The general assembly finds and declares that because of differences in the timing of the receipt of tax and other revenues and the expenditure of funds by the state, the state has been unable to remain timely on its obligations, including its payments of school aid; the untimely payment of state aid has created a hardship for schools by increasing their costs and hindering their ability to remain timely on their obligations; it would be advantageous to the state to be able to issue notes in anticipation of its tax and other revenues in order to coordinate its cash flow; and pending their use, the proceeds of notes issued in anticipation of tax and other revenues should be invested in order to pay the cost of issuing the notes and as a benefit to the state. It is the purpose of this section and section 12.26 to enable the state to make timely payments of its obligations, including its school aid payments, by securing funds through the issuance of notes in anticipation of the state’s tax and other revenues.
