N.M. Stat. § 59A-9-24
Any personal property or securities lawfully acquired by an insurer which it could not otherwise have invested in or loaned its funds upon at time of acquisition shall be disposed of by the insurer within three (3) years from date of acquisition unless within such period the property or security has attained to the status of eligibility; but any personal property or security acquired under any agreement of bulk reinsurance, merger or consolidation may be retained for a longer period if so provided in the plan for such reinsurance, merger or consolidation as approved by the superintendent under Article 34 [Chapter 59A, Article 34 NMSA 1978] of the Insurance Code. Upon application by the insurer and proof that forced sale of any such property or security would materially injure the interests of the insurer, the superintendent may extend the disposal period for an additional reasonable time.
