The Fund invests primarily in debt securities issued by Massachusetts municipalities. The ability of the issuers of the debt securities to meet their obligations may be affected by economic developments in a specific industry or municipality.

The aggregate percentage insured by an individual financial institution ranged from 2.4% to 28.3% of total investments.
