Investment Objectives and Practices [Text Block] |  |  |  |  |  |  |  |  |  | INVESTMENT OBJECTIVES AND POLICIES Investment Objectives and Policies The Fund’s investment objective is to seek a consistent level of after-tax total return over the long-term with an emphasis currently on qualifying dividends. The Fund will attempt to achieve its investment objective by investing, under normal market conditions, at least 80% of its assets in (i) equity securities (including common stock, preferred stock, convertible stock and options on these securities) of domestic and foreign companies involved to a substantial extent (i.e., at least 50% of the assets, gross income or net profits of a company is committed to or derived from) in providing (a) products, services or equipment for the generation or distribution of electricity, gas or water, (b) infrastructure operations such as airports, toll roads and municipal services and (c) telecommunications services such as telephone, telegraph, satellite, cable, microwave, radiotelephone, mobile communication and cellular, paging, electronic mail, videotext, voice communications, data communications and internet (collectively, the “Utilities Industry”) and (ii) securities (including preferred and debt securities, as well as government obligations) of issuers that are expected to periodically pay dividends or interest. The Fund’s 80% policy is not fundamental and shareholders will be notified if it is changed. In addition, under normal market conditions, at least 25% of the Fund’s assets will consist of securities (including preferred and debt securities) of domestic and foreign companies involved to a substantial extent in the Utilities Industry. The remaining Fund assets will generally be invested in other securities that the Investment Adviser views as not being correlated with the Fund’s Utilities Industry investments. Such investments may include convertible securities, securities of issuers subject to reorganization or other risk arbitrage investments, certain derivative instruments including equity contract for difference swap transactions, other debt securities (including obligations of the U.S. Government), and money market instruments. The Fund may invest without limitation in securities of foreign issuers and will generally be invested in securities of issuers located in at least three countries, including the United States. It is anticipated that, under normal market conditions, at least 40% of the Fund’s assets will be invested in foreign securities. Foreign securities are securities of issuers based outside the United States. The Fund considers an issuer to be based outside of the United States if (1) it is organized under the laws of, or has a principal office located in, another country; (2) the principal trading market for its securities is in another country; or (3) it (directly or through its consolidated subsidiaries) derived in its most current fiscal year at least 50% of its total assets, capitalization, gross revenue or profit from goods produced, services performed or sales made in another country. The Fund may purchase sponsored ADRs or U.S. dollar denominated securities of foreign issuers, which will be considered foreign securities for purposes of the Fund’s investment policies. Typically, the Fund will not hold any foreign securities of emerging market issuers and, if it does, such securities are not expected to comprise more than 10% of the Fund’s managed assets. The Fund expects to invest in securities across all market capitalization ranges. The Fund may invest up to 10% of its total assets in securities rated below investment grade by recognized statistical rating agencies or unrated securities of comparable quality, including securities of issuers in default, which are likely to have the lowest rating. Securities rated below investment grade, which may be preferred shares or debt, are predominantly speculative and involve major risk exposure to adverse conditions. Securities that are rated lower than “BBB” by S&P, or lower than “Baa” by Moody’s or unrated securities considered by the Investment Adviser to be of comparable quality, are commonly referred to as “junk bonds” or “high yield” securities. No assurance can be given that the Fund’s investment objective will be achieved. Investment Methodology of the Fund In selecting securities for the Fund, the Investment Adviser normally considers the following factors, among others:
| ● | the industry of the issuer of a security;
| ● | the potential of the Fund to earn gains from writing covered call options on such securities;
| ● | the interest or dividend income generated by the securities;
| ● | the potential for capital appreciation of the securities;
| ● | the prices of the securities relative to comparable securities;
| ● | whether the securities are entitled to the benefits of call protection or other protective covenants;
| ● | the existence of any anti-dilution protections or guarantees of the security; and
| ● | the number and size of investments of the portfolio as to issuers.
The Investment Adviser’s investment philosophy with respect to debt and equity securities is to identify assets that are selling in the public market at a discount to their private market value. The Investment Adviser defines private market value as the value informed purchasers are willing to pay to acquire assets with similar characteristics. The Investment Adviser also normally evaluates an issuer’s free cash flow and long-term earnings trends. Finally, the Investment Adviser looks for a catalyst, something indigenous to the company, its industry or country that will surface additional value. Certain Investment Practices Utilities Industry Concentration. Under normal market conditions the Fund will invest at least 25% of its assets in the securities (including preferred and debt securities) of domestic and foreign companies involved to a substantial extent in the Utilities Industry. Tax-Advantaged Qualified Dividends. The Fund’s investments will emphasize securities that will pay tax-advantaged qualified dividends. For the Fund to receive tax-advantaged qualified dividends, the Fund must, in addition to other requirements, hold the otherwise qualified stock for more than 60 days during the 121-day period beginning 60 days before the ex-dividend date (or, in the case of preferred stock, more than 90 days during the 181-day period beginning 90 days before the ex-dividend date). The “ex-dividend date” is the date which is established by a stock exchange (usually two business days before the record date) whereby the owner of a security at the commencement of such date is entitled to receive the next issued dividend payment for such security, even if the security is sold by such owner on the ex-dividend date or thereafter. In addition, for dividends to be tax-advantaged qualified dividends, the Fund cannot have an option to sell or be under a contractual obligation to sell (pursuant to a short sale or otherwise) substantially identical stock or securities. Accordingly, the Fund’s writing of call options may, depending on the terms of the option, adversely impact the Fund’s ability to pay tax-advantaged qualified dividends. For an individual shareholder to be taxed at the rates applicable to tax-advantaged qualified dividends on dividends received from the Fund that are attributable to tax-advantaged qualified dividends received by the Fund, the shareholder must hold its common shares for more than 61 days during the 121-day period beginning 60 days before the ex-dividend date for the Fund’s common shares (or, in the case of preferred stock, more than 91 days during the 181-day period beginning 90 days before the ex-dividend date for the Fund’s preferred shares). Consequently, short-term investors in the Fund may not realize the benefits of tax-advantaged qualified dividends. There can be no assurance as to the portion of the Fund’s dividends that will be tax-advantaged. Foreign Securities. Subject to the Fund’s other policies including investing at least 25% of its assets in the Utilities Industry, the Fund may invest without limit in the securities of foreign issuers, which are generally denominated in foreign currencies. The Fund expects to generally be invested in securities of issuers located in at least three countries, including the United States and possibly including developing countries. It is anticipated that, under normal market conditions, at least 40% of the Fund’s assets will be invested in foreign securities. Typically, the Fund will not hold any foreign securities of emerging market issuers and, if it does, such securities are not expected to comprise more than 10% of the Fund’s managed assets. The Investment Adviser believes that investing in foreign securities offers both enhanced investment opportunities and additional risks beyond those present in U.S. securities. Investing in foreign securities may provide increased diversification by adding securities from various foreign countries (i) that offer different investment opportunities, (ii) that generally are affected by different economic trends and (iii) whose stock markets may not be correlated with U.S. markets. At the same time, these opportunities and trends involve risks that may not be encountered in U.S. investments. The following considerations comprise both risks and opportunities not typically associated with investing in U.S. securities: fluctuations in exchange rates of foreign currencies; possible imposition of exchange control regulations or currency restrictions that would prevent cash from being brought back to the United States; less public information with respect to issuers of securities; less government supervision of stock exchanges, securities brokers and issuers of securities; the difficulty in obtaining or enforcing a court judgment abroad; lack of uniform accounting, auditing and financial reporting standards; lack of uniform settlement periods and trading practices; less liquidity and frequently greater price volatility in foreign markets than in the United States; possible imposition of foreign taxes; the possibility of expropriation or confiscatory taxation, seizure or nationalization of foreign bank deposits or other assets; the adoption of foreign government restrictions and other adverse political, social or diplomatic developments that could affect investment; sometimes less advantageous legal, operational and financial protections applicable to foreign sub-custodial arrangements; and the historically lower level of responsiveness of foreign management to shareholder concerns (such as dividends and return on investment). The Fund may also purchase sponsored American Depository Receipts (“ADRs”) or U.S. dollar denominated securities of foreign issuers, which will be considered foreign securities for purposes of the Fund’s investment policies. ADRs are receipts issued by U.S. banks or trust companies in respect of securities of foreign issuers held on deposit for use in the U.S. securities markets. See “Risk Factors and Special Considerations—Foreign Securities.” Income Securities. Although it is the Fund’s policy to invest in securities of companies in the Utilities Industry to the extent attractive opportunities are available, the Fund may also invest in income securities other than Utilities Industry securities that are expected to periodically accrue or generate income for their holders. Such income securities include (i) fixed income securities such as bonds, debentures, notes, preferred stock, short-term discounted Treasury Bills or certain securities of the U.S. government sponsored instrumentalities, as well as money market mutual funds that invest in those securities, which, in the absence of an applicable exemptive order or rule, will not be affiliated with the Investment Adviser, and (ii) common and preferred stocks of issuers that have historically paid periodic dividends. Fixed income securities obligate the issuer to pay to the holder of the security a specified return, which may be either fixed or reset periodically in accordance with the terms of the security. Fixed income securities generally are senior to an issuer’s common stock and their holders generally are entitled to receive amounts due before any distributions are made to common stockholders. Common stocks, on the other hand, generally do not obligate an issuer to make periodic distributions to holders. The market value of fixed income securities, especially those that provide a fixed rate of return, may be expected to rise and fall inversely with interest rates and in general is affected by the credit rating of the issuer, the issuer’s performance and perceptions of the issuer in the market place. The market value of callable or redeemable fixed income securities may also be affected by the issuer’s call and redemption rights. In addition, it is possible that the issuer of fixed income securities may not be able to meet its interest or principal obligations to holders. Further, holders of non-convertible fixed income securities do not participate in any capital appreciation of the issuer. The Fund may also invest in obligations of government sponsored instrumentalities. Unlike non-U.S. government 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 U.S., 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. Although the Fund may invest in all types of obligations of agencies and instrumentalities of the U.S. government, the Fund currently intends to invest only in obligations that are supported by the “full faith and credit” of the U.S. government. The Fund also may invest in common stock of issuers that have historically paid periodic dividends or otherwise made distributions to common stockholders. Unlike fixed income securities, dividend payments generally are not guaranteed and so may be discontinued by the issuer at its discretion or because of the issuer’s inability to satisfy its liabilities. Further, an issuer’s history of paying dividends does not guarantee that it will continue to pay dividends in the future. In addition to dividends, under certain circumstances the holders of common stock may benefit from the capital appreciation of the issuer. Common stocks represent the residual ownership interest in the issuer and holders of common stock are entitled to the income and increase in the value of the assets and business of the issuer after all of its debt obligations and obligations to preferred shareholders are satisfied. Common stocks generally have voting rights. Common stocks fluctuate in price in response to many factors including historical and prospective earnings of the issuer, the value of its assets, general economic conditions, interest rates, investor perceptions and market liquidity. Value Investing. The Fund’s portfolio manager will use various value methods in managing its assets. In selecting securities for the Fund, he evaluates the quality of a company’s balance sheet, the level of its cash flows and other measures of a company’s financial condition and profitability. The portfolio manager may also consider other factors, such as a company’s unrecognized asset values, its future growth prospects or its turnaround potential following an earnings disappointment or other business difficulties. The portfolio manager then uses these factors to assess the company’s current worth, basing this assessment on either what he believes a knowledgeable buyer might pay to acquire the entire company or what he thinks the value of the company should be in the stock market. The Fund’s portfolio manager generally invests in securities of companies that are trading significantly below his estimate of the company’s current worth in an attempt to reduce the risk of overpaying for such companies. Seeking long-term growth of capital, he also evaluates the prospects for the market price of the company’s securities to increase over a two- to five-year period toward this estimate. The Investment Adviser’s value approach strives to reduce some of the other risks of investing in the securities of smaller companies (for the Fund’s portfolio taken as a whole) by evaluating other risk factors. For example, its portfolio manager generally attempts to lessen financial risk by buying companies with strong balance sheets and low leverage. While there can be no assurance that this risk-averse value approach will be successful, the Investment Adviser believes that it can reduce some of the risks of investing. Although the Investment Adviser’s approach to security selection seeks to reduce downside risk to the Fund’s portfolio, especially during periods of broad stock market declines, it may also potentially have the effect of limiting gains in strong up markets. Risk Arbitrage. Subject to the Fund’s other policies including investing at least 25% of its assets in the Utilities Industry, the Fund may invest without limitation in securities pursuant to “risk arbitrage” strategies or in other investment funds managed pursuant to such strategies. Risk arbitrage investments are made in securities of companies for which a tender or exchange offer has been made or announced and in securities of companies for which a merger, consolidation, liquidation or reorganization proposal has been announced if, in the judgment of the Investment Adviser, there is a reasonable prospect of total return significantly greater than the brokerage and other transaction expenses involved. Risk arbitrage strategies attempt to exploit merger activity to capture the spread between current market values of securities and their values after successful completion of a merger, restructuring or similar corporate transaction. Transactions associated with risk arbitrage strategies typically involve the purchases or sales of securities in connection with announced corporate actions which may include, but are not limited to, mergers, consolidations, acquisitions, transfers of assets, tender offers, exchange offers, re-capitalizations, liquidations, divestitures, spin-offs and similar transactions. However, a merger or other restructuring or tender or exchange offer anticipated by the Fund and in which it holds an arbitrage position may not be completed on the terms contemplated or within the time frame anticipated, resulting in losses to the Fund. In general, securities which are the subject of such an offer or proposal sell at a premium to their historic market price immediately prior to the announcement of the offer but may trade at a discount or premium to what the stated or appraised value of the security would be if the contemplated transaction were approved or consummated. Such investments may be advantageous when the discount significantly overstates the risk of the contingencies involved; significantly undervalues the securities, assets or cash to be received by shareholders as a result of the contemplated transaction; or fails adequately to recognize the possibility that the offer or proposal may be replaced or superseded by an offer or proposal of greater value. The evaluation of such contingencies requires unusually broad knowledge and experience on the part of the Investment Adviser which must appraise not only the value of the issuer and its component businesses as well as the assets or securities to be received as a result of the contemplated transaction but also the financial resources and business motivation behind the offer and/or the dynamics and business climate when the offer or proposal is in process. Since such investments are ordinarily short-term in nature, they will tend to increase the turnover ratio of the Fund, thereby increasing its brokerage and other transaction expenses. Risk arbitrage strategies may also involve short selling, options hedging and other arbitrage techniques to capture price differentials. Forward Foreign Currency Exchange Contracts. Subject to guidelines of the Board of Trustees, the Fund may enter into forward foreign currency exchange contracts to protect the value of its portfolio against uncertainty in the level of future currency exchange rates between a particular foreign currency and the U.S. dollar or between foreign currencies in which its securities are or may be denominated. The Fund may enter into such contracts on a spot (i.e., cash) basis at the rate then prevailing in the currency exchange market or on a forward basis by entering into a forward contract to purchase or sell currency. A forward contract on foreign currency is an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days agreed upon by the parties from the date of the contract at a price set on the date of the contract. Forward currency contracts (i) are traded in a market conducted directly between currency traders (typically, commercial banks or other financial institutions) and their customers, (ii) generally have no deposit requirements and (iii) are typically consummated without payment of any commissions. The Fund, however, may enter into forward currency contracts requiring deposits or involving the payment of commissions. The Fund expects to invest in forward currency contracts for hedging or currency risk management purposes and not in order to speculate on currency exchange rate movements. The Fund will only enter into forward currency contracts with parties which it believes to be creditworthy. In hedging a specific transaction, the Fund may enter into a forward contract with respect to either the currency in which the transaction is denominated or another currency deemed appropriate by the Investment Adviser. The amount the Fund may invest in forward currency contracts is limited to the amount of its aggregate investments in foreign currencies. The use of forward currency contracts may involve certain risks, including the failure of the counterparty to perform its obligations under the contract, and such use 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. The Fund will only enter into forward currency contracts with parties that the Investment Adviser believes to be creditworthy institutions. Restricted and Illiquid Securities. Subject to the Fund’s other policies including investing at least 25% of its assets in the Utilities Industry, the Fund may invest without limit in securities for which there is no readily available trading market or are otherwise illiquid. Illiquid securities include securities legally restricted as to resale, such as commercial paper issued pursuant to Section 4(a)(2) of the Securities Act of 1933 (the “Securities Act”) and securities eligible for resale pursuant to Rule 144A thereunder. Section 4(a)(2) and Rule 144A securities may, however, be treated as liquid by the Investment Adviser pursuant to procedures adopted by the Board, which require consideration of factors such as trading activity, availability of market quotations and number of dealers willing to purchase the security. If the Fund invests in Rule 144A securities, the level of portfolio illiquidity may be increased to the extent that eligible buyers become uninterested in purchasing such securities. It may be difficult to sell such securities at a price representing the fair value until such time as such securities may be sold publicly. Where registration is required, a considerable period may elapse between a decision to sell the securities and the time when it would be permitted to sell. Thus, the Fund may not be able to obtain as favorable a price as that prevailing at the time of the decision to sell. The Fund may also acquire securities through private placements under which it may agree to contractual restrictions on the resale of such securities. Such restrictions might prevent their sale at a time when such sale would otherwise be desirable. Leveraging. As provided in the 1940 Act and subject to certain exceptions, the Fund may issue senior securities (which may be additional classes of stock, such as preferred shares, or securities representing debt) so long as its total assets, less certain ordinary course liabilities, exceed 300% of the amount of the debt outstanding and exceed 200% of the amount of preferred shares and debt outstanding. The issuance of senior securities would leverage the common shares. The Fund’s participation in certain derivative transactions that have economic leverage embedded in them, as described below, may also leverage the common shares. Although the timing and other terms of the offering of senior securities and the terms of the senior securities would be determined by the Fund’s Board, the Fund expects to primarily invest the proceeds of any senior securities offering in dividend paying or income producing equity or debt securities. The use of leverage magnifies the impact of changes in net asset value, which means that, all else being equal, the use of leverage results in outperformance on the upside and underperformance on the downside. In addition, if the cost of leverage exceeds the return on the securities acquired with the proceeds of leverage, the use of leverage will diminish rather than enhance the return to the Fund. The use of leverage generally increases the volatility of returns to the Fund. Such volatility may increase the likelihood of the Fund having to sell investments in order to meet its obligations to make distributions on the preferred shares or principal or interest payments on debt securities, or to redeem preferred shares or repay debt, when it may be disadvantageous to do so. The Fund’s use of leverage may require it to sell portfolio investments at inopportune times in order to raise cash to redeem preferred shares or otherwise de-leverage so as to maintain required asset coverage amounts or comply with any mandatory redemption terms of any outstanding preferred shares. See “Risk Factors and Special Considerations—Leverage Risk.” In the event the Fund had both outstanding preferred shares and senior securities representing debt at the same time, the Fund’s obligations to pay dividends or distributions and, upon liquidation of the Fund, liquidation payments in respect of its preferred shares would be subordinate to the Fund’s obligations to make any principal and/or interest payments due and owing with respect to its outstanding senior debt securities. Accordingly, the Fund’s issuance of senior securities representing debt would have the effect of creating special risks for the Fund’s preferred shareholders that would not be present in a capital structure that did not include such securities. See “Risk Factors and Special Considerations—Special Risks to Holders of Fixed Rate Preferred Shares.” Subject to the requirements of Rule 18f-4 under the 1940 Act (“Rule 18f-4”), the Fund may enter into derivative transactions including transactions that have economic leverage embedded in them. Rule 18f-4 defines “derivatives transactions” as (1) any swap, security-based swap, futures contract, forward contract, option, any combination of the foregoing, or any similar instrument, under which a 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; and (2) any short sale borrowing. Derivatives transactions entered into by the Fund in compliance with Rule 18f-4 will not be considered senior securities for purposes of computing the asset coverage requirements described above. Economic leverage exists when the Fund achieves the right to a return on a capital base that exceeds the investment which the Fund has contributed to the instrument achieving a return. Derivative transactions that the Fund may enter into and the risks associated with them are described elsewhere in this Annual Report. The Fund cannot assure you that investments in derivative transactions that have economic leverage embedded in them will result in a higher return on its common shares. If the Fund enters into any reverse repurchase agreements or similar financing transactions obligating the Fund to make future payments, the Fund must either treat all such transactions as derivatives transactions for all purposes under Rule 18f-4 or otherwise comply with the asset coverage requirements described above and combine the aggregate amount of indebtedness associated with all such transactions with the aggregate amount of any other senior securities representing indebtedness when calculating the Fund’s asset coverage ratio limit requirements. The asset coverage requirements under section 18 of the 1940 Act and the limits and conditions imposed by Rule 18f-4 may limit or restrict portfolio management. 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. The prices of these lower grade securities are more sensitive to negative developments, such as a decline in the issuer’s revenues or a general economic downturn, than are the prices of higher grade securities. Securities of below investment grade quality—those securities rated below “Baa” by Moody’s or below “BBB” by S&P (or unrated securities considered by the Investment Adviser to be of comparable quality)—are predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal when due and therefore involve a greater risk of default. Securities rated below investment grade commonly are referred to as “junk bonds” or “high yield” securities and generally pay a premium above the yields of U.S. government securities or securities of investment grade issuers because they are subject to greater risks than these securities. These risks, which reflect their speculative character, include the following:
| ● | greater volatility;
| ● | greater credit risk and risk of default;
| ● | 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.
In addition, the market value of securities in lower grade categories is more volatile than that of higher quality securities, and the markets in which such lower rated or unrated securities are traded are more limited than those in which higher rated securities are traded. The existence of limited markets may make it more difficult for the Fund to obtain accurate market quotations for purposes of valuing its portfolio and calculating its net asset value. Moreover, the lack of a liquid trading market may restrict the availability of securities for the Fund to purchase and may also have the effect of limiting the ability of the Fund to sell securities at their fair value to respond to changes in the economy or the financial markets. Ratings are relative, subjective and 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. Non-investment grade and unrated securities of comparable quality 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 bonds 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 interest currently. Any interest rate increases in the future could cause the value of the Fund to decrease. Recently, inflation levels have been at their highest point in nearly 40 years and the Federal Reserve has been engaged in a campaign to raise certain benchmark interest rates in an effort to combat inflation. As inflation increases, the real value of the Fund’s common stock and distributions therefore may decline. The Fund may purchase securities of companies that are experiencing significant financial or business difficulties, including companies involved in bankruptcy or other reorganization and liquidation proceedings. Although such investments may result in significant financial returns to the Fund, they involve a substantial degree of risk. The level of analytical sophistication, both financial and legal, necessary for successful investments in issuers experiencing significant business and financial difficulties is unusually high. There can be no assurance that the Fund will correctly evaluate the value of the assets collateralizing its investments or the prospects for a successful reorganization or similar action. In any reorganization or liquidation proceeding relating to a portfolio investment, the Fund may lose all or part of its investment or may be required to accept collateral with a value less than the amount of the Fund’s initial investment. As part of its investments in non-investment grade securities (i.e., subject to the 10% cap), the Fund may invest in the securities of issuers in default. The Fund invests in securities of issuers in default only when the Investment Adviser believes that such issuers will honor their obligations and emerge from bankruptcy protection and that the value of such issuers’ securities will appreciate. By investing in the 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 these securities will not otherwise appreciate. In addition to using statistical rating agencies and other sources, the Investment Adviser will also perform its own analysis of issuers in seeking investments that it believes to be underrated (and thus higher yielding) in light of the financial condition of the issuer. Its analysis of issuers may include, among other things, current and anticipated cash flow and borrowing requirements, value of assets in relation to historical cost, strength of management, responsiveness to business conditions, credit standing and current anticipated results of operations. In selecting investments for the Fund, the Investment Adviser may also consider general business conditions, anticipated changes in interest rates and the outlook for specific industries. Subsequent to its purchase by the Fund, an issue of securities may cease to be rated or its rating may be reduced. In addition, it is possible that statistical rating agencies might change their ratings of a particular issue to reflect subsequent events on a timely basis. Moreover, such ratings do not assess the risk of a decline in market value. None of these events will require the sale of the securities by the Fund, although the Investment Adviser will consider these events in determining whether the Fund should continue to hold the securities. Fixed income securities, including non-investment grade securities and comparable unrated securities, frequently have call or buy-back features that permit their issuers to call or repurchase the securities from their holders, such as the Fund. If an issuer exercises these rights during periods of declining interest rates, the Fund may have to replace the security with a lower yielding security, thus resulting in a decreased return for the Fund. The market for non-investment grade and comparable unrated securities has at various times, particularly during times of economic recession, experienced substantial reductions in market value and liquidity. Past recessions have adversely affected the ability of certain issuers of such securities to repay principal and pay interest thereon. The market for those securities could react in a similar fashion in the event of any future economic recession. Options. The Fund may purchase or sell, i.e., write, options on securities, securities indices and foreign currencies which are listed on a national securities exchange or in the over-the-counter (“OTC”) market as a means of achieving additional return or of hedging the value of the Fund’s portfolio. A call option is a contract that, in return for a premium, gives the holder of the option the right to buy from the writer of the call option the security or currency underlying the option at a specified exercise price at any time during the term of the option. The writer of the call option has the obligation, upon exercise of the option, to deliver the underlying security or currency upon payment of the exercise price during the option period. A put option is the reverse of a call option, giving the holder of the option the right, in return for a premium, to sell the underlying security to the writer, at a specified price, and obligating the writer to purchase the underlying security from the holder upon exercise of the exercise price. The Fund will write covered call options in order to receive additional income in the form of premiums which it is paid for writing options, and for hedging purposes in order to protect against possible declines in the market values of the stocks or convertible securities held in its portfolio. If the Fund has written an option, it may terminate its obligation by effecting a closing purchase transaction. This is accomplished by purchasing an option of the same series as the option previously written. However, with respect to exchange-traded options, once the Fund has been assigned an exercise notice, the Fund will be unable to effect a closing purchase transaction. Similarly, if the Fund is the holder of an option it may liquidate its position by effecting a closing sale transaction on an exchange. This is accomplished by selling an option of the same series as the option previously purchased. There can be no assurance that either a closing purchase or sale transaction can be effected when the Fund so desires. The Fund will realize a profit from a closing transaction if the price of the transaction is less than the premium received from writing the option or is more than the premium paid to purchase the option; the Fund will realize a loss from a closing transaction if the price of the transaction is more than the premium received from writing the option or is less than the premium paid to purchase the option. Since call option prices generally reflect increases in the price of the underlying security, any loss resulting from the repurchase of a call option may also be wholly or partially offset by unrealized appreciation of the underlying security, and any gain resulting from the repurchase of a call option may also be wholly or partially offset by unrealized depreciation of the underlying security. Other principal factors affecting the market value of a put or a call option include supply and demand, prevailing interest rates, the current market price and price volatility of the underlying security, and the time remaining until the expiration date of the option. Gains and losses on investments in options depend, in part, on the ability of the Investment Adviser to predict correctly the effect of these factors. The use of options cannot serve as a complete hedge since the price movement of securities underlying the options will not necessarily follow the price movements of the portfolio securities subject to the hedge. An option position may be closed out only on an exchange which provides a secondary market for an option of the same series or in a private transaction. Although the Fund will generally purchase or write only those options for which there appears to be an active secondary market, there is no assurance that a liquid secondary market on an exchange will persist for any particular option. In such event, it might not be possible to effect closing transactions in particular options, so that the Fund would have to exercise its options in order to realize any profit and would incur brokerage commissions upon the exercise of call options and upon the subsequent disposition of underlying securities for the exercise of put options. If the Fund, as a covered call option writer, is unable to effect a closing purchase transaction in a secondary market, it will not be able to sell the underlying security until the option expires or it delivers the underlying security upon exercise or otherwise covers the position. The sale of covered call options may also be used by the Fund to reduce the risks associated with individual investments and to increase total investment return. A call option is “covered” if the Fund owns the underlying instrument covered by the call or has an absolute and immediate right to acquire that instrument without additional cash consideration (or for additional cash consideration held in a segregated account by its custodian) upon conversion or exchange of other instruments held in its portfolio. A call option is also covered if the Fund holds a call option on the same instrument as the call option written where the exercise price of the call option held is (i) equal to or less than the exercise price of the call option written or (ii) greater than the exercise price of the call option written if the difference is maintained by the Fund in cash, U.S. government securities or other high- grade short-term obligations in a segregated account with its custodian. A put option is “covered” if the Fund maintains cash or other liquid securities with a value equal to the exercise price in a segregated account with its custodian, or else holds a put option on the same instrument as the put option written where the exercise price of the put option held is equal to or greater than the exercise price of the put option written. To the extent that the Fund purchases options pursuant to a hedging strategy, the Fund will be subject to the following additional risks. If a put or call option purchased by the Fund is not sold when it has remaining value, and if the market price of the underlying security remains equal to or greater than the exercise price (in the case of a put), or remains less than or equal to the exercise price (in the case of a call), the Fund will lose its entire investment in the option. Where a put or call option on a particular security is purchased to hedge against price movements in that or a related security, the price of the put or call option may move more or less than the price of the security. If restrictions on exercise are imposed, the Fund may be unable to exercise an option it has purchased. If the Fund is unable to close out an option that it has purchased on a security, it will have to exercise the option in order to realize any profit, or the option may expire worthless. Futures Contracts and Options on Futures. The Fund may purchase and sell financial futures contracts and options thereon which are traded on a commodities exchange or board of trade for certain hedging, yield enhancement and risk management purposes. A financial futures contract is an agreement to purchase or sell an agreed amount of securities or currencies at a set price for delivery in the future. These futures contracts and related options may be on debt securities, financial indices, securities indices, U.S. government securities and foreign currencies. The Investment Adviser has claimed an exclusion from the definition of the term “commodity pool operator” under the Commodity Exchange Act. When Issued, Delayed Delivery Securities and Forward Commitments. The Fund may enter into forward commitments for the purchase or sale of securities, including on a “when issued” or “delayed delivery” basis, in excess of customary settlement periods for the type of security involved. In some cases, a forward commitment may be conditioned upon the occurrence of a subsequent event, such as approval and consummation of a merger, corporate reorganization or debt restructuring (i.e., a when, as and if issued security). When such transactions are negotiated, the price is fixed at the time of the commitment, with payment and delivery taking place in the future, generally a month or more after the date of the commitment. While it will only enter into a forward commitment with the intention of actually acquiring the security, the Fund may sell the security before the settlement date if it is deemed advisable by the Investment Adviser. Securities purchased under a forward commitment are subject to market fluctuation, and no interest (or dividends) accrues to the Fund prior to the settlement date. Short Sales. The Fund may make short sales of securities. A short sale is a transaction in which the Fund sells a security it does not own in anticipation that the market price of that security will decline. The market value of the securities sold short of any one issuer will not exceed either 10% of the Fund’s total assets or 5% of such issuer’s voting securities. The Fund also will not make a short sale, if, after giving effect to such sale, the market value of all securities sold short exceeds 25% of the value of its total assets or the Fund’s aggregate short sales of a particular class of securities exceeds 25% of the outstanding securities of that class. The Fund may also make short sales “against the box” without respect to such limitations. In this type of short sale, at the time of the sale, the Fund owns, or has the immediate and unconditional right to acquire at no additional cost, the identical security. The Fund expects to make short sales both to obtain capital gains from anticipated declines in securities and as a form of hedging to offset potential declines in long positions in the same or similar securities. The short sale of a security is considered a speculative investment technique. Short sales “against the box” may be subject to special tax rules, one of the effects of which may be to accelerate income to the Fund. When the Fund makes a short sale, it must borrow the security sold short and deliver it to the broker-dealer through which it made the short sale in order to satisfy its obligation to deliver the security upon conclusion of the sale. The Fund may have to pay a fee to borrow particular securities and is often obligated to deliver any payments received on such borrowed securities, such as dividends. If the price of the security sold short increases between the time of the short sale and the time the Fund replaces the borrowed security, the Fund will incur a loss; conversely, if the price declines, the Fund will realize a capital gain. Any gain will be decreased, and any loss will be increased, by the transaction costs incurred by the Fund, including the costs associated with providing collateral to the broker-dealer (usually cash, U.S. government securities or other highly liquid debt securities) and the maintenance of collateral with its custodian. Although the Fund’s gain is limited to the price at which it sold the security short, its potential loss is theoretically unlimited. Other Derivative Instruments. The Fund may also utilize other types of derivative instruments, primarily for hedging or risk management purposes. These instruments include futures, forward contracts, options on such contracts and interest rate, total return and other kinds of swaps. Limitations on the Purchase and Sale of Futures Contracts, Certain Options, and Swaps. Subject to the guidelines of the Board, the Fund may engage in “commodity interest” transactions (generally, transactions in futures, certain options, certain currency transactions, and certain types of swaps) only for bona fide hedging or other permissible transactions in accordance with the rules and regulations of the Commodity Futures Trading Commission (“CFTC”). Pursuant to amendments by the CFTC to Rule 4.5 under the Commodity Exchange Act (“CEA”), the Investment Adviser has filed a notice of exemption from registration as a “commodity pool operator” with respect to the Fund. The Fund and the Investment Adviser are therefore not subject to registration or regulation as a commodity pool operator under the CEA. In addition, certain trading restrictions are applicable to the Fund as a result of this status. These trading restrictions permit the Fund to engage in commodity interest transactions that include (i) “bona fide hedging” transactions, as that term is defined and interpreted by the CFTC and its staff, without regard to the percentage of the Fund’s assets committed to margin and options premiums and (ii) non-bona fide hedging transactions, provided that the Fund does not enter into such non-bona fide hedging transactions if, immediately thereafter, either (a) the sum of the amount of initial margin deposits on the Fund’s existing futures positions or swaps positions and option or swaption premiums would exceed 5% of the market value of the Fund’s liquidating value, after taking into account unrealized profits and unrealized losses on any such transactions, or (b) the aggregate net notional value of the Fund’s commodity interest transactions would not exceed 100% of the market value of the Fund’s liquidating value, after taking into account unrealized profits and unrealized losses on any such transactions. In addition to meeting one of the foregoing trading limitations, the Fund may not market itself as a commodity pool or otherwise as a vehicle for trading in the futures, options or swaps markets. Therefore, in order to claim the Rule 4.5 exemption, the Fund is limited in its ability to invest in commodity futures, options, and certain types of swaps (including securities futures, broad based stock index futures, and financial futures contracts). As a result, the Fund is more limited in its ability to use these instruments than in the past, and these limitations may have a negative impact on the ability of the Investment Adviser to manage the Fund, and on the Fund’s performance. If the Investment Adviser was required to register as a commodity pool operator with respect to the Fund, compliance with additional registration and regulatory requirements would increase Fund expenses. Other potentially adverse regulatory initiatives could also develop. Risks of Currency Transactions. Currency transactions are also subject to risks different from those of other portfolio transactions. Because currency control is of great importance to the issuing governments and influences economic planning and policy, purchases and sales of currency and related instruments can be adversely affected by government exchange controls, limitations or restrictions on repatriation of currency, and manipulation, or exchange restrictions imposed by governments. These forms of governmental action can result in losses to the Fund if it is unable to deliver or receive currency or monies in settlement of obligations and could also cause hedges it has entered into to be rendered useless, resulting in full currency exposure and incurring transaction costs. Repurchase Agreements. Repurchase agreements may be seen as loans by the Fund collateralized by underlying debt securities. Under the terms of a typical repurchase agreement, the Fund would acquire an underlying debt obligation for a relatively short period (usually not more than one week) subject to an obligation of the seller to repurchase, and the Fund to resell, the obligation at an agreed price and time. This arrangement results in a fixed rate of return to the Fund that is not subject to market fluctuations during the holding period. The Fund bears a risk of loss in the event that the other party to a repurchase agreement defaults on its obligations and the Fund is delayed in or prevented from exercising its rights to dispose of the collateral securities, including the risk of a possible decline in the value of the underlying securities during the period in which it seeks to assert these rights. The Investment Adviser, acting under the supervision of the Board of Trustees, reviews the creditworthiness of those banks and dealers with which the Fund enters into repurchase agreements to evaluate these risks and monitors on an ongoing basis the value of the securities subject to repurchase agreements to ensure that the value is maintained at the required level. The Fund will not enter into repurchase agreements with the Investment Adviser or any of its affiliates. Swaps. The Fund may enter into total rate of return, credit default 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. These transactions generally provide for the transfer from one counterparty to another of certain risks inherent in the ownership of a financial asset such as a common stock or debt instrument. Such risks include, among other things, the risk of default and insolvency of the obligor of such asset, the risk that the credit of the obligor or the underlying collateral will decline or the risk that the common stock of the underlying issuer will decline in value. The transfer of risk pursuant to a derivative of this type may be complete or partial, and may be for the life of the related asset or for a shorter period. These derivatives may be used as a risk management tool for a pool of financial assets, providing the Fund with the opportunity to gain or reduce exposure to one or more reference securities or other financial assets (each, a “Reference Asset”) without actually owning or selling such assets in order, for example, to increase or reduce a concentration risk or to diversify a portfolio. Conversely, these derivatives may be used by the Fund to reduce exposure to an owned asset without selling it. Because the Fund would not own the Reference Assets, the Fund may not have any voting rights with respect to the Reference Assets, and in such cases all decisions related to the obligors or issuers of the Reference Assets, including whether to exercise certain remedies, will be controlled by the swap counterparties. Total rate of return swap agreements are contracts in which one party agrees to make periodic payments to another party based on the change in market value of the assets underlying the contract, which may include a specified security, basket of securities or securities indices during the specified period, in return for periodic payments based on a fixed or variable interest rate or the total return from other underlying assets. A credit default swap consists of an agreement between two parties in which the “buyer” agrees to pay to the “seller” a periodic stream of payments over the term of the contract and the seller agrees to pay the buyer the par value (or other agreed-upon value) of a referenced debt obligation upon the occurrence of a credit event with respect to the issuer of the referenced debt obligation. Generally, a credit event means bankruptcy, failure to pay, obligation acceleration or modified restructuring. The Fund may be either the buyer or seller in a credit default swap. As the buyer in a credit default swap, the Fund would pay to the counterparty the periodic stream of payments. If no default occurs, the Fund would receive no benefit from the contract. As the seller in a credit default swap, the Fund would receive the stream of payments but would be subject to exposure on the notional amount of the swap, which it would be required to pay in the event of a credit event with respect to the issuer of the referenced debt obligation. Accordingly, if the Fund sells a credit default swap (or a credit default index swap), it intends at all times to segregate or designate on its books and records liquid assets in an amount at least equal to the notional amount of the swap (i.e., the cost of payment to the buyer if a credit event occurs). The Fund may also enter into equity contract for difference swap transactions. In an equity contract for difference swap, a set of future cash flows is exchanged between two counterparties. One of these cash flow streams will typically be based on a reference interest rate combined with the performance of a notional value of shares of a stock. The other will be based on the performance of the shares of a stock. Depending on the general state of short-term interest rates and the returns on the Fund’s portfolio securities at the time an equity contract for difference swap transaction reaches its scheduled termination date, there is a risk that the Fund will not be able to obtain a replacement transaction or that the terms of the replacement will not be as favorable as on the expiring transaction. Total rate of return swaps and similar derivatives are subject to many risks, including the possibility that the market will move in a manner or direction that would have resulted in gain for the Fund had the swap or other derivative not been utilized (in which case it would have been better had the Fund not engaged in the hedging transactions), the risk of imperfect correlation between the risk sought to be hedged and the derivative transactions utilized, the possible inability of the counterparty to fulfill its obligations under the swap and potential illiquidity of the hedging instrument utilized, which may make it difficult for the Fund to close out or unwind one or more hedging transactions. Total rate of return swaps and related derivatives are a relatively recent development in the financial markets. Consequently, there are certain legal, tax and market uncertainties that present risks in entering into such arrangements. There is currently little or no case law or litigation characterizing total rate of return swaps or related derivatives, interpreting their provisions, or characterizing their tax treatment. In addition, additional regulations and laws may apply to these types of derivatives that have not previously been applied. There can be no assurance that future decisions construing similar provisions to those in any swap agreement or other related documents or additional regulations and laws will not have an adverse effect on the Fund that utilizes these instruments. The Fund will monitor these risks and seek to utilize these instruments in a manner that does not lead to undue risk regarding the tax or other structural elements of the Fund. The Fund will not invest in these types of instruments if the Reference Assets are commodities except for bona fide hedging or risk management purposes. Convertible Securities. A convertible security is a bond, debenture, note, stock or other similar security that may be converted into or exchanged for a prescribed amount of common stock or other equity security of the same or a different issuer within a particular period of time at a specified price or formula. Before conversion, convertible securities have characteristics similar to non-convertible debt securities in that they ordinarily provide a stream of income with generally higher yields than those of common stock of the same or similar issuers. Convertible securities are senior in rank to common stock in a corporation’s capital structure and, therefore, generally entail less risk than the corporation’s common stock, although the extent to which such risk is reduced depends in large measure upon the degree to which the convertible security sells above its value as a fixed income security. See “Risk Factors and Special Considerations—Convertible Securities Risk.” Temporary Defensive Investments. Although under normal market conditions at least 80% of the Fund’s assets will consist of common stock and other debt or equity securities of foreign and domestic companies involved in the Utilities Industry and securities of companies in other industries that are expected to periodically generate or accrue income, when a temporary defensive posture is believed by the Investment Adviser to be warranted (“temporary defensive periods”), the Fund may without limitation hold cash or invest its assets in money market instruments and repurchase agreements in respect of those instruments. The money market instruments in which the Fund may invest are obligations of the U.S. government, its agencies or instrumentalities; commercial paper rated A-1 or higher by S&P or Prime-1 by Moody’s; and certificates of deposit and bankers’ acceptances issued by domestic branches of U.S. banks that are members of the Federal Deposit Insurance Corporation. During temporary defensive periods, the Fund may also invest to the extent permitted by applicable law in shares of money market mutual funds. Money market mutual funds are investment companies and the investments in those companies by the Fund are in some cases subject to applicable law. As a shareholder in a mutual fund, the Fund will bear its ratable share of its expenses, including management fees, and will remain subject to payment of the fees to the Investment Adviser, with respect to assets so invested. The Fund may find it more difficult to achieve the long-term growth of capital component of its investment objective during temporary defensive periods. Loans of Portfolio Securities. To increase income, the Fund may lend its portfolio securities to securities broker-dealers or financial institutions if the loan is collateralized in accordance with applicable regulatory requirements. If the borrower fails to maintain the requisite amount of collateral, the loan automatically terminates and the Fund could use the collateral to replace the securities while holding the borrower liable for any excess of replacement cost over the value of the collateral. As with any extension of credit, there are risks of delay in recovery and in some cases even loss of rights in collateral should the borrower of the securities violate the terms of the loan or fail financially. There can be no assurance that borrowers will not fail financially. On termination of the loan, the borrower is required to return the securities to the Fund, and any gain or loss in the market price during the loan would inure to the Fund. If the other party to the loan petitions for bankruptcy or becomes subject to the United States Bankruptcy Code, the law regarding the rights of the Fund is unsettled. As a result, under extreme circumstances, there may be a restriction on the Fund’s ability to sell the collateral and the Fund would suffer a loss. Investment Restrictions. The Fund has adopted certain investment limitations designed to limit investment risk and maintain portfolio diversification. These limitations are fundamental and may not be changed without the approval of the holders of a majority, as defined in the 1940 Act, of the outstanding voting securities of the Fund (voting together as a single class). In addition, pursuant to the statements of preferences of the Series A Preferred Shares and the Series B Preferred Shares, a majority, as defined in the 1940 Act, of the outstanding preferred shares of the Fund (voting separately as a single class) is also required to change a fundamental policy. The Fund may become subject to rating agency guidelines that are more limiting than its current investment restrictions in order to obtain and maintain a desired rating on its preferred shares, if any. Neither the Fund’s investment objective nor, except as expressly provided in this Annual Report, any of its policies, is fundamental, and each may be modified by the Board without shareholder approval. Portfolio Turnover. Portfolio turnover generally involves expense to the Fund, including brokerage commissions or dealer mark-ups and other transaction costs on the sale of securities and reinvestment in other securities. The portfolio turnover rate is computed by dividing the lesser of the amount of the securities purchased or securities sold by the average monthly value of securities owned during the year (excluding securities whose maturities at acquisition were one year or less). Higher portfolio turnover may decrease the after-tax return to individual investors in the Fund to the extent it results in a decrease of the long-term capital gains portion of distributions to shareholders. The Fund’s portfolio turnover rates for the fiscal years ended December 31, 2022 and December 31, 2023 was 6% and 3%, respectively. |  |  |  |  |  |  |  |  |
