Part 1: Assets: "Financial assets at Amortised Cost" must equal the sum of "Debt securities" and "Loans and advances" (SR01.01.03.01, Bank of England check boe_v5020_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 Amortised Cost" (row 0181) must equal the sum of "Debt securities" (row 0182) and "Loans and advances" (row 0183).

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  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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

  • R0181Financial assets at Amortised Cost
  • R0182Debt securities
  • R0183Loans and advances

Column

A worked example

With simple numbers.

Illustrative values
Debt securities1,200
Loans and advances800
Together2,000
What the rule then expects

Financial assets at Amortised Cost 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 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_v5020_m: T1: SR01.01.03.01; columns: {SR01.01.03.01, c0010}; Expression: {SR01.01.03.01, r0181} = {SR01.01.03.01, r0182} + {SR01.01.03.01, r0183}
Show the formulaShow

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

{t: SR01.01.03.01, r: 0181} = {t: SR01.01.03.01, r: 0182} + {t: SR01.01.03.01, r: 0183}

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

scope({t: SR01.01.03.01, c: 0010, seq: False, f: banking, fv: structural_reform})

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.
