BOND VALUATION
All bonds have the following characteristics:
1. A maturity date- typically 20-25 years.
2. A coupon rate- the rate of interest that the issuing company pays to the holder.
3. A face value- usually $1000 or $5000.

BOND VALUATION
The value of a bond is the sum of the present value of the annual interest payments plus the present value of the face value;

BOND VALUATION
EXAMPLE
Find the value of a 20 year, 10%, $1000 face value bond.The interest payment is given by: .10 x $1000 = $100/year
THE FORMULA IS:
PV =
20
120)1(
1000$
)1(
100$
NN rr
PV = $100(6.145) + $1000(.386) = $614.50 + $386 = $1000

BOND THEOREMS
In this section we will look at the relationship between changes in bond prices and changes in term to maturity, coupon rate, and discount rates (market yields).

Change in Bond Prices
• Price of 7 1/4 bond fell by $3.75 or .42%
• Price of 10 3/8 bond fell by $5.00 or .48%
• When market yields fall unexpectedly, the prices of financial assets rise and vice-versa

Theorem II
Holding coupon rate constant, for a given change in market yields, percentage changes in bond prices are greater the longer the term to maturity.

Theorem III
The percentage price changes described in Theorem II increase at a decreasing rate as N increases.
- Slopes are percentage changes.

Theorem IVHolding N constant and starting from same market yield, equal yield changes up or down do not result in equal percentage price changes. A decrease in yield increases prices more than an equal increase in yield decreases prices. Price changes are asymmetric with respect to changes in yield.

Theorem V
Holding N constant and starting from the same yield,the greater the coupon rate, the smaller the
percentage change in price for a given change in yield.
