Inventory Classification
• Inventory is classified as a current asset
• A merchandising company:
– has one inventory account on the balance sheet
called Merchandise Inventory;
– the cost of the inventory sold is transferred to Cost of
Goods Sold (COGS) on the income statement
• A manufacturing company:
– will normally have three inventory accounts on the
balance sheet: raw materials, work in process and
finished goods;
– Cost of Goods Manufactured (COGM) is used by a
manufacturer which is similar to the COGS

Inventory
• Definition of Inventory:
Inventories are “assets:
(a) held for sale in the ordinary course of
business;
(b) in the process of production for such sale; or
(c) in the form of materials or supplies to be
consumed in the production process or in
the rendering of services.”
Copyright © John Wiley & Sons Canada, Ltd.
7
Items to Be Included in Inventory
• Legal title to goods generally determines
items to be included in inventory
• The following goods are included in the
seller’s inventory:
1. Goods in transit (if seller has title during
shipment, i.e., if shipped f.o.b. destination)
2. Goods out on consignment
3. Goods sold under buyback agreements
4. Goods sold with high rates of return that
cannot be estimated

December 31st inventory errors both discovered after
2014 books were closed:
2013: inventory overstated by $110,000
2014: inventory overstated by $45,000
Calculate correct 2014 COGS and R/E at Dec. 31,
2014

Costs Included in Inventory
• Inventory cost includes “all costs of purchase,
costs of conversion, and other costs incurred in
bringing the inventories to their present location
and condition”
• These costs include:
– Product costs including invoice, freight, and other
direct acquisition costs
– Conversion costs which include direct labour and
fixed and variable overhead
• Period costs (selling, general, and
administrative) are not inventoriable costs
Copyright © John Wiley & Sons Canada, Ltd.
12
Costs Included in Inventory
Other issues to consider:
• Purchases discounts: gross method vs. net
method
• Vendor rebates: cash rebates related to
inventory generally recorded as a reduction to
the cost of inventory
• “Basket” purchases and joint product costs:
total cost allocated to units based on relative
sales value
Copyright © John Wiley & Sons Canada, Ltd.
13
Costs Included in Inventory
Interest or borrowing costs
• Under IFRS, interest costs are included as
product costs if manufacturing of inventory takes
a long time (otherwise, company has a choice
whether to capitalize interest costs or not)
• Under ASPE, interest costs may be either
capitalized or expensed, but policy must be
disclosed.
Copyright © John Wiley & Sons Canada, Ltd.
14
Purchase Commitments
• Where a company commits to purchase
inventory, but title has not passed to the buyer
• Non-cancellable purchase contracts are not
recorded, but if material, they are disclosed in
the notes to the financial statements
• Loss provision is recognized on onerous
contracts (even though no specific requirement
under ASPE)
– Onerous contracts are contracts where unavoidable
costs to complete the contract are higher than
expected benefits
Copyright © John Wiley & Sons Canada, Ltd.
15
Inventory Accounting Systems
• An accurate inventory accounting system is
important for:
-
ensuring availability of inventory items
preventing excessive accumulation of
inventory items
• Just-in-time (JIT) inventory order systems have
helped reduce inventory levels
• The perpetual system maintains a continuous
record of inventory changes
• The periodic system updates inventory records
in the ledger only periodically
Copyright © John Wiley & Sons Canada, Ltd.
16
Perpetual System
• Purchases of inventory and cost of inventory sold are recorded
directly in the Inventory account
• Cost of freight, purchase returns and allowances, and purchase
discounts are all recorded in the Inventory account
• Cost of Goods Sold (COGS) is debited and Inventory is credited
when inventory is sold
• A subsidiary ledger is maintained for individual inventory items on
hand
• Periodic inventory counts are still required to ensure reliability
• Any differences between the inventory balance and the physical
count are captured in a separate account called Inventory Over and
Short (or may be recorded as an adjustment to Cost of Goods Sold)
Copyright © John Wiley & Sons Canada, Ltd.
17
Periodic System
• Inventory purchases are recorded as a debit to a Purchases account
• Cost of Goods Sold and Inventory accounts are not kept up to date
• The quantity and cost of inventory on hand is determined by taking a
physical inventory count
• Cost of Goods Sold is determined at the end of the period
• Under both periodic and perpetual inventory systems, physical
counts of inventory are conducted at least once a year as there is
the risk of loss and errors (e.g. waste, breakage, theft)
• Freight, purchase returns and allowances, and purchase discounts
are recorded in separate accounts
Copyright © John Wiley & Sons Canada, Ltd.
18
Perpetual and Periodic Systems:
Example
Fesmire Limited reports the following data:
Beginning Inventory :
Purchases: (all credit)
Defective units (returned)
Sales: (all credit)
Ending Inventory:
100 units at $6
900 units at $6
50 units at $6
600 units at $12
350 units at $6
Provide all journal entries under each system.

