Alaska Stat. § 10.15.080

For the purpose of determining shareholders entitled to notice of or to vote at meetings, or entitled to receive payment of a dividend, the bylaws may fix in advance a date as the record date for the determination of shareholders. The date shall be not more than 50 days and not less than 10 days prior to the date on which the particular action requiring the determination of shareholders is to be taken. If no record date is fixed by the bylaws, the date on which notice of the meeting is mailed or the date on which the resolution of the board of directors declaring the dividend is adopted, as the case may be, is the record date for the determination of shareholders. When a determination of shareholders entitled to vote at a meeting is made as provided in this section, the determination applies to any adjournment of that meeting.
