(1) The State of Oklahoma, any county, city or town, or any

instrumentality thereof whose employees or a class of whose

employees are members of any other retirement or pension plan

authorized by a statute of the State of Oklahoma may, by resolution

adopted by the official board, body, or officer or officers

authorized to apply for application, request the board to submit a

proposal for consolidation of such other system with the Oklahoma

contribution rate necessary to comply with the actuarial standard of

this system. Such proposal shall provide that: (a) the operation

Public Employees Retirement System shall be offset against the

liability on account of existing retirants, annuitants, and active

members; (e) the resulting liability so determined shall be the

basis for a rate of contribution of such employer; (f) such

consolidation shall take effect only on the anniversary of the entry
