Income & Treasury Limited Duration Portfolio of Funds (15-Month) Series 16

Under normal circumstances, the Trust will invest at least 80% of the value of its assets in common shares of closed-end investment companies (“closed-end funds”) that invest in various income-oriented securities of different asset classes and shares of an exchange-traded fund (“ETF”) that invests substantially all of its assets in short-term U.S. Treasury bonds. The Sponsor selects certain closed-end funds for the Trust that hold limited duration securities. In general, limited duration fixedincome securities may provide investors with lower interest rate sensitivity than longer duration securities. The duration of a bond is a measure of its price sensitivity to changes in interest rates based on the weighted average term to maturity of its interest and principal cash flows. The Sponsor generally selects closed-end funds that hold securities that have durations of five years or less, however, the average duration of the securities held by the closed-end funds may be longer at any time depending on market conditions. By including closed-end funds that invest in limited duration fixed-income securities, the Sponsor seeks to lower the overall volatility of the Trust portfolio in most interest rate environments. 

The asset classes in which the closed-end funds invest may include, but are not limited to: 

• government bonds; 
• mortgage-backed bonds; 
• convertible bonds; 
• preferred securities; 
• corporate bonds; 
• senior loans; 
• high yield securities or “junk” bonds; and 
• international bonds, including bonds from issuers located in emerging markets. 

Guggenheim Funds, through proprietary research and strategic alliances, will strive to select closed-end funds featuring the potential for current income, diversification and overall liquidity. 

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

The Sponsor has selected for the portfolio closed-end funds and an ETF believed to have the best potential to achieve the Trust’s investment objective. 

As of the Trust’s initial date of deposit (the “Inception Date”), 100% of the Trust’s portfolio is invested in a combination of shares of closed-end funds that invest in various income-oriented securities of different asset classes and an ETF that invests substantially all of its assets in short-term U.S. Treasury bonds. 

When selecting closed-end funds for inclusion in this portfolio the Sponsor looks at numerous factors. These factors include, but are not limited to: 

• Investment Objective. The sponsor favors funds that have a clear investment objective in line with the Trust’s objective and, based upon a review of publicly available information, appear to be maintaining it. 
• Premium/Discount. The Sponsor favors funds that are trading at a discount relative to their peers and relative to their long-term average. 
• Consistent Dividend. The Sponsor favors funds that have a history of paying a consistent and competitive dividend. 
• Performance. The Sponsor favors funds that have a history of strong relative performance (based on market price and net asset value) when compared to their peers and an applicable index. 
• Duration. The Sponsor considers the duration of the funds relative to their peers as well as the overall portfolio. 

The Sponsor will seek to select an ETF for inclusion in the Trust portfolio that invests substantially all of its assets in short-term U.S. treasury bonds in an effort to dampen the Trust’s duration sensitivity and lower the Trust’s overall volatility. When selecting the ETF the Sponsor looks at numerous factors. These factors include, but are not limited to: duration, maturity and coupon rate. Due to the current economic environment, U.S. Treasury bonds and ETFs that invest in U.S. Treasury bonds are generating yields that are at historic lows. While U.S. Treasury bonds are considered to be some of the most risk adverse securities available, if U.S. Treasury bond yields remain at its current levels, the ETF included in the Trust’s portfolio may not contribute to or may lower the Trust’s performance. In addition, Standard & Poor’s Rating Services recently lowered its long-term sovereign credit rating on the United States to “AA+” from “AAA.” This could impact the market prices and yields of the U.S. Treasury bonds held by the ETF in the Trust portfolio. As of the Inception Date, the ETF comprised approximately 20% of the Trust’s portfolio. 

An investment can be made in the ETF and closed-end funds held by the Trust without paying the sales fee, operating expenses and organization costs of the Trust.

