PROSPECTUS SUMMARY

This is only a summary. This summary may not contain all of the information that you should consider before investing in our securities. You should review the more detailed information contained in this prospectus (this “Prospectus”), including the section titled “Risk Factors and Special Considerations” beginning on page 49, the applicable Prospectus Supplement and the Statement of Additional Information, dated October 17, 2017 (the “SAI”).

SUMMARY OF FUND EXPENSES

The following table shows the Fund’s expenses, including preferred shares offering expenses, as a percentage of net assets attributable to common shares. All expenses of the Fund are borne, directly or indirectly, by the common shareholders.

The purpose of the table above and the example below is to help you understand the various costs and expenses that you, as a shareholder, would bear directly or indirectly. For a more complete description of the various costs and expenses a common shareholder would bear in connection with the issuance and ongoing maintenance of any preferred shares or notes issued by the Fund, see “Risk Factors and Special Considerations—Special Risks to Holders of Common Shares—Leverage Risk.”

The following example illustrates the expenses you would pay on a $1,000 investment in common shares, followed by a preferred share offering, assuming a 5% annual portfolio total return.* The expenses illustrated in the following example include the maximum estimated sales load on common shares of $10 and on preferred shares of $31.50, and estimated offering expenses of $4.16 from the issuance of $150 million in common shares and $50 million in preferred shares. The preferred shares sales load is spread over the Fund’s entire net assets attributable to common shares (assuming completion of the proposed issuances); therefore, the allocable portion of such sales load to a common shareholder making a $1,000 investment in these circumstances is estimated to be $5.30. The actual amounts in connection with any offering will be set forth in the Prospectus Supplement if applicable.

The example includes Dividends of 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): $33, $62, $94 and $182.

USE OF PROCEEDS

The Investment Adviser expects that it will initially invest the proceeds of the offering in high quality short term debt securities and instruments. The Investment Adviser anticipates that the investment of the proceeds will be made in accordance with the Fund’s investment objectives and policies as appropriate investment opportunities are identified, which is expected to substantially be completed within three months; however, changes in market conditions could result in the Fund’s anticipated investment period extending to as long as six months. This could occur because the Investment Adviser follows a value-oriented investment strategy; therefore market conditions could result in the Investment Adviser delaying the investment of proceeds if it believes the margin of risk in making additional investments is not favorable in light of its value-oriented investment strategy. See “Investment Objectives and Policies—Investment Methodology of the Fund” in the Prospectus. Depending on market conditions and operations, a portion of the proceeds to be identified in any relevant Prospectus Supplement any proceeds raised from this offering, may be used to pay distributions in accordance with the Fund’s distribution policy.

THE FUND

The Fund is a non-diversified, closed-end management investment company registered under the 1940 Act. The Fund was organized as a Delaware statutory trust on June 26, 2008. The Fund commenced investment operations on January 27, 2011. The Fund’s principal office is located at One Corporate Center, Rye, New York 10580-1422.

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 group of industries that constitute the natural resources industries, 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 prospectus, 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 Securities and Exchange Commission (the “Commission” or “SEC”) rules.

The percentage and ratings limitations stated herein and in the SAI 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 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 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 Prospectus, 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. When the Fund writes an uncovered call option or put option, it will segregate liquid assets with its custodian in an amount equal to the amount, adjusted daily, by which such option is in the money or will treat the unsegregated amount as borrowings. See “— Leverage” and “Risk Factors and Special Considerations — Risks Associated with Uncovered Calls.”

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 their 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 the Fund 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 “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. 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 are at historical lows and, therefore, it is likely that they will rise in the future.

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 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.

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) and the maintenance of collateral with its custodian. Although the Fund’s gain is limited to the price at which it sold the security short, its potential loss is theoretically unlimited.

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). See “Investment Restrictions” in the SAI.

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.

For the years ended December 31, 2015 and December 31, 2016, the portfolio turnover rate of the Fund was 58.0% and 183.0%, respectively.

Further information on the investment objectives and policies of the Fund is set forth in the SAI.

Leverage

The Fund may use leverage, including as a result of any issuances of preferred shares or notes pursuant to an applicable Prospectus Supplement. 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) 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. 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. 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. 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.

