Credit Agency Warns Negative Outcome On Municipal Finances If Charter Ballot Question Passes

The city of Boston currently has a AAA bond rating, the highest possible. But that could change if the state's ballot Question 2 passes, according to an email sent to Boston and three other Massachusetts cities this week by Moody's Investors Service.

The email, first reported by The Boston Globe, warns that if the ballot measure to expand charter schools passes, that would be "credit negative" for Boston, Lawrence, Springfield and Fall River.
