  <rr:StrategyNarrativeTextBlock contextRef="Duration_02Jan2012_01Jan2013S000021351_Member">The Fund is an actively managed exchange traded fund (&amp;#8220;ETF&amp;#8221;) that seeks to achieve its investment objective by investing in short-term securities and instruments designed to provide exposure to Brazilian currency and money market rates. Because the market for money market securities in Brazil generally is less liquid and accessible to foreign investors than corresponding markets in more developed economies, the Fund intends to achieve exposure to Brazilian currency markets by investing primarily in short-term U.S. money market securities and forward currency contracts and swaps. The combination of U.S. money market securities with forward currency contracts and currency swaps is designed to provide exposure equivalent to money market securities denominated in Brazilian real. A forward currency contract is an agreement to buy or sell a specific currency at a future date at a price set at the time of the contract. A currency swap is an agreement between two parties to exchange one currency for another at a future rate. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. A repurchase agreement is a transaction in which the Fund purchases securities or other obligations from a bank or securities dealer and simultaneously commits to resell them to a counterparty at an agreed-upon date or upon demand and at a price reflecting a market rate of interest unrelated to the coupon rate or maturity of the purchased obligations.&lt;br/&gt;&lt;br/&gt;In order to attempt to reduce interest rate risk, the Fund generally will maintain a weighted average portfolio maturity of 90 days or less with respect to the money market securities in its portfolio. The Fund will not purchase any security with a remaining maturity of more than 397 calendar days. All U.S. money market securities acquired by the Fund will be rated in  the upper two short-term ratings by at least two nationally recognized statistical rating organizations (&amp;#8220;NRSROs&amp;#8221;) or, if unrated, deemed to be of equivalent quality. The Fund does not seek to preserve capital in U.S. dollars.&lt;br/&gt;&lt;br/&gt;The decision to secure exposure directly or indirectly will be a function of, among other things, market accessibility, credit exposure, and tax ramifications for foreign investors. If the Fund pursues direct investment, eligible investments include short-term securities issued by the Brazilian government and its agencies or instrumentalities, bank debt obligations and time deposits, bankers&amp;#8217; acceptances, commercial paper, short-term corporate debt obligations, mortgage-backed securities and asset-backed securities.&lt;br/&gt;&lt;br/&gt;The Fund will invest, under normal circumstances, at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in investments whose combined performance is tied economically to Brazil. If, subsequent to an investment, the 80% requirement is no longer met, the Fund&amp;#8217;s future investments will be made in a manner that will bring the Fund into compliance with this policy. The Trust will provide shareholders with sixty (60) days&amp;#8217; prior notice of any change to this policy for the Fund.</rr:StrategyNarrativeTextBlock>
  <rr:RiskNarrativeTextBlock contextRef="Duration_02Jan2012_01Jan2013S000021351_Member">You can lose money on your investment in the Fund. The Fund is subject to the risks described below. Some or all of these risks may adversely affect the Fund&amp;#8217;s net asset value per share (&amp;#8220;NAV&amp;#8221;), trading price, yield, total return and/or ability to meet its objective.&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Investment Risk.&lt;/b&gt; As with all investments, an investment in the Fund is subject to investment risk. Investors in the Fund could lose money, including the possible loss of the entire principal amount of an investment, over short or long periods of time.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Market Risk.&lt;/b&gt; The trading prices of currencies, fixed income securities and other instruments fluctuate in response to a variety of factors. The Fund&amp;#8217;s NAV and market price may fluctuate significantly in response to these factors. As a result, an investor could lose money over short or long periods of time.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Shares of the Fund May Trade at Prices Other Than NAV.&lt;/b&gt; Although it is expected that the market price of the shares of the Fund will approximate the Fund&amp;#8217;s NAV when purchased and sold in the secondary market, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Capital Controls Risk.&lt;/b&gt; Economic conditions, such as volatile currency exchange rates and interest rates, political events and other conditions may, without prior warning, lead to intervention by the government of Brazil and the imposition of &amp;#8220;capital controls.&amp;#8221; Capital controls include the prohibition of, or restrictions on, the ability to transfer currency, securities or other assets. Capital controls may impact the ability of the Fund to buy, sell or otherwise transfer securities or currency, adversely affect the trading market and price for shares of the Fund, and cause the Fund to decline in value.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Cash Redemption Risk.&lt;/b&gt; The Fund&amp;#8217;s investment strategy will require it to effect redemptions, in whole or in part, for cash. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used exclusively.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Counterparty and Issuer Credit Risk.&lt;/b&gt; The financial condition of an issuer of a debt security or other instrument or a counterparty to a derivative or other contract may cause such issuer or counterparty to default, become unable to pay interest or principal due or otherwise fail to honor its obligations. While the Fund attempts to limit credit and counterparty exposure in a manner consistent with its investment objective, the value of an investment in the Fund may change quickly and without warning in response to issuer or counterparty defaults and changes in the credit ratings of the Fund&amp;#8217;s portfolio investments.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Currency Exchange Rate Risk.&lt;/b&gt; The Fund invests a significant portion of its assets in investments denominated in Brazilian real, or in securities that provide exposure to Brazilian real, currency exchange rates or interest rates denominated Brazilian real. Changes in currency exchange rates and the relative value of the Brazilian real will affect the value of the Fund&amp;#8217;s investment and the value of your Fund shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Derivatives Investment Risk.&lt;/b&gt; The Fund will invest in derivatives. Derivatives are subject to a number of risks described elsewhere in this Prospectus, such as interest rate risk, market risk, and credit risk. They also involve the risk that changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, or that the counterparty to a derivative contract might default on its obligations. Derivatives can be volatile and may be less liquid than other securities. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Emerging Markets Risk.&lt;/b&gt; Investments in securities and instruments traded in developing or emerging markets, such as Brazil, or that provide exposure to such securities or markets, can involve additional risks relating to political, economic, or regulatory conditions not associated with investments in U.S. securities and instruments or investments in more developed international markets. Such conditions may impact the ability of the Fund to buy, sell or otherwise transfer securities, adversely affect the trading market and price for Fund shares, and cause the Fund to decline in value. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Foreign Securities Risk.&lt;/b&gt; The Fund invests a significant portion of its assets in non-U.S. securities and instruments, or in securities that provide exposure to such instruments. Investments in non-U.S. securities and instruments involve certain risks that may not be present with investments in U.S. securities, including the risk of loss due to foreign currency fluctuations or to political or economic instability.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Geographic Concentration in Brazil.&lt;/b&gt; Because the Fund concentrates its investments in Brazil, the Fund&amp;#8217;s performance is expected to be closely tied to social, political, and economic conditions within Brazil and to be more volatile than the performance of more geographically diversified funds. The Brazilian economy is sensitive to fluctuations in commodity prices and commodity markets. Additionally, the Brazilian economy generally has experienced and may continue to experience high inflation rates. While the Brazilian economy has experienced growth in recent years, there is no guarantee that this growth will continue. The Brazilian government currently imposes significant taxes on the transfer of currency. These and other factors could have a negative impact on the Fund&amp;#8217;s performance and increase the volatility of an investment in the Fund.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Interest Rate Risk.&lt;/b&gt; Interest rate risk is the risk that fixed income securities will decline in value because of changes in interest rates and other factors, such as perception of an issuer&amp;#8217;s creditworthiness.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Issuer-Specific Risk.&lt;/b&gt; Issuer-specific events, including changes in the financial condition of an issuer, can have a negative impact on the value of the Fund.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Non-Diversification Risk.&lt;/b&gt; The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. To the extent the Fund invests a significant percentage of its assets in a limited number of issuers, the Fund is subject to the risks of investing in those few issuers, and may be more susceptible to a single adverse economic or regulatory occurrence. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Management Risk.&lt;/b&gt; The Fund is actively managed using proprietary investment strategies and processes. There can be no guarantee that these strategies and processes will be successful or that the Fund will achieve its investment objective.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Offshore Investor Risk.&lt;/b&gt; The opportunity for offshore investors, such as the Fund, to access Brazilian markets can be limited due to a variety of factors including currency convertibility issues. These limitations and restrictions may adversely affect the availability, liquidity and pricing of securities in which the Fund seeks to invest. As a result, returns achieved by offshore investors, such as the Fund, could differ from those available to domestic investors in Brazil.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Repurchase Agreement Risk.&lt;/b&gt; The Fund&amp;#8217;s investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Sovereign Debt Risk.&lt;/b&gt; Bonds issued by governments, sometimes referred to as &amp;#8220;sovereign&amp;#8221; debt, present risks not associated with investments in other types of bonds. The government or agency issuing the debt may be unable or unwilling to make interest payments and/or repay the principal owed. In such instance, the Fund may have limited recourse against the issuing government or agency. In the past, governments of emerging market countries have refused to honor their payment obligations on issued bonds.&lt;/li&gt;&lt;/ul&gt;</rr:RiskNarrativeTextBlock>

  <rr:StrategyNarrativeTextBlock contextRef="Duration_02Jan2012_01Jan2013S000021353_Member">The Fund is an actively managed exchange traded fund (&amp;#8220;ETF&amp;#8221;) that seeks to achieve its investment objective by investing in short-term securities and instruments designed to provide exposure to Chinese currency and money market rates. Because the market for money market securities in China generally is less liquid and accessible to foreign investors than corresponding markets in more developed economies, the Fund intends to achieve exposure to currency markets in China using a variety of investments and investment techniques. For example, the Fund will invest in short-term U.S. money market securities and forward currency contracts and currency swaps that settle in U.S. dollars. The combination of U.S. money market securities and forward currency contracts and swaps is designed to provide exposure equivalent to money market securities denominated in Chinese yuan. A forward currency contract is an agreement to buy or sell a specific currency at a future date at a price set at the time of the contract. A currency swap is an agreement between two parties to exchange one currency for another at a future rate. The Fund also will invest in money market securities and other instruments, including forward currency contracts and swaps, denominated in Chinese yuan that trade and settle in Hong Kong and other markets outside of mainland China. The market for these yuan-denominated instruments is sometimes referred to as the &amp;#8220;CNH market.&amp;#8221; Eligible yuan-denominated investments include time deposits of commercial banks, short-term corporate debt, short-term debt issued by the government of China (including its agencies and instrumentalities), as well as short-term debt issued by supranational organizations (such as the International Bank for Reconstruction and Development). The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. A repurchase agreement is  a transaction in which the Fund purchases securities or other obligations from a bank or securities dealer and simultaneously commits to resell them to a counterparty at an agreed-upon date or upon demand and at a price reflecting a market rate of interest unrelated to the coupon rate or maturity of the purchased obligations.&lt;br /&gt;&lt;br /&gt;The Fund generally will maintain a weighted average portfolio maturity of 90 days or less with respect to the money market securities in its portfolio. Forward currency contracts and swaps generally will be kept to an average term of six months or less.  &lt;br /&gt;&lt;br /&gt;The Fund will invest, under normal circumstances, at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in investments whose combined performance is economically tied to China. If subsequent to an investment, the 80% requirement is no longer met, the Fund&amp;#8217;s future investments will be made in a manner that will bring the Fund into compliance with this policy. The Trust will provide shareholders with sixty (60) days&amp;#8217; prior notice of any change to this policy for the Fund.</rr:StrategyNarrativeTextBlock>
  <rr:RiskNarrativeTextBlock contextRef="Duration_02Jan2012_01Jan2013S000021353_Member">You can lose money on your investment in the Fund. The Fund is subject to the risks described below. Some or all of these risks may adversely affect the Fund&amp;#8217;s net asset value per share (&amp;#8220;NAV&amp;#8221;), trading price, yield, total return and/or ability to meet its objective.&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;&lt;b&gt;Investment Risk.&lt;/b&gt; As with all investments, an investment in the Fund is subject to investment risk.

