These limitations include its settle perspective, exclusion of non-financial benefits, overemphasis on the oblivious-run, faulty assumptions near the status quo, inconsistent treatment of puffiness, and promotion of dysfunctional/ chisel behaviour.Previous authors, including Hastie (1974) Ramasesh and Jayakumar (1993) and Adler (2000) bugger off enumerated and discussed the various sins of DCF. * The objections against the use of DCF for uppercase investment appraisal fox often been objected to themselves. Kaplan (1986), for typesetters case, feels that the hypothetical limitations of DCF are in truth a limitation of the user and not of the technique. For example, the selection of a tranquil discount rate is a failure of the user and not of the technique itself. Likewise, the inconsistent treatment of inflation, the overemphasis on the short-term, faulty assumptions a play the status quo alternative, the adoption of a narrow organisational perspective, and manipulative and cheating behaviour are again all mistakes of the user.Even the difficulty of including non-financial benefits is seen as a lack of the financial analysts imagination instead a than an inhe rent shortcoming of the technique. To help overcome the problems of DCF for p for each oney investment decision-making, proponents of real options opening have argued for the tandem bicycle use of the Black and Scholes (1973) model and DCF.

Not provided(prenominal) do these occasions happen quite frequently, provided alike they become increasingly common as the decision moves from the operationally mundane to the strategicalally critical.The mis glance overplication of swell investment appraisal techniques * Surveys of capital budgeting practices in the UK and USA reveal a trend towards the increase use of much sophisticated investment appraisals requiring the application of discounted currency unravel (DCF) techniques. Several writers, however, have claimed that companies are under expend because they misapply ormisinterpret DCF t echniques. * the only justification we can think of for using the history rate of slip by method is because top management believe that reported profits have an impact on how financial markets label a company. This is upgrade reinforced in many companies by linking management rewards to short-term financial report carding measures. Thus a projects impact on the financial accounting measures used by financial markets would front to be a factor that is taken into account within the decision-making mold. Dimson and Marsh (1994) have expressed reside that many UK companies may be using excessively high discount grade to appraise investments and, as a return, these companies are in danger of underinvesting. In the USA it has also been alleged that loyals use discount rates to evaluate investment projects that are higher than their estimated approach of capital (Porter, 1992). Conclusions Ducht an UK companies * on the whole the UK case exact companies apply combined methods of investment appraisal and close to of them combine the DCF techniques with the value based management methods, such(prenominal) as SVA and EVA. The combination among the Netherlands companies, however, is mostly with the accounting based measures. Project decision-making in most of the case line of business companies is found decentralized, which provides the benefits of teamwork in project management. * In terms of appraisal model selection, however, the result is heterogeneous. Most companies elect to apply combined methods of appraisal. Uniform methods of evaluation are no applied crossways all stages of a project, which forget make difficult the comparison of project values at varied stages. Although research in capital budgeting suggests the use of quantitative models for R&D and ICT projects, the application is not found in practice. In contrary, firms are relying on qualitative and non-standard approaches.This does not have rigorous theoretical basis, and hence, the decision-making process may not get an demandable yardstick for its rationality. Capital inv appraisal of new technologies Problems, misconceptions and research directions * requital methods are understaffed appraisal techniques and should never be used alone.

The bias due to the use of short-term financial criteria can be removed by the use of measures reflecting the longer-term benefits of present investments. In principle, then, the biases of capital-investment appraisals are avoidable, but one difficulty remains.

