Requirement

1. Assuming the cost object is an airplane, classify each cost as one of the following: direct material (DM), direct labor (DL), indirect labor (IL), indirect materials (IM), other manufacturing overhead (other MOH), or period cost. What is the total for each type of cost? (Enter amounts in thousands instead of dollars by omitting the $000s. Leave cells blank that do not require numerical inputs.)

- Direct materials are those materials and supplies that are consumed during the manufacture of a product, and which are directly identified with that product.

- Direct labor is production or services labor that is assigned to a specific product, cost center, or work order.

- Manufacturing overhead refers to indirect factory-related costs that are incurred when a product is manufactured.

- Period costs are not directly tied to the production process. Overhead or sales, general, and administrative (SG&A) costs are considered period costs. SG&A includes costs of the corporate office, selling, marketing, and the overall administration of company business.
