Purchase and Sale of Fund Shares

Unlike conventional mutual funds, the Fund issues and redeems Shares on a continuous basis, at NAV, only in large blocks of Shares called “Creation Units.” Individual Shares of the Fund may only be purchased and sold on the secondary market through a broker-dealer. Since Shares of the Fund trade on securities exchanges in the secondary market at their market price rather than their NAV, the Fund’s Shares may trade at a price greater than (premium) or less than (discount) the Fund’s NAV. An investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase Shares of the Fund (bid) and the lowest price a

seller is willing to accept for Shares of the Fund (ask) when buying or selling Shares in the secondary market (the “bid-ask spread”). Recent information, including the Fund’s NAV, market price, premiums and discounts, and bid-ask spreads, is available online at newyorklifeinvestments.com/etf.

Tax Information

The Fund intends to distribute tax-exempt income. The Fund intends to meet certain U.S. federal tax requirements so that distributions of the tax-exempt interest it earns may be treated as exempt-interest dividends. A portion of the exempt-interest dividends may be subject to the alternative minimum tax on individuals and may have other tax consequences to certain shareholders. However, a portion of the Fund’s distributions may be subject to U.S. federal income tax, and may be taxed as ordinary income, qualified dividend income and/or capital gains, unless you are investing through a tax-deferred arrangement, such as a 401(k) plan or individual retirement account, in which case you may be subject to U.S. federal income tax upon withdrawal from such a tax-advantaged account. You should consult your tax advisor about your specific situation.

Financial Intermediary Compensation

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Advisor or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

Overview

The Trust is an investment company consisting of a number of separate investment portfolios (each, a “Fund” and together, the “Funds”) that are structured as exchange-traded funds (“ETFs”). Each share of a Fund represents an ownership interest in the securities and other instruments comprising a Fund’s portfolio. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on net asset value (“NAV”), shares of an ETF (such as the Funds) are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day, and may differ from a Fund’s NAV. IndexIQ Advisors LLC (the “Advisor”) is the investment advisor to each Fund and MacKay Shields LLC is the investment subadvisor to each Fund.

Each Fund has a distinct investment objective and policies. Except for the Rule 35d-1 policies discussed below, each of the policies described herein, including the investment objective of each Fund, constitutes a non-fundamental policy that may be changed by the Board of Trustees of the Trust (the “Board”) without shareholder approval. Certain fundamental policies of the Funds are set forth in the Funds’ Statement of Additional Information (the “SAI”) under “Investment Restrictions.” There can be no assurance that a Fund’s objective will be achieved.

Description of the Principal Strategies of the Funds

The Funds are actively managed ETFs and thus do not seek to replicate the performance of a specific index. Instead, each Fund uses an active investment strategy to meet its investment objective. The Subadvisor, subject to the oversight of the Advisor and Board, has discretion on a daily basis to manage each Fund’s portfolio in accordance with the Fund’s investment objective and investment policies.

In accordance with Rule 35d-1 under the Investment Company Act of 1940 (the “1940 Act”), the Funds, except for the IQ MacKay California Municipal Intermediate ETF, have each adopted a policy that each will, under normal circumstances, invest at least 80% of the value of its assets (net assets plus the amount of any borrowings for investment purposes) in debt securities whose interest is, in the opinion of bond counsel for the issuer at the time of issuance, exempt from federal income tax. The IQ MacKay California Municipal Intermediate ETF has adopted a policy that it will invest at least 80% of the value of its assets in municipal bonds whose interest is, in the opinion of bond counsel for the issuers at the time of issuance, exempt from federal and California income taxes. These policies are “fundamental,” which means that they may be changed only by the vote of a majority of a Fund’s outstanding shares as defined in the 1940 Act.

IQ MacKay Municipal Insured ETF has also adopted a policy that it will, under normal circumstances, invest at least 80% of its assets (net assets plus the amount of any borrowings for investment purposes) in insured Municipal Bonds. This policy is “non-fundamental,” which means that it may be changed without the vote of a majority of a Fund’s outstanding shares as defined in the 1940 Act. Each Fund has adopted a policy to provide the Fund’s shareholders with at least 60 days’ prior notice of any changes in the Fund’s non-fundamental investment policy with respect to investments of the type suggested by its name. A Fund may count investments in underlying funds toward various guideline tests (such as the 80% test required under Rule 35d-1 under the 1940 Act).

Each Fund’s investments are subject to certain requirements imposed by law and regulation, as well as a Fund’s investment strategy. These requirements are generally applied at the time a Fund invests its assets. If, subsequent to an investment by a Fund, this requirement is no longer met, the Fund’s future investments will be made in a manner that will bring the Fund into compliance with this requirement.

The Subadvisor generally gives consideration to ESG criteria when evaluating investment opportunities for the Funds, consistent with each Fund’s investment objective and Principal Investment Strategies. The application of ESG criteria may result in a Fund (i) having exposure to certain securities or industry sectors that are significantly different than the composition of the Fund’s benchmark; and (ii) performing differently than the Fund’s benchmark or other funds and strategies in the Fund’s peer group that do not take into account ESG criteria. In addition, sectors and securities of companies that meet the ESG criteria may shift into and out of favor depending on market and economic conditions. The consideration of ESG criteria may adversely affect a Fund’s performance. The Subadvisor may give consideration to ESG criteria including, but not limited to, climate change, sustainability, energy resources & management, job creation/employee relations, human rights, health and safety, transparency/disclosures, board expertise, audit practices, transparency and accountability.

Additional Investment Strategies

Borrowing Money

Each Fund may borrow money from a bank as permitted by the 1940 Act or the rules thereunder, or by the U.S. Securities and Exchange Commission (“SEC”) or other regulatory agency with authority over the Fund, but only for temporary or emergency purposes. The 1940 Act presently allows a fund to borrow from any bank (including pledging, mortgaging or hypothecating assets) in an amount up to 33 1/3% of its total assets (not including temporary borrowings not in excess of 5% of its total assets).

Temporary Defensive Positions

In times of unusual or adverse market, economic or political conditions or abnormal circumstances (such as large cash inflows or anticipated large redemptions), each Fund may, for temporary defensive purposes or for liquidity purposes (which may be for a prolonged period), invest outside the scope of its principal investment strategies. Under such conditions, a Fund may not invest in accordance with its investment objective or principal investment strategies and, as a result, there is no assurance that the Fund will achieve its investment objective. Under such conditions, each Fund may also invest without limit in cash, money market securities or other investments.

Securities Lending

A Fund may lend its portfolio securities. A securities lending program allows a Fund to receive a portion of the income generated by lending its securities and investing the respective collateral. In connection with such loans, a Fund receives liquid collateral equal to at least 102% (105% for foreign securities) of the value of the portfolio securities being lent. This collateral is marked to market on each trading day.

Description of the Principal Risks of the Funds

Investors in a Fund should carefully consider the risks of investing in the Fund as set forth in the Fund’s Summary Information section under “Principal Risks.” To the extent such risks apply, they are discussed hereunder in greater detail. See also the section on “Additional Risks” for other risk factors.

Alternative Minimum Tax Risk

The following risk applies to the IQ MacKay California Municipal Intermediate ETF

Although the interest received from municipal securities is generally exempt from federal income tax, the Fund may invest in municipal securities subject to the federal alternative minimum tax. Therefore, all or a portion of the Fund’s otherwise exempt interest, may be taxable to shareholders subject to (or result in an increased liability under) the federal alternative minimum tax.

Authorized Participant Concentration Risk

Only an Authorized Participant may engage in creation or redemption transactions directly with a Fund. Each Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation and/or redemption orders with a Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units, Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts and/or delisting. This risk may be heightened for ETFs that invest in non-U.S. securities because such securities often involve greater settlement and operational issues for Authorized Participants that may further limit the availability of Authorized Participants.

California State Specific Risk

The following risk applies to the IQ MacKay California Municipal Intermediate ETF

The Fund invests primarily in municipal bonds issued by or on behalf of the State of California and its political subdivisions, agencies, authorities and instrumentalities. As a result, the Fund is more exposed to the risks affecting issuers of California municipal bonds than is a municipal bond fund that invests more widely.

Most local government agencies within the State, particularly counties, continue to face budget constraints due to limited taxing powers, mandated expenditures for health, welfare and public safety and a weakened economy, among other factors. State and local governments are limited in their ability to levy and raise property taxes and other forms of taxes, fees or assessments, and in their ability to appropriate their tax revenues by a series of constitutional amendments enacted by voter initiatives since 1978. Individual local governments may also have local initiatives that affect their fiscal flexibility. The major sources of revenues for

35​

local government, property taxes and sales taxes, as well as fees based on real estate development, have all been adversely impacted by the economic recession. Unfunded pension and other post-retirement liabilities also weigh heavily upon the State as well as many local jurisdictions. While California’s economy is broad, it does have major concentrations in technology, aerospace and defense-related manufacturing, trade, entertainment, real estate and financial services, and may be sensitive to economic problems affecting those industries.

To the extent that California experiences economic problems generally, the risk of investing in bonds issued by the State and its political subdivisions, agencies, authorities and instrumentalities, including the risk of potential issuer default. There is a heightened risk that there could be an interruption in payments to bondholders in some cases. This possibility, along with the risk of a downgrade in the credit rating of the State’s general obligation debt, could result in a reduction in the market value of the bonds held by the Fund, which could adversely affect the Fund’s NAV or the distributions paid by the Fund. In addition, future California political and economic developments, constitutional amendments, legislative measures, executive orders, administrative regulations, litigation and voter initiatives could have an adverse effect on the debt obligations of California issuers.

Cash Transactions Risk

A Fund currently intends to effect creation and redemptions principally for cash, rather than principally for in-kind securities. As a result, investment in such a fund may be less tax efficient than investment in a conventional ETF. ETFs generally are able to make in-kind redemptions and avoid being taxed on gains on the distributed portfolio securities at the fund level. Because a Fund currently intends to effect redemptions principally for cash, the Fund may be required to sell portfolio securities in order to obtain the cash needed to distribute redemption proceeds. A Fund may recognize a capital gain on these sales that might not have been incurred if such Fund had made a redemption in-kind and this may decrease the tax efficiency of the Fund compared to ETFs that utilize an in-kind redemption process. Moreover, cash transactions may have to be carried out over several days if the securities market is relatively illiquid, and this may involve considerable brokerage fees and taxes. These brokerage fees and taxes, which will be higher than if a Fund sold and redeemed its Shares principally in-kind, will be passed on to those purchasing and redeeming Creation Units in the form of creation and redemption transaction fees. In addition, these factors may result in wider spreads between the bid and the offered prices of a Fund’s Shares than for ETFs that distribute portfolio securities in-kind.

