Problem:
Shearson PLC's stock sells for $42 per share. The company wants to sell some 20-year, annual interest, $1,000 par value bonds. Each bond will have attached 75 warrants, each exercisable into one share of stock at an exercise price of $47. Shearson's straight bonds yield 10 percent. The warrants will have a market value of $2 each when the stock sells for $42. What coupon interest rate must the company set on the bonds-with-warrants if the bonds are to sell at par?
