Purpose of Fee Table , Note [Text Block]

The following table shows the Fund’s expenses, which are borne directly or indirectly by holders of the Fund’s common shares, including preferred shares offering expenses, as a percentage of net assets attributable to common shares. All expenses of the Fund will be borne, directly or indirectly, by the common shareholders. Amounts are for the current fiscal year.

General Description of Registrant [Abstract]

Risk Factors [Table Text Block]

Principal Risk Factors

Leverage Risk

The Fund currently uses, and intends to continue to use, leverage for investment purposes by issuing preferred stock. “Leverage” for these purposes means the ratio by which the aggregate amount of senior securities representing indebtedness of the Fund plus the aggregate involuntary liquidation preference of the Fund’s preferred stock bears to the Fund’s total assets. As of December 31, 2022, the amount of leverage represented approximately 22%of the Fund’s net assets. All series of the Fund’s preferred stock have the same seniority with respect to distributions and liquidation preference. Preferred stock has seniority over common stock with respect to distributions and upon liquidation of the Fund.

The Fund’s leveraged capital structure creates special risks not associated with unleveraged funds having similar investment objectives and policies. The Fund’s use of leverage, which can be described as exposure to changes in price at a ratio greater than the amount of equity invested, either through the issuance of preferred stock, borrowing or other forms of market exposure, magnifies both the favorable and unfavorable effects of price movements in the investments made by the Fund. The Fund’s leveraged capital structure creates special risks not associated with unleveraged funds having similar investment objectives and policies. The Fund cannot assure that the issuance of preferred stock will result in a higher yield or return to the holders of the common stock. Also, as the Fund is utilizing leverage, a decline in NAV could affect the ability of the Fund to make common stock distributions and such a failure to pay dividends or make distributions could result in the Fund

ceasing to qualify as a regulated investment company under the Internal Revenue Code of 1986, as amended (the “Code”).

Any decline in the NAV of the Fund’s investments would be borne entirely by the holders of common stock. Therefore, if the market value of the Fund’s portfolio declines, the leverage will result in a greater decrease in NAV to the holders of common stock than if the Fund were not leveraged. This greater NAV decrease will also tend to cause a greater decline in the market price for the common stock. The Fund might be in danger of failing to maintain the required asset coverage of the preferred stock or of losing its ratings on the preferred stock or, in an extreme case, the Fund’s current investment income might not be sufficient to meet the dividend requirements on the preferred stock. In order to counteract such an event, the Fund might need to liquidate investments in order to fund a redemption of some or all of the preferred stock.

In addition, the Fund would pay (and the holders of common stock will bear) all costs and expenses relating to the issuance and ongoing maintenance of the preferred stock, including the advisory fees on the incremental assets attributable to such shares.

Holders of preferred stock may have different interests than holders of common stock and may at times have disproportionate influence over the Fund’s affairs. Holders of preferred stock, voting together as a separate class, will have the right to elect two members of the Board at all times and in the event dividends become two full years in arrears will have the right to elect a majority of the Directors until such arrearage is completely eliminated. In addition, preferred stockholders have class voting rights on certain matters, including changes in fundamental investment restrictions and conversion of the Fund to open-end status, and accordingly can veto any such changes.

Restrictions imposed on the declarations and payment of dividends or other distributions to the holders of the Fund’s common stock and preferred stock, both by the 1940 Act and by requirements imposed by rating agencies, might impair the Fund’s ability to maintain its qualification as a regulated investment company for federal income tax purposes. While the Fund intends to redeem its preferred stock to the extent necessary to enable the Fund to distribute its income as required to maintain its qualification as a regulated investment company under the Code, there can be no assurance that such actions can be effected in time to meet the Code requirements.

Special Risks to Holders of Fixed Rate Preferred Stock

Market Price Fluctuation. Shares of Fixed Rate Preferred Stock that are listed on a national securities exchange may trade at a premium to or discount from liquidation value for various reasons, including changes in interest rates.

Common Stock Repurchases. Repurchases of common stock by the Fund may reduce the net asset coverage of the preferred stock, which could adversely affect their liquidity or market prices, if such preferred shares are listed on a national securities exchange.

Common Stock Distribution Policy. In the event the Fund does not generate a total return from dividends and interest received and net realized capital gains in an amount at least equal to its distributions for a given year, the Fund may return capital as part of its distribution. This would decrease the asset coverage per share with respect to the Fund’s preferred stock, which could adversely affect its liquidity or market prices, if such preferred

shares are listed on a national securities exchange. See “Risk Factors and Special Considerations —Common Stock Distribution Policy Risk.”

Credit Quality Ratings. The Fund may obtain credit quality ratings for its preferred stock, if desired; however, it is not required to do so and may issue shares of preferred stock without any rating. If rated, the Fund does not impose any minimum rating necessary to issue such shares. In order to obtain and maintain attractive credit quality ratings for preferred stock or borrowings, if desired, the Fund’s portfolio must satisfy over-collateralization tests established by the relevant rating agencies. These tests are more difficult to satisfy to the extent the Fund’s portfolio securities are of lower credit quality, longer maturity or not diversified by issuer and industry within the meaning of such rating agencies’ over-collateralization tests. These guidelines could affect portfolio decisions and may be more stringent than those imposed by the 1940 Act. With respect to ratings (if any) of the preferred stock, a rating by a ratings agency does not eliminate or necessarily mitigate the risks of investing in our preferred stock, and a rating may not fully or accurately reflect all of the securities’ credit risks. A rating does not address the liquidity or any other market risks of the securities being rated. A rating agency could downgrade the rating of our preferred stock, which may make such securities less liquid in the secondary market. If a rating agency downgrades the rating assigned to our preferred stock, we may alter our portfolio or redeem all or a portion of the preferred stock that are then redeemable under certain circumstances.

●

Portfolio Guidelines of Rating Agencies for Preferred Stock and/or Credit Facility. In order to obtain and maintain attractive credit quality ratings for preferred stock, if desired, the Fund must comply with investment quality, diversification and other guidelines established by the relevant rating agencies. These tests tend to require over-collateralization and may be more difficult to satisfy to the extent the Fund’s portfolio securities are of lower credit quality, longer maturity or not diversified by issuer and industry within the meaning of such rating agencies’ collateralization tests. These guidelines could affect portfolio decisions and may be more stringent than those imposed by the 1940 Act. In the event that a rating on the Fund’s preferred stock is lowered or withdrawn by the relevant rating agency, the Fund may also be required to redeem all or part of its outstanding preferred stock, and the common stock of the Fund will lose the potential benefits associated with a leveraged capital structure.

●

Impact on Common Stock. Assuming that leverage will (1) be equal in amount to approximately 22% of the Fund’s total net assets, and (2) charge interest or involve dividend payments at a projected blended annual average leverage dividend or interest rate of 5.42%, then the annual return generated by the Fund’s portfolio (net of estimated expenses) must exceed approximately 1.20% of the Fund’s total net assets in order to cover such interest or dividend payments and other expenses specifically related to leverage. These numbers are merely estimates, used for illustration. Actual dividend rates, interest or payment rates may vary frequently and may be significantly higher or lower than the rate estimated above. The following table is furnished in response to requirements of the SEC. It is designed to illustrate the effect of leverage on common stock total return, assuming investment portfolio total returns (comprised of net investment income of the Fund, realized gains or losses of the Fund and changes in the value of the securities held in the Fund’s portfolio) of -10%, -5%, 0%, 5% and 10%. These assumed investment portfolio returns are hypothetical figures and are not necessarily indicative of the investment portfolio returns experienced or expected to be experienced by the Fund. See “Risks.” The table further reflects leverage representing 22% of the Fund’s net assets, the Fund’s current projected blended annual average leverage dividend or interest rate of 5.42%, a management fee at an annual rate of 1.00%

of the liquidation preference of any outstanding preferred stock and estimated annual incremental expenses attributable to any outstanding preferred stock of 0.01% of the Fund’s net assets attributable to shares of common stock.

Assumed Portfolio Total Return (Net of Expenses)	(10.00)%	(5.00)%	0.00%	5.00%	10.00%
Common Stock Total Return	(14.63)%	(8.22)%	(1.81)%	4.60%	11.01%

Common stock total return is composed of two elements — the common share distributions paid by the Fund (the amount of which is largely determined by the taxable income of the Fund (including realized gains or losses) after paying interest on any debt and/or dividends on any preferred stock) and unrealized gains or losses on the value of the securities the Fund owns. As required by SEC rules, the table assumes that the Fund is more likely to suffer capital losses than to enjoy total return. For example, to assume a total return of 0% the Fund must assume that the income it receives on its investments is entirely offset by expenses and losses in the value of those investments.

Special Risks for Holders of Subscription Rights

There is a risk that changes in yield or changes in the credit quality of the Fund may result in the underlying preferred stock or common stock purchasable upon exercise of the subscription rights being less attractive to investors at the conclusion of the subscription period. This may reduce or eliminate the value of the subscription rights. Investors who receive subscription rights may find that there is no market to sell rights they do not wish to exercise. If investors exercise only a portion of the rights, the number of shares of preferred stock or common stock issued may be reduced, and the preferred stock or common stock may trade at less favorable prices than larger offerings for similar securities.

Common Stock Distribution Policy Risk

The Fund has adopted a policy, which may be changed at any time by the Board, of paying a minimum annual distribution of 10% of the average NAV of the Fund to common stockholders. In the event the Fund does not generate a total return from dividends and interest received and net realized capital gains in an amount equal to or in excess of its stated distribution in a given year, the Fund may return capital as part of such distribution, which may have the effect of decreasing the asset coverage per share with respect to the Fund’s preferred stock. Any return of capital should not be considered by investors as yield or total return on their investment in the Fund. For the fiscal year ended December 31, 2022, the Fund made distributions of $0.60 per share of common stock, of which $0.31 per share was deemed return of capital. The Fund has made quarterly distributions with respect to its common stock since 1987. A portion of the distributions to common stockholders during 23 of the 35 fiscal years that distributions were paid since the Fund’s inception has constituted a return of capital. The composition of each distribution is estimated based on the earnings of the Fund as of the record date for each distribution. The actual composition of each of the current year’s distributions will be based on the Fund’s investment activity through the end of the calendar year.

Value Investing Risk

The Fund invests in dividend-paying common and preferred stocks that the Investment Adviser believes are undervalued or inexpensive relative to other investments. These types of securities may present risks in addition

to the general risks associated with investing in common and preferred stocks. These securities generally are selected on the basis of an issuer’s fundamentals relative to current market price. Such securities are subject to the risk of mis-estimation of certain fundamental factors. In addition, during certain time periods market dynamics may strongly favor “growth” stocks of issuers that do not display strong fundamentals relative to market price based upon positive price momentum and other factors. Disciplined adherence to a “value” investment mandate during such periods can result in significant underperformance relative to overall market indices and other managed investment vehicles that pursue growth style investments and/or flexible equity style mandates.

Non-Diversified Status

The Fund is classified as a “non-diversified” investment company under the 1940 Act, which means it is not limited by the 1940 Act in the proportion of its assets that may be invested in the securities of a single issuer. As a non-diversified investment company, the Fund may invest in the securities of individual issuers to a greater degree than a diversified investment company. As a result, the Fund may be more vulnerable to events affecting a single issuer and therefore subject to greater volatility than a fund that is more broadly diversified. Accordingly, an investment in the Fund may present greater risk to an investor than an investment in a diversified company. To qualify as a “regulated investment company,” or “RIC,” for purposes of the Code, the Fund has in the past conducted and intends to conduct its operations in a manner that will relieve it of any liability for federal income tax to the extent its earnings are distributed to stockholders. To so qualify as a “regulated investment company,” among other requirements, the Fund will limit its investments so that, at the close of each quarter of the taxable year:

●

not more than 25% of the market value of its total assets will be invested in the securities (other than United States government securities or the securities of other RICs) of a single issuer, any two or more issuers in which the Fund owns 20% or more of the voting securities and which are determined to be engaged in the same, similar or related trades or businesses or in the securities of one or more qualified publicly traded partnerships (as defined in the Code); and

●

at least 50% of the market value of the Fund’s assets will be represented by cash, securities of other RICs, United States government securities and other securities, with such other securities limited in respect of any one issuer to an amount not greater than 5% of the value of its assets and not more than 10% of the outstanding voting securities of such issuer.

Market Value and Net Asset Value

The Fund is a non-diversified, closed-end management investment company. Shares of closed-end funds are bought and sold in the securities markets and may trade at either a premium to or discount from NAV. Listed shares of closed-end investment companies often trade at discounts from NAV. This characteristic of shares of a closed-end fund is a risk separate and distinct from the risk that its NAV may decrease. The Fund cannot predict whether its listed stock will trade at, below or above NAV. Since inception, the Fund’s shares of common stock have traded at both premiums to and discounts from NAV. As of December 31, 2022, the market price of the Fund closed at an approximate 7.87% premium to its NAV. Stockholders desiring liquidity may, subject to applicable securities laws, trade their Fund shares on the NYSE or other markets on which such shares may trade at the then-current market value, which may differ from the then-current NAV. Stockholders will incur brokerage or other transaction costs to sell stock.

