Pursuant to sections 10a-109f and 10a-109g, the university may enter into financing documents and issue securities for the purpose of refinancing securities, including the payment of any redemption premium on the securities or any interest accrued or to accrue to the date of redemption of those obligations, and if deemed advisable by the university for the additional purpose of construction or enabling the construction of improvements, extensions, enlargements or additions of the project or projects in connection with which the securities to be refunded have been issued. The university may also borrow and issue securities for the combined purpose of refunding any securities then outstanding or if authorized by law, refunding general obligation debt of the state, including the payment of any redemption premiums on the securities or general obligation debts of the state, and any interest accrued or to accrue to the date of redemption of those obligations, and paying all or any part of the cost of acquiring or constructing or enabling the acquisition or construction of any additional project or projects or part of a project, or any improvements, extensions, enlargements or additions of any project or projects. The incurring of indebtedness for refunding purposes and the issuance of securities in connection with the indebtedness, the maturities and other details, the rights and remedies of the holders and the rights, powers, privileges, duties and obligations of the university with respect to the indebtedness are governed by sections 10a-109a to 10a-109y, inclusive, insofar as the same may be applicable. In the event the university refunds general obligation debt of the state not previously issued to finance any project or projects, the Treasurer of the state is authorized to discharge the university from an amount of its obligations to reimburse the state for debt service on general obligation debt of the state issued to finance any project or projects that is equivalent to the general obligation debt of the state actually being refunded by the issuance of bonds under sections 10a-109a to 10a-109y, inclusive. Equivalent amounts must be determined on the basis of the discounted present value of all such obligations. Any refunding of securities secured by the state debt service commitment shall be conditioned upon a certification of the Treasurer that the refunding is reasonably expected as of the date of the certification to achieve, as a result of the sale of such refunding securities and the investment and application of the proceeds of such sale, net debt service savings.
