Fixed income investments are also subject to credit risk, which is the risk that issuers of the fund&#x2019;s investments may default on payment of interest or principal. Fixed income investments may be more susceptible to downgrades or defaults during economic downturns or other periods of economic stress. Interest rate risk is generally greater for longer-term fixed income securities, and credit risk is generally greater for below-investment-grade fixed income securities, which can be more sensitive to changes in markets, credit conditions, and interest rates, and may be considered speculative. &lt;/div&gt;</oef:RiskTextBlock>

Consequently, the fund may be more vulnerable to fluctuations in the values of the securities it holds than a fund that invests more broadly. The fund&#x2019;s performance will be closely tied to the economic and political conditions in California, and can be more volatile than the performance of a more geographically diversified fund. To the extent the fund invests in securities of issuers located outside of California, the fund may also be exposed to the risks affecting other states. Certain provisions of the California Constitution and state statutes limit the taxing and spending authority of California&#x2019;s government entities, which could impair the ability of California issuers to pay principal and/or interest on their obligations. Interest the fund receives might be taxable. &lt;/div&gt;</oef:RiskTextBlock>

The net asset value of the fund will generally fluctuate with changes in the market value of the fund&#x2019;s holdings. The fund&#x2019;s shares can be bought and sold in the secondary market at market prices. Disruptions to creations and redemptions, the existence of extreme market volatility or potential lack of an active trading market for the fund&#x2019;s shares may result in the fund&#x2019;s shares trading significantly above (at a premium) or below (at a discount) net asset value or the intraday value of the fund&#x2019;s holdings. In addition, in stressed market conditions or periods of market disruption or volatility, the market for fund shares may become less liquid in response to deteriorating liquidity in the markets for the fund&#x2019;s underlying portfolio holdings. &lt;/div&gt;</oef:RiskTextBlock>

There can be no assurance that an active trading market will develop or be maintained or that the market for fund shares will operate as intended, which could lead to the fund&#x2019;s shares trading at wider spreads and larger premiums and discounts to net asset value than other actively managed ETFs. As a result, it may cost investors more to trade fund shares than shares of other ETFs. There is no guarantee that the fund will be able to attract market makers and authorized participants. Market makers and authorized participants are not obligated to make a market in the fund&#x2019;s shares or to submit purchase and redemption orders for creation units. The market prices of the fund&#x2019;s shares are expected to fluctuate, in some cases materially, in response to changes in the fund&#x2019;s net asset value, the intraday value of the fund&#x2019;s holdings and supply and demand for the fund&#x2019;s shares. The Investment Manager cannot predict whether the fund&#x2019;s shares will trade above, below or at their net asset value or the intraday value of the fund&#x2019;s holdings. During such periods, investors may incur significant losses if they sell shares. &lt;/div&gt;&lt;div style="margin-top:0pt;margin-bottom:0pt;font-size:9pt;font-family:arial;"&gt;The securities held by the fund may be traded in markets that close at a different time than the exchange on which the fund&#x2019;s shares are listed. 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&#x2019; net asset value may widen. &lt;/div&gt;</oef:RiskTextBlock>

The fund may be an investment option for mutual funds that are managed by the Investment Manager and its affiliates as &#x201c;funds of funds.&#x201d; Additionally, other investors from time to time may make substantial investments in the fund. Such shareholders may at times be considered to control the fund. In addition, a large number of shareholders may collectively purchase or redeem fund shares in large amounts rapidly or unexpectedly. Large shareholder transactions may adversely affect the fund&#x2019;s liquidity and net assets. These redemptions may also adversely affect the fund&#x2019;s performance if the fund is forced to sell securities, which may also increase the fund&#x2019;s brokerage costs. &lt;/div&gt;</oef:RiskTextBlock>

The fund may have a limited number of financial institutions that act as authorized participants, none of which are obligated to engage in creation and/or redemption transactions. To the extent that those authorized participants do not engage in creation and redemption orders, there may be a significantly diminished trading market for fund shares or fund shares may trade at a discount (or premium) to net asset value and possibly face trading halts and/or de-listing. &lt;/div&gt;</oef:RiskTextBlock>

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.

