You are a financial manager at Uber and want to estimate the beta before Uber goes public. Suppose you find a comparable company that has been publicly traded for enough years to have measurable market beta. The comparable company has a beta of 1.5, a debt of $15 billion, equity of $50 billion and a tax rate of 34 percent. Suppose that Uber has a debt of $10 billion and Uber's equity is estimated to be $50 billion. Uber pays a 30 percent tax rate. The expected return for the market portfolio is 15 percent and the risk-free rate is 6 percent.
