a.A bond that has a $1000par value (face value) and a contract or coupon interest rate of 11.7%that is paid semiannually. The bond is currently selling for a price of $1122and will mature in 10years. The firm's tax rate is 34%.

b. If the firm's bonds are not frequently traded, how would you go about determining a cost of debt for this company?

c.A new common stock issue that paid a $1.76dividend last year. The par value of the stock is $15,and the firm's dividends per share have grown at a rate of 8.3%per year. This growth rate is expected to continue into the foreseeable future. The price of this stock is now $27.97.

d.A preferred stock paying a 9.8%dividend on a $124par value. The preferred shares are currently selling for $ 154.62.

e.A bond selling to yield 13.4%for the purchaser of the bond. The borrowing firm faces a tax rate of 34%.