The net asset value of the fund will generally fluctuate with changes in the market value of the fund&#x2019;s holdings. The fund&#x2019;s shares can be bought and sold in the secondary market at market prices. Disruptions to creations and redemptions, the existence of extreme market volatility or potential lack of an active trading market for the fund&#x2019;s shares may result in the fund&#x2019;s shares trading significantly above (at a premium) or below (at a discount) net asset value or the intraday value of the fund&#x2019;s holdings. In addition, in stressed market conditions or periods of market disruption or volatility, the market for fund shares may become less liquid in response to deteriorating liquidity in the markets for the fund&#x2019;s underlying portfolio holdings.&lt;/div&gt; </oef:RiskTextBlock>

There can be no assurance that an active trading market will develop or be maintained or that the market for fund shares will operate as intended, which could lead to the fund&#x2019;s shares trading at wider spreads and larger premiums and discounts to net asset value than other actively managed ETFs. As a result, it may cost investors more to trade fund shares than shares of other ETFs. There is no guarantee that the fund will be able to attract market makers and authorized participants. Market makers and authorized participants are not obligated to make a market in the fund&#x2019;s shares or to submit purchase and redemption orders for creation units. The market prices of the fund&#x2019;s shares are expected to fluctuate, in some cases materially, in response to changes in the fund&#x2019;s net asset value, the intraday value of the fund&#x2019;s holdings and supply and demand for the fund&#x2019;s shares. The Investment Manager cannot predict whether the fund&#x2019;s shares will trade above, below or at their net asset value or the intraday value of the fund&#x2019;s holdings. During such periods, investors may incur significant losses if they sell shares.&lt;/div&gt;  &lt;div style="margin-top: 6pt; margin-bottom: 0pt; font-size: 9pt; font-family: arial;"&gt;The securities held by the fund may be traded in markets that close at a different time than the exchange on which the fund&#x2019;s shares are listed. 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&#x2019; net asset value may widen.&lt;/div&gt; </oef:RiskTextBlock>

Large shareholder transactions may adversely affect the fund&#x2019;s liquidity and net assets. These redemptions may also adversely affect the fund&#x2019;s performance if the fund is forced to sell securities, which may also increase the fund&#x2019;s brokerage costs.&lt;/div&gt; </oef:RiskTextBlock>

The fund may have a limited number of financial institutions that act as authorized participants, none of which are obligated to engage in creation and/or redemption transactions. To the extent that those authorized participants do not engage in creation and redemption orders, there may be a significantly diminished trading market for fund shares or fund shares may trade at a discount (or premium) to net asset value and possibly face trading halts and/or de-listing.&lt;/div&gt; </oef:RiskTextBlock>

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.

There can be no assurance that an active trading market will develop or be maintained or that the market for fund shares will operate as intended, which could lead to the fund&#x2019;s shares trading at wider spreads and larger premiums and discounts to net asset value than other actively managed ETFs. As a result, it may cost investors more to trade fund shares than shares of other ETFs. There is no guarantee that the fund will be able to attract market makers and authorized participants. Market makers and authorized participants are not obligated to make a market in the fund&#x2019;s shares or to submit purchase and redemption orders for creation units. The market prices of the fund&#x2019;s shares are expected to fluctuate, in some cases materially, in response to changes in the fund&#x2019;s net asset value, the intraday value of the fund&#x2019;s holdings and supply and demand for the fund&#x2019;s shares. The Investment Manager cannot predict whether the fund&#x2019;s shares will trade above, below or at their net asset value or the intraday value of the fund&#x2019;s holdings. During such periods, investors may incur significant losses if they sell shares.&lt;span style="font-weight:bold"&gt; &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:8pt;margin-bottom:0pt;font-size:10pt;font-family:arial;"&gt;The securities held by the fund may be traded in markets that close at a different time than the exchange on which the fund&#x2019;s shares are listed. 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&#x2019; net asset value may widen. &lt;/div&gt;</oef:RiskTextBlock>

The fund may be an investment option for mutual funds that are managed by the Investment Manager and its affiliates as &#x201c;funds of funds.&#x201d; Additionally, other investors from time to time may make substantial investments in the fund. Such shareholders may at times be considered to control the fund. In addition, a large number of shareholders may collectively purchase or redeem fund shares in large amounts rapidly or unexpectedly. Large shareholder transactions may adversely affect the fund&#x2019;s liquidity and net assets. These redemptions may also adversely affect the fund&#x2019;s performance if the fund is forced to sell securities, which may also increase the fund&#x2019;s brokerage costs.&lt;span style="font-weight:bold"&gt; &lt;/span&gt;&lt;/div&gt;</oef:RiskTextBlock>