Equity Risk

Investing in the Fund involves equity risk, which is the risk that the securities held by the Fund will fall in market value due to adverse market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate and the particular circumstances and performance of particular companies whose securities the Fund holds. An investment in the Fund represents an indirect economic stake in the securities owned by the Fund, which are for the most part traded on securities exchanges or in the OTC markets. The market value of these securities, like other market investments, may move up or down, sometimes rapidly and unpredictably. The NAV of the Fund may at any point in time be worth less than the amount at the time the stockholder invested in the Fund, even after taking into account any reinvestment of distributions.

Industry Risk

The Fund may invest up to 25% of its total assets in securities of a single industry. Should the Fund choose to do so, the NAV of the Fund will be more susceptible to factors affecting those particular types of companies, which, depending on the particular industry, may include, among others: governmental regulation; inflation; cost increases in raw materials, fuel and other operating expenses; technological innovations that may render existing products and equipment obsolete; and increasing interest rates resulting in high interest costs on borrowings needed for capital investment, including costs associated with compliance with environmental and other regulations. In such circumstances, the Fund’s investments may be subject to greater risk and market fluctuation than a fund that had securities representing a broader range of industries.

Special Risks Related to Fund Investments in Preferred Securities

There are special risks associated with the Fund’s investing in preferred securities, including:

●

Deferral. Preferred securities may include provisions that permit the issuer, at its discretion, to defer dividends or distributions for a stated period without any adverse consequences to the issuer. If the Fund owns a preferred security that is deferring its dividends or distributions, the Fund may be required to report income for tax purposes although it has not yet received such income.

●

Non-Cumulative Dividends. Some preferred securities are non-cumulative, meaning that the dividends do not accumulate and need not ever be paid. A portion of the portfolio may include investments in non-cumulative preferred securities, whereby the issuer does not have an obligation to make up any arrearages to its stockholder. Should an issuer of a non-cumulative preferred security held by the Fund determine not to pay dividends or distributions on such security, the Fund’s return from that security may be adversely affected. There is no assurance that dividends or distributions on non-cumulative preferred securities in which the Fund invests will be declared or otherwise made payable.

●

Subordination. Preferred securities are subordinated to bonds and other debt instruments in an issuer’s capital structure in terms of priority to corporate income and liquidation payments, and therefore will be subject to greater credit risk than more senior debt security instruments.

●

Liquidity. Preferred securities may be substantially less liquid than many other securities, such as common stocks or U.S. government securities.

●

Limited Voting Rights. Generally, preferred security holders (such as the Fund) have no voting rights with respect to the issuing company unless preferred dividends have been in arrears for a specified number of periods, at which time the preferred security holders may be entitled to elect a number of directors to the issuer’s board. Generally, once all the arrearages have been paid, the preferred security holders no longer have voting rights.

●

Special Redemption Rights. In certain varying circumstances, an issuer of preferred securities may redeem the securities prior to a specified date. For instance, for certain types of preferred securities, a redemption may be triggered by a change in federal income tax or securities laws. A redemption by the issuer may negatively impact the return of the security held by the Fund.

●

Phantom Income. Some preferred securities are classified as debt for U.S. federal income tax purposes. If a debt instrument is issued with original issue discount, the Fund could recognize taxable income in advance of the receipt of cash on the investment. This “phantom income” may require the Fund to liquidate other investments (including when it is not advantageous to do so) to meet its distribution requirements or otherwise qualify for treatment as a RIC.

Coronavirus (“COVID-19”) and Global Health Event Risk

As of the date of this annual report, there is an outbreak of a highly contagious form of a novel coronavirus known as “COVID 19.” COVID 19 has been declared a pandemic by the World Health Organization and, in response to the outbreak, the U.S. Health and Human Services Secretary has declared a public health emergency in the United States. COVID 19 had a devastating impact on the global economy, including the U.S. economy, and resulted in a global economic recession. Many states issued orders requiring the closure of non essential businesses and/ or requiring residents to stay at home. The COVID 19 pandemic and preventative measures taken to contain or mitigate its spread have caused, and are continuing to cause, business shutdowns, cancellations of events and travel, significant reductions in demand for certain goods and services, reductions in business activity and financial transactions, supply chain interruptions and overall economic and financial market instability both globally and in the United States. Such effects will likely continue for the duration of the pandemic, which is uncertain, and for some period thereafter. While several countries, as well as certain states, counties, and cities in the United States, began to relax the early public health restrictions with a view to partially or fully reopening their economies, many cities, both globally and in the United States, continue to experience, from time to time, surges in the reported number of cases and hospitalizations related to the COVID 19 pandemic. Recurring COVID 19 outbreaks, newly discovered variant and sub variant strains of the virus and increases in cases can, and has, led to the re introduction of restrictions and business shutdowns in certain states, counties, and cities in the United States and globally, and could continue to lead to the re introduction of such restrictions elsewhere. Even after the COVID 19 pandemic subsides, the U.S. economy and most other major global economies may continue to experience a substantial economic downturn or recession, and our business and operations, as well as the business and operations of our portfolio companies, could be materially adversely affected by a prolonged economic downturn or recession in the United States and other major markets.

The current economic situation and the unprecedented measures taken by state, local and national governments around the world to combat the spread of COVID 19, as well as various social, political and psychological tensions in the United States and around the world, may continue to contribute to severe market disruptions and volatility and reduced economic activity, may have long-term negative effects on the U.S. and worldwide financial

markets and economy and may cause further economic uncertainties in the United States and worldwide. The prolonged continuation or further deterioration of the current U.S. and global economic downturn could adversely impact the Fund’s portfolio. It is difficult to predict how long the financial markets and economic activity will continue to be impacted by these events and the Fund cannot predict the effects of these or similar events in the future on the U.S. economy and securities markets.

Despite actions of the U.S. federal government and foreign governments, the uncertainty surrounding the COVID 19 pandemic and other factors has contributed to significant volatility in the global public equity markets and global debt capital markets, including the NAV of the Fund’s shares. These events could have, and/or have had, a significant impact on the Fund’s performance, NAV, income, operating results and ability to pay distributions, as well as the performance, income, operating results and viability of issuers in which it invests.

It is virtually impossible to determine the ultimate impact of COVID 19 at this time. Further, the extent and strength of any economic recovery after the COVID 19 pandemic abates, including following any intensifying of the pandemic, is uncertain and subject to various factors and conditions. Accordingly, an investment in the Fund is subject to an elevated degree of risk as compared to other market environments.

Market Disruption and Geopolitical Risk

The consequences of the conflict between Russia and Ukraine, including international sanctions, further impact on inflation and increased disruption to supply chains may impact our portfolio companies, result in an economic downturn or recession either globally or locally in the U.S. or other economies, reduce business activity, spawn additional conflicts (whether in the form of traditional military action, reignited “cold” wars or in the form of virtual warfare such as cyberattacks) with similar and perhaps wider ranging impacts and consequences and have an adverse impact on the Fund’s returns and NAV.

The occurrence of events similar to those in recent years, such as localized wars, instability, new and ongoing pandemics (such as COVID-19), epidemics or outbreaks of infectious diseases in certain parts of the world, natural/environmental disasters, terrorist attacks in the United States and around the world, social and political discord, debt crises sovereign debt downgrades, increasingly strained relations between the United States and a number of foreign countries, new and continued political unrest in various countries, the exit or potential exit of one or more countries from the European Union (“EU”) or the Economic and Monetary Union, continued changes in the balance of political power among and within the branches of the U.S. government, government shutdowns, among others, may result in market volatility, may have long term effects on the U.S. and worldwide financial markets, and may cause further economic uncertainties in the United States and worldwide. The current contentious domestic political environment, as well as political and diplomatic events within the United States and abroad, such as the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan, may in the future result in government shutdowns, which could have a material adverse effect on the Fund’s investments and operations. In addition, the Fund’s ability to raise additional capital in the future through the sale of securities could be materially affected by a government shutdown. Additional and/ or prolonged U.S. government shutdowns may affect investor and consumer confidence and may adversely impact financial markets and the broader economy, perhaps suddenly and to a significant degree. In particular, the escalation of the conflict between Russia and Ukraine, including international sanctions, further impact on inflation and increased disruption to supply chains may impact our portfolio companies. Such unfavorable

economic conditions also may also be expected to increase our funding costs, limit our access to the capital markets or result in a decision by lenders not to extend credit to us. The current political climate has intensified concerns about a potential trade war between China and the United States, as each country has recently imposed tariffs on the other country’s products. These actions may trigger a significant reduction in international trade, the oversupply of certain manufactured goods, substantial price reductions of goods and possible failure of individual companies and/or large segments of China’s export industry, which could have a negative impact on our performance. U.S. companies that source material and goods from China and those that make large amounts of sales in China would be particularly vulnerable to an escalation of trade tensions. Uncertainty regarding the outcome of the trade tensions and the potential for a trade war could cause the U.S. dollar to decline against safe haven currencies, such as the Japanese yen and the euro. Events such as these and their consequences are difficult to predict and it is unclear whether further tariffs may be imposed or other escalating actions may be taken in the future. Any of these effects could have a material adverse effect on our business, financial condition and results of operations.

On January 31, 2020, the United Kingdom (“UK”) officially withdrew from the EU (commonly known as “Brexit”). The UK and EU reached a preliminary trade agreement, which became effective on January 1, 2021, regarding the terms of their future trading relationship relating principally to the trading of goods; however, negotiations are ongoing for matters not covered by the agreement, such as the trade of financial services. Due to uncertainty of the current political environment, it is not possible to foresee the form or nature of the future trading relationship between the UK and the EU. The longer term economic, legal, political and social framework to be put in place between the UK and the EU remains unclear and the ongoing political and economic uncertainty and periods of exacerbated volatility in both the UK and in wider European markets may continue for some time. In particular, Brexit may lead to a call for similar referendums in other European jurisdictions which may cause increased economic volatility in the European and global markets and may destabilize some or all of the other EU member countries. This uncertainty may have an adverse effect on the economy generally and on the ability of the Fund and its investments to execute their respective strategies, to receive attractive returns and/or to exit certain investments at an advantageous time or price. In particular, currency volatility may mean that the returns of the Fund and its investments are adversely affected by market movements and may make it more difficult, or more expensive, if the Fund elects to execute currency hedges. Potential decline in the value of the British Pound and/or the Euro against other currencies, along with the potential downgrading of the UK’s sovereign credit rating, may also have an impact on the performance of portfolio companies or investments located in the UK or Europe. In light of the above, no definitive assessment can currently be made regarding the impact that Brexit will have on the Fund, its investments or its organization more generally.

While the extreme volatility and disruption that U.S. and global markets experienced for an extended period of time beginning in 2007 and 2008 had, until the recent coronavirus (COVID-19) outbreak, generally subsided, uncertainty and periods of volatility still remain, and risks to a robust resumption of growth persist. Federal Reserve policy, including with respect to certain interest rates, may adversely affect the value, volatility and liquidity of dividend and interest paying securities. Market volatility, dramatic changes to interest rates and/or a return to unfavorable economic conditions may lower the Fund’s performance or impair the Fund’s ability to achieve its investment objective.

Cybersecurity incidents affecting particular companies or industries may adversely affect the economies of particular countries, regions or parts of the work in which the Fund invests.

The occurrence of any of these above events could have a significant adverse impact on the value and risk profile of the Fund’s portfolio. The Fund does not know how long the securities markets may be affected by similar events and cannot predict the effects of similar events in the future on the U.S. economy and securities markets. There can be no assurance that similar events and other market disruptions will not have other material and adverse implications.

Economic Events and Market Risk

Periods of market volatility may continue to occur in the future, in response to various political, social and economic events both within and outside of the United States. These conditions have resulted in, and in many cases continue to result in, greater price volatility, less liquidity, widening credit spreads and a lack of price transparency, with many securities remaining illiquid and of uncertain value. Such market conditions may adversely affect the Fund, including by making valuation of some of the Fund’s securities uncertain and/or result in sudden and significant valuation increases or declines in the Fund’s holdings. If there is a significant decline in the value of the Fund’s portfolio, this may impact the asset coverage levels for the Fund’s outstanding leverage.

Risks resulting from any future debt or other economic crisis could also have a detrimental impact on the global economic recovery, the financial condition of financial institutions and our business, financial condition and results of operation. Market and economic disruptions have affected, and may in the future affect, consumer confidence levels and spending, personal bankruptcy rates, levels of incurrence and default on consumer debt and home prices, among other factors. To the extent uncertainty regarding the U.S. or global economy negatively impacts consumer confidence and consumer credit factors, our business, financial condition and results of operations could be significantly and adversely affected. Downgrades to the credit ratings of major banks could result in increased borrowing costs for such banks and negatively affect the broader economy. Moreover, Federal Reserve policy, including with respect to certain interest rates, may also adversely affect the value, volatility and liquidity of dividend- and interest-paying securities. Market volatility, rising interest rates and/ or a return to unfavorable economic conditions could impair the Fund’s ability to achieve its investment objective.

