§ 351.21 How are redemption values determined during any extended maturity period of Series EE savings bonds with issue dates prior to May 1, 1995?
The redemption value of a bond on a given interest accrual date during an extended maturity period or periods will be the higher of the values produced using either the applicable guaranteed minimum investment yield or the appropriate market-based variable investment yield. The calculation of these yields and the resulting redemption values are described below:
(a) Guaranteed minimum investment yield and resulting values during an extended maturity period. A bond may be subject to one guaranteed minimum investment yield during its original maturity period and to another such yield during each of its extended maturity periods.
(1) Bonds entering an extended maturity period from May 1, 1989, through February 1, 1993. Bonds that entered an extended maturity period from May 1, 1989, through February 1, 1993, had a guaranteed minimum investment yield of 6 percent per annum, compounded semiannually, during that extended maturity period.
