IIA-CIA-Part2 Exam Dumps - Practice of Internal Auditing

When developing the work program for an engagement reviewing an organization’s small contracting services, the chief audit executive (CAE) should consider the organization's recent changes to how it processes payments. Changes in payment processing can significantly impact the control environment and may introduce new risks or control gaps. Understanding these changes will help the CAE design appropriate audit procedures to evaluate the effectiveness of the controls over the new processes.

Step-by-Step Detailed Explanation:

A. The decision affects the test procedures performed:Correct. The choice between statistical and nonstatistical sampling affects the design of the sample selection, execution of audit procedures, and the nature of conclusions drawn. Statistical sampling involves probabilistic techniques that influence sample size and evaluation, whereas nonstatistical sampling relies on auditor judgment.

B. The auditor's response to errors detected will be influenced:While error response is critical, it is influenced more by the nature and materiality of the errors than by the sampling approach.

C. The competence of the evidence obtained is greater with statistical sampling:This is incorrect because the competence of evidence depends on the procedure itself, not the sampling method used. Both methods can yield competent evidence if applied correctly.

D. Nonstatistical sampling may be more cost effective:While this can sometimes be true, it is context-dependent and not universally applicable, so it is not the best answer.

A properly supervised engagement ensures that the audit is conducted effectively, efficiently, and in accordance with IIA standards. The auditor in charge has the responsibility to oversee the audit process and ensure that the engagement objectives are achieved.

IIA Standard 2340 – Engagement Supervision:

This standard requires that engagements be supervised to ensure that objectives are achieved, work is performed according to appropriate standards, and the results are supported by sufficient, relevant, and reliable evidence.

Reasonable Assurance:

The auditor in charge must provide reasonable assurance that the audit engagement's objectives were met. This involves reviewing work performed, ensuring compliance with audit standards, and verifying that conclusions are supported by adequate evidence.

IIA Practice Advisory 2340-1:

The advisory emphasizes the role of the auditor in charge in providing oversight throughout the audit engagement. This includes ensuring that auditors follow procedures, apply professional judgment, and that all significant findings are appropriately addressed.

Option A (Daily record review): While keeping a record is good practice, it does not constitute comprehensive supervision.

Option B (Review by peers): Peer review is useful but does not replace the overarching responsibility of the auditor in charge.

Option C (Accompanying new auditors): This is part of training and guidance but does not alone ensure that engagement objectives are met.

Detective controls are designed to identify and detect errors or fraud after they have occurred. Receipts for employee expenses serve as a detective control by providing evidence of transactions, enabling verification and review of expenses to identify any fraudulent or unauthorized activities. Awareness of prior incidents of fraud (Option A) is more of a preventive control, contractor non-disclosure agreements (Option B) are preventive controls to mitigate risks of information leakage, and verification of currency exchange rates (Option C) is more of a transaction control.

An internal audit procedures manual typically includes detailed information on the methodologies, tools, and techniques used during audits. It also outlines the protocols and guidelines for auditors to follow, including their authority and the scope of their work. Clearly defining the extent of the auditor's authority to collect data from management ensures that auditors understand their rights and limitations, which is essential for carrying out effective and efficient audits.References:

Step-by-Step Detailed Explanation:

A. To provide a status update on a short engagement to management of the area under review and to the audit supervisor:While useful, this is not the primary purpose of issuing interim reports.

B. To confirm agreement with preliminary observations and conclusions identified during the engagement:Interim reports are not primarily for reaching agreement but for prompt communication of actionable items.

C. To provide those responsible for the area under review with the opportunity to act on certain observations immediately:Correct. Interim reports are issued when there are observations that require immediate action or management’s attention before the final report is issued.

D. To verify that the corrective actions required by senior management are completed as agreed:Verifying corrective actions occurs after final recommendations are implemented, not through interim reporting.

Discovery sampling is a statistical sampling method that is specifically designed for detecting fraud or other irregularities. It is most appropriate when the auditor expects that deviations or fraud may be rare but significant if found.

Discovery Sampling:

Discovery sampling is used when the auditor is trying to identify at least one occurrence of a particular event, such as fraud. The sample is designed so that if a single error is found, it suggests that more may exist within the population, warranting further investigation.

Application in Fraud Detection:

Discovery sampling is effective in fraud detection because it focuses on identifying whether any instances of fraud exist within a population. This approach is well-suited for situations where even a small number of fraudulent transactions could have a significant impact.

IIA Practice Guide on Statistical Sampling:

The IIA suggests that discovery sampling is appropriate when the goal is to find the presence of an error or fraud, particularly in populations where such occurrences are expected to be infrequent.

Option B (Stop-or-go sampling): This method is used to control the risk of over-auditing when errors are expected to be low, but it is not specifically designed for fraud detection.

Option C (Haphazard sampling): This is a non-statistical sampling method and is not appropriate for systematic fraud detection.

Option D (Stratified attribute sampling): This method divides the population into subgroups but is not specifically aimed at discovering fraud.

Detailed Explanation:Why Not Other Options?Conclusion: Option A is correct because discovery sampling is the most appropriate statistical method for testing a population for fraud, as it is designed to detect even a small number of significant deviations, consistent with IIA guidance.