Credit Risk

Credit risk is the risk that the issuer or guarantor of a debt instrument or the counterparty to a derivatives contract, repurchase agreement or loan of portfolio securities will be unable or unwilling to make its timely interest and/or principal payments or to otherwise honor its obligations. There are varying degrees of credit risk, depending on an issuer’s or counterparty’s financial condition and on the terms of an obligation, which may be reflected in the issuer’s or counterparty’s credit rating. There is the chance that a Fund’s portfolio holdings will have their credit ratings downgraded or will default (i.e., fail to make scheduled interest or principal payments), or that the market’s perception of an issuer’s or counterparty’s creditworthiness may worsen, potentially reducing a Fund’s income level or Share price. The value of an investment in a Fund may change quickly and without warning in response to issuer defaults, changes in the credit ratings of such Fund’s portfolio securities and/or perceptions related thereto.

Cyber Security Risk

The Funds are susceptible to operational risks through breaches in cyber security. A breach in cyber security refers to both intentional and unintentional events that may cause a Fund to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause a Fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. These risks typically are not covered by insurance. In general, cyber incidents can result from deliberate attacks or unintentional events. Cyber incidents include, but are not limited to, gaining unauthorized access to digital systems (e.g., through “hacking” or malicious software coding) for purposes of misappropriating assets or sensitive information, corrupting data or causing operational disruption. Cyber attacks may also be carried out in a manner that does not require gaining unauthorized access, such as causing denial-of-service attacks on websites (i.e., efforts to make network services unavailable to intended users). Cyber security failures by or breaches of the systems of security issuers, the Advisor, distributor and other service providers (including, but not limited to, sub-advisors, index providers, fund accountants, custodians, transfer agents and administrators), market makers, Authorized Participants or the issuers of securities in which a Fund invests, have the ability to cause disruptions and impact business operations, potentially resulting in financial losses, interference with a

36

Fund’s ability to calculate its NAV, disclosure of confidential trading information, impediments to trading, submission of erroneous trades or erroneous creation or redemption orders, the inability of a Fund or its service providers to transact business, violations of applicable privacy and other laws, regulatory fines and other penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs. Substantial costs may be incurred by a Fund in order to resolve or prevent cyber incidents in the future. While the Funds have established business continuity plans in the event of, and risk management systems to prevent, such cyber attacks, there are inherent limitations in such plans and systems, including the possibility that certain risks have not been identified and that prevention and remediation efforts will not be successful. Furthermore, the Funds cannot control the cyber security plans and systems put in place by service providers to the Funds, issuers in which the Funds invest, Authorized Participants or market makers. There is no guarantee that such preventative efforts will succeed, and the Funds and their shareholders could be negatively impacted as a result.

Debt Securities Risk

The risks of investing in debt securities include (without limitation): (i) credit risk, e.g., the issuer or guarantor of a debt security may be unable or unwilling (or be perceived as unable or unwilling) to make timely principal and/or interest payments or otherwise honor its obligations; (ii) interest rate risk, e.g., when interest rates go up, the value of a debt security generally goes down, and when interest rates go down, the value of a debt security generally goes up; (iii) liquidity risk and valuation risk, e.g., debt securities generally do not trade on a securities exchange, making them generally less liquid and more difficult to value than common stock; (iv) call risk and income risk, e.g., during a period of falling interest rates, the issuer may redeem a security by repaying it early, which may reduce a Fund’s income if the proceeds are reinvested at lower interest rates; and (v) extension risk, e.g., if interest rates rise, repayments of debt securities may occur more slowly than anticipated by the market, which may drive the prices of these securities down because their interest rates are lower than the current interest rate and the securities remain outstanding longer. Debt securities most frequently trade in institutional round lot size transactions. If the Fund purchases bonds in amounts less than the institutional round lot size, which are frequently referred to as “odd” lots, the odd lot size positions may have more price volatility than institutional round lot size positions. The Fund uses a third-party pricing service to value bond holdings and the pricing service values bonds assuming orderly transactions of an institutional round lot size.

Focused Investment Risk

To the extent that a Fund invests a large percentage of its assets in a single asset class or the securities of issuers within the same country, group of countries, region, industry, group of industries or sector, an adverse economic, market, political or regulatory development may affect the value of the Fund’s investments more than if the Fund were more broadly diversified. Different asset classes, countries, groups of countries, regions, industries, groups of industries or sectors tend to go through cycles of outperformance and underperformance in comparison to each other and to the general financial markets.

High-Yield Municipal Bond Risk

The following risk applies to the IQ MacKay California Municipal Intermediate ETF

High-yield or non-investment grade municipal bonds (commonly referred to as “junk bonds”) may be subject to increased liquidity risk as compared to other high-yield debt securities. There may be little or no active trading market for certain high-yield municipal bonds, which may make it difficult for the Fund to sell such bonds at or near their perceived value. In such cases, the value of a high-yield municipal bond may decline dramatically, even during periods of declining interest rates. The high-yield municipal bonds in which the Fund intends to invest may be more likely to pay interest that is includable in taxable income for purposes of the federal alternative minimum tax than other municipal bonds.

Income Risk

A Fund’s income may decline when interest rates fall or if there are defaults in its portfolio. This decline can occur because a Fund may subsequently invest in lower-yielding securities when securities in its portfolio mature or the Fund otherwise needs to purchase additional securities.

Interest Rate Risk

An increase in interest rates may cause the value of certain fixed income securities held by a Fund to decline. Many factors can cause interest rates to rise, such as central bank monetary policies, inflation rates, general economic conditions and expectations about the foregoing. Fixed income securities with longer durations tend to be more sensitive to changes in interest rates, making them more volatile than securities with shorter

37​

durations or floating or adjustable interest rates. Duration is a measure used to determine the sensitivity of a fixed income security’s price to changes in interest rates. For example, the value of a fixed income security with a duration of three years would be expected to decrease by 3% for every 1% increase in interest rates. The negative impact on a Fund from potential interest rate increases could be swift and significant, including falling market values, increased redemptions and reduced liquidity. Substantial shareholder redemptions may worsen this impact. An increase in interest rates could also cause principal payments on a fixed income security to be repaid at a slower rate than expected. This risk is particularly prevalent for a callable debt security where an increase in interest rates could cause the issuer of that security to not redeem the security as anticipated on the call date, effectively lengthening the security’s expected maturity, in turn making that security more vulnerable to interest rate risk and reducing its market value. A Fund may be subject to a greater risk of rising interest rates than would normally be the case due to the current period of historically low rates and the effect of potential government fiscal policy initiatives and resulting market reaction to those initiatives.

When interest rates rise, certain obligations will be paid off by the issuer (or other obligated party) more slowly than anticipated, causing the value of these securities to fall. Rising interest rates tend to extend the duration of fixed income securities, making their market value more sensitive to changes in interest rates. As a result, in a period of rising interest rates, securities may exhibit additional volatility and may lose value. The value of securities with longer maturities generally changes more in response to changes in interest rates than does the value of securities with shorter maturities. Extension risk is particularly prevalent for a callable fixed income security where an increase in interest rates could result in the issuer of that security choosing not to redeem the security as anticipated on the security’s call date. Such a decision by the issuer could have the effect of lengthening the security’s expected maturity, making it more vulnerable to interest rate risk and reducing its market value.

Some securities may be redeemed at the option of the issuer, or “called,” before their stated maturity date. In general, an issuer will call its debt securities if they can be refinanced by issuing new debt securities which bear a lower interest rate. A Fund is subject to the possibility that during periods of falling interest rates an issuer will call its high-yielding debt securities. A Fund may then be forced to invest the unanticipated proceeds in securities with lower yields, resulting in a decline in the Fund’s income, or in securities with greater risks or with other less favorable features. Such redemptions and subsequent reinvestments would also increase a Fund’s portfolio turnover. If a called debt security was purchased by a Fund at a premium, the value of the premium may be lost in the event of a redemption.

The terms of floating rate notes and other instruments may be tied to the London Interbank Offered Rate (“LIBOR”), which functions as a reference rate or benchmark. The discontinuation of LIBOR may cause increased volatility and illiquidity in the markets for instruments with terms tied to LIBOR or other adverse consequences, such as decreased yields and reduction in value, for these instruments. These events may adversely affect the Fund and its investments in such instruments. For more information on the risks associated with the discontinuation and transition of LIBOR, please see “LIBOR Replacement Risk.”

Issuer Risk

The performance of a Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures, credit deterioration of the issuer or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline. An issuer may also be subject to risks associated with the countries, states and regions in which the issuer resides, invests, sells products or otherwise conducts operations.

Liquidity Risk

Liquidity risk exists when particular investments are difficult to purchase or sell. To the extent the Fund invests in illiquid securities or securities that become less liquid, such investments may have a negative effect on the returns of the Fund because the Fund may be unable to sell the illiquid securities at an advantageous time or price. Securities with substantial market and/or credit risk may be especially susceptible to liquidity risk. Liquidity risk may be the result of, among other things, an investment being subject to restrictions on resale, trading over-the-counter or in limited volume, or lacking an active trading market. Liquid investments may become illiquid or less liquid after purchase by the Fund, particularly during periods of market turmoil or economic uncertainty. Illiquid and relatively less liquid investments may be harder to value, especially in changing

38

markets. If the Fund is forced to sell underlying investments at reduced prices or under unfavorable conditions to meet redemption requests or for other cash needs, the Fund may suffer a loss. This may be magnified in a rising interest rate environment or under other circumstances where redemptions from the Fund may be higher than normal. It may also be the case that other market participants may be attempting to liquidate similar holdings at the same time as the Fund, causing increased supply in the market and contributing to liquidity risk and downward pricing pressure. There can be no assurance that a security that is deemed to be liquid when purchased will continue to be liquid or as long as it is held by the Fund.

