Portfolio Turnover

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities or other instruments. 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. During the most recent fiscal year, the Fund’s portfolio turnover rate was 39% of the average value of its portfolio.

The following example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of the Shares at the end of those periods. This example assumes that the Fund provides a return of 5% a year and that operating expenses remain the same. This example does not include the brokerage commission that you may pay to buy and sell exchange-traded Shares of the Fund. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Strategy [Heading]

rr_StrategyHeading

Principal Investment Strategies

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is an exchange-traded fund (“ETF”). The Fund seeks to achieve its investment objective by attempting to replicate the portfolio of the Composite Underlying Index through investments in equity securities, including common shares traded on local exchanges, American Depositary Receipts (“ADRs”) and Global Depositary Receipts (“GDRs”). ADRs and GDRs represent ownership interests in shares of foreign companies that are held in financial institution custodial accounts, and are traded on exchanges in the United States and around the world.

Under normal circumstances, the Fund will invest at least 80% of its net assets in companies included in the Fund’s Composite Underlying Index and generally expects to be substantially invested at such times, with at least 95% of its net assets invested in these securities. The Fund will provide shareholders with at least 60 days’ notice prior to any changes in this policy. The Fund does not seek temporary defensive positions when equity markets decline or appear to be overvalued.

The Fund’s intention is to replicate the constituent securities of the Composite Underlying Index as closely as possible using ADRs, GDRs or ordinary local shares (including through its Mauritius Subsidiary (as defined below)). In certain circumstances, when it may not be possible or practicable to fully implement a replication strategy, the Fund may utilize a “representative sampling” strategy whereby the Fund would hold a significant number of the component securities of the Composite Underlying Index, but may not track the index with the same degree of accuracy as would an investment vehicle replicating the entire index. Active market trading of Fund Shares may cause more frequent creation or redemption activities and to the extent such creation and redemption activities are not conducted in-kind could increase the rate of portfolio turnover.

The Fund will concentrate its investments (i.e., hold 25% or more of its net assets) in a particular industry or group of industries to approximately the same extent that the Composite Underlying Index is concentrated. The Composite Underlying Index is comprised of a representative sample of 100 Emerging Markets companies deemed to be the 10 leading companies in each of the 10 “Industries” as defined by the Industry Classification Benchmark (“ICB”) system. As of June 30, 2011, the float-adjusted market capitalization of companies included in the Composite Underlying Index ranged from US$1.3 billion to US$87.8 billion, with an average of US$15.0 billion. Many of these companies would be considered medium capitalization or “mid-cap” companies.

The Fund may invest its assets in a wholly owned subsidiary in Mauritius (the “Mauritius Subsidiary”), which in turn invests virtually all of its assets in Indian securities, based on the number of Indian securities that are included in the Composite Underlying Index. Through such investment structure, the Fund obtains benefits under the tax treaty between Mauritius and India.

Risk [Heading]

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Like all investments, investing in the Fund entails risks, including the risk that you may lose part or all of the money you invest.

Equity Securities The price of one or more of the equity securities in the Fund’s portfolio may fall. Many factors can adversely affect an equity security’s performance, including both general financial market conditions and factors related to a specific company, industry or geographic region.

Market Price Variance As an ETF, the Fund’s Shares generally trade in the secondary market on the NYSE Arca, Inc. (the “Exchange”) at market prices that change throughout the day. Although it is expected that the market price of Fund Shares will approximate the Fund’s net asset value per Share (“NAV”), there may be times when the market price and the NAV vary significantly. You may pay more than NAV when you buy Shares of the Fund on the Exchange, and you may receive less than NAV when you sell those Shares on the Exchange.

Non-Correlation The Fund’s return may not match the return of the Composite Underlying Index. The Fund incurs a number of operating expenses that are not reflected in the Composite Underlying Index, including the cost of buying and selling securities. If the Fund is not fully invested, holding cash balances may prevent it from tracking the Composite Underlying Index.

Market Liquidity for Fund Shares As an ETF, Fund Shares are not individually redeemable securities. There is no assurance that an active trading market for Fund Shares will develop or be maintained.