Risk Factors [Table Text Block] |  |  |  |  |  |  |  |  |  | RISK FACTORS AND SPECIAL CONSIDERATIONS Investors should consider the following risk factors and special considerations associated with investing in the Fund: Market Risk. The market price of securities owned by the Fund may go up or down, sometimes rapidly or unpredictably. Securities may decline in value due to factors affecting securities markets generally or particular industries represented in the securities markets. The value of a security may decline due to general market conditions which are not specifically related to a particular company, such as real or perceived adverse economic conditions, changes in the general outlook for corporate earnings, changes in interest or currency rates, adverse changes to credit markets or adverse investor sentiment generally. The value of a security may also decline due to factors which affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry. During a general downturn in the securities markets, multiple asset classes may decline in value simultaneously. Equity securities generally have greater price volatility than fixed income securities. Credit ratings downgrades may also negatively affect securities held by the Fund. Even when markets perform well, there is no assurance that the investments held by the Fund will increase in value along with the broader market. In addition, market risk includes the risk that geopolitical and other events will disrupt the economy on a national or global level. For instance, war, terrorism, market manipulation, government defaults, government shutdowns, political changes or diplomatic developments, public health emergencies (such as the spread of infectious diseases, pandemics and epidemics) and natural/environmental disasters can all negatively impact the securities markets, which could cause the Fund to lose value. These events could reduce consumer demand or economic output, result in market closures, travel restrictions or quarantines, and significantly adversely impact the economy. 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, has in the past resulted, and may in the future result, in a government shutdown, which could have an adverse impact on the Fund’s investments and operations. Additional and/or prolonged U.S. federal 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. Governmental and quasi-governmental authorities and regulators throughout the world have previously responded to serious economic disruptions with a variety of significant fiscal and monetary policy changes, including, but not limited to, direct capital infusions into companies, new monetary programs and dramatically lower interest rates. An unexpected or sudden reversal of these policies, or the ineffectiveness of these policies, could increase volatility in securities markets, which could adversely affect the Fund’s investments. Any market disruptions could also prevent the Fund from executing advantageous investment decisions in a timely manner. To the extent that the Fund focuses its investments in a region enduring geopolitical market disruption, it will face higher risks of loss, although the increasing interconnectivity between global economies and financial markets can lead to events or conditions in one country, region or financial market adversely impacting a different country, region or financial market. Thus, investors should closely monitor current market conditions to determine whether the Fund meets their individual financial needs and tolerance for risk. Current market conditions may pose heightened risks with respect to the Fund’s investment in fixed income securities. Central banks such as the Federal Reserve Bank have been increasing interest rates, though this trend has tempered recently as the rate of inflation slows. There is a risk that additional increases in interest rates or a prolonged period of rising interest rates may cause the economy to enter a recession. Any interest rate increases in the future could cause the value of the Fund to decrease. In addition, inflation levels have been at their highest point in nearly 40 years and the Federal Reserve has been engaged in a campaign to raise certain benchmark interest rates in an effort to combat inflation. As inflation increases, the real value of the Fund’s common stock and distributions therefore may decline. Exchanges and securities markets may close early, close late or issue trading halts on specific securities or generally, which may result in, among other things, the Fund being unable to buy or sell certain securities or financial instruments at an advantageous time or accurately price its portfolio investments. Interest Rate Risk Generally. The primary risk associated with dividend-and interest-paying securities is interest rate risk. A decrease in interest rates will generally result in an increase in the investment value of such securities, while increases in interest rates will generally result in a decline in the investment value of such securities. This effect is generally more pronounced for fixed rate securities than for securities whose income rate is periodically reset. General interest rate fluctuations may have a substantial negative impact on the Fund’s investments, the value of the Fund and the Fund’s rate of return. A reduction in the interest or dividend rates on new investments relative to interest or dividend rates on current investments could also have an adverse impact on the Fund’s net investment income. An increase in interest rates could decrease the value of any investments held by the Fund that earn fixed interest or dividend rates, including debt securities, convertible securities, preferred stocks, loans and high-yield bonds, and also could increase interest or dividend expenses, thereby decreasing net income. The magnitude of these fluctuations in the market price of bonds and other income- or dividend-paying 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 net asset value. The Fund may lose money if short-term or long-term interest rates rise sharply in a manner not anticipated by Fund management. To the extent the Fund invests in securities that may be prepaid at the option of the obligor, the sensitivity of such securities to changes in interest rates may increase (to the detriment of the Fund) when interest rates rise. Moreover, because rates on certain floating rate securities typically reset only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be expected to cause some fluctuations in the net asset value of the Fund to the extent that it invests in floating rate securities. These basic principles of bond prices also apply to U.S. government securities. A security backed by the “full faith and credit” of the U.S. government is guaranteed only as to its stated interest rate and face value at maturity, not its current market price. Just like other income- or dividend-paying securities, government-guaranteed securities will fluctuate in value when interest rates change. The Fund’s use of leverage will tend to increase the Fund’s interest rate risk. The Fund may invest in variable and floating rate instruments, which generally are less sensitive to interest rate changes than longer duration fixed rate instruments but may decline in value in response to rising interest rates if, for example, the rates at which they pay interest do not rise as much, or as quickly, as market interest rates in general. Conversely, variable and floating rate instruments generally will not increase in value if interest rates decline. The Fund also may invest in inverse floating rate securities, which may decrease in value if interest rates increase, and which also may exhibit greater price volatility than fixed rate obligations with similar credit quality. To the extent the Fund holds variable or floating rate instruments, a decrease (or, in the case of inverse floating rate securities, an increase) in market interest rates will adversely affect the income received from such securities, which may adversely affect the net asset value of the Fund’s common shares. Central banks such as the Federal Reserve Bank have been increasing interest rates, though this trend has tempered recently as the rate of inflation slows. There is a risk that heightened interest rates may cause the economy to enter a recession. Any such recession would negatively impact the Fund and the investments held by the Fund. These impacts may include:
| ● | severe declines in the Fund’s net asset values;
| ● | inability of the Fund to accurately or reliably value its portfolio;
| ● | inability of the Fund to pay any dividends or distributions;
| ● | inability of the Fund to maintain its status as a registered investment company (“RIC”) under the Internal Revenue Code of 1986, as amended (the “Code”);
| ● | declines in the value of the Fund’s investments;
| ● | increased risk of default or bankruptcy by the companies in which the Fund invests;
| ● | increased risk of companies in which the Fund invests being unable to weather an extended cessation of normal economic activity and thereby impairing their ability to continue functioning as a going concern; and
| ● | limited availability of new investment opportunities.
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. This risk may be elevated compared to historical market conditions because of recent monetary policy measures and the current interest rate environment. Inflation rates may change frequently and significantly as a result of various factors, including unexpected shifts in the domestic or global economy and changes in economic policies, and the Fund’s investments may not keep pace with inflation, which may result in losses to Fund shareholders. As inflation increases, the real value of the Fund’s shares and dividends may decline. In addition, during any periods of rising inflation, interest rates of any debt securities held by the Fund would likely increase, which would tend to further reduce returns to shareholders. This risk is greater for fixed-income instruments with longer maturities. Industry Risks. The Fund invests in foreign and domestic companies involved in the Utilities Industry and, as a result, the value of the common shares will be more susceptible to factors affecting those particular types of companies, including governmental regulation, inflation, cost increases in 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 product development, infrastructure and capital construction programs, including costs associated with compliance with environmental and other regulations. Sector Risk. The Fund concentrates its investments in the Utilities Industry. As a result, the Fund’s investments may be subject to greater risk and market fluctuation than a fund that had securities representing a broader range of investment alternatives. The prices of equity securities issued by certain types of utility companies may change more in response to interest rate changes than the equity securities of other companies. Generally, when interest rates go up, the value of securities issued by these companies goes down. Conversely, when interest rates go down, the value of securities issued by these companies goes up. There is no guarantee that this relationship will hold in the future. Privatization in the Utilities Industry may subject companies to greater competition and losses in profitability. Companies in the Utilities Industry may have difficulty obtaining an adequate return on invested capital, raising capital, or financing large construction programs during periods of inflation or unsettled capital markets. Government Regulation. Companies in certain sectors of the Utilities Industry (such as power generation and distribution) are subject to extensive governmental regulatory requirements. In the United States, most companies in the Utilities Industry are regulated by state and/or federal authorizes. For example, at the federal level in the United States, the Federal Energy Regulatory Commission (“FERC”), the Federal Trade Commission (“FTC”), the SEC and the Nuclear Regulatory Commission (“NRC”) have authority to oversee electric and combination electric and gas utilities. Certain of these regulations that are intended to limit the concentration of ownership and control of companies in these industries may prevent companies in which the Fund invests from making certain investments that they would otherwise make. Other regulations may cause Utilities Industry companies to incur substantial additional costs or lengthy delays in connection with the completion of capital investments or the introduction of new products or services to market. There are substantial differences between the regulatory practices and policies in various jurisdictions, and any given regulatory agency may make major shifts in policy from time to time. There is no assurance that regulatory authorities will, in the future, permit companies to implement rate increases or that such increases will be adequate to permit the payment of dividends on such issuer’s common stocks. Additionally, existing and possible future regulatory legislation may make it even more difficult for companies in the Utilities Industry to obtain adequate relief from rate regulation. Regulatory considerations limit the percentage of the shares of a public utility or utility holding company held by a fund or by an adviser and its affiliates on behalf of all their clients. In particular, approval of the FERC under the Federal Power Act would generally be required for (i) the Fund to acquire and hold 10% or more of the voting securities of any publicly traded public utility or utility holding company, and (ii) for the Fund together with any affiliated fund or other affiliated entity to acquire and hold in the aggregate 20% or more of the voting securities of any publicly traded public utility or utility holding company. Other requirements for FERC or state utility commission approval of the acquisition of voting securities may apply as well. Apart from approval requirements with respect to acquisitions of voting securities, the Fund may choose to limit its ownership of public utility or utility holding company voting securities in order to avoid the imposition of regulatory requirements under federal or state law such as those that attend status as a “holding company” under the Public Utility Holding Company Act of 2005. Similarly, various types of ownership restrictions are imposed by the Federal Communications Commission (“FCC”), on investment in media companies and cellular licensees. For example, the FCC’s broadcast and cable multiple-ownership and cross ownership rules, which apply to the radio, television, and cable industries, provide that investment advisers are deemed to have an “attributable” interest whenever the adviser has the right to determine how five percent or more of the issued and outstanding voting stock of a broadcast company or cable system operator may be voted. These rules limit the number of broadcast stations both locally and nationally that a single entity is permitted to own, operate, or control and prohibit ownership of certain competitive communications providers in the same location. The FCC also applies limited ownership restrictions on cellular licensees serving rural areas. An attributable interest in a cellular company arises from the right to control 20% or more of its voting stock. Attributable interests that may result from the role of the Investment Adviser and its principals in connection with other funds, managed accounts and companies may limit the Fund’s ability to invest in certain mass media and cellular companies. These limitations may unfavorably restrict the ability of the Fund to make certain investments. Deregulation. Changing regulation constitutes one of the key industry-specific risks for the Fund, especially with respect to its investments in traditionally regulated public utilities and partially regulated utility or telecommunications companies. Domestic and foreign regulators may monitor and control such companies’ revenues and costs, and therefore may limit utility profits and dividends paid to investors, which could result in reduced income to the Fund. Regulatory authorities also may restrict a company’s access to new markets, thereby diminishing the company’s long-term prospects. In some jurisdictions certain portions of various utilities functions have been deregulated. Deregulation may eliminate restrictions on profits and dividends of companies, but may also subject these companies to greater risks of loss. Thus, deregulation could have a positive or negative impact on the Fund. The Investment Adviser believes that certain Utilities Industry companies’ fundamentals should continue to improve as the industry undergoes deregulation. The nature of regulation of the Utilities Industry continues to evolve both in the United States and in foreign countries. In recent years, changes in regulation in the United States increasingly have allowed companies in the Utilities Industry to provide services and products outside their traditional geographic areas and lines of business, creating new areas of competition within these industries. In some instances, companies in the Utilities Industry are operating on an unregulated basis. However, a number of companies have failed in their efforts to take advantage of the deregulated environment and are seeking to refocus in their primary business. Nonetheless, because of trends toward deregulation and the evolution of independent producers as well as new entrants to the field of telecommunications, non-regulated providers of utility and telecommunications services have become a significant part of their respective industries. The emergence of competition and deregulation may result in certain companies in the Utilities Industry being able to earn more than their traditional regulated rates of return, while others may be forced to defend their core business from increased competition and may be less profitable. Reduced profitability, as well as new uses of funds (such as for expansion, operations or stock buybacks) could result in cuts in dividend payout rates. The Investment Adviser seeks to take advantage of favorable investment opportunities that may arise from these structural changes. Of course, there can be no assurance that favorable developments will occur in the future. Environmental and Other Regulatory Matters. Companies in the Utilities Industry in which the Fund will invest may be subject to a number of host country statutory and regulatory standards and required approvals relating to energy, labor and environmental laws. Certain permits and regulatory approvals may be required to be obtained for certain investments by companies in which the Fund will invest and failure by such companies to obtain such permits and regulatory approvals could adversely affect the Fund’s investment. Companies also face considerable costs associated with environmental compliance, nuclear waste clean-up and safety regulation. Increasingly, regulators are calling upon electric utilities to bear these added costs, and there is a risk that these costs will not be fully recovered through an increase in revenues. Changing weather patterns and natural disasters affect consumer demand for utility services (e.g., electricity, heat and air conditioning), which, in turn, affects utility revenues. The adoption by a host country of new laws, policies or regulations or changes in the interpretation or application of existing laws, policies and regulations that modify the present regulatory environment could also have an adverse effect on the Fund’s investments. Regulatory risk affects companies in the Utilities Industry in part because governments may be party to private Utilities Industry investments as lessors, customers, regulators or partners. Moreover, for political reasons, governments may control the prices at which companies in the Utilities Industry can sell their products, which can adversely affect the Fund’s investment in such a company. Under the laws of certain countries that are host to Utilities Industry companies in which the Fund may invest, such companies may be required to comply with a number of statutes and regulations during their operation pertaining to environmental controls or restrictions, and the storage, handling, transportation and disposal of hazardous and toxic material, waste or other substances. Compliance with such requirements may be costly and may materially affect the profitability of such companies. For example, governments have been increasing their attention to issues related to greenhouse gas (“GHG”) emissions and climate change, and regulatory measures to limit or reduce GHG emissions are currently in various stages of discussion or implementation. GHG emissions-related regulations could substantially harm energy companies, including by reducing the demand for energy fuels and increasing compliance costs. Failure by such a company to comply with any such statutes or regulations could have adverse effects on its business results and prospects, which could have negative consequences for investors such as the Fund. Foreign Utility Companies. Foreign companies in the Utilities Industry are also subject to regulation, although such regulation may or may not be comparable to regulation in the United States. Foreign companies in the Utilities Industry may be more heavily regulated by their respective governments than companies in the United States and, as in the United States, generally are required to seek government approval for rate increases. In addition, many foreign utilities use fuels that may cause more pollution than those used in the United States, which may require such utilities to invest in pollution control equipment to meet any proposed pollution restrictions. Foreign regulatory systems vary from country to country and may evolve in ways different from regulation in the United States. Additionally, because the effectiveness of the judicial systems in non-U.S. countries varies, the Fund or companies in which it may invest may have difficulty in successfully pursuing claims in the courts of such countries. Privatization, which refers to the trend toward investor ownership of assets rather than government ownership, is expected to occur in newer, faster-growing economies and in mature economies. Of course, there is no assurance that such favorable developments will occur or that investment opportunities in foreign markets will increase. The revenues of domestic and foreign utility companies generally reflect the economic growth and development in the geographic areas in which they do business. Financing. At certain times, including during inflationary periods, companies in the Utilities Industry encounter difficulties in obtaining financing for product development, infrastructure and construction programs. Issuers experiencing such difficulties may also experience lower profitability, which can result in reduced income to the Fund. Historically, companies in the Utilities Industry have also encountered such financing difficulties during inflationary periods, although we cannot assure you that such a relationship will continue and that companies in the Utilities Industry will not encounter financing difficulties during non-inflationary periods. Equipment and Supplies. Companies in the Utilities Industry may face the risk of lengthy delays and increased costs associated with the design, development, construction, licensing and operation of their facilities or sale of their products. Moreover, technological innovations may render existing plants, equipment or products obsolete. Increased costs and a reduction in the availability of fuel (such as oil, coal, nuclear or natural gas) also may adversely affect the profitability of utility companies. Electric utilities may be burdened by unexpected increases in fuel and other operating costs. They may also be negatively affected when long-term interest rates rise. Long-term borrowings are used to finance most utility investments, and rising interest rates lead to higher financing costs and reduced earnings. Investments in certain kinds of utility companies are also subject to certain additional risks. Electric. Certain of the issuers of securities held in the Fund’s portfolio may own or operate nuclear generating facilities. Governmental authorities may from time to time review existing policies and impose additional requirements governing the licensing, construction and operation of nuclear power plants. In the past, nuclear generating projects in the electric utility industry have experienced substantial cost increases, construction delays and licensing difficulties. These have been caused by various factors, including inflation, high financing costs, required design changes and rework, allegedly faulty construction, objections by groups and governmental officials, limits on the ability to obtain financing, reduced forecasts of energy requirements and economic conditions. This experience indicates that the risk of significant cost increases, delays and licensing difficulties remain present until completion and achievement of commercial operation of any nuclear project. Also, nuclear generating units in service have experienced unplanned outages or extensions of scheduled outages due to equipment problems or new regulatory requirements sometimes followed by a significant delay in obtaining regulatory approval to return to service. A major accident at a nuclear plant anywhere could cause the imposition of limits or prohibitions on the operation, construction or licensing of nuclear units. Prolonged changes in climatic conditions can also have a significant impact on both the revenues of an electric and gas utility as well as its expenses. The construction and operation of nuclear power facilities are subject to strict scrutiny by, and evolving regulations of, the Nuclear Regulatory Commission and state agencies which have comparable jurisdiction. Strict scrutiny might result in higher operating costs and higher capital expenditures, with the risk that the regulators may disallow inclusion of these costs in rate authorizations or the risk that a company may not be permitted to operate or complete construction of a facility. In addition, operators of nuclear power plants may be subject to significant costs for disposal of nuclear fuel and for decommissioning such plants. The rating agencies look closely at the business profile of utilities. Ratings for companies are expected to be affected to a greater extent in the future by how their asset base is utilized. Electric utility companies that focus more on the generation of electricity may be assigned less favorable ratings as this business is expected to be competitive and the least regulated. On the other hand, companies that focus on transmission and distribution, which is expected to be the least competitive and the more regulated part of the business, may see higher ratings given the greater predictability of cash flow. A number of states are considering or have enacted deregulation proposals. The introduction of competition into the industry as a result of such deregulation has at times resulted in lower revenue, lower credit ratings, increased default risk, and lower electric utility security prices. Such increased competition may also cause long-term contracts, which electric utilities previously entered into to buy power, to become “stranded assets” which have no economic value. Any loss associated with such contracts must be absorbed by ratepayers and investors. In addition, some electric utilities have acquired electric utilities overseas to diversify, enhance earnings and gain experience in operating in a deregulated environment. In some instances, such acquisitions have involved significant borrowings, which have burdened the acquirer’s balance sheet. There is no assurance that current deregulation proposals will be adopted. However, deregulation in any form could significantly impact the electric utilities industry. Following deregulation of the energy markets in certain states, a number of companies have engaged in energy trading and incurred substantial losses. Certain of these energy trading businesses have been accused of employing improper accounting practices and have been required to make significant restatements of their financial results. In addition, several energy companies have been accused of attempting to manipulate the price and availability of energy in certain states. Telecommunications. The telecommunications industry today includes both traditional telephone companies with a history of broad market coverage and highly regulated businesses and cable companies, which began as small, lightly regulated businesses focused on limited markets. Today these two historically different businesses are converging in an industry which is trending toward larger, competitive, national and international markets with an emphasis on deregulation. Companies that distribute telephone services and provide access to the telephone networks still comprise the greatest portion of this segment, but non-regulated activities such as cellular telephone services, paging, data processing, equipment retailing, computer software and hardware services are becoming increasingly significant components as well. The presence of unregulated companies in this industry and the entry of traditional telephone companies into unregulated or less regulated businesses provide significant investment opportunities with companies which may increase their earnings at faster rates than had been allowed in traditional regulated businesses. Still, increasing competition, technological innovations and other structural changes could adversely affect the profitability of such utilities and the growth rate of their dividends. Given mergers and proposed legislation and enforcement changes, it is likely that both traditional telephone companies and cable companies will continue to provide an expanding range of utility services to residential, corporate and governmental customers. Gas. Gas transmission companies and gas distribution companies are also undergoing significant changes. In the United States, interstate transmission companies are regulated by the FERC, which began reducing its regulation of the industry in the 1980’s. Many companies have diversified into oil and gas exploration and development, making returns more sensitive to energy prices. In the recent decade, gas utility companies have been adversely affected by disruptions in the oil industry, including related to political conditions in oil producing regions (such as the Middle East), by increased concentration and competition, and by differing approaches to energy policy in the United States, including increased incentives for the exploration and production of alternative energy and climate-related programs, revocation of federal permits for, and public opposition to, natural gas pipelines, such as the cross-border operation permit for the Keystone XL Pipeline and other policy decisions that favor alternative energy sources. The extension of these policies, or the adoption of similar policies, could adversely affect the financial performance of gas transmission and distribution companies. Prolonged changes in climatic conditions can also have a significant impact on both the revenues and expenses of a gas utility. Natural gas is the cleanest of the hydrocarbon fuels, and this may result in incremental shifts in fuel consumption toward natural gas and away from oil and coal, even for electricity generation. However, technological or regulatory changes within the industry may delay or prevent this result. Water. In the case of the water utility sector, the industry is highly fragmented, and most water supply companies find themselves in mature markets, although upgrading of fresh water and waste water systems is an expanding business. Technology and Competitive Risks. The introduction and phase-in of new technologies can affect a utility company’s competitive strength. The race by long-distance telephone providers to incorporate fiber optic technology is one example of competitive risk within the utilities industry. The increasing role of independent power producers (IPPs) in the natural gas and electric utility segments of the utilities industry is another example of competitive risk. Typically, IPPs wholesale power to established local providers, but there is a trend toward letting them sell power directly to industrial consumers. Co-generation facilities, such as those of landfill operators that produce methane gas as a byproduct of their core business, pose another competitive challenge to gas and electric utilities. In addition to offering a less expensive source of power, these companies may receive more favorable regulatory treatment than utilities seeking to expand facilities that consume nonrenewable energy sources. Utilities Industry Generally. There can be no assurance that the positive developments noted above, including those relating to privatization and changing regulation, will occur or that risk factors other than those noted above will not develop in the future. Moreover, price disparities within selected utility groups and discrepancies in relation to averages and indices have occurred frequently for reasons not directly related to the general movements or price trends of utility common stocks. Causes of these discrepancies include changes in the overall demand for and supply of various securities (including the potentially depressing effect of new stock offerings), and changes in investment objectives, market expectations or cash requirements of other purchasers and sellers of securities. Cyber and Physical Security Risks. Companies in the Utilities Industry have experienced sabotage to company infrastructure, property and equipment, attempts to breach company operating systems and other similar incidents in the past, which have resulted in shutdowns and/or disruptions in their operations. For example, in May 2021, a U.S. fuel pipeline operator was the target of a ransomware attack, which resulted in the shutdown of a massive oil pipeline system that supplies the eastern United States. Recently, in September 2022, several subsea explosions ruptured the Nord Stream I pipeline and one Nordstream II pipe, causing a substantial disruption in the delivery of natural gases under the Baltic Sea. Several counties continue to investigate the incident, but several, including Sweden, have concluded the explosions were caused by grievous sabotage. Companies in the Utilities Industry may continue to be subject to attempts to gain unauthorized access to or through their operating systems and physical attacks on industry and company infrastructure, property and equipment. Any physical damage, system failure, cybersecurity breach, ransomware attack, system disruption or other material harm could interrupt or delay operations and impact a company in the Utilities Industry’s ability to manage its operations and report financial performance, which could have a materially adverse effect on existing and future business. These and other developments may adversely impact the value of the Fund’s investments in companies in the Utilities Industry. Leveraged Capital Structures. It is expected that Utilities Industry companies in which the Fund will invest may employ considerable leverage, a significant portion of which may be at floating interest rates. As a result, a Utilities Industry company may be subject to increased exposure to adverse economic factors such as a significant rise in interest rates, a severe downturn in the economy or deterioration in the condition of such company or its industry. 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 net asset value of the Fund may at any point in time be less than the net asset value of the Fund at the time the shareholder invested in the Fund, even after taking into account any reinvestment of distributions. Common Stock Risk. Common stock of an issuer in the Fund’s portfolio may decline in price for a variety of reasons, including if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock in which the Fund invests is structurally subordinated as to income and residual value to preferred stock, bonds and other debt instruments in a company’s capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stock or debt instruments of such issuers. In addition, while common stock has historically generated higher average returns than fixed income securities, common stock has also experienced significantly more volatility in those returns. Preferred Stock Risk. 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 shareholders. 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 se 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 U.S. federal income tax or securities laws. A redemption by the issuer may negatively impact the return of the security held by the Fund.
Convertible Securities Risk. Convertible securities generally offer lower interest or dividend yields than non-convertible securities of similar quality. The market values of convertible securities tend to decline as interest rates increase and, conversely, to increase as interest rates decline. In the absence of adequate anti-dilution provisions in a convertible security, dilution in the value of the Fund’s holding may occur in the event the underlying stock is subdivided, additional equity securities are issued for below market value, a stock dividend is declared or the issuer enters into another type of corporate transaction that has a similar effect. Merger Arbitrage Risk. The Fund may invest in securities of companies for which a tender or exchange offer has been made or announced, and in securities of companies for which a merger, consolidation, liquidation or reorganization proposal has been announced. The principal risk of such investments is that certain of such proposed transactions may be renegotiated, terminated or involve a longer time frame than originally contemplated, in which case the Fund may realize losses. Such risk is sometimes referred to as “merger arbitrage risk.” Among the factors that affect the level of risk with respect to the completion of the transaction are the deal spread and number of bidders, the friendliness of the buyer and seller, the strategic rationale behind the transaction, the existence of regulatory hurdles, the level of due diligence completed on the target company and the ability of the buyer to finance the transaction. If the spread between the purchase price and the current price of the seller’s stock is small, the risk that the transaction will not be completed may outweigh the potential return. If there is very little interest by other potential buyers in the target company, the risk of loss may be higher than where there are back-up buyers that would allow the arbitrageur to realize a similar return if the current deal falls through. Unfriendly management of the target company or change in friendly management in the middle of a deal increases the risk that the deal will not be completed even if the target company’s board has approved the transaction and may involve the risk of litigation expense if the target company pursues litigation in an attempt to prevent the deal from occurring. The underlying strategy behind the deal is also a risk consideration because the less a target company will benefit from a merger or acquisition, the greater the risk. There is also a risk that an acquiring company may back out of an announced deal if, in the process of completing its due diligence of the target company, it discovers something undesirable about such company. In addition, merger transactions are also subject to regulatory risk because a merger transaction often must be approved by a regulatory body or pass governmental antitrust review. All of these factors affect the timing and likelihood that the transaction will close. Even if the Investment Adviser selects announced deals with the goal of mitigating the risks that the transaction will fail to close, such risks may still delay the closing of such transaction to a date later than the Fund originally anticipated, reducing the level of desired return to the Fund. Merger arbitrage positions are also subject to the risk of overall market movements. To the extent that a general increase or decline in equity values affects the stocks involved in a merger arbitrage position differently, the position may be exposed to loss. Finally, merger arbitrage strategies depend for success on the overall volume of global merger activity, which has historically been cyclical in nature. During periods when merger activity is low, it may be difficult or impossible to identify opportunities for profit or to identify a sufficient number of such opportunities to provide balance among potential merger transactions. To the extent that the number of announced deals and corporate reorganizations decreases or the number of investors in such transactions increases, it is possible that merger arbitrage spreads will tighten, causing the profitability of investing in such transactions to diminish, which will in turn decrease the returns to the Fund from such investment activity. Recapitalization Risk. In recapitalizations, a corporation may restructure its balance sheet by selling specific assets, significantly leveraging other assets and creating new classes of equity securities to be distributed, together with a substantial payment in cash or in debt securities, to existing shareholders. In connection with such transactions, there is a risk that the value of the cash and new securities distributed will not be as high as the cost of the Fund’s original investment or that no such distribution will ultimately be made and the value of the Fund’s investment will decline. To the extent an investment in a company that has undertaken a recapitalization is retained by the Fund, the Fund’s risks will generally be comparable to those associated with investments in highly leveraged companies, generally including higher than average sensitivity to (i) short-term interest rate fluctuations, (ii) downturns in the general economy or within a particular industry or (iii) adverse developments within the company itself. Distribution Risk for Equity Income Securities. In selecting equity income securities in which the Fund will invest, the Investment Adviser will consider the issuer’s history of making regular periodic distributions (i.e., dividends) to its equity holders. An issuer’s history of paying dividends, however, does not guarantee that the issuer will continue to pay dividends in the future. The dividend income stream associated with equity income securities generally is not guaranteed and will be subordinate to payment obligations of the issuer on its debt and other liabilities. Accordingly, in the event the issuer does not realize sufficient income in a particular period both to service its liabilities and to pay dividends on its equity securities, it may forgo paying dividends on its equity securities. In addition, because in most instances issuers are not obligated to make periodic distributions to the holders of their equity securities, such distributions or dividends generally may be discontinued at the issuer’s discretion. Dividend-producing equity income securities, in particular those whose market price is closely related to their yield, may exhibit greater sensitivity to interest rate changes. See “—Fixed Income Securities Risks—Interest Rate Risk.” The Fund’s investments in dividend-producing equity income securities may also limit its potential for appreciation during a broad market advance. The prices of dividend-producing equity income securities can be highly volatile. Investors should not assume that the Fund’s investments in these securities will necessarily reduce the volatility of the Fund’s net asset value or provide “protection,” compared to other types of equity income securities, when markets perform poorly. Fixed Income Securities Risks. Fixed 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. See “— General Risks—Interest Rate Risks Generally.”
| ● | 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. To the extent the Fund invests in below investment grade securities, it will be exposed to a greater amount of credit risk than a fund which only invests in investment grade securities. See “—Non-Investment Grade Securities.” In addition, to the extent the Fund uses credit derivatives, such use will expose it to additional risk in the event that the bonds underlying the derivatives default. The degree of credit risk depends on the issuer’s financial condition and on the terms of the securities.
| ● | 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 reinvest in lower yielding securities, resulting in a possible decline in the Fund’s income and distributions to shareholders. This is known as prepayment or “call” risk. Below investment grade securities frequently have call features that allow the issuer to redeem the security at dates prior to its stated maturity at a specified price (typically greater than par) only if certain prescribed conditions are met (“call protection”).
For premium bonds (bonds acquired at prices that exceed their par or principal value) purchased by the Fund, prepayment risk may be enhanced.
| ● | 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 has no set policy regarding portfolio maturity or duration of the fixed-income securities it may hold. The Investment Adviser may seek to adjust the duration or maturity of the Fund’s fixed-income holdings based on its assessment of current and projected market conditions and all other factors that the Investment Adviser deems relevant. 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 net asset value that is expected for every percentage point change in interest rates. The two have an inverse relationship. Duration can be a useful tool to estimate anticipated price changes to a fixed pool of income securities associated with changes in interest rates. For example, a duration of five years means that a 1% decrease in interest rates will increase the net asset value of the portfolio by approximately 5%; if interest rates increase by 1%, the net asset value 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. Prices of securities with longer durations tend to be more sensitive to interest rate changes than securities with shorter durations. In general, a portfolio of securities with a longer duration can be expected to be more sensitive to interest rate changes than a portfolio with a shorter duration. Any decisions as to the targeted duration or maturity of any particular category of investments will be made based on all pertinent market factors at any given time. The Fund may incur costs in seeking to adjust the portfolio average duration or maturity. 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. Corporate Bonds Risk. The market value of a corporate bond generally may be expected to rise and fall inversely with interest rates. The market value of intermediate and longer-term corporate bonds is generally more sensitive to changes in interest rates than is the market value of shorter term corporate bonds. The market value of a corporate bond also may be affected by factors directly related to the issuer, such as investors’ perceptions of the creditworthiness of the issuer, the issuer’s financial performance, perceptions of the issuer in the market place, performance of management of the issuer, the issuer’s capital structure and use of financial leverage and demand for the issuer’s goods and services. Certain risks associated with investments in corporate bonds are described elsewhere in this Annual Report in further detail, including under “— Fixed Income Securities Risks — Credit Risk,” “—Fixed Income Securities Risks—Interest Rate Risk” and “—Fixed Income Securities Risks—Prepayment Risk,” “—General Risks—Inflation Risk” and “—General Risks—Interest Rate Risk Generally.” There is a risk that the issuers of corporate bonds may not be able to meet their obligations on interest or principal payments at the time called for by an instrument. Corporate bonds of below investment grade quality are often high risk and have speculative characteristics and may be particularly susceptible to adverse issuer-specific developments. Corporate bonds of below investment grade quality are subject to the risks described herein under “—Non-Investment Grade Securities.” Non-Investment Grade Securities. The Fund may invest in below investment-grade securities, also known as “high-yield” securities or “junk” bonds. Securities rated below investment grade, which may be preferred stock or debt, are predominantly speculative and involve major risk exposure to adverse conditions. Securities that are rated lower than “BBB” by S&P or lower than “Baa” by Moody’s (or unrated securities considered by the Investment Adviser to be of comparable quality) are referred to in the financial press as “junk bonds” or “high-yield” securities and generally pay a premium above the yields of U.S. government securities or securities of investment grade issuers because they are subject to greater risks than these securities. These risks, which reflect their speculative character, include the following:
| ● | greater volatility;
| ● | greater credit risk and risk of default;
| ● | 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.
In addition, the prices of these non-investment grade securities are more sensitive to negative developments, such as a decline in the issuer’s revenues or a general economic downturn, than are the prices of higher grade securities. Non-investment grade securities tend to be less liquid than investment grade securities. The market value of non-investment grade securities may be more volatile than the market value of investment grade 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 investment grade securities, which primarily reflect fluctuations in general levels of interest rates. Ratings are relative and subjective and 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. The Fund may purchase securities of companies that are experiencing significant financial or business difficulties, including companies involved in bankruptcy or other reorganization and liquidation proceedings. Although such investments may result in significant financial returns to the Fund, they involve a substantial degree of risk. The level of analytical sophistication, both financial and legal, necessary for successful investments in issuers experiencing significant business and financial difficulties is unusually high. There can be no assurance that the Fund will correctly evaluate the value of the assets collateralizing its investments or the prospects for a successful reorganization or similar action. In any reorganization or liquidation proceeding relating to a portfolio investment, the Fund may lose all or part of its investment or may be required to accept collateral with a value less than the amount of the Fund’s initial investment. As a part of its investments in non-investment grade securities, the Fund may invest in the securities of issuers in default. The Fund invests in securities of issuers in default only when the Investment Adviser believes that such issuers will honor their obligations and emerge from bankruptcy protection and that the value of such issuers’ securities will appreciate. By investing in the 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 these securities will not otherwise appreciate. In addition to using statistical rating agencies and other sources, the Investment Adviser will also perform its own analysis of issuers in seeking investments that it believes to be underrated (and thus higher yielding) in light of the financial condition of the issuer. Its analysis of issuers may include, among other things, current and anticipated cash flow and borrowing requirements, value of assets in relation to historical cost, strength of management, responsiveness to business conditions, credit standing and current anticipated results of operations. In selecting investments for the Fund, the Investment Adviser may also consider general business conditions, anticipated changes in interest rates and the outlook for specific industries. Subsequent to its purchase by the Fund, an issue of securities may cease to be rated or its rating may be reduced. In addition, it is possible that statistical rating agencies might change their ratings of a particular issue to reflect subsequent events on a timely basis. Moreover, such ratings do not assess the risk of a decline in market value. None of these events will require the sale of the securities by the Fund, although the Investment Adviser will consider these events in determining whether the Fund should continue to hold the securities. Fixed income securities, including non-investment grade securities and comparable unrated securities, frequently have call or buy-back features that permit their issuers to call or repurchase the securities from their holders, such as the Fund. If an issuer exercises these rights during periods of declining interest rates, the Fund may have to replace the security with a lower yielding security, thus resulting in a decreased return for the Fund. The market for non-investment grade and comparable unrated securities has at various times, particularly during times of economic recession, experienced substantial reductions in market value and liquidity. Past recessions have adversely affected the ability of certain issuers of such securities to repay principal and pay interest thereon. The market for those securities could react in a similar fashion in the event of any future economic recession. U.S. Government Securities and Credit Rating Downgrade Risk. The Fund may invest in direct obligations of the government of the United States or its agencies. Obligations issued or guaranteed by the U.S. government, its agencies, authorities and instrumentalities and backed by the full faith and credit of the U.S. guarantee only that principal and interest will be timely paid to holders of the securities. These entities do not guarantee that the value of such obligations will increase, and, in fact, the market values of such obligations may fluctuate. In addition, not all U.S. government securities are backed by the full faith and credit of the United States; some are the obligation solely of the entity through which they are issued. There is no guarantee that the U.S. government would provide financial support to its agencies and instrumentalities if not required to do so by law. In 2011, S&P lowered its long term sovereign credit rating on the U.S. to “AA+” from “AAA.” The downgrade by S&P increased volatility in both stock and bond markets, resulting in higher interest rates and higher Treasury yields, and increased the costs of all kinds of debt. On August 1, 2023, Fitch Ratings lowered its long-term sovereign credit rating on the U.S. to “AA+” from “AAA.” This and any further downgrades of U.S. credit ratings could have significant adverse effects on the U.S. economy generally and could result in significant adverse impacts on issuers of securities held by the Fund itself. The Investment Adviser cannot predict the effects of similar events in the future on the U.S. economy and securities markets or on the Fund’s portfolio. The Investment Adviser monitors developments and seeks to manage the Fund’s portfolio in a manner consistent with achieving the Fund’s investment objectives, but there can be no assurance that it will be successful in doing so and the Investment Adviser may not timely anticipate or manage existing, new or additional risks, contingencies or developments. Value Investing Risk. The Fund focuses its investments on the securities of companies 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. Selection Risk. Different types of stocks tend to shift into and out of favor with stock market investors, depending on market and economic conditions. The performance of funds that invest in value-style stocks may at times be better or worse than the performance of stock funds that focus on other types of stocks or that have a broader investment style. Small and Mid-Cap Stock Risk. The Fund may invest in the equity securities of small-cap and/or mid-cap companies. Small and mid-cap companies offer investment opportunities and additional risks. They may not be well known to the investing public, may not be significantly owned by institutional investors and may not have steady earnings growth. These companies may have limited product or business lines and markets, as well as shorter operating histories, less experienced management and more limited financial resources than larger companies. Changes in any one line of business, therefore, may have a greater impact on a small or mid-cap company’s stock price than is the case for a larger company. In addition, the securities of such companies may be more vulnerable to adverse general market or economic developments, more volatile in price, have wider spreads between their bid and ask prices and have significantly lower trading volumes than the securities of larger capitalization companies. As such, securities of these small and mid-cap companies may be less liquid than those of larger companies, and may experience greater price fluctuations than larger companies. In addition, small-cap or mid-cap company securities may not be widely followed by investors, which may result in reduced demand. As a result, the purchase or sale of more than a limited number of shares of the securities of a small or mid-cap company may affect its market price. The Investment Adviser may need a considerable amount of time to purchase or sell its positions in these securities, particularly when other Investment Adviser-managed accounts or other investors are also seeking to purchase or sell them. The securities of small and mid-cap companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than larger capitalization securities or the market as a whole. In addition, small and mid-cap securities may be particularly sensitive to changes in interest rates, borrowing costs and earnings. Investing in small and mid-cap securities requires a longer-term view. Small and mid-cap companies, due to the size and kinds of markets that they serve, may be less susceptible than large-cap companies to intervention from the U.S. federal government by means of price controls, regulations or litigation. Foreign Securities Risk. 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 located in the United States. Foreign companies are not generally subject to uniform accounting, auditing and financial standards and requirements comparable to those applicable to U.S. 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. In addition, 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 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 available information about a foreign company than a U.S. company, and foreign companies may not be subject to accounting, auditing, and financial reporting standards and requirements comparable to or as uniform as those of U.S. companies. Foreign securities markets may have substantially less volume than U.S. securities markets and some foreign company securities are less liquid and their prices more volatile than securities of otherwise comparable U.S. 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, as there is generally less government supervision and regulation of exchanges, brokers, and issuers than there is in the U.S. The Fund might have greater difficulty taking appropriate legal action in non-U.S. courts and there may be less developed bankruptcy laws. 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-U.S. securities markets and the increased costs of maintaining the custody of foreign securities. Investments in foreign securities will expose the Fund to the direct or indirect consequences of political, social or economic changes in the countries that issue the securities or in which the issuers are located. Certain countries in which the Fund may invest have historically experienced, and may continue to experience, high rates of inflation, high interest rates, exchange rate fluctuations, large amounts of external debt, balance of payments and trade difficulties and extreme poverty and unemployment. Many of these countries are also characterized by political uncertainty and instability. The cost of servicing external debt will generally be adversely affected by rising international interest rates because many external debt obligations bear interest at rates which are adjusted based upon international interest rates. The Fund also may purchase ADRs or U.S. dollar-denominated securities of foreign issuers. ADRs are receipts issued by U.S. banks or trust companies in respect of securities of foreign issuers held on deposit for use in the U.S. 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 shareholder communications to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited securities. The following provides more detail on certain pronounced risks with foreign investing:
| ● | Foreign Currency Risk. The Fund may invest in companies whose securities are denominated or quoted in currencies other than U.S. dollars or have significant operations or markets outside of the United States. In such instances, the Fund will be exposed to currency risk, including the risk of fluctuations in the exchange rate between U.S. dollars (in which the Fund’s shares are denominated) and such foreign currencies, the risk of currency devaluations and the risks of non-exchangeability and blockage. As non-U.S. securities may be purchased with and payable in currencies of countries other than the U.S. dollar, the value of these assets measured in U.S. dollars may be affected favorably or unfavorably by changes in currency rates and exchange control regulations. Fluctuations in currency rates may adversely affect the ability of the Investment Adviser to acquire such securities at advantageous prices and may also adversely affect the performance of such assets.
Certain non-U.S. currencies, primarily in developing countries, have been devalued in the past and might face devaluation in the future. Currency devaluations generally have a significant and adverse impact on the devaluing country’s economy in the short and intermediate term and on the financial condition and results of companies’ operations in that country. Currency devaluations may also be accompanied by significant declines in the values and liquidity of equity and debt securities of affected governmental and private sector entities generally. To the extent that affected companies have obligations denominated in currencies other than the devalued currency, those companies may also have difficulty in meeting those obligations under such circumstances, which in turn could have an adverse effect upon the value of the Fund’s investments in such companies. There can be no assurance that current or future developments with respect to foreign currency devaluations will not impair the Fund’s investment flexibility, its ability to achieve its investment objective or the value of certain of its foreign currency-denominated investments.
| ● | Tax Consequences of Foreign Investing. The Fund’s transactions in foreign currencies, foreign currency-denominated debt obligations and certain foreign currency options, futures contracts and forward contracts (and similar instruments) may give rise to ordinary income or loss to the extent such income or loss results from fluctuations in the value of the foreign currency concerned. This treatment could increase or decrease the Fund’s ordinary income distributions to you, and may cause some or all of the Fund’s previously distributed income to be classified as a return of capital. In certain cases, the Fund may make an election to treat gain or loss attributable to certain investments as capital gain or loss.
| ● | EMU and Redenomination Risk. As the European debt crisis progressed, the possibility of one or more Eurozone countries exiting the European Monetary Union (“EMU”), or even the collapse of the euro as a common currency, arose, creating significant volatility at times in currency and financial markets generally. The effects of the collapse of the euro, or of the exit of one or more countries from the EMU, on the U.S. and global economies and securities markets are impossible to predict and any such events could have a significant adverse impact on the value and risk profile of the Fund’s portfolio. Any partial or complete dissolution of the EMU could have significant adverse effects on currency and financial markets, and on the values of the Fund’s portfolio investments. If one or more EMU countries were to stop using the euro as its primary currency, the Fund’s investments in such countries may be redenominated into a different or newly adopted currency. As a result, the value of those investments could decline significantly and unpredictably. In addition, securities or other investments that are redenominated may be subject to foreign currency risk, liquidity risk and valuation risk to a greater extent than similar investments currently denominated in euros. To the extent a currency used for redenomination purposes is not specified in respect of certain EMU-related investments, or should the euro cease to be used entirely, the currency in which such investments are denominated may be unclear, making such investments particularly difficult to value or dispose of. The Fund may incur additional expenses to the extent it is required to seek judicial or other clarification of the denomination or value of such securities.
| ● | Eurozone Risk. A number of countries in the EU have experienced, and may continue to experience, severe economic and financial difficulties, increasing the risk of investing in the European markets. In particular, many EU nations are susceptible to economic risks associated with high levels of debt, notably due to investments in sovereign debt of countries such as Greece, Italy, Spain, Portugal, and Ireland. As a result, financial markets in the EU have been subject to increased volatility and declines in asset values and liquidity. Responses to these financial problems by European governments, central banks, and others, including austerity measures and reforms, may not work, may result in social unrest, and may limit future growth and economic recovery or have other unintended consequences. Further defaults or restructurings by governments and others of their debt could have additional adverse effects on economies, financial markets, and asset valuations around the world. Greece, Ireland, and Portugal have already received one or more “bailouts” from other Eurozone member states, and it is unclear how much additional funding they will require or if additional Eurozone member states will require bailouts in the future. One or more other countries may also abandon the euro and/or withdraw from the EU, placing
its currency and banking system in jeopardy. The impact of these actions, especially if they occur in a disorderly fashion, is not clear, but could be significant and far-reaching.
