controlling interest

A controlling interest is when a shareholder or group of shareholders in a corporation own enough voting stock to govern the outcome of important business decisions. A voting stock is a portion of ownership in a company that grants voting rights on shareholder motions, as set out in the company's charter. Not all stocks give voting rights, so a majority of the total stock might not be a controlling interest. However, common stock does typically provide voting rights.

See: 15 U.S. Code § 9054
