Yes, I understand it is pooled. What I saying is, if Carrier X has 1,000 large group, and 950 of them are self-insured, then it only has to get a pool of 50 groups into line. I guess you might see self-funded groups subsidizing insured groups on administrative costs for the carrier.
Self funded do not count towards the 85/15. So in this example the carrier is doing the ratio on 50 groups. Bet a large pepperoni pizza that this carrier will fail.
