Previously, the bylaws provided for the election of directors by plurality vote in all cases. Election of directors by a plurality vote will continue to apply for contested elections. The board also approved amendments to the BOKF bylaws to provide for uncertificated shares, thus permitting book-entry ownership, as required by Rule 3450(l) of the Nasdaq Stock Market, LLC. Finally, the board approved certain administrative changes to update the bylaws including expressly providing that i) voting lists shall be made available to shareholders at least ten calendar days prior to a shareholder meeting, ii) the board may form committees other than an executive committee, iii) directors may participate in meetings by electronic means, and iv) the determination of record holders and the timeframe within which to establish record dates is consistent with current Oklahoma state law.
