(1) Eligibility to participate in an alternate retirement plan for an employee who is employed on or after July 1, 1997, or the effective date of the establishment of an alternate retirement plan, whichever is later, and who is represented by an exclusive bargaining representative shall be determined by the provisions of a memorandum of understanding executed between the public agency and the exclusive bargaining representative of the employee. That memorandum of understanding shall prescribe all of the terms and conditions under which the alternate plan is established including the employer and employee contribution rates.

(2) Eligibility to participate in an alternate retirement plan for an employee who is employed on or after July 1, 1997, or the effective date of the establishment of an alternate retirement plan, whichever is later, and who is not represented by an exclusive bargaining representative shall be determined by the public agency.

(3) Eligibility to participate in an alternate retirement plan established prior to July 1, 1997, for an employee who is employed prior to that date, or for plans established on or after July 1, 1997, for an employee who is employed prior to the date the plan is established, shall be determined by the employee in accordance with the following election procedures:

(A) The employer shall make available to each employee prior to October 1, 1997, or at least 90 days prior to the proposed effective date of the alternate retirement plan, whichever is later, information describing the employee’s rights and responsibilities as a participant in either this system or the alternate retirement plan offered by the employer and describing the benefits provided by this system and that alternate retirement plan. The information shall include all of the terms and conditions under which the system and the alternate retirement plan are established including the employer and employee contribution rates.

(B) An employee who fails to make an election prior to January 1, 1998, or 90 days after being given the election opportunity, whichever is later, shall be informed by the employer by certified mail that the failure to make that election has been deemed an election to participate in the alternate retirement plan whenever his or her employment fall below the requirements prescribed by Section 20305.

(C) The employer shall maintain in its files a written acknowledgment by the employee that the employee received the information required under this section within the specified timeframe and shall maintain election results and election forms of employees.

(D) The employer shall notify the system as to the results of election by employees in the manner prescribed by the board.

(b) An employee’s participation in the alternate retirement plan shall commence as soon as it is reasonable for this system to determine the member’s qualifications pursuant to Section 20305. Employers shall submit all information deemed necessary for this system to make those determinations. Participation in the alternate retirement plan shall continue until the system determines that the employee’s employment meets the conditions for membership in this system, whereupon the employee shall reenter membership in this system.

(c) Each county superintendent of schools may make the school districts in the county responsible for any administrative acts which may be necessary to implement this section. Any cost incurred by a county superintendent of schools in complying with this section shall be reimbursed on a proportional basis by those school districts in the county participating in an alternative retirement system.
