This exchange-traded fund (ETF) operates with an active management strategy. By its fundamental investment policy, the fund is typically committed to allocating at least 80% of its net assets to municipal bonds. Moreover, a core tenet of its strategy mandates that, under usual market conditions, a minimum of 80% of these net assets must be invested in municipal debt originating from the State of California, its local governmental bodies, or securities that provide an exemption from California state income tax.
