Total Expenses Incurred |  | $33 |  | $102 |  | $172 |  | $359
* | The example should not be considered a representation of future expenses. The example is based on total Annual Expenses and Dividends on Preferred Shares shown in the table above and assumes that the amounts set forth in the table do not change and that all distributions are reinvested at net asset value. Actual expenses may be greater or less than those assumed. Moreover, the Fund’s actual rate of return may be greater or less than the hypothetical 5% return shown in the example.
The example includes Dividends on Preferred Shares. If Dividends on Preferred Shares were not included in the example calculation, the expenses for the 1-, 3-, 5- and 10-year periods in the table above would be as follows (based on the same assumptions as above): $19, $59, $102, and $221. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Investment Objectives and Practices [Text Block] | INVESTMENT OBJECTIVES AND POLICIES Investment Objectives and Policies The Fund’s primary investment objective is to provide a high level of current income from interest, dividends and option premiums. The Fund’s secondary investment objective is to seek capital appreciation consistent with the Fund’s strategy and its primary objective. To meet the objective of providing a high level of current income, the Fund intends to invest in income producing securities such as equity securities, convertible securities and other securities and earn short-term gains from a strategy of writing covered call options on equity securities in its portfolio. The Fund will seek dividend income through investments in equity securities such as common stock or convertible preferred stock. The Fund will seek interest income through investments in convertible or corporate bonds. Under normal market conditions, the Fund will attempt to achieve its objectives by investing at least 80% of its assets, which includes the amount of any borrowings for investment purposes, in securities of companies principally engaged in the natural resources and gold industries. The Fund will invest at least 25% of its assets in the securities of companies principally engaged in the natural resources industry, which includes companies principally engaged in the exploration, production or distribution of natural resources, such as metals (including both precious metals—such as silver and platinum—and base (i.e., non-precious) metals—such as copper, lead, nickel and zinc), paper, food, agriculture, forestry products, water, gas, oil, sustainable energy and other commodities as well as related transportation companies and equipment manufacturers (“Natural Resources Companies”). Related transportation companies and equipment manufacturers, such as agriculture transportation vehicles and farm equipment manufacturers, are vital components of the natural resource industry and are therefore included within the definition of Natural Resources Companies. The Fund will invest at least 25% of its assets in the securities of companies principally engaged in the gold industry, which includes companies principally engaged in the exploration, mining, fabrication, processing, distribution or trading of gold or the financing, managing, controlling or operating of companies engaged in “gold-related” activities (“Gold Companies”). Companies principally engaged in the financing, managing, controlling or operating of companies engaged in “gold-related” activities include companies that own or receive royalties on the production of gold; such companies are vital components of the gold industry and are therefore included within the definition of Gold Companies. The Fund may invest without limitation in the securities of domestic and foreign issuers. The Fund expects that its assets will usually be invested in several countries. To the extent that the natural resources and gold industries are concentrated in any given geographic region, such as Europe, North America, Latin America or Asia, a relatively high proportion of the Fund’s assets may be invested in that particular region. Principally engaged, as used in this Annual Report, means a company that derives at least 50% of its revenues or earnings from or devotes at least 50% of its assets to the indicated businesses. Equity securities may include common stocks, preferred stocks, convertible securities, warrants, depositary receipts and equity interests in trusts and other entities. Other Fund investments may include investment companies, including exchange traded funds, securities of issuers subject to reorganization or other risk arbitrage investments, certain derivative instruments, debt (including obligations of the U.S. government) and money market instruments. As part of its investment strategy, the Fund intends to provide current income from short-term gains earned through an option strategy which will normally consist of writing (selling) call options on equity securities in its portfolio (“covered calls”), but may, in amounts up to 15% of the Fund’s assets, consist of writing uncovered call options on securities not held by the Fund and indices comprised of Natural Resources Companies or Gold Companies or exchange-traded funds comprised of such issuers and writing put options on securities of Natural Resource Companies or Gold Companies. When the Fund sells a call option, it generates current income from short-term gains in the form of the premium paid by the buyer of the call option, but the Fund forgoes the opportunity to participate in any increase in the value of the underlying equity security above the exercise price of the option. When the Fund sells a put option, it generates current income from short-term gains in the form of the premium paid by the buyer of the put option, but the Fund will have the obligation to buy the underlying security at the exercise price if the price of the security decreases below the exercise price of the option. Any premiums received by the Fund from writing options may result in short-term capital gains. The Fund may invest up to 20% of its assets in “convertible securities,” i.e., securities (bonds, debentures, notes, stocks and other similar securities) that are convertible into common stock or other equity securities, and “income securities,” i.e., nonconvertible debt or equity securities having a history of regular payments or accrual of income to holders. Under normal market conditions, the Fund may invest up to 35% of its assets in fixed-income securities. Short-term discounted Treasury Bills or certain short-term securities of U.S. government sponsored instrumentalities are not subject to this limitation. The Fund has no requirements as to maturity or duration of its fixed-income investments, and the Fund does not target any particular average duration or average maturity. The average duration and average maturity of the Fund’s fixed-income investments is expected to vary. The Fund may invest up to 25% of its assets in “junk bonds” such as convertible debt securities (which generally are rated lower than investment grade) and fixed-income securities that are rated lower than investment grade, or not rated but of similar quality as determined by the Investment Adviser. In selecting securities for the Fund, the Investment Adviser will use a bottom-up, value approach. The Investment Adviser will primarily focus on company-specific criteria rather than on political, economic or other country-specific factors. No assurance can be given that the Fund will achieve its investment objectives. The Fund’s investment objectives and its policies of investing at least 25% of its assets in normal circumstances in Natural Resources Companies and in Gold Companies are fundamental policies that cannot be changed without the affirmative vote of a majority, as defined in the 1940 Act, of the outstanding voting securities (voting together as a single class) of the Fund (which for this purpose and under the 1940 Act means the lesser of (i) 67% of the shares represented at a meeting at which more than 50% of the outstanding shares are represented or (ii) more than 50% of the outstanding shares). If the Fund issues and has outstanding preferred shares, the affirmative vote of the holders of a majority, as defined in the 1940 Act, of the outstanding preferred shares of the Fund voting as a separate class (which for this purposes and under the 1940 Act means the lesser of (i) 67% of the preferred shares, as a single class, represented at a meeting at which more than 50% of the Fund’s outstanding preferred shares are represented or (ii) more than 50% of the outstanding preferred shares) would also be required to change a fundamental policy. Unless specifically stated as such, no other policy of the Fund is fundamental and each policy may be changed by the Board without shareholder approval and the Fund will provide notice to shareholders of material changes. The Fund’s policy to invest at least 80% of its total assets in in securities of companies principally engaged in the natural resources and gold industries may be changed by the Board; however, if this policy changes, the Fund will provide shareholders at least 60 days’ written notice before implementation of the change in compliance with SEC rules. The percentage and ratings limitations stated herein apply only at the time of investment and are not considered violated as a result of subsequent changes to the value, or downgrades to the ratings, of the Fund’s portfolio investments. Gabelli Funds, LLC, a New York limited liability company, with offices at One Corporate Center, Rye, New York 10580-1422, serves as the investment adviser to the Fund. 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 ability of the Fund to generate current income from short-term 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 other 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 selecting investments in the gold industry and the natural resources industries is to emphasize quality and value, as determined by such factors as asset quality, balance sheet leverage, management ability, reserve life, cash flow, and commodity hedging exposure. In addition, in making stock selections, the Investment Adviser looks for securities that it believes may have a superior yield as well as capital gains potential. Certain Investment Practices Natural Resources Industries Concentration. Under normal market conditions, the Fund will invest at least 25% of its assets in Natural Resources Companies. “Natural Resources Companies” are those that are principally engaged in the exploration, production or distribution of natural resources, such as metals (including both precious metals—such as silver and platinum—and base (i.e., non-precious) metals—such as copper, lead, nickel and zinc), paper, food and agriculture, forestry products, gas, oil and other commodities as well as related transportation companies and equipment manufacturers. Related transportation companies and equipment manufacturers, such as agriculture transportation vehicles and farm equipment manufacturers, are vital components of the natural resource industry and are therefore included within the definition of Natural Resources Companies. Principally engaged, as used in this Annual Report, means a company that derives at least 50% of its revenues or earnings or devotes at least 50% of its assets to natural resources or gold related activities, as the case may be. Gold Industry Concentration. Under normal market conditions the Fund will invest at least 25% of its assets in Gold Companies. “Gold Companies” are those that are principally engaged in the exploration, mining, fabrication, processing, distribution or trading of gold, or the financing, managing, controlling or operating of companies engaged in “gold-related” activities. Companies principally engaged in the financing, managing, controlling or operating of companies engaged in “gold-related” activities include companies that own or receive royalties on the production of gold; such companies are vital components of the gold industry and are therefore included within the definition of Gold Companies. The Fund’s investments in Gold Companies will generally be in the common equity of Gold Companies, but the Fund may also invest in other securities of Gold Companies, such as preferred stocks, securities convertible into common stocks, and securities such as rights and warrants that have common stock characteristics. The Fund will not invest in gold bullion and therefore the Fund’s performance will not track directly the price of gold. In selecting investments in Gold Companies for the Fund, the Investment Adviser will focus on stocks that are undervalued, but which appear to have favorable prospects for growth. Factors considered in this determination will include capitalization per ounce of gold production, capitalization per ounce of recoverable reserves, quality of management and ability to create shareholder wealth. Because most of the world’s gold production is outside of the United States, the Fund may have a significant portion of its investments in Gold Companies in securities of foreign issuers, including those located in developed as well as emerging markets. The percentage of Fund assets invested in particular countries or regions will change from time to time based on the Investment Adviser’s judgment. Among other things, the Investment Adviser will consider the economic stability and economic outlook of these countries and regions. See “Risk Factors and Special Considerations—Industry Risks.” Covered Calls and Other Option Transactions. The Fund intends to provide current income from short-term gains earned through an option strategy which will normally consist of writing (selling) call options on equity securities in its portfolio (“covered calls”), but may, in amounts up to 15% of the Fund’s assets, consist of writing uncovered call options on additional amounts of such securities beyond the amounts held in its portfolio, on other securities not held in its portfolio and on indices comprised of Natural Resources Companies or Gold Companies or on exchange traded funds comprised of such issuers and also may consist of writing put options on securities of Natural Resources Companies or Gold Companies. Any premiums received by the Fund from writing options may result in short-term capital gains. Writing a covered call is the selling of an option contract entitling the buyer to purchase an underlying security that the Fund owns, while writing an uncovered call is the selling of such a contract entitling the buyer to purchase a security the Fund does not own or in an amount in excess of the amount the Fund owns. When the Fund sells a call option, it generates current income from short-term gains in the form of the premium paid by the buyer of the call option, but the Fund forgoes the opportunity to participate in any increase in the value of the underlying equity security above the exercise price 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 buyer 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 at that price. When the Fund sells a put option, it generates current income from short-term gains in the form of the premium paid by the buyer of the put option, but the Fund will have the obligation to buy the underlying security at the exercise price if the price of the security decreases below the exercise price of the option. If the Fund has written a call option, it may terminate its obligation by effecting a closing purchase transaction. This is accomplished by purchasing a call option with the same terms as the option previously written. However, 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. This is accomplished by selling an option with the same terms 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 it received from writing the option, or is more than the premium it 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 it received from writing the option, or is less than the premium it 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. Other principal factors affecting the market value of a put or a call option include supply and demand, 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 certain options