Non-Diversification The Fund is non-diversified and, as a result, may have greater volatility than diversified funds. Because the Fund may invest a larger percentage of its assets in securities of a single company than a diversified fund, the performance of that company can have a substantial impact on the Fund’s Share price.

Concentration The Fund will concentrate in industries to the same extent as the Composite Underlying Index. The Fund may be adversely affected by increased price volatility of securities in those industries, and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting those industries.

Foreign Investment Foreign investments may be more volatile because of economic or political developments, public health and safety issues, demographic changes, market inefficiencies, lack of regulatory oversight, or a higher risk that essential investment information may be incomplete, unavailable or inaccurate. Restrictions on currency trading may be imposed by foreign countries, which may adversely affect the value of the Fund’s portfolio securities.

Emerging Markets Investments in emerging market securities are subject to even greater risks than for foreign investments generally, including increased risks of: illiquidity of securities; price volatility; inflation or deflation; restrictions on foreign investment; nationalization; higher taxation; economic and political instability; pervasive corruption and crime; less governmental regulation; and less developed legal systems.

Foreign Currency The value of an investment denominated in a foreign currency could change significantly as foreign currencies strengthen or weaken relative to the U.S. dollar. Risks related to foreign currencies also include those related to economic or political developments, market inefficiencies or a higher risk that essential investment information may be incomplete, unavailable or inaccurate.

Mid-Cap Companies Medium capitalization companies may have greater volatility in price than the stocks of large capitalization companies due to limited product lines or resources or a dependency upon a particular market niche.

Liquidity In certain circumstances, the Fund might not be able to dispose of certain holdings quickly or at prices that represent true market value in the judgment of Emerging Global Advisors, LLC (“EGA”), sub-adviser to the Fund, preventing the Fund from tracking the Composite Underlying Index.

Depositary Receipts Changes in foreign currency exchange rates will affect the value of ADRs or GDRs and, therefore, may affect the value of the Fund’s portfolio.

Risk Nondiversified Status [Text]

rr_RiskNondiversifiedStatus

The Fund is non-diversified and, as a result, may have greater volatility than diversified funds. Because the Fund may invest a larger percentage of its assets in securities of a single company than a diversified fund, the performance of that company can have a substantial impact on the Fund’s Share price.

If the Fund is not fully invested, holding cash balances may prevent it from tracking the Consumer Services Underlying Index.

Consumer Services Concentration Because the Consumer Services Underlying Index is concentrated in the consumer services industry, the Fund may be adversely affected by increased price volatility of securities in that industry, and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that industry. The success of consumer services suppliers and retailers is tied closely to the performance of the domestic and international economy, interest rates, currency exchange rates, competition, preferences, and consumer confidence.

Depositary Receipts Changes in foreign currency exchange rates will affect the value of ADRs or GDRs and, therefore, may affect the value of the Fund’s portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is an exchange-traded fund (“ETF”). The Fund seeks to achieve its investment objective by attempting to replicate the portfolio of the Energy Underlying Index through investments in equity securities, including common shares traded on local exchanges, American Depositary Receipts (“ADRs”) and Global Depositary Receipts (“GDRs”). ADRs and GDRs represent ownership interests in shares of foreign companies that are held in financial institution custodial accounts, and are traded on exchanges in the United States and around the world. The Energy Underlying Index includes companies whose businesses generally involve: oil and gas production; oil equipment, services and distribution; and alternative energy.

Under normal circumstances, the Fund will invest at least 80% of its net assets in securities of Emerging Markets Energy companies that are included in the Fund’s Energy Underlying Index and generally expects to be substantially invested at such times, with at least 95% of its net assets invested in those securities. The Fund will provide shareholders with at least 60 days’ notice prior to any changes in this policy. The Fund does not seek temporary defensive positions when equity markets decline or appear to be overvalued.

The Fund’s intention is to replicate the constituent securities of the Energy Underlying Index as closely as possible using ADRs, GDRs or ordinary local shares (including through its Mauritius Subsidiary (as defined below)). In certain circumstances, when it may not be possible or practicable to fully implement a replication strategy, the Fund may utilize a “representative sampling” strategy whereby the Fund would hold a significant number of the component securities of the Energy Underlying Index, but may not track the index with the same degree of accuracy as would an investment vehicle replicating the entire index. Active market trading of Fund Shares may cause more frequent creation or redemption activities and to the extent such creation and redemption activities are not conducted in-kind could increase the rate of portfolio turnover.

