[Exercise 3]
On January 1, 2006, Company A issues long-terms bonds which are due on
January 1, 2011. Interest is paid semiannually on January 1 and
July 1 each year. Face amount of bonds is $500,000 with stated
interest rate (coupon rate) of 10%. At the time of issuance,
market interest rate is 12%.
As explained in Exercise 1, the price of bonds is $463,202, and
bonds will be sold at $36,798 discount from the face amount of
$500,000.
Calculate the amortization of discount on bonds using
effective
interest method. |

Interest payment each semiannual period
= $500,000 x 5%
= $25,000
(Coupon rate for a semiannual period = 10% / 2 = 5%.)
Effective interest rate =
Market interest rate = 12%
Effective interest rate for a semiannual period = 12% / 2 = 6%
Interest expense
= Present value of bonds at the beginning of the period
x Effective interest rate for
the period
[1/1/2006 - 7/1/2006] --> $463,202 x 6% =
$27,792
[7/1/2006 - 1/1/2007] --> $465,994 x 6% =
$27,960
Amortization of discount on bonds
= Interest expense - Interest paid
[1/1/2006 - 7/1/2006] --> $27,792 - $25,000
= $2,792
[7/1/2006 - 1/1/2007] --> $27,960 - $25,000
= $2,960
Ending present value of bonds
= Beginning present value of bonds
+ Amortization of
discount on bonds
[1/1/2006 - 7/1/2006] --> $463,202 + $2,792
= $465,994
[7/1/2006 - 1/1/2007] --> $465,994 + $2,960
= $468,954

[Exercise 4]
On January 1, 2006, Company A issues long-terms bonds which are due on
January 1, 2011. Interest is paid semiannually on January 1 and
July 1 each year. Face amount of bonds is $500,000 with stated
interest rate (coupon rate) of 10%. At the time of issuance,
market interest rate is 8%.
As explained in Exercise 2, the price of bonds is $540,573, and
bonds will be sold at $40,573 premium over the face amount of
$500,000.
Calculate the amortization of premium on bonds using
effective
interest method. |
