International Auditing Standards: Evidence of Audit
Overview of International Standard on Auditing 500
- The International Standard on Auditing (ISA) 500 outlines the auditor's responsibility to design and perform audit procedures to obtain sufficient and appropriate evidence.
- Unlike other standards (200, 230, 315, 520, and 570), ISA 500 addresses all aspects related to audit evidence.
Key Definitions in Audit Evidence
- Audit evidence includes accounting records and supporting documentation such as checks, invoices, contracts, and various financial statements.
- The quality of audit evidence is determined by its relevance and reliability in supporting the auditor's conclusions regarding financial statements.
Importance of Evidence Quality
- Understanding the source, nature, and circumstances under which audit evidence is obtained is crucial for evaluating its quality.
- Sufficient evidence refers to the quantity collected during an audit; this amount is defined by the auditor based on assessed risks of material misstatement.
Procedures for Obtaining Audit Evidence
- The auditor must design procedures that ensure sufficient and appropriate audit evidence is gathered. This includes:
- Inspection of internal/external documents (paper or electronic).
- Observation of processes within the entity.
- Recalculation for mathematical verification.
Types of Audit Procedures
- Confirmation from third parties about assertions or transactions presented by the entity can be part of gathering evidence.
- Analytical procedures involve evaluating financial information through data analysis to assess risk levels effectively.
Accumulation and Reliability of Evidence
- As audits progress, auditors accumulate relevant information from accounting records and expert opinions within management.
- The reliability of audit evidence depends on its nature, source, and circumstances; it’s more reliable when sourced independently from the entity.
Selection Criteria for Testing Items
- When selecting items for testing to gather audit evidence:
- Auditors may choose specific items or use sampling methods based on situational factors affecting the audit process.