Regulation and Government Intervention Risk

Federal, state, and other governments, their regulatory agencies or self-regulatory organizations may take actions that affect the regulation of the issuers in which the Fund invests in ways that are unforeseeable. Legislation or regulation may also change the way in which the Fund is regulated. Such legislation or regulation could limit or preclude the Fund’s ability to achieve its investment objective.

In light of popular, political and judicial focus on finance related consumer protection. Financial institution practices are also subject to greater scrutiny and criticism generally. In the case of transactions between financial institutions and the general public, there may be a greater tendency toward strict interpretation of terms and legal rights in favor of the consuming public, particularly where there is a real or perceived disparity in risk allocation and/or where consumers are perceived as not having had an opportunity to exercise informed consent to the transaction. In the event of conflicting interests between retail investors holding common shares

of a closed-end investment company such as the Fund and a large financial institution, a court may similarly seek to strictly interpret terms and legal rights in favor of retail investors.

The Fund may be affected by governmental action in ways that are not foreseeable, and there is a possibility that such actions could have a significant adverse effect on the Fund and its ability to achieve its investment objective.

Inflation Risk

Inflation risk is the risk that the value of assets or income from investments will be worth less in the future as inflation decreases the value of money. Inflation rates may change frequently and drastically as a result of various factors, including unexpected shifts in the domestic or global economy. As inflation increases, the real value of the Fund’s shares and distributions therefore may decline. In addition, during any periods of rising inflation, dividend rates of any debt securities issued by the Fund would likely increase, which would tend to further reduce returns to the Fund’s common stockholders.

Deflation Risk

Deflation risk is the risk that prices throughout the economy decline over time, which may have an adverse effect on the market valuation of companies, their assets and their revenues. In addition, deflation may have an adverse effect on the creditworthiness of issuers and may make issuer default more likely, which may result in a decline in the value of the Fund’s portfolio.

Interest Rate Transactions

The Fund may enter into interest rate swap or cap transactions. The use of interest rate swaps and caps is a highly specialized activity that involves certain risks to the Fund including, among others, counterparty risk and early termination risk.

Foreign Securities

The Fund may invest up to 35% of its total assets in securities of foreign issuers, including emerging market issuers, determined at the time of purchase. Investments in the securities of foreign issuers involve certain considerations and risks not ordinarily associated with investments in securities of domestic issuers and such securities may be more volatile than those of issuers in the United States. Foreign companies are not generally subject to uniform accounting, auditing and financial standards, and requirements comparable to those applicable to United States companies. Foreign securities exchanges, brokers and listed companies may be subject to less government supervision and regulation than exists in the United States. Dividend and interest income may be subject to withholding and other foreign taxes, which may adversely affect the net return on such investments. There may be difficulty in obtaining or enforcing a court judgment abroad. In addition, it may be difficult to effect repatriation of capital invested in certain countries. Also, with respect to certain countries, there are risks of expropriation, confiscatory taxation, political or social instability or diplomatic developments that could affect assets of the Fund held in foreign countries. Dividend income that the Fund receives from foreign securities may not be eligible for the special tax treatment applicable to qualified dividend income. Moreover, certain equity investments in foreign issuers classified as passive foreign investment companies may be subject to additional taxation risk.

There may be less publicly available information about a foreign company than a United States company. Foreign securities markets may have substantially less volume than United States securities markets and some foreign company securities are less liquid than securities of otherwise comparable United States companies. A portfolio of foreign securities may also be adversely affected by fluctuations in the rates of exchange between the currencies of different nations and by exchange control regulations. Foreign markets also have different clearance and settlement procedures that could cause the Fund to encounter difficulties in purchasing and selling securities on such markets and may result in the Fund missing attractive investment opportunities or experiencing loss. In addition, a portfolio that includes foreign securities can expect to have a higher expense ratio because of the increased transaction costs on non-United States securities markets and the increased costs of maintaining the custody of foreign securities.

The Fund also may purchase sponsored American Depositary Receipts (“ADRs”) or United States dollar denominated securities of foreign issuers, including emerging market issuers. ADRs are receipts issued by United States banks or trust companies in respect of securities of foreign issuers held on deposit for use in the United States securities markets. While ADRs may not necessarily be denominated in the same currency as the securities into which they may be converted, many of the risks associated with foreign securities may also apply to ADRs. In addition, the underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute stockholder communications to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited securities.

Emerging Markets

The Fund may invest up to 35% of its total assets in foreign securities, including securities of issuers whose primary operations or principal trading market is in an “emerging market.” An “emerging market” country is any country that is considered to be an emerging or developing country by the International Bank for Reconstruction and Development (the “World Bank”). Investing in securities of companies in emerging markets may entail special risks relating to potential political and economic instability and the risks of expropriation, nationalization, confiscation or the imposition of restrictions on foreign investment, the lack of hedging instruments and restrictions on repatriation of capital invested. Emerging securities markets are substantially smaller, less developed, less liquid and more volatile than the major securities markets. The limited size of emerging securities markets and limited trading value compared to the volume of trading in U.S. securities could cause prices to be erratic for reasons apart from factors that affect the quality of the securities. For example, limited market size may cause prices to be unduly influenced by traders who control large positions. Adverse publicity and investors’ perceptions, whether or not based on fundamental analysis, may decrease the value and liquidity of portfolio securities, especially in these markets. Other risks include high concentration of market capitalization and trading volume in a small number of issuers representing a limited number of industries, as well as a high concentration of investors and financial intermediaries; overdependence on exports, including gold and natural resources exports, making these economies vulnerable to changes in commodity prices; overburdened infrastructure and obsolete or unseasoned financial systems; environmental problems; potential for sanctions; less developed legal systems, and deficiencies in regulatory oversight, market infrastructure, shareholder protections; differences in regulatory, accounting, auditing and financial reporting and recordkeeping standards; and less reliable securities custodial services and settlement practices.

Smaller Companies

The Fund may invest in smaller companies that may benefit from the development of new products and services. These smaller companies may present greater opportunities for capital appreciation, and may also involve greater investment risk than larger, more established companies. For example, smaller companies may have more limited product lines, market or financial resources and their securities may trade less frequently and in lower volume than the securities of larger, more established companies. As a result, the prices of the securities of such smaller companies may fluctuate to a greater degree than the prices of securities of other issuers.

Investment Companies

The Fund may invest in the securities of other investment companies to the extent permitted by law. To the extent the Fund invests in the common equity of investment companies, the Fund will bear its ratable share of any such investment company’s expenses, including management fees. The Fund will also remain obligated to pay management fees to the Investment Adviser with respect to the assets invested in the securities of other investment companies. In these circumstances holders of the Fund’s common stock will be subject to duplicative investment expenses.

Fixed Income Securities

FixFixed income securities in which the Fund may invest are generally subject to the following risks:

●

Interest Rate Risk. The market value of bonds and other fixed-income or dividend paying securities changes in response to interest rate changes and other factors. Interest rate risk is the risk that prices of bonds and other income or dividend paying securities will increase as interest rates fall and decrease as interest rates rise. The Fund may be subject to a greater risk of rising interest rates due to the recent period of historically low interest rates. The Federal Reserve has recently begun to raise the federal funds rate as part of its efforts to address rising inflation. There is a risk that interest rates will continue to rise, which will likely drive down prices of bonds and other fixed-income securities. The magnitude of these price reductions in the market price of bonds and other fixed-income securities is generally greater for those securities with longer maturities. Fluctuations in the market price of the Fund’s investments will not affect interest income derived from instruments already owned by the Fund, but will be reflected in the Fund’s NAV. The Fund may lose money if short-term or long-term interest rates rise sharply in a manner not anticipated by the Investment Adviser.

●

Issuer Risk. Issuer risk is the risk that the value of an income or dividend paying security may decline for a number of reasons which directly relate to the issuer, such as management performance, financial leverage, reduced demand for the issuer’s goods and services, historical and prospective earnings of the issuer, and the value of the assets of the issuer.

●

Credit Risk. Credit risk is the risk that one or more income or dividend paying securities in the Fund’s portfolio will decline in price or fail to pay interest/distributions or principal when due because the issuer of the security experiences a decline in its financial status. Credit risk is increased when a portfolio security is downgraded or the perceived creditworthiness of the issuer deteriorates.

●

Prepayment Risk. Prepayment risk is the risk that during periods of declining interest rates, borrowers may exercise their option to prepay principal earlier than scheduled. For income or dividend paying securities, such payments often occur during periods of declining interest rates, forcing the Fund to re-

invest in lower yielding securities, resulting in a possible decline in the Fund’s income and distributions to shareholders.

●

Reinvestment Risk. Reinvestment risk is the risk that income from the Fund’s portfolio will decline if the Fund invests the proceeds from matured, traded or called fixed income securities at market interest rates that are below the Fund portfolio’s current earnings rate.

●

Duration and Maturity Risk. The Fund may incur costs in seeking to adjust the portfolio average duration or maturity. In comparison to maturity (which is the date on which the issuer of a debt instrument is obligated to repay the principal amount), duration is a measure of the price volatility of a debt instrument as a result in changes in market rates of interest, based on the weighted average timing of the instrument’s expected principal and interest payments. Specifically, duration measures the anticipated percentage change in NAV that is expected for every percentage point change in interest rates. The two have an inverse relationship. For example, a duration of five years means that a 1% decrease in interest rates will increase the NAV of the portfolio by approximately 5%; if interest rates increase by 1%, the NAV will decrease by 5%. However, in a managed portfolio of fixed income securities having differing interest or dividend rates or payment schedules, maturities, redemption provisions, call or prepayment provisions and credit qualities, actual price changes in response to changes in interest rates may differ significantly from a duration-based estimate at any given time. Actual price movements experienced by a portfolio of fixed income securities will be affected by how interest rates move (i.e., changes in the relationship of long term interest rates to short term interest rates), the magnitude of any move in interest rates, actual and anticipated prepayments of principal through call or redemption features, the extension of maturities through restructuring, the sale of securities for portfolio management purposes, the reinvestment of proceeds from prepayments on and from sales of securities, and credit quality-related considerations whether associated with financing costs to lower credit quality borrowers or otherwise, as well as other factors. Accordingly, while duration maybe a useful tool to estimate potential price movements in relation to changes in interest rates, investors are cautioned that duration alone will not predict actual changes in the net asset or market value of the Fund’s shares and that actual price movements in the Fund’s portfolio may differ significantly from duration-based estimates. Duration differs from maturity in that it takes into account a security’s yield, coupon payments and its principal payments in addition to the amount of time until the security matures. As the value of a security changes over time, so will its duration. There can be no assurance that the Investment Adviser’s assessment of current and projected market conditions will be correct or that any strategy to adjust duration or maturity will be successful at any given time.

●

Liquidity Risk. Certain fixed income securities in which the Fund invests may be or become illiquid.

LIBOR Risk

The Fund may be exposed to financial instruments that are tied to the London Interbank Offered Rate (“LIBOR”) to determine payment obligations, financing terms, hedging strategies or investment value. The Fund may

also obtain financing at floating rates based on LIBOR. Derivative instruments utilized by the Fund may also reference LIBOR.

The United Kingdom’s Financial Conduct Authority announced a phase out of LIBOR such that after June 30, 2023, the overnight, 1-month, 3-month, 6-month and 12-month U.S. dollar LIBOR settings will cease to be published or will no longer be representative. All other LIBOR settings and certain other interbank offered rates, such as the Euro Overnight Index Average (“EONIA”), ceased to be published or representative after December 31, 2021. The Fund may have investments linked to other interbank offered rates that may also cease to be published in the future. Various financial industry groups have been planning for the transition away from LIBOR, but there remain challenges to converting certain securities and transactions to a new reference rate (e.g., the Secured Overnight Financing Rate (“SOFR”), which is intended to replace the U.S. dollar LIBOR).

There is currently no definitive information regarding the future utilization of LIBOR or of any particular replacement rate. Abandonment of or modifications to LIBOR could lead to significant short-term and long-term uncertainty and market instability.

The market transition away from LIBOR and other current reference rates to alternative reference rates is complex and could have a range of adverse impacts on the Fund’s investment program, financial condition and results of operations. Among other negative consequences, this transition could:

●

Adversely impact the pricing, liquidity, value of, return on and trading for a broad array of financial products, including any LIBOR-linked securities, loans and derivatives in which the Fund may invest;

●

Require extensive negotiations of and/or amendments to agreements and other documentation governing LIBOR-linked investments products;

●

Lead to disputes, litigation or other actions with counterparties or portfolio companies regarding the interpretation and enforceability of “fall back” provisions that provide for an alternative reference rate in the event of LIBOR’s unavailability; and

●

Cause the Fund to incur additional costs in relation to any of the above factors.

