Variable life has, historically, been the most popular, with the universal life type of policy design. The major difference between a universal life and a variable universal life is that the policyholder bears the primary responsibility for the investment selection. The company will offer choices of investments (sub-accounts) similar to, but not the same as, mutual funds. There will normally be a domestic stock account, foreign stock account, fixed income account, and money market type of account. Some companies will offer a wider variety of choices than others.
