Fund may be unable to sell a restricted
security on short notice or may be able to sell them only at a price below current value. It may
be more difficult to determine a market value for a restricted security. Also, a Fund may get only limited information about the issuer of a restricted security, so it may be less able to predict a loss. In addition, if Fund
management receives material non-public information about the issuer, the Fund may as a result be
unable to sell the securities. Certain restricted securities may involve a high degree of business and financial risk and may result in substantial losses.
Government Securities Risk. The Fund invests in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities (such as securities issued by
Ginnie Mae, Fannie Mae, or Freddie Mac). U.S. government securities are subject to market risk,
interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States, are guaranteed only as to
the timely payment of interest and principal when held to maturity and the market prices for such
securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would
result in losses to the Fund. Securities issued or guaranteed by U.S. government-related
organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government will provide financial support. Therefore, U.S.
government-related organizations may not have the funds to meet their payment obligations in the
future. U.S. government securities include zero-coupon securities, which tend to be subject to greater market risk than interest-paying securities of similar maturities.
Cash Transactions Risk. Unlike certain ETFs, the Fund may effect creations and redemptions in cash or partially in cash. Therefore, it may be required to sell portfolio
securities and subsequently recognize gains on such sales that the Fund might not have recognized
if it were to distribute portfolio securities in-kind. As such, investments in Shares may be less tax-efficient than an investment in an ETF that distributes portfolio securities entirely in-kind.
General Market Risk.
Economies and financial markets throughout the world are becoming increasingly interconnected,
which increases the likelihood that events or conditions in one country or region will adversely
impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other
asset classes due to a number of factors, including inflation (or expectations for inflation),
deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions
and other trade barriers, regulatory events, other governmental trade or market control programs
and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or
events, country instability, and infectious disease epidemics or pandemics.
Industry and Sector Focus Risk. At times, the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of
issuers in a particular
industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or
supplies, contagion risk within a particular industry or sector or to other industries or
sectors, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or
sector, the value of the Fund’s Shares may fluctuate in response to events affecting that
industry or sector.
ETF Shares Trading Risk. Shares are listed for trading on the Cboe BZX Exchange, Inc. (the Exchange) and are bought and sold in the secondary market at market prices. The market prices of Shares are expected to fluctuate, in some
cases materially, in response to changes in the Fund’s NAV, the intraday value of the
Fund’s holdings and supply and demand for Shares. The adviser cannot predict whether Shares will trade above, below or at their NAV. Disruptions to creations and redemptions, the existence of significant market
volatility or potential lack of an active trading market for the Shares (including through a
trading halt), as well as other factors, may result in the Shares trading significantly above (at a premium) or below (at a discount) to NAV or to the intraday value of the Fund’s holdings. During such periods, you
may incur significant losses if you sell your Shares.
The securities held by the Fund may be traded in markets that close at a different time than the Exchange.
Liquidity in those securities may be reduced after the applicable closing times. Accordingly,
during the time when the Exchange is open but after the applicable market closing, fixing or settlement times, bid-ask spreads on the Exchange and the corresponding premium or discount to the Shares’ NAV may
widen.
Authorized Participant Concentration Risk. Only an authorized participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of intermediaries that act as authorized participants
and none of these authorized participants is or will be obligated to engage in creation or
redemption transactions. To the extent that these intermediaries exit the business or are unable to or choose not to proceed with creation and/or redemption orders with respect to the Fund and no other authorized participant
creates or redeems, Shares may trade at a discount to NAV and possibly face trading halts and/or
delisting.
Floating and Variable Rate Securities Risk. Floating and variable rate securities provide for a periodic adjustment in the interest rate paid on the securities. The rate
adjustment intervals may be regular and range from daily up to annually, or may be based on an
event, such as a change in the prime rate. Floating and variable rate securities may be subject to greater liquidity risk than other debt securities, meaning that there may be limitations on the Fund’s ability to sell the
securities at any given time. Such securities also may lose value.
Concentration Risk. The Fund may invest more than 25% of its Assets in municipal securities, the interest upon which is paid from revenues of projects within a single
sector, such as housing and healthcare. As a result, the Fund could be more susceptible to
developments which affect those sectors.
Net Asset Value Risk. The Fund is not a money market fund. Therefore, the Fund does not attempt to maintain a stable NAV and is not subject to the rules that govern the diversity, quality, maturity, liquidity and other features of
securities that money
