Definition: The U.S. government agency responsible for regulating and supervising the securities industry.

The Securities and Exchange Commission, commonly referred to as the SEC, enforces, among other acts, the Securities Act of 1933, the Securities Exchange Act of 1934, the Trust Indenture Act of 1939, the Investment Company Act of 1940 and the Investment Advisors Act.

The SEC has five Commissioners who are appointed by the President of the United States with the advice and consent of the Senate. Their terms last five years and are staggered so that one Commissioner's term ends on June 5 of each year. To ensure that the SEC remains non-partisan, no more than three Commissioners may belong to the same political party. The President also designates one of the Commissioners as Chairman, the SEC's top executive.
