Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund's performance. During the most recent fiscal year ended May 31, 2012, the Fund's portfolio turnover rate was 30% of the average value of its portfolio.

The Example does not take into account brokerage commissions that you pay when purchasing or selling Shares of the Fund. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund, using a low cost "passive" or "indexing" investment approach, seeks to replicate, before the Fund's fees and expenses, the performance of the Index. The Index is composed of all liquid (as defined by the criteria set forth below) American depositary receipts ("ADRs") and global depositary receipts ("GDRs") of certain countries that are represented in the Index. As of August 31, 2012, the Index was comprised of 38 constituents. The Index tracks the performance of depositary receipts, in ADR or GDR form, that trade on the London Stock Exchange ("LSE"), New York Stock Exchange ("NYSE"), NYSE Arca, Inc. ("NYSE Arca"), NYSE AMEX, and Nasdaq Stock Market ("NASDAQ") of companies from countries that are defined as the "Frontier Market." The Bank of New York Mellon, the Fund's index provider ("BNY Mellon" or the "Index Provider"), defines Frontier Market countries based upon an evaluation of gross domestic product growth, per capita income growth, experienced and expected inflation rates, privatization of infrastructure and social inequalities. The countries currently are: Argentina, Bahrain, Jordan, Kuwait, Lebanon, Oman, Qatar, United Arab Emirates, Egypt, Ghana, Kenya, Malawi, Mauritius, Morocco, Nigeria, Tunisia, Zimbabwe, Bulgaria, Croatia, Czech Republic, Estonia, Georgia, Kazakhstan, Latvia, Lithuania, Poland, Romania, Slovak Republic, Slovenia, Ukraine, Bangladesh, Pakistan, Papua New Guinea, Sri Lanka, Vietnam, Peru, Chile, Colombia, Ecuador, Jamaica, Panama and Trinidad & Tobago. The universe of potential Index constituents includes all liquid ADRs and GDRs which meet the criteria set forth under "Index Construction" with respect to trading volume and market capitalization. As of August 31, 2012, potential Index constituents include securities with free-float market capitalizations greater than $100 million which may include securities of all categories of market capitalizations, as defined by the Index Provider. The Fund will invest at least 80% of its total assets in ADRs and GDRs that comprise the Index or in the securities underlying such ADRs and GDRs. The Fund also will normally invest at least 80% of its total assets in securities of issuers from Frontier Market countries (whether directly or through ADRs or GDRs), as defined by the Index Provider from time to time in the manner set forth above. The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in these policies or the Index. The Board of Trustees of the Trust may change the Fund's investment strategy and other policies without shareholder approval, except as otherwise indicated. The Fund may invest directly in one or more underlying securities represented by the ADRs or GDRs comprising the Index under the following limited circumstances: (a) when market conditions result in the underlying security providing improved liquidity relative to the ADR or GDR; (b) when an ADR or GDR is trading at a significantly different price than its underlying security; or (c) the timing of trade execution is improved due to the local market in which an underlying security is traded being open at different times than the market in which the security's corresponding ADR or GDR is traded. The Investment Adviser seeks a correlation over time of 0.95 or better between the Fund's performance and the performance of the Index. A figure of 1.00 would represent perfect correlation. The Fund generally will invest in all of the securities comprising the Index in proportion to their weightings in the Index. However, under various circumstances, it may not be possible or practicable to purchase all of the securities in the Index in those weightings. In those circumstances, the Fund may purchase a sample of the securities in the Index in proportions expected by the Investment Adviser to replicate generally the performance of the Index as a whole. There may also be instances in which the Investment Adviser may choose to overweight another security in the Index, or purchase (or sell) securities not in the Index which the Investment Adviser believes are appropriate to substitute for one or more Index components, in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index.
Strategy Portfolio Concentration [Text]	rr_StrategyPortfolioConcentration	The Fund, using a low cost "passive" or "indexing" investment approach, seeks to replicate, before the Fund's fees and expenses, the performance of the Index. The Index is composed of all liquid (as defined by the criteria set forth below) American depositary receipts ("ADRs") and global depositary receipts ("GDRs") of certain countries that are represented in the Index.
Risk [Heading]	rr_RiskHeading	Principal Investment Risks
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	Investors should consider the following risk factors and special considerations associated with investing in the Fund, which may cause you to lose money. Investment Risk. An investment in the Fund is subject to investment risk, including the possible loss of the entire principal amount that you invest. Equity Risk. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by the Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund. In addition, equity securities of an issuer in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns. Foreign Investment Risk. The Fund's investments in non-U.S. issuers may involve unique risks compared to investing in securities of U.S. issuers, including less market liquidity, generally greater market volatility than U.S. securities and less complete financial information than for U.S. issuers. In addition, adverse political, economic or social developments could undermine the value of the Fund's investments or prevent the Fund from realizing the full value of its investments. Financial reporting standards for companies based in foreign markets differ from those in the United States. Finally, the value of the currency of the country in which the Fund has invested could decline relative to the value of the U.S. dollar, which may affect the value of the investment to U.S. investors. The Fund will not enter into transactions to hedge against declines in the value of the Fund's assets that are denominated in a foreign currency. Risks of Investing In Frontier Securities. Frontier market countries are emerging market countries. Investment in securities in emerging market countries involves risks not associated with investments in securities in developed countries, including risks associated with expropriation and/or nationalization, political or social instability, armed conflict, the impact on the economy as a result of civil war, religious or ethnic unrest and the withdrawal or non-renewal of any license enabling the Fund to trade in securities of a particular country, confiscatory taxation, restrictions on transfers of assets, lack of uniform accounting, auditing and financial reporting standards, less publicly available financial and other information, diplomatic development which could affect U.S. investments in those countries and potential difficulties in enforcing contractual obligations. Emerging markets are subject to greater market volatility, lower trading volume, political and economic instability, uncertainty regarding the existence of trading markets and more governmental limitations on foreign investment than more developed markets. In addition, securities in emerging markets may be subject to greater price fluctuations than securities in more developed markets. There may be less information publicly available with regard to emerging market issuers and such issuers are not subject to the uniform accounting, auditing and financial reporting standards applicable to U.S. issuers. There may be no single centralized securities exchange on which securities are traded in emerging market countries and the systems of corporate governance to which companies in emerging markets are subject may be less advanced than that to which U.S. issuers are subject, and therefore, shareholders in such companies may not receive many of the protections available to shareholders of U.S. issuers. Securities law in many emerging markets countries is relatively new and unsettled. Therefore, laws regarding foreign investment in emerging market securities, securities regulation, title to securities, and shareholder rights may change quickly and unpredictably. In addition, the enforcement of systems of taxation at federal, regional and local levels in emerging market countries may be inconsistent, and subject to sudden change. Frontier countries generally have smaller economies or less developed capital markets than traditional emerging markets, and, as a result, the risks of investing in emerging market countries are magnified in frontier countries. The economies of frontier countries are less correlated to global economic cycles than those of their more developed counterparts and their markets have low trading volumes and the potential for extreme price volatility and illiquidity. This volatility may be further heightened by the actions of a few major investors. For example, a substantial increase or decrease in cash flows of mutual funds investing in these markets could significantly affect local stock prices and, therefore, the price of Fund Shares. These factors make investing in frontier countries significantly riskier than in other countries and any one of them could cause the price of the Fund's Shares to decline. Governments of many frontier countries in which the Fund may invest may exercise substantial influence over many aspects of the private sector. In some cases, the governments of such frontier countries may own or control certain companies. Accordingly, government actions could have a significant effect on economic conditions in a frontier country and on market conditions, prices and yields of securities in the Fund's portfolio. Moreover, the economies of frontier countries may be heavily dependent upon international trade and, accordingly, have been and may continue to be, adversely affected by trade barriers, exchange controls, managed adjustments in relative currency values and other protectionist measures imposed or negotiated by the countries with which they trade. These economies also have been and may continue to be adversely affected by economic conditions in the countries with which they trade. Certain foreign governments in countries in which the Fund may invest levy withholding or other taxes on dividend and interest income. Although in some countries a portion of these taxes are recoverable, the non-recovered portion of foreign withholding taxes will reduce the income received from investments in such countries. From time to time, certain of the companies in which the Fund may invest may operate in, or have dealings with, countries subject to sanctions or embargoes imposed by the U.S. government and the United Nations and/or countries identified by the U.S. government as state sponsors of terrorism. A company may suffer damage to its reputation if it is identified as a company which operates in, or has dealings with, countries subject to sanctions or embargoes imposed by the U.S. government and the United Nations and/or countries identified by the U.S. government as state sponsors of terrorism. As an investor in such companies, the Fund will be indirectly subject to those risks. Investment in equity securities of issuers operating in certain frontier countries is restricted or controlled to varying degrees. These restrictions or controls may at times limit or preclude foreign investment in equity securities of issuers operating in certain frontier countries and increase the costs and expenses of the Fund. Certain frontier countries require governmental approval prior to investments by foreign persons, limit the amount of investment by foreign persons in a particular issuer, limit the investment by foreign persons only to a specific class of securities of an issuer that may have less advantageous rights than the classes available for purchase by domiciliaries of the countries and/or impose additional taxes on foreign investors. Certain frontier countries may also restrict investment opportunities in issuers in industries deemed important to national interests. Frontier countries may require governmental approval for the repatriation of investment income, capital or the proceeds of sales of securities by foreign investors, such as the Fund. In addition, if deterioration occurs in a frontier country's balance of payments, the country could impose temporary restrictions on foreign capital remittances. The Fund could be adversely affected by delays in, or a refusal to grant, any required governmental approval for repatriation of capital, as well as by the application to the Fund of any restrictions on investments. Investing in local markets in frontier countries may require the Fund to adopt special procedures, seek local government approvals or take other actions, each of which may involve additional costs to the Fund. As of August 31, 2012, a significant percentage of the Index is comprised of securities of companies from Chile, Colombia and Egypt. To the extent that the Index is focused on securities of any one country, including Chile, Colombia and Egypt, the value of the Index, and thus the Fund, will be especially affected by adverse developments in such country, including the risks described above. Political Risk. Certain of the frontier countries may be subject to a greater degree of political and social instability than is the case in more developed countries. Such instability may result from, among other things, authoritarian governments or military involvement in political and economic decision-making, including changes in government through extra-constitutional means, popular unrest associated with demands for improved political, economic and social conditions, internal insurgencies, hostile relations with neighboring countries and ethnic, religious and racial disaffection. Some frontier countries may be affected by a greater degree of public corruption and crime, including organized crime. Licensing, Custody and Settlement Risk. Approval of governmental authorities may be required prior to investing in the securities of companies based in certain frontier countries. Delays in obtaining such an approval would delay investments in the particular country. Rules adopted under the Investment Company Act of 1940, as amended, permit a fund to maintain its foreign securities and cash in the custody of certain eligible non-U.S. banks and securities depositories. Certain banks in foreign countries that are eligible foreign sub-custodians may be recently organized or otherwise lack extensive operating experience. In addition, in certain countries there may be legal restrictions or limitations on the ability of the Fund to recover assets held in custody by a foreign sub-custodian in the event of the bankruptcy of the sub-custodian. Settlement systems in emerging markets may be less well organized than in developed markets. Thus there may be a risk that settlement may be delayed and that cash or securities of the Fund may be in jeopardy because of failures of or defects in the systems. Under the laws of certain countries in which the Fund may invest, the Fund may be required to release local shares before receiving cash payment or may be required to make cash payment prior to receiving local shares. Certain countries in which the Fund may invest utilize share blocking schemes. Share blocking refers to a practice, in certain foreign markets, where voting rights related to an issuer's securities are predicated on these securities being blocked from trading at the custodian or sub-custodian level, for a period of time around a shareholder meeting. These restrictions have the effect of prohibiting securities to potentially be voted (or having been voted), from trading within a specified number of days before, and in certain instances, after the shareholder meeting. Share blocking may prevent the Fund from buying or selling securities for a period of time. During the time that shares are blocked, trades in such securities will not settle. The specific practices may vary by market and the blocking period can last from a day to several weeks, typically terminating on a date established at the discretion of the issuer. Once blocked, the only manner in which to remove this block would be to withdraw a previously cast vote, or to abstain from voting all together. The process for having a blocking restriction lifted can be quite onerous, with the particular requirements varying widely by country. In addition, in certain countries, the block cannot be removed. Share blocking may present operational challenges for the Fund and Authorized Participants, including the effect that an imposed block would have on pending trades. Pending trades may be caused to fail and could potentially remain unsettled for an extended period of time. Fails may also expose the transfer agent and the Fund to "Buy In" situations in which if unable to deliver shares after a certain period of time, a counter party has the right to go to market, purchase a security at the current market price and have any additional expense borne by the fund or transfer agent. As a result of the ramifications of voting ballots in share blocking proxy markets, the Investment Adviser, on behalf of the Fund, reserves the right to abstain from voting proxies in share blocking proxy markets. Financial Services Sector Risk. The financial services industries are subject to extensive government regulation, can be subject to relatively rapid change due to increasingly blurred distinctions between service segments, and can be significantly affected by availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, and price competition. In addition, the deterioration of the credit markets since late 2007 generally has caused an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. In particular, events in the financial sector since late 2008 have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. This situation has created instability in the financial markets and caused certain financial services companies to incur large losses. Numerous financial services companies have experienced substantial declines in the valuations of their assets, taken action to raise capital (such as the issuance of debt or equity securities), or even ceased operations. These actions have caused the securities of many financial services companies to experience a dramatic decline in value. Issuers that have exposure to the real estate, mortgage and credit markets have been particularly affected by the foregoing events and the general market turmoil, and it is uncertain whether or for how long these conditions will continue. Non-Correlation Risk. The Fund has historically experienced differences between the Fund's return and that of the Index ("tracking error"), which often have been substantial and exceed those experienced by many other ETFs. The tracking error experienced by the Fund has generally arisen from the application of the Fund's fair valuation policies to certain underlying securities which, despite being listed on a stock exchange (as set forth under "Principal Investment Strategies"), may not experience trades on a daily basis. The underlying Index is not required to fair value its constituents. In addition, the Fund's return may not match the return of the Index for a number of other reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Index. The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. If the Fund utilizes a sampling approach or otherwise holds instruments other than those which constitute the Index, its return may not correlate as well with the return on the Index, as would be the case if it purchased all of the securities in the Index with the same weightings as the Index. Small and Medium-Sized Company Risk. Investing in securities of small and medium-sized companies involves greater risk than is customarily associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of larger, more established companies. These securities may have returns that vary, sometimes significantly, from the overall stock market. Micro-Cap Company Risk. Micro-cap securities involve substantially greater risks of loss and price fluctuations because their earnings and revenues tend to be less predictable (and some companies may be experiencing significant losses), and their share prices tend to be more volatile and their markets less liquid than companies with larger market capitalizations. Micro-cap companies may be newly formed or in the early stages of development, with limited product lines, markets or financial resources and may lack management depth. In addition, there may be less public information available about these companies. The shares of micro-cap companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the future ability to sell these securities. Also, it may take a long time before the Fund realizes a gain, if any, on an investment in a micro-cap company. Passive Management Risk. Unlike many investment companies, the Fund is not "actively" managed. Therefore, it would not necessarily sell a security because the security's issuer was in financial trouble unless that security is removed from the Index. Issuer-Specific Changes. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than that of larger issuers. Non-Diversified Fund Risk. The Fund is considered non-diversified and can invest a greater portion of assets in securities of individual issuers than a diversified fund. Even though no single security weight may exceed 10% of the Index at the time of each quarterly rebalance, changes in the market value of the Index's constituent securities may result in the Fund being invested in the securities of individual issuers (and making additional such investments in the case of creations of additional Creation Units) in greater proportions. As a result, changes in the market value of a single investment could cause greater fluctuations in share price than would occur in a diversified fund. The Fund's Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund has not been guaranteed, sponsored, recommended, or approved by the United States, or any agency, instrumentality or officer of the United States, has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is not guaranteed by and is not otherwise an obligation of any bank or insured depository institution.

[1] The Fund has adopted a Distribution and Service (12b-1) Plan pursuant to which the Fund may bear a 12b-1 fee not to exceed 0.25% per annum of the Fund's average daily net assets. However, no such fee is currently paid by the Fund and the Board of Trustees has adopted a resolution that no such fee will be paid for at least 12 months from the date of this prospectus.

[2] The Fund's Investment Adviser has contractually agreed to reimburse Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, a portion of the Fund's licensing fees, offering costs up to 0.25% of average net assets, brokerage commissions and other trading expenses, taxes and extraordinary expenses such as litigation and other expenses not incurred in the ordinary course of the Fund's business) from exceeding 0.65% of average net assets per year (the "Expense Cap"), at least until December 31, 2015, and prior to such date the Investment Adviser may not terminate the arrangement without the approval of the Board of Trustees. For a period of five years subsequent to the Fund's commencement of operations, the Investment Adviser may recover from the Fund expenses reimbursed during the prior three years if the Fund's expense ratio, including the recovered expenses, falls below the Expense Cap. To the extent that the Fund incurs expenses that are excluded from the Expense Cap, the Fund's expense ratio will exceed the Expense Cap.

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund, using a low cost "passive" or "indexing" investment approach, will seek to replicate, before the Fund's fees and expenses, the performance of the Index. The Index is designed to measure the performance of high dividend-paying companies in the shipping industry. CME Group Index Services LLC ("CME Indexes" or the "Index Provider") uses a rules-based methodology to rank companies by yield that are involved in the shipping industry globally that primarily transport goods and materials. The Index Provider determines whether a company is "high-dividend paying" by ranking it relative to other companies in the shipping industry based upon indicated annual yield (most recent distribution annualized and divided by the current share price). The Index Provider considers a company to be in the shipping industry if its revenues are derived primarily from shipping activities (excluding companies solely involved in transporting passengers). As of the date of this Prospectus, a significant percentage (i.e., greater than 25%) of the Index was comprised of companies in the industrials and energy sectors. The companies in the Index may be located in any country, including those classified as emerging markets. The Index constituents are weighted based on their float-adjusted market capitalization and, as of August 31, 2012, the market capitalizations of the 25 stocks included in the Index range from $100 million to $2 billion, which includes micro-, small-, mid- and large-capitalization stocks as defined by the Index Provider. As of that date, the Index constituents' countries of domicile were represented (in approximate market capitalization) in the Index as follows: United States 40.22%, Denmark 18.54%, Japan 12.92%, China 7.28%, Singapore 7.10%, Hong Kong 6.98%, Greece 5.19% and Norway 1.76%. The Fund will at all times invest at least 90% of its total assets in common stock, American depositary receipts ("ADRs"), global depositary receipts ("GDRs") and master limited partnerships ("MLPs") that comprise the Index and the underlying stocks in respect of the ADRs and GDRs in the Index. The depositary receipts included in the Index may be sponsored or unsponsored. The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Index. The Board of Trustees of the Trust may change the Fund's investment strategy and other policies without shareholder approval, except as otherwise indicated. The Fund may invest directly in one or more underlying securities represented by depositary receipts included in the Index under the following limited circumstances: (a) when market conditions result in the underlying security providing improved liquidity relative to the depositary receipt; (b) when a depositary receipt is trading at a significantly different price than its underlying security; or (c) the timing of trade executions is improved.   The Investment Adviser seeks a correlation over time of 0.95 or better between the Fund's performance and the performance of the Index. A figure of 1.00 would represent perfect correlation. The Fund generally will invest in all of the securities comprising the Index in proportion to their weightings in the Index. However, under various circumstances, it may not be possible or practicable to purchase all of the securities in the Index in those weightings. In those circumstances, the Fund may purchase a sample of the securities in the Index in proportions expected by the Investment Adviser to replicate generally the performance of the Index as a whole. There may also be instances in which the Investment Adviser may choose to overweight another stock in the Index, or purchase (or sell) securities not in the Index which the Investment Adviser believes are appropriate to substitute for one or more Index components, in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index. Prior to July 27, 2011, the Fund sought to replicate, before the Fund's fees and expenses, the performance of the Delta Global Shipping Index.
Strategy Portfolio Concentration [Text]	rr_StrategyPortfolioConcentration	The Fund, using a low cost "passive" or "indexing" investment approach, will seek to replicate, before the Fund's fees and expenses, the performance of the Index. The Index is designed to measure the performance of high dividend-paying companies in the shipping industry.
Risk [Heading]	rr_RiskHeading	Principal Investment Risks
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	Investors should consider the following risk factors and special considerations associated with investing in the Fund, which may cause you to lose money. Investment Risk. An investment in the Fund is subject to investment risk, including the possible loss of the entire principal amount that you invest. Equity Risk. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by the Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund. In addition, common stock of an issuer in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns. Shipping Industry Risk. Due to the composition of the Index, the Fund will concentrate its investments in securities of companies in the shipping industry. Accordingly, the Fund may be subject to more risks than if it were broadly diversified over numerous industries and sectors of the economy. Companies in the shipping industry are subject to volatile fluctuations in the price and supply of energy fuels, steel, raw materials and other products transported by containerships. In addition, changes in seaborne transportation patterns, weather patterns and events including hurricane activity, commodities prices, international politics and conflicts, port congestion, canal closures, embargoes and labor strikes can significantly affect companies involved in the maritime shipping of crude oil, dry bulk and container cargo. Industrials Sector Risk. The stock prices of companies in the industrials sector are affected by supply and demand both for their specific product or service and for industrials sector products in general. The products of manufacturing companies may face product obsolescence due to rapid technological developments and frequent new product introduction. Government regulation, world events and economic conditions may affect the performance of companies in the industrials sector. Companies in the industrials sector may be at risk for environmental damage and product liability claims. Energy Sector Risk. The profitability of companies in the energy sector is related to worldwide energy prices, exploration, and production spending. Such companies also are subject to risks of changes in exchange rates, government regulation, world events, depletion of resources and economic conditions, as well as market, economic and political risks of the countries where energy companies are located or do business. Foreign Investment Risk. The Fund's investments in non-U.S. issuers may involve unique risks compared to investing in securities of U.S. issuers, including less market liquidity, generally greater market volatility than U.S. securities and less complete financial information than for U.S. issuers. In addition, adverse political, economic or social developments could undermine the value of the Fund's investments or prevent the Fund from realizing the full value of its investments. Financial reporting standards for companies based in foreign markets differ from those in the United States. Finally, the value of the currency of the country in which the Fund has invested could decline relative to the value of the U.S. dollar, which may affect the value of the investment to U.S. investors. The Fund will not enter into transactions to hedge against declines in the value of the Fund's assets that are denominated in a foreign currency. Emerging market countries are countries that major international financial institutions, such as the World Bank, generally consider to be less economically mature than developed nations. Emerging market countries can include every nation in the world except the United States, Canada, Japan, Australia, New Zealand and most countries located in Western Europe. Investing in foreign countries, particularly emerging market countries, entails the risk that news and events unique to a country or region will affect those markets and their issuers. Countries with emerging markets may have relatively unstable governments, may present the risks of nationalization of businesses, restrictions on foreign ownership and prohibitions on the repatriation of assets. The economies of emerging markets countries also may be based on only a few industries, making them more vulnerable to changes in local or global trade conditions and more sensitive to debt burdens or inflation rates. European Economic Risk. The Economic and Monetary Union of the European Union (the "EU") requires member countries to comply with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have a significant adverse effect on the economies of EU member countries and on major trading partners outside Europe. The European financial markets have recently experienced volatility and have been adversely affected by concerns about economic downturns, credit rating downgrades, rising government debt levels and possible default on or restructuring of government debt in several European countries, including Greece, Ireland, Italy, Portugal and Spain. A default or debt restructuring by any European country would adversely impact holders of that country's debt, and sellers of credit default swaps linked to that country's creditworthiness (which may be located in countries other than those listed in the previous sentence). These events have adversely affected the value and exchange rate of the euro and may continue to significantly affect the economies of every country in Europe, including EU member countries that do not use the euro and non-EU member countries. Risks Related to Investing in Japan. The growth of Japan's economy has historically lagged that of its Asian neighbors and other major developed economies. The Japanese economy is heavily dependent on international trade and has been adversely affected by trade tariffs, other protectionist measures, competition from emerging economies and the economic conditions of its trading partners. Japan's relations with its neighbors, particularly China, North Korea, South Korea and Russia, have at times been strained due to territorial disputes, historical animosities and defense concerns. Most recently, the Japanese government has shown concern over the increased nuclear and military activity by North Korea. Strained relations may cause uncertainty in the Japanese markets and adversely affect the overall Japanese economy in times of crisis. China has become an important trading partner with Japan, yet the countries' political relationship has become strained. Should political tension increase, it could adversely affect the economy, especially the export sector, and destabilize the region as a whole. Historically, Japan has been subject to unpredictable national politics and may experience frequent political turnover. Future political developments may lead to changes in policy that might adversely affect the Fund's investments. In addition, the Japanese economy faces several concerns, including a financial system with large levels of nonperforming loans, over-leveraged corporate balance sheets, extensive cross-ownership by major corporations, a changing corporate governance structure, and large government deficits. The Japanese yen has fluctuated widely at times and any increase in its value may cause a decline in exports that could weaken the economy. Furthermore, Japan has an aging workforce. It is a labor market undergoing fundamental structural changes, as traditional lifetime employment clashes with the need for increased labor mobility, which may adversely affect Japan's economic competitiveness. Japan also remains heavily dependent on oil imports, and higher commodity prices could therefore have a negative impact on the economy. Furthermore, Japanese corporations often engage in high levels of corporate leveraging, extensive cross-purchases of the securities of other corporations and are subject to a changing corporate governance structure. Japan is located in a part of the world that has historically been prone to natural disasters such as earthquakes, volcanoes and tsunamis and is economically sensitive to environmental events. In March of 2011 Japan suffered a major earthquake and tsunami, which resulted in a nuclear crisis and which significantly impacted the Japanese economy. Japan's economy is still recovering from the impact of these incidents, and is therfore particularly subject to certain risks as described above. In particular, the effects of radiation caused by the nuclear meltdown remain a depressant to farming and agriculture in northern Japan. Japan remains subject to the risk of additional environmental events or natural disasters. Small and Medium- Sized Company Risk. Investing in securities of small and medium-sized companies involves greater risk than is customarily associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of larger, more established companies. These securities may have returns that vary, sometimes significantly, from the overall stock market. Master Limited Partnership Risk. Investments in securities of MLPs involve risks that differ from an investment in common stock. Holders of the units of MLPs have more limited control and limited rights to vote on matters affecting the partnership. There are also certain tax risks associated with an investment in units of MLPs. In addition, conflicts of interest may exist between common unit holders, subordinated unit holders and the general partner of a MLP, including a conflict arising as a result of incentive distribution payments. Micro-Cap Company Risk. Micro-cap stocks involve substantially greater risks of loss and price fluctuations because their earnings and revenues tend to be less predictable (and some companies may be experiencing significant losses), and their share prices tend to be more volatile and their markets less liquid than companies with larger market capitalizations. Micro-cap companies may be newly formed or in the early stages of development, with limited product lines, markets or financial resources and may lack management depth. In addition, there may be less public information available abou these companies. The shares of micro-cap companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the future ability to sell these securities. Also, it may take a long time before the Fund realizes a gain, if any, on an investment in a micro-cap company. Non-Correlation Risk. The Fund's return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Index. The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. If the Fund utilizes a sampling approach or otherwise holds investments other than those that comprise the Index, its return may not correlate as well with the return on the Index, as would be the case if it purchased all of the securities in the Index with the same weightings as the Index. Passive Management Risk. Unlike many investment companies, the Fund is not "actively" managed. Therefore, it would not necessarily sell a security because the security's issuer was in financial trouble unless that security is removed from the Index. Issuer-Specific Changes. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than that of larger issuers. Non-Diversified Fund Risk. The Fund is considered non-diversified and can invest a greater portion of assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. The Fund's Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund has not been guaranteed, sponsored, recommended, or approved by the United States, or any agency, instrumentality or officer of the United States, has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is not guaranteed by and is not otherwise an obligation of any bank or insured depository institution.

Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund, using a low cost "passive" or "indexing" investment approach, will seek to replicate, before the Fund's fees and expenses, the performance of the AlphaShares China Yuan Bond Index. The Index is a rules-based index comprised of, as of August 31, 2012, approximately 57 securities. The securities in the Index are bonds that are eligible for investment by U.S. and other foreign investors and denominated in Chinese Yuan, whether issued by Chinese or non-Chinese issuers and traded in the secondary market, a market commonly referred to as the "Dim Sum" bond market. The Fund will not invest in onshore securities in mainland China. The Index includes bonds issued by mainland Chinese entities with a minimum of Yuan 1 billion outstanding par value, as well as bonds issued by non-mainland Chinese entities (which have no minimum outstanding par value requirement). All of the bond issues or issuers must have an investment grade rating by Moody's Investors Service ("Moody's"), Standard & Poor's Ratings Services ("S&P") and/or Fitch Ratings of Baa3/BBB-/BBB-, respectively, or better. Bonds must have a minimum of one year maturity for inclusion in the Index. Only bonds that pay a fixed periodic coupon, that delay coupon payments until maturity, zero coupon bonds or floating rate bonds are eligible for inclusion in the Index. The interest rates of the floating rate bonds in the Index typically adjust based upon the then-current Shanghai Interbank Offered Rate on a quarterly basis. The Chinese Yuan-denominated debt securities in which the Fund invests are currently not listed on a stock exchange or a primary securities market where trading is conducted on a regular basis. The Index was created by AlphaShares, LLC ("AlphaShares" or the "Index Provider") and is maintained by Interactive Data Corporation (the "Index Administrator"). The Fund will invest at least 80% of its total assets in fixed income securities that comprise the Index. The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Index. The Board of Trustees of the Trust may change the Fund's investment strategies and other policies without shareholder approval, except as otherwise indicated. Guggenheim Funds Investment Advisors, LLC (the "Investment Adviser"), J.P. Morgan Investment Management, Inc. ("JPMIM") and JF International Management Inc. ("JFIMI") (the "Investment Sub-Advisers") seek a correlation over time of 0.95 or better between the Fund's performance and the performance of the Index. A figure of 1.00 would represent perfect correlation. The Fund expects to use a sampling approach in seeking to achieve its investment objective. Sampling means that the Investment Adviser and Investment Sub-Advisers use quantitative analysis to select securities from the Index universe to obtain a representative sample of securities that resemble the Index in terms of key risk factors, performance attributes and other characteristics. These characteristics include maturity, credit quality, duration and other financial characteristics of fixed income securities. The quantity of holdings in the Fund will be based on a number of factors, including the asset size of the Fund, potential transaction costs in acquiring particular securities, the anticipated impact of particular index securities on the performance of the Index and the availability of particular securities in the secondary market. However, the Fund may use replication to achieve its objective if practicable. There may also be instances in which the Investment Adviser and Investment Sub-Advisers may choose to overweight another security in the Index, or purchase (or sell) securities not in the Index which the Investment Adviser and Investment Sub-Advisers believe are appropriate to substitute for one or more Index components, in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index. If the Index concentrates in an industry or group of industries, the Fund's investments will be concentrated accordingly. As of the date of this Prospectus, a significant percentage (i.e., greater than 30%) of the Index was comprised of companies in the financial services and government-related issues sectors. Within the financial services sector, the Index was concentrated in the Chinese banking industry. The financial services sector includes companies that are principally engaged in the business of providing financial services and products, including banking, investment services, insurance and real estate finance services. The government-related issues sector includes debt securities issued by the Chinese government, Chinese government agencies and instrumentalities, and supranational agencies. Sector and industry allocation is not a factor in the construction of the Index and, accordingly, the Index's allocations to any particular sector or industry may increase or decrease over time.

Risk [Heading]	rr_RiskHeading	Principal Investment Risks
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	Investors should consider the following risk factors and special considerations associated with investing in the Fund, which may cause you to lose money. Investment Risk. An investment in the Fund is subject to investment risk, including the possible loss of the entire principal amount that you invest. Foreign Issuers Risk. The Fund invests in Chinese Yuan-denominated bonds of foreign corporations, governments, agencies and instrumentalities and supranational agencies which have different risks than investing in U.S. companies. These include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries, and potential restrictions of the flow of international capital. Foreign companies may be subject to less governmental regulation than U.S. issuers. Moreover, individual foreign economies may differ favorably or unfavorably from the U.S. economy in such respects as growth of gross domestic product, rate of inflation, capital investment, resource self-sufficiency and balance of payment options. China Investment Risk. The Index includes only bonds open to foreign ownership by U.S. investors. Accordingly, the Index does not include, and the Fund will not invest in, securities traded in mainland China. As a result, returns achieved by non-Chinese investors, such as the Fund, could differ from those available to domestic investors in mainland China. While the Index does not include securities traded in mainland China, Yuan-denominated bonds issued by mainland Chinese government, government agency and instrumentality, and bank issuers trading on the secondary market will be included in the Index. Investing in Chinese bonds involves additional risks, including: the economy of China differs, often unfavorably, from the U.S. economy in such respects as structure, general development, government involvement, wealth distribution, rate of inflation, growth rate, allocation of resources and capital reinvestment; the central government has historically exercised substantial control over virtually every sector of the Chinese economy through administrative regulation and/or state ownership; and actions of the Chinese central and local government authorities continue to have a substantial effect on economic conditions in China. It is difficult for non-Chinese investors to directly access securities issued by Chinese issuers because of investment and trading restrictions. These limitations and restrictions may impact the availability, liquidity, and pricing of certain Yuan-denominated securities. Currency Risk. Changes in currency exchange rates and the relative value of the Chinese Yuan will affect the value of the Fund's investment and the value of your Shares. Because the Fund's net asset value ("NAV") is determined on the basis of U.S. dollars, the U.S. dollar value of your investment in the Fund may go down if the value of the Chinese Yuan depreciates against the U.S. dollar. This is true even if the Chinese Yuan value of securities in the Fund's portfolio goes up. 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. The Yuan is currently not a freely convertible currency. 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 government'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. In addition, 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, which could 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. Further, the Chinese government's imposition of restrictions on the repatriation of Yuan out of mainland China may limit the depth of the offshore Yuan market and reduce the liquidity of the Fund's investments. These and other factors could have a negative impact on the Fund's performance and increase the volatility of an investment in the Fund. The Chinese government's policies on currency, control and repatriation restrictions are subject to change, and the Fund's or the shareholders' position may be adversely affected. Limited Pool of Investments. The Index consists of Chinese-Yuan denominated debt securities issued or distributed outside mainland China. However, the quantity of such debt securities that are available for inclusion in the Index, and thus for the Fund to invest in, is currently limited, and the remaining duration of such instruments may be short. This may adversely affect the Fund's return and performance. The Chinese government may restrict the ability of non-Chinese issuers to issue Yuan-denominated bonds in the "Dim Sum" market and the supply of eligible securities for the Index, and thus the Fund, may accordingly be limited. Moreover, the "Dim Sum" bond market is a relatively new market and there can be no guarantee that this market will continue to grow. Credit/Default Risk. Credit risk is the risk that issuers or guarantors of debt instruments are unable or unwilling to make timely interest and/or principal payments or otherwise honor their obligations. Debt instruments are subject to varying degrees of credit risk, which may be reflected in credit ratings. Credit rating downgrades and defaults (failure to make interest or  principal payment) may potentially reduce the Fund's income and share price. Chinese-Yuan denominated debt securities that the Fund invests in are typically unsecured debt obligations and are not supported by any collateral. The Fund will accordingly be fully exposed to the credit/insolvency risk of its counterparties as an unsecured creditor. The Fund may also encounter difficulties or delays in enforcing its rights against the issuers of Chinese-Yuan denominated debt securities as such issuers may be incorporated outside the United States and subject to foreign laws. The Fund may invest in bond issues or issuers with an investment grade rating by Moody's, S&P and/or Fitch Ratings of Baa3/BBB-/BBB-, respectively. Securities with such ratings may possess certain speculative characteristics, and the ability of issuers of such securities to make timely payments of interest and principal may be adversely impacted by adverse changes in general economic conditions, changes in the financial condition of the issuers and price fluctuations in response to changes in interest rates. Interest Rate Risk. As interest rates rise, the value of fixed-income securities held by the Fund are likely to decrease. Securities with longer durations tend to be more sensitive to interest rate changes, making them more volatile than securities with shorter durations. Asset Class Risk. The bonds in the Fund's portfolio may underperform the returns of other bonds or indexes that track other industries, markets, asset classes or sectors. Different types of bonds and indexes tend to go through different performance cycles than the general bond market. Call Risk/Prepayment Risk. During periods of falling interest rates, an issuer of a callable bond may exercise its right to pay principal on an obligation earlier than expected. This may result in the Fund reinvesting proceeds at lower interest rates, resulting in a decline in the Fund's income. Extension Risk. Extension risk is the risk that an issuer will exercise its right to pay principal on an obligation later than expected. This may happen when there is a rise in interest rates. Under these circumstances, the value of the obligation will decrease and the Fund's performance may suffer from its inability to invest in higher yielding securities. Income Risk. Income risk is the risk that falling interest rates will cause the Fund's income to decline. Liquidity Risk. Liquidity risk exists when particular investments are difficult to purchase or sell. If the Fund invests in securities that become illiquid, Fund returns may be reduced because the Fund may be unable to sell the illiquid securities at an advantageous time or price. The Chinese-Yuan denominated debt securities in which the Fund invests are currently not listed on a stock exchange or a primary securities market where trading is conducted on a regular basis. There is also no guarantee that market making arrangements will be in place at all times to make a market and quote a price for all Chinese-Yuan denominated debt securities. If a security for which there is not an active secondary market is removed from the Index, the Fund may need to sell such security at a substantial discount in order to rebalance its holdings to match the Index and the Fund may suffer losses in trading such security. Even if a secondary market exists, the price at which the Chinese-Yuan denominated debt securities are traded may be higher or lower than the initial subscription price due to many factors, including the prevailing interest rates. Further, the bid and offer spread of the price of Chinese-Yuan denominated debt securities may be high, and the Fund may therefore incur significant trading costs and may even suffer losses when selling such investments. Moreover, the "Dim Sum" bond market is a relatively new market and there can be no guarantee that trading will continue to thrive or increase in this market. Financial Services Sector Risk. The financial services industries are subject to extensive government regulation, can be subject to relatively rapid change due to increasingly blurred distinctions between service segments, and can be significantly affected by availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, and price competition. In addition, the deterioration of the credit markets since late 2007 generally has caused an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. In particular, events in the financial sector since late 2008 have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. This situation has created instability in the financial markets and caused certain financial services companies to incur large losses. Numerous financial services companies have experienced substantial declines in the valuations of their assets, taken action to raise capital (such as the issuance of debt or equity securities), or even ceased operations. These actions have caused the securities of many financial services companies to experience a dramatic decline in value. Issuers that have exposure to the real estate, mortgage and credit markets have been particularly affected by the foregoing events and the general market turmoil, and it is uncertain whether or for how long these conditions will continue. Government-Related Issues Risk. Investments in government-related securities involve special risks. The governmental agency or instrumentality or supranational agency that controls the repayment of the debt may be unwilling or unable to repay the principal and/or interest when due in accordance with the terms of such securities due to such factors as: its cash flow situation; the extent of its foreign reserves; the availability of sufficient foreign exchange on the date a payment is due; the relative size of the debt service burden to the economy as a whole; the agency's policy toward principal international lenders; or political constraints to which a government-related debtor may be subject. Government-related debtors may also be dependent on expected disbursements from foreign governments, multilateral agencies and other entities to reduce principal and interest arrears on their debt. The failure of a government-related issuer to achieve specified levels of economic performance or repay principal or interest when due may result in the cancellation of third-party commitments to lend funds to the government-related debtor, which may further impair such debtor's ability or willingness to service its debts. If an issuer of government-related debt defaults on payments of principal and/or interest, the Fund may have limited legal recourse against the issuer and/or guarantor. In addition, even if a foreign government subsequently guarantees the obligations of a government-related issuer or otherwise provides sufficient support to allow a government-related issuer to meet its obligations, that may cause the securities of such issuer to be considered as having been issued by the applicable foreign government directly, which may make it difficult for the Fund to comply with certain diversification requirements under the Internal Revenue Code of 1986, as amended (the "Code"). During periods of economic uncertainty, the market prices of government-related debt, and the Fund's NAV, may be more volatile than prices of corporate debt obligations. Any material changes in the political, economic, regulatory or social conditions prevailing in China may have a material adverse effect on the Chinese economy. The market prices of government-related debt and the Fund's NAV may, therefore, be more volatile than prices of corporate debt obligations. Chinese Banking Industry Risk. The banking industry a highly regulated industry in China and is subject to laws regulating all aspects of the banking business, including the Commercial Banking Law and related rules and regulations. The principal regulators of the Chinese banking industry include the China Banking Regulatory Commission (CBRC) and the People's Bank of China (PBOC) and, in exercising their authority, these regulators are given wide discretion. The Chinese banking regulatory regime is currently undergoing significant changes, including changes in the rules and regulations, as it moves toward a more transparent regulatory process. Some of these changes may have an adverse impact on the performance of Chinese banks that issued Yuan-denominated debt securities and thus may adversely affect their capacity to honor their commitments under the Yuan-denominated debt securities to their creditors, which may include the Fund. As some of these laws, rules, regulations or policies are relatively new, there is uncertainty regarding their interpretation and application. Failure to comply with any of these laws, rules, regulations or policies may result in fines, restrictions on business activities or, in extreme cases, suspension or revocation of business licenses of Chinese banks. In addition, future laws, rules, regulations or policies, or the interpretation of existing or future laws, rules, regulations or policies, including accounting policies and standards, may have a material adverse affect on the business, financial condition and results of operations of Chinese banks. Future legislative or regulatory changes, including deregulation, may have a material adverse effect on Chinese banks' business, financial condition and results of operations, and the Chinese banks may not be able to achieve full compliance with any such new laws, rules, regulations or policies. Risks of Change in Government Support and Regulatory Regime governing "Dim Sum" bonds. Issuance of "Dim Sum" bonds in Hong Kong is subject to Hong Kong laws and regulations. The Chinese central government currently views Hong Kong as one of the key offshore Chinese Yuan centers and has established a cooperative relationship with the Hong Kong government to develop the Hong Kong Chinese Yuan bond market. However, there is no assurance that the Chinese central government will continue to encourage issuance of Chinese Yuan bonds overseas and any change in the Chinese central government's policy and/or the legal or regulatory regime in Hong Kong governing the issuance of "Dim Sum" bonds may have an adverse impact on the Fund's investments. Non-Correlation Risk. The Fund's return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Index. Since the Index constituents may vary on a monthly basis, the Fund's costs associated with rebalancing may be greater than those incurred by other exchange-traded funds that track indices whose composition changes less frequently. The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. Since the Fund utilizes a sampling approach, its return may not correlate as well with the return on the Index as would be the case if it purchased all of the securities in the Index with the same weightings as the Index. Concentration Risk. If the Index concentrates in an industry or group of industries the Fund's investments will be concentrated accordingly. In such event, the value of the Fund's Shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries. Passive Management Risk. Unlike many investment companies, the Fund is not "actively" managed. Therefore, it would not necessarily sell a security because the security's issuer was in financial trouble or in default, or whose credit rating was downgraded, unless that security is removed from the Index. Issuer-Specific Changes. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than that of larger issuers. Non-Diversified Fund Risk. The Fund is considered non-diversified and can invest a greater portion of assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. Risk of Cash Transactions. In certain instances, unlike most ETFs, the Fund may effect creations and redemptions for cash, rather than in-kind. As a result, an investment in the Fund may be less tax-efficient than an investment in a more conventional ETF. ETFs generally are able to make in-kind redemptions and avoid being taxed on gain on the distributed portfolio securities at the Fund level. Because the Fund may effect redemptions for cash, rather than in-kind distributions, it may be required to sell portfolio securities in order to obtain the cash needed to distribute redemption proceeds. If the Fund recognizes gain on these sales, this generally will cause the Fund to recognize gain it might not otherwise have recognized, or to recognize such gain sooner than would otherwise be required if it were to distribute portfolio securities in-kind. The Fund generally intends to distribute these gains to shareholders to avoid being taxed on this gain at the Fund level and otherwise comply with the special tax rules that apply to it. This strategy may cause shareholders to be subject to tax on gains they would not otherwise be subject to, or at an earlier date than, if they had made an investment in a different ETF. Moreover, cash transactions may have to be carried out over several days if the securities market is relatively illiquid and may involve considerable brokerage fees and taxes. These brokerage fees and taxes, which will be higher than if the Fund sold and redeemed its Shares principally in-kind, will be passed on to purchasers and redeemers of Creation Units in the form of creation and redemption transaction fees. In addition, these factors may result in wider spreads between the bid and the offered prices of the Fund's Shares than for more conventional ETFs. The Fund's Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund has not been guaranteed, sponsored, recommended, or approved by the United States, or any agency, instrumentality or officer of the United States, has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is not guaranteed by and is not otherwise an obligation of any bank or insured depository institution.

Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund, using a low cost "passive" or "indexing" investment approach, seeks to replicate, before the Fund's fees and expenses, the performance of the Index. All securities in the Index are selected from the universe of global timber companies. Beacon Indexes LLC ("Beacon" or the "Index Provider") defines global timber companies as firms who own or lease forested land and harvest the timber from such forested land for commercial use and sale of wood-based products, including lumber, pulp or other processed or finished goods such as paper and packaging. Potential Index constituents include securities with market capitalizations greater than $300 million, which includes securities of all categories of market capitalizations, as determined by Beacon. The Fund will invest at least 90% of its total assets in common stock, American depositary receipts ("ADRs") and global depositary receipts ("GDRs") that comprise the Index and depositary receipts representing common stocks included in the Index (or underlying securities representing the ADRs and GDRs included in the Index). The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Index. The Board of Trustees of the Trust may change the Fund's investment strategy and other policies without shareholder approval, except as otherwise indicated. The Fund may invest directly in one or more underlying securities represented by the ADRs included in the Index under the following limited circumstances: (a) when market conditions result in the underlying security providing more liquidity than the ADR; (b) when an ADR is trading at a significantly different price than its underlying security; or (c) the timing of trade execution is improved due to the local market in which an underlying security is traded being open at different times than the market in which the security's corresponding ADR is traded. The Investment Adviser seeks a correlation over time of 0.95 or better between the Fund's performance and the performance of the Index. A figure of 1.00 would represent perfect correlation. The Fund generally will invest in all of the securities comprising the Index in proportion to their weightings in the Index. However, under various circumstances, it may not be possible or practicable to purchase all of the securities in the Index in those weightings. In those circumstances, the Fund may purchase a sample of the securities in the Index in proportions expected by the Investment Adviser to replicate generally the performance of the Index as a whole. There may also be instances in which the Investment Adviser may choose to overweight another security in the Index, or purchase (or sell) securities not in the Index which the Investment Adviser believes are appropriate to substitute for one or more Index components, in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index.

Investment Risk. An investment in the Fund is subject to investment risk, including the possible loss of the entire principal amount that you invest. Equity Risk. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by the Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund. In addition, common stock of an issuer in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns. Global Timber Industry Risk. As the Index is comprised of issuers in the global timber industry, the Fund is therefore focused in that industry. Accordingly, the Fund may be subject to more risks than if it were broadly diversified over numerous industries and sectors of the economy. The market value of securities of global timber companies may be affected by numerous factors, including events occurring in nature and international politics. For example, the volume and value of timber that can be harvested from timberlands may be limited by natural disasters and other events such as fire, volcanic eruptions, insect infestation, disease, ice storms, wind storms, flooding, other weather conditions and other causes. In periods of poor logging conditions, global timber companies may harvest less timber than expected. Global timber companies involved in the forest, paper and packaging products industries are highly competitive globally, including significant competition from non-wood and engineered wood products, and no single company is dominant. These industries have suffered, and continue to suffer, from excess capacity. Global timber companies are subject to many federal, state and local environmental, health and safety laws and regulations, particularly with respect to the restoration and reforestation of timberlands, harvesting timber near waterways, discharges of pollutants and emissions, and the management, disposal and remediation of hazardous substances or other contaminants. Political risks and the other risks to which foreign securities are subject may also affect domestic companies in which the Fund may invest if they have significant operations or investments in foreign countries. In particular, tariffs, quotas or trade agreements can also affect the markets for products of global timber companies, particularly wood products. In addition, rising interest rates and general economic conditions may affect the demand for timber products. Foreign Investment Risk. The Fund's investments in non-U.S. issuers may involve unique risks compared to investing in securities of U.S. issuers, including less market liquidity, generally greater market volatility than U.S. securities and less complete financial information than for U.S. issuers. In addition, adverse political, economic or social developments could undermine the value of the Fund's investments or prevent the Fund from realizing the full value of its investments. Financial reporting standards for companies based in foreign markets differ from those in the United States. Finally, the value of the currency of the country in which the Fund has invested could decline relative to the value of the U.S. dollar, which may affect the value of the investment to U.S. investors. The Fund will not enter into transactions to hedge against declines in the value of the Fund's assets that are denominated in a foreign currency. Emerging market countries are countries that major international financial institutions, such as the World Bank, generally consider to be less economically mature than developed nations. Emerging market countries can include every nation in the world except the United States, Canada, Japan, Australia, New Zealand and most countries located in Western Europe. Investing in foreign countries, particularly emerging market countries, entails the risk that news and events unique to a country or region will affect those markets and their issuers. Countries with emerging markets may have relatively unstable governments, may present the risks of nationalization of businesses, restrictions on foreign ownership and prohibitions on the repatriation of assets. The economies of emerging markets countries also may be based on only a few industries, making them more vulnerable to changes in local or global trade conditions and more sensitive to debt burdens or inflation rates. Local securities markets may trade a small number of securities and may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of holdings difficult or impossible at times. European Economic Risk. The Economic and Monetary Union of the European Union (the "EU") requires member countries to comply with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have a significant adverse effect on the economies of EU member countries and on major trading partners outside Europe. The European financial markets have recently experienced volatility and have been adversely affected by concerns about economic downturns, credit rating downgrades, rising government debt levels and possible default on or restructuring of government debt in several European countries, including Greece, Ireland, Italy, Portugal and Spain. A default or debt restructuring by any European country would adversely impact holders of that country's debt, and sellers of credit default swaps linked to that country's creditworthiness (which may be located in countries other than those listed in the previous sentence). These events have adversely affected the value and exchange rate of the euro and may continue to significantly affect  the economies of every country in Europe, including EU member countries that do not use the euro and non-EU member countries. Basic Materials Sector Risk. Companies in the basic materials sector could be adversely affected by commodity price volatility, exchange rates, import controls and increased competition. Production of industrial materials often exceeds demand as a result of overbuilding or economic downturns, leading to poor investment returns. Companies in the basic materials sector are at risk for environmental damage and product liability claims. Companies in the basic materials sector may be adversely affected by depletion of resources, technical progress, labor relations, and government regulations. Financial Services Sector Risk. The financial services industries are subject to extensive government regulation, can be subject to relatively rapid change due to increasingly blurred distinctions between service segments, and can be significantly affected by availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, and price competition. In addition, the deterioration of the credit markets since late 2007 generally has caused an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. In particular, events in the financial sector since late 2008 have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. This situation has created instability in the financial markets and caused certain financial services companies to incur large losses. Numerous financial services companies have experienced substantial declines in the valuations of their assets, taken action to raise capital (such as the issuance of debt or equity securities), or even ceased operations. These actions have caused the securities of many financial services companies to experience a dramatic decline in value. Issuers that have exposure to the real estate, mortgage and credit markets have been particularly affected by the foregoing events and the general market turmoil, and it is uncertain whether or for how long these conditions will continue. Small and Medium-Sized Company Risk. Investing in securities of small and medium-sized companies involves greater risk than is customarily associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of larger, more established companies. These securities may have returns that vary, sometimes significantly, from the overall stock market. Non-Correlation Risk. The Fund's return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Index. The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. If the Fund utilizes a sampling approach, its return may not correlate as well with the return on the Index, as would be the case if it purchased all of the securities in the Index with the same weightings as the Index. Passive Management Risk. Unlike many investment companies, the Fund is not "actively" managed. Therefore, it would not necessarily sell a security because the security's issuer was in financial trouble unless that security is removed from the Index. Issuer-Specific Changes. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of  the market as a whole. The value of securities of smaller issuers can be more volatile than that of larger issuers. Non-Diversified Fund Risk. The Fund is considered non-diversified and can invest a greater portion of assets in securities of individual issuers than a diversified fund. Even though no single security weight may exceed 4.5% of the Index at the time of each quarterly rebalance, changes in the market value of the Index's constituent securities may result in the Fund being invested in the securities of individual issuers (and making additional such investments in the case of creations of additional Creation Units) in greater proportions. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. The Fund's Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund has not been guaranteed, sponsored, recommended, or approved by the United States, or any agency, instrumentality or officer of the United States, has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is not guaranteed by and is not otherwise an obligation of any bank or insured depository institution.

However, no such fee is currently paid by the Fund and the Board of Trustees has adopted a resolution that no such fee will be paid for at least 12 months from the date of this prospectus.

[2] The Fund's Investment Adviser has contractually agreed to reimburse Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, a portion of the Fund's licensing fees, offering costs up to 0.25% of average net assets, brokerage commissions and other trading expenses, taxes and extraordinary expenses such as litigation and other expenses not incurred in the ordinary course of the Fund's business) from exceeding 0.65% of average net assets per year (the "Expense Cap"), at least until December 31, 2015, and prior to such date the Investment Adviser may not terminate the arrangement without the approval of the Board of Trustees. For a period of five years subsequent to the Fund's commencement of operations, the Investment Adviser may recover from the Fund expenses reimbursed during the prior three years if the Fund's expense ratio, including the recovered expenses, falls below the Expense Cap. To the extent that the Fund incurs expenses that are excluded from the Expense Cap, the Fund's expense ratio will exceed the Expense Cap.

Guggenheim Yuan Bond ETF (Prospectus Summary) | Guggenheim Yuan Bond ETF

Guggenheim Yuan Bond ETF

Investment Objective

The Fund seeks investment results that correspond generally to the performance,
before the Fund's fees and expenses, of a Yuan bond index called the AlphaShares
China Yuan Bond Index (the "Index").

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors purchasing Shares in the secondary
market may be subject to costs (including customary brokerage commissions)
charged by their broker.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		Guggenheim Yuan Bond ETF
Management fees (comprehensive management fee)		0.65%
Distribution and service (12b-1) fees	[1]	none
Other expenses		none
Total annual Fund operating expenses		0.65%

Example

This Example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. The Example does not take into account
brokerage commissions that you pay when purchasing or selling Shares of the Fund.

The Example assumes that you invest $10,000 in the Fund for the time periods
indicated and then redeem all of your shares at the end of those periods. The
Example also assumes that your investment has a 5% return each year and that the
Fund's operating expenses remain the same. Although your actual costs may be
higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	Expense Example, with Redemption, 1 Year	Expense Example, with Redemption, 3 Years	Expense Example, with Redemption, 5 Years	Expense Example, with Redemption, 10 Years
Guggenheim Yuan Bond ETF	66	262	474	1,085

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells
securities (or "turns over" its portfolio). A higher portfolio turnover rate may
indicate higher transaction costs and may result in higher taxes when Shares are
held in a taxable account. These costs, which are not reflected in annual fund
operating expenses or in the Example, affect the Fund's performance. During the
period September 22, 2011 (the Fund's commencement of operations) through May 31,
2012, the Fund's portfolio turnover was 54% of the average value of its portfolio.

