( a ) The rules of each exchange shall provide as follows: No rule, stated policy, practice, or interpretation of this exchange shall permit the listing, or the continuance of the listing, of any common stock or other equity security of a domestic issuer, if the issuer of such security issues any class of security, or takes other corporate action, with the effect of nullifying, restricting or disparately reducing the per share voting rights of holders of an outstanding class or classes of common stock of such issuer registered pursuant to section 12 of the Act.
( b ) The rules of each association shall provide as follows: No rule, stated policy, practice, or interpretation of this association shall permit the authorization for quotation and/or transaction reporting through an automated inter-dealer quotation system (“authorization”), or the continuance of authorization, of any common stock or other equity security of a domestic issuer, if the issuer of such security issues any class of security, or takes other corporate action, with the effect of nullifying, restricting, or disparately reducing the per share voting rights of holders of an outstanding class or classes of common stock of such issuer registered pursuant to section 12 of the Act.
( c ) For the purposes of paragraphs (a) and (b) of this section, the following shall be presumed to have the effect of nullifying, restricting, or disparately reducing the per share voting rights of an outstanding class or classes of common stock: ( 1 ) Corporate action to impose any restriction on the voting power of shares of the common stock of the issuer held by a beneficial or record holder based on the number of shares held by such beneficial or record holder;
( 2 ) Corporate action to impose any restriction on the voting power of shares of the common stock of the issuer held by a beneficial or record holder based on the length of time such shares have been held by such beneficial or record holder;
( 3 ) Any issuance of securities through an exchange offer by the issuer for shares of an outstanding class of the common stock of the issuer, in which the securities issued have voting rights greater than or less than the per share voting rights of any outstanding class of the common stock of the issuer.
( 4 ) Any issuance of securities pursuant to a stock dividend, or any other type of distribution of stock, in which the securities issued have voting rights greater than the per share voting rights of any outstanding class of the common stock of the issuer.
( d ) For the purpose of paragraphs (a) and (b) of this section, the following, standing alone, shall be presumed not to have the effect of nullifying, restricting, or disparately reducing the per share voting rights of holders of an outstanding class or classes of common stock: ( 1 ) The issuance of securities pursuant to an initial registered public offering;
( 2 ) The issuance of any class of securities, through a registered public offering, with voting rights not greater than the per share voting rights of any outstanding class of the common stock of the issuer;

( 4 ) Corporate action taken pursuant to state law requiring a state's domestic corporation to condition the voting rights of a beneficial or record holder of a specified threshold percentage of the corporation's voting stock on the approval of the corporation's independent shareholders.
( e ) *Definitions.* The following terms shall have the following meanings for purposes of this section, and the rules of each exchange and association shall include such definitions for the purposes of the prohibition in paragraphs (a) and (b), respectively, of this section: ( 1 ) The term *Act* shall mean the Securities Exchange Act of 1934, as amended.
( 2 ) The term *common stock* shall include any security of an issuer designated as common stock and any security of an issuer, however designated, which, by statute or by its terms, is a common stock (e.g., a security which entitles the holders thereof to vote generally on matters submitted to the issuer's security holders for a vote).
( 3 ) The term *equity security* shall include any equity security defined as such pursuant to Rule 3a11-1 under the Act (17 CFR 240.3a11-1).

( 5 ) The term *security* shall include any security defined as such pursuant to section 3(a)(10) of the Act, but shall exclude any class of security having a preference or priority over the issuer's common stock as to dividends, interest payments, redemption or payments in liquidation, if the voting rights of such securities only become effective as a result of specified events, not relating to an acquisition of the common stock of the issuer, which reasonably can be expected to jeopardize the issuer's financial ability to meet its payment obligations to the holders of that class of securities.
( 6 ) The term *exchange* shall mean a national securities exchange, registered as such with the Securities and Exchange Commission pursuant to section 6 of the Act (15 U.S.C. 78f), which makes transaction reports available pursuant to § 242.601 of this chapter; and
