N.M. Stat. § 53-11-30
For the purpose of determining shareholders entitled to notice of, or to vote at, any meeting of shareholders or any adjournment thereof, or entitled to receive payment of any dividend, or in order to make a determination of shareholders for any other proper purpose, the board of directors of a corporation may provide that the stock transfer books shall be closed for a stated period not to exceed fifty days. If the stock transfer books are closed for the purpose of determining shareholders entitled to notice of, or to vote at, a meeting of shareholders, the books shall be closed for at least ten days immediately preceding the meeting. In lieu of closing the stock transfer books, the bylaws, or in the absence of an applicable bylaw, the board of directors may fix in advance a date as the record date for any such determination of shareholders, the date to be not more than fifty days and, in case of a meeting of shareholders, not less than ten days prior to the date on which the particular action, requiring such determination of shareholders, is to be taken. If the stock transfer books are not closed and no record date is fixed for the determination of shareholders entitled to notice of, or to vote at, a meeting of shareholders, or shareholders entitled to receive payment of a dividend, 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, shall be the record date for the determination of shareholders. When a determination of shareholders entitled to vote at any meeting of shareholders has been made as provided in this section, the determination shall apply to any adjournment thereof.
