Line4 Check runs it on the use of financial market infrastructures (RFB007) return, proven on test files, check by check: the same outcome on all seven test files of that return.

Check your file for this ruleWhat to do if it fails

The rule in plain words

In row "Total for all entities in the RFB sub-consolidation group other than ring-fenced banks" (row 010) of Part 1: Aggregate information (SR807.01.07.01): "Peak default fund contribution (where made)" (column 130) must not be less than "Average default fund contribution (where made)" (column 120).

What to do if your return fails it

  1. 01Open the table below and find the cells the rule reads.
  2. 02Compare the values in your return. If the first is smaller than it may be, one of them is wrong: check both before you change either.
  3. 03It runs only when your filing indicators mark SR807.01.07 as reported.
  4. 04This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it.
