SA 200 – Inherent Limitations and Benefits of Audit

# Inherent Limitations of an Audit & Benefits of Audit

## Why the Auditor Cannot Give Absolute Assurance

An auditor cannot reduce audit risk to zero and therefore cannot give absolute assurance. SA 200 identifies these inherent limitations:

### 1. Nature of Financial Reporting

• Preparation of FS involves management judgment (e.g., estimates, provisions) which carries inherent uncertainty.
• A precondition for the audit is that Mgt acknowledges its responsibility for preparing the FS in accordance with the AFRF and for designing such internal controls (IC) as are necessary. Even so, those controls have their own limitations and may not always produce reliable information.

### 2. Timeliness of FR & Cost-Benefit Balance

• The relevance of information decreases over time, so audit must be completed within a reasonable timeframe.
• The auditor cannot verify every transaction; a balance must be struck between reliability of information and the cost of obtaining it.
• ⚠️ However, difficulty, time, or cost alone is not a valid basis to omit an audit procedure for which there is no alternative.

### 3. Future Events

• Adverse events may affect the entity's ability to continue. The auditor's opinion does not guarantee:
• The future viability of the entity, or
• The efficiency and effectiveness of management.

### 4. Nature of Audit Procedures (Practical & Legal Limits)

• Practical — Audits use sampling; not every transaction is tested.
• Legal — The auditor cannot force management to provide information; he can only report.
• Management may be dishonest and produce fabricated documents; the auditor is not an expert in authentication of documents.
• Entity may have entered into related-party transactions that are only on paper.

### 5. Audit is Not an Investigation

Its purpose is to obtain reasonable assurance, not to uncover specific wrongdoing.

## Benefits of Audit – Why Audit is Needed

• Reviews existence and operation of controls — points out deficiencies.
• May detect fraud or error or both.
• Provides high quality information — increases user confidence that FS comply with AS.
• Acts as a moral check on employees against committing fraud.
• Safeguards shareholders' interests through independent verification.
• Useful to Government for determining tax liabilities.
• Lenders and bankers rely on audited FS for credit decisions.

## Ensuring FS are Not Misleading

Audit ensures that:

• Entries in Books of Account (BOA) are supported by Sufficient & Appropriate Audit Evidence (SAAE).
• Amounts in FS are in line with BOA entries.
• No entries in BOA are omitted.
• Information in FS is clear and unambiguous.
• Amounts are properly disclosed as per AS.
• FS present a true and fair view of results, assets, and liabilities.

## Interdisciplinary Nature of Audit

Auditing draws upon: accountancy, law, behavioural science, statistics & mathematics, economics, data processing, production, and financial management.
