TABLE OF CONTENTS

Prospectus Summary

This is only a summary. You should review the more detailed information elsewhere in this prospectus (“Prospectus”), in any related supplement to this Prospectus (each, a “Prospectus Supplement”), and in the Statement of Additional Information (the “SAI”) prior to making an investment in the Fund. See “Risk Factors.”

Summary of Fund Expenses

The purpose of the table below is to help you understand all fees and expenses that you, as a Common Shareholder, would bear directly or indirectly. In accordance with SEC requirements, the table below shows the Fund’s expenses as a percentage of its average net assets as of October 31, 2015, and not as a percentage of total assets. By showing expenses as a percentage of average net assets, expenses are not expressed as a percentage of all of the assets in which the Fund invests. The offering costs to be paid or reimbursed by the Fund are not included in the Annual Expenses table below. However, these expenses will be borne by Common Shareholders and may result in a reduction in the NAV of the Common Shares. See “Management of the Fund” and “Dividend Reinvestment Plan.” The table and example are based on the Fund’s capital structure as of October 31, 2015.

EXAMPLE

The following example illustrates the expenses that Common Shareholders would pay on a $1,000 investment in Common Shares, assuming (i) total annual expenses of 1.54% of net assets attributable to Common Shares in years 1 through 10; (ii) a 5% annual return; and (iii) all distributions are reinvested at NAV:

The above table and example and the assumption in the example of a 5% annual return are required by regulations of the SEC that are applicable to all investment companies; the assumed 5% annual return is not a prediction of, and does not represent, the projected or actual performance of the Fund’s Common Shares. For more complete descriptions of certain of the Fund’s costs and expenses, see “Management of the Fund.” In addition, while the example assumes reinvestment of all dividends and distributions at NAV, participants in the Fund’s dividend reinvestment plan may receive Common Shares purchased or issued at a price or value different from NAV. See

“Distribution Policy” and “Dividend Reinvestment Plan.” The example does not include sales load or estimated offering costs, which would cause the expenses shown in the example to increase.

The example should not be considered a representation of past or future expenses, and the Fund’s actual expenses may be greater or less than those shown. Moreover, the Fund’s actual rate of return may be greater or less than the hypothetical 5% return shown in the example.

Financial Highlights

This table details the financial performance of the Common Shares, including total return information showing how much an investment in the Fund has increased or decreased each period.

The financial statements of the Fund as of October 31, 2015 have been audited by PricewaterhouseCoopers LLP (“PwC”), the Fund’s independent registered public accounting firm. The report of PwC is included, along with the Fund’s financial statements, in the Fund’s annual report, which has been incorporated by reference into the SAI and is available upon request.

Market and Net Asset Value Information

The Fund’s currently outstanding Common Shares are listed on the New York Stock Exchange (“NYSE”) under the symbol “JHI” and commenced trading on the NYSE in 1971.

The Fund’s Common Shares have traded both at a premium and at a discount to its net asset value (“NAV”). The Fund cannot predict whether its shares will trade in the future at a premium or discount to NAV. The provisions of the 1940 Act generally require that the public offering price of common shares (less any underwriting commissions and discounts) must equal or exceed the NAV per share of a company’s common stock (calculated within 48 hours of pricing). The Fund’s issuance of Common Shares may have an adverse effect on prices in the secondary market for Common Shares by increasing the number of Common Shares available, which may put downward pressure on the market price for Common Shares. Shares of common stock of closed-end investment companies frequently trade at a discount from NAV. See “Risk Factors—General Risks—Market Discount Risk.”

The following table sets forth for each of the periods indicated the high and low closing market prices for Common Shares on the NYSE, and the corresponding NAV per share and the premium or discount to NAV per share at which the Fund’s Common Shares were trading as of such date. NAV is determined once daily as of the close of regular trading of the NYSE (typically 4:00 P.M., Eastern Time). See “Determination of Net Asset Value” for information as to the determination of the Fund’s NAV.

The last reported sale price, NAV per share and percentage discount to NAV per share of the Common Shares as of February 19, 2016 were $14.00, $15.55 and 9.97%, respectively. As of February 19, 2016, the Fund had 8,718,425 Common Shares outstanding and net assets of the Fund were $135,552,751.

