Well, a couple of things. One, is that these are not "Government estimated costs" and not estimated at all. These are actual first-year (proposed) premiums. Second, these companies will not be paid by anyone to "make up the difference" if their actual costs go higher. It is not any variation of cost-plus and there will be no re-negotiated contracts for the year. Premium stability is another issue altogether and as I've said, this will be interesting to watch.
Well that didn’t take long:
