Convertible & Income Portfolio of Funds Series 37

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 substantially all of their assets in convertible securities and/or income-producing securities and shares of an exchange-traded funds (“ETF”) that invests substantially all of their assets in convertible securities.

The Closed-End Funds and ETFs included in the Trust’s portfolio invest in a wide range of convertible securities, income-producing equity securities of any market capitalization and debt securities. The convertible securities and debt securities may be rated below-investment grade through investment grade or may be unrated but deemed to be of comparable quality by a Closed- End Fund’s or ETF’s adviser. High-yield, below-investment grade securities or “junk” bonds are considered to be primarily speculative with respect to the issuer’s ability to make principal and interest payments and may be more volatile than higher rated securities of similar maturity. Additionally, they are subject to greater market, credit and liquidity risks than investment-grade securities.

The Closed-End Funds and ETFs included in the Trust’s portfolio invest in convertible securities and debt securities. The debt securities may include, but are not limited to, corporate bonds, high-yield bonds, senior loans and sovereign bonds. Additionally, the Closed-End Funds and ETFs may invest in convertible securities and debt securities with any maturity period. Typically, fixed-income securities with longer periods before maturity are more sensitive to interest rate changes. The Sponsor will also consider the duration of the securities held by the Closed-End Funds and the ETFs included in the Trust’s portfolio, however, those underlying securities may be of any duration. 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.

In addition, certain of the Closed-End Funds and the ETFs may invest in foreign securities, including securities issued by companies located in emerging markets.

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

The Sponsor has selected for the portfolio Closed-End Funds and ETFs 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 substantially all of their assets in convertible securities and/or income-producing securities, including but not limited to high-yield securities or “junk” bonds, and an ETF that invests substantially all of its assets in convertible securities.

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 ETFs for inclusion in the Trust portfolio that invests substantially all of their assets in convertible securities. When selecting the ETFs the Sponsor looks at numerous factors. These factors include, but are not limited to: maturity and liquidity. As of the Inception Date, the ETFs comprised approximately 30% of the Trust’s portfolio.

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. Changes in legal, political, regulatory, tax and economic conditions may cause fluctuations in markets and securities prices, which could negatively impact the value of the Trust. Additionally, events such war, terrorism, natural and environmental disasters and the spread of infectious illnesses or other public health emergencies may adversely affect the economy, various markets and issuers. Recently, the outbreak of a novel and highly contagious form of coronavirus (“COVID-19”) has adversely impacted global commercial activity and contributed to significant volatility in certain markets. Many governments and businesses have instituted quarantines and closures, which has resulted in significant disruption in manufacturing, supply chains, consumer demand and economic activity. The potential impacts are increasingly uncertain, difficult to assess and impossible to predict, and may result in significant losses. Any adverse event could materially and negatively impact the value and performance of Trust and the Trust’s ability to achieve its investment objectives. 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.
• 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. 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 Trust includes ETFs. 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 premium or discount from their net asset value in the secondary market. If the Trust has to sell an ETF share when the share is trading at a discount, the Trust will receive a price that is less than the ETF’s net asset value. 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 ETFs have management and operating expenses. You will bear not only your share of the Trust’s expenses, but also the expenses of the underlying ETFs. By investing in ETFs, the Trust incurs greater expenses than you would incur if you invested directly in the ETFs.
• The ETFs and Closed-End Funds are subject to annual fees and expenses, including a management fee. Unitholders of the Trust will bear these fees in addition to the fees and expenses of the Trust. See “Fees and Expenses” for additional information.
• The ETFs and 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.
• The value of the fixed-income securities in the Closed-End Funds and ETFs 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. In addition, the duration of a bond will also affect its price sensitivity to interest rate changes. For example, if a bond has a duration of 5 years and interest rates go up by 1%, it can be expected that the bond price will move down by 5%. The Trust may be subject to greater risk of rising interest rates than would normally be the case due to the current period of historically low rates.
• 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 distributions in the future, may call a security before its stated maturity, or may reduce the level of distributions declared. Issuers may suspend dividends during the life of the Trust. 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. As the Trust is unmanaged, a downgraded security will remain in the portfolio.
• Certain Closed-End Funds and the ETFs 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 primarily speculative with respect to the issuer’s ability to make principal and interest payments and may be more volatile than higher rated securities of similar maturity. Additionally, they are subject to greater market, credit and liquidity risks than investment-grade securities. 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 in falling rate environments.
• Certain Closed-End Funds and the ETFs held by the Trust may invest in bonds that are rated as investmentgrade 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 rating agency.
• Certain Closed-End Funds and the ETFs 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 and the ETFs held by the Trust may invest in securities issued by companies headquartered or incorporated in countries considered to be emerging markets. Because their financial markets may be very small, prices of financial instruments in emerging market countries may be volatile and difficult to determine. Financial instruments of issuers in these countries may have lower overall liquidity than those of issuers in more developed countries. Financial and other reporting by companies and government entities also may be less reliable or difficult to obtain in emerging market countries. In addition, foreign investors are subject to a variety of special restrictions in many emerging market countries. Shareholder claims and regulatory actions that are available in the U.S. may be difficult or impossible to pursue in emerging market countries. Risks of investing in developing or emerging countries also include the possibility of investment and trading limitations, delays and disruptions in settlement transactions, market manipulation concerns, political uncertainties and dependence on international trade and development assistance.
• Economic conditions may lead to limited liquidity and greater volatility. The markets for fixed-income securities, such as those held by certain Closed-End Funds and the ETFs, may experience periods of illiquidity and volatility. 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 a Closed-End Fund and the ETFs uncertain and/or result in sudden and significant valuation increases or declines in its holdings.
• Certain Closed-End Funds held by the Trust invest in common stocks. Common stocks represent a proportional share of ownership in a company. Common stock prices fluctuate for several reasons including changes in investors’ perceptions of the financial condition of an issuer, changes in the general condition of the relevant stock market, such as the market volatility recently exhibited, or when political or economic events affect the issuers. Common stock prices may also be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase.
• Certain Closed-End Funds and the ETFs held by the Trust may invest in securities issued by small-capitalization and mid-capitalization companies. These securities customarily involve more investment risk than securities of large-capitalization companies. Small-capitalization and mid-capitalization companies may have limited product lines, markets or financial resources and may be more vulnerable to adverse general market or economic developments.
• The Trust may be susceptible to potential risks through breaches in cybersecurity. A breach in cybersecurity refers to both intentional and unintentional events that may cause the Trust to lose proprietary information, suffer data corruption or lose operational capacity. Such events could cause the Sponsor of the Trust to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. In addition, cybersecurity breaches of the Trust’s third-party service providers, or issuers in which the Trust invests, can also subject the Trust to many of the same risks associated with direct cybersecurity breaches.
• The Trust is subject to risks arising from various operational factors and their service providers. Operational factors include, but not limited to, human error, processing and communication errors, errors of the Trust’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. Additionally, the Trust may be subject to the risk that a service provider may not be willing or able to perform their duties as required or contemplated by their agreements with the Trust. Although the Trust seeks to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.
• 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.
