The loss of your money is a principal risk of investing in the Fund. Investments in the Fund are subject to investment risks, including the possible loss of some or the entire principal amount invested. The Fund is subject to certain risks, including the principal risks noted below, any of which may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return, and ability to meet its investment objectives. An investment in the Fund is not a deposit or obligation of any bank, is not endorsed or guaranteed by any bank, and is not insured by the Federal Deposit Insurance Corporation or any other government agency. The following describes the risks the Fund bears directly or indirectly through investments in Closed-End Funds:

Closed-End Fund Risk. Closed-end funds involve investment risks different from those associated with other investment companies. First, the shares of closed-end funds frequently trade at a premium or discount relative to their NAV. When the Fund purchases shares of a closed-end fund at a discount to its NAV, there can be no assurance that the discount will decrease, and it is possible that the discount may increase and affect whether the Fund will a realize gain or loss on the investment. Second, many closed end funds use leverage, or borrowed money, to try to increase returns. Leverage is a speculative technique and its use by a closed-end fund entails greater risk and leads to a more volatile share price. If a closed-end fund uses leverage, increases and decreases in the value of its share price will be magnified. The closed-end fund will also have to pay interest or dividends on its leverage, reducing the closed-end fund’s return. Third, many closed-end funds have a policy of distributing a fixed percentage of net assets regardless of the fund’s actual interest income and capital gains. Consequently, distributions by a closed-end fund may include a return of capital, which would reduce the fund’s NAV and its earnings capacity. Finally, closed-end funds are allowed to invest in a greater amount of illiquid securities than open-end mutual funds. Investments in illiquid securities pose risks related to uncertainty in valuations, volatile market prices, and limitations on resale that may have an adverse effect on the ability of the fund to dispose of the securities promptly or at reasonable prices.

Fund of Funds Risk. The Fund is a “fund of funds.” The term “fund of funds” is typically used to describe investment companies, such as the Fund, whose principal investment strategy involves investing in other investment companies, including closed-end funds and money market mutual funds. Investments in other funds subject the Fund to additional operating and management fees and expenses. For instance, investors in the Fund will indirectly bear fees and expenses charged by the funds in which the Fund invests, in addition to the Fund’s direct fees and expenses. The Fund’s performance depends in part upon the performance of the funds’ investment advisor, the strategies and instruments used by the funds, and the Advisor’s ability to select funds and effectively allocate Fund assets among them.

Control of Closed-End Funds Risk. Although the Fund and the Advisor will evaluate regularly each Portfolio Fund to determine whether its investment program is consistent with the Fund’s investment objective, the Advisor will not have any control over the investments made by a Portfolio Fund. The investment advisor to each Portfolio Fund may change aspects of its investment strategies at any time. The Advisor will not have the ability to control or otherwise influence the composition of the investment portfolio of a Portfolio Fund.

Fixed Income Securities Risk. When the Portfolio Funds invest in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise in interest rates causes a decline in the value of fixed income securities. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Other risk factors include credit risk (the debtor may default), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation later than expected), and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

Credit Risk. There is a risk that issuers will not make payments on fixed income securities held by the Portfolio Funds, resulting in losses to the Fund. In addition, the credit quality of fixed income securities held by the Portfolio Funds may be lowered if an issuer’s financial condition changes. The issuer of a fixed income security may also default on its obligations.

Interest Rate Risk. Interest rate risk is the risk that fixed income prices overall will decline over short or even long periods of time due to rising interest rates. Securities with longer maturities and durations tend to be more sensitive to interest rates than securities with shorter maturities and durations. For example, (a) if interest rates go up by 1.0%, the price of a 4% coupon bond will decrease by approximately 1.0% for a bond with 1 year to maturity and approximately 4.4% for a bond with 5 years to maturity and (b) the price of a portfolio with a duration of 5 years would be expected to fall approximately 5.0% if interest rates rose by 1.0% and a portfolio with a duration of 2 years would be expected to fall approximately 2.0% if interest rates rose by 1.0%.

Junk Bond Risk. Lower-quality bonds, known as “high yield” or “junk” bonds, present greater risk than bonds of higher quality, including an increased risk of default. An economic downturn or period of rising interest rates could adversely affect the market for these bonds and reduce a Portfolio Fund’s ability to sell its bonds. The lack of a liquid market for these bonds could decrease the Fund’s share price.

Prepayment Risk. During periods of declining interest rates, prepayment of debt securities usually accelerates. Prepayment may shorten the effective maturities of these securities, reducing their yield and market value, and the Portfolio Funds may have to reinvest at a lower interest rate.

Derivatives Risk. The Fund may invest indirectly in derivatives through its investments in shares of the Portfolio Funds. The Portfolio Funds may use derivative instruments, which derive their value from the value of an underlying security, currency, or index. Derivative instruments involve risks different from direct investments in the underlying assets, including: imperfect correlation between the value of the derivative instrument and the underlying assets; risks of default by the other party to the derivative instrument; risks that the transactions may result in losses of all or in excess of any gain in the portfolio positions; and risks that the transactions may not be liquid.

Investment Risk. Various sectors of the global financial markets have been experiencing an extended period of adverse conditions. Market uncertainty has increased dramatically, particularly in the United States and Europe, and adverse market conditions have expanded to other markets. These conditions have resulted in disruption of markets, periods of reduced liquidity, greater volatility, general volatility of spreads, an acute contraction in the availability of credit and a lack of price transparency. The long-term impact of these events is uncertain but could continue to have a material effect on general economic conditions, consumer and business confidence, and market liquidity.

Major public health issues, such as COVID-19, have at times, and may in the future impact the Fund. The COVID-19 pandemic caused substantial market volatility and global business disruption and impacted the global economy in significant and unforeseen ways. Any public health emergency, including the COVID-19 pandemic or any outbreak of other existing or new epidemic diseases or the threat thereof, and the resulting financial and economic market uncertainty, could have a material adverse impact on the Fund or its investments. Moreover, changes in interest rates, travel advisories, quarantines and restrictions, disrupted supply chains and industries, impact on labor markets, reduced liquidity or a slowdown in U.S. or global economic conditions resulting from a future public health crisis may also adversely affect the Fund or its investments. COVID-19, or any other health crisis and the current or any resulting financial, economic and capital markets environment, and future developments in these and other areas present uncertainty and risk with respect to the Fund’s NAV, performance, financial condition, results of operations, ability to pay distributions, make share repurchases and portfolio liquidity, among other factors.

Economic problems in a single country are increasingly affecting other markets and economies, and a continuation of this trend could adversely affect global economic conditions and world markets. Uncertainty and volatility in the financial markets and political systems of the U.S. or any other country, including volatility as a result of the ongoing conflicts between Russia and Ukraine and Israel and Hamas and the rapidly evolving measures in response, may have adverse spill-over effects into the global financial markets generally.

Convertible Securities Risk. Convertible securities are hybrid securities that have characteristics of both fixed income and equity securities and are subject to risks associated with both fixed income and equity securities described below.

Cybersecurity Risk. As part of its business, the Advisor processes, stores, and transmits large amounts of electronic information, including information relating to the transactions of the Fund. The Advisor and the Fund are therefore susceptible to cybersecurity risk. Cybersecurity failures or breaches of the Fund or its service providers have the ability to cause disruptions and impact business operations, potentially resulting in financial losses, the inability of Fund shareholders to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, and/or reputational damage. The Fund and its shareholders could be negatively impacted as a result.

Equity Securities Risk. Fluctuations in the value of equity securities held by the Portfolio Funds will cause the NAV of the Fund to fluctuate. Equity securities may decline in price if the issuer fails to make anticipated dividend payments. Common stock is subject to greater dividend risk than preferred stocks or debt instruments of the same issuer. In addition, equity securities have experienced significantly more volatility in returns than other asset classes.

