Summary Information

NYLIM Investment Grade CLO ETF
(prior to August 28, 2026, named NYLI Investment Grade CLO ETF)

Investment Objective

The NYLIM Investment Grade CLO ETF (the "Fund") seeks capital preservation and current income.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy, hold and sell 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.

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

(b)New York Life Investment Management LLC ("New York Life Investment" or "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 commissions, dividend payments on short sales, acquired fund fees and expenses, other expenditures which are capitalized in accordance with generally accepted accounting principles and other extraordinary expenses not incurred in the ordinary course of the Fund's business) to not more than 0.25% of the average daily net assets of the Fund. The agreement will remain in effect permanently 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. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell 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

3

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:

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. This rate excludes the value of the 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 this Prospectus, has not yet commenced operations.

Principal Investment Strategies

The Fund, under normal circumstances, invests at least 80% of the value of its assets (net assets plus the amount of any borrowings for investment purposes) in investment grade-rated debt tranches of collateralized loan obligations ("CLOs"). Investment grade CLO securities are rated BBB- and Baa3 or higher by a nationally recognized statistical rating organization ("NRSRO") or, if unrated, are judged to be of comparable quality by NYL Investors LLC (the "Subadvisor"). To the extent that the Fund utilizes derivatives that provide exposure to these investments or to one or more market risk factors associated with these investments, such derivatives will be counted towards the Fund's 80% investment policy. The Fund will not invest in any CLO debt securities rated below BB- and Ba3 or if unrated, determined to be of comparable credit quality by the Advisor and/or the Subadvisor. The Fund will not invest in any CLO equity securities.

CLO securities are typically issued by a trust or other special purpose entity and are backed by principal and interest payments from a pool of loans, which may include, domestic and non-U.S. senior secured loans, senior unsecured loans, and subordinate corporate loans. The loans and other assets within a CLO are selected by the CLO's manager. The loans and other assets within a CLO may be rated below investment grade or unrated and may be "covenant lite" (which have few or no financial maintenance covenants).

The Fund will only invest in CLOs with a minimum initial total offering size of $250 million. The Fund will not invest more than 10% of its net assets in any single tranche of a CLO. The Fund may invest in CLOs of any maturity. The Fund may purchase CLOs in both the primary market (i.e., directly from

4

arranging banks) and in the secondary market. The Fund may invest in floating-rate and fixed-rate CLOs but will not invest more than 10% of its assets in fixed-rate CLOs. The Fund may invest in privately issued securities.

The Fund will invest primarily in CLOs that are U.S. dollar denominated. However, the Fund may from time to time invest up to 30% of its net assets in CLOs that are denominated in foreign currencies. To the extent the Fund invests in non-U.S. dollar denominated securities, it may seek to hedge its exposure to foreign currency to U.S. dollars using currency forward contracts or futures contracts.

The Fund may invest up to 10% of its net assets in affiliated or non-affiliated exchange-traded products, including ETFs. The Fund may invest a portion of its assets in cash or other short-term instruments, such as money market instruments or money market funds. The Fund is classified as non-diversified under the Investment Company Act of 1940, as amended (the "1940 Act"). Therefore, the Fund may invest a greater amount of its assets in the securities of a single issuer or a small number of issuers than a diversified fund.

Investment Process

The Subadvisor's investment process seeks to identify CLO securities that offer attractive risk-adjusted returns, while seeking to preserve capital and generate current income. The Subadvisor's investment approach combines a top-down portfolio construction framework with a bottom-up security selection process:

•Top-Down Portfolio Construction: Portfolio allocations are guided by macroeconomic conditions, credit cycle outlook, and relative value opportunities across rating tiers and sectors. The Subadvisor integrates these views into portfolio positioning to balance income generation with capital preservation.

•Bottom-Up Security Analysis: The Subadvisor evaluates each potential investment using a comprehensive assessment of the CLO's structure and underlying collateral. Factors considered include collateral quality and diversity, manager performance and experience, structural protections, cash flow modeling under stress scenarios, and documentation review. The Subadvisor leverages its deep credit research capabilities to gain insight into the specific assets within a specific CLO.

