Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Underlying Index is designed to reflect the price fluctuation and performance of the China A share market and is composed of the 300 largest and most liquid stocks in the China A share market. The Underlying Index includes small-cap, mid-cap, and large-cap stocks. The Fund, using a “passive” or indexing investment approach, attempts to approximate the investment performance of 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 be 95% or better. A figure of 100% would indicate perfect correlation. A shares are equity securities issued by companies incorporated in mainland China and are denominated and traded in renminbi (“RMB”) on the Shenzhen and Shanghai Stock Exchanges. Subject to minor exceptions, under current regulations in the People’s Republic of China (“China” or the “PRC”), foreign investors can invest in the domestic PRC securities market only through certain foreign institutional investors that have obtained status as a Qualified Foreign Institutional Investor (“QFII”) or a Renminbi Qualified Foreign Institutional Investor (“RQFII”) from the China Securities Regulatory Commission (“CSRC”) and have been granted a specific aggregate dollar amount investment quota by the China’s State Administration of Foreign Exchange (“SAFE”) to invest foreign freely convertible currencies (in the case of a QFII) and RMB (in the case of a RQFII) in the PRC for the purpose of investing in the PRC’s domestic securities markets. The Sub-Adviser expects to obtain a RQFII license and to be granted, on behalf of the Fund, an estimated initial RQFII quota of $700 million. The Sub-Adviser, on behalf of the Fund, may invest in A shares and other permitted China securities listed on the Shanghai and Shenzhen Stock Exchanges up to the specified quota amount. The Sub-Adviser may apply for an increase of the initial RQFII quota if it uses the initial quota in its entirety. The Sub-Adviser expects to use a full replication indexing strategy to seek to track the Underlying Index. As such, the Sub-Adviser expects to invest directly in the component securities (or a substantial number of the component securities) of the Underlying Index in substantially the same weightings in which they are represented in the Underlying Index. If it is not possible for the Sub-Adviser to acquire component securities due to limited availability or regulatory restrictions, the Sub-Adviser may use a representative sampling indexing strategy to seek to track the Underlying Index instead of a full replication indexing strategy. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index when the Sub-Adviser is using a representative sampling indexing strategy. The Fund will normally invest at least 80% of its total assets in securities of issuers that comprise the Underlying Index. While the Fund intends to invest primarily and directly in A shares, the Fund also may invest in securities of issuers not included in the Underlying Index, swap contracts and other types of derivative instruments, and other pooled investment vehicles that the Adviser and/or Sub-Adviser believes will help the Fund to achieve its investment objective. The remainder of the Fund’s assets will be invested primarily in money market instruments and cash equivalents. Under normal circumstances, the Fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in Chinese securities. Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to the extent that its Underlying Index is concentrated. As of December 31, 2012, the Underlying Index is concentrated in the financial services sector. The Fund will also have significant exposure to the Basic Materials and Industrials sectors.

