Final answer:
A factor that does not affect the selection of an inventory costing method is a change in the quantity supplied or a movement along the supply curve for a specific good or service, as it is not directly related to the accounting or inventory management practices.
Step-by-step explanation:
When selecting an inventory costing method, there are various factors that businesses take into consideration to properly account for inventory expense on their financial statements. Inventory costing methods, including First-In, First-Out (FIFO), Last-In, First-Out (LIFO), or Average Cost, are utilized to determine the cost of goods sold and ending inventory balance.
However, not every factor will influence the choice of an inventory costing method. One such factor that does not affect this selection is a change in the quantity supplied or a movement along the supply curve for a specific good or service. This is because such a movement is a price reaction to the current market demand and does not directly relate to the accounting or inventory management practices within a company.
The choice of inventory costing method is more commonly influenced by factors like the nature of the inventory, tax considerations, financial reporting objectives, or inflationary environments.
