Part 1: Overview: a check on its values (SR808.06.08.01, SR808.06.08.02, SR808.06.08.03 and others, Bank of England check boe_b1144_m)

A blocking check on the part 1: Overview (SR808.06.08.01), part 2: Transactions with Account Holders (SR808.06.08.02), part 3: RRR conditions (SR808.06.08.03) and part 4: breaches (SR808.06.08.04) 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 (SR808.06.08.01): either "There has been no use of the exemptions in articles 9-12 of the Order during this reporting period" in column "Current period" (row 010, column 010) is "No use of the exemptions in articles 9-12 of the Order" and 9 rows (listed below) in "Current period" (column 010), "Current period" (column 020), "Financial assets" (column 030) and "Financial liabilities" (column 040) in Part 2: Transactions with Account Holders (SR808.06.08.02) is left empty and 6 rows (listed below) in column "Current period" (column 010) in Part 3: RRR conditions (SR808.06.08.03) is left empty and "Number of breaches during current period - where fair value measurement is not constituted by IFRS Level 1 & 2 inputs" (row 170) and "Number of breaches during current period - trading venue requirements for transactions under articles 10 and 11" (row 180) in column "Current period" (column 010) in Part 4: breaches (SR808.06.08.04) is left empty, or "There has been no use of the exemptions in articles 9-12 of the Order during this reporting period" in column "Current period" (row 010, column 010) is "Use of the exemptions in articles 9-12 of the Order" and 9 rows (listed below) in "Current period" (column 010), "Current period" (column 020), "Financial assets" (column 030) and "Financial liabilities" (column 040) in Part 2: Transactions with Account Holders (SR808.06.08.02) is reported or 6 rows (listed below) in column "Current period" (column 010) in Part 3: RRR conditions (SR808.06.08.03) is reported or "Number of breaches during current period - where fair value measurement is not constituted by IFRS Level 1 & 2 inputs" (row 170) and "Number of breaches during current period - trading venue requirements for transactions under articles 10 and 11" (row 180) in column "Current period" (column 010) in Part 4: breaches (SR808.06.08.04) 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.

This is a blocking check. A return that fails it is normally rejected, so fix it before you submit. It runs only when your filing indicators mark SR808.06.08 as reported.

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.
