The beta for the stock is 1.35, and the pretax cost of debt is 6.80%. The Treasury bond rate is 6%. Assume that the firm is considering a massive increase in leverage to a 70% debt ratio, at which level the bond rating will(with a pretax interest rate of 16%).

b. Assuming that all debt gets refinanced at the new market interest rate, what would your interest ex- penses be at 70% debt? Would you be able to get the entire tax benefit? Why or why not?

c. Estimate the beta of the stock at 70% debt, using the conventional levered beta calculation. d. Reestimate the beta, on the assumption that C-rated debt has a beta of 0.60. Which one would you use in your cost of capital calculation?

d. Estimate the cost of capital at 70% debt.

e. What will happen to firm value if Intel moves to a 70% debt ratio? (with no growth)
