The BlackRock Taxable Municipal Bond Trust (BBN) is a mutual fund that invests in taxable municipal bonds. These bonds are issued by state and local governments to fund various projects and are subject to federal income tax. The fund is managed by BlackRock, a leading investment management company, and aims to provide investors with a steady stream of income through interest payments from the bonds. BBN may also provide potential tax benefits for investors, as the interest earned from municipal bonds is typically exempt from state and local taxes. This fund is suitable for investors seeking a combination of income and potential tax advantages.
