Investment Appraisal - Methods And Considerations
Project Evaluation Under Risk and Uncertainty
A firm conducts its business in a rapidly changing and highly
competitive environment. The changing environment poses both opportunities and
threats for the company.
For example, change in Government policy may cause change in prices of
inputs and outputs, demand and supply of products/services. Similarly,
technology change may cause the production cost change. Also the cash inflows
and outflows cannot be ascertained with accuracy. Therefore, evaluation of
investment projects under uncertainty and risk become important.
Characteristically, a capital investment decision involves
largely irreversible commitment of resources that is generally subject to a
significant degree of risk. Such decisions have far reaching effects on a
company's profitability and flexibility over the long-term, thus requiring that
they be part of a carefully developed strategy that is based on reliable
forecasting procedures.
Typical examples of capital budgeting topics are:
-
expansion projects;
-
replacement projects;
-
selection among alternatives; and
- buy or
lease decisions.
Good capital budgeting decisions, based on sound investment
appraisal procedures, should improve the timing of capital acquisitions as well
as the quality of capital acquisitions.
Investment in expansion/ modernization is one of the main
sources of economic growth, since it is required not only to increase the total
capital stock of equipment and buildings, but also to employ labor in
increasingly productive jobs as old plant is replaced by new.
Various criticisms have been put forward in relation to the
methods of appraisal that many companies employ. Among the most important are:
1.
Although most companies only make investment decisions after
careful consideration of the likely costs and benefits as they see them, these
decisions are often reached in ways that are unlikely to produce the pattern or
level of investment that is most favorable to the economy's growth-or even most
profitable to the company.
2.
Many companies apply criteria for assessing investment projects
that have little relevance to the measurement of the expected rate of return on
capital invested (ROI).
3.
Even though a calculation of the ROI of each project may be
made, the methods used vary widely and are sometimes so arbitrary as to give
almost meaningless results. (For instance, a failure to assess returns after tax
is a frequent weakness of many widely used methods, since alternative
opportunities can only be effectively compared and appraised on an after-tax
basis.)
This faulty use of means of investment appraisal may result
in over-cautious investment decisions in which too high a rate of return is
demanded before the equipment is installed. This causes delay in economic
growth. Alternatively, faulty methods may mean that investment decisions are
made that result in the selection of projects that yield an unduly low ROI. This
causes a waste of scarce capital resources, which is also unfavorable to
economic growth.
No matter which technique is adopted for investment
appraisal, the following steps need to be followed:
1.
Determine the profitability of each proposal;
2.
Rank the proposals in accordance with their profitability;
3.
Determine the cut-off rate;
4.
Determine which projects are acceptable and which unacceptable
in relation to the cut off rate; and
5.
Select the most profitable proposals in accordance with the
constraints of the company's capital budget.