The Fund

The Fund is a diversified, closed-end management investment company registered under the 1940 Act. The Fund was organized on October 26, 1970 as a Delaware corporation and was reorganized on October 5, 1984 as a Massachusetts business trust pursuant to an Agreement and Declaration of Trust, which was amended and restated on August 26, 2003, as amended (the “Declaration of Trust”). The Fund commenced operations following an initial public offering on January 29, 1971, pursuant to which the Fund issued an aggregate of 5,500,000 Common Shares of beneficial interest, $1.00 par value. The Fund’s principal office is located at 601 Congress Street, Boston, Massachusetts 02210 and its phone number is 800-225-6020.

The following provides information about the Fund’s outstanding securities as of October 31, 2015.

Use of Proceeds

Subject to the remainder of this section, and unless otherwise specified in a Prospectus Supplement, the Fund currently intends to invest substantially all of the net proceeds of any sales of Common Shares pursuant to this Prospectus in accordance with its investment objectives and policies as described under “Investment Objectives” and “Investment Strategies” within three months of receipt of such proceeds. Such investments may be delayed up to three months if suitable investments are unavailable at the time or for other reasons, such as market volatility or lack of liquidity in the markets of suitable investments. Pending such investment, the Fund anticipates that it will invest the proceeds in short-term money market instruments, securities with remaining maturities of less than one year, cash or cash equivalents. A delay in the anticipated use of proceeds could lower returns and reduce the Fund’s distribution to Common Shareholders or result in a distribution consisting in part of principally of a return of capital.

Investment Objectives

The Fund’s primary investment objective is to generate income for distribution to its shareholders, with capital appreciation as a secondary objective. There can be no assurance that the Fund will achieve its investment objectives. The Fund’s investment objectives are not fundamental policies and may be changed without the approval of a majority of the outstanding voting securities (as defined in the 1940 Act) of the Fund.

Investment Strategies

The preponderance of the Fund’s assets are invested in a diversified portfolio of debt securities issued by U.S. and non-U.S. corporations and governments, some of which may carry equity features. The Fund emphasizes corporate debt securities which pay interest on a fixed or contingent basis and which may possess certain equity features, such as conversion or exchange rights, warrants for the acquisition of the stock of the same or different issuers, or participations based on revenues, sales or profits. The Fund also may purchase preferred securities and may acquire common stock through the exercise of conversion or exchange rights acquired in connection with other securities owned by the Fund. The Fund will not acquire any additional preferred securities or common stock if as a result of that acquisition the value of all preferred securities and common stocks in the Fund’s portfolio would exceed 20% of its total assets. Up to 50% of the value of the Fund’s assets may be invested in restricted securities acquired through private placements. The Fund may purchase mortgage-backed securities. The Fund also may purchase and sell derivative instruments. In addition, the Fund may invest in repurchase agreements.

At least 30% of Fund’s net assets (plus borrowings for investment purposes) will be represented by (a) debt securities which are rated, at the time of acquisition, investment grade ( i.e. , at least “Baa” by Moody’s Investors Service, Inc. (“Moody’s”) or “BBB” by Standard & Poor’s Ratings Services (“S&P”)) or in unrated securities determined by the Subadvisor to be of comparable credit quality, (b) securities issued or guaranteed by the U.S. government or its agencies and instrumentalities, and (c) cash or cash equivalents. The remaining 70% of the Fund’s net assets (plus borrowings for investment purposes) may be invested in debt securities of any credit quality, including securities rated below investment grade ( i.e. , rated “Ba” or lower by Moody’s or “BB” or lower by S&P). Debt securities of below investment grade quality are regarded as having predominantly speculative characteristics with respect to the issuer’s ability to pay interest and repay principal and are commonly referred to as “junk bonds” or “high yield securities.” While the Fund focuses on intermediate- and longer-term debt securities, the Fund may acquire securities of any maturity and is not subject to any limits as to the average maturity of its overall portfolio.

Securities rated “BBB” by S&P are regarded by S&P as having an adequate capacity to pay interest or dividends and repay capital or principal, as the case may be; whereas such securities normally exhibit adequate protection parameters, adverse economic conditions or changing circumstances are more likely, in the opinion of S&P, to lead to a weakened capacity to pay interest or dividends and repay capital or principal for securities in this category than in higher rating categories. Securities rated “Baa” by Moody’s are considered by Moody’s as medium to lower medium grade securities; they are neither highly protected nor poorly secured; interest or dividend payments and capital or principal security, as the case may be, appear to Moody’s to be adequate for the present but certain protective elements may be lacking or may be characteristically unreliable over time; and, in the opinion of Moody’s, securities in this rating category lack outstanding investment characteristics and in fact have speculative characteristics as well. Below investment grade securities and comparable unrated securities involve substantial risk

