Own funds requirements (CA2): every value in the cells it covers must be zero or more (CP02.00.05.01, Bank of England check v3686-2_s)

A blocking check on the own funds requirements (CA2) template (CP02.00.05.01), in the capital+ forecast semi annual (PRA113) return.

Line4 Check runs it on the capital+ forecast semi annual (PRA113) 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 Own funds requirements (CA2) (CP02.00.05.01): 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 CP02.00.05 as reported.
  4. 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
