Materiality in Audits and Reviews

Materiality is a fundamental concept in audit and review engagements performed by CPA firms. It refers to the importance of financial information and the impact that it can have on a user’s decision-making process. In other words, materiality is the magnitude of an omission or misstatement of financial information that can influence the decision of an informed user of the financial statements. It is an important factor that auditors and reviewers consider when assessing the accuracy and completeness of financial statements.


In the context of an audit or review, materiality is used to determine the scope and nature of the procedures that auditors or reviewers perform. In review engagements, materiality is typically determined at only one level, which is the level of overall materiality for the financial statements as a whole. In audit engagements, materiality is evaluated at two levels: overall materiality and performance materiality.


Overall materiality is the maximum amount of misstatement that can be considered immaterial to the financial statements as a whole. It is usually determined as a percentage of a benchmark such as net income, total assets or total revenues. The determination of overall materiality requires professional judgment and considers various factors such as the nature of the client’s business, the regulatory environment and the user’s needs for the financial statements. The concept of overall materiality in an audit is essentially the same concept that is applied in review engagements that is simply referred to as materiality.


Performance materiality is the amount set by the auditor to reduce the risk of material misstatements to an acceptable level. It is a lower amount than overall materiality and can be applied to individual account balances, classes of transactions or disclosures. Performance materiality ensures the audit procedures are targeted at areas of the financial statements where there is a higher risk of material misstatements.


Materiality is a critical component of the audit and review process because it helps auditors and reviewers focus on areas of the financial statements that are most likely to contain material misstatements. It also helps auditors and reviewers determine the nature, timing and extent of the audit or review procedures required to ensure that the financial statements are free from material misstatements.
