Balance Sheet Liabilities Assets Net Worth Modigliani Miller Theorems on Leverage
Value of the Firm According to Modigliani-Miller • Net Worth • Plus Liabilities In other words, ASSETS !!!
MM-1 In a world of no taxes “Value of the Firm” Is independent Of the leverage ratio Irrelevance of Leverage Theorem
Broader Implications from MM-I • US inadequately levered in the 1960’s • US still relatively less levered that rest of world
MM-II “Cost of equity capital” is a linear function of the debt/equity ratio “Cost of debt capital” is whatever the going interest rate is
