MODIGLIANI & MILLER’S THEORY
The firm’s total cash flows still equal the cash flows of the project, and therefore have the same present value of 1000 € calculated earlier.
Because the cash flows of the debt and equity sum to the cash flows of the project, by the Law of One Price the combined values of debt and equity must be 1000 €.
Therefore, if the value of the debt is 500 €, the value of the levered equity must be E = 1000 € - 500 € = 500 €.
