California Code, Government Code - GOV § 20592

Notwithstanding any other provision of law, when all or part of an employer's function is transferred to an entity that is not an employer, the board may, by contract between the board, the employer, and the succeeding entity, transfer all or part of the assets and liabilities accumulated in this system by the employer to the succeeding entity.

Members employed by that employer shall have an individual election whether all accumulated contributions shall be transferred to the succeeding entity or left on deposit with this system.

The accumulated contributions may be directly transferred to the succeeding entity by the board for those members who so request.
