1. A salaried production supervisor is given a raise, but no adjustment is made in the labor cost standards.

2. The materials purchasing manager gets a special reduced price on raw materials by purchasing a train carload. A warehouse had to be rented to accommodate the unusually large amount of raw materials. The rental fee was charged to Rent Expense, a fixed overhead item.

3. An unusually hot August caused the company to use 30,000 kilowatts more electricity than provided for in the variable overhead standards.

4. The local electric Utility company raised the charge per kilowatt-hour. No adjustment was made in the variable overhead standards.

5. The plant manager traded in his leased company car for a new on in July, increasing the monthly lease payment by $85.

6. A machine malfunction on the assembly line (caused by using cheap and inferior raw materials) resulted in decreased output by the machine operator and higher than normal machine repair costs. Repairs are treated as variable overhead costs.

7. The production maintenance supervisor decreased routine maintenance checks, resulting in lower maintenance costs and lower machine production output per hour. Maintenance costs are treated as fixed costs.

8. An announcement that vacation benefits had been increased resulted in improved employee morale. Consequently, raw materials pilferage and waste declined, and production efficiency increased.

9. The plant manager reclassified her secretary to administrative assistant and gave him an increase in salary.

10. A union contract agreement calling for an immediate 4 percent increase in production worker wages was signed. No changes were made in the standards.