The risks associated with the above factors are heightened with respect to investments in LIBOR-based products that do not include a fall back provision that addresses how interest rates will be determined if LIBOR stops being published. There remains uncertainty regarding the willingness and ability of issuers to add alternative rate-setting provisions in certain existing instruments. Global regulators have advised market participants to cease entering into new contracts using LIBOR as a reference rate, and it is possible that investments in LIBOR-based instruments could invite regulatory scrutiny. Other important factors include the pace of the transition, the specific terms of alternative reference rates accepted in the market, the depth of the market for investments based on alternative reference rates, and the Investment Adviser’s ability to develop appropriate investment and compliance systems capable of addressing alternative reference rates.

Non-Investment Grade Securities

The Fund may invest up to 10% of its total assets in fixed income securities rated below investment grade by recognized statistical rating agencies or unrated securities of comparable quality. These securities, which may be preferred stock or debt, are predominantly speculative and involve major risk exposure to adverse conditions. Debt securities that are not rated or that are rated lower than “BBB” by S&P or lower than “Baa” by Moody’s are

referred to in the financial press as “junk bonds.” Such securities are subject to greater risks than investment grade securities, which reflect their speculative character, including the following:

●

greater volatility;

●

greater credit risk;

●

potentially greater sensitivity to general economic or industry conditions;

●

potential lack of attractive resale opportunities (illiquidity); and

●

additional expenses to seek recovery from issuers who default.

Fixed income securities purchased by the Fund may be rated as low as C by Moody’s or D by S&P or may be unrated securities considered to be of equivalent quality. Securities that are rated C by Moody’s are the lowest rated class and can be regarded as having extremely poor prospects of ever obtaining investment-grade standing. Debt rated D by S&P is in default or is expected to default upon maturity of payment date.

The market value of lower rated securities may be more volatile than the market value of higher rated securities and generally tends to reflect the market’s perception of the creditworthiness of the issuer and short term market developments to a greater extent than more highly rated securities, which primarily reflect fluctuations in general levels of interest rates. Generally, such non-investment grade securities and unrated securities of comparable quality offer a higher current yield than is offered by higher rated securities, but also (i) will likely have some quality and protective characteristics that, in the judgment of the rating organizations, are outweighed by large uncertainties or major risk exposures to adverse conditions and (ii) are predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal in accordance with the terms of the obligation. The market values of certain of these securities also tend to be more sensitive to individual corporate developments and changes in economic conditions than higher quality securities. In addition, such securities generally present a higher degree of credit risk. The risk of loss due to default by these issuers is significantly greater because such non-investment grade securities and unrated securities of comparable quality generally are unsecured and frequently are subordinated to the prior payment of senior indebtedness. In light of these risks, the Investment Adviser, in evaluating the creditworthiness of an issue, whether rated or unrated, will take various factors into consideration, which may include, as applicable, the issuer’s operating history, financial resources and its sensitivity to economic conditions and trends, the market support for the facility financed by the issue, the perceived ability and integrity of the issuer’s management, and regulatory matters.

Non-investment grade securities also present risks based on payment expectations. If an issuer calls the obligation for redemption (often a feature of fixed income securities), the Fund may have to replace the security with a lower yielding security, resulting in a decreased return for investors. Also, as the principal value of nonconvertible bonds and preferred stocks moves inversely with movements in interest rates, in the event of rising interest rates the value of the securities held by the Fund may decline proportionately more than a portfolio consisting of higher rated securities. Investments in zero coupon bonds may be more speculative and subject to greater fluctuations in value due to changes in interest rates than bonds that pay regular income streams. See “—Fixed Income Securities—Interest Rate Risk” above.

Ratings are relative and subjective, and are not absolute standards of quality. Securities ratings are based largely on the issuer’s historical financial condition and the rating agencies’ analysis at the time of rating.

Consequently, the rating assigned to any particular security is not necessarily a reflection of the issuer’s current financial condition.

As part of its investment in lower grade securities, the Fund may invest in securities of issuers in default. The Fund will make an investment in securities of issuers in default only when the Investment Adviser believes that such issuers will honor their obligations or emerge from bankruptcy protection under a plan pursuant to which the securities received by the Fund in exchange for its defaulted securities will have a value in excess of the Fund’s investment. By investing in securities of issuers in default, the Fund bears the risk that these issuers will not continue to honor their obligations or emerge from bankruptcy protection or that the value of the securities will not otherwise appreciate.

Special Risks of Derivative Transactions

The Fund may participate in derivative transactions. Such transactions entail certain execution, market, liquidity, hedging and tax risks. Participation in the options, futures or swaps markets and in currency exchange transactions involves investment risks and transaction costs to which the Fund would not be subject absent the use of these strategies. If the Investment Adviser’s prediction of movements in the direction of the securities, foreign currency and interest rate markets are inaccurate, the consequences to the Fund may leave the Fund in a worse position than if such strategies were not used. Risks inherent in the use of options, foreign currency, swaps contracts, futures contracts and options on futures contracts, swap contracts, securities indices and foreign currencies include:

●

dependence on the Investment Adviser’s ability to predict correctly movements in the direction of interest rates, securities prices and currency markets;

●

imperfect correlation between the price of options and futures contracts and options thereon and movements in the prices of the securities or currencies being hedged;

●

the fact that skills needed to use these strategies are different from those needed to select portfolio securities;

●

the possible absence of a liquid secondary market for any particular instrument at any time;

●

the possible need to defer closing out certain hedged positions to avoid adverse tax consequences;

●

the possible inability of the Fund to purchase or sell a security at a time that otherwise would be favorable for it to do so; and

●

the creditworthiness of counterparties.

Options, futures contracts, swaps contracts, and options thereon and forward contracts on securities and currencies may be traded on foreign exchanges. Such transactions may not be regulated as effectively as similar transactions in the United States, may not involve a clearing mechanism and related guarantees, and are subject to the risk of governmental actions affecting trading in, or the prices of, foreign securities. The value of such positions also could be adversely affected by (i) other complex foreign political, legal and economic factors, (ii) lesser availability than in the United States of data on which to make trading decisions, (iii) delays in the ability of the Fund to act upon economic events occurring in the foreign markets during non-business hours in the United States, (iv) the imposition of different exercise and settlement terms and procedures and margin requirements than in the United States and (v) less trading volume. Exchanges on which options, futures, swaps

and options on futures or swaps are traded may impose limits on the positions that the Fund may take in certain circumstances.

In October 2020, the Securities and Exchange Commission adopted new regulations governing the use of derivatives by registered investment companies (“Rule 18f-4”). The Fund will be required to implement and comply with new Rule 18f-4 by August 19, 2022. Once implemented, Rule 18f-4 will impose limits on the amount of derivatives a fund can enter into, eliminate the asset segregation framework currently used by funds to comply with Section 18 of the 1940 Act, treat derivatives as senior securities so that a failure to comply with the limits would result in a statutory violation and require funds whose use of derivatives is more than a limited specified exposure to establish and maintain a comprehensive derivatives risk management program and appoint a derivatives risk manager.

Many OTC derivatives are valued on the basis of dealers’ pricing of these instruments. However, the price at which dealers value a particular derivative and the price which the same dealers would actually be willing to pay for such derivative should the Fund wish or be forced to sell such position may be materially different. Such differences can result in an overstatement of the Fund’s NAV and may materially adversely affect the Fund in situations in which the Fund is required to sell derivative instruments. Exchange-traded derivatives and OTC derivative transactions submitted for clearing through a central counterparty have become subject to minimum initial and variation margin requirements set by the relevant clearinghouse, as well as possible margin requirements mandated by the SEC or the Commodity Futures Trading Commission. These regulators also have broad discretion to impose margin requirements on non-cleared OTC derivatives. These margin requirements will increase the overall costs for the Fund.

While hedging can reduce or eliminate losses, it can also reduce or eliminate gains. Hedges are sometimes subject to imperfect matching between the derivative and the underlying security, and there can be no assurance that the Fund’s hedging transactions will be effective.

Derivatives may give rise to a form of leverage and may expose the Fund to greater risk and increase its costs.

Under Rule 18f-4 under the 1940 Act, among other things, the Fund must either use derivatives in a limited manner or comply with an outer limit on fund leverage risk based on value-at-risk. See “—Derivatives Transactions Subject to Rule18f-4 Under the 1940 Act” below.

Derivatives Transactions Subject to Rule 18f-4 Under the 1940 Act. Rule 18f-4 under the 1940 Act governs the Fund’s use of derivative instruments and certain other transactions that create future payment and/or delivery obligations by the Fund. Rule 18f-4 permits the Fund to enter into Derivatives Transactions (as defined below) and certain other transactions notwithstanding the restrictions on the issuance of “senior securities” under Section 18 of the 1940 Act. Section 18 of the Investment Company Act, among other things, prohibits closed-end funds, including the Trust, from issuing or selling any “senior security” representing indebtedness (unless the fund maintains 300% “asset coverage”) or any senior security representing stock (unless the fund maintains 200% “asset coverage”). In connection with the adoption of Rule 18f-4, the SEC eliminated the asset segregation framework arising from prior SEC guidance for covering Derivatives Transactions and certain financial instruments.

Under Rule 18f-4, “Derivatives Transactions” include the following: (i) any swap, security-based swap (including a contract for differences), futures contract, forward contract, option (excluding purchased options), any combination of the foregoing, or any similar instrument, under which the Fund is or may be required to make any payment or delivery of cash or other assets during the life of the instrument or at maturity or early termination, whether as margin or settlement payment or otherwise; (ii) any short sale borrowing; (iii) reverse repurchase agreements and similar financing transactions, if the Fund elects to treat these transactions as Derivatives Transactions under Rule 18f-4; and (iv) when-issued or forward-settling securities (e.g., firm and standby commitments, including to-be-announced (“TBA”) commitments, and dollar rolls) and non-standard settlement cycle securities, unless the Fund intends to physically settle the transaction and the transaction will settle within 35 days of its trade date.

Unless the Fund is relying on the Limited Derivatives User Exception (as defined below), the Fund must comply with Rule 18f-4 with respect to its Derivatives Transactions. Rule 18f-4, among other things, requires the Fund to (i) appoint a Derivatives Risk Manager, (ii) maintain a Derivatives Risk Management Program designed to identify, assess, and reasonably manage the risks associated with Derivatives Transactions; (iii) comply with certain value-at-risk (VaR)-based leverage limits (VaR is an estimate of an instrument’s or portfolio’s potential losses over a given time horizon and at a specified confidence level); and (iv) comply with certain Board reporting and recordkeeping requirements.

Rule 18f-4 provides an exception from the requirements to appoint a Derivatives Risk Manager, adopt a Derivatives Risk Management Program, comply with certain VaR-based leverage limits, and comply with certain Board oversight and reporting requirements if the Fund’s “derivatives exposure” (as defined in Rule 18f-4) is limited to 10% of its net assets (as calculated in accordance with Rule 18f-4) and the Fund adopts and implements written policies and procedures reasonably designed to manage its derivatives risks (the “Limited Derivatives User Exception”).

Pursuant to Rule 18f-4, if the Fund enters into reverse repurchase agreements or similar financing transactions, the Fund will (i) aggregate the amount of indebtedness associated with all of its reverse repurchase agreements or similar financing transactions with the amount of any other “senior securities” representing indebtedness (e.g., bank borrowings, if applicable) when calculating the Fund’s asset coverage ratio or (ii) treat all such transactions as Derivatives Transactions.

The requirements of Rule 18f-4 may limit the Fund’s ability to engage in Derivatives Transactions as part of its investment strategies. These requirements may also increase the cost of the Fund’s investments and cost of doing business, which could adversely affect the value of the Fund’s investments and/or the performance of the Fund.

Futures Transactions

Futures and options on futures entail certain risks, including but not limited to the following:

●

no assurance that futures contracts or options on futures can be offset at favorable prices;

●

possible reduction of the yield of the Fund due to the use of hedging;

●

possible reduction in value of both the securities hedged and the hedging instrument;

●

possible lack of liquidity due to daily limits or price fluctuations;

●

imperfect correlation between the contracts and the securities being hedged; and

●

losses from investing in futures transactions that are potentially unlimited.

The Fund’s ability to establish and close out positions in futures contracts and options thereon will be subject to the development and maintenance of liquid markets. Although the Fund generally will purchase or sell only those futures contracts and options thereon for which there appears to be a liquid market, there is no assurance that a liquid market on an exchange will exist for any particular futures contract or option thereon at any particular time.

In the event no liquid market exists for a particular futures contract or option thereon in which the Fund maintains a position, it will not be possible to effect a closing transaction in that contract or to do so at a satisfactory price and the Fund would have to either make or take delivery under the futures contract or, in the case of a written option, wait to sell the underlying securities until the option expires or is exercised or, in the case of a purchased option, exercise the option. In the case of a futures contract or an option thereon which the Fund has written and which the Fund is unable to close, the Fund would be required to maintain margin deposits on the futures contract or option thereon and to make variation margin payments until the contract is closed.

