There is created a fund to be known as the Georgia Public School Personnel Indemnification Fund. The custodian of the Georgia Public School Personnel Indemnification Fund shall be the Department of Administrative Services. The Department of Administrative Services shall administer the Georgia Public School Personnel Indemnification Fund and may invest the resources of the fund in the same manner and fashion that an insurer authorized to issue contracts of life insurance is authorized to invest its resources. The Department of Administrative Services shall be further authorized to intermingle the resources of the Georgia Public School Personnel Indemnification Fund with the resources of any other funds or accounts which have similar restrictions on the investments which may be made with such funds; provided, however, that separate bookkeeping accounts on each such fund shall be maintained.
