  2. Number of units produced.
  3. Number of vendors involved.
  4. Number of parts used.

A company experienced a machinery breakdown on one of its production lines. As a consequence of the breakdown, manufacturing fell behind schedule, and a decision was made to schedule overtime to return manufacturing to schedule. Which one of the following methods is the proper way to account for the overtime paid to the direct laborers?

  1. The overtime hours times the sum of the straight-time wages and overtime premium entirely to manufacturing overhead.
  2. The overtime hours times the sum of the straight-time wages and overtime premium direct labor.
  3. The overtime hours times the overtime premium would be charged to repair and maintenance expense, and the overtime hours times the straight-time wages would be
    treated as direct labor.
  4. The overtime hours times the overtime premium would be charged to manufacturing overhead and the overtime hours times the straight-time wages would be treated as direct labor.

Answer(s): D

Explanation:

Direct labor costs are wages paid to labor that can feasibly be specifically identified with the production of finished goods. Factory overhead consists of all costs, other than direct materials and direct labor, that are associated with the manufacturing process. Thus, straight-time wages would be treated as direct labor; however, because the overtime premium cost is a cost that should be borne by all production, the overtime hours times the overtime premium should be charged to manufacturing overhead.



Many companies recognize three major categories of costs of manufacturing a product.These are direct materials, direct labor, and overhead. Which of the following is an overhead cost in the production of an automobile?

  2. The cost of the tires on each automobile.
  3. The cost of the laborers who place tires on each automobile.
  4. The delivery costs for the tires on each automobile.

Answer(s): A

Explanation:

The cost of small tools used in mounting tires cannot be identified solely with the manufacture of a specific automobile. This cost should be treated as factory overhead because it is identifiable with the production process.

  2. Indirect period costs.
  3. Direct product costs.

Without prejudice to your answer to any other question, assume that cost of goods sold for the current year ended December 31 is 2, 000, 000. Inventory turnover on total inventory for the entity would be

  1. 2.04 times.
  2. 3.54 times.
  3. 4.08 times.
  4. 4.82 times.

Answer(s): C

Explanation:

Inventory turnover is the ratio of cost of goods sold to the average inventory balance. The total average inventory is 490, 000 [(90, 000 BFG + 105, 000 BRM + 220, 000 BWIP + 260, 000 EFG + 130.000 ERM + 175.000 EWIP) - 2]. Hence, total inventory turnover is 4.08 times 2, 000, 000 assumed CGS 1 490, 000 average total inventory).
