Universal Life Insurance
Comprehensive life insurance is very flexable,
policyholders can specify the amount and the frequency of annuty payment (the more you pay, the less time you need to pay).
Your premiums cover the insurance portion, as well as the savings or investment component and the expense portion.
The declared interest on the investment portion changes along with the movement in interest rates
Moves in 1/4% interest steps are typical as banks and other financial institutions make similar moves.
