### Understanding capital structure

1. 1. Understanding Capital Structure<br />www.HelpWithAssignment.com<br />
2. 2. A company can obtain long-term financing in the form of equity, debt or a combination of both. <br />Capital structure is the proportion of debt and preference and equity shares on a firm’s balance sheet.<br />Capital Structure<br />www.HelpWithAssignment.com<br />
3. 3. Optimal Capital structure is the capital is the capital structure at which the weighted average cost of capital is minimum and thereby maximum value of the firm.<br />Capital Structure<br />www.HelpWithAssignment.com<br />
4. 4. The relative proportions of debt, equity and other securities that a firm has outstanding constitute its capital structure. <br />When corporations raise funds from outside investors, they must choose which type of security issue. <br />Capital Structure<br />www.HelpWithAssignment.com<br />
5. 5. The most common choices are financing through equity alone and financing through a combination of debt and equity. <br />So V = B + S = D + E<br />Capital Structure<br />www.HelpWithAssignment.com<br />

7. 7. Shareholders are interested in maximizing the value of the firm’s shares. <br />A key question is: What is the ratio of debt to equity, if any, that maximizes the shareholder’s value? <br />Capital Structure<br />www.HelpWithAssignment.com<br />
8. 8. As it turns out, changes in capital structure benefit shareholders if and only if the value of the firm increases. <br />So we concern ourselves with the question of which proportion of debt versus equity maximizes the overall value of the firm.<br />Capital Structure<br />www.HelpWithAssignment.com<br />
9. 9. We assume perfect capital markets in the following analysis:<br />Perfect competition<br />Equal access to information<br />No transaction costs<br />No taxes (later we drop this assumption) <br />We also assume that the individual can borrow at the same rate as the firm.<br />Capital Structure<br />www.HelpWithAssignment.com<br />
10. 10. We will compare a firm whose capital structure is all equity, with a firm that is identical, except that it has some debt in its capital structure.<br />Example: Capital Structure<br />www.HelpWithAssignment.com<br />
11. 11. Suppose a firm has 1000 shares, a share price of \$10, a market value of \$10,000, and operating income as described in the table below. <br />This income is a perpetuity, and all earnings are paid out as a dividend to investors. Expected income is \$1500 and expected return is 15%.<br />Example: Capital Structure<br />www.HelpWithAssignment.com<br />
12. 12. Example: Capital Structure<br />www.HelpWithAssignment.com<br />
13. 13. Suppose the firm borrows \$5,000 at 10% rate of interest and buys back 500 of its shares to create the following new situation: # shares 500, B = \$5000, S = \$5000, shares value: \$10, annual interest: \$500<br />Example: Capital Structure<br />www.HelpWithAssignment.com<br />
14. 14. Example: Capital Structure<br />www.HelpWithAssignment.com<br />
15. 15. Argument that value has increased: If operating income is greater than \$1,000 then the expected Return On Equity increases. <br />Since we expect operating income of \$1,500, leverage must have added value. Shareholders expect 20% ROE with leverage.<br />Example: Capital Structure<br />www.HelpWithAssignment.com<br />
16. 16. Counter-argument: Suppose an investor takes \$10 of his/her own money and borrows \$10 at 10% interest and invests the \$20 to buy 2 shares of the unlevered firm.<br />Example: Capital Structure<br />www.HelpWithAssignment.com<br />
17. 17. Example: Capital Structure<br />www.HelpWithAssignment.com<br />
18. 18. Note: Investor gets the same result from borrowing personally as he/she gets from investing in the leveraged firm. <br />Therefore, the firm is not doing anything by leveraging that the investor could not do on his/her own. <br />This implies VL = VU. This is the famous Modigliani-Miller Proposition I.<br />Example: Capital Structure<br />www.HelpWithAssignment.com<br />
19. 19. So leverage increases the expected earnings per share, but not the share price. How can that be?<br />Example: Capital Structure<br />www.HelpWithAssignment.com<br />
20. 20. Leverage also increases the riskiness of the earnings. We must discount those higher expected earnings at a higher discount rate.<br />All equity: 1.50/.15 = \$10<br />Leveraged: 2.00/.20 = \$10<br />Recall: The value of a firm = the PV of the future cash flows. <br />Example: Capital Structure<br />www.HelpWithAssignment.com<br />
21. 21. If the firm is all equity financed, then VU = C1/(1+r0) + C2/(1+r0)2 + … where r0 is the cost of capital of an all equity financed firm. <br />If there is some debt in the capital structure, the cost of capital is given by: <br />Example: Capital Structure<br />www.HelpWithAssignment.com<br />
22. 22. r = [B/(B+S)]rB + [S/(B+S)]rS where rS is the cost of equity capital of the now leveraged firm.<br />and VL = C1/(1+r) + C2/(1+r)2 + ...<br />Example: Capital Structure<br />www.HelpWithAssignment.com<br />
23. 23. Since the value of the company doesn’t change with leverage, VL = VU, and so r must equal r0 – that is, r must be constant as debt is added to the capital structure (remember here we are assuming no taxes etc.). <br />Example: Capital Structure<br />www.HelpWithAssignment.com<br />
24. 24. The idea is that as “expensive” equity is replaced with “cheap” debt, the risk to equity increases, as a result of the increased leverage, and so rS increases. <br />The increase in rS just balances against the increased fraction of cheaper debt, so that r stays constant.<br />Example: Capital Structure<br />www.HelpWithAssignment.com<br />
25. 25. r0 = cost of capital for the all equity firm = ra = required/expected return on the assets – reflects business risk – not financial leverage. If we solve:<br />r0 = [B/(B+S)]rB + [S/(B+S)]rS for rS, we get rS = r0 +[B/S](r0 – rB)<br />Example: Capital Structure<br />www.HelpWithAssignment.com<br />
26. 26. This is Modigliani-Miller Proposition II.<br />In our example above, ra = 1500/10,000 = 15%. If B = S = 5000, then:<br />rS = 15% + [5000/5000](15% - 10%) = 20%<br />Initially the firm was all equity, had 1,000 shares at \$10/share and equity worth \$10,000<br />V = 1500/.15 = (CF/rS) = \$10,000<br />Example: Capital Structure<br />www.HelpWithAssignment.com<br />
27. 27. With \$5,000 debt at 10% and \$5,000 equity, now rS = 20%, up from 15% and:<br />V = 500/.10 + 1000/.20 = interest payment/rB + CF/rS = 5,000 + 5,000 = 10,000<br />Example: Capital Structure<br />www.HelpWithAssignment.com<br />
28. 28. Essentially, we split a single cash flow of 1500/year, discounted at 15% into 2 cash flows of 500 and 1000, the former discounted at 10% and the latter discounted at 20%<br />Example: Capital Structure<br />www.HelpWithAssignment.com<br />
