The Public Company Accounting Oversight Board (PCAOB) is a congressionally created nonprofit that regulates audits in US capital markets. From Washington, it oversees auditors of public companies and SEC-registered brokers and dealers using registration, standards, inspections, and enforcement.
The organization's 2025 budget funds 945 positions and is supported mainly by an accounting support fee paid by issuers and broker-dealers.
The PCAOB grew out of a crisis of trust in US markets. In the early 2000s, massive accounting scandals at Enron, WorldCom, and Arthur Andersen exposed deep problems with self-policing auditors.
Because those failures erased billions in shareholder value and retirement savings, Congress moved quickly in 2002. Through the Sarbanes-Oxley Act, Congress created the Public Company Accounting Oversight Board as an independent audit regulator.
The PCAOB operates under the Securities and Exchange Commission's (SEC) authority and focuses on protecting investors.
The new Board replaced a decades-old model where large accounting firms set and enforced their own rules. Lawmakers gave the PCAOB specific tools instead, including:
Since then, the audit regulator has been using those tools to review hundreds of firms and thousands of engagements each year. This shift helped move audit oversight from a voluntary system to one backed by federal law and public reporting.
The audit regulator first focused on standing up its core programs, often without prior regulatory blueprints to follow. It created inspection teams, an enforcement division, and a standard-setting office, then began issuing inspection reports on individual firms.
Because US-listed companies operate globally, the Public Company Accounting Oversight Board later negotiated agreements so inspectors could review audit work in dozens of non-US jurisdictions. Over time, it also added tools like AuditorSearch and inspection data sets to give investors and audit committees more granular information.
In recent years, the Public Company Accounting Oversight Board has emphasized faster inspection reporting, updated standards, and more assertive enforcement in serious cases. For example, by 2024 its staff inspected more than 230 firms and reviewed over 900 engagements worldwide.
The Board has also funded a growing scholars program with civil penalties, awarding 676 students $15,000 each for the 2024–25 year. Taken together, these steps describe how the audit regulator is changing its oversight as new risks emerge.
The PCAOB offers audit oversight tools and data that help investors assess audit quality and risk:
Overall, the Public Company Accounting Oversight Board's tools give investors, advisors, and wealth firms more concrete information about audit quality and firm behavior. Its public standards, enforcement records, and education efforts also help professionals judge the strength of financial reporting behind listed securities.
The Public Company Accounting Oversight Board says that its culture is guided by values that shape how staff approach audit oversight and internal operations:
The PCAOB also says its people are central to its mission and notes that personnel costs make up most of its operating budget. It lists specific benefits for employees:
This focus on employee support sits alongside how the Public Company Accounting Oversight Board uses some enforcement-related funds to support future auditors through education programs. Its PCAOB Scholars Program is its merit-based education and talent pipeline initiative, funded by civil monetary penalties.
Demetrios Logothetis is chair of the Public Company Accounting Oversight Board, appointed by the SEC in 2026. He previously sat on the board of The Republic Bank of Chicago and spent 40 years at Ernst and Young. Logothetis earned his MBA from the University of Chicago Booth School of Business and his BS in accountancy from DePaul University.
Logothetis leads a broader team across the board and key divisions that includes:
This structure puts board members alongside senior staff who run standards, inspections, and technology functions day to day.
Along with the SEC, the Public Company Accounting Oversight Board saw enforcement activity slow in 2025 during a midyear leadership change. It finalized 37 cases, down from 51 in 2024, and cut monetary penalties on auditing actions by about half.
Most of those penalties were decided before former chair Erica Williams left in July, so the new chair has inherited a quieter docket. Cornerstone Research, an economics and litigation consulting firm, notes that accounting firms made up more than two thirds of respondents in those cases.
For investors and advisors, this lull raises questions about how the next phase of PCAOB enforcement will look and how tough future sanctions may be.
