You are an investment banker trying to value Dell, a private company. You have forecasted Dells free cash flows, but need to compute its WACC in order to value the firm. Unfortunately Dell is private and so it does not have stock data, so you cannot use CAPM to find its cost of equity. You know the following: Dell has debt of $600 at a cost of 5%; further, Dell recently raised money from equity investors, valuing the equity at $800. HP is in the same exact business as Dell, but it is public so you can see its cost of equity. HP is financed with a constant debt-to-equity ratio of 3/10, has a cost of debt of 3%, a cost of equity of 22%, and a tax rate of 30%. Find the unlevered cost of capital for Dell and HP. Assume that HPs debt-to-equity ratio will stay constant forever.
