(1) Any property or securities lawfully acquired by an insurer which it could not otherwise have invested in or loaned its funds upon at the time of such acquisition shall be disposed of within 3 years from the date of acquisition, unless within such period the security has attained to the standard of eligibility except that any security or property 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 office under chapter 628. 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 office may extend the disposal period for an additional reasonable time.
(2) Any property or securities lawfully acquired and held by an insurer after expiration of the period for disposal thereof or any extension of such period granted by the office shall not be allowed as an asset of the insurer.