The Fund&amp;#8217;s NAV and market price may fluctuate significantly within a wide range in response to these factors. As a result, an investor could lose money over short or long periods of time.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;&lt;b&gt;Shares of the Fund May Trade at Prices Other Than NAV.&lt;/b&gt; Although it is expected that the market price of the shares of the Fund will approximate the Fund&amp;#8217;s NAV when purchased and sold in the secondary market, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;&lt;b&gt;Capital Controls Risk.&lt;/b&gt; Economic conditions, such as volatile currency exchange rates and interest rates, political events and other conditions may, without prior warning, lead to foreign government intervention and the imposition of &amp;#8220;capital controls.&amp;#8221; Capital controls include the prohibition of, or restrictions on, the ability to transfer currency, securities or other assets. Capital controls may impact the ability of the Fund to buy, sell or otherwise transfer securities or currency, adversely affect the trading market and price for shares of the Fund, and cause the Fund to decline in value.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;&lt;b&gt;Cash Redemption Risk.&lt;/b&gt; The Fund&amp;#8217;s investment strategy will require it to effect redemptions, in whole or in part, for cash. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used exclusively.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;&lt;b&gt;Counterparty and Issuer Credit Risk.&lt;/b&gt; The financial condition of an issuer of a debt security or other instrument or a counterparty to a derivative or other contract may cause such issuer or counterparty to default, become unable to pay interest or principal due or otherwise fail to honor its obligations. While the Fund attempts to limit credit and counterparty exposure in a manner consistent with its investment objective, the value of an investment in the Fund may change quickly and without warning in response to issuer or counterparty defaults and changes in the credit ratings of the Fund&amp;#8217;s portfolio investments.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;&lt;b&gt;CNH Market Risk.&lt;/b&gt; While the CNH market is expected to continue to grow, it is relatively new and may not be as liquid as more established markets. In light of this, the Fund intends to manage its exposure to the CNH market in a prudent manner consistent with its investment objective.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;&lt;b&gt;Currency Exchange Rate Risk.&lt;/b&gt; The Fund invests a significant portion of its assets in investments denominated in Chinese yuan, or in securities that provide exposure to Chinese yuan, currency exchange rates or interest rates denominated in Chinese yuan. Changes in currency exchange rates and the relative value of the Chinese yuan will affect the value of the Fund&amp;#8217;s investment and the value of your Fund shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;&lt;b&gt;Derivatives Investment Risk.&lt;/b&gt; The Fund will invest in derivatives. Derivatives are subject to a number of risks described elsewhere in this Prospectus, such as interest rate risk, market risk, and credit risk. They also involve the risk that changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, or that the  counterparty to a derivative contract might default on its obligations. Derivatives can be volatile and may be less liquid than other securities. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;&lt;b&gt;Emerging Markets Risk.&lt;/b&gt; Investments in securities and instruments traded in developing or emerging markets, or that provide exposure to such securities or markets, can involve additional risks relating to political, economic, or regulatory conditions not associated with investments in U.S. securities and instruments or investments in more developed international markets. Such conditions may impact the ability of the Fund to buy, sell or otherwise transfer securities, adversely affect the trading market and price for Fund shares, and cause the Fund to decline in value.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;&lt;b&gt;Foreign Securities Risk.&lt;/b&gt; The Fund invests a significant portion of its assets in non-U.S. securities and instruments, or in securities that provide exposure to such instruments. Investments in non-U.S. securities and instruments involve certain risks that may not be present with investments in U.S. securities, including the risk of loss due to foreign currency fluctuations or to political or economic instability.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;&lt;b&gt;Geographic Concentration in China.&lt;/b&gt; Because the Fund concentrates its investments in China, the Fund&amp;#8217;s performance is expected to be closely tied to social, political, and economic conditions within China and to be more volatile than the performance of more geographically diversified funds. The government of China maintains strict currency controls in order to achieve economic, trade and political objectives and regularly intervenes in the currency market. The Chinese government places strict regulation on the yuan and manages the yuan so that it has historically traded in a tight range relative to the U.S. dollar. The Chinese government has been under pressure to manage the currency in a less restrictive fashion so that it is less correlated to the U.S. dollar. It is expected that such action would increase the value of the yuan relative to the U.S. dollar. Of course, there can be no guarantee that this will occur, or that the yuan will move in relation to the U.S. dollar as expected. These and other factors could have a negative impact on the Fund&amp;#8217;s performance and increase the volatility of an investment in the Fund.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;&lt;b&gt;Interest Rate Risk.&lt;/b&gt; Interest rate risk is the risk that fixed income securities will decline in value because of changes in interest rates and other factors, such as perception of an issuer&amp;#8217;s creditworthiness.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;&lt;b&gt;Issuer-Specific Risk.&lt;/b&gt; Issuer-specific events, including changes in the financial condition of an issuer, can have a negative impact on the value of the Fund.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;&lt;b&gt;Management Risk.&lt;/b&gt; The Fund is actively managed using proprietary investment strategies and processes. There can be no guarantee that these strategies and processes will be successful or that the Fund will achieve its investment objective.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;&lt;b&gt;Non-Diversification Risk.&lt;/b&gt; The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. To the extent the Fund invests a significant percentage of its assets in a limited number of issuers, the Fund is subject to the risks of investing in those few issuers, and may be more susceptible to a single adverse economic or regulatory occurrence. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;&lt;b&gt;Offshore Investor Risk.&lt;/b&gt; In addition to the general risks associated with investing in non-U.S. currencies and non-U.S. currency markets, there are special risks associated with investing in Chinese yuan or securities designed to provide exposure to Chinese yuan. The government of China maintains strict currency controls in support of economic, trade and political objectives and regularly intervenes in the currency market. The government&amp;#8217;s actions may not be transparent or predictable. As a result, the value of the yuan, and the value of securities designed to provide exposure to the yuan, can change quickly and arbitrarily. Furthermore, it is difficult for offshore investors to directly access money market securities in China because of investment and trading restrictions. These limitations and restrictions may impact the availability, liquidity, and pricing of securities designed to provide offshore investors with exposure to Chinese markets. As a result, returns achieved by offshore investors, such as the Fund, could differ from those available to domestic investors in China.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;&lt;b&gt;Repurchase Agreement Risk.&lt;/b&gt; The Fund&amp;#8217;s investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left: -20px"&gt;&lt;b&gt;Sovereign Debt Risk.&lt;/b&gt; Bonds issued by governments, sometimes referred to as &amp;#8220;sovereign&amp;#8221; debt, present risks not associated with investments in other types of bonds. The government or agency issuing the debt may be unable or unwilling to make interest payments and/or repay the principal owed. In such instance, the Fund may have limited recourse against the issuing government or agency. In the past, governments of emerging market countries have refused to honor their payment obligations on issued bonds.&lt;/li&gt;&lt;/ul&gt;</rr:RiskNarrativeTextBlock>

  <rr:StrategyNarrativeTextBlock contextRef="Duration_02Jan2012_01Jan2013S000028136_Member">The Fund is designed to provide exposure to both the currencies and money market rates available to foreign investors in selected commodity-producing countries. The term &amp;#8220;commodity currency&amp;#8221; generally is used to describe the currency of a country whose economic success is commonly identified with the production and export of commodities (such as precious metals, oil, agricultural products or other raw materials) and whose value is closely linked to the value of such commodities. As the demand for, or price of, such commodities increases, money tends to flow into the country. This generally lifts the country&amp;#8217;s economic prospects and supports the value of its currency. Conversely, declines in the demand for, or value of, such commodities historically have contributed to declines in the relative value of these countries&amp;#8217; currencies.&lt;br/&gt;&lt;br/&gt;The Fund intends to invest in commodity-producing countries, such as Australia, Brazil, Canada, Chile, Colombia, Indonesia, Malaysia, New Zealand, Norway, Peru, Russia and South Africa. This list may change based on market developments. In addition to seeking broad exposure across countries and currencies, the Fund intends to seek exposure across currencies correlated to each of the key commodity groups: industrial metals, precious metals, energy, agriculture and livestock. The Fund generally will invest only in currencies that &amp;#8220;float&amp;#8221; relative to other currencies. The value of a floating currency is largely determined by supply and demand and prevailing market rates. In contrast, the value of a &amp;#8220;fixed&amp;#8221; currency generally is set by a government or central bank at an official exchange rate. The Fund generally does not intend to invest in the currencies of notable commodity producers, such as Saudi Arabia and the United Arab Emirates, since they are fixed or otherwise closely linked to the U.S. dollar. The Fund will only invest in currencies that it deems to be sufficiently liquid and accessible. &lt;br/&gt;&lt;br/&gt;The Fund is an actively managed exchange traded fund (&amp;#8220;ETF&amp;#8221;) that seeks to achieve exposure to money market rates of selected commodity-producing countries by investing primarily in short-term U.S. money market securities, forward currency contracts, currency swaps and interest rate swaps. The combination of money market securities with forward currency contracts and interest rate and currency swaps is designed to provide exposure equivalent to money market securities denominated in a non-U.S. currency. A forward currency contract is an agreement to buy or sell a specific currency at a future date at a price set at the time of the contract. An interest rate swap involves the exchange of a floating interest rate payment for a fixed interest payment. A currency swap is an agreement between two parties to exchange one currency for another at a future rate. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. A repurchase agreement is a transaction in which the Fund purchases securities or other obligations from a bank or securities dealer and simultaneously commits to resell them to a counterparty at an agreed-upon date or upon demand and at a price reflecting a market rate of interest unrelated to the coupon rate or maturity of the purchased obligations. &lt;br/&gt;&lt;br/&gt;In order to reduce interest rate risk, the Fund generally expects to maintain an average portfolio maturity of 90 days or less. The &amp;#8220;average portfolio maturity&amp;#8221; of the Fund is the average of all the current maturities of the individual securities in the Fund&amp;#8217;s portfolio. Average portfolio maturity is important to investors as an indication of the Fund&amp;#8217;s sensitivity to changes in interest rates. Funds with longer portfolio maturities generally are subject to greater interest rate risk. All money market securities acquired by the Fund will be rated in the upper two short-term ratings by at least two nationally recognized statistical rating organizations (&amp;#8220;NRSROs&amp;#8221;) or, if unrated, deemed to be of equivalent quality. &lt;br/&gt;&lt;br/&gt;The Fund will invest, under normal circumstances, at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in investments whose combined performance is tied economically to selected commodity-producing countries. If, subsequent to an investment, the 80% requirement is no longer met, the Fund&amp;#8217;s future investments will be made in a manner that will bring the Fund into compliance with this policy. The Trust will provide shareholders with sixty (60) days&amp;#8217; prior notice of any change to this policy for the Fund.</rr:StrategyNarrativeTextBlock>
  <rr:RiskNarrativeTextBlock contextRef="Duration_02Jan2012_01Jan2013S000028136_Member">You can lose money on your investment in the Fund. The Fund is subject to the risks described below. Some or all of these risks may adversely affect the Fund&amp;#8217;s net asset value per share (&amp;#8220;NAV&amp;#8221;), trading price, yield, total return and/or ability to meet its objectives.&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Investment Risk.&lt;/b&gt; As with all investments, an investment in the Fund is subject to investment risk. Investors in the Fund could lose money, including the possible loss of the entire principal amount of an investment, over short or long periods of time.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Market Risk.&lt;/b&gt; The trading prices of currencies, fixed income securities and other instruments fluctuate in response to a variety of factors. The Fund&amp;#8217;s NAV and market price may fluctuate significantly in response to these factors. As a result, an investor could lose money over short or long periods of time.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Shares of the Fund May Trade at Prices Other Than NAV.&lt;/b&gt; Although it is expected that the market price of the shares of the Fund will approximate the Fund&amp;#8217;s NAV when purchased and sold in the secondary market, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Cash Redemption Risk.&lt;/b&gt; The Fund&amp;#8217;s investment strategy will require it to effect redemptions, in whole or in part, for cash. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used exclusively.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Commodity Country Risk.&lt;/b&gt; The Fund invests a significant portion of its assets in investments designed to provide exposure to both the currencies and money market rates available to foreign investors in selected commodity-producing countries. Commodity-producing countries are vulnerable to the volatility in the demand for commodities. Declines in demand for commodities produced by a particular country may occur quickly and without warning and may negatively impact the value of the Fund and your investment.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Counterparty and Issuer Credit Risk.&lt;/b&gt; The financial condition of an issuer of a debt security or other instrument or a counterparty to a derivative or other contract may cause such issuer or counterparty to default, become unable to pay interest or principal due or otherwise fail to honor its obligations. While the Fund attempts to limit credit and counterparty exposure in a manner consistent with its investment objective, the value of an investment in the Fund may change quickly and without warning in response to issuer or counterparty defaults and changes in the credit ratings of the Fund&amp;#8217;s portfolio investments.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Currency Exchange Rate Risk.&lt;/b&gt; The Fund invests a significant portion of its assets in investments denominated in non-U.S. currencies, or in securities that provide exposure to such currencies, currency exchange rates or interest rates denominated in such currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund&amp;#8217;s investment and the value of your Fund shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Derivatives Investment Risk.&lt;/b&gt; The Fund will invest in derivatives. Derivatives are subject to a number of risks described elsewhere in this Prospectus, such as interest rate risk, market risk, and credit risk. They also involve the risk that changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, or that the counterparty to a derivative contract might default on its obligations. Derivatives can be volatile and may be less liquid than other securities. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Emerging Markets Risk.&lt;/b&gt; Investments in securities and instruments traded in developing or emerging markets, or that provide exposure to such securities or markets, can involve additional risks relating to political, economic, or regulatory conditions not associated with investments in U.S. securities and instruments or investments in more developed international markets. For example, developing or emerging market governments may, without prior warning, impose capital controls on the ability to transfer currency, securities or other assets. The Fund&amp;#8217;s ability to access certain developing or emerging markets also may be limited due to a variety of factors, including currency convertibility issues. Such conditions may impact the ability of the Fund to buy, sell or otherwise transfer securities or currency, cause the Fund&amp;#8217;s returns to differ from those available to domestic investors, adversely affect the trading market and price for Fund shares, and cause the Fund to decline in value.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Foreign Securities Risk.&lt;/b&gt; The Fund invests a significant portion of its assets in non-U.S. securities and instruments, or in securities that provide exposure to such instruments. Investments in non-U.S. securities and instruments involve certain risks that may not be present with investments in U.S. securities, including the risk of loss due to foreign currency fluctuations or to political or economic instability.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Interest Rate Risk.&lt;/b&gt; Interest rate risk is the risk that fixed income securities will decline in value because of changes in interest rates and other factors, such as perception of an issuer&amp;#8217;s creditworthiness.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Issuer-Specific Risk.&lt;/b&gt; Issuer-specific events, including changes in the financial condition of an issuer, can have a negative impact on the value of the Fund.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Management Risk.&lt;/b&gt; The Fund is actively managed using proprietary investment strategies and processes. There can be no guarantee that these strategies and processes will be successful or that the Fund will achieve its investment objective.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Non-Diversification Risk.&lt;/b&gt; The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. To the extent the Fund invests a significant percentage of its assets in a limited number of issuers, the Fund is subject to the risks of investing in those few issuers, and may be more susceptible to a single adverse economic or regulatory occurrence. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Repurchase Agreement Risk.&lt;/b&gt; The Fund&amp;#8217;s investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term. &lt;/li&gt;&lt;/ul&gt;</rr:RiskNarrativeTextBlock>

  <rr:RiskNarrativeTextBlock contextRef="Duration_02Jan2012_01Jan2013S000021346_Member">You can lose money on your investment in the Fund. The Fund is subject to the risks described below. Some or all of these risks may adversely affect the Fund&amp;#8217;s net asset value per share (&amp;#8220;NAV&amp;#8221;), trading price, yield, total return and/or ability to meet its objective.&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Investment Risk.&lt;/b&gt; As with all investments, an investment in the Fund is subject to investment risk. Investors in the Fund could lose money, including the possible loss of the entire principal amount of an investment, over short or long periods of time.&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Market Risk.&lt;/b&gt; The trading prices of currencies, fixed income securities and other instruments fluctuate in response to a variety of factors. The Fund&amp;#8217;s NAV and market price may fluctuate significantly in response to these factors. As a result, an investor could lose money over short or long periods of time.&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Shares of the Fund May Trade at Prices Other Than NAV.&lt;/b&gt; Although it is expected that the market price of the shares of the Fund will approximate the Fund&amp;#8217;s NAV when purchased and sold in the secondary market, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Cash Redemption Risk.&lt;/b&gt; The Fund&amp;#8217;s investment strategy will require it to effect redemptions, in whole or in part, for cash. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used exclusively.&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Counterparty and Issuer Credit Risk.&lt;/b&gt; The financial condition of an issuer of a debt security or other instrument or a counterparty to a derivative or other contract may cause such issuer or counterparty to default, become unable to pay interest or principal due or otherwise fail to honor its obligations. While the Fund attempts to limit credit and counterparty exposure in a manner consistent with its investment objective, the value of an investment in the Fund may change quickly and without warning in response to issuer or counterparty defaults and changes in the credit ratings of the Fund&amp;#8217;s portfolio investments.&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Currency Exchange Rate Risk.&lt;/b&gt; The Fund invests a significant portion of its assets in investments denominated in non-U.S. currencies, or in securities that provide exposure to such currencies, currency exchange rates or interest rates denominated in such currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund&amp;#8217;s investment and the value of your Fund shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Derivatives Investment Risk.&lt;/b&gt; The Fund will invest in derivatives. Derivatives are subject to a number of risks described elsewhere in this Prospectus, such as interest rate risk, market risk, and credit risk. They also involve the risk that changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, or that the counterparty to a derivative contract might default on its obligations. Derivatives can be volatile and may be less liquid than other securities. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Emerging Markets Risk.&lt;/b&gt; Investments in securities and instruments traded in developing or emerging markets, or that provide exposure to such securities or markets, can involve additional risks relating to political, economic, or regulatory conditions not associated with investments in U.S. securities and instruments or investments in more developed international markets. For example, developing or emerging market governments may, without prior warning, impose capital controls on the ability to transfer currency, securities or other assets. The Fund&amp;#8217;s ability to access certain developing or emerging markets also may be limited due to a variety of factors, including currency convertibility issues. Such conditions may impact the ability of the Fund to buy, sell or otherwise transfer securities or currency, cause the Fund&amp;#8217;s returns to differ from those available to domestic investors, adversely affect the trading market and price for Fund shares, and cause the Fund to decline in value.&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Foreign Securities Risk.&lt;/b&gt; The Fund invests a significant portion of its assets in non-U.S. securities and instruments, or in securities that provide exposure to such instruments. Investments in non-U.S. securities and instruments involve certain risks that may not be present with investments in U.S. securities, including the risk of loss due to foreign currency fluctuations or to political or economic instability.&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Interest Rate Risk.&lt;/b&gt; Interest rate risk is the risk that fixed income securities will decline in value because of changes in interest rates and other factors, such as perception of an issuer&amp;#8217;s creditworthiness.&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Issuer-Specific Risk.&lt;/b&gt; Issuer-specific events, including changes in the financial condition of an issuer, can have a negative impact on the value of the Fund.&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Management Risk. &lt;/b&gt;The Fund is actively managed using proprietary investment strategies and processes. There can be no guarantee that these strategies and processes will be successful or that the Fund will achieve its investment objective.&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Non-Diversification Risk. &lt;/b&gt;The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. To the extent the Fund invests a significant percentage of its assets in a limited number of issuers, the Fund is subject to the risks of investing in those few issuers, and may be more susceptible to a single adverse economic or regulatory occurrence. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.&lt;/li&gt;&lt;/ul&gt; &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Repurchase Agreement Risk.&lt;/b&gt; The Fund&amp;#8217;s investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term.&lt;/li&gt;&lt;/ul&gt;</rr:RiskNarrativeTextBlock>

  <rr:StrategyNarrativeTextBlock contextRef="Duration_02Jan2012_01Jan2013S000030945_Member">The Fund seeks to achieve its investment objective through investment in Local Debt denominated in the currencies of a broad range of Asian countries. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in Local Debt. For these purposes, Local Debt includes fixed income securities, such as bonds, notes or other debt obligations, denominated in local currencies of countries in Asia, as well as certain derivatives and other instruments described herein. The Fund is an actively managed exchange traded fund (&amp;#8220;ETF&amp;#8221;).&lt;br/&gt;&lt;br/&gt;The Fund intends to focus its investments on bonds and other debt instruments issued by governments (national, state, and local), government agencies and instrumentalities, and government sponsored enterprises. The Fund also may invest in Local Debt issued by supranational organizations such as the European Investment Bank, Asian Development Bank, International Bank for Reconstruction and Development or International Finance Corporation, and development agencies supported by other national governments. The Fund may invest in corporate bonds economically tied to Asian countries. The Fund also may invest in inflation-linked fixed income securities denominated in Asian currencies.&lt;br/&gt;&lt;br/&gt;The Fund intends to provide exposure to developing/emerging market economies in Asia. Specifically, the Fund intends to invest in Local Debt primarily from China, Hong Kong, India, Indonesia, Malaysia, the Philippines, Singapore, South Korea, Taiwan, Thailand, and Vietnam. The Fund is permitted to invest in developed market economies, such as Australia and New Zealand. This list may change based on market developments. The Fund uses a structured investment approach that analyzes multiple factors. Countries are grouped into differentiated tiers based on an analysis of these factors. Subject to the Fund&amp;#8217;s general investment requirement to provide broad country exposure within the region, the Fund generally invests a higher  percentage of its assets in countries that have larger and more liquid debt markets and that the Fund&amp;#8217;s adviser believes are pursuing sustainable fiscal and monetary policies in light of economic and market conditions. The country exposures are consistently monitored from a risk perspective and may be modified, reduced or eliminated. The Fund&amp;#8217;s exposure to any single country generally will be limited to 20% of the Fund&amp;#8217;s assets. The percentage of Fund assets invested in a specific region, country or issuer will change from time to time.&lt;br/&gt;&lt;br/&gt;The universe of Local Debt currently includes securities that are rated &amp;#8220;investment grade&amp;#8221; as well as &amp;#8220;non-investment grade.&amp;#8221; The Fund intends to provide a broad-based exposure to Local Debt and therefore will invest in both investment grade and non-investment grade securities. Securities rated investment grade generally are considered to be of higher credit quality and subject to lower default risk. Although securities rated below investment grade may offer the potential for higher yields, they generally are subject to a higher potential risk of loss.&lt;br/&gt;&lt;br/&gt;The Fund attempts to limit interest rate risk by maintaining an aggregate portfolio duration of between two and eight years under normal market conditions. Aggregate portfolio duration is important to investors as an indication of the Fund&amp;#8217;s sensitivity to changes in interest rates. Funds with higher durations generally are subject to greater interest rate risk. For example, the value of a fund with a portfolio duration of ten years would be expected to drop by 10% for every 1% increase in interest rates. The Fund&amp;#8217;s actual portfolio duration may be longer or shorter depending on market conditions. The Fund may also invest in short-term money market securities denominated in the currencies of countries in which the Fund invests.&lt;br/&gt;&lt;br/&gt;The Fund may invest up to 30% of its net assets in derivatives such as forward currency contracts and swaps. The Fund&amp;#8217;s use of forward contracts and swaps will be underpinned by investments in cash or other liquid assets (typically short-term, high-quality U.S. money market securities) and is designed to provide exposure similar to investments in local currency debt. The Fund does not use derivatives to enhance leverage. A forward contract is an agreement to buy or sell a specific currency at a future date at a price set at the time of the contract. A swap is an agreement between two parties to exchange payments based on a reference asset, which may be a currency or rate, but also may be a single asset, a pool of assets or an index of assets. The Fund also may enter into repurchase agreements designed to result in a fixed rate of return for the Fund insulated from market fluctuations during the holding period. The Fund will enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. A repurchase agreement is a transaction in which the Fund purchases securities or other obligations from a bank or securities dealer and simultaneously commits to resell them to a counterparty at an agreed-upon date or upon demand and at a price reflecting a market rate of interest unrelated to the coupon rate or maturity of the purchased obligations. A futures contract may generally be described as an agreement for the future sale by one party and the purchase by another of a specified security or instrument at a specified price and time. The Fund may invest in interest rate and other futures contracts listed for trading on exchanges in Asia. Assets not invested in Local Debt generally will be invested in U.S. government securities and investment grade money market instruments. The Fund may invest up to 20% of its assets in debt instruments denominated in U.S. dollars issued by Asian governments and government sponsored enterprises.&lt;br/&gt;&lt;br/&gt;The decision to secure exposure through direct investment in bonds or indirectly through derivative transactions will be a function of, among other things, market accessibility, credit exposure, tax ramifications and regulatory requirements applicable to U.S. investment companies. If, subsequent to an investment, the 80% requirement is no longer met, the Fund&amp;#8217;s future investments will be made in a manner that will bring the Fund into compliance with this policy. The Trust will provide shareholders with sixty (60) days&amp;#8217; prior notice of any change to this policy for the Fund.</rr:StrategyNarrativeTextBlock>

Some or all of these risks may adversely affect the Fund&amp;#8217;s net asset value per share (&amp;#8220;NAV&amp;#8221;), trading price, yield, total return and/or ability to meet its objectives.&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Investment Risk.&lt;/b&gt; As with all investments, an investment in the Fund is subject to investment risk. Investors in the Fund could lose money, including the possible loss of the entire principal amount of an investment, over short or long periods of time.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Market Risk.&lt;/b&gt; The trading prices of currencies, fixed income securities and other instruments fluctuate in response to a variety of factors. The Fund&amp;#8217;s NAV and market price may fluctuate significantly in response to these factors. As a result, an investor could lose money over short or long periods of time.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Shares of the Fund May Trade at Prices Other Than NAV.&lt;/b&gt; Although it is expected that the market price of the shares of the Fund will approximate the Fund&amp;#8217;s NAV when purchased and sold in the secondary market, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Cash Redemption Risk.&lt;/b&gt; The Fund&amp;#8217;s investment strategy will require it to effect redemptions, in whole or in part, for cash, triggering security sales. The sale of non-U.S. denominated securities can generate realized foreign exchange losses which could impact the income distributions paid by the Fund. Additionally, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used exclusively.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Counterparty and Issuer Credit Risk.&lt;/b&gt; The financial condition of an issuer of a debt security or other instrument or a counterparty to a derivative or other contract may cause such issuer or counterparty to default, become unable to pay interest or principal due or otherwise fail to honor its obligations. While the Fund attempts to limit credit and counterparty exposure in a manner consistent with its investment objective, the value of an investment in the Fund may change quickly and without warning in response to issuer or counterparty defaults and changes in the credit ratings of the Fund&amp;#8217;s portfolio investments.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Currency Exchange Rate Risk.&lt;/b&gt; The Fund invests a significant portion of its assets in investments denominated in non-U.S. currencies, or in securities that provide exposure to such currencies, currency exchange rates or interest rates denominated in such currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund&amp;#8217;s investment and the value of your Fund shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Derivatives Investment Risk.&lt;/b&gt; The Fund will invest in derivatives. Derivatives are subject to a number of risks described elsewhere in this Prospectus, such as interest rate risk, market risk, and credit risk. They also involve the risk that changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, or that the counterparty to a derivative contract might default on its obligations. Derivatives can be volatile and may be less liquid than other securities. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Emerging Markets Risk.&lt;/b&gt; Investments in securities and instruments traded in developing or emerging markets, or that provide exposure to such securities or markets, can involve additional risks relating to political, economic, or regulatory conditions not associated with investments in U.S. securities and instruments or investments in more developed international markets. For example, developing or emerging market governments may, without prior warning, impose capital controls on the ability to transfer currency, securities or other assets. The Fund&amp;#8217;s ability to access certain developing or emerging markets also may be limited due to a variety of factors, including currency convertibility issues. Such conditions may impact the ability of the Fund to buy, sell or otherwise transfer securities or currency, cause the Fund&amp;#8217;s returns to differ from those available to domestic investors, adversely affect the trading market and price for Fund shares, and cause the Fund to decline in value.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Foreign Securities Risk.&lt;/b&gt; The Fund invests a significant portion of its assets in non-U.S. securities and instruments, or in securities that provide exposure to such instruments. Investments in non-U.S. securities and instruments involve certain risks that may not be present with investments in U.S. securities, including the risk of loss due to foreign currency fluctuations or to political or economic instability.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;High Yield Securities Risk.&lt;/b&gt; Higher yielding, high risk debt securities, sometimes referred to as junk bonds, may present additional risk because these securities may be less liquid and present more credit risk than investment grade bonds. The price of high yield securities tends to be more susceptible to issuer-specific operating results and outlook and to real or perceived adverse economic and competitive industry conditions.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Interest Rate Risk.&lt;/b&gt; Interest rate risk is the risk that fixed income securities will decline in value because of changes in interest rates and other factors, such as perception of an issuer&amp;#8217;s creditworthiness.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Investment in Asia Risk.&lt;/b&gt; The Fund&amp;#8217;s investments will have significant exposure to Asia. As a result, the Fund will be susceptible to loss due to adverse market, political, regulatory, and geographic events affecting that region. A variety of factors, including currency devaluations, may impact the ability of the Fund to buy, sell or otherwise transfer securities, adversely affect the trading market and price for Fund shares and cause the Fund to decline in value.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Issuer-Specific Risk.&lt;/b&gt; Issuer-specific events, including changes in the financial condition of an issuer, can have a negative impact on the value of the Fund.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Management Risk.&lt;/b&gt; The Fund is actively managed using proprietary investment strategies and processes.

