The rule in plain words
In row "Total positions" (0010) of Market risk: internal models (MKR IM) (C24.00.01.01): "FLOOR" (column 0090) must equal the larger of "Assumed charge for ctp floor - weighted net long positions after cap" (column 0170) and "Assumed charge for ctp floor - weighted net short positions after cap" (column 0180) multiplied by 0.08.
The headline gives only the template and the kind of check, because the rule is too long to say in a headline. The plain words above say all of it.
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 C24.00.01 as reported.
