The Fund

The GAMCO Global Gold, Natural Resources & Income Trust is a non-diversified, closed-end management investment company organized under the laws of the State of Delaware. Throughout this Prospectus, we refer to the GAMCO Global Gold, Natural Resources & Income Trust as the “Fund” or as “we.” See “The Fund.”

The Offering

We may offer, from time to time, in one or more offerings, our common or preferred shares, $0.001 par value per share (together, “shares”). The shares may be offered at prices and on terms to be set forth in one or more supplements to this Prospectus (each a “Prospectus Supplement”). The offering price per share of our common shares will not be less than the net asset value per share of our common shares at the time we make the offering, exclusive of any underwriting commissions or discounts. You should read this Prospectus and the applicable Prospectus Supplement carefully before you invest in our shares. Our shares may be offered directly to one or more purchasers, through agents designated from time to time by us or to or through underwriters or dealers. The Prospectus Supplement relating to the offering will identify any agents, underwriters or dealers involved in the sale of our shares, and will set forth any applicable purchase price, fee, commission or discount arrangement between us and our agents or underwriters, or among our underwriters, or the basis upon which such amount may be calculated. The Prospectus Supplement relating to any sale of preferred shares will set forth the liquidation preference and information about the dividend period, dividend rate, any call protection or non-call period and other matters. While the aggregate number and amount of securities we may issue pursuant to this registration statement is limited to $             of shares, our Board of Trustees (each member a “Trustee”, and collectively the “Board”) may, without any action by the shareholders, amend our Agreement and Declaration of Trust from time to time to increase or decrease the aggregate number of shares or number of shares of any class or series that we have authority to issue. We may not sell any of our shares through agents, underwriters or dealers without delivery of a Prospectus Supplement describing the method and terms of the particular offering of our shares.

Our common shares are listed on the NYSE American under the symbol “GGN.” Our 5.00% Series B Cumulative Preferred Shares (“Series B Preferred Shares”) are listed on the NYSE American under the symbol “GGN PrB.” On May 24, 2019, the last reported sale price of our common shares was $4.36. The net asset value of the Fund’s common shares at the close of business on May 24, 2019 was $4.18 per share. As of May 24, 2019, the net assets of the Fund attributable to its common shares were $569,839,552. As of May 24, 2019, the Fund had outstanding 136,327,363 common shares. As of May 24, 2019, the Fund had outstanding 3,465,849 Series B Preferred at a liquidation value of $25 per share for a total liquidation value of $86,646,225.

securities of companies principally engaged in the group of industries that constitute the natural resources industries, which include companies principally engaged in the exploration, production or distribution of natural resources, such as gas, oil, paper, food and agriculture, forestry products, metals (other than gold) and minerals as well as related transportation companies and equipment manufacturers (“Natural Resources Companies”). The Fund may invest in the securities of companies located anywhere in the world and under normal market conditions will invest at least 40% of its assets in the securities of issuers located in at least three countries other than the United States.

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 the indicated businesses. An issuer will be treated as being located outside the United States if it is either organized or headquartered outside of the United States and has a substantial portion of its operations or sales outside the United States. Equity securities may include common stocks, preferred stocks, convertible securities, warrants, depository 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, derivative instruments, debt (including obligations of the United States government) and money market instruments. The Fund may invest up to 10% of its total assets in securities rated below investment grade by recognized statistical rating agencies or unrated securities of comparable quality, including securities of issuers in default, which are likely to have the lowest rating. 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 as “junk bonds” or “high yield” securities. As part of its investment strategy, the Fund intends to generate gains 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, indices comprised of Gold Companies or Natural Resources Companies or exchange traded funds comprised of such issuers and put options on securities in its portfolio. When the Fund sells a call option, it generates 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 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. See “Investment Objectives and Policies” in the Prospectus.

There is a risk that the Fund may generate losses as a result of its option strategy. See “Risk Factors and Special Considerations—Risks Associated with Covered Calls and Other Option Transactions” in the Prospectus.

The Fund is not intended for those who wish to exploit short term swings in the stock market.

No assurances can be given this the Fund’s objectives will be achieved.

Gabelli Fund LLC’s (the “Investment Adviser”) 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 and that allow the Fund to earn possible gains from writing covered calls on such stocks.

