Project Appraisal Methods

This assignment delves into the analysis of project financial viability using three key methods: Net Present Value (NPV), Internal Rate of Return (IRR), and Payback Period. The text focuses on comparing these methods, highlighting their limitations, and emphasizing the NPV method's suitability for evaluating replacement decisions. It utilizes a case study involving Watley to demonstrate the application of NPV in assessing the financial worthiness of a project.

Finance: Appraisal of Capital Investment Decisions
1

Introduction
The capital investment decisions involve huge sum of money therefore it is of paramount
importance for the management to make these decisions after carrying out the analysis
effectively. There are various tools and techniques being applied for the purpose of analyzing the
financial viability of a capital investment, the most prominent among them is the net present
value technique (NPV) (Atrill and McLaney, 2008). The other techniques involve internal rate of
return (IRR), payback period, and accounting rate of return. In this context, the report presented
here provides discussion on various techniques of capital investment analysis such as NPV, IRR,
Payback period etc. Further, the report also demonstrates the practical application of NPV
technique in analyzing the machine replacement decision (Atrill and McLaney, 2008).
Part-1
Watley’s is considering replacing the old machine with the automated new machine
which is expected to reduce the manufacturing cost to a large extent over the period of four
years. The machine will initially cost £60,000 and require a sum of £2,000 being incurred per
year on maintenance. The new machine is expected to reduce the manufacturing labor cost by
£22,000 for four years. In order to analyze that whether this replacement decision would be
financially worthwhile or not, the NPV has been computed as below:
NPV of Project
Year Cash Flows PVF@10% PV
0 (60,000.00) 1.000 (60,000.00)
1 20,000.00 0.909 18,181.82
2 20,000.00 0.826 16,528.93
3 20,000.00 0.751 15,026.30
4 20,000.00 0.683 13,660.27
NPV 3,397.31

It can be observed from the computations shown in the table given above that the NPV of
replacement is £3,397.31. The positive NPV of replacement decision reflects that it would be
worthwhile to implement the replacement of the machine. Thus, it is advised that the company
should go for replacement of old machine with the new automated machine.
Part-2
There are three crucial elements found in any capital investment decisions such as cash
inflows, outflows, and discount rate. In order to compute cash inflows, outflows, and discount
rate, there are made a number of assumptions. The capital investment decision is futuristic and
thus, assumptions are made about the future outlook in respect of these three crucial elements
(Röhrich, 2014). The computation of cash inflows requires estimation about the sale units and
unit price. Similarly, estimations are made in respect of costs to arrive at the cash outflows.
Further, the determination of discount rate requires various assumptions about the risk and
expected return of the investors (Röhrich, 2014).
The discounting of cash flows is normally done at the desired rate of return of the
investors which in the case of a company is taken as WACC. Further, the computation of WACC
is based on the estimations of cost of equity and after tax cost of debt. The estimation of cost of
debt is however simple and requires less assumptions but the same is not the case with cost of
equity. The cost of equity is computed based on various assumptions, for example, assumption
about future dividend payment, growth rate, risk free rate, and market risk premium. Further, the
assumptions are also required to be made about the life span of the project in which capital
investment is being made (Röhrich, 2014).

In regards to the replacement of old cutting machine with the new automated machine,
the two crucial assumptions are savings in the labor cost and useful life of machine. It has been
assumed that the new machine will cause savings in the labor cost of £22,000 annually. Further,
it has been assumed that the machine will require annual maintenance incurring a sum of £2,000.
These assumptions are based on the initial estimates only and thus, there always remains
possibility of variance (Drury, 2008). It may be possible that the maintenance cost is increased in
future and thus, the company may incur additional money or it may decrease also resulting in
increase in savings. Further, it has been assumed that the new machine will be in a workable
condition for 4 years. However, it may or may not or it may end up with more years (Drury,
2008).
It is essential to note that the assumptions should be made in such a way that the
possibility of variance is reduced. If the assumptions are made precisely, the possibility of
achieving the desired outcome is increased. For example, if the life of new machine is not
estimated precisely and suppose if the machine is retired from use after three years, the resultant
NPV would be less than £3,397.31 which might make the replacement decision less attractive.
Thus, it is crucial to make the assumption precisely considering the past and future performance
(Chapman, Hopwood, and Shields, 2011).
Part-3
It has already been discussed that there are various capital investment appraisal
method/techniques. Some of them involve the use of time value of money and some do not. For
example, the NPV and IRR techniques use the concept of time value of money while the
4

payback period and accounting rate of return are the techniques that do not implicate the use of
time value of money (Chapman, Hopwood, and Shields, 2011).
The net present value technique requires the calculation of present value of net cash
inflows and comparing the same with the initial capital outlay. If the initial capital outlay is less
than the present value of net cash inflows, the NPV is positive and hence the project becomes
acceptable. On the other hand, if the initial capital outlay is greater than the present value of net
cash inflows, the NPV is negative and hence the project is liable to be rejected. Keeping the NPV
aside, the project can also be appraised using the IRR technique. The internal rate of return is the
breakeven return that the project must earn in order to be called financially worthwhile. The
internal rate of return is compared with the cost of capital and if the IRR is greater than the cost
of capital, the project is accepted else it is rejected (Chapman, Hopwood, and Shields, 2011).
The internal rate of return technique is also widely used but it suffers from certain
limitations which restricts its use in the special circumstances. For instance, when the series of
cash flows involves cash outflows at more than one occasion, it may result in multiple IRRs
giving conflicting views (Gotze, Northcott, and Schuster, 2016). However, when it comes on
comparing more than one mutually exclusive project with each other; the IRR is considered
better than NPV. Further, the payback period is also used in analyzing the financial viability of
the project. The payback period computes the time duration within which the amount of initial
investment would be recovered. In most of the cases, the payback period method is used in
conjunction with other methods such as NPV and IRR. The payback period used singly in
analyzing the project’s financial worth would be less useful (Gotze, Northcott, and Schuster,
2016).

In the current case, there is single project under consideration. The financial viability of a
single project could be assessed applying any of the three methods such as NPV, IRR, and
payback period. The results of all three methods would lead to same conclusion about acceptance
or rejection of the project. The NPV method has been applied in assessing that whether the
replacement decision is financially worthwhile or not. If the IRR or payback period is applied,
the result would be same i.e. the project would be acceptable (Gotze, Northcott, and Schuster,
2016).
Conclusion
In analyzing the project’s financial viability, the management of the company may
consider applying a number of methods such as NPV, IRR, and payback period. The
management should consider that these methods have different characteristics and some specific
situations may require use of specific method. However, the NPV method is commonly applied
and it is considered as one of the most appropriate and suitable to all conditions method. In
analyzing the replacement decision of Watley, the NPV method has been applied which shows a
positive NPV of £3,397.31.
