Concepts Underlying Inventory Accounting (slide 1 of 2)
Inventory is considered a current asset because a company normally sells it within a year or within its operating cycle. For a merchandising company, inventory consists of goods owned and held for sale in the course of business. Manufacturing companies have three kinds of inventory: Raw materials (goods used in making products) Work in process (partially completed products) Finished goods ready for sale ©2014 Cengage Learning.

Concepts Underlying Inventory Accounting (slide 2 of 2)
The work in process and the finished goods have three cost components: Cost of the raw materials that go into the product Cost of the labor used to convert the raw materials to finished goods Overhead costs that support the production process. These include: Costs of indirect materials (such as packing materials) Indirect labor (such as the salaries of supervisors) Factory rent Depreciation of plant assets Utilities Insurance ©2014 Cengage Learning.

Accrual Accounting and Valuation of Inventories
The primary objective of inventory accounting is to apply accrual accounting to the determination of cost of inventory sold during the accounting period. Valuation of inventories is usually at cost. Inventory cost includes the following: Invoice price less purchases discounts Freight-in, including insurance in transit Applicable taxes and tariffs ©2014 Cengage Learning. All Rights Reserved.

Accrual Accounting and Valuation of Inventories
Inventory valuation depends on the prices of goods, which usually vary during the year. A company may have purchased identical lots of merchandise at different prices. For identical items, it is often impossible to tell which have been sold and which are still inventory. Thus, it is necessary to make an assumption about the order in which items have been sold. Because the assumed order of sale may or may not be the same as the actual order of sale, the assumption is really about the flow of costs rather than the flow of physical inventory. ©2014 Cengage Learning.

Goods Flows and Cost Flows
Goods flow refers to the actual physical measurement of goods in the operations of a company. Cost flow refers to the association of costs with their assumed flow. The assumed cost flow may or may not be the same as the actual goods flow. It is sometimes preferable to use an assumed cost flow that bears no relationship to goods flow because it results in a better estimate of income. ©2014 Cengage Learning. All Rights Reserved.

Merchandise in Transit (slide 1 of 2)
Because merchandise inventory includes all items that a company owns and holds for sale, the status of any merchandise in transit, whether the company is buying it or selling it, must be evaluated to see if the merchandise should be included in the inventory count. As shown on the next slide, ownership is determined by the terms of the shipping agreement, which indicate when title passes. ©2014 Cengage Learning. All Rights Reserved.

Merchandise in Transit (slide 2 of 2)
Outgoing goods shipped FOB destination are included in the seller’s merchandise inventory, whereas those shipped FOB shipping point are not. Incoming goods shipped FOB shipping point are included in the buyer’s merchandise inventory, but those shipped FOB destination are not. ©2014 Cengage Learning. All Rights Reserved. May not be scanned, copied or duplicated, or posted to a publicly accessible website, in whole or in part.

Merchandise Not Included in Inventory
At the time a company takes a physical inventory, it may have merchandise to which it does not hold title. Examples include: Goods sold but not yet delivered to the buyer Goods held on consignment—merchandise that its owner (the consignor) places on the premises of another company (the consignee) with the understanding that payment is expected only when the merchandise is sold and that unsold items may be returned to the consignor Goods to which the company does not hold title should not be included in its physical inventory. ©2014 Cengage Learning.

Conservatism and the Lower-of-Cost-or-Market (LCM) Rule
If the market value of inventory falls below its historical cost because of physical deterioration, obsolescence, or decline in the price level, a loss has occurred. This loss is recognized by writing the inventory down to market, or its current replacement cost. When the replacement cost of inventory falls below its historical cost, the lower-of-cost-or-market (LCM) rule requires that the inventory be written down to the lower value and that a loss be recorded. ©2014 Cengage Learning.

Disclosure of Inventory Methods
The disclosure concept requires that companies disclose their inventory methods, including the use of LCM, in the notes to their financial statements. ©2014 Cengage Learning. All Rights Reserved.

