The accounting for bonds involves a number of transactions over the life of a bond. The accounting for these transactions from the perspective of the issuer is noted below. Bond Issuance. When a bond is issued at its face amount, the issuer receives cash from the buyers of the bonds and records a liability for the bonds issued. The liability is recorded because the issuer is now liable to pay back the bond.
May 12, 2019· Convexity and Risk. Convexity is a better measure of interest rate risk, in relation to duration, because the concept of duration assumes that interest rates and bond prices have a linear relationship. Duration can be a good measure of how bond prices may be affected due to small and sudden fluctuations in interest rates.
