Prior to, and for a period of five years following, the effective date of the plan of conversion, no person or group of persons acting in concert shall directly or indirectly offer to acquire or acquire in any manner the beneficial ownership of 5 percent or more of any class of voting securities of a converted insurer or of a person that controls, as defined by subdivision (b) of Section 1215, the converted insurer, without the prior consent of the commissioner. Any application for that approval shall contain information as the commissioner may require and shall be accompanied by a filing fee in an amount equal to the filing fee specified in Section 1215.2. In the event of any violation of this section, or of any action that, if consummated, would constitute a violation, all voting securities of the converted insurer or of the person acquired by any person in excess of the maximum amount permitted to be acquired by the person pursuant to this subdivision shall be deemed to be nonvoting securities of the converted insurer or of that person. The violation or action may be enforced or enjoined by an appropriate proceeding commenced by the converted insurer, a person, the commissioner, any policyholder or stockholder of the converted insurer, or the person on behalf of the converted insurer or the person in the superior court in the judicial district in which the converted insurer has its home office or in any other court having jurisdiction. The court may issue any order it finds necessary to cure the violation or to prevent the proposed action. In addition to the foregoing, whenever it appears to the commissioner that any person has committed a violation of this section, the commissioner may proceed as provided in Article 14 (commencing with Section 1010) of Chapter 1 of Part 2 of Division 1 to take possession of the property of the converted insurer and to conduct the business thereof. For the purposes of this section, “beneficial ownership,” with respect to voting securities, means the sole or shared power to vote, or direct the voting of, voting securities or the sole or shared power to dispose, or direct the disposition, of voting securities. “Voting security” includes voting stock as defined in Section 4097.01, any preorganization certificate or subscription, including subscription rights issued pursuant to a plan of conversion, or any security convertible, with or without consideration, into voting security, or carrying any warrant or right to subscribe for or purchase any voting security, or any such warrant or right. “Offer” includes an offer to buy or acquire, solicitation of an offer to sell, tender offer for, or request or invitation for tenders of a security or interest in a security for value.