Preferred Shares and Borrowings

On May 7, 2013, the Fund completed the placement of $100 million of Cumulative Preferred Shares (“Preferred Shares”) consisting of 4 million shares designated as Series B Preferred Shares and paying dividends of an annual rate equal to 5.00% of liquidation preference. The Preferred Shares are senior to the common shares and result in the financial leveraging of the common shares. Such leveraging tends to magnify both the risks and opportunities to common shareholders. Dividends on the Preferred Shares are cumulative. The Fund is required by the Investment Company Act of 1940, as amended (the “1940 Act”) and by the Statement of Preferences to

meet certain asset coverage tests with respect to the Preferred Shares. If the Fund fails to meet these requirements and does not correct such failure, the Fund may be required to redeem, in part or in full, the Preferred Shares at the redemption price of $25 per share plus an amount equal to the accumulated and unpaid dividends whether or not declared on such shares in order to meet the requirements. Additionally, failure to meet the foregoing asset coverage requirements could restrict the Fund’s ability to pay dividends to common shareholders and could lead to sales of portfolio securities at inopportune times. The income received on the Fund’s assets may vary in a manner unrelated to the fixed rate, which could have either a beneficial or detrimental impact on net investment income and gains available to common shareholders. If the Fund has insufficient investment income and gains, all or a portion of the distributions to preferred shareholders would come from the common shareholders’ capital. Such distributions reduce the net assets attributable to common shareholders since the liquidation value of the preferred shareholders is constant.

The Fund may issue additional series of preferred shares or borrow money to leverage its investments. If the Fund’s Board determines that it may be advantageous to the holders of the Fund’s common shares for the Fund to utilize such leverage, the Fund may issue additional series of preferred shares or borrow money. Any preferred shares issued by the Fund will pay distributions either at a fixed rate or at rates that will be reset frequently based on short term interest rates. Any borrowings may also be at fixed or floating rates. Leverage creates a greater risk of loss as well as a potential for more gains for the common shares than if leverage were not used. See “Risk Factors and Special Considerations—Leverage Risks.” The Fund may also engage in investment management techniques which will not be considered senior securities if the Fund establishes in a segregated account cash or other liquid securities or sets aside assets on the accounting records equal to the Fund’s obligations in respect of such techniques. See “Risk Factors and Special Considerations—Special Risks of Derivative Transactions” in the Prospectus. These investment management techniques principally consists of writing options as described under “Investment Objectives and Policies.” See “Risk Factors and Special Considerations—Risks Associated with Covered Calls and Other Option Transactions” on page 33, “Risk Factors and Special Considerations—Leverage Risk” on page 34, and “Risk Factors and Special Considerations—Special Risks of Derivative Transactions” on page 42 of the Prospectus.

necessarily be taxed in the current period, it will have the effect of lowering the cost basis, which may lead to higher taxes upon the sale of the securities. Various factors will affect the level of the Fund’s income, such as its asset mix and use of covered call strategies. To permit the Fund to maintain more stable monthly distributions, the Fund may from time to time distribute less than the entire amount of income earned in a particular period, which would be available to supplement future distributions. As a result, the distributions paid by the Fund for any particular monthly period may be more or less than the amount of income actually earned by the Fund during that period. See “Dividends and Distributions” in the Prospectus.

The Fund’s distribution policy, including its policy to make regular monthly cash distributions, may be modified from time to time by the Board as it deems appropriate, including in light of market and economic conditions and the Fund’s current, expected, and historical earnings, and investment performance. Common shareholders are expected to be notified of any such modifications by press release or in the Fund’s periodic shareholder reports. Because the Fund’s income will fluctuate and the Fund’s distribution policy may be changed by the Board at any time, there can be no assurance that the Fund will pay distributions or dividends at a particular rate.

Investment company taxable income (including dividend income) and capital gain distributions paid by the Fund are automatically reinvested in additional shares of the Fund unless a shareholder elects to receive cash or the shareholder’s broker does not provide reinvestment services. See “Automatic Dividend Reinvestment and Voluntary Cash Purchase Plan” in the Prospectus.

Use of Proceeds

The Fund will use the net proceeds from the offering to purchase portfolio securities in accordance with its 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 if market conditions are unstable to such an extent that the Investment Adviser believes market risk is greater than the benefit of making additional investments at that time. Depending on market conditions and operations, a position of the proceeds to be identified in any relevant Prospectus Supplement may be used to pay distributions in accordance with the Fund’s distribution policy. See “Use of Proceeds” in the Prospectus.

