Dow Jones Value Dividend Focus Portfolio Series 15

The Sponsor, with the assistance of Guggenheim Partners Investment Management, LLC (“GPIM”), an affiliate of the Sponsor and Guggenheim Partners, LLC, has selected the securities to be included in the Trust’s portfolio.

See “Investment Policies” in Part B of the prospectus for additional information.

The Trust’s portfolio is constructed and the securities are selected approximately five business days prior to the initial date of deposit (the “Inception Date”) using the methodology described below.

In constructing the Trust portfolio, 50 securities will be selected based on the following fundamentally-based quantitative criteria:

• Begin with all companies listed in the Dow Jones U.S. Top-Cap Value Total Stock Index, which is a combination of the Dow Jones U.S. Large-Cap Value Total Stock Index and the Dow Jones U.S. Mid-Cap Value Total Stock Market Index.

• Exclude companies with a price per share of less than $5 and more than $500.

• Exclude companies with a 30-day average daily traded value of less than $1 million.

• Exclude companies with an indicated dividend yield of zero. Indicated dividend yield is a company’s most recently announced dividend, annualized based on dividend frequency and divided by market price (abnormal or special dividends are not included).

• Exclude 20% of the remaining companies with the lowest indicated dividend yield.

• Exclude 20% of the companies in the starting index with the highest standard deviation of daily returns for the trailing year, as provided by FactSet.

• Select the 100 companies with the highest GIQ Implied Risk Premium based on the methodology described below.

• Select the top 50 companies by indicated dividend yield and weight the portfolio by indicated dividend yield, subject to a 5% cap for each individual security on the day the strategy generates the final portfolio. (A company’s weight in the portfolio is derived by dividing the indicated dividend yield of each company by the sum of all indicated dividend yields for the 50 selected companies). Please note that due to the fluctuating nature of security prices, the weighting of an individual security in the Trust may be greater than 5% of the portfolio after the portfolio selection date.

IQ Implied Stock Risk Premium

The GIQ (“Guggenheim Intelligent Quantitative”) Implied Risk Premium seeks to measure the market implied discount rate (in excess to risk free rates) that is embedded in the price of a company’s stock. To determine the Implied Risk Premium for a given company, the company’s future cash flows are estimated through a forward-looking discounted free cash flow (“FCF”) model that takes into account each firm’s current balance sheet composition, returns on capital, and normalization assumptions that include excess returns on capital approaching industry average levels over a long-term horizon. The market price of the stock of each firm is used to solve for the discount rate that is required to equate future modeled cash flow streams to current equity value.

DEFINITIONS: Indicated Dividend Yield is a company’s most recently announced dividend, annualized based on dividend frequency and divided by market price (abnormal or special dividends are not included). The GIQ (“Guggenheim Intelligent Quantitative”) Implied Risk Premium seeks to measure the market implied discount rate (in excess to risk free rates) that is embedded in the price of a company’s stock. To determine the Implied Risk Premium for a given company, the company’s future cash flows are estimated through a forward-looking discounted free cash flow (“FCF”) model that takes into account each firm’s current balance sheet composition, returns on capital, and normalization assumptions that include excess returns on capital approaching industry average levels over a long-term horizon.

As with all investments, you may lose some or all of your investment in the Trust. No assurance can be given that the Trust’s investment objective will be achieved. The Trust also might not perform as well as you expect. This can happen for reasons such as these:

• Securities prices can be volatile. The value of your investment may fall over time. Market value fluctuates in response to various factors. These can include stock market movements, purchases or sales of securities by the Trust, government policies, litigation, and changes in interest rates, inflation, the financial condition of the securities’ issuer or even perceptions of the issuer. Units of the Trust are not deposits of any bank and are not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

• Due to the current state of the economy, the value of the securities held by the Trust may be subject to steep declines or increased volatility due to changes in performance or perception of the issuers. Starting in December 2007, economic activity declined across all sectors of the economy, and the United States experienced increased unemployment. The economic crisis affected the global economy with European and Asian markets also suffering historic losses. In addition, Standard & Poor’s Rating Services lowered its long-term sovereign credit rating on the United States to “AA+” from “AAA.” Effects of the economic crisis can still be felt in many countries around the world and may have an impact on the securities held by the Trust.

• Share prices or dividend rates on the securities in the Trust may decline during the life of the Trust. There is no guarantee that share prices of the securities in the Trust will not decline and that the issuers of the securities will declare dividends in the future and, if declared, whether they will remain at current levels or increase over time.

• The Trust is concentrated in the consumer products sector. As a result, the factors that impact the consumer products sector will likely have a greater effect on this Trust than on a more broadly diversified Trust. Some of the risks associated with the consumer products sector are listed below. General risks of companies in the consumer products sector include cyclicality of revenues and earnings, economic recession, currency fluctuations, changing consumer tastes, extensive competition, product liability litigation and increased government regulation. A weak economy and its effect on consumer spending would adversely affect companies in the consumer products sector.

• The Trust invests in securities issued by mid-capitalization companies. These securities customarily involve more investment risk than securities of large-capitalization companies. Mid-capitalization companies may have limited product lines, markets or financial resources and may be more vulnerable to adverse general market or economic developments.

• Inflation may lead to a decrease in the value of assets or income from investments.

• The Sponsor does not actively manage the portfolio. The Trust will generally hold, and may, when creating additional units, continue to buy, the same securities even though a security’s outlook, market value or yield may have changed.
