25. Masters Corp. issues two bonds with 20-year maturities. Both bonds are callable at $1,050. The first bond is issued at a deep discount with a coupon rate of 4% and a price of $580 to yield 8.4%. The second bond is issued at par value with a coupon rate of 8¾%.

b. If you expect rates to fall substantially in the next 2 years, which bond would you prefer to hold?

c. In what sense does the discount bond offer “implicit call protection”?
