Final Answer:
Conceptually, any under- or overapplied overhead at the end of the year should be allocated among Work in Process Inventory, Finished Goods Inventory and Cost of Goods Sold. Thus, the correct answer is c. Raw Materials Inventory.
Step-by-step explanation:
When dealing with under- or overapplied overhead costs, the adjustment should be allocated among Work in Process Inventory, Finished Goods Inventory, and Cost of Goods Sold. Raw Materials Inventory, however, is not affected by the under- or overapplied overhead at the end of the year.
Work in Process Inventory accounts for partially completed goods, Finished Goods Inventory includes completed products awaiting sale, and Cost of Goods Sold represents the expenses incurred to produce goods sold during the period. These three accounts directly relate to the production process and the eventual sale of goods, thus absorbing the impact of under- or overapplied overhead.
On the contrary, Raw Materials Inventory represents the materials yet to be used in production. Since these materials have not entered the production process, they are not impacted by overhead costs that arise from the manufacturing process's indirect expenses.
Therefore, while under- or overapplied overhead is reconciled and allocated among Work in Process Inventory, Finished Goods Inventory, and Cost of Goods Sold to accurately represent production costs and expenses, Raw Materials Inventory remains unaffected as it pertains to materials yet to be utilized in the manufacturing process.
Thus, the correct answer is c. Raw Materials Inventory.
