Extinguishment of Debt (E13.12) On January 2, 2020, Banno Corporation issued $1,500,000 of 10% bonds at 97 due December 31,2029 . Interest on the bonds is payable annually each December 31 . The discount on the bonds is also being amortized on a straight-line basis over the 10 years. (Straight-line is not materially different in effect from the preferable "interest method.") The bonds are callable at 101 (i.e., at 101% of face amount), and on January 2, 2025, Banno called $900,000 face amount of the bonds and redeemed them.
