In confirming accounts receivable on December 31, 2014, the auditor found 15 discrepancies between the customer's records and the recorded amounts in the subsidiary ledger. A copy of all confirmations that had exceptions was turned over to the company controller to investigate the reason for the difference. He, in turn, had the bookkeeper perform the analysis. The bookkeeper analyzed each exception, determined its cause, and prepared an elaborate working paper explaining each difference. Most of the differences in the bookkeeper's report indicated that the errors were caused by timing differences in the client's and customer's records. The auditor reviewed the working paper and concluded that there were no material exceptions in accounts receivable.
Two years subsequent to the audit, it was determined that the bookkeeper had stolen thousands of dollars in the previous three years by taking cash and overstating accounts receivable. In a lawsuit by the client against the public accountant, an examination of the auditor's December 31, 2014, accounts receivable working papers, which were subpoenaed by the court, indicated that one of the explanations in the bookkeeper's analysis of the exceptions was fictitious. The analysis stated the error was caused by a sales allowance granted to the customer for defective merchandise the day before the end of the year. The difference was actually caused by the bookkeeper's theft.
