The rule in plain words
Deriving total risk exposure from own funds requirements
In row "Total Residual Risk Add-on (RRAO)" (0010) of Market risk: ASA residual risk add on (AS9 RRAO) (OF91.09.01.01): "Total risk exposure amount" (column 0030) must equal "Own funds requirements" (column 0020) 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 OF91.09.01 as reported.