  <rr:RiskNarrativeTextBlock contextRef="Duration_02Jan2012_01Jan2013S000033843_Member">You can lose money on your investment in the Fund. The Fund is subject to the risks described below. Some or all of these risks may adversely affect the Fund&amp;#8217;s net asset value per share (&amp;#8220;NAV&amp;#8221;), trading price, yield, total return and/or ability to meet its objective. &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Investment Risk.&lt;/b&gt; As with all investments, an investment in the Fund is subject to investment risk. Investors in the Fund could lose money, including the possible loss of the entire principal amount of an investment, over short or long periods of time.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Market Risk.&lt;/b&gt; The trading prices of currencies, fixed income securities and other instruments fluctuate in response to a variety of factors. The Fund&amp;#8217;s NAV and market price may fluctuate significantly in response to these factors. As a result, an investor could lose money over short or long periods of time.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Shares of the Fund May Trade at Prices Other Than NAV.&lt;/b&gt; Although it is expected that the market price of the shares of the Fund will approximate the Fund&amp;#8217;s NAV when purchased and sold in the secondary market, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.&lt;/li&gt;&lt;/ul&gt;   &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Capital Controls Risk.&lt;/b&gt; Economic conditions, such as volatile currency exchange rates and interest rates, political events and other conditions may, without prior warning, lead to government intervention and the imposition of &amp;#8220;capital controls.&amp;#8221; Capital controls may impact the ability of the Fund to buy, sell or otherwise transfer securities or currency, adversely affect the trading market and price for shares of the Fund, and cause the Fund to decline in value.&lt;/li&gt;&lt;/ul&gt;  &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Cash Redemption Risk.&lt;/b&gt; The Fund&amp;#8217;s investment strategy will require it to effect redemptions, in whole or in part, for cash, triggering security sales. The sale of non-U.S. denominated securities can generate realized foreign exchange losses which could impact the income distributions paid by the Fund. Additionally, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used exclusively. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Counterparty and Issuer Credit Risk.&lt;/b&gt; The financial condition of an issuer of a debt security or other instrument or a counterparty to a derivative or other contract may cause such issuer or counterparty to default, become unable to pay interest or principal due or otherwise fail to honor its obligations. While the Fund attempts to limit credit and counterparty exposure in a manner consistent with its investment objective, the value of an investment in the Fund may change quickly and without warning in response to issuer or counterparty defaults and changes in the credit ratings of the Fund&amp;#8217;s portfolio investments.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Currency Exchange Rate Risk.&lt;/b&gt; While the Fund intends to focus its investment on Corporate Debt denominated in U.S. dollars, the Fund may invest a portion of its assets in investments denominated in non-U.S. currencies, or in securities that provide exposure to such currencies, currency exchange rates or interest rates denominated in such currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund&amp;#8217;s investment and the value of your Fund shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.&lt;/li&gt;&lt;/ul&gt;  &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Derivatives Investment Risk.&lt;/b&gt; The Fund may invest in derivatives. Derivatives are subject to a number of risks described elsewhere in the Fund&amp;#8217;s Prospectus, such as credit risk, interest rate risk, and market risk. They also involve the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. The counterparty to a derivative contract might default on its obligations. Derivatives can be volatile and may be less liquid than other securities. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.&lt;/li&gt;&lt;/ul&gt;  &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Emerging Markets Risk.&lt;/b&gt; Investments in securities and instruments traded in developing or emerging markets, or that provide exposure to such securities or markets, can involve additional risks relating to political, economic, or regulatory conditions not associated with investments in U.S. securities and instruments or investments in more developed international markets. For example, developing or emerging market governments may, without prior warning, impose capital controls on the ability to transfer currency, securities or other assets. The Fund&amp;#8217;s ability to access certain developing or emerging markets also may be limited due to a variety of factors, including currency convertibility issues. Such conditions may impact the ability of the Fund to buy, sell or otherwise transfer securities, cause the Fund&amp;#8217;s returns to differ from those available to domestic investors, adversely affect the trading market and price for Fund shares, and cause the Fund to decline in value.&lt;/li&gt;&lt;/ul&gt;   &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;High Yield Securities Risk.&lt;/b&gt; Higher yielding, high risk debt securities, sometimes referred to as &amp;#8220;junk bonds&amp;#8221;, may present additional risk because these securities may be less liquid and present more credit risk than investment grade bonds. The price of high yield securities tends to be more susceptible to issuer-specific operating results and outlook and to real or perceived adverse economic and competitive industry conditions.&lt;/li&gt;&lt;/ul&gt;  &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Interest Rate Risk.&lt;/b&gt; Interest rate risk is the risk that fixed income securities will decline in value because of increases in interest rates and other factors, such as perception of an issuer&amp;#8217;s creditworthiness.&lt;/li&gt;&lt;/ul&gt;   &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Issuer-Specific Risk.&lt;/b&gt; Issuer-specific events, including changes in the financial condition of an issuer, can have a negative impact on the value of the Fund.&lt;/li&gt;&lt;/ul&gt;  &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Management Risk.&lt;/b&gt; The Fund is actively managed using proprietary investment strategies and processes. There can be no guarantee that these strategies and processes will be successful or that the Fund will achieve its investment objective.&lt;/li&gt;&lt;/ul&gt;  &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Non-Diversification Risk.&lt;/b&gt; The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. To the extent the Fund invests a significant percentage of its assets in a limited number of issuers, the Fund is subject to the risks of investing in those few issuers, and may be more susceptible to a single adverse economic or regulatory occurrence. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.&lt;/li&gt;&lt;/ul&gt;   &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Repurchase Agreement Risk.&lt;/b&gt; The Fund&amp;#8217;s investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be  subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term.&lt;/li&gt;&lt;/ul&gt;   &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Sovereign Debt Risk.&lt;/b&gt; Bonds issued by governments, sometimes referred to as &amp;#8220;sovereign&amp;#8221; debt, present risks not associated with investments in other types of bonds. The government or agency issuing the debt may be unable or unwilling to make interest payments and/or repay the principal owed.

  <rr:StrategyNarrativeTextBlock contextRef="Duration_02Jan2012_01Jan2013S000021343_Member">The Fund seeks to achieve its investment objective through investment in Debt Securities denominated in Australian or New Zealand dollars. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in Debt Securities. For these purposes, Debt Securities include fixed income securities, such as bonds, notes or other debt obligations, denominated in Australian or New Zealand dollars, as well as certain derivatives and other instruments described herein. The Fund is an actively managed exchange traded fund (&amp;#8220;ETF&amp;#8221;). &lt;br/&gt;&lt;br/&gt;The Fund intends to focus its investments on bonds and other debt instruments denominated in Australian and New Zealand dollars issued by governments (national, state and local), government agencies and instrumentalities, government-sponsored enterprises and supranational organizations. For these purposes, &amp;#8220;supranational organizations&amp;#8221; include entities such as the European Investment Bank, International Bank for Reconstruction and Development, International Finance Corporation, and other regional development banks. The Fund also may invest in Debt Securities of corporate issuers, although this is not expected to be a focus of the Fund. &lt;br/&gt;&lt;br/&gt;The Fund is designed to provide broad exposure to Debt Securities of issuers in Australia and New Zealand. The Fund uses a structured investment approach to allocate its investments between countries (Australia and New Zealand) and sectors (government debt, semi-government debt, supranational organizations). &amp;#8220;Government debt&amp;#8221; refers to Debt Securities issued by the Commonwealth of Australia or New Zealand and its various agencies, instrumentalities and government-sponsored enterprises. &amp;#8220;Semi-government debt&amp;#8221; refers to Debt Securities issued by the local, state and territory governments of Australia typically to finance local infrastructure and operations. As noted, &amp;#8220;supranational organizations&amp;#8221; include entities such as the International Bank for Reconstruction and Development and other regional development banks. The Fund&amp;#8217;s exposure to  Australia and New Zealand is based on the relative gross domestic product, or &amp;#8220;GDP,&amp;#8221; of each country. Since Australia&amp;#8217;s economy is much larger than New Zealand&amp;#8217;s, the Fund&amp;#8217;s exposure to Australia generally will be higher than its exposure to New Zealand. The Fund invests in three &amp;#8220;sectors&amp;#8221;: government debt, semi-government debt and debt of supranational organizations. For purposes of this sector analysis, corporate issuers are included within the category of supranational organizations. The Fund&amp;#8217;s exposure to each sector is assessed relative to an equal-weighted baseline (e.g., 1/3 each). Sector exposures may be tilted within a narrow range around this baseline in order to take advantage of potential opportunities to enhance risk-adjusted return. The Fund&amp;#8217;s exposures to each country, sector and individual issuer are monitored from a risk perspective. The percentage of the Fund&amp;#8217;s assets invested in a specific country, sector or issuer may change, depending on market conditions, as agreed upon by the investment adviser and investment sub-adviser.  &lt;br/&gt;&lt;br/&gt;The universe of Debt Securities in which the Fund may invest includes securities that are rated &amp;#8220;investment grade&amp;#8221; as well as &amp;#8220;non-investment grade.&amp;#8221; Securities rated investment grade generally are considered to be of higher credit quality and subject to lower default risk. Although securities rated below investment grade may offer the potential for higher yields, they generally are subject to a higher potential risk of loss. &lt;br/&gt;&lt;br/&gt;The Fund attempts to limit interest rate risk by maintaining an aggregate portfolio duration of between two and eight years under normal market conditions. Aggregate portfolio duration is important to investors as an indication of the Fund&amp;#8217;s sensitivity to changes in interest rates. Funds with higher durations generally are subject to greater interest rate risk. For example, the value of a fund with a portfolio duration of ten years would be expected to drop by 10% for every 1% increase in interest rates. The Fund&amp;#8217;s actual portfolio duration may be longer or shorter depending upon market conditions. The Fund may also invest in short-term money market securities denominated in local currencies. &lt;br/&gt;&lt;br/&gt;The Fund may invest up to 20% of its net assets in derivatives such as forward currency contracts and swaps. The Fund&amp;#8217;s use of forward contracts and swaps will be underpinned by investments in cash or other liquid assets (typically, short-term, high-quality U.S. money market securities) and is designed to provide exposure similar to investments in locally denominated debt. A forward currency contract is an agreement to buy or sell a specific currency at a future date at a price set at the time of the contract. A swap is an agreement between two parties to exchange payments based on a reference asset, which may be a currency or interest rate but also may be a single asset, a pool of assets or an index of assets. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. A repurchase agreement is a transaction in which the Fund purchases securities or other obligations from a bank or securities dealer and simultaneously commits to resell them to a counterparty at an agreed-upon date or upon demand and at a price reflecting a market rate of interest unrelated to the coupon rate or maturity of the purchased obligations. Assets not invested in locally denominated debt generally will be invested in U.S. government securities and investment grade money market instruments. The Fund may invest up to 20% of its assets in debt instruments denominated in U.S. dollars issued by the Australian or New Zealand government, government agencies, corporations, regional development banks and supranational issuers. &lt;br/&gt;&lt;br/&gt;The decision to secure exposure through direct investment in bonds or indirectly through derivative transactions will be a function of, among other things, market accessibility, credit exposure, tax ramifications and regulatory requirements applicable to U.S. investment companies. If, subsequent to an investment, the 80% requirement is no longer met, the Fund&amp;#8217;s future investments will be made in a manner that will bring the Fund into compliance with this policy. The Trust will provide shareholders with sixty (60) days&amp;#8217; prior written notice of any change to this policy for the Fund.</rr:StrategyNarrativeTextBlock>

  <rr:RiskNarrativeTextBlock contextRef="Duration_02Jan2012_01Jan2013S000021343_Member">You can lose money on your investment in the Fund. The Fund is subject to the risks described below. Some or all of these risks may adversely affect the Fund&amp;#8217;s net asset value per share (&amp;#8220;NAV&amp;#8221;), trading price, yield, total return and/or ability to meet its objective. &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Investment Risk.&lt;/b&gt; As with all investments, an investment in the Fund is subject to investment risk. Investors in the Fund could lose money, including the possible loss of the entire principal amount of an investment, over short or long periods of time.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Market Risk.&lt;/b&gt; The trading prices of currencies, fixed income securities and other instruments fluctuate in response to a variety of factors. The Fund&amp;#8217;s NAV and market price may fluctuate significantly in response to these factors. As a result, an investor could lose money over short or long periods of time.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Shares of the Fund May Trade at Prices Other Than NAV.&lt;/b&gt; Although it is expected that the market price of the shares of the Fund will approximate the Fund&amp;#8217;s NAV when purchased and sold in the secondary market, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Cash Redemption Risk.&lt;/b&gt; The Fund&amp;#8217;s investment strategy will require it to effect redemptions, in whole or in part, for cash, triggering security sales. The sale of non-U.S. denominated securities can generate realized foreign exchange losses which could impact the income distributions paid by the Fund. Additionally, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used exclusively.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Counterparty and Issuer Credit Risk.&lt;/b&gt; The financial condition of an issuer of a debt security or other instrument or a counterparty to a derivative or other contract may cause such issuer or counterparty to default, become unable to pay interest or principal due or otherwise fail to honor its obligations. While the Fund attempts to limit credit and counterparty exposure in a manner consistent with its investment objective, the value of an investment in the Fund may change quickly and without warning in response to issuer or counterparty defaults and changes in the credit ratings of the Fund&amp;#8217;s portfolio investments.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Currency Exchange Rate Risk.&lt;/b&gt; The Fund invests a significant portion of its assets in investments denominated in Australian and New Zealand dollars, or in securities that provide exposure to Australian and New Zealand dollars, currency exchange rates or interest rates denominated in Australian and New Zealand dollars. Changes in currency exchange rates and the relative value of Australian and New Zealand dollars will affect the value of the Fund&amp;#8217;s investment and the value of your Fund shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt; Derivatives Investment Risk.&lt;/b&gt; The Fund may invest in derivatives. Derivatives are subject to a number of risks described elsewhere in this Prospectus, such as interest rate risk, market risk, and credit risk. They also involve the risk that changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, or that the counterparty to a derivative contract might default on its obligations. Derivatives can be volatile and may be less liquid than other securities. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Foreign Securities Risk.&lt;/b&gt; The Fund invests a significant portion of its assets in non-U.S. securities and instruments, or in securities that provide exposure to such securities and instruments. Investments in non-U.S. securities and instruments involve certain risks that may not be present with investments in U.S. securities, including the risk of loss due to foreign currency fluctuations or to political or economic instability.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Geographic Concentration in Australia and New Zealand.&lt;/b&gt; Because the Fund concentrates its investments in Australia and New Zealand, the Fund&amp;#8217;s performance is expected to be closely tied to social, political, and economic conditions within these countries and to be more volatile than the performance of more geographically diversified funds. The economies of Australia and New Zealand are both heavily dependent on the demand for commodity exports, including agricultural products. As a result, both economies are particularly vulnerable to international commodity prices and global economic slowdowns. These and other factors could have a negative impact on the Fund&amp;#8217;s performance and increase the volatility of an investment in the Fund.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;High Yield Securities Risk.&lt;/b&gt; Higher yielding, high risk debt securities, sometimes referred to as junk bonds, may present additional risk because these securities may be less liquid and present more credit risk than investment grade bonds. The price of high yield securities tends to be more susceptible to issuer-specific operating results and outlook and to real or perceived adverse economic and competitive industry conditions.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Interest Rate Risk.&lt;/b&gt; Interest rate risk is the risk that fixed income securities will decline in value because of changes in interest rates and other factors, such as perception of an issuer&amp;#8217;s creditworthiness.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Issuer-Specific Risk.&lt;/b&gt; Issuer-specific events, including changes in the financial condition of an issuer, can have a negative impact on the value of the Fund.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Management Risk.&lt;/b&gt; The Fund is actively managed using proprietary investment strategies and processes. There can be no guarantee that these strategies and processes will be successful or that the Fund will achieve its investment objective.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Non-Diversification Risk.&lt;/b&gt; The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. To the extent the Fund invests a significant percentage of its assets in a limited number of issuers, the Fund is subject to the risks of investing in those few issuers, and may be more susceptible to a single adverse economic or regulatory occurrence. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Repurchase Agreement Risk.&lt;/b&gt; The Fund&amp;#8217;s investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term.&lt;/li&gt;&lt;/ul&gt;</rr:RiskNarrativeTextBlock>

  <rr:StrategyNarrativeTextBlock contextRef="Duration_02Jan2012_01Jan2013S000021341_Member">The Fund is an actively managed exchange traded fund (&amp;#8220;ETF&amp;#8221;) that seeks to achieve its investment objective by investing in short-term securities designed to provide exposure to Indian currency and money market rates. Because the market for money market securities in India generally is less liquid and accessible to foreign investors than corresponding markets in other countries, the Fund intends to achieve exposure to currency markets in India by investing primarily in short-term U.S. money market securities and forward currency contracts and swaps. The combination of U.S. money market securities with forward currency contracts and currency swaps is designed to provide exposure equivalent to money market securities denominated in Indian rupees. A forward currency contract is an agreement to buy or sell a specific currency at a future date at a price set at the time of the contract. A currency swap is an agreement between two parties to exchange one currency for another at a future rate. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. A repurchase agreement is a transaction in which the Fund purchases securities or other obligations from a bank or securities dealer and simultaneously commits to resell them to a counterparty at an agreed-upon date or upon demand and at a price reflecting a market rate of interest unrelated to the coupon rate or maturity of the purchased obligations. &lt;br /&gt;&lt;br /&gt;In order to attempt to reduce interest rate risk, the Fund generally will maintain a weighted average portfolio maturity of 90 days or less with respect to the money market securities in its portfolio. The Fund will not purchase any security with a remaining maturity of more than 397 calendar days. All U.S. money market securities acquired by the Fund will be rated in the upper two short-term ratings by at least two nationally recognized statistical rating organizations (&amp;#8220;NRSROs&amp;#8221;) or, if unrated, deemed to be of equivalent quality. The Fund does not seek to preserve capital in U.S. dollars. &lt;br/&gt;&lt;br/&gt; The decision to secure exposure directly or indirectly will be a function of, among other things, market accessibility, credit exposure, and tax ramifications for foreign investors. If the Fund pursues direct investment, eligible investments include short-term securities issued by the government of India and its agencies or instrumentalities, bank debt obligations and time deposits, bankers&amp;#8217; acceptances, commercial paper, short-term corporate debt obligations, mortgage-backed securities and asset-backed securities.  &lt;br /&gt;&lt;br /&gt;The Fund will invest, under normal circumstances, at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in investments whose combined performance is tied economically to India. If, subsequent to an investment, the 80% requirement is no longer met, the Fund&amp;#8217;s future investments will be made in a manner that will bring the Fund into compliance with this policy. The Trust will provide shareholders with sixty (60) days&amp;#8217; prior notice of any change to this policy for the Fund.</rr:StrategyNarrativeTextBlock>

While the Fund attempts to limit credit and counterparty exposure in a manner consistent with its investment objective, the value of an investment in the Fund may change quickly and without warning in response to issuer or counterparty defaults and changes in the credit ratings of the Fund&amp;#8217;s portfolio investments.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Currency Exchange Rate Risk.&lt;/b&gt; The Fund invests a significant portion of its assets in investments denominated in Indian rupees, or in securities that provide exposure to Indian rupees, currency exchange rates or interest rates denominated in Indian rupees. Changes in currency exchange rates and the relative value of the Indian rupee will affect the value of the Fund&amp;#8217;s investment and the value of your Fund shares.

