Key Lecture Concepts
1. PRODUCT COST AND FIXED MANUFACTURING OVERHEAD
0 Product, or manufacturing, costs are comprised of direct materials, direct labor, variable manufacturing overhead, and fixed manufacturing overhead. The basic difference between absorption and variable costing is the treatment of fixed manufacturing overhead.
* With absorption (full) costing, all costs related to the manufacture of a good are product costs. Therefore, fixed manufacturing overhead attaches to the units being made and is carried in inventory until the product is sold.
* Absorption costing results in the preparation of a traditional income statement.
* Absorption costing is considered GAAP and is acceptable for tax reporting.
* Under variable costing, product cost is comprised solely of variable manufacturing costs. Fixed manufacturing overhead is viewed as a cost of being ready to produce, not
