GOAL

The Fund seeks long-term growth of capital and income generation.

Fees and Expenses

These tables below describe the fees and expenses that you may pay if you buy, hold and sell shares of the Fund ("Shares"). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below.  

Shareholder Fees (fees paid directly from your investment)	None
Annual Fund Operating Expenses (expenses that you pay each year as a % of the value of your investment)
Management fees	0.50
Other expenses	0.08
Acquired fund fees and expenses	0.01
Total annual operating expenses	0.59
Fee waivers and/or expense reimbursement	0.02
Total annual operating expenses after fee waivers and/or expense reimbursement1	0.57

Expense Example

The expense example can help you compare costs among funds. The example assumes that you invested $10,000 for the periods shown, that you redeemed all of your shares at the end of those periods, that the Fund earned a hypothetical 5% total return each year, and that the Fund's expenses were those in the table. Actual performance and expenses may be higher or lower. 

1 Year	3 Years	5 Years	10 Years
$58	$183	$323	$732

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 Fund shares are held in a taxable account. These costs, which are not reflected in annual operating expenses or in the example, affect the Fund's performance. During the most recent fiscal year the Fund's portfolio turnover rate was 112% of the average value of its portfolio.

Principal Investment Strategies

The Fund seeks to achieve its goal primarily through a strategy of writing collateralized put options on U.S. indices, including the S&P 500® Index and other indices in the S&P 500® suite of indices, and exchange traded funds ("ETFs"). The Fund attempts to generate returns through the receipt of option premiums from selling puts, as well as through investments in fixed income instruments, which collectively are intended to reduce volatility relative to what it would be if the Fund held the underlying equity index on which the options are written. The Fund's investments in fixed income instruments may be of any duration, may include variable and floating rate instruments, and may include U.S. Treasury securities and other securities issued by the U.S. government and its agencies and instrumentalities, debt securities issued by corporations or trust entities, cash and cash

equivalents, structured notes, mortgage-backed securities and asset-backed securities. The Fund also may invest in money market mutual funds and ETFs.

In a put writing strategy, the Fund (as the seller of the option) receives premiums from the purchaser of the option in exchange for providing the purchaser with the right to sell the underlying instrument to the Fund at a specific price (i.e., the strike price). If the market price of the instrument underlying the option exceeds the strike price, it is anticipated that the option would go unexercised and the Fund would earn the full premium upon the option's expiration or a portion of the premium upon the option's early termination. If the market price of the instrument underlying the option drops below the strike price, it is anticipated that the option would be exercised and the Fund would pay the option buyer the difference between the market value of the underlying instrument and the strike price.

As an example, it is anticipated when the Fund writes a put option on the S&P 500 Index at a specific strike price and the S&P 500 goes above that strike price and the option is not exercised (i.e., in a rising market), the premium collected may be less than the S&P 500's gains depending on the amount of the premium and the S&P 500's gains. Conversely, it is anticipated when the Fund writes a put option on the S&P 500 Index at a specific strike price and the S&P 500 goes below that strike price and the option is exercised (i.e., in a falling market), the premium collected may offset all or a portion of the S&P 500's losses depending on the amount of the premium and the S&P 500's losses. Finally, it is anticipated when the Fund writes a put option on the S&P 500 Index at a specific strike price and the S&P 500 stays at that strike price and the option is not exercised (i.e., in a flat market), the Fund would keep the premium collected.

The Portfolio Managers will select option investments based on their estimate of current and future market volatility levels, underlying instrument valuations and perceived market risks. Further, the Portfolio Managers will evaluate relative option premiums in determining preferred option contract terms, such as strike prices and expiration dates.

At the time of writing (selling) a put option, the aggregate investment exposure, as measured on a notional basis (i.e., the value of the underlying instrument at its strike price), of the options written by the Fund will generally be equal to 100% of the Fund's total assets. The Fund's aggregate investment exposure, as measured on a notional basis, may be greater than 100% of the Fund's total assets from time to time but it will not exceed 125% of its total assets.

