[Code of Federal Regulations] [Title 31, Volume 2] [Revised as of July 1, 2005] From the U.S. Government Printing Office via GPO Access [CITE: 31CFR359.55] [Page 456] TITLE 31--MONEY AND FINANCE: TREASURY CHAPTER II--FISCAL SERVICE, DEPARTMENT OF THE TREASURY PART 359_OFFERING OF UNITED STATES SAVINGS BONDS, SERIES I--Table of Contents Subpart C_Book-Entry Series I Savings Bonds Sec. 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.\5\ The formula is as follows (Examples of the calculation are given in Appendix A to part 359.): --------------------------------------------------------------------------- \5\ Example: Calculated value of $25.044 rounds to $25.04; calculated value of $25.045 rounds to $25.05. [Book-entry par investment / 100] x [CRV value for $100 bond].