The Fund will concentrate its investments (i.e., hold 25% or more of its net assets) in a particular industry or group of industries to approximately the same extent that the Energy Underlying Index is concentrated. The Energy Underlying Index is comprised of publicly traded firms in the “Oil and Gas Industry” as defined by the Industry Classification Benchmark (“ICB”) system. As of June 30, 2011, the float-adjusted market capitalization of companies included in the Energy Underlying Index ranged from US$1.0 billion to US$11.3 billion, with an average of US$3.9 billion. Many of these companies would be considered medium capitalization or “mid-cap” companies.

The Fund may invest its assets in a wholly owned subsidiary in Mauritius (the “Mauritius Subsidiary”), which in turn invests virtually all of its assets in Indian securities, based on the number of Indian securities that are included in the Energy Underlying Index. Through such investment structure, the Fund obtains benefits under the tax treaty between Mauritius and India.

The Industrials Underlying Index includes companies whose businesses generally involve: construction and materials; aerospace and defense; general industrials; electronic and electrical equipment; industrial engineering; industrial transportation; and support services.

Under normal circumstances, the Fund will invest at least 80% of its net assets in securities of Emerging Markets Industrials companies that are included in the Fund’s Industrials Underlying Index and generally expects to be substantially invested at such times, with at least 95% of its net assets invested in those securities. The Fund will provide shareholders with at least 60 days’ notice prior to any changes in this policy. The Fund does not seek temporary defensive positions when equity markets decline or appear to be overvalued.

The Fund’s intention is to replicate the constituent securities of the Industrials Underlying Index as closely as possible using ADRs, GDRs or ordinary local shares (including through its Mauritius Subsidiary (as defined below)). In certain circumstances, when it may not be possible or practicable to fully implement a replication strategy, the Fund may utilize a “representative sampling” strategy whereby the Fund would hold a significant number of the component securities of the Industrials Underlying Index, but may not track the index with the same degree of accuracy as would an investment vehicle replicating the entire index. Active market trading of Fund Shares may cause more frequent creation or redemption activities and to the extent such creation and redemption activities are not conducted in-kind could increase the rate of portfolio turnover.

The Fund will concentrate its investments (i.e., hold 25% or more of its net assets) in a particular industry or group of industries to approximately the same extent that the Industrials Underlying Index is concentrated. The Industrials Underlying Index is comprised of publicly traded firms in the “Industrials Industry” as defined by the Industry Classification Benchmark (“ICB”) system. As of June 30, 2011, the float-adjusted market capitalization of companies included in the Industrials Underlying Index ranged from US$1.6 billion to US$12.7 billion, with an average of US$3.5 billion. Many of these companies would be considered medium capitalization or “mid-cap” companies.

The Fund may invest its assets in a wholly owned subsidiary in Mauritius (the “Mauritius Subsidiary”), which in turn invests virtually all of its assets in Indian securities, based on the number of Indian securities that are included in the Industrials Underlying Index. Through such investment structure, the Fund obtains benefits under the tax treaty between Mauritius and India.

Like all investments, investing in the Fund entails risks, including the risk that you may lose part or all of the money you invest.

Non-Correlation The Fund’s return may not match the return of the Industrials Underlying Index. The Fund incurs a number of operating expenses that are not reflected in the Industrials Underlying Index, including the cost of buying and selling securities. If the Fund is not fully invested, holding cash balances may prevent it from tracking the Industrials Underlying Index.

Industrials Concentration Because the Industrials Underlying Index is concentrated in the industrials industry, the Fund may be adversely affected by increased price volatility of securities in that industry, and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that industry. Government regulation, world events and economic conditions affect the performance of companies in the industrials industry.

The Fund is an exchange-traded fund (“ETF”). The Fund seeks to achieve its investment objective by attempting to replicate the portfolio of the Technology Underlying Index through investments in equity securities, including common shares traded on local exchanges, American Depositary Receipts (“ADRs”) and Global Depositary Receipts (“GDRs”). ADRs and GDRs represent ownership interests in shares of foreign companies that are held in financial institution custodial accounts, and are traded on exchanges in the United States and around the world. The Technology Underlying Index includes companies whose businesses generally involve: software and computer services; and technology hardware and equipment.

