10–16
▪ Interest expense each period is generally comparable in amount. However, when the
amounts are materially different, the effective-interest method is required under
generally accepted accounting principles (GAAP).
Amortizing Bond Discount
▪ To illustrate, assume that Candlestick Inc. issues $100,000 of 10%, 5-year bonds on
January 1, 2012, with interest payable each January 1. The bonds sell for $98,000,
which results in bond discount of $2,000 ($100,000 – $98,000) and an effective-
interest rate of 10.53%. For the first period, the computations of bond interest
expense and the bond discount amortization are as follows:
▪ The entry to record the accrual of interest and amortization of bond discount by
Candlestick Inc. on December 31, is:
Dec. 31 Interest Expense ………………………………………….. 10,319
▪ For the second interest period, bond interest expense will be $10,353 ($98,319 x
10.53%) and the discount amortization will be $353. At December 31, the following
adjusting entry is made:
Dec. 31 Interest Expense ………………………………………….. 10,353
Work through Illustration 10B-2 Bond discount amortization schedule to demonstrate the
calculations for the effective-interest method of amortization of the bond discount.
Amortizing Bond Premium
▪ The amortization of bond premium by the effective-interest method is similar to the
procedures described for bond discount.
▪ As an example, assume that Candlestick Inc. issues $100,000, 10%, 5-year bonds on
January 1, with interest payable on January 1. In this case, the bonds sell for $102,000,
