"Other debt securities issued" must equal the sum of "Convertible compound financial instruments" and "Non-convertible" (SR08.01.04.01, Bank of England check boe_v1948_m)

A blocking check on the intragroup financial reporting (detailed breakdown) Breakdown of financial liabilities template (SR08.01.04.01), in the intragroup financial reporting (core and detailed breakdowns) (RFB004) return.

Line4 Check runs it on the intragroup financial reporting (core and detailed breakdowns) (RFB004) 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 each of "Held for trading" (column 0010), "Designated at fair value through profit or loss" (column 0020) and "Amortised cost" (column 0030) of Intragroup financial reporting (detailed breakdown) Breakdown of financial liabilities (SR08.01.04.01): "Other debt securities issued" (row 0410) must equal the sum of "Convertible compound financial instruments" (row 0420) and "Non-convertible" (row 0430).

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  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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 SR08.01.04 as reported.
  6. 06This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

A worked example

With simple numbers.

Illustrative values
Convertible compound financial instruments1,200
Non-convertible800
Together2,000
What the rule then expects

Other debt securities issued 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.

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_v1948_m: T1: SR08.01.04.01; columns: {SR08.01.04.01, c0010;0020;0030}; Expression: {SR08.01.04.01, r0410} = {SR08.01.04.01, r0420} + {SR08.01.04.01, r0430}
Show the formulaShow

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

{t: SR08.01.04.01, r: 0410} = {t: SR08.01.04.01, r: 0420} + {t: SR08.01.04.01, r: 0430}

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

scope({t: SR08.01.04.01, c: 0010; 0020; 0030, seq: False, f: banking, fv: structural_reform})
