3. 8-3 In a perpetual inventory system, inventory entries parallel the flow of costs. The Flow of Inventory Costs

4. 8-4 When identical units of inventory have different unit costs, a question naturally arises as to which of these costs should be used in recording a sale of inventory. Which Unit Did We Sell?

5. 8-5 Inventory Subsidiary Ledger A separate subsidiary account is maintained for each item in inventory. How can we determine the unit cost for the Sept. 10 sale?

6. 8-6 The Bike Company (TBC) Data for an Illustration

7. 8-7 On August 14, TBC sold 20 bikes for $130 each. Of the bikes sold 9 originally cost $91 and 11 cost $106. On August 14, TBC sold 20 bikes for $130 each. Of the bikes sold 9 originally cost $91 and 11 cost $106. Specific Identification Specific Identification The Cost of Goods Sold for the August 14 sale is $1,985.

21. 8-21 Once a company has adopted a particular accounting method, it should follow that method consistently rather than switch methods from one year to the next. The Principle of Consistency

22. 8-22 The primary reason for taking a physical inventory is to adjust the perpetual inventory records for unrecorded shrinkage losses, such as theft, spoilage, or breakage. Taking a Physical Inventory

23. 8-23 Reduces the value of the inventory. Obsolescence Adjust inventory value to the lower of historical cost or current replacement cost (market). Lower of Cost or Market (LCM) LCM and Other Write-Downs of Inventory

37. 8-37 An error in ending inventory in a year will result in the same error in the beginning inventory of the next year. Importance of an Accurate Valuation of Inventory

38. 8-38 The Gross Profit Method 1.Determine cost of goods available for sale. 2.Estimate cost of goods sold by multiplying the net sales by the cost ratio. 3.Deduct cost of goods sold from cost of goods available for sale to determine ending inventory. 1.Determine cost of goods available for sale. 2.Estimate cost of goods sold by multiplying the net sales by the cost ratio. 3.Deduct cost of goods sold from cost of goods available for sale to determine ending inventory.

39. 8-39 The Gross Profit Method In March of 2009, Matrix Company’s inventory was destroyed by fire. Matrix normal gross profit ratio is 30% of net sales. At the time of the fire, Matrix showed the following balances:
