INVENTORY COSTING
INVENTORY BASICS



In the balance sheet of merchandising and
manufacturing companies, inventory is
frequently the most significant current asset.
In the income statement, inventory is vital in
determining the results of operations for a
particular period.
Gross profit (net sales - cost of goods sold)
is closely watched by management,
owners, and other interested parties.
Perpetual vs. Periodic
Inventory Accounting


Perpetual
– Updates inventory and cost of goods sold
after every purchase and sales transaction
Periodic
– Delays updating of inventory and cost of
goods sold until end of the period
– Misstates inventory during the period
This chapter covers the periodic inventory method.
DETERMINING INVENTORY
QUANTITIES
In order to prepare financial statements, it is necessary
to determine the number of units of inventory owned by
the company at the statement date, and to value them.
 The determination of inventory quantities involves
1. taking a physical inventory of goods on hand, and
2. determining the ownership of goods.
 Taking a physical inventory involves counting,
weighing, or measuring each kind of inventory on hand.

TAKING A PHYSICAL INVENTORY
A company, in order to minimize errors in
taking the inventory, should adhere to
internal control principles by adopting the
following procedures:
1. Employees who do not have custodial
responsibility for the inventory should do
the counting (segregation of duties).
2. Each counter should establish the
authenticity of each inventory item
(establishment of responsibility).
TAKING A PHYSICAL INVENTORY
3. Another employee should make a second
count (independent verification).
4. All inventory tags should be pre-numbered
and accounted for (documentation
procedures).
5. At the end of the count, a designated
supervisor should ascertain that all
inventory items are tagged and that no
items have more than one tag
(independent verification).

DETERMINING OWNERSHIP OF
CONSIGNED GOODS



Under a consignment arrangement, the
holder of the goods (called the consignee)
does not own the goods.
Ownership remains with the shipper of the
goods (consignor) until the goods are
actually sold to a customer.
Consigned goods should be included in the
consignor’s inventory, not the consignee’s
inventory.

USING ACTUAL PHYSICAL
FLOW COSTING



The specific identification method tracks the
actual physical flow of the goods.
Each item of inventory is marked, tagged, or
coded with its specific unit cost.
It is most frequently used when the company
sells a limited variety of high unit-cost items.
USING ASSUMED COST
FLOW METHODS



Other cost flow methods are allowed since
specific identification is often impractical.
These methods assume flows of costs that
may be unrelated to the physical flow of
goods.
Cost flow assumptions:
1. First-in, first-out (FIFO).
2. Average cost.
3. Last-in, first-out (LIFO).
FIFO



The FIFO method assumes that the earliest
goods purchased are the first to be sold.
Often reflects the actual physical flow of
merchandise.
Under FIFO, the costs of the earliest goods
purchased are the first to be recognized as
cost of goods sold. The costs of the most
recent goods purchased are recognized as
the ending inventory.
FIFO method assumes earliest
goods purchased are the first to
be sold
AVERAGE COST



The average cost method assumes that the
goods available for sale are homogeneous.
The allocation of the cost of goods
available for sale is made on the basis of
the weighted average unit cost incurred.
The weighted average unit cost is then
applied to the units sold to determine the
cost of goods sold and to the units on hand
to determine the ending inventory.
Allocation of the cost of goods
available for sale in average cost
method is made on the basis of
the weighted average unit cost
Average cost method assumes that
goods available for sale are
homogeneous
LIFO




The LIFO method assumes that the latest
goods purchased are the first to be sold
and that the earliest goods purchased
remain in ending inventory.
Seldom coincides with the actual physical
flow of inventory.
Under the periodic method, all goods
purchased during the year are assumed to
be available for the first sale, regardless of
date of purchase.
Rarely used in Canada.
LIFO method assumes latest goods
purchased are the first to be sold
INCOME STATEMENT EFFECTS



In periods of rising prices, FIFO reports the
highest net income, LIFO the lowest and
average cost falls in the middle.
The reverse is true when prices are
falling.
When prices are constant, all cost flow
methods will yield the same results.
BALANCE SHEET EFFECTS
FIFO produces the best balance sheet
valuation since the inventory costs are closer
to their current, or replacement, costs.
USING INVENTORY COST FLOW
METHODS CONSISTENTLY



A company needs to use its chosen cost
flow method consistently from one
accounting period to another.
Such consistent application enhances the
comparability of financial statements over
successive time periods.
When a company adopts a different cost
flow method, the change and its effects on
net income should be disclosed in the
financial statements.
INVENTORY ERRORS - INCOME
STATEMENT EFFECTS



Both beginning and ending inventories appear
on the income statement.
The ending inventory of one period
automatically becomes the beginning
inventory of the next period.
Inventory errors affect the
determination of cost of goods
sold and net income.

An error in ending inventory of the current period
will have a reverse effect on net income of the next

ENDING INVENTORY ERROR –
BALANCE SHEET EFFECTS
The effect of ending inventory errors on the
balance sheet can be determined by using the
basic accounting equation:

VALUING INVENTORY AT THE
LOWER OF COST AND MARKET



When the value of inventory is lower than
the cost, the inventory is written down to
its market value.
This is known as the lower of cost and
market (LCM) method.
Market is defined as replacement cost or
net realizable value.
