Past Questions

AI Explanation

**The reasoning** Audit risk is a *technical term* in auditing. It means the risk that an auditor gives the **wrong opinion** on financial statements. Think about it: an auditor's main job is to say whether company accounts are "true and fair" or not. The biggest professional disaster? Saying accounts are fine when they're actually dodgy (or vice versa). That's expressing an **inappropriate opinion** — getting your professional judgment wrong when it matters most. This concept appears in auditing standards worldwide, including the standards Nigerian accountants follow. **Why the wrong options tempt you** - **A (Fired)**: That's a *consequence* of audit risk, not the risk itself. You're thinking too practically instead of technically. - **C (Forgets paperwork)**: That's just administrative sloppiness, not the core professional risk. - **D (Charges too little)**: That's a business/pricing problem, nothing to do with audit quality. They all sound like "bad things that could happen," but only B captures the *professional definition*. **Quick takeaway** Audit risk = the chance your professional opinion is **wrong** — always think "opinion quality," not personal consequences.

AI Explanation

**The reasoning** Auditor independence is a *fundamental ethical principle* in accounting. When an auditor examines a company's financial statements, they must be completely unbiased — not influenced by money, friendship, or pressure. This ensures their report is truthful and reliable. Independence isn't about calculating costs or following tax procedures; it's about *professional integrity* and *trust*. That's why it falls squarely under **ethical standards** like those in the ICAN Code of Ethics or international frameworks (IFAC). **Why the wrong options tempt you** - **A (Cost rules)** tricks you because audits do cost money, but independence is about *behavior*, not pricing. - **C (Tax law)** might seem related since auditors handle financial matters, but tax law governs tax payments, not auditor conduct. - **D (Sales rules)** has nothing to do with auditing — it's a distractor for rushed students. **Quick takeaway** Independence is the auditor's **ethical shield** — it protects the public from fraudulent reports, so it lives in ethical standards, not operational rules.

AI Explanation

**The reasoning** Materiality is a fundamental accounting principle that asks: "Does this information **matter** to someone making a decision?" Think of it like this: If you're buying a house and the seller hides the fact that the roof leaks badly, that's **material** — it would definitely change your decision to buy or how much you'd pay. But if they forgot to mention a tiny scratch on a back door? Not material — wouldn't change your choice. In accounting and financial reporting, information is material if leaving it out or getting it wrong would influence users (investors, managers, creditors) when they're deciding whether to invest, lend money, or take action. It's about **relevance and impact**, not age or cost. **Why the wrong options tempt you** - **A (Cheap)** — You might confuse "material" with "immaterial" (unimportant/cheap), but they're opposites in accounting context - **C (Old)** & **D (Long)** — These relate to physical properties or time, not accounting concepts **Quick takeaway** Material = "Would this info change my decision?" If yes, it matters — disclose it!

AI Explanation

ISA 200: the auditor's objective is reasonable assurance and an opinion on whether the financials are free of material misstatement.

AI Explanation

Unqualified opinion is the best outcome — financials are fairly presented in all material respects.

AI Explanation

Materiality is judged by quantitative and qualitative factors that could affect user decisions.

AI Explanation

Inherent risk = susceptibility of assertion to misstatement before considering controls. One leg of audit-risk model.

AI Explanation

AR = IR × CR × DR. Auditor manages DR (via amount/timing of work) to keep AR acceptably low.

AI Explanation

ISA 500 procedures: inspection, observation, inquiry, confirmation, recalculation, re-performance, analytical procedures.

AI Explanation

Tests of controls evaluate whether controls operated effectively — supports reliance on those controls.

AI Explanation

Substantive procedures address assertions — external confirmation verifies existence/value of receivables.

AI Explanation

ISA 210: engagement letter formalises the audit's terms before fieldwork.

AI Explanation

Long association reduces professional scepticism; IESBA mandates partner rotation after a defined period.

AI Explanation

IAS 1 / ISA 570: accounts prepared on going-concern basis unless intent/necessity to cease.

AI Explanation

ISA 560 requires the auditor to consider events between year-end and report date and ensure proper IAS 10 treatment.

AI Explanation

COSO 2013: Control Environment, Risk Assessment, Control Activities, Information & Communication, Monitoring (5).

AI Explanation

Splitting authorisation/recording/custody prevents errors and fraud before they occur — a preventive control.

AI Explanation

Walkthroughs verify the auditor's documented understanding of controls matches actual operation.

AI Explanation

ISA 530: audit sampling lets the auditor draw conclusions from less than 100% testing while giving every item a chance of selection.

AI Explanation

ISA 701 requires KAMs in listed-entity audit reports — matters that were of most significance in the audit.

AI Explanation

ISA 705: qualified opinion is used where misstatements are material but not pervasive.