The fund may have a limited number of financial institutions that act as authorized participants, none of which are obligated to engage in creation and/or redemption transactions. To the extent that those authorized participants do not engage in creation and redemption orders, there may be a significantly diminished trading market for fund shares or fund shares may trade at a discount (or premium) to net asset value and possibly face trading halts and/or de-listing.&lt;span style="font-weight:bold"&gt; &lt;/span&gt;&lt;/div&gt;</oef:RiskTextBlock>

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 the fund&#x2019;s shares may be less tax-efficient than an investment in an ETF that distributes portfolio securities entirely in-kind.&lt;span style="font-weight:bold"&gt; &lt;/span&gt;&lt;/div&gt;</oef:RiskTextBlock>

The fund has the same investment goal and substantially similar strategies as the Predecessor Fund. However, the fund has a lower net expense ratio than each share class of the Predecessor Fund.

There can be no assurance that an active trading market will develop or be maintained or that the market for fund shares will operate as intended, which could lead to the fund&#x2019;s shares trading at wider spreads and larger premiums and discounts to net asset value than other actively managed ETFs. As a result, it may cost investors more to trade fund shares than shares of other ETFs. There is no guarantee that the fund will be able to attract market makers and authorized participants. Market makers and authorized participants are not obligated to make a market in the fund&#x2019;s shares or to submit purchase and redemption orders for creation units.

The Investment Manager cannot predict whether the fund&#x2019;s shares will trade above, below or at their net asset value or the intraday value of the fund&#x2019;s holdings.

Simultaneous with the fund&#x2019;s commencement of operations, which is anticipated to occur on or about October 27, 2025, the fund will acquire the assets and assume the liabilities of the Putnam New York Tax Exempt Income Fund (the &#x201c;Predecessor Fund&#x201d;) in a reorganization (the &#x201c;Reorganization&#x201d;).

The fund has the same investment goal and substantially similar strategies as the Predecessor Fund. However, the fund has a lower net expense ratio than each share class of the Predecessor Fund. As a result, the performance returns of the fund for the periods shown would have been different than those of the Predecessor Fund.

The Investment Manager cannot predict whether the fund&#x2019;s shares will trade above, below or at their net asset value or the intraday value of the fund&#x2019;s holdings.

This investment policy cannot be changed without the approval of the fund&#x2019;s shareholders. Interest income from private activity bonds may be subject to federal AMT for individuals.

Fixed income investments are also subject to credit risk, which is the risk that issuers of the fund&#x2019;s investments may default on payment of interest or principal. Fixed income investments may be more susceptible to downgrades or defaults during economic downturns or other periods of economic stress. Interest rate risk is generally greater for longer-term fixed income securities, and credit risk is generally greater for below-investment-grade fixed income securities, which can be more sensitive to changes in markets, credit conditions, and interest rates, and may be considered speculative. &lt;/div&gt;</oef:RiskTextBlock>

Consequently, the fund may be more vulnerable to fluctuations in the values of the securities it holds than a fund that invests more broadly.

Under normal circumstances, the fund invests at least 80% of the fund&#x2019;s net assets in tax-exempt investments. Tax-exempt investments are issued by or for states, territories or possessions of the United States or by their political subdivisions, agencies, authorities or other government entities, and the income from these investments is exempt from both federal and Minnesota personal income tax. This investment policy cannot be changed without the approval of the fund&#x2019;s shareholders. Interest income from private activity bonds may be subject to federal AMT for individuals. As a policy that cannot be changed without the approval of fund shareholders, the fund cannot include these investments for the purpose of complying with the 80% investment policy described above. &lt;/div&gt;&lt;div style="margin-top:6pt;margin-bottom:0pt;font-size:9pt;font-family:arial;"&gt;The fund may invest up to 25% of its total assets in below-investment-grade investments, which are sometimes referred to as &#x201c;junk bonds.&#x201d; However, the fund will not invest in investments that are rated lower than BB or its equivalent by each organization rating the investment, or are unrated securities that the Investment Manager believes are of comparable quality. The fund will not necessarily sell an investment if its rating is reduced after purchase. &lt;/div&gt;&lt;div style="margin-top:6pt;margin-bottom:0pt;font-size:9pt;font-family:arial;"&gt;The Investment Manager may consider, among other factors, credit, interest rate and prepayment risks, as well as general market conditions, when deciding whether to buy or sell investments. &lt;/div&gt;</oef:StrategyNarrativeTextBlock>

