The Special Significance of Audit of Inventories The valuation of goods on hand and in process often presents complex and difficult issues Determining the quantities of inventories may require specialized techniques Inventories often represent the largest current asset of a company Misstatements of inventories directly affect cost of goods sold and, therefore, net income Management fraud has often involved the fraudulent overstatement of inventories 12-2 4 2

Objectives 1. Use the understanding of the client and its environment to consider inherent risks, including fraud risks, related to inventories and cost of goods sold. 2. Obtain an understanding of internal control over inventories and cost of goods sold. 3. Assess the risks of material misstatement and design tests of controls and substantive procedures that: a. Substantiate the existence of inventories and the occurrence of transactions affecting cost of goods sold. b. Establish the completeness of recorded inventories. c. Verify the cutoff of transactions affecting cost of goods sold. d. Determine that the client has rights to the recorded inventories. e. Establish the proper valuation of inventories and the accuracy of transactions affecting cost of goods sold. f. Determine that the presentation and disclosure of information about inventories and cost of goods sold are appropriate, including disclosure of the classification of inventories, accounting methods used, and inventories pledged as collateral for debt. 12-3

Inventory Methods Periodic inventory system Determine inventory quantities solely by an annual physical count Perpetual inventory records Inventory updated constantly Strong internal control over inventories May use test counts throughout the year 12-4

Functions related to inventories Purchasing Receiving Storing Issuing Processing Shipping 12-5

Controls Over the Conversion Cycle Segregation of duties over purchases and custody of inventory Use of pre-numbered requisitions, purchase orders, and receiving reports Procedures for authorizing purchase transactions and verifying them for payment General ledger control of inventories and reconciliation to production records Cost accounting controls Analysis of variances from standard costs Use of perpetual records for inventories Use of appropriate procedures for taking inventory Appropriate physical controls over inventories 12-6 1 3

Perform further audit procedures—tests of controls. 1. Examples of tests of controls: a. Examine significant aspects of a sample of purchase transactions. b. Perform tests of the cost accounting system. 2. If necessary, revise the risks of material misstatement based on the results of tests of controls. 12-7

Audit Steps (3 of 3) E. Perform further audit procedures 5. Obtain a copy of the completed physical inventory, test its clerical accuracy, and trace test counts. 6. Evaluate the bases and methods of inventory pricing. 7. Test the pricing of inventories. 8. Perform analytical procedures. 9. Determine whether any inventories have been pledged and review purchase and sales commitments. 10.Evaluate financial statement presentation of inventories and cost of goods sold, including the adequacy of disclosure. 12-9

Considerations in Planning a Physical Inventory Selecting of the appropriate date Suspending production Segregating obsolete and defective goods Establishing control over the counting process Achieving proper cutoff of sales and purchases Arranging for the services of specialists 12-10 6 7

Documentation of Physical Inventory Plan should be documented and communicated in form of written instructions to personnel taking physical inventory Letter from client reviewed by auditors Auditors consider nature and materiality of inventories Date is typically at or near balance sheet date unless internal control is effective 12-11

When the Auditors are Engaged after Year-End Inventory verification when auditor unable to observe taking of inventory at close of year. May conclude that sufficient appropriate evidence cannot be obtained to express an opinion Or could obtain satisfaction with alternative auditing procedures Existence of strong internal control Perpetual inventory records Documentation of well-planned and executed physical inventory Making of test counts 12-13

Proper Cut-off of Inventory Examine on a test basis the purchase invoices and receiving reports for several days before and after the inventory date. Determine that liability has been recorded for all goods in inventory Make sure shipments and purchases recorded in proper period 12-14

Inventory Pricing Emphasize: What method of pricing does the client use? Is the method of pricing the same as that used in prior years? Has the method selected by the client been applied consistently and accurately in practice? Test the pricing of inventories 12-15

Presentation and Disclosure Disclosure of inventory pricing methods or methods in use Other important disclosures: Changes in methods Classifications of inventory Details of pledged inventory Deduction of valuation allowance for inventory losses Existence and terms of inventory purchase commitments. 12-16

Problems with First Year Clients Procedures to obtain evidence that beginning inventory is fairly stated Review predecessor’s working papers Discuss with person who supervised physical inventory at beginning Study written instructions in planning Trace numerous items from inventory tags to final summary sheets Test perpetual inventory records for previous year Test overall reasonableness of beginning inventory 12-17