Successful use of futures contracts and options thereon and forward contracts by the Fund is subject to the ability of the Investment Adviser to predict correctly movements in the direction of interest and foreign currency rates. If the Investment Adviser’s expectations are not met, the Fund will be in a worse position than if a hedging strategy had not been pursued. For example, if the Fund has hedged against the possibility of an increase in interest rates that would adversely affect the price of securities in its portfolio and the price of such securities increases instead, the Fund will lose part or all of the benefit of the increased value of its securities because it will have offsetting losses in its futures positions. In addition, in such situations, if the Fund has insufficient cash to meet daily variation margin requirements, it may have to sell securities to meet the requirements. These sales may be, but will not necessarily be, at increased prices that reflect the rising market. The Fund may have to sell securities at a time when it is disadvantageous to do so.

Swap Agreements

The Fund may enter into total rate of return, credit default, interest rate or other types of swaps and related derivatives for various purposes, including to gain economic exposure to an asset or group of assets that may be difficult or impractical to acquire or for hedging and risk management. Swap agreements involve the risk that the party with whom the Fund has entered into the swap will default on its obligation to pay the Fund and the risk that the Fund will not be able to meet its obligations to pay the other party to the agreement.

Forward Currency Exchange Contracts

The use of forward currency exchange contracts may involve certain risks, including the failure of the counterparty to perform its obligations under the contract and that the use of forward contracts may not serve as a complete hedge because of an imperfect correlation between movements in the prices of the contracts and the prices of the currencies hedged or used for cover.

Counterparty Risk

The Fund will be subject to credit risk with respect to the counterparties to the derivative contracts purchased by the Fund. If a counterparty becomes bankrupt or otherwise fails to perform its obligations under a derivative contract due to financial difficulties, the Fund may experience significant delays in obtaining any recovery under the derivative contract in bankruptcy or other reorganization proceeding. The Fund may obtain only a limited recovery or may obtain no recovery in such circumstances.

Loans of Portfolio Securities

Consistent with applicable regulatory requirements and the Fund’s investment restrictions, the Fund may lend its portfolio securities to securities broker-dealers or financial institutions, provided that such loans are callable at any time by the Fund (subject to certain notice provisions) and are at all times secured by cash or cash equivalents, which are maintained in a segregated account pursuant to applicable regulations and that are at least equal to the market value, determined daily, of the loaned securities. The advantage of such loans is that the Fund continues to receive the income on the loaned securities while at the same time earning interest on the cash amounts deposited as collateral, which will be invested in short term liquid obligations. The Fund will not lend its portfolio securities if such loans are not permitted by the laws or regulations of any state in which its shares are qualified for sale. The Fund’s loans of portfolio securities will be collateralized in accordance with applicable regulatory requirements, which means that “cash equivalents” accepted as collateral will be limited to securities issued or guaranteed by the U.S. Government or its agencies or instrumentalities or irrevocable letters of credit issued by a bank (other than the Fund’s bank lending agent, if any, or a borrower of the Fund’s portfolio securities or any affiliate of such bank or borrower) which qualifies as a custodian bank for an investment company under the 1940 Act.

For a further description of such loans of portfolio securities, see “Investment Objectives and Policies — Certain Investment Practices — Loans of Portfolio Securities.”

Management Risk

The Fund is subject to management risk because it is an actively managed portfolio. The Investment Adviser applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these will produce the desired results.

Dependence on Key Personnel

The Investment Adviser is dependent upon the expertise of Mr. Mario J. Gabelli in providing advisory services with respect to the Fund’s investments. If the Investment Adviser were to lose the services of Mr. Gabelli, its ability to service the Fund could be adversely affected. There can be no assurance that a suitable replacement

could be found for Mr. Gabelli in the event of his death, resignation, retirement or inability to act on behalf of the Investment Adviser.

Legislation Risk

At any time after the date of this report, legislation may be enacted that could negatively affect the assets of the Fund. Legislation or regulation may change the way in which the Fund itself is regulated. The Investment Adviser cannot predict the effects of any new governmental regulation that may be implemented and there can be no assurance that any new governmental regulation will not adversely affect the Fund’s ability to achieve its investment objective.

Reliance on Service Providers Risk

The Fund must rely upon the performance of service providers to perform certain functions, which may include functions that are integral to the Fund’s operations and financial performance. Failure by any service provider to carry out its obligations to the Fund in accordance with the terms of its appointment, to exercise due care and skill or to perform its obligations to the Fund at all as a result of insolvency, bankruptcy or other causes could have a material adverse effect on the Fund’s performance and returns to shareholders. The termination of the Fund’s relationship with any service provider, or any delay in appointing a replacement for such service provider, could materially disrupt the business of the Fund and could have a material adverse effect on the Fund’s performance and returns to shareholders.

Cyber Security Risk

The Fund and its service providers are susceptible to cyber security risks that include, among other things, theft, unauthorized monitoring, release, misuse, loss, destruction or corruption of confidential and highly restricted data; denial of service attacks; unauthorized access to relevant systems, compromises to networks or devices that the Fund and its service providers use to service the Fund’s operations; or operational disruption or failures in the physical infrastructure or operating systems that support the Fund and its service providers. Cyber attacks against or security breakdowns of the Fund or its service providers may adversely impact the Fund and its stockholders, potentially resulting in, among other things, financial losses; the inability of Fund stockholders to transact business and the Fund to process transactions; inability to calculate the Fund’s NAV; violations of applicable privacy and other laws; regulatory fines, penalties, reputational damage, reimbursement or other compensation costs; and/or additional compliance costs. The Fund may incur additional costs for cyber security risk management and remediation purposes. In addition, cyber security risks may also impact issuers of securities in which the Fund invests, which may cause the Fund’s investment in such issuers to lose value. There can be no assurance that the Fund or its service providers will not suffer losses relating to cyber attacks or other information security breaches in the future.

Misconduct of Employees and of Service Providers Risk

Misconduct or misrepresentations by employees of the Investment Adviser or the Fund’s service providers could cause significant losses to the Fund. Employee misconduct may include binding the Fund to transactions that exceed authorized limits or present unacceptable risks and unauthorized trading activities, concealing unsuccessful trading activities (which, in any case, may result in unknown and unmanaged risks or losses) or making misrepresentations regarding any of the foregoing. Losses could also result from actions by the

Fund’s service providers, including, without limitation, failing to recognize trades and misappropriating assets. In addition, employees and service providers may improperly use or disclose confidential information, which could result in litigation or serious financial harm, including limiting the Fund’s business prospects or future marketing activities. Despite the Investment Adviser’s due diligence efforts, misconduct and intentional misrepresentations may be undetected or not fully comprehended, thereby potentially undermining the Investment Adviser’s due diligence efforts. As a result, no assurances can be given that the due diligence performed by the Investment Adviser will identify or prevent any such misconduct.

Anti-Takeover Provisions of the Fund’s Governing Documents

The Fund’s Governing Documents include provisions that could limit the ability of other entities or persons to acquire control of the Fund or convert the Fund to an open-end fund.

Status as a Regulated Investment Company

The Fund has qualified, and intends to remain qualified, for federal income tax purposes as a regulated investment company under Subchapter M of the Code. Qualification requires, among other things, compliance by the Fund with certain distribution requirements. Statutory limitations on distributions on the common stock if the Fund fails to satisfy the 1940 Act’s asset coverage requirements could jeopardize the Fund’s ability to meet such distribution requirements. The Fund presently intends, however, to purchase or redeem preferred stock to the extent necessary in order to maintain compliance with such asset coverage requirements.

Temporary Investments

During temporary defensive periods and during inopportune periods to be fully invested, the Fund may invest in U.S. government securities, including U.S. Treasury securities, and in money market mutual funds that invest in those securities. Obligations of certain agencies and instrumentalities of the U.S. government, such as the Government National Mortgage Association, are supported by the “full faith and credit” of the U.S. government; others, such as those of the Export-Import Bank of the United States, are supported by the right of the issuer to borrow from the U.S. Treasury; others, such as those of the Federal National Mortgage Association, are supported by the discretionary authority of the U.S. government to purchase the agency’s obligations; and still others, such as those of the Student Loan Marketing Association, are supported only by the credit of the instrumentality. No assurance can be given that the U.S. government would provide financial support to U.S. government-sponsored instrumentalities if it is not obligated to do so by law.

Senior Securities / leverage

As of December 31, 2022, the Fund uses leverage through the issuance of preferred shares.

Effects of Leverage

The following information is furnished in response to requirements of the SEC. It is designed to, among other things, illustrate the effects of leverage through the use of senior securities, as that term is defined under Section 18 of the 1940 Act, on Common Share total return, assuming investment portfolio total returns (consisting of income and changes in the value of investments held in a Fund’s portfolio) of -10%, -5%, 0%, 5% and 10%. The table below reflects the Fund’s continued use of preferred shares, as of December 31, 2022 as a percentage of total managed assets (including assets attributable to such leverage), the estimated annual effective preferred

shares dividend rate and interest expense rate payable by the Fund on such instruments (based on market conditions as of December 31, 2022), and the annual return that the Fund’s portfolio must experience (net of expenses) in order to cover such costs. The information below does not reflect the Fund’s use of certain other forms of economic leverage achieved through the use of other instruments or transactions not considered to be senior securities under the 1940 Act, such as derivative instruments.

Preferred Shares as a Percentage of Total Managed Assets (Including Assets
Attributable to Preferred Shares)	22%
Estimated Annual Effective Preferred Share Dividend Rate	5.42%
Annual Return Fund Portfolio Must Experience (net of expenses) to Cover
Estimated Annual Effective Preferred Share Dividend Rate	1.20%
Common Share Total Return for (10.00)% Assumed Portfolio Total Return
Common Share Total Return for (5.00)% Assumed Portfolio Total Return	(8.22)%
Common Share Total Return for 0.00% Assumed Portfolio Total Return	(1.81)%
Common Share Total Return for 5.00% Assumed Portfolio Total Return	4.60%
Common Share Total Return for 10.00% Assumed Portfolio Total Return	11.01%

Common shares total return is composed of two elements — the distributions paid by a Fund to holders of common shares (the amount of which is largely determined by the net investment income of the Fund after paying dividend payments on any preferred shares issued by the Fund and expenses on any forms of leverage outstanding) and gains or losses on the value of the securities and other instruments the Fund owns. As required by SEC rules, the table assumes that a Fund is more likely to suffer capital losses than to enjoy capital appreciation. For example, to assume a total return of 0%, a Fund must assume that the income it receives on its investments is entirely offset by losses in the value of those investments. This table reflects hypothetical performance of the Fund’s portfolio and not the actual performance of the Fund’s common shares, the value of which is determined by market forces and other factors. Should the Fund elect to add additional leverage to its portfolio, any benefits of such additional leverage cannot be fully achieved until the proceeds resulting from the use of such leverage have been received by the Fund and invested in accordance with the Fund’s investment objectives and policies. As noted above, the Fund’s willingness to use additional leverage, and the extent to which leverage is used at any time, will depend on many factors, including, among other things, the Fund’s assessment of the yield curve environment, interest rate trends, market conditions and other factors.

Capital Stock [Table Text Block]

6. Capital. The Fund’s Articles of Incorporation, as amended, permit the Fund to issue 337,024,900 shares of common stock (par value $0.001) and authorizes the Board to increase its authorized shares from time to time. The Board has authorized the repurchase of its shares on the open market when the shares are trading on the NYSE at a discount of 10% or more (or such other percentage as the Board may determine from time to time) from the NAV of the shares. During the years ended December 31, 2022 and 2021, the Fund did not repurchase any shares of its common stock in the open market.

Transactions in shares of common stock were as follows:

	Year Ended December 31, 2022				Year Ended December 31, 2021
	Shares		Amount		Shares		Amount

Increase in net assets from common shares issued in offering		—	$	—		26,266,993	$	144,468,461
Net increase in net assets from common shares issued upon reinvestment of distributions		4,612,791		26,642,626		3,756,708		24,693,950
Net increase		4,612,791	$	26,642,626		30,023,701	$	169,162,411

On June 22, 2021, the Fund distributed one transferable right for each of the 263,511,620 common shares outstanding held on that date. Ten rights were required to purchase one additional common share at the subscription price of $5.50 per share. On July 21, 2021, the Fund issued 26,266,993 common shares receiving net proceeds of $143,868,461 after the deduction of offering expenses of $600,000. The NAV of the Fund decreased by $0.10 per share on the day the additional shares were issued due to the additional shares being issued below NAV.

The Fund has an effective shelf registration authorizing the offering of $355 million of additional common or preferred stock.

