第1题:

(c) Discuss the reasons why the net present value investment appraisal method is preferred to other investment

appraisal methods such as payback, return on capital employed and internal rate of return. (9 marks)


正确答案:
(c) There are many reasons that could be discussed in support of the view that net present value (NPV) is superior to other
investment appraisal methods.
NPV considers cash flows
This is the reason why NPV is preferred to return on capital employed (ROCE), since ROCE compares average annual
accounting profit with initial or average capital invested. Financial management always prefers cash flows to accounting profit,
since profit is seen as being open to manipulation. Furthermore, only cash flows are capable of adding to the wealth of
shareholders in the form. of increased dividends. Both internal rate of return (IRR) and Payback also consider cash flows.
NPV considers the whole of an investment project
In this respect NPV is superior to Payback, which measures the time it takes for an investment project to repay the initial
capital invested. Payback therefore considers cash flows within the payback period and ignores cash flows outside of the
payback period. If Payback is used as an investment appraisal method, projects yielding high returns outside of the payback
period will be wrongly rejected. In practice, however, it is unlikely that Payback will be used alone as an investment appraisal
method.
NPV considers the time value of money
NPV and IRR are both discounted cash flow (DCF) models which consider the time value of money, whereas ROCE and
Payback do not. Although Discounted Payback can be used to appraise investment projects, this method still suffers from the
criticism that it ignores cash flows outside of the payback period. Considering the time value of money is essential, since
otherwise cash flows occurring at different times cannot be distinguished from each other in terms of value from the
perspective of the present time.
NPV is an absolute measure of return
NPV is seen as being superior to investment appraisal methods that offer a relative measure of return, such as IRR and ROCE,
and which therefore fail to reflect the amount of the initial investment or the absolute increase in corporate value. Defenders
of IRR and ROCE respond that these methods offer a measure of return that is understandable by managers and which can
be intuitively compared with economic variables such as interest rates and inflation rates.
NPV links directly to the objective of maximising shareholders’ wealth
The NPV of an investment project represents the change in total market value that will occur if the investment project is
accepted. The increase in wealth of each shareholder can therefore be measured by the increase in the value of their
shareholding as a percentage of the overall issued share capital of the company. Other investment appraisal methods do not
have this direct link with the primary financial management objective of the company.
NPV always offers the correct investment advice
With respect to mutually exclusive projects, NPV always indicates which project should be selected in order to achieve the
maximum increase on corporate value. This is not true of IRR, which offers incorrect advice at discount rates which are less
than the internal rate of return of the incremental cash flows. This problem can be overcome by using the incremental yield
approach.
NPV can accommodate changes in the discount rate
While NPV can easily accommodate changes in the discount rate, IRR simply ignores them, since the calculated internal rate
of return is independent of the cost of capital in all time periods.
NPV has a sensible re-investment assumption
NPV assumes that intermediate cash flows are re-invested at the company’s cost of capital, which is a reasonable assumption
as the company’s cost of capital represents the average opportunity cost of the company’s providers of finance, i.e. it
represents a rate of return which exists in the real world. By contrast, IRR assumes that intermediate cash flows are reinvested
at the internal rate of return, which is not an investment rate available in practice,
NPV can accommodate non-conventional cash flows
Non-conventional cash flows exist when negative cash flows arise during the life of the project. For each change in sign there
is potentially one additional internal rate of return. With non-conventional cash flows, therefore, IRR can suffer from the
technical problem of giving multiple internal rates of return.

第5题:

PV Co is evaluating an investment proposal to manufacture Product W33, which has performed well in test marketing trials conducted recently by the company’s research and development division. The following information relating to this investment proposal has now been prepared.

Initial investment $2 million

Selling price (current price terms) $20 per unit

Expected selling price inflation 3% per year

Variable operating costs (current price terms) $8 per unit

Fixed operating costs (current price terms) $170,000 per year

Expected operating cost inflation 4% per year

The research and development division has prepared the following demand forecast as a result of its test marketing trials. The forecast reflects expected technological change and its effect on the anticipated life-cycle of Product W33.

It is expected that all units of Product W33 produced will be sold, in line with the company’s policy of keeping no inventory of finished goods. No terminal value or machinery scrap value is expected at the end of four years, when production of Product W33 is planned to end. For investment appraisal purposes, PV Co uses a nominal (money) discount rate of 10% per year and a target return on capital employed of 30% per year. Ignore taxation.

第6题:

(ii) Briefly discuss TWO factors which could reduce the rate of return earned by the investment as per the

results in part (a). (4 marks)


正确答案:
(ii) Two factors which might reduce the return earned by the investment are as follows:
(i) Poor product quality
The very nature of the product requires that it is of the highest quality i.e. the cakes are made for human
consumption. Bad publicity via a ‘product recall’ could potentially have a catastrophic effect on the total sales to
Superstores plc over the eighteen month period.
(ii) The popularity of the Mighty Ben character
There is always the risk that the popularity of the character upon which the product is based will diminish with a
resultant impact on sales volumes achieved. In this regard it would be advisable to attempt to negotiate with
Superstores plc in order to minimise potential future losses.

第9题:

下列各项不适合用内部收益率进行投资方案判断与选择的是( )。

A.内部收益率=基准收益率
B.方案的内部收益率有多个
C.内部收益率<基准收益率
D.内部收益率>基准收益率

答案:B
解析:
若投资方案的内部收益率大于或等于基准收益率或设定的收益率时,该方案可以接受;若投资方案的内部收益率小于基准收益率或设定的收益率时,该方案不可以接受。

第10题:

下述关于内部收益率的说法中,正确的有()。

A:内部收益率是使方案净现值等于零时的折现率
B:内部收益率大于等于基准收益率时,方案可行
C:内部收益率小于等于基准收益率时,方案可行
D:插值法求得的内部收益率小于方案真实的内部收益率
E:插值法求得的内部收益率大于方案真实的内部收益率

答案:A,B,E
解析:
使现金流量的净年值为零时的利率即是该方案的内部收益率;只要投资方案的内部收益率≥基准收益率或设定的收益率,则该方案的净现值(净年值、净将来值)就肯定≥0;只要投资方案的内部收益率<基准收益率或设定的收益率,则该方案的净现值(净年值、净将来值)就肯定<0;插值法求得的内部收益率常常大于方案真实的内部收益率。
