Okla. Stat. tit. 74, § 74-913.8: Military service credit - payment

A. Any active member of the Oklahoma Public Employees

Retirement System who served in any branch of the United States

Armed Forces or any component thereof, who was honorably discharged,

and whose initial membership in the System began on or after July 1,

2000, may receive up to five (5) years of military service credit as

otherwise provided in Section 901 et seq. of this title, only upon

payment of the actuarial cost of the service credit as determined by

the Board pursuant to Section 913.5 of this title. Any active

member of the Oklahoma Public Employees Retirement System who served

in any branch of the United States Armed Forces or any component

thereof, who was honorably discharged, and whose initial membership

in the System began prior to July 1, 2000, and whose military

service does not qualify as service which can be granted to a member

under Section 913 of this title, shall be eligible to purchase

service credit pursuant to this subsection. For purposes of this

subsection, “military service” means service in the Armed Forces of

the United States by honorably discharged persons.

B. The combined amount of service granted under subsection B of

Section 913 of this title, and service purchased pursuant to

subsection A of this section, shall not exceed five (5) years.

C. For a member of the System hired on or after July 1, 2003,

if the military service credit authorized by this section is used to

compute the retirement benefit of the member and the member retires

from the System, such military service credit shall not be used to

compute the retirement benefit in any other retirement system

created pursuant to the Oklahoma Statutes and the member may receive

credit for such service only in the retirement system from which the

member first retires.
