240 Chapter 12 Long-Term Liabilities: Bonds and Notes
LECTURE AID—Amortizing a Bond Discount Using the Straight-Line
Method
The calculation for amortization of bond discounts and premiums is covered in Appendix 1 of this
chapter. If the instructor chooses not to require students to calculate bond discounts and premiums, the
amounts can be provided with an explanation to complete the journal entries below. Refer to the previous
Demonstration Problem in which the $1 million, five-year, 10 percent bond that paid interest
semiannually was sold for $926,405 to yield the market interest rate of 12 percent. In the case of that
bond, the following statements are true:
1. The investor loans the company $926,405 by buying the bond.
3. Therefore, the investor gets $73,595 more at maturity than he or she paid for the bonds. The $73,595
4. Because the $73,595 discount is really just extra interest, it must be recorded as interest expense.
This interest must be spread across the five-year term of the bond. The process of recognizing a
portion of the discount as interest each time an interest payment is made to the bondholder is called
amortizing the discount.
Straight-line amortization of a bond discount is similar to straight-line depreciation. The discount is
amortized evenly over the bond’s life. The bond mentioned previously has a life of five years or a total of
The journal entry to record the interest payment and discount amortization is:
Interest Expense…………….……. 57,359.50
Discount on Bonds Payable 7,359.50
Cash ($1,000,000 5%)… 50,000.00
The process for straight-line amortizing the premium for bonds sold at a premium is to reduce the interest
expense each payment period. If we use the data from the Demonstration Problem above for bonds sold at