The Fund's fixed income instruments will be primarily investment grade and are intended to provide liquidity and preserve capital and will serve as collateral for the Fund's investments in options. The Fund considers fixed income instruments to be investment grade if, at the time of investment, they are rated within the four highest categories by at least one independent credit rating agency or, if unrated, are determined by the Portfolio Managers to be of comparable quality. The premiums received by the Fund for writing options will generally be invested in fixed income instruments, money market mutual funds and ETFs in order to seek to partially offset any liabilities the Fund incurs from writing options. Because the Fund will use options to gain exposure to the equity markets, and because options will not require the Fund to deposit the full notional amount of the investment, the Fund will also invest a significant amount of its total assets in fixed income instruments, money market mutual funds and ETFs. Its investments in options generally will not constitute a significant amount of its total assets, however, the aggregate investment exposure of its investments in options, as discussed above, generally will be equal to 100% of its total assets.

The Fund may invest in both American-style and European-style options as well as FLexible EXchange® Options (FLEX Options). The Fund may purchase and write call options on securities and indices, including writing (selling) both covered (i.e., where the Fund holds an equivalent position in the instrument underlying the option) and uncovered calls (i.e., where the Fund does not own the instrument underlying the option and must purchase the underlying instrument to meet its call obligations). The Fund may also purchase put options, including purchasing puts on security indices and put spreads on indices (i.e., buying and selling an equal number of puts on the same index with differing strike prices or expiration dates).

In an effort to achieve its goal, the Fund may engage in active and frequent trading.

PRINCIPAL INVESTMENT RISKS

Most of the Fund's performance depends on what happens in equity, fixed income and options markets, the Portfolio Managers' evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund's investment strategies. The Fund's use of derivative instruments will result in leverage, which amplifies the risks that are associated with these markets. The markets' behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal.

The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers' evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis and valuation.

The Fund is not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund's performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

Call Risk. Upon the issuer's desire to call a security, or under other circumstances where a security is called, which may happen for a number of reasons, such as declining interest rates or changes in credit spreads, the issuer can opt to repay the obligation underlying a "callable security" early. When this occurs, the Fund may have to reinvest the proceeds in an investment offering a lower yield or with a higher risk of default and may not realize the full anticipated benefit from such investment.

Credit Risk. Credit risk is the risk that issuers, guarantors, or insurers may fail, or become less able or unwilling to pay interest and/or principal when due. Changes in the actual or perceived creditworthiness of an issuer or a downgrade or default affecting any of the Fund's securities could affect the Fund's performance by affecting the credit quality or value of the Fund's securities. Generally, the longer the maturity and the lower the credit quality of a security, the more sensitive it is to credit risk.

Derivatives Risk. Use of derivatives, such as options, is a highly specialized activity that can involve investment techniques, analysis and risks different from, and in some respects greater than, those associated with investing in more traditional investments, such as stocks and bonds. Derivatives can be highly complex and highly volatile and may perform in unanticipated ways. Derivatives can create leverage, and the Fund could lose more than the amount it invests; some derivatives can have the potential for unlimited losses. Derivatives may at times be highly illiquid, and the Fund may not be able to close out or sell a derivative at a particular time or at an anticipated price. Derivatives can be difficult to value and valuation may be more difficult in times of market turmoil. The value of a derivative instrument depends largely on (and is derived from) the value of the reference instrument underlying the derivative. There may be imperfect correlation between the behavior of a derivative and that of the reference instrument underlying the derivative. An abrupt change in the price of a reference instrument could render a derivative worthless. Derivatives may involve risks different from, and possibly greater than, the risks associated with investing directly in the reference instrument. Suitable derivatives may not be available in all circumstances, and there can be no assurance that the Fund will use derivatives to reduce exposure to other risks when that might have been beneficial. Derivatives involve counterparty risk, which is the risk that the other party to the derivative will fail to make required payments or otherwise comply with the terms of the derivative. That risk is generally thought to be greater with over-the-counter (OTC) derivatives than with derivatives that are exchange traded or centrally cleared. When the Fund uses derivatives, it will likely be required to provide margin or collateral; these practices are intended to satisfy contractual undertakings and regulatory requirements and will not prevent the Fund from incurring losses on derivatives. The need to provide margin or collateral could limit the Fund's ability to pursue other opportunities as they arise. Ongoing changes to regulation of the derivatives markets and actual and potential changes in the regulation of funds using derivative instruments could limit the Fund's ability to pursue its investment strategies. New regulation of derivatives may make them more costly, or may otherwise adversely affect their liquidity, value or performance.

