Certain types of annuities may have benefits especially suited for retirees and pre-retirees. For example, a fixed index annuity (FIA) offers a guarantee of lifetime income*. Specifically, this is backed by the claims-paying ability of the issuing insurance company. Basically, an FIA is a contract or agreement that your money is kept in for a certain number of years. During this time, you cannot withdraw money from the annuity. However, after a certain time period, the insurance company will be able to send you payments. Indeed, the amount of the income payment may increase if you wait longer to withdraw money. Also, the FIA has the very useful benefit of protecting* your principal.
