This represents the BIC for Bucket 2 when the BI range is between £0.88bn and £26bn, using a 15% marginal coefficient (OF16.00.01.03, SC16.00.01.03, Bank of England check boe_b0910)

A warning on the operational risk: part 3 - business indicator component (OPR) (OF16.00.01.03) and operational risk: part 3 - business indicator component (OPR) (SC16.00.01.03) 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

This represents the BIC for Bucket 2 when the BI range is between £0.88bn and £26bn, using a 15% marginal coefficient

In Operational risk: part 3 - business indicator component (OPR) (OF16.00.01.03): if "Business Indicator (BI)" in column "Component value" (row 0010, column 0050) in Operational risk: part 4 - business indicator and subcomponents (OPR) (OF16.00.01.04) is more than 880 multiplied by 1000 multiplied by 1000 and "Business Indicator (BI)" in column "Component value" (row 0010, column 0050) in Operational risk: part 4 - business indicator and subcomponents (OPR) (OF16.00.01.04) is not more than 26000 multiplied by 1000 multiplied by 1000, "Bucket Amount" in column "Bucket 2 - 15%" (row 0020, column 0030) must equal "Business Indicator (BI)" in column "Component value" (row 0010, column 0050) in Operational risk: part 4 - business indicator and subcomponents (OPR) (OF16.00.01.04) minus 880 multiplied by 1000 multiplied by 1000 multiplied by 0.15; otherwise if "Business Indicator (BI)" in column "Component value" (row 0010, column 0050) in Operational risk: part 4 - business indicator and subcomponents (OPR) (OF16.00.01.04) is more than 26000 multiplied by 1000 multiplied by 1000, "Bucket Amount" in column "Bucket 2 - 15%" (row 0020, column 0030) must equal 26000 multiplied by 1000 multiplied by 1000 minus 880 multiplied by 1000 multiplied by 1000 multiplied by 0.15; otherwise "Bucket Amount" in column "Bucket 2 - 15%" (row 0020, column 0030) must equal 0.

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. 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 OF16.00.01.03 and OF16.00.01.04 as reported.
  5. 05This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it.

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: OF16.00.01.04, r: 0010, c: 0050} > 880 * 1000 * 1000 and {t: OF16.00.01.04, r: 0010, c: 0050} <= 26000 * 1000 * 1000) then {t: OF16.00.01.03, r: 0020, c: 0030} = ({t: OF16.00.01.04, r: 0010, c: 0050} - 880 * 1000 * 1000) * 0.15 else if {t: OF16.00.01.04, r: 0010, c: 0050} > (26000 * 1000 * 1000) then {t: OF16.00.01.03, r: 0020, c: 0030} = (26000 * 1000 * 1000 - 880 * 1000 * 1000) * 0.15 else {t: OF16.00.01.03, r: 0020, c: 0030} = 0