Fixed income investments are also subject to credit risk, which is the risk that issuers of the fund&#x2019;s investments may default on payment of interest or principal. Fixed income investments may be more susceptible to downgrades or defaults during economic downturns or other periods of economic stress. Interest rate risk is generally greater for longer-term fixed income securities, and credit risk is generally greater for below-investment-grade fixed income securities, which can be more sensitive to changes in markets, credit conditions, and interest rates, and may be considered speculative. &lt;span style="font-weight:bold"&gt; &lt;/span&gt;&lt;/div&gt;</oef:RiskTextBlock>

Consequently, the fund may be more vulnerable to fluctuations in the values of the securities it holds than a fund that invests more broadly. The fund&#x2019;s performance will be closely tied to the economic and political conditions in Minnesota and can be more volatile than the performance of a more geographically diversified fund. To the extent the fund invests in securities of issuers located outside of Minnesota, the fund may also be exposed to the risks affecting other states. Interest the fund receives might be taxable.&lt;span style="font-weight:bold"&gt; &lt;/span&gt;&lt;/div&gt;</oef:RiskTextBlock>

The net asset value of the fund will generally fluctuate with changes in the market value of the fund&#x2019;s holdings. The fund&#x2019;s shares can be bought and sold in the secondary market at market prices. Disruptions to creations and redemptions, the existence of extreme market volatility or potential lack of an active trading market for the fund&#x2019;s shares may result in the fund&#x2019;s shares trading significantly above (at a premium) or below (at a discount) net asset value or the intraday value of the fund&#x2019;s holdings. In addition, in stressed market conditions or periods of market disruption or volatility, the market for fund shares may become less liquid in response to deteriorating liquidity in the markets for the fund&#x2019;s underlying portfolio holdings.&lt;span style="font-weight:bold"&gt; &lt;/span&gt;&lt;/div&gt;</oef:RiskTextBlock>

There can be no assurance that an active trading market will develop or be maintained or that the market for fund shares will operate as intended, which could lead to the fund&#x2019;s shares trading at wider spreads and larger premiums and discounts to net asset value than other actively managed ETFs. As a result, it may cost investors more to trade fund shares than shares of other ETFs. There is no guarantee that the fund will be able to attract market makers and authorized participants. Market makers and authorized participants are not obligated to make a market in the fund&#x2019;s shares or to submit purchase and redemption orders for creation units. The market prices of the fund&#x2019;s shares are expected to fluctuate, in some cases materially, in response to changes in the fund&#x2019;s net asset value, the intraday value of the fund&#x2019;s holdings and supply and demand for the fund&#x2019;s shares. The Investment Manager cannot predict whether the fund&#x2019;s shares will trade above, below or at their net asset value or the intraday value of the fund&#x2019;s holdings. During such periods, investors may incur significant losses if they sell shares.&lt;span style="font-weight:bold"&gt; &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;margin-bottom:0pt;font-size:9pt;font-family:arial;"&gt;The securities held by the fund may be traded in markets that close at a different time than the exchange on which the fund&#x2019;s shares are listed. 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 &lt;/div&gt;&lt;div style="margin-top:0pt;margin-bottom:0pt;font-size:9pt;font-family:arial;"&gt; exchange and the corresponding premium or discount to the shares&#x2019; net asset value may widen. &lt;/div&gt;</oef:RiskTextBlock>

The fund may be an investment option for mutual funds that are managed by the Investment Manager and its affiliates as &#x201c;funds of funds.&#x201d; Additionally, other investors from time to time may make substantial investments in the fund. Such shareholders may at times be considered to control the fund. In addition, a large number of shareholders may collectively purchase or redeem fund shares in large amounts rapidly or unexpectedly. Large shareholder transactions may adversely affect the fund&#x2019;s liquidity and net assets. These redemptions may also adversely affect the fund&#x2019;s performance if the fund is forced to sell securities, which may also increase the fund&#x2019;s brokerage costs.&lt;span style="font-weight:bold"&gt; &lt;/span&gt;&lt;/div&gt;</oef:RiskTextBlock>

