Inventory Costing
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.
Inventory Basics
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
Mis-states inventory during the period
This chapter covers the periodic inventory method.
Perpetual vs Periodic Costing
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.
Determining Inventory Quantities
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 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).

HIGHPOINT ELECTRONICSIncome Statement
The multi-step income statement under the periodic system requires more detail in the cost
of goods sold section, as shown above.
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. A deluxe sports car dealership for instance
Using Actual Physical Flow
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).
Using Assumed Cost Flow Methods
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.
First In, First Out
FIFO method assumes earliest goods purchased are the first to be sold
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.
Average Cost Method
Average cost method assumes that goods available for sale are homogeneous
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.
Last In, First Out
LIFO method assumes latest goods purchased are the first to be sold
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.
Important Income Statement Effects
FIFO produces the best balance sheet valuation since the inventory costs are closer to their current, or replacement, costs.
Balance Sheet Effects
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.
Using Inventory Valuation Methods Consistently
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.
Inventory Errors – Effects on the Income Statement
Cost of Inventory Error Goods Sold Net Income
An error in ending inventory of the current periodwill have a reverse effect on net income of the next
accounting period.
Understate beginning inventory Understated Overstated
Overstate beginning inventory Overstated Understated
Understate ending inventory Overstated Understated
Overstate ending inventory Understated Overstated
Effects of Inventory Errors on Current Year’s Income Statement
The effect of ending inventory errors on the balance sheet can be determined by using the basic accounting equation:
Assets = Liabilities + Owner’s Equity Ending Inventory
Error Assets Liabilities Owner’s Equity
Overstated Overstated None Overstated Understated Understated None Understated
Effects of Inventory Errors on Current Year’s Balance Sheet
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.

The common practice is to use total inventory rather than individual items or major
categories in determining the LCM valuation.
