Information misrepresentation involves the intentional misstatement or omission of important information in the financial reports to deceive users of those reports. In this scenario, the sales director's failure to correct the reserves for unearned income in the department's performance report, despite knowing it should be adjusted for cancellations, is a clear example of information misrepresentation. This act could lead to misleading stakeholders about the company's financial status, which fits the definition of information misrepresentation fraud.

Due professional care was applied by the internal auditor. According to IIA guidance, due professional care involves applying reasonable judgment in all audit circumstances. The auditor's decision to extend the scope of testing based on a fraud risk assessment, even though no issues were initially found, represents a judicious use of professional judgment given the potential risk of fraud. The fact that fraud was later discovered does not necessarily imply a lack of professional care, as audits cannot guarantee the detection of all frauds.

When the Chief Audit Executive (CAE) reports to the Chief Financial Officer (CFO), there is a potential risk of impairing the independence and objectivity of the internal audit function. This reporting relationship might limit the scope of audit engagements, especially in areas that could affect the CFO, such as financial reporting or other areas directly under the CFO's control. The CAE should ideally report functionally to the board or audit committee to maintain independence, as suggested by The IIA standards.
IIA Standard 1110: "Organizational Independence"

To determine the magnitude of risk events, organizations commonly assess both the potential impact of the risk event and its likelihood of occurrence. Impact refers to the extent of the consequences if the risk were to materialize, while likelihood refers to the probability of the risk event occurring. Together, these factors help in quantifying and prioritizing risks, enabling more effective risk management decisions.
Tolerance and appetite (A) are related to the organization's willingness to accept certain levels of risk, not directly to assessing the magnitude of specific risk events. Inherent and residual risk (B) describe risk levels before and after controls are applied, respectively. Cost and benefit (C) pertain to evaluating the financial implications and potential returns of risk management strategies.
