IIA IIA-CIA-Part2 - Practice of Internal Auditing

Probability-proportional-to-size (PPS) sampling, also known as monetary unit sampling, is most appropriate for measuring the total misstatement in an accounts payable ledger. This method is used to determine the likelihood of individual items being selected based on their size, with larger items having a higher probability of being selected. This is particularly useful in identifying overstatements and misstatements in financial records, such as accounts payable, where the monetary value of transactions is a critical factor.

Institute of Internal Auditors (IIA), Practice Guide – Auditing Sampling.

According to IIA guidance, an appropriate role for the internal audit activity with regard to the organization's risk management program is to attain an adequate understanding of the organization's key risk mitigation strategies. This enables internal auditors to evaluate the effectiveness of risk management processes and provide assurance on the adequacy of risk controls. Identifying and managing risks, ensuring risk management processes exist, and ensuring controls exist to mitigate risks are responsibilities of management, not internal audit.

IIA Practice Guide: Internal Audit's Role in Risk Management

In internal auditing, the reliability of evidence is critical. According to IIA standards, evidence that is obtained directly from an external source, such as a customer, is generally considered more reliable, especially when it is timely.

IIA Standard 2310 – Identifying Information:

This standard requires that internal auditors obtain sufficient, reliable, relevant, and useful information to achieve the engagement’s objectives. Evidence obtained directly from external sources is often deemed more reliable because it is less likely to be biased or manipulated.

Direct Evidence:

Evidence obtained directly from a customer is considered highly reliable because it comes from an independent and external party. It is less likely to be influenced by internal pressures or conflicts of interest.

Timeliness:

The timeliness of evidence also affects its reliability. Recent and relevant information is more likely to accurately reflect the current state of affairs, making it more reliable for decision-making.

Option A (Untested third party): Although external, the reliability of evidence from an untested third party is uncertain until their credibility is established.

Option B (Uncorroborated evidence from an employee): This is less reliable as it may be subject to bias or self-interest.

Option C (Undocumented evidence from a manager): Undocumented evidence is generally less reliable as it lacks supporting documentation that can be verified.

Detailed Explanation:Why Not Other Options?

The chief audit executive (CAE) is responsible for the approval of the engagement objectives and scope in internal auditing. While senior management, the head of customer service, and the board of directors may provide input and have interests in the audit engagement, it is ultimately the CAE who has the final authority to approve the objectives and scope. This ensures that the internal audit activity remains independent and that the engagement aligns with the overall audit plan and organizational priorities.

The Institute of Internal Auditors (IIA) Standard 2010 - Planning

IIA Standard 2200 - Engagement Planning

At the planning stage, auditors must organize and structure their work to ensure all necessary steps are covered. A checklist is the appropriate tool, as it provides a systematic list of tasks, reduces oversight, and helps manage workload. A control questionnaire (C) is used for assessing controls, and a fishbone diagram (D) is used for root cause analysis, not task management. Option A is irrelevant to planning execution.

ï‚· Investment Portfolio Terms:

Cash Cow: A business unit with a dominant market position in a mature, slow-growth industry that generates consistent positive cash flow and profits. It requires little investment to maintain its market position and provides funds for other investments.

Star: A business unit with a high market share in a fast-growing industry. It requires significant investment to maintain its position and support further growth.

Question Mark: A business unit with a low market share in a high-growth industry. It requires substantial investment to increase market share.

Dog: A business unit with a low market share in a slow-growth industry, generating minimal profit or loss.

ï‚· Characteristics of a Cash Cow:

Dominant Position: The acquired organization has a strong market position.

Mature Industry: The industry is mature with slow growth.

Positive Financial Income: Consistently generates positive cash flow and profits, requiring minimal investment.

ï‚· Investment Strategy:

Portfolio Management: Investors typically use cash cows to fund other investments, maintaining a balanced portfolio that supports growth while providing stable returns.

ï‚· References:

The term "cash cow" accurately describes an organization with a dominant position in a mature, slow-growth industry that consistently generates positive financial income, fitting the investor’s description​​​​.

