Nebraska Revised Statute 21-259
(MBCA 7.07) (a) The bylaws may fix or provide the manner of fixing the record date or dates for one or more voting groups in order to determine the shareholders entitled to notice of a shareholders' meeting, to demand a special meeting, to vote, or to take any other action. If the bylaws do not fix or provide for fixing a record date, the board of directors of the corporation may fix a future date as the record date.
(b) A record date fixed under this section may not be more than seventy days before the meeting or action requiring a determination of shareholders.
(c) A determination of shareholders entitled to notice of or to vote at a shareholders' meeting is effective for any adjournment of the meeting unless the board of directors fixes a new record date or dates which it must do if the meeting is adjourned to a date more than one hundred twenty days after the date fixed for the original meeting.
(d) If a court orders a meeting adjourned to a date more than one hundred twenty days after the date fixed for the original meeting, it may provide that the original record date or dates continue in effect or it may fix a new record date or dates.
(e) The record date for a shareholders' meeting fixed by or in the manner provided in the bylaws or by the board of directors shall be the record date for determining shareholders entitled both to notice of and to vote at the shareholders' meeting, unless in the case of a record date fixed by the board of directors and to the extent not prohibited by the bylaws, the board, at the time it fixes the record date for shareholders entitled to notice of the meeting, fixes a later record date on or before the date of the meeting to determine the shareholders entitled to vote at the meeting.