The fund may have a limited number of financial institutions that act as authorized participants, none of which are obligated to engage in creation and/or redemption transactions. To the extent that those authorized participants do not engage in creation and redemption orders, there may be a significantly diminished trading market for fund shares or fund shares may trade at a discount (or premium) to net asset value and possibly face trading halts and/or de-listing.&lt;span style="font-weight:bold"&gt; &lt;/span&gt;&lt;/div&gt;</oef:RiskTextBlock>

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 the fund&#x2019;s shares may be less tax-efficient than an investment in an ETF that distributes portfolio securities entirely in-kind.&lt;span style="font-weight:bold"&gt; &lt;/span&gt;&lt;/div&gt;</oef:RiskTextBlock>

Fixed income investments are also subject to credit risk, which is the risk that issuers of the fund&#x2019;s investments may default on payment of interest or principal. Fixed income investments may be more susceptible to downgrades or defaults during economic downturns or other periods of economic stress. Interest rate risk is generally greater for longer-term fixed income securities, and credit risk is generally greater for below-investment-grade fixed income securities, which can be more sensitive to changes in markets, credit conditions, and interest rates, and may be considered speculative. &lt;/div&gt;</oef:RiskTextBlock>

Consequently, the fund may be more vulnerable to fluctuations in the values of the securities it holds than a fund that invests more broadly. The fund&#x2019;s performance will be closely tied to the economic and political conditions in New Jersey and can be more volatile than the performance of a more geographically diversified fund. To the extent the fund invests in securities of issuers located outside of New Jersey, the fund may also be exposed to the risks affecting other states.

The net asset value of the fund will generally fluctuate with changes in the market value of the fund&#x2019;s holdings. The fund&#x2019;s shares can be bought and sold in the secondary market at market prices. Disruptions to creations and redemptions, the existence of extreme market volatility or potential lack of an active trading market for the fund&#x2019;s shares may result in the fund&#x2019;s shares trading significantly above (at a premium) or below (at a discount) net asset value or the intraday value of the fund&#x2019;s holdings.

There can be no assurance that an active trading market will develop or be maintained or that the market for fund shares will operate as intended, which could lead to the fund&#x2019;s shares trading at wider spreads and larger premiums and discounts to net asset value than other actively managed ETFs. As a result, it may cost investors more to trade fund shares than shares of other ETFs. There is no guarantee that the fund will be able to attract market makers and authorized participants. Market makers and authorized participants are not obligated to make a market in the fund&#x2019;s shares or to submit purchase and redemption orders for creation units. The market prices of the fund&#x2019;s shares are expected to fluctuate, in some cases materially, in response to changes in the fund&#x2019;s net asset value, the intraday value of the fund&#x2019;s holdings and supply and demand for the fund&#x2019;s shares. The Investment Manager cannot predict whether the fund&#x2019;s shares will trade above, below or at their net asset value or the intraday value of the fund&#x2019;s holdings.

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 &lt;/div&gt;&lt;div style="margin-top:0pt;margin-bottom:0pt;font-size:9pt;font-family:arial;"&gt; exchange and the corresponding premium or discount to the shares&#x2019; net asset value may widen. &lt;/div&gt;</oef:RiskTextBlock>

The fund&#x2019;s performance will be closely tied to the economic and political conditions in Ohio and can be more volatile than the performance of a more geographically diversified fund. To the extent the fund invests in securities of issuers located outside of Ohio, the fund may also be exposed to the risks affecting other states.

The net asset value of the fund will generally fluctuate with changes in the market value of the fund&#x2019;s holdings. The fund&#x2019;s shares can be bought and sold in the secondary market at market prices. Disruptions to creations and redemptions, the existence of extreme market volatility or potential lack of an active trading market for the fund&#x2019;s shares may result in the fund&#x2019;s shares trading significantly above (at a premium) or below (at a discount) net asset value or the intraday value of the fund&#x2019;s holdings. In addition, in stressed market conditions or periods of market disruption or volatility, the market for fund shares may become less liquid in response to deteriorating liquidity in the markets for the fund&#x2019;s underlying portfolio holdings.&lt;span style="font-weight:bold"&gt; &lt;/span&gt;&lt;/div&gt;</oef:RiskTextBlock>

