Portfolio Turnover [Text Block] oef_PortfolioTurnoverTextBlock
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.
Strategy [Heading] oef_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] oef_StrategyNarrativeTextBlock
To pursue its goal, the Fund normally invests at least 80% of its net assets in equity securities of companies that are tied economically to Japan, including other investment companies that provide investment exposure to such securities. The Fund considers a company to be tied economically to Japan if: (1) the issuer is organized under the laws of Japan or the issuer maintains its principal place of business in Japan; (2) the securities of the issuer are principally listed on Japan’s stock exchanges regardless of the country in which the issuer is organized; or (3) the issuer has at least 50% of its assets in Japan or derives 50% or more of its total revenue from goods and/or services produced or sold in Japan.
The Fund may hold securities of any market capitalization and in any sector. Equity securities include, but are not limited to, common stock, convertible and preferred stock, and exchange traded funds.
The Portfolio Managers seek to identify high-quality Japanese companies that appear to be positioned for durable growth. The Portfolio Managers will employ a research driven, bottom-up, fundamental approach to stock selection, with a long term perspective that combines both quantitative analysis and qualitative judgment in seeking to identify companies that the Portfolio Managers believe are attractive investment opportunities and have the potential to increase their corporate value. To gain a deep understanding of companies and their respective business environments, the Portfolio Managers may seek to directly and/or collaboratively engage with companies and industry organizations on issues related to, among others, capital management and corporate governance, in seeking to support management and their efforts to enhance shareholder value.
In seeking to achieve the Fund’s investment objective, the Portfolio Managers use the following three step investment process to identify a potential universe of securities for the Fund:

1.
Quantitative screening: The Portfolio Managers screen companies based on metrics such as return on equity and earnings before interest, taxes, depreciation, and amortization (“EBITDA”) margins, and further look for companies that they believe are priced lower than the Portfolio Managers’ estimate of their intrinsic value with identifiable reasons for the discount in an attempt to identify what they believe to be high quality companies;

2.
Qualitative business analysis: The Portfolio Managers analyze numerous factors, including but not limited to, management expertise, industry trends, and the strength of a product line or brand as they seek to identify companies that the Portfolio Managers believe have the most durable business models to position themselves for long-term sustainable growth, and have the greatest opportunities for potential value creation for all shareholders. The Portfolio Managers may also seek to engage directly with company management, when appropriate.

3.
Strategic valuation and analysis: The Portfolio Managers evaluate the valuation of the securities identified through the first two steps as they seek to identify high quality companies at attractive valuations.

The Portfolio Managers generate a score for each security in a “Watch List” generated from the above steps to quantify the following factors: (i) business fundamentals, (ii) governance, (iii) environment and social factors, (iv) engagement potential, and (iv) valuations. These scores are then aggregated to generate a single composite score for each security. From the Watch List, the Portfolio Managers seek to construct a well-diversified portfolio across economic sectors with securities selected based upon their proprietary score and an assessment of their risk exposures.
As part of their fundamental investment analysis the Portfolio Managers consider Environmental, Social and Governance (ESG) factors they believe are financially material to individual investments, where applicable. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the Portfolio Managers believe that the consideration of financially material ESG factors, alongside traditional financial metrics, may enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.
The Portfolio Managers may reduce or sell a security if they believe it is unattractively valued, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.
The Fund will not change its strategy of normally investing at least 80% of its net assets in equity securities of companies that are tied economically to Japan, including other investment companies that provide investment exposure to such securities, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.

