held in cash or invested in all types of securities in whatever amounts or proportions the Investment Manager (defined below) believes is best suited to current and anticipated economic and market conditions. These may include preferred and common
stocks, debt securities, repurchase agreements, derivatives (including futures contracts), illiquid securities and securities of foreign issuers (including emerging markets issuers), each of which could involve certain risks. The Fund also employs
leverage through its outstanding shares of Preferred Stock. See <FONT style="font-style:italic;">More Information About the Fund &#8211; Investment Objective and Policies</FONT> below.</DIV>

purchased and sold from time to time by the Service Agent, as directed by the stockholders of accounts held directly with the Fund and not through a financial intermediary (Direct-at-Fund Accounts). See <FONT style="font-style:italic;">Buying and
Selling Shares</FONT>. Shares will be purchased on the Exchange or elsewhere when the market price of the Common Stock is equal to or less than its net asset value, and any brokerage commissions applicable to such purchases will be charged pro rata
to the Direct-at-Fund Account stockholders directing such purchases. Shares will be purchased from the Fund at net asset value when the net asset value is lower than the market price, all as more fully described in this prospectus.</DIV>

the Fund&#8217;s stock repurchase program for 2020. Identical to the Fund&#8217;s 2019 stock repurchase program, under the Fund&#8217;s 2020 stock repurchase program, the Fund repurchases up to 5% of the Fund&#8217;s outstanding Common Stock during
the year directly from stockholders and in the open market, provided that, with respect to shares purchased in the open market, the excess of the net asset value of a share of Common Stock over its market price (the discount) is greater than 10%.
During 2019, the Fund purchased 1,158,674 shares of Common Stock in the open market. The intent of the stock repurchase program is, among other things, to moderate the growth in the number of shares of Common Stock outstanding, increase the net
asset value (NAV) of the Fund&#8217;s outstanding shares, reduce the dilutive impact on stockholders who do not take capital gains distributions in additional shares and increase the liquidity of the Fund&#8217;s Common Stock in the
marketplace.</DIV> </DIV> <DIV style="margin-top:78pt;width:91.43%;" type="Block"> <DIV style="text-align:left;">

included in the Fund&#8217;s annual report, which is available upon request. The information for the prior fiscal years has been derived from the financial statements audited by the Fund&#8217;s former independent registered public accounting firm.
The Financial Highlights should be read in conjunction with the financial statements and notes contained in the Fund&#8217;s 2019 annual report, which may be obtained from the Service Agent as provided in this Prospectus.</DIV>

to trace the operating performance, on a per Common Stock share basis, from the beginning net asset value to the ending net asset value, so that you can understand what effect the individual items have on your investment, assuming it was held
throughout the period. Generally, the per share amounts are derived by converting the actual dollar amounts incurred for each item, as disclosed in the financial statements, to their equivalent per Common Stock share amounts, using average Common
Stock shares outstanding during the period.</DIV> <DIV style="color:#003C78;font-family:Arial;font-size:10pt;font-style:Normal;font-weight:Normal;line-height:12pt;margin-top:4pt;text-align:left;text-decoration:none;text-transform:none;">Total return
measures the Fund&#8217;s performance assuming that you purchased shares of the Fund at the market price or net asset value as of the beginning of the period, invested all Fund distributions, and then sold your shares at the closing market price or

by the consolidation of two predecessor corporations. It is registered under the 1940 Act as a diversified management investment company of the closed-end type.</DIV>
<DIV style="color:#003C78;font-family:Arial;font-size:13pt;font-style:Normal;font-weight:bold;line-height:15pt;margin-top:9pt;text-align:left;text-decoration:none;text-transform:none;">Investment Objective and Policies</DIV>

income while providing reasonable current income. The Fund&#8217;s investment objective is not a fundamental policy and may be changed by the Fund&#8217;s Board of Directors without stockholder approval. Because any investment involves risk, there
is no assurance the Fund&#8217;s investment objective will be achieved.</DIV>
<DIV style="color:#003C78;font-family:Arial;font-size:10pt;font-style:Normal;font-weight:Normal;line-height:12pt;margin-top:4pt;text-align:left;text-decoration:none;text-transform:none;">The Fund invests primarily for the longer term and has no
charter restrictions with respect to such investments. With respect to the Fund&#8217;s investments, assets may be held in cash or invested in all types of securities, that is, in common stocks, bonds, convertible bonds (including high yield
instruments), debentures, notes, preferred and convertible preferred stocks, rights, and other securities or instruments, in whatever amounts or proportions the Investment Manager believes best suited to current and anticipated economic and market
conditions.</DIV> <DIV style="color:#003C78;font-family:Arial;font-size:10pt;font-style:Normal;font-weight:Normal;line-height:12pt;margin-top:4pt;text-align:left;text-decoration:none;text-transform:none;">The Fund may invest in debt/fixed income
instruments and convertible securities that, at the time of purchase, are rated below investment grade or are unrated but determined to be of comparable quality (commonly referred to as &#8220;high yield&#8221; investments or &#8220;junk&#8221;
bonds). The Fund may invest in debt instruments of any maturity and does not seek to maintain a particular dollar-weighted average maturity. A bond is issued with a specific maturity date, which is the date when the issuer must pay back the
bond&#8217;s principal (face value). Bond maturities range from less than 1 year to more than 30 years. Typically, the longer a bond&#8217;s maturity, the more price risk the Fund and the Fund&#8217;s investors face as interest rates rise, but the
Fund could receive a higher yield in return for that longer maturity and higher interest rate risk.</DIV>

investments, including emerging markets. The Fund also employs leverage through its outstanding shares of Preferred Stock.</DIV>

by the Fund&#8217;s Board without stockholder approval, unless such a change would change the Fund&#8217;s status from a &#8220;diversified&#8221; to a &#8220;non-diversified&#8221; company under the 1940 Act. For purposes of applying the limitation
set forth in its issuer diversification policy, under certain circumstances, the Fund may treat an investment, if any, in a municipal bond refunded with escrowed U.S. Government securities as an investment in U.S. Government securities.</DIV>

senior securities, the borrowing of money, the underwriting of securities of other issuers, the concentration of investments in a particular industry or groups of industries, the purchase or sale of real estate, the purchase or sale of commodities
or commodity contracts, and the making of loans. These policies may not be changed without a vote of stockholders. A more detailed description of the Fund&#8217;s investment policies, including a list of those restrictions on the Fund&#8217;s
investment activities which cannot be changed without such a vote, appears in the SAI. Within the limits of these fundamental policies, the Investment Manager has reserved freedom of action.</DIV>

securities of companies in any one industry. The Fund may, however, invest a substantial percentage of its assets in certain industries or economic sectors believed to offer good investment opportunities, including the information technology sector.