Such conditions may impact the ability of the Fund to buy, sell or otherwise transfer securities, adversely affect the trading market and price for Fund shares, and cause the Fund to decline in value.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Foreign Securities Risk.&lt;/b&gt; The Fund invests a significant portion of its assets in non-U.S. securities and instruments, or in securities that provide exposure to such instruments. Investments in non-U.S. securities and instruments involve certain risks that may not be present with investments in U.S. securities, including the risk of loss due to foreign currency fluctuations or to political or economic instability.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Geographic Concentration in India.&lt;/b&gt; Because the Fund concentrates its investments in India, the Fund&amp;#8217;s performance is expected to be closely tied to social, political, and economic conditions within India and to be more volatile than the performance of more geographically diversified funds. The Indian government has exercised and continues to exercise significant influence over many aspects of the economy. While the government of India is moving to a more liberal approach, it still places restrictions on the capability and capacity of foreign investors to access and trade rupee directly. While the Indian economy generally has experienced growth in recent years, there is no guarantee that this growth will continue. These and other factors could have a negative impact on the Fund&amp;#8217;s performance and increase the volatility of an investment in the Fund.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Interest Rate Risk.&lt;/b&gt; Interest rate risk is the risk that fixed income securities will decline in value because of changes in interest rates and other factors, such as perception of an issuer&amp;#8217;s creditworthiness.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Issuer-Specific Risk.&lt;/b&gt; Issuer-specific events, including changes in the financial condition of an issuer, can have a negative impact on the value of the Fund.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Management Risk.&lt;/b&gt; The Fund is actively managed using proprietary investment strategies and processes.

To the extent the Fund invests a significant percentage of its assets in a limited number of issuers, the Fund is subject to the risks of investing in those few issuers, and may be more susceptible to a single adverse economic or regulatory occurrence. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Offshore Investor Risk.&lt;/b&gt; In addition to the general risks associated with investing in non-U.S. currencies and non-U.S. currency markets, there are special risks associated with investing in Indian rupee or securities designed to provide exposure to Indian rupee. While the government of India is moving toward a more liberal approach, it still places restrictions on the capability and capacity of foreign investors to access and trade rupee directly. Foreign investors in India still face burdensome taxes on investments in income-producing securities. These limitations and restrictions may impact the availability, liquidity and pricing of securities designed to provide offshore investors with exposure to Indian markets. As a result, returns achieved by offshore investors, such as the Fund, could differ from those available to domestic investors in India.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Repurchase Agreement Risk.&lt;/b&gt; The Fund&amp;#8217;s investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements.

  <rr:StrategyNarrativeTextBlock contextRef="Duration_02Jan2012_01Jan2013S000028984_Member">The Fund seeks to achieve its investment objective through investment in Local Debt denominated in the local currencies of emerging market countries. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in Local Debt. For these purposes, Local Debt includes fixed income securities, such as bonds, notes or other debt obligations denominated in local currencies of emerging market countries, as well as certain derivatives and other instruments described herein. The Fund is an actively managed exchange traded fund (&amp;#8220;ETF&amp;#8221;).&lt;br/&gt;&lt;br/&gt;The Fund is designed to provide exposure to Local Debt of issuers from a broad range of emerging market regions and countries. The Fund intends to focus its investment on fixed income securities issued by emerging market governments, government agencies, and corporations. The Fund also may invest in fixed income securities denominated in an emerging market currency and issued by supranational organizations, such as the European Investment Bank, International Bank for Reconstruction and Development, International Finance Corporation, or other regional development banks. The Fund also may invest in debt securities linked to inflation rates outside the U.S., including securities or instruments linked to rates in emerging market countries.&lt;br/&gt;&lt;br/&gt;The Fund intends to provide exposure across several geographic regions and countries. The Fund intends to invest in Local Debt from the following regions: Asia, Latin America, Europe, the Middle East, and Africa. Within these regions, the Fund is likely to invest in countries such as: Brazil, Chile, China, Colombia, Czech Republic, Hungary, India, Indonesia, Malaysia, Mexico, Nigeria, Peru, the Philippines, Poland, Russia, South Africa, South Korea, Taiwan, Thailand and Turkey. This list  may change based on market developments. The Fund uses a structured investment approach that analyzes multiple factors. Countries are grouped into differentiated tiers based on an analysis of these factors. Subject to the Fund&amp;#8217;s general investment requirement to provide broad regional and country exposure, the Fund generally invests a higher percentage of its assets in countries that have larger and more liquid debt markets and that the Fund&amp;#8217;s adviser believes are pursuing sustainable fiscal and monetary policies in light of economic and market conditions. The country exposures are consistently monitored from a risk perspective and may be modified, reduced or eliminated. The Fund&amp;#8217;s exposure to any single country generally will be limited to 20% of the Fund&amp;#8217;s assets. The percentage of Fund assets invested in a specific region, country or issuer will change from time to time.&lt;br/&gt;&lt;br/&gt;The universe of emerging markets local currency debt currently includes securities that are rated &amp;#8220;investment grade&amp;#8221; as well as &amp;#8220;non-investment grade.&amp;#8221; The Fund intends to provide a broad-based exposure to emerging market debt and therefore will invest in both investment grade and non-investment grade securities. Securities rated investment grade generally are considered to be of higher credit quality and subject to lower default risk. Although securities rated below investment grade may offer the potential for higher yields, they generally are subject to a higher potential risk of loss.&lt;br/&gt;&lt;br/&gt;The Fund attempts to limit interest rate risk by maintaining an aggregate portfolio duration of between two and ten years under normal market conditions. Aggregate portfolio duration is important to investors as an indication of the Fund&amp;#8217;s sensitivity to changes in interest rates. Funds with higher durations generally are subject to greater interest rate risk. For example, the value of a fund with a portfolio duration of ten years would be expected to drop by 10% for every 1% increase in interest rates. The Fund&amp;#8217;s actual portfolio duration may be longer or shorter depending upon market conditions. The Fund may also invest in short-term money market securities denominated in the currencies of countries in which the Fund invests.&lt;br/&gt;&lt;br/&gt;The Fund may invest up to 30% of its net assets in derivatives such as forward currency contracts and swaps. The Fund&amp;#8217;s use of forward contracts and swaps will be underpinned by investments in cash or other liquid assets (typically short-term, high-quality U.S. money market securities) and is designed to provide exposure similar to investments in local currency debt. A forward currency contract is an agreement to buy or sell a specific currency at a future date at a price set at the time of the contract. A swap is an agreement between two parties to exchange payments based on a reference asset, which may be a currency or interest rate but also may be a single asset, a pool of assets or an index of assets. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. A repurchase agreement is a transaction in which the Fund purchases securities or other obligations from a bank or securities dealer and simultaneously commits to resell them to a counterparty at an agreed-upon date or upon demand and at a price reflecting a market rate of interest unrelated to the coupon rate or maturity of the purchased obligations. Local Debt also includes fixed income securities denominated in an emerging market currency and issued by a supranational organization or regional development bank. Assets not invested in Local Debt generally will be invested in U.S. government securities and investment grade money market instruments. The Fund may invest up to 20% of its assets in debt instruments denominated in U.S. dollars issued by emerging market governments, government agencies, corporations, regional development banks and supranational issuers, as well as derivatives based on such instruments.&lt;br/&gt;&lt;br/&gt;The decision to secure exposure through direct investment in bonds or indirectly through derivative transactions will be a function of, among other things, market accessibility, credit exposure, tax ramifications and regulatory requirements applicable to U.S. investment companies. If, subsequent to an investment, the 80% requirement is no longer met, the Fund&amp;#8217;s future investments will be made in a manner that will bring the Fund into compliance with this policy. The Trust will provide shareholders with sixty (60) days&amp;#8217; prior notice of any change to this policy for the Fund.</rr:StrategyNarrativeTextBlock>

The price of high yield securities tends to be more susceptible to issuer-specific operating results and outlook and to real or perceived adverse economic and competitive industry conditions.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Interest Rate Risk.&lt;/b&gt; Interest rate risk is the risk that fixed income securities will decline in value because of changes in interest rates and other factors, such as perception of an issuer&amp;#8217;s creditworthiness.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Issuer-Specific Risk.&lt;/b&gt; Issuer-specific events, including changes in the financial condition of an issuer, can have a negative impact on the value of the Fund.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Management Risk.&lt;/b&gt; The Fund is actively managed using proprietary investment strategies and processes. There can be no guarantee that these strategies and processes will be successful or that the Fund will achieve its investment objective.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Non-Diversification Risk.&lt;/b&gt; The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. To the extent the Fund invests a significant percentage of its assets in a limited number of issuers, the Fund is subject to the risks of investing in those few issuers, and may be more susceptible to a single adverse economic or regulatory occurrence. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Repurchase Agreement Risk.&lt;/b&gt; The Fund&amp;#8217;s investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Sovereign Debt Risk. &lt;/b&gt;Bonds issued by governments, sometimes referred to as &amp;#8220;sovereign&amp;#8221; debt, present risks not associated with investments in other types of bonds. The government or agency issuing the debt may be unable or unwilling to make interest payments and/or repay the principal owed. In such instance, the Fund may have limited recourse against the issuing government or agency. In the past, governments of emerging market countries have refused to honor their payment obligations on issued bonds.&lt;/li&gt;&lt;/ul&gt;</rr:RiskNarrativeTextBlock>

  <rr:StrategyNarrativeTextBlock contextRef="Duration_02Jan2012_01Jan2013S000033843_Member">The Fund seeks to achieve its investment objective through investment in debt securities issued by corporate entities that are domiciled in, or economically tied to, emerging market countries. The issuers of such debt will include public, private, and state-owned or sponsored corporations. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in Corporate Debt. For these purposes, Corporate Debt includes fixed income securities, such as bonds, notes, money market securities and other debt obligations (such as loan participation notes) of emerging market issuers. Corporate Debt does not include derivatives. The Fund is an actively managed exchange traded fund (&amp;#8220;ETF&amp;#8221;). &lt;br /&gt;&lt;br /&gt;The Fund intends to focus its investment on Corporate Debt issued in U.S. dollars. The Fund also may invest in Corporate Debt denominated in the local currency of emerging market countries. Non-U.S. dollar denominated debt is sometimes referred to as &amp;#8220;local debt.&amp;#8221; Local debt provides exposure to changes in the value of such non-U.S. currencies against the U.S. dollar. Corporate Debt includes debt securities issued by supranational organizations, such as the European Investment Bank, International Bank for Reconstruction and Development or International Finance Corporation, or other regional development banks. The Fund may invest to a limited extent in debt securities of emerging market governments (also known as &amp;#8220;sovereign debt&amp;#8221;) and debt securities linked to inflation rates in emerging market countries. &lt;br /&gt;&lt;br /&gt;The Fund intends to seek exposure to Corporate Debt from the following regions: Asia, Latin America, Eastern Europe, Africa and the Middle East. Within these regions, the Fund is likely to invest in countries such as: Argentina, Bahrain,  Barbados, Brazil, Chile, China, Colombia, Croatia, Czech Republic, Dominican Republic, Egypt, El Salvador, Hong Kong, Hungary, India, Indonesia, Israel, Jamaica, Kazakhstan, Kuwait, Macau, Malaysia, Mexico, Mongolia, Nigeria, Oman, Peru, the Philippines, Poland, Qatar, Russia, Saudi Arabia, Singapore, South Africa, South Korea, Taiwan, Thailand, Turkey, Ukraine, the United Arab Emirates, and Venezuela. This list may change based on market developments. The Fund employs a structured investment approach that utilizes &amp;#8220;top down&amp;#8221; analysis of macroeconomic factors and &amp;#8220;bottom up&amp;#8221; analysis of emerging market countries and issuers. The Fund&amp;#8217;s credit exposures are consistently monitored from a risk perspective and may be modified, reduced or eliminated. The Fund&amp;#8217;s exposure to any single issuer generally will be limited to 10% of the Fund&amp;#8217;s net assets. The Fund&amp;#8217;s exposure to any single country generally will be limited to 30% of the Fund&amp;#8217;s net assets. The percentage of Fund assets invested in a specific region, country or issuer will change from time to time.&lt;br/&gt;&lt;br/&gt;  The universe of emerging market Corporate Debt currently includes securities that are rated &amp;#8220;investment grade&amp;#8221; as well as &amp;#8220;non-investment grade&amp;#8221; (commonly referred to as &amp;#8220;junk bonds&amp;#8221;). The Fund intends to provide a broad exposure to emerging market Corporate Debt and therefore will invest in both investment grade and non-investment grade securities. Securities rated investment grade generally are considered to be of higher credit quality and subject to lower default risk. Although securities rated below investment grade may offer the potential for higher yields, they generally are subject to a higher potential risk of loss.  &lt;br /&gt;&lt;br /&gt;The Fund attempts to limit interest rate risk by maintaining an aggregate portfolio duration of between two and ten years under normal market conditions. Aggregate portfolio duration is important to investors as an indication of the Fund&amp;#8217;s sensitivity to changes in interest rates. Funds with higher durations generally are subject to greater interest rate risk. For example, the value of a fund with a portfolio duration of ten years would be expected to drop by 10% for every 1% increase in interest rates. The Fund&amp;#8217;s actual portfolio duration may be longer or shorter depending upon market conditions. The Fund may also invest in short-term money market securities denominated in U.S. dollars or the currencies of countries in which the Fund invests. &lt;br /&gt;&lt;br /&gt;The Fund may invest up to 20% of its net assets in derivatives, such as swaps and forward currency contracts. A swap is an agreement between two parties to exchange payments based on a reference asset, which may be a currency or interest rate but also may be a single asset, a pool of assets or an index of assets. A forward currency contract is an agreement to buy or sell a specific currency at a future date at a price set at the time of the contract. The Fund&amp;#8217;s use of derivatives will be underpinned by investments in cash or other liquid assets (typically short-term, high-quality money market securities). The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. A repurchase agreement is a transaction in which the Fund purchases securities or other obligations from a bank or securities dealer and simultaneously agrees to resell them to a counterparty at an agreed-upon date or upon demand and at a price reflecting a market rate of interest unrelated to the coupon rate or maturity of the purchased obligations. &lt;br /&gt;&lt;br /&gt;The Fund must invest at least 80% of its net assets directly in Corporate Debt. The decision to secure exposure through direct investment in Corporate Debt or indirectly through derivative transactions will be a function of, among other things, market accessibility, credit exposure, tax ramifications and regulatory requirements applicable to U.S. investment companies. If, subsequent to an investment, the Fund&amp;#8217;s 80% requirement is no longer met, the Fund&amp;#8217;s future investments will be made in a manner that will bring the Fund into compliance with this policy. The Trust will provide shareholders with sixty (60) days&amp;#8217; prior notice of any change to this policy for the Fund.</rr:StrategyNarrativeTextBlock>

It illustrates the hypothetical expenses that such investors would incur over various periods if they 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.

