Materiality

Materiality Case Example: ABC Manufacturing Company

Context

Given the scale and complexity of ABC Manufacturing Company’s operations, establishing materiality levels is crucial for effectively allocating audit resources and identifying areas where financial information could be materially misstated.

Audit Objective

To establish and apply materiality levels that are reasonable in identifying misstatements that could individually or in aggregate affect the economic decisions of users of the financial statements.

Types of Audit Evidence and Documentation for Materiality

1. Determination of Materiality Levels

• Case: The auditor determines a primary benchmark (e.g., pre-tax profit, total revenue, total assets) relevant to ABC Manufacturing Company’s financial health and operational context. A percentage is then applied to this benchmark to calculate the overall materiality for the financial statements.

• Documentation: Document the rationale for selecting the benchmark(s), the percentage applied to determine materiality, and the resulting materiality figure. This documentation provides a basis for the materiality level set and its appropriateness given the company’s circumstances.

2. Performance Materiality

• Case: To account for the possibility of undetected misstatements, the auditor sets performance materiality, typically a percentage of the overall materiality, to reduce to an appropriately low level the probability that the aggregate of uncorrected and undetected misstatements exceeds materiality.

• Documentation: Document the calculation of performance materiality and the rationale for the chosen percentage, ensuring it’s suitably conservative given the assessed risks of material misstatement.

3. Tolerable Misstatement for Specific Accounts

• Case: For significant account balances or transaction classes, the auditor may set tolerable misstatement levels lower than performance materiality to address risks specific to those accounts.

• Documentation: Provide calculations for tolerable misstatement for significant accounts or classes of transactions, including the basis for any variations from performance materiality.

4. Revision of Materiality

• Case: During the audit, if new information emerges that affects the auditor’s initial assessment of materiality (e.g., a significant post-balance sheet event), the auditor reassesses and, if necessary, revises materiality levels.

• Documentation: Document any changes to materiality levels, including the reasons for the revision and how these changes impact the audit strategy and procedures.

5. Evaluation of Misstatements

• Case: As misstatements are identified, they are aggregated, and their significance is evaluated against the predetermined materiality levels. This includes both quantifiable misstatements and qualitative considerations.

• Documentation: Summarize identified misstatements, including both corrected and uncorrected items, and their evaluation against materiality. Document discussions with management regarding the need for adjustments and the rationale for any misstatements deemed immaterial.

6. Communication with Those Charged with Governance

• Case: Materiality and the implications of identified misstatements are communicated to those charged with governance, typically including a discussion of the nature of any uncorrected misstatements and their context within the audit.

• Documentation: Prepare a summary of communications with those charged with governance regarding materiality and misstatements, highlighting how these factors influence the audit opinion.

Conclusion

Materiality is a cornerstone of the audit process, guiding the auditor’s focus and influencing the conduct of the audit from planning through to conclusion. Documenting the basis for materiality decisions, how materiality is applied in the audit, and the handling of identified misstatements is critical for transparency and the integrity of the audit process. This approach ensures that the audit provides reasonable assurance that the financial statements as a whole are free from material misstatement, whether due to fraud or error.
