Fitch Ratings, one of the three agencies that evaluate government bonds, has upgraded its rating outlook for Suffolk from stable to positive.

The city’s rating from Fitch remains AA+ for the $102.9 million general obligation and refunding bonds the city will sell near the end of this month.

Fitch noted rating drivers including fiscal discipline, good debt management and a strong regional employment base, according to a news release from the city.

Look for a full story on the credit ratings later this week, after the other two rating agencies — Standard and Poor’s and Moody’s — release their evaluations of the city’s debt.
