Industry description
The investment seeks a high level of income exempt from federal income taxes by investing primarily in long-term investment-grade municipal securities.
The fund normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in municipal bonds whose income is exempt from regular federal income taxes. Any derivatives that provide exposure to the investment focus suggested by the fund’s name, or to one or more market risk factors associated with the investment focus suggested by the fund’s name, are counted (as applicable) toward compliance with the fund’s 80% investment policy.