Risk</FONT>, and&#160;<FONT style="font-weight:bold;">Convertible Securities Risk</FONT>, among others. Descriptions of these and other principal risks of investing in the Fund are provided below. <FONT style="font-style:italic;">There is no
assurance that the Fund will achieve its investment objective and you may lose money</FONT>. The value of the Fund&#8217;s holdings may decline, and the Fund&#8217;s net asset value (NAV) and share price may go down. An investment in the Fund is not
a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.</DIV>

Fund is actively managed and its performance therefore will reflect, in part, the ability of the portfolio managers to make investment decisions that seek to achieve the Fund&#8217;s investment objective. Due to its active management, the Fund could
underperform its benchmark index and/or other funds with similar investment objectives and/or strategies.</FONT></DIV>

 style="font-weight:Normal;"> The Fund normally expects to receive income which may include interest, dividends and/or capital gains, depending upon its investments. The distribution amounts paid by the Fund will vary and generally depend on the
amount of income the Fund earns (less expenses) on its portfolio holdings, and capital gains or losses it recognizes. A decline in the Fund&#8217;s income or net capital gains arising from its investments may reduce its distribution
level.</FONT></DIV> <DIV style="color:#003C78;font-family:Arial;font-size:10pt;font-style:Normal;font-weight:bold;line-height:12pt;margin-top:4pt;text-align:left;text-decoration:none;text-transform:none;">Convertible Securities Risk. <FONT
 style="font-weight:Normal;">Convertible securities are subject to the usual risks associated with debt instruments, such as interest rate risk (the risk of losses attributable to changes in interest rates) and credit risk (the risk that the issuer
of a debt instrument will default or otherwise become unable, or be perceived to be unable or unwilling, to honor a financial obligation, such as making payments to the Fund when due). Convertible securities also react to changes in the value of the
common stock into which they convert, and are thus subject to market risk (the risk that the market values of securities or other investments that the Fund holds will fall, sometimes rapidly or unpredictably, or fail to rise). Because the value of a
convertible security can be influenced by both interest rates and the common stock's market movements, a convertible security generally is not as sensitive to interest rates as a similar debt instrument, and generally will not vary in value in
response to other factors to the same extent as the underlying common stock. In the event of a liquidation of the issuing company, holders of convertible securities would typically be paid before the company's common stockholders but after holders
of any senior debt obligations of the company. The Fund may be forced to convert a convertible security before it otherwise would choose to do so, which may decrease the Fund's return.</FONT></DIV>

and any recovery may be significantly delayed. Transactions that the Fund enters into may involve counterparties in the financial services sector and, as a result, events affecting the financial services sector may cause the Fund&#8217;s share value

 style="font-weight:Normal;"> Credit risk is the risk that the value of debt instruments may decline if the issuer thereof defaults or otherwise becomes unable or unwilling, or is perceived to be unable or unwilling, to honor its financial
obligations, such as making payments to the Fund when due. Various factors could affect the actual or perceived willingness or ability of the issuer to make timely interest or principal payments, including changes in the financial condition of the
issuer or in general economic conditions. Credit rating agencies assign credit ratings to certain debt instruments to indicate their credit risk. Unless otherwise provided in the Fund&#8217;s Principal Investment Strategies, investment grade debt
instruments are those rated at or above BBB- by S&amp;P Global Ratings, or equivalently rated by Moody&#8217;s Investors Service, Inc. or Fitch Ratings, Inc., or, if unrated, determined by the management team to be of comparable quality. Conversely,
below investment grade (commonly called &#8220;high-yield&#8221; or &#8220;junk&#8221;) debt instruments are those rated below BBB- by S&amp;P Global Ratings, or equivalently rated by Moody&#8217;s Investors Service, Inc. or Fitch Ratings, Inc., or,
if unrated, determined by the management team to be of comparable quality. A rating downgrade by such agencies can negatively impact the value of such instruments. Lower quality or unrated instruments held by the Fund may present increased credit
risk as compared to higher-rated instruments. Non-investment grade debt instruments may be subject to greater price fluctuations and are more likely to experience a default than investment grade debt instruments and therefore may expose the Fund to
increased credit risk. If the Fund purchases unrated instruments, or if the ratings of instruments held by the Fund are lowered after purchase, the Fund will depend on analysis of credit risk more heavily than usual.</FONT></DIV>
<DIV style="color:#003C78;font-family:Arial;font-size:10pt;font-style:Normal;font-weight:bold;line-height:12pt;margin-top:4pt;text-align:left;text-decoration:none;text-transform:none;">Derivatives Risk. <FONT style="font-weight:Normal;">Derivatives
may involve significant risks. Derivatives are financial instruments, traded on an exchange or in the over-the-counter (OTC) markets, with a value in relation to, or derived from, the value of an underlying asset(s) (such as a security, commodity or
currency) or other reference, such as an index, rate or other economic indicator (each an underlying reference). Derivatives may include those that are privately placed or otherwise exempt from SEC registration, including certain Rule 144A eligible
securities. Derivatives could result in Fund losses if the underlying reference does not perform as anticipated. Use of derivatives is a highly specialized activity that can involve investment techniques, risks, and tax planning different from those
associated with more traditional investment instruments. The Fund&#8217;s derivatives strategy may not be successful and use of certain derivatives could result in substantial, potentially unlimited, losses to the Fund regardless of the Fund&#8217;s
actual investment. A relatively small movement in the price, rate or other economic indicator associated with the underlying reference may result in substantial loss for the Fund. Derivatives may be more volatile than other types of investments.
Derivatives can increase the Fund&#8217;s risk exposure to underlying references and their attendant risks, including the risk of an adverse credit event associated with the underlying reference (credit risk), the risk of an adverse movement in the
value, price or rate of the underlying reference (market risk), the risk of an adverse movement in the value of underlying currencies (foreign currency risk) and the risk of an adverse movement in underlying interest rates (interest rate risk).
Derivatives may expose the Fund to additional risks, including the risk of loss due to a derivative position that is imperfectly correlated with the underlying reference it is intended to hedge or replicate (correlation risk), the risk that a
counterparty will fail to perform as agreed (counterparty risk), the risk that a hedging strategy may fail to mitigate losses, and may offset gains (hedging risk), the risk that the return on an investment may not keep pace with inflation (inflation
risk), the risk that losses may be greater than the amount invested (leverage risk), the risk that the Fund may be unable to sell an investment at an advantageous time or price (liquidity risk), the risk that the investment may be difficult to value
(pricing risk), and the risk that the price or value of the investment fluctuates significantly over short periods of time (volatility risk). The value of derivatives may be influenced by a variety of factors, including national and international
political and economic developments. Potential changes to the regulation of the derivatives markets may make derivatives more costly, may limit the market for derivatives, or may otherwise adversely affect the value or performance of
derivatives.</FONT></DIV> <DIV style="color:#003C78;font-family:Arial;font-size:10pt;font-style:Normal;font-weight:bold;line-height:12pt;margin-top:4pt;text-align:left;text-decoration:none;text-transform:none;">Derivatives Risk &#8211; Futures
Contracts Risk. <FONT style="font-weight:Normal;">A futures contract is an exchange-traded derivative transaction between two parties in which a buyer (holding the &#8220;long&#8221; position) agrees to pay a fixed price (or rate) at a specified
future date for delivery of an underlying reference from a seller (holding the &#8220;short&#8221; position). The seller hopes that the market price on the delivery date is less than the agreed upon price, while the buyer hopes for the contrary.

illiquid. Futures exchanges may limit fluctuations in futures contract prices by imposing a maximum permissible daily price movement. The Fund may be disadvantaged if it is prohibited from executing a trade outside the daily permissible price
movement. At or prior to maturity of a futures contract, the Fund may enter into an offsetting contract and may incur a loss to the extent there has been adverse movement in futures contract prices. The liquidity of the futures markets depends on
participants entering into offsetting transactions rather than making or taking delivery. To the extent participants make or take delivery, liquidity in the futures market could be reduced. Positions in futures contracts may be closed out only on
the exchange on which they were entered into or through a linked exchange, and no secondary market exists for such contracts. Futures positions are marked to market each day and variation margin payment must be paid to or by the Fund. Because of the
low margin deposits normally required in futures trading, it is possible that the Fund may employ a high degree of leverage in the portfolio. As a result, a relatively small price movement in a futures contract may result in substantial losses to
the Fund, exceeding the amount of the margin paid. For certain types of futures contracts, losses are potentially unlimited. Futures markets are highly volatile and the use of futures may increase the volatility of the Fund&#8217;s NAV. Futures
contracts executed (if any) on foreign exchanges may not provide the same protection as U.S. exchanges. Futures contracts can increase the Fund&#8217;s risk exposure to underlying references and their attendant risks, such as credit risk, market
risk, foreign currency risk and interest rate risk, while also exposing the Fund to correlation risk, counterparty risk, hedging risk, inflation risk, leverage risk, liquidity risk, pricing risk and volatility risk.</DIV>