| ● | Brexit Risk. On January 31, 2020, the United Kingdom officially withdrew from the EU, commonly referred to as “Brexit.” Following a transition period, the United Kingdom and the EU signed a Trade and Cooperation Agreement (“UK/EU Trade Agreement”), which came into full force on May 1, 2021 and set out the foundation of the economic and legal framework for trade between the United Kingdom and the EU. As the UK/EU Trade Agreement is a new legal framework, the implementation of the UK/EU Trade Agreement may result in uncertainty in its application and periods of volatility in both the United Kingdom and wider European markets. The United Kingdom’s exit from the EU is expected to result in additional trade costs and disruptions in this trading relationship. Furthermore, there is the possibility that either party may impose tariffs on trade in the future in the event that regulatory standards between the EU and the UK diverge. The terms of the future relationship may cause continued uncertainty in the global financial markets, and adversely affect our ability, and the ability of our portfolio companies, to execute our respective strategies and to receive attractive returns.
In particular, currency volatility may mean that our returns and the returns of our portfolio companies will be adversely affected by market movements and may make it more difficult, or more expensive, for us to implement appropriate currency hedging. Potential declines in the value of the British Pound and/or the euro against other currencies, along with the potential downgrading of the United Kingdom’s sovereign credit rating, may also have an impact on the performance of any of our portfolio companies located in the United Kingdom or Europe. In addition, certain European countries have experienced negative interest rates on certain fixed-income instruments. A negative interest rate policy is an unconventional central bank monetary policy tool where nominal target interest rates are set with a negative value (i.e., below zero percent) intended to help create self-sustaining growth in the local economy. Negative interest rates may result in heightened market volatility and may detract from the Fund’s performance to the extent the Fund is exposed to such interest rates. Among other things, these developments adversely affected the value and exchange rate of the euro and pound sterling, and any similar developments may continue to significantly affect the economies of all EU countries, which in turn may have a material adverse effect on the Fund’s investments in such countries, other countries that depend on EU countries for significant amounts of trade or investment, or issuers with exposure to debt issued by certain EU countries. To the extent the Fund has exposure to European markets or to transactions tied to the value of the euro, these events could negatively affect the value and liquidity of the Fund’s investments. All of these developments may continue to significantly affect the economies of all EU countries, which in turn may have a material adverse effect on the Fund’s investments in such countries, other countries that depend on EU countries for significant amounts of trade or investment, or issuers with exposure to debt issued by certain EU countries.
| ● | Russia. As a result of Russia’s military invasion of Ukraine in February 2022, the United States and other countries imposed broad-reaching political and economic sanctions on Russia, certain Russian allies believed to be providing them military or financial support, on private and public companies domiciled in Russia, including public issuers and banking and financial institutions, and on a variety of individuals.
These sanctions, combined with equivalent measures taken by foreign businesses ceasing operations in Russia, continue to adversely impact global financial markets, disrupt global supply chains, and impair the value and liquidity of issuers and funds that continue to maintain exposure to Russia and its allies, Russian investments, and sectors that can be impacted by restrictions on Russian imports and exports, such as the oil and gas industry. It is not possible to predict the duration or extent of longer-term consequences of this conflict, which could include further sanctions, retaliatory measures taken by Russia, embargoes, regional instability, geopolitical shifts and adverse effects on macroeconomic conditions, security conditions, currency exchange rates, and financial markets around the globe. Any of the foregoing consequences, including those we cannot yet predict, may negatively impact the Fund’s performance and the value of an investment in the Fund, even if the Fund does not have direct exposure to Russian issuers or issuers in other countries impacted by the invasion. In general terms, the overall negative impact to the Fund will depend on the extent to which the Fund is prohibited from selling or otherwise transacting in their investments at any given time and whether a fair market valuation can be readily obtained, particularly for any Russian currency-denominated investments and investments in US dollar-denominated American Depositary Receipts representing securities of Russian issuers. Restricted and Illiquid Securities. Unregistered securities are securities that cannot be sold publicly in the United States without registration under the Securities Act. An illiquid investment is a security or other investment that cannot be disposed of within seven days in the ordinary course of business at approximately the value at which the Fund has valued the investment. Unregistered securities often can be resold only in privately negotiated transactions with a limited number of purchasers or in a public offering registered under the Securities Act. Considerable delay could be encountered in either event and, unless otherwise contractually provided for, the Fund’s proceeds upon sale may be reduced by the costs of registration or underwriting discounts. The difficulties and delays associated with such transactions could result in the Fund’s inability to realize a favorable price upon disposition of unregistered securities, and at times might make disposition of such securities impossible. The Fund may be unable to sell illiquid investments when it desires to do so, resulting in the Fund obtaining a lower price or being required to retain the investment. Illiquid investments generally must be valued at fair value, which is inherently less precise than utilizing market values for liquid investments, and may lead to differences between the price at which a security is valued for determining the Fund’s net asset value and the price the Fund actually receives upon sale. Short Sales Risk. Short-selling involves selling securities which may or may not be owned and borrowing the same securities for delivery to the purchaser, with an obligation to replace the borrowed securities at a later date. If the price of the security sold short increases between the time of the short sale and the time the Fund replaces the borrowed security, the Fund will incur a loss; conversely, if the price declines, the Fund will realize a capital gain. Any gain will be decreased, and any loss will be increased, by the transaction costs incurred by the Fund, including the costs associated with providing collateral to the broker-dealer (usually cash and liquid securities). Although the Fund’s gain is limited to the price at which it sold the security short, its potential loss is theoretically unlimited. Short-selling necessarily involves certain additional risks. However, if the short seller does not own the securities sold short (an uncovered short sale), the borrowed securities must be replaced by securities purchased at market prices in order to close out the short position, and any appreciation in the price of the borrowed securities would result in a loss. Uncovered short sales expose the Fund to the risk of uncapped losses until a position can be closed out due to the lack of an upper limit on the price to which a security may rise. Purchasing securities to close out the short position can itself cause the price of the securities to rise further, thereby exacerbating the loss. There is the risk that the securities borrowed by the Fund in connection with a short-sale must be returned to the securities lender on short notice. If a request for return of borrowed securities occurs at a time when other short-sellers of the security are receiving similar requests, a “short squeeze” can occur, and the Fund may be compelled to replace borrowed securities previously sold short with purchases on the open market at the most disadvantageous time, possibly at prices significantly in excess of the proceeds received at the time the securities were originally sold short. In September 2008, in response to spreading turmoil in the financial markets, the SEC temporarily banned short selling in the stocks of numerous financial services companies, and also promulgated new disclosure requirements with respect to short positions held by investment managers. The SEC’s temporary ban on short selling of such stocks has since expired, but should similar restrictions and/or additional disclosure requirements be promulgated, especially if market turmoil occurs, the Fund may be forced to cover short positions more quickly than otherwise intended and may suffer losses as a result. Such restrictions may also adversely affect the ability of the Fund to execute its investment strategies generally. Similar emergency orders were also instituted in non-U.S. markets in response to increased volatility. The Fund’s ability to engage in short sales is also restricted by various regulatory requirements relating to short sales. Leverage Risk. The Fund currently uses financial leverage for investment purposes by issuing preferred shares. As of December 31, 2023, the amount of leverage represented approximately 30% of the Fund’s net assets. The Fund’s leveraged capital structure creates special risks not associated with unleveraged funds that have a similar investment objective and policies. These include the possibility of greater loss and the likelihood of higher volatility of the net asset value of the Fund and the asset coverage for any preferred shares or debt outstanding. Such volatility may increase the likelihood of the Fund having to sell investments in order to meet its obligations to make distributions on the preferred shares or principal or interest payments on debt securities, or to redeem preferred shares or repay debt when it may be disadvantageous to do so. The Fund’s use of leverage may require it to sell portfolio investments at inopportune times in order to raise cash to redeem preferred shares or otherwise de-leverage so as to maintain required asset coverage amounts or comply with the mandatory redemption terms of any outstanding preferred shares. The use of leverage magnifies both the favorable and unfavorable effects of price movements in the investments made by the Fund. To the extent the Fund is leveraged in its investment operations, the Fund will be subject to substantial risk of loss. The Fund cannot assure that borrowings or the issuance of notes or preferred shares will result in a higher yield or return to the holders of the common shares. Also, to the extent the Fund utilizes leverage, a decline in net asset value could affect the ability of the Fund to make common share distributions and such a failure to make distributions could result in the Fund ceasing to qualify as a RIC under the Code. For more information regarding the risks of a leverage capital structure to holders of the Fund’s common shares, see “Risk Factors and Special Considerations — Special Risks to Holder of Common Shares — Leverage Risk.” Special Risks Related to Investment in Derivatives. The Fund may participate in certain derivative transactions, as described herein. Such transactions entail certain execution, market, liquidity, counterparty, correlation, volatility, hedging and tax risks. Participation in derivatives 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 or other referenced instruments or markets is inaccurate, the consequences to the Fund may leave the Fund in a worse position than if it had not used such strategies. Risks inherent in the use of derivatives transactions include:
| ● | dependence on the Investment Adviser’s ability to predict correctly movements in the direction of the relevant measure;
| ● | imperfect correlation between the price of the derivative instrument and movements in the prices of the referenced assets;
| ● | 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 or instrument at a time that otherwise would be favorable for it to do so, or the possible need for the Fund to sell a security or instrument at a disadvantageous time due to a need for the Fund to remain in compliance with the 1940 Act restrictions regarding derivatives transactions; and
| ● | the creditworthiness of counterparties.
Certain derivatives 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 derivatives are traded may impose limits on the positions that the Fund may take in certain circumstances. 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 net asset value and may materially adversely affect the Fund in situations in which the Fund is required to sell derivative instruments. 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. Future CFTC or SEC rulemakings could potentially further limit or completely restrict the Fund’s ability to use these instruments as a part of the Fund’s investment strategy, increase the costs of using these instruments or make them less effective. Limits or restrictions applicable to the counterparties with which the Fund engages in derivative transactions could also prevent the Fund from using these instruments or affect the pricing or other factors relating to these instruments or may change the availability of certain investments. New regulation may make derivatives more costly, may limit the availability of derivatives, or may otherwise adversely affect the value or performance of derivatives. 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. The counterparty risk for cleared derivatives is generally lower than for uncleared OTC derivative transactions since generally a clearing organization becomes substituted for each counterparty to a cleared derivative contract and, in effect, guarantees the parties’ performance under the contract as each party to a trade looks only to the clearing organization for performance of financial obligations under the derivative contract. However, there can be no assurance that a clearing organization, or its members, will satisfy its obligations to the Fund, or that the Fund would be able to recover the full amount of assets deposited on its behalf with the clearing organization in the event of the default by the clearing organization or the Fund’s clearing broker. In addition, cleared derivative transactions benefit from daily marking-to-market and settlement, and segregation and minimum capital requirements applicable to intermediaries. Uncleared OTC derivative transactions generally do not benefit from such protections. This exposes the Fund to the risk that a counterparty will not settle a transaction in accordance with its terms and conditions because of a dispute over the terms of the contract (whether or not bona fide) or because of a credit or liquidity problem, thus causing the Fund to suffer a loss. Such “counterparty risk” is accentuated for contracts with longer maturities where events may intervene to prevent settlement, or where the Fund has concentrated its transactions with a single or small group of counterparties. Failure of Futures Commission Merchants and Clearing Organizations Risk. The Fund may deposit funds required to margin open positions in the derivative instruments subject to the CEA with a clearing broker registered as a “futures commission merchant” (“FCM”). The CEA requires an FCM to segregate all funds received from customers with respect to any orders for the purchase or sale of U.S. domestic futures contracts and cleared swaps from the FCM’s proprietary assets. Similarly, the CEA requires each FCM to hold in a separate secure account all funds received from customers with respect to any orders for the purchase or sale of foreign futures contracts and segregate any such funds from the funds received with respect to domestic futures contracts. However, all funds and other property received by a clearing broker from its customers are held by the clearing broker on a commingled basis in an omnibus account and may be invested by the clearing broker in certain instruments permitted under the applicable regulation. There is a risk that assets deposited by the Fund with any swaps or futures clearing broker as margin for futures contracts may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing broker. In addition, the assets of the Fund may not be fully protected in the event of the clearing broker’s bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing broker’s combined domestic customer accounts. Similarly, the CEA requires a clearing organization approved by the CFTC as a derivatives clearing organization to segregate all funds and other property received from a clearing member’s clients in connection with domestic futures, swaps and options contracts from any funds held at the clearing organization to support the clearing member’s proprietary trading. Nevertheless, with respect to futures contracts and options on futures, a clearing organization may use assets of a non-defaulting customer held in an omnibus account at the clearing organization to satisfy losses in that account resulting from the default by another customer on its payment obligations that leads to the clearing member’s default to the clearing organization. As a result, in the situation of a double default by a customer of the Fund’s clearing member and the clearing member itself with respect to payment obligations on the customer’s futures or options on futures, there is a risk that the Fund’s assets in an omnibus account with the clearing organization may be used to satisfy losses from the double default and that the Fund may not recover the full amount of any such assets. Swaps Risk. Swap agreements are two-party contracts entered into primarily by institutional investors for periods ranging from a few weeks to more than one year. In a standard “swap” transaction, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on particular predetermined investments or instruments. The gross returns to be exchanged or “swapped” between the parties are calculated with respect to a “notional amount,” i.e., the return on or increase in value of a particular dollar amount invested at a particular interest rate, in a particular foreign currency, or in a “basket” of securities representing a particular index. The “notional amount” of the swap agreement is only a fictive basis on which to calculate the obligations that the parties to a swap agreement have agreed to exchange. Historically, swap transactions have been individually negotiated non-standardized transactions entered into in the OTC markets and have not been subject to the same type of government regulation as exchange-traded instruments. However, in the U.S., the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”) has made broad changes to the derivatives market, granted significant new authority to the CFTC and the SEC to regulate derivatives (swaps and security-based swaps) and participants in these markets. The Dodd-Frank Act is intended to regulate the derivatives market by requiring many derivative transactions to be cleared and traded on an exchange, expanding entity registration requirements, imposing business conduct requirements on dealers and requiring banks to move some derivatives trading units to a non-guaranteed affiliate separate from the deposit-taking bank or divest them altogether. See “Risk Factors and Special Considerations—General Risks – Derivatives Regulation Risk.” Swap agreements will tend to shift the Fund’s investment exposure from one type of investment to another. For example, if the Fund agreed to pay fixed rates in exchange for floating rates while holding fixed-rate bonds, the swap would tend to decrease the Fund’s exposure to long-term interest rates. Caps and floors have an effect similar to buying or writing options. Depending on how they are used, swap agreements may increase or decrease the overall volatility of the Fund’s investments and its share price and yield. The most significant factor in the performance of swap agreements is the change in the specific interest rate, currency, or other factors that determine the amounts of payments due to and from the Fund. If a swap agreement calls for payments by the Fund, the Fund must be prepared to make such payments when due. The Fund may enter into swap agreements that would calculate the obligations of the parties to the agreements on a “net” basis. Consequently, the Fund’s obligations (or rights) under a swap agreement will generally be equal only to the net amount to be paid or received under the agreement based on the relative values of the positions held by each party to the agreement (the “net amount”). The Fund’s use of swap agreements may not be successful in furthering its investment objective, as the Investment Adviser may not accurately predict whether certain types of investments are likely to produce greater returns than other investments. Moreover, 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. The Fund may be able to eliminate its exposure under a swap agreement either by assignment or other disposition, or by entering into an offsetting swap agreement with the same party or a similarly creditworthy party. Forward Foreign Currency Exchange Contracts. The Fund may enter into forward foreign currency exchange contracts to protect the value of its portfolio against uncertainty in the level of future currency exchange rates between a particular foreign currency and the U.S. dollar or between foreign currencies in which its securities are or may be denominated. The Fund may enter into such contracts on a spot (i.e., cash) basis at the rate then prevailing in the currency exchange market or on a forward basis, by entering into a forward contract to purchase or sell currency. A forward contract on foreign currency is an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days agreed upon by the parties from the date of the contract at a price set on the date of the contract. Forward currency contracts (i) are traded in a market conducted directly between currency traders (typically, commercial banks or other financial institutions) and their customers, (ii) generally have no deposit requirements and (iii) are typically consummated without payment of any commissions. The Fund, however, may enter into forward currency contracts requiring deposits or involving the payment of commissions. The dealings of the Fund in forward foreign exchange are limited to hedging involving either specific transactions or portfolio positions. Transaction hedging is the purchase or sale of one forward foreign currency for another currency with respect to specific receivables or payables of the Fund accruing in connection with the purchase and sale of its portfolio securities or its payment of distributions. Position hedging is the purchase or sale of one forward foreign currency for another currency with respect to portfolio security positions denominated or quoted in the foreign currency to offset the effect of an anticipated substantial appreciation or depreciation, respectively, in the value of the currency relative to the U.S. dollar. In this situation, the Fund also may, for example, enter into a forward contract to sell or purchase a different foreign currency for a fixed U.S. dollar amount where it is believed that the U.S. dollar value of the currency to be sold or bought pursuant to the forward contract will fall or rise, as the case may be, whenever there is a decline or increase, respectively, in the U.S. dollar value of the currency in which its portfolio securities are denominated (this practice being referred to as a “cross-hedge”). In hedging a specific transaction, the Fund may enter into a forward contract with respect to either the currency in which the transaction is denominated or another currency deemed appropriate by the Investment Adviser. The amount the Fund may invest in forward currency contracts is limited to the amount of its aggregate investments in foreign currencies. The use of forward currency contracts may involve certain risks, including the failure of the counterparty to perform its obligations under the contract, and such use 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. The Fund will only enter into forward currency contracts with parties which the Investment Adviser believes to be creditworthy institutions. Futures Contracts and Options on Futures. 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 on price fluctuations; imperfect correlation between the contracts and the securities being hedged; and losses from investing in futures transactions that are potentially unlimited. Options Risk. To the extent that the Fund purchases options pursuant to a hedging strategy, the Fund will be subject to the following additional risks. If a put or call option purchased by the Fund is not sold when it has remaining value, and if the market price of the underlying security remains equal to or greater than the exercise price (in the case of a put), or remains less than or equal to the exercise price (in the case of a call), the Fund will lose its entire investment in the option. Where a put or call option on a particular security is purchased to hedge against price movements in that or a related security, the price of the put or call option may move more or less than the price of the security. If restrictions on exercise are imposed, the Fund may be unable to exercise an option it has purchased. If the Fund is unable to close out an option that it has purchased on a security, it will have to exercise the option in order to realize any profit or the option may expire worthless. Derivatives Regulation Risk. The Dodd-Frank Act has made broad changes to the derivatives market, granted significant new authority to the CFTC and the SEC to regulate derivatives (swaps and security-based swaps) and participants in these markets. The Dodd-Frank Act is intended to regulate the derivatives market by requiring many derivative transactions to be cleared and traded on an exchange, expanding entity registration requirements, imposing business conduct requirements on dealers and requiring banks to move some derivatives trading units to a non-guaranteed affiliate separate from the deposit-taking bank or divest them altogether. The CFTC has implemented mandatory clearing and exchange-trading of certain derivatives contracts including many standardized interest rate swaps and credit default index swaps. The CFTC continues to approve contracts for central clearing. Exchange-trading and central clearing are expected to reduce counterparty credit risk by substituting the clearinghouse as the counterparty to a swap and increase liquidity, but exchange-trading and central clearing do not make swap transactions risk-free. Uncleared swaps, such as non-deliverable foreign currency forwards, are subject to certain margin requirements that mandate the posting and collection of minimum margin amounts. This requirement may result in the Fund and its counterparties posting higher margin amounts for uncleared swaps than would otherwise be the case. Certain rules require centralized reporting of detailed information about many types of cleared and uncleared swaps. Reporting of swap data may result in greater market transparency, but may subject the Fund to additional administrative burdens, and the safeguards established to protect trader anonymity may not function as expected. Market Discount Risk. Whether investors will realize gains or losses upon the sale of additional securities of the Fund will depend upon the market price of the securities at the time of sale, which may be less or more than the Fund’s net asset value per share or the liquidation value of any Fund preferred shares issued. Since the market price of any additional securities the Fund may issue will be affected by such factors as the Fund’s dividend and distribution levels (which are in turn affected by expenses), dividend and distribution stability, net asset value, market liquidity, the relative demand for and supply of such securities in the market, general market and economic conditions and other factors beyond the control of the Fund, we cannot predict whether any such securities will trade at, below or above net asset value or at, below or above their public offering price or at, below or above their liquidation value, as applicable. For example, common shares of closed-end funds often trade at a discount to their net asset values and the Fund’s common shares may trade at such a discount. This risk may be greater for investors expecting to sell their securities of the Fund soon after the completion of a public offering for such securities. The risk of a market price discount from net asset value is separate and in addition to the risk that net asset value itself may decline. The Fund’s securities are designed primarily for long-term investors, and investors in the shares should not view the Fund as a vehicle for trading purposes. Long Term Objective; Not a Complete Investment Program. The Fund is intended for investors seeking a consistent level of after-tax total return consisting of income (with a current emphasis on qualifying dividends) and long-term capital gain. The Fund is not meant to provide a vehicle for those who wish to play short-term swings in the stock market. An investment in shares of the Fund should not be considered a complete investment program. Each shareholder should take into account the Fund’s investment objective as well as the shareholder’s other investments when considering an investment in the Fund. Management Risk. The Fund is subject to management risk because it is an actively managed portfolio. The Investment Adviser will apply 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. Decision-Making Authority Risk. Investors have no authority to make decisions or to exercise business discretion on behalf of the Fund, except as set forth in the Fund’s governing documents. The authority for all such decisions is generally delegated to the Board, who in turn, has delegated the day-to-day management of the Fund’s investment activities to the Investment Adviser, subject to oversight by the Board. 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. Market Disruption and Geopolitical Risk. General economic and market conditions, such as interest rates, availability of credit, inflation rates, economic uncertainty, supply chain disruptions, labor shortages, energy and other resource shortages, changes in laws, trade barriers, currency exchange controls and national and international political circumstances (including governmental responses to public health crises or the spread of infectious diseases), may have long-term negative effects on the U.S. and worldwide financial markets and economy. 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 Company, 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. Risks resulting from any future debt or other economic crisis could also have a detrimental impact on the global economy, the financial condition of financial institutions and the Fund’s 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, the Fund 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 objectives. The occurrence of events similar to those in recent years, such as localized wars, instability, new and ongoing pandemics, epidemics or outbreaks of infectious diseases in certain parts of the world, and catastrophic events such as fires, floods, earthquakes, tornadoes, hurricanes and global health epidemics, terrorist attacks in the U.S. and around the world, social and political discord, debt crises sovereign debt downgrades, increasingly strained relations between the U.S. 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 EU or the EMU, 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 U.S. and worldwide. In particular, the consequences of the Russian military invasion of Ukraine, the impact on inflation and increased disruption to supply chains and energy resources may impact the Fund’s 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 net asset values. In response to the conflict between Russia and Ukraine, the U.S. and other countries have imposed sanctions or other restrictive actions against Russia, Russian-backed separatist regions in Ukraine, and certain banks, companies, government officials and other individuals in Russia and Belarus. Any of the above factors, including sanctions, export controls, tariffs, trade wars and other governmental actions, could have a material adverse effect on the Fund. The Fund has no way to predict the duration or outcome of the situation, as the conflict and government reactions are rapidly developing and beyond the Fund’s control. Prolonged unrest, military activities, or broad-based sanctions could have a material adverse effect on companies in which the Fund invests. Such consequences also may increase such companies’ funding costs or limit their access to the capital markets. The current political climate has intensified concerns about a potential trade war between China and the U.S., as each country has 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 the Fund’s 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 the Fund. 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. Economic Events and Market Risk. Periods of market volatility remain, and 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 objectives. Regulation and Government Intervention Risk. Changes enacted by the current presidential administration could significantly impact the regulation of financial markets in the U.S. Areas subject to potential change, amendment or repeal include trade and foreign policy, corporate tax rates, energy and infrastructure policies, the environment and sustainability, criminal and social justice initiatives, immigration, healthcare and the oversight of certain federal financial regulatory agencies and the Federal Reserve. Certain of these changes can, and have, been effectuated through executive order. For example, the current administration has taken steps to rejoin the Paris climate accord of 2015 and incentivize certain clean energy technologies, cancel the Keystone XL pipeline, provide military support to Ukraine and change immigration enforcement priorities. Other potential changes that could be pursued by the current presidential administration could include an increase in the corporate income tax rate; changes to regulatory enforcement priorities; and spending on clean energy and infrastructure. It is not possible to predict which, if any, of these actions will be taken or, if taken, their effect on the economy, securities markets or the financial stability of the U.S. 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 the Fund’s ability to achieve its investment objectives. Additional risks arising from the differences in expressed policy preferences among the various constituencies in the branches of the U.S. government has led in the past, and may lead in the future, to short-term or prolonged policy impasses, which could, and has, resulted in shutdowns of the U.S. federal government. U.S. federal government shutdowns, especially prolonged shutdowns, could have a significant adverse impact on the economy in general and could impair the ability of issuers to raise capital in the securities markets. Any of these effects could have a material adverse effect on the Fund’s net asset value. In addition, the rules dealing with the U.S. federal income taxation are constantly under review by persons involved in the legislative process and by the IRS and the U.S. Treasury Department. The Tax Cuts and Jobs Act made substantial changes to the Code. Among those changes were a significant permanent reduction in the generally applicable corporate tax rate, changes in the taxation of individuals and other non-corporate taxpayers that generally but not universally reduce their taxes on a temporary basis subject to “sunset” provisions, the elimination or modification of various previously allowed deductions (including substantial limitations on the deductibility of interest and, in the case of individuals, the deduction for personal state and local taxes), certain additional limitations on the deduction of net operating losses, certain preferential rates of taxation on certain dividends and certain business income derived by non-corporate taxpayers in comparison to other ordinary income recognized by such taxpayers, and significant changes to the international tax rules. In addition, the Biden administration signed into law the Inflation Reduction Act, which modifies key aspects of the Code, including by creating an alternative minimum tax on certain corporations and an excise tax on stock repurchases by certain corporations. The effect of these and other changes is uncertain, both in terms of the direct effect on the taxation of an investment in the Fund’s shares and their indirect effect on the value of the Fund’s assets, Fund shares or market conditions generally. In addition, the U.S. government has proposed and adopted multiple regulations that could have a long-lasting impact on the Fund and on the closed-end fund industry in general. The SEC’s final rules and amendments that modernize reporting and disclosure, along with other potential upcoming regulations, could, among other things, restrict the Fund’s ability to engage in transactions, and/or increase overall expenses of the Fund. 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. 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’s investments may pay interest at floating rates based on LIBOR or may be subject to interest caps or floors based on LIBOR. The Fund may also obtain financing at floating rates based on LIBOR. Derivative instruments utilized by the Fund may also reference LIBOR. In July 2017, the head of the United Kingdom Financial Conduct Authority announced the desire to phase out the use of LIBOR by the end of 2021. LIBOR can no longer be used to calculate new deals as of December 31, 2021. Since December 31, 2021, all sterling, euro, Swiss franc and Japanese yen LIBOR settings and the 1-week and 2-month U.S. dollar LIBOR settings have ceased to be published or are no longer representative. Overnight and 12-month US dollar LIBOR settings permanently ceased as of June 30, 2023. 1-, 3-, and 6-month U.S. dollar LIBOR settings will continue to be published using a synthetic methodology until September 2024. Various financial industry groups have begun planning for the transition away from LIBOR, but there are challenges to converting certain securities and transactions to a new reference rate. Neither the effect of the LIBOR transition process nor its ultimate success can yet be known. As an alternative to LIBOR, the Financial Reporting Council, in conjunction with the Alternative Reference Rates Committee, a steering committee comprised of large U.S. financial institutions recommended replacing U.S. dollar LIBOR with the Secured Overnight Financing Rate (“SOFR”), a new index calculated by reference to short-term repurchase agreements, backed by Treasury securities. Abandonment of, or modifications to, LIBOR could have adverse impacts on newly issued financial instruments and any of our existing financial instruments which reference LIBOR. Given the inherent differences between LIBOR and SOFR, or any other alternative benchmark rate that may be established, there are many uncertainties regarding a transition from LIBOR, including, but not limited to, the need to amend all contracts with LIBOR as the referenced rate and how this will impact the cost of variable rate debt and certain derivative financial instruments. In addition, SOFR or other replacement rates may fail to gain market acceptance. Any failure of SOFR or alternative reference rates to gain market acceptance could adversely affect the return on, value of and market for securities linked to such rates. Neither the effect of the LIBOR transition process nor its ultimate success can yet be known. The transition process might lead to increased volatility and illiquidity in markets for, and reduce the effectiveness of, new hedges placed against, instruments whose terms currently include LIBOR. While some existing LIBOR-based instruments may contemplate a scenario where LIBOR is no longer available by providing for an alternative rate-setting methodology, there may be significant uncertainty regarding the effectiveness of any such alternative methodologies to replicate LIBOR. Not all existing LIBOR-based instruments may have alternative rate-setting provisions and there remains uncertainty regarding the willingness and ability of issuers to add alternative rate-setting provisions in certain existing instruments. Moreover, these alternative rate-setting provisions may not be designed for regular use in an environment where LIBOR ceases to be published, and may be an ineffective fallback following the discontinuation of LIBOR. On March 15, 2022, President Biden signed into law the Consolidated Appropriations Act of 2022, which among other things, provides for the use of interest rates based on SOFR in certain contracts currently based on LIBOR and a safe harbor from liability for utilizing SOFR-based interest rates as a replacement for LIBOR. The elimination of LIBOR could have an adverse impact on the market value of and/or transferability of any LIBOR-linked securities, loans, and other financial obligations or extensions of credit held by or due to us or on our overall financial condition or results of operations. 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. Legislation Risk. At any time after the date of this Annual 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 are becoming increasingly common and more sophisticated, and may be perpetrated by computer hackers, cyber-terrorists or others engaged in corporate espionage. 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 net asset value; 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 have been a number of recent highly publicized cases of companies reporting the unauthorized disclosure of client or customer information, as well as cyberattacks involving the dissemination, theft and destruction of corporate information or other assets, as a result of failure to follow procedures by employees or contractors or as a result of actions by third parties, including actions by terrorist organizations and hostile foreign governments. Although service providers typically have policies and procedures, business continuity plans and/or risk management systems intended to identify and mitigate cyber incidents, there are inherent limitations in such plans and systems including the possibility that certain risks have not been identified. Furthermore, the Fund cannot control the cyber security policies, plans and systems put in place by its service providers or any other third parties whose operations may affect the Fund or its shareholders. 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. Because technology is consistently changing, new ways to carry out cyber attacks are always developing. Therefore, there is a chance that some risks have not been identified or prepared for, or that an attack may not be detected, which puts limitations on the Fund’s ability to plan for or respond to a cyber attack. In addition to deliberate cyber attacks, unintentional cyber incidents can occur, such as the inadvertent release of confidential information by the Fund or its service providers. Like other funds and business enterprises, the Fund and its service providers are subject to the risk of cyber incidents occurring from time to time. 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. 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 collateralized in accordance with applicable regulatory requirements. 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 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. Legal, Tax and Regulatory Risk. Legal, tax and regulatory changes could occur that may have material adverse effects on the Fund or its shareholders. For example, the regulatory and tax environment for derivative instruments in which the Fund may participate is evolving, and such changes in the regulation or taxation of derivative instruments may have material adverse effects on the value of derivative instruments held by the Fund and the ability of the Fund to pursue its investment strategies. Similarly, the Biden administration has indicated that it intends to modify key aspects of the Code, including by increasing corporate and individual tax rates. Changes to the U.S. federal tax laws and interpretations thereof could adversely affect an investment in the Fund. We cannot assure you what percentage of the distributions paid on the Fund’s shares, if any, will consist of tax-advantaged qualified dividend income or long-term capital gains or what the tax rates on various types of income will be in future years. To qualify for the favorable U.S. federal income tax treatment generally accorded to RICs under the Code, the Fund must, among other things, meet certain asset diversification tests, derive in each taxable year at least 90% of its gross income from certain prescribed sources and distribute for each taxable year at least 90% of its “investment company taxable income.” Statutory limitations on distributions on the common shares if the Fund fails to satisfy the 1940 Act’s asset coverage requirements could jeopardize the Fund’s ability to meet such distribution requirements. While the Fund presently intends to purchase or redeem notes or preferred shares, if any, to the extent necessary in order to maintain compliance with such asset coverage requirements, there can be no assurance that such actions can be effected in time to meet the Code requirements. If for any taxable year the Fund does not qualify as a RIC, all of its taxable income for that year (including its net capital gain) would be subject to tax at regular corporate rates without any deduction for distributions to shareholders, and such distributions would be taxable as ordinary dividends to the extent of the Fund’s current and accumulated earnings and profits. The resulting corporate taxes would materially reduce the Fund’s net assets and the amount of cash available for distribution to shareholders. For a more complete discussion of these and other U.S. federal income tax considerations. Investment Dilution Risk. The Fund’s investors do not have preemptive rights to any shares the Fund may issue in the future. The Fund’s Agreement and Declaration of Trust authorizes it to issue an unlimited number of shares. The Board may make certain amendments to the Agreement and Declaration of Trust. After an investor purchases shares, the Fund may sell additional shares or other classes of shares in the future or issue equity interests in private offerings. To the extent the Fund issues additional equity interests after an investor purchases its shares, such investor’s percentage ownership interest in the Fund will be diluted. Anti-Takeover Provisions. The Agreement and Declaration of Trust and By-Laws of the Fund 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. See also – “Delaware Statutory Trust Act – Control Share Acquisitions.” Special Risks to Holders of Notes An investment in our notes is subject to special risks. Our notes are not likely to be listed on an exchange or automated quotation system. We cannot assure you that any market will exist for our notes or if a market does exist, whether it will provide holders with liquidity. Broker-dealers that maintain a secondary trading market for the notes are not required to maintain this market, and the Fund is not required to redeem notes if an attempted secondary market sale fails because of a lack of buyers. To the extent that our notes trade, they may trade at a price either higher or lower than their principal amount depending on interest rates, the rating (if any) on such notes and other factors. Special Risks to Holders of Fixed Rate Preferred Shares Illiquidity Prior to Exchange Listing. Prior to an offering, there will be no public market for any series of fixed rate preferred shares. In the event any additional series of fixed rate preferred shares are issued, we expect to apply to list such shares on a national securities exchange, which will likely be the NYSE. However, during an initial period, which is not expected to exceed 30 days after the date of initial issuance, such shares may not be listed on any securities exchange. During such period, the underwriters may make a market in such shares, though they will have no obligation to do so. Consequently, an investment in such shares may be illiquid during such period. Market Price Fluctuation. Fixed rate preferred shares may trade at a premium to or discount from liquidation value for various reasons, including changes in interest rates, perceived credit quality and other factors. Special Risks to Holders of Notes and Preferred Shares Common Share Repurchases. Repurchases of common shares by the Fund may reduce the net asset coverage of the notes and preferred shares, which could adversely affect their liquidity or market prices. Common Share 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 expects that it would return capital as part of its distribution. This would decrease the asset coverage per share with respect to the Fund’s notes or preferred shares, which could adversely affect their liquidity or market prices. During the fiscal year ended December 31, 2023, the Fund made distributions of $1.20 per common share, or which $0.97 per common share comprised return of capital. The composition of each distribution is estimated based on earnings as of the record date for the distribution. The actual composition of each distribution may change based on the Fund’s investment activity through the end of the calendar year. Credit Quality Ratings. The Fund may obtain credit quality ratings for its preferred shares or notes, if desired; however, it is not required to do so and may issue preferred shares or notes without any rating. If rated, the Fund does not impose any minimum rating necessary to issue such preferred shares or notes. The Fund’s portfolio must satisfy over-collateralization tests established by the relevant rating agencies in order to obtain and maintain attractive credit quality ratings for preferred shares or borrowings, if desired. 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. 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 notes or preferred shares, a rating by a ratings agency does not eliminate or necessarily mitigate the risks of investing in our preferred shares or notes, 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 notes or preferred shares, which may make such securities less liquid in the secondary market. If a rating agency downgrades the rating assigned to our preferred shares or notes, we may alter our portfolio or redeem all or a portion of the preferred shares or notes that are then redeemable under certain circumstances. Special Risks of Notes to Holders of Preferred Shares As provided in the 1940 Act, and subject to compliance with the Fund’s investment limitations, the Fund may issue notes. In the event the Fund were to issue such securities, the Fund’s obligations to pay dividends or make distributions and, upon liquidation of the Fund, liquidation payments in respect of its preferred shares would be subordinate to the Fund’s obligations to make any principal and interest payments due and owing with respect to its outstanding notes. Accordingly, the Fund’s issuance of notes would have the effect of creating special risks for the Fund’s preferred shareholders that would not be present in a capital structure that did not include such securities. Special Risks to Holders of Common Shares Dilution Risk. If the Fund determines to conduct a rights offering to subscribe for common shares, holders of common shares may experience dilution or accretion of the aggregate net asset value of their common shares. Such dilution or accretion will depend upon whether (i) such shareholders participate in the rights offering and (ii) the Fund’s net asset value per common share is above or below the subscription price on the expiration date of the rights offering. Shareholders who do not exercise their subscription rights may, at the completion of such an offering, own a smaller proportional interest in the Fund than if they exercised their subscription rights. As a result of such an offering, a shareholder may experience dilution in net asset value per share if the subscription price per share is below the net asset value per share on the expiration date. If the subscription price per share is below the net asset value per share of the Fund’s shares on the expiration date, a shareholder will experience an immediate dilution of the aggregate net asset value of such shareholder’s shares if the shareholder does not participate in such an offering and the shareholder will experience a reduction in the net asset value per share of such shareholder’s shares whether or not the shareholder participates in such an offering. The Fund cannot state precisely the extent of this dilution (if any) if the shareholder does not exercise such shareholder’s subscription rights because the Fund does not know what the net asset value per share will be when the offer expires or what proportion of the subscription rights will be exercised. Leverage Risk. The Fund currently uses financial leverage for investment purposes by issuing preferred shares and is also permitted to use other types of financial leverage, such as through the issuance of debt securities or additional preferred shares and borrowing from financial institutions. As provided in the 1940 Act and subject to certain exceptions, the Fund may issue additional senior securities (which may be stock, such as preferred shares, and/or securities representing debt) only if immediately after such issuance the value of the Fund’s total assets, less certain ordinary course liabilities, exceeds 300% of the amount of the debt outstanding and exceeds 200% of the amount of preferred shares and debt outstanding. As of December 31, 2023, the amount of leverage represented approximately 30% of the Fund’s net assets. The Fund’s leveraged capital structure creates special risks not associated with unleveraged funds having a similar investment objective and policies. These include the possibility of greater loss and the likelihood of higher volatility of the net asset value of the Fund and the asset coverage for the preferred shares. Such volatility may increase the likelihood of the Fund having to sell investments in order to meet its obligations to make distributions on the preferred shares or principal or interest payments on debt securities, or to redeem preferred shares or repay debt, when it may be disadvantageous to do so. The Fund’s use of leverage may require it to sell portfolio investments at inopportune times in order to raise cash to redeem preferred shares or otherwise de- leverage so as to maintain required asset coverage amounts or comply with the mandatory redemption terms of any outstanding preferred shares. The use of leverage magnifies both the favorable and unfavorable effects of price movements in the investments made by the Fund. To the extent that the Fund employs leverage in its investment operations, the Fund is subject to substantial risk of loss. The Fund cannot assure you that borrowings or the issuance of notes or preferred shares will result in a higher yield or return to the holders of the common shares. Also, since the Fund utilizes leverage, a decline in net asset value could affect the ability of the Fund to make common share distributions and such a failure to make distributions could result in the Fund ceasing to qualify as a RIC under the Code. Any decline in the net asset value of the Fund’s investments would be borne entirely by the holders of common shares. Therefore, if the market value of the Fund’s portfolio declines, the leverage will result in a greater decrease in net asset value to the holders of common shares than if the Fund were not leveraged. This greater net asset value decrease will also tend to cause a greater decline in the market price for the common shares. The Fund might be in danger of failing to maintain the required asset coverage of its borrowings, notes or preferred shares or of losing its ratings on its notes or preferred shares or notes or, in an extreme case, the Fund’s current investment income might not be sufficient to meet the distribution or interest requirements on the borrowings, preferred shares or notes. In order to counteract such an event, the Fund might need to liquidate investments in order to fund a redemption or repayment of some or all of the borrowings, preferred shares or notes. Preferred Share and Note Risk. The issuance of preferred shares or notes causes the net asset value and market value of the common shares to become more volatile. If the dividend rate on the preferred shares or the interest rate on the notes approaches the net rate of return on the Fund’s investment portfolio, the benefit of leverage to the holders of the common shares would be reduced. If the dividend rate on the preferred shares or the interest rate on the notes plus the management fee rate exceeds the net rate of return on the Fund’s portfolio, the leverage will result in a lower rate of return to the holders of common shares than if the Fund had not issued preferred shares or notes. If the Fund has insufficient investment income and gains, all or a portion of the distributions to preferred shareholders or interest payments to note holders would come from the common shareholders’ capital. Such distributions and interest payments reduce the net assets attributable to common shareholders. The Prospectus Supplement relating to any sale of preferred shares will set forth dividend rate on such preferred shares. In addition, the Fund would pay (and the holders of common shares will bear) all costs and expenses relating to the issuance and ongoing maintenance of the preferred shares or notes, including the advisory fees on the incremental assets attributable to the preferred shares or notes. Holders of preferred shares and notes may have different interests than holders of common shares and may at times have disproportionate influence over the Fund’s affairs. As provided in the 1940 Act and subject to certain exceptions, the Fund may issue senior securities (which may be stock, such as preferred shares, and/or securities representing debt, such as notes) only if immediately after the issuance the value of the Fund’s total assets, less certain ordinary course liabilities, exceeds 300% of the amount of the debt outstanding (i.e., for every dollar of indebtedness outstanding, the Fund is required to have at least three dollars of assets) and exceeds 200% of the amount of preferred shares and debt outstanding (i.e., for every dollar in liquidation preference of preferred stock outstanding, the Fund is required to have two dollars of assets), which is referred to as the “asset coverage” required by the 1940 Act. In the event the Fund fails to maintain an asset coverage of 100% for any notes outstanding for certain periods of time, the 1940 Act requires that either an event of default be declared or that the holders of such notes have the right to elect a majority of the Fund’s Trustees until asset coverage recovers to 110%. In addition, holders of preferred shares, voting separately as a single class, have the right (subject to the rights of noteholders) to elect two members of the Board at all times and in the event dividends become two full years in arrears would have the right to elect a majority of the Trustees until such arrearage is completely eliminated. In addition, preferred shareholders 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. Further, interest on notes will be payable when due as described in a Prospectus Supplement and if the Fund does not pay interest when due, it will trigger an event of default and the Fund expects to be restricted from declaring dividends and making other distributions with respect to common shares and preferred shares. Upon the occurrence and continuance of an event of default, the holders of a majority in principal amount of a series of outstanding notes or the Trustee will be able to declare the principal amount of that series of notes immediately due and payable upon written notice to the Fund. The 1940 Act also generally restricts the Fund from declaring distributions on, or repurchasing, common or preferred shares unless notes have an asset coverage of 300% (200% in the case of declaring distributions on preferred shares). The Fund’s common shares are structurally subordinated as to income and residual value to any preferred shares or notes in the Fund’s capital structure, in terms of priority to income and payment in liquidation. Restrictions imposed on the declarations and payment of dividends or other distributions to the holders of the Fund’s common shares and preferred shares, both by the 1940 Act and by requirements imposed by rating agencies, might impair the Fund’s ability to maintain its qualification as a RIC for U.S. federal income tax purposes. While the Fund intends to redeem its preferred shares or notes to the extent necessary to enable the Fund to distribute its income as required to maintain its qualification as a RIC under the Code, there can be no assurance that such actions can be effected in time to meet the Code requirements.
| ● | Portfolio Guidelines of Rating Agencies for Preferred Shares and/or Credit Facility. In order to obtain and maintain attractive credit quality ratings for preferred shares or notes, the Fund must comply with investment quality, diversification and other guidelines established by the relevant rating agencies. 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 shares or notes is lowered or withdrawn by the relevant rating agency, the Fund may also be required to redeem all or part of its outstanding preferred shares or notes, and the common shares of the Fund will lose the potential benefits associated with a leveraged capital structure.
| ● | Impact on Common Shares. Assuming that leverage will (1) be equal in amount to approximately 30% of the Fund’s total net assets (the Fund’s amount of outstanding financial leverage at December 31, 2023), and (2) charge interest or involve dividend payments at a projected blended annual average leverage dividend or interest rate of 5.16%, then the total return generated by the Fund’s portfolio (net of estimated expenses) must exceed approximately 1.58% of the Fund’s total net assets in order to cover such interest or dividend payments and other expenses specifically related to leverage. Of course, 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 ta-ble is furnished in response to requirements of the SEC. It is designed to illustrate the effect of leverage on common share 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. The table further reflects leverage representing 30% of the Fund’s net assets (the Fund’s amount of outstanding financial leverage at December 31, 2023), the Fund’s current projected blended annual average leverage dividend or interest rate of 5.16% (the average dividend rate on the Fund’s outstanding financial leverage at December 31, 2023), a base management fee at an annual rate of 0.50% and estimated annual incremental expenses attributable to any outstanding preferred shares of approximately 0.04% of the Fund’s net assets attributable to common shares. 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.
Assumed Return on Portfolio (Net of Expenses) |  |  | (10 | )% |  |  | (5 | )% |  |  | 0 | % |  |  | 5 | % |  |  | 10 | %
Corresponding Return to Common Shareholder |  |  | (16.76 | )% |  |  | (9.61 | )% |  |  | (2.46 | )% |  |  | 4.70 | % |  |  | 11.85 | %
Common share 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 shares) 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.
| ● | Market Discount Risk. As described above in “—General Risks—Market Discount Risk,” common shares of closed-end funds often trade at a discount to their net asset values and the Fund’s common shares may trade at such a discount. This risk may be greater for investors expecting to sell their common shares of the Fund soon after completion of a public offering. The common shares of the Fund are designed primarily for long-term investors and investors in the shares should not view the Fund as a vehicle for trading purposes.
Special Risk to Holders of Subscription Rights There is a risk that changes in market conditions may result in the underlying common or preferred shares 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 common or preferred shares issued may be reduced, and the common or preferred shares may trade at less favorable prices than larger offerings for similar securities. |  |  |  |  |  |  |  |  |

