(40 ILCS 5/16-197)
(from Ch. 108 1/2, par. 16-197)
All assets of the system shall be invested as one fund and no person,
group of persons or entity shall have any right other than to an undivided
interest in the whole, and all references to the reserves shall be
construed as not requiring a segregation of assets but only the maintenance
of a separate account indicating the equities in the assets as a whole.