Principal Investment Strategies

The Fund, using a low cost "passive" or "indexing" investment approach, will
seek to replicate, before the Fund's fees and expenses, the performance of the
AlphaShares China Yuan Bond Index. The Index is a rules-based index comprised
of, as of August 31, 2012, approximately 57 securities. The securities in the
Index are bonds that are eligible for investment by U.S. and other foreign
investors and denominated in Chinese Yuan, whether issued by Chinese or
non-Chinese issuers and traded in the secondary market, a market commonly
referred to as the "Dim Sum" bond market. The Fund will not invest in onshore
securities in mainland China. The Index includes bonds issued by mainland
Chinese entities with a minimum of Yuan 1 billion outstanding par value, as
well as bonds issued by non-mainland Chinese entities (which have no minimum
outstanding par value requirement). All of the bond issues or issuers must have
an investment grade rating by Moody's Investors Service ("Moody's"), Standard &
Poor's Ratings Services ("S&P") and/or Fitch Ratings of Baa3/BBB-/BBB-,
respectively, or better. Bonds must have a minimum of one year maturity for
inclusion in the Index. Only bonds that pay a fixed periodic coupon, that delay
coupon payments until maturity, zero coupon bonds or floating rate bonds are
eligible for inclusion in the Index. The interest rates of the floating rate
bonds in the Index typically adjust based upon the then-current Shanghai
Interbank Offered Rate on a quarterly basis. The Chinese Yuan-denominated debt
securities in which the Fund invests are currently not listed on a stock
exchange or a primary securities market where trading is conducted on a regular
basis. The Index was created by AlphaShares, LLC ("AlphaShares" or the "Index
Provider") and is maintained by Interactive Data Corporation (the "Index
Administrator"). The Fund will invest at least 80% of its total assets in fixed
income securities that comprise the Index. The Fund has adopted a policy that
requires the Fund to provide shareholders with at least 60 days notice prior to
any material change in this policy or the Index. The Board of Trustees of the
Trust may change the Fund's investment strategies and other policies without
shareholder approval, except as otherwise indicated.

Guggenheim Funds Investment Advisors, LLC (the "Investment Adviser"), J.P.
Morgan Investment Management, Inc. ("JPMIM") and JF International Management
Inc. ("JFIMI") (the "Investment Sub-Advisers") seek a correlation over time of
0.95 or better between the Fund's performance and the performance of the Index.
A figure of 1.00 would represent perfect correlation.

The Fund expects to use a sampling approach in seeking to achieve its investment
objective. Sampling means that the Investment Adviser and Investment Sub-Advisers
use quantitative analysis to select securities from the Index universe to obtain
a representative sample of securities that resemble the Index in terms of key
risk factors, performance attributes and other characteristics. These characteristics
include maturity, credit quality, duration and other financial characteristics of
fixed income securities. The quantity of holdings in the Fund will be based on a
number of factors, including the asset size of the Fund, potential transaction
costs in acquiring particular securities, the anticipated impact of particular
index securities on the performance of the Index and the availability of
particular securities in the secondary market. However, the Fund may use
replication to achieve its objective if practicable. There may also be instances
in which the Investment Adviser and Investment Sub-Advisers may choose to
overweight another security in the Index, or purchase (or sell) securities not
in the Index which the Investment Adviser and Investment Sub-Advisers believe
are appropriate to substitute for one or more Index components, in seeking to
accurately track the Index. In addition, from time to time securities are added
to or removed from the Index. The Fund may sell securities that are represented
in the Index or purchase securities that are not yet represented in the Index in
anticipation of their removal from or addition to the Index.

If the Index concentrates in an industry or group of industries, the Fund's
investments will be concentrated accordingly. As of the date of this Prospectus,
a significant percentage (i.e., greater than 30%) of the Index was comprised of
companies in the financial services and government-related issues sectors.
Within the financial services sector, the Index was concentrated in the Chinese
banking industry. The financial services sector includes companies that are
principally engaged in the business of providing financial services and
products, including banking, investment services, insurance and real estate
finance services. The government-related issues sector includes debt securities
issued by the Chinese government, Chinese government agencies and instrumentalities,
and supranational agencies. Sector and industry allocation is not a factor in the
construction of the Index and, accordingly, the Index's allocations to any particular
sector or industry may increase or decrease over time.

Principal Investment Risks

Investors should consider the following risk factors and special considerations
associated with investing in the Fund, which may cause you to lose money.

Investment Risk. An investment in the Fund is subject to investment risk,
including the possible loss of the entire principal amount that you invest.

Foreign Issuers Risk. The Fund invests in Chinese Yuan-denominated bonds
of foreign corporations, governments, agencies and instrumentalities and
supranational agencies which have different risks than investing in U.S.
companies. These include differences in accounting, auditing and financial
reporting standards, the possibility of expropriation or confiscatory taxation,
adverse changes in investment or exchange control regulations, political
instability which could affect U.S. investments in foreign countries, and
potential restrictions of the flow of international capital. Foreign companies
may be subject to less governmental regulation than U.S. issuers. Moreover,
individual foreign economies may differ favorably or unfavorably from the U.S.
economy in such respects as growth of gross domestic product, rate of inflation,
capital investment, resource self-sufficiency and balance of payment options.

China Investment Risk. The Index includes only bonds open to foreign ownership
by U.S. investors. Accordingly, the Index does not include, and the Fund will
not invest in, securities traded in mainland China. As a result, returns
achieved by non-Chinese investors, such as the Fund, could differ from those
available to domestic investors in mainland China. While the Index does not
include securities traded in mainland China, Yuan-denominated bonds issued by
mainland Chinese government, government agency and instrumentality, and bank
issuers trading on the secondary market will be included in the Index. Investing
in Chinese bonds involves additional risks, including: the economy of China
differs, often unfavorably, from the U.S. economy in such respects as structure,
general development, government involvement, wealth distribution, rate of inflation,
growth rate, allocation of resources and capital reinvestment; the central
government has historically exercised substantial control over virtually every
sector of the Chinese economy through administrative regulation and/or state
ownership; and actions of the Chinese central and local government authorities
continue to have a substantial effect on economic conditions in China. It is
difficult for non-Chinese investors to directly access securities issued by Chinese
issuers because of investment and trading restrictions. These limitations and
restrictions may impact the availability, liquidity, and pricing of certain
Yuan-denominated securities.

Currency Risk. Changes in currency exchange rates and the relative value of the
Chinese Yuan will affect the value of the Fund's investment and the value of
your Shares. Because the Fund's net asset value ("NAV") is determined on the
basis of U.S. dollars, the U.S. dollar value of your investment in the Fund
may go down if the value of the Chinese Yuan depreciates against the U.S.
dollar. This is true even if the Chinese Yuan value of securities in the Fund's
portfolio goes up. 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. The Yuan is
currently not a freely convertible currency. 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 government'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. In addition, 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, which could 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. Further, the Chinese government's imposition of restrictions on the
repatriation of Yuan out of mainland China may limit the depth of the offshore
Yuan market and reduce the liquidity of the Fund's investments. These and other
factors could have a negative impact on the Fund's performance and increase the
volatility of an investment in the Fund. The Chinese government's policies on
currency, control and repatriation restrictions are subject to change, and the
Fund's or the shareholders' position may be adversely affected.

Limited Pool of Investments. The Index consists of Chinese-Yuan denominated debt
securities issued or distributed outside mainland China. However, the quantity
of such debt securities that are available for inclusion in the Index, and thus
for the Fund to invest in, is currently limited, and the remaining duration of
such instruments may be short. This may adversely affect the Fund's return and
performance. The Chinese government may restrict the ability of non-Chinese
issuers to issue Yuan-denominated bonds in the "Dim Sum" market and the supply
of eligible securities for the Index, and thus the Fund, may accordingly be
limited. Moreover, the "Dim Sum" bond market is a relatively new market and
there can be no guarantee that this market will continue to grow.

Credit/Default Risk. Credit risk is the risk that issuers or guarantors of debt
instruments are unable or unwilling to make timely interest and/or principal
payments or otherwise honor their obligations. Debt instruments are subject to
varying degrees of credit risk, which may be reflected in credit ratings. Credit
rating downgrades and defaults (failure to make interest or  principal payment)
may potentially reduce the Fund's income and share price. Chinese-Yuan denominated
debt securities that the Fund invests in are typically unsecured debt obligations
and are not supported by any collateral. The Fund will accordingly be fully
exposed to the credit/insolvency risk of its counterparties as an unsecured
creditor. The Fund may also encounter difficulties or delays in enforcing its
rights against the issuers of Chinese-Yuan denominated debt securities as such
issuers may be incorporated outside the United States and subject to foreign laws.
The Fund may invest in bond issues or issuers with an investment grade rating by
Moody's, S&P and/or Fitch Ratings of Baa3/BBB-/BBB-, respectively. Securities with
such ratings may possess certain speculative characteristics, and the ability of
issuers of such securities to make timely payments of interest and principal may
be adversely impacted by adverse changes in general economic conditions, changes
in the financial condition of the issuers and price fluctuations in response to
changes in interest rates.

Interest Rate Risk. As interest rates rise, the value of fixed-income securities
held by the Fund are likely to decrease. Securities with longer durations tend
to be more sensitive to interest rate changes, making them more volatile than
securities with shorter durations.

Asset Class Risk. The bonds in the Fund's portfolio may underperform the returns
of other bonds or indexes that track other industries, markets, asset classes or
sectors. Different types of bonds and indexes tend to go through different
performance cycles than the general bond market.

Call Risk/Prepayment Risk. During periods of falling interest rates, an issuer
of a callable bond may exercise its right to pay principal on an obligation
earlier than expected. This may result in the Fund reinvesting proceeds at lower
interest rates, resulting in a decline in the Fund's income.

Extension Risk. Extension risk is the risk that an issuer will exercise its
right to pay principal on an obligation later than expected. This may happen
when there is a rise in interest rates. Under these circumstances, the value
of the obligation will decrease and the Fund's performance may suffer from its
inability to invest in higher yielding securities.

Income Risk. Income risk is the risk that falling interest rates will cause the
Fund's income to decline.

Liquidity Risk. Liquidity risk exists when particular investments are difficult
to purchase or sell. If the Fund invests in securities that become illiquid,
Fund returns may be reduced because the Fund may be unable to sell the illiquid
securities at an advantageous time or price. The Chinese-Yuan denominated debt
securities in which the Fund invests are currently not listed on a stock
exchange or a primary securities market where trading is conducted on a regular
basis. There is also no guarantee that market making arrangements will be in
place at all times to make a market and quote a price for all Chinese-Yuan
denominated debt securities. If a security for which there is not an active
secondary market is removed from the Index, the Fund may need to sell such
security at a substantial discount in order to rebalance its holdings to match
the Index and the Fund may suffer losses in trading such security. Even if a
secondary market exists, the price at which the Chinese-Yuan denominated debt
securities are traded may be higher or lower than the initial subscription price
due to many factors, including the prevailing interest rates. Further, the bid
and offer spread of the price of Chinese-Yuan denominated debt securities may be
high, and the Fund may therefore incur significant trading costs and may even
suffer losses when selling such investments. Moreover, the "Dim Sum" bond market
is a relatively new market and there can be no guarantee that trading will
continue to thrive or increase in this market.

Financial Services Sector Risk. The financial services industries are subject
to extensive government regulation, can be subject to relatively rapid change
due to increasingly blurred distinctions between service segments, and can be
significantly affected by availability and cost of capital funds, changes in
interest rates, the rate of corporate and consumer debt defaults, and price
competition. In addition, the deterioration of the credit markets since late
2007 generally has caused an adverse impact in a broad range of markets,
including U.S. and international credit and interbank money markets generally,
thereby affecting a wide range of financial institutions and markets. In
particular, events in the financial sector since late 2008 have resulted,
and may continue to result, in an unusually high degree of volatility in
the financial markets, both domestic and foreign. This situation has created
instability in the financial markets and caused certain financial services
companies to incur large losses. Numerous financial services companies have
experienced substantial declines in the valuations of their assets, taken action
to raise capital (such as the issuance of debt or equity securities), or even
ceased operations. These actions have caused the securities of many financial
services companies to experience a dramatic decline in value. Issuers that have
exposure to the real estate, mortgage and credit markets have been particularly
affected by the foregoing events and the general market turmoil, and it is
uncertain whether or for how long these conditions will continue.

Government-Related Issues Risk. Investments in government-related securities
involve special risks. The governmental agency or instrumentality or
supranational agency that controls the repayment of the debt may be unwilling or
unable to repay the principal and/or interest when due in accordance with the
terms of such securities due to such factors as: its cash flow situation; the
extent of its foreign reserves; the availability of sufficient foreign exchange
on the date a payment is due; the relative size of the debt service burden to
the economy as a whole; the agency's policy toward principal international
lenders; or political constraints to which a government-related debtor may
be subject. Government-related debtors may also be dependent on expected
disbursements from foreign governments, multilateral agencies and other entities
to reduce principal and interest arrears on their debt. The failure of a
government-related issuer to achieve specified levels of economic performance
or repay principal or interest when due may result in the cancellation of
third-party commitments to lend funds to the government-related debtor, which
may further impair such debtor's ability or willingness to service its debts.
If an issuer of government-related debt defaults on payments of principal and/or
interest, the Fund may have limited legal recourse against the issuer and/or
guarantor. In addition, even if a foreign government subsequently guarantees
the obligations of a government-related issuer or otherwise provides sufficient
support to allow a government-related issuer to meet its obligations, that may
cause the securities of such issuer to be considered as having been issued by
the applicable foreign government directly, which may make it difficult for the
Fund to comply with certain diversification requirements under the Internal
Revenue Code of 1986, as amended (the "Code"). During periods of economic
uncertainty, the market prices of government-related debt, and the Fund's NAV,
may be more volatile than prices of corporate debt obligations.

Any material changes in the political, economic, regulatory or social conditions
prevailing in China may have a material adverse effect on the Chinese economy.
The market prices of government-related debt and the Fund's NAV may, therefore,
be more volatile than prices of corporate debt obligations.

Chinese Banking Industry Risk. The banking industry a highly regulated industry
in China and is subject to laws regulating all aspects of the banking business,
including the Commercial Banking Law and related rules and regulations. The
principal regulators of the Chinese banking industry include the China Banking
Regulatory Commission (CBRC) and the People's Bank of China (PBOC) and, in
exercising their authority, these regulators are given wide discretion. The
Chinese banking regulatory regime is currently undergoing significant changes,
including changes in the rules and regulations, as it moves toward a more
transparent regulatory process. Some of these changes may have an adverse impact
on the performance of Chinese banks that issued Yuan-denominated debt securities
and thus may adversely affect their capacity to honor their commitments under
the Yuan-denominated debt securities to their creditors, which may include the
Fund.

As some of these laws, rules, regulations or policies are relatively new, there
is uncertainty regarding their interpretation and application. Failure to comply
with any of these laws, rules, regulations or policies may result in fines,
restrictions on business activities or, in extreme cases, suspension or
revocation of business licenses of Chinese banks. In addition, future laws,
rules, regulations or policies, or the interpretation of existing or future
laws, rules, regulations or policies, including accounting policies and
standards, may have a material adverse affect on the business, financial
condition and results of operations of Chinese banks. Future legislative or
regulatory changes, including deregulation, may have a material adverse effect
on Chinese banks' business, financial condition and results of operations, and
the Chinese banks may not be able to achieve full compliance with any such new
laws, rules, regulations or policies.

Risks of Change in Government Support and Regulatory Regime governing "Dim Sum"
bonds. Issuance of "Dim Sum" bonds in Hong Kong is subject to Hong Kong laws and
regulations. The Chinese central government currently views Hong Kong as one of
the key offshore Chinese Yuan centers and has established a cooperative relationship
with the Hong Kong government to develop the Hong Kong Chinese Yuan bond market.
However, there is no assurance that the Chinese central government will continue to
encourage issuance of Chinese Yuan bonds overseas and any change in the Chinese
central government's policy and/or the legal or regulatory regime in Hong Kong
governing the issuance of "Dim Sum" bonds may have an adverse impact on the Fund's
investments.

Non-Correlation Risk. The Fund's return may not match the return of the Index
for a number of reasons. For example, the Fund incurs a number of operating
expenses not applicable to the Index, and incurs costs in buying and selling
securities, especially when rebalancing the Fund's securities holdings to
reflect changes in the composition of the Index. Since the Index constituents
may vary on a monthly basis, the Fund's costs associated with rebalancing may
be greater than those incurred by other exchange-traded funds that track indices
whose composition changes less frequently.

The Fund may not be fully invested at times, either as a result of cash flows
into the Fund or reserves of cash held by the Fund to meet redemptions and
expenses. Since the Fund utilizes a sampling approach, its return may not
correlate as well with the return on the Index as would be the case if it
purchased all of the securities in the Index with the same weightings as the
Index.

Concentration Risk. If the Index concentrates in an industry or group of
industries the Fund's investments will be concentrated accordingly. In such
event, the value of the Fund's Shares may rise and fall more than the value
of shares of a fund that invests in securities of companies in a broader range
of industries.

Passive Management Risk. Unlike many investment companies, the Fund is not
"actively" managed. Therefore, it would not necessarily sell a security because
the security's issuer was in financial trouble or in default, or whose credit
rating was downgraded, unless that security is removed from the Index.

Issuer-Specific Changes. The value of an individual security or particular type
of security can be more volatile than the market as a whole and can perform
differently from the value of the market as a whole. The value of securities of
smaller issuers can be more volatile than that of larger issuers.

Non-Diversified Fund Risk. The Fund is considered non-diversified and can invest
a greater portion of assets in securities of individual issuers than a diversified
fund. As a result, changes in the market value of a single investment could cause
greater fluctuations in Share price than would occur in a diversified fund.

Risk of Cash Transactions. In certain instances, unlike most ETFs, the Fund may
effect creations and redemptions for cash, rather than in-kind. As a result, an
investment in the Fund may be less tax-efficient than an investment in a more
conventional ETF. ETFs generally are able to make in-kind redemptions and avoid
being taxed on gain on the distributed portfolio securities at the Fund level.
Because the Fund may effect redemptions for cash, rather than in-kind
distributions, it may be required to sell portfolio securities in order to
obtain the cash needed to distribute redemption proceeds. If the Fund recognizes
gain on these sales, this generally will cause the Fund to recognize gain it
might not otherwise have recognized, or to recognize such gain sooner than would
otherwise be required if it were to distribute portfolio securities in-kind. The
Fund generally intends to distribute these gains to shareholders to avoid being
taxed on this gain at the Fund level and otherwise comply with the special tax
rules that apply to it.

This strategy may cause shareholders to be subject to tax on gains they would
not otherwise be subject to, or at an earlier date than, if they had made an
investment in a different ETF. Moreover, cash transactions may have to be
carried out over several days if the securities market is relatively illiquid
and may involve considerable brokerage fees and taxes. These brokerage fees
and taxes, which will be higher than if the Fund sold and redeemed its Shares
principally in-kind, will be passed on to purchasers and redeemers of Creation
Units in the form of creation and redemption transaction fees. In addition,
these factors may result in wider spreads between the bid and the offered prices
of the Fund's Shares than for more conventional ETFs.

The Fund's Shares will change in value, and you could lose money by investing
in the Fund. The Fund may not achieve its investment objective. An investment
in the Fund has not been guaranteed, sponsored, recommended, or approved by the
United States, or any agency, instrumentality or officer of the United States,
has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is
not guaranteed by and is not otherwise an obligation of any bank or insured
depository institution.

Fund Performance

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund, using a low cost "passive" or "indexing" investment approach, seeks to replicate, before the Fund's fees and expenses, the performance of the Index. The Index is comprised of approximately 150 stocks selected, based on investment and other criteria, from a universe of international companies, global REITs, master limited partnerships ("MLPs"), Canadian royalty trusts, American depositary receipts ("ADRs") of emerging market companies and U.S. listed closed-end funds that invest in international companies, and at all times is comprised of at least 40% non-U.S. securities. The companies in the universe are selected using a proprietary strategy developed by Zacks Investment Research, Inc. ("Zacks" or the "Index Provider"). The Fund will invest at least 90% of its total assets in stocks that comprise the Index (and underlying securities representing the ADRs included in the Index). The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Index. The Board of Trustees of the Trust may change the Fund's investment strategy and other policies without shareholder approval, except as otherwise indicated. The Investment Adviser seeks a correlation over time of 0.95 or better between the Fund's performance and the performance of the Index. A figure of 1.00 would represent perfect correlation. The Fund generally will invest in all of the securities comprising the Index in proportion to their weightings in the Index. However, under various circumstances, it may not be possible or practicable to purchase all of the securities in the Index in those weightings. In those circumstances, the Fund may purchase a sample of the securities in the Index in proportions expected by the Investment Adviser to replicate generally the performance of the Index as a whole. There may also be instances in which  the Investment Adviser may choose to overweight another security in the Index, or purchase (or sell) securities not in the Index which the Investment Adviser believes are appropriate to substitute for one or more Index components, in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index. The Fund may invest directly in one or more underlying securities represented by the ADRs included in the Index under the following limited circumstances: (a) when market conditions result in the underlying security providing more liquidity than the ADR; (b) when an ADR is trading at a significantly different price than its underlying security; or (c) the timing of trade execution is improved due to the local market in which an underlying security is traded being open at different times than the market in which the security's corresponding ADR is traded.

Risk [Heading]	rr_RiskHeading	Principal Investment Risks
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	Investors should consider the following risk factors and special considerations associated with investing in the Fund, which may cause you to lose money. Investment Risk. An investment in the Fund is subject to investment risk, including the possible loss of the entire principal amount that you invest. Equity Risk. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by the Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund. In addition, common stock of an issuer in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns. Foreign Investment Risk. The Fund's investments in non-U.S. issuers may involve unique risks compared to investing in securities of U.S. issuers, including less market liquidity, generally greater market volatility than U.S. securities and less complete financial information than for U.S. issuers. In addition, adverse political, economic or social developments could undermine the value of the Fund's investments or prevent the Fund from realizing the full value of its investments. Financial reporting standards for companies based in foreign markets differ from those in the United States. Finally, the value of the currency of the country in which the Fund has invested could decline relative to the value of the U.S. dollar, which may affect the value of the investment to U.S. investors. The Fund will not enter into transactions to hedge against declines in the value of the Fund's assets that are denominated in a foreign currency. Emerging market countries are countries that major international financial institutions, such as the World Bank, generally consider to be less economically mature than developed nations. Emerging market countries can include every nation in the world except the United States, Canada, Japan, Australia, New Zealand and most countries located in Western Europe. Investing in foreign countries, particularly emerging market countries, entails the risk that news and events unique to a country or region will affect those markets and their issuers. Countries with emerging markets may have relatively unstable governments, may present the risks of nationalization of businesses, restrictions on foreign ownership and prohibitions on the repatriation of assets. The economies of emerging markets countries also may be based on only a few industries, making them more vulnerable to changes in local or global trade conditions and more sensitive to debt burdens or inflation rates. Local securities markets may trade a small number of securities and may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of holdings difficult or impossible at times. European Economic Risk. The Economic and Monetary Union of the European Union (the "EU") requires member countries to comply with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have a significant adverse effect on the economies of EU member countries and on major trading partners outside Europe. The European financial markets have recently experienced volatility and have been adversely affected by concerns about economic downturns, credit rating downgrades, rising government debt levels and possible default on or restructuring of government debt in several European countries, including Greece, Ireland, Italy, Portugal and Spain. A default or debt restructuring by any European country would adversely impact holders of that country's debt, and sellers of credit default swaps linked to that country's creditworthiness (which may be located in countries other than those listed in the previous sentence). These events have adversely affected the value and exchange rate of the euro and may continue to significantly affect the economies of every country in Europe, including EU member countries that do not use the euro and non-EU member countries. Financial Services Sector Risk. The financial services industries are subject to extensive government regulation, can be subject to relatively rapid change due to increasingly blurred distinctions between service segments, and can be significantly affected by availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, and price competition. In addition, the deterioration of the credit markets since late 2007 generally has caused an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. In particular, events in the financial sector since late 2008 have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. This situation has created instability in the financial markets and caused certain financial services companies to incur large losses. Numerous financial services companies have experienced substantial declines in the valuations of their assets, taken action to raise capital (such as the issuance of debt or equity securities), or even ceased operations. These actions have caused the securities of many financial services companies to experience a dramatic decline in value. Issuers that have exposure to the real estate, mortgage and credit markets have been particularly affected by the foregoing events and the general market turmoil, and it is uncertain whether or for how long these conditions will continue. Canadian Risk. As the Fund invests in Canadian royalty trusts and stocks listed on the Toronto Stock Exchange, the Fund is subject to the following risks:   Commodity Exposure Risk. The Canadian economy is very dependent on the demand   for, and supply and price of, natural resources. The Canadian market is   relatively concentrated in issuers involved in the production and distribution   of natural resources. There is a risk that any changes in these sectors could   have an adverse impact on the Canadian economy.   Reliance on Exports Risk. The Canadian economy is dependent on the economies of   the United States as a key trading partner. Reduction in spending on Canadian   products and services or changes in the U.S. economy may cause an impact in the   Canadian economy.   U.S. Economic Risk. The Canadian economy may be significantly affected by the   U.S. economy, given that the United States is Canada's largest trading partner   and foreign investor. Since the implementation of the North American Free Trade   Agreement (NAFTA) in 1994, total two-way merchandise trade between the United   States and Canada has more than doubled. To further this relationship, all three   NAFTA countries entered into The Security and Prosperity Partnership of North   America in March 2005, which addressed economic and security related issues.   The new agreement may further affect Canada's dependency on the U.S. economy.   Structural Risk (Political Risk). In addition, past periodic demands by the   Province of Quebec for sovereignty have significantly affected equity valuations   and foreign currency movements in the Canadian market. Canadian Royalty Trust Risk. As the Fund invests in Canadian royalty trusts, it is subject to the following risks applicable to Canadian royalty trusts:   Lack of diversification. The royalty trusts in which the Fund invests are   heavily invested in oil and gas.   Potential sacrifice of growth. Potential growth may be sacrificed because   revenue is passed on to a royalty trust's unit holders (such as the Fund),   rather than reinvested in the business.   No guarantees. Royalty trusts generally do not guarantee minimum distributions   or even return of capital. If the assets underlying a royalty trust do not   perform as expected, the royalty trust may reduce or even eliminate distributions.   The declaration of such distributions generally depends upon various factors,   including the operating performance and financial condition of the royalty trust   and general economic conditions.   Potential for tax recharacterization or changes. Under amendments to the Income   Tax Act (Canada) passed in 2007 (the "SIFT Rules"), certain trusts (defined as   "SIFT trusts") are taxable on certain income and gains on a basis similar to that   which applies to a corporation, with the result that tax efficiencies formerly   available in respect of an investment in the trust may cease to be available. A   royalty trust may be a SIFT trust. In addition, as a result of the SIFT Rules,   some trusts may undertake reorganization transactions, the costs of which may   affect the return earned on an investment in the trust. After any such conversion,   tax efficiencies that were formerly available in respect of an investment in the   trust may cease to be available. Accordingly, the SIFT Rules have had and may   continue to have an effect on the trading price of investments in royalty trusts,   and consequently could impact the value of Shares of the Fund. REIT Risk. The risks of investing in real estate companies include, among others, adverse changes in national, state or local real estate conditions; obsolescence of properties; changes in the availability, cost and terms of mortgage funds; and the impact of changes in environmental laws. In addition, the federal tax requirement that a REIT distribute substantially all of its net income to its shareholders may result in a REIT having insufficient capital for future expenditures. The value of a REIT can depend on the structure of and cash flow generated by the REIT. In addition, like mutual funds, REITs have expenses, including advisory and administration fees, that are paid by their shareholders. As a result, you will absorb duplicate levels of fees when the Fund invests in REITs. In addition, REITs are subject to certain provisions under federal tax law. The failure of a company to qualify as a REIT could have adverse consequences for the Fund, including significantly reducing return to the Fund on its investment in such company. Master Limited Partnership Risk. Investments in securities of MLPs involve risks that differ from an investment in common stock. Holders of the units of MLPs have more limited control and limited rights to vote on matters affecting the partnership. There are also certain tax risks associated with an investment in units of MLPs. In addition, conflicts of interest may exist between common unit holders, subordinated unit holders and the general partner of a MLP, including a conflict arising as a result of incentive distribution payments. Risks of Investing in Other Investment Companies. Shares of other investment companies are subject to the management fees and other expenses of those companies, and the purchase of shares of some investment companies (in the case of closed-end investment companies) may sometimes require the payment of substantial premiums above the value of such companies' portfolio securities or net asset values. The Fund must continue, at the same time, to pay its own management fees and expenses with respect to all of its investments, including shares of other investment companies. The securities of other investment companies may also be leveraged and will therefore be subject to certain leverage risks. Small and Medium-Sized Company Risk. Investing in securities of small and medium-sized companies involves greater risk than is customarily associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of larger, more established companies. These securities may have returns that vary, sometimes significantly, from the overall stock market. Non-Correlation Risk. The Fund's return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Index. Since the Index constituents may vary on a semi-annual basis, the Fund's costs associated with  rebalancing may be greater than those incurred by other exchange-traded funds that track indices whose composition changes less frequently. The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. If the Fund utilizes a sampling approach, its return may not correlate as well with the return on the Index, as would be the case if it purchased all of the securities in the Index with the same weightings as the Index. Passive Management Risk. Unlike many investment companies, the Fund is not "actively" managed. Therefore, it would not necessarily sell a security because the security's issuer was in financial trouble unless that security is removed from the Index. Issuer-Specific Changes. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than that of larger issuers. Non-Diversified Fund Risk. The Fund is considered non-diversified and can invest a greater portion of assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. The Fund's Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund has not been guaranteed, sponsored, recommended, or approved by the United States, or any agency, instrumentality or officer of the United States, has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is not guaranteed by and is not otherwise an obligation of any bank or insured depository institution.