Under normal circumstances, the Fund will invest at least 80% of its net assets in securities of Emerging Markets Technology companies that are included in the Fund’s Technology Underlying Index and generally expects to be substantially invested at such times, with at least 95% of its net assets invested in those securities. The Fund will provide shareholders with at least 60 days’ notice prior to any changes in this policy.

Active market trading of Fund Shares may cause more frequent creation or redemption activities and to the extent such creation and redemption activities are not conducted in-kind could increase the rate of portfolio turnover.

The Fund will concentrate its investments (i.e., hold 25% or more of its net assets) in a particular industry or group of industries to approximately the same extent that the Technology Underlying Index is concentrated.

The Fund pays transaction costs, such as commissions, when it buys and sells securities or other instruments. 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. For the period from September 14, 2010 (commencement of operations) through the most recent fiscal year ended, the Fund’s portfolio turnover rate was 9% of the average value of its portfolio.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund is an exchange-traded fund (“ETF”). The Fund seeks to achieve its investment objective by attempting to replicate the portfolio of the Consumer Titans Underlying Index through investments in equity securities, including common shares traded on local exchanges, American Depositary Receipts (“ADRs”) and Global Depositary Receipts (“GDRs”). ADRs and GDRs represent ownership interests in shares of foreign companies that are held in financial institution custodial accounts, and are traded on exchanges in the United States and around the world. The Consumer Titans Underlying Index includes companies whose businesses generally involve: automobiles and parts; beverages; food production; household goods; leisure goods; personal goods; tobacco; food and drug retail; general retail; media; and travel and leisure.

Under normal circumstances, the Fund will invest at least 80% of its net assets in securities of Emerging Markets Consumer companies that are included in the Fund’s Consumer Titans Underlying Index and generally expects to be substantially invested at such times, with at least 95% of its net assets invested in those securities. The Fund will provide shareholders with at least 60 days’ notice prior to any changes in this policy. The Fund does not seek temporary defensive positions when equity markets decline or appear to be overvalued.

The Fund’s intention is to replicate the constituent securities of the Consumer Titans Underlying Index as closely as possible using ADRs, GDRs or ordinary local shares (including through its Mauritius Subsidiary (as defined below)). In certain circumstances, when it may not be possible or practicable to fully implement a replication strategy, the Fund may utilize a “representative sampling” strategy whereby the Fund would hold a significant number of the component securities of the Consumer Titans Underlying Index, but may not track the index with the same degree of accuracy as would an investment vehicle replicating the entire index. Active market trading of Fund Shares may cause more frequent creation or redemption activities and to the extent such creation and redemption activities are not conducted in-kind could increase the rate of portfolio turnover.

The Fund will concentrate its investments (i.e., hold 25% or more of its net assets) in a particular industry or group of industries to approximately the same extent that the Consumer Titans Underlying Index is concentrated. The Consumer Titans Underlying Index is comprised of publicly traded firms in the “Consumer Goods Industry” and “Consumer Services Industry” as defined by the Industry Classification Benchmark (“ICB”) system. As of June 30, 2011, the float-adjusted market capitalization of companies included in the Consumer Titans Underlying Index ranged from US$2.1 billion to US$22.3 billion, with an average of US$7.3 billion. Many of these companies would be considered medium capitalization or “mid-cap” companies.

The Fund may invest its assets in a wholly owned subsidiary in Mauritius (the “Mauritius Subsidiary”), which in turn invests virtually all of its assets in Indian securities, based on the number of Indian securities that are included in the Consumer Titans Underlying Index. Through such investment structure, the Fund obtains benefits under the tax treaty between Mauritius and India.

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Like all investments, investing in the Fund entails risks, including the risk that you may lose part or all of the money you invest.

Non-Correlation The Fund’s return may not match the return of the Consumer Titans Underlying Index. The Fund incurs a number of operating expenses that are not reflected in the Consumer Titans Underlying Index, including the cost of buying and selling securities. If the Fund is not fully invested, holding cash balances may prevent it from tracking the Consumer Titans Underlying Index.

