Old Jeans Berhad (OJB) is considering a project which requires an investment of RM100, 000 in machinery. This machinery will be depreciated using straight-line over four years period and the salvage value is estimated to be zero by the end of this machine useful life. The project sales forecast for the next four years is as follows: The selling price per unit is RM15 and the variable cost per unit is RM10. The project requires an increase in net working capital of RM40,000 in the initial year and will be fully recovered at the end of the project. The firm's required return on investment of 12%. OJB thinks that the unit sales, selling price and variable cost projections are accurate to within 10%. Note: The calculation on depreciation, fixed cost and the effect on tax is ignored for this question. From the given information, you are required to answer the following questions. a. Determine the upper and lower bounds for this projection. (4 Marks) b. Based on your answer in part (a), prepare the Cash Flows Analysis clearly showing the Net Present Value (NPV) for the best and worst-case scenario. (4 Marks) c.