Risk [Heading]	rr_RiskHeading	Summary of Principal Risks
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. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective, as well as numerous other risks that are described in greater detail in the section of the Prospectus entitled “Further Discussion of Principal Risks” and in the Statement of Additional Information (“SAI”). Special Risk Considerations Relating to the RQFII Regime and Investments in A Shares. The Adviser’s ability to achieve its investment objective by investing in the component securities of the Underlying Index is dependent on the continuous availability of A shares and the Sub-Adviser’s ability to obtain additional RQFII quota on behalf of the Fund. If the Sub-Adviser’s RQFII quota is or becomes inadequate to meet the investment needs of the Fund or if the Sub-Adviser is unable to maintain its RQFII status, the Adviser and/or Sub-Adviser may seek to gain exposure to the A shares market by investing in securities not included in the Underlying Index, swaps and other derivative instruments, and other pooled investment vehicles that provide exposure to the A shares market until additional RQFII quota can be obtained. A reduction in or elimination of the RQFII quota may not only adversely affect the ability of the Fund to invest directly in A shares, but also the willingness of swap counterparties to engage in swaps and the performance of pooled investment vehicles linked to the performance of A shares. Therefore, any such reduction or elimination may have a material adverse effect on the ability of the Fund to achieve its investment objective. These risks are compounded by the fact that at present there are only a limited number of firms and counterparties that have QFII or RQFII status or are otherwise able to obtain A shares quota. In addition, the RQFII quota may be reduced or revoked by the Chinese regulators if, among other things, the Sub-Adviser fails to observe SAFE and other applicable Chinese regulations, which could also lead to other adverse consequences, including the requirement that the Fund dispose of its A shares holdings. If the Fund is unable to obtain sufficient exposure to the performance of the Underlying Index due to the limited availability of RQFII quota or other investments that provide exposure to the performance of A shares, the Fund could, among other actions, suspend creations until the Sub-Adviser determines that the requisite exposure to the Underlying Index is obtainable. During the period that creations are suspended, the Fund could trade at a significant premium or discount to the NAV and could experience substantial redemptions. Alternatively, the Fund could change its investment objective by, for example, seeking to track an alternative index that does not include A shares as its component securities or decide to liquidate the Fund. Special Risk Considerations of Investing in China. Investing in securities of Chinese issuers involves certain risks and considerations not typically associated with investing in securities of U.S. issuers, including, among others, (i) the small size of the market for Chinese securities and the low volume of trading, resulting in lack of liquidity and in price volatility, (ii) currency devaluations and other currency exchange rate fluctuations or blockage, (iii) the nature and extent of intervention by the Chinese government in the Chinese securities markets, whether such intervention will continue and the impact of such intervention or its discontinuation, (iv) the risk of nationalization or expropriation of assets, (v) the risk that the Chinese government may decide not to continue to support economic reform programs, (vi) limitations on the use of brokers, (vii) higher rates of inflation, (viii) greater political, economic and social uncertainty, (ix) market volatility caused by any potential regional territorial conflicts or natural disasters, (x) the risk of increased trade tariffs, embargoes and other trade limitations, and (xi) custody risks associated with investing through a RQFII. A Shares Tax Risk. Uncertainties in the Chinese tax rules governing taxation of income and gains from investments in A shares could result in unexpected tax liabilities for the Fund. China generally imposes withholding tax at a rate of 10% on dividends and interest derived by QFIIs from issuers resident in China. China also imposes withholding tax at a rate of 10% on capital gains derived by nonresident enterprises from investments in an issuer resident in China. There is at present, however, no direct authority on the application of these taxes to an RQFII. In the case of the capital gains tax, moreover, the methodology for calculating and collecting the tax is as yet undetermined, and the Chinese tax authorities are not currently enforcing the collection of the tax. The withholding taxes on dividends, interest and capital gains may in principle be subject to a reduced rate under an applicable tax treaty, but the application of such treaties in the case of an RQFII acting for a foreign investor such as the Fund is also uncertain. Finally, it is also unclear how China’s business tax may apply to activities of an RQFII and how such application may be affected by tax treaty provisions. The Fund will be liable to the Sub-Adviser for any Chinese tax that is imposed on the Sub-Adviser with respect to the Fund’s investments. The PRC rules for taxation of RQFIIs (and QFIIs) are evolving and the tax regulations to be issued by the PRC State Administration of Taxation and/or PRC Ministry of Finance to clarify the subject matter may apply retrospectively, even if such rules are adverse to the Fund and its investors. As described below under “Taxes —Taxes on Distributions,” the Fund may elect, for U.S. federal income tax purposes, to treat Chinese taxes (including withholding taxes) paid by the Fund as paid by its shareholders. Even if the Fund is qualified to make that election and does so, however, your ability to claim a credit for certain Chinese taxes may be limited under general U.S. tax principles. Notwithstanding the uncertainty concerning the Chinese taxation of income derived from the Fund’s investments in A shares, the Fund presently does not intend to establish a reserve, accrual or other provision for Chinese taxes. The imposition of such taxes, particularly on a retrospective basis, could have a material adverse effect on the Fund’s returns. In addition, to the extent the Fund invests in swaps and other derivative instruments, such investments may be less tax-efficient from a U.S. tax perspective than direct investment in A shares and may be subject to special U.S. federal income tax rules that could adversely affect the Fund. Also the Fund may be required to periodically adjust its positions in those instruments to comply with certain regulatory requirements which may further cause these investments to be less efficient than a direct investment in A shares. Should the Chinese government impose restrictions on the Fund’s ability to repatriate funds associated with direct investment in A shares, the Fund may be unable to satisfy distribution requirements applicable to regulated investment companies (“RICs”) under the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), and the Fund may therefore be subject to Fund-level U.S. federal taxes. Derivatives Risk. The Fund’s investments in derivatives and swap contracts, in particular, may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, lack of availability and counterparty risk. To the extent the Fund invests in derivatives to seek to hedge risk or limit leveraged exposure created by other investments, there is no guarantee that such hedging strategies will be effective at managing risk or limiting exposure to leveraged investments. The Fund could lose more than the principal amount invested. Currency and Repatriation Risk. The Underlying Index is calculated in RMB (CNY) whereas the Fund’s reference currency is the U.S. dollar. As a result, the Fund’s return may be adversely affected by currency exchange rates. In addition, the Chinese government heavily regulates the domestic exchange of foreign currencies within China. Chinese law requires that all domestic transactions must be settled in RMB, places significant restrictions on the remittance of foreign currency, and strictly regulates currency exchange from RMB. There is no assurance that there will always be sufficient amounts of RMB for the Fund to remain fully invested. Repatriations by RQFIIs are currently permitted daily and are not subject to repatriation restrictions or prior regulatory approval. However, there is no assurance that Chinese rules and regulations will not change or that repatriation restrictions will not be imposed in the future. Further, such changes to the Chinese rules and regulations may be applied retroactively. Any restrictions on repatriation of the Fund’s portfolio investments may have an adverse effect on the Fund’s ability to meet redemption requests. Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers involve risks beyond those associated with investments in U.S. securities. These additional risks include greater market volatility, the availability of less reliable financial information, higher transactional and custody costs, taxation by foreign governments, decreased market liquidity and political instability. Emerging Market Issuers Risk. Investments in securities of emerging market issuers are exposed to a number of risks that may make these investments volatile in price or difficult to trade. Political risks may include unstable governments, nationalization, restrictions on foreign ownership, laws that prevent investors from getting their money out of a country and legal systems that do not protect property rights as well as the laws of the U.S. Market risks may include economies that concentrate in only a few industries, securities issues that are held by only a few investors, limited trading capacity in local exchanges and the possibility that markets or issues may be manipulated by foreign nationals who have inside information. Equity Securities Risk. An investment in the Fund involves risks similar to those of investing in any fund of equity securities, such as market fluctuations, changes in interest rates and perceived trends in stock prices. Equity securities are subject to volatile changes in value and their values may be more volatile than other asset classes. Financial Services Sector Risk. The Fund invests a significant portion of its assets in securities of issuers in the financial services sector. The financial services industries are subject to extensive government regulation, can be subject to relatively rapid change due to increasingly blurred distinctions between service segments, and can be significantly affected by availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, and price competition. In addition, the deterioration of the credit markets since late 2007 generally has caused an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. The Chinese government encourages banks and certain non-banking financial institutions to conduct strategic transformation and financial innovations in various areas, and continue to facilitate greater access to China’s financial industries. Such changes may have an adverse effect on the value of the Fund’s financial institution holdings. The Fund also may be subject to ownership restrictions with respect to its investments in banks and certain other financial institutions in China. Industrials Sector Risk. The Fund invests a significant portion of its assets in securities issued by companies in the