Intragroup financial reporting (detailed breakdown) Part 2: Fair value hierarchy: financial instruments at amortised cost: a total must equal the sum of its parts (SR41.01.04.01, Bank of England check boe_v1095_m)

A blocking check on the intragroup financial reporting (detailed breakdown) Part 2: Fair value hierarchy: financial instruments at amortised cost template (SR41.01.04.01), 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.

The rule in plain words

In each of "Fair value" (column 0010), "Level 1" (column 0020), "Level 2" (column 0030) and "Level 3" (column 0040) of Intragroup financial reporting (detailed breakdown) Part 2: Fair value hierarchy: financial instruments at amortised cost (SR41.01.04.01): "Financial liabilities measured at amortised cost" (row 0070) must equal the sum of "Deposits" (row 0080), "Debt securities issued" (row 0090) and "Other financial liabilities" (row 0100).

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  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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 SR41.01.04 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

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_v1095_m: T1: Sr041.01.04.01; columns: {Sr041.01.04.01, c0010-0040}; Expression: {Sr041.01.04.01, r0070} = sum({Sr041.01.04.01, r0080-0100})
Show the formulaShow

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

{t: SR41.01.04.01, r: 0070} = sum({t: SR41.01.04.01, r: 0080; 0090; 0100})

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

scope({t: SR41.01.04.01, c: 0010; 0020; 0030; 0040, seq: False, f: banking, fv: structural_reform})
