I think this goes beyond the level of what we’ll be asked on the exam. If this happens, one of two things will take place:
a) the firm will modify their internal processes so they can be verified
b) the firm won’t care - which turns into a very fundamental debate with no clear answer. I’d say they technically can still claim GIPS compliance.
Realistically, I’d guess 99% of firms will go with option a as their clients/prospective clients want to see verification and it will be much harder to market their services to clients if they’re not verified. If a client asks why they haven’t been verified they’ll have a difficult time explaining it…
