Dave Kellerman and his crews turned out 20,000 fans during the month–a remarkable feat given that the firm’s manufacturing plant was closed for several days because of storm damage and flooding.
Kellerman was especially pleased with the fact that overall financial performance for the period was favorable when compared with the budget. His pleasure, however, was very short-lived, as Johnson’s general manager issued a stern warning that performance must improve, and improve quickly, if Keller man had any hopes of keeping his job.

Required:
1. Explain the difference between a static budget and a flexible budget.
2. Which of the two budgets would be more useful when planning the company’s cash needs over a range of activity?
3. Prepare a performance report that compares budgeted and actual costs for the period just ended (i.e., the report that Kellerman likely used when assessing his performance).
4. Prepare a performance report that compares budgeted and actual costs for the period just ended (i.e., the report that the general manager likely used when assessing Kellerman’s performance).
5. Which of the two reports is preferred? Should Kellerman be praised for outstanding performance or is the general manager’s warning appropriate? Explain, citing any apparent problems for the firm.
