The PRA may, in the exercise of sound supervisory judgement -

(a) determine that a group or a body is a G-SII, notwithstanding the fact that the group or the body is not recognised as a G-SII in accordance with the PRA's identification methodology and the sub-categories which the PRA has defined;

(b) allocate a G-SII to a higher sub-category to that indicated by its score under the identification methodology and the sub-categories which the PRA has defined.
