Harrington Enterprises is facing a decision this capital budgeting year. It has 2 projects to decide upon. Each one would cost $25,000,000 today. Harringtons WACC is 10%. Cash flows for each are below (in $mil).

Year Project A Project B

1 $5 $20 2 10 10 3 15 8 4 20 6

For project A, calculate: 1. (5) NPV 2. (7) IRR 3. (7) Payback Period. 4. (6) If A and B are mutually exclusive, which should Harrington accept or reject using the NPV method? 5. (10) What would your answer have been if the firm used ONLY the Payback period to decide which projects to accept/reject? Explain what this depends critically on and why. 6. (7) What would your answer have been if the firm used ONLY the IRR rule to decide which projects to accept/reject? 7. (8) Which of the above is the correct approach? NPV, IRR or PP? I would like a paragraph and justification using everything you know. The fuller and more correct the answer the more points you will get.
