My first instinct is that it sounds pretty good as a way for more tax deferred retirement savings.
I am concerned about one thing.
The email talks about a "minimum balance" within the MBCBP.
What does that mean? How do you negotiate a minimum balance? Minimum at retirement? Minimum at date of signing? Do you have to retire with a certain number of years to get the minimum balance? If it is minimum at retirement then that means that someone who retires 10 days after date of signing will get that minimum balance. So you could never contribute anything and get the minimum balance? Could you make terrible investment choices and still get the minimum balance?
I think we need an explanation of the minimum balance concept. Unless I am misunderstanding, the minimum balance is fundamental to the whole concept.
