The project would also need an investment in working capital of $8,000, from the
beginning of Year 1.
The company uses a discount rate of 11% to evaluate its investments, but has an
additional rule that projects will not be undertaken unless they pay back within
three years.
Required
Calculate the NPV of the project at the discount rate of 11%.
Using the NPV you have calculated at 11%, and the NPV at a discount rate of 15%,
estimate the internal rate of return (IRR) of the project.
Calculate the payback period and state whether the project should be undertaken.
10 Investment appraisal methods
Congo is considering whether to invest in either of two mutually-exclusive
projects, Project 1 and Project 2. Both projects involve the purchase of machinery
with a life of five years.
Project 1: The machine would cost $556,000 and would have a net disposal value
of $56,000 at the end of Year 5. The project would earn annual cash flows
(receipts minus payments) of $200,000.
Project 2: The machine would cost $1,616,000 and would have a net disposal
value of $301,000 at the end of Year 5. The project would earn annual cash flows
(receipts minus payments) of $500,000.
Congo uses the straight-line method of depreciation. Its cost of capital is 15%.
Ignore taxation, inflation and investment in working capital.
Required
(a) For each of the two projects, calculate:
(i) the accounting rate of return ratio, over the project life (average annual
accounting profit as a percentage of the average book value of the
investment, to the nearest one per cent)
(ii) the payback period, to the nearest month
(iii) the net present value, and
(iv) the internal rate of return to the nearest one per cent.
(b) State which project, if any, you would select for acceptance.
Note
At a discount rate of 25%, the following discount factors apply:
Year 5: 0.328.
Years 1 – 5: 2.689.
