Kim Inc. must install a new air conditioning unit in its main plant. Kim must install one or the other of the units; otherwise, the highly profitable plant would have to shut down. Two units are available, HCC and LCC (for high and low capital costs, respectively). HCC has a high capital cost but relatively low operating costs, while LCC has a low capital cost but higher operating costs because it uses more electricity. The costs of the units are shown here. Kim's WACC is 7.5%.

1. Which unit would you recommend?
   1. Since all of the cash flows are negative, the IRR's will be negative and we do not accept any project that has a negative IRR.
   2. Since all of the cash flows are negative, the NPV's cannot be calculated and an alternative method must be employed.
   3. Since all of the cash flows are negative, the NPV's will be negative and we do not accept any project that has a negative NPV.
   4. Since we are examining costs, the unit chosen would be the one that had the lower NPV of costs. Since LCC's NPV of costs is lower than HCC's, LCC would be chosen.
   5. Since we are examining costs, the unit chosen would be the one that had the lower NPV of costs. Since HCC's NPV of costs is lower than LCC's, HCC would be chosen.
   
   
2. If Kim's controller wanted to know the IRRs of the two projects, what would you tell him?
   1. The IRR of each project will be positive at a lower WACC.
   2. There are multiple IRR's for each project.
   3. The IRR of each project is negative and therefore not useful for decision-making.
   4. The IRR cannot be calculated because the cash flows are all one sign. A change of sign would be needed in order to calculate the IRR.
   5. The IRR cannot be calculated because the cash flows are in the form of an annuity.
   
   
3. If the WACC rose to 15% would this affect your recommendation?
   1. Since all of the cash flows are negative, the NPV's will be negative and we do not accept any project that has a negative NPV.
   2. When the WACC increases to 15%, the NPV of costs are now lower for LCC than HCC.
   3. When the WACC increases to 15%, the NPV of costs are now lower for HCC than LCC.
   4. When the WACC increases to 15%, the IRR for LCC is greater than the IRR for HCC, LCC would be chosen.
   5. When the WACC increases to 15%, the IRR for HCC is greater than the IRR for LCC, HCC would be chosen.
   
   
   
   Explain your answer and the reason this result occurred.
   1. The reason is that when you discount at a higher rate you are making negative CFs higher and this lowers the NPV.
   2. The reason is that when you discount at a higher rate you are making negative CFs smaller and this lowers the NPV.
   3. The reason is that when you discount at a higher rate you are making negative CFs smaller thus improving the NPV.
   4. The reason is that when you discount at a higher rate you are making negative CFs higher thus improving the IRR.
   5. The reason is that when you discount at a higher rate you are making negative CFs higher thus improving the NPV.

Abe Simpson’s Historical Aircraft, Inc. (ASHAI) is considering adding a rare World War II B-24 bomber to its collection of vintage aircraft. The plane was forced down in Burma 1942, and it has remained there ever since. Flying a crew to Burma and collecting the wreckage will cost $100,000. Transporting the parts to the company’s restoration facility in Springfield will cost another $35,000. Restoring the plane to flyable condition will cost an additional $600,000 at t0.

ASHAI’s operating costs will increase by $40,000 a year at the end of years 1 through 7. At the end of years 3 through 7, revenues from exhibiting the plane at airshows will be $70,000. At the end of year 7, the plane will be retired. At that time the plane will be sold to a museum for $500,000.

The plane falls into the 7 year MACRS depreciation schedule. ASHAI’s tax rate is 35% and the company’s required return on the project is 12%. Calculate the NPV and IRR of the proposed investment in the plane.

In at least 200+ respond to the following (please include any references used)

Take a look at the following information and answer the question below:

If long-run average costs are constant with respect to output, then you have constant returns to scale.

If long-run average costs rise with output, you have decreasing returns to scale or diseconomies of scale.

If long-run average costs fall with output, you have increasing returns to scale or economies of scale. Every company is trying to reach economies of scale. However, it is not always possible. What are some of the things that could keep a company from reaching economies of scale? Why?