transactions cannot serve as a complete hedge since the price movement of securities underlying certain options will not necessarily follow the price movements of the portfolio securities that may be subject to the hedge. An option position may be closed out only on an exchange that provides a secondary market for an option with the same terms or in a private transaction. Although the Fund will generally purchase or write options for which there appears to be an active secondary market, there is no assurance that a liquid secondary market on an exchange will exist for any particular option. In such event, it might not be possible to effect closing transactions in particular options, in which case 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. Although the Investment Adviser will attempt to take appropriate measures to minimize the risks relating to the Fund’s writing and purchasing of put and call options, there can be no assurance that the Fund will succeed in any option-writing program it undertakes. Uncovered Calls. The Fund may also write uncovered call options or put options. Foreign Securities. The Fund may invest in securities principally traded in securities markets outside the United States. Foreign investments may be affected favorably or unfavorably by changes in currency rates and in exchange control regulations. There may be less publicly available information about a foreign company than about a U.S. company, and foreign companies may not be subject to accounting, auditing and financial reporting standards and requirements comparable to those applicable to U.S. companies. Securities of some foreign companies may be less liquid or more volatile than securities of U.S. companies, and foreign brokerage commissions and custodian fees are generally higher than in the United States. Investments in foreign securities may also be subject to other risks different from those affecting U.S. investments, including local political or economic developments, expropriation or nationalization of assets and imposition of withholding taxes on dividend or interest payments. American Depositary Receipts. The Fund may invest in American Depositary Receipts (“ADRs”). Such investment may entail certain risks similar to foreign securities. ADRs are certificates representing an ownership interest in a security or a pool of securities issued by a foreign issuer and deposited with the depositary, typically a bank, and held in trust for the investor. The economies of many of the countries in which the issuer of a security underlying an ADR principally engages in business may not be as developed as the United States’ economy and may be subject to significantly different forces. Political or social instability, expropriation or confiscatory taxation, and limitations on the removal of funds or other assets could adversely affect the value of the Fund’s investments in such securities. The value of the securities underlying ADRs could fluctuate as exchange rates change between U.S. dollars and the currency of the country in which the foreign company is located. In addition, foreign companies are not registered with the SEC and are generally not subject to the regulatory controls imposed on United States issuers and, as a consequence, there is generally less publicly available information about foreign companies than is available about domestic companies. Foreign companies are not subject to uniform accounting, auditing and financial reporting standards, practices and requirements comparable to those applicable to domestic companies. Emerging Market Countries. The risks described above for foreign securities, including the risks of nationalization and expropriation of assets, are typically increased to the extent that the Fund invests in companies headquartered in developing, or emerging market, countries. Investments in securities of companies headquartered in such countries may be considered speculative and subject to certain special risks. The political and economic structures in many of these countries may be in their infancy and developing rapidly, and such countries may lack the social, political and economic characteristics of more developed countries. Certain of these countries have in the past failed to recognize private property rights and have at times nationalized and expropriated the assets of private companies. Some countries have inhibited the conversion of their currency to another. The currencies of certain emerging market countries have experienced devaluation relative to the U.S. dollar, and future devaluations may adversely affect the value of the Fund’s assets denominated in such currencies. Some emerging market countries have experienced substantial rates of inflation for many years. Continued inflation may adversely affect the economies and securities markets of such countries. In addition, unanticipated political or social developments may affect the value of the Fund’s investments in these countries and the availability of the Fund of additional investments in these countries. The small size, limited trading volume and relative inexperience of the securities markets in these countries may make the Fund’s investments in such countries illiquid and more volatile than investments in more developed countries, and the Fund may be required to establish special custodial or other arrangements before making investments in these countries. There may be little financial or accounting information available with respect to companies located in these countries, and it may be difficult as a result to assess the value or prospects of an investment in such companies. Restricted and Illiquid Securities. The Fund may invest in securities that are 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 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. Income Securities. 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 open-end funds that invest in those securities, which, in the absence of an applicable exemptive order, will not be affiliated with the Investment Adviser, and (ii) common 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 shareholders. 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. The Fund also may invest in common stock of issuers that have historically paid periodic dividends or otherwise made distributions to common shareholders. 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. Non-Investment Grade Securities. The Fund may invest up to 25% of its assets in securities rated below investment grade by recognized statistical rating agencies, such as convertible debt securities (which generally are rated lower than investment grade) and fixed-income securities that are rated lower than investment grade, or not rated but of similar quality as determined by the Investment Adviser. These securities, 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 by the financial press as “junk bonds” or “high yield” securities. Generally, such non-investment grade securities and unrated securities of comparable quality offer a higher current yield than is offered by higher rated securities, but also (i) will likely have some quality and protective characteristics that, in the judgment of the rating organizations, are outweighed by large uncertainties or major risk exposures to adverse conditions and (ii) are predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal in accordance with the terms of the obligation. The market values of certain of these securities also tend to be more sensitive to individual corporate developments and changes in economic conditions than higher quality securities. In addition, such non-investment grade securities and comparable unrated securities generally present a higher degree of credit risk. The risk of loss due to default by these issuers is significantly greater because such non-investment grade securities and unrated securities of comparable quality generally are unsecured and frequently are subordinated to the prior payment of senior indebtedness. In light of these risks, the Investment Adviser, in evaluating the creditworthiness of an issue, whether rated or unrated, will take various factors into consideration, which may include, as applicable, the issuer’s operating history, financial resources and its sensitivity to economic conditions and trends, the market support for the facility financed by the issue, the perceived ability and integrity of the issuer’s management and regulatory matters. In addition, the market value of securities in non-investment grade categories is more volatile than that of higher quality securities, and the markets in which such lower grade 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. 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. Interest rates have risen in recent months, and the risk that they may continue to do so is pronounced. 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 begun an aggressive 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, the Fund may invest not more than 5% of the total assets of the Fund in securities of issuers in default. The Fund will make an investment in securities of issuers in default only when the Investment Adviser believes that such issuers will honor their obligations or emerge from bankruptcy protection and the value of these securities will appreciate. By investing in securities of issuers in default, the Fund bears the risk that these issuers will not continue to honor their obligations or emerge from bankruptcy protection or that the value of the securities will not 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 value of such securities as well as the ability of certain issuers of such securities to repay principal and pay interest thereon or to refinance such securities. The market for those securities could react in a similar fashion in the event of any future economic recession. Temporary Defensive Investments. 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 all or a portion of 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 certain fundamental investment restrictions and 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 its investment objectives during temporary defensive periods. 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. 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 as a form of hedging to offset potential declines in long positions in the same or similar securities, including short sales of securities in the Fund’s portfolio at the time of sale (shorting “against the box”). The short sale of a security is considered a speculative investment technique. At the time of the sale, the Fund will own, or have the immediate and unconditional right to acquire at no additional cost, identical or similar securities or establish a hedge against a security of the same issuer which may involve additional cost, such as an “in the money” warrant. Short sales “against the box” are subject to special tax rules, one of the effects of which may be to accelerate the recognition of income by the Fund. Other than with respect to short sales against the box, the Fund will limit short sales of securities to not more than 5% of the Fund’s assets. When the Fund makes a short sale, it must deliver the security 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. 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). Although the Fund’s gain is limited to the price at which it sold the security short, its potential loss is theoretically unlimited. 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, 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. Registered Investment Companies. The Fund may invest in registered investment companies in accordance with the 1940 Act to the extent consistent with the Fund’s investment objectives, including exchange traded funds that concentrate in investments in securities of companies in the natural resources or gold industries. The 1940 Act generally prohibits the Fund from investing more than 5% of its assets in any one other investment company or more than 10% of its assets in all other investment companies. However, many exchange-traded funds are exempt from these limitations. Investment Restrictions. The Fund has adopted certain investment restrictions as fundamental policies of the Fund. Under the 1940 Act, a fundamental policy may not be changed without the vote of a majority, as defined in the 1940 Act, of the outstanding voting securities of the Fund (voting together as a single class subject to class approval rights of any preferred shares). Portfolio Turnover. The Fund will buy and sell securities to accomplish its investment objectives. The investment policies of the Fund, including its strategy of writing covered call options on securities in its portfolio, may lead to frequent changes in investments, particularly in periods of rapidly fluctuating interest or currency exchange rates, and are expected to result in portfolio turnover that is higher than that of many investment companies, may initially be higher than 100% and may result in the Fund paying higher commissions than many investment companies. Portfolio turnover generally involves some 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 rate for the fiscal years ended December 31, 2021 and 2022 was 109% and 121%, respectively. Leverage 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) so long as its 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. Any such preferred shares may be convertible in accordance with the SEC staff guidelines, which may permit the Fund to obtain leverage at attractive rates. 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—Special Risks to Holders of Common Shares—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. 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 agreement 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. 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. Options. The Fund may, from time to time, subject to guidelines of the Board and the limitations set forth this Annual Report, 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 gives the holder of the option the right to buy from the writer of the call option, in return for a premium, 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 a contract that gives the holder of the option the right, in return for a premium, to sell to the seller the underlying security at a specified price. The seller of the put option has the obligation to buy the underlying security upon exercise at the exercise price. 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 call option is “uncovered” if the underlying security covered by the call is not held by the Fund. 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. 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, 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. 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, 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 correctly predict 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 that 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 exist for any particular option. In such event it might not be possible to effect closing transactions in particular options, in which case 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. 