Definition of LIFO Layer
LIFO is the 游戏电竞线上外围APP v5.2 acronym for Last-In, First-Out . In the context of inventory , it means that the cost of the most recently purchased units will be the first costs to be matched with the recent sales on the income statement. (The oldest costs will remain in inventory.) When the end of the year quantity of inventory increases, the cost of the recently added units becomes a new layer—another LIFO layer . If the end of the year inventory quantity decreases, LIFO layers are "peeled away" starting with the latest (most recent) layer first. We will illustrate this with the following example.
Example of LIFO Layers
Jay Corp. began operations in 2019 using the LIFO cost flow assumption . It ended the year 2019 with 10 units in inventory at a cost of $20 each. Therefore, its LIFO inventory consisted of one layer (its base layer) having a cost of $200. During 2020 Jay Corp. purchased 100 units at $21 each and sold 95 units. Under the LIFO cost flow assumption, it is assumed that the 95 units sold had the most recent cost of $21 (even if the most recently purchased units were not physically shipped out to customers). The LIFO cost flow assumption results in the cost of the 10 units from 2019 remaining in inventory (10 X $20 = $200) and an additional layer being added in 2020. The 2020 LIFO layer will be the 2020 cost of 5 units (5 X $21 = $105). The LIFO inventory cost at the end of 2020 will be the 2019 LIFO base layer of $200 + the 2020 LIFO layer of $105...for a total LIFO inventory cost of $305.
Next, let's assume that in 2021 Jay Corp. purchased 100 units at $22 and sells 102 units. The LIFO cost flow assumption is that the 102 units sold would consist of the cost of the recently purchased 100 units at $22 plus the cost of 2 units purchased in 2020 at $21 each. In other words, Jay Corp. had to peel away part of the 2020 layer since that was the most recently added layer. This means the LIFO cost of inventory at the end of 2021 will consist of the 2019 LIFO base layer of 10 units at $20 each + the 2020 LIFO layer having 3 units at their 2020 cost of $21 each...for a total LIFO inventory cost at the end of 2021 of $263 ($200 + $63).
If Jay Corp. increases its inventory during 2022 by 4 units at a cost of $22 each, a new 2022 LIFO layer of 4 units will be added. The LIFO cost for the inventory at the end of 2022 will be the following: the 2019 base layer (10 units at the 2019 cost of $20 each) + the 2020 LIFO layer (3 units at the 2020 cost of $21 each) + the 2022 LIFO layer (4 units at the 2022 cost of $22 each).
