Mo. Rev. Stat. § 173.405
The principal of and interest on any bonds issued by the authority shall be secured by a pledge of the revenues derived from or by reason of the ownership of student loan notes and investment income or such other funds as may be designated in a bond resolution authorized by the authority. The bond resolution under which the bonds are authorized to be issued may contain any agreements and provisions respecting the purchase and sale of student loan notes or financing of student loans, or both, the creation and maintenance of special funds from such revenues or receipts, and the rights and remedies available in the event of default, including the designation of a trustee, all as the authority shall deem advisable and not in conflict with the provisions hereof. The principal of and interest on any other form of indebtedness issued by the authority shall be secured in such manner as may be set forth in the bond resolution authorizing such indebtedness and such bond resolutions may contain such other agreements and provisions as the authority may determine. Each pledge, agreement, and indenture made for the benefit or security of any of the bonds or other forms of indebtedness of the authority shall continue effective until the principal of and interest thereon for the benefit of which the same were made shall have been fully paid or provisions for such payment duly made. In the event of a default in the payment or in any agreement of the authority made as a part of the bond resolution under which the bonds or other forms of indebtedness were issued or secured, the payment or agreement may be enforced by suit, mandamus, the appointment of a receiver in equity, or any one or more of these remedies.
