SEC Form 10-12G is a filing with the Securities and Exchange Commission (SEC), also known as the General Form for Registration of Securities. This form is required when a corporation wishes to register a class of securities according to Section 12(b) or (g) of the Securities Exchange Act of 1934.1? Filing a Form 10-12G paves the way for the securities to potentially trade on U.S. exchanges. A company must file Form 10-12G if it has over $10 million in total assets and 750 or more shareholders on record.