Neuberger Berman Japan Equity ETF | Convertible Securities Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock Convertible Securities Risk. The value of a convertible security, which is a form of hybrid security (i.e., a security with both debt and equity characteristics), typically increases or decreases with the price of the underlying common stock. In general, a convertible security is subject to the market risks of stocks when the underlying stock’s price is high relative to the conversion price and is subject to the market risks of debt securities when the underlying stock’s price is low relative to the conversion price. The general market risks of debt securities that are common to convertible securities include, but are not limited to, interest rate risk and credit risk. Many convertible securities have credit ratings that are below investment grade and are subject to the same risks as an investment in lower-rated debt securities (commonly known as “junk bonds”). To the extent the Fund invests in convertible securities issued by small- or mid-cap companies, it will be subject to the risks of investing in such companies.
Neuberger Berman Japan Equity ETF | Currency Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

Neuberger Berman Japan Equity ETF | Authorized Participants Concentration Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock Authorized Participants Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants. To the extent they exit the business or are otherwise unable to proceed in creation and redemption transactions with the Fund and no other Authorized Participant is able to step forward to create or redeem, 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. Authorized Participant concentration risk may be heightened for ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that have lower trading volumes.
Neuberger Berman Japan Equity ETF | International Closed Market Trading Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock International Closed Market Trading Risk. To the extent the Fund’s investments trade in markets that are closed when the Fund and NYSE Arca, Inc. (“Exchange”) are open, there are likely to be deviations between current pricing of an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market). As a result, premiums or discounts to NAV may develop in share prices. In addition, shareholders may not be able to purchase or redeem their shares of the Fund, or purchase or sell shares of the Fund on the Exchange, on days when the NAV of the Fund could be significantly affected by events in the relevant non-U.S. markets.
Neuberger Berman Japan Equity ETF | Premium/Discount Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock 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.
Neuberger Berman Japan Equity ETF | Secondary Market Trading Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock 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 or that the Fund’s shares will continue to be listed.
Neuberger Berman Japan Equity ETF | Foreign Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock Foreign Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); imposition of economic sanctions against a particular country or countries, organizations, companies, entities and/or individuals; significant government involvement in an economy and/or market structure fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. World markets, or those in a particular region, may all react in similar fashion to important economic or political developments. In addition, foreign markets may perform differently than the U.S. markets. The effect of economic instability on specific foreign markets or issuers may be difficult to predict or evaluate. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations. Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.
Neuberger Berman Japan Equity ETF | Growth Stock Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock Growth Stock Risk. Because the prices of most growth stocks are based on future expectations, these stocks tend to be more sensitive than value stocks to bad economic news and negative earnings surprises. When these expectations are not met or decrease, the prices of these stocks may decline, sometimes sharply, even if earnings showed an absolute increase. Bad economic news or changing investor perceptions may adversely affect growth stocks across several sectors and industries simultaneously.

Neuberger Berman Japan Equity ETF | Japan Investment Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock Japan Investment Risk. The Japanese economy may be subject to economic, political and social instability, which could have an adverse effect on the Japanese securities held by the Fund. The Japanese market can experience significant volatility due to exchange rates, social, political, regulatory, economic or environmental events and natural disasters that may occur in Japan.The Japanese economy has only recently emerged from a prolonged economic downturn. Since the year 2000, Japan’s economic growth rate has remained relatively low. The Japanese economy is characterized by government intervention and protectionism, reliance on oil imports, an unstable financial services sector, relatively high unemployment, a highly regulated labor market, an aging demographic, declining population, and large government debt. As such, economic growth is heavily dependent on continued growth in international trade, relatively low commodities prices, government support of the financial services sector and other government policies. Japan is heavily dependent on oil and other commodity imports, and higher commodity prices could therefore have a negative impact on the Japanese economy. International trade, particularly with the U.S., also impacts the growth of the Japanese economy, and adverse economic conditions in the U.S. or other trade partners may affect Japan. The Japanese yen has fluctuated widely at times, and any increase in its value may cause a decline in exports that could weaken the Japanese economy. In addition, the yen has had a history of unpredictable and volatile movements against the U.S. dollar.Japan also has a growing economic relationship with China and other Southeast Asian countries, and thus Japan’s economy may also be affected by economic, political or social instability in those countries (whether resulting from local or global events). Other factors, such as the occurrence of natural disasters and relations with neighboring countries (including China, South Korea, North Korea and Russia), may also negatively impact the Japanese economy.
Neuberger Berman Japan Equity ETF | Large Shareholder Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock 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, and brokerage costs. Large redemptions could also result in tax consequences to shareholders and impact the Fund’s ability to implement its investment strategy.
Neuberger Berman Japan Equity ETF | Liquidity Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock 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.
Neuberger Berman Japan Equity ETF | Market Capitalization Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock Market Capitalization Risk. To the extent the Fund invests in 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, or by adverse publicity and investor perceptions.
Neuberger Berman Japan Equity ETF | Market Volatility Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock 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.

