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), geographical breakdown of exposures by residence of the obligor (SA EXPOSURES) (CR GB 1) (SC09.01.01.01) and own funds requirements for SDDTs (CA2 SDDT) (SC02.00.01.01) 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.

Check your file for this ruleWhat to do if it fails

The rule in plain words

Check that total exposures (row 0010) is greater than or equal to the row 'of which: SME' (0020) for the columns stated

In each of 16 columns (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): "Total exposures" (row 0010) must not be less than "of which: SME" (row 0020).

What to do if your return fails it

  1. 01Open the tables below and find the cells the rule reads.
  2. 02Compare the values in your return. If the first is smaller than it may be, one of them is wrong: check both before you change either.
  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 SC07.00.01 as reported.
  5. 05This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

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}.

{t: SC07.00.01.01, r: 0010} >= {t: SC07.00.01.01, r: 0020}

Checks like this one, run at the point of submission, are the first step to real-time supervision. Line4 builds SupTech software for financial regulators that runs checks like these as each return arrives.
