An example might be a 10% coupon rate An example might be a 10% coupon rate $1000 par value bond selling for $950.$1000 par value bond selling for $950.
The current yield would be:The current yield would be:
$100 / $950 = 10.53%$100 / $950 = 10.53%

Calculating Bond Prices and YTM Method 1 - using Tables
Present Value of Coupon Payments (Ct) Present value of Maturity Value (Pn) (from Table 12-1 or Appendix D) (from Table 12-2 or Appendix C)
n = 20, i = 12 % n = 20, i = 12%
$100 x 7.469 = $746.90 $1,000 x 0.104 = $104.00
Present value of coupon payments = $746.90 Present value of maturity value = $104.00 Value of bond = $850.90

Yield to CallYield to Call
Call dateCall date Yield to call value is determined by: Yield to call value is determined by:
• the coupon rate, the coupon rate, • the length of time to the call date, the length of time to the call date,
and and • the market price.the market price.

Yield to Call ExampleYield to Call Example
Assume a 20-year bond was initially issued Assume a 20-year bond was initially issued at 11.5% interest rate, and after two years, at 11.5% interest rate, and after two years, rates have dropped. Let us assume the bond rates have dropped. Let us assume the bond is currently selling for $1,180, and the yield is currently selling for $1,180, and the yield to maturity on the bond is 9.48%. However, to maturity on the bond is 9.48%. However, the investor who purchases the bond for the investor who purchases the bond for $1,180 may not be able to hold the bond for $1,180 may not be able to hold the bond for the remaining 18 years the remaining 18 years becausebecause the issue the issue can be called. Under theses circumstances, can be called. Under theses circumstances, yield to maturity may not be the appropriate yield to maturity may not be the appropriate measure of return over the expected measure of return over the expected holding period. holding period.

Yield to Call Calculation – Example cont.Yield to Call Calculation – Example cont.
In the present case, we assume the bond In the present case, we assume the bond can be called at $1,090 five years after can be called at $1,090 five years after issue. Thus, the investor who buys the issue. Thus, the investor who buys the bond two years after issue can have his bond two years after issue can have his bond called back after three more years at bond called back after three more years at $1,090. To compute yield to call, we $1,090. To compute yield to call, we determine the approximate interest rate determine the approximate interest rate that will equate a $1,180 investment today that will equate a $1,180 investment today with $115 (11.5%) per year for the next with $115 (11.5%) per year for the next three years plus a payoff or call price value three years plus a payoff or call price value of $1,090 at the end of three years.of $1,090 at the end of three years.

Investment Strategy: Interest-Rate Considerations (7 rules) (7 rules)
Bond Pricing Rules
• 1. Bond prices and interest rates are
inversely related.
• 2. Prices of long-term bonds are more
sensitive to a change in yields to maturity
than short-term bonds.
• 3. Bond price sensitivity increases at a
decreasing rate as maturity increases.
