Intragroup financial reporting (detailed breakdown) Information on forborne exposures to other group entities: a total must equal the sum of its parts (SR19.00.04.02, Bank of England check boe_v3087_h)

A blocking check on the intragroup financial reporting (detailed breakdown) Information on forborne exposures to other group entities template (SR19.00.04.02), 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 8 rows (listed below) of Intragroup financial reporting (detailed breakdown) Information on forborne exposures to other group entities (SR19.00.04.02): "Accumulated impairment, accumulated negative changes in fair value due to credit risk and provisions" (column 0120) must equal the sum of "Performing exposures with forbearance measures - Accumulated impairment and provisions" (column 0130) and "Non-performing exposures with forbearance measures - Accumulated impairment, accumulated negative changes in impairment due to credit risk and provisions" (column 0140).

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  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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 SR19.00.04 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

Rows

  • R0010Debt securities
  • R0070Loans and advances
  • R0180Debt instruments at cost or at amortised cost
  • R0181Debt securities
  • R0191Loans and advances
  • R0201Debt instruments at fair value through other comprehensive income or through equity subject to impairment
  • R0330Debt instruments other than held for trading or trading
  • R0340Loan commitments given

Columns

  • C0120Accumulated impairment, accumulated negative changes in fair value due to credit risk and provisions
  • C0130Performing exposures with forbearance measures - Accumulated impairment and provisions
  • C0140Non-performing exposures with forbearance measures - Accumulated impairment, accumulated negative changes in impairment due to credit risk and provisions

A worked example

With simple numbers.

Illustrative values
Performing exposures with forbearance measures - Accumulated impairment and provisions1,200
Non-performing exposures with forbearance measures - Accumulated impairment, accumulated negative changes in impairment due to credit risk and provisions800
Together2,000
What the rule then expects

Accumulated impairment, accumulated negative changes in fair value due to credit risk and provisions 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 and detailed breakdowns) (RFB004) return on Bank of England banking taxonomy 4.1.1. The Bank of England applies it to intragroup financial reporting (core and detailed breakdowns) (RFB004) 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_v3087_h: T1: SR19.00.04.02; rows: {SR19.00.04.02, r0010-0201;0330-0340}; Expression: {SR19.00.04.02, c0120} = {SR19.00.04.02, c0130} + {SR19.00.04.02, c0140}

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

{t: SR19.00.04.02, c: 0120} = {t: SR19.00.04.02, c: 0130} + {t: SR19.00.04.02, c: 0140}

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

scope({t: SR19.00.04.02, r: 0010; 0070; 0180; 0181; 0191; 0201; 0330; 0340, 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.
