"LIFO" stands for
last-in, first-out, meaning that the most recently purchased items are recorded as sold first. From the 1970s, some U.S. companies shifted towards the use of LIFO, which reduces their income taxes in times of
inflation, but since
International Financial Reporting Standards (IFRS) banned LIFO, more companies returned to FIFO. One third of American companies are thought to use LIFO, according to the "Save LIFO Coalition", which argues in favor of the retention of the LIFO method. LIFO is used only in the United States, which is governed by the
generally accepted accounting principles (GAAP). Section 472 of the
Internal Revenue Code directs how LIFO may be used if necessary. The code directs that LIFO may be used "only if the taxpayer establishes" that they have no other way of valuing their inventory. In the FIFO example above, the company (Foo Co.), using LIFO accounting, would expense the cost associated with the first 75 units at $59, 125 more units at $55, and the remaining 10 units at $50. Under LIFO, the total cost of sales for November would be $11,800. The ending inventory would be calculated the following way: The balance sheet would show $4500 in inventory under LIFO. The difference between the cost of an inventory calculated under the FIFO and LIFO methods is called the
LIFO reserve (in the example above, it is $750, i.e. $5250 - $4500). This reserve, a form of
contra account, is essentially the amount by which an entity's taxable income has been deferred by using the LIFO method. In most sets of accounting standards, such as the International Financial Reporting Standards, FIFO (or LIFO) valuation principles are "in-fine" subordinated to the higher principle of
lower of cost or market valuation. In the United States, publicly traded entities which use LIFO for taxation purposes must also use LIFO for financial reporting purposes, but such companies are also likely to report a LIFO reserve to their
shareholders. A number of tax reform proposals have argued for the repeal of LIFO tax provision. ==References==