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. Options on Securities Indices. The Fund may purchase and sell securities index options. One effect of such transactions may be to hedge all or part of the Fund’s securities holdings against a general decline in the securities market or a segment of the securities market. Options on securities indices are similar to options on stocks except that, rather than the right to take or make delivery of stock at a specified price, an option on a securities index gives the holder the right to receive, upon exercise of the option, an amount of cash if the closing level of the securities index upon which the option is based is greater than, in the case of a call option, or less than, in the case of a put option, the exercise price of the option. The Fund’s successful use of options on indices depends upon its ability to predict the direction of the market and is subject to various additional risks. The correlation between movements in the index and the price of the securities being hedged against is imperfect and the risk from imperfect correlation increases as the composition of the Fund diverges from the composition of the relevant index. Accordingly, a decrease in the value of the securities being hedged against may not be wholly offset by a gain on the exercise or sale of a securities index put option held by the Fund. Futures Contracts and Options on Futures. The Fund may enter into futures contracts or options on futures contracts. It is anticipated that these investments, if any, will be made by the Fund primarily for the purpose of hedging against changes in the value of its portfolio securities and in the value of securities it intends to purchase. Such investments will only be made if they are economically appropriate to the reduction of risks involved in the management of the Fund. In this regard, the Fund may enter into futures contracts or options on futures for the purchase or sale of securities indices or other financial instruments including, but not limited to, U.S. government securities. A “sale” of a futures contract (or a “short” futures position) means the assumption of a contractual obligation to deliver the securities underlying the contract at a specified price at a specified future time. A “purchase” of a futures contract (or a “long” futures position) means the assumption of a contractual obligation to acquire the securities underlying the contract at a specified price at a specified future time. Certain futures contracts, including stock and bond index futures, are settled on a net cash payment basis rather than by the sale and delivery of the securities underlying the futures contracts. No consideration will be paid or received by the Fund upon the purchase or sale of a futures contract. Initially, the Fund will be required to deposit with the broker an amount of cash or cash equivalents equal to approximately 1% to 10% of the contract amount (this amount is subject to change by the exchange or board of trade on which the contract is traded and brokers or members of such board of trade may charge a higher amount). This amount is known as the “initial margin” and is in the nature of a performance bond or good faith deposit on the contract. Subsequent payments, known as “variation margin,” to and from the broker will be made daily as the price of the index or security underlying the futures contract fluctuates. At any time prior to the expiration of the futures contract, the Fund may elect to close the position by taking an opposite position, which will operate to terminate its existing position in the contract. An option on a futures contract gives the purchaser the right, in return for the premium paid, to assume a position in a futures contract at a specified exercise price at any time prior to the expiration of the option. Upon exercise of an option, the delivery of the futures position by the writer of the option to the holder of the option will be accompanied by delivery of the accumulated balance in the writer’s futures margin account attributable to that contract, which represents the amount by which the market price of the futures contract exceeds, in the case of a call, or is less than, in the case of a put, the exercise price of the option on the futures contract. The potential loss related to the purchase of an option on futures contracts is limited to the premium paid for the option (plus transaction costs). Because the value of the option purchased is fixed at the point of sale, there are no daily cash payments by the purchaser to reflect changes in the value of the underlying contract; however, the value of the option does change daily and that change would be reflected in the net assets of the Fund. 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. Limitations on the Purchase and Sale of Futures Contracts, Certain Options, and Swaps. Subject 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. Swaps. The Fund may enter into total rate of return, credit default or other types of swaps and related derivatives for the purpose of 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 for the purpose of increasing the income of the Fund. 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. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
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: General Risks 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 income producing securities. Recently, central banks such as the Federal Reserve Bank have been raising interest rates to combat the rate of inflation. 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. Additional interest rate increases in the future could cause the value of the Fund’s assets to decrease. In addition, inflation has recently reached its highest levels in decades. As such, the markets for income producing securities may experience heightened levels of interest rate, volatility and liquidity risk. 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. Interest rates have risen over the past year and the chance that they will continue to rise is pronounced. 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. Recently, central banks such as the Federal Reserve Bank have been increasing interest rates in an effort to slow the rate of inflation. There is a risk that increased 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. Recently, inflation has increased to its highest level in decades, and the Federal Reserve has been raising the federal funds rate in response. 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. Total Return Risk. The Fund utilizes several investment management techniques in an effort to generate positive total return. The risks of these techniques, such as option writing, leverage, concentration in certain industries, and investing in emerging markets, are described in the following paragraphs. Taken together these and other techniques represent a risk that the Fund will experience a negative total return even in market environments that are generally positive and that the Fund’s returns, both positive and negative, may be more volatile than if the Fund did not utilize these investment techniques. Industry Risk. The Fund’s investments will be concentrated in the natural resources and gold industries. Because the Fund is concentrated in these industries, it may present more risks than if it were broadly diversified over numerous industries and sectors of the economy. A downturn in the natural resources or gold industries would have a larger impact on the Fund than on an investment company that does not concentrate in such industries. The Fund invests in equity securities of Natural Resources Companies. A downturn in the indicated natural resources industries would have a larger impact on the Fund than on an investment company that does not invest significantly in such industries. Such industries can be significantly affected by the supply of and demand for the indicated commodities and related services, exploration and production spending, government regulations, world events and economic conditions. For example, the COVID-19 pandemic drastically reduced the demand for various natural resources, including oil, and drastically increased the price volatility of natural resources and companies within the natural resources industry. A new or extended period of reduced (or negative) prices may significantly lengthen the time that companies within the natural resources industries would need to recover after a stabilization of prices. The metals (including both precious metals—such as silver and platinum—and base (i.e., non-precious) metals—such as copper, lead, nickel and zinc), paper, food and agriculture, forestry products, water, gas, oil, sustainable energy and other commodities industries can be significantly affected by events relating to international political developments, the success of exploration projects, commodity prices, and tax and government regulations. The stock prices of Natural Resources Companies, some of which prior to the COVID-19 pandemic had experienced substantial price increases, may also experience greater price volatility than other types of common stocks. The impact of COVID-19 on securities issued by Natural Resources Companies was dramatic beginning in February 2020 and ultimately culminating in near-panic selling though the middle of March 2020. Securities issued by Natural Resources Companies are sensitive to changes in the prices of, and in supply and demand for, the indicated commodities. The value of securities issued by Natural Resources Companies may be affected by changes in overall market movements, changes in interest rates, or factors affecting a particular industry or commodity, such as weather, embargoes, tariffs, policies of commodity cartels and international economic, political and regulatory developments. The Investment Adviser’s judgments about trends in the prices of these securities and commodities may prove to be incorrect. It is possible that the performance of securities of Natural Resources Companies may lag the performance of other industries or the broader market as a whole. The Fund also invests in equity securities of Gold Companies. Equity securities of Gold Companies may experience greater volatility than companies not involved in the gold industry. Investments related to gold are considered speculative and are affected by a variety of worldwide economic, financial and political factors. The price of gold may fluctuate sharply, which has experienced substantial increases since August, 2020, but which also may be subject to substantial decreases, over short periods of time due to changes in inflation or expectations regarding inflation in various countries, the availability of supplies of gold, changes in industrial and commercial demand, gold sales by governments, central banks or international agencies, investment speculation, monetary and other economic policies of various governments and government restrictions on private ownership of gold. In times of significant inflation or great economic uncertainty, Gold Companies have at times outperformed securities markets generally. However, in times of stable economic growth, traditional equity and debt investments could offer greater appreciation potential and the value of gold and the prices of equity securities of Gold Companies may be adversely affected, which could in turn affect the Fund’s returns. Some Gold Companies hedge, to varying degrees, their exposure to declines in the price of gold. Such hedging limits a Gold Company’s ability to benefit from future rises in the price of gold. The Investment Adviser’s judgments about trends in the prices of securities of Gold Companies may prove to be incorrect. It is possible that the performance of securities of Gold Companies may lag the performance of other industries or the broader market as a whole. Supply and Demand Risk. A decrease in the production of or exploration of, gold, metals (including both precious metals—such as silver and platinum—and base (i.e., non-precious) metals—such as copper, lead, nickel and zinc), paper, food and agriculture, forestry products, gas, oil and other commodities or a decrease in the volume of such commodities available for transportation, mining, processing, storage or distribution may adversely impact the financial performance of the Fund’s investments. Production declines and volume decreases could be caused by various factors, including catastrophic events affecting production, depletion of resources, labor difficulties, environmental proceedings, increased regulations, equipment failures and unexpected maintenance problems, import supply disruption, increased competition from alternative energy sources or commodity prices. For example, the COVID-19 pandemic increased price and demand volatility for various natural resources, including oil, and companies within the natural resources industry, as demand drastically reduced at the height of the pandemic and significantly increased as the pandemic subsided. A similar or renewed and extended period of price and demand volatility, including reduced (or negative) prices, may significantly lengthen the time that companies within the natural resources industries would need to recover after a stabilization of prices. Such volatility may be further magnified by the 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. Future declines in demand for the indicated commodities could also adversely affect the financial performance of Natural Resources Companies and Gold Companies over the long term. Factors which could lead to a decline in demand include economic recession or other adverse economic conditions, higher fuel taxes or governmental regulations, increases in fuel economy, consumer shifts to the use of alternative fuel sources, changes in commodity prices, or weather. Depletion and Exploration Risk. Many Natural Resources Companies and Gold Companies are either engaged in the production or exploration of particular commodities or are engaged in transporting, storing, distributing and processing such commodities. To maintain or increase their revenue level, these companies or their customers need to maintain or expand their reserves through exploration of new sources of supply, the development of existing sources, acquisitions, or long-term contracts to acquire reserves. The financial performance of Natural Resources Companies and Gold Companies may be adversely affected if they, or the companies to whom they provide products or services, are unable to cost effectively acquire additional products or reserves sufficient to replace the natural decline. Regulatory Risk. Natural Resources Companies and Gold Companies may be subject to extensive government regulation in virtually every aspect of their operations, including how facilities are constructed, maintained and operated, environmental and safety controls, and in some cases the prices they may charge for the products and services they provide. Various governmental authorities have the power to enforce compliance with these regulations and the permits issued under them, and violators are subject to administrative, civil and criminal penalties, including civil fines, injunctions or both. Stricter laws, regulations or enforcement policies could be enacted in the future, which would likely increase compliance costs and may adversely affect the financial performance of Natural Resources Companies and Gold Companies. Commodity Pricing Risk. The operations and financial performance of Natural Resources Companies and Gold Companies may be directly affected by the prices of the indicated commodities, especially those Natural Resources Companies and Gold Companies for whom the commodities they own are significant assets. Commodity prices fluctuate for several reasons, including changes in market and economic conditions, levels of domestic production, impact of governmental regulation and taxation, the availability of transportation systems and, in the case of oil and gas companies in particular, conservation measures and the impact of weather. Volatility of commodity prices, which may lead to a reduction in production or supply, may also negatively affect the performance of Natural Resources Companies and Gold Companies which are solely involved in the transportation, processing, storing, distribution or marketing of commodities. Volatility of commodity prices may also make it more difficult for Natural Resources Companies and Gold Companies to raise capital to the extent the market perceives that their performance may be directly or indirectly tied to commodity prices. Catastrophe Risk. The operations of Natural Resources Companies and Gold Companies are subject to many hazards inherent in the development of energy infrastructure and the acquisition, exploration, production, mining, processing (including fractionating), refining, transportation (including trans-loading), storage, servicing or marketing of natural resources, including, but not limited to, crude oil, refined products, petrochemicals, natural gas, natural gas liquids, coal, metals and renewable energy sources, including damage to production equipment, pipelines, storage