The Fund’s Articles of Incorporation, as amended, authorize the issuance of up to 18,000,000 shares of $0.001 par value Preferred Stock. The Preferred Stock is senior to the common stock and results in the financial leveraging of the common stock. Such leveraging tends to magnify both the risks and opportunities to common stockholders. Dividends on shares of the Preferred Stock are cumulative. The Fund is required by the 1940 Act and by the Fund’s Articles Supplementary to meet certain asset coverage tests with respect to the Preferred Stock. If the Fund fails to meet these requirements and does not correct such failure, the Fund may be required to redeem, in part or in full, the Series C, Series E, Series G, Series H, Series K, and Series M Preferred Stock

at redemption prices of $25,000, $25,000, $25, $25, $25, and $100, respectively, per share plus an amount equal to the accumulated and unpaid dividends whether or not declared on such shares in order to meet these requirements. Additionally, failure to meet the foregoing asset coverage requirements could restrict the Fund’s ability to pay dividends to common stockholders and could lead to sales of portfolio securities at inopportune times. The income received on the Fund’s assets may vary in a manner unrelated to the fixed and variable rates, which could have either a beneficial or detrimental impact on net investment income and gains available to common stockholders.

On December 17, 2021, January 31, 2022, and March 28, 2022, the Fund issued 678,500 shares, 5,000 shares, and 2,000 shares, respectively, of 4.25% Series M Cumulative Preferred Shares, receiving combined net proceeds of $67,745,574, after the deduction of combined offering expenses of $804,426. The Series M Preferred Shares have a liquidation value of $100 per share, and are callable at the Fund’s option at any time on or after March 26, 2027.

On January 31, 2022 (the Redemption Date), the Fund redeemed and retired all Series J Preferred at the redemption price of $25.132465 per Series J Preferred, which was equal to the liquidation preference of $25.00 per share plus $0.132465 per share representing accumulated and unpaid dividends to the Redemption Date.

For Series C and Series E Preferred Stock, the dividend rates, as set by the auction process that is generally held every seven days, are expected to vary with short term interest rates. Since February 2008, the number of shares of Series C and Series E Preferred Stock subject to bid orders by potential holders has been less than the number of shares of Series C and Series E Preferred Stock subject to sell orders. Holders that have submitted sell orders have not been able to sell any or all of the Series C and Series E Preferred Stock for which they have submitted sell orders. Therefore, the weekly auctions have failed, and the dividend rate has been the maximum rate. For Series C and Series E Preferred Stock, the maximum auction rate is 175% of the “AA” Financial Composite Commercial Paper Rate. Existing Series C and Series E stockholders may submit an order to hold, bid, or sell such shares on each auction date, or trade their shares in the secondary market.

The Fund may redeem at any time, in whole or in part, the Series C, Series E, Series G, and Series H Preferred Stock and may redeem the Series K Preferred and Series M Preferred at any time after December 10, 2024 and March 26, 2027, respectively, at their respective liquidation prices plus any accrued and unpaid dividends. In addition, the Board has authorized the repurchase of the Series G, Series H, and Series K Preferred Stock in the open market at a price less than the $25 liquidation value per share. During the year ended December 31, 2021, the Fund did not repurchase any Preferred Stock. During the year ended December 31, 2022, the Fund repurchased 177,227 Series G Preferred, 45,060 Series H Preferred, and 63,289 Series K Preferred at discounts of 5.5%, 10.9%, and 12.9%, respectively, from their liquidation preferences of $25 per share.

The Fund has the authority to purchase its auction rate Series C and Series E Preferred Stock through negotiated private transactions. The Fund is not obligated to purchase any dollar amount or number of auction rate Preferred Stock, and the timing and amount of any auction rate Preferred Stock purchased will depend on market conditions, share price, capital availability, and other factors. The Fund is neither soliciting holders to sell these shares nor recommending that holders offer them to the Fund. Any offers can be accepted or rejected, at the Fund’s discretion.

The holders of Preferred Shares generally are entitled to one vote per share held on each matter submitted to a vote of stockholders of the Fund and will vote together with holders of common stock as a single class. The holders of Preferred Shares voting together as a single class also have the right currently to elect two Directors and, under certain circumstances, are entitled to elect a majority of the Board of Directors. In addition, the affirmative vote of a majority of the votes entitled to be cast by holders of all outstanding shares of the preferred shares, voting as a single class, will be required to approve any plan of reorganization adversely affecting the preferred stock, and the approval of two-thirds of each class, voting separately, of the Fund’s outstanding voting stock must approve the conversion of the Fund from a closed-end to an open-end investment company. The approval of a majority (as defined in the 1940 Act) of the outstanding preferred shares and a majority (as defined in the 1940 Act) of the Fund’s outstanding voting securities are required to approve certain other actions, including changes in the Fund’s investment objectives or fundamental investment policies.

Special Risks to Holders of Fixed Rate Preferred Stock

Market Price Fluctuation. Shares of Fixed Rate Preferred Stock that are listed on a national securities exchange may trade at a premium to or discount from liquidation value for various reasons, including changes in interest rates.

Common Stock Repurchases. Repurchases of common stock by the Fund may reduce the net asset coverage of the preferred stock, which could adversely affect their liquidity or market prices, if such preferred shares are listed on a national securities exchange.

Common Stock Distribution Policy. In the event the Fund does not generate a total return from dividends and interest received and net realized capital gains in an amount at least equal to its distributions for a given year, the Fund may return capital as part of its distribution. This would decrease the asset coverage per share with respect to the Fund’s preferred stock, which could adversely affect its liquidity or market prices, if such preferred

shares are listed on a national securities exchange. See “Risk Factors and Special Considerations —Common Stock Distribution Policy Risk.”

Credit Quality Ratings. The Fund may obtain credit quality ratings for its preferred stock, if desired; however, it is not required to do so and may issue shares of preferred stock without any rating. If rated, the Fund does not impose any minimum rating necessary to issue such shares. In order to obtain and maintain attractive credit quality ratings for preferred stock or borrowings, if desired, the Fund’s portfolio must satisfy over-collateralization tests established by the relevant rating agencies. These tests are more difficult to satisfy to the extent the Fund’s portfolio securities are of lower credit quality, longer maturity or not diversified by issuer and industry within the meaning of such rating agencies’ over-collateralization tests. These guidelines could affect portfolio decisions and may be more stringent than those imposed by the 1940 Act. With respect to ratings (if any) of the preferred stock, a rating by a ratings agency does not eliminate or necessarily mitigate the risks of investing in our preferred stock, and a rating may not fully or accurately reflect all of the securities’ credit risks. A rating does not address the liquidity or any other market risks of the securities being rated. A rating agency could downgrade the rating of our preferred stock, which may make such securities less liquid in the secondary market. If a rating agency downgrades the rating assigned to our preferred stock, we may alter our portfolio or redeem all or a portion of the preferred stock that are then redeemable under certain circumstances.

●

Portfolio Guidelines of Rating Agencies for Preferred Stock and/or Credit Facility. In order to obtain and maintain attractive credit quality ratings for preferred stock, if desired, the Fund must comply with investment quality, diversification and other guidelines established by the relevant rating agencies. These tests tend to require over-collateralization and may be more difficult to satisfy to the extent the Fund’s portfolio securities are of lower credit quality, longer maturity or not diversified by issuer and industry within the meaning of such rating agencies’ collateralization tests. These guidelines could affect portfolio decisions and may be more stringent than those imposed by the 1940 Act. In the event that a rating on the Fund’s preferred stock is lowered or withdrawn by the relevant rating agency, the Fund may also be required to redeem all or part of its outstanding preferred stock, and the common stock of the Fund will lose the potential benefits associated with a leveraged capital structure.

●

Impact on Common Stock. Assuming that leverage will (1) be equal in amount to approximately 22% of the Fund’s total net assets, and (2) charge interest or involve dividend payments at a projected blended annual average leverage dividend or interest rate of 5.42%, then the annual return generated by the Fund’s portfolio (net of estimated expenses) must exceed approximately 1.20% of the Fund’s total net assets in order to cover such interest or dividend payments and other expenses specifically related to leverage. These numbers are merely estimates, used for illustration. Actual dividend rates, interest or payment rates may vary frequently and may be significantly higher or lower than the rate estimated above. The following table is furnished in response to requirements of the SEC. It is designed to illustrate the effect of leverage on common stock total return, assuming investment portfolio total returns (comprised of net investment income of the Fund, realized gains or losses of the Fund and changes in the value of the securities held in the Fund’s portfolio) of -10%, -5%, 0%, 5% and 10%. These assumed investment portfolio returns are hypothetical figures and are not necessarily indicative of the investment portfolio returns experienced or expected to be experienced by the Fund. See “Risks.” The table further reflects leverage representing 22% of the Fund’s net assets, the Fund’s current projected blended annual average leverage dividend or interest rate of 5.42%, a management fee at an annual rate of 1.00%

of the liquidation preference of any outstanding preferred stock and estimated annual incremental expenses attributable to any outstanding preferred stock of 0.01% of the Fund’s net assets attributable to shares of common stock.

Assumed Portfolio Total Return (Net of Expenses)	(10.00)%	(5.00)%	0.00%	5.00%	10.00%
Common Stock Total Return	(14.63)%	(8.22)%	(1.81)%	4.60%	11.01%

Common stock total return is composed of two elements — the common share distributions paid by the Fund (the amount of which is largely determined by the taxable income of the Fund (including realized gains or losses) after paying interest on any debt and/or dividends on any preferred stock) and unrealized gains or losses on the value of the securities the Fund owns. As required by SEC rules, the table assumes that the Fund is more likely to suffer capital losses than to enjoy total return. For example, to assume a total return of 0% the Fund must assume that the income it receives on its investments is entirely offset by expenses and losses in the value of those investments.

Common Stock Distribution Policy Risk

The Fund has adopted a policy, which may be changed at any time by the Board, of paying a minimum annual distribution of 10% of the average NAV of the Fund to common stockholders. In the event the Fund does not generate a total return from dividends and interest received and net realized capital gains in an amount equal to or in excess of its stated distribution in a given year, the Fund may return capital as part of such distribution, which may have the effect of decreasing the asset coverage per share with respect to the Fund’s preferred stock. Any return of capital should not be considered by investors as yield or total return on their investment in the Fund. For the fiscal year ended December 31, 2022, the Fund made distributions of $0.60 per share of common stock, of which $0.31 per share was deemed return of capital. The Fund has made quarterly distributions with respect to its common stock since 1987. A portion of the distributions to common stockholders during 23 of the 35 fiscal years that distributions were paid since the Fund’s inception has constituted a return of capital. The composition of each distribution is estimated based on the earnings of the Fund as of the record date for each distribution. The actual composition of each of the current year’s distributions will be based on the Fund’s investment activity through the end of the calendar year.

Non-Diversified Status

The Fund is classified as a “non-diversified” investment company under the 1940 Act, which means it is not limited by the 1940 Act in the proportion of its assets that may be invested in the securities of a single issuer. As a non-diversified investment company, the Fund may invest in the securities of individual issuers to a greater degree than a diversified investment company. As a result, the Fund may be more vulnerable to events affecting a single issuer and therefore subject to greater volatility than a fund that is more broadly diversified. Accordingly, an investment in the Fund may present greater risk to an investor than an investment in a diversified company. To qualify as a “regulated investment company,” or “RIC,” for purposes of the Code, the Fund has in the past conducted and intends to conduct its operations in a manner that will relieve it of any liability for federal income tax to the extent its earnings are distributed to stockholders. To so qualify as a “regulated investment company,” among other requirements, the Fund will limit its investments so that, at the close of each quarter of the taxable year:

●

not more than 25% of the market value of its total assets will be invested in the securities (other than United States government securities or the securities of other RICs) of a single issuer, any two or more issuers in which the Fund owns 20% or more of the voting securities and which are determined to be engaged in the same, similar or related trades or businesses or in the securities of one or more qualified publicly traded partnerships (as defined in the Code); and

●

at least 50% of the market value of the Fund’s assets will be represented by cash, securities of other RICs, United States government securities and other securities, with such other securities limited in respect of any one issuer to an amount not greater than 5% of the value of its assets and not more than 10% of the outstanding voting securities of such issuer.

Equity Risk

Investing in the Fund involves equity risk, which is the risk that the securities held by the Fund will fall in market value due to adverse market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate and the particular circumstances and performance of particular companies whose securities the Fund holds. An investment in the Fund represents an indirect economic stake in the securities owned by the Fund, which are for the most part traded on securities exchanges or in the OTC markets. The market value of these securities, like other market investments, may move up or down, sometimes rapidly and unpredictably. The NAV of the Fund may at any point in time be worth less than the amount at the time the stockholder invested in the Fund, even after taking into account any reinvestment of distributions.

Special Risks Related to Fund Investments in Preferred Securities

There are special risks associated with the Fund’s investing in preferred securities, including:

●

Deferral. Preferred securities may include provisions that permit the issuer, at its discretion, to defer dividends or distributions for a stated period without any adverse consequences to the issuer. If the Fund owns a preferred security that is deferring its dividends or distributions, the Fund may be required to report income for tax purposes although it has not yet received such income.