Guggenheim China Real Estate ETF (Prospectus Summary) | Guggenheim China Real Estate ETF

Guggenheim China Real Estate ETF

Investment Objective

The Fund seeks investment results that correspond generally to the performance,
before the Fund's fees and expenses, of an equity index called the AlphaShares
China Real Estate Index (the "Index").

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors purchasing Shares in the secondary
market may be subject to costs (including customary brokerage commissions)
charged by their broker.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		Guggenheim China Real Estate ETF
Management Fees		0.50%
Distribution and service (12b-1) fees	[1]
Other expenses		0.85%
Total annual Fund operating expenses		1.35%
Expense Reimbursements	[2]	0.65%
Total annual Fund operating expenses after Expense Reimbursements		0.70%

Example

This Example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. The Example does not take into account
brokerage commissions that you pay when purchasing or selling Shares of the Fund.

The Example assumes that you invest $10,000 in the Fund for the time periods
indicated and then redeem all of your shares at the end of those periods. The
Example also assumes that your investment has a 5% return each year and that the
Fund's operating expenses remain the same. Although your actual costs may be
higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	Expense Example, with Redemption, 1 Year	Expense Example, with Redemption, 3 Years	Expense Example, with Redemption, 5 Years	Expense Example, with Redemption, 10 Years
Guggenheim China Real Estate ETF	72	278	652	1,703

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells
securities (or "turns over" its portfolio). A higher portfolio turnover rate may
indicate higher transaction costs and may result in higher taxes when Shares are
held in a taxable account. These costs, which are not reflected in annual fund
operating expenses or in the Example, affect the Fund's performance. During the
most recent fiscal year, the Fund's portfolio turnover rate was 14% of the
average value of its portfolio.

Principal Investment Strategies

The Fund, using a low cost "passive" or "indexing" investment approach, seeks
to replicate, before the Fund's fees and expenses, the performance of the Index.
The Index is designed to measure and monitor the performance of the investable
universe of publicly-traded companies and real estate investment trusts ("REITs")
deriving a majority of their revenues from real estate development, management
and/or ownership of property in China or the Special Administrative Regions of
China, which are Hong Kong and Macau. The Index was created by AlphaShares, LLC
("AlphaShares" or the "Index Provider") and is maintained by Standard & Poor's
(the "Index Administrator"). The Index includes equity securities of companies
of all categories of market capitalizations, as defined by AlphaShares (subject
to the minimum capitalization requirements set forth below under "Index
Construction").

The Index may include Hong Kong listed securities, including China H-shares
and Red Chips. China H-shares are issued by companies incorporated in mainland
China and listed on the Hong Kong Stock Exchange. Red Chip shares are issued by
companies with controlling Chinese shareholders that are incorporated outside
mainland China and listed on the Hong Kong Stock Exchange. The Index may also
include N-Shares, which are issued by companies based in mainland China and
listed on the NYSE Arca or NASDAQ. The Index will not include China A-Shares
(which are subject to substantial restrictions on foreign investment) or China
B-Shares (which offer a generally smaller market and limited liquidity), each
of which trade on the Shanghai Stock Exchange and the Shenzhen Stock Exchange.

The Fund will invest at least 90% of its total assets in common stocks, American
depositary receipts ("ADRs"), American depositary shares ("ADSs"), global
depositary receipts ("GDRs") and international depositary receipts ("IDRs") that
comprise the Index and depositary  receipts representing common stocks included
in the Index (or underlying securities representing the ADRs, ADSs, GDRs and IDRs
included in the Index). The Fund has adopted a policy that requires the Fund to
provide shareholders with at least 60 days notice prior to any material change
in this policy or the Index. The Board of Trustees of the Trust may change the
Fund's investment strategy and other policies without shareholder approval,
except as otherwise indicated.

The Fund may invest directly in one or more underlying securities represented by
the ADRs included in the Index under the following limited circumstances: (a)
when market conditions result in the underlying security providing more liquidity
than the ADR; (b) when an ADR is trading at a significantly different price than
its underlying security; or (c) the timing of trade execution is improved due to
the local market in which an underlying security is traded being open at different
times than the market in which the security's corresponding ADR is traded.

The Investment Adviser seeks a correlation over time of 0.95 or better between
the Fund's performance and the performance of the Index. A figure of 1.00 would
represent perfect correlation.

The Fund generally will invest in all of the securities comprising the Index in
proportion to their weightings in the Index. However, under various circumstances,
it may not be possible or practicable to purchase all of the securities in the
Index in those weightings. In those circumstances, the Fund may purchase a sample
of the securities in the Index in proportions expected by the Investment Adviser
to replicate generally the performance of the Index as a whole. There may also be
instances in which the Investment Adviser may choose to overweight another security
in the Index, or purchase (or sell) securities not in the Index which the Investment
Adviser believes are appropriate to substitute for one or more Index components, in
seeking to accurately track the Index. In addition, from time to time securities
are added to or removed from the Index. The Fund may sell securities that are
represented in the Index or purchase securities that are not yet represented in
the Index in anticipation of their removal from or addition to the Index.

Principal Investment Risks

Investors should consider the following risk factors and special considerations
associated with investing in the Fund, which may cause you to lose money.

Investment Risk. An investment in the Fund is subject to investment risk,
including the possible loss of the entire principal amount that you invest.

Equity Risk. The value of the equity securities held by the Fund may fall due
to general market and economic conditions, perceptions regarding the industries
in which the issuers of securities held by the Fund participate, or factors
relating to specific companies in which the Fund invests. For example, an
adverse event, such as an unfavorable earnings report, may depress the value of
equity securities of an issuer held by the Fund; the price of common stock of an
issuer may be particularly sensitive to general movements in the stock market;
or a drop in the stock market may depress the price of most or all of the common
stocks and other equity securities held by the Fund. In addition, common stock
of an issuer in the Fund's portfolio may decline in price if the issuer fails to
make anticipated dividend payments because the issuer of the security experiences
a decline in its financial condition. Common stock is subordinated to preferred
stocks, bonds and other debt instruments in a company's capital structure, in
terms of priority to corporate income, and therefore will be subject to greater
dividend risk than preferred stocks or debt instruments of such issuers. In
addition, while broad market measures of common stocks have historically
generated higher average returns than fixed income securities, common stocks
have also experienced significantly more volatility in those returns.

China Investment Risk. Investing in securities of Chinese companies involves
additional risks, including, but not limited to: the economy of China differs,
often unfavorably, from the U.S. economy in such respects as structure, general
development, government involvement, wealth distribution, rate of inflation,
growth rate, allocation of resources and capital reinvestment, among others; the
central government has historically exercised substantial control over virtually
every sector of the Chinese economy through administrative regulation and/or
state ownership; and actions of the Chinese central and local government
authorities continue to have a substantial effect on economic conditions in
China. In addition, previously the Chinese government has from time to time
taken actions that influence the prices at which certain goods may be sold,
encourage companies to invest or concentrate in particular industries, induce
mergers between companies in certain industries and induce private companies to
publicly offer their securities to increase or continue the rate of economic
growth, control the rate of inflation or otherwise regulate economic expansion.
It may do so in the future as well, potentially having a significant adverse
effect on economic conditions in China, the economic prospects for, and the
market prices and liquidity of, the securities of Chinese companies and the
payments of dividends and interest by Chinese companies.

From time to time, certain of the companies comprising the Index that are
located in China may operate in, or have dealings with, countries subject to
sanctions or embargoes imposed by the U.S. government and the United Nations
and/or in countries identified by the U.S. government as state sponsors of
terrorism. One or more of these companies may be subject to constraints under
U.S. law or regulations which could negatively affect the company's performance,
and/or could suffer damage to its reputation if it is identified as a company
which invests or deals with countries which are identified by the U.S. government
as state sponsors of terrorism or subject to sanctions. As an investor in any such
companies, the Fund is indirectly subject to those risks.

Foreign Investment Risk. The Fund's investments in non-U.S. issuers may involve
unique risks compared to investing in securities of U.S. issuers, including less
market liquidity, generally greater market volatility than U.S. securities and
less complete financial information than for U.S. issuers. In addition, adverse
political, economic or social developments could undermine the value of the
Fund's investments or prevent the Fund from realizing the full value of its
investments. Financial reporting standards for companies based in foreign
markets differ from those in the United States. Finally, the value of the
currency of the country in which the Fund has invested could decline relative
to the value of the U.S. dollar, which may affect the value of the investment
to U.S. investors. The Fund will not enter into transactions to hedge against
declines in the value of the Fund's assets that are denominated in a foreign
currency.

Emerging market countries are countries that major international financial
institutions, such as the World Bank, generally consider to be less economically
mature than developed nations. Emerging market countries can include every
nation in the world except the United States, Canada, Japan, Australia, New
Zealand and most countries located in Western Europe. Investing in foreign
countries, particularly emerging market countries, entails the risk that news
and events unique to a country or region will affect those markets and their
issuers. Countries with emerging markets may have relatively unstable governments,
may present the risks of nationalization of businesses, restrictions on foreign
ownership and prohibitions on the repatriation of assets. The economies of emerging
markets countries also may be based on only a few industries, making them more
vulnerable to changes in local or global trade conditions and more sensitive to
debt burdens or inflation rates. Local securities markets may trade a small number
of securities and may be unable to respond effectively to increases in trading volume,
potentially making prompt liquidation of holdings difficult or impossible at times.

Financial Services Sector Risk. The financial services industries are subject
to extensive government regulation, can be subject to relatively rapid change
due to increasingly blurred distinctions between service segments, and can be
significantly affected by availability and cost of capital funds, changes in
interest rates, the rate of corporate and consumer debt defaults, and price
competition. In addition, the deterioration of the credit markets since late
2007 generally has caused an adverse impact in a broad range of markets,
including U.S. and international credit and interbank money markets generally,
thereby affecting a wide range of financial institutions and markets. In
particular, events in the financial sector since late 2008 have resulted,
and may continue to result, in an unusually high degree of volatility in
the financial markets, both domestic and foreign. This situation has created
instability in the financial markets and caused certain financial services
companies to incur large losses. Numerous financial services companies have
experienced substantial declines in the valuations of their assets, taken action
to raise capital (such as the issuance of debt or equity securities), or even
ceased operations. These actions have caused the securities of many financial
services companies to experience a dramatic decline in value. Issuers that have
exposure to the real estate, mortgage and credit markets have been particularly
affected by the foregoing events and the general market turmoil, and it is
uncertain whether or for how long these conditions will continue.

Real Estate Securities and REIT Risk. The Fund invests in companies in the real
estate industry, including REITs. Therefore, the Fund is subject to the risks
associated with investing in real estate, which may include possible declines
in the value of real estate, increased competition and other risks related to
national, state or local real estate conditions, obsolescence of properties,
changes in the availability, cost and terms of mortgage funds (including changes
in interest rates), the impact of changes in environmental laws and possible
environmental liabilities, overbuilding in a real estate company's market,
increases in operating costs and property taxes, changes in zoning laws,
casualty or condemnation losses, regulatory limitations on rent and
fluctuations in rental income.

Certain real estate securities have a relatively small market capitalization,
which may tend to increase the volatility of the market price of these securities.
Real estate securities are dependent upon specialized management skills, have
limited diversification and are, therefore, subject to risks inherent in operating
and financing a limited number of projects. Real estate securities are also subject
to heavy cash flow dependency and defaults by borrowers.

In addition, the federal tax requirement that a REIT distribute substantially
all of its net income to its shareholders may result in a REIT having insufficient
capital for future expenditures. The value of a REIT can depend on the structure
of and cash flow generated by the REIT. In addition, like mutual funds, REITs have
expenses, including advisory and  administration fees, that are paid by their
shareholders. As a result, you will absorb duplicate levels of fees when the
Fund invests in REITs. In addition, REITs are subject to certain provisions
under federal tax law. The failure of a company to qualify as a REIT could
have adverse consequences for the Fund, including significantly reducing
return to the Fund on its investment in any such company.

Limited Exposure Risk. China A-Shares and China B-Shares are not eligible for
inclusion in the Index, even if they would otherwise qualify under the other
criteria set forth under "Index Construction." China A-Shares are subject to
substantial restrictions on foreign investment, while the China B-Share market
generally is smaller and offers less liquidity than the categories of securities
which may be included in the Index. However, by excluding such shares from the
Index, the exposure provided by the Index (and thus the Fund) to the Chinese
presence in the sector may be more limited than would be the case if the Index
included China A-Shares or China B-Shares.

Small and Medium-Sized Company Risk. Investing in securities of small and
medium-sized companies involves greater risk than is customarily associated with
investing in larger, more established companies. These companies' securities may
be more volatile and less liquid than those of larger, more established companies.
These securities may have returns that vary, sometimes significantly, from the
overall stock market.

Micro-Cap Company Risk. Micro-cap stocks involve substantially greater risks of
loss and price fluctuations because their earnings and revenues tend to be less
predictable (and some companies may be experiencing significant losses), and
their share prices tend to be more volatile and their markets less liquid than
companies with larger market capitalizations. Micro-cap companies may be newly
formed or in the early stages of development, with limited product lines, markets
or financial resources and may lack management depth. In addition, there may be
less public information available about these companies. The shares of micro-cap
companies tend to trade less frequently than those of larger, more established
companies, which can adversely affect the pricing of these securities and the
future ability to sell these securities. Also, it may take a long time before
the Fund realizes a gain, if any, on an investment in a micro-cap company.

Non-Correlation Risk. The Fund's return may not match the return of the Index
for a number of reasons. For example, the Fund incurs a number of operating
expenses not applicable to the Index, and incurs costs in buying and selling
securities, especially when rebalancing the Fund's securities holdings to
reflect changes in the composition of the Index.

The Fund may not be fully invested at times, either as a result of cash flows
into the Fund or reserves of cash held by the Fund to meet redemptions and
expenses. If the Fund utilizes a sampling approach, its return may not correlate
as well with the return on the Index, as would be the case if it purchased all
of the securities in the Index with the same weightings as the Index.

Passive Management Risk. Unlike many investment companies, the Fund is not
"actively" managed. Therefore, it would not necessarily sell a security because
the security's issuer was in financial trouble unless that security is removed
from the Index.

Issuer-Specific Changes. The value of an individual security or particular type
of security can be more volatile than the market as a whole and can perform
differently from the value of the market as a whole. The value of securities of
smaller issuers can be more volatile than that of larger issuers.

Non-Diversified Fund Risk. The Fund is considered non-diversified and can invest
a greater portion of assets in securities of individual issuers than a diversified
fund. Even though no single security weight may exceed 5% of the Index at the time
of each annual rebalance, changes in the market value of the Index's constituent
securities may result in the Fund being invested in the securities of individual
issuers (and making additional such investments in the case of creations of
additional Creation Units) in greater proportions. As a result, changes in the
market value of a single investment could cause greater fluctuations in Share
price than would occur in a diversified fund.

The Fund's Shares will change in value, and you could lose money by investing
in the Fund. The Fund may not achieve its investment objective. An investment
in the Fund has not been guaranteed, sponsored, recommended, or approved by the
United States, or any agency, instrumentality or officer of the United States,
has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is
not guaranteed by and is not otherwise an obligation of any bank or insured
depository institution.

Fund Performance

The chart and table below provide some indication of the risks of investing in
the Fund by showing changes in the Fund's performance from year to year and by
showing how the Fund's average annual returns for one year and since inception
compare with those of the Index and a broad measure of market performance. The
Fund's past performance (before and after taxes) is not necessarily an
indication of how the Fund will perform in the future. Updated performance
information for the Fund is available at www.guggenheimfunds.com.

charged by their broker.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Example

This Example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. The Example does not take into account
brokerage commissions that you pay when purchasing or selling Shares of the Fund.

The Example assumes that you invest $10,000 in the Fund for the time periods
indicated and then redeem all of your shares at the end of those periods. The
Example also assumes that your investment has a 5% return each year and that the
Fund's operating expenses remain the same. Although your actual costs may be
higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	Expense Example, with Redemption, 1 Year	Expense Example, with Redemption, 3 Years	Expense Example, with Redemption, 5 Years	Expense Example, with Redemption, 10 Years
Guggenheim Shipping ETF	66	262	474	1,085

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells
securities (or "turns over" its portfolio). A higher portfolio turnover rate may
indicate higher transaction costs and may result in higher taxes when Shares are
held in a taxable account. These costs, which are not reflected in annual fund
operating expenses or in the Example, affect the Fund's performance. During the
most recent fiscal year, the Fund's portfolio turnover rate was 43% of the
average value of its portfolio.

Principal Investment Strategies

The Fund, using a low cost "passive" or "indexing" investment approach, will
seek to replicate, before the Fund's fees and expenses, the performance of the
Index. The Index is designed to measure the performance of high dividend-paying
companies in the shipping industry. CME Group Index Services LLC ("CME Indexes"
or the "Index Provider") uses a rules-based methodology to rank companies by
yield that are involved in the shipping industry globally that primarily
transport goods and materials. The Index Provider determines whether a company
is "high-dividend paying" by ranking it relative to other companies in the
shipping industry based upon indicated annual yield (most recent distribution
annualized and divided by the current share price). The Index Provider considers
a company to be in the shipping industry if its revenues are derived primarily
from shipping activities (excluding companies solely involved in transporting
passengers). As of the date of this Prospectus, a significant percentage (i.e.,
greater than 25%) of the Index was comprised of companies in the industrials
and energy sectors. The companies in the Index may be located in any country,
including those classified as emerging markets. The Index constituents are
weighted based on their float-adjusted market capitalization and, as of August
31, 2012, the market capitalizations of the 25 stocks included in the Index
range from $100 million to $2 billion, which includes micro-, small-, mid- and
large-capitalization stocks as defined by the Index Provider. As of that date,
the Index constituents' countries of domicile were represented (in approximate
market capitalization) in the Index as follows: United States 40.22%, Denmark
18.54%, Japan 12.92%, China 7.28%, Singapore 7.10%, Hong Kong 6.98%, Greece
5.19% and Norway 1.76%.

The Fund will at all times invest at least 90% of its total assets in common
stock, American depositary receipts ("ADRs"), global depositary receipts
("GDRs") and master limited partnerships ("MLPs") that comprise the Index
and the underlying stocks in respect of the ADRs and GDRs in the Index. The
depositary receipts included in the Index may be sponsored or unsponsored. The
Fund has adopted a policy that requires the Fund to provide shareholders with
at least 60 days notice prior to any material change in this policy or the Index.
The Board of Trustees of the Trust may change the Fund's investment strategy and
other policies without shareholder approval, except as otherwise indicated.

The Fund may invest directly in one or more underlying securities represented by
depositary receipts included in the Index under the following limited circumstances:
(a) when market conditions result in the underlying security providing improved
liquidity relative to the depositary receipt; (b) when a depositary receipt is
trading at a significantly different price than its underlying security; or (c)
the timing of trade executions is improved.  

The Investment Adviser seeks a correlation over time of 0.95 or better between the
Fund's performance and the performance of the Index. A figure of 1.00 would represent
perfect correlation.

The Fund generally will invest in all of the securities comprising the Index in
proportion to their weightings in the Index. However, under various circumstances,
it may not be possible or practicable to purchase all of the securities in the Index
in those weightings. In those circumstances, the Fund may purchase a sample of the
securities in the Index in proportions expected by the Investment Adviser to replicate
generally the performance of the Index as a whole. There may also be instances in
which the Investment Adviser may choose to overweight another stock in the Index,
or purchase (or sell) securities not in the Index which the Investment Adviser
believes are appropriate to substitute for one or more Index components, in seeking
to accurately track the Index. In addition, from time to time securities are added
to or removed from the Index. The Fund may sell securities that are represented in
the Index or purchase securities that are not yet represented in the Index in
anticipation of their removal from or addition to the Index.

Prior to July 27, 2011, the Fund sought to replicate, before the Fund's fees and
expenses, the performance of the Delta Global Shipping Index.

Principal Investment Risks

Investors should consider the following risk factors and special considerations
associated with investing in the Fund, which may cause you to lose money.

Investment Risk. An investment in the Fund is subject to investment risk,
including the possible loss of the entire principal amount that you invest.

Equity Risk. The value of the equity securities held by the Fund may fall due to
general market and economic conditions, perceptions regarding the industries in
which the issuers of securities held by the Fund participate, or factors relating
to specific companies in which the Fund invests. For example, an adverse event,
such as an unfavorable earnings report, may depress the value of equity securities
of an issuer held by the Fund; the price of common stock of an issuer may be
particularly sensitive to general movements in the stock market; or a drop in the
stock market may depress the price of most or all of the common stocks and other
equity securities held by the Fund. In addition, common stock of an issuer in the
Fund's portfolio may decline in price if the issuer fails to make anticipated
dividend payments because the issuer of the security experiences a decline in
its financial condition. Common stock is subordinated to preferred stocks, bonds
and other debt instruments in a company's capital structure, in terms of priority
to corporate income, and therefore will be subject to greater dividend risk than
preferred stocks or debt instruments of such issuers. In addition, while broad
market measures of common stocks have historically generated higher average
returns than fixed income securities, common stocks have also experienced
significantly more volatility in those returns.

Shipping Industry Risk. Due to the composition of the Index, the Fund will
concentrate its investments in securities of companies in the shipping industry.
Accordingly, the Fund may be subject to more risks than if it were broadly
diversified over numerous industries and sectors of the economy. Companies in
the shipping industry are subject to volatile fluctuations in the price and
supply of energy fuels, steel, raw materials and other products transported by
containerships. In addition, changes in seaborne transportation patterns,
weather patterns and events including hurricane activity, commodities prices,
international politics and conflicts, port congestion, canal closures, embargoes
and labor strikes can significantly affect companies involved in the maritime
shipping of crude oil, dry bulk and container cargo.

Industrials Sector Risk. The stock prices of companies in the industrials sector
are affected by supply and demand both for their specific product or service and
for industrials sector products in general. The products of manufacturing
companies may face product obsolescence due to rapid technological developments
and frequent new product introduction. Government regulation, world events and
economic conditions may affect the performance of companies in the industrials
sector. Companies in the industrials sector may be at risk for environmental
damage and product liability claims.

Energy Sector Risk. The profitability of companies in the energy sector is
related to worldwide energy prices, exploration, and production spending. Such
companies also are subject to risks of changes in exchange rates, government
regulation, world events, depletion of resources and economic conditions, as
well as market, economic and political risks of the countries where energy
companies are located or do business.

Foreign Investment Risk. The Fund's investments in non-U.S. issuers may involve
unique risks compared to investing in securities of U.S. issuers, including less
market liquidity, generally greater market volatility than U.S. securities and
less complete financial information than for U.S. issuers. In addition, adverse
political, economic or social developments could undermine the value of the
Fund's investments or prevent the Fund from realizing the full value of its
investments. Financial reporting standards for companies based in foreign
markets differ from those in the United States. Finally, the value of the
currency of the country in which the Fund has invested could decline relative
to the value of the U.S. dollar, which may affect the value of the investment
to U.S. investors. The Fund will not enter into transactions to hedge against
declines in the value of the Fund's assets that are denominated in a foreign
currency.

Emerging market countries are countries that major international financial
institutions, such as the World Bank, generally consider to be less economically
mature than developed nations. Emerging market countries can include every
nation in the world except the United States, Canada, Japan, Australia, New
Zealand and most countries located in Western Europe. Investing in foreign
countries, particularly emerging market countries, entails the risk that news
and events unique to a country or region will affect those markets and their
issuers. Countries with emerging markets may have relatively unstable
governments, may present the risks of nationalization of businesses,
restrictions on foreign ownership and prohibitions on the repatriation of
assets. The economies of emerging markets countries also may be based on only a
few industries, making them more vulnerable to changes in local or global trade
conditions and more sensitive to debt burdens or inflation rates.

European Economic Risk. The Economic and Monetary Union of the European Union
(the "EU") requires member countries to comply with restrictions on inflation
rates, deficits, interest rates, debt levels and fiscal and monetary controls,
each of which may significantly affect every country in Europe. Decreasing
imports or exports, changes in governmental or EU regulations on trade, changes
in the exchange rate of the euro, the default or threat of default by an EU
member country on its sovereign debt, and/or an economic recession in an EU
member country may have a significant adverse effect on the economies of EU
member countries and on major trading partners outside Europe. The European
financial markets have recently experienced volatility and have been adversely
affected by concerns about economic downturns, credit rating downgrades, rising
government debt levels and possible default on or restructuring of government
debt in several European countries, including Greece, Ireland, Italy, Portugal
and Spain. A default or debt restructuring by any European country would adversely
impact holders of that country's debt, and sellers of credit default swaps linked
to that country's creditworthiness (which may be located in countries other than
those listed in the previous sentence). These events have adversely affected the
value and exchange rate of the euro and may continue to significantly affect the
economies of every country in Europe, including EU member countries that do not
use the euro and non-EU member countries.

Risks Related to Investing in Japan. The growth of Japan's economy has
historically lagged that of its Asian neighbors and other major developed
economies. The Japanese economy is heavily dependent on international trade
and has been adversely affected by trade tariffs, other protectionist measures,
competition from emerging economies and the economic conditions of its trading
partners. Japan's relations with its neighbors, particularly China, North Korea,
South Korea and Russia, have at times been strained due to territorial disputes,
historical animosities and defense concerns. Most recently, the Japanese government
has shown concern over the increased nuclear and military activity by North Korea.
Strained relations may cause uncertainty in the Japanese markets and adversely
affect the overall Japanese economy in times of crisis. China has become an
important trading partner with Japan, yet the countries' political relationship
has become strained. Should political tension increase, it could adversely affect
the economy, especially the export sector, and destabilize the region as a whole.
Historically, Japan has been subject to unpredictable national politics and may
experience frequent political turnover. Future political developments may lead
to changes in policy that might adversely affect the Fund's investments. In
addition, the Japanese economy faces several concerns, including a financial
system with large levels of nonperforming loans, over-leveraged corporate
balance sheets, extensive cross-ownership by major corporations, a changing
corporate governance structure, and large government deficits. The Japanese
yen has fluctuated widely at times and any increase in its value may cause
a decline in exports that could weaken the economy. Furthermore, Japan has
an aging workforce. It is a labor market undergoing fundamental structural
changes, as traditional lifetime employment clashes with the need for
increased labor mobility, which may adversely affect Japan's economic
competitiveness. Japan also remains heavily dependent on oil imports,
and higher commodity prices could therefore have a negative impact on the
economy. Furthermore, Japanese corporations often engage in high levels of
corporate leveraging, extensive cross-purchases of the securities of other
corporations and are subject to a changing corporate governance structure.

Japan is located in a part of the world that has historically been prone to
natural disasters such as earthquakes, volcanoes and tsunamis and is economically
sensitive to environmental events. In March of 2011 Japan suffered a major
earthquake and tsunami, which resulted in a nuclear crisis and which significantly
impacted the Japanese economy. Japan's economy is still recovering from the impact
of these incidents, and is therfore particularly subject to certain risks as
described above. In particular, the effects of radiation caused by the nuclear
meltdown remain a depressant to farming and agriculture in northern Japan. Japan
remains subject to the risk of additional environmental events or natural disasters.