of loss, are considered highly speculative with respect to the issuer’s ability to pay interest and any required redemption or principal payments and are susceptible to default or decline in market value due to adverse economic and business developments. Securities rated Ba or BB may face significant ongoing uncertainties or exposure to adverse business, financial or economic conditions that could lead to the issuer being unable to meet its financial commitments. The protection of interest and principal may be moderate and not well safeguarded during both good and bad times. Securities rated B generally lack the characteristics of a desirable investment. Assurance of interest and principal payments over the long term may be low, and such securities are more vulnerable to nonpayment than obligations rated BB or Ba. Adverse business, financial or economic conditions will likely impair the issuer’s capacity or willingness to meet its financial commitments. The descriptions of the investment grade rating categories by Moody’s and S&P, including a description of their speculative characteristics, are set forth in the SAI. All references to securities ratings by Moody’s and S&P in this Prospectus shall, unless otherwise indicated, include all securities within each such rating category ( e.g. , “Baa1”, “Baa2” and “Baa3” in the case of Moody’s and “BBB+”, “BBB” and “BBB-” in the case of S&P). All percentage and ratings limitations on securities in which the Fund may invest apply at the time of making an investment and shall not be considered violated if an investment rating is subsequently downgraded to a rating that would have precluded the Fund’s initial investment in such security. In the event of such security downgrade, the Fund will sell the portfolio security as soon as the Subadvisor believes it to be prudent to do so in order to again cause the Fund to be within the percentage and ratings limitations set forth in this Prospectus. In the event that the Fund disposes of a portfolio security subsequent to its being downgraded, the Fund may experience a greater risk of loss than if such security had been sold prior to such downgrade.

In managing the Fund’s portfolio, the Subadvisor concentrates first on sector selection by deciding which types of bonds and industries to emphasize at a given time, and then which individual bonds to buy. When making sector and industry allocations, the Subadvisor tries to anticipate shifts in the business cycle, using top-down analysis to determine which sectors and industries may benefit over the next 12 months. In choosing individual securities, the Subadvisor uses bottom-up research to find securities that appear comparatively undervalued. The Subadvisor looks at bonds of all quality levels and maturities from many different issuers, potentially including U.S. dollar-denominated securities of foreign corporations and governments. There can be no assurance that the Fund will achieve its investment objectives.

PORTFOLIO INVESTMENTS

Corporate debt securities

The Fund invests in corporate debt obligations. Corporate debt obligations are subject to the risk of an issuer’s inability to meet principal and interest payments on the obligations and also may be subject to price volatility due to such factors as market interest rates, market perception of the creditworthiness of the issuer and general market liquidity.

U.S. government and foreign government securities

U.S. government securities in which the Fund invests include debt obligations of varying maturities issued by the U.S. Treasury or issued or guaranteed by an agency or instrumentality of the U.S. government. U.S. government securities include securities issued or guaranteed by the U.S. government or its authorities, agencies, or instrumentalities. Foreign government securities include securities issued or guaranteed by foreign governments (including political subdivisions) or their authorities, agencies, or instrumentalities or by supra-national agencies. Different kinds of U.S. government securities and foreign government securities have different kinds of government support. For example, some U.S. government securities ( e.g. , U.S. Treasury bills, Treasury notes and Treasury bonds, which differ only in their interest rates, maturities and times of issuance) are supported by the full faith and credit of the U.S. Other U.S. government securities are issued or guaranteed by federal agencies or government-chartered or -sponsored enterprises, but are neither guaranteed nor insured by the U.S. government ( e.g. , debt securities issued by the Federal Home Loan Mortgage Corporation (“Freddie Mac”), Federal National Mortgage Association (“Fannie Mae”), and Federal Home Loan Banks (“FHLBs”)). Others may be supported by: (i) the right of the issuer to borrow from the U.S. Treasury; (ii) the discretionary authority of the U.S. government to purchase the agency’s obligations; or (iii) only the credit of the issuer. Similarly, some foreign government securities are supported by the full faith and credit of a foreign national government or political subdivision and some are not. Foreign government securities of some countries may involve varying degrees of credit risk as a result of financial or political instability in those countries and the possible inability of the Fund to enforce its rights against the foreign

government issuer. As with other fixed-income securities, sovereign issuers may be unable or unwilling to make timely principal or interest payments.

