Pricing a coupon-paying bond Coupon bonds are generally issued with terms greater than 12 months. Examples include: Commonwealth government bonds semi-government bonds corporate long term securities (e.g. debentures). The coupons can be viewed as a series of zero-coupon bonds: one for each of the coupon payments and one at maturity.
Pricing a coupon-paying bond Price of a coupon-paying bond is: where c(t) is the coupon payment in period t y(t) is the yield at time (t) FV is the face value paid at maturity (T). The price of a coupon-paying bond can also be expressed as an annuity: where c is the coupon payment in period t y is the yield FV is the face value (principle) paid at maturity (T).

Pricing a coupon-paying bond Example Given a yield of 3.6% p.a. on a 2-year 4.5% p.a. bond with principal of \$100 000, price can be calculated as: The price of a coupon paying bond can exceed the face value of the bond (i.e bond is selling at a premium to FV). Consider a bond with a coupon rate of 4.5% p.a., term of 2yrs and a face value of \$100. If y = 3.6% p.a., P = \$101.722 per \$100. (i.e. trades at a premium to FV) If y = 5% p.a., P = \$99.060 per \$100. (i.e. trades at a discount to FV)
Pricing a coupon-paying bond Where the coupon rate is less than the yield, the bond price is less than the principle, and vice versa. To summarise: Premium: c > y implies P > FV (i.e. coupon rate is greater than market yield) Par: c = y implies P = FV (i.e. coupon rate is equal to market yield) Discount: c < y implies P < FV. (i.e. coupon rate is less than market yield)

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