•Risk Management: The Subadvisor actively monitors credit, liquidity, and structural risks at both the security and portfolio levels. Portfolio exposures are regularly reviewed to ensure alignment with the Fund's investment objective.

5

The Subadvisor may sell a security if it no longer believes the security will contribute to meeting the investment objective of the Fund. In considering whether to sell a security, the Subadvisor may evaluate, among other things, the condition of the economy and meaningful changes in the issuer's financial condition.

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.

Asset-Backed Securities Risk

Asset-backed securities are securities that represent interests in, and whose values and payments are based on, a "pool" of underlying assets, which may include, among others, lower-rated debt securities and corporate loans, consumer loans or mortgages and leases of property. Asset-backed securities include collateralized debt obligations, collateralized bond obligations, and collateralized loan obligations and other similarly structured vehicles. As with other debt securities, asset-backed securities are subject to credit risk, extension risk, interest rate risk, liquidity risk and valuation risk. The impairment of the value of collateral or other assets underlying an asset-backed security, such as a result of non-payment of loans or non-performance of underlying assets, may result in a reduction in the value of such asset-backed securities and losses to the Fund.

Investments in mortgage-related securities make an investor more susceptible to adverse economic, interest rate, political or regulatory events that affect the value of real estate. Mortgage-related securities are also significantly affected by the rate of prepayments. Impairment of the underlying obligations or collateral, such as by non-payment, will reduce a mortgage-related security's value.

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.

6

Cash Transactions Risk

The Fund currently intends to effect creations and redemptions principally for cash, rather than for in-kind securities. For this reason, the Fund may be required to sell portfolio securities in order to obtain the cash needed to distribute redemption proceeds. The Fund may recognize a capital gain on these sales that might not have been incurred if the Fund had made a redemption in-kind. This may decrease the tax efficiency of the Fund compared to ETFs that utilize an in-kind redemption process.

CLO Manager Risk

CLOs are managed by investment advisers independent of the Advisor and the Subadvisor. CLO managers are responsible for selecting, managing and replacing the underlying bank loans within a CLO. CLO managers may have limited operating histories, may be subject to conflicts of interests, including managing the assets of other clients or other investment vehicles, or receiving fees that incentivize maximizing the yield, and indirectly the risk, of a CLO. Adverse developments with respect to a CLO manager, such as personnel and resource constraints, regulatory issues or other developments that may impact the ability and/or performance of the CLO manager, may adversely impact the performance of the CLO securities in which the Fund invests.

Collateralized Loan Obligations Risk

Collateralized loan obligations ("CLOs") are asset-backed securities whose underlying collateral is a pool of loans, which may include, among others, floating rate and fixed rate senior secured loans, senior unsecured loans, and subordinate corporate loans, including loans that may be rated below investment grade. CLOs are subject to the risk that distributions from the collateral may not be adequate to make interest or other payments, the quality of the collateral may decline in value or default, or the Fund may invest in tranches of CLOs that are subordinate to other tranches. CLOs also carry risks including, but not limited to, interest rate risk and credit risk. The degree of such risks will generally depend on the type of collateral securities and the specific tranche in which the Fund is invested. CLOs issue classes or "tranches" of debt that vary in risk and yield and may experience substantial losses due to actual defaults, decrease of market value due to collateral defaults and exhaustion of subordinate tranches, market anticipation of defaults or investor aversion to CLO securities as a class.

The risks of investing in CLOs depend largely on the tranche invested in and the type of the underlying loans in the tranche of the CLO in which the Fund invests. Subordinate tranche investments involve greater risk of loss than more senior tranches. To the extent that the Fund invests in unrated CLO tranches, the Fund's ability to achieve its investment objective will be more dependent on the Subadvisor's credit analysis than would be the case when the Fund invests in rated CLO tranches.