Summary of Inventory Decisions
In accounting for inventory, management must choose among different processing systems, costing methods, and valuation methods. These choices affect investors’ and creditors’ evaluations of a company, as well as the internal performance reviews on which bonuses and compensation are based. The consistency concept requires that once a company has decided on the accounting systems and methods it will use, it must use them from one period to the next. Federal income tax regulations are specific about the valuation methods a company may use, which can have a large impact on the income taxes a company pays. ©2014 Cengage Learning.

SECTION 2 ACCOUNTING APPLICATIONS
Calculate inventory cost under the periodic inventory system using the specific identification, average-cost, first-in, first-out (FIFO), and last-in, first-out (LIFO) methods. Calculate inventory cost under the perpetual inventory system using the specific identification, average-cost, first-in, first-out (FIFO), and last-in, first-out (LIFO) methods. Use the retail method to estimate the cost of ending inventory. Use the gross profit method to estimate the cost of ending inventory. ©2014 Cengage Learning. All Rights Reserved. May not be scanned, copied or duplicated, or posted to a publicly accessible website, in whole or in part.

Inventory Cost Under the Periodic Inventory System
The value assigned to the ending inventory is the result of two measurements: quantity and cost. Under the periodic inventory system, quantity is determined by taking a physical inventory. Cost is determined by using one of the following methods: specific identification, average-cost, first-in, first-out (FIFO), or last-in, first-out (LIFO). The choice of method depends on the nature of the business, the financial effects, and the cost of implementation. ©2014 Cengage Learning. All Rights Reserved.

Inventory Cost Under the Periodic Inventory System
To illustrate how each method is used under the periodic inventory system, we use Boilen Company, whose data for April is given below. ©2014 Cengage Learning. All Rights Reserved. May not be scanned, copied or duplicated, or posted to a publicly accessible website, in whole or in part.

Specific Identification Method
The specific identification method identifies the cost of each item in the ending inventory. It can be used only when it is possible to identify the units as coming from specific purchases. Although this method may appear logical, most companies do not use it for the following reasons: It is usually impractical, if not impossible, to keep track of the purchase and sale of individual items. When a company deals in items that are identical but bought at different prices, deciding which items were sold becomes arbitrary. ©2014 Cengage Learning. All Rights Reserved. May not be scanned, copied or duplicated, or posted to a publicly accessible website, in whole or in part.

If Boilen’s April 30 inventory consisted of 100 units from the April 1 inventory, 200 units from the April 6 purchase, and 140 units from the April 25 purchase, the specific identification method would assign the costs as follows. ©2014 Cengage Learning. All Rights Reserved. May not be scanned, copied or duplicated, or posted to a publicly accessible website, in whole or in part.

Average Cost Method Under the average-cost method (or weighted average method), inventory is priced at the average cost of the goods available for sale during the period. Average cost is computed as follows: Average Cost = Total Cost of Goods Available for Sale Total Units Available for Sale The average cost method tends to level out the effects of cost increases and decreases because the cost of the ending inventory is influenced by all the prices paid during the year and the cost of the beginning inventory. ©2014 Cengage Learning. All Rights Reserved. May not be scanned, copied or duplicated, or posted to a publicly accessible website, in whole or in part.

Average Cost Method For Boilen, the ending inventory under the average-cost method would be $5,588, or $12.70 per unit, determined as follows. ©2014 Cengage Learning. All Rights Reserved. May not be scanned, copied or duplicated, or posted to a publicly accessible website, in whole or in part.

First-In, First-Out (FIFO) Method
The first-in, first-out (FIFO) method assumes that the costs of the first items acquired should be assigned to the first items sold. The costs of the goods on hand at the end of a period are assumed to be from the most recent purchases, and the costs assigned to goods that have been sold are assumed to be from the earliest purchases. Thus, the FIFO method values the ending inventory at the most recent costs and includes earlier costs in the cost of goods sold. ©2014 Cengage Learning. All Rights Reserved. May not be scanned, copied or duplicated, or posted to a publicly accessible website, in whole or in part.

For Boilen, the FIFO method would result in an ending inventory of $6,100, computed as follows. ©2014 Cengage Learning. All Rights Reserved. May not be scanned, copied or duplicated, or posted to a publicly accessible website, in whole or in part.

