Green \& Company is considering investing in a robotics manufacturing line. Installation of the line will cost an estimated $15.9 million. This amount must be paid immediately even though construction will take three years to complete (years 0,1 , and 2). Year 3 will be spent testing the production line and, hence, it will not yield any positive cash flows. If the operation is very successful, the company can expect after-tax cash savings of $10.9 million per year in each of years 4 through 7 . After reviewing the use of these systems with the management of other companies, Green's controller has concluded that the operation will most probably result in annual savings of $8.1 million per year for each of years 4 through 7 . However, it is entirely possible that the savings could be as low as $3.9 million per year for each of years 4 through 7 . The company uses a 12 percent discount rate. Use Exhibit A.8. Required: Compute the NPV under the three scenarios. Note: Round PV factor to 3 decimal places. Enter your answers in thousands of dollars, rounded to the nearest whole number. Negative amounts should be indicated by a minus sign. Answer is complete but not entirely correct. Green \& Company is considering investing in a robotics manufacturing line.