Exchange Listing

The Fund’s common shares are listed on the NYSE American under the trading or “ticker” symbol “GGN.” The Fund’s Preferred Shares are listed on the NYSE American under the ticker symbol “GGN PrB.” See “Description of the Shares” in the Prospectus. The Fund’s common shares have historically traded at both a premium and discount to NAV. Since the Fund commenced trading on the NYSE American, the Fund’s common shares have traded at a discount to net asset value as high as [    ]% and a premium as high as [    ]%. Any additional series of fixed rate preferred shares issued by the Fund would also likely be listed on a stock exchange.

The common shares are designed primarily for long term investors, and you should not purchase common shares of the Fund if you intend to sell them shortly after purchase.

Fixed rate preferred shares may also trade at premiums to or discounts from their liquidation preference for a variety of reasons, including changes in interest rates.

Supply and Demand Risk.    A decrease in the production of, or exploitation of, gold, gas, oil, paper, food and agriculture, forestry products, metals (other than gold) or minerals 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 Gold Companies and Natural Resources 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. See “Risk Factors and Special Considerations—Industry Risks— Supply and Demand Risk” in the Prospectus.

Depletion and Exploration Risk.    Many Gold Companies and Natural Resources Companies are either engaged in the production or exploitation of the 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, through the development of existing sources, through acquisitions, or through long term contracts to acquire reserves. The financial performance of Gold Companies and Natural Resources 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. See “Risk Factors and Special Considerations—Industry Risks—Depletion and Exploration Risk” in the Prospectus.

Regulatory Risk.    Gold Companies and Natural Resources 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 Gold Companies and Natural Resources Companies. See “Risk Factors and Special Considerations—Industry Risks—Regulatory Risk” in the Prospectus.

Commodity Pricing Risk.    The operations and financial performance of Gold Companies and Natural Resources Companies may be directly affected by the prices of the indicated commodities, especially those Gold Companies and Natural Resources 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 Gold Companies and Natural Resources 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 Gold Companies and Natural Resources Companies to raise capital to the extent the market perceives that their performance may be directly or indirectly tied to commodity prices. See “Risk Factors and Special Considerations—Industry Risks—Commodity Pricing Risk” in the Prospectus. Additionally, the Fund relies on an exclusion from having to register as a “commodity pool operator” under the Commodity Exchange Act. If the Fund were to lose its ability to rely on this exclusion, compliance with additional registration and regulatory requirements would increase Fund expenses. See “Investment Objectives and Policies—Additional Risks Related to Derivative Investments—Limitations on the Purchase and Sale of Futures Contracts and Options on Futures Contracts” in the Statement of Additional Information.

Oil and Natural Gas Price Volatility Risk.    Crude oil and natural gas prices historically have been volatile and likely will continue to be volatile given current geopolitical conditions. The prices for crude oil and natural

gas are subject to a variety of factors beyond our control, such as the domestic and foreign supply of crude oil and natural gas; consumer demand for crude oil and natural gas, and market expectations regarding supply and demand. These factors and the volatility of the energy markets make it extremely difficult to predict price movements.

Climate Change Risk. Climate change, and regulations intended to control its impact, may affect the value of the Fund’s investments. The Fund’s current evaluation is that the near term effects of climate change and climate change regulation on the Fund’s investments are not material, but the Fund cannot predict the long term impacts on the Fund or its investments from climate change or related regulations. The ongoing political focus on climate change has resulted in various treaties, laws and regulations which are intended to limit carbon emissions. The Fund believes these laws being enacted or proposed may cause energy costs at properties owned by the real estate investment trusts (“REITs”) or other real estate companies in which the Fund invests to increase. The Fund does not expect the direct impact of such increases to be material to the value of its investments, because the increased costs either would be the responsibility of tenants or operators of properties owned by the REITs or other real estate companies in which the Fund invests, or, in the longer term, passed through and paid by the customers of such properties. There can be no assurance that climate change will not have a material adverse effect on the properties, operations or business of the Fund’s investments in REITs and other real estate companies.

The Fund cannot predict with certainty whether global warming or cooling is occurring and, if so, at what rate. However, the physical effects of climate change could have a material adverse effect on the properties, operations and business of the Fund’s investments in REITs and other real estate companies in certain geographical locations. To the extent climate change causes changes in weather patterns, properties in these markets could experience increases in storm intensity, flooding and rising sea-levels. Over time, these conditions could result in declining demand for the buildings owned by certain REITs and other real estate companies in which the Fund invests, or the inability of such REITs or other real estate companies to operate such buildings at all.

