SOX or Sarbanes-Oxley Act is a law that sets principles of conduct and regulations for public accounting firms and public company boards. The law was passed to improve the confidence of the investors so they can continue to invest in the United States security markets. The law also allows the creation of a public agency known as PCAOB.
This agency was created to regulate, oversee, and to audit public companies. The agency is also empowered to discipline officials of any public company that are involved in any financial irregularities. However, SOX is only applicable to public companies in the United States. On the other hand, operational audit makes use of accountants from reliable accounting firms to carry out audits of corporations and companies to check their financial systems.
The operational audit also helps check a company’s financial effectiveness and efficiency. Unlike the operational audit, SOX is compulsory for all public companies. Operational audit is for all companies, whereas SOX is carried out for public companies alone.