Capital Stock [Table Text Block] |  |  |  |  |  |  |  |  |  | 7. Capital. The Fund is authorized to issue an unlimited number of common shares of beneficial interest (par value $0.001). The Board has authorized the repurchase of its shares on the open market when the shares are trading 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, 2023 and December 31, 2022, the Fund did not repurchase and retire any common shares in the open market. On May 12, 2022, the Fund distributed one transferable right for each of the 5,377,458 common shares outstanding on that date. Four rights were required to purchase one additional common share at the subscription price of $16 per share. On June 30, 2022, the Fund issued 591,453 common shares receiving net proceeds of $9,148,248 after the deduction of estimated offering expenses of $315,000. The NAV of the Fund decreased by $0.15 per share on the day the additional shares were issued due to the shares being issued below NAV. For the years ended December 31, 2023 and 2022, transactions in common stock were as follows:
|  | Year Ended December 31, 2023 |  |  | Year Ended December 31, 2022 |

The Fund’s Declaration of Trust, as amended, authorizes the issuance of an unlimited number of shares of $0.001 par value Preferred Shares. Preferred Shares are senior to the common shares and result in the financial leveraging of the common shares. Such leveraging tends to magnify both the risks and opportunities to common shareholders. Dividends on the Series A and Series B Preferred are cumulative and the liquidation value is $50 per share. The Fund is required by the 1940 Act and by the Fund’s Statement of Preferences to meet certain asset coverage tests with respect to the Preferred Shares. 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 A and Series B Preferred Shares at the redemption price of $50 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 shareholders 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 shareholders. As of December 31, 2023, the Fund had an effective shelf registration authorizing the issuance of $141 million in common or preferred shares, expiring August 13, 2024. The Series A Preferred has an annual dividend rate of 3.80%. The Fund may redeem at any time all or any part of the Series A Preferred at the liquidation value plus accumulated and unpaid dividends. During the years ended December 2023 and 2022, the Fund repurchased and retired, respectively, 738 and 11,442 of the Series A Preferred Shares in the open market at investments of $33,803 and $534,861 and at average discounts of approximately 8.41% and 6.53% from its liquidation preference. On December 11, 2023, the Board approved June 26, 2024 as an additional put date for the Series B Preferred. Each Series B Preferred shareholder has the right to put their shares to the Fund in each of the 60 day periods ending June 26, 2024 and December 26, 2024, after which the Series B preferred becomes perpetual. After proper notification is given, the Series B preferred shares are callable at the liquidation value of $50.00 per share plus accrued dividends. On December 28, 2021, the Fund redeemed and retired 51,968 shares of Series B Preferred where shareholders properly submitted for redemption during the 30 day period prior to December 26, 2021 at their liquidation value of $50 per share plus any accumulated and unpaid dividends. On January 8, 2022, the fund repurchased 1,048 shares of Series B Preferred at their liquidation preference of $50 per share. On December 26, 2023, the Fund redeemed and retired 460,602 shares of Series B preferred where shareholders properly submitted for redemption during the 60 day period ending on December 26, 2023 at their liquidation value of $50 per share plus any accumulated or unpaid dividends. The following table summarizes Cumulative Preferred Stock information:

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 Trustees and, under certain circumstances, are entitled to elect a majority of the Board of Trustees. 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. |  |  |  |  |  |  |  |  |

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 Trustees and, under certain circumstances, are entitled to elect a majority of the Board of Trustees. 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. |  |  |  |  |  |  |  |  |
Preferred Stock Restrictions, Other [Text Block] |  |  |  |  |  |  |  |  |  | The Fund’s Declaration of Trust, as amended, authorizes the issuance of an unlimited number of shares of $0.001 par value Preferred Shares. Preferred Shares are senior to the common shares and result in the financial leveraging of the common shares. Such leveraging tends to magnify both the risks and opportunities to common shareholders. Dividends on the Series A and Series B Preferred are cumulative and the liquidation value is $50 per share. The Fund is required by the 1940 Act and by the Fund’s Statement of Preferences to meet certain asset coverage tests with respect to the Preferred Shares. 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 A and Series B Preferred Shares at the redemption price of $50 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 shareholders 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 shareholders. As of December 31, 2023, the Fund had an effective shelf registration authorizing the issuance of $141 million in common or preferred shares, expiring August 13, 2024. The Series A Preferred has an annual dividend rate of 3.80%. The Fund may redeem at any time all or any part of the Series A Preferred at the liquidation value plus accumulated and unpaid dividends. During the years ended December 2023 and 2022, the Fund repurchased and retired, respectively, 738 and 11,442 of the Series A Preferred Shares in the open market at investments of $33,803 and $534,861 and at average discounts of approximately 8.41% and 6.53% from its liquidation preference. On December 11, 2023, the Board approved June 26, 2024 as an additional put date for the Series B Preferred. Each Series B Preferred shareholder has the right to put their shares to the Fund in each of the 60 day periods ending June 26, 2024 and December 26, 2024, after which the Series B preferred becomes perpetual. After proper notification is given, the Series B preferred shares are callable at the liquidation value of $50.00 per share plus accrued dividends. On December 28, 2021, the Fund redeemed and retired 51,968 shares of Series B Preferred where shareholders properly submitted for redemption during the 30 day period prior to December 26, 2021 at their liquidation value of $50 per share plus any accumulated and unpaid dividends. On January 8, 2022, the fund repurchased 1,048 shares of Series B Preferred at their liquidation preference of $50 per share. On December 26, 2023, the Fund redeemed and retired 460,602 shares of Series B preferred where shareholders properly submitted for redemption during the 60 day period ending on December 26, 2023 at their liquidation value of $50 per share plus any accumulated or unpaid dividends. |  |  |  |  |  |  |  |  |

Risk [Text Block] |  |  |  |  |  |  |  |  |  | Market Risk. The market price of securities owned by the Fund may go up or down, sometimes rapidly or unpredictably. Securities may decline in value due to factors affecting securities markets generally or particular industries represented in the securities markets. The value of a security may decline due to general market conditions which are not specifically related to a particular company, such as real or perceived adverse economic conditions, changes in the general outlook for corporate earnings, changes in interest or currency rates, adverse changes to credit markets or adverse investor sentiment generally. The value of a security may also decline due to factors which affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry. During a general downturn in the securities markets, multiple asset classes may decline in value simultaneously. Equity securities generally have greater price volatility than fixed income securities. Credit ratings downgrades may also negatively affect securities held by the Fund. Even when markets perform well, there is no assurance that the investments held by the Fund will increase in value along with the broader market. In addition, market risk includes the risk that geopolitical and other events will disrupt the economy on a national or global level. For instance, war, terrorism, market manipulation, government defaults, government shutdowns, political changes or diplomatic developments, public health emergencies (such as the spread of infectious diseases, pandemics and epidemics) and natural/environmental disasters can all negatively impact the securities markets, which could cause the Fund to lose value. These events could reduce consumer demand or economic output, result in market closures, travel restrictions or quarantines, and significantly adversely impact the economy. 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, has in the past resulted, and may in the future result, in a government shutdown, which could have an adverse impact on the Fund’s investments and operations. Additional and/or prolonged U.S. federal 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. Governmental and quasi-governmental authorities and regulators throughout the world have previously responded to serious economic disruptions with a variety of significant fiscal and monetary policy changes, including, but not limited to, direct capital infusions into companies, new monetary programs and dramatically lower interest rates. An unexpected or sudden reversal of these policies, or the ineffectiveness of these policies, could increase volatility in securities markets, which could adversely affect the Fund’s investments. Any market disruptions could also prevent the Fund from executing advantageous investment decisions in a timely manner. To the extent that the Fund focuses its investments in a region enduring geopolitical market disruption, it will face higher risks of loss, although the increasing interconnectivity between global economies and financial markets can lead to events or conditions in one country, region or financial market adversely impacting a different country, region or financial market. Thus, investors should closely monitor current market conditions to determine whether the Fund meets their individual financial needs and tolerance for risk. Current market conditions may pose heightened risks with respect to the Fund’s investment in fixed income securities. Central banks such as the Federal Reserve Bank have been increasing interest rates, though this trend has tempered recently as the rate of inflation slows. There is a risk that additional increases in interest rates or a prolonged period of rising interest rates may cause the economy to enter a recession. Any interest rate increases in the future could cause the value of the Fund to decrease. In addition, inflation levels have been at their highest point in nearly 40 years and the Federal Reserve has been engaged in a campaign to raise certain benchmark interest rates in an effort to combat inflation. As inflation increases, the real value of the Fund’s common stock and distributions therefore may decline. Exchanges and securities markets may close early, close late or issue trading halts on specific securities or generally, which may result in, among other things, the Fund being unable to buy or sell certain securities or financial instruments at an advantageous time or accurately price its portfolio investments. |  |  |  |  |  |  |  |  |
Interest Rate Risk Generally [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
General Description of Registrant [Abstract] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Risk [Text Block] |  |  |  |  |  |  |  |  |  | Interest Rate Risk Generally. The primary risk associated with dividend-and interest-paying securities is interest rate risk. A decrease in interest rates will generally result in an increase in the investment value of such securities, while increases in interest rates will generally result in a decline in the investment value of such securities. This effect is generally more pronounced for fixed rate securities than for securities whose income rate is periodically reset. General interest rate fluctuations may have a substantial negative impact on the Fund’s investments, the value of the Fund and the Fund’s rate of return. A reduction in the interest or dividend rates on new investments relative to interest or dividend rates on current investments could also have an adverse impact on the Fund’s net investment income. An increase in interest rates could decrease the value of any investments held by the Fund that earn fixed interest or dividend rates, including debt securities, convertible securities, preferred stocks, loans and high-yield bonds, and also could increase interest or dividend expenses, thereby decreasing net income. The magnitude of these fluctuations in the market price of bonds and other income- or dividend-paying 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 net asset value. The Fund may lose money if short-term or long-term interest rates rise sharply in a manner not anticipated by Fund management. To the extent the Fund invests in securities that may be prepaid at the option of the obligor, the sensitivity of such securities to changes in interest rates may increase (to the detriment of the Fund) when interest rates rise. Moreover, because rates on certain floating rate securities typically reset only periodically, changes in prevailing interest rates (and particularly sudden and significant changes) can be expected to cause some fluctuations in the net asset value of the Fund to the extent that it invests in floating rate securities. These basic principles of bond prices also apply to U.S. government securities. A security backed by the “full faith and credit” of the U.S. government is guaranteed only as to its stated interest rate and face value at maturity, not its current market price. Just like other income- or dividend-paying securities, government-guaranteed securities will fluctuate in value when interest rates change. The Fund’s use of leverage will tend to increase the Fund’s interest rate risk. The Fund may invest in variable and floating rate instruments, which generally are less sensitive to interest rate changes than longer duration fixed rate instruments but may decline in value in response to rising interest rates if, for example, the rates at which they pay interest do not rise as much, or as quickly, as market interest rates in general. Conversely, variable and floating rate instruments generally will not increase in value if interest rates decline. The Fund also may invest in inverse floating rate securities, which may decrease in value if interest rates increase, and which also may exhibit greater price volatility than fixed rate obligations with similar credit quality. To the extent the Fund holds variable or floating rate instruments, a decrease (or, in the case of inverse floating rate securities, an increase) in market interest rates will adversely affect the income received from such securities, which may adversely affect the net asset value of the Fund’s common shares. Central banks such as the Federal Reserve Bank have been increasing interest rates, though this trend has tempered recently as the rate of inflation slows. There is a risk that heightened interest rates may cause the economy to enter a recession. Any such recession would negatively impact the Fund and the investments held by the Fund. These impacts may include:
| ● | severe declines in the Fund’s net asset values;
| ● | inability of the Fund to accurately or reliably value its portfolio;
| ● | inability of the Fund to pay any dividends or distributions;
| ● | inability of the Fund to maintain its status as a registered investment company (“RIC”) under the Internal Revenue Code of 1986, as amended (the “Code”);
| ● | declines in the value of the Fund’s investments;
| ● | increased risk of default or bankruptcy by the companies in which the Fund invests;
| ● | increased risk of companies in which the Fund invests being unable to weather an extended cessation of normal economic activity and thereby impairing their ability to continue functioning as a going concern; and
| ● | limited availability of new investment opportunities.

