Summary Information  

IQ Real Return ETF

Investment Objective

The Fund seeks investment results that correspond (before fees and expenses) generally to the price and yield performance of its underlying index, the IQ Real Return Index (the “Underlying Index”).

Fees and Expenses of the Fund

This table describes fees and expenses that you may pay if you buy, sell or hold shares of the Fund (“Shares”). Investors may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example set forth below.

Shareholder Fees (fees paid directly from your investment):

None

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment):

Management Fee	0.48%
Distribution and/or Service (12b-1) Fees	0.00%
Other Expenses	0.01%
Acquired Fund Fees & Expenses(a)	0.17%
Total Annual Fund Operating Expenses(a)	0.66%
Fee Waiver(b)	0.28%
Total Annual Fund Operating Expenses After Fee Waiver	0.38%

(a)

The Total Annual Fund Operating Expenses may not correlate to the ratio of expenses to average net assets as reported in the “Financial Highlights” section of the Prospectus, which reflects the operating expenses of the Fund and does not include Acquired Fund Fees & Expenses. Acquired Fund Fees & Expenses represent the Fund’s pro rata share of fees and expenses incurred indirectly as a result of investing in other funds, including ETFs and money market funds.

(b)

IndexIQ Advisors LLC (the “Advisor”) has contractually agreed, until August 31, 2022, to waive a portion of the management fee equal to 0.28% of average daily net assets.

Example. This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. This example does not take into account brokerage commissions that you pay when purchasing or selling Shares of the Fund.

The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain at current levels. The return of 5% and estimated expenses are for illustration purposes only,

2

and should not be considered indicators of expected Fund expenses or performance, which may be greater or less than the estimates. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

1 Year	3 Years	5 Years	10 Years
$39	$183	$340	$796

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 66% of the average value of its portfolio. This rate excludes the value of portfolio securities received or delivered as a result of in-kind creations or redemptions of the Shares.

Principal Investment Strategies

The Fund is a “fund of funds” which means it invests, under normal circumstances, at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in the investments included in its Underlying Index, which includes underlying funds. The Underlying Index consists of a number of components (“Underlying Index Components”) selected in accordance with the rules-based methodology of such Underlying Index, which was developed by IndexIQ LLC (“IndexIQ”), an affiliate of IndexIQ Advisors LLC, the Fund’s investment advisor (the “Advisor”). Such Underlying Index Components will include primarily ETFs and/or other exchange-traded vehicles issuing equity securities organized in the U.S., such as exchange-traded commodity pools (“ETVs”), and may include exchange-traded notes (“ETNs”) (such ETFs, ETVs and ETNs are referred to collectively as “exchange-traded products” or “ETPs”). The Fund may also invest in one or more financial instruments, including but not limited to futures contracts and swap agreements (collectively, “Financial Instruments”).

The Fund employs a “passive management” — or indexing — investment approach designed to track the performance of the Underlying Index. The Underlying Index seeks to provide investors with a hedge against the inflation rate by providing a “real return” or a return above the rate of inflation, as represented by the CPI (the “Strategy”). The CPI, or the Consumer Price Index, which is published by the Bureau of Labor Statistics, is a measure of the average change in prices over time of goods and services purchased by households. The CPI is reported with monthly frequency, but due to seasonality and other factors the monthly change in

3​

the CPI is reported both as the 1-month change and also on a rolling 12-month basis (the “Rolling 12-month CPI Returns”). It is the Rolling 12-month CPI Returns, not the monthly returns of the CPI, that the Underlying Index incorporates into its construction process.

The Underlying Index includes exposures to asset classes whose returns incorporate inflation expectations in an attempt to achieve its investment objective. This is based on the premise that capital market returns tend to be forward looking and anticipate economic developments, including inflation expectations. Since the Underlying Index’s objective is to provide a “real return,” as described above, the index construction process involves adding a real return target over and above the CPI returns and using the resulting “nominal returns” ​(i.e., inflation plus real return) to determine the weights of the Underlying Index Components.

The Underlying Index Components of this Strategy generally provide exposures to:

•

U.S. large capitalization equity;

•

U.S. small capitalization equity;

•

Foreign equity (Europe, Australasia & Far East);

•

U.S. government short-, intermediate-, and long-term maturity obligations;

•

Foreign currencies and currency futures;

•

U.S. real estate; and

•

Commodities.

The Underlying Index may include as a component one or more ETFs advised by the Advisor (“Affiliated ETFs”) and the Fund will typically invest in any Affiliated ETF included in the Underlying Index. The Fund also may invest in Affiliated ETFs that are not components of the index if such an investment will help the Fund track the Underlying Index.

