DETERMINING INVENTORY ITEMS
Merchandise inventory includes all goods that a
company owns and holds for sale, regardless of where
the goods are located when inventory is counted.
Items requiring special attention include:
Goods in
Transit
Goods on
Consignment
Goods
Damaged or
Obsolete

GOODS ON CONSIGNMENT
Merchandise is included in the inventory of the
consignor, the owner of the inventory.
Consignee
Thanks for selling my
inventory in your
store.
Consignor
6-5
C1
GOODS DAMAGED OR OBSOLETE
Damaged or obsolete goods are not counted in
inventory if they cannot be sold.
Cost should be reduced to net realizable
value if they can be sold.
Net realizable value is the estimated
selling price in the ordinary course of
business less the estimated costs of
completion and the estimated costs
necessary to make the sale.

INTERNAL CONTROLS AND TAKING A
PHYSICAL COUNT
 Most companies take a
physical count of
inventory at least once
each year.
 When the physical count
does not match the
Merchandise Inventory
account, an adjustment
must be made.
Good internal controls over count include:
1. Pre-numbered inventory tickets.
2. Counters have no inventory responsibility.
3. Counts confirm existence, amount, and
quality of inventory item.
4. Second count is taken.
5. Manager confirms all items counted.

INVENTORY COST FLOW ASSUMPTIONS
Management decisions in accounting for inventory
involve the following:
1. Items included in inventory and their costs.
2. Costing method (specific identification, FIFO, or
weighted average cost).
3. Inventory system (perpetual or periodic).
4. Use of market values or other estimates.
LIFO is not allowed under IFRS.

Specific
Identification
When each item can be
identified with a specific
purchase
First-In, First-Out
(FIFO)
Assumes costs flow in the order
incurred.
Weighted
Average Cost
Assumes costs flow at an
average of the costs available.

OF COSTING METHODS
Because prices change, inventory methods nearly always
assign different cost amounts.

CONSISTENCY IN USING
COSTING METHODS
A1

The IASB’s Conceptual Framework states that
comparability is an enhancing qualitative
characteristic of financial information.
Related to comparability is consistency which refers
to the use of the same methods for the same items,
either from period to period within a reporting entity
or in a single period across entities.
When a change from one method to another will
improve its financial reporting, the entity can do so,
but the notes to the financial statements must report
the type of change, its justification, and its effect on
profit.

LOWER OF COST AND NET REALIZABLE VALUE
Inventory must be reported at NRV when
NRV is lower than cost.
NRV is the estimated
selling price in the
ordinary course of
business less the
estimated costs of
completion and the
estimated costs
necessary to make the
sale.
Can be applied two ways:
(1)
(2)
separately to each
individual item.
to major categories of
assets.