There can be no assurance that an active trading market will develop or be maintained or that the market for fund shares will operate as intended, which could lead to the fund&#x2019;s shares trading at wider spreads and larger premiums and discounts to net asset value than other actively managed ETFs. As a result, it may cost investors more to trade fund shares than shares of other ETFs. There is no guarantee that the fund will be able to attract market makers and authorized participants. Market makers and authorized participants are not obligated to make a market in the fund&#x2019;s shares or to submit purchase and redemption orders for creation units. The market prices of the fund&#x2019;s shares are expected to fluctuate, in some cases materially, in response to changes in the fund&#x2019;s net asset value, the intraday value of the fund&#x2019;s holdings and supply and demand for the fund&#x2019;s shares. The Investment Manager cannot predict whether the fund&#x2019;s shares will trade above, below or at their net asset value or the intraday value of the fund&#x2019;s holdings. During such periods, investors may incur significant losses if they sell shares.&lt;span style="font-weight:bold"&gt; &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;margin-bottom:0pt;font-size:9pt;font-family:arial;"&gt;The securities held by the fund may be traded in markets that close at a different time than the exchange on which the fund&#x2019;s shares are listed. 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 &lt;/div&gt;&lt;div style="margin-top:0pt;margin-bottom:0pt;font-size:9pt;font-family:arial;"&gt; exchange and the corresponding premium or discount to the shares&#x2019; net asset value may widen. &lt;/div&gt;</oef:RiskTextBlock>

Such shareholders may at times be considered to control the fund. In addition, a large number of shareholders may collectively purchase or redeem fund shares in large amounts rapidly or unexpectedly. Large shareholder transactions may adversely affect the fund&#x2019;s liquidity and net assets.

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.

Fixed income investments may be more susceptible to downgrades or defaults during economic downturns or other periods of economic stress. Interest rate risk is generally greater for longer-term fixed income securities, and credit risk is generally greater for below-investment-grade fixed income securities, which can be more sensitive to changes in markets, credit conditions, and interest rates, and may be considered speculative. &lt;/div&gt;</oef:RiskTextBlock>

There can be no assurance that an active trading market will develop or be maintained or that the market for fund shares will operate as intended, which could lead to the fund&#x2019;s shares trading at wider spreads and larger premiums and discounts to net asset value than other actively managed ETFs. As a result, it may cost investors more to trade fund shares than shares of other ETFs. There is no guarantee that the fund will be able to attract market makers and authorized participants. Market makers and authorized participants are not obligated to make a market in the fund&#x2019;s shares or to submit purchase and redemption orders for creation units. The market prices of the fund&#x2019;s shares are expected to fluctuate, in some cases materially, in response to changes in the fund&#x2019;s net asset value, the intraday value of the fund&#x2019;s holdings and supply and demand for the fund&#x2019;s shares. The Investment Manager cannot predict whether the fund&#x2019;s shares will trade above, below or at their net asset value or the intraday value of the fund&#x2019;s holdings. During such periods, investors may incur significant losses if they sell shares. &lt;/div&gt;&lt;div style="margin-top:6pt;margin-bottom:0pt;font-size:9pt;font-family:arial;"&gt;The securities held by the fund may be traded in markets that close at a different time than the exchange on which the fund&#x2019;s shares are listed. 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 &lt;/div&gt;&lt;div style="margin-top:0pt;margin-bottom:0pt;font-size:9pt;font-family:arial;"&gt; exchange and the corresponding premium or discount to the shares&#x2019; net asset value may widen. &lt;/div&gt;</oef:RiskTextBlock>

The fund may be an investment option for mutual funds that are managed by the Investment Manager and its affiliates as &#x201c;funds of funds.&#x201d; Additionally, other investors from time to time may make substantial investments in the fund. Such shareholders may at times be considered to control the fund. In addition, a large number of shareholders may collectively purchase or redeem fund shares in large amounts rapidly or unexpectedly. Large shareholder transactions may adversely affect the fund&#x2019;s liquidity and net assets. These redemptions may also adversely affect the fund&#x2019;s performance if the fund is forced to sell securities, which may also increase the fund&#x2019;s brokerage costs. &lt;/div&gt;</oef:RiskTextBlock>

The fund may have a limited number of financial institutions that act as authorized participants, none of which are obligated to engage in creation and/or redemption transactions. To the extent that those authorized participants do not engage in creation and redemption orders, there may be a significantly diminished trading market for fund shares or fund shares may trade at a discount (or premium) to net asset value and possibly face trading halts and/or de-listing. &lt;/div&gt;</oef:RiskTextBlock>

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.

The fund has the same investment goal and substantially similar strategies as the Predecessor Fund. However, the fund has a lower net expense ratio than each share class of the Predecessor Fund.
