Illinois Refunding Bond and Receipt is a financial instrument issued by the State of Illinois to secure repayment of debt. The bond and receipt is issued in the form of a negotiable instrument, which is secured by the full faith and credit of the State of Illinois. The bond and receipt are typically issued when a municipality or other governmental body refinances existing debt or issues new debt. The bond and receipt are a form of government loan that is secured by the state's credit and is used to finance public projects. There are two types of Illinois Refunding Bonds and Receipts: General Obligation Bonds and Revenue Bonds. General Obligation Bonds are issued to finance public projects and are backed by the full faith and credit of the state. Revenue Bonds are issued to finance revenue-producing projects such as toll roads, bridges, and airports, and are typically backed by project revenues. The interest rate on the bond and receipt is based on the creditworthiness of the issuer, as well as the prevailing market interest rate. The repayment of the bond and receipt can be structured in a variety of ways, including principal-only payments, serial payments, amortized payments, or sinking funds.
