An auditor is performing a review of a client's significant accounting estimates, specifically the allowance for doubtful accounts. Which of the following approaches is generally considered the most persuasive and independent method for auditing such an estimate?
- AReviewing and testing management's process for developing the estimate.
- BConfirming the collectibility of a sample of large accounts receivable balances with customers.
- CDeveloping an independent expectation of the estimate for comparison to management's estimate.
- DObtaining a written representation from management regarding the reasonableness of the estimate.
Show answer & explanationAnswer & explanation
Correct answer: C. Developing an independent expectation of the estimate for comparison to management's estimate.
Developing an independent expectation of an estimate and comparing it to management's estimate is generally the most persuasive approach. This method provides the auditor with an independent benchmark against which to evaluate management's judgment, reducing the risk of management bias and enhancing the auditor's objectivity.
Why the other options are wrong
- A. Reviewing management's process is a good approach but relies on management's inputs and assumptions; it is less independent than developing a separate estimate.
- B. Confirming collectibility of specific accounts is useful for testing individual balances, but it does not provide an overall assessment of the allowance for doubtful accounts, which is an estimate for the entire population.
- D. Written representations are corroborative evidence and do not provide independent evidence of the reasonableness of the estimate itself.
Auditing Accounting Estimates Approaches
Auditing accounting estimates involves evaluating the reasonableness of management's judgments in areas that are inherently uncertain. Auditors can use three main approaches: reviewing management's process, developing an independent estimate, or reviewing subsequent events.
- Accounting estimates involve high inherent risk due to subjectivity and complexity.
- Developing an independent estimate is generally the most robust approach.
- The auditor must consider management's assumptions, data, and methods used.
- Subsequent events can provide corroborating evidence for estimates.
Memory trick: To AUDIT estimates, an INDEPENDENT benchmark is BEST for JUDGMENT.
