The report states Johnson City has a "very high quality" credit position, the city said. Johnson City holds a Moodyâs Aa2 rating, which exceeds the median rating of Aa3 for U.S. cities. The annual report, the city said, cites a sound financial position, an ample tax base, a moderate wealth and income profile, and mid-ranged debt and pension liabilities among the key credit factors in this determination. âWe are thrilled that Moodyâs has acknowledged our strong financial position in this report,â Finance Director Janet Jennings said in the press release. âThe Board of Commissioners and city staff work diligently to maintain high quality credit and moderate debt liabilities while providing top quality services to the community.â
