Final answer:
The specific identification method is ideal for assigning costs since it directly ties cost to each inventory item, eliminates arbitrary cost allocation, and accurately tracks cost flow.
Step-by-step explanation:
The specific identification method of inventory costing is considered ideal in certain situations because it directly ties the cost of an inventory item to its physical sale. This method makes it possible to precisely match costs with revenues, leading to an accurate representation of Cost of Goods Sold (COGS). However, one of the primary reasons this method is appreciated lies in its ability to eliminate arbitrary cost allocation. There is no need to distribute costs among inventory items, which can otherwise be arbitrary when using methods like FIFO or LIFO. Because costs are tied to specific items, the company can track the actual cost flow of each item they sell.
