Series EE bonds mature after 30 years, meaning they can earn interest for that period of time. EE bonds are sold for half of face value and the U.S. Treasury Department guarantees they will reach face value after 20 years. Bonds must be owned for at least one year before redemption.
An intermediate-term bond is one that matures not in the short-term or in the long-term. It matures in the medium term. Just what the intermediate term is, that's not as easy to define. Some say three to 10 years. Some say the intermediate term can last for 15 years. The length of time to maturity really does matter. Those who know bonds understand that the maturity date is the point at which the bond pays back the principal or face value of the bond.
