For each firm, calculate their required return on levered equity. Does the required return on levered equity for firm 1 differ from the required return on levered equity for firm 2 ? Explain your answer. Detail all calculations that you use d. Consider Table 1. Now suppose that personal taxes exist. The personal tax rate on equity income is 10% and the personal tax rate on debt income is 20%. Show how the value of firm 2 changes given corporate and personal taxes.
