• A Fixed Indexed Annuity (FIA) is a fixed annuity that provides a guaranteed lifetime income and interest rate while preserving and protecting your premium. You do not pay taxes on your premium or interest until you take withdrawals or receive income. Unlike traditional fixed annuities, additional interest may be earned based on positive changes in commonly used financial indices such as the S&P 500 or the Dow Jones Industrial Average. Because the annuity you purchase is indexed, your premium and credited interest can never be lost due to an economic downturn.