Last-In, First-Out (LIFO) Method
The last-in, first-out (LIFO) method of costing inventories assumes that the costs of the last items purchased should be assigned to the first items sold and that the cost of the ending inventory should reflect the cost of the goods purchased earliest. The effect of LIFO is to value inventory at the earliest prices and to include the cost of the most recently purchased goods in the cost of goods sold. ©2014 Cengage Learning. All Rights Reserved. May not be scanned, copied or duplicated, or posted to a publicly accessible website, in whole or in part.

The supporters of LIFO reason that the fairest determination of income occurs if the current costs of merchandise are matched against current sales prices. When prices are moving up or down, the cost of goods sold will, under LIFO, show costs closer to the price level at the time the goods are sold. Thus, the LIFO method tends to show a smaller net income during inflationary times and a larger net income during deflationary times than other methods of inventory valuation, which tends to smooth out the peaks and valleys of the business cycle. However, because the inventory valuation on the balance sheet under LIFO reflects earlier prices, it often gives an unrealistic picture of the inventory’s current value. ©2014 Cengage Learning. All Rights Reserved. May not be scanned, copied or duplicated, or posted to a publicly accessible website, in whole or in part.

Under LIFO, Boilen’s April 30 inventory would be $5,100, computed as follows. ©2014 Cengage Learning. All Rights Reserved. May not be scanned, copied or duplicated, or posted to a publicly accessible website, in whole or in part.

Summary of Inventory Costing Methods

Effects of Inventory Costing Methods on Gross Margin
Assuming Boilen had April sales of $10,000, the graphic below shows how the specific identification, average-cost, FIFO, and LIFO methods of pricing inventory affect gross margin. ©2014 Cengage Learning. All Rights Reserved. May not be scanned, copied or duplicated, or posted to a publicly accessible website, in whole or in part.

Impact of Inventory Decisions
As the previous slide shows, in a period of rising prices, LIFO, which charges the most recent prices to the cost of goods sold, results in the lowest gross margin. In a period of rising prices, FIFO, which charges the earliest prices to the cost of goods sold, produces the highest gross margin. The gross margin under the average-cost method falls between the gross margins produced by LIFO and FIFO. ©2014 Cengage Learning. All Rights Reserved.

Inventory Costing Methods Used by 500 Large Companies

Effects on the Financial Statements
Among the factors managers should consider in choosing an inventory costing method are the trend of prices and the effects of each method on financial statements, income taxes, and cash flows. LIFO is best suited for the income statement because it matches revenues and the cost of goods sold. But it is not the best method for valuing inventory on the balance sheet, particularly during a prolonged period of price increases. FIFO is well suited to the balance sheet because the ending inventory is closer to current values. ©2014 Cengage Learning. All Rights Reserved.

Effects on Income Taxes (slide 1 of 2)
The Internal Revenue Service governs how inventories must be valued for federal income tax purposes. IRS regulations give companies a wide choice of inventory costing methods, including specific identification, average-cost, FIFO, and LIFO. Except when companies use the LIFO method, they may use the lower-of-cost-or-market rule. If a company wants to change the valuation method it uses for income tax purposes, it must have advance approval from the IRS. ©2014 Cengage Learning. All Rights Reserved. May not be scanned, copied or duplicated, or posted to a publicly accessible website, in whole or in part.

Effects on Income Taxes (slide 2 of 2)
Many accountants believe that using the FIFO and average-cost methods in periods of rising prices causes businesses to overstate their profits, resulting in excess income tax. During a period of rising prices, if a company that uses LIFO lets the inventory quantity at year end fall below the level at the beginning of the year, the company will pay higher income taxes. When sales have reduced inventories below the levels set in prior years, it is called a LIFO liquidation—that is, units sold exceed units purchased for the period. ©2014 Cengage Learning. All Rights Reserved. May not be scanned, copied or duplicated, or posted to a publicly accessible website, in whole or in part.

Effects on Cash Flows Generally speaking, a company’s choice of average cost, FIFO, or LIFO does not affect cash flows. However, the choice of inventory method will affect the amount of income tax paid. Choosing a method that results in lower income will result in lower taxes. ©2014 Cengage Learning.