●

Non-Cumulative Dividends. Some preferred securities are non-cumulative, meaning that the dividends do not accumulate and need not ever be paid. A portion of the portfolio may include investments in non-cumulative preferred securities, whereby the issuer does not have an obligation to make up any arrearages to its stockholder. Should an issuer of a non-cumulative preferred security held by the Fund determine not to pay dividends or distributions on such security, the Fund’s return from that security may be adversely affected. There is no assurance that dividends or distributions on non-cumulative preferred securities in which the Fund invests will be declared or otherwise made payable.

●

Subordination. Preferred securities are subordinated to bonds and other debt instruments in an issuer’s capital structure in terms of priority to corporate income and liquidation payments, and therefore will be subject to greater credit risk than more senior debt security instruments.

●

Liquidity. Preferred securities may be substantially less liquid than many other securities, such as common stocks or U.S. government securities.

●

Limited Voting Rights. Generally, preferred security holders (such as the Fund) have no voting rights with respect to the issuing company unless preferred dividends have been in arrears for a specified number of periods, at which time the preferred security holders may be entitled to elect a number of directors to the issuer’s board. Generally, once all the arrearages have been paid, the preferred security holders no longer have voting rights.

●

Special Redemption Rights. In certain varying circumstances, an issuer of preferred securities may redeem the securities prior to a specified date. For instance, for certain types of preferred securities, a redemption may be triggered by a change in federal income tax or securities laws. A redemption by the issuer may negatively impact the return of the security held by the Fund.

●

Phantom Income. Some preferred securities are classified as debt for U.S. federal income tax purposes. If a debt instrument is issued with original issue discount, the Fund could recognize taxable income in advance of the receipt of cash on the investment. This “phantom income” may require the Fund to liquidate other investments (including when it is not advantageous to do so) to meet its distribution requirements or otherwise qualify for treatment as a RIC.

Market Disruption and Geopolitical Risk

The consequences of the conflict between Russia and Ukraine, including international sanctions, further impact on inflation and increased disruption to supply chains may impact our portfolio companies, result in an economic downturn or recession either globally or locally in the U.S. or other economies, reduce business activity, spawn additional conflicts (whether in the form of traditional military action, reignited “cold” wars or in the form of virtual warfare such as cyberattacks) with similar and perhaps wider ranging impacts and consequences and have an adverse impact on the Fund’s returns and NAV.

The occurrence of events similar to those in recent years, such as localized wars, instability, new and ongoing pandemics (such as COVID-19), epidemics or outbreaks of infectious diseases in certain parts of the world, natural/environmental disasters, terrorist attacks in the United States and around the world, social and political discord, debt crises sovereign debt downgrades, increasingly strained relations between the United States and a number of foreign countries, new and continued political unrest in various countries, the exit or potential exit of one or more countries from the European Union (“EU”) or the Economic and Monetary Union, continued changes in the balance of political power among and within the branches of the U.S. government, government shutdowns, among others, may result in market volatility, may have long term effects on the U.S. and worldwide financial markets, and may cause further economic uncertainties in the United States and worldwide. The current contentious domestic political environment, as well as political and diplomatic events within the United States and abroad, such as the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan, may in the future result in government shutdowns, which could have a material adverse effect on the Fund’s investments and operations. In addition, the Fund’s ability to raise additional capital in the future through the sale of securities could be materially affected by a government shutdown. Additional and/ or prolonged U.S. government shutdowns may affect investor and consumer confidence and may adversely impact financial markets and the broader economy, perhaps suddenly and to a significant degree. In particular, the escalation of the conflict between Russia and Ukraine, including international sanctions, further impact on inflation and increased disruption to supply chains may impact our portfolio companies. Such unfavorable

economic conditions also may also be expected to increase our funding costs, limit our access to the capital markets or result in a decision by lenders not to extend credit to us. The current political climate has intensified concerns about a potential trade war between China and the United States, as each country has recently imposed tariffs on the other country’s products. These actions may trigger a significant reduction in international trade, the oversupply of certain manufactured goods, substantial price reductions of goods and possible failure of individual companies and/or large segments of China’s export industry, which could have a negative impact on our performance. U.S. companies that source material and goods from China and those that make large amounts of sales in China would be particularly vulnerable to an escalation of trade tensions. Uncertainty regarding the outcome of the trade tensions and the potential for a trade war could cause the U.S. dollar to decline against safe haven currencies, such as the Japanese yen and the euro. Events such as these and their consequences are difficult to predict and it is unclear whether further tariffs may be imposed or other escalating actions may be taken in the future. Any of these effects could have a material adverse effect on our business, financial condition and results of operations.

On January 31, 2020, the United Kingdom (“UK”) officially withdrew from the EU (commonly known as “Brexit”). The UK and EU reached a preliminary trade agreement, which became effective on January 1, 2021, regarding the terms of their future trading relationship relating principally to the trading of goods; however, negotiations are ongoing for matters not covered by the agreement, such as the trade of financial services. Due to uncertainty of the current political environment, it is not possible to foresee the form or nature of the future trading relationship between the UK and the EU. The longer term economic, legal, political and social framework to be put in place between the UK and the EU remains unclear and the ongoing political and economic uncertainty and periods of exacerbated volatility in both the UK and in wider European markets may continue for some time. In particular, Brexit may lead to a call for similar referendums in other European jurisdictions which may cause increased economic volatility in the European and global markets and may destabilize some or all of the other EU member countries. This uncertainty may have an adverse effect on the economy generally and on the ability of the Fund and its investments to execute their respective strategies, to receive attractive returns and/or to exit certain investments at an advantageous time or price. In particular, currency volatility may mean that the returns of the Fund and its investments are adversely affected by market movements and may make it more difficult, or more expensive, if the Fund elects to execute currency hedges. Potential decline in the value of the British Pound and/or the Euro against other currencies, along with the potential downgrading of the UK’s sovereign credit rating, may also have an impact on the performance of portfolio companies or investments located in the UK or Europe. In light of the above, no definitive assessment can currently be made regarding the impact that Brexit will have on the Fund, its investments or its organization more generally.

While the extreme volatility and disruption that U.S. and global markets experienced for an extended period of time beginning in 2007 and 2008 had, until the recent coronavirus (COVID-19) outbreak, generally subsided, uncertainty and periods of volatility still remain, and risks to a robust resumption of growth persist. Federal Reserve policy, including with respect to certain interest rates, may adversely affect the value, volatility and liquidity of dividend and interest paying securities. Market volatility, dramatic changes to interest rates and/or a return to unfavorable economic conditions may lower the Fund’s performance or impair the Fund’s ability to achieve its investment objective.

Cybersecurity incidents affecting particular companies or industries may adversely affect the economies of particular countries, regions or parts of the work in which the Fund invests.

The occurrence of any of these above events could have a significant adverse impact on the value and risk profile of the Fund’s portfolio. The Fund does not know how long the securities markets may be affected by similar events and cannot predict the effects of similar events in the future on the U.S. economy and securities markets. There can be no assurance that similar events and other market disruptions will not have other material and adverse implications.

Regulation and Government Intervention Risk

Federal, state, and other governments, their regulatory agencies or self-regulatory organizations may take actions that affect the regulation of the issuers in which the Fund invests in ways that are unforeseeable. Legislation or regulation may also change the way in which the Fund is regulated. Such legislation or regulation could limit or preclude the Fund’s ability to achieve its investment objective.

In light of popular, political and judicial focus on finance related consumer protection. Financial institution practices are also subject to greater scrutiny and criticism generally. In the case of transactions between financial institutions and the general public, there may be a greater tendency toward strict interpretation of terms and legal rights in favor of the consuming public, particularly where there is a real or perceived disparity in risk allocation and/or where consumers are perceived as not having had an opportunity to exercise informed consent to the transaction. In the event of conflicting interests between retail investors holding common shares

of a closed-end investment company such as the Fund and a large financial institution, a court may similarly seek to strictly interpret terms and legal rights in favor of retail investors.

The Fund may be affected by governmental action in ways that are not foreseeable, and there is a possibility that such actions could have a significant adverse effect on the Fund and its ability to achieve its investment objective.

Deflation Risk

Deflation risk is the risk that prices throughout the economy decline over time, which may have an adverse effect on the market valuation of companies, their assets and their revenues. In addition, deflation may have an adverse effect on the creditworthiness of issuers and may make issuer default more likely, which may result in a decline in the value of the Fund’s portfolio.

Foreign Securities

The Fund may invest up to 35% of its total assets in securities of foreign issuers, including emerging market issuers, determined at the time of purchase. Investments in the securities of foreign issuers involve certain considerations and risks not ordinarily associated with investments in securities of domestic issuers and such securities may be more volatile than those of issuers in the United States. Foreign companies are not generally subject to uniform accounting, auditing and financial standards, and requirements comparable to those applicable to United States companies. Foreign securities exchanges, brokers and listed companies may be subject to less government supervision and regulation than exists in the United States. Dividend and interest income may be subject to withholding and other foreign taxes, which may adversely affect the net return on such investments. There may be difficulty in obtaining or enforcing a court judgment abroad. In addition, it may be difficult to effect repatriation of capital invested in certain countries. Also, with respect to certain countries, there are risks of expropriation, confiscatory taxation, political or social instability or diplomatic developments that could affect assets of the Fund held in foreign countries. Dividend income that the Fund receives from foreign securities may not be eligible for the special tax treatment applicable to qualified dividend income. Moreover, certain equity investments in foreign issuers classified as passive foreign investment companies may be subject to additional taxation risk.

There may be less publicly available information about a foreign company than a United States company. Foreign securities markets may have substantially less volume than United States securities markets and some foreign company securities are less liquid than securities of otherwise comparable United States companies. A portfolio of foreign securities may also be adversely affected by fluctuations in the rates of exchange between the currencies of different nations and by exchange control regulations. Foreign markets also have different clearance and settlement procedures that could cause the Fund to encounter difficulties in purchasing and selling securities on such markets and may result in the Fund missing attractive investment opportunities or experiencing loss. In addition, a portfolio that includes foreign securities can expect to have a higher expense ratio because of the increased transaction costs on non-United States securities markets and the increased costs of maintaining the custody of foreign securities.

The Fund also may purchase sponsored American Depositary Receipts (“ADRs”) or United States dollar denominated securities of foreign issuers, including emerging market issuers. ADRs are receipts issued by United States banks or trust companies in respect of securities of foreign issuers held on deposit for use in the United States securities markets. While ADRs may not necessarily be denominated in the same currency as the securities into which they may be converted, many of the risks associated with foreign securities may also apply to ADRs. In addition, the underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute stockholder communications to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited securities.

Smaller Companies

The Fund may invest in smaller companies that may benefit from the development of new products and services. These smaller companies may present greater opportunities for capital appreciation, and may also involve greater investment risk than larger, more established companies. For example, smaller companies may have more limited product lines, market or financial resources and their securities may trade less frequently and in lower volume than the securities of larger, more established companies. As a result, the prices of the securities of such smaller companies may fluctuate to a greater degree than the prices of securities of other issuers.

Fixed Income Securities

FixFixed income securities in which the Fund may invest are generally subject to the following risks:

●

Interest Rate Risk. The market value of bonds and other fixed-income or dividend paying securities changes in response to interest rate changes and other factors. Interest rate risk is the risk that prices of bonds and other income or dividend paying securities will increase as interest rates fall and decrease as interest rates rise. The Fund may be subject to a greater risk of rising interest rates due to the recent period of historically low interest rates. The Federal Reserve has recently begun to raise the federal funds rate as part of its efforts to address rising inflation. There is a risk that interest rates will continue to rise, which will likely drive down prices of bonds and other fixed-income securities. The magnitude of these price reductions in the market price of bonds and other fixed-income securities is generally greater for those securities with longer maturities. Fluctuations in the market price of the Fund’s investments will not affect interest income derived from instruments already owned by the Fund, but will be reflected in the Fund’s NAV. The Fund may lose money if short-term or long-term interest rates rise sharply in a manner not anticipated by the Investment Adviser.

●

Issuer Risk. Issuer risk is the risk that the value of an income or dividend paying security may decline for a number of reasons which directly relate to the issuer, such as management performance, financial leverage, reduced demand for the issuer’s goods and services, historical and prospective earnings of the issuer, and the value of the assets of the issuer.

●

Credit Risk. Credit risk is the risk that one or more income or dividend paying securities in the Fund’s portfolio will decline in price or fail to pay interest/distributions or principal when due because the issuer of the security experiences a decline in its financial status. Credit risk is increased when a portfolio security is downgraded or the perceived creditworthiness of the issuer deteriorates.

●

Prepayment Risk. Prepayment risk is the risk that during periods of declining interest rates, borrowers may exercise their option to prepay principal earlier than scheduled. For income or dividend paying securities, such payments often occur during periods of declining interest rates, forcing the Fund to re-

invest in lower yielding securities, resulting in a possible decline in the Fund’s income and distributions to shareholders.