tanks or related equipment and surrounding properties caused by hurricanes, tornadoes, floods, fires and other natural disasters or by acts of terrorism; inadvertent damage from construction or other equipment; leaks of natural gas, natural gas liquids, crude oil, refined petroleum products or other hydrocarbons; and fires and explosions. These risks could result in substantial losses due to personal injury or loss of life, severe damage to and destruction of property and equipment and pollution or other environmental damage, and might result in the curtailment or suspension of their related operations. Not all Natural Resources Companies or Gold Companies are fully insured against all risks inherent to their businesses. If a significant accident or event occurs that is not fully insured, it could adversely affect a Natural Resources Company’s or Gold Company’s operations and financial condition. Recently, there have been physical and cyber terrorist attacks on natural gas and oil pipelines, resulting in significant destruction to critical property and equipment, supply disruption and the curtailment and suspension of certain Natural Resources Companies activities. Climate Change Risk. Climate change, and regulations intended to control its impact, may affect the value of the Fund’s investments. The Fund’s current evaluation is that the near-term effects of climate change and climate change regulation on the Fund’s investments are not material, but the Fund cannot predict the long-term impacts on the Fund or its investments from climate change or related regulations. The Fund is subject to the special risks associated with climate change. Weather may play a role in the cash flows of the Natural Resources Companies in which the Fund invests. Although many of the companies in this sector can reasonably predict seasonal weather patterns, extreme weather conditions, such as those that may result from climate change, many be unpredictable. The damage done by extreme weather could adversely affect the financial condition of such companies. Additionally, new or strengthened regulations or legislation could increase the operating costs and/or decrease the revenues of Natural Resources Companies. Interest Rate Risk for Natural Resources Companies and Gold Companies. The prices of the equity and debt securities of the Natural Resources Companies and Gold Companies that the Fund holds in its portfolio are susceptible in the short term to decline when interest rates rise. Rising interest rates could limit the capital appreciation of securities of certain investments because of the increased availability of alternative investments with yields comparable to those investments. Rising interest rates could adversely affect the financial performance of Natural Resources Companies and Gold Companies generally by increasing their cost of capital. This may reduce their ability to execute acquisitions or expansion projects in a cost-effective manner. Interest rates have risen in recent months, and the risk that they may continue to do so is pronounced. Cyber and Physical Security Risks. Natural Resources Companies 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 countries continue to investigate the incident, but several, including Sweden, have concluded the explosions were caused by grievous sabotage. Risks Associated with Covered Calls and Other Option Transactions. There are several risks associated with transactions in options on securities. For example, there are significant differences between the securities and options markets that could result in an imperfect correlation between these markets, causing a given covered call option transaction not to achieve its objectives. A decision as to whether, when and how to use covered calls (or other options) involves the exercise of skill and judgment, and even a well-conceived transaction may be unsuccessful because of market behavior or unexpected events. The use of options may require the Fund to sell portfolio securities at inopportune times or for prices other than current market values, may limit the amount of appreciation the Fund can realize on an investment, or may cause the Fund to hold a security it might otherwise sell. As the writer of a covered call option, the Fund forgoes, during the option’s life, the opportunity to profit from increases in the market value of the security covering the call option above the exercise price of the call option, but has retained the risk of loss should the price of the underlying security decline. Although such loss would be offset in part by the option premium received, in a situation in which the price of a particular stock on which the Fund has written a covered call option declines rapidly and materially or in which prices in general on all or a substantial portion of the stocks on which the Fund has written covered call options decline rapidly and materially, the Fund could sustain material depreciation or loss in its net assets to the extent it does not sell the underlying securities (which may require it to terminate, offset or otherwise cover its option position as well). The writer of an option has no control over the time when it may be required to fulfill its obligation as a writer of the option. Once an option writer has received an exercise notice, it cannot effect a closing purchase transaction in order to terminate its obligation under the option and must deliver the underlying security at the exercise price. There can be no assurance that a liquid market will exist when the Fund seeks to close out an option position. Reasons for the absence of a liquid secondary market for exchange-traded options include the following: (i) there may be insufficient trading interest; (ii) restrictions may be imposed by an exchange on opening transactions or closing transactions or both; (iii) trading halts, suspensions or other restrictions may be imposed with respect to particular classes or series of options; (iv) unusual or unforeseen circumstances may interrupt normal operations on an exchange; (v) the trading facilities of an exchange or the Options Clearing Corporation (the “OCC”) may not be adequate to handle current trading volume; or (vi) the relevant exchange could, for economic or other reasons, decide or be compelled at some future date to discontinue the trading of options (or a particular class or series of options). If trading were discontinued, the secondary market on that exchange (or in that class or series of options) would cease to exist. However, outstanding options on that exchange that had been issued by the OCC as a result of trades on that exchange would continue to be exercisable in accordance with their terms. The Fund’s ability to terminate OTC options may be more limited than with exchange-traded options and may involve the risk that counterparties participating in such transactions will not fulfill their obligations. If the Fund were unable to close out a covered call option that it had written on a security, it would not be able to sell the underlying security unless the option expired without exercise. The hours of trading for options may not conform to the hours during which the underlying securities are traded. To the extent that the options markets close before the markets for the underlying securities, significant price and rate movements can take place in the underlying markets that cannot be reflected in the options markets. Call options are marked to market daily and their value will be affected by changes in the value of and dividend rates of the underlying common stocks, an increase in interest rates, changes in the actual or perceived volatility of the stock market and the underlying common stocks and the remaining time to the options’ expiration. Additionally, the exercise price of an option may be adjusted downward before the option’s expiration as a result of the occurrence of certain corporate events affecting the underlying equity security, such as extraordinary dividends, stock splits, merger or other extraordinary distributions or events. A reduction in the exercise price of an option would reduce the Fund’s capital appreciation potential on the underlying security. Limitation on Covered Call Writing Risk. The number of covered call options the Fund can write is limited by the number of shares of the corresponding common stock the Fund holds. Furthermore, the Fund’s covered call options and other options transactions will be subject to limitations established by each of the exchanges, boards of trade or other trading facilities on which such options are traded. These limitations govern the maximum number of options in each class which may be written or purchased by a single investor or group of investors acting in concert, regardless of whether the options are written or purchased on the same or different exchanges, boards of trade or other trading facilities or are held or written in one or more accounts or through one or more brokers. As a result, the number of covered call options that the Fund may write or purchase may be affected by options written or purchased by it and other investment advisory clients of the Investment Adviser. An exchange, board of trade or other trading facility may order the liquidation of positions found to be in excess of these limits, and it may impose certain other sanctions. Risks Associated with Uncovered Calls. There are special risks associated with uncovered option writing which expose the Fund to potentially significant loss. As the writer of an uncovered call option, the Fund has no risk of loss should the price of the underlying security decline, but bears unlimited risk of loss should the price of the underlying security increase above the exercise price until the Fund covers its exposure. As with writing uncovered calls, the risk of writing uncovered put options is substantial. The writer of an uncovered put option bears a risk of loss if the value of the underlying instrument declines below the exercise price. Such loss could be substantial if there is a significant decline in the value of the underlying instrument. For combination writing, where the Fund writes both a put and a call on the same underlying instrument, the potential risk is unlimited. If a secondary market in options were to become unavailable, the Fund could not engage in losing transactions and would remain obligated until expiration or assignment. 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 amount 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 will invest 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. Distribution Risk for Equity Income Portfolio 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 or other distributions, however, does not guarantee that the issuer will continue to pay dividends or other distributions 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, an issuer 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. 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 div-idends 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 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.
Foreign Securities Risk. Because many of the world’s Natural Resources Companies and Gold Companies are located outside of the United States, the Fund may have a significant portion of its investments in securities that are traded in foreign markets and that are not subject to the requirements of the U.S. securities laws, markets and accounting requirements (“Foreign Securities”). 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. The governments of certain countries may prohibit or impose substantial restrictions on foreign investments in their capital markets or in certain industries, and there may be greater levels of price volatility in foreign markets. 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, and it may be difficult to effect repatriation of capital invested in certain countries. 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. The 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 publicly 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. Non-U.S. markets also have different clearance and settlement procedures which in some markets have at times failed to keep pace with the volume of transactions, thereby creating substantial delays and settlement failures that could adversely affect the Fund’s performance. 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 sponsored 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 objectives 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. Emerging Markets Risk. The considerations noted above in “Foreign Securities Risk” are generally intensified for investments in emerging market countries. Emerging market countries typically have economic and political systems that are less fully developed, and can be expected to be less stable than those of more developed countries. Investing in securities of companies in emerging markets may entail special risks relating to potential political and economic instability and the risks of expropriation, nationalization, confiscation or the imposition of restrictions on foreign investment, the lack of hedging instruments and restrictions on repatriation of capital invested. Economies of such countries can be subject to rapid and unpredictable rates of inflation or deflation. Emerging securities markets are substantially smaller, less developed, less liquid and more volatile than the major securities markets. The limited size of emerging securities markets and limited trading volume compared to the volume of trading in U.S. securities could cause prices to be erratic for reasons apart from factors that affect the quality of the securities. For example, limited market size may cause prices to be unduly influenced by traders who control large positions. Adverse publicity and investors’ perceptions, whether or not based on fundamental analysis, may decrease the value and liquidity of portfolio securities, especially in these markets. Other risks include high concentration of market capitalization and trading volume in a small number of issuers representing a limited number of industries, as well as a high concentration of investors and financial intermediaries; overdependence on exports, including gold and natural resources exports, making these economies vulnerable to changes in commodity prices; overburdened infrastructure and obsolete or unseasoned financial systems; environmental problems; less developed legal systems; and less reliable securities custodial services and settlement practices. Certain emerging markets may also face other significant internal or external risks, including the risk of war and civil unrest. For all of these reasons, investments in emerging markets may be considered speculative. 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 the Fund. 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 have adversely affected the value and exchange rate of the euro and pound sterling, and 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. Income Risk. The income shareholders receive from the Fund is expected to be based primarily on income from short-term gains that the Fund earns from its investment strategy of writing covered calls and dividends and other distributions received from its investments. If the Fund’s covered call strategy fails to generate sufficient income from short-term gains or the distribution rates or yields of the Fund’s holdings decrease, shareholders’ income from the Fund could decline. Non-Investment Grade Securities. The Fund may invest in below investment-grade securities, also known as “high-yield” securities or “junk bonds.” These securities, 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 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 market value of securities in lower grade categories is more volatile than that of higher quality securities, and the markets in which such lower grade 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. 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 issues 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. Interest Rate Risk for Fixed Income Securities. The primary risk associated with fixed income securities is interest rate risk. A decrease in interest rates will generally result in an increase in the value of a fixed income security, while increases in interest rates will generally result in a decline in its value. This effect is generally more pronounced for fixed rate securities than for securities whose income rate is periodically reset. Interest rates have risen in recent months, and the risk that they may continue to do so is pronounced. See “—General Risks—Interest Rate Risks Generally.” Further, while longer term fixed rate securities may pay higher interest rates than shorter term securities, longer term fixed rate securities, like fixed rate securities, also tend to be more sensitive to interest rate changes and, accordingly, tend to experience larger changes in value as a result of interest rate changes. An increase in market interest rates will also generally result in a decrease in the price of any of the Fund’s outstanding preferred shares. 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. Repeat occurrences of similar events 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. Special Risks Related to Investment in Derivatives. The Fund may participate in derivative transactions. Such transactions entail certain execution, market, liquidity, hedging and tax risks. Participation in the options or futures markets, in currency exchange transactions and in other 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, foreign currency, interest rate 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 options, foreign currency, futures contracts and options on futures contracts, securities indices and foreign currencies 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 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 comply with Rule 18f-4; and
