A blocking check on the credit and counterparty credit risks and free deliveries: standardised approach to capital requirements (CR SA) (OF07.00.01.01), geographical breakdown of exposures by residence of the obligor: SA exposures (OF CR GB 1) (OF09.01.01.01) and own funds requirements (CA2) (OF02.00.01.01) 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

Values reported in these columns should be greater than or equal to zero

In Credit and counterparty credit risks and free deliveries: standardised approach to capital requirements (CR SA) (OF07.00.01.01): every value in the cells it covers must be zero or more.

What to do if your return fails it

  1. 01Open the tables 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 OF07.00.01 as reported.
  4. 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
