(2) electronic notification, if the person required to make the notification primarily communicates with the New Mexico resident by electronic means or if the notice provided is consistent with the requirements of 15 U.S.C. Section 7001 ; or

(3) a substitute notification, if the person demonstrates that:

(a) the cost of providing notification would exceed one hundred thousand dollars ($100,000);