Market Risk

The value of a Fund’s investments may fluctuate and/or decline because of changes in the markets in which the Fund invests, which could cause the Fund to underperform other funds with similar investment objectives and strategies. Security markets are volatile and may decline significantly in response to adverse issuer, regulatory, political, or economic developments. Different sectors of the market and different security types may react differently to such developments. Changes in these markets may be rapid and unpredictable. Fluctuations in the markets generally or in a specific industry or sector may impact the securities in which a Fund invests. From time to time, markets may experience periods of stress for potentially prolonged periods that may result in: (i) increased market volatility; (ii) reduced market liquidity; and (iii) increased redemptions of Fund shares. Such conditions may add significantly to the risk of volatility in the net asset value of a Fund’s shares and the market prices at which shares of a Fund trade on a securities exchange. During periods of market stress shares of a Fund may also experience significantly wider “bid/ask” spreads and premiums and discounts between a Fund’s net asset value and market price.

Market changes may impact equity and fixed income securities in different and, at times, conflicting manners. A Fund potentially will be prevented from executing investment decisions at an advantageous time or price as a result of any domestic or global market disruptions, particularly disruptions causing heightened market volatility and reduced market liquidity, as well as increased or changing regulations or market closures. Thus, investments that the Subadvisor believes represent an attractive opportunity or in which a Fund seeks to obtain exposure may be unavailable entirely or in the specific quantities sought by the Subadvisor and the Fund may need to obtain the exposure through less advantageous or indirect investments or forgo the investment at the time. Securities and investments held by a Fund may be susceptible to declines in value, including declines in value that are not believed to be representative of the issuer’s value or fundamentals, due to investor reactions to such events.

Political and diplomatic events within the United States and abroad, such as the U.S. budget and deficit reduction plans, protectionist measures, trade tensions central bank policy and government intervention in the economy, has in the past resulted, and may in the future result, in developments that present additional risks to a Fund’s investments and operations. Geopolitical and other events, such as war, acts of terrorism, natural disasters, the spread of infectious illnesses, epidemics and pandemics, environmental and other public health issues, recessions or other events, and governments’ reactions to such events, may lead to increased market volatility and instability in world economies and markets generally and may have adverse effects on the performance of a Fund and its investments. Additional and/or prolonged geopolitical or other events may affect investor and consumer confidence and may adversely impact financial markets and the broader economy, perhaps suddenly and to a significant degree. Any such market, economic and other disruptions could also prevent a Fund from executing its investment strategies and processes in a timely manner.

An investment in a Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. When you sell your Shares, they could be worth less than what you paid for them.

Market Disruption Risk and Recent Market Events

Geopolitical and other events, including war, terrorism, economic uncertainty, trade disputes, public health crises and related geopolitical events have led, and in the future may lead, to disruptions in the US and world economies and markets, which may increase financial market volatility and have significant adverse direct or indirect effects on a Fund and its investments. Market disruptions could cause a Fund to lose money, experience significant redemptions and encounter operational difficulties. Although multiple asset classes may be affected by a market disruption, the duration and effects may not be the same for all types of assets. Recent market disruption events include the pandemic spread of the novel coronavirus known as COVID-19, and the significant restrictions, market volatility, decreased economic and other activity and increased government activity that it has caused. Specifically, COVID-19 has led to significant death and morbidity, and

39​

concerns about its further spread have resulted in the closing of schools and non-essential businesses, cancellations, shelter-in-place orders, lower consumer spending in certain sectors, social distancing, bans on large social gatherings and travel, quarantines, government economic stimulus measures, reduced productivity, rapid increases in unemployment, increased demand for and strain on government and medical resources, border closings and global trade and supply chain interruptions, among others. The full effects, duration and costs of the COVID-19 pandemic are impossible to predict, and the circumstances surrounding the COVID-19 pandemic will continue to evolve. The pandemic may affect certain countries, industries, economic sectors, companies and investment products more than others, may exacerbate existing economic, political, or social tensions and may increase the probability of an economic recession or depression. A Fund and its investments may be adversely affected by the effects of the COVID-19 pandemic, and a prolonged pandemic may result in a Fund and its service providers experiencing operational difficulties in coordinating a remote workforce and implementing their business continuity plans, among others.

Money Market/Short-Term Securities Risk

To the extent that a Fund invests in money market or short-term securities, the Fund may be subject to certain risks associated with such investments. An investment in a money market fund or short-term securities is not a bank deposit and is not insured or guaranteed by any bank, the Federal Deposit Insurance Corporation or any other government agency. It is possible for a Fund to lose money by investing in money market funds. A money market fund may not achieve its investment objective. Changes in government regulations may affect the value of an investment in a money market fund.

Municipal Bond Market Liquidity Risk

Inventories of Municipal Bonds held by brokers and dealers may decrease, lessening their ability to make a market in these securities. Any reduction in market-making capacity has the potential to decrease a Fund’s ability to buy or sell Municipal Bonds and increase price volatility and trading costs, particularly during periods of economic or market stress. In addition, federal banking regulations may cause certain dealers to reduce their inventories of Municipal Bonds, which may further decrease a Fund’s ability to buy or sell Municipal Bonds. As a result, a Fund may be forced to accept a lower price to sell a municipal security, to sell other securities to raise cash, or to give up an investment opportunity, any of which could have a negative effect on performance. The market for unrated municipal securities may be less liquid than the market for rated Municipal Bonds of comparable quality. Decreased liquidity may negatively affect a Fund’s ability to mitigate risk and meet redemptions. Also, less public information is typically available about unrated Municipal Bonds or their issuers, which can affect the liquidity of the market.

Municipal Bond Risk

The values of Municipal Bonds may be adversely affected by local political and economic conditions and developments. Adverse conditions in an industry significant to a local economy could have a correspondingly adverse effect on the financial condition of local issuers. Other factors that could affect Municipal Bonds include a change in the local, state, or national economy, demographic factors, ecological or environmental concerns, statutory limitations on the issuer’s ability to increase taxes, and other developments generally affecting the revenue of issuers (for example, legislation or court decisions reducing state aid to local governments or mandating additional services). This risk would be heightened to the extent that a Fund invests a substantial portion of its assets in bonds issued pursuant to similar projects (such as those relating to the education, health care, housing, transportation, or utilities industries), in industrial development bonds, or in particular types of municipal securities (such as general obligation bonds, private activity bonds or moral obligation bonds) that are particularly exposed to specific types of adverse economic, business or political events. Changes in a municipality’s financial health may also make it difficult for the municipality to make interest and principal payments when due. The values of Municipal Bonds that depend on a specific revenue source to fund their payment obligations may fluctuate as a result of actual or anticipated changes in the cash flows generated by the revenue source or changes in the priority of the municipal obligation to receive the cash flows generated by the revenue source. Under some circumstances, municipal securities might not pay interest unless the state legislature or municipality authorizes money for that purpose. Municipal Bonds may be more susceptible to downgrades or defaults during recessions or similar periods of economic stress. In addition, since some municipal securities may be secured or guaranteed by banks and other institutions, the risk to a Fund could increase if the banking or financials sector suffers an economic downturn and/or if the credit ratings of the institutions issuing the guarantee are downgraded or at risk of being downgraded by a national rating organization. Such a downward revision or risk of being downgraded may have an adverse effect on the market prices of the bonds and thus the value of a Fund’s investments. In addition to being downgraded, an

40

insolvent municipality may file for bankruptcy. The reorganization of a municipality’s debts may significantly affect the rights of creditors and the value of the securities issued by the municipality and the value of a Fund’s investments. In addition, income from Municipal Bonds held by a Fund could be declared taxable because of, among other things, unfavorable changes in tax laws, adverse interpretations by the Internal Revenue Service or state tax authorities, or noncompliant conduct of an issuer or other obligated party. Loss of tax-exempt status may cause interest received and distributed to shareholders by a Fund to be taxable and may result in a significant decline in the values of such Municipal Bonds. There are various different types of Municipal Bonds, each with its own unique risk profile. Some of these risks include:

•

General Obligation Bonds Risk—timely payments depend on the issuer’s credit quality, ability to raise tax revenues and ability to maintain an adequate tax base;

​

•

Revenue Bonds (including Industrial Development Bonds) Risk—timely payments depend on the money earned by the particular facility or class of facilities, or the amount of revenues derived from another source, and may be negatively impacted by the general credit of the user of the facility;

​

•

Private Activity Bonds Risk—municipalities and other public authorities issue private activity bonds to finance development of industrial facilities for use by a private enterprise, which is solely responsible for paying the principal and interest on the bonds, and payment under these bonds depends on the private enterprise’s ability to do so;

​

•

Moral Obligation Bonds Risk—moral obligation bonds are generally issued by special purpose public authorities of a state or municipality. If the issuer is unable to meet its obligations, repayment of these bonds becomes a moral commitment, but not a legal obligation, of the state or municipality;

​

•

Municipal Notes Risk—municipal notes are shorter-term municipal debt obligations that pay interest that is, in the opinion of bond counsel for the issuer at the time of issuance, generally excludable from gross income for federal income tax purposes (except that the interest may be includable in taxable income for purposes of the federal alternative minimum tax) and that have a maturity that is generally one year or less. If there is a shortfall in the anticipated proceeds, the notes may not be fully repaid and the Fund may lose money; and

​

•

Municipal Lease Obligations Risk—in a municipal lease obligation, the issuer agrees to make payments when due on the lease obligation. Although the issuer does not pledge its unlimited taxing power for payment of the lease obligation, the lease obligation is secured by the leased property.

​

Municipal Bond Valuation Risk

The Municipal Bonds in which a Fund invests are typically valued by a pricing service utilizing a range of market-based inputs and assumptions, including readily available market quotations obtained from broker-dealers making markets in such securities, cash flows and transactions for comparable instruments. There is no assurance that a Fund will be able to sell a portfolio security at the price established by the pricing service, which could result in a loss to a Fund.