Risk [Text Block] |  |  |  |  |  |  |  |  |  | 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. This risk may be elevated compared to historical market conditions because of recent monetary policy measures and the current interest rate environment. Inflation rates may change frequently and significantly as a result of various factors, including unexpected shifts in the domestic or global economy and changes in economic policies, and the Fund’s investments may not keep pace with inflation, which may result in losses to Fund shareholders. As inflation increases, the real value of the Fund’s shares and dividends may decline. In addition, during any periods of rising inflation, interest rates of any debt securities held by the Fund would likely increase, which would tend to further reduce returns to shareholders. This risk is greater for fixed-income instruments with longer maturities. |  |  |  |  |  |  |  |  |

Risk [Text Block] |  |  |  |  |  |  |  |  |  | Industry Risks. The Fund invests in foreign and domestic companies involved in the Utilities Industry and, as a result, the value of the common shares will be more susceptible to factors affecting those particular types of companies, including governmental regulation, inflation, cost increases in 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 product development, infrastructure and capital construction programs, including costs associated with compliance with environmental and other regulations. Sector Risk. The Fund concentrates its investments in the Utilities Industry. As a result, the Fund’s investments may be subject to greater risk and market fluctuation than a fund that had securities representing a broader range of investment alternatives. The prices of equity securities issued by certain types of utility companies may change more in response to interest rate changes than the equity securities of other companies. Generally, when interest rates go up, the value of securities issued by these companies goes down. Conversely, when interest rates go down, the value of securities issued by these companies goes up. There is no guarantee that this relationship will hold in the future. Privatization in the Utilities Industry may subject companies to greater competition and losses in profitability. Companies in the Utilities Industry may have difficulty obtaining an adequate return on invested capital, raising capital, or financing large construction programs during periods of inflation or unsettled capital markets. Government Regulation. Companies in certain sectors of the Utilities Industry (such as power generation and distribution) are subject to extensive governmental regulatory requirements. In the United States, most companies in the Utilities Industry are regulated by state and/or federal authorizes. For example, at the federal level in the United States, the Federal Energy Regulatory Commission (“FERC”), the Federal Trade Commission (“FTC”), the SEC and the Nuclear Regulatory Commission (“NRC”) have authority to oversee electric and combination electric and gas utilities. Certain of these regulations that are intended to limit the concentration of ownership and control of companies in these industries may prevent companies in which the Fund invests from making certain investments that they would otherwise make. Other regulations may cause Utilities Industry companies to incur substantial additional costs or lengthy delays in connection with the completion of capital investments or the introduction of new products or services to market. There are substantial differences between the regulatory practices and policies in various jurisdictions, and any given regulatory agency may make major shifts in policy from time to time. There is no assurance that regulatory authorities will, in the future, permit companies to implement rate increases or that such increases will be adequate to permit the payment of dividends on such issuer’s common stocks. Additionally, existing and possible future regulatory legislation may make it even more difficult for companies in the Utilities Industry to obtain adequate relief from rate regulation. Regulatory considerations limit the percentage of the shares of a public utility or utility holding company held by a fund or by an adviser and its affiliates on behalf of all their clients. In particular, approval of the FERC under the Federal Power Act would generally be required for (i) the Fund to acquire and hold 10% or more of the voting securities of any publicly traded public utility or utility holding company, and (ii) for the Fund together with any affiliated fund or other affiliated entity to acquire and hold in the aggregate 20% or more of the voting securities of any publicly traded public utility or utility holding company. Other requirements for FERC or state utility commission approval of the acquisition of voting securities may apply as well. Apart from approval requirements with respect to acquisitions of voting securities, the Fund may choose to limit its ownership of public utility or utility holding company voting securities in order to avoid the imposition of regulatory requirements under federal or state law such as those that attend status as a “holding company” under the Public Utility Holding Company Act of 2005. Similarly, various types of ownership restrictions are imposed by the Federal Communications Commission (“FCC”), on investment in media companies and cellular licensees. For example, the FCC’s broadcast and cable multiple-ownership and cross ownership rules, which apply to the radio, television, and cable industries, provide that investment advisers are deemed to have an “attributable” interest whenever the adviser has the right to determine how five percent or more of the issued and outstanding voting stock of a broadcast company or cable system operator may be voted. These rules limit the number of broadcast stations both locally and nationally that a single entity is permitted to own, operate, or control and prohibit ownership of certain competitive communications providers in the same location. The FCC also applies limited ownership restrictions on cellular licensees serving rural areas. An attributable interest in a cellular company arises from the right to control 20% or more of its voting stock. Attributable interests that may result from the role of the Investment Adviser and its principals in connection with other funds, managed accounts and companies may limit the Fund’s ability to invest in certain mass media and cellular companies. These limitations may unfavorably restrict the ability of the Fund to make certain investments. Deregulation. Changing regulation constitutes one of the key industry-specific risks for the Fund, especially with respect to its investments in traditionally regulated public utilities and partially regulated utility or telecommunications companies. Domestic and foreign regulators may monitor and control such companies’ revenues and costs, and therefore may limit utility profits and dividends paid to investors, which could result in reduced income to the Fund. Regulatory authorities also may restrict a company’s access to new markets, thereby diminishing the company’s long-term prospects. In some jurisdictions certain portions of various utilities functions have been deregulated. Deregulation may eliminate restrictions on profits and dividends of companies, but may also subject these companies to greater risks of loss. Thus, deregulation could have a positive or negative impact on the Fund. The Investment Adviser believes that certain Utilities Industry companies’ fundamentals should continue to improve as the industry undergoes deregulation. The nature of regulation of the Utilities Industry continues to evolve both in the United States and in foreign countries. In recent years, changes in regulation in the United States increasingly have allowed companies in the Utilities Industry to provide services and products outside their traditional geographic areas and lines of business, creating new areas of competition within these industries. In some instances, companies in the Utilities Industry are operating on an unregulated basis. However, a number of companies have failed in their efforts to take advantage of the deregulated environment and are seeking to refocus in their primary business. Nonetheless, because of trends toward deregulation and the evolution of independent producers as well as new entrants to the field of telecommunications, non-regulated providers of utility and telecommunications services have become a significant part of their respective industries. The emergence of competition and deregulation may result in certain companies in the Utilities Industry being able to earn more than their traditional regulated rates of return, while others may be forced to defend their core business from increased competition and may be less profitable. Reduced profitability, as well as new uses of funds (such as for expansion, operations or stock buybacks) could result in cuts in dividend payout rates. The Investment Adviser seeks to take advantage of favorable investment opportunities that may arise from these structural changes. Of course, there can be no assurance that favorable developments will occur in the future. Environmental and Other Regulatory Matters. Companies in the Utilities Industry in which the Fund will invest may be subject to a number of host country statutory and regulatory standards and required approvals relating to energy, labor and environmental laws. Certain permits and regulatory approvals may be required to be obtained for certain investments by companies in which the Fund will invest and failure by such companies to obtain such permits and regulatory approvals could adversely affect the Fund’s investment. Companies also face considerable costs associated with environmental compliance, nuclear waste clean-up and safety regulation. Increasingly, regulators are calling upon electric utilities to bear these added costs, and there is a risk that these costs will not be fully recovered through an increase in revenues. Changing weather patterns and natural disasters affect consumer demand for utility services (e.g., electricity, heat and air conditioning), which, in turn, affects utility revenues. The adoption by a host country of new laws, policies or regulations or changes in the interpretation or application of existing laws, policies and regulations that modify the present regulatory environment could also have an adverse effect on the Fund’s investments. Regulatory risk affects companies in the Utilities Industry in part because governments may be party to private Utilities Industry investments as lessors, customers, regulators or partners. Moreover, for political reasons, governments may control the prices at which companies in the Utilities Industry can sell their products, which can adversely affect the Fund’s investment in such a company. Under the laws of certain countries that are host to Utilities Industry companies in which the Fund may invest, such companies may be required to comply with a number of statutes and regulations during their operation pertaining to environmental controls or restrictions, and the storage, handling, transportation and disposal of hazardous and toxic material, waste or other substances. Compliance with such requirements may be costly and may materially affect the profitability of such companies. For example, governments have been increasing their attention to issues related to greenhouse gas (“GHG”) emissions and climate change, and regulatory measures to limit or reduce GHG emissions are currently in various stages of discussion or implementation. GHG emissions-related regulations could substantially harm energy companies, including by reducing the demand for energy fuels and increasing compliance costs. Failure by such a company to comply with any such statutes or regulations could have adverse effects on its business results and prospects, which could have negative consequences for investors such as the Fund. Foreign Utility Companies. Foreign companies in the Utilities Industry are also subject to regulation, although such regulation may or may not be comparable to regulation in the United States. Foreign companies in the Utilities Industry may be more heavily regulated by their respective governments than companies in the United States and, as in the United States, generally are required to seek government approval for rate increases. In addition, many foreign utilities use fuels that may cause more pollution than those used in the United States, which may require such utilities to invest in pollution control equipment to meet any proposed pollution restrictions. Foreign regulatory systems vary from country to country and may evolve in ways different from regulation in the United States. Additionally, because the effectiveness of the judicial systems in non-U.S. countries varies, the Fund or companies in which it may invest may have difficulty in successfully pursuing claims in the courts of such countries. Privatization, which refers to the trend toward investor ownership of assets rather than government ownership, is expected to occur in newer, faster-growing economies and in mature economies. Of course, there is no assurance that such favorable developments will occur or that investment opportunities in foreign markets will increase. The revenues of domestic and foreign utility companies generally reflect the economic growth and development in the geographic areas in which they do business. Financing. At certain times, including during inflationary periods, companies in the Utilities Industry encounter difficulties in obtaining financing for product development, infrastructure and construction programs. Issuers experiencing such difficulties may also experience lower profitability, which can result in reduced income to the Fund. Historically, companies in the Utilities Industry have also encountered such financing difficulties during inflationary periods, although we cannot assure you that such a relationship will continue and that companies in the Utilities Industry will not encounter financing difficulties during non-inflationary periods. Equipment and Supplies. Companies in the Utilities Industry may face the risk of lengthy delays and increased costs associated with the design, development, construction, licensing and operation of their facilities or sale of their products. Moreover, technological innovations may render existing plants, equipment or products obsolete. Increased costs and a reduction in the availability of fuel (such as oil, coal, nuclear or natural gas) also may adversely affect the profitability of utility companies. Electric utilities may be burdened by unexpected increases in fuel and other operating costs. They may also be negatively affected when long-term interest rates rise. Long-term borrowings are used to finance most utility investments, and rising interest rates lead to higher financing costs and reduced earnings. Investments in certain kinds of utility companies are also subject to certain additional risks. Electric. Certain of the issuers of securities held in the Fund’s portfolio may own or operate nuclear generating facilities. Governmental authorities may from time to time review existing policies and impose additional requirements governing the licensing, construction and operation of nuclear power plants. In the past, nuclear generating projects in the electric utility industry have experienced substantial cost increases, construction delays and licensing difficulties. These have been caused by various factors, including inflation, high financing costs, required design changes and rework, allegedly faulty construction, objections by groups and governmental officials, limits on the ability to obtain financing, reduced forecasts of energy requirements and economic conditions. This experience indicates that the risk of significant cost increases, delays and licensing difficulties remain present until completion and achievement of commercial operation of any nuclear project. Also, nuclear generating units in service have experienced unplanned outages or extensions of scheduled outages due to equipment problems or new regulatory requirements sometimes followed by a significant delay in obtaining regulatory approval to return to service. A major accident at a nuclear plant anywhere could cause the imposition of limits or prohibitions on the operation, construction or licensing of nuclear units. Prolonged changes in climatic conditions can also have a significant impact on both the revenues of an electric and gas utility as well as its expenses. The construction and operation of nuclear power facilities are subject to strict scrutiny by, and evolving regulations of, the Nuclear Regulatory Commission and state agencies which have comparable jurisdiction. Strict scrutiny might result in higher operating costs and higher capital expenditures, with the risk that the regulators may disallow inclusion of these costs in rate authorizations or the risk that a company may not be permitted to operate or complete construction of a facility. In addition, operators of nuclear power plants may be subject to significant costs for disposal of nuclear fuel and for decommissioning such plants. The rating agencies look closely at the business profile of utilities. Ratings for companies are expected to be affected to a greater extent in the future by how their asset base is utilized. Electric utility companies that focus more on the generation of electricity may be assigned less favorable ratings as this business is expected to be competitive and the least regulated. On the other hand, companies that focus on transmission and distribution, which is expected to be the least competitive and the more regulated part of the business, may see higher ratings given the greater predictability of cash flow. A number of states are considering or have enacted deregulation proposals. The introduction of competition into the industry as a result of such deregulation has at times resulted in lower revenue, lower credit ratings, increased default risk, and lower electric utility security prices. Such increased competition may also cause long-term contracts, which electric utilities previously entered into to buy power, to become “stranded assets” which have no economic value. Any loss associated with such contracts must be absorbed by ratepayers and investors. In addition, some electric utilities have acquired electric utilities overseas to diversify, enhance earnings and gain experience in operating in a deregulated environment. In some instances, such acquisitions have involved significant borrowings, which have burdened the acquirer’s balance sheet. There is no assurance that current deregulation proposals will be adopted. However, deregulation in any form could significantly impact the electric utilities industry. Following deregulation of the energy markets in certain states, a number of companies have engaged in energy trading and incurred substantial losses. Certain of these energy trading businesses have been accused of employing improper accounting practices and have been required to make significant restatements of their financial results. In addition, several energy companies have been accused of attempting to manipulate the price and availability of energy in certain states. Telecommunications. The telecommunications industry today includes both traditional telephone companies with a history of broad market coverage and highly regulated businesses and cable companies, which began as small, lightly regulated businesses focused on limited markets. Today these two historically different businesses are converging in an industry which is trending toward larger, competitive, national and international markets with an emphasis on deregulation. Companies that distribute telephone services and provide access to the telephone networks still comprise the greatest portion of this segment, but non-regulated activities such as cellular telephone services, paging, data processing, equipment retailing, computer software and hardware services are becoming increasingly significant components as well. The presence of unregulated companies in this industry and the entry of traditional telephone companies into unregulated or less regulated businesses provide significant investment opportunities with companies which may increase their earnings at faster rates than had been allowed in traditional regulated businesses. Still, increasing competition, technological innovations and other structural changes could adversely affect the profitability of such utilities and the growth rate of their dividends. Given mergers and proposed legislation and enforcement changes, it is likely that both traditional telephone companies and cable companies will continue to provide an expanding range of utility services to residential, corporate and governmental customers. Gas. Gas transmission companies and gas distribution companies are also undergoing significant changes. In the United States, interstate transmission companies are regulated by the FERC, which began reducing its regulation of the industry in the 1980’s. Many companies have diversified into oil and gas exploration and development, making returns more sensitive to energy prices. In the recent decade, gas utility companies have been adversely affected by disruptions in the oil industry, including related to political conditions in oil producing regions (such as the Middle East), by increased concentration and competition, and by differing approaches to energy policy in the United States, including increased incentives for the exploration and production of alternative energy and climate-related programs, revocation of federal permits for, and public opposition to, natural gas pipelines, such as the cross-border operation permit for the Keystone XL Pipeline and other policy decisions that favor alternative energy sources. The extension of these policies, or the adoption of similar policies, could adversely affect the financial performance of gas transmission and distribution companies. Prolonged changes in climatic conditions can also have a significant impact on both the revenues and expenses of a gas utility. Natural gas is the cleanest of the hydrocarbon fuels, and this may result in incremental shifts in fuel consumption toward natural gas and away from oil and coal, even for electricity generation. However, technological or regulatory changes within the industry may delay or prevent this result. Water. In the case of the water utility sector, the industry is highly fragmented, and most water supply companies find themselves in mature markets, although upgrading of fresh water and waste water systems is an expanding business. Technology and Competitive Risks. The introduction and phase-in of new technologies can affect a utility company’s competitive strength. The race by long-distance telephone providers to incorporate fiber optic technology is one example of competitive risk within the utilities industry. The increasing role of independent power producers (IPPs) in the natural gas and electric utility segments of the utilities industry is another example of competitive risk. Typically, IPPs wholesale power to established local providers, but there is a trend toward letting them sell power directly to industrial consumers. Co-generation facilities, such as those of landfill operators that produce methane gas as a byproduct of their core business, pose another competitive challenge to gas and electric utilities. In addition to offering a less expensive source of power, these companies may receive more favorable regulatory treatment than utilities seeking to expand facilities that consume nonrenewable energy sources. Utilities Industry Generally. There can be no assurance that the positive developments noted above, including those relating to privatization and changing regulation, will occur or that risk factors other than those noted above will not develop in the future. Moreover, price disparities within selected utility groups and discrepancies in relation to averages and indices have occurred frequently for reasons not directly related to the general movements or price trends of utility common stocks. Causes of these discrepancies include changes in the overall demand for and supply of various securities (including the potentially depressing effect of new stock offerings), and changes in investment objectives, market expectations or cash requirements of other purchasers and sellers of securities. Cyber and Physical Security Risks. Companies in the Utilities Industry have experienced sabotage to company infrastructure, property and equipment, attempts to breach company operating systems and other similar incidents in the past, which have resulted in shutdowns and/or disruptions in their operations. For example, in May 2021, a U.S. fuel pipeline operator was the target of a ransomware attack, which resulted in the shutdown of a massive oil pipeline system that supplies the eastern United States. Recently, in September 2022, several subsea explosions ruptured the Nord Stream I pipeline and one Nordstream II pipe, causing a substantial disruption in the delivery of natural gases under the Baltic Sea. Several counties continue to investigate the incident, but several, including Sweden, have concluded the explosions were caused by grievous sabotage. Companies in the Utilities Industry may continue to be subject to attempts to gain unauthorized access to or through their operating systems and physical attacks on industry and company infrastructure, property and equipment. Any physical damage, system failure, cybersecurity breach, ransomware attack, system disruption or other material harm could interrupt or delay operations and impact a company in the Utilities Industry’s ability to manage its operations and report financial performance, which could have a materially adverse effect on existing and future business. These and other developments may adversely impact the value of the Fund’s investments in companies in the Utilities Industry. Leveraged Capital Structures. It is expected that Utilities Industry companies in which the Fund will invest may employ considerable leverage, a significant portion of which may be at floating interest rates. As a result, a Utilities Industry company may be subject to increased exposure to adverse economic factors such as a significant rise in interest rates, a severe downturn in the economy or deterioration in the condition of such company or its industry. |  |  |  |  |  |  |  |  |

Risk [Text Block] |  |  |  |  |  |  |  |  |  | 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 net asset value of the Fund may at any point in time be less than the net asset value of the Fund at the time the shareholder invested in the Fund, even after taking into account any reinvestment of distributions. |  |  |  |  |  |  |  |  |
Common Stock Risk [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
General Description of Registrant [Abstract] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Risk [Text Block] |  |  |  |  |  |  |  |  |  | Common Stock Risk. Common stock of an issuer in the Fund’s portfolio may decline in price for a variety of reasons, including if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock in which the Fund invests is structurally subordinated as to income and residual value to preferred stock, bonds and other debt instruments in a company’s capital structure, in terms of priority to corporate income, and therefore will be subject to greater dividend risk than preferred stock or debt instruments of such issuers. In addition, while common stock has historically generated higher average returns than fixed income securities, common stock has also experienced significantly more volatility in those returns. |  |  |  |  |  |  |  |  |
Preferred Stock Risk [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
General Description of Registrant [Abstract] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Risk [Text Block] |  |  |  |  |  |  |  |  |  | Preferred Stock Risk. 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 shareholders. 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 se 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 U.S. federal income tax or securities laws. A redemption by the issuer may negatively impact the return of the security held by the Fund.
Convertible Securities Risk [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
General Description of Registrant [Abstract] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Risk [Text Block] |  |  |  |  |  |  |  |  |  | Convertible Securities Risk. Convertible securities generally offer lower interest or dividend yields than non-convertible securities of similar quality. The market values of convertible securities tend to decline as interest rates increase and, conversely, to increase as interest rates decline. In the absence of adequate anti-dilution provisions in a convertible security, dilution in the value of the Fund’s holding may occur in the event the underlying stock is subdivided, additional equity securities are issued for below market value, a stock dividend is declared or the issuer enters into another type of corporate transaction that has a similar effect. |  |  |  |  |  |  |  |  |
Merger Arbitrage Risk [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
General Description of Registrant [Abstract] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Risk [Text Block] |  |  |  |  |  |  |  |  |  | Merger Arbitrage Risk. The Fund may invest in securities of companies for which a tender or exchange offer has been made or announced, and in securities of companies for which a merger, consolidation, liquidation or reorganization proposal has been announced. The principal risk of such investments is that certain of such proposed transactions may be renegotiated, terminated or involve a longer time frame than originally contemplated, in which case the Fund may realize losses. Such risk is sometimes referred to as “merger arbitrage risk.” Among the factors that affect the level of risk with respect to the completion of the transaction are the deal spread and number of bidders, the friendliness of the buyer and seller, the strategic rationale behind the transaction, the existence of regulatory hurdles, the level of due diligence completed on the target company and the ability of the buyer to finance the transaction. If the spread between the purchase price and the current price of the seller’s stock is small, the risk that the transaction will not be completed may outweigh the potential return. If there is very little interest by other potential buyers in the target company, the risk of loss may be higher than where there are back-up buyers that would allow the arbitrageur to realize a similar return if the current deal falls through. Unfriendly management of the target company or change in friendly management in the middle of a deal increases the risk that the deal will not be completed even if the target company’s board has approved the transaction and may involve the risk of litigation expense if the target company pursues litigation in an attempt to prevent the deal from occurring. The underlying strategy behind the deal is also a risk consideration because the less a target company will benefit from a merger or acquisition, the greater the risk. There is also a risk that an acquiring company may back out of an announced deal if, in the process of completing its due diligence of the target company, it discovers something undesirable about such company. In addition, merger transactions are also subject to regulatory risk because a merger transaction often must be approved by a regulatory body or pass governmental antitrust review. All of these factors affect the timing and likelihood that the transaction will close. Even if the Investment Adviser selects announced deals with the goal of mitigating the risks that the transaction will fail to close, such risks may still delay the closing of such transaction to a date later than the Fund originally anticipated, reducing the level of desired return to the Fund. Merger arbitrage positions are also subject to the risk of overall market movements. To the extent that a general increase or decline in equity values affects the stocks involved in a merger arbitrage position differently, the position may be exposed to loss. Finally, merger arbitrage strategies depend for success on the overall volume of global merger activity, which has historically been cyclical in nature. During periods when merger activity is low, it may be difficult or impossible to identify opportunities for profit or to identify a sufficient number of such opportunities to provide balance among potential merger transactions. To the extent that the number of announced deals and corporate reorganizations decreases or the number of investors in such transactions increases, it is possible that merger arbitrage spreads will tighten, causing the profitability of investing in such transactions to diminish, which will in turn decrease the returns to the Fund from such investment activity. |  |  |  |  |  |  |  |  |
Recapitalization Risk [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
General Description of Registrant [Abstract] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Risk [Text Block] |  |  |  |  |  |  |  |  |  | Recapitalization Risk. In recapitalizations, a corporation may restructure its balance sheet by selling specific assets, significantly leveraging other assets and creating new classes of equity securities to be distributed, together with a substantial payment in cash or in debt securities, to existing shareholders. In connection with such transactions, there is a risk that the value of the cash and new securities distributed will not be as high as the cost of the Fund’s original investment or that no such distribution will ultimately be made and the value of the Fund’s investment will decline. To the extent an investment in a company that has undertaken a recapitalization is retained by the Fund, the Fund’s risks will generally be comparable to those associated with investments in highly leveraged companies, generally including higher than average sensitivity to (i) short-term interest rate fluctuations, (ii) downturns in the general economy or within a particular industry or (iii) adverse developments within the company itself. |  |  |  |  |  |  |  |  |
Distribution Riskfor Equity Income Securities [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
General Description of Registrant [Abstract] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Risk [Text Block] |  |  |  |  |  |  |  |  |  | Distribution Risk for Equity Income Securities. In selecting equity income securities in which the Fund will invest, the Investment Adviser will consider the issuer’s history of making regular periodic distributions (i.e., dividends) to its equity holders. An issuer’s history of paying dividends, however, does not guarantee that the issuer will continue to pay dividends in the future. The dividend income stream associated with equity income securities generally is not guaranteed and will be subordinate to payment obligations of the issuer on its debt and other liabilities. Accordingly, in the event the issuer does not realize sufficient income in a particular period both to service its liabilities and to pay dividends on its equity securities, it may forgo paying dividends on its equity securities. In addition, because in most instances issuers are not obligated to make periodic distributions to the holders of their equity securities, such distributions or dividends generally may be discontinued at the issuer’s discretion. Dividend-producing equity income securities, in particular those whose market price is closely related to their yield, may exhibit greater sensitivity to interest rate changes. See “—Fixed Income Securities Risks—Interest Rate Risk.” The Fund’s investments in dividend-producing equity income securities may also limit its potential for appreciation during a broad market advance. The prices of dividend-producing equity income securities can be highly volatile. Investors should not assume that the Fund’s investments in these securities will necessarily reduce the volatility of the Fund’s net asset value or provide “protection,” compared to other types of equity income securities, when markets perform poorly. |  |  |  |  |  |  |  |  |
Fixed Income Securities Risks [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
General Description of Registrant [Abstract] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Risk [Text Block] |  |  |  |  |  |  |  |  |  | Fixed Income Securities Risks. Fixed 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. See “— General Risks—Interest Rate Risks Generally.”
| ● | 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. To the extent the Fund invests in below investment grade securities, it will be exposed to a greater amount of credit risk than a fund which only invests in investment grade securities. See “—Non-Investment Grade Securities.” In addition, to the extent the Fund uses credit derivatives, such use will expose it to additional risk in the event that the bonds underlying the derivatives default. The degree of credit risk depends on the issuer’s financial condition and on the terms of the securities.
| ● | 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 reinvest in lower yielding securities, resulting in a possible decline in the Fund’s income and distributions to shareholders. This is known as prepayment or “call” risk. Below investment grade securities frequently have call features that allow the issuer to redeem the security at dates prior to its stated maturity at a specified price (typically greater than par) only if certain prescribed conditions are met (“call protection”).
For premium bonds (bonds acquired at prices that exceed their par or principal value) purchased by the Fund, prepayment risk may be enhanced.
| ● | 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 has no set policy regarding portfolio maturity or duration of the fixed-income securities it may hold. The Investment Adviser may seek to adjust the duration or maturity of the Fund’s fixed-income holdings based on its assessment of current and projected market conditions and all other factors that the Investment Adviser deems relevant. 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 net asset value that is expected for every percentage point change in interest rates. The two have an inverse relationship. Duration can be a useful tool to estimate anticipated price changes to a fixed pool of income securities associated with changes in interest rates. For example, a duration of five years means that a 1% decrease in interest rates will increase the net asset value of the portfolio by approximately 5%; if interest rates increase by 1%, the net asset value 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. Prices of securities with longer durations tend to be more sensitive to interest rate changes than securities with shorter durations. In general, a portfolio of securities with a longer duration can be expected to be more sensitive to interest rate changes than a portfolio with a shorter duration. Any decisions as to the targeted duration or maturity of any particular category of investments will be made based on all pertinent market factors at any given time. The Fund may incur costs in seeking to adjust the portfolio average duration or maturity. 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. |  |  |  |  |  |  |  |  |
Corporate Bonds Risk [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] |  |  |  |  |  |  |  |  |  | Corporate Bonds Risk. The market value of a corporate bond generally may be expected to rise and fall inversely with interest rates. The market value of intermediate and longer-term corporate bonds is generally more sensitive to changes in interest rates than is the market value of shorter term corporate bonds. The market value of a corporate bond also may be affected by factors directly related to the issuer, such as investors’ perceptions of the creditworthiness of the issuer, the issuer’s financial performance, perceptions of the issuer in the market place, performance of management of the issuer, the issuer’s capital structure and use of financial leverage and demand for the issuer’s goods and services. Certain risks associated with investments in corporate bonds are described elsewhere in this Annual Report in further detail, including under “— Fixed Income Securities Risks — Credit Risk,” “—Fixed Income Securities Risks—Interest Rate Risk” and “—Fixed Income Securities Risks—Prepayment Risk,” “—General Risks—Inflation Risk” and “—General Risks—Interest Rate Risk Generally.” There is a risk that the issuers of corporate bonds may not be able to meet their obligations on interest or principal payments at the time called for by an instrument. Corporate bonds of below investment grade quality are often high risk and have speculative characteristics and may be particularly susceptible to adverse issuer-specific developments. Corporate bonds of below investment grade quality are subject to the risks described herein under “—Non-Investment Grade Securities.” |  |  |  |  |  |  |  |  |
Non Investment Grade Securities [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
General Description of Registrant [Abstract] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Risk [Text Block] |  |  |  |  |  |  |  |  |  | Non-Investment Grade Securities. The Fund may invest in below investment-grade securities, also known as “high-yield” securities or “junk” bonds. Securities rated below investment grade, which may be preferred stock or debt, are predominantly speculative and involve major risk exposure to adverse conditions. Securities that are rated lower than “BBB” by S&P or lower than “Baa” by Moody’s (or unrated securities considered by the Investment Adviser to be of comparable quality) are referred to in the financial press as “junk bonds” or “high-yield” securities and generally pay a premium above the yields of U.S. government securities or securities of investment grade issuers because they are subject to greater risks than these securities. These risks, which reflect their speculative character, include the following:
| ● | greater volatility;
| ● | greater credit risk and risk of default;
| ● | 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.
In addition, the prices of these non-investment grade securities are more sensitive to negative developments, such as a decline in the issuer’s revenues or a general economic downturn, than are the prices of higher grade securities. Non-investment grade securities tend to be less liquid than investment grade securities. The market value of non-investment grade securities may be more volatile than the market value of investment grade 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 investment grade securities, which primarily reflect fluctuations in general levels of interest rates. Ratings are relative and subjective and 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. The Fund may purchase securities of companies that are experiencing significant financial or business difficulties, including companies involved in bankruptcy or other reorganization and liquidation proceedings. Although such investments may result in significant financial returns to the Fund, they involve a substantial degree of risk. The level of analytical sophistication, both financial and legal, necessary for successful investments in issuers experiencing significant business and financial difficulties is unusually high. There can be no assurance that the Fund will correctly evaluate the value of the assets collateralizing its investments or the prospects for a successful reorganization or similar action. In any reorganization or liquidation proceeding relating to a portfolio investment, the Fund may lose all or part of its investment or may be required to accept collateral with a value less than the amount of the Fund’s initial investment. As a part of its investments in non-investment grade securities, the Fund may invest in the securities of issuers in default. The Fund invests in securities of issuers in default only when the Investment Adviser believes that such issuers will honor their obligations and emerge from bankruptcy protection and that the value of such issuers’ securities will appreciate. By investing in the 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 these securities will not otherwise appreciate. In addition to using statistical rating agencies and other sources, the Investment Adviser will also perform its own analysis of issuers in seeking investments that it believes to be underrated (and thus higher yielding) in light of the financial condition of the issuer. Its analysis of issuers may include, among other things, current and anticipated cash flow and borrowing requirements, value of assets in relation to historical cost, strength of management, responsiveness to business conditions, credit standing and current anticipated results of operations. In selecting investments for the Fund, the Investment Adviser may also consider general business conditions, anticipated changes in interest rates and the outlook for specific industries. Subsequent to its purchase by the Fund, an issue of securities may cease to be rated or its rating may be reduced. In addition, it is possible that statistical rating agencies might change their ratings of a particular issue to reflect subsequent events on a timely basis. Moreover, such ratings do not assess the risk of a decline in market value. None of these events will require the sale of the securities by the Fund, although the Investment Adviser will consider these events in determining whether the Fund should continue to hold the securities. Fixed income securities, including non-investment grade securities and comparable unrated securities, frequently have call or buy-back features that permit their issuers to call or repurchase the securities from their holders, such as the Fund. If an issuer exercises these rights during periods of declining interest rates, the Fund may have to replace the security with a lower yielding security, thus resulting in a decreased return for the Fund. The market for non-investment grade and comparable unrated securities has at various times, particularly during times of economic recession, experienced substantial reductions in market value and liquidity. Past recessions have adversely affected the ability of certain issuers of such securities to repay principal and pay interest thereon. The market for those securities could react in a similar fashion in the event of any future economic recession. |  |  |  |  |  |  |  |  |
U S Government Securities And Credit Rating Downgrade Risk [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
General Description of Registrant [Abstract] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Risk [Text Block] |  |  |  |  |  |  |  |  |  | U.S. Government Securities and Credit Rating Downgrade Risk. The Fund may invest in direct obligations of the government of the United States or its agencies. Obligations issued or guaranteed by the U.S. government, its agencies, authorities and instrumentalities and backed by the full faith and credit of the U.S. guarantee only that principal and interest will be timely paid to holders of the securities. These entities do not guarantee that the value of such obligations will increase, and, in fact, the market values of such obligations may fluctuate. In addition, not all U.S. government securities are backed by the full faith and credit of the United States; some are the obligation solely of the entity through which they are issued. There is no guarantee that the U.S. government would provide financial support to its agencies and instrumentalities if not required to do so by law. In 2011, S&P lowered its long term sovereign credit rating on the U.S. to “AA+” from “AAA.” The downgrade by S&P increased volatility in both stock and bond markets, resulting in higher interest rates and higher Treasury yields, and increased the costs of all kinds of debt. On August 1, 2023, Fitch Ratings lowered its long-term sovereign credit rating on the U.S. to “AA+” from “AAA.” This and any further downgrades of U.S. credit ratings could have significant adverse effects on the U.S. economy generally and could result in significant adverse impacts on issuers of securities held by the Fund itself. The Investment Adviser cannot predict the effects of similar events in the future on the U.S. economy and securities markets or on the Fund’s portfolio. The Investment Adviser monitors developments and seeks to manage the Fund’s portfolio in a manner consistent with achieving the Fund’s investment objectives, but there can be no assurance that it will be successful in doing so and the Investment Adviser may not timely anticipate or manage existing, new or additional risks, contingencies or developments. |  |  |  |  |  |  |  |  |
Value Investing Risk [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] |  |  |  |  |  |  |  |  |  | Value Investing Risk. The Fund focuses its investments on the securities of companies 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. |  |  |  |  |  |  |  |  |

