S&P Global Ratings assigned its 'AA-' long-term rating to Jefferson County School District Finance Corp., Ky.'s series 2017A school building revenue bonds, issued for the Jefferson County Board of Education (the district). At the same time, we affirmed our 'AA-' long-term rating and underlying rating (SPUR) on the corporation's existing appropriation debt supported by the district, and our 'AA' issuer credit rating (ICR) on the district. The outlook is stable. The bonds are secured by the district's lease rental payments, which it makes from legally available revenue under a renewable, annually terminable lease. A statutory mortgage lien on the various projects also secures the bonds. The rating reflects our view of the district's agreement to appropriate annual debt service payments.