Municipal Insurance Risk

The following risk applies to the IQ MacKay Municipal Insured ETF and IQ MacKay California Municipal Intermediate ETF

A Fund’s investments may include investments in insured Municipal Bonds. Municipal security insurance does not guarantee the value either of individual municipal securities or of Shares of the Fund. In addition, a municipal security insurance policy generally will not cover: (i) repayment of a municipal security before maturity (redemption), (ii) prepayment or payment of an acceleration premium (except for a mandatory sinking fund redemption) or any other provision of a bond indenture that advances the maturity of the bond or (iii) non-payment of principal or interest caused by negligence or bankruptcy of the paying agent. A mandatory sinking fund redemption may be a provision of a municipal security issue whereby part of the municipal security issue may be retired before maturity. Market conditions or changes to ratings criteria could adversely impact the ratings of Municipal Bond insurance companies. Downgrades and withdrawal of ratings from Municipal Bond insurers have substantially limited the availability of insurance sought by Municipal Bond issuers, thereby reducing the supply of insured Municipal Bonds that meet the Fund’s investment guidelines or the ability of a Fund to purchase insurance on Municipal Bonds held by the Fund. A rating downgrade of a Municipal Bond insurer could negatively impact the market value of insured Municipal Bonds held by a Fund. If the insurer of a defaulted Municipal Bond were to become unable or unwilling to pay the principal or interest

41​

on the defaulted Municipal Bond, a Fund would incur losses. Because of the consolidation among insurers of municipal securities, to the extent that a Fund invests in insured Municipal Bonds, it is subject to the risk that credit risk may be concentrated among fewer insurers and the risk that events involving one or more insurers could have a significant adverse effect on the value of the securities insured by an insurer and on the municipal markets as a whole.

New Fund Risk

The following risk applies to the IQ MacKay Municipal Short Duration ETF and IQ MacKay California Municipal Intermediate ETF

As a new fund, there can be no assurance that a Fund will grow to or maintain an economically viable size, in which case it could ultimately liquidate. Like other new funds, large inflows and outflows may impact a Fund’s market exposure for limited periods of time. This impact may be positive or negative, depending on the direction of market movement during the period affected. An Authorized Participant, the Advisor or an affiliate of the Advisor may invest in a Fund and hold its investments for a specific period of time in order to facilitate commencement of the Fund’s operations or for the Fund to achieve size or scale. There can be no assurance that any such entity would not redeem its investment or that the size of a Fund would be maintained at such levels which could negatively impact the Fund.

Operational Risk

Each Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund, Advisor and Subadvisor seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.

Portfolio Management Risk

Each Fund is subject to portfolio management risk because it is an actively managed portfolio. In managing a Fund’s investment portfolio, the portfolio managers will apply investment techniques and risk analyses that may not produce the desired result. There can be no guarantee that the Fund will meet its investment objective(s). In addition, a Fund may not achieve its investment objective if the portfolio managers take temporary positions in response to unusual or adverse market, economic or political conditions, or other unusual or abnormal circumstances. The Subadvisor may give consideration to certain ESG criteria when evaluating an investment opportunity. The application of ESG criteria may result in the Fund (i) having exposure to certain securities or industry sectors that are significantly different than the composition of the Fund’s benchmark; and (ii) performing differently than other funds and strategies in its peer group that do not take into account ESG criteria or the Fund’s benchmark. The investments selected by a Fund’s portfolio managers may underperform the market or other investments.

Private Placement and Restricted Securities Risk

The following risk applies to the IQ MacKay California Municipal Intermediate ETF

The Fund may invest in privately issued securities, including those which may be resold only in accordance with Rule 144A under the Securities Act of 1933, as amended. Securities acquired in a private placement generally are subject to strict restrictions on resale, and there may be no market or a limited market for the resale of such securities. Therefore, the Fund may be unable to dispose of such securities when it desires to do so or at the most favorable price. This potential lack of liquidity also may make it more difficult to accurately value these securities.

Secondary Market Trading Risk

Although each Fund’s Shares are listed for trading on one or more securities exchanges, there can be no assurance that an active trading market for such Shares will develop or be maintained by market makers or Authorized Participants. The trading of Shares on securities exchanges is subject to the risk of irregular trading activity. Additionally, market makers are under no obligation to make a market in a Fund’s Shares and Authorized Participants are not obligated to submit purchase or redemption orders for Creation Units. In the event market makers cease making a market in a Fund’s Shares or Authorized Participants stop submitting purchase or redemption orders for Creation Units, such Fund’s Shares may trade at a larger premium or discount to its NAV. Wide bid-ask spreads and large premiums or discounts to NAV are likely to lead to an investor buying his or her shares at a market price that is more than their value, and selling those shares at a market price that is less than their value.

42

Buying or selling Shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling Shares through a broker, you will likely incur a brokerage commission and other charges. In addition, you may incur the cost of the “spread”—the difference between what investors are willing to pay for Shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). The spread, which varies over time for Shares based on trading volume and market liquidity, is generally narrower if the Fund has more trading volume and market liquidity and wider if the Fund has less trading volume and market liquidity. The risk of wide bid and ask spreads may be especially pronounced for smaller funds. In addition, increased market volatility may cause wider spreads. There may also be regulatory and other charges that are incurred as a result of trading activity. Because of the costs inherent in buying or selling Shares, frequent trading may detract significantly from investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments through a brokerage account.

Securities exchanges have requirements that must be met in order for Shares to be listed. There can be no assurance that the requirements of an exchange necessary to maintain the listing of Shares will continue to be met. This risk is particularly acute for funds that fail to attract a large number of shareholders. Pursuant to an exchange’s “circuit breaker” rules, trading in a Fund’s Shares may be halted due to extraordinary market volatility.

Trading Price Risk

Shares of a Fund trade on securities exchanges at prices at, above or below the Fund’s most recent NAV. The NAV of a Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings. The trading price of a Fund’s Shares fluctuates continuously throughout trading hours based on both market supply of and demand for Shares and the Fund’s NAV. As a result, the trading prices of a Fund’s Shares may deviate significantly from NAV during periods of market volatility. The market price of a Fund’s Shares during the trading day, like the price of any exchange-traded security, includes a “bid/ask” spread charged by the exchange specialist, market makers or other participants that trade the Shares. In times of severe market disruption, the bid/ask spread can increase significantly. At those times, Shares are most likely to be traded at a discount to NAV, and the discount is likely to be greatest when the price of Shares is falling fastest, which may be the time that an investor most wants to sell their Shares. Although it is generally expected that the market price of a Fund’s Shares will approximate the Fund’s NAV, there may be times when the market price and the NAV vary significantly. Thus, an investor may pay more than NAV when purchasing Shares and receive less than NAV when selling Shares. While the creation/redemption feature is designed to make it more likely that a Fund’s Shares normally will trade on securities exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund’s NAV due to timing reasons, supply and demand imbalances and other factors. In addition, disruptions to creations and redemptions, including disruptions at market makers, Authorized Participants, or other market participants, and during periods of significant market volatility, may result in trading prices for Shares of a Fund that differ significantly from its NAV. Authorized Participants may be less willing to create or redeem Shares if there is a lack of an active market for such Shares or its underlying investments, which may contribute to the Fund’s Shares trading at a premium or discount to NAV. Additionally, similar to shares of other issuers listed on a securities exchange, a Fund’s Shares may be sold short and are therefore subject to the risk of increased volatility and price decreases associated with being sold short. Any of these factors, among others, may lead to a Fund’s Shares trading at a premium or discount to NAV.

Variable and Floating Rate Instruments Risk

The following risk applies to the IQ MacKay California Municipal Intermediate ETF

Variable and floating rate instruments include debt securities issued by corporate and governmental entities, bank loans, mortgage-backed securities and asset-backed securities, preferred equity securities and derivative variable rate securities, such as inverse floaters. Variable and floating rate instruments are structured so that the instrument’s coupon rate fluctuates based upon the level of a reference rate. Most commonly, the coupon rate of a variable or floating rate instrument is set at the level of a widely followed interest rate, plus a fixed spread. As a result, the coupon on a variable or floating rate instrument will generally decline in a falling interest rate environment, causing the Fund to experience a reduction in the income it receives from the instrument. A variable or floating rate instrument’s coupon rate resets periodically according to its terms. Consequently, in a rising interest rate environment, variable and floating rate instruments with coupon rates that reset infrequently may lag behind the changes in market interest rates. Variable and floating rate instruments may also contain terms that impose a maximum coupon rate the issuer will pay, regardless of the level of the reference rate. The

43​

coupon rate of many variable and floating rate instruments is set based upon LIBOR. In 2017, the head of the United Kingdom’s Financial Conduct Authority announced a desire to phase out the use of LIBOR by the end of 2021. However, subsequent announcements by the Financial Conduct Authority, LIBOR administrators, and other regulators indicate that it is possible that the most widely used LIBOR rates may continue until mid-2023. There remains uncertainty regarding the future utilization of LIBOR and the nature of any replacement rate. The potential effect of a transition away from LIBOR cannot yet be determined but may result in disruption to the markets for debt securities and instruments and decreased demand or liquidity for debt securities and instruments that reference LIBOR or new replacement rates.

Additional Risks

Large Investments Risk

From time to time, a Fund may receive large purchase or redemption orders from affiliated or unaffiliated funds or other investors. In addition, any third-party investor, investment advisor affiliate, authorized participant, lead market maker or other entity may make a large investment in a Fund and hold its investment for any number of reasons, including to facilitate such Fund’s commencement of operations or to facilitate the Fund’s achieving a specified size or scale. There can be no assurance that any large shareholder would not sell or redeem its investment at any given time, either in a single transaction or over time. These large transactions, and particularly redemptions, could have adverse effects on a Fund, including: (i) negative impacts to performance if the Fund were required to sell securities, invest cash or hold significant cash at times when it otherwise would not do so; (ii) wider price spreads or greater premiums/discounts that could materialize as a result of lower secondary market volume of shares; and (iii) negative federal income tax consequences if this activity accelerated the realization of capital gains.