Small and Medium- Sized Company Risk. Investing in securities of small and
medium-sized companies involves greater risk than is customarily associated with
investing in larger, more established companies. These companies' securities may
be more volatile and less liquid than those of larger, more established companies.
These securities may have returns that vary, sometimes significantly, from the
overall stock market.

Master Limited Partnership Risk. Investments in securities of MLPs involve risks
that differ from an investment in common stock. Holders of the units of MLPs
have more limited control and limited rights to vote on matters affecting the
partnership. There are also certain tax risks associated with an investment in
units of MLPs. In addition, conflicts of interest may exist between common unit
holders, subordinated unit holders and the general partner of a MLP, including a
conflict arising as a result of incentive distribution payments.

Micro-Cap Company Risk. Micro-cap stocks involve substantially greater risks of
loss and price fluctuations because their earnings and revenues tend to be less
predictable (and some companies may be experiencing significant losses), and
their share prices tend to be more volatile and their markets less liquid than
companies with larger market capitalizations. Micro-cap companies may be newly
formed or in the early stages of development, with limited product lines, markets
or financial resources and may lack management depth. In addition, there may be
less public information available abou these companies. The shares of micro-cap
companies tend to trade less frequently than those of larger, more established
companies, which can adversely affect the pricing of these securities and the
future ability to sell these securities. Also, it may take a long time before
the Fund realizes a gain, if any, on an investment in a micro-cap company.

Non-Correlation Risk. The Fund's return may not match the return of the Index
for a number of reasons. For example, the Fund incurs a number of operating
expenses not applicable to the Index, and incurs costs in buying and selling
securities, especially when rebalancing the Fund's securities holdings to
reflect changes in the composition of the Index.

The Fund may not be fully invested at times, either as a result of cash flows
into the Fund or reserves of cash held by the Fund to meet redemptions and
expenses. If the Fund utilizes a sampling approach or otherwise holds
investments other than those that comprise the Index, its return may not
correlate as well with the return on the Index, as would be the case if it
purchased all of the securities in the Index with the same weightings as the
Index.

Passive Management Risk. Unlike many investment companies, the Fund is not
"actively" managed. Therefore, it would not necessarily sell a security because
the security's issuer was in financial trouble unless that security is removed
from the Index.

Issuer-Specific Changes. The value of an individual security or particular type
of security can be more volatile than the market as a whole and can perform
differently from the value of the market as a whole. The value of securities of
smaller issuers can be more volatile than that of larger issuers.

Non-Diversified Fund Risk. The Fund is considered non-diversified and can invest
a greater portion of assets in securities of individual issuers than a diversified
fund. As a result, changes in the market value of a single investment could cause
greater fluctuations in Share price than would occur in a diversified fund.

The Fund's Shares will change in value, and you could lose money by investing in
the Fund. The Fund may not achieve its investment objective. An investment in
the Fund has not been guaranteed, sponsored, recommended, or approved by the
United States, or any agency, instrumentality or officer of the United States,
has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is
not guaranteed by and is not otherwise an obligation of any bank or insured
depository institution.

Fund Performance

The chart and table below provide some indication of the risks of investing in
the Fund by showing changes in the Fund's performance from year to year and by
showing how the Fund's average annual returns for one year and since inception
compare with those of the Index and a broad measure of market performance. The
Fund's past performance (before and after taxes) is not necessarily an
indication of how the Fund will perform in the future. Updated performance
information for the Fund is available at www.guggenheimfunds.com.

Calendar Year Total Return as of 12/31

The Fund commenced operations on June 11, 2010. The Fund's year-to-date total
return was 10.46% as of June 30, 2012.

Guggenheim Canadian Energy Income ETF

Investment Objective

The Fund seeks investment results that correspond generally to the performance,
before the Fund's fees and expenses, of an equity index called the Sustainable
Canadian Energy Income Index (the "Index").

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors purchasing Shares in the secondary
market may be subject to costs (including customary brokerage commissions)
charged by their broker.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		Guggenheim Canadian Energy Income ETF
Management Fees		0.50%
Distribution and service (12b-1) fees	[1]
Other expenses		0.29%
Total annual Fund operating expenses		0.79%
Expense Reimbursements	[2]	0.09%
Total annual Fund operating expenses after Expense Reimbursements		0.70%

Example

This Example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. The Example does not take into account
brokerage commissions that you pay when purchasing or selling Shares of the Fund.

The Example assumes that you invest $10,000 in the Fund for the time periods
indicated and then redeem all of your shares at the end of those periods. The
Example also assumes that your investment has a 5% return each year and that
the Fund's operating expenses remain the same. Although your actual costs may
be higher or lower, based on these assumptions your costs would be:

Guggenheim Canadian Energy Income ETF	72	278	522	1,223

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells
securities (or "turns over" its portfolio). A higher portfolio turnover rate may
indicate higher transaction costs and may result in higher taxes when Shares are
held in a taxable account. These costs, which are not reflected in annual fund
operating expenses or in the Example, affect the Fund's performance. During the
most recent fiscal year, the Fund's portfolio turnover rate was 81% of the
average value of its portfolio.

Principal Investment Strategies

The Fund, using a low cost "passive" or "indexing" investment approach, seeks
to replicate, before the Fund's fees and expenses, the performance of the Index.
As of the date of this prospectus, the Index is comprised of 34 stocks selected,
based on investment and other criteria, from a universe of companies listed on
the Toronto Stock Exchange (the "TSX"), NYSE AMEX, NASDAQ or NYSE. The universe
of companies includes approximately 250 TSX listed oil and gas sector securities
including royalty trusts, as defined by the TSX, and approximately 20 oil sands
resource producers that are classified as oil and gas producers. The companies
in the universe are selected using criteria as identified by Sustainable Wealth
Management, Ltd. ("SWM" or the "Index Provider"). The Fund will invest at least
90% of its total assets in securities that comprise the Index. The Fund has
adopted a policy that requires the Fund to provide shareholders with at least
60 days notice prior to any material change in this policy or the Index. The
Board of Trustees of the Trust may change the Fund's investment strategy and
other policies without shareholder approval, except as otherwise indicated.

The Investment Adviser seeks a correlation over time of 0.95 or better between
the Fund's performance and the performance of the Index. A figure of 1.00 would
represent perfect correlation.

The Fund generally will invest in all of the securities comprising the Index in
proportion to their weightings in the Index. However, under various circumstances,
it may not be possible or practicable to purchase all of the securities in the
Index in those weightings. In those circumstances, the Fund may purchase a sample
of the securities in the Index in proportions expected by the Investment Adviser
to replicate generally the performance of the Index as a whole. There may also be
instances in which the Investment Adviser may choose to overweight another security
in the Index, or purchase (or sell) securities not in the Index which the Investment
Adviser believes are appropriate to substitute for one or more Index components, in
seeking to accurately track the Index. In addition, from time to time securities are
added to or removed from the Index. The Fund may sell securities that  are represented
in the Index or purchase securities that are not yet represented in the Index in
anticipation of their removal from or addition to the Index.

Principal Investment Risks

Investors should consider the following risk factors and special considerations
associated with investing in the Fund, which may cause you to lose money.

Investment Risk. An investment in the Fund is subject to investment risk,
including the possible loss of the entire principal amount that you invest.

Equity Risk. The value of the equity securities held by the Fund may fall due
to general market and economic conditions, perceptions regarding the industries
in which the issuers of securities held by the Fund participate, or factors
relating to specific companies in which the Fund invests. For example, an adverse
event, such as an unfavorable earnings report, may depress the value of equity
securities of an issuer held by the Fund; the price of common stock of an issuer
may be particularly sensitive to general movements in the stock market; or a drop
in the stock market may depress the price of most or all of the common stocks and
other equity securities held by the Fund. In addition, common stock of an issuer
in the Fund's portfolio may decline in price if the issuer fails to make anticipated
dividend payments because the issuer of the security experiences a decline in its
financial condition. Common stock is subordinated to preferred stocks, bonds and
other debt instruments in a company's capital structure, in terms of priority to
corporate income, and therefore will be subject to greater dividend risk than
preferred stocks or debt instruments of such issuers. In addition, while broad
market measures of common stocks have historically generated higher average
returns than fixed income securities, common stocks have also experienced
significantly more volatility in those returns.
  
Oils/Energy Sector Risk. The profitability of companies in the oils/energy
sector is related to worldwide energy prices, exploration, and production
spending. Such companies also are subject to risks of changes in exchange
rates, government regulation, world events, depletion of resources and economic
conditions, as well as market, economic and political risks of the countries
where energy companies are located or do business. Oil and gas exploration and
production can be significantly affected by natural disasters. Oil exploration
and production companies may be adversely affected by changes in exchange rates,
interest rates, government regulation, world events, and economic conditions.
Oil exploration and production companies may be at risk for environmental damage
claims.
  
Foreign Investment Risk. The Fund's investments in non-U.S. issuers may involve
unique risks compared to investing in securities of U.S. issuers, including less
market liquidity, generally greater market volatility than U.S. securities and
less complete financial information than for U.S. issuers. In addition, adverse
political, economic or social developments could undermine the value of the
Fund's investments or prevent the Fund from realizing the full value of its
investments. Financial reporting standards for companies based in foreign
markets differ from those in the United States. Finally, the value of the
currency of the country in which the Fund has invested could decline relative
to the value of the U.S. dollar, which may affect the value of the investment
to U.S. investors. The Fund will not enter into transactions to hedge against
declines in the value of the Fund's assets that are denominated in a foreign
currency.

Canadian Risk. As the Fund invests in Canadian royalty trusts and stocks listed
on the TSX, the Fund is subject to the following risks:

  Commodity Exposure Risk. The Canadian economy is very dependent on the demand
  for, and supply and price of, natural resources. The Canadian market is
  relatively concentrated in issuers involved in the production and distribution
  of natural resources. There is a risk that any changes in these sectors could
  have an adverse impact on the Canadian economy.

  Reliance on Exports Risk. The Canadian economy is dependent on the economies of
  the United States as a key trading partner. Reduction in spending on Canadian
  products and services or changes in the U.S. economy may cause an impact in the
  Canadian economy.

  U.S. Economic Risk. The Canadian economy may be significantly affected by the
  U.S. economy, given that the United States is Canada's largest trading partner
  and foreign investor. Since the implementation of the North American Free Trade
  Agreement (NAFTA) in 1994, total two-way merchandise trade between the United
  States and Canada has more than doubled. To further this relationship, all three
  NAFTA countries entered into The Security and Prosperity Partnership of North
  America in March 2005, which addressed economic and security related issues.
  The new agreement may further affect Canada's dependency on the U.S. economy.

  Structural Risk (Political Risk). In addition, past periodic demands by the
  Province of Quebec for sovereignty have significantly affected equity valuations
  and foreign currency movements in the Canadian market.

Canadian Royalty Trust Risk. As the Fund invests in Canadian royalty trusts, it
is subject to the following risks applicable to Canadian royalty trusts:

  Lack of diversification. The royalty trusts in which the Fund invests are
  heavily invested in oil and gas.

  Potential sacrifice of growth. Potential growth may be sacrificed because
  revenue is passed on to a royalty trust's unit holders (such as the Fund),
  rather than reinvested in the business.

  No guarantees. Royalty trusts generally do not guarantee minimum distributions
  or even return of capital. If the assets underlying a royalty trust do not
  perform as expected, the royalty trust may reduce or even eliminate distributions.
  The declaration of such distributions generally depends upon various factors,
  including the operating performance and financial condition of the royalty
  trust and general economic conditions.

  Potential for tax recharacterization or changes. Under amendments to the Income
  Tax Act (Canada) passed in 2007 (the "SIFT Rules"), certain trusts (defined as
  "SIFT trusts") are taxable on certain income and gains on a basis similar to
  that which applies to a corporation, with the result that tax efficiencies
  formerly available in respect of an investment in the trust may cease to be
  available. A royalty trust may be a SIFT trust. In addition, as a result of the
  SIFT Rules, some trusts may undertake reorganization transactions, the costs of
  which may affect the return earned on an investment in the trust. After any such
  conversion, tax efficiencies that were formerly available in respect of an
  investment in the trust may cease to be available. Accordingly, the SIFT Rules
  have had and may continue to have an effect on the trading price of investments
  in royalty trusts, and consequently could impact the value of Shares of the
  Fund.

Small and Medium-Sized Company Risk. Investing in securities of small and
medium-sized companies involves greater risk than is customarily associated with
investing in larger, more established companies. These companies' securities may
be more volatile and less liquid than those of larger, more established companies.
These securities may have returns that vary, sometimes significantly, from the
overall stock market.

Non-Correlation Risk. The Fund's return may not match the return of the Index
for a number of reasons. For example, the Fund incurs a number of operating
expenses not applicable to the Index, and incurs costs in buying and selling
securities, especially when rebalancing the Fund's securities holdings to
reflect changes in the composition of the Index. Since the Index constituents
may vary on a quarterly basis, the Fund's costs associated with rebalancing may
be greater than those incurred by other exchange-traded funds that track indices
whose composition changes less frequently.

The Fund may not be fully invested at times, either as a result of cash flows
into the Fund or reserves of cash held by the Fund to meet redemptions and
expenses. If the Fund utilizes a sampling approach, its return may not correlate
as well with the return on the Index, as would be the case if it purchased all
of the securities in the Index with the same weightings as the Index.

Passive Management Risk. Unlike many investment companies, the Fund is not
"actively" managed. Therefore, it would not necessarily sell a security because
the security's issuer was in financial trouble unless that security is removed
from the Index.

Issuer-Specific Changes. The value of an individual security or particular type
of security can be more volatile than the market as a whole and can perform
differently from the value of the market as a whole. The value of securities
of smaller issuers can be more volatile than that of larger issuers.

Non-Diversified Fund Risk. The Fund is considered non-diversified and can invest
a greater portion of assets in securities of individual issuers than a diversified
fund. As a result, changes in the market value of a single investment could cause
greater fluctuations in Share price than would occur in a diversified fund.

The Fund's Shares will change in value, and you could lose money by investing
in the Fund. The Fund may not achieve its investment objective. An investment
in the Fund has not been guaranteed, sponsored, recommended, or approved by the
United States, or any agency, instrumentality or officer of the United States,
has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is
not guaranteed by and is not otherwise an obligation of any bank or insured
depository institution.

Fund Performance

The chart and table provide some indication of the risks of investing in the
Fund by showing changes in the Fund's performance from year to year and by
showing how the Fund's average annual returns for one year and since inception
compare with those of the Index and a broad measure of market performance. The
Fund's performance (before and after taxes) is not necessarily an indication of
how the Fund will perform in the future. Updated Fund performance information is
available at www.guggenheimfunds.com.

Calendar Year Total Return as of 12/31

The Fund commenced operations on July 3, 2007. The Fund's year-to-date total
return was -11.66% as of June 30, 2012.

During the periods shown in the chart above, the Fund's highest and lowest
calendar quarter returns were 36.25% and -45.18%, respectively, for the quarters
ended June 30, 2009 and December 31, 2008.

All after-tax returns are calculated using the historical highest individual
federal marginal income tax rates and do not reflect the impact of any state or
local tax. Your own actual after-tax returns will depend on your tax situation
and may differ from what is shown here. After-tax returns are not relevant to
investors who hold Shares of the Fund in tax-deferred accounts such as individual
retirement accounts (IRAs) or employee-sponsored retirement plans.

[1] The Fund has adopted a Distribution and Service (12b-1) Plan pursuant to which the Fund may bear a 12b-1 fee not to exceed 0.25% per annum of the Fund's average daily net assets. However, no such fee is currently paid by the Fund and the Board of Trustees has adopted a resolution that no such fee will be paid for at least 12 months from the date of this prospectus.

[2] The Fund's Investment Adviser has contractually agreed to reimburse Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, a portion of the Fund's licensing fees, offering costs, brokerage commissions and other trading expenses, taxes and extraordinary expenses such as litigation and other expenses not incurred in the ordinary course of the Fund's business) from exceeding 0.65% of average net assets per year (the "Expense Cap"), at least until December 31, 2015, and prior to such date the Investment Adviser may not terminate the arrangement without the approval of the Board of Trustees. For a period of five years subsequent to the Fund's commencement of operations, the Investment Adviser may recover from the Fund expenses reimbursed during the prior three years if the Fund's expense ratio, including the recovered expenses, falls below the Expense Cap. To the extent that the Fund incurs expenses that are excluded from the Expense Cap, the Fund's expense ratio will exceed the Expense Cap.

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund, using a low cost "passive" or "indexing" investment approach, seeks to replicate, before the Fund's fees and expenses, the performance of the Index. As of the date of this prospectus, the Index is comprised of 34 stocks selected, based on investment and other criteria, from a universe of companies listed on the Toronto Stock Exchange (the "TSX"), NYSE AMEX, NASDAQ or NYSE. The universe of companies includes approximately 250 TSX listed oil and gas sector securities including royalty trusts, as defined by the TSX, and approximately 20 oil sands resource producers that are classified as oil and gas producers. The companies in the universe are selected using criteria as identified by Sustainable Wealth Management, Ltd. ("SWM" or the "Index Provider"). The Fund will invest at least 90% of its total assets in securities that comprise the Index. The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Index. The Board of Trustees of the Trust may change the Fund's investment strategy and other policies without shareholder approval, except as otherwise indicated. The Investment Adviser seeks a correlation over time of 0.95 or better between the Fund's performance and the performance of the Index. A figure of 1.00 would represent perfect correlation. The Fund generally will invest in all of the securities comprising the Index in proportion to their weightings in the Index. However, under various circumstances, it may not be possible or practicable to purchase all of the securities in the Index in those weightings. In those circumstances, the Fund may purchase a sample of the securities in the Index in proportions expected by the Investment Adviser to replicate generally the performance of the Index as a whole. There may also be instances in which the Investment Adviser may choose to overweight another security in the Index, or purchase (or sell) securities not in the Index which the Investment Adviser believes are appropriate to substitute for one or more Index components, in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that  are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index.

Risk [Heading]	rr_RiskHeading	Principal Investment Risks
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	Investors should consider the following risk factors and special considerations associated with investing in the Fund, which may cause you to lose money. Investment Risk. An investment in the Fund is subject to investment risk, including the possible loss of the entire principal amount that you invest. Equity Risk. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by the Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund. In addition, common stock of an issuer in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns.    Oils/Energy Sector Risk. The profitability of companies in the oils/energy sector is related to worldwide energy prices, exploration, and production spending. Such companies also are subject to risks of changes in exchange rates, government regulation, world events, depletion of resources and economic conditions, as well as market, economic and political risks of the countries where energy companies are located or do business. Oil and gas exploration and production can be significantly affected by natural disasters. Oil exploration and production companies may be adversely affected by changes in exchange rates, interest rates, government regulation, world events, and economic conditions. Oil exploration and production companies may be at risk for environmental damage claims.    Foreign Investment Risk. The Fund's investments in non-U.S. issuers may involve unique risks compared to investing in securities of U.S. issuers, including less market liquidity, generally greater market volatility than U.S. securities and less complete financial information than for U.S. issuers. In addition, adverse political, economic or social developments could undermine the value of the Fund's investments or prevent the Fund from realizing the full value of its investments. Financial reporting standards for companies based in foreign markets differ from those in the United States. Finally, the value of the currency of the country in which the Fund has invested could decline relative to the value of the U.S. dollar, which may affect the value of the investment to U.S. investors. The Fund will not enter into transactions to hedge against declines in the value of the Fund's assets that are denominated in a foreign currency. Canadian Risk. As the Fund invests in Canadian royalty trusts and stocks listed on the TSX, the Fund is subject to the following risks:   Commodity Exposure Risk. The Canadian economy is very dependent on the demand   for, and supply and price of, natural resources. The Canadian market is   relatively concentrated in issuers involved in the production and distribution   of natural resources. There is a risk that any changes in these sectors could   have an adverse impact on the Canadian economy.   Reliance on Exports Risk. The Canadian economy is dependent on the economies of   the United States as a key trading partner. Reduction in spending on Canadian   products and services or changes in the U.S. economy may cause an impact in the   Canadian economy.   U.S. Economic Risk. The Canadian economy may be significantly affected by the   U.S. economy, given that the United States is Canada's largest trading partner   and foreign investor. Since the implementation of the North American Free Trade   Agreement (NAFTA) in 1994, total two-way merchandise trade between the United   States and Canada has more than doubled. To further this relationship, all three   NAFTA countries entered into The Security and Prosperity Partnership of North   America in March 2005, which addressed economic and security related issues.   The new agreement may further affect Canada's dependency on the U.S. economy.   Structural Risk (Political Risk). In addition, past periodic demands by the   Province of Quebec for sovereignty have significantly affected equity valuations   and foreign currency movements in the Canadian market. Canadian Royalty Trust Risk. As the Fund invests in Canadian royalty trusts, it is subject to the following risks applicable to Canadian royalty trusts:   Lack of diversification. The royalty trusts in which the Fund invests are   heavily invested in oil and gas.   Potential sacrifice of growth. Potential growth may be sacrificed because   revenue is passed on to a royalty trust's unit holders (such as the Fund),   rather than reinvested in the business.   No guarantees. Royalty trusts generally do not guarantee minimum distributions   or even return of capital. If the assets underlying a royalty trust do not   perform as expected, the royalty trust may reduce or even eliminate distributions.   The declaration of such distributions generally depends upon various factors,   including the operating performance and financial condition of the royalty   trust and general economic conditions.   Potential for tax recharacterization or changes. Under amendments to the Income   Tax Act (Canada) passed in 2007 (the "SIFT Rules"), certain trusts (defined as   "SIFT trusts") are taxable on certain income and gains on a basis similar to   that which applies to a corporation, with the result that tax efficiencies   formerly available in respect of an investment in the trust may cease to be   available. A royalty trust may be a SIFT trust. In addition, as a result of the   SIFT Rules, some trusts may undertake reorganization transactions, the costs of   which may affect the return earned on an investment in the trust. After any such   conversion, tax efficiencies that were formerly available in respect of an   investment in the trust may cease to be available. Accordingly, the SIFT Rules   have had and may continue to have an effect on the trading price of investments   in royalty trusts, and consequently could impact the value of Shares of the   Fund. Small and Medium-Sized Company Risk. Investing in securities of small and medium-sized companies involves greater risk than is customarily associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of larger, more established companies. These securities may have returns that vary, sometimes significantly, from the overall stock market. Non-Correlation Risk. The Fund's return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Index. Since the Index constituents may vary on a quarterly basis, the Fund's costs associated with rebalancing may be greater than those incurred by other exchange-traded funds that track indices whose composition changes less frequently. The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. If the Fund utilizes a sampling approach, its return may not correlate as well with the return on the Index, as would be the case if it purchased all of the securities in the Index with the same weightings as the Index. Passive Management Risk. Unlike many investment companies, the Fund is not "actively" managed. Therefore, it would not necessarily sell a security because the security's issuer was in financial trouble unless that security is removed from the Index. Issuer-Specific Changes. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than that of larger issuers. Non-Diversified Fund Risk. The Fund is considered non-diversified and can invest a greater portion of assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. The Fund's Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund has not been guaranteed, sponsored, recommended, or approved by the United States, or any agency, instrumentality or officer of the United States, has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is not guaranteed by and is not otherwise an obligation of any bank or insured depository institution.

Strategy [Heading]	rr_StrategyHeading	Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund, using a low cost "passive" or "indexing" investment approach, seeks to replicate, before the Fund's fees and expenses, the performance of the Index. The Index is designed to measure and monitor the performance of publicly-traded mainland China-based small capitalization companies. For inclusion in the Index, AlphaShares, LLC ("AlphaShares" or the "Index Provider") defines small-capitalization companies as those companies with a maximum $1.5 billion float-adjusted market capitalization. The Index may include Hong Kong listed securities, including China H-shares and Red Chips. China H-shares are issued by companies incorporated in mainland China and listed on the Hong Kong Stock Exchange. Red Chip shares are issued by companies with controlling Chinese shareholders that are incorporated outside mainland China and listed on the Hong Kong Stock Exchange. The Index may also include N-Shares, which are issued by companies based in mainland China and listed on the NYSE Arca or NASDAQ. The Index will not include China A-Shares (which are subject to substantial restrictions on foreign investment) or China B-Shares (which offer a generally smaller market and limited liquidity), each of which trade on the Shanghai Stock Exchange and the Shenzhen Stock Exchange. The Fund will invest at least 90% of its total assets in common stock, American depositary receipts ("ADRs"), American depositary shares ("ADSs"), global depositary receipts ("GDRs") and international depositary receipts ("IDRs") that comprise the Index and depositary receipts representing common stocks included in the Index (or underlying securities representing the ADRs, ADSs, GDRs and IDRs included in the Index). The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Index. The Board of Trustees of the Trust may change the Fund's investment strategy and other policies without shareholder approval, except as otherwise indicated. The Fund may invest directly in one or more underlying securities represented by the ADRs included in the Index under the following limited circumstances: (a) when market conditions result in the underlying security providing more liquidity than the ADR; (b) when an ADR is trading at a significantly different price than its underlying security; or (c) the timing of trade execution is improved due to the local market in which an underlying security is traded being open at different times than the market in which the security's corresponding ADR is traded. The Investment Adviser seeks a correlation over time of 0.95 or better between the Fund's performance and the performance of the Index. A figure of 1.00 would represent perfect correlation. The Fund generally will invest in all of the securities comprising the Index in proportion to their weightings in the Index. However, under various circumstances, it may not be possible or practicable to purchase all of the securities in the Index in those weightings. In those circumstances, the Fund may purchase a sample of the securities in the Index in proportions expected by the Investment Adviser to replicate generally the performance of the Index as a whole. There may also be instances in which the Investment Adviser may choose to overweight another security in the Index, or purchase (or sell) securities not in the Index which the Investment Adviser believes are appropriate to substitute for one or more Index components, in seeking to accurately track the Index. In addition, from time to time securities are added to or removed from the Index. The Fund may sell securities that are represented in the Index or purchase securities that are not yet represented in the Index in anticipation of their removal from or addition to the Index.

