The First Trust Municipal High Income ETF operates as an actively managed exchange-traded fund. Its primary goal is to generate income that is exempt from regular federal income taxes, with a secondary focus on achieving long-term capital appreciation. Typically, to achieve these aims, the Fund commits a minimum of 80% of its net assets (including any borrowed capital) to municipal debt securities. These are commonly referred to as "Municipal Securities" and are characterized by interest payments that are free from federal income tax.