industrials sector. Companies in the industrials sector may be adversely affected by changes in government regulation, world events and economic conditions. In addition, these companies are at risk for environmental damage claims. Companies in this sector could be adversely affected by commodity price volatility, changes in exchange rates, imposition of import controls, increased competition, depletion of resources, technological developments and labor relations. Basic Materials Sector Risk. The Fund invests a significant portion of its assets in securities issued by companies in the basic materials sector, which include companies that manufacture chemicals, construction materials, glass and paper products, as well as metals, minerals and mining companies. Companies engaged in the production and distribution of basic materials may be adversely affected by changes in world events, political and economic conditions, energy conservation, environmental policies, commodity price volatility, changes in exchange rates, imposition of import controls, increased competition, depletion of resources and labor relations. Market Risk. The prices of the securities in the Fund are subject to the risks associated with investing in equity securities, including general economic conditions and sudden and unpredictable drops in value. The Fund’s NAV and market price, like security prices generally, will fluctuate within a wide range in response to these and other factors. Passive Investment Risk. The Fund is managed with a passive investment strategy, attempting to track the performance of an unmanaged index of securities. This differs from an actively managed fund, which typically seeks to outperform a benchmark index. As a result, the Fund may hold constituent securities of the Underlying Index regardless of the current or projected performance of a specific security or a particular industry or market sector. 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. Tracking Error Risk. The performance of the Fund may diverge from that of its Underlying Index due to operating expenses, transaction costs, cash flows and operational inefficiencies. In addition, the Fund may not be able to invest in certain securities included in the Underlying Index or invest in them in the exact proportions they represent of the Underlying Index due to legal restrictions or limitations imposed by the Chinese Government or a lack of liquidity on stock exchanges in which such securities trade. To the extent the Fund calculates its net asset value (“NAV”) based on fair value prices and the value of the Underlying Index is based on securities’ closing prices on local foreign markets (i.e., the value of the Underlying Index is not based on fair value prices), the Fund’s ability to track the Underlying Index may be adversely affected. If the Fund uses a representative sampling approach, it may cause the Fund to not be as well correlated with the return of the Underlying Index as would be the case if the Fund purchased all of the securities in the Underlying Index in the proportions represented in the Underlying Index. Because the Fund bears the costs and risks associated with buying and selling securities while such costs and risks are not factored into the return of the Underlying Index, the Fund’s return may deviate significantly from the return of the Underlying Index. Cash Transactions Risk. Unlike most other ETFs, the Fund expects to effect all of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio investments to obtain the cash needed to distribute redemption proceeds at an inopportune time. This may cause the Fund to recognize gains or losses that it might not have incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in kind. As a practical matter, only institutions and large investors, such as market makers or other large broker-dealers, purchase or redeem Creation Units. Most investors will buy and sell shares of the Fund on the Exchange. Valuation Risk. 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. Non-Diversification Risk. The Fund is non-diversified and may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance. Concentration Risk. To the extent that the Fund’s investments are concentrated in a particular industry, the Fund will be susceptible to loss due to adverse occurrences affecting that industry. Based on the current composition of the Index, it is expected that the Fund’s assets will be concentrated in the financial services sector and that the Fund will be subject to the risk that economic, political or other conditions that have a negative effect on that sector may adversely affect the Fund to a greater extent than if the Fund’s assets were invested in a wider variety of sectors or industries. Shares May Trade at Prices Different Than NAV. Shares may trade below their net asset value (“NAV”). The NAV of shares will fluctuate with changes in the market value of the Fund’s holdings. In addition, although the Fund’s shares are currently listed on the Exchange, there can be no assurance that an active trading market for shares will develop or be maintained. Capitalization Securities Risk. The Fund’s investments may be composed primarily of, or have significant exposure to, securities in a particular capitalization range, e.g., large, mid or small-cap securities. As a result, the Fund may be subject to the risk that the predominate capitalization range represented in the Underlying Index and, thus, the Fund’s portfolio may underperform other segments of the Chinese equity market or the equity market as a whole.
Risk Lose Money [Text]	rr_RiskLoseMoney	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.
Risk Nondiversified Status [Text]	rr_RiskNondiversifiedStatus	Non-Diversification Risk. The Fund is non-diversified and may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance.

