Information on derivatives, securities financing and long settlement transactions of SDDTs (CCR SDDT): values must agree (SC34.00.01.01, Bank of England check boe_b0093_ss)

A blocking check on the information on derivatives, securities financing and long settlement transactions of SDDTs (CCR SDDT) template (SC34.00.01.01), 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

Derivative transactions not cleared through a CCP should be equal to total derivatives less those cleared through a QCCP and those cleared through a non-QCCP

In each of "Notional amounts" (column 0010), "Long positions" (column 0020), "Short positions" (column 0030) and "AMOUNT" (column 0060) of Information on derivatives, securities financing and long settlement transactions of SDDTs (CCR SDDT) (SC34.00.01.01): "Derivative transactions not cleared through a CCP" (row 0110) must equal "of which: derivative transactions" (row 0020) minus "of which: cleared through a QCCP" (row 0030) minus "of which: cleared through a non-QCCP" (row 0040).

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 blocking check. A return that fails it is normally rejected, so fix it before you submit. It runs only when your filing indicators mark SC34.00.01 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: SC34.00.01.01, r: 0110} = {t: SC34.00.01.01, r: 0020} - {t: SC34.00.01.01, r: 0030} - {t: SC34.00.01.01, r: 0040}

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