The inventory has to be recorded separately to each item and this will generally result in the lowest inventory amount.
Explanation:
LCM- the Lower of Cost which is also called as Market rule is the theory for valuating the inventory in accounting. According to the LCM rule, in a business the cost of inventory must be recorded at lower cost (it can be either the current market price or the original cost)
Reason for recording at lower cost:
Aggregating the items results in the incorporation of some items at amounts greater than LCM.
Example:
If product X (cost = 2 dollars, market = 1 dollar) and product Y (cost = 3 dollars, market = 4 dollars) are aggregated for LCM, the inventory measurement will be 5 dollars. If the rule is applied separately to both the products, the LCM measurement will be 4 dollars.
