The PCAOB inspects registered public accounting firms to assess compliance with the Sarbanes-Oxley Act, the rules of the Board, the rules of the Securities and Exchange Commission, and professional standards, in connection with the firm's performance of audits, issuance of audit reports, and related matters involving U.S. public companies, other issuers, and broker-dealers.

Our inspections are designed to review portions of a firm’s issuer audits and evaluate elements of a firm’s system of quality control. The process aims to drive improvement in the quality of audit services through a focus on effective prevention, detection, and deterrence of audit and quality control deficiencies—and oversight of firms’ remediation of identified deficiencies.

Firm Inspection Reports

The Sarbanes-Oxley Act authorizes the PCAOB to inspect registered firms for the purpose of assessing compliance with certain laws, rules, and professional standards in connection with a firm's audit work for public company and broker-dealer clients. The PCAOB provides each firm with issuer audit clients inspected with a report, which summarizes any deficiencies identified through the inspections process. Each year, we publish a summary report that provides information on the inspections conducted of firms with broker-dealer clients.
