Audit Evidence
Audit evidence is the information used by the auditor to determine whether the financial statements are prepared in accordance with the applicable financial reporting framework. This includes both documentary evidence (e.g., invoices, contracts) and corroborative evidence (e.g., confirmations from third parties).
Types of Audit Evidence
There are two main types of audit evidence: documentary and corroborative. Documentary evidence includes financial records, contracts, and invoices. Corroborative evidence includes confirmations from third parties, such as bank statements and customer confirmations.
Example: An auditor may request bank statements and confirmation letters from a company's bank to verify the accuracy of cash balances reported in the financial statements.
Sufficient and Appropriate Evidence
Sufficient evidence means that the amount of evidence gathered is enough to support the auditor's conclusions. Appropriate evidence means that the evidence is relevant and reliable. The auditor must balance the need for sufficient evidence with the cost and practicality of obtaining it.
Example: To verify accounts receivable, an auditor may send confirmation requests to a sample of customers. The number of confirmations sent must be sufficient to provide a reliable basis for the auditor's conclusion, but not so many that the cost outweighs the benefit.
Audit Procedures
Audit procedures are the specific actions taken by the auditor to gather evidence and evaluate the assertions made in the financial statements. These procedures can include tests of controls, substantive tests of transactions, and analytical procedures.
Example: The auditor may perform a test of controls by observing employees processing cash receipts to assess the effectiveness of the company's cash handling procedures.
Evaluation of Audit Evidence
The evaluation of audit evidence involves assessing the reliability and relevance of the evidence gathered. The auditor must consider the source of the evidence, the nature of the information, and any limitations or biases that may affect its reliability.
Example: If an auditor receives conflicting information from different sources, such as the company's records and a third-party confirmation, the auditor must evaluate the reliability of each source to determine the appropriate course of action.
Examples and Analogies
Consider audit evidence as "pieces of a puzzle," where each piece (evidence) helps the auditor form a complete picture of the financial statements. Sufficient and appropriate evidence is like having enough high-quality pieces to complete the puzzle accurately.
Audit procedures are the "tools" the auditor uses to gather these pieces, similar to the instruments a detective uses to collect clues. The evaluation of audit evidence is akin to "analyzing the clues" to determine their reliability and relevance.