The weights of the Underlying Index Components are rebalanced on a monthly basis. Annually, IndexIQ conducts a review process pursuant to which it may reconstitute the Underlying Indexes by adding or subtracting Underlying Index Components according to IndexIQ’s rules-based process.

Principal Risks

As with all investments, there are certain risks of investing in the Fund. The Fund’s Shares will change in value and you could lose money by investing in the Fund. An investment in the Fund does not represent a complete investment program. An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, the Advisor or any of its affiliates. You should consider carefully the following risks before investing in the Fund.

4

Authorized Participant Concentration Risk

Only certain large institutions may engage in creation or redemption transactions directly with the Fund (each, an “Authorized Participant”). The 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 those Authorized Participants exit the business or are unable to proceed with creation and/or redemption orders with the Fund and no other Authorized Participant is able to step forward to engage in creation and redemption transactions with the Fund, Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts and/or delisting.

Cyber Security Risk

The Fund is susceptible to operational risks through breaches in cyber security. Such events may cause the Fund to lose proprietary information, suffer data corruption or lose operational capacity and could cause the Fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. In addition, cyber security breaches of the securities issuers or the Fund’s third-party service providers can also subject the Fund to many of the same risks associated with direct cyber security breaches. Although the Fund has established risk management systems designed to reduce the risks associated with cyber security, there is no guarantee that such efforts will succeed.

Derivatives Risk

Derivatives are investments whose value depends on (or is derived from) the value of an underlying instrument, such as a security, asset, reference rate or index and involve risks different from, and possibly greater than, the risks associated with other investments. These risks include: (i) the risk that the counterparty to a derivatives transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to, changing supply and demand relationships, government programs and policies, national and international political and economic events, changes in interest rates, inflation and deflation, and changes in supply and demand relationships. Unlike other investments, derivative contracts often have leverage inherent in their terms. The use of leveraged derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on the Fund’s Share price. The effects of leverage may also cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet collateral segregation requirements.

5​

Exchange Traded Products Risk

Unlike an investment in a mutual fund, the value of the Fund’s investment in other exchange-traded funds or exchange-traded investment products (“ETPs”) is based on its market price (rather than NAV) and the Fund could lose money due to premiums/discounts of the ETP (which could cause the Fund to buy shares at market prices that are higher than their value or sell shares at market prices that are lower than their value); the failure of an active trading market to develop; or exchange trading halts or delistings. An investment in the Fund will entail more costs and expenses than a direct investment in any Underlying ETP. As the Fund’s allocations to Underlying ETPs changes, or the expense ratio of Underlying ETPs change, the operating expenses borne by the Fund from such investments may increase or decrease.

Index Risk

There is no guarantee that the Fund’s investment results will have a high degree of correlation to those of the Underlying Index or that the Fund will achieve its investment objective. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected for a period of time or at all, which may have an adverse impact on the Fund and its shareholders.

Market Risk

Market risks include political, regulatory, market and economic developments, including developments that impact specific economic sectors, industries or segments of the market, which may affect the Fund’s value. Turbulence in financial markets, tariffs and other protectionist measures, political developments and uncertainty, central bank policy, and reduced liquidity in equity, credit and fixed income markets may negatively affect many issuers worldwide, which could have an adverse effect on the Fund. During a general downturn in the securities markets, multiple asset classes may be negatively affected. 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 the 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.

6

Operational Risk

The 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 and Advisor 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.

Passive Management Risk

The Fund is not actively managed and instead seeks to track the performance of an index. Passive management has the following risks associated with it:

•

The Fund invests in the securities included in, or representative of, the Underlying Index. The provider of the Underlying Index or the index calculation agent may make errors. The index provider may include index constituents that should have been excluded, or it may exclude index constituents that should have been included. It also may include or exclude constituents at incorrect levels. This may result in the Fund, in turn, being correctly positioned to an index that has been incorrectly calculated. This could lead to losses to the Fund.

•

In seeking to track the Underlying Index’s performance, the Fund may be subject to tracking error, which is the divergence of the Fund’s performance from that of the Underlying Index. Tracking error may occur because of differences between the securities and other instruments held in the Fund’s portfolio and those included in the Underlying Index, pricing differences (including, as applicable, differences between a security’s price at the local market close and the Fund’s valuation of a security at the time of calculation of the Fund’s NAV), differences in transaction costs, the Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of dividends or interest, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, changes to the Underlying Index or the costs to the Fund of complying with various new or existing regulatory requirements. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not. This risk may be heightened during times of increased market volatility or other unusual market conditions.

