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.):\n[Book-entry par investment ÷ 100] × [CRV value for $100 bond].","path":["Title 31—Money and Finance: Treasury","Subtitle B—Regulations Relating to Money and Finance","CHAPTER II—FISCAL SERVICE, DEPARTMENT OF THE TREASURY","SUBCHAPTER A—BUREAU OF THE FISCAL SERVICE","PART 359—OFFERING OF UNITED STATES SAVINGS BONDS, SERIES I","Subpart C—Book-Entry Series I Savings Bonds"],"source_url":"https://www.ecfr.gov/api/versioner/v1/full/2026-08-25/title-31.xml","current_through":"2026-08-25","vintage":"","retrieved_at":"2026-08-27T02:25:25Z","sha256":"e0e859739ce425c6d95b2b63907b697fcd7e3a44b47117f6ca3a8dd0bfdc0db6","source_id":"us-cfr","stale":true,"prev":"us/31-cfr-359.54","next":"us/31-cfr-359.56"},"notice":"GroundRules: Original legal text.
