      SCOPE

      While AU-C 450 contains guidance on how to use materiality when evaluating the effect of identified misstatements, AU-C 320 offers auditors guidance in using materiality when planning and performing the audit. (AU-C 320-01)

      NOTE: The auditor may want to consider the guidance provided in the SEC’s Staff Accounting Bulletin (SAB) 99, Materiality. This SAB addresses the application of materiality thresholds to the preparation and audit of financial statements filed with the SEC and provides guidance on qualitative factors to consider when evaluating materiality.

      DEFINITION OF TERM

      Source: AU-C 320.09. For the definition related to this standard, see Appendix A, “Definitions of Terms”: Performance materiality.

      OBJECTIVE OF AU-C SECTION 320

      The objective of the auditor is to apply the concept of materiality appropriately in planning and performing the audit.

      (AU-C Section 320.08)

      OVERVIEW

      The FASB’s Conceptual Framework Concept No. 8 says that:

      The omission or misstatement of an item in a financial report is material if, in light of surrounding circumstances, the magnitude of the item is such that it is probable that the judgment of a reasonable person relying upon the report would have been changed or influenced by the inclusion or correction of the item.

      This definition is consistent with the definition used by the SEC, the PCAOB, the AICPA, and the U.S. judicial system.

      Materiality is entity-specific and is based on the nature and/or magnitude of the item in the context of an individual entity’s financial report. Thus, materiality is influenced by the auditor’s perception of the needs of financial statement users who will rely on the financial statements to make economic decisions. (AU-C 320.04) Specific needs of users may vary widely, and those are not considered.

      Materiality and Audit Risk

      Audit risk is the risk that the financial statements are materially misstated and the auditor expresses an inappropriate audit opinion. The auditor must perform the audit to reduce audit risk to a low level. Audit risk is a function of two components:

      1 Risk of material misstatement, which is the risk that the financial statements are materially misstated prior to the audit, and

      2 Detection risk, which is the risk that the auditor will not detect such misstatements.

      The model AR = Risk of material misstatement (RMM) × Detection risk (DR) expresses the general relationship of audit risk and the risks associated with the auditor’s assessment risk of material misstatement (inherent and control risks) and detection risk. (AU-C 320.A1)

      Reducing audit risk to a low level requires the auditor to:

      1 Assess the risk of material misstatement and, based on that assessment,

      2 Design and perform further audit procedures to reduce overall audit risk to an appropriately low level.

      The auditor must consider materiality and audit risk during the audit, especially when:

       Determining the nature and extent of risk assessment procedures

       Identifying and assessing the risks of material misstatements

       Determining the nature, timing, and extent of further audit procedures

       Assessing the effect of uncorrected misstatements on the financial statements and auditor’s opinion

      (AU-C 320.A1)

      REQUIREMENTS

      Determining Materiality and Performance Materiality

      Making a Judgment about Materiality When Planning the Audit

      When making a judgment during the planning phase about the amount to be considered material to the financial statements, the auditor should first recognize the nature of this amount. It is an allowance or “cushion” for undetected or uncorrected misstatements remaining in the financial statements after all audit procedures have been applied. The auditor’s goal is to plan audit procedures so that if misstatements exceed this amount, there is a relatively low risk of failing to detect them.

      It is usually efficient and effective to estimate a single dollar amount to be used in planning the audit. Since the amount is to be used as an aid in planning the scope of auditing procedures, use of a general benchmark is both practical and acceptable. (AU-C 320.A5) For example, many auditors use 5% to 10% of before-tax income or 0.5% to 1% of the larger of total assets or total revenues. Adoption of a benchmark requires consideration of the appropriate base and the percentage of that base to be used to make the calculation.
