The stock is currently selling for $15.25 per share, and its noncallable $1,000 par value, 20-year, 7.25% bonds with semiannual payments are selling for $875.00. The beta is 1.25, the yield on a 6-month Treasury bill is 3.50%, and the yield on a 20-year Treasury bond is 5.50%. The required return on the stock market (i.e., Rm)is 11.50%. The firm's tax rate is 40%.

1) What is the best estimate of the after-tax cost of debt (%)? i.e, (1-t)*kd?

2) Based on the CAPM, what is the firm's cost of equity (%) ? i.e., ke?

3) Calculate the weights of market value of debt and market value of equity for use in calculating the WACC based in market values? i.e., Wd (%) and We (%)

4) Calculate ABC's WACC (%) based on your answers to 1), 2), and 3)

Show all of your calculations with appropriate explanation.
