Standard&Poor's Ratings Services has assigned its 'AA' rating to Orange County, Fla.'s series 2012C sales tax revenue refunding bonds. At the same time, Standard&Poor's affirmed its 'AA' rating on the county's existing parity sales tax debt. The outlook is stable. The first-lien pledge on the county's apportionment of the half-cent sales tax secures the bonds, excluding the county's discretionary sales tax.

The county will use bond proceeds to refund its series 2002A sales