Securities Risk.<FONT style="font-weight:Normal;"> Securities issued by foreign governments or companies in emerging market countries,&#160;such as&#160;China, Russia and certain countries in Eastern Europe, the Middle East, Asia, Latin America or
Africa, are more likely to have greater exposure to the risks of investing in foreign securities that are described in Foreign Securities Risk. In addition, emerging market countries are more likely to experience instability resulting, for example,
from rapid changes or developments in social, political, economic or other conditions. Their economies are usually less mature and their securities markets are typically less developed with more limited trading activity (</FONT><FONT
 style="font-style:italic;font-weight:Normal;">i.e.</FONT><FONT style="font-weight:Normal;">, lower trading volumes and less liquidity) than more developed countries. Emerging market securities tend to be more volatile than securities in more
developed markets. Many emerging market countries are heavily dependent on international trade and have fewer trading partners, which makes them more sensitive to world commodity prices and economic downturns in other countries. Some emerging market
countries have a higher risk of currency devaluations, and some of these countries may experience periods of high inflation or rapid changes in inflation rates and may have hostile relations with other countries.</FONT></DIV>

Investments in or exposure to foreign securities involve certain risks not associated with investments in or exposure to securities of U.S. companies. For example, foreign markets can be extremely volatile. Foreign securities may also be less
liquid, making them more difficult to trade, than securities of U.S. companies so that the Fund may, at times, be unable to sell foreign securities at desirable times or prices. Brokerage commissions, custodial costs and other fees are also
generally higher for foreign securities. The Fund may have limited or no legal recourse in the event of default with respect to certain foreign securities, including those issued by foreign governments. In addition, foreign governments may impose
withholding or other taxes on the Fund&#8217;s income, capital gains or proceeds from the disposition of foreign securities, which could reduce the Fund&#8217;s return on such securities. In some cases, such withholding or other taxes could
potentially be confiscatory. Other risks include: possible delays in the settlement of transactions or in the payment of income; generally less publicly available information about foreign companies; the impact of economic, political, social,
diplomatic or other conditions or events (including, for example, military confrontations, war, terrorism and disease/virus outbreaks and epidemics), possible seizure, expropriation or nationalization of a company or its assets or the assets of a
particular investor or category of investors; accounting, auditing and financial reporting standards that may be less comprehensive and stringent than those applicable to domestic companies; the imposition of economic and other sanctions against a
particular foreign country, its nationals or industries or businesses within the country; and the generally less stringent standard of care to which local agents may be held in the local markets. In addition, it may be difficult to obtain reliable
information</FONT></DIV> </DIV> <DIV style="margin-top:22pt;width:91.43%;" type="Block"> <DIV style="text-align:right;">

Governments or trade groups may compel local agents to hold securities in designated depositories that are not subject to independent evaluation. The less developed a country&#8217;s securities market is, the greater the level of risks. The risks
posed by sanctions against a particular foreign country, its nationals or industries or businesses within the country may be heightened to the extent the Fund invests significantly in the affected country or region or in issuers from the affected
country that depend on global markets. Additionally, investments in certain countries may subject the Fund to a number of tax rules, the application of which may be uncertain. Countries may amend or revise their existing tax laws, regulations and/or
procedures in the future, possibly with retroactive effect. Changes in or uncertainties regarding the laws, regulations or procedures of a country could reduce the after-tax profits of the Fund, directly or indirectly, including by reducing the
after-tax profits of companies located in such countries in which the Fund invests, or result in unexpected tax liabilities for the Fund. The performance of the Fund may also be negatively affected by fluctuations in a foreign currency's strength or
weakness relative to the U.S. dollar, particularly&#160;to the extent&#160;the Fund invests a significant percentage of its assets in foreign securities or other assets denominated in currencies other than the U.S. dollar. Currency rates in foreign
countries may fluctuate significantly over short or long periods of time for a number of reasons, including changes in interest rates, imposition of currency exchange controls and economic or political developments in the U.S. or abroad. The Fund
may also incur currency conversion costs when converting foreign currencies into U.S. dollars and vice versa.</DIV>

Trading&#160;Risk.<FONT style="font-weight:Normal;">&#160;The portfolio managers may actively and frequently trade investments in the Fund's portfolio to carry out its investment strategies. Frequent trading of investments increases the possibility
that the Fund, as relevant, will realize taxable capital gains (including short-term capital gains, which are generally taxable to shareholders at higher rates than long-term capital gains for U.S. federal income tax purposes), which could reduce
the Fund's after-tax return. Frequent trading can also mean higher brokerage and other transaction costs, which could reduce the Fund's return. The trading costs and tax effects associated with portfolio turnover may adversely affect the
Fund&#8217;s performance.</FONT></DIV> <DIV style="color:#003C78;font-family:Arial;font-size:10pt;font-style:Normal;font-weight:bold;line-height:12pt;margin-top:4pt;text-align:left;text-decoration:none;text-transform:none;">High-Yield Investments
Risk.<FONT style="font-weight:Normal;"> Securities and other debt instruments held by the Fund that are rated below investment grade (commonly called &#8220;high-yield&#8221; or &#8220;junk&#8221; bonds) and unrated debt instruments of comparable
quality tend to be more sensitive to credit risk than higher-rated debt instruments and may experience greater price fluctuations in response to perceived changes in the ability of the issuing entity or obligor to pay interest and principal when due
than to changes in interest rates. These investments are generally more likely to experience a default than higher-rated debt instruments. High-yield debt instruments are considered to be predominantly speculative with respect to the issuer&#8217;s
capacity to pay interest and repay principal. These debt instruments typically pay a premium &#8211; a higher interest rate or yield &#8211; because of the increased risk of loss, including default. High-yield debt instruments may require a greater
degree of judgment to establish a price, may be difficult to sell at the time and price the Fund desires, may carry high transaction costs, and also are generally less liquid than higher-rated debt instruments. The ratings provided by third party
rating agencies are based on analyses by these ratings agencies of the credit quality of the debt instruments and may not take into account every risk related to whether interest or principal will be timely repaid. In adverse economic and other
circumstances, issuers of lower-rated debt instruments are more likely to have difficulty making principal and interest payments than issuers of higher-rated debt instruments.</FONT></DIV>
<DIV style="color:#003C78;font-family:Arial;font-size:10pt;font-style:Normal;font-weight:bold;line-height:12pt;margin-top:4pt;text-align:left;text-decoration:none;text-transform:none;">Interest Rate Risk.<FONT style="font-weight:Normal;"> Interest
rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes
in the value of a debt instrument usually will not affect the amount of income the Fund receives from it but will generally affect the value of your investment in the Fund. Changes in interest rates may also affect the liquidity of the Fund&#8217;s
investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. Interest rate declines also may increase prepayments of debt obligations, which, in
turn, would increase prepayment risk (the risk that the Fund will have to reinvest the money received in securities that have lower yields). Very low or negative interest rates may prevent the Fund from generating positive returns and may increase
the risk that, if followed by rising interest rates, the Fund&#8217;s performance will be negatively impacted. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and
central banking authorities can result in increases in interest rates. Such actions may negatively affect the value of debt instruments held by the Fund, resulting in a</FONT></DIV> </DIV> <DIV style="margin-top:22pt;width:91.43%;" type="Block">

