California Code, Insurance Code - INS § 1551

By following the procedure specified in this article, any domestic reciprocal insurer described in this article may merge, consolidate, or otherwise unite with or become a part of, or may reinsure all of its policies with, and, upon assumption of all of its liabilities, may transfer all of its assets to, any other domestic reciprocal insurer or an incorporated insurer, domestic or foreign.  If an insurer not admitted in California is the surviving entity in the transaction, the plan and agreement shall provide either for that insurer to be admitted to transact insurance in California or for any nonsurviving insurer admitted in California to withdraw from the state.  The plan and agreement by which the transaction is to be effected shall be approved by a resolution of a majority of the body exercising the subscribers' rights selected pursuant to Section 1308 for each domestic reciprocal insurer that is a party to the transaction or by such higher number as may be required by the documents governing the reciprocal, before it is submitted to the subscribers for their consideration.  The resolution shall specify the reasons for and the purposes of the proposed transaction and the manner in which the transaction is expected to benefit and serve the best interests of the domestic reciprocal insurer and its subscribers.  The plan and agreement shall be approved on behalf of each constituent other party by those persons required to approve those transactions by the laws under which that other party is organized or is otherwise governed.