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 call options (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).

There can be no assurance that a liquid market will exist when the Fund seeks to close out an option position. 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. 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 may not be adequate to handle current trading volume; or (vi) the relevant exchange could discontinue the trading of options. In addition, the Fund’s ability to terminate over-the-counter (“OTC”) options may be more limited than with exchange-traded options and may involve the risk that counterparties participating

in such transactions will not fulfill their obligations. See “Risk Factors and Special Considerations—Risks Associated with Covered Calls and Other Option Transactions” in the Prospectus.

Limitation on Covered Call Writing Risk.    The number of covered call options the Fund can write is limited by the number of shares of 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. 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. See “Risk Factors and Special Considerations—Risks Associated with Covered Calls and Other Option Transactions—Limitation on Covered Call Writing Risk” in the Prospectus.

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. See “Risk Factors and Special Considerations—Risks Associated with Uncovered Calls” in the Prospectus.

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. See “Risk Factors and Special Considerations—Equity Risk” in the Prospectus.

Leverage Risk.    The use of leverage, which can be described as exposure to changes in price at a ratio greater than the amount of equity invested, either through the issuance of preferred shares, borrowing or other forms of market exposure, magnifies both the favorable and unfavorable effects of price movements in the investments made by the Fund. To the extent that the Fund is leveraged in its investment operations, the Fund will be subject to substantial risk of loss. The Fund cannot assure you that borrowings or the issuance of preferred shares will result in a higher yield or return to the holders of the common shares. As of December 31, 2018, the amount of leverage represented approximately 13% of the Fund’s net assets.

The Fund’s leveraged capital structure creates special risks not associated with unleveraged funds that have a similar investment objective and policies. These include the possibility of greater loss and the likelihood of higher volatility of the net asset value of the Fund and the asset coverage for the preferred shares. Such volatility may increase the likelihood of the Fund having to sell investments in order to meet its obligations to make distributions on the preferred shares or principal or interest payments on debt securities, or to redeem preferred shares or repay debt when it may be disadvantageous to do so. The Fund’s use of leverage may require it to sell portfolio investments at inopportune times in order to raise cash to redeem preferred shares or otherwise de-leverage so as to maintain required asset coverage amounts or comply with the mandatory redemption terms of any outstanding preferred shares. The use of leverage magnifies both the favorable and unfavorable effects of price movements in the investments made by the Fund. To the extent that the Fund employs leverage in its investment operations, the Fund is subject to substantial risk of loss. The Fund cannot assure you that the issuance of preferred shares will result in a higher yield or return to the holders of the common shares. Also, since the Fund utilizes leverage, a decline in net asset value could affect the ability of the Fund to make common share distributions and such a failure to make distributions could result in the Fund ceasing to qualify as a regulated investment company (a “RIC”) under the Internal Revenue Code of 1986, as amended (the “Code”).

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

In addition, the Fund pays (and the holders of common shares will bear) all costs and expenses relating to the issuance and ongoing maintenance of the preferred shares, including any distributions on preferred shares and any additional advisory fees.

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

Foreign Securities Risk.    Because many of the world’s Gold Companies and Natural Resources Companies are located outside of the United States, the Fund may have a significant portion of its investments in securities that are traded primarily in foreign markets and that are not subject to the requirements of the U.S. securities laws, markets and accounting requirements (“Foreign Securities”). Investments in Foreign Securities involve certain considerations and risks not ordinarily associated with investments in securities of U.S. issuers. Foreign companies are not generally subject to the same accounting, auditing and financial standards and requirements as 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, and 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. See “Risk Factors and Special Considerations—Foreign Securities Risk” in the Prospectus.