Additionally, the Fund may enter into derivative transactions that have economic leverage embedded in them. Derivative transactions that the Fund may enter into and the risks associated with them are described elsewhere in this Prospectus and in the SAI. 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.

To the extent the terms of such transactions obligate the Fund to make payments, the Fund may earmark or segregate cash or liquid assets in an amount at least equal to the current value of the amount then payable by the Fund under the terms of such transactions or otherwise cover such transactions in accordance with applicable interpretations of the staff of the SEC. If the current value of the amount then payable by the Fund under the terms of such transactions is represented by the notional amounts of such investments, the Fund would segregate or earmark cash or liquid assets having a market value at least equal to such notional amounts, and if the current value of the amount then payable by the Fund under the terms of such transactions is represented by the market value of the Fund’s current obligations, the Fund would segregate or earmark cash or liquid assets having a market value at least equal to such current obligations. To the extent the terms of such transactions obligate the Fund to deliver particular securities to extinguish the Fund’s obligations under such transactions the Fund may “cover” its obligations under such transactions by either (i) owning the securities or collateral underlying such transactions or (ii) having an absolute and immediate right to acquire such securities or collateral without additional cash consideration (or, if additional cash consideration is required, having earmarked or segregated an appropriate amount of cash or liquid assets). Such earmarking, segregation or cover is intended to provide the Fund with available assets to satisfy its obligations under such transactions. As a result of such earmarking, segregation or cover, the Fund’s obligations under such transactions will not be considered senior securities representing indebtedness for purposes of the 1940 Act, or considered borrowings subject to the Fund’s limitations on borrowings discussed above, but may create leverage for the Fund. To the extent that the Fund’s obligations under such transactions are not so earmarked, segregated or covered, such obligations may be considered “senior securities representing indebtedness” under the 1940 Act and therefore subject to the 300% asset coverage requirement.

These earmarking, segregation or cover requirements can result in the Fund maintaining securities positions it would otherwise liquidate, segregating or earmarking assets at a time when it might be disadvantageous to do so or otherwise 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. For a further description of such derivative instruments, see “Investment Objectives and Policies — Additional Investment Policies” in the SAI.

Options. The Fund may, from time to time, subject to guidelines of the Board and the limitations set forth in the Prospectus, 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 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; losses from investing in futures transactions that are potentially unlimited; and the segregation requirements described below.

Limitations on the Purchase and Sale of Futures Contracts, Certain Options, and Swaps. Subject to the guidelines of the Board, the Fund may engage in “commodity interest” transactions (generally, transactions in futures, certain options, certain currency transactions, and certain types of swaps) only for bona fide hedging or other permissible transactions in accordance with the rules and regulations of the Commodity Futures Trading Commission (“CFTC”). Pursuant to amendments by the CFTC to Rule 4.5 under the Commodity Exchange Act (“CEA”), the Investment Adviser has filed a notice of exemption from registration as a “commodity pool operator” with respect to the Fund. The Fund and the Investment Adviser are therefore not subject to registration or regulation as a commodity pool operator under the CEA. In addition, certain trading restrictions are applicable to the Fund as a result of this status. These trading restrictions permit the Fund to engage in commodity interest

transactions that include (i) “bona fide hedging” transactions, as that term is defined and interpreted by the CFTC and its staff, without regard to the percentage of the Fund’s assets committed to margin and options premiums and (ii) non-bona fide hedging transactions, provided that the Fund does not enter into such non-bona fide hedging transactions if, immediately thereafter, either (a) the sum of the amount of initial margin deposits on the Fund’s existing futures positions or swaps positions and option or swaption premiums would exceed 5% of the market value of the Fund’s liquidating value, after taking into account unrealized profits and unrealized losses on any such transactions, or (b) the aggregate net notional value of the Fund’s commodity interest transactions would not exceed 100% of the market value of the Fund’s liquidating value, after taking into account unrealized profits and unrealized losses on any such transactions. In addition to meeting one of the foregoing trading limitations, the Fund may not market itself as a commodity pool or otherwise as a vehicle for trading in the futures, options or swaps markets. Therefore, in order to claim the Rule 4.5 exemption, the Fund is limited in its ability to invest in commodity futures, options, and certain types of swaps (including securities futures, broad based stock index futures, and financial futures contracts). As a result, the Fund is more limited in its ability to use these instruments than in the past, and these limitations may have a negative impact on the ability of the Investment Adviser to manage the Fund, and on the Fund’s performance. If the Investment Adviser were 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.

