HP and Dell are companies in the exact same business. They both used to have the same capital structure with a debt-to-equity ratio of 1:20. Recently, however, Dell hired many investment bankers and consultants at great expense and decided to change its debt-to-equity ratio to 1:5. HP figures that they will copy Dell and their expensive advice, and move their debt-to-equity ratio to 1:5 as well. HP doesnt want to pay for the bankers and consultants that Dell used, though, and they rely on you to help them understand the transition. What is HPs new weighted average cost of capital? Assume the following: HP used to have a cost of debt of 3% and a cost of equity of 20%. After the change, HP will have a cost of debt of 5%. The change in D/E is expected to be permanent. Further, they have a tax rate of 30%. Please show all your steps clearly!