Risk [Heading]	rr_RiskHeading	Principal Investment Risks
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	Investors should consider the following risk factors and special considerations associated with investing in the Fund, which may cause you to lose money. Investment Risk. An investment in the Fund is subject to investment risk, including the possible loss of the entire principal amount that you invest. China Investment Risk. Investing in securities of Chinese companies involves additional risks, including, but not limited to: the economy of China differs, often unfavorably, from the U.S. economy in such respects as structure, general development, government involvement, wealth distribution, rate of inflation, growth rate, allocation of resources and capital reinvestment, among others; the central government has historically exercised substantial control over virtually every sector of the Chinese economy through administrative regulation and/or state ownership; and actions of the Chinese central and local government authorities continue to have a substantial effect on economic conditions in China. In addition, previously the Chinese government has from time to time taken actions that influence the prices at which certain goods may be sold, encourage companies to invest or concentrate in particular industries, induce mergers between companies in certain industries and induce private companies to publicly offer their securities to increase or continue the rate of economic growth, control the rate of inflation or otherwise regulate economic expansion. It may do so in the future as well, potentially having a significant adverse effect on economic conditions in China, the economic prospects for, and the market prices and liquidity of, the securities of Chinese companies and the payments of dividends and interest by Chinese companies. From time to time, certain of the companies comprising the Index that are located in China may operate in, or have dealings with, countries subject to sanctions or embargoes imposed by the U.S. government and the United Nations and/or in countries identified by the U.S. government as state sponsors of terrorism. One or more of these companies may be subject to constraints under U.S. law or regulations which could negatively affect the company's performance, and/or could suffer damage to its reputation if it is identified as a company which invests or deals with countries which are identified by the U.S. government as state sponsors of terrorism or subject to sanctions. As an investor in such companies, the Fund is indirectly subject to those risks. Equity Risk. The value of the equity securities held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or factors relating to specific companies in which the Fund invests. For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by the Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund. In addition, common stock of an issuer in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns. Foreign Investment Risk. The Fund's investments in non-U.S. issuers may involve unique risks compared to investing in securities of U.S. issuers, including less market liquidity, generally greater market volatility than U.S. securities and less complete financial information than for U.S. issuers. In addition, adverse political, economic or social developments could undermine the value of the Fund's investments or prevent the Fund from realizing the full value of its investments. Financial reporting standards for companies based in foreign markets differ from those in the United States. Finally, the value of the currency of the country in which the Fund has invested could decline relative to the value of the U.S. dollar, which may affect the value of the investment to U.S. investors. The Fund will not enter into transactions to hedge against declines in the value of the Fund's assets that are denominated in a foreign currency. Emerging market countries are countries that major international financial institutions, such as the World Bank, generally consider to be less economically mature than developed nations. Emerging market countries can include every nation in the world except the United States, Canada, Japan, Australia, New Zealand and most countries located in Western Europe. Investing in foreign countries, particularly emerging market countries, entails the risk that news and events unique to a country or region will affect those  markets and their issuers. Countries with emerging markets may have relatively unstable governments, may present the risks of nationalization of businesses, restrictions on foreign ownership and prohibitions on the repatriation of assets. The economies of emerging markets countries also may be based on only a few industries, making them more vulnerable to changes in local or global trade conditions and more sensitive to debt burdens or inflation rates. Local securities markets may trade a small number of securities and may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of holdings difficult or impossible at times. Financial Services Sector Risk. The financial services industries are subject to extensive government regulation, can be subject to relatively rapid change due to increasingly blurred distinctions between service segments, and can be significantly affected by availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, and price competition. In addition, the deterioration of the credit markets since late 2007 generally has caused an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. In particular, events in the financial sector since late 2008 have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. This situation has created instability in the financial markets and caused certain financial services companies to incur large losses. Numerous financial services companies have experienced substantial declines in the valuations of their assets, taken action to raise capital (such as the issuance of debt or equity securities), or even ceased operations. These actions have caused the securities of many financial services companies to experience a dramatic decline in value. Issuers that have exposure to the real estate, mortgage and credit markets have been particularly affected by the foregoing events and the general market turmoil, and it is uncertain whether or for how long these conditions will continue. Industrial Sector Risk. The stock prices of companies in the industrial sector are affected by supply and demand both for their specific product or service and for industrial sector products in general. The products of manufacturing companies may face product obsolescence due to rapid technological developments and frequent new product introduction. Government regulation, world events and economic conditions may affect the performance of companies in the industrial sector. Companies in the industrial sector may be at risk for environmental damage and product liability claims. Limited Exposure Risk. China A-Shares and China B-Shares are not eligible for inclusion in the Index, even if they would otherwise qualify under the other criteria set forth under "Index Construction." China A-Shares are subject to substantial restrictions on foreign investment, while the China B-Share market generally is smaller and offers less liquidity than the categories of securities which may be included in the Index. However, by excluding such shares from the Index, the exposure provided by the Index (and thus the Fund) to the Chinese presence in the applicable sector may be more limited than would be the case if the Index included China A-Shares or China B-Shares. Small Company Risk. Investing in securities of small companies involves greater risk than is customarily associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of larger, more established companies. These securities may have returns that vary, sometimes significantly, from the overall stock market. Micro-cap Company Risk. Micro-cap stocks involve substantially greater risks of loss and price fluctuations because their earnings and revenues tend to be less predictable (and some companies may be experiencing significant losses), and their share prices tend to be more volatile and their markets less liquid than companies with larger market capitalizations. Micro-cap companies may be newly formed or in the early stages of development, with limited product lines, markets or financial resources and may lack management depth. In addition, there may be less public information available about these companies. The shares of micro-cap companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the future ability to sell these securities. Also, it may take a long time before the Fund realizes a gain, if any, on an investment in a micro-cap company. Non-Correlation Risk. The Fund's return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Index. The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. If the Fund utilizes a sampling approach, its return may not correlate as well with the return on the Index, as would be the case if it purchased all of the securities in the Index with the same weightings as the Index. Passive Management Risk. Unlike many investment companies, the Fund is not "actively" managed. Therefore, it would not necessarily sell a security because the security's issuer was in financial trouble unless that security is removed from the Index. Issuer-Specific Changes. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than that of larger issuers. Non-Diversified Fund Risk. The Fund is considered non-diversified and can invest a greater portion of assets in securities of individual issuers than a diversified fund. Even though no single security weight may exceed 5% of the Index at the time of each annual rebalance, changes in the market value of the Index's constituent securities may result in the Fund being invested in the securities of individual issuers (and making additional such investments in the case of creations of additional Creation Units) in greater proportions. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. The Fund's Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund has not been guaranteed, sponsored, recommended, or approved by the United States, or any agency, instrumentality or officer of the United States, has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is not guaranteed by and is not otherwise an obligation of any bank or insured depository institution.

[1] The Fund has adopted a Distribution and Service (12b-1) Plan pursuant to which the Fund may bear a 12b-1 fee not to exceed 0.25% per annum of the Fund's average daily net assets. However, no such fee is currently paid by the Fund and the Board of Trustees has adopted a resolution that no such fee will be paid for at least 12 months from the date of this prospectus.

[2] The Fund's Investment Adviser has contractually agreed to reimburse Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, a portion of the Fund's licensing fees, offering costs up to 0.25% of average net assets, brokerage commissions and other trading expenses, taxes and extraordinary expenses such as litigation and other expenses not incurred in the ordinary course of the Fund's business) from exceeding 0.70% of average net assets per year (the "Expense Cap"), at least until December 31, 2015, and prior to such date the Investment Adviser may not terminate the arrangement without the approval of the Board of Trustees. For a period of five years subsequent to the Fund's commencement of operations, the Investment Adviser may recover from the Fund expenses reimbursed during the prior three years if the Fund's expense ratio, including the recovered expenses, falls below the Expense Cap. To the extent that the Fund incurs expenses that are excluded from the Expense Cap, the Fund's expense ratio will exceed the Expense Cap.

The Index is designed to measure and monitor the performance of the investable universe of publicly-traded companies and real estate investment trusts ("REITs") deriving a majority of their revenues from real estate development, management and/or ownership of property in China or the Special Administrative Regions of China, which are Hong Kong and Macau. The Index was created by AlphaShares, LLC ("AlphaShares" or the "Index Provider") and is maintained by Standard & Poor's (the "Index Administrator"). The Index includes equity securities of companies of all categories of market capitalizations, as defined by AlphaShares (subject to the minimum capitalization requirements set forth below under "Index Construction"). The Index may include Hong Kong listed securities, including China H-shares and Red Chips. China H-shares are issued by companies incorporated in mainland China and listed on the Hong Kong Stock Exchange. Red Chip shares are issued by companies with controlling Chinese shareholders that are incorporated outside mainland China and listed on the Hong Kong Stock Exchange. The Index may also include N-Shares, which are issued by companies based in mainland China and listed on the NYSE Arca or NASDAQ. The Index will not include China A-Shares (which are subject to substantial restrictions on foreign investment) or China B-Shares (which offer a generally smaller market and limited liquidity), each of which trade on the Shanghai Stock Exchange and the Shenzhen Stock Exchange. The Fund will invest at least 90% of its total assets in common stocks, American depositary receipts ("ADRs"), American depositary shares ("ADSs"), global depositary receipts ("GDRs") and international depositary receipts ("IDRs") that comprise the Index and depositary  receipts representing common stocks included in the Index (or underlying securities representing the ADRs, ADSs, GDRs and IDRs included in the Index). The Fund has adopted a policy that requires the Fund to provide shareholders with at least 60 days notice prior to any material change in this policy or the Index. The Board of Trustees of the Trust may change the Fund's investment strategy and other policies without shareholder approval, except as otherwise indicated. The Fund may invest directly in one or more underlying securities represented by the ADRs included in the Index under the following limited circumstances: (a) when market conditions result in the underlying security providing more liquidity than the ADR; (b) when an ADR is trading at a significantly different price than its underlying security; or (c) the timing of trade execution is improved due to the local market in which an underlying security is traded being open at different times than the market in which the security's corresponding ADR is traded. The Investment Adviser seeks a correlation over time of 0.95 or better between the Fund's performance and the performance of the Index. A figure of 1.00 would represent perfect correlation. The Fund generally will invest in all of the securities comprising the Index in proportion to their weightings in the Index. However, under various circumstances, it may not be possible or practicable to purchase all of the securities in the Index in those weightings. In those circumstances, the Fund may purchase a sample of the securities in the Index in proportions expected by the Investment Adviser to replicate generally the performance of the Index as a whole.

For example, an adverse event, such as an unfavorable earnings report, may depress the value of equity securities of an issuer held by the Fund; the price of common stock of an issuer may be particularly sensitive to general movements in the stock market; or a drop in the stock market may depress the price of most or all of the common stocks and other equity securities held by the Fund. In addition, common stock of an issuer in the Fund's portfolio may decline in price if the issuer fails to make anticipated dividend payments because the issuer of the security experiences a decline in its financial condition. Common stock is subordinated to preferred stocks, bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stocks or debt instruments of such issuers. In addition, while broad market measures of common stocks have historically generated higher average returns than fixed income securities, common stocks have also experienced significantly more volatility in those returns. China Investment Risk. Investing in securities of Chinese companies involves additional risks, including, but not limited to: the economy of China differs, often unfavorably, from the U.S. economy in such respects as structure, general development, government involvement, wealth distribution, rate of inflation, growth rate, allocation of resources and capital reinvestment, among others; the central government has historically exercised substantial control over virtually every sector of the Chinese economy through administrative regulation and/or state ownership; and actions of the Chinese central and local government authorities continue to have a substantial effect on economic conditions in China. In addition, previously the Chinese government has from time to time taken actions that influence the prices at which certain goods may be sold, encourage companies to invest or concentrate in particular industries, induce mergers between companies in certain industries and induce private companies to publicly offer their securities to increase or continue the rate of economic growth, control the rate of inflation or otherwise regulate economic expansion. It may do so in the future as well, potentially having a significant adverse effect on economic conditions in China, the economic prospects for, and the market prices and liquidity of, the securities of Chinese companies and the payments of dividends and interest by Chinese companies. From time to time, certain of the companies comprising the Index that are located in China may operate in, or have dealings with, countries subject to sanctions or embargoes imposed by the U.S. government and the United Nations and/or in countries identified by the U.S. government as state sponsors of terrorism. One or more of these companies may be subject to constraints under U.S. law or regulations which could negatively affect the company's performance, and/or could suffer damage to its reputation if it is identified as a company which invests or deals with countries which are identified by the U.S. government as state sponsors of terrorism or subject to sanctions. As an investor in any such companies, the Fund is indirectly subject to those risks. Foreign Investment Risk. The Fund's investments in non-U.S. issuers may involve unique risks compared to investing in securities of U.S. issuers, including less market liquidity, generally greater market volatility than U.S. securities and less complete financial information than for U.S. issuers. In addition, adverse political, economic or social developments could undermine the value of the Fund's investments or prevent the Fund from realizing the full value of its investments. Financial reporting standards for companies based in foreign markets differ from those in the United States. Finally, the value of the currency of the country in which the Fund has invested could decline relative to the value of the U.S. dollar, which may affect the value of the investment to U.S. investors. The Fund will not enter into transactions to hedge against declines in the value of the Fund's assets that are denominated in a foreign currency. Emerging market countries are countries that major international financial institutions, such as the World Bank, generally consider to be less economically mature than developed nations. Emerging market countries can include every nation in the world except the United States, Canada, Japan, Australia, New Zealand and most countries located in Western Europe. Investing in foreign countries, particularly emerging market countries, entails the risk that news and events unique to a country or region will affect those markets and their issuers. Countries with emerging markets may have relatively unstable governments, may present the risks of nationalization of businesses, restrictions on foreign ownership and prohibitions on the repatriation of assets. The economies of emerging markets countries also may be based on only a few industries, making them more vulnerable to changes in local or global trade conditions and more sensitive to debt burdens or inflation rates. Local securities markets may trade a small number of securities and may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of holdings difficult or impossible at times. Financial Services Sector Risk. The financial services industries are subject to extensive government regulation, can be subject to relatively rapid change due to increasingly blurred distinctions between service segments, and can be significantly affected by availability and cost of capital funds, changes in interest rates, the rate of corporate and consumer debt defaults, and price competition. In addition, the deterioration of the credit markets since late 2007 generally has caused an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. In particular, events in the financial sector since late 2008 have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign. This situation has created instability in the financial markets and caused certain financial services companies to incur large losses. Numerous financial services companies have experienced substantial declines in the valuations of their assets, taken action to raise capital (such as the issuance of debt or equity securities), or even ceased operations. These actions have caused the securities of many financial services companies to experience a dramatic decline in value. Issuers that have exposure to the real estate, mortgage and credit markets have been particularly affected by the foregoing events and the general market turmoil, and it is uncertain whether or for how long these conditions will continue. Real Estate Securities and REIT Risk. The Fund invests in companies in the real estate industry, including REITs. Therefore, the Fund is subject to the risks associated with investing in real estate, which may include possible declines in the value of real estate, increased competition and other risks related to national, state or local real estate conditions, obsolescence of properties, changes in the availability, cost and terms of mortgage funds (including changes in interest rates), the impact of changes in environmental laws and possible environmental liabilities, overbuilding in a real estate company's market, increases in operating costs and property taxes, changes in zoning laws, casualty or condemnation losses, regulatory limitations on rent and fluctuations in rental income. Certain real estate securities have a relatively small market capitalization, which may tend to increase the volatility of the market price of these securities. Real estate securities are dependent upon specialized management skills, have limited diversification and are, therefore, subject to risks inherent in operating and financing a limited number of projects. Real estate securities are also subject to heavy cash flow dependency and defaults by borrowers. In addition, the federal tax requirement that a REIT distribute substantially all of its net income to its shareholders may result in a REIT having insufficient capital for future expenditures. The value of a REIT can depend on the structure of and cash flow generated by the REIT. In addition, like mutual funds, REITs have expenses, including advisory and  administration fees, that are paid by their shareholders. As a result, you will absorb duplicate levels of fees when the Fund invests in REITs. In addition, REITs are subject to certain provisions under federal tax law. The failure of a company to qualify as a REIT could have adverse consequences for the Fund, including significantly reducing return to the Fund on its investment in any such company. Limited Exposure Risk. China A-Shares and China B-Shares are not eligible for inclusion in the Index, even if they would otherwise qualify under the other criteria set forth under "Index Construction." China A-Shares are subject to substantial restrictions on foreign investment, while the China B-Share market generally is smaller and offers less liquidity than the categories of securities which may be included in the Index. However, by excluding such shares from the Index, the exposure provided by the Index (and thus the Fund) to the Chinese presence in the sector may be more limited than would be the case if the Index included China A-Shares or China B-Shares. Small and Medium-Sized Company Risk. Investing in securities of small and medium-sized companies involves greater risk than is customarily associated with investing in larger, more established companies. These companies' securities may be more volatile and less liquid than those of larger, more established companies. These securities may have returns that vary, sometimes significantly, from the overall stock market. Micro-Cap Company Risk. Micro-cap stocks involve substantially greater risks of loss and price fluctuations because their earnings and revenues tend to be less predictable (and some companies may be experiencing significant losses), and their share prices tend to be more volatile and their markets less liquid than companies with larger market capitalizations. Micro-cap companies may be newly formed or in the early stages of development, with limited product lines, markets or financial resources and may lack management depth. In addition, there may be less public information available about these companies. The shares of micro-cap companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the future ability to sell these securities. Also, it may take a long time before the Fund realizes a gain, if any, on an investment in a micro-cap company. Non-Correlation Risk. The Fund's return may not match the return of the Index for a number of reasons. For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the composition of the Index. The Fund may not be fully invested at times, either as a result of cash flows into the Fund or reserves of cash held by the Fund to meet redemptions and expenses. If the Fund utilizes a sampling approach, its return may not correlate as well with the return on the Index, as would be the case if it purchased all of the securities in the Index with the same weightings as the Index. Passive Management Risk. Unlike many investment companies, the Fund is not "actively" managed. Therefore, it would not necessarily sell a security because the security's issuer was in financial trouble unless that security is removed from the Index. Issuer-Specific Changes. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of securities of smaller issuers can be more volatile than that of larger issuers. Non-Diversified Fund Risk. The Fund is considered non-diversified and can invest a greater portion of assets in securities of individual issuers than a diversified fund. Even though no single security weight may exceed 5% of the Index at the time of each annual rebalance, changes in the market value of the Index's constituent securities may result in the Fund being invested in the securities of individual issuers (and making additional such investments in the case of creations of additional Creation Units) in greater proportions. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. The Fund's Shares will change in value, and you could lose money by investing in the Fund. The Fund may not achieve its investment objective. An investment in the Fund has not been guaranteed, sponsored, recommended, or approved by the United States, or any agency, instrumentality or officer of the United States, has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is not guaranteed by and is not otherwise an obligation of any bank or insured depository institution.

[1] The Fund has adopted a Distribution and Service (12b-1) Plan pursuant to which the Fund may bear a 12b-1 fee not to exceed 0.25% per annum of the Fund's average daily net assets. However, no such fee is currently paid by the Fund and the Board of Trustees has adopted a resolution that no such fee will be paid for at least 12 months from the date of this prospectus.

[2] The Fund's Investment Adviser has contractually agreed to reimburse Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, a portion of the Fund's licensing fees, offering costs up to 0.25% of average net assets, brokerage commissions and other trading expenses, taxes and extraordinary expenses such as litigation and other expenses not incurred in the ordinary course of the Fund's business) from exceeding 0.65% of average net assets per year (the "Expense Cap"), at least until December 31, 2015, and prior to such date the Investment Adviser may not terminate the arrangement without the approval of the Board of Trustees. For a period of five years subsequent to the Fund's commencement of operations, the Investment Adviser may recover from the Fund expenses reimbursed during the prior three years if the Fund's expense ratio, including the recovered expenses, falls below the Expense Cap. To the extent that the Fund incurs expenses that are excluded from the Expense Cap, the Fund's expense ratio will exceed the Expense Cap.

Guggenheim China Small Cap ETF (Prospectus Summary) | Guggenheim China Small Cap ETF

Guggenheim China Small Cap ETF

Investment Objective

The Fund seeks investment results that correspond generally to the performance,
before the Fund's fees and expenses, of an equity index called the AlphaShares
China Small Cap Index (the "Index").

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors purchasing Shares in the secondary
market may be subject to costs (including customary brokerage commissions)
charged by their broker.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		Guggenheim China Small Cap ETF
Management Fees		0.55%
Distribution and service (12b-1) fees	[1]
Other expenses		0.37%
Total annual Fund operating expenses		0.92%
Expense Reimbursements	[2]	0.17%
Total annual Fund operating expenses after Expense Reimbursements		0.75%

Example

This Example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. The Example does not take into account
brokerage commissions that you pay when purchasing or selling Shares of the Fund.

The Example assumes that you invest $10,000 in the Fund for the time periods
indicated and then redeem all of your shares at the end of those periods. The
Example also assumes that your investment has a 5% return each year and that the
Fund's operating expenses remain the same. Although your actual costs may be
higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	Expense Example, with Redemption, 1 Year	Expense Example, with Redemption, 3 Years	Expense Example, with Redemption, 5 Years	Expense Example, with Redemption, 10 Years
Guggenheim China Small Cap ETF	77	294	568	1,350

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells
securities (or "turns over" its portfolio). A higher portfolio turnover rate may
indicate higher transaction costs and may result in higher taxes when Shares are
held in a taxable account. These costs, which are not reflected in annual fund
operating expenses or in the Example, affect the Fund's performance. During the
most recent fiscal year, the Fund's portfolio turnover rate was 35% of the
average value of its portfolio.

Principal Investment Strategies

The Fund, using a low cost "passive" or "indexing" investment approach, seeks to
replicate, before the Fund's fees and expenses, the performance of the Index.
The Index is designed to measure and monitor the performance of publicly-traded
mainland China-based small capitalization companies. For inclusion in the Index,
AlphaShares, LLC ("AlphaShares" or the "Index Provider") defines
small-capitalization companies as those companies with a maximum $1.5 billion
float-adjusted market capitalization.

The Index may include Hong Kong listed securities, including China H-shares and
Red Chips. China H-shares are issued by companies incorporated in mainland China
and listed on the Hong Kong Stock Exchange. Red Chip shares are issued by
companies with controlling Chinese shareholders that are incorporated outside
mainland China and listed on the Hong Kong Stock Exchange. The Index may also
include N-Shares, which are issued by companies based in mainland China and
listed on the NYSE Arca or NASDAQ. The Index will not include China A-Shares
(which are subject to substantial restrictions on foreign investment) or China
B-Shares (which offer a generally smaller market and limited liquidity), each
of which trade on the Shanghai Stock Exchange and the Shenzhen Stock Exchange.

The Fund will invest at least 90% of its total assets in common stock, American
depositary receipts ("ADRs"), American depositary shares ("ADSs"), global
depositary receipts ("GDRs") and international depositary receipts ("IDRs") that
comprise the Index and depositary receipts representing common stocks included
in the Index (or underlying securities representing the ADRs, ADSs, GDRs and
IDRs included in the Index). The Fund has adopted a policy that requires the
Fund to provide shareholders with at least 60 days notice prior to any material
change in this policy or the Index. The Board of Trustees of the Trust may
change the Fund's investment strategy and other policies without shareholder
approval, except as otherwise indicated.

The Fund may invest directly in one or more underlying securities represented by
the ADRs included in the Index under the following limited circumstances: (a)
when market conditions result in the underlying security providing more liquidity
than the ADR; (b) when an ADR is trading at a significantly different price than
its underlying security; or (c) the timing of trade execution is improved due to
the local market in which an underlying security is traded being open at different
times than the market in which the security's corresponding ADR is traded.

The Investment Adviser seeks a correlation over time of 0.95 or better between
the Fund's performance and the performance of the Index. A figure of 1.00 would
represent perfect correlation.

The Fund generally will invest in all of the securities comprising the Index in
proportion to their weightings in the Index. However, under various circumstances,
it may not be possible or practicable to purchase all of the securities in the
Index in those weightings. In those circumstances, the Fund may purchase a sample
of the securities in the Index in proportions expected by the Investment Adviser
to replicate generally the performance of the Index as a whole. There may also be
instances in which the Investment Adviser may choose to overweight another security
in the Index, or purchase (or sell) securities not in the Index which the Investment
Adviser believes are appropriate to substitute for one or more Index components, in
seeking to accurately track the Index. In addition, from time to time securities are
added to or removed from the Index. The Fund may sell securities that are represented
in the Index or purchase securities that are not yet represented in the Index in
anticipation of their removal from or addition to the Index.

Principal Investment Risks

Investors should consider the following risk factors and special considerations
associated with investing in the Fund, which may cause you to lose money.

Investment Risk. An investment in the Fund is subject to investment risk,
including the possible loss of the entire principal amount that you invest.

China Investment Risk. Investing in securities of Chinese companies involves
additional risks, including, but not limited to: the economy of China differs,
often unfavorably, from the U.S. economy in such respects as structure, general
development, government involvement, wealth distribution, rate of inflation,
growth rate, allocation of resources and capital reinvestment, among others; the
central government has historically exercised substantial control over virtually
every sector of the Chinese economy through administrative regulation and/or
state ownership; and actions of the Chinese central and local government
authorities continue to have a substantial effect on economic conditions in
China. In addition, previously the Chinese government has from time to time
taken actions that influence the prices at which certain goods may be sold,
encourage companies to invest or concentrate in particular industries, induce
mergers between companies in certain industries and induce private companies to
publicly offer their securities to increase or continue the rate of economic
growth, control the rate of inflation or otherwise regulate economic expansion.
It may do so in the future as well, potentially having a significant adverse
effect on economic conditions in China, the economic prospects for, and the
market prices and liquidity of, the securities of Chinese companies and the
payments of dividends and interest by Chinese companies.

From time to time, certain of the companies comprising the Index that are
located in China may operate in, or have dealings with, countries subject to
sanctions or embargoes imposed by the U.S. government and the United Nations
and/or in countries identified by the U.S. government as state sponsors of
terrorism. One or more of these companies may be subject to constraints under
U.S. law or regulations which could negatively affect the company's performance,
and/or could suffer damage to its reputation if it is identified as a company
which invests or deals with countries which are identified by the U.S.
government as state sponsors of terrorism or subject to sanctions. As an
investor in such companies, the Fund is indirectly subject to those risks.

Equity Risk. The value of the equity securities held by the Fund may fall due to
general market and economic conditions, perceptions regarding the industries in
which the issuers of securities held by the Fund participate, or factors relating
to specific companies in which the Fund invests. For example, an adverse event,
such as an unfavorable earnings report, may depress the value of equity securities
of an issuer held by the Fund; the price of common stock of an issuer may be
particularly sensitive to general movements in the stock market; or a drop in
the stock market may depress the price of most or all of the common stocks and
other equity securities held by the Fund. In addition, common stock of an issuer
in the Fund's portfolio may decline in price if the issuer fails to make anticipated
dividend payments because the issuer of the security experiences a decline in its
financial condition. Common stock is subordinated to preferred stocks, bonds and
other debt instruments in a company's capital structure, in terms of priority to
corporate income, and therefore will be subject to greater dividend risk than
preferred stocks or debt instruments of such issuers. In addition, while broad
market measures of common stocks have historically generated higher average
returns than fixed income securities, common stocks have also experienced
significantly more volatility in those returns.

Foreign Investment Risk. The Fund's investments in non-U.S. issuers may involve
unique risks compared to investing in securities of U.S. issuers, including less
market liquidity, generally greater market volatility than U.S. securities and
less complete financial information than for U.S. issuers. In addition, adverse
political, economic or social developments could undermine the value of the
Fund's investments or prevent the Fund from realizing the full value of its
investments. Financial reporting standards for companies based in foreign
markets differ from those in the United States. Finally, the value of the
currency of the country in which the Fund has invested could decline relative
to the value of the U.S. dollar, which may affect the value of the investment
to U.S. investors. The Fund will not enter into transactions to hedge against
declines in the value of the Fund's assets that are denominated in a foreign
currency.

Emerging market countries are countries that major international financial
institutions, such as the World Bank, generally consider to be less economically
mature than developed nations. Emerging market countries can include every
nation in the world except the United States, Canada, Japan, Australia, New
Zealand and most countries located in Western Europe. Investing in foreign
countries, particularly emerging market countries, entails the risk that news
and events unique to a country or region will affect those  markets and their
issuers. Countries with emerging markets may have relatively unstable governments,
may present the risks of nationalization of businesses, restrictions on foreign
ownership and prohibitions on the repatriation of assets. The economies of emerging
markets countries also may be based on only a few industries, making them more
vulnerable to changes in local or global trade conditions and more sensitive to
debt burdens or inflation rates. Local securities markets may trade a small number
of securities and may be unable to respond effectively to increases in trading
volume, potentially making prompt liquidation of holdings difficult or impossible
at times.

Financial Services Sector Risk. The financial services industries are subject
to extensive government regulation, can be subject to relatively rapid change
due to increasingly blurred distinctions between service segments, and can be
significantly affected by availability and cost of capital funds, changes in
interest rates, the rate of corporate and consumer debt defaults, and price
competition. In addition, the deterioration of the credit markets since late
2007 generally has caused an adverse impact in a broad range of markets,
including U.S. and international credit and interbank money markets generally,
thereby affecting a wide range of financial institutions and markets. In
particular, events in the financial sector since late 2008 have resulted,
and may continue to result, in an unusually high degree of volatility in
the financial markets, both domestic and foreign. This situation has created
instability in the financial markets and caused certain financial services
companies to incur large losses. Numerous financial services companies have
experienced substantial declines in the valuations of their assets, taken action
to raise capital (such as the issuance of debt or equity securities), or even
ceased operations. These actions have caused the securities of many financial
services companies to experience a dramatic decline in value. Issuers that have
exposure to the real estate, mortgage and credit markets have been particularly
affected by the foregoing events and the general market turmoil, and it is
uncertain whether or for how long these conditions will continue.

Industrial Sector Risk. The stock prices of companies in the industrial sector
are affected by supply and demand both for their specific product or service and
for industrial sector products in general. The products of manufacturing companies
may face product obsolescence due to rapid technological developments and frequent
new product introduction. Government regulation, world events and economic
conditions may affect the performance of companies in the industrial sector.
Companies in the industrial sector may be at risk for environmental damage and
product liability claims.

