Audit Evidence — KCSE Auditing and Assurance

Gathering audit evidence is a critical component of the audit process, as outlined in International Standard on Auditing (ISA) 500. The auditor must obtain sufficient and appropriate evidence to support their conclusions. Here are key methods for gathering audit evidence:

1. Inspection: This involves examining records, documents, or tangible assets. For example, an auditor may inspect inventory records and physical stock to verify existence and condition.

2. Observation: The auditor observes processes or procedures being performed by the entity. For instance, observing the inventory counting process helps assess whether it is conducted accurately.

3. Inquiry: This method involves seeking information from knowledgeable individuals within or outside the entity. Asking management about accounting policies or procedures can provide insights into financial reporting practices.

4. Confirmation: This is obtaining a direct response from a third party to verify account balances or transactions. For example, confirming bank balances with the bank directly enhances the reliability of the evidence.

5. Recalculation: The auditor checks the mathematical accuracy of documents or records. This could involve recalculating depreciation expenses to ensure they are computed correctly according to the applicable standards.

6. Analytical Procedures: These involve evaluating financial information through analysis of plausible relationships among data. For instance, comparing current year financial ratios with prior years can highlight unusual trends that require further investigation.

Each method provides different types of evidence, and the auditor must assess the reliability and relevance of the evidence obtained to form a valid audit opinion.

Audit evidence is crucial for auditors to form their opinions on financial statements. According to International Standard on Auditing (ISA) 500, auditors must gather sufficient and appropriate evidence to support their conclusions. Sufficiency refers to the quantity of audit evidence, while appropriateness refers to its quality and relevance. Factors influencing the reliability of audit evidence include: 1. Nature of Evidence: Documentary evidence, such as contracts, is generally more reliable than oral representations. 2. Source of Evidence: Evidence obtained from independent external sources is typically more reliable than that obtained from the entity being audited. 3. Circumstances Under Which Evidence is Obtained: Evidence gathered under controlled conditions is more reliable. 4. Audit Procedures Used: The effectiveness of the audit procedures can affect the reliability of the evidence obtained. 5. Consistency with Other Evidence: Evidence that corroborates other audit findings increases its reliability. Understanding these factors is essential for auditors to evaluate the evidence effectively and ensure that it meets the standards set by ISA.
