"Own funds requirements" must equal "Price difference exposure due to unsettled transactions" multiplied by 0.5 (C11.00.01.01, Bank of England check v0496_m)

A blocking check on the settlement/delivery risk (CR SETT) template (C11.00.01.01), in the own funds (PRA001) return.

Line4 Check runs it on the own funds (PRA001) return, proven on test files, check by check: the same outcome on all three test files of that return.

The rule in plain words

In each of "Transactions unsettled between 16 and 30 days (Factor 50%)" (row 0040) and "Transactions unsettled between 16 and 30 days (Factor 50%)" (row 0100) of Settlement/delivery risk (CR SETT) (C11.00.01.01): "Own funds requirements" (column 0030) must equal "Price difference exposure due to unsettled transactions" (column 0020) multiplied by 0.5.

This is a blocking check. A return that fails it is normally rejected, so fix it before you submit. It runs only when your filing indicators mark C11.00.01 as reported.

v0496_m: [C11.00.01.01 (r0040;0100)] {c0030} = {c0020} * 50%

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

{t: C11.00.01.01, c: 0030} = {t: C11.00.01.01, c: 0020} * 0.5

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