Part 1: Assets: a total must equal the sum of its parts (SR01.01.03.01, Bank of England check boe_v0766_m)

A blocking check on the part 1: Assets template (SR01.01.03.01), in the intragroup financial reporting (core) (RFB003) return.

Line4 Check runs it on the intragroup financial reporting (core) (RFB003) return, proven on test files, check by check: the same outcome on all eight test files of that return.

Check your file for this ruleWhat to do if it fails

The rule in plain words

In column "Carrying amount: Intragroup transactions" (column 0010) of Part 1: Assets (SR01.01.03.01): "Financial assets at fair value through other comprehensive income" (row 0141) must equal the sum of "Equity instruments" (row 0142), "Debt securities" (row 0143) and "Loans and advances" (row 0144).

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 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  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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 SR01.01.03 as reported.
  6. 06This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

The cells it reads

A worked example

With simple numbers.

Illustrative values
Equity instruments1,200
Debt securities800
Loans and advances450
Together2,450
What the rule then expects

Financial assets at fair value through other comprehensive income must then be 2,450.

2,450Passes
2,550Fails

A file that reports 2,450 passes. One that reports 2,550 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 intragroup financial reporting (core) (RFB003) return on Bank of England banking taxonomy 4.1.1. The Bank of England applies it to intragroup financial reporting (core) (RFB003) 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_v0766_m: T1: SR01.01.03.01; columns: {SR01.01.03.01, c0010}; Expression: {SR01.01.03.01, r0141} = {SR01.01.03.01, r0142} + {SR01.01.03.01, r0143} + {SR01.01.03.01, r0144}

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

{t: SR01.01.03.01, r: 0141} = {t: SR01.01.03.01, r: 0142} + {t: SR01.01.03.01, r: 0143} + {t: SR01.01.03.01, r: 0144}

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

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.