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

Foreign Currency Risk.    The Fund expects to invest in companies whose securities are denominated or quoted in currencies other than U.S. dollars or have significant operations or markets outside of the United States. In such instances, the Fund will be exposed to currency risk, including the risk of fluctuations in the exchange rate between U.S. dollars (in which the Fund’s shares are denominated) and such foreign currencies and the risk of currency devaluations. Certain non-U.S. currencies, primarily in developing countries, have been devalued in the past and might face devaluation in the future. Currency devaluations generally have a significant and adverse impact on the devaluing country’s economy in the short and intermediate term and on the financial condition and results of companies’ operations in that country. Currency devaluations may also be accompanied by significant declines in the values and liquidity of equity and debt securities of affected governmental and private sector entities generally. To the extent that affected companies have obligations denominated in currencies other than the devalued currency, those companies may also have difficulty in meeting those obligations under such circumstances, which in turn could have an adverse effect upon the value of the Fund’s investments in such companies. There can be no assurance that current or future developments with respect to foreign currency devaluations will not impair the Fund’s investment flexibility, its ability to achieve its investment objectives or the value of certain of its foreign currency denominated investments. See “Risk Factors and Special Considerations—Foreign Currency Risk” in the Prospectus.

Market Discount Risk.    Whether investors will realize gains or losses upon the sale of common shares of the Fund will depend upon the market price of the shares at the time of sale, which may be less or more than the Fund’s net asset value per share. Since the market price of the common shares will be affected by various factors as the Fund’s dividend and distribution levels (which are in turn affected by expenses) and stability, net asset value, market liquidity, the relative demand for and supply of the common shares in the market, unrealized gains, general market and economic conditions and other factors beyond the control of the Fund, we cannot predict whether the common shares will trade at, below or above net asset value or at, below or above the public offering price. Common shares of closed-end funds often trade at a discount from their net asset value and the Fund’s shares may trade at such a discount. This risk may be greater for investors expecting to sell their common shares of the Fund soon after completion of the public offering. The common shares of the Fund are designed primarily for long term investors, and investors in the common shares should not view the Fund as a vehicle for trading purposes. See “Risk Factors and Special Considerations—Market Discount Risk” in the Prospectus.

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. 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. See “Risk Factors and Special Considerations—Common Stock Risk” in the Prospectus.

Convertible Securities Risk.    Convertible securities generally offer lower interest or dividend yields than non-convertible securities of similar quality. The market values of convertible securities tend to decline as interest rates increase and, conversely, to increase as interest rates decline. In the absence of adequate anti-dilution provisions in a convertible security, dilution in the value of the Fund’s holding may occur in the event the underlying stock is subdivided, additional equity securities are issued for below market value, a stock dividend is declared, or the issuer enters into another type of corporate transaction that has a similar effect. See “Risk Factors and Special Considerations—Convertible Securities Risk” in the Prospectus.

Income Risk.    The income shareholders receive from the Fund is expected to be based primarily on income 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 or the distribution rates or yields of the Fund’s holdings decrease, shareholders’ income from the Fund could decline. See “Risk Factors and Special Considerations—Income Risk” in the Prospectus.

Distribution Risk for Equity Income Portfolio Securities.    The Fund intends to invest in the shares of issuers that pay dividends or other distributions. Such dividends or other distributions are not guaranteed, and an issuer may forgo paying dividends or other distributions at any time and for any reason. Dividend producing equity securities, in particular those whose market price is closely related to their yield, may exhibit greater sensitivity to interest rate changes. The Fund’s investments in dividend producing equity securities may also limit its potential for appreciation during a broad market advance. The prices of dividend producing equity securities can be highly volatile. Investors should not assume that the Fund’s investments in these securities will necessarily reduce the volatility of the Fund’s NAV or provide “protection,” compared to other types of equity securities, when markets perform poorly. See “Risk Factors and Special Considerations—Distribution Risk for Equity Income Portfolio Securities” in the Prospectus.

Special Risks Related to Preferred Securities.    Special risks associated with investing in preferred securities include deferral of distributions or dividend payments, in some cases the right of an issuer never to pay missed dividends, subordination to debt and other liabilities, illiquidity, limited voting rights and redemption by the issuer. Because the Fund has no limit on its investment in non-cumulative preferred securities, the amount of dividends the Fund pays may be adversely affected if an issuer of a non-cumulative preferred stock held by the Fund determines not to pay dividends on such stock. There is no assurance that dividends or distributions on preferred stock in which the Fund invests will be declared or otherwise made payable. See “Risk Factors and Special Considerations—Special Risks Related to Preferred Securities” in the Prospectus.

