DALLAS (Standard&Poor's) Oct. 26, 2015--Standard&Poor's Ratings Services assigned its 'AAA' long-term rating to Williamson County, Texas' series 2015A limited-tax refunding bonds. At the same time, Standard&Poor's affirmed its 'AAA' long-term rating and underlying rating (SPUR) on the county's general obligation (GO) debt outstanding. The outlook is stable. "The ratings reflect our assessment of the following factors of the county strong economy, very strong management, strong budgetary performance, very strong budgetary flexibility, very strong liquidity, and very weak debt and contingent liability position," said Standard&Poor's credit analyst Lauren Spalten. County officials will use bond proceeds to refund a portion of the county's outstanding GO debt for savings purposes. RELATED CRITERIA AND RESEARCH Related
