Cash Flows and Other Topics

in Capital Budgeting


10-1. We focus on cash flows rather than accounting profits because these are the flows that the firm receives and can reinvest. Only by examining cash flows are we able to correctly analyze the timing of the benefit or cost. Also, we are only interested in these cash flows on an after tax basis as only those flows are available to the shareholder. In addition, it is only the incremental cash flows that interest us, because, looking at the project from the point of the company as a whole, the incremental cash flows are the marginal benefits from the project and, as such, are the increased value to the firm from accepting the project.

The firm needs to consider alternative uses of funds if the project with the lowest net present value is chosen.

10-8. The time disparity problem and the conflicting rankings that accompany it result from the differing reinvestment assumptions made by the net present value and internal rate of return decision criteria. The net present value criterion assumes that cash flows over the life of the project can be reinvested at the required rate of return; the internal rate of return implicitly assumes that the cash flows over the life of the project can be reinvested at the internal rate of return.

9. The problem of incomparability of projects with different lives is not directly a result of the projects having different lives but of the fact that future profitable investment proposals are being affected by the decision currently being made. Again the key is: "Does the investment decision being made today affect future profitable investment proposals?" If so, the projects are not comparable. While the most theoretically proper approach is to make assumptions as to investment opportunities in the future, this method is probably too difficult to be of any value in most cases. Thus, the most common method used to deal with this problem is the creation of a replacement chain to equalize life spans. In effect, the reinvestment opportunities in the future are assumed to be similar to the current ones. Another
