Nev. Rev. Stat. § 82.331

The articles or bylaws of any corporation may provide that at all elections of directors of the corporation each member having a right to elect directors at the meeting is entitled to as many votes as equal the number of his or her memberships multiplied by the number of directors to be elected, and that the member may cast all of his or her membership votes for a single director or may distribute them among the number to be voted for or any two or more of them, as the member may see fit. In order to exercise the right of cumulative voting, one or more of the members calling or requesting a vote by cumulative voting must give notice before the vote to the president or secretary of the corporation that the member desires that the voting for the election of directors be cumulative.
