Question: The four underlying assumptions of generally accepted accounting principles are economic entity, monetary unit, periodicity, and going concern. Consider the four independent situations below

1. McAdam's is a local restaurant. Due to a bad shipment of potatoes, several of the company's customers become ill, and the company receives considerable bad publicity. Revenues are way down, several of its bills are past due, and the company is making plans to close the restaurant at the end of the month. The company continues to report its assets in the balance sheet at historical (original) cost.

2. Uncle Sam's Tax Services is owned and operated by Sam Martin. The company has the usual business assets: land, building, cash, equipment, and supplies. In addition, Sam decides to buy a boat for him and his family to enjoy on the weekends. Sam includes the boat as an asset on the balance sheet of Uncle Sam's Tax Services.

3. Tison International, a U.S.-based company, has operations in the United States and in Europe. For the current year, the company purchased two trucks in the United States for $10,000 and three trucks in Europe for €20,000 (euros). Because of the differences in currencies, the company reported "Five Trucks" with no corresponding amount in the balance sheet.

4. Trumpets Etc. sells specialty music equipment ranging from African bongo drums to grand pianos. Because of the fluctuating nature of the business, management decides to publish financial statements only when a substantial amount of activity has taken place. Its last set of financial statements covered a period of 14 months, and the set of financial statements before that covered a period of 18 months. Required:
For each situation, indicate which of the underlying assumptions of GAAP is violated.
