Consider issues about when a firm should consider using a single hurtle rate versus using divisional rates in a generalized sense. I would like you to make an effort to calculate the WACC for Marriott overall which requires following a couple of steps: • First, we need to unlever Marriott's Equity Beta with the actual debt ratio and relever the unlevered asset beta with the target debt ratio. • Second, calculate the cost of equity using CAPM. • Third estimate the firm's cost of debt using the yield data in the case. • Finally, estimate their WACC. • After that is done, go through the same steps to calculate the WACC for the lodging and restaurant divisions using their respective comparable firms to estimate an average asset beta. • Since there are no comparable firms for the contract services, consider how you might estimate their WACC using what you know about the other two divisions.
