Pledged Revenues: The bonds are secured solely by a pledge of and first lien on the net revenues of the turnpike system, which consist of gross revenues less the cost of operation and maintenance. The Department of Transportation has covenanted to provide for the payment of costs of operation and maintenance from certain available moneys in the State Transportation Trust Fund (“STTF”), which is funded by motor fuel taxes, motor vehicle license taxes, various other transportation‐related taxes, fees and surcharges, federal aid, interest earnings and other miscellaneous revenues. In effect, the covenant makes 100 percent of turnpike revenues available for debt service. The turnpike system is ultimately required to reimburse the STTF for any operation and maintenance costs which were advanced, from the turnpike general reserve fund. The bonds are not a general obligation or indebtedness of the State of Florida, and the full faith and credit of the State of Florida is not pledged to payment of the bonds.