| ● | the creditworthiness of counterparties.
Options, futures contracts, swaps contracts, and options thereon and forward contracts on securities and currencies may be traded on foreign exchanges. Such transactions may not be regulated as effectively as similar transactions in the United States, may not involve a clearing mechanism and related guarantees, and are subject to the risk of governmental actions affecting trading in, or the prices of, foreign securities. The value of such positions also could be adversely affected by (i) other complex foreign political, legal and economic factors, (ii) lesser availability than in the United States of data on which to make trading decisions, (iii) delays in the ability of the Fund to act upon economic events occurring in the foreign markets during non-business hours in the United States, (iv) the imposition of different exercise and settlement terms and procedures and margin requirements than in the United States and (v) less trading volume. Exchanges on which options, futures, swaps and options on futures or swaps are traded may impose limits on the positions that the Fund may take in certain circumstances. 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. Exchange-traded derivatives and OTC derivative transactions submitted for clearing through a central counterparty have become subject to minimum initial and variation margin requirements set by the relevant clearinghouse, as well as possible margin requirements mandated by the SEC or the CFTC. These regulators also have broad discretion to impose margin requirements on non-cleared OTC derivatives. These margin requirements will increase the overall costs for the Fund. While hedging transactions can reduce or eliminate losses, they can also reduce or eliminate gains. Hedges are sometimes subject to imperfect matching between the derivative and the underlying instrument, and there can be no assurance that the Fund’s hedging transactions will be effective. Derivatives may also 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 and options contracts, a clearing organization may use assets of a non-defaulting customer held in an omnibus account at the clearing organization to satisfy payment obligations of a defaulting customer of the clearing member to the clearing organization. As a result, in the event of a default or the clearing broker’s other clients or the clearing broker’s failure to extend own funds in connection with any such default, the Fund would not be able to recover the full amount of assets deposited by the clearing broker on its behalf with the clearing organization. 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 obligations under a swap agreement will be accrued daily (offset against any amounts owing to the Fund) and any accrued but unpaid net amounts owed to a swap counterparty will be covered by the maintenance of liquid assets in accordance with SEC staff positions on the subject. 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. 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. 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 may use financial leverage for investment purposes. A leveraged capital structure would create special risks not associated with unleveraged funds that have a similar investment objectives 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 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 preferred shares or notes 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 Holders of Common Shares—Leverage Risk.” Market Discount Risk. The Fund is a non-diversified, closed-end management investment company. 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 long-term growth of capital. 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 objectives as well as the shareholder’s other investments when considering an investment in the Fund. Portfolio Turnover Risk. The investment policies of the Fund, including its strategy of writing covered call options on securities in its portfolio, may result in portfolio turnover that is higher than that of many investment companies. Increased portfolio turnover rates will result in higher costs from brokerage commissions, dealer-mark-ups and other transaction costs and may also may decrease the after-tax return to individual investors in the Fund to the extent it results in a decrease in the portion of the Fund’s distributions that is attributable to long-term capital gain. 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. Non-Diversified Status. The Fund is classified as a “non-diversified” investment company under the 1940 Act, which means the Fund is not limited by the 1940 Act in the proportion of its assets that may be invested in the securities of a single issuer. As a non-diversified investment company, the Fund may invest in the securities of individual issuers to a greater degree than a diversified investment company. As a result, the Fund may be more vulnerable to events affecting a single issuer and therefore, subject to greater volatility than a fund that is more broadly diversified. Accordingly, an investment in the Fund may present greater risk to an investor than an investment in a diversified company. 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 Fund is dependent upon the expertise of Vincent Hugonnard-Roche as the sole option strategist on the Fund’s portfolio management team. If the Fund were to lose the services of Mr. Roche, it could be temporarily adversely affected until a suitable replacement could be found. 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 (such as COVID-19), 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 on 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. 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, on August 16, 2022, 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, including in respect of investment company names and other matters, 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(s). 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 NAV; violations of applicable privacy and other laws; regulatory fines, penalties, reputational damage, reimbursement or other compensation costs; and/ or additional compliance costs. The Fund may incur additional costs for cyber security risk management and remediation purposes. In addition, cyber security risks may also impact issuers of securities in which the Fund invests, which may cause the Fund’s investment in such issuers to lose value. There 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. 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. Restricted and Illiquid Securities Risk. 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 a security is valued for determining the Fund’s net asset value and the price the Fund actually receives upon sale. Investment Companies. The Fund may invest in the securities of other investment companies, including exchange traded funds, to the extent permitted by law. To the extent the Fund invests in the common equity of investment companies, the Fund will bear its ratable share of any such investment company’s expenses, including management fees. The Fund will also remain obligated to pay management fees to the Investment Adviser with respect to the assets invested in the securities of other investment companies. In these circumstances holders of the Fund’s common shares will be in effect subject to duplicative investment expenses. 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 Declaration of Trust authorizes it to issue an unlimited number of shares. The Board may make certain amendments to the 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. Legal, Tax and Regulatory Risks. Legal, tax and regulatory changes could occur that may have material adverse effects on the Fund. 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. 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, 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. 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 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 of the aggregate net asset value of their common shares. Such dilution 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, 2022, the amount of leverage represented approximately 21% 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 preferred shares or notes 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, 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. 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 annual rate of 1.00% 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 and do not reduce the principal due to noteholders on maturity or the liquidation preference to which preferred shareholders are entitled. 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 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, 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 21% of the Fund’s total net assets (the Fund’s amount of outstanding financial leverage as of December 31, 2022), and (2) charge interest or involve dividend payments at a projected blended annual average leverage dividend or interest rate of 5.20%, then the total return generated by the Fund’s portfolio (net of estimated expenses) must exceed approximately 1.16% 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 table 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 21% of the Fund’s net assets (the Fund’s outstanding financial leverage as of December 31, 2022), the Fund’s current projected blended annual average leverage dividend or interest rate of 5.20% (the average dividend rate on the Fund’s outstanding financial leverage as of December 31, 2022), a base management fee at an annual rate of 1.00% and estimated annual incremental expenses attributable to any outstanding preferred shares of approximately 0.06% 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 |  |  | (14.42 | )% |  |  | (8.06 | )% |  |  | (1.70 | )% |  |  | 4.66 | % |  |  | 11.02 | %
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 Risks to Holders of 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 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 its 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 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 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 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. For the fiscal year ended December 31, 2022, the Fund made distributions of $0.36 per common share, approximately $0.336 per common share which constituted a 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; 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. In order to obtain and maintain attractive credit quality ratings for preferred shares or notes, if desired, the Fund’s portfolio must satisfy over-collateralization tests established by the relevant rating agencies. These tests are more difficult to satisfy to the extent the Fund’s portfolio securities are of lower credit quality, longer maturity or not diversified by issuer and industry. These guidelines could affect portfolio decisions and may be more stringent than those imposed by the 1940 Act. A rating (if any) by a rating 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 (if any) does not address 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 notes or preferred shares, we may alter our portfolio or redeem the preferred securities or notes under certain circumstances. 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] | 6. 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 in 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, 2022 and December 31, 2021 the Fund repurchased and retired 904,871 and 872,702 shares, respectively, of its common shares at an investment of $4,543,193 and $4,517,773, respectively, and an average discount of approximately 14.36% and 13.06%, respectively, from its NAV. Transactions in common shares of beneficial interest for the years ended December 31, 2022 and 2021, respectively were as follows:
|  | Year Ended December 31, 2022 |  |  | Year Ended December 31, 2021 |
|  | Shares |  |  | Amount |  |  | Shares |  |  | Amount |
Net decrease from repurchase of common shares |  |  | (904,871 | ) |  | $ | (4,543,193 | ) |  |  | (872,702 | ) |  | $ | (4,517,773 | )
The Fund has an effective shelf registration authorizing the issuance of $200 million in common or preferred shares. The Fund’s Declaration of Trust, as amended, authorizes the issuance of an unlimited number of $0.001 par value Preferred Shares. On October 26, 2017, the Fund issued 1,200,000 shares of 5.200% Series A Cumulative Preferred Shares (Series A Preferred), receiving $28,851,132, after the deduction of offering expenses of $203,868 and underwriting fees of $945,000. The Series A Preferred has a liquidation value of $25 per share and an annual dividend rate of 5.20%. The Board has authorized the repurchase of the Series A Preferred in the open market at prices less than $25 liquidation value per share. The Fund did not repurchase any Series A Preferred Shares in 2021. During the year ended December 31, 2022 the Fund repurchased and retired 2,139 Series A Preferred an investment of $50,082 and at an average discount of approximately 6.39% to its liquidation preference. At December 31, 2022, 1,167,963 shares were outstanding and accrued dividends amounted to $21,088. The Series A Preferred is senior to the common shares and results 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 Preferred are cumulative. The Fund is required by the 1940 Act and by the Statement of Preferences to meet certain asset coverage tests with respect to the Series A Preferred. 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 Preferred at the redemption price of $25 per share plus an amount equal to the accumulated and unpaid dividends whether or not declared on such shares in order to meet the 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 rate, which could have either a beneficial or detrimental impact on net investment income and gains available to common shareholders. The holders of Preferred Shares generally are entitled to one vote per share held on each matter submitted to a vote of shareholders of the Fund and will vote together with holders of common shares 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 Shares, and the approval of two-thirds of each class, voting separately, of the Fund’s outstanding voting shares 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. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

