The rule in plain words
In Capital adequacy - memorandum items (CA4) (C04.00.01.01): every value in 92 rows (listed below) in column "Amount" (column 0010) must be zero or more.
What to do if your return fails it
- 01Open the tables below and find the cells the rule reads.
- 02Look for a value below zero in these cells, such as an amount entered as a negative number.
- 03It runs only when your filing indicators mark C04.00.01 as reported.
- 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
