Title IV of the Sarbanes-Oxley Act of 2002 focuses on improving financial disclosures. Section 404 is the most controversial provision, as it obliges issuers to include an internal control report in their annual reports. Section 404 requires businesses to comply and evaluate their internal controls, with management assessing control effectiveness and external auditors providing an independent opinion. Companies must follow guidelines like COSO when establishing and evaluating their internal controls under Section 404.
