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 [Assets] (FF01.01.01.01): "Total assets" (row 0380) must equal the sum of 14 cells (listed below).

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  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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 FF01.01.01 as reported.
  6. 06This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

boe_v0768_m_1: [FF 01.01.01 (C0010-0020)] {r0380} = {r0010} + {r0050} + {r0096} + {r0100} + {r0141} + {r0181} + {r0240} + {r0250} + {r0260} + {r0270} + {r0300} + {r0330} + {r0360} + {r0370}

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

{t: FF01.01.01.01, r: 0380} = {t: FF01.01.01.01, r: 0010} + {t: FF01.01.01.01, r: 0050} + {t: FF01.01.01.01, r: 0096} + {t: FF01.01.01.01, r: 0100} + {t: FF01.01.01.01, r: 0141} + {t: FF01.01.01.01, r: 0181} + {t: FF01.01.01.01, r: 0240} + {t: FF01.01.01.01, r: 0250} + {t: FF01.01.01.01, r: 0260} + {t: FF01.01.01.01, r: 0270} + {t: FF01.01.01.01, r: 0300} + {t: FF01.01.01.01, r: 0330} + {t: FF01.01.01.01, r: 0360} + {t: FF01.01.01.01, r: 0370}
