Consider four projects, which you expect to generate the following cash flows: Year Project A Project B Project C Project D 0 (600,000) (6,000) (600,000) (600,000) 1 640,000 50,000 300,000 250,000 2 300,000 300,000 3 300,000 370,000 Your required return on all of the investments is 8%. For each project estimate the Payback Period, Internal Rate of Return (IRR), and Net Present Value (NPV). If these projects are independent which should you undertake? If the investments are mutually exclusive which should you accept?
