4. Copyright John Wiley & Sons Canada, Ltd.4 All companies count their inventory at least once a year – Must determine amount and value of inventory to prepare accurate financial statements The determination of inventory quantities involves – Taking a physical inventory of goods on hand – Determining the ownership of the goods Determining Inventory Quantities

5. Copyright John Wiley & Sons Canada, Ltd.5 Involves counting, weighing, or measuring each kind of inventory on hand Strong internal controls needed for an accurate inventory count: – Count done by employees not normally responsible for inventory – Confirm items counted exist by observation – Second count by another employee – Ensure all items are counted only once and nothing is missed (use pre-numbered tags) The quantity of each type of good is then multiplied by its unit cost to determine the total cost of the inventory Taking a Physical Inventory

6. Copyright John Wiley & Sons Canada, Ltd.6 Only include inventory owned by company Goods in Transit: – On board a public carrier as at the count date – Look at FOB point to determine if they should be included Consigned Goods: – Goods being sold that are owned by others – Excluded from inventory of consignee (who is selling on behalf of the owner, the consignor) Determining Ownership

Chapter 6: Inventory Costing Study Objectives

8. Inventory Cost Determination Copyright John Wiley & Sons Canada, Ltd.8 Specific Identification – Tracks the actual physical flow of goods – Each inventory item is marked with its cost – Used where goods are not ordinarily interchangeable Cost Formulas – Specific identification not always suitable – A cost formula is used instead: First-in, first-out (FIFO) Average – Flow of costs may not match physical flow

9. Copyright John Wiley & Sons Canada, Ltd.9 Inventory Costing in a Perpetual Inventory System FIFO: – FIFO rule is applied at the time of each sale – FIFO (First-in, first-out) Average: – New average cost per unit is calculated after each purchase

10. Copyright John Wiley & Sons Canada, Ltd.10 Perpetual Inventory System: First-in, First-out (FIFO) FIFO assumes earliest goods are sold first Costing: – Costs of oldest goods purchased are first to be recognized as Cost of Goods Sold – Costs of most recent goods purchased are recognized as the ending inventory Often reflects the actual physical flow of merchandise

11. Ending inventory and cost of goods sold under FIFO is the same for perpetual and periodic systems Copyright John Wiley & Sons Canada, Ltd.11 Perpetual System Inventory Costing: FIFO

12. Copyright John Wiley & Sons Canada, Ltd.12 Assumes that it is not practical to measure specific physical flow of inventory – Therefore better to use an average price Uses a weighted average unit cost Applied when goods are sold: – to units sold to determine cost of goods sold – to units on hand to determine ending inventory Perpetual Inventory System: Average

13. Copyright John Wiley & Sons Canada, Ltd.13 Under a perpetual inventory system, a new weighted average is calculated after each purchase. This average is then applied to: – Units sold, to determine cost of goods sold – Remaining units on hand, to determine ending inventory Perpetual System Inventory Costing: Average (Continued)

Chapter 6: Inventory Costing Study Objectives

15. Financial Statement Effects Copyright John Wiley & Sons Canada, Ltd.15 Income statement effect: – When prices rising, FIFO produces higher profit – When prices falling, opposite is true Balance sheet effect: – FIFO provides the most current valuation of inventory – More closely approximates replacement cost Cost formula should be used consistently – Enhances comparability of statements over time – Choose the method that best corresponds with actual physical flow

Chapter 6: Inventory Costing Study Objectives

17. Inventory Errors Copyright John Wiley & Sons Canada, Ltd.17 Errors in inventory affect both income statement and balance sheet – Through the calculation of cost of goods sold Ending inventory of one period becomes beginning inventory of the next period – Errors in ending inventory carry over to the following period

18. Income Statement Effects Copyright John Wiley & Sons Canada, Ltd.18 Effect of inventory errors on the current year’s income statement: An error in ending inventory of one period will have the reverse effect on profit of the next period

19. Balance Sheet Errors Copyright John Wiley & Sons Canada, Ltd.19 Effect can be determined by using the basic accounting equation: Assets = Liabilities + Owner’s Equity An error in ending inventory in one period will cause an error in beginning inventory in the next period

Chapter 6: Inventory Costing Study Objectives

21. Inventory Valuation Copyright John Wiley & Sons Canada, Ltd.21 Lower of cost and net realizable value – when the value of inventory is lower than cost, it is written down to that lower value – Net realizable value: selling price less any costs to make the goods ready for sale Assessed on an item-by-item basis Reversed if net realizable value increases before goods are sold

23. Classifying & Reporting Inventory Copyright John Wiley & Sons Canada, Ltd.23 Depends on whether company is a merchandiser or manufacturer – Merchandiser buys its inventory – only one classification used – Manufacturer produces its inventory – classified into raw materials, work in process and finished goods Typically recorded as a current asset, but can be non-current if not sold in one year

24. Analysis of Inventory Copyright John Wiley & Sons Canada, Ltd.24 Must balance competing objectives: – Excessive levels of inventory leads to high carrying costs – Too little inventory may result in lost sales Ratios help determine whether a company has too much or too little inventory: – Inventory turnover ratio – Days sales in inventory

25. Inventory Turnover Ratio Copyright John Wiley & Sons Canada, Ltd.25 = Cost of Goods Sold ÷ Average Inventory The number of times inventory “turns over” during a given period The more times inventory turns over, the more efficiently sales are being made Average inventory is usually average of beginning and ending inventories

26. Day Sales in Inventory Copyright John Wiley & Sons Canada, Ltd.26 = Days in Year ÷ Inventory Turnover The number of days on average that the inventory is on hand before being sold Compare over years and with industry averages

Chapter 6: Inventory Costing Study Objectives

31. Copyright John Wiley & Sons Canada, Ltd.31 Not always possible or practical to count inventory – must be estimated – Two estimating methods are available Gross profit method – Estimated gross profit = net sales × gross profit margin – Estimated cost of goods sold = net sales − estimated gross profit – Estimated ending inventory = goods available for sale − cost estimated cost of goods sold Appendix 6B: Estimating Inventories

32. Copyright John Wiley & Sons Canada, Ltd.32 Retail inventory method uses the cost-to- retail ratio applied to ending inventory at retail to determine the estimated cost of the inventory Calculation: 1.Ending inventory at retail = goods available for sale at retail − net sales 2.Cost-to-retail ratio = goods available for sale at cost ÷ goods available for sale at retail 3.Estimated cost of ending inventory = ending inventory at retail × cost-to-retail ratio Appendix 6B: Estimating Inventories 2