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 income producing securities. Recently, central banks such as the Federal Reserve Bank have been raising interest rates to combat the rate of inflation. 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. Additional interest rate increases in the future could cause the value of the Fund’s assets to decrease. In addition, inflation has recently reached its highest levels in decades. As such, the markets for income producing securities may experience heightened levels of interest rate, volatility and liquidity risk. 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. Interest rates have risen over the past year and the chance that they will continue to rise is pronounced. 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. Recently, central banks such as the Federal Reserve Bank have been increasing interest rates in an effort to slow the rate of inflation. There is a risk that increased 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. Recently, inflation has increased to its highest level in decades, and the Federal Reserve has been raising the federal funds rate in response. 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] | Total Return Risk. The Fund utilizes several investment management techniques in an effort to generate positive total return. The risks of these techniques, such as option writing, leverage, concentration in certain industries, and investing in emerging markets, are described in the following paragraphs. Taken together these and other techniques represent a risk that the Fund will experience a negative total return even in market environments that are generally positive and that the Fund’s returns, both positive and negative, may be more volatile than if the Fund did not utilize these investment techniques. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] | Industry Risk. The Fund’s investments will be concentrated in the natural resources and gold industries. Because the Fund is concentrated in these industries, it may present more risks than if it were broadly diversified over numerous industries and sectors of the economy. A downturn in the natural resources or gold industries would have a larger impact on the Fund than on an investment company that does not concentrate in such industries. The Fund invests in equity securities of Natural Resources Companies. A downturn in the indicated natural resources industries would have a larger impact on the Fund than on an investment company that does not invest significantly in such industries. Such industries can be significantly affected by the supply of and demand for the indicated commodities and related services, exploration and production spending, government regulations, world events and economic conditions. For example, the COVID-19 pandemic drastically reduced the demand for various natural resources, including oil, and drastically increased the price volatility of natural resources and companies within the natural resources industry. A new or extended period of reduced (or negative) prices may significantly lengthen the time that companies within the natural resources industries would need to recover after a stabilization of prices. The metals (including both precious metals—such as silver and platinum—and base (i.e., non-precious) metals—such as copper, lead, nickel and zinc), paper, food and agriculture, forestry products, water, gas, oil, sustainable energy and other commodities industries can be significantly affected by events relating to international political developments, the success of exploration projects, commodity prices, and tax and government regulations. The stock prices of Natural Resources Companies, some of which prior to the COVID-19 pandemic had experienced substantial price increases, may also experience greater price volatility than other types of common stocks. The impact of COVID-19 on securities issued by Natural Resources Companies was dramatic beginning in February 2020 and ultimately culminating in near-panic selling though the middle of March 2020. Securities issued by Natural Resources Companies are sensitive to changes in the prices of, and in supply and demand for, the indicated commodities. The value of securities issued by Natural Resources Companies may be affected by changes in overall market movements, changes in interest rates, or factors affecting a particular industry or commodity, such as weather, embargoes, tariffs, policies of commodity cartels and international economic, political and regulatory developments. The Investment Adviser’s judgments about trends in the prices of these securities and commodities may prove to be incorrect. It is possible that the performance of securities of Natural Resources Companies may lag the performance of other industries or the broader market as a whole. The Fund also invests in equity securities of Gold Companies. Equity securities of Gold Companies may experience greater volatility than companies not involved in the gold industry. Investments related to gold are considered speculative and are affected by a variety of worldwide economic, financial and political factors. The price of gold may fluctuate sharply, which has experienced substantial increases since August, 2020, but which also may be subject to substantial decreases, over short periods of time due to changes in inflation or expectations regarding inflation in various countries, the availability of supplies of gold, changes in industrial and commercial demand, gold sales by governments, central banks or international agencies, investment speculation, monetary and other economic policies of various governments and government restrictions on private ownership of gold. In times of significant inflation or great economic uncertainty, Gold Companies have at times outperformed securities markets generally. However, in times of stable economic growth, traditional equity and debt investments could offer greater appreciation potential and the value of gold and the prices of equity securities of Gold Companies may be adversely affected, which could in turn affect the Fund’s returns. Some Gold Companies hedge, to varying degrees, their exposure to declines in the price of gold. Such hedging limits a Gold Company’s ability to benefit from future rises in the price of gold. The Investment Adviser’s judgments about trends in the prices of securities of Gold Companies may prove to be incorrect. It is possible that the performance of securities of Gold Companies may lag the performance of other industries or the broader market as a whole. Supply and Demand Risk. A decrease in the production of or exploration of, gold, metals (including both precious metals—such as silver and platinum—and base (i.e., non-precious) metals—such as copper, lead, nickel and zinc), paper, food and agriculture, forestry products, gas, oil and other commodities or a decrease in the volume of such commodities available for transportation, mining, processing, storage or distribution may adversely impact the financial performance of the Fund’s investments. Production declines and volume decreases could be caused by various factors, including catastrophic events affecting production, depletion of resources, labor difficulties, environmental proceedings, increased regulations, equipment failures and unexpected maintenance problems, import supply disruption, increased competition from alternative energy sources or commodity prices. For example, the COVID-19 pandemic increased price and demand volatility for various natural resources, including oil, and companies within the natural resources industry, as demand drastically reduced at the height of the pandemic and significantly increased as the pandemic subsided. A similar or renewed and extended period of price and demand volatility, including reduced (or negative) prices, may significantly lengthen the time that companies within the natural resources industries would need to recover after a stabilization of prices. Such volatility may be further magnified by the 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. Future declines in demand for the indicated commodities could also adversely affect the financial performance of Natural Resources Companies and Gold Companies over the long term. Factors which could lead to a decline in demand include economic recession or other adverse economic conditions, higher fuel taxes or governmental regulations, increases in fuel economy, consumer shifts to the use of alternative fuel sources, changes in commodity prices, or weather. Depletion and Exploration Risk. Many Natural Resources Companies and Gold Companies are either engaged in the production or exploration of particular commodities or are engaged in transporting, storing, distributing and processing such commodities. To maintain or increase their revenue level, these companies or their customers need to maintain or expand their reserves through exploration of new sources of supply, the development of existing sources, acquisitions, or long-term contracts to acquire reserves. The financial performance of Natural Resources Companies and Gold Companies may be adversely affected if they, or the companies to whom they provide products or services, are unable to cost effectively acquire additional products or reserves sufficient to replace the natural decline. Regulatory Risk. Natural Resources Companies and Gold Companies may be subject to extensive government regulation in virtually every aspect of their operations, including how facilities are constructed, maintained and operated, environmental and safety controls, and in some cases the prices they may charge for the products and services they provide. Various governmental authorities have the power to enforce compliance with these regulations and the permits issued under them, and violators are subject to administrative, civil and criminal penalties, including civil fines, injunctions or both. Stricter laws, regulations or enforcement policies could be enacted in the future, which would likely increase compliance costs and may adversely affect the financial performance of Natural Resources Companies and Gold Companies. Commodity Pricing Risk. The operations and financial performance of Natural Resources Companies and Gold Companies may be directly affected by the prices of the indicated commodities, especially those Natural Resources Companies and Gold Companies for whom the commodities they own are significant assets. Commodity prices fluctuate for several reasons, including changes in market and economic conditions, levels of domestic production, impact of governmental regulation and taxation, the availability of transportation systems and, in the case of oil and gas companies in particular, conservation measures and the impact of weather. Volatility of commodity prices, which may lead to a reduction in production or supply, may also negatively affect the performance of Natural Resources Companies and Gold Companies which are solely involved in the transportation, processing, storing, distribution or marketing of commodities. Volatility of commodity prices may also make it more difficult for Natural Resources Companies and Gold Companies to raise capital to the extent the market perceives that their performance may be directly or indirectly tied to commodity prices. Catastrophe Risk. The operations of Natural Resources Companies and Gold Companies are subject to many hazards inherent in the development of energy infrastructure and the acquisition, exploration, production, mining, processing (including fractionating), refining, transportation (including trans-loading), storage, servicing or marketing of natural resources, including, but not limited to, crude oil, refined products, petrochemicals, natural gas, natural gas liquids, coal, metals and renewable energy sources, including damage to production equipment, pipelines, storage tanks or related equipment and surrounding properties caused by hurricanes, tornadoes, floods, fires and other natural disasters or by acts of terrorism; inadvertent damage from construction or other equipment; leaks of natural gas, natural gas liquids, crude oil, refined petroleum products or other hydrocarbons; and fires and explosions. These risks could result in substantial losses due to personal injury or loss of life, severe damage to and destruction of property and equipment and pollution or other environmental damage, and might result in the curtailment or suspension of their related operations. Not all Natural Resources Companies or Gold Companies are fully insured against all risks inherent to their businesses. If a significant accident or event occurs that is not fully insured, it could adversely affect a Natural Resources Company’s or Gold Company’s operations and financial condition. Recently, there have been physical and cyber terrorist attacks on natural gas and oil pipelines, resulting in significant destruction to critical property and equipment, supply disruption and the curtailment and suspension of certain Natural Resources Companies activities. Climate Change Risk. Climate change, and regulations intended to control its impact, may affect the value of the Fund’s investments. The Fund’s current evaluation is that the near-term effects of climate change and climate change regulation on the Fund’s investments are not material, but the Fund cannot predict the long-term impacts on the Fund or its investments from climate change or related regulations. The Fund is subject to the special risks associated with climate change. Weather may play a role in the cash flows of the Natural Resources Companies in which the Fund invests. Although many of the companies in this sector can reasonably predict seasonal weather patterns, extreme weather conditions, such as those that may result from climate change, many be unpredictable. The damage done by extreme weather could adversely affect the financial condition of such companies. Additionally, new or strengthened regulations or legislation could increase the operating costs and/or decrease the revenues of Natural Resources Companies. Interest Rate Risk for Natural Resources Companies and Gold Companies. The prices of the equity and debt securities of the Natural Resources Companies and Gold Companies that the Fund holds in its portfolio are susceptible in the short term to decline when interest rates rise. Rising interest rates could limit the capital appreciation of securities of certain investments because of the increased availability of alternative investments with yields comparable to those investments. Rising interest rates could adversely affect the financial performance of Natural Resources Companies and Gold Companies generally by increasing their cost of capital. This may reduce their ability to execute acquisitions or expansion projects in a cost-effective manner. Interest rates have risen in recent months, and the risk that they may continue to do so is pronounced. Cyber and Physical Security Risks. Natural Resources Companies 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 countries continue to investigate the incident, but several, including Sweden, have concluded the explosions were caused by grievous sabotage. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] | Risks Associated with Covered Calls and Other Option Transactions. There are several risks associated with transactions in options on securities. For example, there are significant differences between the securities and options markets that could result in an imperfect correlation between these markets, causing a given covered call option transaction not to achieve its objectives. A decision as to whether, when and how to use covered calls (or other options) involves the exercise of skill and judgment, and even a well-conceived transaction may be unsuccessful because of market behavior or unexpected events. The use of options may require the Fund to sell portfolio securities at inopportune times or for prices other than current market values, may limit the amount of appreciation the Fund can realize on an investment, or may cause the Fund to hold a security it might otherwise sell. As the writer of a covered call option, the Fund forgoes, during the option’s life, the opportunity to profit from increases in the market value of the security covering the call option above the exercise price of the call option, but has retained the risk of loss should the price of the underlying security decline. Although such loss would be offset in part by the option premium received, in a situation in which the price of a particular stock on which the Fund has written a covered call option declines rapidly and materially or in which prices in general on all or a substantial portion of the stocks on which the Fund has written covered call options decline rapidly and materially, the Fund could sustain material depreciation or loss in its net assets to the extent it does not sell the underlying securities (which may require it to terminate, offset or otherwise cover its option position as well). The writer of an option has no control over the time when it may be required to fulfill its obligation as a writer of the option. Once an option writer has received an exercise notice, it cannot effect a closing purchase transaction in order to terminate its obligation under the option and must deliver the underlying security at the exercise price. There can be no assurance that a liquid market will exist when the Fund seeks to close out an option position. Reasons for the absence of a liquid secondary market for exchange-traded options include the following: (i) there may be insufficient trading interest; (ii) restrictions may be imposed by an exchange on opening transactions or closing transactions or both; (iii) trading halts, suspensions or other restrictions may be imposed with respect to particular classes or series of options; (iv) unusual or unforeseen circumstances may interrupt normal operations on an exchange; (v) the trading facilities of an exchange or the Options Clearing Corporation (the “OCC”) may not be adequate to handle current trading volume; or (vi) the relevant exchange could, for economic or other reasons, decide or be compelled at some future date to discontinue the trading of options (or a particular class or series of options). If trading were discontinued, the secondary market on that exchange (or in that class or series of options) would cease to exist. However, outstanding options on that exchange that had been issued by the OCC as a result of trades on that exchange would continue to be exercisable in accordance with their terms. The Fund’s ability to terminate OTC options may be more limited than with exchange-traded options and may involve the risk that counterparties participating in such transactions will not fulfill their obligations. If the Fund were unable to close out a covered call option that it had written on a security, it would not be able to sell the underlying security unless the option expired without exercise. The hours of trading for options may not conform to the hours during which the underlying securities are traded. To the extent that the options markets close before the markets for the underlying securities, significant price and rate movements can take place in the underlying markets that cannot be reflected in the options markets. Call options are marked to market daily and their value will be affected by changes in the value of and dividend rates of the underlying common stocks, an increase in interest rates, changes in the actual or perceived volatility of the stock market and the underlying common stocks and the remaining time to the options’ expiration. Additionally, the exercise price of an option may be adjusted downward before the option’s expiration as a result of the occurrence of certain corporate events affecting the underlying equity security, such as extraordinary dividends, stock splits, merger or other extraordinary distributions or events. A reduction in the exercise price of an option would reduce the Fund’s capital appreciation potential on the underlying security. Limitation on Covered Call Writing Risk. The number of covered call options the Fund can write is limited by the number of shares of the corresponding common stock the Fund holds. Furthermore, the Fund’s covered call options and other options transactions will be subject to limitations established by each of the exchanges, boards of trade or other trading facilities on which such options are traded. These limitations govern the maximum number of options in each class which may be written or purchased by a single investor or group of investors acting in concert, regardless of whether the options are written or purchased on the same or different exchanges, boards of trade or other trading facilities or are held or written in one or more accounts or through one or more brokers. As a result, the number of covered call options that the Fund may write or purchase may be affected by options written or purchased by it and other investment advisory clients of the Investment Adviser. An exchange, board of trade or other trading facility may order the liquidation of positions found to be in excess of these limits, and it may impose certain other sanctions. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] | Risks Associated with Uncovered Calls. There are special risks associated with uncovered option writing which expose the Fund to potentially significant loss. As the writer of an uncovered call option, the Fund has no risk of loss should the price of the underlying security decline, but bears unlimited risk of loss should the price of the underlying security increase above the exercise price until the Fund covers its exposure. As with writing uncovered calls, the risk of writing uncovered put options is substantial. The writer of an uncovered put option bears a risk of loss if the value of the underlying instrument declines below the exercise price. Such loss could be substantial if there is a significant decline in the value of the underlying instrument. For combination writing, where the Fund writes both a put and a call on the same underlying instrument, the potential risk is unlimited. If a secondary market in options were to become unavailable, the Fund could not engage in losing transactions and would remain obligated until expiration or assignment. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

