Inventory Types
2,Alternative inventory systems
Intermediate Accounting 7 Inventories
A perpetual inventory system provides for a
continuous record of physical quantities in the
inventory,A company using a perpetual system
maintains a continuous record of the physical
quantities in its inventory.
A company using the periodic inventory system does
not maintain a continuous record of the physical
quantities (or costs) of inventory on hand.
Periodic Inventory Systems
Intermediate Accounting 7 Inventories
? Cost of Goods Sold is determined and Inventory
is adjusted to proper balance at period end.
? All purchases of inventoriable merchandise are
recorded in the Purchases account.
? Ending inventory is determined by physical count
of merchandise on hand.
Perpetual Inventory Systems
Intermediate Accounting 7 Inventories
? Cost of Goods Sold is determined and Inventory is
adjusted to proper balance each time inventory is
purchased or sold.
? All purchases of inventoriable goods are recorded
in the Inventory account.

3,Items to be included in inventory
quantities
Intermediate Accounting 7 Inventories
Economic control at the balance
sheet date,and not legal ownership
or physical possession,determines
what items are to be included in the
ending inventory.
Whose Inventory Is It?
Intermediate Accounting 7 Inventories
?Goods in Inventory.
?Goods in Transit.
?FOB Shipping Point,buyer’s inventory from
time of shipment.
?FOB Destination,seller’s inventory until
receipt by buyer.
?Goods on Consignment,inventory of the
consignor,not the consignee.
4,Determination of inventory costs
Intermediate Accounting 7 Inventories
? Price paid or consideration given
? Freight-in
? Receiving
? Unpacking
? Inspecting
? Storage
? Insurance
? Sales and other applicable taxes
Inventory Cost is all expenditures related to inventory
acquisition,preparation,and placement for sale.
Inventory costs
Selling costs,which are not
associated with bringing the
inventory to its existing condition
and location,are never included in
inventory,
Intermediate Accounting 7 Inventories
Interest costs are not included in
the cost of inventory that is
routinely manufactured,
Inventory costs
?Material manufacturing costs which are
related directly or indirectly to the
production of inventory are costs of
inventory.
?Variable manufacturing overhead is
related directly and is always included in
inventory.
?The allocation of fixed manufacturing
overhead is difficult and may be
somewhat arbitrary,the costs incurred
must be traceable to the benefits.

5,Inventory valuation methods
Intermediate Accounting 7 Inventories
? Specific
identification
? First-in,first-
out (FIFO)
? Average cost
? Last-in,first-
out (LIFO)
Specific Identification
Intermediate Accounting 7 Inventories
? 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.
First-in,First-out (FIFO) Method
Intermediate Accounting 7 Inventories
? 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.
Average Cost Method
Intermediate Accounting 7 Inventories
?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.
Last-in,First-out (LIFO) Method
Intermediate Accounting 7 Inventories
? Assigns the most recent historical costs to Cost of
Goods Sold and the oldest costs to Inventory.
? Is used primarily to minimize taxable income.
? Results in differences between Cost of Goods
Sold and Inventory for perpetual inventory versus
periodic inventory.

FIFO Advantages and Disadvantages
Intermediate Accounting 7 Inventories
Advantages
?Corresponds with
physical flow of goods.
?Ending inventory
balance is close to
current replacement cost.
Disadvantages
?Matches older costs with
current revenues.
?Inventory holding gains
and losses are part of gross
profit.
?No income tax deferral.
LIFO Advantages and Disadvantages
Intermediate Accounting 7 Inventories
Advantages
?Matches current costs
with current revenues.
?Excludes inventory
holding gains from gross
profit.
?Income tax deferral.
Disadvantages
?Does not correspond with
the physical flow of goods.
?Potential LIFO liquidation
can draw old costs into cost
of goods sold.
?Ending inventory balance
can be much lower than
current replacement cost.

The lower of cost or market rule requires that a
company write down its inventory to market
value when the inventory’s utility has declined.

Gross Profit Method
Intermediate Accounting 7 Inventories
Intermediate Accounting 7 Inventories
The gross profit method is an
estimation technique to determine
the inventory count...
? when a physical
count is not
practical,and
? as a validity check.
Gross Profit Method Steps
Intermediate Accounting 7 Inventories
① Calculate the historical gross profit rate by dividing the
gross profit (net sales minus cost of goods sold) of the
prior period(s) by the net sales of the prior period(s),
② Estimate current gross profit by multiplying the historical
gross profit rate by net sales for the period.
③ Subtract the estimated gross profit from the actual net
sales to determine the estimated cost of goods sold.
④ Subtract the estimated cost of goods sold from the actual
cost of goods available for sale to determine the estimated
cost of the ending inventory,

Gross Profit Method
Enhancing the Accuracy of the Gross Profit
Method
Intermediate Accounting 7 Inventories
? A company should adjust the gross profit rate for known
changes in the relationship between its gross profit and
net sales.
? A company may use a separate gross profit rate for each
department or type of inventory that has a different
markup percentage.
? A company may use an average gross profit rate based on
several past periods to average out period-to-period
fluctuations.
Retail inventory method
Intermediate Accounting 7 Inventories
A company uses the retail inventory method to
determine the cost of its ending inventory based on
current-period estimates of the profit percentage.
① Determine goods available for sale at cost and retail.
② Determine cost percentage.
③ Determine ending inventory at retail.
④ Determine ending inventory at cost.

valuation of inventory and the
recording of its purchases can
result in errors on the company's
balance sheet and income statement