Limited Exposure Risk. China A-Shares and China B-Shares are not eligible for
inclusion in the Index, even if they would otherwise qualify under the other
criteria set forth under "Index Construction." China A-Shares are subject to
substantial restrictions on foreign investment, while the China B-Share market
generally is smaller and offers less liquidity than the categories of securities
which may be included in the Index. However, by excluding such shares from the
Index, the exposure provided by the Index (and thus the Fund) to the Chinese
presence in the applicable sector may be more limited than would be the case if
the Index included China A-Shares or China B-Shares.

Small Company Risk. Investing in securities of small companies involves greater
risk than is customarily associated with investing in larger, more established
companies. These companies' securities may be more volatile and less liquid than
those of larger, more established companies. These securities may have returns
that vary, sometimes significantly, from the overall stock market.

Micro-cap Company Risk. Micro-cap stocks involve substantially greater risks of
loss and price fluctuations because their earnings and revenues tend to be less
predictable (and some companies may be experiencing significant losses), and
their share prices tend to be more volatile and their markets less liquid than
companies with larger market capitalizations. Micro-cap companies may be newly
formed or in the early stages of development, with limited product lines, markets
or financial resources and may lack management depth. In addition, there may be
less public information available about these companies. The shares of micro-cap
companies tend to trade less frequently than those of larger, more established
companies, which can adversely affect the pricing of these securities and the
future ability to sell these securities. Also, it may take a long time before
the Fund realizes a gain, if any, on an investment in a micro-cap company.

Non-Correlation Risk. The Fund's return may not match the return of the Index
for a number of reasons. For example, the Fund incurs a number of operating
expenses not applicable to the Index, and incurs costs in buying and selling
securities, especially when rebalancing the Fund's securities holdings to
reflect changes in the composition of the Index.

The Fund may not be fully invested at times, either as a result of cash flows
into the Fund or reserves of cash held by the Fund to meet redemptions and
expenses. If the Fund utilizes a sampling approach, its return may not correlate
as well with the return on the Index, as would be the case if it purchased all
of the securities in the Index with the same weightings as the Index.

Passive Management Risk. Unlike many investment companies, the Fund is not
"actively" managed. Therefore, it would not necessarily sell a security because
the security's issuer was in financial trouble unless that security is removed
from the Index.

Issuer-Specific Changes. The value of an individual security or particular type
of security can be more volatile than the market as a whole and can perform
differently from the value of the market as a whole. The value of securities of
smaller issuers can be more volatile than that of larger issuers.

Non-Diversified Fund Risk. The Fund is considered non-diversified and can invest
a greater portion of assets in securities of individual issuers than a diversified
fund. Even though no single security weight may exceed 5% of the Index at the time
of each annual rebalance, changes in the market value of the Index's constituent
securities may result in the Fund being invested in the securities of individual
issuers (and making additional such investments in the case of creations of
additional Creation Units) in greater proportions. As a result, changes in the
market value of a single investment could cause greater fluctuations in Share
price than would occur in a diversified fund.

The Fund's Shares will change in value, and you could lose money by investing in
the Fund. The Fund may not achieve its investment objective. An investment in
the Fund has not been guaranteed, sponsored, recommended, or approved by the
United States, or any agency, instrumentality or officer of the United States,
has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is
not guaranteed by and is not otherwise an obligation of any bank or insured
depository institution.

Fund Performance

The chart and table below provide some indication of the risks of investing in
the Fund by showing changes in the Fund's performance from year to year and by
showing how the Fund's average annual returns for one year and since inception
compare with those of the Index and a broad measure of market performance. The
Fund's past performance (before and after taxes) is not necessarily an
indication of how the Fund will perform in the future. Updated performance
information for the Fund is available at www.guggenheimfunds.com.

Calendar Year Total Return as of 12/31

The Fund commenced operations on January 30, 2008. The Fund's year-to-date
return was 0.98% as of June 30, 2012.

During the periods shown in the chart above, the Fund's highest and lowest
calendar quarter returns were 52.30% and -33.69%, respectively, for the quarters

[1] The Fund has adopted a Distribution and Service (12b-1) Plan pursuant to which the Fund may bear a 12b-1 fee not to exceed 0.25% per annum of the Fund's average daily net assets. However, no such fee is currently paid by the Fund and the Board of Trustees has adopted a resolution that no such fee will be paid for at least 12 months from the date of this prospectus.

[2] The Fund's Investment Adviser has contractually agreed to reimburse Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, a portion of the Fund's licensing fees, offering costs up to 0.25% of average net assets, brokerage commissions and other trading expenses, taxes and extraordinary expenses such as litigation and other expenses not incurred in the ordinary course of the Fund's business) from exceeding 0.70% of average net assets per year (the "Expense Cap"), at least until December 31, 2015, and prior to such date the Investment Adviser may not terminate the arrangement without the approval of the Board of Trustees. For a period of five years subsequent to the Fund's commencement of operations, the Investment Adviser may recover from the Fund expenses reimbursed during the prior three years if the Fund's expense ratio, including the recovered expenses, falls below the Expense Cap. To the extent that the Fund incurs expenses that are excluded from the Expense Cap, the Fund's expense ratio will exceed the Expense Cap.

Guggenheim International Multi-Asset Income ETF (Prospectus Summary) | Guggenheim International Multi-Asset Income ETF

Guggenheim International Multi-Asset Income ETF

Investment Objective

The Fund seeks investment results that correspond generally to the performance,
before the Fund's fees and expenses, of an index called the Zacks International
Multi-Asset Income Index (the "Index")

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares").

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		Guggenheim International Multi-Asset Income ETF
Management Fees		0.50%
Distribution and service (12b-1) fees	[1]
Other expenses		0.42%
Acquired Fund Fees and Expenses	[2]	0.14%
Total annual Fund operating expenses		1.06%
Expense Reimbursements	[3]	0.22%
Total annual Fund operating expenses after Expense Reimbursements		0.84%

Example

This Example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. The Example does not take into account
brokerage commissions that you pay when purchasing or selling Shares of the Fund.

The Example assumes that you invest $10,000 in the Fund for the time periods
indicated and then redeem all of your shares at the end of those periods. The
Example also assumes that your investment has a 5% return each year and that the
Fund's operating expenses remain the same. Although your actual costs may be
higher or lower, based on these assumptions your costs would be:

Expense Example (USD $)	Expense Example, with Redemption, 1 Year	Expense Example, with Redemption, 3 Years	Expense Example, with Redemption, 5 Years	Expense Example, with Redemption, 10 Years
Guggenheim International Multi-Asset Income ETF	86	322	627	1,496

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells
securities (or "turns over" its portfolio). A higher portfolio turnover rate may
indicate higher transaction costs and may result in higher taxes when Shares are
held in a taxable account. These costs, which are not reflected in annual fund
operating expenses or in the Example, affect the Fund's performance. During the
most recent fiscal year ended May 31, 2012, the Fund's portfolio turnover rate
was 73% of the average value of its portfolio.

Principal Investment Strategies

The Fund, using a low cost "passive" or "indexing" investment approach, seeks
to replicate, before the Fund's fees and expenses, the performance of the Index.
The Index is comprised of approximately 150 stocks selected, based on investment
and other criteria, from a universe of international companies, global REITs,
master limited partnerships ("MLPs"), Canadian royalty trusts, American
depositary receipts ("ADRs") of emerging market companies and U.S. listed
closed-end funds that invest in international companies, and at all times is
comprised of at least 40% non-U.S. securities. The companies in the universe are
selected using a proprietary strategy developed by Zacks Investment Research,
Inc. ("Zacks" or the "Index Provider"). The Fund will invest at least 90% of its
total assets in stocks that comprise the Index (and underlying securities
representing the ADRs included in the Index). The Fund has adopted a policy that
requires the Fund to provide shareholders with at least 60 days notice prior to
any material change in this policy or the Index. The Board of Trustees of the
Trust may change the Fund's investment strategy and other policies without
shareholder approval, except as otherwise indicated.

The Investment Adviser seeks a correlation over time of 0.95 or better between
the Fund's performance and the performance of the Index. A figure of 1.00 would
represent perfect correlation.

The Fund generally will invest in all of the securities comprising the Index in
proportion to their weightings in the Index. However, under various circumstances,
it may not be possible or practicable to purchase all of the securities in the
Index in those weightings. In those circumstances, the Fund may purchase a sample
of the securities in the Index in proportions expected by the Investment Adviser
to replicate generally the performance of the Index as a whole. There may also be
instances in which  the Investment Adviser may choose to overweight another
security in the Index, or purchase (or sell) securities not in the Index which the
Investment Adviser believes are appropriate to substitute for one or more Index
components, in seeking to accurately track the Index. In addition, from time to
time securities are added to or removed from the Index. The Fund may sell securities
that are represented in the Index or purchase securities that are not yet represented
in the Index in anticipation of their removal from or addition to the Index.

The Fund may invest directly in one or more underlying securities represented by
the ADRs included in the Index under the following limited circumstances: (a)
when market conditions result in the underlying security providing more liquidity
than the ADR; (b) when an ADR is trading at a significantly different price than
its underlying security; or (c) the timing of trade execution is improved due to
the local market in which an underlying security is traded being open at different
times than the market in which the security's corresponding ADR is traded.

Principal Investment Risks

Investors should consider the following risk factors and special considerations
associated with investing in the Fund, which may cause you to lose money.

Investment Risk. An investment in the Fund is subject to investment risk,
including the possible loss of the entire principal amount that you invest.

Equity Risk. The value of the equity securities held by the Fund may fall due
to general market and economic conditions, perceptions regarding the industries
in which the issuers of securities held by the Fund participate, or factors
relating to specific companies in which the Fund invests. For example, an
adverse event, such as an unfavorable earnings report, may depress the value of
equity securities of an issuer held by the Fund; the price of common stock of an
issuer may be particularly sensitive to general movements in the stock market;
or a drop in the stock market may depress the price of most or all of the common
stocks and other equity securities held by the Fund. In addition, common stock
of an issuer in the Fund's portfolio may decline in price if the issuer fails to
make anticipated dividend payments because the issuer of the security experiences
a decline in its financial condition. Common stock is subordinated to preferred
stocks, bonds and other debt instruments in a company's capital structure, in
terms of priority to corporate income, and therefore will be subject to greater
dividend risk than preferred stocks or debt instruments of such issuers. In
addition, while broad market measures of common stocks have historically generated
higher average returns than fixed income securities, common stocks have also
experienced significantly more volatility in those returns.

Foreign Investment Risk. The Fund's investments in non-U.S. issuers may involve
unique risks compared to investing in securities of U.S. issuers, including less
market liquidity, generally greater market volatility than U.S. securities and
less complete financial information than for U.S. issuers. In addition, adverse
political, economic or social developments could undermine the value of the
Fund's investments or prevent the Fund from realizing the full value of its
investments. Financial reporting standards for companies based in foreign
markets differ from those in the United States. Finally, the value of the
currency of the country in which the Fund has invested could decline relative
to the value of the U.S. dollar, which may affect the value of the investment
to U.S. investors. The Fund will not enter into transactions to hedge against
declines in the value of the Fund's assets that are denominated in a foreign
currency.

Emerging market countries are countries that major international financial
institutions, such as the World Bank, generally consider to be less economically
mature than developed nations. Emerging market countries can include every
nation in the world except the United States, Canada, Japan, Australia, New
Zealand and most countries located in Western Europe. Investing in foreign
countries, particularly emerging market countries, entails the risk that news
and events unique to a country or region will affect those markets and their
issuers. Countries with emerging markets may have relatively unstable governments,
may present the risks of nationalization of businesses, restrictions on foreign
ownership and prohibitions on the repatriation of assets. The economies of emerging
markets countries also may be based on only a few industries, making them more
vulnerable to changes in local or global trade conditions and more sensitive to
debt burdens or inflation rates. Local securities markets may trade a small number
of securities and may be unable to respond effectively to increases in trading
volume, potentially making prompt liquidation of holdings difficult or impossible
at times.

European Economic Risk. The Economic and Monetary Union of the European Union
(the "EU") requires member countries to comply with restrictions on inflation
rates, deficits, interest rates, debt levels and fiscal and monetary controls,
each of which may significantly affect every country in Europe. Decreasing
imports or exports, changes in governmental or EU regulations on trade, changes
in the exchange rate of the euro, the default or threat of default by an EU
member country on its sovereign debt, and/or an economic recession in an EU
member country may have a significant adverse effect on the economies of EU
member countries and on major trading partners outside Europe. The European
financial markets have recently experienced volatility and have been adversely
affected by concerns about economic downturns, credit rating downgrades, rising
government debt levels and possible default on or restructuring of government
debt in several European countries, including Greece, Ireland, Italy, Portugal
and Spain. A default or debt restructuring by any European country would
adversely impact holders of that country's debt, and sellers of credit default
swaps linked to that country's creditworthiness (which may be located in
countries other than those listed in the previous sentence). These events have
adversely affected the value and exchange rate of the euro and may continue to
significantly affect the economies of every country in Europe, including EU
member countries that do not use the euro and non-EU member countries.

Financial Services Sector Risk. The financial services industries are subject
to extensive government regulation, can be subject to relatively rapid change
due to increasingly blurred distinctions between service segments, and can be
significantly affected by availability and cost of capital funds, changes in
interest rates, the rate of corporate and consumer debt defaults, and price
competition. In addition, the deterioration of the credit markets since late
2007 generally has caused an adverse impact in a broad range of markets,
including U.S. and international credit and interbank money markets generally,
thereby affecting a wide range of financial institutions and markets. In
particular, events in the financial sector since late 2008 have resulted,
and may continue to result, in an unusually high degree of volatility in
the financial markets, both domestic and foreign. This situation has created
instability in the financial markets and caused certain financial services
companies to incur large losses. Numerous financial services companies have
experienced substantial declines in the valuations of their assets, taken
action to raise capital (such as the issuance of debt or equity securities),
or even ceased operations. These actions have caused the securities of many
financial services companies to experience a dramatic decline in value. Issuers
that have exposure to the real estate, mortgage and credit markets have been
particularly affected by the foregoing events and the general market turmoil,
and it is uncertain whether or for how long these conditions will continue.

Canadian Risk. As the Fund invests in Canadian royalty trusts and stocks listed
on the Toronto Stock Exchange, the Fund is subject to the following risks:

  Commodity Exposure Risk. The Canadian economy is very dependent on the demand
  for, and supply and price of, natural resources. The Canadian market is
  relatively concentrated in issuers involved in the production and distribution
  of natural resources. There is a risk that any changes in these sectors could
  have an adverse impact on the Canadian economy.

  Reliance on Exports Risk. The Canadian economy is dependent on the economies of
  the United States as a key trading partner. Reduction in spending on Canadian
  products and services or changes in the U.S. economy may cause an impact in the
  Canadian economy.

  U.S. Economic Risk. The Canadian economy may be significantly affected by the
  U.S. economy, given that the United States is Canada's largest trading partner
  and foreign investor. Since the implementation of the North American Free Trade
  Agreement (NAFTA) in 1994, total two-way merchandise trade between the United
  States and Canada has more than doubled. To further this relationship, all three
  NAFTA countries entered into The Security and Prosperity Partnership of North
  America in March 2005, which addressed economic and security related issues.
  The new agreement may further affect Canada's dependency on the U.S. economy.

  Structural Risk (Political Risk). In addition, past periodic demands by the
  Province of Quebec for sovereignty have significantly affected equity valuations
  and foreign currency movements in the Canadian market.

Canadian Royalty Trust Risk. As the Fund invests in Canadian royalty trusts,
it is subject to the following risks applicable to Canadian royalty trusts:

  Lack of diversification. The royalty trusts in which the Fund invests are
  heavily invested in oil and gas.

  Potential sacrifice of growth. Potential growth may be sacrificed because
  revenue is passed on to a royalty trust's unit holders (such as the Fund),
  rather than reinvested in the business.

  No guarantees. Royalty trusts generally do not guarantee minimum distributions
  or even return of capital. If the assets underlying a royalty trust do not
  perform as expected, the royalty trust may reduce or even eliminate distributions.
  The declaration of such distributions generally depends upon various factors,
  including the operating performance and financial condition of the royalty trust
  and general economic conditions.

  Potential for tax recharacterization or changes. Under amendments to the Income
  Tax Act (Canada) passed in 2007 (the "SIFT Rules"), certain trusts (defined as
  "SIFT trusts") are taxable on certain income and gains on a basis similar to that
  which applies to a corporation, with the result that tax efficiencies formerly
  available in respect of an investment in the trust may cease to be available. A
  royalty trust may be a SIFT trust. In addition, as a result of the SIFT Rules,
  some trusts may undertake reorganization transactions, the costs of which may
  affect the return earned on an investment in the trust. After any such conversion,
  tax efficiencies that were formerly available in respect of an investment in the
  trust may cease to be available. Accordingly, the SIFT Rules have had and may
  continue to have an effect on the trading price of investments in royalty trusts,
  and consequently could impact the value of Shares of the Fund.

REIT Risk. The risks of investing in real estate companies include, among
others, adverse changes in national, state or local real estate conditions;
obsolescence of properties; changes in the availability, cost and terms of
mortgage funds; and the impact of changes in environmental laws. In addition,
the federal tax requirement that a REIT distribute substantially all of its net
income to its shareholders may result in a REIT having insufficient capital for
future expenditures. The value of a REIT can depend on the structure of and cash
flow generated by the REIT. In addition, like mutual funds, REITs have expenses,
including advisory and administration fees, that are paid by their shareholders.
As a result, you will absorb duplicate levels of fees when the Fund invests in
REITs. In addition, REITs are subject to certain provisions under federal tax
law. The failure of a company to qualify as a REIT could have adverse consequences
for the Fund, including significantly reducing return to the Fund on its investment
in such company.

Master Limited Partnership Risk. Investments in securities of MLPs involve risks
that differ from an investment in common stock. Holders of the units of MLPs
have more limited control and limited rights to vote on matters affecting the
partnership. There are also certain tax risks associated with an investment in
units of MLPs. In addition, conflicts of interest may exist between common unit
holders, subordinated unit holders and the general partner of a MLP, including a
conflict arising as a result of incentive distribution payments.

Risks of Investing in Other Investment Companies. Shares of other investment
companies are subject to the management fees and other expenses of those companies,
and the purchase of shares of some investment companies (in the case of closed-end
investment companies) may sometimes require the payment of substantial premiums
above the value of such companies' portfolio securities or net asset values. The
Fund must continue, at the same time, to pay its own management fees and expenses
with respect to all of its investments, including shares of other investment
companies. The securities of other investment companies may also be leveraged
and will therefore be subject to certain leverage risks.

Small and Medium-Sized Company Risk. Investing in securities of small and
medium-sized companies involves greater risk than is customarily associated with
investing in larger, more established companies. These companies' securities may
be more volatile and less liquid than those of larger, more established companies.
These securities may have returns that vary, sometimes significantly, from the
overall stock market.

Non-Correlation Risk. The Fund's return may not match the return of the Index
for a number of reasons. For example, the Fund incurs a number of operating
expenses not applicable to the Index, and incurs costs in buying and selling
securities, especially when rebalancing the Fund's securities holdings to
reflect changes in the composition of the Index. Since the Index constituents
may vary on a semi-annual basis, the Fund's costs associated with  rebalancing
may be greater than those incurred by other exchange-traded funds that track
indices whose composition changes less frequently.

The Fund may not be fully invested at times, either as a result of cash flows
into the Fund or reserves of cash held by the Fund to meet redemptions and
expenses. If the Fund utilizes a sampling approach, its return may not correlate
as well with the return on the Index, as would be the case if it purchased all
of the securities in the Index with the same weightings as the Index.

Passive Management Risk. Unlike many investment companies, the Fund is not
"actively" managed. Therefore, it would not necessarily sell a security because
the security's issuer was in financial trouble unless that security is removed
from the Index.

Issuer-Specific Changes. The value of an individual security or particular type
of security can be more volatile than the market as a whole and can perform
differently from the value of the market as a whole. The value of securities of
smaller issuers can be more volatile than that of larger issuers.

Non-Diversified Fund Risk. The Fund is considered non-diversified and can invest
a greater portion of assets in securities of individual issuers than a diversified
fund. As a result, changes in the market value of a single investment could cause
greater fluctuations in Share price than would occur in a diversified fund.

The Fund's Shares will change in value, and you could lose money by investing
in the Fund. The Fund may not achieve its investment objective. An investment
in the Fund has not been guaranteed, sponsored, recommended, or approved by the
United States, or any agency, instrumentality or officer of the United States,
has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is
not guaranteed by and is not otherwise an obligation of any bank or insured
depository institution.

Fund Performance

Calendar Year Total Return as of 12/31

The Fund commenced operations on July 11, 2007. The Fund's year-to-date total
return was -0.88% as of June 30, 2012.

During the periods shown in the chart above, the Fund's highest and lowest
calendar quarter returns were 33.97% and -24.82%, respectively, for the quarters

brokerage commissions that you pay when purchasing or selling Shares of the Fund.

The Example assumes that you invest $10,000 in the Fund for the time periods
indicated and then redeem all of your shares at the end of those periods. The
Example also assumes that your investment has a 5% return each year and that the
Fund's operating expenses remain the same. Although your actual costs may be higher
or lower, based on these assumptions your costs would be:

Expense Example (USD $)	Expense Example, with Redemption, 1 Year	Expense Example, with Redemption, 3 Years	Expense Example, with Redemption, 5 Years	Expense Example, with Redemption, 10 Years
Guggenheim Timber ETF	72	278	529	1,249

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells
securities (or "turns over" its portfolio). A higher portfolio turnover rate may
indicate higher transaction costs and may result in higher taxes when Shares are
held in a taxable account. These costs, which are not reflected in annual fund
operating expenses or in the Example, affect the Fund's performance. During the
most recent fiscal year, the Fund's portfolio turnover rate was 56% of the
average value of its portfolio.

Principal Investment Strategies

The Fund, using a low cost "passive" or "indexing" investment approach, seeks
to replicate, before the Fund's fees and expenses, the performance of the Index.
All securities in the Index are selected from the universe of global timber
companies. Beacon Indexes LLC ("Beacon" or the "Index Provider") defines global
timber companies as firms who own or lease forested land and harvest the timber
from such forested land for commercial use and sale of wood-based products,
including lumber, pulp or other processed or finished goods such as paper and
packaging. Potential Index constituents include securities with market
capitalizations greater than $300 million, which includes securities of all
categories of market capitalizations, as determined by Beacon. The Fund will
invest at least 90% of its total assets in common stock, American depositary
receipts ("ADRs") and global depositary receipts ("GDRs") that comprise the
Index and depositary receipts representing common stocks included in the Index
(or underlying securities representing the ADRs and GDRs included in the Index).
The Fund has adopted a policy that requires the Fund to provide shareholders
with at least 60 days notice prior to any material change in this policy or the
Index. The Board of Trustees of the Trust may change the Fund's investment
strategy and other policies without shareholder approval, except as otherwise
indicated.

The Fund may invest directly in one or more underlying securities represented by
the ADRs included in the Index under the following limited circumstances: (a)
when market conditions result in the underlying security providing more liquidity
than the ADR; (b) when an ADR is trading at a significantly different price than
its underlying security; or (c) the timing of trade execution is improved due to
the local market in which an underlying security is traded being open at different
times than the market in which the security's corresponding ADR is traded.

The Investment Adviser seeks a correlation over time of 0.95 or better between
the Fund's performance and the performance of the Index. A figure of 1.00 would
represent perfect correlation.

The Fund generally will invest in all of the securities comprising the Index in
proportion to their weightings in the Index. However, under various circumstances,
it may not be possible or practicable to purchase all of the securities in the
Index in those weightings. In those circumstances, the Fund may purchase a sample
of the securities in the Index in proportions expected by the Investment Adviser
to replicate generally the performance of the Index as a whole. There may also
be instances in which the Investment Adviser may choose to overweight another
security in the Index, or purchase (or sell) securities not in the Index which
the Investment Adviser believes are appropriate to substitute for one or more
Index components, in seeking to accurately track the Index. In addition, from
time to time securities are added to or removed from the Index. The Fund may
sell securities that are represented in the Index or purchase securities that
are not yet represented in the Index in anticipation of their removal from or
addition to the Index.

Principal Investment Risks

Investors should consider the following risk factors and special considerations
associated with investing in the Fund, which may cause you to lose money.

Investment Risk. An investment in the Fund is subject to investment risk,
including the possible loss of the entire principal amount that you invest.

Equity Risk. The value of the equity securities held by the Fund may fall due to
general market and economic conditions, perceptions regarding the industries in
which the issuers of securities held by the Fund participate, or factors relating
to specific companies in which the Fund invests. For example, an adverse event,
such as an unfavorable earnings report, may depress the value of equity securities
of an issuer held by the Fund; the price of common stock of an issuer may be
particularly sensitive to general movements in the stock market; or a drop in the
stock market may depress the price of most or all of the common stocks and other
equity securities held by the Fund. In addition, common stock of an issuer in the
Fund's portfolio may decline in price if the issuer fails to make anticipated
dividend payments because the issuer of the security experiences a decline in
its financial condition. Common stock is subordinated to preferred stocks, bonds
and other debt instruments in a company's capital structure, in terms of priority
to corporate income, and therefore will be subject to greater dividend risk than
preferred stocks or debt instruments of such issuers. In addition, while broad
market measures of common stocks have historically generated higher average
returns than fixed income securities, common stocks have also experienced
significantly more volatility in those returns.

Global Timber Industry Risk. As the Index is comprised of issuers in the global
timber industry, the Fund is therefore focused in that industry. Accordingly,
the Fund may be subject to more risks than if it were broadly diversified over
numerous industries and sectors of the economy. The market value of securities
of global timber companies may be affected by numerous factors, including events
occurring in nature and international politics. For example, the volume and
value of timber that can be harvested from timberlands may be limited by natural
disasters and other events such as fire, volcanic eruptions, insect infestation,
disease, ice storms, wind storms, flooding, other weather conditions and other
causes. In periods of poor logging conditions, global timber companies may
harvest less timber than expected. Global timber companies involved in the
forest, paper and packaging products industries are highly competitive globally,
including significant competition from non-wood and engineered wood products,
and no single company is dominant. These industries have suffered, and continue
to suffer, from excess capacity. Global timber companies are subject to many
federal, state and local environmental, health and safety laws and regulations,
particularly with respect to the restoration and reforestation of timberlands,
harvesting timber near waterways, discharges of pollutants and emissions, and the
management, disposal and remediation of hazardous substances or other contaminants.
Political risks and the other risks to which foreign securities are subject may
also affect domestic companies in which the Fund may invest if they have significant
operations or investments in foreign countries. In particular, tariffs, quotas or
trade agreements can also affect the markets for products of global timber companies,
particularly wood products. In addition, rising interest rates and general economic
conditions may affect the demand for timber products.

Foreign Investment Risk. The Fund's investments in non-U.S. issuers may involve
unique risks compared to investing in securities of U.S. issuers, including less
market liquidity, generally greater market volatility than U.S. securities and
less complete financial information than for U.S. issuers. In addition, adverse
political, economic or social developments could undermine the value of the
Fund's investments or prevent the Fund from realizing the full value of its
investments. Financial reporting standards for companies based in foreign
markets differ from those in the United States. Finally, the value of the
currency of the country in which the Fund has invested could decline relative
to the value of the U.S. dollar, which may affect the value of the investment
to U.S. investors. The Fund will not enter into transactions to hedge against
declines in the value of the Fund's assets that are denominated in a foreign
currency.

Emerging market countries are countries that major international financial
institutions, such as the World Bank, generally consider to be less economically
mature than developed nations. Emerging market countries can include every
nation in the world except the United States, Canada, Japan, Australia, New
Zealand and most countries located in Western Europe. Investing in foreign
countries, particularly emerging market countries, entails the risk that news
and events unique to a country or region will affect those markets and their
issuers. Countries with emerging markets may have relatively unstable governments,
may present the risks of nationalization of businesses, restrictions on foreign
ownership and prohibitions on the repatriation of assets. The economies of emerging
markets countries also may be based on only a few industries, making them more
vulnerable to changes in local or global trade conditions and more sensitive to
debt burdens or inflation rates. Local securities markets may trade a small number
of securities and may be unable to respond effectively to increases in trading volume,
potentially making prompt liquidation of holdings difficult or impossible at times.

