Ed. Code, § 22806

(a) A member who retired on or after December 31, 1981, may elect to receive credit under this part, of not to exceed four years, for time served of not less than one year, prior to membership in the Defined Benefit Program, in the Armed Forces of the United States or in the Merchant Marine of the United States. Service credit shall not be granted if that service terminated with a discharge under dishonorable conditions. The service credit to be accorded pursuant to this section for that service shall be on the basis of one year of credit for each five years of credited service, but shall not exceed a total of four years of service credit regardless of the number of years of either that service or subsequent service. A member electing to receive credit under this part for that service shall have been credited with at least 10 years of service on the date of election.

(b) A member who elects to become subject to this section shall pay all reasonable administrative costs and contributions, sufficient to cover the total employer and employee cost plus interest of the military service credit, to be calculated in a manner consistent with other permissive service credit purchases in this chapter, as determined by the board.

(c) This section shall not apply to a member who is receiving either of the following:

(1) Military retirement pay based on 20 or more years of active duty with the Armed Forces of the United States, except for credit toward military retirement pay that is earned by a combination of active duty and nonactive duty with a reserve component of the Armed Forces of the United States and where the retirement pay is payable only upon the attainment of a specified age.

(2) Disability retirement pay that is paid by one of the Armed Forces of the United States, except for a member who is receiving disability compensation from the Veterans Administration and is not receiving retirement pay from one of the Armed Forces of the United States.

(d) A member shall not receive credit for service or time under this section if the member has received or is eligible to receive credit for the same service or time in the Cash Balance Benefit Program under Part 14 (commencing with Section 26000) or in another public retirement system.

(e) The board has no duty to locate or notify any member or to provide the name or address of any member, agency, or entity for the purpose of notifying those persons.
