Geographical breakdown of exposures by residence of the obligor: SA exposures (OF CR GB 1): a conditional check (OF09.01.01.01, OF07.00.01.01, SC07.00.01.01 and others, Bank of England check boe_b0262)

A blocking check on the geographical breakdown of exposures by residence of the obligor: SA exposures (OF CR GB 1) (OF09.01.01.01), credit and counterparty credit risks and free deliveries: standardised approach to capital requirements (CR SA) (OF07.00.01.01), credit and counterparty credit risks and free deliveries: standardised approach to capital requirements for SDDTs (CR SA SDDT) (SC07.00.01.01) 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

If exposure value reported in OF07.00 for exposures in default and total exposures reported in OF09.01 for all countries are greater than zero, then the reported exposures in default in OF09.01 should be greater than zero

In Geographical breakdown of exposures by residence of the obligor: SA exposures (OF CR GB 1) (OF09.01.01.01): if "Total exposures" in column "Original exposure pre conversion factors" (row 0010, column 0010) on sheet "Exposures in default" (sheet 0011) in Credit and counterparty credit risks and free deliveries: standardised approach to capital requirements (CR SA) (OF07.00.01.01) is more than 0 and "Total exposures" in column "Original exposure pre conversion factors" (row 0170, column 0010) (where country where the exposure is generated is "All countries") is more than 0, "Total exposures" in column "Defaulted exposures" (row 0170, column 0020) (where country where the exposure is generated is "All countries") must be more than zero.

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 tables below and find the cells the rule reads.
  2. 02The check applies only when its first part holds in your return. When it does, the second part must hold too: fix the second part, or correct the first.
  3. 03It runs only when your filing indicators mark OF07.00.01 and OF09.01.01 as reported.
  4. 04This 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.

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

if {t: OF07.00.01.01, r: 0010, c: 0010, z: 0011} > 0 and {t: OF09.01.01.01, r: 0170, c: 0010, filter: [eba_dim:CEG] = [eba_GA:x1]} > 0 then {t: OF09.01.01.01, r: 0170, c: 0020, filter: [eba_dim:CEG] = [eba_GA:x1]} > 0 else true()

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.
