The yield to maturity on one-year zero-coupon bonds is currently 7 percent; the YTM on two-year zeroes is 8 percent. The federal government plans to issue a two-year-maturity coupon bond, paying coupons once per year with a coupon rate of 9 percent. The face value of the bond is $100.

  1. At what price will the bond sell?
  2. What will be the yield to maturity on the bond?
  3. If the expectations theory of the yield curve is correct, what is the market expectation of the price that the bond will sell for next year?
  4. If the liquidity preference theory is correct and you believe that the liquidity premium is 1 percent, what is the market expectation of the price that the bond will sell for next year?

You have been hired to design a spring-launched roller coaster that will carry two passengers per car. The car goes up a 12-m-high hill, then descends 20m to the track's lowest point. You've determined that the spring can be compressed a maximum of 2.5m and that a loaded car will have a maximum mass of 450kg . For safety reasons, the spring constant should be 15% larger than the minimum needed for the car to just make it over the top.

A) What spring constant should you specify?

B) What is the maximum speed of a 360kg car if the spring is compressed the full amount?

Mini Case #1: Capital Budgeting at Rio Negro, Inc.

Assignment Overview Rio Negro, Inc.

(RNI) is in the business of transporting cargo between ports in California and Washington. Its fleet includes a small dry-cargo vessel, the Maracas. The Maracas is 25 years old and badly in need of an overhaul. It is March 2016, and Michael John, the finance director, has just been presented with a proposal that would require the one-time expenditures shown below in Table 1. If the proposal is accepted, these expenditures will be made in the next few days. Mr. John believes that all these outlays could be depreciated for tax purposes in the seven-year MACRS class (see Table 2 below for rates). Overhaul of the Maracas will begin as soon as the expenditures in

Table1 are made, but the vessel will be out of service for several months. The overhauled vessel would resume commercial service in one year. RNI’s chief engineer’s estimates of the post-overhaul operating costs are in

Table 3. In addition to the overhaul described above, the chief engineer suggests installation of a brand- new engine and control system. Installation of this new engine would cost an extra $600,000 (This additional outlay would also qualify for tax depreciation in the seven-year MACRS class.). However, if the additional equipment is installed, it would result in reduced fuel, labor, and maintenance costs as shown in

Table 4. The operating cost estimates in Tables 3 and 4 are current for March 2016. However, these costs will increase with inflation, which is forecasted at 1.25% a year. Depreciation and operating costs attributable to the overhaul of the Maracas will begin one year after the vessel is put back into commercial service. The revenues from operating the vessel will be the same for both types of overhaul. Even with the proposed overhaul, the Maracas cannot continue forever. After the overhaul, its remaining useful life is estimated to be only 12 years. Its salvage value when finally taken out of service will be trivial. Thus, Mr. John feels it is unwise to proceed without also considering the purchase of a new vessel. Racette & Sons (R&S), a Colorado shipyard, has approached RNI with a design incorporating a Kort nozzle, extensively automated navigation and power control systems, and much more comfortable accommodations for the crew. R&S is offering the new vessel for a fixed price of $3,000,000, payable half immediately and half on delivery in one year. Estimated annual operating costs of the new vessel are in Table 5. The operating cost estimates in the table are current for March 2016, but will increase with inflation. The crew would require additional training to handle the new vessel’s more complex and sophisticated equipment. Training would result in a one-time cost of $50,000 payable one year following delivery of the new vessel. This cost is tax deductible. The estimated operating costs for the new vessel assume that it would be operated in the same way as the Maracas. However, the new vessel will be able to handle a larger load on some routes, which is expected to generate additional revenues of approximately $175,000 per year in the first year of operation. These revenues are expected to grow at the rate of inflation. Revenues and operating costs from the new vessel will begin one year after it is delivered. The new vessel is estimated to have a useful service life of 20 years, but it will be depreciated for tax purposes according to the 7-year MACRS schedule. The new vessel is not expected to have any resale value at the end of its 20-year useful life. All revenues and costs (including depreciation) associated with the new vessel will begin one year after it is delivered. The Maracas is carried on RNI’s books at a book value of only $100,000 and the book value of the spare parts is $40,000. The Maracas could probably be sold now “as is,” together with its extensive inventory of spare parts, for $200,000. Mr. John stepped out on the foredeck of the Maracas as she chugged down the Cook Inlet. “A rusty old tub,” he muttered, “but she’s never let us down. I’ll bet we could keep her going until next year while Racette & Sons are building her replacement. We could use up the spare parts ($40,000) to keep her going and we should even be able to sell or scrap her for book value when her replacement arrives.” RNI evaluates capital investments of this type using a 8.5% cost of capital. (This is a nominal, not real, rate.) RCI’s tax rate is 35%.

Any other aids are unauthorized and their use constitutes a violation of academic integrity.

1. Introduction

2. Analysis

3. Conclusion

The introduction sets the stage for the work to follow and should consist of a short paragraph of the key problem(s) or issue(s) that your analysis addresses. The analysis will constitute the bulk of the written presentation and will be a direct response to the questions below. Use clear, concise, and complete sentences. Do not use bullet points or numbered paragraphs. The conclusion should be a short paragraph that summarizes the key points of the analysis. Your report should not exceed five pages of double-spaced text with 1 inch margins at the sides, top, and bottom of the page. This does not include exhibits of your computations. You may submit one Excel Spreadsheet that contains all your exhibits, clearly labeled, and appropriately referenced in the text of your report. Your analysis of “Rio Negro, Inc.” should consist of answers to the questions below. Do not write the questions verbatim in your report. Instead, write a brief introductory statement that summarizes the question before you proceed with your analysis.

4. Calculate the present value of the proposed overhaul of the Maracas, with and without the new engine and control system. Should RNI do the basic overhaul or the expanded overhaul with the new engine and control system? For the moment, ignore the option to purchase a new vessel (you will evaluate that option in question 2 below). Write a few paragraphs giving your answer and clearly explaining your reasoning and computations; show detailed computations in your Excel spreadsheet labeled Exhibit 1.

5. Calculate the present value of buying and operating the new vessel. What, if any, additional information would be useful to you in your analysis? Write a few paragraphs giving your answer and clearly explaining your reasoning and computations; show detailed computations in your Excel spreadsheet labeled Exhibit 2.

6. Calculate the equivalent annual costs of (a) overhauling and operating the Maracas for 12 more years (with and without the new engine and control system) and (b) buying and operating the proposed replacement vessel for 20 years. You should use the real discount rate for this analysis. Based on your answer, what should RNI do? Write one to two paragraphs giving your answer and clearly explaining your reasoning and computations; show detailed computations in your Excel spreadsheet labeled Exhibit 3.

7. Why is the equivalent annual cost method potentially useful in decision making in this case? Why would you use the real discount rate to compute the EAC? What problem(s) do you see with using the equivalent annual cost method to evaluate RNI’s options? One to two paragraphs. Your report is intended for the senior management of Rio Negro, Inc., so be sure that you write in a professional style that is easy to follow.

Can you please answer question 5 only? Thanks!
