Global X China Consumer ETF

Objective, Primary [Text Block]

rr_ObjectivePrimaryTextBlock

The Global X China Consumer ETF (“Fund”) seeks to provide investment results that correspond generally to the price and yield performance, before fees and expenses, of the Solactive China Consumer Total Return Index (“Underlying Index”).

Expense Narrative [Text Block]

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 the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund also invests at least 80% of its total assets in securities of consumer companies that are economically tied to China. For purposes of this policy, consumer companies include those engaged in producing or selling goods or services to consumers. Examples include producers of food, beverages, apparel, household and leisure goods, cars and related items, media content, operators of retail stores, and companies offering services to private consumers. The Fund’s 80% investment policies are non-fundamental and require 60 days’ prior written notice to shareholders before they can be changed. The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is designed to measure the equity performance of the investable universe of companies in the consumer sector of the Chinese economy, as defined by Solactive AG, the provider of the Underlying Index ("Index Provider"). In order to be eligible for inclusion in the Underlying Index, a company must have legal domicile and/or main business operations in China and primary business operations in the consumer sector. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 30, 2016, the Underlying Index was concentrated in the Consumer Discretionary and Consumer Staples sectors.

Portfolio Turnover [Text Block]

rr_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 Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 22.19% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

Strategy Portfolio Concentration [Text]

rr_StrategyPortfolioConcentration

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 30, 2016, the Underlying Index was concentrated in the Energy and Utilities sectors.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds section of the Prospectus and in the Statement of Additional Information ("SAI").

Asian Economic Risk: Decreasing Asian imports, new trade regulations, changes in exchange rates, a recession in Asia or a slowing of economic growth in this region could have an adverse impact on the Chinese economy.

Asset Class Risk: Securities in the Underlying Index or otherwise held in the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Assets Under Management (AUM) Risk: From time to time an Authorized Participant, a third party investor, the Fund’s adviser or another affiliate of the Fund’s adviser or the Fund may invest in the Fund and hold its investment for a specific period of time in order to facilitate commencement of the Fund’s operations or for the Fund to achieve size or scale. There can be no assurance that any such entity would not redeem its investment or that the size of the Fund would be maintained at such levels which could negatively impact the Fund.

Authorized Participant Concentration Risk: The Fund has a limited number of financial institutions that may act as Authorized Participants. Only Authorized Participants who have entered into agreements with the Fund’s distributor may engage in creation or redemption transactions directly with the Fund. To the extent that those Authorized Participants exit the business or are unable to process creation and/or redemption orders, and no other Authorized Participant is able to step forward to create or redeem in either of those cases, Shares may be more likely to trade at a premium or discount to NAV, and possibly face trading halts and/or delisting from an exchange. The Authorized Participant Concentration Risk may be heightened because the Fund invests in non-U.S. securities.

Concentration Risk: Because the Fund's investments are concentrated in Chinese securities and in the energy and utilities sectors, the Fund will be susceptible to loss due to adverse occurrences affecting this country and sectors. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in China, Risks Related to Investing in the Energy Sector, and Risks Related to Investing in the Utilities Sector.

Currency Risk: Because the Fund's NAV is determined in U.S. dollars, the Fund's NAV could decline if China's currency depreciates against the U.S. dollar or if there are delays or limits on repatriation of such currency. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the Fund's NAV may change quickly and without warning, which could have a significant negative impact on the Fund.

Custody Risk: Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Cyber Security Risk: Failures or breaches of the electronic systems of the Fund, the Adviser, and the Fund's other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions and negatively impact the Fund's business operations, potentially resulting in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherit limitations in such plans and systems. Furthermore, the Fund cannot control the cyber security plans and systems of the Fund's service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Emerging Market Risk: China is an emerging market country, which may be subject to a greater risk of loss than investments in developed markets. Securities markets of emerging market countries are less liquid, subject to greater price volatility, have smaller market capitalizations, have less government regulation, and are not subject to as extensive and frequent accounting, financial, and other reporting requirements as the securities markets of more developed countries.

Equity Securities Risk: Equity securities are subject to changes in value and their values may be more volatile than other asset classes, as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions.

European Economic Risk: Decreasing European Imports, new trade regulations, changes in exchange rates, a recession in Europe, or a slowing of economic growth in this region could have an adverse impact on the securities in which the Fund invests.

Foreign Securities Risk: The Fund's investments in foreign securities can be riskier than U.S. securities investments. Investments in the securities of foreign issuers (including investments in ADRs and GDRs) are subject to the risks associated with investing in those foreign markets, such as heightened risks of inflation or nationalization. The prices of foreign securities and the prices of U.S. securities have, at times, moved in opposite directions. In addition, securities of foreign issuers may lose value due to political, economic and geographic events affecting a foreign issuer or market. During periods of social, political or economic instability in a country or region, the value of a foreign security traded on U.S. exchanges, nonetheless, could be affected by, among other things, increasing price volatility, illiquidity, or the closure of the primary market on which the security (or the security underlying the ADR or GDR) is traded. You may lose money due to political, economic and geographic events affecting a foreign issuer or market.