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. Standard & Poor’s Rating Services recently lowered its long-term sovereign credit rating on the United States to “AA+” from “AAA,” which could lead to increased interest rates and volatility. Extraordinary steps have been taken by the governments of several leading countries to combat the economic crisis; however, the impact of these measures is not yet fully known and cannot be predicted. 
• The Trust includes an ETF. ETFs are investment pools that hold other securities. ETFs are subject to various risks, including management’s ability to meet the fund’s investment objective. Shares of ETFs may trade at a discount from their net asset value in the secondary market. This risk is separate and distinct from the risk that the net asset value of the ETF shares may decrease. The amount of such discount from net asset value is subject to change from time to time in response to various factors. The underlying ETF has management and operating expenses. You will bear not only your share of the Trust’s expenses, but also the expenses of the underlying ETF. By investing in an ETF, the Trust incurs greater expenses than you would incur if you invested directly in the ETF. 
• The ETF held by the Trust invests in U.S. Treasury obligations. U.S. Treasury obligations are direct obligations of the United States which are backed by the full faith and credit of the United States. U.S. Treasury obligations are generally not affected by credit risk, but are subject to changes in market value resulting from changes in interest rates. The value of U.S. Treasury obligations will be adversely affected by decreases in bond prices and increases in interest rates. 
• The Trust includes closed-end funds. Closed-end funds are actively managed investment companies that invest in various types of securities. Closed-end funds issue common shares that are traded on a securities exchange. Closed- End Funds are subject to various risks, including management’s ability to meet the closed-end fund’s investment objective and to manage the closed-end fund’s portfolio during periods of market turmoil and as investors’ perceptions regarding closed-end funds or their underlying investments change. Closed- End Funds are not redeemable at the option of the shareholder and they may trade in the market at a discount to their net asset value. Closed-end funds may also employ the use of leverage which increases risk and volatility. Instability in the auction rate preferred shares market may affect the volatility of closed-end funds that use such instruments to provide leverage. The underlying funds have management and operating expenses. You will bear not only your share of the Trust’s expenses, but also the expenses of the underlying funds. By investing in other funds, the Trust incurs greater expenses than you would incur if you invested directly in the funds. 
• The value of the fixed-income securities in the closed-end funds and ETF will generally fall if interest rates, in general, rise. Typically, fixed-income securities with longer periods before maturity are more sensitive to interest rate changes. A closed-end fund, ETF or an issuer of securities held by a Closed- End Fund or ETF may be unwilling or unable to make principal payments and/or to declare dividends in the future, may call a security before its stated maturity, or may reduce the level of dividends declared. This may result in a reduction in the value of your units. 
• The financial condition of a Closed- End Fund, ETF or an issuer of securities held by a closed-end fund or ETF may worsen, resulting in a reduction in the value of your units. This may occur at any point in time, including during the primary offering period. 
• Certain closed-end funds held by the Trust invest in preferred securities. Preferred securities are typically subordinated to 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 credit risk than those debt instruments. 
• Certain closed-end funds held by the Trust invest in bonds that are rated below investment-grade and are considered to be “junk” securities. Below investment-grade obligations are considered to be speculative and are subject to greater market and credit risks, and accordingly, the risk of non-payment or default is higher than with investment-grade securities. In addition, such securities may be more sensitive to interest rate changes and more likely to receive early returns of principal. Certain closed-end funds held by the Trust may invest in bonds that are rated as investment-grade by only one rating agency. As a result, such split-rated securities may have more speculative characteristics and are subject to a greater risk of default than securities rated as investment-grade by more than one agency. 
• Certain of the closed-end funds held by the Trust invest in mortgage-backed securities. Mortgage-backed securities represent direct or indirect participations in, or are secured by and payable from, mortgage loans secured by real property. Mortgage-backed securities are based on different types of mortgages, including those on commercial real estate or residential properties. Rising interest rates tend to extend the duration of mortgage-backed securities, making them more sensitive to changes in interest rates, and may reduce the market value of the securities. In addition, mortgage-backed securities are subject to prepayment risk, the risk that borrowers may pay off their mortgages sooner than expected, particularly when interest rates decline. This can reduce the closed-end fund’s, and therefore the Trust’s, returns because the closed-end fund may have to reinvest that money at lower prevailing interest rates. 
• Certain closed-end funds held by the Trust invest in senior loans. Borrowers under senior loans may default on their obligations to pay principal or interest when due. This non-payment would result in a reduction of income to the applicable closed-end fund, a reduction in the value of the senior loan experiencing nonpayment and a decrease in the net asset value of the closed-end fund. Although senior loans in which the closed-end funds invest may be secured by specific collateral, there can be no assurance that liquidation of collateral would satisfy the borrower’s obligation in the event of nonpayment of scheduled principal or interest or that such collateral could be readily liquidated. Senior loans in which the closed-end funds invest: — generally are of below investment-grade credit quality; — may be unrated at the time of investment; — generally are not registered with the Securities and Exchange Commission (“SEC”) or any state securities commission; and — generally are not listed on any securities exchange. In addition, the amount of public information available on senior loans generally is less extensive than that available for other types of assets. 
• Certain closed-end funds held by the Trust invest in convertible securities. Convertible securities generally offer lower interest or dividend yields than non-convertible fixed-income securities of similar credit quality because of the potential for capital appreciation. The market values of convertible securities tend to decline as interest rates increase and, conversely, to increase as interest rates decline. However, a convertible security’s market value also tends to reflect the market price of the common stock of the issuing company, particularly when that stock price is greater than the convertible security’s “conversion price.” Convertible securities fall below debt obligations of the same issuer in order of preference or priority in the event of a liquidation and are typically unrated or rated lower than such debt obligations. 
• Certain closed-end funds held by the Trust invest in foreign securities. Investment in foreign securities presents additional risk. Foreign risk is the risk that foreign securities will be more volatile than U.S. securities due to such factors as adverse economic, currency, political, social or regulatory developments in a country, including government seizure of assets, excessive taxation, limitations on the use or transfer of assets, the lack of liquidity or regulatory controls with respect to certain industries or differing legal and/or accounting standards. 
• Certain closed-end funds held by the Trust may invest in securities issued by entities located in emerging markets. Emerging markets are generally defined as countries with low per capita income in the initial stages of their industrialization cycles. The markets of emerging markets countries are generally more volatile than the markets of developed countries with more mature economies. 
• Current economic conditions may lead to limited liquidity and greater volatility. The markets for fixed-income securities, such as those held by the closed-end funds and the ETF, have experienced periods of illiquidity and volatility since the latter half of 2007. General market uncertainty and consequent repricing risk have led to market imbalances of sellers and buyers, which in turn have resulted in significant valuation uncertainties in a variety of fixed-income securities. These conditions resulted, and in many cases continue to result in, greater volatility, less liquidity, widening credit spreads and a lack of price transparency, with many debt securities remaining illiquid and of uncertain value. These market conditions may make valuation of some of the securities held by the closed-end fund and the ETF uncertain and/or result in sudden and significant valuation increases or declines in its holdings. 
• 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. 
• Please note that the Sponsor or an affiliate may be engaged as a service provider to certain closed-end funds held by the Trust and therefore certain fees paid by the Trust to such closed-end funds will be paid to the Sponsor or an affiliate for its services to such closed-end funds. In addition to the expenses of the units of the Trust, the Trust is subject to various expenses of closed-end funds. Please see the Trust prospectus for more complete risk information.
