All moneys borrowed under the authority of this Act, except money borrowed by school districts having a population of more than 500,000 inhabitants, shall be paid to the school treasurer of the district. The treasurer shall, before receiving any of the money, execute a bond with a surety company authorized to do business in this State, as surety, payable to the school board of the district in Class I county school units or township trustees in Class II county school units and conditioned upon the faithful discharge of his duties, except that the bond required of the school treasurer of a school district which is located in a Class II county school unit but which no longer is subject to the jurisdiction and authority of a township treasurer or trustees of schools of a township because the district has withdrawn from the jurisdiction and authority of the township treasurer and trustees of schools of the township or because those offices have been abolished as provided in subsection (b) or (c) of Section 5-1 shall be payable to the school board of such district and conditioned upon the faithful discharge of his duties. The bond shall be submitted for approval or rejection to the school board of the district or to the township trustees to which such bond is payable. The penalty of the bond or bonds shall be an amount no less than 10% of the amount of such bond issue, whether individuals act as surety or whether the surety is given by a surety company authorized to transact business in this State. The bond shall be in substantially the same form as that required by Section 8-2 of this Act and when so given shall fully describe the bond issue which it specifically covers and shall remain in force until the funds of the bond issue are taken into account in determining the penalty amount for the surety bond required by Section 8-2 of this Code. Upon receiving such moneys the treasurer shall deliver the bonds issued therefor to the persons entitled to receive them, and shall credit the funds received to the district issuing the bonds. The treasurer shall record the amount received for each bond issued. When any bonds are paid the treasurer shall cancel them and shall enter, against the record of the bonds, the words, "paid and cancelled the.... day of...., ....," filling the blanks with the day, month, and year corresponding to the date of payment.
