Inventories (continued) Describe the cost of inventory under the 4 After studying this chapter, you should be able to: periodic inventory system, using the FIFO, LIFO, and average cost methods. 7 -3 5 Compare and contrast the use of the three inventory costing methods. 6 Describe and illustrate the reporting of merchandise inventory in the financial statements.

1 Describe the importance of control over inventory. 7 -4

1 Two primary objectives of control over inventory are: 1. Safeguarding the inventory, and 2. Properly reporting it in the financial statements. 7 -

1 • The purchase order authorizes the purchase of the inventory from an approved vendor. • The receiving report establishes an initial record of the receipt of the inventory. • The amount of inventory is always available in the subsidiary inventory ledger. 7 -

1 Controls for safeguarding inventory should include security measures to prevent damage and customer or employee theft. Some examples of security measures include the following: 1. Storing inventory in areas that are restricted to only authorized employees. 7 -

1 2. Locking high-priced inventory in cabinets. 3. Using two-way mirrors, cameras, security tags, and guards. 7 -

1 A physical inventory or count of inventory should be taken near year-end to make sure that the quantity of inventory reported in the financial statements is accurate. 7 -

2 Describe three inventory cost flow assumptions and how they impact the income statement and balance sheet. 7 -7 -10

2 May 10 Purchase 18 Purchase 24 Purchase Total 1 1 1 3 $ 9 13 14 $36 Average cost per unit $12 ($36 ÷ 3 units) 7 -

2 Assume that one unit is sold on May 30 for $20. Depending upon which unit was sold, the gross profit varies from $11 to $6 as shown below: 7 -

2 Under the specific identification inventory cost flow method, the unit sold is identified with a specific purchase. Not practical unless each inventory unit can be separately identified. 7 -

2 Under the first-in, first out (FIFO) inventory cost flow method, the first units purchased are assumed to be sold and the ending inventory is made up of the most recent purchases. 7 -

2 Under the last-in, first out (LIFO) inventory cost flow method, the last units purchased are assumed to be sold first and the ending inventory is made up of the first units purchased. 7 -

2 Under the average inventory cost flow method, the cost of the units sold and in ending inventory is an average of the purchase costs. 7 -

3 Example Exercise 7 -2 Perpetual Inventory Using FIFO Beginning inventory, purchases, and sales for Item ER 27 are as follows: Nov. 1 Inventory 40 units at $5 5 Sale 32 units 11 Purchase 60 units at $7 21 Sale 45 units Assuming a perpetual inventory system and the first-in, first-out (FIFO) method, determine (a) the cost of the merchandise sold for the November 21 sale and (b) the inventory on November 30. 7 -37 7 -

3 Example Exercise 7 -2 (continued) Follow My Example 7 -2 a) Cost of merchandise sold (November 21): 8 units @ $5 $40 37 units @ $7 259 45 units $299 b) Inventory, November 30: $161 = (23 units × $7) For Practice: PE 7 -2 A, PE 7 -2 B 7 -38 7 -

3 Last-In, First-Out Method On January 1, the firm had 100 units of Item 127 B that cost $20 per unit. Item 127 B Units Cost 100 7 - Jan. $20 1 Inventory

3 Last-In, First-Out Method On January 4, the firm sold 70 units of 127 B at $30 each. Item 127 B Units 7 - Cost Jan. 1 100 4 $20 Sale 70 Inventory

3 Exhibit 4 Entries and Perpetual Inventory Account (LIFO) (concluded) Cost of Merchandise Sold 7 - January 31 Inventory

3 Example Exercise 7 -3 Perpetual Inventory Using LIFO Beginning inventory, purchases, and sales for Item ER 27 are as follows: Nov. 1 5 11 21 Inventory Sale Purchase Sale 40 units at $5 32 units 60 units at $7 45 units Assuming a perpetual inventory system and the last-in, first-out (LIFO) method, determine (a) the cost of the merchandise sold for the November 21 sale and (b) the inventory on November 30. 7 -51 7 -

3 Example Exercise 7 -3 (continued) Follow My Example 7 -3 a) Cost of merchandise sold: $315 = (45 units × $7) b) Inventory, November 30: c) d) e) 8 units @ $5 15 units @ $7 23 $ 40 105 $145 For Practice: PE 7 -3 A, PE 7 -3 B 7 -52

3 Moving Average When the average cost is used in a perpetual system, an average unit cost for each item is computed each time a purchase is made. The unit cost is then used to determine the cost of each sale until another purchase is made and a new average is computed. This averaging technique is called a moving average. 7 -

4 Determine the cost of inventory under the periodic inventory system, using the FIFO, LIFO, and average cost methods. 7 -54 7 -

4 First-In, First-Out Method Using FIFO, the earliest batch purchased is considered the first batch of merchandise sold. The physical flow does not have to match the accounting method chosen. 7 -

4 FIFO Method Jan. 1 100 units @ $20 = $2, 000 Jan. 10 80 units @ $21 = 1, 680 Jan. 30 100 units @ $22 = 2, 200 280 units available for sale during year $5, 880 Cost of merchandise available for sale 7 -

4 The physical count on January 31 shows that 150 units are on hand (conclusion: 130 units were sold). What is the cost of the ending inventory? Jan. 1 100 Sold unitsthese @ $20 Sold 30 of the 80 $ 0 Jan. 10 80 units @ $21 50 units @ $21 = 1, 050 Jan. 30 100 units @ $22 = 2, 200 Ending inventory 7 - = $3, 250

4 Now we can calculate the cost of goods sold as follows: Beginning inventory, January 1 (Slide 55) Purchases ($1, 680 + $2, 200) Cost of merchandise available for sale Ending inventory, January 31(Slide 56) Cost of merchandise sold 7 - $2, 000 3, 880 $5, 880 3, 250 $2, 630

