The sum of "SENIOR" on 4 sheets must not be more than "AMOUNT" in Detailed information on securitisations (CR SEC Details) (C14.01.01.01, C14.00.01.01, Bank of England check v7372_m)

A warning on the detailed information on securitisations by approach (CR SEC Details 2) (C14.01.01.01) and detailed information on securitisations (CR SEC Details) (C14.00.01.01) templates, 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): the sum of "SENIOR" (column 0310) on 4 sheets must not be more than "AMOUNT" (column 0230) in Detailed information on securitisations (CR SEC Details) (C14.00.01.01).

What to do if your return fails it

  1. 01Open the tables 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. 03The Bank of England allows a small rounding difference, worked out from the decimals each value is reported with.
  4. 04It runs only when your filing indicators mark C14.00.01 and C14.01.01 as reported.
  5. 05This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it.