Additional risks associated with certain types of derivatives are discussed below:

Options. The use of options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. If a strategy is applied at an inappropriate time or market conditions or trends are judged incorrectly, the use of options may lower the Fund's return. There can be no guarantee that the use of options will increase the Fund's return or income. In addition, there may be an imperfect correlation between the movement in prices of options and the securities underlying them and there may at times not be a liquid secondary market for various options. An abrupt change in the price of an underlying security could render an option worthless. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, or in interest or currency exchange rates, including the anticipated volatility of the underlying instrument (known as implied volatility), which in turn are affected by the performance of the issuer of the underlying instrument, by fiscal and monetary policies and by national and international political and economic events. As such, prior to the exercise or expiration of the option, the Fund is exposed to implied volatility risk, meaning the value, as based on implied

volatility, of an option may increase due to market and economic conditions or views based on the sector or industry in which issuers of the underlying instrument participate, including company-specific factors.

By writing put options, the Fund takes on the risk of declines in the value of the underlying instrument, including the possibility of a loss up to the entire strike price of each option it sells, but without the corresponding opportunity to benefit from potential increases in the value of the underlying instrument. When the Fund writes a put option, it assumes the risk that it must purchase the underlying instrument at a strike price that may be higher than the market price of the instrument. If there is a broad market decline and the Fund is not able to close out its written put options, it may result in substantial losses to the Fund. By writing a call option, the Fund may be obligated to deliver instruments underlying an option at less than the market price. In the case of an uncovered call option, there is a risk of unlimited loss. When an uncovered call is exercised, the Fund must purchase the underlying instrument to meet its call obligations and the necessary instruments may be unavailable for purchase. Additionally, volatility in the market for equity securities, which has been dramatically increased recently for certain stocks, can meaningfully increase the risk of loss associated with options. When the Fund writes a covered call option, it gives up the opportunity to profit from a price increase in the underlying instrument above the strike price. If a covered call option that the Fund has written is exercised, the Fund will experience a gain or loss from the sale of the underlying instrument, depending on the price at which the Fund purchased the instrument and the strike price of the option. The Fund will receive a premium from writing options, but the premium received may not be sufficient to offset any losses sustained from exercised options. In the case of a covered call, the premium received may be offset by a decline in the market value of the underlying instrument during the option period. If an option that the Fund has purchased is never exercised or closed out, the Fund will lose the amount of the premium it paid and the use of those funds.

ETF Risk. As an exchange-traded fund ("ETF"), the Fund is subject to the following risks:

Authorized Participants Concentration Risk. The Fund has a limited number of financial institutions that may act as authorized participants. Only an authorized participant may transact in creation and redemption transactions directly with the Fund, and authorized participants are not obligated to engage in such transactions. To the extent they exit the business or are otherwise unable or unwilling to proceed in creation and redemption transactions with the Fund, such as in times of market stress, and no other Authorized Participant is able to step forward to create or redeem, trading in Fund shares may be significantly diminished, bid-ask spreads may widen and shares of the Fund may be more likely to trade at a premium or discount to net asset value ("NAV") and possibly face trading halts or delisting. To the extent the Fund invests in securities issued by non-U.S. issuers or other securities or instruments that have lower trading volumes, this risk is heightened.

