Zheng Enterprises, a multinational drug company specializing in Chinese medicines, issued $100 million of 15 percent coupon rate bonds in January 2011. The bonds had an initial maturity of 30 years. The bonds were sold at par and were callable in five years at 110 (that is, 110 percent of par value). It is now January 2016, and interest rates have declined such that bonds of equivalent remaining maturity now sell to yield 11 percent. How much would you be willing to pay for one of these bonds today? Why?
