Own funds and list of items on own funds: a total must equal the sum of its parts (IR.23.01, IR.23.04, Bank of England rule IR_bv0855)

A blocking check on the own funds (IR.23.01) and list of items on own funds (IR.23.04) templates, in the annual solo (ARS) return.

The rule in plain words

The value of "Preference share" reported in template Own funds (IR.23.01.01.01) should be equal to the sum of the values reported in template Preference share (IR.23.04.01.02)

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 tables 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  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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 IR.23.01 and IR.23.04 as reported.
  6. 06This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

The Bank’s own words and formula

In the Bank of England’s list of validations, word for word:

The value of "Preference share" reported in template IR.23.01.01.01 - Own funds should be equal to the sum of the values reported in template IR.23.04.01.02 - Preference share.
Show the formulaShow

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

sum({t: IR.23.04.01.02, c: C0200}) = {t: IR.23.01.01.01, r: R0090, c: C0010, z: Z0001}

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.
