Annuity Purchase commissions or fees

[Buzz]

For purposes of purchasing an annuity under a plan termination that meets the "safest annuity provider" conditions, what is the experience on the commission percentage or flat fee that brokers charge for a small population?

For example, for a plan with a liability of less than $1 million, what type of charge could the plan expect?

If the liability is between $1 million and $5 million, would the rate be the same?

I have seen 6% commission in the past but have not processed one through a broker for a while. Thanks!