Interest Rate Risk.    Rising interest rates may adversely affect the financial performance of Gold Companies and Natural Resources Companies by increasing their costs of capital. This may reduce their ability to execute acquisitions or expansion projects in a cost-effective manner. The risks associated with rising interest rates are heightened given the historically low interest rate environment as of the date of this prospectus. The Fund may be subject to a greater risk of rising interest rates due to the current period of historically low interest rates. Recently, there have been some modest signs of inflationary price movements. There is a possibility that interest rates may rise, which would likely drive down the prices of income- or dividend-paying securities.

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. 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. See “Risk Factors and Special Considerations—Interest Rate Risk” in the Prospectus.

Inflation Risk.    Inflation risk is the risk that the value of assets or income from investments will be worth less in the future as inflation decreases the value of money. As inflation increases, the real value of the Fund’s shares and distributions thereon can decline. In addition, during any periods of rising inflation, dividend rates of any variable rate preferred shares or debt securities issued by the Fund would likely increase, which would tend to further reduce returns to common shareholders. See “Risk Factors and Special Considerations—Inflation Risk” in the Prospectus.

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

Illiquid Investments Risk.    Although the Fund expects that its portfolio will primarily be comprised of liquid securities, the Fund may invest in unregistered securities and otherwise illiquid investments. Unregistered securities are securities that cannot be sold publicly in the United States without registration under the Securities Act of 1933 (the “Securities Act”). An illiquid investment is a security or other investment that cannot be disposed of within seven days in the ordinary course of business at approximately the value at which the Fund has valued the investment. Unregistered securities often can be resold only in privately negotiated transactions with a limited number of purchasers or in a public offering registered under the Securities Act. Considerable delay could be encountered in either event and, unless otherwise contractually provided for, the Fund’s proceeds upon sale may be reduced by the costs of registration or underwriting discounts. The difficulties and delays associated with such transactions could result in the Fund’s inability to realize a favorable price upon disposition of unregistered securities, and at times might make disposition of such securities impossible. In addition, the Fund may be unable to sell other illiquid investments when it desires to do so, resulting in the Fund obtaining a lower price or being required to retain the investment. Illiquid investments generally must be valued at fair value, which is inherently less precise than utilizing market values for liquid investments, and may lead to differences between the price at which a security is valued for determining the Fund’s net asset value and the price the Fund actually receives upon sale. See “Risk Factors and Special Considerations—Illiquid Investments Risk” in the Prospectus.

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

Special Risks of Derivative Transactions.    The Fund may participate in derivative transactions. Such transactions entail certain execution, market, liquidity, hedging and tax risks. Participation in the options or futures markets, in other derivatives transactions, or in currency exchange transactions involves investment risks and transaction costs to which the Fund would not be subject absent the use of these strategies. If the Investment Adviser’s prediction of movements in the direction of the securities, foreign currency, interest rate or other referenced instruments or markets is inaccurate, the consequences to the Fund may leave the Fund in a worse position than if it had not used such strategies. See “Risk Factors and Special Considerations—Special Risks of Derivative Transactions” in the Prospectus.

Non-Investment Grade Securities Risk.    The Fund may invest its assets in securities rated below investment grade by recognized statistical rating agencies or unrated securities of comparable quality. The prices of these lower grade securities are more sensitive to negative developments, such as a decline in the issuer’s revenues or a general economic downturn, than are the prices of higher grade securities. Securities of below investment grade quality—those securities rated below “Baa” by Moody’s or below “BBB” by S&P (or unrated securities of comparable quality)—are predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal when due and therefore involve a greater risk of default. Securities rated below investment grade

commonly are referred to as “junk bonds” or “high yield” securities. See “Risk Factors and Special Considerations—Non-Investment Grade Securities Risk” in the Prospectus.

Dependence on Key Personnel.    The Investment Adviser is dependent upon the expertise of Mr. Mario J. Gabelli. If the Investment Adviser were to lose the services of Mr. Gabelli, it could be adversely affected. There can be no assurance that a suitable replacement could be found for Mr. Gabelli in the event of his death, resignation, retirement or inability to act on behalf of the Investment Adviser.

The Fund is dependent upon the expertise of Vincent Hugonnard-Roche as the sole option strategist on the Fund’s portfolio management team. If the Fund were to lose the services of Mr. Roche, it could be temporarily adversely affected until a suitable replacement could be found. See “Risk Factors and Special Considerations—Dependence on Key Personnel” in the Prospectus.