Underperformance of an issuer may be caused by poor management decisions, competitive pressures, breakthroughs in technology, reliance on suppliers, labor problems or shortages, corporate restructurings, fraudulent disclosures, natural disasters,
military confrontations, war, terrorism, disease/virus outbreaks, epidemics or other events, conditions and factors which may impair the value of an investment in the Fund&#160;and could result in increased premiums or discounts to the Fund&#8217;s
net asset value.</FONT></DIV> <DIV style="color:#003C78;font-family:Arial;font-size:10pt;font-style:italic;font-weight:Normal;line-height:12pt;margin-top:4pt;text-align:left;text-decoration:none;text-transform:none;">Large-Cap Stock Risk.<FONT
 style="font-style:Normal;"> Investments in larger, more established companies (larger companies) may involve certain risks associated with their larger size. For instance, larger companies may be less able to respond quickly to new competitive
challenges, such as changes in consumer tastes or innovation from smaller competitors. Also, larger companies are sometimes less able to achieve as high growth rates as successful smaller companies, especially during extended periods of economic
expansion.</FONT></DIV> <DIV style="color:#003C78;font-family:Arial;font-size:10pt;font-style:Normal;font-weight:bold;line-height:12pt;margin-top:4pt;text-align:left;text-decoration:none;text-transform:none;">Leverage Risk<FONT
 style="font-weight:Normal;">. Senior securities issued or money borrowed to raise funds for investment have a prior fixed dollar claim on the Fund&#8217;s assets and income. Any gain in the value of securities purchased or income received in excess
of the cost of the amount borrowed or interest or dividends payable causes the net asset value of the Fund&#8217;s Common Stock or the income available to it to increase more than otherwise would be the case. Conversely, any decline in the value of
securities purchased or income received on them that is less than the asset or income claims of the senior securities or cost of borrowed money causes the net asset value of the Common Stock or income available to it to decline more sharply than
would be the case if there were no prior claim. Funds obtained through senior securities or borrowings thus create investment opportunity, but they also increase exposure to risk. This influence ordinarily is called &#8220;leverage.&#8221; As of
February 29, 2020, the only senior securities of the Fund outstanding were 752,740 shares of its Preferred Stock, $50 par value. The dividend rate as of February 29, 2020 on the Preferred Stock was $2.50 per annum payable quarterly. Based on the net
asset value of the Fund&#8217;s Common Stock on February 29, 2020, the Fund&#8217;s portfolio requires an annual return of 0.12% in order to cover dividend payments on the Preferred Stock. For a description of such payments, see </FONT><FONT

Common Stockholders, including the greater likelihood of higher volatility of the Fund&#8217;s return, its net asset value and the market price of the Fund&#8217;s Common Stock. Changes in the value of the Fund&#8217;s total assets will have a
disproportionate effect on the net asset value per share of Common Stock because of the Fund&#8217;s leveraged assets. For example, if the Fund was leveraged equal to 50% of the Fund&#8217;s Common Stock equity, it would show an approximately 1.5%
increase or decline in net asset value for each 1% increase or decline in the value of its total assets. An additional risk of leverage is that the cost of the leverage plus applicable Fund expenses may exceed the return on the transactions
undertaken with the proceeds of the leverage, thereby diminishing rather than enhancing the return to the Fund&#8217;s Common Stockholders. These risks generally would make the Fund&#8217;s return to Common Stockholders more volatile. The Fund also
may be required to sell investments in order to make interest payments on borrowings used for leverage when it may be disadvantageous to do so. Because the fees received by the Investment Manager are based on the net assets of the Fund

regulatory, market, economic or social developments affecting the relevant market(s) more generally. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or fixed income markets may negatively affect many issuers,
which could adversely affect the Fund, including causing difficulty in assigning prices to hard-to-value assets in thinly traded and closed markets, significant redemptions and operational challenges. Global economies and financial markets are
increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. These risks may be magnified if certain events or developments
adversely interrupt the global supply chain; in these and other circumstances, such risks might affect companies worldwide. As a result, local, regional or global events such as terrorism, war, natural disasters, disease/virus outbreaks and
epidemics or other public health issues, recessions, depressions or other events &#8211; or the potential for such events &#8211; could have a significant negative impact on global economic and market conditions&#160;and could result in increased

has become a pandemic that has resulted in, and may continue to result in, significant global economic and societal disruption and market volatility due to disruptions in market access, resource availability, facilities operations, imposition of
tariffs, export controls and supply chain disruption, among others. Such disruptions may be caused, or exacerbated by, quarantines and travel restrictions, workforce displacement and loss in human and other resources. The uncertainty surrounding the
magnitude, duration, reach, costs and effects of the global pandemic, as well as actions that have been or could be taken by governmental authorities or other third parties, present unknowns that are yet to unfold. The impacts, as well as the
uncertainty over impacts to come, of COVID-19 &#8211; and any other infectious illness outbreaks, epidemics and pandemics that may arise in the future &#8211; could negatively affect global economies and markets in ways that cannot necessarily be
foreseen. In addition, the impact of infectious illness outbreaks and epidemics in emerging market countries may be greater due to generally less established healthcare systems, governments and financial markets. Public health crises caused by the
COVID-19 outbreak may exacerbate other pre-existing political, social and economic risks in certain countries or globally. The disruptions caused by COVID-19 could prevent the Fund from executing advantageous investment decisions in a timely manner
and negatively impact the Fund&#8217;s ability to achieve its investment objective. Any such event(s) could have a significant adverse impact on the value and risk profile of the Fund.</DIV>

Preferred stock is a type of stock that may pay dividends at a different rate than common stock of the same issuer, if at all, and that has preference over common stock in the payment of dividends and the liquidation of assets. Preferred stock does
not ordinarily carry voting rights. The price of a preferred stock is generally determined by earnings, type of products or services, projected growth rates, experience of management, liquidity, and general market conditions of the markets on which
the stock trades. The most significant risks associated with investments in preferred stock include issuer risk, market risk and interest rate risk (the risk of losses attributable to changes in interest rates).</FONT></DIV>

Quantitative models used by the Fund may not effectively identify purchases and sales of Fund investments and may cause the Fund to underperform other investment strategies for short or long periods of time. Performance will depend upon the quality
and accuracy of the assumptions, theories and framework upon which a quantitative model is based. The success of a quantitative model will depend upon the model&#8217;s accurate reflection of market conditions, with proper adjustments as market
conditions change over time. Adjustments, or lack of adjustments, to the models, including as conditions change, as well as any errors or imperfections in the models, could adversely affect Fund performance. Quantitative model performance depends
upon the quality of its design and effective execution under actual market conditions. Even a well-designed quantitative model cannot be expected to perform well in all market conditions or across all time intervals. Quantitative models may
underperform in certain market environments including stressed or volatile market conditions. Effective execution may depend, in part, upon subjective selection and application of factors and data inputs used by the quantitative model. Discretion

 style="font-weight:Normal;"> The Fund may invest in privately placed and other securities or instruments exempt from SEC registration (collectively &#8220;private placements&#8221;), subject to certain regulatory restrictions. In the U.S. market,
private placements are typically sold only to qualified institutional buyers, or qualified purchasers, as applicable. An insufficient number of buyers interested in purchasing private placements at a particular time could adversely affect the
marketability of such investments and the Fund might be unable to dispose of them promptly or at reasonable prices, subjecting the Fund to liquidity risk (the risk that it may not be possible for the Fund to liquidate the instrument at an
advantageous time or price). The Fund&#8217;s holdings of private placements may increase the level of Fund illiquidity if eligible buyers are unable or unwilling to purchase them at a particular time. The Fund may also have to bear the expense of
registering the securities for resale and the risk of substantial delays in effecting the registration. Additionally, the purchase price and subsequent valuation of private placements typically reflect a discount, which may be significant, from the
market price of comparable securities for which a more liquid market exists. Issuers of Rule 144A eligible securities are required to furnish information to potential investors upon request. However, the required disclosure is much less extensive
than that required of public companies and is not publicly available since the offering information is not filed with the SEC. Further, issuers of Rule 144A eligible securities can require recipients of the offering information (such as the Fund) to
agree contractually to keep the information confidential, which could also adversely affect the Fund&#8217;s ability to dispose of the security.</FONT></DIV>

