"Total equity and total liabilities" must equal "Total assets" in Balance Sheet: Forecast data [Assets] (FF01.03.01.01, FF01.01.01.01, Bank of England check boe_v0783_m_1)

A blocking check on the balance Sheet: Forecast data [Equity] (FF01.03.01.01) and balance Sheet: Forecast data [Assets] (FF01.01.01.01) templates, in the PRA 104, 105, 106, 107 IFRS based balance sheet and profit & loss forecasts (PRA_IFRS) return.

Line4 Check runs it on the PRA 104, 105, 106, 107 IFRS based balance sheet and profit & loss forecasts (PRA_IFRS) return, proven on test files, check by check: the same outcome on all seven test files of that return.

Check your file for this ruleWhat to do if it fails

The rule in plain words

In each of "Forecast - end current year" (column 0010) and "Forecast - end next year" (column 0020) of Balance Sheet: Forecast data [Equity] (FF01.03.01.01): "Total equity and total liabilities" (row 0310) must equal "Total assets" (row 0380) in Balance Sheet: Forecast data [Assets] (FF01.01.01.01).

What to do if your return fails it

  1. 01Open the tables 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 FF01.01.01 and FF01.03.01 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

  • R0380Total assets

Columns

  • C0010Forecast - end current year
  • C0020Forecast - end next year

Row

  • R0310Total equity and total liabilities

Columns

  • C0010Forecast - end current year
  • C0020Forecast - end next year

A worked example

With simple numbers.

Illustrative values
Total assets, Forecast - end current year1,200
What the rule then expects

Total equity and total liabilities, Forecast - end current year 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

Line4 Check runs it on the PRA 104, 105, 106, 107 IFRS based balance sheet and profit & loss forecasts (PRA_IFRS) return on Bank of England banking taxonomy 4.1.1. The Bank of England applies it to PRA 104, 105, 106, 107 IFRS based balance sheet and profit & loss forecasts (PRA_IFRS) 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:

boe_v0783_m_1: [FF 01.03.01 (C0010-0020)] {FF 01.03.01, r0310} = {FF 01.01.01, r0380}
Show the formulaShow

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

{t: FF01.03.01.01, r: 0310} = {t: FF01.01.01.01, r: 0380}

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

scope({t: FF01.03.01.01, c: 0010; 0020, seq: False, f: banking, fv: financialstatements}, {t: FF01.01.01.01, c: 0010; 0020, seq: False, f: banking, fv: financialstatements})

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.