Supra-national agencies are agencies whose member nations make capital contributions to support the agencies’ activities, and include the International Bank for Reconstruction and Development (the “World Bank”), the Asian Development Bank, the European Coal and Steel Community, and the Inter-American Development Bank.

Like other fixed-income securities, U.S. government securities are subject to market risk and their market values typically will change as interest rates fluctuate. For example, the value of the Fund’s investment in U.S. government securities may fall during times of rising interest rates. Yields on U.S. government securities tend to be lower than those of corporate securities of comparable maturities.

In addition to investing directly in U.S. government securities and foreign government securities, the Fund may purchase certificates of accrual or similar instruments evidencing undivided ownership interests in interest payments and/or principal payments of U.S. government securities and foreign government securities. Certificates of accrual and similar instruments may be more volatile than other government securities.

Mortgage-backed securities

The Fund may invest in mortgage-backed securities which represent participation interests in pools of adjustable and fixed rate mortgage loans which are guaranteed by agencies or instrumentalities of the U.S. government. Unlike conventional debt obligations, mortgage-backed securities provide monthly payments derived from the monthly interest and principal payments (including any prepayments) made by the individual borrowers on the pooled mortgage loans. The mortgage loans underlying mortgage-backed securities are generally subject to a greater rate of principal prepayments in a declining interest rate environment and to a lesser rate of principal prepayments in an increasing interest rate environment. Under certain interest and prepayment scenarios, the Fund may fail to recover the full amount of its investment in mortgage-backed securities notwithstanding any direct or indirect governmental or agency guarantee. Since faster than expected prepayments must usually be invested in lower yielding securities, mortgage-backed securities are less effective than conventional bonds in “locking in” a specified interest rate. In a rising interest rate environment, a declining prepayment rate may extend the average life of many mortgage-backed securities. Extending the average life of a mortgage-backed security increases the risk of depreciation due to future increases in market interest rates. Government-sponsored entities such as the FHLMC, FNMA and FHLB, although chartered or sponsored by Congress, are not funded by congressional appropriations and the debt and mortgage-backed securities issued by them are neither guaranteed nor issued by the U.S. government.

The Fund’s investments in mortgage-backed securities may include conventional mortgage pass through securities and certain classes of multiple class collateralized mortgage obligations (“CMOs”). In order to reduce the risk of prepayment for investors, CMOs are issued in multiple classes, each having different maturities, interest rates, payment schedules and allocations of principal and interest on the underlying mortgages. Senior CMO classes will typically have priority over residual CMO classes as to the receipt of principal and/or interest payments on the underlying mortgages. The CMO classes in which the Fund may invest include but are not limited to sequential and parallel pay CMOs, including planned amortization class (“PAC”) and target amortization class (“TAC”) securities.

Different types of mortgage-backed securities are subject to different combinations of prepayment, extension, interest rate and/or other market risks. Conventional mortgage pass through securities and sequential pay CMOs are subject to all of these risks, but are typically not leveraged. PACs, TACs and other senior classes of sequential and parallel pay CMOs involve less exposure to prepayment, extension and interest rate risk than other mortgage-backed securities, provided that prepayment rates remain within expected prepayment ranges or “collars.”

Illiquid securities

The Fund may invest up to 20% of its total assets in illiquid securities ( i.e. , securities that are not readily marketable). For this purpose, “illiquid securities” may include certain securities that are not registered (“restricted securities”) under the Securities Act of 1933, as amended (the “1933 Act”), including commercial paper issued in reliance on Section 4(a)(2) of the 1933 Act and securities offered and sold to “qualified institutional buyers” under Rule 144A under the 1933 Act. If the Board of Trustees (the “Board”) determines, based upon a continuing review of the trading markets for specific Section 4(a)(2) commercial paper or Rule 144A securities, that these instruments are liquid, they will not be subject to the 20% limit on illiquid investments. The Board has adopted guidelines and

delegated to the Advisor the daily function of determining the monitoring and liquidity of restricted securities. The Board will, however, retain sufficient oversight and be ultimately responsible for these determinations. The Board will carefully monitor the Fund’s investments in these securities, focusing on such important factors, among others, as valuation, liquidity and availability of information. This investment practice could have the effect of increasing the level of illiquidity in the Fund if qualified institutional buyers become for a time uninterested in purchasing these restricted securities.

Repurchase agreements maturing in more than seven days are considered illiquid, unless an agreement can be terminated after a notice period of seven days or less.

