Part 3: Detail of the exposures to intragroup counterparties (entity breakdown): a value must not be less than another (SR801.03.01.01, Bank of England check boe_v1678_m)

A blocking check on the part 3: Detail of the exposures to intragroup counterparties (entity breakdown) template (SR801.03.01.01), in the intragroup exposures (RFB001) return.

Line4 Check runs it on the intragroup exposures (RFB001) return, proven on test files, check by check: the same outcome on all eight test files of that return.

The rule in plain words

In Part 3: Detail of the exposures to intragroup counterparties (entity breakdown) (SR801.03.01.01): "Total original exposure" (column 050) must not be less than the size of the sum of "(-) Value adjustments and provisions" (column 200) and "(-) Exposures deducted from CET1 or Additional Tier1 items" (column 210) (ignoring its sign).

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. 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. 03It runs only when your filing indicators mark SR801.03.01 as reported.
  4. 04This 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 plain words above spell out the Bank’s formula, with each cell named from its templates. In the Bank of England’s list of validations, word for word:

boe_v1678_m: T1: SR801.03.01.01; Expression: {SR801.03.01.01, c050} >= abs({SR801.03.01.01, c200} + {SR801.03.01.01, c210})

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.