Fund may have a significant portion of its assets invested in securities of companies conducting business within one or more economic sectors, including the information technology sector. Companies in the&#160;same sector may be similarly affected
by economic, regulatory, political or market events or conditions, which may make the Fund more vulnerable to unfavorable developments in that sector than funds that invest more broadly. Generally, the more broadly the Fund invests, the more it
spreads risk and potentially reduces the risks of loss and volatility.</FONT></DIV>

 style="font-style:Normal;">The Fund may be more susceptible to the particular risks that may affect companies in the information technology sector than if it were invested in a wider variety of companies in unrelated sectors. Companies in the
information technology sector are subject to certain risks, including the risk that new services, equipment or technologies will not be accepted by consumers and businesses or will become rapidly obsolete. Performance of such companies may be
affected by factors including obtaining and protecting patents (or the failure to do so) and significant competitive pressures, including aggressive pricing of their products or services, new market entrants, competition for market share and short
product cycles due to an accelerated rate of technological developments. Such competitive pressures may lead to limited earnings and/or falling profit margins. As a result, the value of their securities may fall or fail to rise. In addition, many
information technology sector companies have limited operating histories and prices of these companies&#8217; securities historically have been more volatile than other securities, especially over the short term.</FONT></DIV>

Franklin Street, Boston, MA 02110 and serves as investment adviser&#160;and administrator to the Columbia Funds. The Investment Manager is a registered investment adviser and a wholly-owned subsidiary of Ameriprise Financial. The Investment
Manager&#8217;s management experience covers all major asset classes, including equity securities, debt instruments and money market instruments. In addition to serving as an investment adviser to traditional mutual funds, exchange-traded funds and
closed-end funds, the Investment Manager acts as an investment adviser for itself, its affiliates, individuals, corporations, retirement plans, private investment companies and financial intermediaries.</DIV>

manages the day-to-day operations of the Fund, determining what securities and other investments the Fund should buy or sell and executing portfolio transactions. The Investment Manager may use the research and other capabilities of its affiliates
and third parties in managing the Fund&#8217;s investments. The Investment Manager is also responsible for overseeing the administrative operations of the Fund, including the general supervision of the Fund&#8217;s operations, the coordination of

services, which include investment advisory services and administrative services. The fee is calculated as a percentage of the daily net assets of the Fund and is paid monthly. For the Fund&#8217;s most recent fiscal year,&#160;management services
fees paid to the Investment Manager by the Fund amounted to 0.42% of average daily net assets of the Fund's Common Stock. The management services fee is equal to 0.415% of the Fund&#8217;s net assets (which includes assets attributable to the
Fund&#8217;s Common Stock and Preferred Stock) on the first $500 million, gradually reducing to 0.385% as assets increase.</DIV>

paid on the Preferred Stock for all past quarterly periods and have been provided for the current quarterly period, and (iii) such provisions have been made for the purchase or for the redemption (at a price of $55 per share) of the Preferred Stock

Notwithstanding any provision of law requiring any action to be taken or authorized by the affirmative vote of the holders of a designated portion of all the shares or of the shares of each class, such action shall be effective if taken or
authorized by the affirmative vote of a majority of the aggregate number of the votes entitled to vote thereon, except that a class vote of Preferred Stockholders is also required to approve certain actions adversely affecting their rights. Any

consolidation of the Fund (in which the Fund is not the surviving corporation) with (a) an open-end investment company or (b) a closed-end investment company, unless such closed-end investment company&#8217;s articles of incorporation require a
two-thirds or greater proportion of the votes entitled to be cast by such company&#8217;s stock to approve the types of transactions covered by clauses (i) through (iv) of this paragraph; (iii) the sale of all or substantially all of the assets of
the Fund to any person (as such term is defined in the 1940 Act); or (iv) any amendment of the charter of this Fund which makes any class of the Fund&#8217;s stock a redeemable security (as such term is defined in the 1940 Act) or reduces the

The Fund&#8217;s charter and Warrant certificates provide that each Warrant represents the right during an unlimited time to purchase one share of Common Stock at a price of $22.50 per share, subject to increase in the number of shares purchasable
and adjustment of the price payable pursuant to provisions of the charter requiring such adjustments whenever the Fund issues any shares of Common Stock at a price less than the Warrant purchase price in effect immediately prior to issue. Each
Warrant presently entitles the holder to purchase 24.19 shares of Common Stock at $0.93 per share.</DIV>

Fractional shares of Common Stock are not issued upon the exercise of Warrants. In lieu thereof, the Fund issues scrip certificates representing corresponding fractions of the right to receive a full share of Common Stock if exchanged by the end of
the second calendar year following issuance or of the proceeds of the sale of a full share if surrendered during the next four years thereafter.</DIV>

Common Stock in amounts representing substantially all of the net investment income earned each year by the Fund. Payments on the Preferred Stock are in a fixed amount, but payments on the Common Stock vary in amount, depending on investment income
received and expenses of operation. In addition, substantially all of any taxable net gain realized on investments is paid to Common Stockholders at least annually.</DIV>

(i.e., Direct-at-Fund Accounts, which are serviced by the Service Agent), unless the Service Agent is otherwise instructed by you, distributions on the Common Stock are paid in book shares of Common Stock which are entered in your Fund account as
&#8220;book credits.&#8221; You may also elect to receive distributions 75% in shares and 25% in cash, 50% in shares and 50% in cash, or 100% in cash. Any such election must be received by the Service Agent by the record date for a distribution. If
you hold your shares of Common Stock through a financial intermediary (such as a broker), you should contact the financial intermediary to discuss your reinvestment and distribution options, as they may be different than as described above for
accounts held directly with the Fund. A distribution is treated in the same manner for income tax purposes whether you receive it in cash or partly or entirely in shares. Elections received after a record date for a distribution will be effective in
respect of the next distribution. Shares issued to you in respect of distributions will be at a price equal to the lower of: (i) the closing sale or bid price, plus applicable commission, of the Common Stock on the New York Stock Exchange on the
ex-dividend date or (ii) the greater of NAV per share of the Common Stock and 95% of the closing price of the Common Stock on the New York Stock Exchange on the ex-dividend date (without adjustment for the exercise of Warrants remaining
outstanding). The issuance of Common Stock at less than NAV per share will dilute the NAV of all Common Stock outstanding at that time. Distributions received by you will have the effect of reducing the NAV of the shares of the Fund by the amount of
such distributions. If the NAV of shares is reduced below your cost by a distribution, the distribution will be taxable as described below even though it is in effect a return of capital.</DIV>

and the Board&#8217;s right to suspend, modify or terminate the distribution policy described below in the event the Board determines that such action would be in the best interests of the Fund. In addition, distributions will be made only when, as
and if approved and declared and after paying dividends on the Preferred Stock and interest and required principal payments on borrowings, if any.</DIV> </DIV> <DIV style="margin-top:44pt;width:91.43%;" type="Block"> <DIV style="text-align:left;">