•

The Fund generally will not attempt to take defensive positions in declining markets and generally will not sell a security because its

7​

issuer is in financial trouble, unless that security is removed from (or was no longer useful in tracking a component of) the Underlying Index.

Portfolio Turnover Risk

The Fund’s strategy may frequently involve buying and selling portfolio securities to rebalance the Fund’s investment exposures. High portfolio turnover may result in the Fund paying higher levels of transaction costs and generating greater tax liabilities for shareholders. Portfolio turnover risk may cause the Fund’s performance to be less than expected.

Secondary Market Trading Risk

Although the 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. In general, the trading of Shares on securities exchanges is subject to the risk of irregular trading activity and wide “bid/ask” spreads (which may be especially pronounced for smaller funds). Additionally, market makers are under no obligation to make a market in the 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 the Fund’s Shares or Authorized Participants stop submitting purchase or redemption orders for Creation Units, the 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.

Trading Price Risk

Shares of the Fund trade on securities exchanges at prices at, above or below the Fund’s most recent NAV. The NAV of the 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 the Fund’s Shares fluctuates continuously throughout trading hours based on both market supply of and demand for Shares and the underlying value of the Fund’s portfolio holdings or NAV. As a result, the trading prices of the Fund’s Shares may deviate significantly from NAV during periods of market volatility. Any of these factors, among others, may lead to the Fund’s Shares trading at a premium or discount to NAV. Although it is generally expected that the market price of the Shares of the Fund 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.

8

Risks of Underlying ETPs

The Fund may invest in the securities of other ETPs, including Affiliated ETFs. Investments in the Fund are subject to the risks associated with an investment in the Underlying ETPs. In addition to the risks described above, the following risks should also be considered when making an investment in the Fund.

•

Commodities Risk. Exposure to the commodities markets may subject the Fund to greater volatility than investments in traditional securities, and exposure to commodities, directly or through other securities, can cause the value of the Fund’s assets to decline or fluctuate in a rapid and unpredictable manner. The value of commodities may be affected by changes in overall market movements, real or perceived inflationary trends, commodity index volatility, changes in interest rates or currency exchange rates, population growth and changing demographics, international economic, political and regulatory developments, and factors affecting a particular region, industry or commodity, such as drought, floods, or other weather conditions, livestock disease, changes in storage costs, trade embargoes, competition from substitute products, transportation bottlenecks or shortages, fluctuations in supply and demand, and tariffs.

•

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 when due or otherwise honor its obligations. Changes in an issuer’s or counterparty’s credit rating or the market’s perception of an issuer’s or counterparty’s creditworthiness may also adversely affect the value of the Fund’s investment in that issuer. The degree of credit risk depends on an issuer’s or counterparty’s financial condition and on the terms of an obligation.

•

Currency Risk. Investments directly in foreign (non-U.S.) currencies or in securities that trade in, and receive revenues in, foreign (non-U.S.) currencies are subject to the risk that those currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency being hedged. Currency rates in foreign countries may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates, intervention (or the failure to intervene) by U.S. or foreign governments, central banks or supranational entities such as the International Monetary Fund, or by the imposition of currency controls or other political developments in the United States or abroad.

9​

•

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 the 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.

•

Equity Securities Risk. Investments in common stocks and other equity securities are particularly subject to the risk of changes in investors’ perceptions of the financial condition of an issuer, conditions affecting equity markets generally and political and/or economic events. Equity prices may also be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Holders of an issuer’s common stock may be subject to greater risks than holders of its preferred stock and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of an issuer.

•

Foreign Securities Risk. Investments in the securities of non-U.S. issuers involve risks beyond those associated with investments in U.S. securities. These additional risks include greater market volatility, the availability of less reliable financial information, higher transactional and custody costs, taxation by foreign governments, decreased market liquidity and political instability. Some countries and regions have experienced security concerns, war or threats of war and

10

aggression, terrorism, economic uncertainty, natural and environmental disasters and/or systemic market dislocations that have led, and in the future may lead, to increased short-term market volatility and may have adverse long-term effects on the U.S. and world economies and markets generally. Foreign issuers are often subject to less stringent requirements regarding accounting, auditing, financial reporting and record keeping than are U.S. issuers, and therefore not all material information will be available. Securities exchanges or foreign governments may adopt rules or regulations that may negatively impact the Fund’s ability to invest in foreign securities or may prevent the Fund from repatriating its investments. Less developed securities markets are more likely to experience problems with the clearing and settling of trades, as well as the holding of securities by local banks, agents and depositories. The less developed a country’s securities market is, the greater the likelihood of custody problems.

