Public Accounting Firms: Required Study on the Potential Effects of Mandatory Audit Firm Rotation

Following major failures in corporate financial reporting, the Sarbanes-Oxley Act of 2002 was enacted to protect investors through requirements intended to improve the accuracy and reliability of corporate disclosures and to restore investor confidence. The act included reforms intended to strengthen auditor independence and to improve audit quality. Mandatory audit firm rotation (setting a limit on the period of years a public accounting firm may audit a particular company's financial statements) was considered as a reform to enhance auditor independence and audit quality during the congressional hearings that preceded the act, but it was not included in the act. The Congress decided that mandatory audit firm rotation needed further study and required GAO to study the potential effects of requiring rotation of the public accounting firms that audit public companies registered with the Securities and Exchange Commission.
