A form of whole life insurance, variable life insurance provides permanent protection to the beneficiary upon the death of the policy holder. This type of insurance is generally the most expensive type of cash-value insurance because it allows you to allocate a portion of your premium dollars to a separate account comprised of various instruments and investment funds within the insurance company's portfolio such stocks, bonds, equity funds, money market funds and bond funds. In addition, because of investment risks, variable policies are considered securities contracts and are regulated under the federal securities laws; therefore, they must be sold with a prospectus.