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 fund operating expenses or in the example, affect the Fund’s performance.

Principal Investment Strategies

The Underlying Index is designed to reflect the price fluctuation and performance of the China A share market and is composed of the 300 largest and most liquid stocks in the China A share market. The Underlying Index includes small-cap, mid-cap, and large-cap stocks. The Fund, using a “passive” or indexing investment approach, attempts to approximate the investment performance of 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 be 95% or better. A figure of 100% would indicate perfect correlation.

A shares are equity securities issued by companies incorporated in mainland China and are denominated and traded in renminbi (“RMB”) on the Shenzhen and Shanghai Stock Exchanges. Subject to minor exceptions, under current regulations in the People’s Republic of China (“China” or the “PRC”), foreign investors can invest in the domestic PRC securities market only through certain foreign institutional investors that have obtained status as a Qualified Foreign Institutional Investor (“QFII”) or a Renminbi Qualified Foreign Institutional Investor (“RQFII”) from the China Securities Regulatory Commission (“CSRC”) and have been granted a specific aggregate dollar amount investment quota by the China’s State Administration of Foreign Exchange (“SAFE”) to invest foreign freely convertible currencies (in the case of a QFII) and RMB (in the case of a RQFII) in the PRC for the purpose of investing in the PRC’s domestic securities markets.

The Sub-Adviser expects to obtain a RQFII license and to be granted, on behalf of the Fund, an estimated initial RQFII quota of $700 million. The Sub-Adviser, on behalf of the Fund, may invest in A shares and other permitted China securities listed on the Shanghai and Shenzhen Stock Exchanges up to the specified quota amount. The Sub-Adviser may apply for an increase of the initial RQFII quota if it uses the initial quota in its entirety.

The Sub-Adviser expects to use a full replication indexing strategy to seek to track the Underlying Index. As such, the Sub-Adviser expects to invest directly in the component securities (or a substantial number of the component securities) of the Underlying Index in substantially the same weightings in which they are represented in the Underlying Index. If it is not possible for the Sub-Adviser to acquire component securities due to limited availability or regulatory restrictions, the Sub-Adviser may use a representative sampling indexing strategy to seek to track the Underlying Index instead of a full replication indexing strategy. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index when the Sub-Adviser is using a representative sampling indexing strategy.

The Fund will normally invest at least 80% of its total assets in securities of issuers that comprise the Underlying Index. While the Fund intends to invest primarily and directly in A shares, the Fund also may invest in securities of issuers not included in the Underlying Index, swap contracts and other types of derivative instruments, and other pooled investment vehicles that the Adviser and/or Sub-Adviser believes will help the Fund to achieve its investment objective. The remainder of the Fund’s assets will be invested primarily in money market instruments and cash equivalents. Under normal circumstances, the Fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in Chinese securities.

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to the extent that its Underlying Index is concentrated. As of December 31, 2012, the Underlying Index is concentrated in the financial services sector. The Fund will also have significant exposure to the Basic Materials and Industrials sectors.

Summary of Principal Risks

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. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective, as well as numerous other risks that are described in greater detail in the section of the Prospectus entitled “Further Discussion of Principal Risks” and in the Statement of Additional Information (“SAI”).

Special Risk Considerations Relating to the RQFII Regime and Investments in A Shares. The Adviser’s ability to achieve its investment objective by investing in the component securities of the Underlying Index is dependent on the continuous availability of A shares and the Sub-Adviser’s ability to obtain additional RQFII quota on behalf of the Fund. If the Sub-Adviser’s RQFII quota is or becomes inadequate to meet the investment needs of the Fund or if the Sub-Adviser is unable to maintain its RQFII status, the Adviser and/or Sub-Adviser may seek to gain exposure to the A shares market by investing in securities not included in the Underlying Index, swaps and other derivative instruments, and other pooled investment vehicles that provide exposure to the A shares market until additional RQFII quota can be obtained. A reduction in or elimination of the RQFII quota may not only adversely affect the ability of the Fund to invest directly in A shares, but also the willingness of swap counterparties to engage in swaps and the performance of pooled investment vehicles linked to the performance of A shares. Therefore, any such reduction or elimination may have a material adverse effect on the ability of the Fund to achieve its investment objective. These risks are compounded by the fact that at present there are only a limited number of firms and counterparties that have QFII or RQFII status or are otherwise able to obtain A shares quota. In addition, the RQFII quota may be reduced or revoked by the Chinese regulators if, among other things, the Sub-Adviser fails to observe SAFE and other applicable Chinese regulations, which could also lead to other adverse consequences, including the requirement that the Fund dispose of its A shares holdings.

