What is a FIFO layer?

When an organization uses FIFO or LIFO costing methods, inventory costs are maintained in layers, each with its own costs. The cost flows of FIFO and LIFO are opposite. In FIFO valuation, the earliest-received stock is assumed to be used first; the latest-received stock is assumed to be still on hand.

How do you find the LIFO layer?

Determine any incremental increases in units of inventory in the next reporting period. Calculate the extended cost of these incremental units at base year prices. Multiply the extended amount by the conversion price index. This yields the cost of the LIFO layer for the next reporting period.