Fund, subject to appropriate approval, intends to make quarterly distributions to Common Stockholders that are approximately equal to net investment income, less dividends payable on the Fund&#8217;s Preferred Stock. Capital gains, when available,
are generally distributed to Common Stockholders along with the last income dividend of the calendar year. If capital gains are earned in November or December of a calendar year, they will be distributed in the following year. Dividends and other
distributions to Stockholders are recorded on ex-dividend dates.</DIV>
<DIV style="color:#003C78;font-family:Arial;font-size:10pt;font-style:Normal;font-weight:bold;line-height:12pt;margin-top:6pt;text-align:left;text-decoration:none;text-transform:none;">Taxes</DIV>

treated as a regulated investment company under the Internal Revenue Code. As a regulated investment company, the Fund will generally not be subject to federal income taxes on its investment company taxable income and net capital gains realized
during the year, if any, which it distributes to stockholders, provided that at least 90% of its investment company taxable income (which includes net short-term capital gains) is distributed to stockholders each year, among other
requirements.</DIV> <DIV style="color:#003C78;font-family:Arial;font-size:10pt;font-style:Normal;font-weight:Normal;line-height:12pt;margin-top:4pt;text-align:left;text-decoration:none;text-transform:none;">Qualification as a regulated investment
company does not involve governmental supervision of management or investment practices or policies. Investors should consult their own advisors for a complete understanding of the requirements the Fund must meet to qualify for such treatment. The
information set forth below relates solely to certain U.S. Federal tax matters applicable to the Fund and its U.S. stockholders, and assumes that the Fund qualifies as a regulated investment company.</DIV>
<DIV style="color:#003C78;font-family:Arial;font-size:10pt;font-style:Normal;font-weight:Normal;line-height:12pt;margin-top:4pt;text-align:left;text-decoration:none;text-transform:none;">If for any year the Fund does not qualify as a regulated
investment company, all of its taxable income (including its net capital gain) will be subject to tax at the corporate tax rate without any deduction for distributions to stockholders. Such distributions would generally be taxable to the
stockholders as qualified dividend income and generally would be eligible for the dividends received deduction in the case of corporate stockholders.</DIV>
<DIV style="color:#003C78;font-family:Arial;font-size:10pt;font-style:Normal;font-weight:Normal;line-height:12pt;margin-top:4pt;text-align:left;text-decoration:none;text-transform:none;">Dividends on Common Stock from the Fund&#8217;s ordinary
income and net short-term capital gains are taxable to stockholders as ordinary income, whether received in cash or invested in additional shares. Dividends on Common Stock that the Fund reports as qualified dividend income will be taxed at a
reduced rate to individuals (0%, 15%, or 20%) if the stockholder meets certain holding period requirements. Qualified dividend income is, in general, dividend income from taxable domestic corporations and certain foreign corporations (generally
foreign corporations incorporated in a possession of the United States or eligible for the benefits of a comprehensive tax treaty with the United States that meets certain requirements, or if the stock with respect to which such dividend is paid is
readily tradable on an established securities market in the United States). The amount of dividends that may be designated as &#8220;qualified dividend income&#8221; by the Fund will generally be limited to the aggregate of the eligible dividends
received by the Fund. In addition, the Fund must meet certain holding period requirements with respect to the shares on which the Fund received the eligible dividends, and the non-corporate U.S. stockholder must meet certain holding period
requirements with respect to the Fund&#8217;s shares.</DIV>
<DIV style="color:#003C78;font-family:Arial;font-size:10pt;font-style:Normal;font-weight:Normal;line-height:12pt;margin-top:4pt;text-align:left;text-decoration:none;text-transform:none;">Distributions of net capital gains (i.e., the excess of net
long-term capital gains over any net short-term capital losses) are taxable to stockholders as long-term capital gains, whether received in cash or invested in additional shares, regardless of how long stockholders held their shares. Individual
stockholders will be subject to federal income tax on distributions reported by the Fund as capital gains dividends at preferential rates (0%, 15%, or 20%). Net capital gain of a corporate stockholder is taxed at the same rate as ordinary
income.</DIV> <DIV style="color:#003C78;font-family:Arial;font-size:10pt;font-style:Normal;font-weight:Normal;line-height:12pt;margin-top:4pt;text-align:left;text-decoration:none;text-transform:none;">At December 31, 2019, the Fund had no capital

calendar year, payable to stockholders of record on a specified date in such a month and paid in the following January will be treated as having been paid by the Fund and received by each stockholder on December 31 of such calendar year. Under this
rule, therefore, stockholders may be taxed in one year on dividends actually received (or reinvested) in January of the following year.</DIV>
<DIV style="color:#003C78;font-family:Arial;font-size:10pt;font-style:Normal;font-weight:Normal;line-height:12pt;margin-top:4pt;text-align:left;text-decoration:none;text-transform:none;">Distributions of Common Stock will generally be treated as if
the stockholder received cash equivalent to the value of such Common Stock. A stockholder will have a tax basis in the distributed shares of Common Stock equal to such amount and a stockholder&#8217;s holding period with respect to such Common Stock
will begin the day following the distribution date for the Common Stock.</DIV> </DIV> <DIV style="margin-top:32pt;width:91.43%;" type="Block"> <DIV style="text-align:right;">

