## Understanding the Public Company Accounting Oversight Board

The Public Company Accounting Oversight Board (PCAOB) was established with the passage of the [Sarbanes-Oxley Act of 2002](https://www.investopedia.com/terms/s/sarbanesoxleyact.asp). The act was passed in response to various accounting scandals of the late 1990s. The board protects investors and other stakeholders of public companies by ensuring that the auditor of a company's financial statements has followed a set of strict guidelines.

The PCAOB is overseen by the [Securities and Exchange Commission](https://www.investopedia.com/terms/s/sec.asp) and, since 2010, the PCAOB has overseen the audits of SEC-registered brokers and dealers.

## PCAOB Advisory Groups

The PCAOB has two advisory groups: the Standing Advisory Group and the Investor Advisory Group. The role of these two groups is to provide advice and insight to the Board.

The Standing Advisory Group meets semi-annually to discuss data and technology, cybersecurity, corporate culture, communications on PCAOB standards, the governance and leadership of quality control systems, current or emerging issues affecting audits or auditors, and implementation of the new auditor’s report.

The Investor Advisory Group meets once a year to discuss the group's strategic plan, quality control standards, implementation of the new auditor’s report, and implementation of Form AP. The PCAOB Board has developed a five-step strategic plan, which is laid out in its annual report. The five-step plan is composed of the following:

*   Drive improvement in the quality of audit services through a combination of prevention, detection, deterrence, and remediation.
*   Anticipate and respond to the changing environment, including emerging technologies and related risks and opportunities.
*   Enhance transparency and accessibility through proactive stakeholder engagement.
*   Pursue operational excellence through efficient and effective use of our resources, information, and technology.
*   Develop, empower, and reward our people to achieve our shared goals.
