What Is PCAOB?
The PCAOB, which stands for Public Company Accounting Oversight Board, is a private-sector, non-profit corporation created by the Sarbanes-Oxley Act of 2002 (SOX). Its primary mission is to oversee the audits of public companies to protect investors and further the public interest in the preparation of informative, accurate, and independent audit reports. Before SOX, the accounting profession largely regulated itself. However, a series of high-profile corporate accounting scandals in the early 2000s, such as Enron and WorldCom, shattered public confidence in financial reporting and the independence of auditors. Congress responded by establishing the PCAOB, placing auditor regulation under the oversight of an independent body rather than solely within the profession itself. The PCAOB registers accounting firms that audit public companies, establishes auditing and professional practice standards for these firms, conducts inspections to assess their compliance with these standards, and can investigate and discipline firms for violations. Essentially, the PCAOB sets the rules for how audits of publicly traded companies must be performed and then checks to see if accounting firms are playing by those rules. It acts under the general oversight of the U.S. Securities and Exchange Commission (SEC).