(provided you are not a dealer in securities and hold the Common Stock as a capital asset) will generally be treated as a long-term capital gain or loss if you held your shares for more than one year and as a short-term capital gain or loss if you
held your shares for one year or less. Long-term capital gain of a non-corporate U.S. stockholder is generally taxed at preferential rates (0%, 15%, or 20%). Net capital gain of a corporate stockholder is taxed at the same rate as ordinary income.
However, if shares on which a capital gain distribution has been received are subsequently sold and such shares have been held for six months or less (after taking into account certain transactions that may affect the holding period of the shares),
any loss realized will be treated as long-term capital loss to the extent of the long-term capital gain distribution. No loss will be allowed on the sale or other disposition of shares of Common Stock if, within a period beginning 30 days before the
date of such sale or disposition and ending 30 days after such date, you acquire (such as through the Fund&#8217;s Automatic Dividend Investment Plan or Cash Purchase Plan), or enter into a contract or option to acquire, additional shares of the
Fund or securities that are substantially identical to the Common Stock.</DIV>
<DIV style="color:#003C78;font-family:Arial;font-size:10pt;font-style:Normal;font-weight:Normal;line-height:12pt;margin-top:4pt;text-align:left;text-decoration:none;text-transform:none;">The repurchase of shares of Common Stock by the Fund generally
will be a taxable transaction for federal income tax purposes, either as a sale as described above or, under certain circumstances, as a dividend. A repurchase of shares of Common Stock generally will be treated as a sale if the receipt of cash by
the stockholder results in a &#8220;complete redemption&#8221; of the stockholder&#8217;s interest in the Fund or is &#8220;substantially disproportionate&#8221; or &#8220;not essentially equivalent to a dividend&#8221; with respect to the
stockholder. In determining whether any of these tests have been met, shares actually owned and shares considered to be owned by the stockholder by reason of certain constructive ownership rules generally must be taken into account.</DIV>
<DIV style="color:#003C78;font-family:Arial;font-size:10pt;font-style:Normal;font-weight:Normal;line-height:12pt;margin-top:4pt;text-align:left;text-decoration:none;text-transform:none;">If a repurchase of shares of Common Stock by the Fund is not
treated as a sale, it will be taxable to the stockholder as a dividend to the extent of such stockholder&#8217;s allocable share of the Fund&#8217;s current and accumulated earnings and profits. Any proceeds in excess of the amount taxable as a
dividend would constitute a nontaxable return of capital (to the extent of the stockholder&#8217;s adjusted tax basis in the shares of Common Stock repurchased), and any amount in excess of the stockholder&#8217;s adjusted tax basis would constitute
taxable gain. Any remaining tax basis in the shares of Common Stock repurchased by the Fund will be transferred to any remaining shares of Common Stock held by such stockholder.</DIV>
<DIV style="color:#003C78;font-family:Arial;font-size:10pt;font-style:Normal;font-weight:Normal;line-height:12pt;margin-top:4pt;text-align:left;text-decoration:none;text-transform:none;">Proposed regulations provide that a fund investing in real
estate investment trusts (REITs) that designate qualified REIT dividends may designate section 199A dividends in written statements to Fund stockholders. Non-corporate Fund stockholders may be able to deduct 20% of a fund&#8217;s designated section
199A dividends (if any). There is no assurance that the Fund will designate section 199A dividends, even if it is eligible to do so.</DIV>
<DIV style="color:#003C78;font-family:Arial;font-size:10pt;font-style:Normal;font-weight:Normal;line-height:12pt;margin-top:4pt;text-align:left;text-decoration:none;text-transform:none;">Certain high-income individuals (as well as estates and
trusts) are subject to a 3.8% tax on net investment income. For individuals, the 3.8% tax applies to the lesser of (1) the amount (if any) by which the taxpayer&#8217;s modified adjusted gross income exceeds certain threshold amounts or (2) the
taxpayer&#8217;s &#8220;net investment income.&#8221; Net investment income generally includes for this purpose dividends, including any capital gain dividends, paid by the Fund, and net capital grains recognized on the sale or disposition of Common
Stock.</DIV> <DIV style="color:#003C78;font-family:Arial;font-size:10pt;font-style:Normal;font-weight:Normal;line-height:12pt;margin-top:4pt;text-align:left;text-decoration:none;text-transform:none;">The Fund is required by federal law to withhold
tax at the rate of 24% of taxable distributions and repurchase proceeds paid to you (including amounts paid to you in additional shares of Common Stock) if: you have not provided a correct taxpayer identification number (TIN) or have not certified
to the Fund that withholding does not apply; the Internal Revenue Service (IRS) has notified the Fund that the TIN provided is incorrect according to its records; or the IRS informs the Fund that you are otherwise subject to backup withholding. Any
amounts withheld may be refunded or credited against your U.S. federal income tax liability, if any, provided the required information is furnished to the IRS on a timely basis.</DIV>
<DIV style="color:#003C78;font-family:Arial;font-size:10pt;font-style:Normal;font-weight:Normal;line-height:12pt;margin-top:4pt;text-align:left;text-decoration:none;text-transform:none;">The Fund is subject to a 4% nondeductible excise tax on
amounts required to be paid but not distributed under a prescribed formula. The formula requires payment to stockholders during a calendar year of distributions representing at least 98% of the Fund&#8217;s ordinary income for the calendar year, at
least 98.2% of its net capital gain income realized during the one-year period ending on October 31 during such year, and all ordinary income and net capital gain income for prior years that was not previously distributed. The Fund intends to make
sufficient distributions or deemed distributions of its ordinary income and net capital gain income prior to the end of each calendar year to avoid liability for the excise tax, but there is no assurance that the Fund will be able to do so.</DIV>

Stock Exchange (NYSE) is open. A business day typically ends at the close of regular trading on the NYSE, usually at 4:00 p.m. Eastern time. If the NYSE is scheduled to close early, the business day will be considered to end as of the time of the
NYSE&#8217;s scheduled close. The Fund will not treat an intraday unscheduled disruption in NYSE trading or an intraday unscheduled closing as a close of regular trading on the NYSE for these purposes and will price its shares as of the regularly
scheduled closing time for that day (typically, 4:00 p.m. Eastern time). Notwithstanding the foregoing, the NAV of Fund shares may be determined at such other time or times (in addition to or in lieu of the time set forth above) as the Fund&#8217;s
Board may approve or ratify. On holidays and other days when the NYSE is closed, the Fund&#8217;s NAV is not calculated and the Fund does not accept buy or sell orders. However, the value of the Fund&#8217;s assets may still be affected on such days
to the extent that the Fund holds foreign securities that trade on days that foreign securities markets are open.</DIV> </DIV>

quotations reported on stock exchanges and other securities markets around the world. If an equity security is listed on a national exchange, the security is valued at the closing price or, if the closing price is not readily available, the mean of
the closing bid and asked prices. Certain equity securities, debt securities and other assets are valued differently. For instance, bank loans trading in the secondary market are valued primarily on the basis of indicative bids, fixed income
investments maturing in 60 days or less are valued primarily using the amortized cost method, unless this methodology results in a valuation that does not approximate the market value of these securities, and those maturing in excess of 60 days are
valued primarily using a market-based price obtained from a pricing service, if available. Investments in open-end funds are valued at their published NAVs. Both market quotations and indicative bids are obtained from outside pricing services
approved and monitored pursuant to a policy approved by the Fund's Board.</DIV>
<DIV style="color:#003C78;font-family:Arial;font-size:10pt;font-style:Normal;font-weight:Normal;line-height:12pt;margin-top:4pt;text-align:left;text-decoration:none;text-transform:none;">If a market price is not readily available or is deemed not to
reflect market value, the Fund will determine the price of a portfolio security based on a determination of the security's fair value pursuant to a policy approved by the Fund&#8217;s Board. In addition, the Fund may use fair valuation to price
securities that trade on a foreign exchange when a significant event has occurred after the foreign exchange closes but before the time at which the Fund&#8217;s share price is calculated. Foreign exchanges typically close before the time at which
Fund share prices are calculated, and may be closed altogether on days when the Fund is open. Such significant events affecting a foreign security may include, but are not limited to: (1) corporate actions, earnings announcements, litigation or
other events impacting a single issuer; (2) governmental action that affects securities in one sector or country; (3) natural disasters or armed conflicts affecting a country or region; or (4) significant domestic or foreign market fluctuations. The
Fund uses various criteria, including an evaluation of U.S. market moves after the close of foreign markets, in determining whether a foreign security's market price is readily available and reflective of market value and, if not, the fair value of
the security. To the extent the Fund has significant holdings of small cap stocks, high-yield bonds, floating rate loans, or tax-exempt, foreign or other securities that may trade infrequently, fair valuation may be used more frequently than for
other funds.</DIV> </DIV> <DIV style="margin-top:34pt;width:91.43%;" type="Block"> <DIV style="text-align:left;">

arbitrage opportunities presented by the pricing of Fund shares. However, when the Fund uses fair valuation to price securities, it may value those securities higher or lower than another fund would have priced the security. Also, the use of fair
valuation may cause the Fund's performance to diverge to a greater degree from the performance of various benchmarks used to compare the Fund's performance because benchmarks generally do not use fair valuation techniques. Because of the judgment
involved in fair valuation decisions, there can be no assurance that the value ascribed to a particular security is accurate. The Fund has retained one or more independent fair valuation pricing services to assist in the fair valuation process for
foreign securities.</DIV> </DIV> <DIV style="margin-top:538pt;width:91.43%;" type="Block"> <DIV style="text-align:right;">

