BKMS

The fund seeks to maximize current income exempt from federal income tax to the extent consistent with the preservation of capital. To pursue its goal, the fund normally invests at least 80% of its net assets, plus any borrowings for investment purposes, in municipal bonds that provide income exempt from U.S. federal income tax. The fund typically invests in municipal and taxable bonds rated investment grade (i.e., Baa3/BBB- or higher) at the time of purchase or, if unrated, deemed of comparable quality by the fund’s sub-adviser, Insight North America LLC. Generally, the average effective duration of the fund's portfolio will not exceed three years. The fund may invest in individual municipal and taxable bonds of any maturity or duration. Duration is an indication of an investment's "interest rate risk," or how sensitive a bond or the fund's portfolio may be to changes in interest rates. Generally, the longer a bond's duration, the more likely it is to react to interest rate fluctuations and the greater its long-term risk/return potential. The fund’s liquid ETF structure allows investors to buy or sell any time the market is open.