Geographic Risk: A natural or other disaster could occur in China, which could affect the economy or particular business operations of companies economically tied to China, causing an adverse impact on the Fund's investments in China. China is located in a part of the world that has historically been prone to natural disasters such as floods, droughts, earthquakes, typhoons or tsunamis, and is economically sensitive to environmental events.

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

International Closed Market Trading Risk: To the extent that the underlying securities held by the Fund trade on foreign exchanges that may be closed when the securities exchange on which the Fund’s Shares trade is open, there are likely to be deviations between the current price of such an underlying security and the last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market). These deviations could result in premiums or discounts to the Fund’s NAV that may be greater than those experienced by other exchange-traded funds.

Investable Universe of Companies Risk: The investable universe of companies in which the Fund may invest may be limited. If a company no longer meets the Index Provider’s criteria for inclusion in the Underlying Index, the Fund may need to reduce or eliminate its holdings in that company. The reduction or elimination of the Fund’s holdings in the company may have an adverse impact on the liquidity of the Fund’s overall portfolio holdings and on Fund performance.

Issuer Risk: Fund performance depends on the performance of individual companies in which the Fund invests. Changes to the financial condition of any of those companies may cause the value of their securities to decline.

Large-Capitalization Companies Risk: Large-capitalization companies may trail the returns of the overall stock market. Large-capitalization stocks tend to go through cycles of doing better - or worse - than the stock market in general. These periods have, in the past, lasted for as long as several years.

Management Risk: The Fund is subject to the risk that the Adviser’s investment management strategy may cause the Fund to underperform the market or its relevant benchmark or adversely affect the ability of the Fund to achieve its investment objective.

Market Risk: Turbulence in the financial markets and reduced liquidity may negatively affect issuers, which could have an adverse effect on the Fund. In addition, there is a risk that policy changes by the U.S. Government, Federal Reserve, or other government actors, which could include increasing interest rates, could cause increased volatility in financial markets and lead to higher levels of Fund redemptions, which could have a negative impact on the Fund. The Fund’s NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk: The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Mid-Capitalization Companies Risk: Mid-capitalization companies may have greater price volatility, lower trading volume and less liquidity than large-capitalization companies. In addition, mid-capitalization companies may have have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than large-capitalization companies.

Nationalization Risk: Investments in China may be subject to loss due to expropriation or nationalization of assets and property or the imposition of restrictions on foreign investments and repatriation of capital.

Non-Diversification Risk: The Fund is classified as a “non-diversified” investment company under the Investment Company Act of 1940 ("1940 Act"). As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Operational Risk: The Fund is exposed to operational risk 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 the Adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate for those risks that they are intended to address.

Passive Investment Risk: The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Fund’s return to be lower than if the Fund employed an active strategy.

Premium/Discount Risk: Disruptions to creations and redemptions, the existence of extreme market volatility or potential lack of an active trading market for Shares may result in Shares trading at a significant premium or discount to NAV. If a shareholder purchases Shares at a time when the market price is at a premium to the NAV or sells Shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses.

Privatization Risk: China has privatized, or has begun the process of privatizing, certain entities and industries. Privatized entities may lose money or be re-nationalized.

Reliance on Trading Partners Risk: The Fund invests in the Chinese economy, which is heavily dependent upon trading with key partners. Any reduction in this trading, including as a result of adverse economic conditions in a trading partner’s economy, may cause an adverse impact on the Chinese economy in which the Fund invests. Through its portfolio companies' trading partners, the Fund is specifically exposed to Asian Economic Risk, European Economic Risk, and U.S. Economic Risk.

Risks Related to Investing in China: Investment exposure to China subjects the Fund to risks specific to China. China may be subject to considerable degrees of economic, political and social instability. China is an emerging market and demonstrates significantly higher volatility from time to time in comparison to developed markets. Over the past 25 years, the Chinese government has undertaken reform of economic and market practices and expansion of the sphere for private ownership of property in China. However, Chinese markets generally continue to experience inefficiency, volatility and pricing anomalies resulting from governmental influence, a lack of publicly available information and/or political and social instability. Internal social unrest or confrontations with other neighboring countries, including military conflicts in response to such events, may also disrupt economic development in China and result in a greater risk of currency fluctuations, currency convertibility, interest rate fluctuations and higher rates of inflation. Export growth continues to be a major driver of China’s rapid economic growth. Reduction in spending on Chinese products and services, institution of tariffs or other trade barriers, or a downturn in any of the economies of China’s key trading partners may have an adverse impact on the Chinese economy. The recent presidential election in the U.S. may have increased the probability of new trade regulations and other protective trade measures being implemented in relation to China. While policy implications remain uncertain, new regulations or trade barriers could lead to a decrease in trade activity between China and the U.S., which could have an adverse impact on the Chinese economy. China has implemented a number of tax reforms in recent years, and may amend or revise its existing tax laws and/or procedures in the future, possibly with retroactive effect. Changes in applicable Chinese tax law could reduce the after-tax profits of the Fund, directly or indirectly, including by reducing the after-tax profits of companies in China in which the Fund invests. Uncertainties in Chinese tax rules could result in unexpected tax liabilities for the Fund.

