We want to help Marge Simpson, Inc. analyze the following business opportunities by using the following cash flow information. Assume Marge's opportunity cost of capital is 12%.

9. Net Present Value Net Present Value - Present value of cash flows minus initial investments. Opportunity Cost of Capital - Expected rate of return given up by investing in a project

10. Net Present Value NPV = PV - required investment

11. Net Present Value Terminology C = Cash Flow t = time period of the investment r = “opportunity cost of capital” The Cash Flow could be positive or negative at any time period. The Cash Flow could be positive or negative at any time period.

12. Net Present Value Net Present Value Rule Managers increase shareholders’ wealth by accepting all projects that are worth more than they cost. Therefore, they should accept all projects with a positive net present value.

If the projects are mutually exclusive, select How ‘Bout A Pretzel? If the projects are mutually exclusive, select How ‘Bout A Pretzel? Pretzel NPV > Falafel NPV. Pretzel NPV > Falafel NPV.

16. Payback Period (PB) Measures how long it takes to recovers a project’s cost. Measures how long it takes to recovers a project’s cost. Easy to calculate and a good measure of a project’s risk and liquidity. Easy to calculate and a good measure of a project’s risk and liquidity.

19. Internal Rate of Return (IRR) Internal Rate of Return is a project’s expected rate of return on its investment. Internal Rate of Return is a project’s expected rate of return on its investment. IRR is the interest rate where the PV of the project’s cash flows equals its cost. IRR is the interest rate where the PV of the project’s cash flows equals its cost. In other words, the IRR is the rate where a project’s NPV = 0. In other words, the IRR is the rate where a project’s NPV = 0. ∑CF t /(1 + IRR) t = Cost ∑CF t /(1 + IRR) t = Cost Decision Rule: Accept if IRR > r (opportunity cost of capital). Decision Rule: Accept if IRR > r (opportunity cost of capital). Non-normal projects have multiple IRRs. Don’t use IRR to decide on non-normal projects. Non-normal projects have multiple IRRs.

Mutually exclusive: select Falafel; higher IRR.

21. Comparison of NPV & IRR For normal independent projects, all three methods give same accept/reject decision. For normal independent projects, all three methods give same accept/reject decision. NPV > 0 yields IRR > r in order to lower NPV to 0. NPV > 0 yields IRR > r in order to lower NPV to 0. However, these methods can rank mutually exclusive projects differently.

24. Determining NPV/IRR Conflict Range For each year, subtract one project’s cash flows from the other. For each year, subtract one project’s cash flows from the other. If there is a change of signs of these cash flow differences, a ranking conflict exists. If there is a change of signs of these cash flow differences, a ranking conflict exists. Find IRR of these cash flow differences to find rate where the two projects have the same NPV = crossover rate. Find IRR of these cash flow differences to find rate where the two projects have the same NPV = crossover rate. At a cost of capital less than this crossover rate, a ranking conflict between NPV and IRR exists. At a cost of capital less than this crossover rate, a ranking conflict between NPV and IRR exists.

25. Marge’s crossover rate At a cost of capital less than 14.1%, Pretzel has higher NPV but lower IRR = Ranking Conflict. At a cost of capital less than 14.1%, Pretzel has higher NPV but lower IRR = Ranking Conflict. At cost of capital greater than 14.1%, Falafel has the higher NPV and IRR. At cost of capital greater than 14.1%, Falafel has the higher NPV and IRR. Why? Cash flow timing differences in this case. Why? Cash flow timing differences in this case.

34. Investment Timing Sometimes you have the ability to defer an investment and select a time that is more ideal at which to make the investment decision. A common example involves a tree farm. You may defer the harvesting of trees. By doing so, you defer the receipt of the cash flow, yet increase the cash flow.

However, scanner prices are expected to decrease 20% per year. Can purchase a scanner today for $400 that would provide $60 in annual benefits for 10 years.
