Transitional provisions (CA5.1): every value in the cells it covers must be zero or more (CP05.01.04.01, Bank of England check v3689_s)

A warning on the transitional provisions (CA5.1) template (CP05.01.04.01), in the capital+ actuals and forecasts (PRA112) return.

Line4 Check runs it on the capital+ actuals and forecasts (PRA112) return, proven on test files, check by check: the same outcome on all eight test files of that return.

The rule in plain words

In Transitional provisions (CA5.1) (CP05.01.04.01): every value in the cells it covers must be zero or more.

What to do if your return fails it

  1. 01Open the table below and find the cells the rule reads.
  2. 02Look for a value below zero in these cells, such as an amount entered as a negative number.
  3. 03It runs only when your filing indicators mark CP05.01.04 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.
