F has 200,000 shares outstanding with a market value of $30 each and no debt. F is subject to a corporate tax rate TC = 30% and the beta of unlevered equity 0 is 0.8. Risk-free rate is 3% and expected return of the market portfolio is 8%. We ignore bankruptcy costs in this exercise. F considers the following alternative operations

a. The beta of debt B is 0.1 after operation 1. Compute the S of levered equity after operation 1 and after operation 2.

b. Operation 3: F buys portfolio of stocks worth $1,000,000 (at market value). This purchase is financed by issuing risk-free debt for the same amount. Following the operation, F's beta of levered equity increases to 1. Compute the systematic risk PF of the portfolio bought by F. Hint: What is the beta of a portfolio of assets?