LIBOR Replacement Risk

The terms of floating rate loans, financings or other transactions in the U.S. and globally have been historically tied to LIBOR, which functions as a reference rate or benchmark for various commercial and financial contracts. LIBOR may be a significant factor in determining payment obligations under derivatives transactions, the cost of financing of a Fund’s investments or the value or return on certain other Fund investments. As a result, LIBOR may be relevant to, and directly affect, a Fund’s performance. The Financial Conduct Authority, the United Kingdom’s financial regulatory body and regulator of LIBOR, announced that after 2021 it will cease its active encouragement of banks to provide the quotations needed to sustain LIBOR due to the absence of an active market for interbank unsecured lending and other reasons. However, subsequent announcements by the Financial Conduct Authority, LIBOR administrators, and other regulators indicate that it is possible that the most widely used LIBOR rates may continue until mid-2023. As a result, it is anticipated that LIBOR will be discontinued or will no longer be sufficiently robust to be representative of its underlying market around that time. Various financial industry groups have begun planning for that transition and certain regulators and industry groups have taken actions to establish alternative reference rates (e.g., the Secured Overnight Financing Rate, which measures the cost of overnight borrowings through repurchase agreement transactions collateralized with U.S. Treasury securities and is intended to replace U.S. dollar LIBOR with certain adjustments). However, there are challenges to converting certain contracts and transactions to a new benchmark and neither the full effects of the transition process nor its ultimate outcome is known.

The transition process might lead to increased volatility and illiquidity in markets for instruments with terms tied to LIBOR. It could also lead to a reduction in the interest rates on, and the value of, some LIBOR-based investments and reduce the effectiveness of hedges mitigating risk in connection with LIBOR-based investments. Although some LIBOR-based instruments may contemplate a scenario where LIBOR is no longer available by providing for an alternative rate-setting methodology and/or increased costs for certain LIBOR-related instruments or financing transactions, others may not have such provisions and there may be significant uncertainty regarding the effectiveness of any such alternative methodologies. Instruments that include robust fallback provisions to facilitate the transition from LIBOR to an alternative reference rate may also include adjustments that do not adequately compensate the holder for the different characteristics of the alternative reference rate. The result may be that the fallback provision results in a value transfer from one party to the instrument to the counterparty. Additionally, because such provisions may differ across instruments (e.g., hedges versus cash positions hedged), LIBOR’s cessation may give rise to basis risk and render hedges less effective. As the usefulness of LIBOR as a benchmark could deteriorate during the transition period, these effects and related adverse conditions could occur prior to the end of 2021 with respect to certain LIBOR tenors or mid-2023 for the remaining LIBOR tenors. There also remains uncertainty and risk regarding the willingness and ability of issuers to

44

include enhanced provisions in new and existing contracts or instruments, notwithstanding significant efforts by the industry to develop robust LIBOR replacement clauses. The effect of any changes to, or discontinuation of, LIBOR on a Fund will vary depending, among other things, on (1) existing fallback or termination provisions in individual contracts and the possible renegotiation of existing contracts and (2) whether, how, and when industry participants develop and adopt new reference rates and fallbacks for both legacy and new products and instruments. A Fund’s investments may also be tied to other interbank offered rates and currencies, which also will likely face similar issues. In many cases, in the event that an instrument falls back to an alternative reference rate, including the Secured Overnight Financing Rate, the alternative reference rate will not perform the same as LIBOR because the alternative reference rate does not include a credit sensitive component in the calculation of the rate. Alternative reference rates generally reflect the performance of the market for U.S. treasury securities, which are secured by the U.S. treasury, and not the inter-bank lending markets. In the event of a credit crisis, floating rate instruments using certain alternative reference rates could therefore perform differently than those instruments using a rate indexed to the inter-bank lending market.

Various pending legislation, including in the U.S. Congress and the New York state legislature, may affect the transition of LIBOR-based instruments as well by permitting trustees and calculation agents to transition instruments with no LIBOR transition language to an alternative reference rate selected by such agents. Those legislative proposals include safe harbors from liability, which may limit the recourse a Fund may have if the alternative reference rate does not fully compensate the Fund for the transition of an instrument from LIBOR. It is uncertain whether such legislative proposals will be signed into law.

These developments could negatively impact financial markets in general and present heightened risks, including with respect to a Fund’s investments. As a result of this uncertainty and developments relating to the transition process, a Fund and its investments may be adversely affected.

Underinvestment Risk

If certain aggregate ownership thresholds are reached either through the actions of the Advisor and its affiliates or a Fund, or as a result of third-party transactions, the ability of the Advisor on behalf of clients (including a Fund) to purchase or dispose of investments, or exercise rights or undertake business transactions, may be restricted by regulation or otherwise impaired. The capacity of a Fund to make investments in certain securities may be affected by the relevant limits, and such limitations may have adverse effects on the liquidity and performance of a Fund’s portfolio holdings.

U.S. Tax Risk

To qualify for the favorable U.S. federal income tax treatment accorded to regulated investment companies, a Fund must satisfy certain income, asset diversification and distribution requirements. If for any taxable year, a Fund does not qualify as a regulated investment company, all of its taxable income (including its net capital gain) for that year would be subject to tax at regular corporate rates without any deduction for distributions to its shareholders, and the Fund’s distributions, including distributions of tax-exempt income, would be taxable to its shareholders as dividend income to the extent of a Fund’s current and accumulated earnings and profits. To the extent a Fund engages in derivatives transactions, the tax treatment such derivatives transactions is unclear for purposes of determining a Fund’s tax status. To the extent a Fund engages in transactions in financial instruments, including, but not limited to, options, futures contracts, hedging transactions, forward contracts and swap contracts, the Fund will be subject to special tax rules (which may include mark-to-market, constructive sale, wash sale and short sale rules), the effect of which may be to accelerate income to the Fund, defer losses to the Fund, cause adjustments in the holding periods of the Fund’s securities, convert long-term capital gains into short-term capital gains or convert short-term capital losses into long-term capital losses. These rules could, therefore, affect the amount, timing and character of distributions to a Fund’s shareholders. A Fund’s use of such transactions may result in the Fund realizing more short-term capital gains and ordinary income, in each case subject to U.S. federal income tax at higher ordinary income tax rates, than it would if it did not engage in such transactions.

Buying and Selling Shares in the Secondary Market

Most investors will buy and sell Shares of each Fund in Secondary Market transactions through brokers. Shares of each Fund will be listed for trading on the Secondary Market on the NYSE Arca. Shares can be bought and sold throughout the trading day like other publicly-traded shares. Unless imposed by your broker or dealer, there is no minimum dollar amount you must invest and no minimum number of Shares you must buy in the Secondary Market. When buying or selling Shares through a broker, you will incur customary brokerage commissions and

45​

charges, and you may pay some or all of the spread between the bid and the offered price in the Secondary Market on each leg of a round trip (purchase and sale) transaction. In addition, because transactions in the Secondary Market occur at market prices, you may pay more than NAV when you buy Shares and receive less than NAV when you sell those Shares.

Share prices are reported in dollars and cents per Share. For information about buying and selling Shares in the Secondary Market, please contact your broker or dealer.

Book Entry

Shares of each Fund are held in book-entry form and no stock certificates are issued. DTC, through its nominee Cede & Co., is the record owner of all outstanding Shares.

Investors owning Shares are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for all Shares. Participants in DTC include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of Shares, you are not entitled to receive physical delivery of stock certificates or to have Shares registered in your name, and you are not considered a registered owner of Shares. Therefore, to exercise any right as an owner of Shares, you must rely upon the procedures of DTC and its participants.

These procedures are the same as those that apply to any securities that you hold in book entry or “street name” form for any publicly-traded company. Specifically, in the case of a shareholder meeting of a Fund, DTC assigns applicable Cede & Co. voting rights to its participants that have Shares credited to their accounts on the record date, issues an omnibus proxy and forwards the omnibus proxy to the Fund. The omnibus proxy transfers the voting authority from Cede & Co. to the DTC participant. This gives the DTC participant through whom you own Shares (namely, your broker, dealer, bank, trust company or other nominee) authority to vote the shares, and, in turn, the DTC participant is obligated to follow the voting instructions you provide.

Management

The Board is responsible for the general supervision of the Funds. The Board appoints officers who are responsible for the day-to-day operations of the Funds.

Investment Advisor

The Advisor has been registered as an investment advisor with the SEC since August 2007 and is a wholly-owned indirect subsidiary of New York Life Investment Management Holdings LLC. The Advisor’s principal office is located at 51 Madison Avenue, New York, New York 10010. As of June 30, 2022, the Advisor had approximately $8.2 billion in assets under management.

The Advisor has overall responsibility for the general management and administration of the Trust. The Advisor provides an investment program for the Funds. The Advisor has delegated certain advisory duties with regard to the Funds (including management of all of the Fund’s assets) to the Subadvisor. The Advisor has also arranged for custody, fund administration, transfer agency and all other non-distribution related services necessary for the Funds to operate.

As compensation for its services and its assumption of certain expenses, each Fund pays the Advisor a management fee equal to a percentage of a Fund’s average daily net assets that is calculated daily and paid monthly, as follows:

The Advisor may voluntarily waive any portion of its advisory fee from time to time, and may discontinue or modify any such voluntary limitations in the future at its discretion.

The Advisor serves as investment advisor to each Fund pursuant to an Investment Advisory Agreement (the “Advisory Agreement”) and the Subadvisor serves as investment subadvisor to each Fund pursuant to an Investment Subadvisory Agreement (the “Subadvisory Agreement”). The Advisory Agreement and Subadvisory Agreement were approved by the Independent Trustees of the Trust. The basis for the Trustees’ approval of the Advisory Agreement and Subadvisory Agreement are available in the Trust’s Annual or Semiannual Report to shareholders.

46

Section 15(a) of the 1940 Act requires that all contracts pursuant to which persons serve as investment advisors to investment companies be approved by shareholders. As interpreted, this requirement also applies to the appointment of subadvisors to the Funds. The Advisor and the Trust have obtained an exemptive order (the “Order”) from the SEC permitting the Advisor, on behalf of the Funds and subject to the approval of the Board, including a majority of the Independent Trustees, to hire or terminate unaffiliated subadvisors and to modify any existing or future subadvisory agreement with unaffiliated subadvisors without shareholder approval. This authority is subject to certain conditions. A Fund will notify shareholders and provide them with certain information required by the Order within 90 days of hiring a new subadvisor. A Fund’s sole shareholder has approved the use of the Order. Please see the SAI for more information on the Order.

