Coupon payment = coupon rate *nominal value
E.g. coupon rate = 5%; nominalvalue = Rs1000
Coupon = 5%*1000 = Rs50

Example
The market price of a zero coupon bond is
equal to Rs857.34; it has a maturity of 2
years and pays a nominal of Rs1000.
Determine the annual interest rate on the
bond.
Assume annual interest rate = r
857.34 (1 + r) 2 = 1000
r = (1000/ 857.34) 1 = 7.99 = 8%

Example
Market price= 986.51
Assume annual interest rate/ discount rate = k
Market price= 986.51= 50/ (1 + k) + 50/ (1 + k) 2 + 1050/ (1 + k) 3
k = 5.5%

Example
Choose a bond:
- Company Bond selling at Rs900; offers acoupon rate of 10%, a nominal of Rs1000
and has maturity of 5 years- Government Bond selling at Rs900; offers
a coupon rate of 10%, a nominal ofRs1000 and has maturity of 5 years

Financial Theory 11
Intrinsic value of bond (estimated
by investors/financial analysts) =
C/ (1 + k) + C/ (1 + k) 2 +
C/(1 + k) 3+ + C/ (1 + k) T
+ N/ (1 + k) T
C = coupon payment; N = nominalvalue; k = required rate of return;
T = maturity date

Current market price of bond
(available from bond market)= C/ (1 + YTM) + C/ (1 +
YTM) 2 + C/ (1 + YTM) 3 + +
C/ (1 + YTM) T + N/ (1 + YTM) T
YTM : Yield to maturity

Financial Theory 19
Example:
A bond has the followingcharacteristics:
Coupon rate 5%, nominal value
Rs1000 and maturity 2 years.
If the market price of the bond is
equal to Rs960, calculate theyield to maturity of the bond.

20/30
Financial Theory 20
960 = 50/ (1 + YTM) + 50/ (1 +
YTM) 2 + 1000/ (1 + YTM) 2
Multiply both sides by (1 + YTM) 2and simplify:
960 (1 + YTM) 2 - 50 (1 + YTM) 1050 = 0

Financial Theory 21
Assume (1 + YTM) = A
960 A 2 50 A 1050 = 0
Use quadratic equation formula tosolve
YTM = 7.2191%

Fractional period =
Number of(days/months)
between purchase date and nextcoupon payment date divided by
total number of(days/ months)over coupon period
E.g. 01/ 09/ 08 to 01/ 05/ 09 = 8months
Fractional period = 8/ 12