  <rr:StrategyNarrativeTextBlock contextRef="Duration_02Jan2012_01Jan2013S000026387_Member">The Fund is an actively managed exchange traded fund (&amp;#8220;ETF&amp;#8221;) that seeks to achieve positive total returns in rising or falling markets that are not directly correlated to broad market equity or fixed income returns. The Fund is managed using a quantitative, rules-based strategy designed to provide returns that correspond to the performance of the Diversified Trends Indicator&lt;sup style="POSITION: relative; BOTTOM: 0.8ex; VERTICAL-ALIGN: baseline"&gt;TM&lt;/sup&gt; (the &amp;#8220;Benchmark&amp;#8221;). The Benchmark is a widely used indicator designed to capture the economic benefit derived from rising or declining price trends in the markets for commodity, currency and U.S. Treasury futures.&lt;br/&gt;&lt;br/&gt;The Benchmark and Fund consist of ten commodity sectors (Energy, Grains, Precious Metals, Industrial Metals, Livestock, Natural Gas, Coffee, Cocoa, Cotton, and Sugar) and eight financial sectors (the Australian dollar, British pound, Canadian dollar, euro, Japanese yen, Swiss franc, U.S. Treasury notes and U.S. Treasury bonds) (each, a &amp;#8220;Sector&amp;#8221;). When the Energy Sector is &amp;#8220;long&amp;#8221; (as described below), the Fund&amp;#8217;s exposure will be weighted evenly between commodities and financials (approximately 50% each). When the Energy Sector is &amp;#8220;flat&amp;#8221; (as described below), the Fund&amp;#8217;s exposure will be weighted approximately 60% to financials and approximately 40% to commodities. Subject to the above limitations, a &amp;#8220;Base Weight&amp;#8221; for each Sector is set depending on whether the Energy Sector is long or flat. Commodity sectors that have higher historical production levels, and financial sectors from countries with higher Gross Domestic Product (&amp;#8220;GDP&amp;#8221;), have a higher Base Weight in the Benchmark and Fund. The weight of each Sector fluctuates intra-month based on the return of each Sector, but each Sector is reset back to its Base Weight at the end of each month and year.&lt;br/&gt;&lt;br/&gt;The Fund invests substantially all of its assets in a combination of commodity and currency-linked investments, U.S. government securities and money market instruments whose collective performance is designed to correspond to the performance of the Benchmark. The Fund&amp;#8217;s commodity- and currency-linked investments generally are limited to investments in listed futures contracts, forward currency contracts and swap transactions that provide exposure to commodity and non-U.S. currency returns. The Fund will invest in listed U.S. Treasury futures and also may invest directly in U.S. Treasury notes and bonds. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. A repurchase agreement is a transaction in which the Fund purchases securities or other obligations from a bank or securities dealer and simultaneously commits to resell them to a counterparty at an agreed-upon date or upon demand and at a price reflecting a market rate of interest unrelated to the coupon rate or maturity of the purchased obligations. The Fund also may invest in structured notes based on commodities. The Fund does not invest directly in physical commodities.&lt;br/&gt;&lt;br/&gt;The Fund attempts to capture the economic benefit derived from rising and declining trends based on the &amp;#8220;moving average&amp;#8221; price changes of commodity, currency and U.S. Treasury futures. In an attempt to capture these trends, the Fund&amp;#8217;s investments are positioned as either &amp;#8220;long&amp;#8221; or &amp;#8220;short&amp;#8221; (with the exception of the Energy Sector). To be &amp;#8220;long&amp;#8221; means to hold or be exposed to a security or instrument with the expectation that its value will increase over time. To be &amp;#8220;short&amp;#8221; means to sell or be exposed to a security or instrument with the expectation that it will fall in value. On a monthly basis, each Sector&amp;#8217;s returns are compared to its recent weighted moving average monthly returns. If the monthly return is higher than the moving average returns, the Sector is positioned as &amp;#8220;long&amp;#8221; throughout the following month. If the Sector&amp;#8217;s returns are below its moving average returns, the Sector is positioned as &amp;#8220;short&amp;#8221; (with the exception of the Energy Sector, which would be &amp;#8220;flat&amp;#8221;). The Fund will benefit if it has a long position in a security or instrument that increases in value or a short position in a security or instrument that decreases in value. Conversely, the Fund will be adversely impacted if it holds a long position in a security or instrument that declines in value and a short position in a security or instrument that increases in value. The Energy Sector is positioned as either long or flat; it is never short. When the Energy Sector is flat, the Fund will not have any exposure to the Energy Sector and it will allocate a higher percentage of its investments to other Sectors within the Benchmark. The Fund generally does not make intra-month adjustments to its portfolio or the direction of its long and short positions. Although the Fund seeks returns comparable to the returns of the Benchmark, the Fund may have a higher or lower exposure to any Sector or component within the Benchmark at any time. The Fund will not hold more than 25% of its assets in any one industry. For these purposes, the components of the Benchmark (e.g., gold, crude oil) will be considered a separate industry. Neither the Fund nor the Benchmark is leveraged.&lt;br/&gt;&lt;br/&gt;The Fund seeks to gain exposure to commodity markets, in whole or in part, through investments in a subsidiary organized in the Cayman Islands (the &amp;#8220;WisdomTree Subsidiary&amp;#8221;). The WisdomTree Subsidiary is wholly-owned and controlled by the Fund. The Fund&amp;#8217;s investment in the WisdomTree Subsidiary may not exceed 25% of the Fund&amp;#8217;s total assets at each quarter-end of the Fund&amp;#8217;s fiscal year. The Fund&amp;#8217;s investment in the WisdomTree Subsidiary is intended to provide the Fund with exposure to commodity returns within the limits of the federal tax requirements applicable to regulated investment companies, such as the Fund. Except as noted, references to the investment strategies and risks of the Fund include the investment strategies and risks of the WisdomTree Subsidiary.&lt;br/&gt;&lt;br/&gt;The Fund will invest, under normal circumstances, at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in &amp;#8220;managed futures.&amp;#8221; For these purposes, managed futures are investments in commodity and currency -linked instruments, as well as U.S. government securities and money market instruments, that taken together have economic characteristics similar or equivalent to those of the listed commodity, currency and financial futures contracts described herein. If, subsequent to an investment, the 80% requirement is no longer met, the Fund&amp;#8217;s future investments will be made in a manner that will bring the Fund into compliance with this policy. The Trust will provide shareholders with sixty (60) days&amp;#8217; prior notice of any change to this policy for the Fund.</rr:StrategyNarrativeTextBlock>

Some or all of these risks may adversely affect the Fund&amp;#8217;s net asset value per share (&amp;#8220;NAV&amp;#8221;), trading price, yield, total return and/or its ability to meet its objective.&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Investment Risk.&lt;/b&gt; As with all investments, an investment in the Fund is subject to investment risk.

The Fund&amp;#8217;s NAV and market price may fluctuate significantly in response to these factors. As a result, an investor could lose money over short or long periods of time.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Shares of the Fund May Trade at Prices Other Than NAV.&lt;/b&gt; Although it is expected that the market price of the shares of the Fund will approximate the Fund&amp;#8217;s NAV when purchased and sold in the secondary market, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Benchmark Risk.&lt;/b&gt; The Benchmark is entirely model-based. As market dynamics shift over time, the model may become outdated or inaccurate. The Benchmark and the Fund will take both long and short positions and should not be used as proxies for taking long-only positions. The Benchmark and Fund could lose significant value during periods when long-only indexes rise. Similarly, the Benchmark and Fund are not a substitute for short-only positions. The Benchmark does not make intra-month adjustments. As a result, the Fund generally will not make intra-month adjustments to the positions it established at the end of the prior month. As a result, the Benchmark and Fund are subject to substantial losses if the market moves against the established positions on an intra-month basis. The Benchmark is based on historical price trends. There can be no assurance that such trends will be reflected in future market movements. In markets without sustained price trends, or markets with significant price movements that quickly reverse, the Benchmark and the Fund may suffer significant losses. The Benchmark is based on the price of futures contracts. Futures contracts reflect the expected future value of a commodity, currency or Treasury security. The Benchmark and Fund do not reflect &amp;#8220;spot&amp;#8221; prices. Spot prices reflect immediate delivery value, not expected future value.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Cash Redemption Risk.&lt;/b&gt; The Fund&amp;#8217;s investment strategy will require it to effect redemptions, in whole or in part, for cash. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used exclusively. Additionally, the realization of foreign exchange losses through security sales can impact income distributions paid by the Fund.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Commodity Risk.&lt;/b&gt; The value of commodities and commodity-linked derivative instruments typically is based upon the price movements of a physical commodity or an economic variable linked to such price movements. The prices of commodities and commodity-related investments may fluctuate quickly and dramatically and may not correlate to price movements in other asset classes. An active trading market may not exist for certain commodities. Each of these factors and events could have a significant negative impact on the Fund.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Counterparty Risk.&lt;/b&gt; The Fund bears the risk that the counterparty to a derivative or other contract with a third party may default on its obligations or otherwise fail to honor its obligations. If a counterparty defaults on its payment obligations the Fund will lose money and the value of an investment in Fund shares may decrease. In addition, the Fund may engage in such investment transactions with a limited number of counterparties.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Credit Risk.&lt;/b&gt; The financial condition of an issuer of a debt security or other instrument may cause it to default or become unable to pay interest or principal due or otherwise fail to perform. The Fund cannot collect interest and principal payments on a security or instrument if the issuer defaults. While the Fund attempts to limit credit exposure in a manner consistent with its investment objective, the value of an investment in the Fund may change quickly and without warning in response to issuer defaults and changes in the credit ratings of the Fund&amp;#8217;s portfolio investments.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Currency Exchange Rate Risk.&lt;/b&gt; The Fund currently invests a relatively large percentage of its assets in investments denominated in non-U.S. currencies, or in securities that provide exposure to such currencies, currency exchange rates or interest rates denominated in such currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund&amp;#8217;s investment and the value of your Fund shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Derivatives Investment Risk.&lt;/b&gt; The Fund may invest in derivatives. Derivatives are subject to a number of risks described elsewhere in this Prospectus, such as interest rate risk, market risk, and credit risk. They also involve the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index, or that the counterparty to a derivative contract might default on its obligations. Derivatives can be volatile and may be less liquid than other securities. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Interest Rate Risk.&lt;/b&gt; Interest rate risk is the risk that fixed income securities will decline in value because of changes in interest rates and other factors, such as perception of an issuer&amp;#8217;s creditworthiness.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Issuer-Specific Risk.&lt;/b&gt; Issuer-specific events, including changes in the financial condition of an issuer, can have a negative impact on the value of the Fund.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Liquidity Risk.&lt;/b&gt; The Fund may invest in derivatives and other instruments that may be less liquid than other types of investments. The derivatives in which the Fund invests may not always be liquid. This could have a negative effect on the Fund&amp;#8217;s ability to achieve its investment objective and may result in losses to Fund shareholders.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Management Risk.&lt;/b&gt; The Fund is actively managed using proprietary investment strategies and processes. There can be no guarantee that these strategies and processes will be successful or that the Fund will achieve its investment objective.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Non-Diversification Risk.&lt;/b&gt; The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. To the extent the Fund invests a significant percentage of its assets in a limited number of issuers, the Fund is subject to the risks of investing in those few issuers, and may be more susceptible to a single adverse economic or regulatory occurrence. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Portfolio Turnover Risk.&lt;/b&gt; The Fund&amp;#8217;s strategy may frequently involve buying and selling portfolio securities to rebalance the Fund&amp;#8217;s exposure to various market sectors. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs and generating greater tax liabilities for shareholders. Portfolio turnover risk may cause the Fund&amp;#8217;s performance to be less than you expect.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Repurchase Agreement Risk.&lt;/b&gt; The Fund&amp;#8217;s investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Short Sales Risk.&lt;/b&gt; The Fund may engage in &amp;#8220;short sale&amp;#8221; transactions. The Fund will lose value if the security or instrument that is the subject of a short sale increases in value. The Fund also may enter into a short derivative position through a futures contract, swap agreement, structured note, or short positions on currency forwards. If the price of the security or derivative that is the subject of a short sale increases, then the Fund will incur a loss equal to the increase in price from the time that the short sale was entered into plus any premiums and interest paid to a third party in connection with the short sale. Therefore, short sales involve the risk that losses may be exaggerated, potentially losing more money than the actual cost of the investment. Also, there is the risk that the third party to the short sale may fail to honor its contract terms, causing a loss to the Fund.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Subsidiary Investment Risk.&lt;/b&gt; Changes in the laws of the United States and/or the Cayman Islands, under which the Fund and the WisdomTree Subsidiary are organized, respectively, could result in the inability of the WisdomTree Subsidiary to operate as intended and could negatively affect the Fund and its shareholders.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Tax Risk.&lt;/b&gt; The Fund expects to obtain exposure to the commodities markets by entering into commodity-linked derivative instruments, such as listed futures contracts. In order for the Fund to qualify as a regulated investment company, the Fund must derive at least 90% of its gross income each taxable year from qualifying income. Income from certain commodity-linked derivative instruments in which the Fund invests may not be considered qualifying income. The Fund will seek to limit such income so as to qualify as a regulated investment company. The Fund intends to invest in such commodity-linked derivative instruments indirectly through the WisdomTree Subsidiary. Failure to comply with the requirements for qualification as a regulated investment company would have significant negative tax consequences to Fund shareholders.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Volatility Risk.&lt;/b&gt; The Fund and its underlying Benchmark are designed to capture the long-term economic benefits of rising or declining market trends. Frequent or significant short-term price movements could adversely impact the performance of the Benchmark and the Fund.&lt;/li&gt;&lt;/ul&gt;</rr:RiskNarrativeTextBlock>

