Part 3: Security interest over investments (article 6(6)(a)): "Peak daily value" must not be less than "Average daily value" (SR808.02.08.03, Bank of England check boe_b1089_m)

A warning on the part 3: Security interest over investments (article 6(6)(a)) template (SR808.02.08.03), in the excluded activities and prohibitions (RFB008) return.

Line4 Check does not run it on the excluded activities and prohibitions (RFB008) return. On items no template of the return has. It reads only concepts or members that none of the return’s templates has, so it can never apply to it.

Line4 Check does not run this check yet, so the button checks your return against the Bank's other checks for it. The validation run when you submit includes this one.

The rule in plain words

In Part 3: Security interest over investments (article 6(6)(a)) (SR808.02.08.03): "Peak daily value" (column 020) must not be less than "Average daily value" (column 010).

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. 03This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it.

The cells it reads

Which returns it applies to

It is an active check of the Bank's for the excluded activities and prohibitions (RFB008) return on Bank of England banking taxonomy 4.1.1. Line4 Check does not run it yet, for the reason above. The Bank of England applies it to excluded activities and prohibitions (RFB008) returns, as a warning.

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_b1089_m: T1: SR808.02.08.03; rows: {SR808.02.08.03, r160-190}; Expression: {SR808.02.08.03, c020} >= {SR808.02.08.03, c010}

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.
