R0092 should be less than or equal to r0090 as it's an 'of which' row (OF09.01.01.01, SC09.01.01.01, Bank of England check boe_b0609)

A blocking check on the geographical breakdown of exposures by residence of the obligor: SA exposures (OF CR GB 1) (OF09.01.01.01) and geographical breakdown of exposures by residence of the obligor (SA EXPOSURES) (CR GB 1) (SC09.01.01.01) templates, in the own funds (PRA001) and own funds for SDDTs (PRA116) returns.

Line4 Check runs it on the own funds (PRA001) and own funds for SDDTs (PRA116) returns, proven on test files, check by check: the same outcome on all six test files of those returns.

The rule in plain words

r0092 should be less than or equal to r0090 as it's an 'of which' row

In each of 10 columns (listed below) of Geographical breakdown of exposures by residence of the obligor: SA exposures (OF CR GB 1) (OF09.01.01.01): "Real estate exposures" (row 0090) must not be less than "of which: Regulatory commercial real estate" (row 0092).

What to do if your return fails it

  1. 01Open the tables below and find the cells the rule reads.
  2. 02Compare the values in your return. If the first is smaller than it may be, one of them is wrong: check both before you change either.
  3. 03The Bank of England allows a small rounding difference, worked out from the decimals each value is reported with.
  4. 04It runs only when your filing indicators mark OF09.01.01 as reported.
  5. 05This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

Which returns it applies to

Line4 Check runs it on the own funds (PRA001) and own funds for SDDTs (PRA116) returns on Bank of England banking taxonomy 4.1.1. The Bank of England applies it to own funds for SDDTs (PRA116) and own funds (PRA001) returns, as a blocking check.

The Bank’s own words and formula

The first paragraph of the plain words above is the Bank of England’s own, word for word, from its list of validations. The second spells out its formula, with each cell named from its templates.

Show the formulaShow

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

{t: OF09.01.01.01, r: 0090} >= {t: OF09.01.01.01, r: 0092}

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

scope({t: OF09.01.01.01, c:0010;0020;0040;0050;0055;0060;0061;0070;0075;0090, f: banking, fv: banking_reporting})

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.
