Copyright © 2002 by Harcourt Inc.All rights reserved. Who are Modigliani and Miller (MM)? They published theoretical papers that changed the way people thought about financial leverage. They won Nobel prizes in economics because of their work. MMs papers were published in 1958 and Miller had a separate paper in The papers differed in their assumptions about taxes.

Copyright © 2002 by Harcourt Inc.All rights reserved. What assumptions underlie the MM and Miller models? Firms can be grouped into homogeneous classes based on business risk. Investors have identical expectations about firms future earnings. There are no transactions costs. (More...)

Copyright © 2002 by Harcourt Inc.All rights reserved. All debt is riskless, and both individuals and corporations can borrow unlimited amounts of money at the risk-free rate. All cash flows are perpetuities. This implies perpetual debt is issued, firms have zero growth, and expected EBIT is constant over time. (More...)

Copyright © 2002 by Harcourt Inc.All rights reserved. MMs first paper (1958) assumed zero taxes. Later papers added taxes. No agency or financial distress costs. These assumptions were necessary for MM to prove their propositions on the basis of investor arbitrage.

Copyright © 2002 by Harcourt Inc.All rights reserved. Firms U and L are in same risk class. EBIT U,L = $500,000. Firm U has no debt; k sU = 14%. Firm L has $1,000,000 debt at k d = 8%. The basic MM assumptions hold. There are no corporate or personal taxes. Given the following data, find V, S, k s, and WACC for Firms U and L.

Copyright © 2002 by Harcourt Inc.All rights reserved. Find V, S, k s, and WACC for Firms U and L assuming a 40% corporate tax rate. With corporate taxes added, the MM propositions become: Proposition I: V L = V U + TD. Proposition II: k sL = k sU + (k sU - k d )(1 - T)(D/S).

Copyright © 2002 by Harcourt Inc.All rights reserved. Notes About the New Propositions 1.When corporate taxes are added, V L V U. V L increases as debt is added to the capital structure, and the greater the debt usage, the higher the value of the firm. 2.k sL increases with leverage at a slower rate when corporate taxes are considered.

Copyright © 2002 by Harcourt Inc.All rights reserved. Assume investors have the following tax rates: T d = 30% and T s = 12%. What is the gain from leverage according to the Miller model? Millers Proposition I: V L = V U + [ 1 - ] D. T c = corporate tax rate. T d = personal tax rate on debt income. T s = personal tax rate on stock income. (1 - T c )(1 - T s ) (1 - T d )

Copyright © 2002 by Harcourt Inc.All rights reserved. T c = 40%, T d = 30%, and T s = 12%. V L = V U + [ 1 - ] D = V U + ( )D = V U D. Value rises with debt; each $100 increase in debt raises Ls value by $25. ( )( ) ( )

Copyright © 2002 by Harcourt Inc.All rights reserved. How does this gain compare to the gain in the MM model with corporate taxes? If only corporate taxes, then V L = V U + T c D = V U D. Here $100 of debt raises value by $40. Thus, personal taxes lowers the gain from leverage, but the net effect depends on tax rates. (More...)

Copyright © 2002 by Harcourt Inc.All rights reserved. If T s declines, while T c and T d remain constant, the slope coefficient (which shows the benefit of debt) is decreased. A company with a low payout ratio gets lower benefits under the Miller model than a company with a high payout, because a low payout decreases T s.

Copyright © 2002 by Harcourt Inc.All rights reserved. When Miller brought in personal taxes, the value enhancement of debt was lowered. Why? 1.Corporate tax laws favor debt over equity financing because interest expense is tax deductible while dividends are not. (More...)

Copyright © 2002 by Harcourt Inc.All rights reserved. 2.However, personal tax laws favor equity over debt because stocks provide both tax deferral and a lower capital gains tax rate. 3.This lowers the relative cost of equity vis-a-vis MMs no-personal- tax world and decreases the spread between debt and equity costs. 4.Thus, some of the advantage of debt financing is lost, so debt financing is less valuable to firms.

Copyright © 2002 by Harcourt Inc.All rights reserved. What does capital structure theory prescribe for corporate managers? 1.MM, No Taxes: Capital structure is irrelevant--no impact on value or WACC. 2.MM, Corporate Taxes: Value increases, so firms should use (almost) 100% debt financing. 3.Miller, Personal Taxes: Value increases, but less than under MM, so again firms should use (almost) 100% debt financing.

Copyright © 2002 by Harcourt Inc.All rights reserved. Firms dont follow MM/Miller to 100% debt. Debt ratios average about 40%. However, debt ratios did increase after MM. Many think debt ratios were too low, and MM led to changes in financial policies. Do firms follow the recommendations of capital structure theory?

Copyright © 2002 by Harcourt Inc.All rights reserved. Define financial distress and agency costs. Financial distress: As firms use more and more debt financing, they face a higher probability of future financial distress, which brings with it lower sales, EBIT, and bankruptcy costs. Lowers value of stock and bonds. (More...)

Copyright © 2002 by Harcourt Inc.All rights reserved. Agency costs: The costs of managers not behaving in the best interests of shareholders and the resulting costs of monitoring managers actions. Lowers value of stock and bonds.

Copyright © 2002 by Harcourt Inc.All rights reserved. How do financial distress and agency costs change the MM and Miller models? MM/Miller ignored these costs, hence those models show firm value increasing continuously with leverage. Since financial distress and agency costs increase with leverage, such costs reduce the value of debt financing.

Copyright © 2002 by Harcourt Inc.All rights reserved. Heres a valuation model which includes financial distress and agency costs: X represents either T c in the MM model or the more complex Miller term. Now, optimal leverage involves a tradeoff between the tax benefits of debt and the costs associated with financial distress and agency. V L = V U + XD - -.

Next, draw on marketable securities. Then, issue new debt. Finally, and only as a last resort, issue new common stock. What is the pecking order theory of capital structure?

Copyright © 2002 by Harcourt Inc.All rights reserved. Does the pecking order theory make sense? Explain. Is the pecking order theory consistent with the trade-off theory? It is consistent with the asymmetric information theory, in which managers avoid issuing equity. It is not consistent with trade-off theory.

Copyright © 2002 by Harcourt Inc.All rights reserved. Theory recognizes that market participants do not have homogeneous expectations-- managers typically have better information than investors. Thus, financing actions are interpreted by investors as signals of managerial expectations for the future. What is the asymmetric information theory of capital structure? (More...)

Copyright © 2002 by Harcourt Inc.All rights reserved. Managers will issue new common stock only when no other alternatives exist or when the stock is overvalued. Investors recognize this, so new stock sales are treated as negative signals and stock price falls. Managers do not want to trigger a price decline, so firms maintain a reserve borrowing capacity.
