Summary Information

IQ Cleaner Transport ETF

In alignment with the National Wildlife Federation®‡

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 Candriam Cleaner Transport 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					0.45%
	Distribution and/or Service (12b-1) Fees					0.00%
	Other Expenses(a)					0.01%
	Total Annual Fund Operating Expenses					0.46%
	Expense Waiver/Reimbursement(b)					0.01%
	Total Annual Fund Operating Expenses After Waiver/Reimbursement					0.45%

(a)

The Fund has not yet commenced operations and Other Expenses are based on estimated amounts for the current fiscal year.

(b)

IndexIQ Advisors LLC (the “Advisor”) has contractually agreed to waive or reduce its management fee and/or reimburse expenses of the Fund in an amount that limits “Total Annual Fund Operating Expenses” (exclusive of interest, taxes, brokerage fees and commissions, dividends paid on short sales, acquired fund fees and expenses, and extraordinary expenses) to not more than 0.45% of the average daily net assets of the Fund. The agreement will remain in effect until August 31, 2022 unless terminated by the Board of Trustees of the Fund.

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.

‡

Shares of the Fund are not issued, sponsored or endorsed by the National Wildlife Federation®

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, 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
$46			$147

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities or other instruments. 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. This rate excludes the value of portfolio securities received or delivered as a result of in-kind creations or redemptions of the Shares. The Fund is newly organized and, as of the date of the Prospectus, has not yet commenced operations.

Principal Investment Strategies

The Fund employs a “passive management” — or indexing — investment approach designed to track the performance of the Underlying Index, which was developed by IndexIQ LLC (“IndexIQ”) with Candriam Belgium S.A. (“Candriam”) acting as index consultant to IndexIQ. The Underlying Index incorporates thematic selection criteria designed to provide exposure to equity securities of companies that support the transition to more environmentally efficient transportation technologies, such as electric vehicles, bicycles, motor vehicle parts manufacturers, and multi-passenger transportation. The Underlying Index includes companies engaged in renewable energy production, sustainable mining for battery resources, vehicle production and sustainable transportation infrastructure. Companies selected for inclusion in the Underlying Index offer, support or enable cleaner transportation products and services. A company included in the Underlying Index is not required to be primarily or even directly engaged in activities that protect or achieve cleaner transportation technologies. The Underlying Index includes thematic selection criteria developed by IndexIQ and Candriam that reflect initiatives, research and programs of the National Wildlife Federation (“NWF”), a 501(c)(3) public charity.

The Underlying Index includes securities of large-, mid- and small-capitalization companies that trade in the U.S. and foreign markets, including emerging markets other than China, Egypt, India, Kuwait, Pakistan, Qatar, Saudi Arabia and United Arab Emirates. The index universe consists of approximately the largest 99% of the free-float market capitalization in the global markets. As of September 30, 2021, the market capitalization range of the Underlying Index was approximately $1.0 billion to $1.8 trillion. As of September 30, 2021, the primary sectors within the Underlying Index are consumer discretionary, industrials and information technology.

The Underlying Index first applies developed and emerging market-specific screens to the initial universe to screen out companies that fail to meet certain minimum environmental, social and governance (ESG) criteria. The Underlying Index also includes an exclusionary screen based on any continued and significant non-compliance with the principles within the United Nation’s Global Compact as well as the exclusion of companies engaged in certain businesses beyond minimum thresholds (e.g., companies that operate in countries with oppressive regimes, that operate in adult content, alcohol, armament, gambling, nuclear, and tobacco, or that utilize animal testing or genetic modification in research and development).

Initial Developed Markets Screen

Companies included in the initial universe that trade in developed markets are given an overall ESG score based according to the following business activity and stakeholder criteria. Companies are scored relative to other companies within the same industry.

The business activity criteria (the “Business Activity Criteria”) are:

•

Climate Change: Activities related to the production of renewable energy and decarbonizing business activities.

•

Resources and Waste: Activities related to the efficient utilization of resources, recycling, and mitigating the impact on ecosystems.

•

Digitalization and Innovation: Activities that drive higher industrial and resource efficiencies and protecting data privacy and the resilience of digital networks.

•

Health and Wellness: Activities related to providing healthy products and services, improving air quality, and investing in human capital through job creation, gender equality and decent working conditions.

•

Demographic Shifts: Activities related to providing products and services to aging populations in developed countries and supporting population growth in emerging countries through investment in infrastructure and the food supply chain.

The stakeholder criteria (the “Stakeholder Criteria”) are:

•

Treatment of customers, including advertising practices, after sales service and support, and anti-competitive behaviors.

•

Treatment of employees, including working conditions, employee retention, gender equality, training and career opportunities.

•

Environmental initiatives and compliance with new environmental legislation.

•

Supplier standards and oversight, including supplier adherence to fair labor standards.

•

Corporate governance, including quality of governance and ethics, adherence to accounting standards and anti-bribery efforts.

•

Societal impact and how the company is viewed by populations in the area where the company operates.

Companies that score in the lowest 30% are excluded from the Underlying Index.

