1. SA 240: Fraud Triangle & Section 143(12) Reporting

Fraud is an intentional act involving deception to obtain an unjust or illegal advantage. Two types of misstatements relevant to the auditor: Fraudulent Financial Reporting and Misappropriation of Assets.

🔺 The Fraud Triangle: O-P-R Mnemonic
  • Opportunity: Absence of controls, ineffective governance, complex organizational structure, override of controls.
  • Pressure / Incentive: Financial distress, aggressive earnings targets, bonuses tied to revenue metrics.
  • Rationalization / Attitude: Justification of dishonest acts ("everyone does it", "temporary borrowing").

4. SA 299: Joint Audit Liability Matrix

Individual Liability (Divided Work) Joint & Several Liability (Shared Duties)
• Audit work allocated to the specific joint auditor in the agreed work allocation document.
• Propriety of audit procedures applied to assigned work.

⚠️ Dissenting Opinion Rule in Joint Audits

Joint auditors are NOT bound to present a unanimous opinion. If joint auditors disagree, each dissenting auditor is entitled to issue a separate audit report. The majority opinion does not bind the minority!
