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, Bank of England check boe_b0050_ss)

A blocking check on the credit and counterparty credit risks and free deliveries: standardised approach to capital requirements for SDDTs (CR SA SDDT) template (SC07.00.01.01), 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

FULLY ADJUSTED EXPOSURE VALUE is the sum of NET EXPOSURE AFTER CRM SUBSTITUTION EFFECTS PRE CONVERSION FACTOR, VOLATILITY ADJUSTMENTS and Adjusted FINANCIAL COLLATERAL

In each of 29 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): "Fully adjusted exposure value (E*)" (column 0150) must equal the sum of "Net exposure after CRM substitution effects pre conversion factors" (column 0110), "Volatility adjustment to the exposure" (column 0120) and "(-) Financial collateral: adjusted value (Cvam)" (column 0130).

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 table 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  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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.

A worked example

With simple numbers.

Illustrative values
Net exposure after CRM substitution effects pre conversion factors1,200
Volatility adjustment to the exposure800
(-) Financial collateral: adjusted value (Cvam)450
Together2,450
What the rule then expects

Fully adjusted exposure value (E*) must then be 2,450.

2,450Passes
2,550Fails

A file that reports 2,450 passes. One that reports 2,550 fails, by 100.

The numbers are illustrative, reported to the unit, so the rounding tolerance does not change the result.

Which returns it applies to

Line4 Check runs it on the own funds for SDDTs (PRA116) return on Bank of England banking taxonomy 4.1.1. The Bank of England applies it to own funds for SDDTs (PRA116) returns, as a blocking check.

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: 0150} = {t: SC07.00.01.01, c: 0110} + {t: SC07.00.01.01, c: 0120} + {t: SC07.00.01.01, c: 0130}

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.