If the Fund is unable to obtain sufficient exposure to the performance of the Underlying Index due to the limited availability of RQFII quota or other investments that provide exposure to the performance of A shares, the Fund could, among other actions, suspend creations until the Sub-Adviser determines that the requisite exposure to the Underlying Index is obtainable. During the period that creations are suspended, the Fund could trade at a significant premium or discount to the NAV and could experience substantial redemptions. Alternatively, the Fund could change its investment objective by, for example, seeking to track an alternative index that does not include A shares as its component securities or decide to liquidate the Fund.

Special Risk Considerations of Investing in China. Investing in securities of Chinese issuers involves certain risks and considerations not typically associated with investing in securities of U.S. issuers, including, among others, (i) the small size of the market for Chinese securities and the low volume of trading, resulting in lack of liquidity and in price volatility, (ii) currency devaluations and other currency exchange rate fluctuations or blockage, (iii) the nature and extent of intervention by the Chinese government in the Chinese securities markets, whether such intervention will continue and the impact of such intervention or its discontinuation, (iv) the risk of nationalization or expropriation of assets, (v) the risk that the Chinese government may decide not to continue to support economic reform programs, (vi) limitations on the use of brokers, (vii) higher rates of inflation, (viii) greater political, economic and social uncertainty, (ix) market volatility caused by any potential regional territorial conflicts or natural disasters, (x) the risk of increased trade tariffs, embargoes and other trade limitations, and (xi) custody risks associated with investing through a RQFII.

A Shares Tax Risk. Uncertainties in the Chinese tax rules governing taxation of income and gains from investments in A shares could result in unexpected tax liabilities for the Fund. China generally imposes withholding tax at a rate of 10% on dividends and interest derived by QFIIs from issuers resident in China. China also imposes withholding tax at a rate of 10% on capital gains derived by nonresident enterprises from investments in an issuer resident in China. There is at present, however, no direct authority on the application of these taxes to an RQFII. In the case of the capital gains tax, moreover, the methodology for calculating and collecting the tax is as yet undetermined, and the Chinese tax authorities are not currently enforcing the collection of the tax. The withholding taxes on dividends, interest and capital gains may in principle be subject to a reduced rate under an applicable tax treaty, but the application of such treaties in the case of an RQFII acting for a foreign investor such as the Fund is also uncertain. Finally, it is also unclear how China’s business tax may apply to activities of an RQFII and how such application may be affected by tax treaty provisions. The Fund will be liable to the Sub-Adviser for any Chinese tax that is imposed on the Sub-Adviser with respect to the Fund’s investments.

The PRC rules for taxation of RQFIIs (and QFIIs) are evolving and the tax regulations to be issued by the PRC State Administration of Taxation and/or PRC Ministry of Finance to clarify the subject matter may apply retrospectively, even if such rules are adverse to the Fund and its investors.

As described below under “Taxes —Taxes on Distributions,” the Fund may elect, for U.S. federal income tax purposes, to treat Chinese taxes (including withholding taxes) paid by the Fund as paid by its shareholders. Even if the Fund is qualified to make that election and does so, however, your ability to claim a credit for certain Chinese taxes may be limited under general U.S. tax principles.

Notwithstanding the uncertainty concerning the Chinese taxation of income derived from the Fund’s investments in A shares, the Fund presently does not intend to establish a reserve, accrual or other provision for Chinese taxes. The imposition of such taxes, particularly on a retrospective basis, could have a material adverse effect on the Fund’s returns.

In addition, to the extent the Fund invests in swaps and other derivative instruments, such investments may be less tax-efficient from a U.S. tax perspective than direct investment in A shares and may be subject to special U.S. federal income tax rules that could adversely affect the Fund. Also the Fund may be required to periodically adjust its positions in those instruments to comply with certain regulatory requirements which may further cause these investments to be less efficient than a direct investment in A shares.

Should the Chinese government impose restrictions on the Fund’s ability to repatriate funds associated with direct investment in A shares, the Fund may be unable to satisfy distribution requirements applicable to regulated investment companies (“RICs”) under the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), and the Fund may therefore be subject to Fund-level U.S. federal taxes.

