Guggenheim US Capital Strength Portfolio Series 12

Under normal circumstances, the Trust will invest at least 80% of the value of its assets in common stocks of U.S. companies. The Trust invests in a portfolio of U.S. companies that the Sponsor believes have had strong valuations, returns on capital and balance sheets. To determine whether a company has an attractive valuation, the Sponsor compares valuation metrics against the selected company’s peer group. Strong returns on capital are evidenced by the company’s return on capital compared to the selected company's peer group. Companies with strong balance sheets are typically those entities that are less levered than their peers. However, there can be no assurance that the Trust's investment strategy will identify companies that will perform well in the future. The U.S.-listed common stock held by the Trust may include the common stock of U.S. and non-U.S. companies. As a result of this strategy, the Trust is concentrated in the consumer products sector.

The Trust’s portfolio is constructed by the Sponsor using the methodology described below:

• Begin with the largest 30% of U.S. companies in the S&P 1500.

• Focus on companies which have demonstrated several years of consistently higher return on equity, and which have debt leverage levels lower than the market or their industry peers.

• Select a portfolio of securities from the remaining universe by selecting the most attractive candidates, as determined by the Sponsor, from each sector for expected performance and risk, while maintaining diversification with limits on sector and growth/value concentration.

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.

• 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. 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.