Cash Transactions Risk. Unlike certain ETFs, the Fund may effect its creations and redemptions in cash or partially in cash. As a result, an investment in the Fund may be less tax-efficient than an investment in other ETFs. Other ETFs generally are able to make in-kind redemptions and avoid realizing gains in connection with transactions designed to raise cash to meet redemption requests. If the Fund effects a portion of redemptions for cash, it may be required to sell portfolio securities in order to obtain the cash needed to distribute redemption proceeds, which also involves transaction costs. If the Fund recognizes gain on these sales, this generally will cause the Fund to recognize gain it might not otherwise have recognized if it were to distribute portfolio securities in-kind, or to recognize such gain sooner than would otherwise be required. The Fund generally intends to distribute these gains to shareholders to avoid being taxed on this gain at the Fund level and otherwise comply with the special tax rules that apply to it. This strategy may cause shareholders to be subject to tax on gains they would not otherwise be subject to, or at an earlier date than, if they had made an investment in a different ETF. In addition, cash transactions may have to be carried out over several days if the securities market in which the Fund is trading is less liquid and may involve considerable transaction expenses and taxes. These brokerage fees and taxes, which will be higher than if the Fund sold and redeemed its shares principally in-kind, may be passed on to purchasers and redeemers of shares in the form of transaction fees. However, the Fund has capped the total transaction fees that may be charged in connection with redemptions. To the extent any costs associated with cash transactions are not offset by any transaction fees payable by an authorized participant, the Fund's performance could be negatively impacted.

Premium/Discount Risk. There may be times when the market price of the Fund's shares is more than the NAV intra-day (at a premium) or less than the NAV intra-day (at a discount). As a result, shareholders of the Fund may pay more than NAV when purchasing shares and receive less than NAV when selling Fund shares. This risk is heightened in times of market volatility or periods of steep market declines. In such market conditions, market or stop loss orders to sell Fund shares may be executed at prices well below NAV.

Secondary Market Trading Risk. Investors buying or selling shares in the secondary market will normally pay brokerage commissions, which are often a fixed amount and may be a significant proportional cost for investors buying or selling relatively small amounts of shares. Secondary market trading is subject to bid-ask spreads, which is the difference between the highest price a buyer is willing to pay to purchase shares of a fund (bid) and the lowest price a seller is willing to accept for shares (ask) when buying or selling shares in the secondary market, and trading in Fund shares may be halted by the Exchange because of market conditions or other reasons. If a trading halt occurs, a shareholder may temporarily be unable to purchase or sell shares of the Fund. The bid-ask spread, which varies over time, is generally narrower if the Fund has more trading volume and market liquidity and wider if the Fund has less trading volume and market liquidity. In addition, the bid-ask spread can be affected by the liquidity of the Fund's underlying investments and can widen if the Fund's underlying investments become less liquid or illiquid. In addition, although the Fund's shares are listed on the Exchange, there can be no assurance that an active trading market for shares will develop or be maintained, that bid-ask spreads will be narrow, or that the Fund's shares will continue to be listed.

High Portfolio Turnover Risk. The Fund may engage in active and frequent trading and may have a high portfolio turnover rate, which may increase the Fund's transaction costs, may adversely affect the Fund's performance and may generate a greater amount of capital gain distributions to shareholders than if the Fund had a low portfolio turnover rate.

Interest Rate Risk. In general, the value of investments with interest rate risk, such as debt securities, will move in the direction opposite to movements in interest rates. If interest rates rise, the value of such securities may decline. Typically, the longer the maturity or duration of a debt security, the greater the effect a change in interest rates could have on the security's price. Thus, the sensitivity of the Fund's debt securities to interest rate risk will increase with any increase in the duration of those securities.

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

Large Shareholder Risk. Certain large shareholders, including Authorized Participants, may from time to time own a substantial amount of the Fund's shares. There is no requirement that these shareholders maintain their investment in the Fund. There is a risk that such large shareholders or that the Fund's shareholders generally may redeem all or a substantial portion of their investments in the Fund in a short period of time, which could have a significant negative impact on the Fund's NAV, liquidity, brokerage costs, and expenses. Large redemptions could also result in tax consequences to shareholders and impact the Fund's ability to implement its investment strategy.

Leverage Risk. Leverage amplifies changes in the Fund's net asset value and may make the Fund more volatile. Derivatives may create leverage and can result in losses to the Fund that exceed the amount originally invested and may accelerate the rate of losses or magnify the risks of other portfolio investments. There can be no assurance that the Fund's use of any leverage will be successful and the Fund may need to dispose of some of its holdings at unfavorable times or prices. The Fund's investment exposure can exceed its net assets, sometimes by a significant amount.

