The Sarbanes–Oxley Act of 2002 is a United States federal law that mandates certain practices in financial record keeping and reporting for corporations. The act,, also known as the "Public Company Accounting Reform and Investor Protection Act" and "Corporate and Auditing Accountability, Responsibility, and Transparency Act" and more commonly called Sarbanes–Oxley, SOX or Sarbox, contains eleven sections that place requirements on all U.S. public company boards of directors and management and public accounting firms. A number of provisions of the Act also apply to privately held companies, such as the willful destruction of evidence to impede a federal investigation.

A public company is a company whose ownership is organized via shares of stock which are intended to be freely traded on a stock exchange or in over-the-counter markets. A public company can be listed on a stock exchange, which facilitates the trade of shares, or not. In some jurisdictions, public companies over a certain size must be listed on an exchange. In most cases, public companies are private enterprises in the private sector, and "public" emphasizes their reporting and trading on the public markets.
