Credit Rating
Bonds that are traded in the open market are rated by one or more rating agencies. Ratings are forward looking opinions about credit risk. The agencies review the strength of the pledged revenue that will repay the debt, the financial strength of the funds involved in the debt issuance, and a variety of factors about the city including economic diversity, financial performance, existing debt burden, and financial management practices.
Rating Agency Scale
Based upon this information, the agency determines a risk level for the bonds and assigns it a designation from a scale with AAA as the prime quality, AA as high grade, etc. The city has used both Moody’s Investors Service and Standard and Poors. Top tier scales are shown in the following table. The city’s bonds and respective ratings are disclosed below the table.
