(a) There are established special funds of the state, known as the "Alaska clean water fund revenue bond redemption fund " and the "Alaska drinking water fund revenue bond redemption fund," which are trust funds for paying and securing the payment of the principal of and interest and redemption premium, if any, on the bonds and which shall be at all times completely segregated and set apart from all other funds of the state. The committee, on behalf of the state, may obligate and bind the state to set aside and pay into the bond redemption funds, on a monthly or other periodic basis, any part or parts of, or all of, or a fixed proportion of, or a fixed amount of the money in the Alaska clean water fund (AS 46.03.032 ) or the Alaska drinking water fund (AS 46.03.036) sufficient to pay the principal of and interest and redemption premium, if any, on the bonds and, if it considers it necessary, to set aside and maintain reserves for this purpose. The bond redemption funds shall be drawn upon only for the purpose of paying the principal of and interest and redemption premium, if any, on the bonds, together with related trustee fees, if any.
(b) Money in the bond redemption funds may be invested in the same manner and on the same conditions as permitted for investment of money belonging to the state or held in the treasury under AS 37.10.070; however, the committee may agree with the bondholders to further limit these investments. Earnings on investments must be retained in the bond redemption funds.
(c) Separate accounts may be created in the bond redemption funds for the purposes of paying and securing the bonds. The accounts may be combined for purposes of investment and for financial support to achieve the purposes of AS 37.15.570 (c).
