Stock price $32
Years till maturity 10
Conversion premium $70
Coupon rate 11%
a. If the price of Tulsa Drilling Company common stock rises to $42 on this date next year, what would your
rate of return be if you bought a convertible bond today and sold it in one year? Assume that on this date next
year, the conversion premium has shrunk from $70 to $20.
Current market price of convertible bond $1,350
Price of convertible next year $1,700
Annual return 34.07%
b. Assume the yield on similar nonconvertible bonds has fallen to 8 percent at the time of sale. What would
the pure bond value be at that point? (Use semiannual analysis.)
Yield at time of sale 8%
Years remaining 9
Pure bond value $1,190
Would the pure bond value have a significant effect on valuation then?
Because the pure bond value of $1,190.24 is still well below the conversion value of $1,680 and the market
value of $1,700, it would not have a significant effect on valuation. The stock price is the major factor determining the
convertible bond price.
