Cal. FIN § 15201

(a) The merger shall be made pursuant to any plan agreed upon by the majority of the board of directors of each credit union joining in the merger, and approved by the affirmative vote of at least a majority of the members of the disappearing credit union, in person or by proxy, at a meeting of the members called for that purpose or by written consent of a majority of the members of the disappearing credit union. Notice of the meeting shall be given to the members, either personally or by first-class mail, not less than 30 nor more than 90 days prior to the date of the meeting.

(b) The commissioner may approve a merger according to the plan agreed upon by the majority of the board of directors of each credit union, as set forth in subdivision (a), if the plan of merger is approved by less than a majority of the membership as provided in subdivision (a) if the commissioner finds, upon the written and verified application filed by the board of directors, that (1) notice of the meeting called to consider the merger or the ballot for written vote on the merger was mailed to each member entitled to vote upon the question, (2) the notice or ballot disclosed the purpose of the meeting or the written vote, (3) the notice or ballot informed the membership that approval of the merger might be sought pursuant to this section, and (4) a majority of the votes cast upon the question were in favor of the merger.

(c) Notwithstanding subdivisions (a) and (b), the commissioner may approve a merger without a vote of the membership of the disappearing credit union if a majority of the members of the board of directors of the surviving credit union approves the merger, the disappearing credit union is in danger of insolvency and the merger would reduce the risk or avoid a threatened loss to the National Credit Union Share Insurance Fund or other form of share guaranty or insurance that is acceptable to the commissioner. For purposes of this chapter, a credit union is insolvent when, from the most recent available financial statements, it can be shown that the total amount of its shares exceeds the present cash value of its assets after providing for liabilities unless the commissioner finds all of the following:

(1) The facts that caused the deficient share-asset ratio no longer exist.

(2) Further decline in the share-asset ratio is not probable.

(3) The return of the share-asset ratio to its normal limits within a reasonable time for the credit union concerned is probable.

(4) The probability of a further potential loss is negligible to the National Credit Union Share Insurance Fund or other form of share guaranty or insurance that is acceptable to the commissioner.