New funds may not attract sufficient assets to achieve investment, trading or other efficiencies and, if the Fund does not grow in size, it will be at greater risk than larger funds of wider bid-ask spreads for its shares, trading at a greater premium or discount to NAV and/or a stop to trading.

Risk [Text Block] oef_RiskTextBlock 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.
Neuberger Berman Japan Equity ETF | Preferred Securities Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock Preferred Securities Risk. Preferred securities, which are a form of hybrid security (i.e., a security with both debt and equity characteristics), may pay fixed or adjustable rates of return. Preferred securities are subject to issuer-specific and market risks applicable generally to equity securities, however, unlike common stocks, participation in the growth of an issuer may be limited. Distributions on preferred securities are generally payable at the discretion of the issuer’s board of directors and after the company makes required payments to holders of its debt securities. For this reason, preferred securities are subject to greater credit, interest, and liquidation risk than debt securities, and the value of preferred securities will usually react more strongly than debt securities to actual or perceived changes in the company’s financial condition or prospects. Preferred securities of smaller companies may be more vulnerable to adverse developments than preferred securities of larger companies. Preferred securities may be less liquid than common stocks.
Neuberger Berman Japan Equity ETF | Recent Market Conditions [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock Recent Market Conditions. Both U.S. and international markets have experienced significant volatility in recent months and 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.Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks raised interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase or start decreasing, the timing, frequency or magnitude of any such changes in interest rates, or when such changes might stop or 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, or reduce liquidity across various markets or decrease confidence in the markets.Some countries, including the U.S., have adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with trade negotiationsbetween the U.S. and China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, if the U.S. dollar continues to be strong, it may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.Regulators in the U.S. have proposed and adopted a number of changes to regulations involving the markets and issuers, some of which apply to the Fund. The full effect of various newly adopted regulations is not currently known. Additionally, it is not currently known whether any of the proposed regulations will be adopted. However, due to the scope of regulations being proposed and adopted, certain of these 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.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.There is widespread concern about the potential effects of global climate change 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 may negatively impact certain issuers and/or industries.

Risk [Text Block] oef_RiskTextBlock Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors.

Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

Risk [Text Block] oef_RiskTextBlock 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, 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. 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.

Risk [Text Block] oef_RiskTextBlock 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.
Neuberger Berman Japan Equity ETF | Valuation Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock 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.

[2] Neuberger Berman Investment Advisers LLC (“Manager”) has contractually undertaken to waive and/or reimburse certain fees and expenses of the Fund so that the total annual operating expenses (excluding interest, brokerage commissions, acquired fund fees and expenses, taxes including any expenses relating to tax reclaims, dividend and interest expenses relating to short sales, and extraordinary expenses, if any) (“Operating Expenses”) of the Fund are limited to 0.49% of average net assets until 8/31/2025 (after taking into account the Fee Waiver discussed in footnote 3 below) and 0.69% of average net assets from 9/1/2025 to 8/31/2027 and may not be terminated during its term without the consent of the Board of Trustees. The Fund has agreed that it will repay the Manager for fees and expenses waived or reimbursed for the Fund provided that repayment does not cause annual Operating Expenses to exceed the expense limitation in place at the time the fees were waived and/or the expenses were reimbursed, or the expense limitation in place at the time the Fund repays the Manager, whichever is lower. Any such repayment must be made within three years after the year in which the Manager incurred the expense.