Liquidity Risk. From time to time, the trading market for a particular investment in which the Fund invests, or a particular type of instrument in which the Fund is invested, may become less liquid or even illiquid. Illiquid investments frequently can be more difficult to purchase or sell at an advantageous price or time, and there is a greater risk that the investments may not be sold for the price at which the Fund is carrying them. Certain investments that were liquid when the Fund purchased them may become illiquid, sometimes abruptly. Additionally, market closures due to holidays or other factors may render a security or group of securities (e.g., securities tied to a particular country or geographic region) illiquid for a period of time. An inability to sell a portfolio position can adversely affect the Fund's value or prevent the Fund from being able to take advantage of other investment opportunities. Market prices for such securities or other investments may be volatile. During periods of substantial market volatility, an investment or even an entire market segment may become illiquid, sometimes abruptly, which can adversely affect the Fund's ability to limit losses.

Unexpected episodes of illiquidity, including due to market or political factors, instrument or issuer-specific factors and/or unanticipated outflows or other factors, may limit the Fund's ability to pay redemption proceeds within the allowable time period. To meet redemption requests during periods of illiquidity, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.

Market Capitalization Risk. To the extent the Fund gains exposure to securities of small-, mid-, or large-cap companies, it takes on the associated risks. At times, any of these market capitalizations may be out of favor with investors. Compared to small- and mid-cap companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to large-cap companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings and limited product lines, markets

or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, by adverse publicity and investor perceptions, by interest rate changes and by government regulation.

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

Model Risk. To a significant extent, the Fund's performance will depend on the success of implementing and managing the investment models that assist in allocating the Fund's assets. Models that have been formulated on the basis of past market data may not be indicative of future price movements. Models rely on data inputs and such data may be incorrect or incomplete making the model unreliable. Models may not be reliable or produce unexpected results if unusual or disruptive events cause market moves the nature or size of which are inconsistent with the historic performance of individual markets and their relationship to one another or to other macroeconomic events. Models also may have hidden biases or exposure to broad structural or sentiment shifts. In the event that actual events fail to conform to the assumptions underlying such models, losses could be incurred. The performance of the investment models may be impacted by software or other technology malfunctions, programming inaccuracies, and similar circumstances.

Mortgage- and Asset-Backed Securities Risk. The value of mortgage- and asset-backed securities, including collateralized mortgage instruments, will be influenced by the factors affecting the housing market or the assets underlying the securities. These securities tend to be more sensitive to changes in interest rates than other types of debt securities. In addition, investments in mortgage- and asset-backed securities may be subject to prepayment risk and extension risk, call risk, credit risk, valuation risk, and illiquid investment risk, sometimes to a higher degree than various other types of debt securities. These securities are also subject to the risk of default on the underlying mortgages or assets, particularly during periods of market downturn, and an unexpectedly high rate of defaults on the underlying assets will adversely affect the security's value.

Other Investment Company Risk. To the extent the Fund invests in other investment companies, including money market funds and exchange-traded funds (ETFs), its performance will be affected by the performance of those other investment companies. Investments in other investment companies are subject to the risks of the other investment companies' investments, as well as to the other investment companies' expenses.

An ETF may trade in the secondary market at a price below the value of its underlying portfolio, may not be liquid and may be halted by the listing exchange. An actively managed ETF's performance will reflect its adviser's ability to make investment decisions that are suited to achieving the ETF's investment objectives. A passively managed ETF may not replicate the performance of the index it intends to track.

Prepayment and Extension Risk. The Fund's performance could be affected if borrowers pay back principal on certain debt securities, such as mortgage- or asset-backed securities, before (prepayment) or after (extension) the market anticipates such payments, shortening or lengthening their duration. Due to a decline in interest rates or an excess in cash flow into the issuer, a debt security might be called or otherwise converted, prepaid or redeemed before maturity. As a result of prepayment, the Fund may have to reinvest the proceeds in an investment offering a lower yield, may not benefit from any increase in value that might otherwise result from declining interest rates, and may lose any premium it paid to acquire the security. Conversely, rising market interest rates generally result in slower payoffs or extensions, which effectively increases the duration of certain debt securities, heightening interest rate risk and increasing the magnitude of any resulting price declines.

