The rule in plain words
Deriving total risk exposure from own funds requirements
In row "Total Equity risk (EQU)" (0010) of Market risk: ASA equity risk (AS5 EQ) (OF91.05.01.01): "Total risk exposure amount" (column 0170) must equal "Own funds requirements" (column 0160) multiplied by 12.5.
This is a blocking check. A return that fails it is normally rejected, so fix it before you submit. It runs only when your filing indicators mark OF91.05.01 as reported.
