Inventory
What is Inventory?
• Items held for resale in the normal
course of business.
• For a manufacturing firm, a broad
array of production costs is included
as part of the cost of inventory.
• The terms raw materials, work in
process, and finished goods refer to
the inventories of a manufacturing
enterprise.
Inventory Systems
•
Two types of inventory systems which
keep track of how much inventory has
been sold and at what price.
1. Periodic system- requires a physical count
of the inventory periodically, and at the
point of sale only records the sale price.
2. Perpetual system- at point of sale records
selling price and type of item sold.
Example: a bar code scanning system.

Stop and Think
If perpetual inventory
systems have so
many clear
advantages, why
aren’t they used by
all companies?
Whose Inventory Is It?
• Report on the balance sheet inventory
to which the company holds legal title.
• Legal title is not determined by who
has physical custody of the inventory
• Issues that develop:
– Goods that are in transit.
– Goods that are on consignment.
Goods in Transit
FOB Shipping Point
Buyer
Seller
Quality
Produce
Goods being shipped are included in
inventory of buyer while in transit.
Goods in Transit
FOB Destination
Buyer
Seller
Quality
Produce
Goods being shipped are included in
inventory of seller until received by buyer.
Goods on Consignment
• Shipper retains title and includes the
goods in inventory until their sale or
use by the dealer or customer.
• Consigned goods are reported by the
shipper at the sum of:
– The cost of the goods
– The handling costs
– The shipping costs incurred in their
transfer to the dealer or customer.
What Is Inventory Cost?
•
•
Inventory costs comprise of all
expenditures both direct and indirect,
relating to acquisition, preparation, and
placement for sale.
Discounts can change the total inventory
costs.
1. Trade Discounts
•
•
Convert the catalog price to the actual price.
Record inventory at discounted price.
2. Cash Discounts
•
•
Granted for payment of invoices within a limited time
period.
Record inventory using the net method or gross
method.
Cash Discounts- Net Method
• Records inventory net of any purchase
(cash) discounts.
Example:
June 1
Purchased merchandise for $10,000;
Terms of payment: 2/10, n/30;
Assuming a perpetual inventory method,
record the purchase of the inventory and
payment on June 8.

LIFO
Specific Identification Method
• Assigns the actual cost of the asset to
Inventory and Cost of Goods Sold.
• Provides a highly objective method of
matching costs because cost flow
exactly matches physical goods flow.
• Is almost impossible to implement
cost effectively.

Average Cost Method
• Assigns the same average cost to each
unit sold and each item in inventory.
• For periodic inventory, the unit cost is
the weighted average for the entire
period.
• For perpetual inventory, the unit cost
is computed as a moving average,
which changes with each new
purchase of goods.

First-In-First-Out
(FIFO) Method
• Assigns historical unit cost to Cost of
Goods Sold in the order the costs are
incurred.
• Provides a close match between
physical product flow and product
cost flow.
• Results in the same inventory
valuation and Cost of Goods Sold
regardless of whether perpetual or
periodic inventory is used.

Unique Aspects of LIFO
• LIFO liquidation- the effect of cost of goods
sold and net income during periods of rising
prices, when “old” inventory layers are sold.
• Low cost prices are matched with higher
sales prices resulting in a lower than usual
cost of goods sold and a higher net income.
• LIFO conformity rule- in the 1930s Congress
specified that companies who use LIFO for
financial reporting must use LIFO for
income tax reporting as well.
• LIFO Tax effect can be significant over time.
See Exhibit 9-14.
Special LIFO Concerns
• LIFO Layers are created each year when the
number of units purchased exceeds the
number of units sold; a new layer of inventory
is created
• LIFO Reserve is the difference between LIFO
ending inventory and FIFO or other inventory
value. LIFO Reserves should be disclosed with
the Balance Sheet
• Results are that older costs are associated
with Sales in succeeding years, usually
resulting in a lower matched COGS and
misrepresenting the Gross Profit as higher
Practice
• 9-35
• 9-7
• 9-8 & 9
FIFO Advantages and
Disadvantages
Advantages:
• Usually corresponds with physical flow of
goods.
• Ending inventory balance agrees closely
with current replacement cost.
Disadvantages:
• Can cause older costs to be matched with
current revenues.
• Inventory holding gains and losses are
included as part of gross profit.
• Yields higher taxable income in times of
inflation if inventory levels are stable or
increasing.
LIFO Advantages
Advantages:
• Matches current costs with current
revenues.
• Excludes inventory holding gains from
gross profit.
• Yields lower taxable income in times
of inflation if inventory levels are
stable or increasing.
LIFO Disadvantages
Disadvantages:
• Usually does not correspond with the
physical flow of goods.
• Potential LIFO liquidation means old cost in
LIFO layers can be drawn in to cost of
goods sold.
• Ending inventory balance can be much
lower than current replacement cost.
• LIFO liquidation can result in greatly
increased tax payments when inventory
levels decline.
FIFO and LIFO Comparison
Inventory Accounting Change
• If a company changes its method of valuing
inventory, the change is accounted for as a
change in accounting principle.
Average Cost

Lower of Cost or Market
• Accounting Principle of
“Conservatism” applies
• LCM recognizes unrealized decreases
in the value of assets, but not
unrealized increases
• Market Value represents current

Gross Profit Inventory Method
• An estimation technique based on the
relationship between gross profit and
Sales
• Gross Profit percentage is applied to
sales to estimate the COGS
• COGS is then subtracted COGA to
arrive at the estimated inventory
• May be used to estimate missing
inventory, verify counts, or use for
interim statements

Effects of Errors
• Misstated inventory will result in
errors on both the Balance Sheet and
Income Statement
• Multiple amounts may be effected on
the Income Statement
• An error in one period effects the next
• Some errors may self-correct
• See p. 479
Effects of Errors in Recording
Inventory
Correction of Errors
• Depends on when error is detected
• If found in current period,
adjustments can be made to current
accounts and the reported net income
and balance sheet amounts will be
correct.
Cost of Goods Sold
1,000
Inventory
1,000
Correction of Errors
• If found in subsequent period and the
net income of the prior period was
misstated, the correcting entry
qualifies as a prior-period adjustment
and is made to beginning retained
earnings of the subsequent period in
which the error was discovered.

Inventory Turnover
Appropriateness of inventory size and
position can be measured by
calculating the
Inventory Turnover Ratio.
Inventory Turnover:
Cost of Goods Sold ÷ Average Inventory

$ 110
$1,000
($90 + $110)/2
= 10
Inventory Turnover
• The higher the Turnover, the faster a
company is using its inventory, thus
“turning a profit”
• The turnover ratio will be different
based on what inventory method is
used: Fifo vs. Lifo
• With an increased turnover, the
investment needed for a given volume
of business is smaller
Number of Days’ Sales in Inventory
• The average time it takes to turn over
the inventory
• The type of inventory and nature of
business determines what is
acceptable
• Days = 365/Inventory Turnover
Number of Days’ Sales in
Inventory
$1,000
($90 + $110)/2
= 10
365

Number of days’ sales in inventory is
36.5
Practice
• Exercise 9-17
Retail Inventory Method
• Used by retail firms to estimate
inventory value.
• Can be used to estimate inventory
under any valuation assumption.
• Cost amounts and retail amounts are
tracked of the goods that have been
purchased in the period.
• Cost percentage = goods available for
sale at cost/ending inventory at retail