Expense Limitation Agreement

The Advisor has contractually agreed to waive or reduce its management fee and/or reimburse expenses of the Funds in an amount that limits “Total Annual Fund Operating Expenses” ​(excluding interest, taxes, brokerage commissions, dividend payments on short sales, acquired fund fees and expenses, other expenditures which are capitalized in accordance with generally accepted accounting principles, other extraordinary expenses not incurred in the ordinary course of a Fund’s business, and amounts, if any, payable pursuant to a plan adopted in accordance with Rule 12b-1 under the 1940 Act) to not more than the average daily net assets of a Fund as follows. The agreement will remain in effect unless terminated by the Board of Trustees of the Funds:

Subadvisor

Pursuant to an investment subadvisory agreement with the Advisor, MacKay Shields LLC serves as the subadvisor to each Fund and makes investment decisions, and buys and sells securities for the Funds. Under the supervision of the Advisor, the Subadvisor is responsible for making the specific decisions about the following: (i) buying, selling and holding securities; (ii) selecting brokers and brokerage firms to trade for them; (iii) maintaining accurate records; and, if possible, (iv) negotiating favorable commissions and fees with the brokers and brokerage firms. For these services, the Subadvisor is paid a monthly fee by the Advisor out of the Advisor’s management fee, not a Fund. See the SAI for a breakdown of fees. To the extent that the Advisor has agreed to waive its management fee or reimburse expenses for a Fund, the Subadvisor has agreed to waive or reimburse its fee proportionately. The basis for the Board’s approval of the Subadvisory Agreement is available in the Trust’s Annual report to shareholders.

The Subadvisor was incorporated in 1969 and has been registered as an investment advisor with the SEC since 1969. Today the Subadvisor is an indirect wholly-owned subsidiary of New York Life. The Subadvisor’s principal office is located at 1345 Avenue of the Americas, New York, New York 10105. As of June 30, 2022, the Subadvisor had approximately $132 billion in assets under management.

Frequent Trading

The Board has not adopted policies and procedures with respect to frequent purchases and redemptions of Shares by Fund shareholders (“market timing”). In determining not to adopt market timing policies and procedures, the Board noted that the Funds are expected to be attractive to active institutional and retail investors interested in buying and selling Shares on a short-term basis. In addition, the Board considered that, unlike traditional mutual funds, Shares can only be purchased and redeemed directly from a Fund in Creation Units by Authorized Participants, and that the vast majority of trading in Shares occurs on the Secondary Market. Because Secondary Market trades do not involve a Fund directly, it is unlikely those trades would cause many of the harmful effects of market timing, including dilution, disruption of portfolio management, increases in a Fund’s trading costs and the realization of capital gains. With respect to trades directly with the Funds, to the extent effected in-kind (namely, for securities), those trades do not cause any of the harmful effects that may result from frequent cash trades. To the extent trades are effected in whole or in part in cash, the Board noted that those trades could result in dilution of a Fund and increased transaction costs (a Fund may impose higher transaction fees to offset these increased costs), which could negatively impact a Fund’s ability to achieve its investment objective. However, the Board also noted that direct trading on a short-term basis by Authorized Participants is critical to ensuring that Shares trade at or close to NAV. Given this structure, the Board determined that it is not necessary to adopt market timing policies and procedures. Each Fund reserves the right to reject any purchase order at any time and reserves the right to impose restrictions on disruptive or excessive trading in Creation Units.

The Board has instructed the officers of the Trust to review reports of purchases and redemptions of Creation Units on a regular basis to determine if there is any unusual trading in the Funds. The officers of the Trust will report to the Board any such unusual trading in Creation Units that is disruptive to the Funds. In such event, the Board may reconsider its decision not to adopt market timing policies and procedures.

Distribution and Service Plan

The Board has adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the 1940 Act. In accordance with its Rule 12b-1 plan, each Fund is authorized to pay an amount up to 0.25% of its average daily net assets each year to finance activities primarily intended to result in the sale of Creation Units of each Fund or the provision of investor services. No Rule 12b-1 fees are currently paid by the Funds and there are no plans to impose these fees. However, in the event Rule 12b-1 fees are charged in the future, they will be paid out of the respective Fund’s assets, and over time these fees will increase the cost of your investment and they may cost you more than certain other types of sales charges.

The Advisor and its affiliates may, out of their own resources, pay amounts (“Payments”) to third-parties for distribution or marketing services on behalf of the Funds. The making of these payments could create a conflict of interest for a financial intermediary receiving such payments. The Advisor may make Payments for such third-parties to organize or participate in activities that are designed to make registered representatives, other

49​

professionals and individual investors more knowledgeable about ETFs, including ETFs advised by the Advisor, or for other activities, such as participation in marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems (“Education Costs”). The Advisor also may make Payments to third-parties to help defray costs typically covered by a trading commission, such as certain printing, publishing and mailing costs or materials relating to the marketing of services related to exchange-traded products (such as commission-free trading platforms) or exchange-traded products in general (“Administrative Costs”).

Determination of Net Asset Value (NAV)

The NAV of the Shares for a Fund is equal to the Fund’s total assets minus its total liabilities divided by the total number of Shares outstanding. Interest and investment income on a Fund’s assets accrue daily and are included in the Fund’s total assets. Expenses and fees (including investment advisory, management, administration and distribution fees, if any) accrue daily and are included in a Fund’s total liabilities. The NAV that is published is rounded to the nearest cent; however, for purposes of determining the price of Creation Units, the NAV is calculated to eight decimal places. The NAV is calculated by the Administrator and Custodian and determined each day the NYSE Arca is open for trading as of the close of regular trading on the NYSE Arca (ordinarily 4:00 p.m. Eastern time).

A Fund typically values fixed-income portfolio securities using last available bid prices or current market quotations provided by dealers or prices (including evaluated prices) supplied by the Fund’s approved independent third-party pricing services. Pricing services may use matrix pricing or valuation models that utilize certain inputs and assumptions to derive values. Pricing services generally value fixed-income securities assuming orderly transactions of an institutional round lot size, but a Fund may hold or transact in such securities in smaller odd lot sizes. Odd lots often trade at different prices that may be above or below the price at which the pricing service has valued the security. An amortized cost method of valuation may be used with respect to debt obligations with sixty days or less remaining to maturity unless the Advisor determines in good faith that such method does not represent fair value.

Generally, trading in U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Funds are determined as of such times.

When market quotations or prices are not readily available or are deemed unreliable or not representative of an investment’s fair value, investments are valued using fair value pricing as determined in good faith by the Advisor under procedures established by and under the general supervision and responsibility of the Board. The Advisor may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its lack of liquidity or other reason, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, or if the trading market on which a security is listed is suspended or closed and no appropriate alternative trading market is available.

The frequency with which the Funds’ investments are valued using fair value pricing is primarily a function of the types of securities and other assets in which the respective Fund invests pursuant to its investment objective, strategies and limitations. If the Funds invest in other open-end management investment companies registered under the 1940 Act, they may rely on the NAVs of those companies to value the shares they hold of them. Those companies may also use fair value pricing under some circumstances.

Valuing each Fund’s investments using fair value pricing results in using prices for those investments that may differ from current market valuations. Accordingly, fair value pricing could result in a difference between the prices used to calculate NAV and the prices used to determine each Fund’s indicative intra-day value (“IIV”), which could result in the market prices for Shares deviating from NAV.

Premium/Discount Information

Information regarding the extent and frequency with which market prices of Shares have tracked the relevant Fund’s NAV for the most recently completed calendar year and the quarters since that year will be available without charge on the Funds’ website at newyorklifeinvestments.com/etf.

50

Indicative Intra-Day Value

The approximate value of a Fund’s investments on a per-Share basis, the Indicative Intra-Day Value, or IIV, is disseminated every 15 seconds during hours of trading on the NYSE Arca. The IIV should not be viewed as a “real-time” update of NAV because the IIV may not be calculated in the same manner as NAV, which is computed once per day.

Solactive AG, an independent third party calculator calculates the IIV for each Fund during hours of trading on the NYSE Arca by dividing the “Estimated Fund Value” as of the time of the calculation by the total number of outstanding Shares of that Fund. “Estimated Fund Value” is the sum of the estimated amount of cash held in a Fund’s portfolio, the estimated amount of accrued interest owed to the Fund and the estimated value of the securities held in the Fund’s portfolio, minus the estimated amount of the Fund’s liabilities. The IIV will be calculated based on the same portfolio holdings disclosed on the Trust’s website.

Each Fund provides the independent third party calculator with information to calculate the IIV, but the Funds are not involved the actual calculation of the IIV and is not responsible for the calculation or dissemination of the IIV. The Funds make no warranty as to the accuracy of the IIV.

Dividends, Distributions and Taxes

Net Investment Income and Capital Gains

As a Fund shareholder, you are entitled to your share of the Fund’s distributions of net investment income and net realized capital gains on its investments. The Funds pay out substantially all of their net earnings to their shareholders as “distributions.”

The Funds typically earn interest from debt securities. These amounts, net of expenses, typically are passed along to Fund shareholders as dividends from net investment income. The Funds realize capital gains or losses whenever they sell securities. Net capital gains typically are passed along to shareholders as “capital gain distributions.”

Net investment income and net capital gains typically are distributed to shareholders at least annually. Dividends may be declared and paid more frequently to comply with the distribution requirements of the U.S. Internal Revenue Code of 1986, as amended (the “Code”). In addition, the Funds may decide to distribute at least annually amounts representing the full dividend yield net of expenses on the underlying investment securities, as if the Funds owned the underlying investment securities for the entire dividend period, in which case some portion of each distribution may result in a return of capital. You will be notified regarding the portion of a distribution that represents a return of capital.

Distributions in cash may be reinvested automatically in additional Shares of a Fund only if the broker through which you purchased Shares makes such option available.