Recent Market Conditions. Both U.S. and international markets have experienced significant volatility in recent years. As a result of such volatility, investment returns may fluctuate significantly. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing or changing, which may impact such economies and markets in ways that cannot be foreseen at this time.

Some countries, including the U.S., have adopted more protectionist trade policies, which is a trend that appears to be continuing globally. Slowing global economic growth, the rise in protectionist trade policies, inflationary pressures, changes to some major international trade and security agreements, risks associated with the trade and security agreement between countries and regions,

including the U.S. and other foreign nations, political or economic dysfunction within some countries or regions, including the U.S., and dramatic changes in consumer sentiment, commodity prices and currency values could affect the economies and markets of many nations, including the U.S., in ways that cannot necessarily be foreseen at the present time and may create significant volatility in the markets. In addition, these policies, including the impact on the U.S. dollar, may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

The Federal Reserve and certain foreign central banks have started to lower interest rates, though economic or other factors, such as inflation, could stop such changes. It is difficult to accurately predict the pace at which interest rates might change, the timing, frequency or magnitude of any such changes in interest rates, or when such changes might stop or again reverse course. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected changes in interest rates could lead to significant market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility, reduce liquidity across various markets or decrease confidence in the markets.

Regulators in the U.S. have adopted a number of changes to regulations involving the markets and issuers, some of which apply to the Fund. The full effect of such regulations is not currently known and certain changes to regulation could limit the Fund's ability to pursue its investment strategies or make certain investments, may make it more costly for it to operate, or adversely impact performance. Additionally, it is possible that such regulations could be further revised or rescinded, which creates material uncertainty on their impact to the Fund.

Advancements in technology, including advanced development and increased regulation of artificial intelligence, may adversely impact market movements and liquidity. As artificial intelligence is used more widely, which can occur relatively rapidly, the profitability and growth of certain issuers and industries may be negatively impacted in ways that cannot be foreseen and could adversely impact its performance.

Tensions, war, or open conflict between nations, such as between Russia and Ukraine, in the Middle East, or in eastern Asia could affect the economies of many nations, including the United States. The duration of ongoing hostilities and any sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty. There is no assurance that the U.S. Congress will act to raise the nation's debt ceiling; a failure to do so could cause market turmoil and substantial investment risks that cannot now be fully predicted. Unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy.

Global climate change can have potential effects on property and security values. Certain issuers, industries and regions may be adversely affected by the impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change, including any direct or indirect consequences that may not be foreseen, may negatively impact certain issuers, industries and regions.

Return of Capital Risk. The Fund expects to make monthly distributions regardless of its performance and seeks to maintain relatively stable monthly distributions although the income earned by the Fund might vary from month-to-month. As a result, all or a portion of such distributions may represent a return of capital for tax purposes. A return of capital is generally tax-free to the extent of a shareholder's basis in the Fund's shares and reduces the shareholder's basis in their shares and results in a higher capital gain or lower capital loss when the shares on which the return of capital distribution was received are sold. After a shareholder's basis in the shares has been reduced to zero, return of capital distributions will be treated as gain from the sale of the shareholder's shares. The Fund's return of capital distributions are not derived from the net income or earnings and profits of the Fund. Shareholders should not assume that the source of distributions is from the net profits of the Fund. The character of the Fund's distributions may change from month-to-month and there is no guarantee that they will be similar in the future.