Derivatives Risk. The Fund’s investments in derivatives and swap contracts, in particular, may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, lack of availability and counterparty risk. To the extent the Fund invests in derivatives to seek to hedge risk or limit leveraged exposure created by other investments, there is no guarantee that such hedging strategies will be effective at managing risk or limiting exposure to leveraged investments. The Fund could lose more than the principal amount invested.

Currency and Repatriation Risk. The Underlying Index is calculated in RMB (CNY) whereas the Fund’s reference currency is the U.S. dollar. As a result, the Fund’s return may be adversely affected by currency exchange rates. In addition, the Chinese government heavily regulates the domestic exchange of foreign currencies within China. Chinese law requires that all domestic transactions must be settled in RMB, places significant restrictions on the remittance of foreign currency, and strictly regulates currency exchange from RMB. There is no assurance that there will always be sufficient amounts of RMB for the Fund to remain fully invested. Repatriations by RQFIIs are currently permitted daily and are not subject to repatriation restrictions or prior regulatory approval. However, there is no assurance that Chinese rules and regulations will not change or that repatriation restrictions will not be imposed in the future. Further, such changes to the Chinese rules and regulations may be applied retroactively. Any restrictions on repatriation of the Fund’s portfolio investments may have an adverse effect on the Fund’s ability to meet redemption requests.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers involve risks beyond those associated with investments in U.S. securities. These additional risks include greater market volatility, the availability of less reliable financial information, higher transactional and custody costs, taxation by foreign governments, decreased market liquidity and political instability.

Emerging Market Issuers Risk. Investments in securities of emerging market issuers are exposed to a number of risks that may make these investments volatile in price or difficult to trade. Political risks may include unstable governments, nationalization, restrictions on foreign ownership, laws that prevent investors from getting their money out of a country and legal systems that do not protect property rights as well as the laws of the U.S. Market risks may include economies that concentrate in only a few industries, securities issues that are held by only a few investors, limited trading capacity in local exchanges and the possibility that markets or issues may be manipulated by foreign nationals who have inside information.

Equity Securities Risk. An investment in the Fund involves risks similar to those of investing in any fund of equity securities, such as market fluctuations, changes in interest rates and perceived trends in stock prices. Equity securities are subject to volatile changes in value and their values may be more volatile than other asset classes.

Financial Services Sector Risk. The Fund invests a significant portion of its assets in securities of issuers in the financial services sector. The financial services industries are subject to extensive government regulation, can be subject to relatively rapid change due to increasingly blurred distinctions between service segments, and can be significantly affected by availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, and price competition. In addition, the deterioration of the credit markets since late 2007 generally has caused an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. The Chinese government encourages banks and certain non-banking financial institutions to conduct strategic transformation and financial innovations in various areas, and continue to facilitate greater access to China’s financial industries. Such changes may have an adverse effect on the value of the Fund’s financial institution holdings. The Fund also may be subject to ownership restrictions with respect to its investments in banks and certain other financial institutions in China.

Industrials Sector Risk. The Fund invests a significant portion of its assets in securities issued by companies in the industrials sector. Companies in the industrials sector may be adversely affected by changes in government regulation, world events and economic conditions. In addition, these companies are at risk for environmental damage claims. Companies in this sector could be adversely affected by commodity price volatility, changes in exchange rates, imposition of import controls, increased competition, depletion of resources, technological developments and labor relations.

Basic Materials Sector Risk. The Fund invests a significant portion of its assets in securities issued by companies in the basic materials sector, which include companies that manufacture chemicals, construction materials, glass and paper products, as well as metals, minerals and mining companies. Companies engaged in the production and distribution of basic materials may be adversely affected by changes in world events, political and economic conditions, energy conservation, environmental policies, commodity price volatility, changes in exchange rates, imposition of import controls, increased competition, depletion of resources and labor relations.

Market Risk. The prices of the securities in the Fund are subject to the risks associated with investing in equity securities, including general economic conditions and sudden and unpredictable drops in value. The Fund’s NAV and market price, like security prices generally, will fluctuate within a wide range in response to these and other factors.

