INDEX METHODOLOGY

The Index methodology is published at www.zacks.com. The Index selection methodology is designed to identify companies with potentially high income and superior risk-return profiles as determined by Zacks. The objective of the Index is to select a diversified group of securities with the potential to have a yield in excess of and outperform, on a risk adjusted basis, the Dow Jones US Select Dividend Index and other benchmark indices.

The Index constituent selection methodology utilizes multi-factor proprietary selection rules to identify those securities that offer the greatest potential from a yield and risk/return perspective while maintaining industry diversification. The approach is specifically designed to enhance investment applications and investability. The constituent selection process, as well as the ranking, reconstitution and rebalancing of the Index, is repeated quarterly.

INDEX CONSTRUCTION

1. Potential Index constituents include all U.S. stocks and ADRs that pay dividends, as well as REITs, MLPs, closed-end funds, Canadian royalty trusts and traditional preferred stocks.
2. The Index is comprised of approximately the 125 to 150 highest-ranking securities chosen using a rules-based quantitative ranking methodology proprietary to Zacks. Half (50%) or more of the portfolio will consist of dividend-paying common stocks. Closed-end funds are limited to 10% of the portfolio. MLPs may make up one-quarter (25%) of the portfolio. Exposure to all other categories of investment type (ADRs, REITs and preferred stock) other than U.S. common stock are limited to a 20% maximum per investment type.
3. Each company within each investment type is ranked using a quantitative rules-based methodology that includes yield, company growth, liquidity, relative value and other factors and is sorted from highest to lowest.
4. The approximately 125 to 150 constituents are chosen and are weighted based on a proprietary method developed by Zacks within each investment type.
5. The constituent selection process, as well as the ranking, reconstitution and rebalancing of the Index, is repeated quarterly.
6. The securities comprising the portfolio are regularly reviewed for deletion or dilution based on factors determined by Zacks.

RISKS AND OTHER CONSIDERATIONS

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. Equity risk is the risk that the value of the equity securities held by the Fund will 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, among other reasons, 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.

Preferred Stock Risk. There are certain additional risks associated with investing in preferred securities, including, but not limited to, (i) preferred securities may include provisions that permit the issuer, at its discretion, to defer or omit distributions for a stated period without any adverse consequences to the issuer; (ii) preferred securities are generally subordinated to bonds and other debt instruments in a company’s capital structure in terms of having priority to corporate income and liquidation payments, and therefore will be subject to greater credit risk than more senior debt instruments; preferred securities may be substantially less liquid than many other securities, such as common stocks or U.S. Government securities; generally, traditional preferred securities offer no voting rights with respect to the issuing company unless preferred dividends have been in arrears for a specified number of periods, at which time the preferred security holders may elect a number of directors to the issuer’s board; in certain varying circumstances, an issuer of preferred securities may redeem the securities prior to a specified date.

Foreign Investment Risk. The Fund’s investments in non-U.S. issuers, although limited to ADRs, may involve unique risks compared to investing in securities of U.S. issuers, including, among others, 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. In addition, the underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited securities. Issuers of unsponsored depositary receipts are not contractually obligated to disclose material information in the U.S. and, therefore, such information may not correlate to the market value of the unsponsored depositary receipt.

REIT Risk. Investments in securities of real estate companies involve risks. These risks 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, a REIT that fails to comply with federal tax requirements affecting REITs may be subject to federal income taxation, or 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 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.

MLP 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. Investments in securities of other investment companies involve risks, including, among others, the fact that 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.

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. These events have included, but are not limited to, the U.S. government’s placement of the Federal National Mortgage Association and the Federal Home Loan Mortgage Corporation under conservatorship, the bankruptcy filing of Lehman Brothers Holdings Inc., the sale of Merrill Lynch to Bank of America, the U.S. government support of American International Group, Inc., the sale of Wachovia to Wells Fargo, reports of credit and liquidity issues involving certain money market mutual funds, and emergency measures by the U.S. and foreign governments banning short-selling. 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. Moreover, certain financial companies have avoided collapse due to intervention by the U.S. regulatory authorities (such as the Federal Deposit Insurance Corporation or the Federal Reserve System), but such interventions have often not averted a substantial decline in the value of such companies’ common stock. 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 more established companies. These companies’ stocks may be more volatile and less liquid than those of more established companies. These stocks may have returns that vary, sometimes significantly, from the overall stock market.

Below-Investment Grade Securities Risk. The Fund may invest in certain preferred stocks that are rated below investment grade. Preferred stocks that are not investment grade are high yield, high risk securities. These securities offer a higher yield than other, higher rated securities, but they carry a greater degree of risk and are considered speculative by the major credit rating agencies. Preferred stocks rated below investment grade may be issued by companies that are restructuring, are smaller and less creditworthy, or are more highly indebted than other companies. This means that they may have more difficulty making scheduled dividend payments. Changes in the value of preferred stocks rated below investment grade are influenced more by changes in the financial and business position of the issuing company than by changes in interest rates when compared to investment grade preferred stocks.

Portfolio Turnover Risk. The Fund may engage in active and frequent trading of its portfolio securities in connection with the quarterly rebalancing of the Index, and therefore the Fund’s investments. A portfolio turnover rate of 200%, for example, is equivalent to the Fund buying and selling all of its securities two times during the course of the year. A high portfolio turnover rate (such as 100% or more) could result in high brokerage costs. While a high portfolio turnover rate can result in an increase in taxable capital gains distributions to the Fund’s shareholders, the Fund will seek to utilize the creation and redemption in kind mechanism to minimize capital gains to the extent possible.

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. Because 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.

Replication 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.

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.

As with any investment, you should consider how your investment will be taxed. The tax information contained in the prospectus is provided as general information. Investors should consult their own tax professional about the tax consequences of an investment as Guggenheim Funds Distributors, Inc. does not offer tax advice.

The Fund will issue and redeem Shares at NAV only in a large specified number of Shares called a “Creation Unit” or multiples thereof. A Creation Unit consists of 50,000 Shares. The Fund generally issues and redeems Creation Units principally in-kind. Except when aggregated in Creation Units, the Shares are not redeemable securities of the Fund. Individual Shares of the Fund may only be purchased and sold in secondary market transactions through brokers. Shares of the Fund are listed for trading on NYSE Arca, Inc. (“NYSE Arca”) and because Shares trade at market prices rather than NAV, Shares of the Fund may trade at a price greater than or less than NAV.

Investors buying or selling ETF shares on the secondary market may incur brokerage costs and other transactional fees. Shares of ETFs may fluctuate in price due to daily changes in trading volume. At times, shares may not have a high volume of trading.
