A member may file a detailed statement of:
The member may purchase credit for the service by paying into the annuity savings fund the amount required by applying the factor, supplied by the actuary as being applicable to the member's age at the time of the purchase, to the member's salary at that time, or to the highest annual compensation for service in this State for which contributions were made during any prior fiscal year of membership, whichever is greater. The purchase may be made in regular installments, equal to at least one-half the full normal contribution to the retirement system, over a maximum period of 10 years. Neither the State nor the employer of a member who applies to purchase credit for public employment with the United States Government pursuant to subsection b. of this section or for military service pursuant to subsection c. of this section shall be liable for any payment to the retirement system on behalf of the member for the purchase of this credit.
Notwithstanding any provision of this act to the contrary, a member shall not be liable for any costs associated with the financing of pension adjustment benefits and health care benefits for retirees when purchasing credit for school service, public employment in other states or with the United States Government, or military service in the Armed Forces of the United States.
Any member electing to purchase the service who retires prior to completing payments as agreed with the retirement system will receive pro rata credit for service purchased prior to the date of retirement, but if the member so elects at the time of retirement, the member may make the additional lump sum payment required at that time to provide full credit.
Notwithstanding any other provision of law to the contrary, service credit established in the retirement system by a member through purchase in accordance with this section, which purchase was made by an application submitted on or after the effective date of P.L. 2008, c. 89, except a purchase for military service in the Armed Forces of the United States, shall not be eligible for consideration when service is used to determine the qualification of the member for any health care benefits coverage paid, in whole or in part, by a public employer after the member's retirement.