Direct-at-Fund Accounts, and confirms such account transactions to stockholders. To insure prompt delivery of checks, account statements and other information, you should notify the Service Agent immediately, in writing or over the phone, of any
address changes. If mail sent by the Fund or the Service Agent, including confirmations, statements or tax forms, is returned as undeliverable by the U.S. Postal Service, the Fund or the Service Agent will stop all mailings to your address of record
and any subsequent systematic purchases to your account will not be permitted until you provide a valid mailing address. If you elect to receive Fund income dividend distribution or capital gains distributions by check and your check is returned as
undeliverable by the U.S. Postal Service, the Fund or the Service Agent will reinvest the distribution check in your account to purchase additional shares of the Fund and all future distributions will be automatically reinvested until you provide a
valid mailing address. Reinvested distributions (i.e., purchases made under the Automatic Dividend Investment Plan) will receive the market offering price calculated on the date of the reinvestment. Purchase orders made under the Cash Purchase Plan
(including reinvestment of returned distribution checks as described above) are generally priced one time per week, typically each Wednesday, or the next available business day if the Exchange is not open for business on Wednesday; however, the
processing of Fund share purchase orders, including the exercise of Warrants to purchase shares of Common Stock, may be delayed in connection with regulatory requirements obligating the Fund to suspend the offering of Fund shares until this
prospectus is amended if, subsequent to the date of this prospectus, the Fund&#8217;s NAV declines more than ten percent from its NAV as of the date of this prospectus. You will not receive interest on amounts represented by uncashed distribution
checks.</DIV> <DIV style="color:#003C78;font-family:Arial;font-size:10pt;font-style:Normal;font-weight:Normal;line-height:12pt;margin-top:4pt;text-align:left;text-decoration:none;text-transform:none;">If you close your account, it is important that

should not sign the certificates and they should be sent by certified or registered mail. Return receipt is advisable; however, this may increase mailing time. We recommend using registered mail when returning outstanding certificates for 1.5% of
the current market value of the shares. The recommended insurance amount is based on the premium for a lost certificate bond in the event the certificate is lost in transit.</DIV>

delivery to a broker if you wish to sell shares. A certificate will be issued and sent to you on your written or telephone request to the Service Agent, usually within two business days of the receipt of your request. You should consider the time it

Exchange on the preceding trading day was higher than the NAV per share (without adjustment for the exercise of Warrants remaining outstanding). If on the date shares are issuable to stockholders making cash purchase investments under the Cash
Purchase Plan (the Issuance Date), shares previously purchased by the Fund are insufficient to satisfy cash purchase investments and on the last trading day immediately preceding the Issuance Date the closing sale or bid price of the Common Stock is
lower than or the same as the NAV per share, the Fund will continue to purchase shares until a number of shares sufficient to cover all investments by stockholders has been purchased or the closing sale or bid price of the Common Stock becomes
higher than the NAV, in which case the Fund will issue the necessary additional shares. If on the last trading date immediately preceding the Issuance Date, the closing sale or bid price of the Common Stock was higher than the NAV per share, and if
shares of the Common Stock previously purchased on the Exchange or elsewhere are insufficient to satisfy cash purchase investments, the Fund will issue the necessary additional shares from authorized but unissued shares of the Common Stock.</DIV>

on the ex-dividend date or Issuance Date or (2) the greater of the NAV per share of the Common Stock on such trading day (without adjustment for the exercise of Warrants remaining outstanding) and 95% of the closing sale or bid price of the Common
Stock on the Exchange on such trading day. The issuance of Common Stock at less than NAV per share will dilute the NAV of all Common Stock outstanding at that time. The Common Stock has historically been priced in the market at less than its NAV per

Fund from the purchases made under the Cash Purchase Plan will be added to its general funds and will be available for investment. The Investment Manager anticipates that investment of any proceeds, in accordance with the Fund&#8217;s investment
objective and policies, will take up to thirty days from their receipt by the Fund, depending on market conditions and the availability of appropriate securities, but in no event will such investment take longer than six months. Pending such
investment in accordance with the Fund&#8217;s objective and policies, the proceeds will be held in U.S. Government Securities (which term includes obligations of the United States Government, its agencies or instrumentalities) and other short-term
money market instruments as well as affiliated money market funds.</DIV> </DIV> <DIV style="margin-top:50pt;width:91.43%;" type="Block"> <DIV style="text-align:left;">

option to add to their investment with reinvested distributions from the Fund, and the Cash Purchase Plan provides stockholders with the option to add to their investment with cash purchases. You may participate in one or both of the Investment
Plans. Direct-at-Fund Account stockholders will automatically be enrolled in the reinvested distributions option under the Automatic Dividend Investment Plan, but must elect to participate in the cash purchase option under the Cash Purchase

The systematic withdrawal option is made available to Direct-at-Fund Account stockholders. The systematic withdrawal option enables you to receive fixed payments from your investment in the Fund&#8217;s Common Stock in any amount at specified
regular intervals. You may start a systematic withdrawal option under the Investment Plans if your shares of the Fund&#8217;s Common Stock have a market value of $5,000 or more. Shares must be held in your account as book credits. The Service Agent
will act for you, make payments to you in specified amounts on either the 1st or 15th day of each month, as designated by you, and maintain your account.</FONT></DIV>
<DIV style="color:#003C78;font-family:Arial;font-size:10pt;font-style:Normal;font-weight:Normal;line-height:12pt;margin-top:4pt;text-align:left;text-decoration:none;text-transform:none;">You may choose to receive your withdrawals via check or direct
deposit into your bank account. Payments under the systematic withdrawal option will be made by selling exactly enough full and fractional shares of Common Stock to cover the amount of the designated withdrawal. Sales may be made on the Exchange or
elsewhere. Payments from sales of shares will reduce the amount of capital at work and dividend earning ability, and ultimately may liquidate your investment in the Fund. You can cancel the systematic withdrawal option by giving the Fund 30
days&#8217; notice in writing or by calling the Service Agent at 800.345.6611, option 3. Sales of shares may result in gain or loss to you for income tax purposes. Please contact the Service Agent for further information on how to establish or
cancel the systematic withdrawal option on your account.</DIV>

proceeds for up to seven days. The Fund can also suspend sales and/or delay payment of sale proceeds in excess of seven days under certain circumstances, including when the Exchange is closed or trading thereon is restricted or during emergency or
other circumstances, including as determined by the SEC.</DIV>

received payment. Shares purchased by check or electronically by ACH when the purchase payment is not guaranteed will be considered in &#8220;good form&#8221; for sale only after they have been held in your account for 6 calendar days after the
trade date of the purchase (Collected Shares). If you request a sale for an amount that, based on the market price next calculated after your request is received, includes any shares that are not yet Collected Shares, the Fund will only process the
sale up to the amount of the value of Collected Shares available in your account. The sale of newly purchased Fund shares that are not Collected Shares will not be processed until such shares become Collected Shares (and therefore in &#8220;good
form&#8221;) and will then be priced by the Fund the next Wednesday, or the next available business day if the Exchange is not open for business on Wednesday. You must submit a new request if you wish to sell those shares that were not yet Collected
Shares at the time the original request was received by the Fund.</DIV> </DIV> <DIV style="margin-top:198pt;width:91.43%;" type="Block"> <DIV style="text-align:right;">
