The authority may create an insurance fund consisting solely of program funds which must be held as security for the holders of bonds issued under this act. Such funds shall be held in the custody of the State Treasurer, or with his approval may be held in the custody of one or more commercial banks or trust companies having a principal place of business in this State. The authority also may use program funds to purchase insurance to be pledged for the security of the holders of any bonds issued under this act.
In any case in which insurance is pledged as security, whether obtained through the insurance funds authorized to be created under this section or purchased with program funds, it must expressly state the limitation of the liability of the authority and further that neither the credit nor taxing power of the State or any political subdivision thereof is available to satisfy any obligations with respect thereto.
