1. The board may authorize a tax credit, as described in this section, to the owner of any revenue bonds or notes issued by the board pursuant to the provisions of sections 100.250 to 100.297, for infrastructure facilities as defined in subdivision (9) of section 100.255, if, prior to the issuance of such bonds or notes, the board determines that:

(1) The availability of such tax credit is a material inducement to the undertaking of the project in the state of Missouri and to the sale of the bonds or notes;

(2) The loan with respect to the project is adequately secured by a first deed of trust or mortgage or comparable lien, or other security satisfactory to the board.

2. Upon making the determinations specified in subsection 1 of this section, the board may declare that each owner of an issue of revenue bonds or notes shall be entitled, in lieu of any other deduction with respect to such bonds or notes, to a tax credit against any tax otherwise due by such owner pursuant to the provisions of chapter 143, excluding withholding tax imposed by sections 143.191 to 143.261, chapter 147, or chapter 148, in the amount of one hundred percent of the unpaid principal of and unpaid interest on such bonds or notes held by such owner in the taxable year of such owner following the calendar year of the default of the loan by the borrower with respect to the project. The occurrence of a default shall be governed by documents authorizing the issuance of the bonds. The tax credit allowed pursuant to this section shall be available to the original owners of the bonds or notes or any subsequent owner or owners thereof. Once an owner is entitled to a claim, any such tax credits shall be transferable as provided in subsection 7 of section 100.286. Notwithstanding any provision of Missouri law to the contrary, any portion of the tax credit to which any owner of a revenue bond or note is entitled pursuant to this section which exceeds the total income tax liability of such owner of a revenue bond or note shall be carried forward and allowed as a credit against any future taxes imposed on such owner within the next ten years pursuant to the provisions of chapter 143, excluding withholding tax imposed by sections 143.191 to 143.261, chapter 147, or chapter 148. The eligibility of the owner of any revenue bond or note issued pursuant to the provisions of sections 100.250 to 100.297 for the tax credit provided by this section shall be expressly stated on the face of each such bond or note. The tax credit allowed pursuant to this section shall also be available to any financial institution or guarantor which executes any credit facility as security for bonds issued pursuant to this section to the same extent as if such financial institution or guarantor was an owner of the bonds or notes, provided however, in such case the tax credits provided by this section shall be available immediately following any default of the loan by the borrower with respect to the project. In addition to reimbursing the financial institution or guarantor for claims relating to unpaid principal and interest, such claim may include payment of any unpaid fees imposed by such financial institution or guarantor for use of the credit facility.

3. The aggregate principal amount of revenue bonds or notes outstanding at any time with respect to which the tax credit provided in this section shall be available shall not exceed fifty million dollars.
