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 companies, other issuers, and broker-dealer clients.
Registered firms that issue 100 or fewer audit reports for issuers are, in general, inspected at least once every three years. Registered firms that issue audit reports for more than 100 issuers are inspected annually. The Board also inspects registered firms that play a substantial role in audits of issuers. Many firms registered with the Board perform no audit work for issuers, and the Board does not inspect those firms.
While the information contained here focuses on our inspections of issuer audits, more information on broker-dealer inspections can be found on our dedicated page.
