In section 2, the alternatives facing a corporation, given the opportunity to purchase a future single riskless cash inflow which is taxable, are examined. It is shown that, if the corporation wants, independently of its borrowing/dividend decision, to avoid accepting such projects when some of its shareholders would prefer that they not be accepted, the corporation should calculate the present value of riskless after-tax cash flows by discounting with the before-tax riskless interest rate. The implications for capital budgeting are illustrated with a leasing example.
