Standard and Poor’s, the bond rating agency that rates more than 80 percent of the nation’s municipal and corporate bonds, raised Braselton’s rating from BBB+ to A- in March. The rating is for the town’s water and sewerage system revenue bonds.

In assigning a rating for revenue bonds, the major rating agencies assess economy, debt structure, financial condition, demographic factors and management practices of the governing body and administration. Additionally an analysis is performed with respect to water and sewer system users and rates.

“A-” bonds are rated as favorable investments and considered to be upper-medium grade obligations, citing factors giving security to principal and interest structure.
