A problem with positive confirmations is poor response rate. Customers who do not dispute the Negative confirmations request the recipients to respond only if they disagree with the amount shown in the letter. This technique is used primarily when accounts receivable consist of a large number of low-value balances and the control risk of misstatement is considered to be low. The sample size for this type of test is typically large and may include the entire population. Evidence from nonreturned negative confirmations selected from a large population provides indirect evidence to support the auditor’s expectation that accounts receivable are not materially misstated.
