The Sarbanes-Oxley Act of 2002 required GAO to study the potential effects of requiring public companies registered with the Securities and Exchange Commission (SEC) to periodically rotate the public accounting firms that audit their financial statements. On November 21, 2003, GAO issued its report entitled Public Accounting Firms: Required Study on the Potential Effects of Mandatory Audit Firm Rotation (GAO-04-216). This supplemental report contains a copy of each questionnaire used in our study, annotated to show summary responses for each question and selected comments from respondents. GAO is issuing this supplemental report to provide additional detail on the responses to our surveys on the potential effects of mandatory audit firm rotation and to facilitate future research efforts in performing studies related to these matters.
