Understanding Audit Evidence
Definition and types of audit evidence
Auditing evidence refers to the information collected for the review of a company’s financial transactions and internal control practices. It includes various types such as documentation, records, and events used by auditors to form opinions on financial statements.
The role of audit evidence in the audit process
The role of audit evidence in the audit process is crucial as it supports and corroborates management’s assertions regarding financial statements or internal controls. It provides the necessary information for the certification of financial statements as being fairly represented.
The concept of reliability in audit evidence
The reliability of audit evidence depends on the nature and source of the evidence and the circumstances under which it is obtained. For instance, evidence obtained from knowledgeable and independent sources is generally more reliable than evidence obtained solely from internal company sources.
| Type of Audit Evidence | Reliability |
|---|---|
| Documentation | High |
| Physical Observations | High |
| Conflicting | Low |
Remember, while drawing conclusions from audit evidence, it is essential to ensure that it is both relevant and reliable in supporting the auditor’s opinion.
These responses should give a better understanding of audit evidence, its types, the significance of audit evidence in the audit process, and the concept of reliability.
Factors Affecting Reliability of Audit Evidence
Nature and source of evidence
The nature and source of evidence play a crucial role in its reliability. For example, financial statements directly from a company’s accounting system are more reliable than unaudited information from management.
Objectivity and independence of the evidence
The objectivity and independence of the evidence are critical factors. For instance, evidence provided by a neutral third party, such as a bank statement or a confirmation from a third-party vendor, is more reliable than evidence provided by internal sources with potential biases.
Timeliness of the evidence
The timeliness of evidence also affects its reliability. For example, recent bank statements or real-time transaction records hold higher reliability compared to older data that may be subject to changes or manipulation.
| Factor | Example |
|---|---|

| company’s accounting system. | |
| Objectivity and independence | Evidence provided by a neutral third |
| party, such as a bank statement. | |
| Timeliness of the evidence | Recent bank statements or real-time |
| transaction records. |
Types of Audit Evidence
Documentary evidence
Documentary evidence, a crucial type of audit evidence, encompasses records and tangible documents used for verification. These documents can include ledgers, journals, invoices, contracts, and financial statements from the accounting information system of the entity.
For instance, invoices can serve as documentary evidence to validate the occurrence of transactions.
Physical evidence
Physical evidence in auditing involves the direct inspection of tangible assets such as inventory, machinery, or documents to verify their existence, condition, or ownership. For example, physically examining inventory or machinery on-site provides direct evidence supporting audit assertions about their existence and valuation.

Remember, the correctness and reliability of your evidence can make or break the success of your audit process!
Methods of Obtaining Reliable Audit Evidence
Observation
Observation can provide audit evidence about the performance of a process or procedure. However, its reliability is limited to the specific point in time of the observation.
Additionally, it’s crucial to recognize that the act of being observed may influence how the process or procedure is carried out.
Inquiry
Inquiry involves obtaining information from knowledgeable parties within the organization. While this can yield valuable audit evidence, it’s important to note that the reliability of this evidence depends on the competence and responsiveness of the individuals providing the information.
Inspection
Inspection of records and documents is another method to gather reliable audit evidence. The degree of reliability varies based on the nature and source of the records, as well as the effectiveness of controls over their production.
Confirmation
Confirmation represents a formal correspondence with a third party to verify information or balances. This is a highly reliable method of obtaining audit evidence as it involves direct communication with external sources.
| Method | Reliability |
|---|---|
| Observation | Limited |
| Inquiry | Dependent |
| Inspection | Varied |
| Confirmation | Highly reliable |
