Inventories
are considered by many companies as a very significant asset. The
inventory accounting involves two major aspects: 1) the cost of
inventory purchased or manufactured needs to be determined and 2) the
cost is retained in the inventory accounts of the company until the
product is sold.

Specific
identification |
Each
item sold and each unit remaining in the inventory are individually
identified |
FIFO (First-in, first-out)
|
The
actual physical flow is irrelevant, the important
thing is that
the flow of costs assumes that the first articles in
entering the inventory are the first to be sold
(cost of
sales) or consumed (cost of production). The
final inventory is made up of the last articles that became part of
inventories. |
LIFO (Last-in, first-out)
|
The
actual physical flow is irrelevant, the important thing is that the
flow of costs assumes that the last articles that became
part of the inventory are the first to be sold
(cost of sales) or
consumed (cost of production). The
final inventory
is comprised of the first articles that became part of inventories.

Weighted
Average |
This
method requires calculating the average unit cost of the goods in the
beggining inventory including the purchases made in the accounting
period. Based
on this average cost per unit is determined both the cost of sales
(production) and the ending inventory of the period. |
