Sue Gorman is the daughter of Fred Gorman, the founder and president of Big Sky Enterprises. She has been working in various departments during school vacations throughout high school. She burst into the accounting department excitedly one morning. She said that the stock price of several of the firm's short-term investments are up, and that her father said that the company had made over $10,000 because of this jump in stock prices. She asks to see how the increase is recorded. It is a very busy time in the accounting department, and so her question is deferred.
