If a bond is called, put or exchanged before maturity, the bondholder only earns interest on the time that has elapsed between purchasing the bond and its early redemption. The resulting yield is less than what would have been earned had the bond been held until maturity. NEWSLETTER Get market information, auction updates, new-issue alerts, and more.