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 amount at the time the shareholder invested in the Fund, even after taking into account any reinvestment of distributions. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

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 will invest 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. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] | Distribution Risk for Equity Income Portfolio 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 or other distributions, however, does not guarantee that the issuer will continue to pay dividends or other distributions 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, an issuer 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. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

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 div-idends 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 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.

General Description of Registrant [Abstract] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Risk [Text Block] | Foreign Securities Risk. Because many of the world’s Natural Resources Companies and Gold Companies are located outside of the United States, the Fund may have a significant portion of its investments in securities that are traded in foreign markets and that are not subject to the requirements of the U.S. securities laws, markets and accounting requirements (“Foreign Securities”). 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. The governments of certain countries may prohibit or impose substantial restrictions on foreign investments in their capital markets or in certain industries, and there may be greater levels of price volatility in foreign markets. 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, and it may be difficult to effect repatriation of capital invested in certain countries. 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. The 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 publicly 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. Non-U.S. markets also have different clearance and settlement procedures which in some markets have at times failed to keep pace with the volume of transactions, thereby creating substantial delays and settlement failures that could adversely affect the Fund’s performance. 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 sponsored 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 objectives 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. Emerging Markets Risk. The considerations noted above in “Foreign Securities Risk” are generally intensified for investments in emerging market countries. Emerging market countries typically have economic and political systems that are less fully developed, and can be expected to be less stable than those of more developed countries. Investing in securities of companies in emerging markets may entail special risks relating to potential political and economic instability and the risks of expropriation, nationalization, confiscation or the imposition of restrictions on foreign investment, the lack of hedging instruments and restrictions on repatriation of capital invested. Economies of such countries can be subject to rapid and unpredictable rates of inflation or deflation. Emerging securities markets are substantially smaller, less developed, less liquid and more volatile than the major securities markets. The limited size of emerging securities markets and limited trading volume compared to the volume of trading in U.S. securities could cause prices to be erratic for reasons apart from factors that affect the quality of the securities. For example, limited market size may cause prices to be unduly influenced by traders who control large positions. Adverse publicity and investors’ perceptions, whether or not based on fundamental analysis, may decrease the value and liquidity of portfolio securities, especially in these markets. Other risks include high concentration of market capitalization and trading volume in a small number of issuers representing a limited number of industries, as well as a high concentration of investors and financial intermediaries; overdependence on exports, including gold and natural resources exports, making these economies vulnerable to changes in commodity prices; overburdened infrastructure and obsolete or unseasoned financial systems; environmental problems; less developed legal systems; and less reliable securities custodial services and settlement practices. Certain emerging markets may also face other significant internal or external risks, including the risk of war and civil unrest. For all of these reasons, investments in emerging markets may be considered speculative. 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 the Fund. 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 have adversely affected the value and exchange rate of the euro and pound sterling, and 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. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] | Income Risk. The income shareholders receive from the Fund is expected to be based primarily on income from short-term gains that the Fund earns from its investment strategy of writing covered calls and dividends and other distributions received from its investments. If the Fund’s covered call strategy fails to generate sufficient income from short-term gains or the distribution rates or yields of the Fund’s holdings decrease, shareholders’ income from the Fund could decline. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