●

Reinvestment Risk. Reinvestment risk is the risk that income from the Fund’s portfolio will decline if the Fund invests the proceeds from matured, traded or called fixed income securities at market interest rates that are below the Fund portfolio’s current earnings rate.

●

Duration and Maturity Risk. The Fund may incur costs in seeking to adjust the portfolio average duration or maturity. In comparison to maturity (which is the date on which the issuer of a debt instrument is obligated to repay the principal amount), duration is a measure of the price volatility of a debt instrument as a result in changes in market rates of interest, based on the weighted average timing of the instrument’s expected principal and interest payments. Specifically, duration measures the anticipated percentage change in NAV that is expected for every percentage point change in interest rates. The two have an inverse relationship. For example, a duration of five years means that a 1% decrease in interest rates will increase the NAV of the portfolio by approximately 5%; if interest rates increase by 1%, the NAV will decrease by 5%. However, in a managed portfolio of fixed income securities having differing interest or dividend rates or payment schedules, maturities, redemption provisions, call or prepayment provisions and credit qualities, actual price changes in response to changes in interest rates may differ significantly from a duration-based estimate at any given time. Actual price movements experienced by a portfolio of fixed income securities will be affected by how interest rates move (i.e., changes in the relationship of long term interest rates to short term interest rates), the magnitude of any move in interest rates, actual and anticipated prepayments of principal through call or redemption features, the extension of maturities through restructuring, the sale of securities for portfolio management purposes, the reinvestment of proceeds from prepayments on and from sales of securities, and credit quality-related considerations whether associated with financing costs to lower credit quality borrowers or otherwise, as well as other factors. Accordingly, while duration maybe a useful tool to estimate potential price movements in relation to changes in interest rates, investors are cautioned that duration alone will not predict actual changes in the net asset or market value of the Fund’s shares and that actual price movements in the Fund’s portfolio may differ significantly from duration-based estimates. Duration differs from maturity in that it takes into account a security’s yield, coupon payments and its principal payments in addition to the amount of time until the security matures. As the value of a security changes over time, so will its duration. There can be no assurance that the Investment Adviser’s assessment of current and projected market conditions will be correct or that any strategy to adjust duration or maturity will be successful at any given time.

●

Liquidity Risk. Certain fixed income securities in which the Fund invests may be or become illiquid.

Risk [Text Block]

Non-Investment Grade Securities

The Fund may invest up to 10% of its total assets in fixed income securities rated below investment grade by recognized statistical rating agencies or unrated securities of comparable quality. These securities, which may be preferred stock or debt, are predominantly speculative and involve major risk exposure to adverse conditions. Debt securities that are not rated or that are rated lower than “BBB” by S&P or lower than “Baa” by Moody’s are

referred to in the financial press as “junk bonds.” Such securities are subject to greater risks than investment grade securities, which reflect their speculative character, including the following:

●

greater volatility;

●

greater credit risk;

●

potentially greater sensitivity to general economic or industry conditions;

●

potential lack of attractive resale opportunities (illiquidity); and

●

additional expenses to seek recovery from issuers who default.

Fixed income securities purchased by the Fund may be rated as low as C by Moody’s or D by S&P or may be unrated securities considered to be of equivalent quality. Securities that are rated C by Moody’s are the lowest rated class and can be regarded as having extremely poor prospects of ever obtaining investment-grade standing. Debt rated D by S&P is in default or is expected to default upon maturity of payment date.

The market value of lower rated securities may be more volatile than the market value of higher rated securities and generally tends to reflect the market’s perception of the creditworthiness of the issuer and short term market developments to a greater extent than more highly rated securities, which primarily reflect fluctuations in general levels of interest rates. Generally, such non-investment grade securities and unrated securities of comparable quality offer a higher current yield than is offered by higher rated securities, but also (i) will likely have some quality and protective characteristics that, in the judgment of the rating organizations, are outweighed by large uncertainties or major risk exposures to adverse conditions and (ii) are predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal in accordance with the terms of the obligation. The market values of certain of these securities also tend to be more sensitive to individual corporate developments and changes in economic conditions than higher quality securities. In addition, such securities generally present a higher degree of credit risk. The risk of loss due to default by these issuers is significantly greater because such non-investment grade securities and unrated securities of comparable quality generally are unsecured and frequently are subordinated to the prior payment of senior indebtedness. In light of these risks, the Investment Adviser, in evaluating the creditworthiness of an issue, whether rated or unrated, will take various factors into consideration, which may include, as applicable, the issuer’s operating history, financial resources and its sensitivity to economic conditions and trends, the market support for the facility financed by the issue, the perceived ability and integrity of the issuer’s management, and regulatory matters.

Non-investment grade securities also present risks based on payment expectations. If an issuer calls the obligation for redemption (often a feature of fixed income securities), the Fund may have to replace the security with a lower yielding security, resulting in a decreased return for investors. Also, as the principal value of nonconvertible bonds and preferred stocks moves inversely with movements in interest rates, in the event of rising interest rates the value of the securities held by the Fund may decline proportionately more than a portfolio consisting of higher rated securities. Investments in zero coupon bonds may be more speculative and subject to greater fluctuations in value due to changes in interest rates than bonds that pay regular income streams. See “—Fixed Income Securities—Interest Rate Risk” above.

Ratings are relative and subjective, and are not absolute standards of quality. Securities ratings are based largely on the issuer’s historical financial condition and the rating agencies’ analysis at the time of rating.

Consequently, the rating assigned to any particular security is not necessarily a reflection of the issuer’s current financial condition.

As part of its investment in lower grade securities, the Fund may invest in securities of issuers in default. The Fund will make an investment in securities of issuers in default only when the Investment Adviser believes that such issuers will honor their obligations or emerge from bankruptcy protection under a plan pursuant to which the securities received by the Fund in exchange for its defaulted securities will have a value in excess of the Fund’s investment. By investing in securities of issuers in default, the Fund bears the risk that these issuers will not continue to honor their obligations or emerge from bankruptcy protection or that the value of the securities will not otherwise appreciate.

Futures Transactions

Futures and options on futures entail certain risks, including but not limited to the following:

●

no assurance that futures contracts or options on futures can be offset at favorable prices;

●

possible reduction of the yield of the Fund due to the use of hedging;

●

possible reduction in value of both the securities hedged and the hedging instrument;

●

possible lack of liquidity due to daily limits or price fluctuations;

●

imperfect correlation between the contracts and the securities being hedged; and

●

losses from investing in futures transactions that are potentially unlimited.

The Fund’s ability to establish and close out positions in futures contracts and options thereon will be subject to the development and maintenance of liquid markets. Although the Fund generally will purchase or sell only those futures contracts and options thereon for which there appears to be a liquid market, there is no assurance that a liquid market on an exchange will exist for any particular futures contract or option thereon at any particular time.

In the event no liquid market exists for a particular futures contract or option thereon in which the Fund maintains a position, it will not be possible to effect a closing transaction in that contract or to do so at a satisfactory price and the Fund would have to either make or take delivery under the futures contract or, in the case of a written option, wait to sell the underlying securities until the option expires or is exercised or, in the case of a purchased option, exercise the option. In the case of a futures contract or an option thereon which the Fund has written and which the Fund is unable to close, the Fund would be required to maintain margin deposits on the futures contract or option thereon and to make variation margin payments until the contract is closed.

Successful use of futures contracts and options thereon and forward contracts by the Fund is subject to the ability of the Investment Adviser to predict correctly movements in the direction of interest and foreign currency rates. If the Investment Adviser’s expectations are not met, the Fund will be in a worse position than if a hedging strategy had not been pursued. For example, if the Fund has hedged against the possibility of an increase in interest rates that would adversely affect the price of securities in its portfolio and the price of such securities increases instead, the Fund will lose part or all of the benefit of the increased value of its securities because it will have offsetting losses in its futures positions. In addition, in such situations, if the Fund has insufficient cash to meet daily variation margin requirements, it may have to sell securities to meet the requirements. These sales may be, but will not necessarily be, at increased prices that reflect the rising market. The Fund may have to sell securities at a time when it is disadvantageous to do so.

Forward Currency Exchange Contracts

The use of forward currency exchange contracts may involve certain risks, including the failure of the counterparty to perform its obligations under the contract and that the use of forward contracts may not serve as a complete hedge because of an imperfect correlation between movements in the prices of the contracts and the prices of the currencies hedged or used for cover.

Loans of Portfolio Securities

Consistent with applicable regulatory requirements and the Fund’s investment restrictions, the Fund may lend its portfolio securities to securities broker-dealers or financial institutions, provided that such loans are callable at any time by the Fund (subject to certain notice provisions) and are at all times secured by cash or cash equivalents, which are maintained in a segregated account pursuant to applicable regulations and that are at least equal to the market value, determined daily, of the loaned securities. The advantage of such loans is that the Fund continues to receive the income on the loaned securities while at the same time earning interest on the cash amounts deposited as collateral, which will be invested in short term liquid obligations. The Fund will not lend its portfolio securities if such loans are not permitted by the laws or regulations of any state in which its shares are qualified for sale. The Fund’s loans of portfolio securities will be collateralized in accordance with applicable regulatory requirements, which means that “cash equivalents” accepted as collateral will be limited to securities issued or guaranteed by the U.S. Government or its agencies or instrumentalities or irrevocable letters of credit issued by a bank (other than the Fund’s bank lending agent, if any, or a borrower of the Fund’s portfolio securities or any affiliate of such bank or borrower) which qualifies as a custodian bank for an investment company under the 1940 Act.

Dependence on Key Personnel

The Investment Adviser is dependent upon the expertise of Mr. Mario J. Gabelli in providing advisory services with respect to the Fund’s investments. If the Investment Adviser were to lose the services of Mr. Gabelli, its ability to service the Fund could be adversely affected. There can be no assurance that a suitable replacement

could be found for Mr. Gabelli in the event of his death, resignation, retirement or inability to act on behalf of the Investment Adviser.

Reliance on Service Providers Risk

The Fund must rely upon the performance of service providers to perform certain functions, which may include functions that are integral to the Fund’s operations and financial performance. Failure by any service provider to carry out its obligations to the Fund in accordance with the terms of its appointment, to exercise due care and skill or to perform its obligations to the Fund at all as a result of insolvency, bankruptcy or other causes could have a material adverse effect on the Fund’s performance and returns to shareholders. The termination of the Fund’s relationship with any service provider, or any delay in appointing a replacement for such service provider, could materially disrupt the business of the Fund and could have a material adverse effect on the Fund’s performance and returns to shareholders.

Misconduct of Employees and of Service Providers Risk

Misconduct or misrepresentations by employees of the Investment Adviser or the Fund’s service providers could cause significant losses to the Fund. Employee misconduct may include binding the Fund to transactions that exceed authorized limits or present unacceptable risks and unauthorized trading activities, concealing unsuccessful trading activities (which, in any case, may result in unknown and unmanaged risks or losses) or making misrepresentations regarding any of the foregoing. Losses could also result from actions by the

Fund’s service providers, including, without limitation, failing to recognize trades and misappropriating assets. In addition, employees and service providers may improperly use or disclose confidential information, which could result in litigation or serious financial harm, including limiting the Fund’s business prospects or future marketing activities. Despite the Investment Adviser’s due diligence efforts, misconduct and intentional misrepresentations may be undetected or not fully comprehended, thereby potentially undermining the Investment Adviser’s due diligence efforts. As a result, no assurances can be given that the due diligence performed by the Investment Adviser will identify or prevent any such misconduct.

Status as a Regulated Investment Company

The Fund has qualified, and intends to remain qualified, for federal income tax purposes as a regulated investment company under Subchapter M of the Code. Qualification requires, among other things, compliance by the Fund with certain distribution requirements. Statutory limitations on distributions on the common stock if the Fund fails to satisfy the 1940 Act’s asset coverage requirements could jeopardize the Fund’s ability to meet such distribution requirements. The Fund presently intends, however, to purchase or redeem preferred stock to the extent necessary in order to maintain compliance with such asset coverage requirements.

Security Voting Rights [Text Block]

The holders of Preferred Shares generally are entitled to one vote per share held on each matter submitted to a vote of stockholders of the Fund and will vote together with holders of common stock as a single class. The holders of Preferred Shares voting together as a single class also have the right currently to elect two Directors and, under certain circumstances, are entitled to elect a majority of the Board of Directors. In addition, the affirmative vote of a majority of the votes entitled to be cast by holders of all outstanding shares of the preferred shares, voting as a single class, will be required to approve any plan of reorganization adversely affecting the preferred stock, and the approval of two-thirds of each class, voting separately, of the Fund’s outstanding voting stock must approve the conversion of the Fund from a closed-end to an open-end investment company. The approval of a majority (as defined in the 1940 Act) of the outstanding preferred shares and a majority (as defined in the 1940 Act) of the Fund’s outstanding voting securities are required to approve certain other actions, including changes in the Fund’s investment objectives or fundamental investment policies.