  <rr:StrategyNarrativeTextBlock contextRef="Duration_02Jan2012_01Jan2013S000026386_Member">The Fund is an actively managed exchange traded fund (&amp;#8220;ETF&amp;#8221;) that seeks to provide protection against inflation and to generate income. &amp;#8220;Inflation&amp;#8221; is defined as an increase in the general price level of goods and services over time. The Fund invests in a combination of inflation-linked securities and debt instruments from issuers in the United States, developed markets and emerging markets throughout the world. The Fund has targeted exposure to commodities, such as gold, and employs commodity strategies structured to provide returns that exceed inflation rates. The Fund is managed using a structured investment approach that considers, among other things, country and currency exposure, sector allocation, investment exposure, and risk. &lt;br/&gt;&lt;br/&gt;Investments in Inflation-Linked Bonds and Other Instruments. As noted above, the Fund invests in fixed income securities and other instruments linked to inflation rates in the U.S. and in developed and emerging market countries throughout the world. The Fund&amp;#8217;s U.S. investments are focused on inflation-protected securities, such as U.S. Treasury Inflation Protected Securities (&amp;#8220;TIPS&amp;#8221;), and floating-rate securities. Outside the U.S., the Fund seeks broad-based exposure to both developed and emerging economies. The Fund focuses its investments outside the U.S. in countries that are leading exporters of commodities, such as Australia, Brazil, Canada, Chile, Mexico, and South Africa. In order to provide broad-based exposure  across developed and emerging markets, the Fund also invests in issuers from countries such as France, Germany, Italy, Israel, Korea, Poland, Sweden, Turkey and the United Kingdom. This list may change from time to time based on market and other conditions. Country, sector and issuer exposure and risk are reviewed on an ongoing basis and the Fund&amp;#8217;s portfolio is rebalanced quarterly. The Fund&amp;#8217;s exposure to any single non-U.S. currency generally is limited to 10% of the Fund&amp;#8217;s assets.  &lt;br/&gt;&lt;br/&gt;The Fund intends to focus its investments in inflation-linked bonds and other debt instruments issued by governments, government agencies and instrumentalities, government-sponsored enterprises and supranational organizations. For these purposes, &amp;#8220;supranational organizations&amp;#8221; include entities such as the European Investment Bank, International Bank for Reconstruction and Development, International Finance Corporation, and other regional development banks. The Fund may also invest up to 20% in debt securities issued by corporations. Inflation-linked bonds are structured to provide protection against inflation by preserving purchasing power. In a typical inflation-linked bond, the principal amount of the bond and the cash flow generated by the bond (i.e., interest) are adjusted upward in response to increases in inflation rates. The U.S. Consumer Price Index, or CPI, is a commonly used measure of U.S. inflation rates. Bonds tied to inflation rates outside the U.S. generally are linked to regional or country measures comparable to the CPI that measure inflation rates in non-U.S. markets. As inflation rises, upward adjustments to the principal amount or income paid on the bond increase the value of the bond and help preserve purchasing power in response to inflation. Conversely, some types of inflation-linked bonds may be adjusted downward in response to deflation (i.e., a decrease in the prices of goods and services over time). &lt;br/&gt;&lt;br/&gt;The Fund may invest in floating- and variable-rate bonds. Floating- and variable-rate bonds are bonds that have a variable payment feature tied to a reference rate, such as the federal funds rate or the London Interbank Offering Rate (&amp;#8220;LIBOR&amp;#8221;). Floating- and variable-rate bonds generally are less sensitive to interest rate increases because when market rates rise, the payments made by such bonds increase. Conversely, a decrease in market interest rates will adversely affect the income received from such securities and may cause the value of such bonds to decrease. &lt;br/&gt;&lt;br/&gt;The Fund may invest in derivatives such as swaps, forward currency contracts, and futures contracts designed to provide protection from changes in inflation rates. A swap is an agreement between two parties to exchange payments based on a reference asset, which may be a currency or interest rate but also may be a single asset, a pool of assets or an index of assets. A forward currency contract is an agreement to buy or sell a specific currency at a future date at a price set at the time of the contract. A futures contract is a standardized contract traded on a recognized exchange in which two parties agree to exchange either a specified financial asset or the cash equivalent of said asset of standardized quantity and quality for a price agreed today (the futures prices or the strike price) with delivery occurring at a specified future date. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. A repurchase agreement is a transaction in which the Fund purchases securities or other obligations from a bank or securities dealer and simultaneously commits to resell them to a counterparty at an agreed-upon date or upon demand and at a price reflecting a market rate of interest unrelated to the coupon rate or maturity of the purchased obligations. &lt;br/&gt;&lt;br/&gt;The average duration of the fixed income portion of the Fund&amp;#8217;s portfolio will vary based on economic fundamentals and market conditions. During most scenarios, fixed income portfolio duration will not exceed 10 years. Duration is an important indication of the Fund&amp;#8217;s sensitivity to changes in interest rates. Funds with higher durations generally are subject to greater interest rate risk. For example, the value of a fund with a portfolio duration of ten years would be expected to drop by 10% for every 1% increase in interest rates. While the Fund intends to invest a relatively large percentage of its assets in &amp;#8220;investment grade&amp;#8221; securities, the Fund also may invest in &amp;#8220;non-investment grade&amp;#8221; securities. Securities rated investment grade generally are considered to be of higher credit quality and subject to lower default risk. Although securities rated below investment grade may offer the potential for higher yields, they generally are subject to higher potential risk of loss. &lt;br/&gt;&lt;br/&gt;While inflation-linked securities offer protection against inflation, they are sensitive to changes in &amp;#8220;real interest rates.&amp;#8221; Real interest rates are interest rates that have been adjusted to remove the cost of inflation. Protracted increases in real interest rates would likely have a negative impact on the value of inflation-linked securities and the value of the Fund. The Fund may purchase or sell futures contracts on U.S. Treasury securities or other U.S. government or non-U.S. government obligations to help minimize this risk. &lt;br/&gt;&lt;br/&gt;The Fund may invest a portion of its assets in fixed income securities that are not linked to inflation, such as U.S. government obligations. The Fund also may invest in money market instruments (including repurchase agreements) with remaining maturities of one year or less, as well as cash and cash equivalents. &lt;br/&gt;&lt;br/&gt;Investments in Commodities. The Fund intends to have targeted exposure to commodities and commodity strategies. The commodity exposure is diversified across a number of sectors (such as gold and other precious metals, industrial materials, energy, livestock, and agriculture) utilizing systematic, rules-based strategies. Within these strategies, the Fund may take or gain exposure to &amp;#8220;long&amp;#8221; or &amp;#8220;short&amp;#8221; positions in commodities and related instruments. To be &amp;#8220;long&amp;#8221; means to hold or be exposed to a commodity or instrument with the expectation that its value will increase over time. To be &amp;#8220;short&amp;#8221; means to sell or be exposed to a commodity or instrument with the expectation that it will fall in value. The Fund will benefit if it has a long  position in a commodity or instrument that increases in value or a short position in a commodity or instrument that decreases in value. Conversely, the Fund will be adversely impacted if it holds a long position in a commodity or instrument that declines in value and a short position in a commodity or instrument that increases in value. &lt;br/&gt;&lt;br/&gt;The Fund seeks to gain exposure to commodity markets, in whole or in part, through investments in a subsidiary organized in the Cayman Islands (the &amp;#8220;WisdomTree Subsidiary&amp;#8221;). The WisdomTree Subsidiary is wholly-owned and controlled by the Fund. The Fund&amp;#8217;s investment in the WisdomTree Subsidiary may not exceed 25% of the Fund&amp;#8217;s total assets at each quarter-end of the Fund&amp;#8217;s fiscal year. The Fund&amp;#8217;s investment in the WisdomTree Subsidiary is intended to provide the Fund with exposure to commodity returns within the limits of the federal tax requirements applicable to regulated investment companies, such as the Fund. The WisdomTree Subsidiary intends to achieve exposure to commodities through investment in a combination of listed commodity futures, commodity index swaps and structured notes that provide commodity returns. A listed commodity future is a financial instrument in which a party agrees to pay a fixed price for a designated commodity at a specified future date. Listed commodity futures are traded at market prices on exchanges pursuant to terms common to all market participants. Except as noted, references to the investment strategies and risks of the Fund include the investment strategies and risks of the WisdomTree Subsidiary.</rr:StrategyNarrativeTextBlock>

  <rr:StrategyNarrativeTextBlock contextRef="Duration_02Jan2012_01Jan2013S000021354_Member">The Fund seeks to achieve its investment objective through investment in Debt Securities denominated in euros. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in Debt Securities. For these purposes, Debt Securities consist of fixed income securities, such as bonds, notes or other debt obligations, denominated in euros, as well as certain derivatives and other instruments described herein. The Fund is an actively managed exchange traded fund ("ETF").&lt;br/&gt;&lt;br/&gt;The Fund intends to focus its investments on bonds and other debt instruments denominated in euros and issued by governments (national, state and local), government agencies and instrumentalities, government-sponsored enterprises and supranational organizations. For these purposes, "supranational organizations" include entities such as the European Investment Bank, International Bank for Reconstruction and Development, International Finance Corporation, or other regional development banks. The Fund also may invest in Debt Securities of corporate issuers organized in euro area countries or that have significant economic ties to euro area countries, although this is not expected to be a focus of the Fund.&lt;br/&gt;&lt;br/&gt;The Fund is designed to provide broad exposure to Debt Securities of issuers in euro area countries. The euro area is a group of 17 members of the European Union that have adopted the euro as their common currency. The euro area currently consists of Austria, Belgium, Cyprus, Estonia, Finland, France, Germany, Greece, Ireland, Italy, Luxembourg, Malta, the Netherlands, Portugal, Slovakia, Slovenia, and Spain. The Fund's exposure to the euro area countries is monitored from a risk perspective and may be modified, reduced or eliminated at any time. Initially, the Fund does not intend to invest in national, state or local debt of Ireland, Italy, Greece, Portugal, Spain, Estonia, Cyprus or Malta.&lt;br/&gt;&lt;br/&gt;The Fund will seek to concentrate its investments in Debt Securities of more credit worthy issuers within the region. This currently includes sizable positions in the sovereign debt of Germany and France with attempted balanced allocations to the sovereign debt of other euro area countries as well as supranational issuers. Subject to the Fund's general investment requirement to provide broad regional and country exposure, the Fund generally invests a higher percentage of its assets in countries that have larger and more liquid debt markets. The Fund's exposure to any single country generally will be limited to 20% of the Fund's assets. The euro area countries in which the Fund invests and the percentage of Fund assets invested in a particular euro area country or issuer will change from time to time, depending on market conditions, as agreed upon by the investment adviser and investment sub-adviser.&lt;br/&gt;&lt;br/&gt;The universe of Debt Securities in which the Fund may invest includes securities that are rated "investment grade" as well as "non-investment grade." The Fund, however, will focus its investments on investment grade securities. Securities rated investment grade generally are considered to be of higher credit quality and subject to lower default risk. Although securities rated below investment grade may offer the potential for higher yields, they generally are subject to a higher potential risk of loss.&lt;br/&gt;&lt;br/&gt;The Fund attempts to limit interest rate risk by maintaining an aggregate portfolio duration of between two and eight years under normal market conditions. Aggregate portfolio duration is important to investors as an indication of the Fund's sensitivity to changes in interest rates. Funds with higher durations generally are subject to greater interest rate risk. For example, the value of a fund with a portfolio duration of ten years would be expected to drop by 10% for every 1% increase in interest rates. The Fund's actual portfolio duration may be longer or shorter depending upon market conditions. The Fund may also invest in short-term money market securities denominated in euros.&lt;br/&gt;&lt;br/&gt;The Fund may invest up to 20% of its net assets in derivatives such as forward currency contracts and swaps. The Fund's use of forward contracts and swaps will be underpinned by investments in cash or other liquid assets (typically short-term, high-quality U.S. money market securities) and is designed to provide exposure similar to investments in euro-denominated debt. A forward currency contract is an agreement to buy or sell a specific currency at a future date at a price set at the time of the contract. A swap is an agreement between two parties to exchange payments based on a reference asset, which may be a currency or interest rate but also may be a single asset, a pool of assets or an index of assets. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. A repurchase agreement is a transaction in which the Fund purchases securities or other obligations from a bank or securities dealer and simultaneously commits to resell them to a counterparty at an agreed-upon date or upon demand and at a price reflecting a market rate of interest unrelated to the coupon rate or maturity of the purchased obligations. Assets not invested in euro-denominated debt generally will be invested in U.S. government securities and investment grademoney market instruments. The Fund may invest up to 20% of its assets in debt instruments denominated in U.S. dollars issued by EU governments, government agencies, corporations, regional development banks and supranational issuers.&lt;br/&gt;&lt;br/&gt;The decision to secure exposure through direct investment in bonds or indirectly through derivative transactions will be a function of, among other things, market accessibility, credit exposure, tax ramifications and regulatory requirements applicable to U.S. investment companies. If, subsequent to an investment, the 80% requirement is no longer met, the Fund's future investments will be made in a manner that will bring the Fund into compliance with this policy. The Trust will provide shareholders with sixty (60) days' prior written notice of any change to this policy for the Fund.</rr:StrategyNarrativeTextBlock>

