This represents the calculation of end exposure value post CRM post off-Balance sheet conversion factors (SC07.00.01.01, SC09.01.01.01, Bank of England check boe_b0141-1_ss)

A blocking check on the 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 for SDDTs (PRA116) return.

Line4 Check runs it on the own funds for SDDTs (PRA116) return, proven on test files, check by check: the same outcome on all three test files of that return.

The rule in plain words

This represents the calculation of end exposure value post CRM post off-Balance sheet conversion factors

In each of 57 rows (listed below) of Credit and counterparty credit risks and free deliveries: standardised approach to capital requirements for SDDTs (CR SA SDDT) (SC07.00.01.01): "Exposure value" (column 0200) must equal "Fully adjusted exposure value (E*)" (column 0150) minus 0.9 multiplied by "10%" (column 0160) minus 0.8 multiplied by "20%" (column 0170) minus 0.6 multiplied by "40%" (column 0171) minus 0.5 multiplied by "50%" (column 0180).

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 SC07.00.01 as reported.

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: SC07.00.01.01, c: 0200} = {t: SC07.00.01.01, c: 0150} - (0.9 * {t: SC07.00.01.01, c: 0160}) - (0.8 * {t: SC07.00.01.01, c: 0170}) - (0.6 * {t: SC07.00.01.01, c: 0171}) - (0.5 * {t: SC07.00.01.01, c: 0180})