U.S. Federal Income Taxation

The following is a summary of certain U.S. federal income tax considerations applicable to an investment in Shares of a Fund. The summary is based on the Code, U.S. Treasury Department regulations promulgated thereunder, and judicial and administrative interpretations thereof, all as in effect on the date of this Prospectus and all of which are subject to change, possibly with retroactive effect. In addition, this summary assumes that a Fund shareholder holds Shares as capital assets within the meaning of the Code and does not hold Shares in connection with a trade or business. This summary does not address all potential U.S. federal income tax considerations possibly applicable to an investment in Shares of a Fund, and does not address the consequences to Fund shareholders subject to special tax rules, including, but not limited to, partnerships and the partners therein, tax-exempt shareholders, regulated investment companies (“RICs”), real estate investment trusts (“REITs”), real estate mortgage investment conduits (“REMICs”), those who hold Shares through an IRA, 401(k) plan or other tax-advantaged account, and, except to the extent discussed below, “non-U.S. shareholders” ​(as defined below). This discussion does not discuss any aspect of U.S. state, local, estate, and gift, or non-U.S., tax law. Furthermore, this discussion is not intended or written to be legal or tax advice to any shareholder in a Fund or other person and is not intended or written to be used or relied on, and cannot be used or relied on, by any such person for the purpose of avoiding any U.S. federal tax penalties that may be imposed on such person. Prospective Fund shareholders are urged to consult their own tax advisors with respect to the specific U.S. federal, state and local, and non-U.S., tax consequences of investing in Shares, based on their particular circumstances.

51​

The Funds have not requested and will not request an advance ruling from the U.S. Internal Revenue Service (the “IRS”) as to the U.S. federal income tax matters described below. The IRS could adopt positions contrary to those discussed below and such positions could be sustained. Prospective investors should consult their own tax advisors with regard to the U.S. federal tax consequences of the purchase, ownership and disposition of Shares, as well as the tax consequences arising under the laws of any state, locality, non-U.S. country or other taxing jurisdiction. The following information supplements, and should be read in conjunction with, the section in the SAI entitled “U.S. Federal Income Taxation.”

Tax Treatment of a Fund

Each Fund intends to continue to qualify and elect to be treated as a separate RIC under the Code. To qualify and remain eligible for the special tax treatment accorded to RICs, each Fund must meet certain annual income and quarterly asset diversification requirements and must distribute annually at least 90% of the sum of (i) its “investment company taxable income” ​(which includes dividends, interest and net short-term capital gains) and (ii) its net tax-exempt interest.

As a RIC, a Fund generally will not be required to pay corporate-level U.S. federal income taxes on any ordinary income or capital gains that it distributes to its shareholders. If a Fund fails to qualify as a RIC for any year (subject to certain curative measures allowed by the Code), the Fund will be subject to regular corporate-level U.S. federal income tax in that year on all of its taxable income, regardless of whether the Fund makes any distributions to its shareholders. In addition, in such case, distributions will be taxable to a Fund’s shareholders generally as ordinary dividends to the extent of the Fund’s current and accumulated earnings and profits. The remainder of this discussion assumes that the Funds will qualify for the special tax treatment accorded to RICs.

A Fund generally will be subject to a 4% excise tax on certain undistributed income if the Fund does not distribute to its shareholders in each calendar year an amount at least equal to the sum of 98% of its ordinary income for the calendar year (taking into account certain deferrals and elections), 98.2% of its capital gain net income (adjusted for certain ordinary losses) for the twelve months ended October 31 of such year (or later if the Fund is permitted to elect and so elects), plus 100% of any undistributed amounts from prior years. For these purposes, a Fund will be treated as having distributed any amount on which it has been subject to U.S. corporate income tax for the taxable year ending within the calendar year. Each Fund intends to make distributions necessary to avoid this 4% excise tax, although there can be no assurance that it will be able to do so.

A Fund may be required to recognize income in advance of receiving the related cash payment. For example, if a Fund invests in original issue discount obligations (such as zero coupon debt instruments or debt instruments with payment-in-kind interest), the Fund will be required to include in income each year a portion of the original issue discount that accrues over the term of the obligation, even if the related cash payment is not received by the Fund until a later year. Under the “wash sale” rules, a Fund may not be able to deduct currently a loss on a disposition of a portfolio security. As a result, a Fund may be required to make an annual income distribution greater than the total cash actually received during the year. Such distribution may be made from the existing cash assets of the Fund or cash generated from selling portfolio securities. The Fund may realize gains or losses from such sales, in which event its shareholders may receive a larger capital gain distribution than they would in the absence of such transactions.

Tax Treatment of Fund Shareholders

Taxation of U.S. Shareholders

The following is a summary of certain U.S. federal income tax consequences of the purchase, ownership and disposition of Shares applicable to “U.S. shareholders.” For purposes of this discussion, a “U.S. shareholder” is a beneficial owner of Shares who, for U.S. federal income tax purposes, is (i) an individual who is a citizen or resident of the U.S.; (ii) a corporation (or an entity treated as a corporation for U.S. federal income tax purposes) created or organized in the U.S. or under the laws of the U.S., or of any state thereof, or the District of Columbia; (iii) an estate, the income of which is includable in gross income for U.S. federal income tax purposes regardless of its source; or (iv) a trust, if  (1) a U.S. court is able to exercise primary supervision over the administration of such trust and one or more U.S. persons have the authority to control all substantial decisions of the trust, or (2) the trust has a valid election in place to be treated as a U.S. person.

52

Fund Distributions. A majority of each Fund’s distributions to its shareholders is expected to be excluded from gross income for U.S. federal income tax purposes as “exempt-interest dividends.” Notwithstanding the foregoing, Fund shareholders should be aware of the following points:

​

•

Some tax-exempt distributions from a Fund may be subject to the federal alternative minimum tax on individuals. For tax years beginning after December 31, 2022, tax exempt interest dividends may affect the corporate alternative minimum tax for certain corporations.

​

​

•

Exempt-interest dividends may have other tax consequences to certain shareholders (for example, they may result in a portion of a shareholder’s social security income being subject to federal income tax), and a shareholder may not be entitled to deduct the interest expense on debt deemed to be incurred or continued to purchase or carry Shares.

​

​

•

Tax-exempt distributions from a Fund may be subject to state and local taxes.

​

​

•

The Funds may earn taxable income. In other words, shareholders of a Fund may earn taxable income from the Fund even though the Fund generally intends to be tax-free to shareholders.

​

​

•

Capital gains of a Fund are not tax-free to shareholders.

​

​

•

Any time a shareholder sells Shares (even Shares of a generally tax-free Fund), such shareholder will be subject to tax on any gain.

​

​

•

If a shareholder sells Shares of a Fund at a loss after receiving an exempt-interest dividend, and the shareholder has held the Shares for six months or less, then such shareholder may not be allowed to claim a loss on the sale.

​

In general, taxable Fund distributions are subject to U.S. federal income tax when paid, regardless of whether they consist of cash or property, and regardless of whether they are re-invested in Shares. However, any Fund distribution declared in October, November or December of any calendar year and payable to shareholders of record on a specified date during such month will be deemed to have been received by each Fund shareholder on December 31 of such calendar year, provided such dividend is actually paid during January of the following calendar year.

Distributions of a Fund’s taxable net investment income (except, as discussed below, qualified dividend income, if any) and net short-term capital gains in excess of net long-term capital losses (collectively referred to as “ordinary income dividends”) are taxable as ordinary income to the extent of the Fund’s current and accumulated earnings and profits. To the extent designated as capital gain dividends by a Fund, distributions of a Fund’s net long-term capital gains in excess of net short-term capital losses (“net capital gain”) are taxable at long-term capital gain tax rates to the extent of a Fund’s current and accumulated earnings and profits, regardless of a Fund shareholder’s holding period in the Shares. Distributions of qualified dividend income are, to the extent of the Fund’s current and accumulated earnings and profits, taxed to certain non-corporate Fund shareholders at the rates generally applicable to long-term capital gain, provided that the Fund shareholder meets certain holding period and other requirements with respect to the distributing Shares and the distributing Fund meets certain holding period and other requirements with respect to its dividend-paying stocks. Substitute payments received on Shares that are lent out will be ineligible for being reported as qualified dividend income. Given their investment strategy, the Funds do not anticipate that a significant portion of their distributions will be eligible for qualifying dividend treatment. If a Fund pays a dividend that would be “qualified” dividend income for individuals, corporate shareholders may be entitled to a dividends received deduction.

An election may be available to you to defer recognition of the gain attributable to a capital gain dividend if you make certain qualifying investments within a limited time. You should talk to your tax advisor about the availability of this deferral election and its requirements.

Each Fund intends to distribute its net capital gain at least annually. However, by providing written notice to its shareholders no later than 60 days after its year-end, a Fund may elect to retain some or all of its net capital gain and designate the retained amount as a “deemed distribution.” In that event, the Fund pays U.S. federal income tax on the retained net capital gain, and each Fund shareholder recognizes a proportionate share of the Fund’s undistributed net capital gain. In addition, each Fund shareholder can claim a tax credit or refund

53​

for the shareholder’s proportionate share of the Fund’s U.S. federal income taxes paid on the undistributed net capital gain and increase the shareholder’s tax basis in the Shares by an amount equal to the shareholder’s proportionate share of the Fund’s undistributed net capital gain, reduced by the amount of the shareholder’s tax credit or refund.

Distributions in excess of a Fund’s current and accumulated earnings and profits will, as to each shareholder, be treated as a tax-free return of capital to the extent of the shareholder’s tax basis in its Shares of the Fund, and generally as capital gain thereafter. Any such distribution will reduce the shareholder’s tax basis in the Shares, and thus will increase the shareholder’s capital gain, or decrease the capital loss, recognized upon a sale or exchange of Shares.

In addition, individuals with adjusted gross incomes above certain threshold amounts (and certain trusts and estates) generally are subject to a 3.8% Medicare tax on “net investment income” in addition to otherwise applicable U.S. federal income tax. “Net investment income” generally will include taxable dividends (including capital gain dividends) received from a Fund and net gains from the redemption or other disposition of Shares. Please consult your tax advisor regarding this tax.

Investors considering buying Shares just prior to a distribution should be aware that, although the price of the Shares purchased at such time may reflect the forthcoming distribution, such distribution nevertheless may be taxable (as opposed to a non-taxable return of capital).

