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.
Normally, at least 80% of the fund’s income will be exempt from 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.
