4, Conclusion:
Regarding to quantitative method, the best choice is only option 3 which states that we
replace the current fleet with the current generation jets and keep that forever because this
option generates the highest NPV. Our decision is even more valid if the new generation
small jets are available to use beyond 3 years as we still expect to keep our current
generation jets.
However, we do need to consider about the qualitative factors which also play a significant
role in decision making. For example, regardless of quantitative factors, managers still
want to replace the current jets with the new jets to remain the modern image of the
company as well as improve the satisfaction of customers and productivity. Moreover, if
company still goes for option 3 meaning that it refuses updating to the new jets; company
will face with the risk that its competitors will enter the market with the new jets after 3
years. Therefore, company’s cash flow from current jets will be eroded, possibly resulting
in negative NPV.
Case 2:
1, Project context
The project involves whether to keep the old machine or replace it with the new one.
Based on the data provided, our calculation has been modeled in incremental cash flow. To
complete the analysis, we also need to consider the risks associated with the new
investment by using sensitivity analysis rather than just focus on the NPV of alternatives.
2, Assumptions:
Firstly, all cash flows are in real terms. Consequently, those cash flows under the four
proposals will be discounted using the real required rate of return.
Secondly, we assume that the residual value of old and new machine is equal to 0
Thirdly, all cash flows are expected to occur at the end of each year. This makes our
calculation simple and still reasonable.
Fourthly, assume that the marginal tax, the cost of capital and the inflation rate are
unchanged. However, this assumption seems unrealistic because unstable economy
together with regular changes in the regulation is likely to change the marginal tax and the