Consumer Concentration Because the Consumer Titans Underlying Index is concentrated in the consumer goods and services industry, the Fund may be adversely affected by increased price volatility of securities in that industry, and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that industry. The success of consumer goods and services suppliers and retailers is tied closely to the performance of the domestic and international economy, interest rates, currency exchange rates, competition, preferences, and consumer confidence.

Emerging Markets Investments in emerging market securities (including Indian securities) are subject to even greater risks than for foreign investments generally, including increased risks of: illiquidity of securities; price volatility; inflation or deflation; restrictions on foreign investment; nationalization; higher taxation; economic and political instability; pervasive corruption and crime; less governmental regulation; and less developed legal systems.

Depositary Receipts Changes in foreign currency exchange rates will affect the value of ADRs or GDRs and, therefore, may affect the value of the Fund’s portfolio.

The Fund invests substantially all of its assets in a wholly owned subsidiary in Mauritius (the “Mauritius Subsidiary”), which in turn, invests at least 90% of its assets in Indian securities, and the Fund may also invest to some extent in ADRs and GDRs, based on the number of Indian securities that are included in the India Small Cap Underlying Index. Through such investment structure, the Fund obtains benefits under the tax treaty between Mauritius and India.

The Fund’s intention is to replicate the constituent securities of the India Small Cap Underlying Index as closely as possible using ADRs, GDRs or ordinary local shares (including through its Mauritius Subsidiary). In certain circumstances, when it may not be possible or practicable to fully implement a replication strategy, the Fund may utilize a “representative sampling” strategy whereby the Fund would hold a significant number of the component securities of the India Small Cap Underlying Index, but may not track the index with the same degree of accuracy as would an investment vehicle replicating the entire index. Active market trading of Fund Shares may cause more frequent creation or redemption activities and to the extent such creation and redemption activities are not conducted in-kind could increase the rate of portfolio turnover.

The India Small Cap Underlying Index is a free-float market capitalization weighted stock market index comprised of a representative sample of 75 emerging markets companies that INDXX, LLC determines to be representative of small cap companies domiciled in India.

Principal Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Like all investments, investing in the Fund entails risks, including the risk that you may lose part or all of the money you invest.

Non-Correlation The Fund’s return may not match the return of the India Small Cap Underlying Index. The Fund incurs a number of operating expenses that are not reflected in the India Small Cap Underlying Index, including the cost of buying and selling securities and maintaining the Mauritius Subsidiary. If the Fund is not fully invested, holding cash balances may prevent it from tracking the India Small Cap Underlying Index.

Small Cap Companies Small capitalization companies may have greater volatility in price than the stocks of large capitalization companies due to limited product lines or resources or a dependency upon a particular market niche.

Depositary Receipts Changes in foreign currency exchange rates will affect the value of ADRs or GDRs and, therefore, may affect the value of the Fund’s portfolio.

The Fund is an exchange-traded fund (“ETF”). The Fund seeks to achieve its investment objective by attempting to replicate the portfolio of the China Mid Cap Underlying Index through investments in equity securities, including common shares traded on local exchanges, American Depositary Receipts (“ADRs”) and Global Depositary Receipts (“GDRs”). ADRs and GDRs represent ownership interests in shares of foreign companies that are held in financial institution custodial accounts, and are traded on exchanges in the United States and around the world.

Under normal circumstances, the Fund will invest at least 80% of its net assets in securities of Chinese medium market capitalization (“mid cap”) companies included in the China Mid Cap Underlying Index and generally expects to be substantially invested at such times, with at least 95% of its net assets invested in those securities. The Fund invests in Chinese medium capitalization companies, which are generally defined as companies that are domiciled in China that trade on the exchanges of Hong Kong and the U.S. and have a market capitalization that is at least $200 million, but is lower than the 30th highest publicly traded company in China. The Fund does not seek temporary defensive positions when equity markets decline or appear to be overvalued.

The Fund’s intention is to replicate the constituent securities of the China Mid Cap Underlying Index as closely as possible using ADRs, GDRs or ordinary local shares.