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.” These securities, 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 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 market value of securities in lower grade categories is more volatile than that of higher quality securities, and the markets in which such lower grade 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. 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 issues 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. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] | Interest Rate Risk for Fixed Income Securities. The primary risk associated with fixed income securities is interest rate risk. A decrease in interest rates will generally result in an increase in the value of a fixed income security, while increases in interest rates will generally result in a decline in its value. This effect is generally more pronounced for fixed rate securities than for securities whose income rate is periodically reset. Interest rates have risen in recent months, and the risk that they may continue to do so is pronounced. See “—General Risks—Interest Rate Risks Generally.” Further, while longer term fixed rate securities may pay higher interest rates than shorter term securities, longer term fixed rate securities, like fixed rate securities, also tend to be more sensitive to interest rate changes and, accordingly, tend to experience larger changes in value as a result of interest rate changes. An increase in market interest rates will also generally result in a decrease in the price of any of the Fund’s outstanding preferred shares. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

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. Repeat occurrences of similar events 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. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Special Risks Related to Investment in Derivatives [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] | Special Risks Related to Investment in Derivatives. The Fund may participate in derivative transactions. Such transactions entail certain execution, market, liquidity, hedging and tax risks. Participation in the options or futures markets, in currency exchange transactions and in other 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, foreign currency, interest rate 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 options, foreign currency, futures contracts and options on futures contracts, securities indices and foreign currencies 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 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 comply with Rule 18f-4; and
| ● | the creditworthiness of counterparties.
Options, futures contracts, swaps contracts, and options thereon and forward contracts on securities and currencies may be traded on foreign exchanges. Such transactions may not be regulated as effectively as similar transactions in the United States, may not involve a clearing mechanism and related guarantees, and are subject to the risk of governmental actions affecting trading in, or the prices of, foreign securities. The value of such positions also could be adversely affected by (i) other complex foreign political, legal and economic factors, (ii) lesser availability than in the United States of data on which to make trading decisions, (iii) delays in the ability of the Fund to act upon economic events occurring in the foreign markets during non-business hours in the United States, (iv) the imposition of different exercise and settlement terms and procedures and margin requirements than in the United States and (v) less trading volume. Exchanges on which options, futures, swaps and options on futures or swaps are traded may impose limits on the positions that the Fund may take in certain circumstances. 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. Exchange-traded derivatives and OTC derivative transactions submitted for clearing through a central counterparty have become subject to minimum initial and variation margin requirements set by the relevant clearinghouse, as well as possible margin requirements mandated by the SEC or the CFTC. These regulators also have broad discretion to impose margin requirements on non-cleared OTC derivatives. These margin requirements will increase the overall costs for the Fund. While hedging transactions can reduce or eliminate losses, they can also reduce or eliminate gains. Hedges are sometimes subject to imperfect matching between the derivative and the underlying instrument, and there can be no assurance that the Fund’s hedging transactions will be effective. Derivatives may also 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. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

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 and options contracts, a clearing organization may use assets of a non-defaulting customer held in an omnibus account at the clearing organization to satisfy payment obligations of a defaulting customer of the clearing member to the clearing organization. As a result, in the event of a default or the clearing broker’s other clients or the clearing broker’s failure to extend own funds in connection with any such default, the Fund would not be able to recover the full amount of assets deposited by the clearing broker on its behalf with the clearing organization. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
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 obligations under a swap agreement will be accrued daily (offset against any amounts owing to the Fund) and any accrued but unpaid net amounts owed to a swap counterparty will be covered by the maintenance of liquid assets in accordance with SEC staff positions on the subject. 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. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

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. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

General Description of Registrant [Abstract] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
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. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
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. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Leverage Risk [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
General Description of Registrant [Abstract] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Risk [Text Block] | Leverage Risk. The Fund may use financial leverage for investment purposes. A leveraged capital structure would create special risks not associated with unleveraged funds that have a similar investment objectives 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 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 preferred shares or notes 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 Holders of Common Shares—Leverage Risk.” |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

General Description of Registrant [Abstract] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Risk [Text Block] | Market Discount Risk. The Fund is a non-diversified, closed-end management investment company. 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 long-term growth of capital. 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 objectives as well as the shareholder’s other investments when considering an investment in the Fund. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] | Portfolio Turnover Risk. The investment policies of the Fund, including its strategy of writing covered call options on securities in its portfolio, may result in portfolio turnover that is higher than that of many investment companies. Increased portfolio turnover rates will result in higher costs from brokerage commissions, dealer-mark-ups and other transaction costs and may also may decrease the after-tax return to individual investors in the Fund to the extent it results in a decrease in the portion of the Fund’s distributions that is attributable to long-term capital gain. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

General Description of Registrant [Abstract] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Risk [Text Block] | Non-Diversified Status. The Fund is classified as a “non-diversified” investment company under the 1940 Act, which means the Fund is not limited by the 1940 Act in the proportion of its assets that may be invested in the securities of a single issuer. As a non-diversified investment company, the Fund may invest in the securities of individual issuers to a greater degree than a diversified investment company. As a result, the Fund may be more vulnerable to events affecting a single issuer and therefore, subject to greater volatility than a fund that is more broadly diversified. Accordingly, an investment in the Fund may present greater risk to an investor than an investment in a diversified company. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

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

Risk [Text Block] | Dependence on Key Personnel. The Fund is dependent upon the expertise of Vincent Hugonnard-Roche as the sole option strategist on the Fund’s portfolio management team. If the Fund were to lose the services of Mr. Roche, it could be temporarily adversely affected until a suitable replacement could be found. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

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 (such as COVID-19), 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 on 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. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

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, on August 16, 2022, 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, including in respect of investment company names and other matters, 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(s). |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

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] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
General Description of Registrant [Abstract] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
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 NAV; violations of applicable privacy and other laws; regulatory fines, penalties, reputational damage, reimbursement or other compensation costs; and/ or additional compliance costs. The Fund may incur additional costs for cyber security risk management and remediation purposes. In addition, cyber security risks may also impact issuers of securities in which the Fund invests, which may cause the Fund’s investment in such issuers to lose value. There 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] | 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. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Restricted and Illiquid Securities Risk [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
General Description of Registrant [Abstract] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Risk [Text Block] | Restricted and Illiquid Securities Risk. 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 a security is valued for determining the Fund’s net asset value and the price the Fund actually receives upon sale. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

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

General Description of Registrant [Abstract] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
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 Declaration of Trust authorizes it to issue an unlimited number of shares. The Board may make certain amendments to the 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. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Legal, Tax and Regulatory Risks [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
General Description of Registrant [Abstract] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Risk [Text Block] | Legal, Tax and Regulatory Risks. Legal, tax and regulatory changes could occur that may have material adverse effects on the Fund. 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. 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, 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. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Risk [Text Block] | 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.

Special Risks to Holders of Common Shares [Member] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
General Description of Registrant [Abstract] |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
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 of the aggregate net asset value of their common shares. Such dilution 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, 2022, the amount of leverage represented approximately 21% 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 preferred shares or notes 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, 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. 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 annual rate of 1.00% 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 and do not reduce the principal due to noteholders on maturity or the liquidation preference to which preferred shareholders are entitled. 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 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, 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 21% of the Fund’s total net assets (the Fund’s amount of outstanding financial leverage as of December 31, 2022), and (2) charge interest or involve dividend payments at a projected blended annual average leverage dividend or interest rate of 5.20%, then the total return generated by the Fund’s portfolio (net of estimated expenses) must exceed approximately 1.16% 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 table 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 21% of the Fund’s net assets (the Fund’s outstanding financial leverage as of December 31, 2022), the Fund’s current projected blended annual average leverage dividend or interest rate of 5.20% (the average dividend rate on the Fund’s outstanding financial leverage as of December 31, 2022), a base management fee at an annual rate of 1.00% and estimated annual incremental expenses attributable to any outstanding preferred shares of approximately 0.06% 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 |  |  | (14.42 | )% |  |  | (8.06 | )% |  |  | (1.70 | )% |  |  | 4.66 | % |  |  | 11.02 | %
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 Risks to Holders of 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 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 its 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 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 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. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

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. For the fiscal year ended December 31, 2022, the Fund made distributions of $0.36 per common share, approximately $0.336 per common share which constituted a 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; 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. In order to obtain and maintain attractive credit quality ratings for preferred shares or notes, if desired, the Fund’s portfolio must satisfy over-collateralization tests established by the relevant rating agencies. These tests are more difficult to satisfy to the extent the Fund’s portfolio securities are of lower credit quality, longer maturity or not diversified by issuer and industry. These guidelines could affect portfolio decisions and may be more stringent than those imposed by the 1940 Act. A rating (if any) by a rating 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 (if any) does not address 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 notes or preferred shares, we may alter our portfolio or redeem the preferred securities or notes under certain circumstances. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

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. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

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 shareholders of the Fund and will vote together with holders of common shares 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 Shares, and the approval of two-thirds of each class, voting separately, of the Fund’s outstanding voting shares 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 $0.001 par value Preferred Shares. On October 26, 2017, the Fund issued 1,200,000 shares of 5.200% Series A Cumulative Preferred Shares (Series A Preferred), receiving $28,851,132, after the deduction of offering expenses of $203,868 and underwriting fees of $945,000. The Series A Preferred has a liquidation value of $25 per share and an annual dividend rate of 5.20%. The Board has authorized the repurchase of the Series A Preferred in the open market at prices less than $25 liquidation value per share. The Fund did not repurchase any Series A Preferred Shares in 2021. During the year ended December 31, 2022 the Fund repurchased and retired 2,139 Series A Preferred an investment of $50,082 and at an average discount of approximately 6.39% to its liquidation preference. At December 31, 2022, 1,167,963 shares were outstanding and accrued dividends amounted to $21,088. The Series A Preferred is senior to the common shares and results 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 Preferred are cumulative. The Fund is required by the 1940 Act and by the Statement of Preferences to meet certain asset coverage tests with respect to the Series A Preferred. 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 Preferred at the redemption price of $25 per share plus an amount equal to the accumulated and unpaid dividends whether or not declared on such shares in order to meet the 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 rate, which could have either a beneficial or detrimental impact on net investment income and gains available to common shareholders. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