7

Covenant Lite Loan Risk

Some of the loans in which an underlying CLO may invest and to which the Fund may indirectly be exposed to may be covenant lite, which means the loans or obligations contain fewer financial maintenance covenants than other loans or obligations (in some cases, none) and do not include terms which allow the lender to monitor the borrower's performance and declare a default if certain criteria are breached. An investment by the Fund in a CLO holding this type of loan may potentially hinder the ability to reprice credit risk associated with the CLO. As a result of this risk, the Fund's exposure to losses may be increased, which could result in an adverse impact on the Fund's net income and NAV.

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.

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.

8

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.

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. A counterparty to a derivatives transaction with the Fund may be unable or unwilling to make timely principal, interest, settlement or margin payments, fulfill the delivery conditions of the contract or transaction, or otherwise honor its obligations. If a counterparty fails to meet its contractual obligations the Fund will have contractual remedies pursuant to the agreements related to the transaction, but the Fund may be unable to terminate or realize any gain on the investment or transaction, resulting in a loss to the Fund. The Fund may experience significant delays in obtaining any recovery in an insolvency, bankruptcy, or other reorganization proceeding involving a counterparty (including recovery of any collateral posted by it) and may obtain limited or no recovery in such circumstances.

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

9

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 effects of leverage may also cause the Fund to liquidate portfolio positions when it would not be advantageous to do so. In general, 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.

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. Federal law prohibits the Fund from acquiring investment company shares, including shares of other registered investment companies (including ETFs), in excess of specific thresholds unless exempted by rule, regulation or exemptive order. These prohibitions may prevent the Fund from allocating its investment in an optimal manner.

Extended Settlement Risk

Newly issued CLO securities purchased in the primary market typically experience delayed or extended settlement periods, possibly longer than seven days. In the period following such a purchase and prior to settlement these CLO securities may be considered less liquid than similar CLOs available in the secondary market. In such circumstances the Fund bears a risk of loss if the value of the CLO declines before the settlement date or if the Fund is required to sell the CLO security prior to settlement. There is also the risk that the security will not be issued or that the counterparty will not meet its obligation, resulting in a loss of the investment opportunity.

Foreign Currency Forward Contracts Risk

When trading in foreign currency forward contracts, the Fund will contract with a foreign or domestic bank, or a foreign or domestic securities dealer, to make or take future delivery of a specified amount of a particular currency. There are no limitations on daily price moves in such forward contracts, and banks and dealers are not required to continue to make markets in such contracts. Governmental imposition of credit controls might limit any such forward contract trading. Foreign currency forward contracts involve certain risks, including the risk of failure of the counterparty to perform its obligations under the contract and the risk that the use of forward contracts

10

may not serve as a complete hedge because of an imperfect correlation between movements in the prices of the contracts and the prices of the currencies hedged.

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. 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 clearing, custody and trade settlement problems.

Futures Contracts Risk

Futures contracts are typically exchange-traded contracts that call for the future delivery of an asset at a certain price and date, or cash settlement of the terms of the contract. There may be an imperfect correlation between the changes in market value of the securities held by the Fund and the prices of futures contracts. There may not be a liquid secondary market for the futures contracts and the Fund may not be able to enter into a closing transaction. Exchanges may also limit the number of positions that can be held or controlled by the Fund, thus limiting the ability of the Fund to implement its investment strategy. Futures markets are highly volatile and the use of futures may increase the Fund's volatility. The value of an investment in the Fund may change quickly and without warning.

High Yield Securities Risk

Investments in high yield or below investment grade securities (commonly referred to as "junk bonds") are considered speculative by certain ratings agencies because investments in such securities present a greater risk of loss than investments in higher quality securities. Such securities may, under certain circumstances, be less liquid than higher rated securities. These securities pay investors a premium (a high interest rate or yield) because of

11

the potential illiquidity and increased risk of loss (which may be substantial or total loss) of income and principal. These securities can also be subject to greater price volatility. In times of unusual or adverse market, economic or political conditions, these securities may experience higher than normal default rates.

Income Risk

The Fund's income may decline when interest rates fall or if there are defaults in its portfolio. This decline can occur because the 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 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.

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.

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.

