Bonds
Terminology
?Bond - Security that obligates the issuer to
make specified payments to the bondholder.
?Coupon - The interest payments made to the
bondholder.
?Face Value (Par Value or Maturity Value) - Payment
at the maturity of the bond.
?Coupon Rate - Annual interest payment,as a
percentage of face value.

Bonds
WARNING
The coupon rate IS NOT the discount rate
used in the Present Value calculations.
The coupon rate merely tells us what cash flow the
bond will produce,
Since the coupon rate is listed as a %,this
misconception is quite common.

Bond Pricing
The price of a bond is the Present Value of
all cash flows generated by the bond (i.e,
coupons and face value) discounted at the
required rate of return.

Q,How did the calculation change,given semi-
annual coupons versus annual coupon payments?
Time Periods
Paying coupons twice a
year,instead of once
doubles the total number of
cash flows to be discounted
in the PV formula.
Discount Rate
Since the time periods are
now half years,the
discount rate is also
changed from the annual
rate to the half year rate.

Bond Yields
?Current Yield - Annual coupon payments
divided by bond price.
?Yield To Maturity - Interest rate for which
the present value of the bond’s payments
equal the price.

Bond Yields
Calculating Yield to Maturity (YTM=r)
If you are given the price of a bond (PV)
and the coupon rate,the yield to maturity
can be found by solving for r.

WARNING
Calculating YTM by hand can be very
tedious,
It is highly recommended that you learn to
use the,IRR” or,YTM” or,i” functions on
a financial calculator,
