Part 2: Commodity trading (article 5(1)): every value in the cells it covers must be zero or more (SR808.01.08.02, Bank of England check boe_b1073_s)

The rule in plain words

What to do if your return fails it

1. 01Open the table below and find the cells the rule reads.
2. 02Look for a value below zero in these cells, such as an amount entered as a negative number.
3. 03It runs only when your filing indicators mark SR808.01.08 as reported.
4. 04This 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

Line4 Check runs it on the excluded activities and prohibitions (RFB008) return on Bank of England banking taxonomy 4.1.1. 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_b1073_s: T1: SR808.01.08.02; rows: {SR808.01.08.02, r040-050}; columns: {SR808.01.08.02, c010-040}; Expression: {SR808.01.08.02} >= 0

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.
