WARSAW, Ind., Sept. 18 /PRNewswire-FirstCall/ -- Zimmer Holdings, Inc. (NYSE: ZMH - News; SWX: ZMH - News) announced today that its Board of Directors has amended the company's By-Laws to adopt a majority vote standard for the election of directors in uncontested elections. Previously, directors were elected under a plurality vote standard, meaning the candidates receiving the most votes would win without regard to whether those votes constituted a majority of the shares voting at the meeting. Contested elections (where there are more nominees than directors to be elected) will continue to use the plurality vote standard.
