## Scope of Audit

### What IS Included in Audit Scope

#### 1. Coverage of All Aspects of the Entity

The audit must be organized to cover all aspects of the entity relevant to the FS being audited.

#### 2. Reliability and Sufficiency of Financial Information

Auditor must be reasonably satisfied that underlying accounting records and source data (bills, vouchers, documents) are reliable and sufficient
Achieved by:
Studying and assessing accounting systems and Internal Controls (IC)
Carrying out appropriate tests, enquiries, and procedures

#### 3. Proper Disclosure of Financial Information

Auditor decides whether relevant information is properly disclosed in FS
Considers applicable statutory requirements
Ensures FS properly summarize transactions/events
Evaluates management's judgments in preparation of FS
Assesses selection and consistent application of accounting policies (period-to-period basis)

#### 4. Expression of Opinion on FS

The culmination of scope — forming and communicating the audit opinion.

### What is NOT Included in Audit Scope

Exclusion	Reason
Duties outside auditor's competence	e.g., assessing physical condition of machinery or civil structures — requires engineers
Authentication of documents	Auditor is not a forensic document expert; cannot verify genuineness of documents
Official investigation into alleged wrongdoing	Auditor lacks legal powers (search, recording statements on oath) needed for investigations
Preparation and presentation of FS	This is management's responsibility, not the auditor's

### Audit vs. Investigation — Key Contrast

Feature	Audit	Investigation
Objective	Express opinion on FS	Specific purpose (e.g., detect fraud)
Scope	General and broad	Specific and narrow
Legal powers	None	May have specific powers
Trigger	Statutory / voluntary	Specific suspicion or mandate

Worked example

### Example 1

A factory has heavy machinery worth ₹10 crores on the balance sheet. The auditor cannot determine the physical condition or remaining useful life of the machinery — that requires a qualified engineer. The auditor can verify cost, depreciation calculations, and whether the asset is in use, but not its technical condition.

### Example 2

Management submits a board resolution as evidence of a key authorization. The auditor checks whether it exists and appears on its face to be genuine — but cannot authenticate the signatures or paper as a forensic expert would. This is outside audit scope.

⚠️ Common exam mistakes

Thinking auditors must verify genuineness of all documents — they check existence and apparent consistency, not forensic authenticity
Assuming audit scope includes investigating fraud once suspected — investigation is separate from audit and requires specific mandate and legal powers
Forgetting to mention 'consistent application of accounting policies' when discussing proper disclosure — examiners look for this
Treating the four inclusions as a flat list — understand that reliability/sufficiency (point 2) is the foundation, and disclosure (point 3) builds on it