ï‚· IIA Standards on Fraud:

Standard 2120 – Risk Management: Internal auditors must evaluate the potential for the occurrence of fraud and how the organization manages fraud risk.

Immediate Response: When evidence of fraud is discovered, the internal auditor must ensure that appropriate actions are taken promptly.

ï‚· Next Steps for Internal Auditor:

Consult with Supervisor: The internal auditor should discuss the findings with the engagement supervisor. This ensures that the situation is assessed by a more experienced individual who can determine the next steps, including the need for specialized fraud investigation resources.

Specialized Expertise: Determining whether fraud investigation experts are needed is crucial for handling the matter appropriately, as they possess the necessary skills to investigate complex fraud cases.

ï‚· Documenting Evidence:

While documenting the evidence and recommending controls is important (Option C), the immediate step should involve consultation with the supervisor to decide on the investigation approach.

Notifying management directly (Option A) or law enforcement (Option D) should follow internal protocols and often occur after consultation with the supervisor and possibly higher-level approvals.

ï‚· References:

Engaging the engagement supervisor ensures that the appropriate steps are taken to investigate the fraud properly, aligning with professional standards and ensuring a thorough investigation​​​​.

According to IIA guidance, the chief audit executive (CAE) should maintain independence and objectivity in their role. While the CAE can manage and coordinate risk management processes, audit those processes, and be involved in risk oversight committees, they should not accept management's responsibility for risk management without the board's approval. This ensures that there is no conflict of interest and maintains the CAE's independence. References:

According to Standard 2330 – Documenting Information, only information that is sufficient, relevant, and supports engagement results should be retained in workpapers. Since the workpapers already contain sufficient evidence, additional notes that do not add value should not be included. Option B is correct: omit unnecessary notes from the workpapers.

In the five-attribute approach to documenting deficiencies, the attribute that answers the question "What should be in place?" is Criteria. Criteria represent the standards, measures, or expectations used in making an evaluation and/or verification (what should be). It defines what the process or control should achieve, serving as a benchmark against which the actual condition (what is) is compared. The criteria are essential for identifying deviations and determining the nature and significance of deficiencies.

IIA's International Standards for the Professional Practice of Internal Auditing, Standard 2410 – Criteria for Communicating.

According to Standard 2210 – Engagement Objectives, objectives must be established for each engagement and should reflect a preliminary risk assessment. Findings (A) come after testing, resources (B) are allocated later, and the audit plan (D) applies at the annual activity level. Thus, the correct answer is audit objectives (C).

Direct observation by the auditor provides the strongest and most reliable evidence of inventory existence, per IIA Standard 2310: Identifying Information. Observational evidence is primary and directly verifiable, whereas third-party confirmations (Option B) or photographs (Option D) may be manipulated. Interviews with personnel (Option C) provide insight but lack objectivity and reliability compared to physical observation. This aligns with the CIA syllabus emphasis on collecting sufficient and appropriate audit evidence (Part 2: Section II).

Broad legislative reforms present the most critical external risk to an organization because they can fundamentally change the regulatory environment in which the organization operates. Such changes can impact compliance requirements, operational processes, and strategic planning. The organization must quickly adapt to remain compliant and avoid penalties or legal issues. This type of risk is external and largely uncontrollable, making it particularly critical compared to internal changes or new market entries.

An internal control questionnaire (ICQ) is a tool used by auditors to gather detailed information about the internal control system of an audited area. The primary purpose of an ICQ is to identify and assess risks that could prevent the area from achieving its objectives. By systematically covering various control points, the questionnaire helps the auditor evaluate the adequacy and effectiveness of controls in place and identify areas where controls may be lacking or need improvement.

The Institute of Internal Auditors (IIA) - Practice Guide: Internal Control Questionnaire

Flat structures reduce hierarchical layers, increasing spans of control. With fewer supervisors overseeing more employees, the time and ability for supervision becomes limited, which is a control weakness.

Option A refers to innovation, not control implications.

Options C and D describe hierarchical or vertical structures, not flat ones.

Thus, the control implication of a flat structure is limited supervision availability (Option B).
