Shimizu Corporation, a Japanese construction company, has been selected as the prime contractor to build a gymnastics arena for use in the Tokyo 2020 Olympic Games. Based on company cost estimates, the project provides a 7.4% return on costs, well below the company's required 8% for projects of this size and scope. A senior officer in the company is charged with reviewing the proposed terms of the contract and either accepting or suggesting new terms. This case can be used as an introduction to or a reinforcement of discounted-cash-flow techniques. It provides a dramatic portrayal of the time value of money, an opportunity for sensitivity analysis, and a possibility for using decision diagrams for structuring realistic contingencies.
