31 C.F.R. § 351.70 How are redemption values calculated for book-entry Series EE savings bonds?
Title 31 - Money and Finance: Treasury
We base current redemption values (CRV) for book-entry Series EE savings bonds on the definitive savings bond CRV. We use the CRV for a $100 principal amount as calculated in §351.16 to calculate a CRV prorated to the book-entry principal investment amount for the corresponding issue and redemption dates. Calculated book-entry CRV will be rounded to the nearest one cent.3 3 Example: Calculated value of $25.044 rounds to $25.04; calculated value of $25.045 rounds to $25.05. [Book-entry principal investment ÷ $100] × [CRV value for $100 principal amount].