To calculate the necessitate rate of return we use the CAPM Managers? interests disparate from shareholders? ones so higher rate or return determined. Then, again, the critic/problem is not of the appraisal method but of its application or understanding Theory-practice gap in .. UK The survey results depict that UK corporations have increasingly adopted prescribed text bind financial analysis. The stage has this instant been reached where only a small minority do not make use of discounted money flows, egg risk analysis, ppropriate inflation adjustment and post-auditing. However, managers continue to employ simple-mindedr rules-of-thumb techniques. There has not, in general, been a replacement of one set of methods with another, but rather, a widening of the range of ways of analysing a financial decision. Why DCF are bad for business and why business schools should stop using it It has been said, Life must be lived precedent but can only be understood backwards. There is no denying that DCF is wonderful at smell backwards and calculating, for example, the true NPV a project has earned. Some condemnations, generally when commonplace, operational decisions are involved, DCF can even work as a forward-looking tool.To work in this manner, however, requires the relevant cash flow data to be either present or, perhaps with a bit of work, discoverable. DCF does not work well when the decision at hand is strategic in nature. In these situations, the data is often neither present nor discoverable in time for an ex ante evaluation. Only after the decision is made does useful data likely become available. The status described here is well captured in the lyrics of the Rolling Stones song You Cant Always rise What You Want You cant always get what you want But if you settle sometimes, well you aptitude find You get what you need. When it comes to matters that really matter, DCF and real options theory fail to enlighten us.Instead, they sap managers energy by focusing their attention on Paretos trivial many at the cost of his vital few. In the end, managers end up missing the forest in their search for the non-existent trees. It is time that as educators, we rediscovered the vital few and culled out the trivial many topics that have crept into our course outlines. DCF should be one of the first topics we drop or at a minimum drastically prune back. It is not only a prime example of the trivial many, but it is a potential hazard to firms that use it for decisions that affect firm strategy. Do I hear any other offers? The missapplication of capital investment appraisal techniques The use of buttoned-up cash flow foretastes, combined with the incorrect treatment of nflation and excessive discount rates observed in the survey suggests that many UK organizations may be rejecting profitable investments. Given these problems it could be argued that DCF procedures should be abandoned or given little weight in long-term investment decisions. We strongly disagree. DCF procedures should not be ignored or relegated in importance merely because they might be used incorrectly. Instead, decisionmakers should recognize potential problems and be careful to project that the financial appraisal is performed correctly. CRI TICS TO PAYBACK PERIOD Capital inv appraisal of new technologies Problems, misconceptions and research directionsThe objection to requital methods is that they ignore all cash flows after the desired payback period, which may be as short as 2 or 3 years. Thus they take no account of the long-term advantages that many large investments in new process technology bring, so the use of payback criteria is worthy of comment. 5 vengeance can be insensitive to considerable variation among projects (in terms of their cash flows). 6 Payback methods are simple rules of thumb. Their attraction is their simplicity, and robustness for making judgements on possibly optimistic make upings and uneasily quantified business risks. However, they do ignore medium- and long-term cash flows, and it is perhaps surprising that they seem to be regarded as effective tools of financial analysis.Net present valueFirms generally have many investment opportwholeies available. Some of these investment opportun ities are valuable and others are not. The essence of successful financial management is identifying which opportunities will increase shareholder wealth. There are three basic and related concepts that form the very foundation of modern day finance present value, net present value (NPV) and opportunity cost. Present value gives the value of cash flows generated by an investment and NPV gives the effective net benefit from an investment after subtracting its costs. Opportunity cost represents the rate of return on investments of comparable risk. Application of these concepts enables us to value different kinds of assets, especially those which are not commonly traded in well-functioning markets.NPV of an asset or investment is the present value of its cash flows less the cost of acquiring the asset. Smart investors will only acquire assets that have positive NPVs and will attempt to maximize the NPV of their investments. The rate of return received from an investment is the profit d ivided by the cost of the investment. Positive NPV investments will have rates of return higher than the opportunity cost. This gives an alternate investment decision rule. Good investments are those that have rates of return higher than the opportunity cost. This opportunity cost can be inferred from the capital market and is based on its risk characteristics of the investment.To assess why Net Present Value leads to come apart investment decisions than other criteria, let us start with a review of the NPV approach to investment decision making and then present four other widely used measures. These are the payback period, the oblige rate of return, the internal rate of return (IRR) and profitableness index. The measures are inferior to the NPV and should not, with the qualified exception of the IRR, ordinarily be relied upon to provide sound investment decisions. These measures are commonly used in practice.The NPV represents the value added to the business by the project or t he investment. It represents the increase in the market value of the stockholders wealth. Thus, accepting a project with a positive NPV will make the stockholders better off by the amount of its NPV. The NPV is the theoretically correct method to use in most situations. Other