4 Exhibit 5 7 - First-In, First-Out Flow of Costs

4 Last-In, First-Out Method Using LIFO, the most recent batch purchased is considered the first batch of merchandise sold. The actual flow of goods does not have to be LIFO. For example, a store selling fresh fish would want to sell the oldest fish first (which is FIFO) even though LIFO is used for accounting purposes. 7 -

4 LIFO Method Jan. 1 100 units @ $20 = $2, 000 Jan. 10 80 units @ $21 = 1, 680 Jan. 30 100 units @ $22 = 2, 200 280 units available for sale during year $5, 880 Cost of merchandise available for sale 7 -

4 Assume again that the physical count on January 31 is 150 units (and that 130 units were sold). What is the cost of the ending inventory? Jan. 1 100 units @ $20 = $2, 000 Jan. 10 50 units @ $21 80 units @ $21 == 1, 1, 050 680 100 Sold unitsthese @ $22 == 2, 2000 Sold 30 of the 80 Jan. 30 Ending inventory 7 - $3, 050

4 Now we can calculate the cost of goods sold as follows: Beginning inventory, January 1 (Slide 60) Purchases ($1, 680 + $2, 200) Cost of merchandise available for sale Ending inventory, January 31(Slide 61) Cost of merchandise sold 7 - $2, 000 3, 880 $5, 880 3, 050 $2, 830

4 Exhibit 5 7 - Last-In, First-Out Flow of Costs

4 Average Cost Method The average cost method is sometimes called the weighted average method. It uses the average unit cost for determining cost of merchandise sold and the ending merchandise inventory. 7 -

4 The weighted average unit cost is determined as follows: Total Cost of Units Available for Sale Average Unit Cost = Units Available for Sale 7 -

4 Jan. 1 100 units @ $20 = $2, 000 Jan. 10 80 units @ $21 = 1, 680 Jan. 30 100 units @ $22 = 2, 200 280 $5, 880 Average unit cost: $5, 880 ÷ 280 = $21 Cost of merchandise sold: 130 units at $21 = $2, 730 Ending merchandise inventory: 150 units at $21= $3, 150 7 -

4 Now we can calculate the cost of goods sold as follows: Beginning inventory, January 1 (Slide 66) $2, 000 Purchases ($1, 680 + $2, 200) 3, 880 Cost of merchandise available for sale $5, 880 Ending inventory, January 31(Slide 66) 3, 150 Cost of merchandise sold $2, 730 7 -

4 Example Exercise 7 -4 Periodic Inventory Using FIFO, LIFO, Average Cost Methods The units of an item available for sale during the year were as follows: Jan. 1 Inventory Mar. 20 Purchase Oct. 30 Purchase Available for sale 6 units @ $50 14 units @ $55 20 units @ $62 40 units $ 300 770 1, 240 $2, 310 There are 16 units of the item in the physical inventory at December 31. The periodic inventory system is used. Determine the inventory cost by (a) the first-in, first-out (FIFO) method, (b) the last-in, first-out (LIFO) method, and (c) the average cost method. 7 -69 7 -

4 Example Exercise 7 -4 (continued) Follow My Example 7 -4 a) First-in, first-out (FIFO) method: $992 (16 units × $62) b) Last-in, first-out (LIFO) method: $850 (6 units × $50) + (10 units × $55) c) Average method: $924 (16 units × $57. 75) where average cost = $57. 75 ($2, 310 ÷ 40 units) For Practice: PE 7 -4 A, PE 7 -4 B 7 -70 7 -

6 Describe and illustrate the reporting of merchandise inventory in the financial statements. 7 -77 7 -

6 Cost is the primary basis for valuing and reporting inventories in the financial statements. However, inventory may be valued at other than cost in the following cases: (continued) 7 -

6 1. The cost of replacing items in inventory is below the recorded cost. 2. The inventory cannot be sold at normal prices due to imperfections, style changes, or other causes. 7 -

6 Market, as used in lower of cost or market, is the cost to replace the merchandise on the inventory date. 7 -

6 Cost and replacement cost can be determined for the following: 1. Each item in the inventory. 2. Each major class or category of inventory. 3. Total inventory as a whole. 7 -

6 Exhibit 8 7 - Determining Inventory at Lower of Cost or Market

6 Example Exercise 7 -5 Lower-of-Cost-or-Market Method On the basis of the following data, determine the value of the inventory at the lower of cost or market. Apply lower of cost or market to each inventory item as shown in Exhibit 8. Inventory Commodity Quantity C 17 Y B 563 7 -83 7 - 10 7 Unit Cost Price $ 39 110 Unit Market Price $40 98

6 Example Exercise 7 -5 (continued) Follow My Example 7 -5 For Practice: PE 7 -5 A, PE 7 -5 B 7 -84 7 -

6 Net Realizable Value Merchandise that is out of date, spoiled, or damaged should be written down to its net realizable value. This is the estimated selling price less any direct cost of disposal, such as sales commissions. 7 -

6 Merchandise Inventory on the Balance Sheet Merchandise inventory is usually presented in the Current Assets section of the balance sheet, following receivables. 7 -

6 Merchandise Inventory on the Balance Sheet The method of determining the cost of inventory (FIFO, LIFO, or weighted average) and the method of valuing the inventory (cost or the lower of cost or market) should be shown. 7 -

6 7 -

6 Effect of Inventory Errors on the Financial Statements Some reasons causing inventory errors to occur include the following: 1. Physical inventory on hand was miscounted. 2. Costs were incorrectly assigned to inventory. 3. Inventory in transit was incorrectly included or excluded from inventory. 4. Consigned inventory was incorrectly included or excluded from inventory. 7 -