Further information on the investment objectives and policies of the Fund is set forth in the SAI.

RISK FACTORS AND SPECIAL CONSIDERATIONS

Investors should consider the following risk factors and special considerations associated with investing in the Fund:

General Risks

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, 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 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. 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 may also experience greater price volatility than other types of common stocks. 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 Gold Companies. Securities of Gold Companies may experience greater volatility than companies not involved in the gold industries. 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, including 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 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. Sustained 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.

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 as a result 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. The risk of rising interest rates may be more pronounced because certain rates are near historical lows.

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 over-the-counter 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 net asset value of the Fund at the time the shareholder invested in the Fund, even after taking into account any reinvestment of distributions.

Common Stock Risk. Common stock of an issuer in the Fund’s portfolio may decline in price for a variety of reasons, including if the issuer fails to make anticipated dividend payments because, among other reasons, the issuer of the security experiences a decline in its financial condition. Common stock in which the Fund 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.

Interest Rate Risk. 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 its investment value. This effect is generally more pronounced for fixed rate securities than for securities whose income rate is periodically reset. Market interest rates are currently significantly below historical average rates and the Federal Reserve has begun to raise the Federal Funds rate, each of which results in more pronounced interest rate risk in the current market environment.

Additionally, during periods of declining interest rates, the issuer of a preferred stock or fixed income security may be able to exercise an option to prepay principal earlier than scheduled, forcing the Fund to reinvest in lower yielding securities. This is known as call or prepayment risk. Preferred stock and debt securities frequently have call features that allow the issuer to redeem the securities prior to their stated maturities. An issuer may redeem such a security if the issuer can refinance it at a lower cost due to declining interest rates or an improvement in the credit standing of the issuer. During periods of rising interest rates, the average life of certain types of securities may be extended because of slower than expected principal payments. This may prolong the length of time the security pays a below market interest rate, increase the security’s duration and reduce the value of the security. This is known as extension risk.

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

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

There may be less publicly available information about a foreign company than a U.S. company. Foreign securities markets may have substantially less volume than U.S. securities markets and some foreign company securities are less liquid 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. Foreign markets also have different clearance and settlement procedures that could cause the Fund to encounter difficulties in purchasing and selling securities on such markets and may result in the Fund missing attractive investment opportunities or experiencing loss. In addition, a portfolio that includes foreign securities can expect to have a higher expense ratio because of the increased transaction costs on non-U.S. securities markets and the increased costs of maintaining the custody of foreign securities.

The Fund also may purchase ADRs or U.S. dollar-denominated securities of foreign issuers. ADRs are receipts issued by U.S. banks or trust companies in respect of securities of foreign issuers held on deposit for use in the U.S. securities markets. While ADRs may not necessarily be denominated in the same currency as the securities into which they may be converted, many of the risks associated with foreign securities may also apply to ADRs. In addition, the underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited securities.

The following provides more detail on certain pronounced risks with foreign investing:

BREXIT Risks include short and long term market volatility and currency volatility, macroeconomic risk to the UK and European economies, impetus for further disintegration of the EU and related political stresses (including those related to sentiment against cross border capital movements and activities of investors like the Fund), prejudice to financial services businesses that are conducting business in the EU and which are based in the UK, disruption to regulatory regimes related to the operations of the Fund and the Investment Adviser, legal uncertainty regarding achievement of compliance with applicable financial and commercial laws and regulations in view of the expected steps to be taken pursuant to or in contemplation of Article 50 and negotiations undertaken under Article 218 of the Treaty on the Functioning of the European Union, and the unavailability of timely information as to expected legal, tax and other regimes.