Passive Investment Risk. The Fund is managed with a passive investment strategy, attempting to track the performance of an unmanaged index of securities. This differs from an actively managed fund, which typically seeks to outperform a benchmark index. As a result, the Fund may hold constituent securities of the Underlying Index regardless of the current or projected performance of a specific security or a particular industry or market sector. 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.

Tracking Error Risk. The performance of the Fund may diverge from that of its Underlying Index due to operating expenses, transaction costs, cash flows and operational inefficiencies. In addition, the Fund may not be able to invest in certain securities included in the Underlying Index or invest in them in the exact proportions they represent of the Underlying Index due to legal restrictions or limitations imposed by the Chinese Government or a lack of liquidity on stock exchanges in which such securities trade. To the extent the Fund calculates its net asset value (“NAV”) based on fair value prices and the value of the Underlying Index is based on securities’ closing prices on local foreign markets (i.e., the value of the Underlying Index is not based on fair value prices), the Fund’s ability to track the Underlying Index may be adversely affected. If the Fund uses a representative sampling approach, it may cause the Fund to not be as well correlated with the return of the Underlying Index as would be the case if the Fund purchased all of the securities in the Underlying Index in the proportions represented in the Underlying Index. Because the Fund bears the costs and risks associated with buying and selling securities while such costs and risks are not factored into the return of the Underlying Index, the Fund’s return may deviate significantly from the return of the Underlying Index.

Cash Transactions Risk. Unlike most other ETFs, the Fund expects to effect all of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio investments to obtain the cash needed to distribute redemption proceeds at an inopportune time. This may cause the Fund to recognize gains or losses that it might not have incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in kind. As a practical matter, only institutions and large investors, such as market makers or other large broker-dealers, purchase or redeem Creation Units. Most investors will buy and sell shares of the Fund on the Exchange.

Valuation Risk. 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.

Non-Diversification Risk. The Fund is non-diversified and may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance.

Concentration Risk. To the extent that the Fund’s investments are concentrated in a particular industry, the Fund will be susceptible to loss due to adverse occurrences affecting that industry. Based on the current composition of the Index, it is expected that the Fund’s assets will be concentrated in the financial services sector and that the Fund will be subject to the risk that economic, political or other conditions that have a negative effect on that sector may adversely affect the Fund to a greater extent than if the Fund’s assets were invested in a wider variety of sectors or industries.

Shares May Trade at Prices Different Than NAV. Shares may trade below their net asset value (“NAV”). The NAV of shares will fluctuate with changes in the market value of the Fund’s holdings. In addition, although the Fund’s shares are currently listed on the Exchange, there can be no assurance that an active trading market for shares will develop or be maintained.

Capitalization Securities Risk. The Fund’s investments may be composed primarily of, or have significant exposure to, securities in a particular capitalization range, e.g., large, mid or small-cap securities. As a result, the Fund may be subject to the risk that the predominate capitalization range represented in the Underlying Index and, thus, the Fund’s portfolio may underperform other segments of the Chinese equity market or the equity market as a whole.

Performance Information

As of the date of the Prospectus, the Fund has been in operation for less than one full calendar year and therefore does not report its performance information. Once available, the Fund’s performance information will be accessible on the Fund’s website at www.dbxetf.com and will provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance and by showing how the Fund’s returns compare with those of a broad measure of market performance.

[1] Because the Fund is new, “Other Expenses” are based on estimated amounts for the current fiscal year.

[2] Effective as of the date of this Prospectus, DBX Advisors LLC (the “Adviser”) has contractually agreed through September 30, 2015 to waive fees and/or reimburse the Fund’s expenses in order to limit the Fund’s net annual operating expenses to 0.90% of the Fund’s average daily net assets, except for interest expense (and any other expenses related to borrowing), taxes, brokerage expenses, distribution fees or expenses, litigation expenses and other extraordinary expenses (the “Expense Cap”). The Expense Cap will remain in effect until at least September 30, 2015 and may only be terminated with the consent of the Trust’s Board of Trustees (the “Board”) (and may not be terminated by the Adviser) prior to that time.
