I'm pretty familiar with minimum premium plans and would be glad to help.
In a traditional minimum premium plan the insurance company breaks the cost down to three components, the "minimum premium" or MP, the claims cap (usually capped monthly with annual accumulation, and the terminal liablity factor. The MP consists of the insurance company retention (admin), pooling charges, and any other fees. You will pay your MP monthly plus the prior month's claims up to the cap. Usually the first year claims are split 75% to 80% into the claims cap, 20% to 25% into the terminal liablity. If you cancel at the end of year one, your only liability should be the terminal liability fee. In essence, you are paying the retention/pooling, claims costs, and you are holding the reserve instead of the insurance company.
What you have described I would call a fully insured retrospectively rated plan with a "retro rate". They are going to bill you a portion of the premium during the year. At some point after the end of the policy year they will do a settlement. Up front you need to know how the settlement process will work, ie. the formula, reserve factors, etc. When will they do the settlement? 60 days with a substantial IBNR adjustment or will they wait 120 to 150 days to have fully incurred claims? What is their retention (admin) cost? Is is guaranteed/ How may it change from the initial projection to final settlement? Same for pooling? Plus, there is a charge for the "retro", a cost of money factor, since the client is holding the reserve.
I don't see anything wrong with the arrangement perse. The problems occur when the parties aren't on the same page, and don't understand, and later disagree on how the plan is supposed to work.

We have a broker who is trying to introduce a "minimum premium payment" health plan. This is a fully insurance plan with self insured characteristics. Specifially, 80% of the premium goes to the health care vendor and 20% is held in a reserve (in our bank). At year end, when we "true up" the plan, based on our experience rating, we may be able to keep a certain portion of the reserve money to use for future medical plan expenses.
Has anyone had any experience with this type of plan? What are your thoughts? Any red flags we need to look for? This one is new to me.
