You are evaluating an 8-year project where you need to invest $1,000 upfront (i.e., at t0). Years 1, 2, and 3 produce positive cash flow figures of $100, $200, and $300 respectively. In Year 4 you need to invest another $500. In Year 5 there is another positive cash flow of $400. In Year 6 you need to invest another $200. Year 7 produces $600 in positive cash flow and Year 8 produces $700. Your discount rate is 8%. What is the NPV of this project? What is the IRR? How would lowering the discount rate affect IRR? Should you proceed with this project? Why or why not? Please draw a number line.