Risk [Text Block] |  |  |  |  |  |  |  |  |  | Selection Risk. Different types of stocks tend to shift into and out of favor with stock market investors, depending on market and economic conditions. The performance of funds that invest in value-style stocks may at times be better or worse than the performance of stock funds that focus on other types of stocks or that have a broader investment style. |  |  |  |  |  |  |  |  |
Small And Mid Cap Stock Risk [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] |  |  |  |  |  |  |  |  |  | Small and Mid-Cap Stock Risk. The Fund may invest in the equity securities of small-cap and/or mid-cap companies. Small and mid-cap companies offer investment opportunities and additional risks. They may not be well known to the investing public, may not be significantly owned by institutional investors and may not have steady earnings growth. These companies may have limited product or business lines and markets, as well as shorter operating histories, less experienced management and more limited financial resources than larger companies. Changes in any one line of business, therefore, may have a greater impact on a small or mid-cap company’s stock price than is the case for a larger company. In addition, the securities of such companies may be more vulnerable to adverse general market or economic developments, more volatile in price, have wider spreads between their bid and ask prices and have significantly lower trading volumes than the securities of larger capitalization companies. As such, securities of these small and mid-cap companies may be less liquid than those of larger companies, and may experience greater price fluctuations than larger companies. In addition, small-cap or mid-cap company securities may not be widely followed by investors, which may result in reduced demand. As a result, the purchase or sale of more than a limited number of shares of the securities of a small or mid-cap company may affect its market price. The Investment Adviser may need a considerable amount of time to purchase or sell its positions in these securities, particularly when other Investment Adviser-managed accounts or other investors are also seeking to purchase or sell them. The securities of small and mid-cap companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than larger capitalization securities or the market as a whole. In addition, small and mid-cap securities may be particularly sensitive to changes in interest rates, borrowing costs and earnings. Investing in small and mid-cap securities requires a longer-term view. Small and mid-cap companies, due to the size and kinds of markets that they serve, may be less susceptible than large-cap companies to intervention from the U.S. federal government by means of price controls, regulations or litigation. |  |  |  |  |  |  |  |  |
Foreign Securities Risk [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
General Description of Registrant [Abstract] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Risk [Text Block] |  |  |  |  |  |  |  |  |  | Foreign Securities Risk. 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 located in the United States. Foreign companies are not generally subject to uniform accounting, auditing and financial standards and requirements comparable to those applicable to U.S. 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. In addition, 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 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 available information about a foreign company than a U.S. company, and foreign companies may not be subject to accounting, auditing, and financial reporting standards and requirements comparable to or as uniform as those of U.S. companies. Foreign securities markets may have substantially less volume than U.S. securities markets and some foreign company securities are less liquid and their prices more volatile than securities of otherwise comparable U.S. 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, as there is generally less government supervision and regulation of exchanges, brokers, and issuers than there is in the U.S. The Fund might have greater difficulty taking appropriate legal action in non-U.S. courts and there may be less developed bankruptcy laws. 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-U.S. securities markets and the increased costs of maintaining the custody of foreign securities. Investments in foreign securities will expose the Fund to the direct or indirect consequences of political, social or economic changes in the countries that issue the securities or in which the issuers are located. Certain countries in which the Fund may invest have historically experienced, and may continue to experience, high rates of inflation, high interest rates, exchange rate fluctuations, large amounts of external debt, balance of payments and trade difficulties and extreme poverty and unemployment. Many of these countries are also characterized by political uncertainty and instability. The cost of servicing external debt will generally be adversely affected by rising international interest rates because many external debt obligations bear interest at rates which are adjusted based upon international interest rates. The Fund also may purchase ADRs or U.S. dollar-denominated securities of foreign issuers. ADRs are receipts issued by U.S. banks or trust companies in respect of securities of foreign issuers held on deposit for use in the U.S. 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 shareholder communications to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited securities. The following provides more detail on certain pronounced risks with foreign investing:
| ● | Foreign Currency Risk. The Fund may invest in companies whose securities are denominated or quoted in currencies other than U.S. dollars or have significant operations or markets outside of the United States. In such instances, the Fund will be exposed to currency risk, including the risk of fluctuations in the exchange rate between U.S. dollars (in which the Fund’s shares are denominated) and such foreign currencies, the risk of currency devaluations and the risks of non-exchangeability and blockage. As non-U.S. securities may be purchased with and payable in currencies of countries other than the U.S. dollar, the value of these assets measured in U.S. dollars may be affected favorably or unfavorably by changes in currency rates and exchange control regulations. Fluctuations in currency rates may adversely affect the ability of the Investment Adviser to acquire such securities at advantageous prices and may also adversely affect the performance of such assets.
Certain non-U.S. currencies, primarily in developing countries, have been devalued in the past and might face devaluation in the future. Currency devaluations generally have a significant and adverse impact on the devaluing country’s economy in the short and intermediate term and on the financial condition and results of companies’ operations in that country. Currency devaluations may also be accompanied by significant declines in the values and liquidity of equity and debt securities of affected governmental and private sector entities generally. To the extent that affected companies have obligations denominated in currencies other than the devalued currency, those companies may also have difficulty in meeting those obligations under such circumstances, which in turn could have an adverse effect upon the value of the Fund’s investments in such companies. There can be no assurance that current or future developments with respect to foreign currency devaluations will not impair the Fund’s investment flexibility, its ability to achieve its investment objective or the value of certain of its foreign currency-denominated investments.
| ● | Tax Consequences of Foreign Investing. The Fund’s transactions in foreign currencies, foreign currency-denominated debt obligations and certain foreign currency options, futures contracts and forward contracts (and similar instruments) may give rise to ordinary income or loss to the extent such income or loss results from fluctuations in the value of the foreign currency concerned. This treatment could increase or decrease the Fund’s ordinary income distributions to you, and may cause some or all of the Fund’s previously distributed income to be classified as a return of capital. In certain cases, the Fund may make an election to treat gain or loss attributable to certain investments as capital gain or loss.
| ● | EMU and Redenomination Risk. As the European debt crisis progressed, the possibility of one or more Eurozone countries exiting the European Monetary Union (“EMU”), or even the collapse of the euro as a common currency, arose, creating significant volatility at times in currency and financial markets generally. The effects of the collapse of the euro, or of the exit of one or more countries from the EMU, on the U.S. and global economies and securities markets are impossible to predict and any such events could have a significant adverse impact on the value and risk profile of the Fund’s portfolio. Any partial or complete dissolution of the EMU could have significant adverse effects on currency and financial markets, and on the values of the Fund’s portfolio investments. If one or more EMU countries were to stop using the euro as its primary currency, the Fund’s investments in such countries may be redenominated into a different or newly adopted currency. As a result, the value of those investments could decline significantly and unpredictably. In addition, securities or other investments that are redenominated may be subject to foreign currency risk, liquidity risk and valuation risk to a greater extent than similar investments currently denominated in euros. To the extent a currency used for redenomination purposes is not specified in respect of certain EMU-related investments, or should the euro cease to be used entirely, the currency in which such investments are denominated may be unclear, making such investments particularly difficult to value or dispose of. The Fund may incur additional expenses to the extent it is required to seek judicial or other clarification of the denomination or value of such securities.
| ● | Eurozone Risk. A number of countries in the EU have experienced, and may continue to experience, severe economic and financial difficulties, increasing the risk of investing in the European markets. In particular, many EU nations are susceptible to economic risks associated with high levels of debt, notably due to investments in sovereign debt of countries such as Greece, Italy, Spain, Portugal, and Ireland. As a result, financial markets in the EU have been subject to increased volatility and declines in asset values and liquidity. Responses to these financial problems by European governments, central banks, and others, including austerity measures and reforms, may not work, may result in social unrest, and may limit future growth and economic recovery or have other unintended consequences. Further defaults or restructurings by governments and others of their debt could have additional adverse effects on economies, financial markets, and asset valuations around the world. Greece, Ireland, and Portugal have already received one or more “bailouts” from other Eurozone member states, and it is unclear how much additional funding they will require or if additional Eurozone member states will require bailouts in the future. One or more other countries may also abandon the euro and/or withdraw from the EU, placing
its currency and banking system in jeopardy. The impact of these actions, especially if they occur in a disorderly fashion, is not clear, but could be significant and far-reaching.
| ● | Brexit Risk. On January 31, 2020, the United Kingdom officially withdrew from the EU, commonly referred to as “Brexit.” Following a transition period, the United Kingdom and the EU signed a Trade and Cooperation Agreement (“UK/EU Trade Agreement”), which came into full force on May 1, 2021 and set out the foundation of the economic and legal framework for trade between the United Kingdom and the EU. As the UK/EU Trade Agreement is a new legal framework, the implementation of the UK/EU Trade Agreement may result in uncertainty in its application and periods of volatility in both the United Kingdom and wider European markets. The United Kingdom’s exit from the EU is expected to result in additional trade costs and disruptions in this trading relationship. Furthermore, there is the possibility that either party may impose tariffs on trade in the future in the event that regulatory standards between the EU and the UK diverge. The terms of the future relationship may cause continued uncertainty in the global financial markets, and adversely affect our ability, and the ability of our portfolio companies, to execute our respective strategies and to receive attractive returns.
In particular, currency volatility may mean that our returns and the returns of our portfolio companies will be adversely affected by market movements and may make it more difficult, or more expensive, for us to implement appropriate currency hedging. Potential declines in the value of the British Pound and/or the euro against other currencies, along with the potential downgrading of the United Kingdom’s sovereign credit rating, may also have an impact on the performance of any of our portfolio companies located in the United Kingdom or Europe. In addition, certain European countries have experienced negative interest rates on certain fixed-income instruments. A negative interest rate policy is an unconventional central bank monetary policy tool where nominal target interest rates are set with a negative value (i.e., below zero percent) intended to help create self-sustaining growth in the local economy. Negative interest rates may result in heightened market volatility and may detract from the Fund’s performance to the extent the Fund is exposed to such interest rates. Among other things, these developments adversely affected the value and exchange rate of the euro and pound sterling, and any similar developments may continue to significantly affect the economies of all EU countries, which in turn may have a material adverse effect on the Fund’s investments in such countries, other countries that depend on EU countries for significant amounts of trade or investment, or issuers with exposure to debt issued by certain EU countries. To the extent the Fund has exposure to European markets or to transactions tied to the value of the euro, these events could negatively affect the value and liquidity of the Fund’s investments. All of these developments may continue to significantly affect the economies of all EU countries, which in turn may have a material adverse effect on the Fund’s investments in such countries, other countries that depend on EU countries for significant amounts of trade or investment, or issuers with exposure to debt issued by certain EU countries.
| ● | Russia. As a result of Russia’s military invasion of Ukraine in February 2022, the United States and other countries imposed broad-reaching political and economic sanctions on Russia, certain Russian allies believed to be providing them military or financial support, on private and public companies domiciled in Russia, including public issuers and banking and financial institutions, and on a variety of individuals.
These sanctions, combined with equivalent measures taken by foreign businesses ceasing operations in Russia, continue to adversely impact global financial markets, disrupt global supply chains, and impair the value and liquidity of issuers and funds that continue to maintain exposure to Russia and its allies, Russian investments, and sectors that can be impacted by restrictions on Russian imports and exports, such as the oil and gas industry. It is not possible to predict the duration or extent of longer-term consequences of this conflict, which could include further sanctions, retaliatory measures taken by Russia, embargoes, regional instability, geopolitical shifts and adverse effects on macroeconomic conditions, security conditions, currency exchange rates, and financial markets around the globe. Any of the foregoing consequences, including those we cannot yet predict, may negatively impact the Fund’s performance and the value of an investment in the Fund, even if the Fund does not have direct exposure to Russian issuers or issuers in other countries impacted by the invasion. In general terms, the overall negative impact to the Fund will depend on the extent to which the Fund is prohibited from selling or otherwise transacting in their investments at any given time and whether a fair market valuation can be readily obtained, particularly for any Russian currency-denominated investments and investments in US dollar-denominated American Depositary Receipts representing securities of Russian issuers. |  |  |  |  |  |  |  |  |
Restricted And Illiquid Securities [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
General Description of Registrant [Abstract] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Risk [Text Block] |  |  |  |  |  |  |  |  |  | Restricted and Illiquid Securities. Unregistered securities are securities that cannot be sold publicly in the United States without registration under the Securities Act. An illiquid investment is a security or other investment that cannot be disposed of within seven days in the ordinary course of business at approximately the value at which the Fund has valued the investment. Unregistered securities often can be resold only in privately negotiated transactions with a limited number of purchasers or in a public offering registered under the Securities Act. Considerable delay could be encountered in either event and, unless otherwise contractually provided for, the Fund’s proceeds upon sale may be reduced by the costs of registration or underwriting discounts. The difficulties and delays associated with such transactions could result in the Fund’s inability to realize a favorable price upon disposition of unregistered securities, and at times might make disposition of such securities impossible. The Fund may be unable to sell illiquid investments when it desires to do so, resulting in the Fund obtaining a lower price or being required to retain the investment. Illiquid investments generally must be valued at fair value, which is inherently less precise than utilizing market values for liquid investments, and may lead to differences between the price at which a security is valued for determining the Fund’s net asset value and the price the Fund actually receives upon sale. |  |  |  |  |  |  |  |  |
Short Sales Risk [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
General Description of Registrant [Abstract] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Risk [Text Block] |  |  |  |  |  |  |  |  |  | Short Sales Risk. Short-selling involves selling securities which may or may not be owned and borrowing the same securities for delivery to the purchaser, with an obligation to replace the borrowed securities at a later date. If the price of the security sold short increases between the time of the short sale and the time the Fund replaces the borrowed security, the Fund will incur a loss; conversely, if the price declines, the Fund will realize a capital gain. Any gain will be decreased, and any loss will be increased, by the transaction costs incurred by the Fund, including the costs associated with providing collateral to the broker-dealer (usually cash and liquid securities). Although the Fund’s gain is limited to the price at which it sold the security short, its potential loss is theoretically unlimited. Short-selling necessarily involves certain additional risks. However, if the short seller does not own the securities sold short (an uncovered short sale), the borrowed securities must be replaced by securities purchased at market prices in order to close out the short position, and any appreciation in the price of the borrowed securities would result in a loss. Uncovered short sales expose the Fund to the risk of uncapped losses until a position can be closed out due to the lack of an upper limit on the price to which a security may rise. Purchasing securities to close out the short position can itself cause the price of the securities to rise further, thereby exacerbating the loss. There is the risk that the securities borrowed by the Fund in connection with a short-sale must be returned to the securities lender on short notice. If a request for return of borrowed securities occurs at a time when other short-sellers of the security are receiving similar requests, a “short squeeze” can occur, and the Fund may be compelled to replace borrowed securities previously sold short with purchases on the open market at the most disadvantageous time, possibly at prices significantly in excess of the proceeds received at the time the securities were originally sold short. In September 2008, in response to spreading turmoil in the financial markets, the SEC temporarily banned short selling in the stocks of numerous financial services companies, and also promulgated new disclosure requirements with respect to short positions held by investment managers. The SEC’s temporary ban on short selling of such stocks has since expired, but should similar restrictions and/or additional disclosure requirements be promulgated, especially if market turmoil occurs, the Fund may be forced to cover short positions more quickly than otherwise intended and may suffer losses as a result. Such restrictions may also adversely affect the ability of the Fund to execute its investment strategies generally. Similar emergency orders were also instituted in non-U.S. markets in response to increased volatility. The Fund’s ability to engage in short sales is also restricted by various regulatory requirements relating to short sales. |  |  |  |  |  |  |  |  |

Risk [Text Block] |  |  |  |  |  |  |  |  |  | Leverage Risk. The Fund currently uses financial leverage for investment purposes by issuing preferred shares. As of December 31, 2023, the amount of leverage represented approximately 30% of the Fund’s net assets. The Fund’s leveraged capital structure creates special risks not associated with unleveraged funds that have a similar investment objective and policies. These include the possibility of greater loss and the likelihood of higher volatility of the net asset value of the Fund and the asset coverage for any preferred shares or debt outstanding. Such volatility may increase the likelihood of the Fund having to sell investments in order to meet its obligations to make distributions on the preferred shares or principal or interest payments on debt securities, or to redeem preferred shares or repay debt when it may be disadvantageous to do so. The Fund’s use of leverage may require it to sell portfolio investments at inopportune times in order to raise cash to redeem preferred shares or otherwise de-leverage so as to maintain required asset coverage amounts or comply with the mandatory redemption terms of any outstanding preferred shares. The use of leverage magnifies both the favorable and unfavorable effects of price movements in the investments made by the Fund. To the extent the Fund is leveraged in its investment operations, the Fund will be subject to substantial risk of loss. The Fund cannot assure that borrowings or the issuance of notes or preferred shares will result in a higher yield or return to the holders of the common shares. Also, to the extent the Fund utilizes leverage, a decline in net asset value could affect the ability of the Fund to make common share distributions and such a failure to make distributions could result in the Fund ceasing to qualify as a RIC under the Code. For more information regarding the risks of a leverage capital structure to holders of the Fund’s common shares, see “Risk Factors and Special Considerations — Special Risks to Holder of Common Shares — Leverage Risk.” |  |  |  |  |  |  |  |  |
Special Risks Related To Investmentin Derivatives [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] |  |  |  |  |  |  |  |  |  | Special Risks Related to Investment in Derivatives. The Fund may participate in certain derivative transactions, as described herein. Such transactions entail certain execution, market, liquidity, counterparty, correlation, volatility, hedging and tax risks. Participation in derivatives 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 or other referenced instruments or markets is inaccurate, the consequences to the Fund may leave the Fund in a worse position than if it had not used such strategies. Risks inherent in the use of derivatives transactions include:
| ● | dependence on the Investment Adviser’s ability to predict correctly movements in the direction of the relevant measure;
| ● | imperfect correlation between the price of the derivative instrument and movements in the prices of the referenced assets;
| ● | 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 or instrument at a time that otherwise would be favorable for it to do so, or the possible need for the Fund to sell a security or instrument at a disadvantageous time due to a need for the Fund to remain in compliance with the 1940 Act restrictions regarding derivatives transactions; and
| ● | the creditworthiness of counterparties.
Certain derivatives 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 derivatives are traded may impose limits on the positions that the Fund may take in certain circumstances. 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 net asset value and may materially adversely affect the Fund in situations in which the Fund is required to sell derivative instruments. 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. Future CFTC or SEC rulemakings could potentially further limit or completely restrict the Fund’s ability to use these instruments as a part of the Fund’s investment strategy, increase the costs of using these instruments or make them less effective. Limits or restrictions applicable to the counterparties with which the Fund engages in derivative transactions could also prevent the Fund from using these instruments or affect the pricing or other factors relating to these instruments or may change the availability of certain investments. New regulation may make derivatives more costly, may limit the availability of derivatives, or may otherwise adversely affect the value or performance of derivatives. |  |  |  |  |  |  |  |  |
Counterparty Risk [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
General Description of Registrant [Abstract] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Risk [Text Block] |  |  |  |  |  |  |  |  |  | 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. The counterparty risk for cleared derivatives is generally lower than for uncleared OTC derivative transactions since generally a clearing organization becomes substituted for each counterparty to a cleared derivative contract and, in effect, guarantees the parties’ performance under the contract as each party to a trade looks only to the clearing organization for performance of financial obligations under the derivative contract. However, there can be no assurance that a clearing organization, or its members, will satisfy its obligations to the Fund, or that the Fund would be able to recover the full amount of assets deposited on its behalf with the clearing organization in the event of the default by the clearing organization or the Fund’s clearing broker. In addition, cleared derivative transactions benefit from daily marking-to-market and settlement, and segregation and minimum capital requirements applicable to intermediaries. Uncleared OTC derivative transactions generally do not benefit from such protections. This exposes the Fund to the risk that a counterparty will not settle a transaction in accordance with its terms and conditions because of a dispute over the terms of the contract (whether or not bona fide) or because of a credit or liquidity problem, thus causing the Fund to suffer a loss. Such “counterparty risk” is accentuated for contracts with longer maturities where events may intervene to prevent settlement, or where the Fund has concentrated its transactions with a single or small group of counterparties. |  |  |  |  |  |  |  |  |
Failure Of Futures Commission Merchants And Clearing Organizations Risk [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
General Description of Registrant [Abstract] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Risk [Text Block] |  |  |  |  |  |  |  |  |  | Failure of Futures Commission Merchants and Clearing Organizations Risk. The Fund may deposit funds required to margin open positions in the derivative instruments subject to the CEA with a clearing broker registered as a “futures commission merchant” (“FCM”). The CEA requires an FCM to segregate all funds received from customers with respect to any orders for the purchase or sale of U.S. domestic futures contracts and cleared swaps from the FCM’s proprietary assets. Similarly, the CEA requires each FCM to hold in a separate secure account all funds received from customers with respect to any orders for the purchase or sale of foreign futures contracts and segregate any such funds from the funds received with respect to domestic futures contracts. However, all funds and other property received by a clearing broker from its customers are held by the clearing broker on a commingled basis in an omnibus account and may be invested by the clearing broker in certain instruments permitted under the applicable regulation. There is a risk that assets deposited by the Fund with any swaps or futures clearing broker as margin for futures contracts may, in certain circumstances, be used to satisfy losses of other clients of the Fund’s clearing broker. In addition, the assets of the Fund may not be fully protected in the event of the clearing broker’s bankruptcy, as the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing broker’s combined domestic customer accounts. Similarly, the CEA requires a clearing organization approved by the CFTC as a derivatives clearing organization to segregate all funds and other property received from a clearing member’s clients in connection with domestic futures, swaps and options contracts from any funds held at the clearing organization to support the clearing member’s proprietary trading. Nevertheless, with respect to futures contracts and options on futures, a clearing organization may use assets of a non-defaulting customer held in an omnibus account at the clearing organization to satisfy losses in that account resulting from the default by another customer on its payment obligations that leads to the clearing member’s default to the clearing organization. As a result, in the situation of a double default by a customer of the Fund’s clearing member and the clearing member itself with respect to payment obligations on the customer’s futures or options on futures, there is a risk that the Fund’s assets in an omnibus account with the clearing organization may be used to satisfy losses from the double default and that the Fund may not recover the full amount of any such assets. |  |  |  |  |  |  |  |  |
Swaps Risk [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
General Description of Registrant [Abstract] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Risk [Text Block] |  |  |  |  |  |  |  |  |  | Swaps Risk. Swap agreements are two-party contracts entered into primarily by institutional investors for periods ranging from a few weeks to more than one year. In a standard “swap” transaction, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on particular predetermined investments or instruments. The gross returns to be exchanged or “swapped” between the parties are calculated with respect to a “notional amount,” i.e., the return on or increase in value of a particular dollar amount invested at a particular interest rate, in a particular foreign currency, or in a “basket” of securities representing a particular index. The “notional amount” of the swap agreement is only a fictive basis on which to calculate the obligations that the parties to a swap agreement have agreed to exchange. Historically, swap transactions have been individually negotiated non-standardized transactions entered into in the OTC markets and have not been subject to the same type of government regulation as exchange-traded instruments. However, in the U.S., the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”) has made broad changes to the derivatives market, granted significant new authority to the CFTC and the SEC to regulate derivatives (swaps and security-based swaps) and participants in these markets. The Dodd-Frank Act is intended to regulate the derivatives market by requiring many derivative transactions to be cleared and traded on an exchange, expanding entity registration requirements, imposing business conduct requirements on dealers and requiring banks to move some derivatives trading units to a non-guaranteed affiliate separate from the deposit-taking bank or divest them altogether. See “Risk Factors and Special Considerations—General Risks – Derivatives Regulation Risk.” Swap agreements will tend to shift the Fund’s investment exposure from one type of investment to another. For example, if the Fund agreed to pay fixed rates in exchange for floating rates while holding fixed-rate bonds, the swap would tend to decrease the Fund’s exposure to long-term interest rates. Caps and floors have an effect similar to buying or writing options. Depending on how they are used, swap agreements may increase or decrease the overall volatility of the Fund’s investments and its share price and yield. The most significant factor in the performance of swap agreements is the change in the specific interest rate, currency, or other factors that determine the amounts of payments due to and from the Fund. If a swap agreement calls for payments by the Fund, the Fund must be prepared to make such payments when due. The Fund may enter into swap agreements that would calculate the obligations of the parties to the agreements on a “net” basis. Consequently, the Fund’s obligations (or rights) under a swap agreement will generally be equal only to the net amount to be paid or received under the agreement based on the relative values of the positions held by each party to the agreement (the “net amount”). The Fund’s use of swap agreements may not be successful in furthering its investment objective, as the Investment Adviser may not accurately predict whether certain types of investments are likely to produce greater returns than other investments. Moreover, 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. The Fund may be able to eliminate its exposure under a swap agreement either by assignment or other disposition, or by entering into an offsetting swap agreement with the same party or a similarly creditworthy party. |  |  |  |  |  |  |  |  |
Forward Foreign Currency Exchange Contracts [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] |  |  |  |  |  |  |  |  |  | Forward Foreign Currency Exchange Contracts. The Fund may enter into forward foreign currency exchange contracts to protect the value of its portfolio against uncertainty in the level of future currency exchange rates between a particular foreign currency and the U.S. dollar or between foreign currencies in which its securities are or may be denominated. The Fund may enter into such contracts on a spot (i.e., cash) basis at the rate then prevailing in the currency exchange market or on a forward basis, by entering into a forward contract to purchase or sell currency. A forward contract on foreign currency is an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days agreed upon by the parties from the date of the contract at a price set on the date of the contract. Forward currency contracts (i) are traded in a market conducted directly between currency traders (typically, commercial banks or other financial institutions) and their customers, (ii) generally have no deposit requirements and (iii) are typically consummated without payment of any commissions. The Fund, however, may enter into forward currency contracts requiring deposits or involving the payment of commissions. The dealings of the Fund in forward foreign exchange are limited to hedging involving either specific transactions or portfolio positions. Transaction hedging is the purchase or sale of one forward foreign currency for another currency with respect to specific receivables or payables of the Fund accruing in connection with the purchase and sale of its portfolio securities or its payment of distributions. Position hedging is the purchase or sale of one forward foreign currency for another currency with respect to portfolio security positions denominated or quoted in the foreign currency to offset the effect of an anticipated substantial appreciation or depreciation, respectively, in the value of the currency relative to the U.S. dollar. In this situation, the Fund also may, for example, enter into a forward contract to sell or purchase a different foreign currency for a fixed U.S. dollar amount where it is believed that the U.S. dollar value of the currency to be sold or bought pursuant to the forward contract will fall or rise, as the case may be, whenever there is a decline or increase, respectively, in the U.S. dollar value of the currency in which its portfolio securities are denominated (this practice being referred to as a “cross-hedge”). In hedging a specific transaction, the Fund may enter into a forward contract with respect to either the currency in which the transaction is denominated or another currency deemed appropriate by the Investment Adviser. The amount the Fund may invest in forward currency contracts is limited to the amount of its aggregate investments in foreign currencies. The use of forward currency contracts may involve certain risks, including the failure of the counterparty to perform its obligations under the contract, and such use 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. The Fund will only enter into forward currency contracts with parties which the Investment Adviser believes to be creditworthy institutions. |  |  |  |  |  |  |  |  |

Risk [Text Block] |  |  |  |  |  |  |  |  |  | Futures Contracts and Options on Futures. 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 on price fluctuations; imperfect correlation between the contracts and the securities being hedged; and losses from investing in futures transactions that are potentially unlimited. |  |  |  |  |  |  |  |  |

Risk [Text Block] |  |  |  |  |  |  |  |  |  | Options Risk. To the extent that the Fund purchases options pursuant to a hedging strategy, the Fund will be subject to the following additional risks. If a put or call option purchased by the Fund is not sold when it has remaining value, and if the market price of the underlying security remains equal to or greater than the exercise price (in the case of a put), or remains less than or equal to the exercise price (in the case of a call), the Fund will lose its entire investment in the option. Where a put or call option on a particular security is purchased to hedge against price movements in that or a related security, the price of the put or call option may move more or less than the price of the security. If restrictions on exercise are imposed, the Fund may be unable to exercise an option it has purchased. If the Fund is unable to close out an option that it has purchased on a security, it will have to exercise the option in order to realize any profit or the option may expire worthless. |  |  |  |  |  |  |  |  |