Structured Note Risk. Structured notes are notes where the principal and/or interest is determined by reference to the performance of a specific asset, benchmark asset, financial instrument, market or interest rate. Generally, investments in such notes are used as a substitute for positions in underlying indicators and involve many of the same risks associated with a direct investment in the underlying indicator the notes seek to replicate. Structured notes may be exchange traded or traded over-the-counter and privately negotiated. Structured notes can have risks of both fixed income securities and derivatives transactions,

including leverage risk. The interest and/or principal payments that may be made on a structured note may vary widely, depending on a variety of factors, including changes in the value of one or more specified reference instruments. The performance of structured notes will not replicate exactly the performance of the underlying indicator that the notes seek to replicate due to transaction costs and other expenses. In addition, there may be a lag between a change in the value of the underlying indicator and the value of the structured note. Structured notes are subject to counterparty risk, which is the risk that the issuer of the structured note will not fulfill its contractual obligation to complete the transaction with the Fund. Investments in structured notes, including credit-linked notes, involve risks including interest rate risk, credit risk, liquidity risk and market risk. Structured notes may be illiquid and may have a limited trading market, making it difficult to value them or sell them at an acceptable price.

U.S. Government Securities Risk. Although the Fund may hold securities that carry U.S. government guarantees, these guarantees do not extend to shares of the Fund itself and do not guarantee the market prices, including due to changes in interest rates, of the securities. Furthermore, not all securities issued by the U.S. government and its agencies and instrumentalities are backed by the full faith and credit of the U.S. Treasury. Securities not backed by the full faith and credit of the U.S. Treasury carry at least some risk of non-payment or default.

Variable and Floating Rate Instruments Risk. The market prices of instruments with variable and floating interest rates are generally less sensitive to interest rate changes than are the market prices of instruments with fixed interest rates. Variable and floating rate instruments may decline in value if market interest rates or interest rates paid by such instruments do not move as expected. Certain types of floating rate instruments, such as interests in bank loans, may be subject to greater liquidity risk than other debt securities, may have restrictions on resale and may lack an active market.

A summary of the Fund's additional principal investment risks is as follows:

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, processing and communications errors, counterparty and third-party disruptions or errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality, including those related to critical functions. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other operational risks that may affect the Fund or to develop processes and controls to completely eliminate or mitigate their occurrence or effects. Most issuers in which the Fund invests are heavily dependent on computers for data storage and operations, and require ready access to the internet to conduct their business. Thus, cybersecurity incidents could also affect issuers of securities in which the Fund invests, leading to significant loss of value.

Artificial Intelligence. The Fund and its service providers, including its adviser, may utilize artificial intelligence ("AI") technologies, including machine learning models and generative AI, to improve operational efficiency and in connection with research. In addition, counterparties used by the Fund may utilize AI in their business activities. While the Manager may restrict certain uses of AI tools, the Fund and its adviser are not in a position to control the use of AI in third-party products or services. The use of AI introduces numerous potential challenges and the use of AI can lead to reputational damage, legal liabilities, and competitive disadvantages, as well as negatively impact business operations, which may occur with or without mismanagement in the use of the AI. AI requires the collection and processing of substantial amounts of data, which poses risks of data inaccuracies, incompleteness, and inherent biases, and which can degrade the technology's effectiveness and reliability. Such data can include proprietary information, the use of which by AI may be unauthorized and subject to potential liability. Rapid technological advancements further complicate risk predictions, and competitors who adopt AI more swiftly may gain a competitive edge. The complexity and opacity of AI systems raise significant accountability and ethical concerns. AI has enhanced the ability of threat actors to amplify the potency, scale, and speed of cybersecurity attacks. AI's role in increasing automation raises concerns about job displacement and may lead to economic and social disruptions. The unpredictable nature of AI's impact on market dynamics complicates traditional risk assessment models, making it challenging to identify risks and opportunities using historical data. Legal and regulatory frameworks governing AI's use, particularly concerning data privacy and protection, are evolving rapidly. These changes could materially alter how AI is used, which may negatively impact the Fund.

Risk Management. Risk is an essential part of investing. No risk management program can eliminate the Fund's exposure to adverse events; at best, it may only reduce the possibility that the Fund will be affected by such events, and especially those risks that are not intrinsic to the Fund's investment program. The Fund could experience losses if judgments about risk prove to be incorrect.

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment's most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. The Fund's ability to value its investments in an accurate and timely manner may be impacted by technological issues and/or errors by third party service providers, such as pricing services or accounting agents.

