Final answer:
CEO and other executive salaries are administrative expenses, not a direct product cost like direct materials, direct labor, or manufacturing overhead.
Step-by-step explanation:
The three general categories of product costs are direct materials, direct labor, and manufacturing overhead. CEO and other executive salaries are not considered a direct part of product cost; instead, they are typically categorized as administrative expenses or part of the general and administrative costs of running a business. In accounting, product costs are usually associated with manufacturing and the costs incurred to create a product, whereas CEO and executive salaries are not tied directly to the production of individual products.