Cost Formulas
IFRS and ASPE recognize three acceptable
cost formulas:
1. Specific identification
2. First-in, First-out (FIFO)
3. Weighted average cost
Copyright © John Wiley & Sons Canada, Ltd.
22
Cost Formulas
• The ending inventory in units is the same
in all three methods; the cost is different
• The cost of goods sold and the cost of
ending inventory are different
• The cost of purchases is the same in all
three methods
Copyright © John Wiley & Sons Canada, Ltd.
23
Specific Identification
• Each item sold and purchased is individually identified
• Required for goods that are not ordinarily
interchangeable; and that are produced and segregated
for specific projects
• Advantages:
– Matches actual costs with revenue
– Ending inventory reported at specific cost
• Disadvantages:
– May be costly to implement and maintain
– May lead to income manipulation
– May be difficult to allocate certain costs (e.g., storage, shipping)
to specific inventory items
Copyright © John Wiley & Sons Canada, Ltd.
24
Weighted Average Cost
• Justification for using weighted average cost formula:
– Reasonable to cost inventory based on an average cost
– Costs assigned closely follows the actual physical flow
– Simple to apply, objective, less subject to income manipulation
– Ending inventory cost on balance sheet is made up of average
costs
• Moving-average cost formula refers to a weightedaverage method used with perpetual records (both units
and dollars)
Copyright © John Wiley & Sons Canada, Ltd.
25
First-In, First-Out (FIFO)
Advantages:
– Attempts to approximate physical flow of goods
– Ending inventory made up of most recent costs, therefore close
to its replacement cost
– Does not permit manipulation of income
Disadvantages:
– Current costs not matched to current revenues, as oldest cost of
goods are used with current revenue
– When prices are changing rapidly, gross profit and net income
are distorted
Copyright © John Wiley & Sons Canada, Ltd.
26
Choice of Cost Formula
• Inventory standards limit the choice of cost
formula
• Specific identification is required in some cases
• Should choose the best method that:
1. best reflects the physical flow
2. reflects the most recent costs in the inventory
account, and
3. use this method for all inventory assets with same
characteristics
Copyright © John Wiley & Sons Canada, Ltd.
27
Cost Formulas
• LIFO is not acceptable because:
1. LIFO does not represent actual inventory
flows reliably
2. Costs assigned to ending inventory (oldest
costs) do not represent recent cost of
inventory on hand
3. Can distort reported income on the income
statement
• LIFO has never been allowed by CRA

Basic Valuation Issues
• Most inventory is valued using a cost-based system at
“lower of cost and net realizable value”
• Specialized inventory (e.g. biological assets, including
plants and animals) may use a “net realizable value”
model (or “fair value less cost to sell”)
• Under the typical cost-based system, ending inventory
valuation requires answers to each of the following:
1. Which physical goods should be included as part of inventory?
2. What costs should be included as part of inventory cost?
3. What cost formula should be adopted?
4. Has there been an impairment in value of inventory items held?
Copyright © John Wiley & Sons Canada, Ltd.
33
Lower of Cost and NRV
• Inventory is initially recorded at cost
• Inventory is valued at the lower of cost and
net realizable value (LC&NRV)
• Net realizable value (NRV) is the
estimated selling price less the estimated
costs to complete and sell
Copyright © John Wiley & Sons Canada, Ltd.

35
Recording the LC&NRV
Under the Direct Method:
– The Inventory account is recorded at its net
realizable value at year end if the NRV is less
than cost
– Loss becomes part of cost of goods sold on
the income statement

Exceptions to the LC&NRV Model
• Inventories measured at Net Realizable Value if:
– Sale is assured, or there is active market and minimal
risk of not completing the sale, and
– Costs of disposal can be estimated
• Inventories measured at Fair Value Less Cost to
Sell include
– Inventories of commodity broker-traders
– Biological assets and agricultural produce at point of
harvest
• There is no specific ASPE guidance on measurement of
these assets
Copyright © John Wiley & Sons Canada, Ltd.
40
Gross Profit Method of Estimating
Inventory
• Gross profit method is used to estimate ending
inventory
• Estimates may be required in such situations:
interim reporting, fire loss, testing reasonableness of
cost from an actual inventory count
• Method is based on the three assumptions:
Beginning inventory + purchases = cost of goods
available for sale
2. Goods not sold are in ending inventory
3. Cost of goods available for sale – cost of goods sold
= ending inventory
1.
Copyright © John Wiley & Sons Canada, Ltd.
41
Gross Profit Method: Example
Given:
•
•
•
•
Beginning inventory (at cost): $ 60,000
Purchases (at cost) :
$ 200,000
Sales (at selling price) :
$ 280,000
Gross profit percentage on sales:
30%
• Estimate the ending inventory using the gross
profit method
Copyright © John Wiley & Sons Canada, Ltd.
42
Gross Profit Method: Example
Beg. Inventory + Purchases – COGS = Estimated Ending
Inventory
Cost of goods sold = Sales x (1 - 0.3) = Sales x 70%
$60,000 + $200,000 - ($280,000x0.7) = Ending Inventory
$60,000 + $200,000 - ($196,000)= $64,000
Copyright © John Wiley & Sons Canada, Ltd.
43
Understanding Markups
• Assume you are given markup on cost
• What is gross profit on selling price?
• Assume markup on cost is 25%
Cost + Gross Profit = Sales ==> C + 25%C = Sales
Cost of goods sold (1 + 25%) = Sales
Cost of goods sold = Sales x (1/1.25)
Gross Profit
= Sales x (.25/1.25)
If Sales is $1, Gross profit % = $1 x (.25/1.25) = 20%
Gross Profit % = Markup % / (1 + markup %)0
Copyright © John Wiley & Sons Canada, Ltd.
44
Disclosure and Presentation
•
Examples of required disclosures:
1. Measurement policy
2. Total inventory, as well as inventory by classification
3. Amount of inventory recognized as expense on the
income statement (usually reported as cost of goods
sold)
4. Any amount of inventory pledged as security for
liabilities
•
IFRS has more disclosure requirements than
ASPE

Comparison of IFRS and ASPE
• Major different between IFRS and ASPE
relates to a specific IFRS standard
covering biological assets and agricultural
produce at the point of harvest
• ASPE has no specific guidance in this
area

47
Looking Ahead
• No major changes are expected in the
standards
