6. Capital Structure and the Pie • The value of a firm is defined to be the sum of the value of the firm’s debt and the firm’s equity. V =D + E • If the goal of the firm’s management is to make the firm as valuable as possible, then could the firm pick the debt-equity ratio that makes the pie as big as possible? S D E Value of the Firm Corporate Finance Lecture Note 1

7. MM Proposition I (No Taxes)Debt Policy is Irrelevant • MM Proposition I (No Taxes) • Assumption • Intuition • capital structure is irrelevant S E S E D B B D = Corporate Finance Lecture Note 1

8. Modigliani-Miller Proposition I (No Taxes) • The total value of the securities issued by a firm is independent of the firm’s choice of capital structure. • The firm’s value is determined by its real assets and growth opportunities, not by the types of securities it issues. *This is the very step Modigliani-Miller results, and it holds in an idealized world. Corporate Finance Lecture Note 1

9. Assumptions under Modigliani-Miller Proposition I • 1. Capital structure does not affect investment policy • 2. No taxes (corporate taxes, personal taxes, etc) • 3 Bankruptcy is costless • 4. Managers maximized shareholders’ (E) value, not total firm value (the Pie, E+D). • 5. Perfect and complete capital markets • 6. Symmetric information (No black box) Corporate Finance Lecture Note 1

10. Intuition • We can create a levered or (un)levered position by adjusting the trading in our own account. • This homemade leverage suggests that capital structure is irrelevant in determining the value of the firm:VL = VU Corporate Finance Lecture Note 1

11. Homemade Leverage: An Example Recession Expected Expansion EPS of Unlevered Firm $2.50 $5.00 $7.50 Earnings for 40 shares $100 $200 $300 Less interest on $800 (8%) $64 $64 $64 Net Profits $36 $136 $236 ROE (Net Profits / $1,200) 3.0% 11.3% 19.7% We are buying 40 shares of a $50 stock, using $800 in margin. We get the same ROE as if we bought into a levered firm. Our personal debt-equity ratio is: Corporate Finance Lecture Note 1

13. Homemade (Un)Leverage: An Example Recession Expected Expansion EPS of Levered Firm $1.50 $5.67 $9.83 Earnings for 24 shares $36 $136 $236 Plus interest on $800 (8%) $64 $64 $64 Net Profits $100 $200 $300 ROE (Net Profits / $2,000) 5% 10% 15% Buying 24 shares of an otherwise identical levered firm along with some of the firm’s debt gets us to the ROE of the unlevered firm. This is the fundamental insight of M&M Corporate Finance Lecture Note 1

15. In-Class Exercise • Ross, Westerfield, and Jaffe Question 1 (pp. 449) • Firm has a total market value of $150,000 under no debt. EBIT (Earnings before interest and taxes) is $14,000 under normal case and is 40% higher if in expansion and is 70% lower when it is recession. There are currently 2,500 shares outstanding. • 1. Calculate EPS (Earnings per share) • 2.Repeat 1 when the firms issues $60,000 to buyback the shares in the open market. Corporate Finance Lecture Note 1

17. Summary: MM Proposition I (No Taxes) • We can create a levered or unlevered position by adjusting the trading in our own account. • This homemade leverage suggests that capital structure is irrelevant in determining the value of the firm: VL = VU Corporate Finance Lecture Note 1

18. MM Proposition II (No Taxes) Corporate Finance Lecture Note 1

19. Roadmap • MM Proposition I (No Taxes) • Equity risk increases wit the level of debt • Proof • Economic Intuition Corporate Finance Lecture Note 1

20. Modigliani-Miller Proposition II (No Taxes) • We denote the expected returns on assets, debt and equity by RA, RD , and RE ,respectively. Then Where D and E are the market values of debt and equity and Corporate Finance Lecture Note 1

21. Modigliani-Miller Proposition II (No Taxes) • Proof: • Let total market value of the assets, debt, and equity as A, D, and E, respectively Corporate Finance Lecture Note 1

22. MM Proposition II (No Taxes) Cost of capital: R (%) RA RA RD RD Debt-to-equity Ratio Corporate Finance Lecture Note 1

23. MM Proposition II (No Taxes) • 1. Increasing the debt level does not affect the riskiness of the assets, but it does increase the riskiness of the equity • In the same firm, RD is always less than RE, This is because the debt has a higher priority and this is less risky. But the weighted sum of the returns of debt and equity is always a constant, and is equal to the return on assets, RA Corporate Finance Lecture Note 1

24. In-Class Exercise • Please evaluate the following argument: “ Equity is cheap because the firm does not have to pay investors any dividends if it does not want to.” Corporate Finance Lecture Note 1

25. In-Class Exercise: P/E ratio • Firm X has expected revenues (or EBIT) of $5 million per year. It has a capital structure with $10 million in risk-free debt paying 4% and 4 million shares which sell at $10/share. This implies that firm value is $50 million. • 1. What are the RA, RD , and RE, and EPS • 2. What is the P/E ratio? Corporate Finance Lecture Note 1

26. In-Class Exercise: P/E ratio • RA= $5 /(40+10)=10% • EPS=(5-10*0.04)/4=$1.15/share • P/E=10/1.15=8.7 Corporate Finance Lecture Note 1

27. Continued • The CEO decides to boost the P/E ratio in order to “increase shareholder value”. The firm issues 1 million new shares at $10/share and uses the proceeds to buy back all its debt. • What are the EPS and P/E ratio? • Can you evaluate the firms based on the P/E ratio and EPS? Corporate Finance Lecture Note 1

28. In-Class Exercise: P/E ratio • EPS=(5-)/5=$1/share • P/E=10/1=10 • In evaluating firms, we must focus on expected cash flows and risk, not P-E ratios and earnings per share Corporate Finance Lecture Note 1

29. In-Class Exercise: Share repurchase • The firm now repurchases 20 shares. • Can you evaluate the firms based on the P/E ratio and EPS? Corporate Finance Lecture Note 1
