Merchandise Inventory
1. Acquisition of inventory: What costs to
capitalize?
2. Recording inventory activity: Which
method?
3. Selling inventory: Which cost flow
assumption?
4. Ending inventory: Lower-of-cost-or market
valuation.

1. Acquiring Inventory

What items or units to include?
– General rule: complete and unrestricted
ownership.

Acquiring inventory - contd.

Which costs are included in inventory?
– General rule: all costs associated with purchase or
manufacture, including shipping to facility.
– Freight-in (transportation-in) adds to the
cost of inventory.
– Purchase returns reduce the cost of
purchases (contra) for returned inventory.
– Purchase allowances reduce the cost of
purchases (contra) for reduced prices due to
damage or errors.
– Purchase discounts from early cash
payments (contra) reduce the cost of
purchases.

Assume that counting errors caused the
ending inventory (EI) in 2007 to be
understated by $50 and the ending
inventory in 2008 to be overstated by $50.
Compute the impact of these errors on cost of
goods sold for the year ended December 31,
2007 and on the inventory balance as of
December 31, 2007.

E7-6
a. Error in Ending Inventory in 2007: The
$50 understated error in the Ending
inventory means that the Ending Inventory
should have been $268 + $50 = $318. This
would change the Cost of goods sold to
$1,174 - $318 = $856 which would then
increase the Gross profit to $421 ($1,277 $856).

b.
Error in Ending Inventory in 2008: =
The 2007 error in the Ending Inventory
changes the Beginning Inventory in 2008
and the Goods Available for sale to $318 +
$857 = $1,175. To calculate the Cost of
Goods Sold the Ending Inventory for 2008 is
deducted from the revised Goods Available
for Sale: $1,175 – ($239 - $50) = $986. The
gross profit would then be $1,262 - $986 =
$276.

3. Cost Flow Assumptions
Given: BI + P (net) = EI + COGS
 How to assign costs of inflows [BI +
P(net)] to EI and COGS?
Methods:
 Specific identification
 Average for both COGS and EI
 FIFO - (first-in, first-out) for COGS

– and LISH (last-in, still here) for EI

LIFO - (last-in, first-out) for COGS
– and FISH (first-in, still here) for EI
16
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.

– Debt and Compensation Practices
– The Capital Market
24
Ending Inventory: Applying the Lower-of-Cost-orMarket Rule

Applying the lower-of-cost-or-market rule to
ending inventory is accomplished by comparing
the cost allocated to ending inventory with the
market value of the inventory. If the market value
exceeds the cost, no adjustment is made and
the inventory remains at cost. If the market value
is less than the cost, the inventories are written
down to market value with an adjusting journal
entry.
25
The Lower-of-Cost-or-Market Rule
and Hidden Reserves

Based on conservatism, ending inventory is
valued at cost or market value, whichever is
lower.
 Problem: can create hidden reserves
– Recognizes price decreases immediately
– Defers price increase recognition until sold

US GAAP and IFRS use different market
values when applying the lower-of-cost-ormarket rule. Under US GAAP the market
value is usually the replacement cost. Under
IFRS it is normally the realizable value.
26
International Perspective: Japanese
Business and Inventory Accounting

Just-in-time (JIT) inventory systems, which
reduce the costs of carrying large amounts of
inventory without jeopardizing customer
service, have long been a characteristic of
this Japanese system and have given the
Japanese a definite advantage when
competing against U.S. industry.
 Japan has adopted international reporting
standards (IFRS), which does not allow the
use of LIFO.
