Auditing Principles - CH 12 - Inventories and Cost of Goods Sold

  1. The Special Significance of Audit of Inventories
    ØThe valuation of goods on hand and in process often presents complex and difficult issues

    ØDetermining the quantities of inventories may require specialized techniques

    ØInventories often represent the largest current asset of a company

    ØMisstatements of inventories directly affect cost of goods sold and, therefore, net income

    ØManagement fraud has often involved the fraudulent overstatement of inventories
  2. Source of Inventories

    • lGoods on hand ready for sale
    • lGoods in the process of production
    • lGoods to be consumed directly or indirectly in production such as raw materials, purchased parts and supplies
  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.
