Even if the value of the interest rate tax shield to the corporation and to individual shareholders is restricted to that on “nonrecourse” debt, so that Dp ¼ aDc and rpD ¼ rcD, “adjusted” NPV will not coincide with the viewpoint of all shareholders. If the shareholder finds it advantageous to sell (now or later) rather than receive the
uncertain future dividend, and there is a (full or partial) deduction for some acquisition cost, this will increase the left hand side of the above inequality but not alter the conclusion in favour of “base case” NPV.