Long Term Objective; Not a Complete Investment Program.    The Fund is intended for investors seeking a high level of current income. The Fund is not meant to provide a vehicle for those who wish to exploit short term swings in the stock market. An investment in shares of the Fund should not be considered a complete investment program. Each shareholder should take into account the Fund’s investment objectives as well as the shareholder’s other investments when considering an investment in the Fund. See “Risk Factors and Special Considerations—Long Term Objective; Not a Complete Investment Program” in the Prospectus.

Management Risk.    The Fund is subject to management risk because its portfolio is actively managed. The Investment Adviser applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these will produce the desired results. See “Risk Factors and Special Considerations—Management Risk” in the Prospectus.

Portfolio Turnover.    The Fund may have a high turnover ratio which may result in higher expenses and lower after-tax return to shareholders than if the Fund had a lower turnover ratio.

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

Market Disruption and Geopolitical Risk.    The occurrence of events similar to those in recent years, such as the aftermath of the war in Iraq, instability in Afghanistan, Pakistan, Egypt, Libya, Syria, Russia, Ukraine and the Middle East, ongoing epidemics of infectious diseases in certain parts of the world, natural/environmental disasters, terrorist attacks in the United States and around the world, social and political discord, debt crises (such as the Greek crisis), sovereign debt downgrades, increasingly strained relations between the United States and a number of foreign countries, including traditional allies, such as certain European countries, and historical adversaries, such as North Korea, Iran, China and Russia, and the international community generally, new and continued political unrest in various countries, such as Venezuela and Spain, the exit or potential exit of one or more countries from the European Union (the “EU”) or the European Monetary Union (the “EMU”), continued changes in the balance of political power among and within the branches of the U.S. government, government shutdowns, among others, may result in market volatility, may have long term effects on the U.S. and worldwide financial markets, and may cause further economic uncertainties in the United States and worldwide. See “Risk Factors and Special Considerations—Market Disruption and Geopolitical Risk” in the Prospectus.

Economic Events and Market Risk.    Periods of market volatility remain, and may continue to occur in the future, in response to various political, social and economic events both within and outside of the United States. These conditions have resulted in, and in many cases continue to result in, greater price volatility, less liquidity, widening credit spreads and a lack of price transparency, with many securities remaining illiquid and of uncertain

value. Such market conditions may make valuation of some of the Fund’s securities uncertain and/or result in sudden and significant valuation increases or declines in its holdings. If there is a significant decline in the value of the Fund’s portfolio, this may impact the asset coverage levels for the Fund’s outstanding leverage.

Risks resulting from any future debt or other economic crisis could also have a detrimental impact on the global economic recovery, the financial condition of financial institutions and our business, financial condition and results of operation. Downgrades to the credit ratings of major banks could result in increased borrowing costs for such banks and negatively affect the broader economy. Moreover, Federal Reserve policy, including with respect to certain interest rates, may also adversely affect the value, volatility and liquidity of dividend- and interest-paying securities. Market volatility, rising interest rates and/or a return to unfavorable economic conditions could impair the Fund’s ability to achieve its investment objectives. See “Risk Factors and Special Considerations—Economic Events and Market Risk” in the Prospectus.

Regulation and Government Intervention Risk.    The U.S. government and certain foreign governments have in the past taken actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility, and in some cases a lack of liquidity, including through direct purchases of equity and debt securities. Federal, state, and other governments, their regulatory agencies or self-regulatory organizations may take actions that affect the regulation of the issuers in which the Fund invests, or the issuers of such securities, in ways that are unforeseeable. Legislation or regulation may also change the way in which the Fund itself is regulated. Such legislation or regulation could limit or preclude the Fund’s ability to achieve its investment objectives. The Investment Adviser will monitor developments and seek to manage the Fund’s portfolio in a manner consistent with achieving the Fund’s investment objectives, but there can be no assurance that it will be successful in doing so. See “Risk Factors and Special Considerations—Regulation and Government Intervention Risk” in the Prospectus.

Anti-Takeover Provisions.    The Fund’s governing documents include provisions that could limit the ability of other entities or persons to acquire control of the Fund or convert the Fund to an open-end fund. See “Risk Factors and Special Considerations—Anti-Takeover Provisions” and “Anti-Takeover Provisions of the Fund’s Governing Documents” in the Prospectus.

Special Risks to Holders of Preferred Shares.

