A blocking check on the intragroup financial reporting (detailed breakdown) Part 1: Interest income and expenses by instrument and counterparty sector template (SR16.01.04.01), 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.

Check your file for this ruleWhat to do if it fails

The rule in plain words

In each of "Income" (column 0010), "Expenses" (column 0020), "Income" (column 0030) and "Expenses" (column 0040) of Intragroup financial reporting (detailed breakdown) Part 1: Interest income and expenses by instrument and counterparty sector (SR16.01.04.01): "INTEREST" (row 0270) must equal the sum of 8 cells (listed below).

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  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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 SR16.01.04 as reported.
  6. 06This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.

A file that reports 3,100 passes. One that reports 3,200 fails, by 100.

The numbers are illustrative, reported to the unit, so the rounding tolerance does not change the result.
