N1 - 47 N2 - The starting point of this article deals with an applied problem of capital budgeting that a firm whose projects are subject to various tax rates (as is often the case in the oil industry) may encounter: how to value a project partly financed by borrowing and subject to a different tax rate from the one used to determine the discount rate of the firm? Surprisingly enough, answering this question led us to develop a unique formulation of the different conventional investment decision methods (standard WACC, Arditti-Levy, Equity Residual, Myers’ APV). Moreover, we generalize the Modigliani-Miller relationship to the case of a project of any duration.
