Inventory Subsidiary Ledger Accounts
Companies that use the perpetual system maintain an inventory control account and an
inventory subsidiary ledger with separate accounts for each type of item the business
sells. Whenever a transaction affects inventory, the specific item's subsidiary ledger
account is also updated. Inventory subsidiary ledger accounts usually contain separate
sets of columns for purchases, sales, and the account balance. Each set has three
columns, which are used to record the number of units, the cost of each unit, and the
total cost. The inventorytires account from the previous example appears below.
The numbers in the maximum and minimum fields near the upper left corner of the
account are optional control fields designed to prevent the company from having too
many or too few of the items in stock. In this example, the company purchases new tires
whenever the overall number of units in stock drops to seven or less, and the number
purchased should never cause the company's stock to exceed fifteen units.
If you study the journal entries on the subsidiary ledger account immediately previous,
you will notice that the cost of the tires sold on April 22 changes from $100 in the journal
entries to $99 in the inventory account. These examples illustrate two different cost flow
methods, so they are intended to be used for illustration purposes only. A company
must use one cost flow method consistently.
Cost Flow Methods
The cost of items remaining in inventory and the cost of goods sold are easy to
determine if purchase prices and other inventory costs never change, but price

fluctuations may force a company to make certain assumptions about which items have
sold and which items remain in inventory. There are four generally accepted methods
for assigning costs to ending inventory and cost of goods sold: specific cost; average
cost; firstin, firstout (FIFO); and lastin, firstout (LIFO). Each method is applied to the
information in the following illustrations, summarizing the activity in one inventory
subsidiary ledger account at a company named Zapp Electronics.

The cost of goods available for sale equals the beginning value of inventory plus the
cost of goods purchased. Two purchases occurred during the year, so the cost of goods
available for sale is $ 7,200.

Specific cost. Companies can use the specific cost method only when the purchase
date and cost of each unit in inventory is identifiable. For the most part, companies that
use this method sell a small number of expensive items, such as automobiles or
appliances.
If specially coded price tags or some other technique enables Zapp Electronics to
determine that 15 units in ending inventory were purchased on April 10 and the
remaining 85 units were purchased on October 10, then the ending value of inventory
and the cost of goods sold can be determined precisely.

Since the specific cost of each unit is known, the resulting values for ending inventory
and cost of goods sold are not affected by whether the company uses a periodic or
perpetual system to account for inventory. The only difference between the systems is
that the value of inventory and the cost of goods sold is determined every time a sale
occurs under the perpetual system, and these amounts are calculated at the end of the
accounting period under the periodic system. Check the value found for cost of goods
sold by multiplying the 350 units that sold by their per unit cost.
