Detailed information on securitisations by approach (CR SEC Details 2): a value must not be more than another (C14.01.01.01, Bank of England check v7747_s)

A warning on the detailed information on securitisations by approach (CR SEC Details 2) template (C14.01.01.01), in the own funds (PRA001) return.

Line4 Check runs it on the own funds (PRA001) return, proven on test files, check by check: the same outcome on all three test files of that return.

The rule in plain words

In Detailed information on securitisations by approach (CR SEC Details 2) (C14.01.01.01): every value in "(-) Exposure value deducted from own funds" (column 0420), "(-) Reduction due to risk weight cap" (column 0431) and "(-) Reduction due to overall cap" (column 0432) on 4 sheets must be zero or less.

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. 02Compare the values in your return. If the first is bigger than it may be, one of them is wrong: check both before you change either.
  3. 03It runs only when your filing indicators mark C14.01.01 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.