Initial Emerging Markets Screen

Companies included in the initial universe that trade in emerging markets are excluded from the Underlying Index if they do not satisfy certain Business Activity Criteria and Stakeholder Criteria or if a company’s majority shareholder is a state or government entity with poor environmental, social or governance related performance.

Thematic Screen

The thematic selection criteria used by the Underlying Index to identify and score companies for potential inclusion in the Index are:

•

Transportation Equipment and Services: Activities related to providing fuel-efficient, clean or shared vehicle production and services (including electric vehicles, rail, air and shipping).

•

Clean Energy: Activities related to supporting clean transportation technologies through producing renewable and reducing reliance on fossil fuels.

•

Enabling Technology: Activities related to providing technology, software and hardware that allow for the transformation to more efficient transportation and reduced energy consumption, such as semiconductors, navigation and maps software, and computer aided design software.

•

Sustainable Transportation Infrastructure: Activities relating to the manufacture of essential or infrastructure components of the sustainable transportation industry, such as batteries, charging stations and electric motors.

The Underlying Index applies a three-part scoring process to determine a company’s thematic score based on the following three scoring criteria:

•

Revenue: A company’s revenue score on a theme is generated based on: (1) the percentage of revenue that the company derives from activities relevant to the theme (companies that generate a higher percentage of revenue from relevant activities score higher); and (2) the amount of revenue that the company derives from activities related to the theme (companies that generate a greater amount of revenue from relevant activities score higher).

•

Materiality Score: A company’s materiality score on a theme is generated based on the materiality of the company’s business relative to the theme.

•

Impact Score: A company’s impact score on a theme is generated based on: (1) the company’s ability to benefit from the development of environmental technologies; (2) company’s impact on carbon emissions and climate change, including investments in low-carbon technologies, the use of low-carbon inputs, the development of products with low-carbon intensity, and general exposure of the company’s revenue, assets and capital expenditures to climate change; (3) the company’s ability to offer quality products with reduced risk of chemical pollution and toxic waste; and (4) the company’s management of natural resources in input materials and energy, products and waste.

The thematic score is determined based on the revenue, materiality and impact scores.

Following the application of the screens and exclusion criteria, the Underlying Index selects the top-ranked 50 to 80 companies for inclusion based on the thematic selection criteria scoring. The number of companies selected for inclusion in the Underlying Index will vary depending on the number of companies that exceed the minimum thematic screening score required for inclusion in the Underlying Index. The components are selected by starting with the securities with the highest score until either the total number of selected securities is 80, or the score of the next-ranked security fails to score above the minimum threshold. If there are less than 50 securities at the end of the process, the selection continues until at least 50 securities are selected in the Underlying Index.

Securities selected for inclusion in the Underlying Index are weighted using a modified market capitalization-weighting methodology, with a minimum component weight of 0.25% and maximum component weight of 3% at the time of rebalance.

The Underlying Index is rebalanced quarterly. The Underlying Index applies the exclusionary screen on a monthly basis and any company identified in the exclusionary screen is removed from the Underlying Index. 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.

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.

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.

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.

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.

Depositary Receipts Risk

Sponsored and unsponsored depositary receipts involve risk not experienced when investing directly in the equity securities of an issuer. Depositary receipts may be less liquid than the underlying shares in their primary trading market. Any distributions paid to the holders of depositary receipts are usually subject to a fee charged by the depositary. Holders of depositary receipts may have limited voting rights, and investment restrictions in certain countries may adversely impact the value of depositary receipts.

Emerging Markets Securities Risk

Securities of issuers based in countries with developing economies (emerging market countries) may present market, credit, currency, liquidity, legal, political and other risks different from, or greater than, the risks of investing in developed market countries and are generally considered speculative in nature. Emerging market countries are subject to greater market volatility, lower trading volume, political and economic instability, uncertainty regarding the existence of trading markets, rapid inflation, possible repatriation of investment income and capital, currency convertibility issues, less uniform accounting standards and more governmental limitations on foreign investment than more developed markets. Laws regarding foreign investment in emerging market securities, securities regulation, title to securities, and shareholder rights may change quickly and unpredictably. In addition, the enforcement of systems of taxation at federal, regional and local levels in emerging market countries may be inconsistent and subject to sudden change.

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.

Focused Investment Risk

To the extent that the 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.

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 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.

Foreign Securities Valuation Risk

The Fund’s value may be impacted by events that cause the fair value of foreign securities to materially change between the close of the local exchange on which they trade and the time at which the Fund prices its Shares. Additionally, because foreign exchanges on which securities held by the Fund may be open on days when the Fund does not price its Shares, the potential exists for the value of the securities in the Fund’s portfolio to change on days when shareholders will not be able to purchase or sell the Fund’s Shares. To the extent the Fund calculates its NAV based on fair value prices and the value of the Underlying Index is based on the securities’ closing price on foreign securities markets (i.e., the value of the Underlying Index is not based on fair value prices), the valuation of the Fund’s NAV may deviate from the calculation of the Underlying Index.

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.

Industry/Sector Concentration Risk.