Preferred Stock Risks. Generally, preferred stockholders have no voting rights with respect to the issuing company unless certain events occur. In addition, preferred stock will be subject to greater credit risk than debt instruments of an issuer and could be subject to interest rate risk like fixed income securities, as described below. An issuer’s board of directors is generally not under any obligation to pay a dividend (even if dividends have accrued) and may suspend payment of dividends on preferred stock at any time. There is also a risk that the issuer will default and fail to make scheduled dividend payments on the preferred stock held by the Portfolio Funds.

Foreign Securities Risk. The Fund may invest indirectly in foreign securities through its investments in shares of Portfolio Funds. Foreign securities involve investment risks different from those associated with domestic securities. Changes in foreign economies and political climates are more likely to affect the Fund than investments in domestic securities. The value of foreign currency denominated securities or foreign currency contracts is affected by the value of the local currency relative to the U.S. dollar. There may be less government supervision of foreign markets, resulting in non-uniform accounting practices and less publicly available information about issuers of foreign currency denominated securities. The value of foreign investments may be affected by changes in exchange control regulations, application of foreign tax laws (including withholding tax), changes in governmental administration or economic or monetary policy (in this country or abroad), or changed circumstances in dealings between nations. In addition, foreign brokerage commissions, custody fees, and other costs of investing in foreign securities are generally higher than in the United States. Investments in foreign issues could be affected by other factors not present in the United States, including expropriation, armed conflict, confiscatory taxation, and potential difficulties in enforcing contractual obligations.

General Investment Risks. All investments in securities and other financial instruments involve a risk of financial loss. No assurance can be given that the Fund’s investment program will be successful. Investors should carefully review the descriptions of the Fund’s investments and their risks described in this prospectus and the Fund’s Statement of Additional Information.

Investment Advisor Risk. The Advisor’s ability to choose suitable investments has a significant impact on the ability of the Fund to achieve its investment objectives. The portfolio managers’ experience is discussed in the section of this prospectus entitled “Management of the Funds – Investment Advisor.”

Quantitative Model Risk. Securities or other investments selected using quantitative methods may perform differently from the market as a whole. There can be no assurance that these methodologies will enable the Fund to achieve its objective.

Leverage Risk. Although the Fund will not itself employ leverage, the Portfolio Funds will often employ leverage, subject to investment company limits set forth by the U.S. Securities and Exchange Commission (the “SEC”). There can be no assurance that a leveraging strategy will be successful during any period in which it is employed.

Loans Risk. Investments in loans may subject the Fund to heightened credit risks because loans may be highly leveraged and susceptible to the risks of interest deferral, default, and/or bankruptcy.

Management Style Risk. Different types of securities tend to shift into and out of favor with investors depending on market and economic conditions. The returns from the types of investments purchased by the Fund (e.g., closed-end funds which pay regular periodic cash distributions) may at times be better or worse than the returns from other types of funds. Each type of investment tends to go through cycles of performing better or worse than the market in general. The performance of the Fund may thus be better or worse than the performance of funds that focus on other types of investments, or that have a broader investment style.

Market Risk. Market risk refers to the possibility that the value of securities held by the Fund may decline due to daily fluctuations in the market. Market prices for securities change daily as a result of many factors, including developments affecting the condition of both individual companies and the market in general. The price of a security may even be affected by factors unrelated to the value or condition of its issuer, such as changes in interest rates, economic and political conditions, and general market conditions. The Fund’s performance per share will change daily in response to such factors.

Money Market Mutual Fund Risk. The Fund may invest in money market mutual funds in order to manage its cash component. An investment in a money market mutual fund is not insured or guaranteed by a Federal Deposit Insurance Corporation or any other government agency. Although such funds seek to preserve the value of the Fund’s investment at $1.00 per share, it is possible to lose money by investing in a money market mutual fund.
