    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.
