A car manufacturer has been experiencing financial difficulties over the past few years. Sales
have reduced significantly as a result of the worldwide economic recession. Costs have
increased due to quality issues that led to a recall of some models of its cars. Production
volume last year was 50 000 cars and it is expected that this will increase by 4% per annum
each year for the next five years. The company directors are concerned to improve
profitability and are considering two potential investment projects.
Project 1 – implement a new quality control process
The company has paid a consultant process engineerN$50 000 to reviewthe company’squality
processes. The consultant recommended that the company implement a new quality control
process. The new process will require a machine costing N$20 000 000. The machine is
expected to have a useful life of five years and no residual value. It is estimated that raw
material costs will be reduced by N$62 per car and that both internal and external failure costs
from quality failures will be reduced by 80%. Estimated internal and external failure costs per
year withoutthe new process, based on last year’s production volume of 50 000 cars, and their
associated probabilities are shown below:
Internal Failure Costs External Failure Costs
N$ Probability N$
N$
Probability
300 000 50% 1 300 000 60%
500 000 30% 1 900 000 30%
700 000 20% 3 000 000 10%
Internal and external failure costs are expected to increase each year in line with the number
of cars produced. The company’s accountant has calculated that this investment will result in
a net present value (NPV) of N$1 338 000 and an internal rate of return of 10.5%.
Project 2 – in-house component manufacturing
The company could invest in new machinery to enable in-house manufacturing of a
component that is currently made by outside suppliers. The new machinery is expected to
cost N$15 000 000 and have a useful life of five years and no residual value. Additional
working capital of N$1 000 000 will also be required as a result of producing the component
in-house. The price paid to the current supplier is N$370 per component. It is estimated that
the in-house variable cost of production will be N$260 per component. Each car requires one
component. Fixed production costs, including machinery depreciation, are estimated to
increase by N$5 000 000 per annum as a result of manufacturing the component in-house.
Depreciation is calculated on a straight line basis.
Additional Information
• The company is unable to raise enough capital to carry out both projects. The
company will therefore have to choose between the two alternatives.
• Taxation and inflation should be ignored. The company uses a cost of capital of 8%
per annum.
REQUIRED 
a) Calculate for Project 1 the relevant cash flows that the accountant should have used
for year 1 when appraising the project. All workings should be shown in N$000. 10
b) Calculate for Project 2 the net present value (NPV) and the internal rate of return
(IRR). All workings should be shown in N$000.

c) Advise the company directors which of the two investment projects should be
undertaken.
