2. 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

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.