Inventory Cost Under the Perpetual Inventory System
Under the perpetual inventory system, inventory is updated as purchases and sales take place. The cost of goods sold is accumulated as sales are made and costs are transferred from the Inventory account to the Cost of Goods Sold account. The cost of the ending inventory is the balance of the Inventory account. Goods are valued using one of these methods: specific identification, average-cost, FIFO, or LIFO. ©2014 Cengage Learning.

Inventory Cost Under the Perpetual Inventory System
To illustrate costing methods under the perpetual inventory system, Boilen Company’s data for April is used, as shown below. ©2014 Cengage Learning. All Rights Reserved. May not be scanned, copied or duplicated, or posted to a publicly accessible website, in whole or in part.

If Boilen’s April 30 inventory consisted of 100 units from the April 1 inventory, 200 units from the April 6 purchase, and 140 units from the April 25 purchase, the specific identification method would assign the costs as shown below. ©2014 Cengage Learning. All Rights Reserved. May not be scanned, copied or duplicated, or posted to a publicly accessible website, in whole or in part.

Average-Cost Method Under the perpetual system, an average is computed after each purchase or series of purchases, as shown below. ©2014 Cengage Learning. All Rights Reserved. May not be scanned, copied or duplicated, or posted to a publicly accessible website, in whole or in part.

FIFO Method When costing inventory with the FIFO or LIFO methods, it is necessary to keep track of the components of inventory because, as sales are made, the costs must be assigned in the proper order. The FIFO method is applied as shown below. ©2014 Cengage Learning. All Rights Reserved. May not be scanned, copied or duplicated, or posted to a publicly accessible website, in whole or in part.

LIFO Method The LIFO method is applied as shown below. The ending inventory of $6,000 includes 40 units from the beginning inventory and 400 units from the April 25 purchase. ©2014 Cengage Learning. All Rights Reserved. May not be scanned, copied or duplicated, or posted to a publicly accessible website, in whole or in part.

Summary of Inventory Costing Methods
The graphic below compares the specific identification, average-cost, FIFO, and LIFO methods under the perpetual inventory system for Boilen. ©2014 Cengage Learning. All Rights Reserved. May not be scanned, copied or duplicated, or posted to a publicly accessible website, in whole or in part.

Valuing Inventory by Estimation
It is sometimes necessary or desirable to estimate the value of the ending inventory. The most commonly used methods for this purpose are: the retail method, which estimates the cost of the ending inventory by using the ratio of cost to retail price. the gross profit method (or gross margin method), which assumes that the ratio of gross margin for a business remains relatively stable from year to year. ©2014 Cengage Learning. All Rights Reserved. May not be scanned, copied or duplicated, or posted to a publicly accessible website, in whole or in part.

Retail Method (slide 1 of 2)
Retail merchandising businesses use the retail method for two main reasons: To prepare financial statements for each period, the retail method can be used to estimate the cost without taking time or going to the expense of determining the cost of each item in the inventory. Because items in a retail store normally have a price tag or universal product code, it is common practice to take the physical inventory “at retail” from these price tags or codes and to reduce the total value to cost by using the retail method. ©2014 Cengage Learning. All Rights Reserved. May not be scanned, copied or duplicated, or posted to a publicly accessible website, in whole or in part.

Retail Method (slide 1 of 2)
Goods available for sale is determined at cost and at retail by listing the beginning inventory and net purchases for the period at cost and at their expected selling price, adding freight-in to the Cost column, and totaling. The ratio of these two amounts (cost to retail price) provides an estimate of the cost of each dollar of retail sales value. The estimated ending inventory at retail is then determined by deducting sales from the retail price of the goods that were available for sale. The inventory at retail is then converted to cost on the basis of the ratio of cost to retail, as shown on the next slide. ©2014 Cengage Learning. All Rights Reserved. May not be scanned, copied or duplicated, or posted to a publicly accessible website, in whole or in part.

Retail Method of Inventory Estimation

Gross Profit Method The gross profit method is used in place of the retail method when records of the retail prices of the beginning inventory and purchases are not available. This method is acceptable for estimating the cost of inventory for insurance claims and for interim reports, but it is not acceptable for valuing inventory in the annual financial statements. ©2014 Cengage Learning. All Rights Reserved. May not be scanned, copied or duplicated, or posted to a publicly accessible website, in whole or in part.

