Montana Title 17. State Finance § 17-5-709. Continued tax deposit limit on additional bonds

(1) The legislature shall provide for the continued assessment, levy, collection, and deposit into the coal severance tax bond fund of the coal severance tax that, together with other revenue, assets, and money that may be deposited to one or more special bond funds pledged for the benefit of coal severance tax bonds, will be sufficient to produce an amount that is at least the amount necessary to pay, when due, the annual debt service charges on all outstanding coal severance tax bonds.

(2) The board of examiners may issue no coal severance tax bonds unless the aggregate amount of coal severance tax bonds outstanding, including the proposed issue and any other coal severance tax bonds authorized but not yet issued, can be serviced with no more than two-thirds of the annual deposits into the coal severance tax bond fund, as determined by the average of the deposits during the preceding 3 fiscal years, together with the average of the aggregate amount of revenue, assets, or money deposited in one or more special bond funds used to pay debt service on outstanding coal severance tax bonds during the preceding 3 fiscal years.

(3) The provisions of this section may not be modified so as to reduce the security for any coal severance tax bonds while the bonds are outstanding.