measures are inferior because they often give decisions different from those given by following the NPV rule. They will not serve the best interests of the stockholders (Brealey, 2002).To calculate NPV we should firstly forecast the incremental cash flows generated by the project and determine the appropriate discount rate, which should be the opportunity cost of capital. Then calculate the sum of the present values (PV) of all the cash flows generated by the investment. NPV = PV of cash inflows sign investment. To make decision on investment, we should accept projects with NPV greater than zero and for mutually scoopful projects, accept the project with the highest NPV, if the NPV is positive. The NPV repres ents the value added to the stockholders wealth by the project. The discount rate should reflect the opportunity cost of capital or what the stockholders can expect to earn on other investments of equivalent risk (Brealey, 2002).The NPV approach correctly accounts for the time value of money and adjusts for the projects risk by using the opportunity cost of capital as the discount rate. Thus, it clearly measures the increase in market value or wealth created by the project. The NPV of a project is not impact by promotion it with another project. In other words, NPV(A+B) = NPV(A) + NPV(B). The NPV is the only measure that provides the theoretically correct measure of a projects value (Ross, 2002).Payback Period. The payback period is simply the time taken by the project to return your initial investment. The measure is very popular and is widely used it is also a flawed and unreliable measure. It is simple to calculate and informal to comprehend. However, payback period has very l imited economic meaning because it ignores the time value of money and the cash flows after the payback period. It can be inconsistent and the rank of projects may be changed by packaging with other projects.Discounted payback is a modified version of the payback measure and uses the discounted cash flows to compute payback. This is an proceeds over the traditional payback in that the time value of money is recognized. A project, which has a mensural discounted payback, will have a positive NPV. However, the other disadvantages of payback still apply. It is also not simple anymore ( enthronement Criteria).Book Rate of Return (BRR). This is a rate of return measure based on accounting earnings and is defined as the ratio of book income to book assets. Accounting earnings are reported by firms to the stockholders and the book return measure fits in with the reported earnings and the accounting procedures used by firms.However, the measure suffers from the serious drawback that it do es not measure the cash flows or economic profitability of the project. It does not consider the time value of money and gives too much weight to distant earnings. The measure depends on the choice of depreciation method and on other accounting conventions. BRR can give inconsistent ranking of projects and rankings may be altered by packaging. There is very little relationship between the book return and the IRR. (Brealey, 2002).Internal Rate of Return (IRR). IRR is defined as the discount rate at which the NPV equals zero. utilise properly, the IRR will give the same result as the NPV for independent projects and for projects with normal cash flows. As long as the cost of capital is less than the IRR, the NPV for the project will be positive. IRR can rank projects incorrectly, and the rankings may be changed by the packaging of the projects. For mutually exclusive projects, IRR can give incorrect decisions and should not be used to rank projects. If one must use IRR for mutually e xclusive projects, it should be done by calculating the IRR on the differences between their cash flows (Ross, 2002).Profitability Index. Occasionally, companies face resource modesty or capital rationing. The amount available for investment is limited so that all positive NPV projects cannot be accepted. In such cases, stockholder wealth is maximized by taking up projects with the highest NPV per dollar of initial investment. This approach is facilitated by the profitability index (PI) measure. Profitability index is defined as NPV/Investment. The decision rule for profitability index is to accept all projects with a PI greater than zero.This rule is equivalent to the NPV rule. The modified rule applied in the case of capital rationing is to accept projects with the highest profitability index first, followed by the one with next highest, and so on till the investment dollars are exhausted. This rule will maximize the NPV and stockholder wealth. If the resource constraint is on so me other resources, the profitability index needs to be modified to measure the NPV per unit of the resource that is rationed. The profitability index cannot cope with mutually exclusive projects or where one project is possible on another (Brealey, 2002).Thus, comparing NVP with other criteria we can assert that NPV is superior to other criteria. First, it is the only measure, which considers the time value of money, properly adjusting for the opportunity cost of capital. Second, it gives consistent measures of the projects value (i.e. not affected by packaging with other projects). Third, it clearly measures the value added to the stockholders wealth. The only exception to the superiority of NPV is when the firm is trammel by capital rationing. This implies that the firm cannot finance all positive NPV projects and should therefore choose projects that give the highest NPV for each dollar of investment. The profitability index that is defined as the ratio of NPV to the investmen t amount is used to strike this selection.However, the other criteria for the evaluation of projects are found to be popular in practice. If using them, we should make sure we use them in the best possible way and understand the limitations of them. For example, we should always compare mutually exclusive projects on the basis of the difference between their cash flows, because that it is the cash flows that determine the value of a project. shortsighted forecast of the cash flows can be far more disastrous than using the wrong appraisal technique. Cash flow forecasts are difficult to make and can be expensive. It does not make guts to waste the forecasts by using an inferior method of evaluation.ReferencesBrealey, Richard A. & Myers, Stewart C. (2002). Principles of Corporate Finance, 7th ed. Chapters 5 6.
