Illustrative Audit Case: Keystone Computers & Networks, Inc. Part III: Substantive Tests—Accounts Receivable and Revenue This part of the audit case illustrates the manner in which the auditors design substantive tests of balances. The substantive tests are illustrated for two accounts—receivables and revenue. This aspect of the audit is illustrated with the following audit documentation: • ABC’s risk assessment working paper that combines the auditors’ assessments of inherent and control risks into an overall risk of material misstatement for the assertions. • The substantive audit program of accounts receivable and revenue. • The audit sampling plan for the conﬁrmation of accounts receivable. Adams, Barnes & Cos. assessment of control risk is described in Part II of the audit case on pages 441 through 454. To refresh your knowledge of the case, review that part as well as Part I on pages 213 through 220 of Chapter 6.
