7-12-4248. Operation and use of supplemental revolving fund. (1) Money in the supplemental revolving fund shall first be loaned to the various district funds whose bonds are guaranteed under 7-12-4241 through 7-12-4258 to make up any deficiency in such funds.

(2) In event of any further deficiency in such funds, the money in the revolving fund created under 7-12-4221 through 7-12-4228 may be loaned to make good such deficiency pursuant to the provisions of those sections.

(3) In event that the deficit exceeds the money in the supplemental revolving fund, then the money in the revolving fund may be similarly loaned until the deficiency has been made good.

(4) The authorizing resolution may provide that bonds shall become due in accordance with a plan of redemption prior to the stated maturity date. Both revolving funds shall thereafter have concurrent liens on the unpaid assessments and the moneys in the improvement district fund for all such advances, provided that such advances shall not be returned so long as any principal or interest on bonds issued under 7-12-4241 through 7-12-4258 remains unpaid.