Risks Related to Investing in the Energy Sector: The value of securities issued by companies in the energy sector may decline for many reasons, including, without limitation, changes in energy prices; international politics; energy conservation; the success of exploration projects; natural disasters or other catastrophes; changes in exchange rates, interest rates, or economic conditions; changes in demand for energy products and services; and tax and other government regulatory policies.

Risks Related to Investing in the Utilities Sector: Companies in the utilities sector may be adversely affected by changes in exchange rates, domestic and international competition and governmental regulations on rates charged to customers. Privatization in the utilities sector may subject companies to greater competition and losses in profitability. Companies in the utilities industry may have difficulty obtaining an adequate return on invested capital, raising capital, or financing large construction programs during periods of inflation or unsettled capital markets. In addition, companies in the utilities sector may be adversely affected due to increase in fuel and operating costs and the costs of complying with regulations.

Tracking Error Risk: Tracking error is the divergence of the Fund's performance from that of the Underlying Index. Tracking error may occur because of differences between the securities and other instruments held in the Fund's portfolio and those included in the Underlying Index, pricing differences (including differences between a security's price at the local market close and the Fund's valuation of a security at the time of calculation of the Fund's NAV), differences in transaction costs, the Fund's holding of uninvested cash, differences in timing of the accrual of or the valuation of dividends or interest, tax gains or losses, changes to the Underlying Index or the costs to the Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unsual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not. Index ETFs that are track indices with significant weight in emerging markets issuers may experience higher tracking error other than other index ETFs that do not track such indices.

Trading Halt Risk: An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

U.S. Economic Risk: A decrease in U.S. imports, new trade regulations, changes in the U.S. dollar exchange rates or an economic slowdown in the United States may have an adverse impact on China's economy and, as a result, securities to which the Fund has exposure.

Valuation Risk: The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

Risk Nondiversified Status [Text]

rr_RiskNondiversifiedStatus

Non-Diversification Risk: The Fund is classified as a “non-diversified” investment company under the Investment Company Act of 1940 ("1940 Act"). As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests at least 80% of its total assets in the securities of the Underlying Index and in American Depositary Receipts ("ADRs") and Global Depositary Receipts ("GDRs") based on the securities in the Underlying Index. The Fund also invests at least 80% of its total assets in securities of financials companies that are economically tied to China. For purposes of this policy, financials companies include those engaged in banking, lending, insurance, investments and/or financing. The Fund’s 80% investment policies are non-fundamental and require 60 days’ prior written notice to shareholders before they can be changed.

The Underlying Index is designed to measure the equity performance of the investable universe of companies in the financials sector of the Chinese economy, as defined by Solactive AG, the provider of the Underlying Index ("Index Provider"). In order to be eligible for inclusion in the Underlying Index, a company must have legal domicile and/or main business operations in China and primary business operations in the financials sector. The Fund’s investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Adviser uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 30, 2016, the Underlying Index was concentrated in the Financials sector.

Portfolio Turnover [Text Block]

rr_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 Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 14.08% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

Strategy Portfolio Concentration [Text]

rr_StrategyPortfolioConcentration

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 30, 2016, the Underlying Index was concentrated in the Industrials sector.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in the Additional Information About the Funds section of the Prospectus and in the Statement of Additional Information ("SAI").

Asian Economic Risk: Decreasing Asian imports, new trade regulations, changes in exchange rates, a recession in Asia or a slowing of economic growth in this region could have an adverse impact on the Chinese economy.

Asset Class Risk: Securities in the Underlying Index or otherwise held in the Fund's portfolio may underperform in comparison to the general securities markets or other asset classes.

Assets Under Management (AUM) Risk: From time to time an Authorized Participant, a third party investor, the Fund’s adviser or another affiliate of the Fund’s adviser or the Fund may invest in the Fund and hold its investment for a specific period of time in order to facilitate commencement of the Fund’s operations or for the Fund to achieve size or scale. There can be no assurance that any such entity would not redeem its investment or that the size of the Fund would be maintained at such levels which could negatively impact the Fund.

Authorized Participant Concentration Risk: The Fund has a limited number of financial institutions that may act as Authorized Participants. Only Authorized Participants who have entered into agreements with the Fund’s distributor may engage in creation or redemption transactions directly with the Fund. To the extent that those Authorized Participants exit the business or are unable to process creation and/or redemption orders, and no other Authorized Participant is able to step forward to create or redeem in either of those cases, Shares may be more likely to trade at a premium or discount to NAV, and possibly face trading halts and/or delisting from an exchange. The Authorized Participant Concentration Risk may be heightened because the Fund invests in non-U.S. securities.

Concentration Risk: Because the Fund's investments are concentrated in Chinese securities and in the industrials sector, the Fund will be susceptible to loss due to adverse occurrences affecting this country and sector. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in China and Risks Related to Investing in the Industrials Sector.