The Fund’s investment of a large percentage of its assets in the securities of issuers within the same industry or sector means that an adverse economic, business or political development may affect the value of the Fund’s investments more than if the Fund were more broadly diversified. A concentration makes the Fund more susceptible to any single occurrence and may subject the Fund to greater market risk than a fund that is not so concentrated.

Consumer Discretionary Sector Risk.

Companies in the consumer discretionary sector may be adversely affected by, among other things, the performance of domestic and international economies, exchange and interest rates, worldwide demand, competition, consumer confidence, consumers’ disposable income levels, propensity to spend and consumer preferences, social trends and marketing campaigns.

Industrials Sector Risk.

Companies in the industrials sector may be affected by, among other things, worldwide economic growth, supply and demand for specific products and services, product obsolescence, environmental damages or product liability claims, rapid technological developments and government regulation. Government spending policies may impact the profitability of the industrials sector since industrials companies, especially aerospace and defense companies, often rely on government demand for their products and services.

Information Technology Sector Risk.

Companies in the information technology sector may be adversely affected by, among other things, domestic and international market competition, obsolescence due to rapid technological developments, new product introduction, unpredictable growth rates and competition for qualified personnel. Aggressive pricing and reduced profit margins, intellectual property rights protections, cyclical market patterns and evolving industry standards and government regulations may also impact information technology companies. The market prices of

information technology securities may exhibit a greater degree of market risk and more frequent, sharp price fluctuations than other types of securities. These securities may fall in and out of favor with investors rapidly, which may cause sudden selling and dramatically lower market prices.

Investment Style Risk

The Underlying Index seeks to allocate investment exposure based upon a particular style of investing. Different investment styles tend to shift in and out of favor depending upon market and economic conditions and investor sentiment. As a consequence, the Fund may underperform as compared to the market generally or to other funds that invest in similar asset classes but employ different investment styles. Further, there is no guarantee that the Underlying Index will accurately or optimally utilize the investment style or that it will successfully provide the desired investment exposure. The degree to which the Underlying Index accurately or optimally utilizes the investment style is dependent upon information and data that may be incomplete, inaccurate or unavailable, which could adversely affect the analysis of the factors relevant to a particular investment.

•

ESG Investing Style Risk. The Underlying Index seeks to provide exposure to the equity securities of companies meeting environmental, social and corporate governance investing criteria. The Underlying Index excludes or limits exposure to securities of certain issuers for non-financial reasons, and the Fund may forgo some market opportunities available to funds that do not use these criteria. The application of environmental, social and corporate governance investing criteria may affect the Fund’s exposure to certain sectors or types of investments and may impact the Fund’s relative investment performance depending on whether such sectors or investments are in or out of favor in the market. In addition, there is no guarantee that the construction methodology of the Underlying Index will accurately provide exposure to issuers meeting environmental, social and corporate governance criteria.

•

Cleaner Transport Investing Style. The returns on a portfolio of securities that excludes companies that have not adopted practices and policies to support the transition to more efficient transportation technologies may trail the returns on a portfolio of securities that includes companies that have not adopted these practices and policies. Investing only in a portfolio of securities of companies that help to achieve cleaner transportation may affect the Fund’s exposure to certain types of investments and may adversely impact the Fund’s performance depending on whether such investments are in or out of favor in the market.

Issuer Risk

The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Large-Capitalization Companies Risk

Large-capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large-capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large-capitalization companies has trailed the overall performance of the broader securities markets.

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 U.S. and world economies and markets, which may increase financial market volatility and have significant adverse direct or indirect effects on the 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.

New Fund Risk

The Fund is a new fund. As a new fund, there can be no assurance that it will grow to or maintain an economically viable size, in which case it could ultimately liquidate.

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 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 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 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.

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.

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.

Performance Information

As of the date of this Prospectus, the Fund has not yet completed a full calendar year of operations and therefore does not report its performance information. The Fund’s performance current to the most recent month-end is available by calling 1-888-474-7725 or by visiting newyorklifeinvestments.com.

Investment Advisor

IndexIQ Advisors LLC is the investment advisor to the Fund.

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 inception and Mr. Harrison, Vice President of the Advisor, has been a portfolio manager of the Fund since inception.

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.

The Fund is offered by IndexIQ, the Fund’s sponsor, in alignment with the National Wildlife Federation (“NWF”). The Fund is designed to promote investment objectives consistent with NWF’s mission. Shares of the Fund are not sponsored, endorsed or promoted by NWF, and NWF is not an investment adviser or service provider to the Fund. NWF makes no representations or warranties regarding the performance of the Fund and will have no obligation or liability in connection with the Fund. The Fund’s sponsor, IndexIQ, and its affiliates are supporters of and donors to NWF and are making a substantial contribution to NWF in connection with NWF’s agreement to license use of its name and trademarks to IndexIQ and its affiliates. NYLIM and IndexIQ’s contribution to NWF is calculated on an annualized basis to be the lower of: (i) 0.045% of the Fund’s average daily net managed assets (the average daily value of the total assets of the Fund, less all accrued liabilities of the Fund and less any management fees
