"""I find it hard to believe that someone would give up a 10 year old UL policy because COIs increased 5%."""
I don't find it so hard to believe, people will usually do what is right for them if explained properly
Well, how many people would really know how to properly analyze the replacement?
Unless it's a UL with a secondary guarantee (in which case the COI increase is meaningless), there are serious implications in starting a new surrender charge period and giving up one that is half way through. Will people really look at multiple illustrations with various funding levels, or if it's a good salesperson they will just accept what he or she shows them?
Believe it or not, I have an old client that it holding on to an old UL which he funded at minimum levels, even though he can get a new policy where his bottom line outlay for the coverage might be lower.