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.

12

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.

Money Market/Short-Term Securities Risk

To the extent the Fund holds cash or invests in money market or short-term securities, the Fund may be less likely to achieve its investment objective. In addition, it is possible that the Fund's investments in these instruments could lose money.

New Fund Risk

As a new fund, there can be no assurance that the Fund will grow to or maintain an economically viable size. Like other new funds, large inflows and outflows may impact the 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.

Newly Issued Securities Risk

The credit obligations in which the Fund invests may include newly issued securities, or "new issues," such as initial debt offerings. New issues may have a magnified impact on the performance of the Fund during periods in which it has a small asset base. The impact of new issues on the Fund's performance likely will decrease as the Fund's asset size increases, which could reduce the Fund's returns. New issues may not be consistently available to the Fund for investing, particularly as the Fund's asset base grows. Certain new issues, such as initial debt offerings, may be volatile in price due to the absence of a prior trading market, limited quantities available for trading and limited information about the issuer. The Fund may hold new issues for a short period of time. This may increase the Fund's portfolio turnover and may lead to increased expenses for the Fund, such

13

as transaction costs. In addition, new issues can experience an immediate drop in value after issuance if the demand for the securities does not continue to support the offering price.

Non-Diversified Risk

The Fund is classified as a "non-diversified" investment company under the 1940 Act, which means it may invest a larger percentage of its assets in a smaller number of issuers than a diversified fund. To the extent the Fund invests its assets in a smaller number of issuers, the Fund will be more susceptible to negative events affecting those issuers than a diversified fund.

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.

Portfolio Management Risk

The Fund is subject to portfolio management risk because it is an actively managed portfolio. In managing the Fund's investment portfolio, the portfolio managers will apply investment techniques and risk analyses that may not produce the desired result or, while it may be the desired result, may underperform other types of investment strategies. There can be no guarantee that the Fund will meet its investment objective(s).

Private Placement and Restricted Securities Risk

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 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. The trading of Shares on securities exchanges is subject to the risk of irregular trading activity. 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

14

fail to attract a large number of shareholders. Pursuant to an exchange's "circuit breaker" rules, trading in the Fund's Shares may be halted due to extraordinary market volatility. 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.

Trading Price Risk

Although it is generally expected that the market price of the Fund's Shares will approximate the Fund's NAV, there may be times when the market price and the NAV vary significantly. 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 market supply of and demand for Shares and the Fund's NAV, among other reasons. As a result, the trading prices of the Fund's Shares may deviate significantly from NAV during periods of market volatility. The market price of the Fund's Shares during the trading day, like the price of any exchange-traded security, includes a "bid/ask" spread charged by 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. The risk of wide bid and ask spreads may be especially pronounced for smaller funds. In addition, increased market volatility may cause wider spreads.

Valuation Risk

When valuing the Fund's portfolio investments, if a market quotation is readily available for a portfolio investment, that investment will generally be valued at the market value. However, unlike publicly traded securities that trade on national securities exchanges, there is no central place or exchange for trading most debt securities and thus readily available market quotations are unavailable. Debt securities generally trade on an "over-the-counter" market. Due to the lack of centralized information and trading, and variations in lot sizes of certain debt securities, the valuation of debt securities may carry more uncertainty and risk than that of publicly traded securities. Debt securities are commonly valued by third-party pricing service providers that utilize 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. However, because the available information is less reliable and more subjective, elements of judgment

15

may play a greater role in valuation of debt securities than for other types of securities. Additionally, pricing service providers generally price debt securities assuming orderly transactions of an institutional "round lot" size, but some trades may occur in smaller, "odd lot" sizes, often at lower prices than institutional round lot trades. Valuing the Fund's investments using fair value pricing provided by pricing service providers will result in prices that may differ from current market valuations and that may not be the prices at which those investments could have been sold during the period in which the particular fair values were used. It is possible that the fair value determined for a portfolio instrument may be materially different from the value that could be realized upon the sale of that instrument.

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.

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 its market price rather than its 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 nylim.com/etf.

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.
