359.55—How are redemption values calculated for book-entry Series I savings bonds?

We base current redemption values (CRV) for book-entry Series I savings bonds on the definitive savings bonds CRV. To calculate the book-entry values, we use the CRV for the $100 denomination Series I savings bonds and calculate a CRV prorated to the book-entry par investment amount for the corresponding issue and redemption dates. Calculated book-entry CRV will be rounded to the nearest one cent. 4 The formula is as follows (Examples of the calculation are given in appendix A to part 359.):