In view of these risks and their application to the Investment Adviser and the Fund’s portfolio, prospective investors should take into account the significance of the BREXIT Risks, including the wide ranging and serious nature of these risks, and retain advice as needed, for purposes of evaluating an investment in the Fund. There can be no assurance that the BREXIT Risks will not alter, and alter significantly, the attractiveness of an investment in the Fund by, among other things, giving rise to impediments to the intended implementation of the business strategy of the Fund that would have material effects on performance, including the potential for capital losses, delays, legal and regulatory risk and general uncertainty.

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 debt 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:

In addition, the prices of these non-investment grade securities are more sensitive to negative developments, such as a decline in the issuer’s revenues or a general economic downturn, than are the prices of higher grade securities. Non-investment grade securities tend to be less liquid than investment grade securities. The market value of non-investment grade securities may be more volatile than the market value of investment grade securities and generally tends to reflect the market’s perception of the creditworthiness of the issuer and short term market developments to a greater extent than investment grade securities, which primarily reflect fluctuations in general levels of interest rates.

Ratings are relative and subjective and not absolute standards of quality. Securities ratings are based largely on the issuer’s historical financial condition and the rating agencies’ analysis at the time of rating. Consequently, the rating assigned to any particular security is not necessarily a reflection of the issuer’s current financial condition.

The Fund may purchase securities of companies that are experiencing significant financial or business difficulties, including companies involved in bankruptcy or other reorganization and liquidation proceedings. Although such investments may result in significant financial returns to the Fund, they involve a substantial degree of risk. The level of analytical sophistication, both financial and legal, necessary for successful investments in issuers experiencing significant business and financial difficulties is unusually high. There can be no assurance that the Fund will correctly evaluate the value of the assets collateralizing its investments or the prospects for a successful reorganization or similar action. In any reorganization or liquidation proceeding relating to a portfolio investment, the Fund may lose all or part of its investment or may be required to accept collateral with a value less than the amount of the Fund’s initial investment.

As a part of its investments in non-investment grade securities, the Fund may invest in the securities of issuers in default. The Fund invests in securities of issuers in default only when the Investment Adviser believes that such issuers will honor their obligations and emerge from bankruptcy protection and that the value of such issuers’ securities will appreciate. By investing in the securities of issuers in default, the Fund bears the risk that these issuers will not continue to honor their obligations or emerge from bankruptcy protection or that the value of these securities will not otherwise appreciate.

In addition to using statistical rating agencies and other sources, the Investment Adviser will also perform its own analysis of issuers in seeking investments that it believes to be underrated (and thus higher yielding) in light of the financial condition of the issuer. Its analysis of issuers may include, among other things, current and anticipated cash flow and borrowing requirements, value of assets in relation to historical cost, strength of management, responsiveness to business conditions, credit standing and current anticipated results of operations. In selecting investments for the Fund, the Investment Adviser may also consider general business conditions, anticipated changes in interest rates and the outlook for specific industries.

Subsequent to its purchase by the Fund, an issue of securities may cease to be rated or its rating may be reduced. In addition, it is possible that statistical rating agencies might change their ratings of a particular issue to reflect subsequent events on a timely basis. Moreover, such ratings do not assess the risk of a decline in market value. None of these events will require the sale of the securities by the Fund, although the Investment Adviser will consider these events in determining whether the Fund should continue to hold the securities.

Fixed income securities, including non-investment grade securities and comparable unrated securities, frequently have call or buy-back features that permit their issuers to call or repurchase the securities from their holders, such as the Fund. If an issuer exercises these rights during periods of declining interest rates, the Fund may have to replace the security with a lower yielding security, thus resulting in a decreased return for the Fund.

The market for non-investment grade and comparable unrated securities has at various times, particularly during times of economic recession, experienced substantial reductions in market value and liquidity. Past recessions have adversely affected the ability of certain issuers of such securities to repay principal and pay interest thereon. The market for those securities could react in a similar fashion in the event of any future economic recession.

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. Market interest rates are currently significantly below historical average rates and the Federal Reserve has begun to raise the Federal Funds rate, each of which results in more pronounced interest rate risk in the current market environment.

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. For more risks associated with fixed income securities, see “Investment Objectives and Policies — Additional Investment Policies” in the SAI.

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
