How Does the PCAOB Standard Setting Process Work?

The Public Company Accounting Oversight Board (PCAOB) is central to the reliability of financial reporting for public companies in the United States. Congress established the PCAOB through the Sarbanes-Oxley Act of 2002, enacted in response to major corporate and accounting scandals. The board’s primary mission is to oversee the audits of public companies to protect the interests of investors and further the public interest in the preparation of informative, accurate, and independent audit reports.

A core function of the PCAOB is to establish and maintain the professional standards that registered public accounting firms must follow when auditing public companies. The process for creating and updating these standards is deliberate, transparent, and designed to incorporate a wide range of perspectives to ensure the final rules are robust and effective. This structured approach helps maintain high-quality audits and builds investor confidence.

Identifying the Need for a New Standard

The standard-setting process begins with the identification of an issue in the audit environment that may require a new rule or an amendment to an existing one. The PCAOB’s own oversight activities are a primary source of these ideas. Findings from inspections of registered audit firms can reveal recurring deficiencies in how audits are performed, highlighting areas where existing standards may be insufficient or unclear.

The PCAOB’s Office of the Chief Auditor, along with other divisions, actively monitors the financial landscape for developments that could impact auditing. This includes tracking new and complex financial transactions, the adoption of emerging technologies like data analytics and artificial intelligence, and broader economic trends. This research is informed by discussions with staff at the Securities and Exchange Commission and the work of international standard-setters.

Another source of ideas is direct outreach with a broad array of stakeholders, including investors, the audit committees of public company boards, financial statement preparers, and auditors. If the analysis suggests a potential need for regulatory action, the issue may be added to the Board’s public research agenda, which outlines topics under active consideration.

Should further research confirm the need for a new or amended standard, the project is moved to the official standard-setting agenda. This agenda is a public document, providing transparency about the issues the PCAOB intends to address.

The Public Rulemaking and Proposal Stage

Once a project is placed on the standard-setting agenda, the PCAOB begins the formal process of developing a new or amended standard. Staff from the Office of the Chief Auditor, in collaboration with other offices like the Office of Economic and Risk Analysis, work to draft the text of the proposed standard. This process includes a detailed analysis of the issue, consideration of alternative approaches, and an evaluation of the potential economic impacts, including the costs and benefits of the proposed changes.

When the drafting is complete, the Board holds a public meeting to consider the proposal. If the Board votes to issue it, the PCAOB releases a comprehensive document for public comment. This proposal release contains the full text of the proposed standard, a detailed explanation of its purpose, the Board’s rationale, and specific questions for public feedback.

The release of the proposal initiates a formal public comment period, which usually lasts for 60 to 90 days. During this time, any interested party—including investors, accounting firms, public companies, and academics—can submit a written comment letter. All comment letters are made publicly available on the PCAOB’s website.

For particularly significant proposals, the PCAOB may hold public meetings or roundtables. Participants, who are invited by the Board and represent a variety of stakeholder groups, can discuss the proposal’s practical implications and debate its more challenging aspects directly with Board members and staff.

Finalizing and Adopting the Standard

After the public comment period closes, the process moves into an internal analysis and revision phase. PCAOB staff undertake a review of all the feedback received from comment letters and public meetings. This analysis of public input directly informs the next iteration of the standard. The staff evaluates the arguments presented by commenters and determines whether and how to revise the proposal.

This can lead to significant changes, such as clarifying language, modifying specific requirements to make them more practical, or adding or removing provisions to better achieve the standard’s objectives. The staff prepares a detailed analysis summarizing the feedback and explaining how it was addressed in the recommended final standard.

Once the staff has finalized its recommendation, the matter is brought before the Board for a second time at a public meeting. The staff presents an overview of the rule, a summary of the public comments received, and the rationale for the changes made since the proposal stage. Following this discussion, the Board members vote on whether to adopt the standard.

If the vote is successful, the PCAOB issues an “adopting release.” This document contains the final, official text of the new standard, a detailed discussion of the public comments and the Board’s responses, and the effective date for compliance.

Securities and Exchange Commission Approval

The PCAOB’s process does not end with its own Board’s vote. Under the Sarbanes-Oxley Act, all final rules and standards adopted by the PCAOB must be submitted to the Securities and Exchange Commission (SEC) for approval before they can take effect. Upon receiving the adopted standard from the PCAOB, the SEC initiates its own review process.

The SEC publishes the PCAOB’s rule in the Federal Register, which opens another public comment period, allowing stakeholders to provide their views directly to the SEC. The SEC’s review is guided by a mandate to determine if the PCAOB’s standard is necessary or appropriate in the public interest or for the protection of investors.

After its comment period closes and its staff completes its review, the SEC takes formal action. There are three potential outcomes:

• Issue an order approving the standard, which gives it legal effect.
• Disapprove the rule if it finds it does not meet the statutory criteria.
• Institute proceedings to determine whether the rule should be disapproved, which may involve remanding it back to the PCAOB for further consideration.

Post-Implementation Review

The lifecycle of a standard extends beyond its final approval and effective date. After a new or significantly revised standard has been in effect for a period of time, usually a few years, the PCAOB may conduct a Post-Implementation Review (PIR). The purpose of a PIR is to evaluate whether the standard is accomplishing its intended objectives in practice.

The review seeks to assess both the benefits and the costs associated with the standard. The PCAOB’s staff gathers and analyzes data to understand the standard’s impact on audit quality, its effect on the behavior of auditors and companies, and any unintended consequences. The process often involves outreach to the same stakeholder groups that participated in the initial rulemaking to gather their real-world experiences with the standard.

The findings from the Post-Implementation Review are compiled into a public report. This report details the analysis and conclusions about the standard’s overall effectiveness. The insights gained from a PIR inform future regulatory action. For example, the review might conclude that the standard is working as intended, that minor amendments are needed, or that new guidance would be helpful to improve its application.