Sales of Shares. Any capital gain or loss realized upon a sale or exchange of Shares (including an exchange of Shares of one Fund for Shares of another Fund) generally is treated as a long-term gain or loss if the Shares have been held for more than one year. Any capital gain or loss realized upon a sale or exchange of Shares held for one year or less generally is treated as a short-term gain or loss, except that any capital loss on the sale or exchange of Shares held for six months or less, to the extent not disallowed as discussed in the next sentence, is treated as long-term capital loss to the extent that capital gain dividends were paid (or deemed to be paid) with respect to the Shares. Furthermore, a loss realized by a shareholder on the sale or exchange of Shares of a Fund with respect to which exempt-interest dividends have been paid may, to the extent of such exempt-interest dividends, be disallowed if such Shares have been held by the shareholder for six months or less at the time of their disposition. An election may be available to you to defer recognition of capital gain if you make certain qualifying investments within a limited time. You should talk to your tax advisor about the availability of this deferral election and its requirements.

Creation Unit Issues and Redemptions. On an issue of Shares of a Fund as part of a Creation Unit where the creation is conducted in-kind, an Authorized Participant recognizes capital gain or loss equal to the difference between (i) the fair market value (at issue) of the issued Shares (plus any cash received by the Authorized Participant as part of the issue) and (ii) the Authorized Participant’s aggregate basis in the exchanged securities (plus any cash paid by the Authorized Participant as part of the issue). On a redemption of Shares as part of a Creation Unit where the redemption is conducted in-kind, an Authorized Participant recognizes capital gain or loss equal to the difference between (i) the fair market value (at redemption) of the securities received (plus any cash received by the Authorized Participant as part of the redemption) and (ii) the Authorized Participant’s basis in the redeemed Shares (plus any cash paid by the Authorized Participant as part of the redemption). However, the IRS may assert, under the “wash sale” rules or on the basis that there has been no significant change in the Authorized Participant’s economic position, that any loss on creation or redemption of Creation Units cannot be deducted currently.

In general, any capital gain or loss recognized upon the issue or redemption of Shares (as components of a Creation Unit) is treated either as long-term capital gain or loss, if the deposited securities (in the case of an issue) or the Shares (in the case of a redemption) have been held for more than one year, or otherwise as short-term capital gain or loss. However, any capital loss on a redemption of Shares held for six months or less, to the extent not disallowed as discussed in the next sentence, is treated as long-term capital loss to the extent that capital gain dividends were paid (or deemed to be paid) with respect to such Shares. Furthermore, a loss realized on the redemption of Shares of a Fund with respect to which exempt-interest dividends have been paid may, to the extent of such exempt-interest dividends, be disallowed if such Shares have been held for six months or less at the time of their disposition.

Back-Up Withholding

A Fund (or a financial intermediary such as a broker through which a shareholder holds Shares in a Fund) may be required to report certain information on a Fund shareholder to the IRS and withhold U.S. federal income tax (“backup withholding”) at a current rate of 24% from taxable distributions and redemption or sale proceeds payable to the Fund shareholder if  (i) the Fund shareholder fails to provide the Fund with a correct taxpayer identification number or make required certifications, or if the IRS notifies the Fund that the Fund shareholder is otherwise subject to backup withholding, and (ii) the Fund shareholder is not otherwise exempt from backup withholding. Non-U.S. shareholders can qualify for exemption from backup withholding by submitting a properly completed IRS Form W-8BEN or W-8BEN-E. Backup withholding is not an additional tax and any amount withheld may be credited against a Fund shareholder’s U.S. federal income tax liability.

Taxation of Non-U.S. Shareholders

The following is a summary of certain U.S. federal income tax consequences of the purchase, ownership and disposition of Shares applicable to “non-U.S. shareholders.” For purposes of this discussion, a “non-U.S. shareholder” is a beneficial owner of Shares that is not a U.S. shareholder (as defined above) and is not an entity or arrangement treated as a partnership for U.S. federal income tax purposes. The following discussion is based on current law and is for general information only. It addresses only selected, and not all, aspects of U.S. federal income taxation applicable to non-U.S. shareholders.

As indicated above, a majority of each Fund’s distributions to its shareholders, including its non-U.S. shareholders, is expected to be excluded from gross income for U.S. federal income tax purposes as exempt-interest dividends. However, with respect to non-U.S. shareholders of a Fund, the Fund’s other ordinary income dividends generally will be subject to U.S. federal withholding tax at a rate of 30% (or at a lower rate established under an applicable tax treaty), subject to certain exceptions for “interest-related dividends” and “short-term capital gain dividends” discussed below. The Funds will not pay any additional amounts to shareholders in respect of any amounts withheld. U.S. federal withholding tax generally will not apply to any gain realized by a non-U.S. shareholder in respect of a Fund’s net capital gain. Special rules (not discussed herein) apply with respect to dividends of a Fund that are attributable to gain from the sale or exchange of “U.S. real property interests.”

In general, all “interest-related dividends” and “short-term capital gain dividends” ​(each defined below) will not be subject to U.S. federal withholding tax, provided that, among other requirements, the non-U.S. shareholder furnished the Fund with a completed IRS Form W-8BEN or W-8BEN-E, as applicable, (or acceptable substitute documentation) establishing the non-U.S. shareholder’s non-U.S. status and the Fund does not have actual knowledge or reason to know that the non-U.S. shareholder would be subject to such withholding tax if the non-U.S. shareholder were to receive the related amounts directly rather than as dividends from the Fund. “Interest-related dividends” generally means dividends designated by a Fund as attributable to such Fund’s U.S.-source interest income, other than certain contingent interest and interest from obligations of a corporation or partnership in which such Fund is at least a 10% shareholder, reduced by expenses that are allocable to such income. “Short-term capital gain dividends” generally means dividends designated by a Fund as attributable to the excess of such Fund’s net short-term capital gain over its net long-term capital loss. Depending on its circumstances, a Fund may treat such dividends, in whole or in part, as ineligible for these exemptions from withholding.

For years after December 31, 2022, amounts paid to or recognized by a non-U.S. affiliate that are excluded from tax under the portfolio interest, capital gains dividends, short-term capital gains or tax-exempt interest dividend exceptions or applicable treaties, may be taken into consideration in determining whether a corporation is an “applicable corporation” subject to a 15% minimum tax on adjusted financial statement income.

In general, subject to certain exceptions, non-U.S. shareholders will not be subject to U.S. federal income or withholding tax in respect of a sale or other disposition of Shares of a Fund.

To claim a credit or refund for any Fund-level taxes on any undistributed net capital gain (as discussed above) or any taxes collected through back-up withholding (discussed below), a non-U.S. shareholder must obtain a U.S. taxpayer identification number and file a U.S. federal income tax return even if the non-U.S. shareholder would not otherwise be required to do so.

Foreign Account Tax Compliance Act

The U.S. Foreign Account Tax Compliance Act (“FATCA”) generally imposes a 30% withholding tax on “withholdable payments” ​(defined below) made to (i) a “foreign financial institution” ​(“FFI”), unless the FFI enters into an agreement with the IRS to provide information regarding certain of its direct and indirect U.S.

55​

account holders and satisfy certain due diligence and other specified requirements, and (ii) a “non-financial foreign entity” ​(“NFFE”) unless such NFFE provides certain information about its direct and indirect “substantial U.S. owners” to the withholding agent or certifies that it has no such U.S. owners. The beneficial owner of a “withholdable payment” may be eligible for a refund or credit of the withheld tax. The U.S. government also has entered into intergovernmental agreements with other jurisdictions to provide an alternative, and generally easier, approach for FFIs to comply with FATCA. If the shareholder is a tax resident in a jurisdiction that has entered into an intergovernmental agreement with the U.S. government, the shareholder will be required to provide information about the shareholder’s classification and compliance with the intergovernmental agreement.

“Withholdable payments” generally include, among other items, U.S.-source interest and dividends, and gross proceeds from the sale or disposition of property of a type that can produce U.S.-source interest or dividends. However, proposed regulations may eliminate the requirements to withhold on payments of gross proceeds from dispositions.

A Fund or a shareholder’s broker may be required to impose a 30% withholding tax on withholdable payments to a shareholder if the shareholder fails to provide the Fund with the information, certifications or documentation required under FATCA, including information, certification or documentation necessary for the Fund to determine if the shareholder is a non-U.S. shareholder or a U.S. shareholder and, if it is a non-U.S. shareholder, if the non-U.S. shareholder has “substantial U.S. owners” and/or is in compliance with (or meets an exception from) FATCA requirements. A Fund will not pay any additional amounts to shareholders in respect of any amounts withheld. The Fund may disclose any shareholder information, certifications or documentation to the IRS or other parties as necessary to comply with FATCA.

The requirements of, and exceptions from, FATCA are complex. All prospective shareholders are urged to consult their own tax advisors regarding the potential application of FATCA with respect to their own situation.

Code of Ethics

The Trust, Advisor, Subadvisor and Distributor each have adopted a code of ethics under Rule 17j-1 of the 1940 Act that is designed to prevent affiliated persons of the Trust, the Advisor, the Subadvisor and the Distributor from engaging in deceptive, manipulative or fraudulent activities in connection with securities held or to be acquired by the Funds (which may also be held by persons subject to a code). There can be no assurance that the codes will be effective in preventing such activities. The codes permit personnel subject to them to invest in securities, including securities that may be held or purchased by the Funds. The codes are on file with the SEC and are available to the public.

Fund Website and Disclosure of Portfolio Holdings

The Advisor maintains a website for the Funds at newyorklifeinvestments.com/etf. The website for the Funds contains the following information, on a per-Share basis, for each Fund: (1) the prior Business Day’s NAV; (2) the reported midpoint of the bid-ask spread at the time of NAV calculation (the “Bid-Ask Price”); (3) a calculation of the premium or discount of the Bid-Ask Price against such NAV; and (4) data in chart format displaying the frequency distribution of discounts and premiums of the Bid-Ask Price against the NAV, within appropriate ranges, for each of the four previous calendar quarters (or for the life of a Fund if, shorter). In addition, on each Business Day, before the commencement of trading in Shares on the NYSE Arca, each Fund will disclose on its website (newyorklifeinvestments.com/etf) the identities and quantities of the portfolio securities and other assets held by each Fund that will form the basis for the calculation of NAV at the end of the Business Day.

A description of each Fund’s policies and procedures with respect to the disclosure of the Fund’s portfolio securities is available in the SAI.
