Case studies

This case describes the coal-procurement process of a small electric utility. The manager of the production fuel department must decide how much coal to purchase from each vendor and how to allocate the purchased coal among the utility's three coal-burning plants. The situation can be modeled and solved as a linear program. Sensitivity analysis can be used to help formulate a strategy for negotiating with the vendors and to address other special issues.

The director of equipment finance at Burlington Northern Railroad Company must decide if a leveraged-lease proposal is acceptable. The case emphasizes the importance of the lessee's tax status to the value of the lease and how the perception of residual value affects the valuation for both the lessee and lessor. To value the lease properly, the student must identify the relevant cash flows and the appropriate discount rates for those flows.

This case is suitable for graduate-level quantitative analysis, business and government, environment and sustainability, and global economics courses. Students must consider the tradeoffs between continuing to run an old coal-burning plant and purchasing emissions allowances (EAs) versus upgrading to emissions-reducing wet or dry scrubbers. Reducing emissions creates the possibility of selling the plant's surplus EAs (which are likely to increase in price). Choosing a wet or dry scrubber requires considering installation cost and construction time, variable cost, and SO2 removal efficiency. Ideally, the investment should pay back over time, but management believes some net investment could also be justified. For that, however, complete analyses from both economic and environmental perspectives are required. A supplemental spreadsheet is available to accompany the case (UVA-QA-0726X).

Is “Fair Trade” really fair? This case examines the concept, history, and logistics of the Fair Trade movement, specifically for coffee. Fair Trade began as an attempt to ensure farmers received fair compensation for their crops and credit when needed. Fair Trade also provided opportunities to help coffee growers learn best practices and sustainable farming methods (minimal damage to the environment, for example). But Fair Trade had its critics, who claimed that ultimately the farmers did not benefit and that retailers charged more for Fair Trade products and pocketed the difference. This case examines these issues through the eyes of one coffee-drinker who has specifically chosen her caffeine venue because of the Fair Trade designation.

Jane Barrow, CEO of Caprica Energy, must recommend to the board which of three potential “unconventional ” natural-gas development sites in different parts of the United States the company should pursue. The case takes place in January 2011, when the “low-hanging fruit ” of natural-gas production in the United States had essentially been picked. All three of the potential sites (shale, coalbed methane, and tight sands) would require hydraulic fracturing, a process of removing gas that was formerly considered inaccessible by injecting water and chemicals into the ground. Because of emerging concerns about the potential harm “fracking ” can do to drinking water, Barrow must not only analyze which site might be most profitable but also what the potential risks to the environment and area residents might be.

A growing folding carton company is contemplating the replacement of an old machine with a new one. The case challenge is to develop a cash flow forecast and determine the proper discount rate for the machine replacement. In addition to increased capacity and reduced waste, the new machine offers strategic advantages to the firm in its chosen market niche. Issues related to operations are central to appreciating the importance and implications of this capital investment: Operating excellence is a key competitive advantage for this firm. A teaching note and student and instructor Excel spreadsheets are available to accompany the case for instructors.

A midsize community hospital must choose a strategy to compete with an expanding regional rival. The strategy, focused on acquiring patient volume, includes expanding investment into integrated care, setting the reimbursement structure for revenue collection, and moving to a capitation-based payment system. The case presents an evaluation of revenue models to select that which best supports a given business strategy.

This case is designed to introduce a health care audience to financial analysis. It provides a straightforward introduction to hospital financial-statement ratio analysis and hospital operating statistics, so it can also serve to introduce any audience with a business or medical background to hospital finance.

This case and its companion, “Myerson Industries” (UVA-QA-0299), constitute the materials for a negotiating exercise. The exercise is a distributive-bargaining situation surrounding the negotiation of the price for the construction of a building (some minor opportunities exist for creating mutual value).

The managing director of a steel plant faces the decision of how much of each raw material to order for the plant for the following month. Due to lower and upper bounds on the amounts of each raw material in a batch and varying amounts of electricity and time consumed for different raw materials, one can't simply use the cheapest raw material. A linear program and the solver optimization function of Excel will provide the optimal amounts that meet the constraints. Interestingly, the best mixture for a batch is not the best mixture for a monthly plan. Shadow prices indicate the value of relaxing constraints. The typical monthly model from a student will be nonlinear, although it can be written as a linear model. This case provides the basis for an introductory class on linear programming and linear versus nonlinear models.

This case may be taught singly or used as a merger-negotiation exercise with “Daimler-Benz A. G.: Negotiations between Daimler and Chrysler” (UVA-F-1241). Set in February 1998, the case places students in the position of negotiators for the company; their task is to value both firms, assess the potential earnings dilution of a combination, and negotiate a detailed agreement with their counterpart. The case can be used to explore such interesting negotiation issues as determination of a share-exchange ratio, treatment of major stockholders, and structuring a deal. Also, the case and exercise can be used to spark a discussion of acquisition in comparison with strategic alliance, or other less formal models of combination.
