AS 3101: Requirements for the Auditor’s Report

The Public Company Accounting Oversight Board (PCAOB) standard AS 3101 establishes the requirements for the independent auditor’s report that accompanies a company’s audited financial statements. Its primary function is to dictate the report’s structure and content to make it more informative for investors, creditors, and other users. The standard ensures a consistent format for these reports, which helps users compare information across different companies and gives stakeholders a clearer understanding of the audit performed and the conclusions reached.

Core Components of the Auditor’s Report

The auditor’s report begins with a specific title and addressee to establish its formal nature. AS 3101 mandates the title “Report of Independent Registered Public Accounting Firm,” which communicates that the report is from an external auditor registered with the PCAOB. The report is addressed to the company’s board of directors and its shareholders, as they are the parties who engage the auditor to provide an independent opinion.

Following the title, the “Opinion on the Financial Statements” section presents the auditor’s conclusion from the audit. The auditor expresses an opinion on whether the company’s financial statements are presented fairly, in all material respects, in conformity with the applicable financial reporting framework, such as Generally Accepted Accounting Principles (GAAP). The most common outcome is an “unqualified opinion,” indicating the financial statements are free from material misstatements.

To support the conclusion in the opinion section, the report must include a section titled “Basis for Opinion.” This part states that the audit was conducted in accordance with PCAOB standards. This section also includes a declaration that the audit firm is independent of the company as required by the U.S. securities laws and the rules of the Securities and Exchange Commission (SEC) and the PCAOB.

The “Basis for Opinion” section also clarifies the distinct roles of the two main parties involved. It explains that company management is responsible for preparing the financial statements and for maintaining effective internal control over financial reporting. In contrast, it describes the auditor’s responsibility as expressing an opinion on those financial statements based on the audit performed.

Understanding Critical Audit Matters

A significant portion of the auditor’s report is dedicated to the communication of Critical Audit Matters (CAMs). A CAM is defined by the PCAOB as any matter that arises from the audit of the financial statements that was communicated to the company’s audit committee. To qualify as a CAM, the matter must also relate to accounts or disclosures that are material to the financial statements and involve especially challenging, subjective, or complex auditor judgment.

The process for determining a CAM is systematic. Auditors begin by reviewing all matters that were communicated to the audit committee. From this pool of items, the auditor identifies those that relate to material accounts or disclosures. The final step involves the application of professional judgment to determine if the matter involved especially challenging, subjective, or complex auditor judgment.

When a CAM is identified, AS 3101 prescribes specific communication requirements for the auditor’s report. For each CAM, the auditor must identify the matter clearly. The report must then describe the principal considerations that led the auditor to determine it was a CAM, providing transparency into the auditor’s thought process. The communication also details how the CAM was addressed during the audit, which may include a description of the audit procedures performed or the outcome of those procedures.

Finally, the discussion of each CAM must include a reference to the relevant financial statement accounts or disclosures. For instance, an auditor might identify the valuation of goodwill for a specific reporting unit as a CAM. The report would explain that this involved complex judgment due to the significant assumptions management used in its impairment test, such as future cash flow projections and discount rates. The auditor would then describe how they evaluated those assumptions and would reference the goodwill and intangible asset disclosures.

Concluding Report Elements

The final elements of the auditor’s report provide additional context and accountability. The report must include the signature of the public accounting firm that performed the audit. A requirement is the disclosure of auditor tenure, which states the year in which the auditor began serving consecutively as the company’s auditor. This information allows investors to see the length of the relationship between the company and its audit firm.

Alongside the signature and tenure, the report must specify the city and state of the audit firm’s office that issued the report. The date of the auditor’s report is another concluding element. This date signifies the conclusion of the auditor’s evidence-gathering procedures, often referred to as the end of fieldwork. The report date also defines the end of the period for which the auditor is responsible for reviewing subsequent events that could affect the financial statements.