Management and Fees

Gabelli Funds, LLC serves as the Fund’s Investment Adviser and is compensated for its services and its related expenses at an annual rate of 1.00% of the Fund’s average weekly net assets, as defined in the Fund’s investment advisory agreement, with no deduction for the liquidation preference of any outstanding preferred shares. Consequently, if the Fund has preferred shares outstanding, the management fee as a percentage of net assets attributable to the common shares will be higher. The Investment Adviser is responsible for administration of the Fund and currently utilizes and pays the fees of a third party sub-administrator.

Because the investment advisory fees are based on a percentage of managed assets, which includes assets attributable to the Fund’s use of leverage, the Investment Adviser may have a conflict of interest in the input it provides to the Board regarding whether to use or increase the Fund’s use of leverage. There may be cases in which the Fund determines to borrow or use other forms of leverage. The Board bases its decision, with input from the Investment Adviser, regarding whether and how much leverage to use for the Fund on its assessment of whether such use of leverage is in the best interests of the Fund. The Board seeks to manage the Investment Adviser’s potential conflict of interest by retaining the final decision on these matters and by periodically reviewing the Fund’s performance and use of leverage. See “Management of the Fund” in the Prospectus.

Repurchase of Common Shares

The Fund’s Board of Trustees has authorized the Fund (and the Fund accordingly reserves freedom of action) to repurchase its common shares in the open market when the common shares are trading at a discount of 7.5% or more from net asset value (or such other percentage as the Board of Trustees may determine from time to time). The Fund generally intends to finance common share repurchases with cash on hand and, while the Fund may incur debt to finance common share repurchases, such debt financing would require further approval of the Board, and the Fund does not currently intend to incur debt to finance common share repurchases. The Fund has repurchased its common shares under this authorization. See “Description of the Shares—Common Shares” in the Prospectus. Although the Board of Trustees has authorized such repurchases, the Fund is not required to repurchase its common shares, and the Fund’s officers, in determining whether to repurchase Fund common shares pursuant to this authority, take into account a variety of market and economic factors including, among other things, trading volume, the magnitude of discount, bid/ask spreads, the Fund’s available cash position, leverage and expense ratios, and any applicable legal or contractual restrictions on such repurchases that

may be applicable at the time. The Board of Trustees has not established a limit on the number of shares that could be purchased during such period. In total through December 31, 2018, the Fund has repurchased and retired 231,803 common shares in the open market at an average price of $7.28 per share and at an average discount of approximately 10.55% from the Fund’s net asset value. Such repurchases are subject to certain notice and other requirements under the 1940 Act. During the year ended December 31, 2018, the Fund did not repurchase any common shares. See “Repurchase of Common Shares” in the Prospectus.

Anti-Takeover Provisions

Certain provisions of the Fund’s Agreement and Declaration of Trust and By-Laws (collectively, the “Governing Documents”) may be regarded as “anti-takeover” provisions. Pursuant to these provisions, only one of three classes of Trustees is elected each year, and the affirmative vote of the holders of 75% of the outstanding shares of the Fund are necessary to authorize the conversion of the Fund from a closed-end to an open-end investment company or to authorize certain transactions between the Fund and a beneficial owner of more than 5% of any class of the Fund’s capital stock. The overall effect of these provisions is to render more difficult the accomplishment of a merger with, or the assumption of control by, a principal shareholder. These provisions may have the effect of depriving Fund common shareholders of an opportunity to sell their shares at a premium to the prevailing market price. The issuance of preferred shares could make it more difficult for the holders of common shares to avoid the effect of these provisions. See “Anti-Takeover Provisions of the Fund’s Governing Documents” in the Prospectus.

Custodian, Transfer Agent and Dividend Disbursing Agent

The Bank of New York Mellon, located at 135 Santilli Highway, Everett, Massachusetts 02149, serves as the custodian (the “Custodian”) of the Fund’s assets pursuant to a custody agreement. Under the custody agreement, the Custodian holds the Fund’s assets in compliance with the 1940 Act. For its services, the Custodian will receive a monthly fee paid by the Fund based upon, among other things, the average value of the total assets of the Fund, plus certain charges for securities transactions and out-of-pocket expenses.

American Stock Transfer & Trust Company (“American Stock Transfer”), located at 6201 15th Avenue, Brooklyn, New York 11219, serves as the Fund’s distribution disbursing agent, as agent under the Fund’s automatic dividend reinvestment and voluntary cash purchase plan and as transfer agent and registrar with respect to the common and preferred shares of the Fund.
