Which of the following conditions is the most likely indicator of fraud?

A manager who regularly assumes the duties of their subordinates is a significant behavioral red flag for fraud. This action directly undermines the fundamental internal control principle of segregation of duties. By performing tasks that should be separated (e.g., authorization, custody of assets, and record-keeping), the manager creates an opportunity to both perpetrate and conceal fraudulent acts. This circumvention of controls is a classic method for management to override the established control system, making it the most likely indicator of fraud among the options provided.

A. Paying commissions on verified sales is a strong internal control designed to prevent fraud, not an indicator that it is occurring.
B. Consistently untimely reports are more commonly an indicator of operational inefficiency or inadequate resources rather than a direct sign of fraud.
D. A company's earnings falling in line with a broader industry downturn is a normal and expected economic event, not a fraud symptom.

1. COSO. (2013). Internal Control—Integrated Framework: Principles. Principle 10: "The organization selects and develops control activities that contribute to the mitigation of risks... Control activities include... Segregation of Duties." A manager assuming subordinate duties directly violates this principle, creating a significant control weakness and fraud opportunity.

2. The Institute of Internal Auditors (IIA). (2017). International Standards for the Professional Practice of Internal Auditing (Standards). Standard 2120.A2 requires internal audit to evaluate fraud potential and risk management. The associated Implementation Guide discusses fraud red flags, which include management override of controls and behavioral signs like a manager who insists on performing tasks that should be delegated.

3. Albrecht, W. S., Albrecht, C. O., Albrecht, C. C., & Zimbelman, M. F. (2019). Fraud Examination (6th ed.). In the chapter on "Recognizing the Symptoms of Fraud," the text identifies internal control weaknesses as a primary category of fraud symptoms. A key example provided is the lack of segregation of duties, which is precisely what occurs when a manager performs their subordinates' tasks. This behavior is listed as a classic red flag.
