Part 2: trade finance exposures: a total must equal the sum of its parts (SR808.07.08.02, Bank of England check boe_b1106_m)

A blocking check on the part 2: trade finance exposures template (SR808.07.08.02), 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 each of "Exposures to relevant financial institutions relating to trade finance incurred over the period" (column 010) and "Exposures to relevant financial institutions relating to trade finance outstanding at end of period" (column 020) of Part 2: trade finance exposures (SR808.07.08.02): "Total" (row 040) must equal the sum of "Letters of credit" (row 010), "Guarantees" (row 020) and "Other (utilising Article 15 of the Excluded Activities and Prohibitions Order)" (row 030).

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. 02Add up the parts in your return and compare the result with the total.
  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.
  4. 04The Bank of England allows a small rounding difference, worked out from the decimals each value is reported with.
  5. 05It runs only when your filing indicators mark SR808.07.08 as reported.
  6. 06This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

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

{t: SR808.07.08.02, r: 040} = sum({t: SR808.07.08.02, r: 010; 020; 030})

Where it applies, in the Bank's words (its scope):
