• The cost of the newest inventory items remain in ending inventory.

When Prices Are Rising . . .

LIFO• Matches high (newer)

costs with current (higher) sales.

• Inventory is valued based on low (older) cost basis.

• Results in lower taxable income.

FIFO• Matches low (older)

costs with current (higher) sales.

• Inventory is valued at approximate replacement cost.

• Results in higher taxable income.

8 - 36

U. S. GAAP vs. IFRS

• LIFO is permitted and used by U.S. Companies.

• If used for income tax reporting, the company must use LIFO for financial reporting.

• Conformity with IAS No. 2 would cause many U.S. companies to lose a valuable tax shelter.

• IAS No. 2, Inventories, does not permit the use of LIFO.

• Because of this restriction, many U.S. companies use LIFO only for domestic inventories.

LIFO is an important issue for U.S. multinational companies. Unless the U.S. Congress repeals the LIFO conformity rule, in inability to use LIFO under IFRS will

impose a serious impediment to convergence.

Decision Makers’ Perspective

Factors Influencing Method Choice

How are income taxes affected by inventory method

choice?

How closely do reported

costs reflect actualflow of inventory?

How well are costs matched against

related revenues?

LIFO Liquidation

LIFO inventory costs in the balance sheet are “out of date” because they

reflect old purchase transactions.
