New York Consolidated Laws, Business Corporation Law - BSC § 501. Authorized shares

(a) Every corporation shall have power to create and issue the number of shares stated in its certificate of incorporation. Such shares may be all of one class or may be divided into two or more classes. Each class shall consist of either shares with par value or shares without par value, having such designation and such relative voting, dividend, liquidation and other rights, preferences and limitations, consistent with this chapter, as shall be stated in the certificate of incorporation. The certificate of incorporation may deny, limit or otherwise define the voting rights and may limit or otherwise define the dividend or liquidation rights of shares of any class, but no such denial, limitation or definition of voting rights shall be effective unless at the time one or more classes of outstanding shares or bonds, singly or in the aggregate, are entitled to full voting rights, and no such limitation or definition of dividend or liquidation rights shall be effective unless at the time one or more classes of outstanding shares, singly or in the aggregate, are entitled to unlimited dividend and liquidation rights.

(b) If the shares are divided into two or more classes, the shares of each class shall be designated to distinguish them from the shares of all other classes. Shares which are entitled to preference in the distribution of dividends or assets shall not be designated as common shares. Shares which are not entitled to preference in the distribution of dividends or assets shall be common shares, even if identified by a class or other designation, and shall not be designated as preferred shares.

(c) Subject to the designations, relative rights, preferences and limitations applicable to separate series and except as otherwise permitted by subparagraph two of paragraph (a) of section five hundred five of this article, each share shall be equal to every other share of the same class. With respect to corporations owning or leasing residential premises and operating the same on a cooperative basis, however, provided that (1) liquidation or other distribution rights are substantially equal per share, (2) changes in maintenance charges and general assessments pursuant to a proprietary lease have been and are hereafter fixed and determined on an equal per-share basis or on an equal per-room basis or as an equal percentage of the maintenance charges, and (3) voting rights are substantially equal per share or the certificate of incorporation provides that the shareholders holding the shares allocated to each apartment or dwelling unit owned by the corporation shall be entitled to one vote in the aggregate regardless of the number of shares allocated to the apartment or dwelling unit or the number of shareholders holding such shares, shares of the same class shall not be considered unequal because of variations in fees or charges payable to the corporation upon sale or transfer of shares and appurtenant proprietary leases that are provided for in proprietary leases, occupancy agreements or offering plans or properly approved amendments to the foregoing instruments.
