Intragroup financial reporting (detailed breakdown) Breakdown of financial liabilities: two values must match (SR08.01.04.01, SR10.00.04.01, Bank of England check boe_b0109_m)

A blocking check on the intragroup financial reporting (detailed breakdown) Breakdown of financial liabilities (SR08.01.04.01) and intragroup financial reporting (detailed breakdown) Derivatives (SR10.00.04.01) templates, in the intragroup financial reporting (core and detailed breakdowns) (RFB004) return.

Line4 Check runs it on the intragroup financial reporting (core and detailed breakdowns) (RFB004) 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 Intragroup financial reporting (detailed breakdown) Breakdown of financial liabilities (SR08.01.04.01): "Derivatives" in column "Held for trading" (row 0010, column 0010) must equal "DERIVATIVES" in column "Financial liabilities held for trading and trading" (row 0290, column 0020) in Intragroup financial reporting (detailed breakdown) Derivatives (SR10.00.04.01).

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. 02The two values must be the same. Find which of the two is right, and correct the other one.
  3. 03It runs only when your filing indicators mark SR08.01.04 and SR10.00.04 as reported.
  4. 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
