2. Joan also had read about “zero-coupon” bonds, which are bonds that pay no interest. Therefore, they are offered at a substantial discount from par value, since the investor’s entire return is the difference between the discounted offering price and the par value. In particular, Joan had read that one company had issued eight-year, zero-coupon bonds at a price of $327 per $1,000 par value. Joan wanted to discuss the following with the accounting professor. (a) Was the yield on these bonds 15 percent, as Joan had calculated? (b) Assuming that bond discount amortization is tax deductible by the issuing corporation, that the issuer has a 40 percent income tax rate, and that for tax purposes a straight-line amortization of original discount is permissible, what is the effective or “true” after-tax interest rate to the issuer of this bond? And (c) if, instead of issuing these zero-coupon bonds, the company had issued 15 percent coupon bonds with issue proceeds of $1,000 per bond (i.e.,par value), what would the issuer’s effective after-tax interest rate have been on these alternative bonds
