The fund's primary objective is to achieve a comprehensive total return, derived from both current income generation and capital appreciation. It typically commits a minimum of 80% of its capital available for investment—referred to as "investable assets"—to master limited partnerships (MLPs) and related securities. "Investable assets" specifically include the fund's net holdings along with any borrowings used for investment purposes. However, if the fund borrows capital for non-investment reasons, such as managing anticipated redemptions, these investable assets would be less than its total asset base.
