5. PrivateEq is a PE fund that is considering buying out QuickGas, a chain of gas stations.To get an estimate of QuickGass cost of capital, it estimates the equity beta of a portfolio of publicly-traded gas station chains, which it finds to be 1.3. Gas station chains have significant leverage: the debt-to-equity ratio of the portfolio is 1. Moreover, the beta of this debt is 0.3. The risk-free rate is 3% and the market risk premium is8%. The corporate tax rate is 35%.(a) Assuming that the gas station chains maintain a constantD/E ratio, what is their unlevered beta?(b) Suppose PrivateEq plans to run QuickGas with a constantD/E ratio of 3/2.Assuming QuickGass debt beta will increase to 0.4, what will QuickGass WACC be?(c) Suppose PrivateEq instead plans to maintain a fixed, perpetual level of debt onQuickGass balance sheet with the level of debt set so that initially the debt-equity ratio isD0/E0= 3/2 (debt will then remain constant even as the equity value fluctuates). Under this scenario, what will be QuickGass WACC?
