Unmatured, unredeemed Series E bonds accrue interest at a market-based yield or the applicable guaranteed minimum investment yield, whichever is greater. A guaranteed minimum investment yield in effect at the start of an original or extended maturity period is guaranteed to the end of that original or extended maturity period. See Market-based Yields . Series E bonds had varying original maturity periods depending on their issue dates, ranging from 10 years for the oldest bonds to 5 years for the last ones issued. Series E bonds issued from May 1941 to November 1965 were granted three 10-year extended maturity periods.
