appropriate provisions for any liabilities
of the Fund. The Fund does not seek to distribute any predetermined amount of cash at maturity. During the maturing year of the Underlying Index (i.e., 2025), no new constituents are added and the Underlying Index
does not rebalance. In the last twelve months of operation, when the 2025 Bonds held by the Fund mature or are called, the proceeds are not reinvested in 2025 Bonds. Instead, the Fund will invest such proceeds in any
combination of variable rate demand obligations (“VRDOs”), certain derivatives (i.e., exchange-traded futures on fixed-income securities, fixed-income security indices, interest rates and currencies; exchange-traded and
over-the-counter (“OTC”) options on fixed-income securities, interest rates, currencies, interest rate futures contracts, and fixed-income security indices; exchange-traded and OTC interest rate and inflation swaps; and OTC total
return swaps and forwards on fixed-income securities, fixed-income security indices, and fixed-income security futures), exchange-traded funds (“ETFs”), including affiliated ETFs, affiliated money market
funds, cash or cash equivalents and investment-grade short-term commercial paper, as well as municipal bonds not included in the Underlying Index, but which the Adviser believes will help the Fund track the Underlying Index.
The Fund should not be confused with a target date fund, which has assets that are managed according to a particular glidepath that illustrates how its investment strategy
becomes increasingly conservative over time.
The Fund does not purchase all of the securities in the Underlying Index; instead, the Fund
utilizes a “sampling” methodology to seek to achieve its investment objective.
Concentration Policy.
The Fund will concentrate its investments (i.e., invest more than 25% of the value of its net
assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise
concentrate its investments in securities of issuers in any one industry or group of industries.
Principal Risks of Investing in the Fund
The following summarizes the principal risks of investing in the Fund.
The Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective.
Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value
of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Additionally, natural or environmental disasters, widespread disease or other public health
issues, war, military conflicts, acts of terrorism, economic crises or other events could result in increased premiums or discounts to the Fund’s net asset value (“NAV”).
Index Risk. Unlike many investment companies, the Fund
does not utilize an investing strategy that seeks returns in excess of the Underlying Index.
Therefore, the Fund would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming. Additionally, the Fund rebalances its portfolio in
accordance with the Underlying Index, and, therefore, any changes to the Underlying Index’s rebalance schedule will result in corresponding changes to the Fund’s rebalance schedule.
Municipal Securities Risk. Litigation, legislation or other political events, local business or economic conditions or the bankruptcy of
the issuer could have a significant effect on the ability of an issuer of municipal securities to
make payments of principal and/or interest. Political changes and uncertainties in the municipal market related to taxation, legislative changes or the rights of municipal security holders can significantly affect municipal securities. Because
many securities are issued to finance similar projects, especially those relating to education, health care, transportation and utilities, conditions in those sectors can affect the overall municipal market. In addition, changes in
the financial condition of an individual municipal issuer can affect the overall municipal market. If the Internal Revenue Service (“IRS”) determines that an issuer of a municipal security
has not complied with applicable tax
requirements, interest from the security could become taxable and the security could decline significantly in value.
Fixed-Income Securities Risk. Fixed-income securities are subject to interest rate risk and credit risk. Interest rate risk refers to
fluctuations in the value of a fixed-income security resulting from changes in the general level
of interest rates. When the general level of interest rates goes up, the prices of most fixed-income securities go down. When the general level of interest rates goes down, the prices of most fixed-income securities go up. Fixed-income securities with
longer maturities typically are more sensitive to changes in interest rates, making them more volatile than securities with shorter maturities. Credit risk refers to the possibility that the issuer of a security will be unable and/or
unwilling to make timely interest payments and/or repay the principal on its debt. Debt instruments are subject to varying degrees of credit risk, which may be reflected in credit ratings. There is a possibility that the
credit rating of a fixed-income security may be downgraded after purchase, which may occur quickly and without advance warning following sudden market downturns or unexpected developments involving an issuer, and which may
adversely affect the liquidity and value of the security.
Changing Fixed-Income Market Conditions Risk. Fluctuations in the federal funds and equivalent foreign interest rates or other changes to monetary policy or regulatory
actions may expose fixed-income markets to heightened volatility, perhaps suddenly and to a significant degree, and to reduced liquidity for certain fixed-income investments, particularly those with longer maturities, when rates
increase. Such changes and resulting increased volatility may adversely impact the Fund, including its operations and return potential. It is difficult to predict the impact of interest rate changes on various markets. In
addition, decreases in fixed-income dealer market-making capacity may also potentially lead to heightened volatility and reduced liquidity in the fixed-income markets. As a result, the value of the Fund's investments and share
price may decline. Changes in central bank policies and other governmental actions and political events within the U.S. and abroad may also, among other things, affect investor and consumer expectations and confidence in the
financial markets. This could result in higher than normal redemptions by APs (as defined herein), which could potentially increase the Fund’s portfolio turnover rate and transaction costs.
Tax Risk. There is no guarantee that the Fund's income will be exempt from federal or state income taxes. Events occurring after the date of issuance of a municipal bond or after
the Fund's acquisition of a municipal bond may result in a determination that interest on that bond is includible in gross income for federal income tax purposes retroactively to its date of issuance. Such a determination may
cause a portion of prior distributions by the Fund to its shareholders to be taxable to those shareholders in the year of receipt. Federal or state changes in income or alternative minimum tax rates or in the tax treatment of
municipal bonds may make municipal bonds less attractive as investments and cause them to lose value.
Industry Concentration Risk. In following its methodology, the Underlying Index from time to time may be concentrated to a significant
degree in securities of issuers operating in a single industry or industry group. To the extent
that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry
or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the
Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand in a particular industry; competition for resources;
adverse labor relations; political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of