Gross Profit Method As shown on the next slide, the gross profit method involves the following steps: 1. Calculate the cost of goods available for sale in the usual way (add purchases to beginning inventory) 2. Estimate the cost of goods sold by deducting the estimated gross margin of 30 percent from sales. 3. Deduct the estimated cost of goods sold from the goods available for sale to arrive at the estimated cost of the ending inventory. ©2014 Cengage Learning. All Rights Reserved.

Gross Profit Method of Inventory Estimation

Inventory and the Financial Statements
Cost of goods sold is created by transferring from the balance sheet to the income statement the cost of the inventories sold during the period. The amount of the transfer depends on the valuation of inventories. ©2014 Cengage Learning. All Rights Reserved.

SECTION 3 BUSINESS APPLICATIONS
Evaluate the level of inventory Inventory turnover Days’ inventory on hand Manage the level of inventory Supply-chain management Just-in-time operating environment Evaluate the effects of inventory misstatements on income measurement ©2014 Cengage Learning. All Rights Reserved. May not be scanned, copied or duplicated, or posted to a publicly accessible website, in whole or in part.

Evaluating the Level of Inventory
The level of inventory a company maintains has important economic consequences, and it involves conflicting goals. One goal is to have a great variety and quantity of goods on hand so that customers have a choice and do not have to wait for an item to be restocked. This conflicts with the goal of controlling costs, which favors keeping the level of inventory low. Managers control inventory by closely observing two ratios: inventory turnover and days’ inventory on hand. ©2014 Cengage Learning. All Rights Reserved. May not be scanned, copied or duplicated, or posted to a publicly accessible website, in whole or in part.

Inventory Turnover Inventory turnover is the average number of times a company sells an amount equal to its average level of inventory during a period. ©2014 Cengage Learning. All Rights Reserved. May not be scanned, copied or duplicated, or posted to a publicly accessible website, in whole or in part.

Days’ Inventory on Hand
Day’s inventory on hand is the average number of days it takes a company to sell an amount equal to its average inventory. ©2014 Cengage Learning. All Rights Reserved. May not be scanned, copied or duplicated, or posted to a publicly accessible website, in whole or in part.

Inventory Management To reduce their levels of inventory, many merchandisers and manufacturers use supply-chain management in conjunction with a just-in-time operating environment. With supply-chain management, a company uses the Internet to order and track goods that it needs immediately. A just-in-time (JIT) operating environment is one in which goods arrive just at the time they are needed. ©2014 Cengage Learning. All Rights Reserved. May not be scanned, copied or duplicated, or posted to a publicly accessible website, in whole or in part.

Effects of Inventory Misstatements on Income Measurement
The reason inventory accounting is so important to income measurement is the way income is measured. The higher the value of the ending inventory, the lower the cost of goods sold and the higher the gross margin. The lower the value of the ending inventory, the higher the cost of goods sold and the lower the gross margin. Because the figures for the ending inventory and the cost of goods sold are related, a misstatement in the inventory figure will cause an equal misstatement in gross margin and income before income taxes. ©2014 Cengage Learning. All Rights Reserved. May not be scanned, copied or duplicated, or posted to a publicly accessible website, in whole or in part.

Inventory Misstatements and Fraud
Inventory is particularly susceptible to fraudulent financial reporting. It is easy to overstate or understate inventory by including end-of-the-year purchase and sale transactions in the wrong fiscal year or by simply misstating inventory by mistake. A misstatement can also occur because of deliberate manipulation of operating results motivated by a desire to enhance the market’s perception of the company, obtain bank financing, or achieve compensation incentives. ©2014 Cengage Learning.

Inventory Misstatements Illustrated (slide 2 of 2)
Because the ending inventory in one period becomes the beginning inventory in the following period, a misstatement in inventory valuation affects both periods. Over two periods, the errors in income before income taxes will offset, or counterbalance, each other. ©2014 Cengage Learning. All Rights Reserved.
