Inventory Valuation and Consequences
 Same total $$ amount over the life of the company is allocated differently to
cost of goods sold and ending inventory.
•
•
Is Cost of Goods Sold Correct?
Is Ending Inventory Correct?
•
Income and Asset Measurement
– How much does it cost?
– Valuation: Cost-original or replacement, Lower of Cost or Market
•
Economic Consequences
– Income Taxes and Liquidity
– Bookkeeping Costs
– LIFO Liquidation and Inventory Purchasing Practices
– Debt and Compensation Practices
– The Capital Market- Current ratio, Profit margin ratio

Summary of LIFO, FIFO, Average cost
• Managers have wide latitude in inventory cost flow
decisions. Specific identification is generally
considered appropriate where items of inventory are
unique (low volume, high cost items) because of the
potential for income manipulation.
• LIFO is generally used when prices are rising
because of the tax advantages and the requirement
that it be used in the financial statements if it is used
for tax purposes.
• The only theoretical defense for LIFO is that in times
of extreme inflation, it minimizes the inflationary
distortions in the income statement by matching
current dollars of revenues and expenses. However,
the LIFO method, over time, misrepresents the
balance sheet by understating inventory values.
Summary of FIFO, LIFO, Average cost
• If a company adopts LIFO, it must disclose in its footnotes
the “LIFO reserve” which is the difference between ending
inventory ‘s FIFO value and LIFO value.
• FIFO’s advantage is that it provides a valuation for ending
inventory that more closely approximates its current
replacement cost. FIFO’s disadvantage is that it does not
provide a good match of revenues and expenses in
current dollars during periods of changing prices.
• Weighted average is a good compromise in that it
generally provides a fairly good match of revenues and
expenses as long as inventory is turning over fairly fast
which keeps inventory levels fairly low. In such cases, it
will tend to give an inventory value on the balance sheet
that is closer to FIFO, since current purchases normally
have more influence than beginning inventories on
determining the average cost.
LIFO to FIFO Inventory
Conversion
• The difference between LIFO and FIFO inventory
values is called the “LIFO Reserve.”
• Assuming prices rise over time, the effect on the
balance sheet of using LIFO is that assets and
shareholders’ equity (Retained Earnings) are
lower than they would be under FIFO.
• The reduction is not equal to the LIFO reserve
because of tax consequences. Inventory values
may be lower but cash is higher by the amount of
the LIFO reserve times the tax rate.
• Thus, total assets are lower by the LIFO reserve
times (1-tax rate) and Retained Earnings is lower
by the LIFO reserve times (1-tax rate).
FIFO V. LIFO
General Electric uses LIFO inventory cost
flow assumption, reporting inventories on its
2012 balance sheet of $15.4 billion and a
LIFO reserve of approximately $398 million.
What would be GE’s 2012 inventory balance
if it used FIFO assumption instead?
Why is disclosure of the LIFO reserve useful
to financial statement users?
International Perspective – Cost Flow
Assumptions
• Under IFRS the LIFO method is prohibited.
• This poses an important potential impediment to
the adoption of IFRS in the US. Most LIFO
users in the US have chosen LIFO because it
results in an income tax savings.
• DuPont, for example, has saved over $150
million in income taxes because it uses LIFO.
• A shift to IFRS could impose a huge and
immediate tax burden on LIFO users in the US.
LIFO Liquidation and Hidden Reserves
In the early 1980s, an oil glut caused Texaco, a
LIFO user, to delay drilling, which cut it oil
inventory levels by 16%. The LIFO cushion
(i.e., the difference between LIFO and FIFO
inventory values) that was built into those
barrels over the year amounted to $454 million
and transformed what would have been a drop
in net income to a modest gain.
Explain how using LIFO could be interpreted as
building “hidden reserves.”
Dollar-value LIFO
 Lose verifiability
• BUT
 Reduce cost of measurement
Dollar-value LIFO
 Periodic
• Determine ending inventory (EI)
• Use EI to determine COGS
 Ending Inventory
• Need ‘units’
 Inventory in base-year dollars
• Need ‘cost’ per ‘unit’
 Price index
