Final answer:
The incorrect statement about the Sarbanes-Oxley Act is that Oa public corporation must change its lead auditing firm every seven to ten years; this is not a requirement of the act. Instead, the act focuses on maintaining auditor independence, retaining financial documents, and establishing the PCAOB for audit oversight.
Step-by-step explanation:
In response to the student's inquiry regarding the Sarbanes-Oxley Act and its key components, it's important to clarify that one of the listed options is not an actual requirement of the act. The assertion that a public corporation must change its lead auditing firm every seven to ten years is incorrect. This specific rotation requirement does not exist within the Sarbanes-Oxley Act. The act did bring about significant changes, including:
- Prohibiting accounting firms from providing many types of non-audit and consulting services to the companies they audit in order to maintain auditor independence.
- Requiring auditors or accountants to maintain financial documents and audit work papers for a period of time, generally five to seven years.
- Mandating the establishment of the Public Company Accounting Oversight Board (PCAOB) by the Securities and Exchange Commission (SEC) to oversee the audits of public companies.
The Sarbanes-Oxley Act was enacted as a reaction to major corporate and accounting scandals to enhance corporate governance and increase the reliability of financial reporting for public corporations.
