Credit and counterparty credit risks and free deliveries: standardised approach to capital requirements for SDDTs (CR SA SDDT): a total must equal the sum of its parts (SC07.00.01.01, SC09.01.01.01, Bank of England check boe_b0069_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

Regulatory Real Estate exposures should be the sum of residential exposures of which: materially and of which: not-materially dependent on the cash flows generated by the property

In each of 22 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): "of which: Real estate exposures - regulatory residential real estate exposures" (row 0330) must equal the sum of "of which: not materially dependent on the cash flows generated by the property" (row 0331) and "of which: materially dependent on the cash flows generated by the property" (row 0332).

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.

What to do if your return fails it

  1. 01Open the tables below and find the cells the rule reads.
  2. 02Add up the parts in your return and compare the result with the total.
  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.
  4. 04The Bank of England allows a small rounding difference, worked out from the decimals each value is reported with.
  5. 05It runs only when your filing indicators mark SC07.00.01 as reported.
  6. 06This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

Which returns it applies to

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, r: 0330} = sum({t: SC07.00.01.01, r: 0331; 0332})

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

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.
