Part 1: Overview: values to report together, or not at all (SR808.09.08.01, SR808.09.08.02, Bank of England check boe_b1147_m)

A blocking check on the part 1: Overview (SR808.09.08.01) and part 2: Exposures to relevant financial institutions relating to pension liability (SR808.09.08.02) templates, in the excluded activities and prohibitions (RFB008) return.

Line4 Check runs it on the excluded activities and prohibitions (RFB008) 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 1: Overview (SR808.09.08.01): either "There has been no use of the exemptions in article 14(4)(b)(iii) or (iv) of the Order during this reporting period" in column "Current period" (row 010, column 010) is "No use of the exemptions in article 14(4)(b)(iii) or (iv) of the Order" and "Description of type of exposure" (column 015), "Amount of exposures" (column 020) and "Relevant financial institution to which the RFB has exposure" (column 030) in Part 2: Exposures to relevant financial institutions relating to pension liability (SR808.09.08.02) is left empty, or "There has been no use of the exemptions in article 14(4)(b)(iii) or (iv) of the Order during this reporting period" in column "Current period" (row 010, column 010) is "Use of the exemptions in article 14(4)(b)(iii) or (iv) of the Order" and "Description of type of exposure" (column 015), "Amount of exposures" (column 020) and "Relevant financial institution to which the RFB has exposure" (column 030) in Part 2: Exposures to relevant financial institutions relating to pension liability (SR808.09.08.02) is reported.

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. 02Report these values together, or leave them all out.
  3. 03It runs only when your filing indicators mark SR808.09.08 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_b1147_m: T1: SR808.09.08.01; T2: SR808.09.08.02; Expression: ({SR808.09.08.01, r010, c010} = [boe_SR:x6029] and empty({SR808.09.08.02, c015-030})) or ({SR808.09.08.01, r010, c010} = [boe_SR:x6030] and not(empty({SR808.09.08.02, c015-030})))

The Bank of England's formula. Cells are written as {t: table, r: row, c: column}.

({t: SR808.09.08.01, r: 010, c: 010} = [boe_SR:x6029] and isNull({t: SR808.09.08.02, c: 015; 020; 030})) or ({t: SR808.09.08.01, r: 010, c: 010} = [boe_SR:x6030] and not(isNull({t: SR808.09.08.02, c: 015; 020; 030})))

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.
