Operational risk: part 2 - minimum required capital (OPR): values must agree (OF16.00.01.02, OF16.00.01.03, OF16.00.01.06 and others, Bank of England check boe_b0443)

A warning on the operational risk: part 2 - minimum required capital (OPR) (OF16.00.01.02), operational risk: part 3 - business indicator component (OPR) (OF16.00.01.03), operational risk: part 6 - internal loss multiplier (OPR) (OF16.00.01.06), operational risk: part 2 - minimum required capital (OPR) (SC16.00.01.02), operational risk: part 3 - business indicator component (OPR) (SC16.00.01.03) and operational risk: part 6 - internal loss multiplier (OPR) (SC16.00.01.06) 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 shows what the Operational risk capital requirements (ORC) would be by multiplying the BIC and the ILM based on losses greater than £20,000

In Operational risk: part 2 - minimum required capital (OPR) (OF16.00.01.02): "Minimum required operational risk capital (ORC)" in column "ILM (losses greater than £20,000)" (row 0010, column 0020) must equal "Business Indicator Component (BIC)" in column "Amount" (row 0010, column 0010) in Operational risk: part 3 - business indicator component (OPR) (OF16.00.01.03) multiplied by "ILM (losses greater than £20,000)" in column "Amount" (row 0010, column 0010) in Operational risk: part 6 - internal loss multiplier (OPR) (OF16.00.01.06).

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.

This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it. It runs only when your filing indicators mark OF16.00.01.02, OF16.00.01.03 and OF16.00.01.06 as reported.
