Bond Characteristics
A long-term debt instrument in which a
borrower agrees to make payments of
principal and interest, on specific dates, to the
holders of the bond.
Par value – face amount of the bond, which is paid at maturity
Coupon interest rate – stated interest rate (generally fixed)
paid by the issuer. (Floating Rate Bond vs. Zero Coupon Bond)
Maturity date – years until the bond must be repaid.
Yield to maturity - rate of return earned on
a bond held until maturity (also called the “promised yield”).

What is the opportunity cost of debt capital?
The discount rate (k ) is the
opportunity cost of debt capital, and is
the rate that could be earned on
alternative investments of equal risk.
k = k* + IP + MRP + DRP + LP

Prices and Yields (required rates of
return) have an inverse relationship.
When yields get very high the value of the
bond will be very low.
When yields approach zero, the value of
the bond approaches the sum of the
cash flows.

Find the current yield for a 10-year, 9% annual coupon bond that sells for $887, and has a face value of $1,000.
Current yield = $90 / $887 = 0.1015 = 10.15%

Bond values over time
At maturity, the value of any bond must equal its par value.
If kd remains constant:
The value of a premium bond would decrease over time, until it reached $1,000.
The value of a discount bond would increase over time, until it reached $1,000.
A value of a par bond stays at $1,000.

Expectations Theory
Observed long-term rate is a function of today’s short-term rate and expected future short-term rates.
Forward rates that are calculated from the yield on long-term securities are market consensus expected future short-term rates.

Long-term bonds are riskier.
Investors will demand a premium for the risk
associated with long-term bonds.
The yield curve has an upward bias built into the
long-term rates because of the risk premium.
Forward rates contain a liquidity premium and
are not equal to expected future short-term rates.

Short- and long-term bonds are traded in distinct markets.
Trading in the distinct segments determines the various rates.