European Economic Risk. The Economic and Monetary Union of the European Union
(the "EU") requires member countries to comply with restrictions on inflation
rates, deficits, interest rates, debt levels and fiscal and monetary controls,
each of which may significantly affect every country in Europe. Decreasing
imports or exports, changes in governmental or EU regulations on trade, changes
in the exchange rate of the euro, the default or threat of default by an EU
member country on its sovereign debt, and/or an economic recession in an EU
member country may have a significant adverse effect on the economies of EU
member countries and on major trading partners outside Europe. The European
financial markets have recently experienced volatility and have been adversely
affected by concerns about economic downturns, credit rating downgrades, rising
government debt levels and possible default on or restructuring of government
debt in several European countries, including Greece, Ireland, Italy, Portugal
and Spain. A default or debt restructuring by any European country would
adversely impact holders of that country's debt, and sellers of credit default
swaps linked to that country's creditworthiness (which may be located in
countries other than those listed in the previous sentence). These events have
adversely affected the value and exchange rate of the euro and may continue to
significantly affect  the economies of every country in Europe, including EU
member countries that do not use the euro and non-EU member countries.

Basic Materials Sector Risk. Companies in the basic materials sector could
be adversely affected by commodity price volatility, exchange rates, import
controls and increased competition. Production of industrial materials often
exceeds demand as a result of overbuilding or economic downturns, leading to
poor investment returns. Companies in the basic materials sector are at risk
for environmental damage and product liability claims. Companies in the basic
materials sector may be adversely affected by depletion of resources, technical
progress, labor relations, and government regulations.

Financial Services Sector Risk. The financial services industries are subject
to extensive government regulation, can be subject to relatively rapid change
due to increasingly blurred distinctions between service segments, and can be
significantly affected by availability and cost of capital funds, changes in
interest rates, the rate of corporate and consumer debt defaults, and price
competition. In addition, the deterioration of the credit markets since late
2007 generally has caused an adverse impact in a broad range of markets,
including U.S. and international credit and interbank money markets generally,
thereby affecting a wide range of financial institutions and markets. In
particular, events in the financial sector since late 2008 have resulted,
and may continue to result, in an unusually high degree of volatility in
the financial markets, both domestic and foreign. This situation has created
instability in the financial markets and caused certain financial services
companies to incur large losses. Numerous financial services companies have
experienced substantial declines in the valuations of their assets, taken action
to raise capital (such as the issuance of debt or equity securities), or even
ceased operations. These actions have caused the securities of many financial
services companies to experience a dramatic decline in value. Issuers that have
exposure to the real estate, mortgage and credit markets have been particularly
affected by the foregoing events and the general market turmoil, and it is
uncertain whether or for how long these conditions will continue.

Small and Medium-Sized Company Risk. Investing in securities of small and
medium-sized companies involves greater risk than is customarily associated with
investing in larger, more established companies. These companies' securities may
be more volatile and less liquid than those of larger, more established companies.
These securities may have returns that vary, sometimes significantly, from the
overall stock market.

Non-Correlation Risk. The Fund's return may not match the return of the Index
for a number of reasons. For example, the Fund incurs a number of operating
expenses not applicable to the Index, and incurs costs in buying and selling
securities, especially when rebalancing the Fund's securities holdings to
reflect changes in the composition of the Index.

The Fund may not be fully invested at times, either as a result of cash flows
into the Fund or reserves of cash held by the Fund to meet redemptions and
expenses. If the Fund utilizes a sampling approach, its return may not correlate
as well with the return on the Index, as would be the case if it purchased all
of the securities in the Index with the same weightings as the Index.

Passive Management Risk. Unlike many investment companies, the Fund is not
"actively" managed. Therefore, it would not necessarily sell a security because
the security's issuer was in financial trouble unless that security is removed
from the Index.

Issuer-Specific Changes. The value of an individual security or particular type
of security can be more volatile than the market as a whole and can perform
differently from the value of  the market as a whole. The value of securities
of smaller issuers can be more volatile than that of larger issuers.

Non-Diversified Fund Risk. The Fund is considered non-diversified and can invest
a greater portion of assets in securities of individual issuers than a diversified
fund. Even though no single security weight may exceed 4.5% of the Index at the time
of each quarterly rebalance, changes in the market value of the Index's constituent
securities may result in the Fund being invested in the securities of individual
issuers (and making additional such investments in the case of creations of
additional Creation Units) in greater proportions. As a result, changes in the
market value of a single investment could cause greater fluctuations in Share
price than would occur in a diversified fund.

The Fund's Shares will change in value, and you could lose money by investing in
the Fund. The Fund may not achieve its investment objective. An investment in
the Fund has not been guaranteed, sponsored, recommended, or approved by the
United States, or any agency, instrumentality or officer of the United States,
has not been insured by the Federal Deposit Insurance Corporation (FDIC) and
is not guaranteed by and is not otherwise an obligation of any bank or insured
depository institution.

FundPerformance

The chart and table below provide some indication of the risks of investing in
the Fund by showing changes in the Fund's performance from year to year and by
showing how the Fund's average annual returns for one year and since inception
compare with those of the Index and a broad measure of market performance. The
Fund's past performance (before and after taxes) is not necessarily an
indication of how the Fund will perform in the future. Updated performance
information for the Fund is available at www.guggenheimfunds.com.

Calendar Year Total Return as of 12/31

The Fund commenced operations on November 9, 2007. The Fund's year-to-date total
return was -19.14% as of June 30, 2012.

During the periods shown in the chart above, the Fund's highest and lowest
calendar quarter returns were 44.84% and -26.14%, respectively, for the quarters

[1] The Fund has adopted a Distribution and Service (12b-1) Plan pursuant to which the Fund may bear a 12b-1 fee not to exceed 0.25% per annum of the Fund's average daily net assets. However, no such fee is currently paid by the Fund and the Board of Trustees has adopted a resolution that no such fee will be paid for at least 12 months from the date of this prospectus.

[2] The Fund's Investment Adviser has contractually agreed to reimburse Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, a portion of the Fund's licensing fees, offering costs up to 0.25% of average net assets, brokerage commissions and other trading expenses, taxes and extraordinary expenses such as litigation and other expenses not incurred in the ordinary course of the Fund's business) from exceeding 0.65% of average net assets per year (the "Expense Cap"), at least until December 31, 2015, and prior to such date the Investment Adviser may not terminate the arrangement without the approval of the Board of Trustees. For a period of five years subsequent to the Fund's commencement of operations, the Investment Adviser may recover from the Fund expenses reimbursed during the prior three years if the Fund's expense ratio, including the recovered expenses, falls below the Expense Cap. To the extent that the Fund incurs expenses that are excluded from the Expense Cap, the Fund's expense ratio will exceed the Expense Cap.

Guggenheim Frontier Markets ETF (Prospectus Summary) | Guggenheim Frontier Markets ETF

Guggenheim Frontier Markets ETF

Investment Objective

The Fund seeks investment results that correspond generally to the performance,
before the Fund's fees and expenses, of an equity index called the BNY Mellon
New Frontier DR Index (the "Index").

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund ("Shares"). Investors purchasing Shares in the secondary
market may be subject to costs (including customary brokerage commissions)
charged by their broker.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

Annual Fund Operating Expenses		Guggenheim Frontier Markets ETF
Management Fees		0.50%
Distribution and/or service (12b-1) fees	[1]
Other expenses		0.31%
Total annual Fund operating expenses		0.81%
Expense Reimbursements	[2]	0.11%
Total annual Fund operating expenses after Expense Reimbursements		0.70%

Example

This Example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other funds. The Example does not take into account
brokerage commissions that you pay when purchasing or selling Shares of the Fund.

The Example assumes that you invest $10,000 in the Fund for the time periods
indicated and then redeem all of your shares at the end of those periods. The
Example also assumes that your investment has a 5% return each year and that the
Fund's operating expenses remain the same. Although your actual costs may be higher
or lower, based on these assumptions your costs would be:

Expense Example (USD $)	Expense Example, with Redemption, 1 Year	Expense Example, with Redemption, 3 Years	Expense Example, with Redemption, 5 Years	Expense Example, with Redemption, 10 Years
Guggenheim Frontier Markets ETF	72	278	527	1,240

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells
securities (or "turns over" its portfolio). A higher portfolio turnover rate may
indicate higher transaction costs and may result in higher taxes when Shares are
held in a taxable account. These costs, which are not reflected in annual fund
operating expenses or in the Example, affect the Fund's performance. During the
most recent fiscal year ended May 31, 2012, the Fund's portfolio turnover rate
was 30% of the average value of its portfolio.

Principal Investment Strategies

The Fund, using a low cost "passive" or "indexing" investment approach, seeks to
replicate, before the Fund's fees and expenses, the performance of the Index.
The Index is composed of all liquid (as defined by the criteria set forth below)
American depositary receipts ("ADRs") and global depositary receipts ("GDRs") of
certain countries that are represented in the Index. As of August 31, 2012, the
Index was comprised of 38 constituents. The Index tracks the performance of
depositary receipts, in ADR or GDR form, that trade on the London Stock Exchange
("LSE"), New York Stock Exchange ("NYSE"), NYSE Arca, Inc. ("NYSE Arca"), NYSE
AMEX, and Nasdaq Stock Market ("NASDAQ") of companies from countries that are
defined as the "Frontier Market." The Bank of New York Mellon, the Fund's index
provider ("BNY Mellon" or the "Index Provider"), defines Frontier Market
countries based upon an evaluation of gross domestic product growth, per capita
income growth, experienced and expected inflation rates, privatization of
infrastructure and social inequalities. The countries currently are: Argentina,
Bahrain, Jordan, Kuwait, Lebanon, Oman, Qatar, United Arab Emirates, Egypt,
Ghana, Kenya, Malawi, Mauritius, Morocco, Nigeria, Tunisia, Zimbabwe, Bulgaria,
Croatia, Czech Republic, Estonia, Georgia, Kazakhstan, Latvia, Lithuania,
Poland, Romania, Slovak Republic, Slovenia, Ukraine, Bangladesh, Pakistan, Papua
New Guinea, Sri Lanka, Vietnam, Peru, Chile, Colombia, Ecuador, Jamaica, Panama
and Trinidad & Tobago. The universe of potential Index constituents includes all
liquid ADRs and GDRs which meet the criteria set forth under "Index Construction"
with respect to trading volume and market capitalization. As of August 31, 2012,
potential Index constituents include securities with free-float market
capitalizations greater than $100 million which may include securities of all
categories of market capitalizations, as defined by the Index Provider.

The Fund will invest at least 80% of its total assets in ADRs and GDRs that
comprise the Index or in the securities underlying such ADRs and GDRs. The
Fund also will normally invest at least 80% of its total assets in securities
of issuers from Frontier Market countries (whether directly or through ADRs
or GDRs), as defined by the Index Provider from time to time in the manner set
forth above. The Fund has adopted a policy that requires the Fund to provide
shareholders with at least 60 days notice prior to any material change in these
policies or the Index. The Board of Trustees of the Trust may change the Fund's
investment strategy and other policies without shareholder approval, except as
otherwise indicated.

The Fund may invest directly in one or more underlying securities represented by
the ADRs or GDRs comprising the Index under the following limited circumstances:
(a) when market conditions result in the underlying security providing improved
liquidity relative to the ADR or GDR; (b) when an ADR or GDR is trading at a
significantly different price than its underlying security; or (c) the timing
of trade execution is improved due to the local market in which an underlying
security is traded being open at different times than the market in which the
security's corresponding ADR or GDR is traded.

The Investment Adviser seeks a correlation over time of 0.95 or better between
the Fund's performance and the performance of the Index. A figure of 1.00 would
represent perfect correlation.

The Fund generally will invest in all of the securities comprising the Index in
proportion to their weightings in the Index. However, under various circumstances,
it may not be possible or practicable to purchase all of the securities in the
Index in those weightings. In those circumstances, the Fund may purchase a sample
of the securities in the Index in proportions expected by the Investment Adviser
to replicate generally the performance of the Index as a whole. There may also be
instances in which the Investment Adviser may choose to overweight another security
in the Index, or purchase (or sell) securities not in the Index which the Investment
Adviser believes are appropriate to substitute for one or more Index components, in
seeking to accurately track the Index. In addition, from time to time securities are
added to or removed from the Index. The Fund may sell securities that are represented
in the Index or purchase securities that are not yet represented in the Index in
anticipation of their removal from or addition to the Index.

Principal Investment Risks

Investors should consider the following risk factors and special considerations
associated with investing in the Fund, which may cause you to lose money.

Investment Risk. An investment in the Fund is subject to investment risk,
including the possible loss of the entire principal amount that you invest.

Equity Risk. The value of the equity securities held by the Fund may fall due to
general market and economic conditions, perceptions regarding the industries in
which the issuers of securities held by the Fund participate, or factors relating
to specific companies in which the Fund invests. For example, an adverse event,
such as an unfavorable earnings report, may depress the value of equity securities
of an issuer held by the Fund; the price of common stock of an issuer may be
particularly sensitive to general movements in the stock market; or a drop in the
stock market may depress the price of most or all of the common stocks and other
equity securities held by the Fund. In addition, equity securities of an issuer in
the Fund's portfolio may decline in price if the issuer fails to make anticipated
dividend payments because the issuer of the security experiences a decline in its
financial condition. Common stock is subordinated to preferred stocks, bonds and
other debt instruments in a company's capital structure, in terms of priority to
corporate income, and therefore will be subject to greater dividend risk than
preferred stocks or debt instruments of such issuers. In addition, while broad
market measures of common stocks have historically generated higher average
returns than fixed income securities, common stocks have also experienced
significantly more volatility in those returns.

Foreign Investment Risk. The Fund's investments in non-U.S. issuers may involve
unique risks compared to investing in securities of U.S. issuers, including less
market liquidity, generally greater market volatility than U.S. securities and
less complete financial information than for U.S. issuers. In addition, adverse
political, economic or social developments could undermine the value of the
Fund's investments or prevent the Fund from realizing the full value of its
investments. Financial reporting standards for companies based in foreign
markets differ from those in the United States. Finally, the value of the
currency of the country in which the Fund has invested could decline relative
to the value of the U.S. dollar, which may affect the value of the investment
to U.S. investors. The Fund will not enter into transactions to hedge against
declines in the value of the Fund's assets that are denominated in a foreign
currency.

Risks of Investing In Frontier Securities. Frontier market countries are
emerging market countries. Investment in securities in emerging market countries
involves risks not associated with investments in securities in developed
countries, including risks associated with expropriation and/or nationalization,
political or social instability, armed conflict, the impact on the economy as a
result of civil war, religious or ethnic unrest and the withdrawal or non-renewal
of any license enabling the Fund to trade in securities of a particular country,
confiscatory taxation, restrictions on transfers of assets, lack of uniform
accounting, auditing and financial reporting standards, less publicly available
financial and other information, diplomatic development which could affect U.S.
investments in those countries and potential difficulties in enforcing contractual
obligations. Emerging markets are subject to greater market volatility, lower
trading volume, political and economic instability, uncertainty regarding the
existence of trading markets and more governmental limitations on foreign investment
than more developed markets. In addition, securities in emerging markets may be
subject to greater price fluctuations than securities in more developed markets.
There may be less information publicly available with regard to emerging market
issuers and such issuers are not subject to the uniform accounting, auditing and
financial reporting standards applicable to U.S. issuers. There may be no single
centralized securities exchange on which securities are traded in emerging market
countries and the systems of corporate governance to which companies in emerging
markets are subject may be less advanced than that to which U.S. issuers are
subject, and therefore, shareholders in such companies may not receive many of
the protections available to shareholders of U.S. issuers. Securities law in many
emerging markets countries is relatively new and unsettled. Therefore, laws regarding
foreign investment in emerging market securities, securities regulation, title to
securities, and shareholder rights may change quickly and unpredictably. In addition,
the enforcement of systems of taxation at federal, regional and local levels in
emerging market countries may be inconsistent, and subject to sudden change.

Frontier countries generally have smaller economies or less developed capital
markets than traditional emerging markets, and, as a result, the risks of
investing in emerging market countries are magnified in frontier countries.
The economies of frontier countries are less correlated to global economic
cycles than those of their more developed counterparts and their markets
have low trading volumes and the potential for extreme price volatility and
illiquidity. This volatility may be further heightened by the actions of a
few major investors. For example, a substantial increase or decrease in cash
flows of mutual funds investing in these markets could significantly affect
local stock prices and, therefore, the price of Fund Shares. These factors make
investing in frontier countries significantly riskier than in other countries
and any one of them could cause the price of the Fund's Shares to decline.

Governments of many frontier countries in which the Fund may invest may exercise
substantial influence over many aspects of the private sector. In some cases,
the governments of such frontier countries may own or control certain companies.
Accordingly, government actions could have a significant effect on economic
conditions in a frontier country and on market conditions, prices and yields of
securities in the Fund's portfolio. Moreover, the economies of frontier countries
may be heavily dependent upon international trade and, accordingly, have been and
may continue to be, adversely affected by trade barriers, exchange controls, managed
adjustments in relative currency values and other protectionist measures imposed or
negotiated by the countries with which they trade. These economies also have been
and may continue to be adversely affected by economic conditions in the countries
with which they trade.

Certain foreign governments in countries in which the Fund may invest levy
withholding or other taxes on dividend and interest income. Although in some
countries a portion of these taxes are recoverable, the non-recovered portion
of foreign withholding taxes will reduce the income received from investments
in such countries.

From time to time, certain of the companies in which the Fund may invest may
operate in, or have dealings with, countries subject to sanctions or embargoes
imposed by the U.S. government and the United Nations and/or countries identified
by the U.S. government as state sponsors of terrorism. A company may suffer damage
to its reputation if it is identified as a company which operates in, or has
dealings with, countries subject to sanctions or embargoes imposed by the U.S.
government and the United Nations and/or countries identified by the U.S.
government as state sponsors of terrorism. As an investor in such companies, the
Fund will be indirectly subject to those risks.

Investment in equity securities of issuers operating in certain frontier
countries is restricted or controlled to varying degrees. These restrictions or
controls may at times limit or preclude foreign investment in equity securities
of issuers operating in certain frontier countries and increase the costs and
expenses of the Fund. Certain frontier countries require governmental approval
prior to investments by foreign persons, limit the amount of investment by
foreign persons in a particular issuer, limit the investment by foreign persons
only to a specific class of securities of an issuer that may have less advantageous
rights than the classes available for purchase by domiciliaries of the countries
and/or impose additional taxes on foreign investors. Certain frontier countries may
also restrict investment opportunities in issuers in industries deemed important to
national interests.

Frontier countries may require governmental approval for the repatriation of
investment income, capital or the proceeds of sales of securities by foreign
investors, such as the Fund. In addition, if deterioration occurs in a frontier
country's balance of payments, the country could impose temporary restrictions
on foreign capital remittances. The Fund could be adversely affected by delays
in, or a refusal to grant, any required governmental approval for repatriation
of capital, as well as by the application to the Fund of any restrictions on
investments. Investing in local markets in frontier countries may require the
Fund to adopt special procedures, seek local government approvals or take other
actions, each of which may involve additional costs to the Fund.

As of August 31, 2012, a significant percentage of the Index is comprised of
securities of companies from Chile, Colombia and Egypt. To the extent that the
Index is focused on securities of any one country, including Chile, Colombia and
Egypt, the value of the Index, and thus the Fund, will be especially affected by
adverse developments in such country, including the risks described above.

Political Risk. Certain of the frontier countries may be subject to a greater
degree of political and social instability than is the case in more developed
countries. Such instability may result from, among other things, authoritarian
governments or military involvement in political and economic decision-making,
including changes in government through extra-constitutional means, popular
unrest associated with demands for improved political, economic and social
conditions, internal insurgencies, hostile relations with neighboring countries
and ethnic, religious and racial disaffection. Some frontier countries may be
affected by a greater degree of public corruption and crime, including organized
crime.

Licensing, Custody and Settlement Risk. Approval of governmental authorities may
be required prior to investing in the securities of companies based in certain
frontier countries. Delays in obtaining such an approval would delay investments
in the particular country.

Rules adopted under the Investment Company Act of 1940, as amended, permit a
fund to maintain its foreign securities and cash in the custody of certain
eligible non-U.S. banks and securities depositories. Certain banks in foreign
countries that are eligible foreign sub-custodians may be recently organized or
otherwise lack extensive operating experience. In addition, in certain countries
there may be legal restrictions or limitations on the ability of the Fund to
recover assets held in custody by a foreign sub-custodian in the event of the
bankruptcy of the sub-custodian. Settlement systems in emerging markets may be
less well organized than in developed markets. Thus there may be a risk that
settlement may be delayed and that cash or securities of the Fund may be in
jeopardy because of failures of or defects in the systems. Under the laws of
certain countries in which the Fund may invest, the Fund may be required to
release local shares before receiving cash payment or may be required to make
cash payment prior to receiving local shares.

Certain countries in which the Fund may invest utilize share blocking schemes.
Share blocking refers to a practice, in certain foreign markets, where voting
rights related to an issuer's securities are predicated on these securities
being blocked from trading at the custodian or sub-custodian level, for a period
of time around a shareholder meeting. These restrictions have the effect of
prohibiting securities to potentially be voted (or having been voted), from
trading within a specified number of days before, and in certain instances,
after the shareholder meeting.

Share blocking may prevent the Fund from buying or selling securities for a
period of time. During the time that shares are blocked, trades in such
securities will not settle. The specific practices may vary by market and the
blocking period can last from a day to several weeks, typically terminating on a
date established at the discretion of the issuer.

Once blocked, the only manner in which to remove this block would be to withdraw
a previously cast vote, or to abstain from voting all together. The process for
having a blocking restriction lifted can be quite onerous, with the particular
requirements varying widely by country. In addition, in certain countries, the
block cannot be removed.

Share blocking may present operational challenges for the Fund and Authorized
Participants, including the effect that an imposed block would have on pending
trades. Pending trades may be caused to fail and could potentially remain
unsettled for an extended period of time. Fails may also expose the transfer
agent and the Fund to "Buy In" situations in which if unable to deliver shares
after a certain period of time, a counter party has the right to go to market,
purchase a security at the current market price and have any additional expense
borne by the fund or transfer agent.

As a result of the ramifications of voting ballots in share blocking proxy
markets, the Investment Adviser, on behalf of the Fund, reserves the right to
abstain from voting proxies in share blocking proxy markets.

Financial Services Sector Risk. The financial services industries are subject
to extensive government regulation, can be subject to relatively rapid change
due to increasingly blurred distinctions between service segments, and can be
significantly affected by availability and cost of capital funds, changes in
interest rates, the rate of corporate and consumer debt defaults, and price
competition. In addition, the deterioration of the credit markets since late
2007 generally has caused an adverse impact in a broad range of markets,
including U.S. and international credit and interbank money markets generally,
thereby affecting a wide range of financial institutions and markets. In
particular, events in the financial sector since late 2008 have resulted,
and may continue to result, in an unusually high degree of volatility in
the financial markets, both domestic and foreign. This situation has created
instability in the financial markets and caused certain financial services
companies to incur large losses. Numerous financial services companies have
experienced substantial declines in the valuations of their assets, taken action
to raise capital (such as the issuance of debt or equity securities), or even
ceased operations. These actions have caused the securities of many financial
services companies to experience a dramatic decline in value. Issuers that have
exposure to the real estate, mortgage and credit markets have been particularly
affected by the foregoing events and the general market turmoil, and it is
uncertain whether or for how long these conditions will continue.

Non-Correlation Risk. The Fund has historically experienced differences between
the Fund's return and that of the Index ("tracking error"), which often have
been substantial and exceed those experienced by many other ETFs. The tracking
error experienced by the Fund has generally arisen from the application of the
Fund's fair valuation policies to certain underlying securities which, despite
being listed on a stock exchange (as set forth under "Principal Investment
Strategies"), may not experience trades on a daily basis. The underlying Index
is not required to fair value its constituents. In addition, the Fund's return
may not match the return of the Index for a number of other reasons. For example,
the Fund incurs a number of operating expenses not applicable to the Index, and
incurs costs in buying and selling securities, especially when rebalancing the
Fund's securities holdings to reflect changes in the composition of the Index.

The Fund may not be fully invested at times, either as a result of cash flows
into the Fund or reserves of cash held by the Fund to meet redemptions and
expenses. If the Fund utilizes a sampling approach or otherwise holds
instruments other than those which constitute the Index, its return may not
correlate as well with the return on the Index, as would be the case if it
purchased all of the securities in the Index with the same weightings as the
Index.

Small and Medium-Sized Company Risk. Investing in securities of small and
medium-sized companies involves greater risk than is customarily associated with
investing in larger, more established companies. These companies' securities may
be more volatile and less liquid than those of larger, more established companies.
These securities may have returns that vary, sometimes significantly, from the
overall stock market.

Micro-Cap Company Risk. Micro-cap securities involve substantially greater risks
of loss and price fluctuations because their earnings and revenues tend to be
less predictable (and some companies may be experiencing significant losses),
and their share prices tend to be more volatile and their markets less liquid
than companies with larger market capitalizations. Micro-cap companies may be
newly formed or in the early stages of development, with limited product lines,
markets or financial resources and may lack management depth. In addition, there
may be less public information available about these companies. The shares of
micro-cap companies tend to trade less frequently than those of larger, more
established companies, which can adversely affect the pricing of these securities
and the future ability to sell these securities. Also, it may take a long time
before the Fund realizes a gain, if any, on an investment in a micro-cap company.

Passive Management Risk. Unlike many investment companies, the Fund is not
"actively" managed. Therefore, it would not necessarily sell a security because
the security's issuer was in financial trouble unless that security is removed
from the Index.

Issuer-Specific Changes. The value of an individual security or particular type
of security can be more volatile than the market as a whole and can perform
differently from the value of the market as a whole. The value of securities of
smaller issuers can be more volatile than that of larger issuers.

Non-Diversified Fund Risk. The Fund is considered non-diversified and can invest
a greater portion of assets in securities of individual issuers than a diversified
fund. Even though no single security weight may exceed 10% of the Index at the time
of each quarterly rebalance, changes in the market value of the Index's constituent
securities may result in the Fund being invested in the securities of individual
issuers (and making additional such investments in the case of creations of
additional Creation Units) in greater proportions. As a result, changes in the
market value of a single investment could cause greater fluctuations in share
price than would occur in a diversified fund.

The Fund's Shares will change in value, and you could lose money by investing in
the Fund. The Fund may not achieve its investment objective. An investment in
the Fund has not been guaranteed, sponsored, recommended, or approved by the
United States, or any agency, instrumentality or officer of the United States,
has not been insured by the Federal Deposit Insurance Corporation (FDIC) and is
not guaranteed by and is not otherwise an obligation of any bank or insured
depository institution.

[1] The Fund has adopted a Distribution and Service (12b-1) Plan pursuant to which the Fund may bear a 12b-1 fee not to exceed 0.25% per annum of the Fund's average daily net assets. However, no such fee is currently paid by the Fund and the Board of Trustees has adopted a resolution that no such fee will be paid for at least 12 months from the date of this prospectus.

[2] The Fund's Investment Adviser has contractually agreed to reimburse Fund expenses to the extent necessary to prevent the operating expenses of the Fund (excluding interest expenses, a portion of the Fund's licensing fees, offering costs up to 0.25% of average net assets, brokerage commissions and other trading expenses, taxes and extraordinary expenses such as litigation and other expenses not incurred in the ordinary course of the Fund's business) from exceeding 0.65% of average net assets per year (the "Expense Cap"), at least until December 31, 2015, and prior to such date the Investment Adviser may not terminate the arrangement without the approval of the Board of Trustees. For a period of five years subsequent to the Fund's commencement of operations, the Investment Adviser may recover from the Fund expenses reimbursed during the prior three years if the Fund's expense ratio, including the recovered expenses, falls below the Expense Cap. To the extent that the Fund incurs expenses that are excluded from the Expense Cap, the Fund's expense ratio will exceed the Expense Cap.
