Think of SA 240 as the standard that answers one big exam question before it's even asked: "If fraud happens in a company, is it the auditor's fault?" The short answer is — not automatically. But the auditor does have clear, specific responsibilities, and this standard defines exactly what they are.
Fraud vs. Error — the intent test. Both result in a misstatement in the financial statements, but fraud is intentional while an error is not. If Ms. Iyer, the accountant, accidentally posts ₹1,00,000 to the wrong account, that's an error. If she deliberately inflates sales by ₹5 crores to hit bonus targets, that's fraud. SA 240 deals with two types of fraud: Fraudulent Financial Reporting (FFR) — manipulating the books to mislead users — and Misappropriation of Assets (MOA) — stealing cash, inventory, or other assets. FFR is usually management-driven; MOA is often employee-level.
Primary responsibility lies with Management, not the auditor. This is a favourite exam trap. The board of directors and management are primarily responsible for preventing and detecting fraud through internal controls. The auditor's job is to obtain reasonable assurance (not absolute assurance) that the financial statements are free from material misstatement — whether due to fraud or error. Reasonable assurance means the auditor can still miss a well-concealed fraud and not be negligent, as long as proper procedures were followed.
The Fraud Triangle — your risk-assessment compass. SA 240 uses the fraud triangle to identify why fraud occurs: (1) Incentive/Pressure (management under pressure to meet earnings targets), (2) Opportunity (weak internal controls), and (3) Rationalization/Attitude (the person justifies it to themselves). The auditor uses these risk factors during risk assessment procedures to identify where fraud risk is higher. Two fraud risks are presumed always present: (a) revenue recognition risk (FFR) and (b) management override of controls (FFR). The auditor must always address these, no exceptions. Professional skepticism — maintaining a questioning mind and critically assessing audit evidence — is the key attitude SA 240 demands throughout the engagement.