Risk [Text Block] |  |  |  |  |  |  |  |  |  | Derivatives Regulation Risk. The Dodd-Frank Act has made broad changes to the derivatives market, granted significant new authority to the CFTC and the SEC to regulate derivatives (swaps and security-based swaps) and participants in these markets. The Dodd-Frank Act is intended to regulate the derivatives market by requiring many derivative transactions to be cleared and traded on an exchange, expanding entity registration requirements, imposing business conduct requirements on dealers and requiring banks to move some derivatives trading units to a non-guaranteed affiliate separate from the deposit-taking bank or divest them altogether. The CFTC has implemented mandatory clearing and exchange-trading of certain derivatives contracts including many standardized interest rate swaps and credit default index swaps. The CFTC continues to approve contracts for central clearing. Exchange-trading and central clearing are expected to reduce counterparty credit risk by substituting the clearinghouse as the counterparty to a swap and increase liquidity, but exchange-trading and central clearing do not make swap transactions risk-free. Uncleared swaps, such as non-deliverable foreign currency forwards, are subject to certain margin requirements that mandate the posting and collection of minimum margin amounts. This requirement may result in the Fund and its counterparties posting higher margin amounts for uncleared swaps than would otherwise be the case. Certain rules require centralized reporting of detailed information about many types of cleared and uncleared swaps. Reporting of swap data may result in greater market transparency, but may subject the Fund to additional administrative burdens, and the safeguards established to protect trader anonymity may not function as expected. |  |  |  |  |  |  |  |  |

Risk [Text Block] |  |  |  |  |  |  |  |  |  | Market Discount Risk. Whether investors will realize gains or losses upon the sale of additional securities of the Fund will depend upon the market price of the securities at the time of sale, which may be less or more than the Fund’s net asset value per share or the liquidation value of any Fund preferred shares issued. Since the market price of any additional securities the Fund may issue will be affected by such factors as the Fund’s dividend and distribution levels (which are in turn affected by expenses), dividend and distribution stability, net asset value, market liquidity, the relative demand for and supply of such securities in the market, general market and economic conditions and other factors beyond the control of the Fund, we cannot predict whether any such securities will trade at, below or above net asset value or at, below or above their public offering price or at, below or above their liquidation value, as applicable. For example, common shares of closed-end funds often trade at a discount to their net asset values and the Fund’s common shares may trade at such a discount. This risk may be greater for investors expecting to sell their securities of the Fund soon after the completion of a public offering for such securities. The risk of a market price discount from net asset value is separate and in addition to the risk that net asset value itself may decline. The Fund’s securities are designed primarily for long-term investors, and investors in the shares should not view the Fund as a vehicle for trading purposes. |  |  |  |  |  |  |  |  |

Risk [Text Block] |  |  |  |  |  |  |  |  |  | Long Term Objective; Not a Complete Investment Program. The Fund is intended for investors seeking a consistent level of after-tax total return consisting of income (with a current emphasis on qualifying dividends) and long-term capital gain. The Fund is not meant to provide a vehicle for those who wish to play short-term swings in the stock market. An investment in shares of the Fund should not be considered a complete investment program. Each shareholder should take into account the Fund’s investment objective as well as the shareholder’s other investments when considering an investment in the Fund. |  |  |  |  |  |  |  |  |

Risk [Text Block] |  |  |  |  |  |  |  |  |  | Management Risk. The Fund is subject to management risk because it is an actively managed portfolio. The Investment Adviser will apply 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. |  |  |  |  |  |  |  |  |

Investors have no authority to make decisions or to exercise business discretion on behalf of the Fund, except as set forth in the Fund’s governing documents. The authority for all such decisions is generally delegated to the Board, who in turn, has delegated the day-to-day management of the Fund’s investment activities to the Investment Adviser, subject to oversight by the Board. |  |  |  |  |  |  |  |  |

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. |  |  |  |  |  |  |  |  |
Market Disruption And Geopolitical Risk [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
General Description of Registrant [Abstract] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Risk [Text Block] |  |  |  |  |  |  |  |  |  | Market Disruption and Geopolitical Risk. General economic and market conditions, such as interest rates, availability of credit, inflation rates, economic uncertainty, supply chain disruptions, labor shortages, energy and other resource shortages, changes in laws, trade barriers, currency exchange controls and national and international political circumstances (including governmental responses to public health crises or the spread of infectious diseases), may have long-term negative effects on the U.S. and worldwide financial markets and economy. 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 Company, 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. Risks resulting from any future debt or other economic crisis could also have a detrimental impact on the global economy, the financial condition of financial institutions and the Fund’s 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, the Fund 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 objectives. The occurrence of events similar to those in recent years, such as localized wars, instability, new and ongoing pandemics, epidemics or outbreaks of infectious diseases in certain parts of the world, and catastrophic events such as fires, floods, earthquakes, tornadoes, hurricanes and global health epidemics, terrorist attacks in the U.S. and around the world, social and political discord, debt crises sovereign debt downgrades, increasingly strained relations between the U.S. 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 EU or the EMU, 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 U.S. and worldwide. In particular, the consequences of the Russian military invasion of Ukraine, the impact on inflation and increased disruption to supply chains and energy resources may impact the Fund’s 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 net asset values. In response to the conflict between Russia and Ukraine, the U.S. and other countries have imposed sanctions or other restrictive actions against Russia, Russian-backed separatist regions in Ukraine, and certain banks, companies, government officials and other individuals in Russia and Belarus. Any of the above factors, including sanctions, export controls, tariffs, trade wars and other governmental actions, could have a material adverse effect on the Fund. The Fund has no way to predict the duration or outcome of the situation, as the conflict and government reactions are rapidly developing and beyond the Fund’s control. Prolonged unrest, military activities, or broad-based sanctions could have a material adverse effect on companies in which the Fund invests. Such consequences also may increase such companies’ funding costs or limit their access to the capital markets. The current political climate has intensified concerns about a potential trade war between China and the U.S., as each country has 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 the Fund’s 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 the Fund. 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. |  |  |  |  |  |  |  |  |

Risk [Text Block] |  |  |  |  |  |  |  |  |  | Economic Events and Market Risk. Periods of market volatility remain, and 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 objectives. |  |  |  |  |  |  |  |  |
Regulation And Government Intervention Risk [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
General Description of Registrant [Abstract] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Risk [Text Block] |  |  |  |  |  |  |  |  |  | Regulation and Government Intervention Risk. Changes enacted by the current presidential administration could significantly impact the regulation of financial markets in the U.S. Areas subject to potential change, amendment or repeal include trade and foreign policy, corporate tax rates, energy and infrastructure policies, the environment and sustainability, criminal and social justice initiatives, immigration, healthcare and the oversight of certain federal financial regulatory agencies and the Federal Reserve. Certain of these changes can, and have, been effectuated through executive order. For example, the current administration has taken steps to rejoin the Paris climate accord of 2015 and incentivize certain clean energy technologies, cancel the Keystone XL pipeline, provide military support to Ukraine and change immigration enforcement priorities. Other potential changes that could be pursued by the current presidential administration could include an increase in the corporate income tax rate; changes to regulatory enforcement priorities; and spending on clean energy and infrastructure. It is not possible to predict which, if any, of these actions will be taken or, if taken, their effect on the economy, securities markets or the financial stability of the U.S. 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 the Fund’s ability to achieve its investment objectives. Additional risks arising from the differences in expressed policy preferences among the various constituencies in the branches of the U.S. government has led in the past, and may lead in the future, to short-term or prolonged policy impasses, which could, and has, resulted in shutdowns of the U.S. federal government. U.S. federal government shutdowns, especially prolonged shutdowns, could have a significant adverse impact on the economy in general and could impair the ability of issuers to raise capital in the securities markets. Any of these effects could have a material adverse effect on the Fund’s net asset value. In addition, the rules dealing with the U.S. federal income taxation are constantly under review by persons involved in the legislative process and by the IRS and the U.S. Treasury Department. The Tax Cuts and Jobs Act made substantial changes to the Code. Among those changes were a significant permanent reduction in the generally applicable corporate tax rate, changes in the taxation of individuals and other non-corporate taxpayers that generally but not universally reduce their taxes on a temporary basis subject to “sunset” provisions, the elimination or modification of various previously allowed deductions (including substantial limitations on the deductibility of interest and, in the case of individuals, the deduction for personal state and local taxes), certain additional limitations on the deduction of net operating losses, certain preferential rates of taxation on certain dividends and certain business income derived by non-corporate taxpayers in comparison to other ordinary income recognized by such taxpayers, and significant changes to the international tax rules. In addition, the Biden administration signed into law the Inflation Reduction Act, which modifies key aspects of the Code, including by creating an alternative minimum tax on certain corporations and an excise tax on stock repurchases by certain corporations. The effect of these and other changes is uncertain, both in terms of the direct effect on the taxation of an investment in the Fund’s shares and their indirect effect on the value of the Fund’s assets, Fund shares or market conditions generally. In addition, the U.S. government has proposed and adopted multiple regulations that could have a long-lasting impact on the Fund and on the closed-end fund industry in general. The SEC’s final rules and amendments that modernize reporting and disclosure, along with other potential upcoming regulations, could, among other things, restrict the Fund’s ability to engage in transactions, and/or increase overall expenses of the Fund. 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. 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’s investments may pay interest at floating rates based on LIBOR or may be subject to interest caps or floors based on LIBOR. The Fund may also obtain financing at floating rates based on LIBOR. Derivative instruments utilized by the Fund may also reference LIBOR. In July 2017, the head of the United Kingdom Financial Conduct Authority announced the desire to phase out the use of LIBOR by the end of 2021. LIBOR can no longer be used to calculate new deals as of December 31, 2021. Since December 31, 2021, all sterling, euro, Swiss franc and Japanese yen LIBOR settings and the 1-week and 2-month U.S. dollar LIBOR settings have ceased to be published or are no longer representative. Overnight and 12-month US dollar LIBOR settings permanently ceased as of June 30, 2023. 1-, 3-, and 6-month U.S. dollar LIBOR settings will continue to be published using a synthetic methodology until September 2024. Various financial industry groups have begun planning for the transition away from LIBOR, but there are challenges to converting certain securities and transactions to a new reference rate. Neither the effect of the LIBOR transition process nor its ultimate success can yet be known. As an alternative to LIBOR, the Financial Reporting Council, in conjunction with the Alternative Reference Rates Committee, a steering committee comprised of large U.S. financial institutions recommended replacing U.S. dollar LIBOR with the Secured Overnight Financing Rate (“SOFR”), a new index calculated by reference to short-term repurchase agreements, backed by Treasury securities. Abandonment of, or modifications to, LIBOR could have adverse impacts on newly issued financial instruments and any of our existing financial instruments which reference LIBOR. Given the inherent differences between LIBOR and SOFR, or any other alternative benchmark rate that may be established, there are many uncertainties regarding a transition from LIBOR, including, but not limited to, the need to amend all contracts with LIBOR as the referenced rate and how this will impact the cost of variable rate debt and certain derivative financial instruments. In addition, SOFR or other replacement rates may fail to gain market acceptance. Any failure of SOFR or alternative reference rates to gain market acceptance could adversely affect the return on, value of and market for securities linked to such rates. Neither the effect of the LIBOR transition process nor its ultimate success can yet be known. The transition process might lead to increased volatility and illiquidity in markets for, and reduce the effectiveness of, new hedges placed against, instruments whose terms currently include LIBOR. While some existing LIBOR-based instruments may contemplate a scenario where LIBOR is no longer available by providing for an alternative rate-setting methodology, there may be significant uncertainty regarding the effectiveness of any such alternative methodologies to replicate LIBOR. Not all existing LIBOR-based instruments may have alternative rate-setting provisions and there remains uncertainty regarding the willingness and ability of issuers to add alternative rate-setting provisions in certain existing instruments. Moreover, these alternative rate-setting provisions may not be designed for regular use in an environment where LIBOR ceases to be published, and may be an ineffective fallback following the discontinuation of LIBOR. On March 15, 2022, President Biden signed into law the Consolidated Appropriations Act of 2022, which among other things, provides for the use of interest rates based on SOFR in certain contracts currently based on LIBOR and a safe harbor from liability for utilizing SOFR-based interest rates as a replacement for LIBOR. The elimination of LIBOR could have an adverse impact on the market value of and/or transferability of any LIBOR-linked securities, loans, and other financial obligations or extensions of credit held by or due to us or on our overall financial condition or results of operations. |  |  |  |  |  |  |  |  |

Risk [Text Block] |  |  |  |  |  |  |  |  |  | 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. |  |  |  |  |  |  |  |  |
Legislation Risk [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] |  |  |  |  |  |  |  |  |  | Legislation Risk. At any time after the date of this Annual 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 [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] |  |  |  |  |  |  |  |  |  | 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 [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] |  |  |  |  |  |  |  |  |  | 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 are becoming increasingly common and more sophisticated, and may be perpetrated by computer hackers, cyber-terrorists or others engaged in corporate espionage. 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 net asset value; 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 have been a number of recent highly publicized cases of companies reporting the unauthorized disclosure of client or customer information, as well as cyberattacks involving the dissemination, theft and destruction of corporate information or other assets, as a result of failure to follow procedures by employees or contractors or as a result of actions by third parties, including actions by terrorist organizations and hostile foreign governments. Although service providers typically have policies and procedures, business continuity plans and/or risk management systems intended to identify and mitigate cyber incidents, there are inherent limitations in such plans and systems including the possibility that certain risks have not been identified. Furthermore, the Fund cannot control the cyber security policies, plans and systems put in place by its service providers or any other third parties whose operations may affect the Fund or its shareholders. 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. Because technology is consistently changing, new ways to carry out cyber attacks are always developing. Therefore, there is a chance that some risks have not been identified or prepared for, or that an attack may not be detected, which puts limitations on the Fund’s ability to plan for or respond to a cyber attack. In addition to deliberate cyber attacks, unintentional cyber incidents can occur, such as the inadvertent release of confidential information by the Fund or its service providers. Like other funds and business enterprises, the Fund and its service providers are subject to the risk of cyber incidents occurring from time to time. |  |  |  |  |  |  |  |  |

Risk [Text Block] |  |  |  |  |  |  |  |  |  | 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. |  |  |  |  |  |  |  |  |

Risk [Text Block] |  |  |  |  |  |  |  |  |  | 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 collateralized in accordance with applicable regulatory requirements. 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 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. |  |  |  |  |  |  |  |  |
Legal Tax And Regulatory Risk [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] |  |  |  |  |  |  |  |  |  | Legal, Tax and Regulatory Risk. Legal, tax and regulatory changes could occur that may have material adverse effects on the Fund or its shareholders. For example, the regulatory and tax environment for derivative instruments in which the Fund may participate is evolving, and such changes in the regulation or taxation of derivative instruments may have material adverse effects on the value of derivative instruments held by the Fund and the ability of the Fund to pursue its investment strategies. Similarly, the Biden administration has indicated that it intends to modify key aspects of the Code, including by increasing corporate and individual tax rates. Changes to the U.S. federal tax laws and interpretations thereof could adversely affect an investment in the Fund. We cannot assure you what percentage of the distributions paid on the Fund’s shares, if any, will consist of tax-advantaged qualified dividend income or long-term capital gains or what the tax rates on various types of income will be in future years. To qualify for the favorable U.S. federal income tax treatment generally accorded to RICs under the Code, the Fund must, among other things, meet certain asset diversification tests, derive in each taxable year at least 90% of its gross income from certain prescribed sources and distribute for each taxable year at least 90% of its “investment company taxable income.” Statutory limitations on distributions on the common shares if the Fund fails to satisfy the 1940 Act’s asset coverage requirements could jeopardize the Fund’s ability to meet such distribution requirements. While the Fund presently intends to purchase or redeem notes or preferred shares, if any, to the extent necessary in order to maintain compliance with such asset coverage requirements, there can be no assurance that such actions can be effected in time to meet the Code requirements. If for any taxable year the Fund does not qualify as a RIC, all of its taxable income for that year (including its net capital gain) would be subject to tax at regular corporate rates without any deduction for distributions to shareholders, and such distributions would be taxable as ordinary dividends to the extent of the Fund’s current and accumulated earnings and profits. The resulting corporate taxes would materially reduce the Fund’s net assets and the amount of cash available for distribution to shareholders. For a more complete discussion of these and other U.S. federal income tax considerations. |  |  |  |  |  |  |  |  |

Risk [Text Block] |  |  |  |  |  |  |  |  |  | Investment Dilution Risk. The Fund’s investors do not have preemptive rights to any shares the Fund may issue in the future. The Fund’s Agreement and Declaration of Trust authorizes it to issue an unlimited number of shares. The Board may make certain amendments to the Agreement and Declaration of Trust. After an investor purchases shares, the Fund may sell additional shares or other classes of shares in the future or issue equity interests in private offerings. To the extent the Fund issues additional equity interests after an investor purchases its shares, such investor’s percentage ownership interest in the Fund will be diluted. |  |  |  |  |  |  |  |  |

Risk [Text Block] |  |  |  |  |  |  |  |  |  | Special Risks to Holders of Notes An investment in our notes is subject to special risks. Our notes are not likely to be listed on an exchange or automated quotation system. We cannot assure you that any market will exist for our notes or if a market does exist, whether it will provide holders with liquidity. Broker-dealers that maintain a secondary trading market for the notes are not required to maintain this market, and the Fund is not required to redeem notes if an attempted secondary market sale fails because of a lack of buyers. To the extent that our notes trade, they may trade at a price either higher or lower than their principal amount depending on interest rates, the rating (if any) on such notes and other factors. |  |  |  |  |  |  |  |  |

Risk [Text Block] |  |  |  |  |  |  |  |  |  | Special Risks to Holders of Fixed Rate Preferred Shares Illiquidity Prior to Exchange Listing. Prior to an offering, there will be no public market for any series of fixed rate preferred shares. In the event any additional series of fixed rate preferred shares are issued, we expect to apply to list such shares on a national securities exchange, which will likely be the NYSE. However, during an initial period, which is not expected to exceed 30 days after the date of initial issuance, such shares may not be listed on any securities exchange. During such period, the underwriters may make a market in such shares, though they will have no obligation to do so. Consequently, an investment in such shares may be illiquid during such period. Market Price Fluctuation. Fixed rate preferred shares may trade at a premium to or discount from liquidation value for various reasons, including changes in interest rates, perceived credit quality and other factors. |  |  |  |  |  |  |  |  |

Risk [Text Block] |  |  |  |  |  |  |  |  |  | Special Risks to Holders of Notes and Preferred Shares Common Share Repurchases. Repurchases of common shares by the Fund may reduce the net asset coverage of the notes and preferred shares, which could adversely affect their liquidity or market prices. Common Share 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 expects that it would return capital as part of its distribution. This would decrease the asset coverage per share with respect to the Fund’s notes or preferred shares, which could adversely affect their liquidity or market prices. During the fiscal year ended December 31, 2023, the Fund made distributions of $1.20 per common share, or which $0.97 per common share comprised return of capital. The composition of each distribution is estimated based on earnings as of the record date for the distribution. The actual composition of each distribution may change based on the Fund’s investment activity through the end of the calendar year. Credit Quality Ratings. The Fund may obtain credit quality ratings for its preferred shares or notes, if desired; however, it is not required to do so and may issue preferred shares or notes without any rating. If rated, the Fund does not impose any minimum rating necessary to issue such preferred shares or notes. The Fund’s portfolio must satisfy over-collateralization tests established by the relevant rating agencies in order to obtain and maintain attractive credit quality ratings for preferred shares or borrowings, if desired. 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. 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 notes or preferred shares, a rating by a ratings agency does not eliminate or necessarily mitigate the risks of investing in our preferred shares or notes, 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 notes or preferred shares, which may make such securities less liquid in the secondary market. If a rating agency downgrades the rating assigned to our preferred shares or notes, we may alter our portfolio or redeem all or a portion of the preferred shares or notes that are then redeemable under certain circumstances. |  |  |  |  |  |  |  |  |

Risk [Text Block] |  |  |  |  |  |  |  |  |  | Special Risks of Notes to Holders of Preferred Shares As provided in the 1940 Act, and subject to compliance with the Fund’s investment limitations, the Fund may issue notes. In the event the Fund were to issue such securities, the Fund’s obligations to pay dividends or make distributions and, upon liquidation of the Fund, liquidation payments in respect of its preferred shares would be subordinate to the Fund’s obligations to make any principal and interest payments due and owing with respect to its outstanding notes. Accordingly, the Fund’s issuance of notes would have the effect of creating special risks for the Fund’s preferred shareholders that would not be present in a capital structure that did not include such securities. |  |  |  |  |  |  |  |  |
Special Risks To Holders Of Common Shares [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] |  |  |  |  |  |  |  |  |  | Special Risks to Holders of Common Shares Dilution Risk. If the Fund determines to conduct a rights offering to subscribe for common shares, holders of common shares may experience dilution or accretion of the aggregate net asset value of their common shares. Such dilution or accretion will depend upon whether (i) such shareholders participate in the rights offering and (ii) the Fund’s net asset value per common share is above or below the subscription price on the expiration date of the rights offering. Shareholders who do not exercise their subscription rights may, at the completion of such an offering, own a smaller proportional interest in the Fund than if they exercised their subscription rights. As a result of such an offering, a shareholder may experience dilution in net asset value per share if the subscription price per share is below the net asset value per share on the expiration date. If the subscription price per share is below the net asset value per share of the Fund’s shares on the expiration date, a shareholder will experience an immediate dilution of the aggregate net asset value of such shareholder’s shares if the shareholder does not participate in such an offering and the shareholder will experience a reduction in the net asset value per share of such shareholder’s shares whether or not the shareholder participates in such an offering. The Fund cannot state precisely the extent of this dilution (if any) if the shareholder does not exercise such shareholder’s subscription rights because the Fund does not know what the net asset value per share will be when the offer expires or what proportion of the subscription rights will be exercised. Leverage Risk. The Fund currently uses financial leverage for investment purposes by issuing preferred shares and is also permitted to use other types of financial leverage, such as through the issuance of debt securities or additional preferred shares and borrowing from financial institutions. As provided in the 1940 Act and subject to certain exceptions, the Fund may issue additional senior securities (which may be stock, such as preferred shares, and/or securities representing debt) only if immediately after such issuance the value of the Fund’s total assets, less certain ordinary course liabilities, exceeds 300% of the amount of the debt outstanding and exceeds 200% of the amount of preferred shares and debt outstanding. As of December 31, 2023, the amount of leverage represented approximately 30% of the Fund’s net assets. The Fund’s leveraged capital structure creates special risks not associated with unleveraged funds having a similar investment objective and policies. These include the possibility of greater loss and the likelihood of higher volatility of the net asset value of the Fund and the asset coverage for the preferred shares. Such volatility may increase the likelihood of the Fund having to sell investments in order to meet its obligations to make distributions on the preferred shares or principal or interest payments on debt securities, or to redeem preferred shares or repay debt, when it may be disadvantageous to do so. The Fund’s use of leverage may require it to sell portfolio investments at inopportune times in order to raise cash to redeem preferred shares or otherwise de- leverage so as to maintain required asset coverage amounts or comply with the mandatory redemption terms of any outstanding preferred shares. The use of leverage magnifies both the favorable and unfavorable effects of price movements in the investments made by the Fund. To the extent that the Fund employs leverage in its investment operations, the Fund is subject to substantial risk of loss. The Fund cannot assure you that borrowings or the issuance of notes or preferred shares will result in a higher yield or return to the holders of the common shares. Also, since the Fund utilizes leverage, a decline in net asset value could affect the ability of the Fund to make common share distributions and such a failure to make distributions could result in the Fund ceasing to qualify as a RIC under the Code. Any decline in the net asset value of the Fund’s investments would be borne entirely by the holders of common shares. Therefore, if the market value of the Fund’s portfolio declines, the leverage will result in a greater decrease in net asset value to the holders of common shares than if the Fund were not leveraged. This greater net asset value decrease will also tend to cause a greater decline in the market price for the common shares. The Fund might be in danger of failing to maintain the required asset coverage of its borrowings, notes or preferred shares or of losing its ratings on its notes or preferred shares or notes or, in an extreme case, the Fund’s current investment income might not be sufficient to meet the distribution or interest requirements on the borrowings, preferred shares or notes. In order to counteract such an event, the Fund might need to liquidate investments in order to fund a redemption or repayment of some or all of the borrowings, preferred shares or notes. Preferred Share and Note Risk. The issuance of preferred shares or notes causes the net asset value and market value of the common shares to become more volatile. If the dividend rate on the preferred shares or the interest rate on the notes approaches the net rate of return on the Fund’s investment portfolio, the benefit of leverage to the holders of the common shares would be reduced. If the dividend rate on the preferred shares or the interest rate on the notes plus the management fee rate exceeds the net rate of return on the Fund’s portfolio, the leverage will result in a lower rate of return to the holders of common shares than if the Fund had not issued preferred shares or notes. If the Fund has insufficient investment income and gains, all or a portion of the distributions to preferred shareholders or interest payments to note holders would come from the common shareholders’ capital. Such distributions and interest payments reduce the net assets attributable to common shareholders. The Prospectus Supplement relating to any sale of preferred shares will set forth dividend rate on such preferred shares. In addition, the Fund would pay (and the holders of common shares will bear) all costs and expenses relating to the issuance and ongoing maintenance of the preferred shares or notes, including the advisory fees on the incremental assets attributable to the preferred shares or notes. Holders of preferred shares and notes may have different interests than holders of common shares and may at times have disproportionate influence over the Fund’s affairs. As provided in the 1940 Act and subject to certain exceptions, the Fund may issue senior securities (which may be stock, such as preferred shares, and/or securities representing debt, such as notes) only if immediately after the issuance the value of the Fund’s total assets, less certain ordinary course liabilities, exceeds 300% of the amount of the debt outstanding (i.e., for every dollar of indebtedness outstanding, the Fund is required to have at least three dollars of assets) and exceeds 200% of the amount of preferred shares and debt outstanding (i.e., for every dollar in liquidation preference of preferred stock outstanding, the Fund is required to have two dollars of assets), which is referred to as the “asset coverage” required by the 1940 Act. In the event the Fund fails to maintain an asset coverage of 100% for any notes outstanding for certain periods of time, the 1940 Act requires that either an event of default be declared or that the holders of such notes have the right to elect a majority of the Fund’s Trustees until asset coverage recovers to 110%. In addition, holders of preferred shares, voting separately as a single class, have the right (subject to the rights of noteholders) to elect two members of the Board at all times and in the event dividends become two full years in arrears would have the right to elect a majority of the Trustees until such arrearage is completely eliminated. In addition, preferred shareholders 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. Further, interest on notes will be payable when due as described in a Prospectus Supplement and if the Fund does not pay interest when due, it will trigger an event of default and the Fund expects to be restricted from declaring dividends and making other distributions with respect to common shares and preferred shares. Upon the occurrence and continuance of an event of default, the holders of a majority in principal amount of a series of outstanding notes or the Trustee will be able to declare the principal amount of that series of notes immediately due and payable upon written notice to the Fund. The 1940 Act also generally restricts the Fund from declaring distributions on, or repurchasing, common or preferred shares unless notes have an asset coverage of 300% (200% in the case of declaring distributions on preferred shares). The Fund’s common shares are structurally subordinated as to income and residual value to any preferred shares or notes in the Fund’s capital structure, in terms of priority to income and payment in liquidation. Restrictions imposed on the declarations and payment of dividends or other distributions to the holders of the Fund’s common shares and preferred shares, both by the 1940 Act and by requirements imposed by rating agencies, might impair the Fund’s ability to maintain its qualification as a RIC for U.S. federal income tax purposes. While the Fund intends to redeem its preferred shares or notes to the extent necessary to enable the Fund to distribute its income as required to maintain its qualification as a RIC under the Code, there can be no assurance that such actions can be effected in time to meet the Code requirements.
| ● | Portfolio Guidelines of Rating Agencies for Preferred Shares and/or Credit Facility. In order to obtain and maintain attractive credit quality ratings for preferred shares or notes, the Fund must comply with investment quality, diversification and other guidelines established by the relevant rating agencies. 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 shares or notes is lowered or withdrawn by the relevant rating agency, the Fund may also be required to redeem all or part of its outstanding preferred shares or notes, and the common shares of the Fund will lose the potential benefits associated with a leveraged capital structure.
| ● | Impact on Common Shares. Assuming that leverage will (1) be equal in amount to approximately 30% of the Fund’s total net assets (the Fund’s amount of outstanding financial leverage at December 31, 2023), and (2) charge interest or involve dividend payments at a projected blended annual average leverage dividend or interest rate of 5.16%, then the total return generated by the Fund’s portfolio (net of estimated expenses) must exceed approximately 1.58% of the Fund’s total net assets in order to cover such interest or dividend payments and other expenses specifically related to leverage. Of course, 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 ta-ble is furnished in response to requirements of the SEC. It is designed to illustrate the effect of leverage on common share 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. The table further reflects leverage representing 30% of the Fund’s net assets (the Fund’s amount of outstanding financial leverage at December 31, 2023), the Fund’s current projected blended annual average leverage dividend or interest rate of 5.16% (the average dividend rate on the Fund’s outstanding financial leverage at December 31, 2023), a base management fee at an annual rate of 0.50% and estimated annual incremental expenses attributable to any outstanding preferred shares of approximately 0.04% of the Fund’s net assets attributable to common shares. 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.
Assumed Return on Portfolio (Net of Expenses) |  |  | (10 | )% |  |  | (5 | )% |  |  | 0 | % |  |  | 5 | % |  |  | 10 | %
Corresponding Return to Common Shareholder |  |  | (16.76 | )% |  |  | (9.61 | )% |  |  | (2.46 | )% |  |  | 4.70 | % |  |  | 11.85 | %
Common share 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 shares) 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.
| ● | Market Discount Risk. As described above in “—General Risks—Market Discount Risk,” common shares of closed-end funds often trade at a discount to their net asset values and the Fund’s common shares may trade at such a discount. This risk may be greater for investors expecting to sell their common shares of the Fund soon after completion of a public offering. The common shares of the Fund are designed primarily for long-term investors and investors in the shares should not view the Fund as a vehicle for trading purposes.

Risk [Text Block] |  |  |  |  |  |  |  |  |  | Special Risk to Holders of Subscription Rights There is a risk that changes in market conditions may result in the underlying common or preferred shares 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 common or preferred shares issued may be reduced, and the common or preferred shares may trade at less favorable prices than larger offerings for similar securities. |  |  |  |  |  |  |  |  |
