"Peak daily value" must not be less than "Average daily value" (SR808.02.08.04, Bank of England check boe_b1090_m)

A warning on the part 4: Title transfer collateral arrangements in relation to investments (article 6(6)(b)) template (SR808.02.08.04), 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.

Check your file for this ruleWhat to do if it fails

The rule in plain words

In each of "Entering into a title transfer collateral arrangement in relation to investments" (row 200), "Acquiring equivalent investments in accordance with a title transfer collateral arrangement" (row 210), "Enforcing a title transfer collateral arrangement in relation to investments" (row 220) and "Selling the investments which are subject to a title transfer collateral arrangement" (row 230) of Part 4: Title transfer collateral arrangements in relation to investments (article 6(6)(b)) (SR808.02.08.04): "Peak daily value" (column 020) must not be less than "Average daily value" (column 010).

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 SR808.02.08 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.