While the Fund attempts to limit credit and counterparty exposure in a manner consistent with its investment objective, the value of an investment in the Fund may change quickly and without warning in response to issuer or counterparty defaults and changes in the credit ratings of the Fund&amp;#8217;s portfolio investments.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Currency Exchange Rate Risk.&lt;/b&gt; The Fund currently invests a relatively large percentage of its assets in investments denominated in non-U.S. currencies, or in securities that provide exposure to such currencies, currency exchange rates or interest rates denominated in such currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund&amp;#8217;s investment and the value of your Fund shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Deflation Risk.&lt;/b&gt; The Fund currently invests a relatively large percentage of its assets in inflation-linked securities and instruments that provide similar exposure. In the event of a general decline in commodity and consumer prices, commonly referred to as &amp;#8220;deflation,&amp;#8221; these securities may lose value and have an adverse effect on Fund performance.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Derivatives Investment Risk.&lt;/b&gt; The Fund may invest in derivatives. Derivatives are subject to a number of risks described elsewhere in this Prospectus, such as interest rate risk, market risk, and credit risk. They also involve the risk that changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, or that the counterparty to a derivative contract might default on its obligations. Derivatives can be volatile and may be less liquid than other securities. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Emerging Markets Risk.&lt;/b&gt; Investments in securities and instruments traded in developing or emerging markets, or that provide exposure to such securities or markets, can involve additional risks relating to political, economic, or regulatory conditions not associated with investments in U.S. securities and instruments or investments in more developed international markets. For example, developing or emerging market governments may, without prior warning, impose capital controls on the ability to transfer currency, securities or other assets. The Fund&amp;#8217;s ability to access certain developing or emerging markets also may be limited due to a variety of factors, including currency convertibility issues. Such conditions may impact the ability of the Fund to buy, sell or otherwise transfer securities or currency, cause the Fund&amp;#8217;s returns to differ from those available to domestic investors, adversely affect the trading market and price for Fund shares and cause the Fund to decline in value. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt; High Yield Securities Risk.&lt;/b&gt; Higher yielding, high risk debt securities, sometimes referred to as junk bonds, may present additional risk because these securities may be less liquid and present more credit risk than investment grade bonds. The price of high yield securities tends to be more susceptible to issuer-specific operating results and outlook and to real or perceived adverse economic and competitive industry conditions.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Income Fluctuation Risk.&lt;/b&gt; The Fund&amp;#8217;s periodic income distributions are likely to fluctuate considerably more than the income distributions of a typical bond fund. The Fund&amp;#8217;s income may decline during periods of deflation or due to changes in expectations concerning the rate of inflation. In deflationary environments, the principal and income of an inflation-protected security will decline and could result in losses for the Fund.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Inflation Risk.&lt;/b&gt; An increase in the principal amount of an inflation-linked bond will be considered taxable ordinary income, even though investors do not receive the increased principal until maturity. As a result, in certain circumstances, the Fund may be required to make annual distributions to shareholders that exceed the cash received by the Fund on its investments. This may cause the Fund to liquidate investments when it might not be advantageous to do so and may have negative tax consequences.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Interest Rate Risk.&lt;/b&gt; Interest rate risk is the risk that fixed income securities will decline in value because of changes in interest rates and other factors, such as perception of an issuer&amp;#8217;s creditworthiness.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Issuer-Specific Risk.&lt;/b&gt; Issuer-specific events, including changes in the financial condition of an issuer, can have a negative impact on the value of the Fund.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt; Liquidity Risk.&lt;/b&gt; The Fund may invest in derivatives and other instruments that may be less liquid than other types of investments. The derivatives in which the Fund invests may not always be liquid. This could have a negative effect on the Fund&amp;#8217;s ability to achieve its investment objective and may result in losses to Fund shareholders.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Management Risk.&lt;/b&gt; The Fund is actively managed using proprietary investment strategies and processes. There can be no guarantees that these strategies and processes will be successful or that the Fund will achieve its investment objective.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Non-Diversification Risk.&lt;/b&gt; The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. To the extent the Fund invests a significant percentage of its assets in a limited number of issuers, the Fund is subject to the risks of investing in those few issuers, and may be more susceptible to a single adverse economic or regulatory occurrence. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Non-U.S. Markets Risk.&lt;/b&gt; The Fund may invest in bonds and other instruments issued by non-U.S. governments or that track non-U.S. interest or inflation rates. Foreign markets are generally less liquid and can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, market, or economic developments and can perform differently from the U.S. market. Each of these factors may impact the ability of the Fund to buy, sell or otherwise transfer securities, adversely affect the trading market and price for Fund shares, and cause the Fund to decline in value.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Portfolio Turnover Risk.&lt;/b&gt; The Fund&amp;#8217;s strategy may frequently involve buying and selling portfolio securities to rebalance the Fund&amp;#8217;s exposure to various market sectors. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs and generating greater tax liabilities for shareholders. Portfolio turnover risk may cause the Fund&amp;#8217;s performance to be less than you expect.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Repurchase Agreement Risk.&lt;/b&gt; The Fund&amp;#8217;s investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Short Sales Risk.&lt;/b&gt; The Fund may engage in &amp;#8220;short sale&amp;#8221; transactions. The Fund will lose value if the security or instrument that is the subject of a short sale increases in value. The Fund also may enter into a short derivative position through a futures contract, swap agreement, structured note, or short positions on currency forwards. If the price of the security or derivative that is the subject of a short sale increases, then the Fund will incur a loss equal to the increase in price from the time that the short sale was entered into plus any premiums and interest paid to a third party in connection with the short sale. Therefore, short sales involve the risk that losses may be exaggerated, potentially losing more money than the actual cost of the investment. Also, there is the risk that the third party to the short sale may fail to honor its contract terms, causing a loss to the Fund.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Sovereign Debt Risk.&lt;/b&gt; Bonds issued by governments, sometimes referred to as &amp;#8220;sovereign&amp;#8221; debt, present risks not associated with investments in other types of bonds. The government or agency issuing the debt may be unable or unwilling to make interest payments and/or repay the principal owed. In such instance, the Fund may have limited recourse against the issuing government or agency. In the past, governments of emerging market countries have refused to honor their payment obligations on issued bonds.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Subsidiary Investment Risk.&lt;/b&gt; Changes in the laws of the United States and/or the Cayman Islands, under which the Fund and the WisdomTree Subsidiary are organized, respectively, could result in the inability of the WisdomTree Subsidiary to operate as intended and could negatively affect the Fund and its shareholders.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt;&lt;b&gt;Tax Risk.&lt;/b&gt; The Fund expects to obtain exposure to the commodities markets by entering into commodity-linked derivative instruments, such as listed futures contracts. In order for the Fund to qualify as a regulated investment company, the Fund must derive at least 90% of its gross income each taxable year from qualifying income. Income from certain commodity-linked derivative instruments in which the Fund invests may not be considered qualifying income. The Fund will seek to limit such income so as to qualify as a regulated investment company. The Fund intends to invest in such commodity-linked derivative instruments indirectly through the WisdomTree Subsidiary. Failure to comply with the requirements for qualification as a regulated investment company would have significant negative tax consequences to Fund shareholders.&lt;/li&gt;&lt;/ul&gt;</rr:RiskNarrativeTextBlock>

  <rr:RiskNarrativeTextBlock contextRef="Duration_02Jan2012_01Jan2013S000021354_Member">You can lose money on your investment in the Fund. The Fund is subject to the risks described below. Some or all of these risks may adversely affect the Fund&amp;#8217;s net asset value per share (&amp;#8220;NAV&amp;#8221;), trading price, yield, total return and/or ability to meet its objective. &lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt; &lt;b&gt;Investment Risk.&lt;/b&gt; As with all investments, an investment in the Fund is subject to investment risk. Investors in the Fund could lose money, including the possible loss of the entire principal amount of an investment, over short or long periods of time.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt; &lt;b&gt; Market Risk.&lt;/b&gt; The trading prices of currencies, fixed income securities and other instruments fluctuate in response to a variety of factors. The Fund&amp;#8217;s NAV and market price may fluctuate significantly in response to these factors. As a result, an investor could lose money over short or long periods of time.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt; &lt;b&gt;Shares of the Fund May Trade at Prices Other Than NAV.&lt;/b&gt; Although it is expected that the market price of the shares of the Fund will approximate the Fund&amp;#8217;s NAV when purchased and sold in the secondary market, there may be times when the market price of the shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt; &lt;b&gt;Cash Redemption Risk.&lt;/b&gt; The Fund&amp;#8217;s investment strategy will require it to effect redemptions, in whole or in part, for cash, triggering security sales. The sale of non-U.S. denominated securities can generate realized foreign exchange losses which could impact the income distributions paid by the Fund. Additionally, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used exclusively.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt; &lt;b&gt;  Counterparty and Issuer Credit Risk.&lt;/b&gt; The financial condition of an issuer of a debt security or other instrument or a counterparty to a derivative or other contract may cause such issuer or counterparty to default, become unable to pay interest or principal due or otherwise fail to honor its obligations. While the Fund attempts to limit credit and counterparty exposure in a manner consistent with its investment objective, the value of an investment in the Fund may change quickly and without warning in response to issuer or counterparty defaults and changes in the credit ratings of the Fund&amp;#8217;s portfolio investments. &lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt; &lt;b&gt;Currency Exchange Rate Risk.&lt;/b&gt; The Fund invests a significant portion of its assets in investments denominated in euros, or in securities that provide exposure to euros, currency exchange rates or interest rates denominated in euros. Changes in currency exchange rates and the relative value of the euro will affect the value of the Fund&amp;#8217;s investment and the value of your Fund shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt; &lt;b&gt;Derivatives Investment Risk.&lt;/b&gt; The Fund may invest in derivatives. Derivatives are subject to a number of risks described elsewhere in this Prospectus, such as interest rate risk, market risk, and credit risk. They also involve the risk that changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, or that the counterparty to a derivative contract might default on its obligations.

Recent market events affecting several of the EU member countries have adversely affected the sovereign debt issued by those countries, and ultimately may lead to a decline in the value of the euro.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt; &lt;b&gt; Foreign Securities Risk.&lt;/b&gt; The Fund invests a significant portion of its assets in non-U.S. securities and instruments, or in securities that provide exposure to such securities and instruments. Investments in non-U.S. securities and instruments involve certain risks that may not be present with investments in U.S. securities, including the risk of loss due to foreign currency fluctuations or to political or economic instability.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt; &lt;b&gt; Geographic Concentration in Europe.&lt;/b&gt; Because the Fund concentrates its investments in Europe, the Fund&amp;#8217;s performance is expected to be closely tied to social, political, and economic conditions within Europe and to be more volatile than the performance of more geographically diversified funds. Most developed countries in Western Europe are members of the European Union (EU), and many are also members of the European Monetary Union (EMU), which requires compliance with restrictions on inflation rates, deficits, and debt levels. Unemployment in certain European nations is historically high. In addition, the tight fiscal and monetary controls necessary to join the EMU can significantly affect every country in Europe. These and other factors could have a negative impact on the Fund&amp;#8217;s performance and increase the volatility of an investment in the Fund.&lt;/li&gt;&lt;/ul&gt;&lt;ul type="square"&gt;&lt;li style="margin-left:-20px"&gt; &lt;b&gt;High Yield Securities Risk.&lt;/b&gt; Higher yielding, high risk debt securities, sometimes referred to as junk bonds, may present additional risk because these securities may be less liquid and present more credit risk than investment grade bonds.

Within these regions, the Fund intends to invest in a subset of the following markets: Brazil, Chile, China, Colombia, Czech Republic, Hungary, India, Indonesia, Malaysia, Mexico, Peru, the Philippines, Poland, Russia, South Africa, South Korea, Taiwan, Thailand, and Turkey. This list may change based on market developments. The Fund attempts to achieve exposure to the most liquid currencies within each of the three broad regions, while at the same time maintaining geographic and economic diversity across these regions. The specific set of currencies is selected on the annual assessment date each year (typically in August) and generally remains the same throughout the year. The selected currencies are equally weighted in terms of U.S. dollar value at the annual assessment date. The Fund is rebalanced quarterly in order to maintain this equal weighting. In order to maintain geographic diversity, the Fund&amp;#8217;s exposure to each of the three broad geographic regions is limited to 55% of its total asset value on the annual assessment date and at each quarterly rebalancing. More frequent rebalancing may occur in response to significant market events. A significant event might include, for example, market conditions that significantly disrupt liquidity or result in the reclassification of a currency (from emerging to developed, for example). Currencies that generally would be considered liquid may be ineligible for investment or dropped from the Fund as a result of government action or other market events if the Fund&amp;#8217;s adviser believes doing so would be in the best interest of the Fund.&lt;br/&gt;&lt;br/&gt;  Because the market for money market securities in the selected emerging markets generally is less liquid and accessible to foreign investors than corresponding markets in more developed countries, the Fund intends to achieve exposure to these markets by investing primarily in short-term U.S. money market securities and forward currency contracts and swaps of the constituent currencies. The combination of U.S. money market securities with forward currency contracts and currency swaps is designed to provide exposure equivalent to money market securities denominated in currencies of the selected markets in which the Fund invests. In aggregate, the Fund&amp;#8217;s investments should create exposure that is economically similar to a basket of money market securities denominated in each of the selected currencies. A forward currency contract is an agreement to buy or sell a specific currency at a future date at a price set at the time of the contract. A currency swap is an agreement between two parties to exchange one currency for another at a future rate. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. A repurchase agreement is a transaction in which the Fund purchases securities or other obligations from a bank or securities dealer and simultaneously commits to resell them to a counterparty at an agreed-upon date or upon demand and at a price reflecting a market rate of interest unrelated to the coupon rate or maturity of the purchased obligations. &lt;br/&gt;&lt;br/&gt; In order to attempt to reduce interest rate risk, the Fund generally will maintain a weighted average portfolio maturity of 90 days or less with respect to the money market securities in its portfolio. The Fund will not purchase any security with a remaining maturity of more than 397 calendar days. All U.S. money market securities acquired by the Fund will be rated in the upper two short-term ratings by at least two nationally recognized statistical rating organizations (&amp;#8220;NRSROs&amp;#8221;) or, if unrated, deemed to be of equivalent quality. The Fund does not seek to preserve capital in U.S. dollars. &lt;br/&gt;&lt;br/&gt; The decision to secure exposure directly or indirectly will be a function of, among other things, market accessibility, credit exposure, and tax ramifications for foreign investors. If the Fund pursues direct investment, eligible investments include short-term securities issued by emerging market governments and their agencies or instrumentalities, bank debt obligations and time deposits, bankers&amp;#8217; acceptances, commercial paper, short-term corporate debt obligations, mortgage-backed securities, and asset-backed securities. &lt;br/&gt;&lt;br/&gt; The Fund will invest, under normal circumstances, at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in investments whose combined performance is tied economically to selected emerging market countries. If, subsequent to an investment, the 80% requirement is no longer met, the Fund&amp;#8217;s future investments will be made in a manner that will bring the Fund into compliance with this policy. The Trust will provide shareholders with sixty (60) days&amp;#8217; prior notice of any change to this policy for the Fund.</rr:StrategyNarrativeTextBlock>