•

Interest Rate Risk. An increase in interest rates may cause the value of securities held by the Fund to decline. Fixed income securities with longer durations tend to be more sensitive to changes in interest rates, making them more volatile than securities with shorter durations or floating or adjustable interest rates. The negative impact on the Fund from potential interest rate increases could be swift and significant, including falling market values, increased redemptions and reduced liquidity. The 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. 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.

During periods of falling interest rates, an issuer of a callable security held by the Fund may “call” or repay the security before its stated maturity, which may result in the Fund having to reinvest the 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.

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. It is anticipated that LIBOR will be

11​

discontinued at the end of 2021, which 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.

•

Liquidity Risk. Liquidity risk exists when particular investments are difficult to purchase or sell. Certain investments may be subject to restrictions on resale, trade over-the-counter or in limited volume, or lack an active trading market. Accordingly, the Fund may not be able to sell or close out of such investments at favorable times or prices (or at all), or at the prices approximating those at which the Fund currently values them. Illiquid securities may trade at a discount from comparable, more liquid investments and may be subject to wide fluctuations in market value.

•

Real Estate Companies Risk. An investment in companies that invest in real estate (including REITs) exposes the Fund to the risks of the real estate market and the risks associated with the ownership of real estate. These risks can include fluctuations in the value of or destruction of underlying properties; realignment in tenant living and work habits (for example, movements to and from different parts of a nation, a region, a state or a city); tenant or borrower default; market saturation; changes in general and local economic conditions; decreases in market rates for rents; increases in vacancies; competition; property taxes; capital expenditures or operating expenses; other economic or political events affecting the real estate industry including interest rates and government regulation; concentration in a limited number of properties, geographic regions or property types; and low quality and/or conflicted management. Real estate is generally a less liquid asset class and companies that hold real estate may not be able to liquidate or modify their holdings quickly in response to changes in economic or other market conditions. Additionally, such companies may utilize leverage, which increases investment risk and the potential for more volatility in the Fund’s returns.

•

Small- and/or Mid-Capitalization Companies Risk. Small- and mid-capitalization companies may be more vulnerable to adverse general market or economic developments, and their securities may be less liquid and may experience greater price volatility than larger, more established companies.

•

Valuation Risk. Independent market quotations for certain investments held by the Fund may not be readily available, and such investments may be fair valued or valued by a pricing service at an evaluated price. These valuations involve subjectivity and

12

different market participants may assign different prices to the same investment. As a result, there is a risk that the Fund may not be able to sell an investment at the price assigned to the investment by the Fund. In addition, the value of the securities or other assets in the Fund’s portfolio may change on days or during time periods when shareholders will not be able to purchase or sell the Fund’s Shares.

•

Variable and Floating Rate Instruments Risk. 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. 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.

Performance Information

The bar chart that follows shows the annual total returns of the Fund for a full calendar year. The table that follows the bar chart shows the Fund’s average annual total returns, both before and after taxes. The bar chart and table provide an indication of the risks of investing in the Fund by comparing the Fund’s performance from year to year and by showing how the Fund’s average annual returns for one calendar year compared with its underlying index and another broad measure of market performance. The Barclays Capital U.S. Short Treasury Bond Index measures the performance of public obligations of the U.S. Treasury that have a remaining maturity of between 1 and 12 months.

All returns assume reinvestment of dividends and distributions. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Performance reflects fee waivers and/or expense reimbursement in effect, if such waivers or reimbursements were not in place, the Fund’s performance would be reduced. Fund performance current to the most recent month-end is available by calling 1-888-474-7725 or by visiting newyorklifeinvestments.com.

After-tax returns are calculated using the highest historical individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on your tax situation and may differ from those shown and are not relevant if you hold your Shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. In some cases the return after taxes may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund Shares at the end of the measurement period.

Investment Advisor

IndexIQ Advisors LLC is the investment advisor to the Fund.

14

Portfolio Manager

The professionals jointly and primarily responsible for the day-to-day management of the Fund are Greg Barrato and James Harrison. Mr. Barrato, Senior Vice President of the Advisor, has been a portfolio manager of the Fund since February 2011 and Mr. Harrison, Vice President of the Advisor, has been a portfolio manager of the Fund since April 2018.

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.

Tax Information

The Fund’s distributions are expected to 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. However, subsequent withdrawals from such a tax-advantaged account may be subject to U.S. federal income tax. 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.
