Miss. Code § 29-3-113
The principal fund shall be a permanent township fund which shall consist of funds heretofore or hereafter derived from certain uses or for certain resources of school trust lands which shall be invested and, except as otherwise provided in this section, only the interest and income derived from such funds shall be expendable by the school district.
The principal fund shall consist of:
It shall be the duty of the Board of Education to keep the principal fund invested in any direct obligation issued by or guaranteed in full as to principal and interest by the United States of America or in certificates of deposit issued by a qualified depository of the State of Mississippi as approved by the State Treasurer. The certificates of deposit may bear interest at any rate per annum which may be mutually agreed upon but in no case shall said rate be less than that paid on passbook savings.
The Board of Education is authorized to invest the funds in interest bearing deposits or other obligations of the types described in Section 27-105-33 or in any other type investment in which any other political subdivision of the State of Mississippi may invest, except that one hundred percent (100%) of the funds are authorized to be invested. For the purposes of investment, the principal fund of each township may be combined into one or more district accounts; however, the docket book of the county superintendent shall at all times reflect the proper source of such funds. Provided that funds received from the sale of timber shall be placed in a separate principal fund account, and may be expended for any of the purposes authorized by law.
The Board of Education shall have authority to borrow such funds at a rate of interest not less than four percent (4%) per annum and for a term not exceeding twenty (20) years, for the erection, equipment or repair of said district schools, to provide local funds for any building project approved by the State Board of Education or to provide additional funds for forest stand improvement as set forth in Section 29-3-47. In addition, the board may borrow the funds under the same interest restrictions for a term not exceeding ten (10) years to provide funds for the purchase of school buses. The Board of Education of any school district in any county that has an aggregate amount of assets in its principal fund in excess of Five Million Dollars ($5,000,000.00) may deduct an amount not to exceed Five Hundred Thousand Dollars ($500,000.00) for the purpose of covering the cost of asbestos removal from school district buildings. Such asbestos removal shall be construed to constitute the repair of school district facilities as prescribed in Section 29-3-115.
No school land trust funds may be expended after the annual payment date until the payment is made on such loan. Once a district is current on its loan payments, the district may spend expendable trust funds earned or accumulated in previous years for any purpose for which expendable trust funds may be spent. The annual payment can be made from any funds available to the school district except total funding formula funds.
It shall be unlawful for the Board of Education to borrow any sixteenth section school funds in any other manner than that prescribed herein, and if any such funds shall be borrowed or invested in any other manner, any officer concerned in making such loan and investment or suffering the same to be made in violation of the provisions of this section shall be liable personally and on his official bond for the safety of the funds so loaned.
