What is one of the major requirements for auditors under the Sarbanes-Oxley Act?

One of the major requirements for auditors under the Sarbanes-Oxley Act is that they must rotate every two years. This requirement aims to enhance the independence and objectivity of auditors, reducing the risk of complacency or favoritism that can arise from long-term relationships between auditors and the companies they audit. By mandating the rotation of audit firms after a certain period, the act seeks to ensure that fresh perspectives are brought into the auditing process, which can contribute to more accurate and independent financial reporting.

The other options, while they may have relevance in different contexts, do not align with the requirements set forth by the Sarbanes-Oxley Act. Non-audit services are actually restricted under the act to maintain auditor independence. Reducing costs is not a requirement established by the legislation; rather, the focus is on the integrity and reliability of financial reporting. Lastly, while audit fees are important, the act does not specifically require disclosure of fees before engagement, unlike the emphasis placed on auditor rotation.
