "Total fair-valued assets" (row 0020) and "Total fair-valued liabilities" (row 0150).

What to do if your return fails it

  1. 01Open the table below and find the cells the rule reads.
  2. 02Add up the parts in your return and compare the result with the total.
  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.
  4. 04The Bank of England allows a small rounding difference, worked out from the decimals each value is reported with.
  5. 05It runs only when your filing indicators mark C32.01.01 as reported.
  6. 06This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

A worked example

With simple numbers.

Illustrative values
Total fair-valued assets1,200
Total fair-valued liabilities800
Together2,000
What the rule then expects

Total fair-valued assets and liabilities must then be 2,000.

2,000Passes
2,100Fails

A file that reports 2,000 passes. One that reports 2,100 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

Line4 Check runs it on the own funds (PRA001) return on Bank of England banking taxonomy 4.1.1. The Bank of England applies it to own funds (PRA001) returns, as a blocking check.

The Bank’s own words and formula

The plain words above spell out the Bank’s formula, with each cell named from its templates. In the Bank of England’s list of validations, word for word:

v6320_m: [C32.01.01.01 (c0010;0020;0030;0040;0050;0060;0080;0090)] {r0010} = {r0020} + {r0150}
Show the formulaShow

The Bank of England's formula. Cells are written as {t: table, r: row, c: column}.

{t: C32.01.01.01, r: 0010} = {t: C32.01.01.01, r: 0020} + {t: C32.01.01.01, r: 0150}

Where it applies, in the Bank's words (its scope):

scope({t: C32.01.01.01, c:0010;0020;0030;0040;0050;0060;0080;0090, f: banking, fv: banking_reporting})

Checks like this one, run at the point of submission, are the first step to real-time supervision. Line4 builds SupTech software for financial regulators that runs checks like these as each return arrives.
