Questions 1. What is the payback period? How is it calculated? 2. What weaknesses are commonly associated with the use of the payback period to evaluate a proposed investment? 3. How is the net present value (NPV) calculated for a project with a conventional cash flow pattern? And What are the acceptance criteria for NPV? 4. What is the internal rate of return (IRR) on an investment? How is it determined? 5. Fitch Industries is in the process of choosing the better of two equal-risk, mutually exclusive capital expenditure projects-M and N.