PERFORMANCE

The following bar chart and table provide an indication of the risks of investing in the Fund. The Fund commenced operations after the assets of another investment company, Neuberger Berman U.S. Equity Index PutWrite Strategy Fund (the predecessor fund), were transferred to the Fund in a tax-free reorganization as of the close of business on January 26, 2024. The Fund has adopted the performance history of its predecessor fund. The information shown below prior to January 26, 2024 is for the predecessor fund. The bar chart shows how the Fund's performance has varied from year to year. The table below the bar chart shows what the returns would equal if you averaged out actual performance over various lengths of time and compares the returns with the returns of a broad-based market index and additional indices. The broad-based market index is required by regulation. The additional index or indices have characteristics relevant to the Fund's investment strategy. The indices are described in "Descriptions of Indices" in the prospectus.

Returns would have been lower if the Manager had not reimbursed certain expenses and/or waived a portion of the investment management fees, including those of the predecessor fund, during certain of the periods shown.

While the Fund's shares would have substantially similar annual returns to the Institutional Class shares of the predecessor mutual fund, their performance may differ from that shown because the Fund has lower expenses than the predecessor fund's Institutional Class shares. Performance for the Fund's Shares has not been adjusted to reflect the Fund's Shares' lower expenses than those of the predecessor fund's Institutional Class shares. Performance for the predecessor fund is based on the NAV per share of the predecessor fund shares rather than on market-determined prices.

INVESTMENT MANAGER

Neuberger Berman Investment Advisers LLC ("NBIA" or the "Manager") is the Fund's investment manager.

PORTFOLIO MANAGERS

The Fund is managed by Derek Devens, CFA (Managing Director of NBIA), Rory Ewing (Managing Director of NBIA) and Eric Zhou (Senior Vice President of NBIA). Mr. Devens joined the firm in 2016 and has managed the Fund since its inception in 2016, and Mr. Ewing joined the firm in 2016 and has been an Associate Portfolio Manager of the Fund since February 2019. Mr. Zhou joined the firm in 2016 and has been an Associate Portfolio Manager of the Fund since February 2022.

Buying and Selling Shares

The Fund issues and redeems Shares at its NAV only in a large specified number of Shares each called a "Creation Unit," or multiples thereof, and only with authorized participants who have entered into contractual arrangements with the Fund's distributor.

Individual Shares (rather than Creation Units) of the Fund may only be purchased and sold on a national securities exchange through a broker or dealer at market price and most investors will buy and sell Shares of the Fund on such an exchange. These transactions do not involve the Fund. The prices at which individual Shares may be purchased and sold on a national securities exchange through brokers are based on market prices and, because Shares will trade at market prices rather than at NAV, individual Shares of the Fund may trade at a price greater than or less than NAV. Shares of the Fund are listed on NYSE Arca, Inc.

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 (ask) when buying or selling Shares in the secondary market (the "bid-ask spread"). Most investors will incur customary brokerage commissions and charges when buying and selling shares of the Fund through a broker/dealer.

Recent information, including information about the Fund's NAV, market price, premiums and discounts, and bid-ask spreads, is included on the Fund's website at www.nb.com/ETF.

Tax Information

Unless you invest in the Fund through a tax-advantaged retirement plan or account or are a tax-exempt investor, you will be subject to tax on Fund distributions to you of ordinary income and/or net capital gains. Those distributions generally are not taxable to such a plan or account or a tax-exempt investor, although withdrawals from certain retirement plans and accounts generally are subject to federal income tax.

Payments to Investment Providers and Other Financial Intermediaries

If you purchase shares of the Fund through a broker/dealer or other financial intermediary, such as a bank, brokerage firm, workplace retirement program, or financial adviser (who may be affiliated with the Manager), the Fund and/or Neuberger Berman BD LLC and/or its affiliates may pay the intermediary for the sale of Fund shares and related services. These payments may create

a conflict of interest by influencing the broker/dealer or other financial intermediary and its employees to recommend the Fund over another investment. Ask your financial intermediary or visit its website for more information.