As long as the SEC maintains the position that most swap contracts, caps, floors, and collars are illiquid, the Fund will continue to designate these instruments as illiquid for purposes of its 20% illiquid limitation unless the instrument includes a termination clause or has been determined to be liquid based on a case-by-case analysis pursuant to procedures approved by the Board.

Equity securities

The Fund may invest up to 20% of its assets in preferred securities and common stocks. The Fund may purchase preferred securities and may acquire common stock through the exercise of conversion or exchange rights acquired in connection with other securities owned by the Fund. The Fund normally will invest in such securities when the Subadvisor believes that they will provide a sufficiently high yield to attain the Fund’s investment objectives. The Fund also may purchase income producing securities which are convertible into or come with rights to purchase preferred securities and common stocks.

Fixed rate preferred securities have fixed dividend rates. They can be perpetual, with no mandatory redemption date, or issued with a fixed mandatory redemption date. Certain issues of preferred securities are convertible into other equity securities. Perpetual preferred securities provide a fixed dividend throughout the life of the issue, with no mandatory retirement provisions, but may be callable. Sinking fund preferred securities provide for the redemption of a portion of the issue on a regularly scheduled basis with, in most cases, the entire issue being retired as of a future date. The value of fixed rate preferred securities can be expected to vary inversely with interest rates.

Adjustable rate preferred securities have a variable dividend rate which is determined periodically, typically quarterly, according to a formula based on a specified premium or discount to the yield on particular U.S. Treasury securities, typically the highest base-rate yield of one of three U.S. Treasury securities: the 90-day Treasury bill; the 10-year Treasury note; and either the 20-year or 30-year Treasury bond or other index. The premium or discount to be added to or subtracted from this base-rate yield is fixed at the time of issuance and cannot be changed without the approval of the holders of the adjustable rate preferred securities. Some adjustable rate preferred securities have a maximum and a minimum rate and in some cases are convertible into common stock.

Auction rate preferred securities pay dividends that adjust based upon periodic auctions. Such preferred securities are similar to short-term corporate money market instruments in that an auction rate preferred stockholder has the opportunity to sell the preferred securities at its liquidation value in an auction, normally conducted at least every 49 days, through which buyers set the dividend rate in a bidding process for the next period. The dividend rate set in the auction depends upon market conditions and the credit quality of the particular issuer. Typically, the auction rate preferred securities’ dividend rate is limited to a specified maximum percentage of an external commercial paper index as of the auction date. Further, the terms of auction rate preferred securities generally provide that they are redeemable by the issuer at certain times or under certain conditions.

Common stocks are shares of a corporation or other entity that entitle the holder to a pro rata share of the profits, if any, of the corporation without preference over any other shareholder or class of shareholders, including holders of such entity’s preferred securities and other senior equity securities. Common stock usually carries with it the right to vote and frequently an exclusive right to do so. In selecting common stocks for investment, the Fund expects generally to focus more on the security’s dividend paying capacity than on its potential for capital appreciation.

Non-U.S. securities

While the Fund primarily invests in the securities of U.S. issuers, the Fund may invest in securities of corporate and governmental issuers located outside the U.S., including emerging market issuers. The Fund may invest up to 30% of its total assets in securities that are denominated in foreign currencies.

Sovereign debt obligations

The Fund may invest in sovereign debt obligations, which involve special risks that are not present in corporate debt obligations. The foreign issuer of the sovereign debt or the foreign governmental authorities that control the repayment of the debt may be unable or unwilling to repay principal or interest when due, and the Fund may have limited recourse in the event of a default. During periods of economic uncertainty, the market prices of sovereign debt, and the Fund’s NAV, to the extent it invests in such securities, may be more volatile than prices of debt obligations of U.S. issuers. In the past, certain foreign countries have encountered difficulties in servicing their debt obligations, withheld payments of principal and interest and declared moratoria on the payment of principal and interest on their sovereign debt.

Money market instruments

Money market instruments include short-term U.S. government securities, U.S. dollar-denominated, high quality commercial paper (unsecured promissory notes issued by corporations to finance their short-term credit needs), certificates of deposit, bankers’ acceptances and repurchase agreements relating to any of the foregoing. U.S. government securities include Treasury notes, bonds and bills, which are direct obligations of the U.S. government backed by the full faith and credit of the U.S., and securities issued by agencies and instrumentalities of the U.S. government, which may be guaranteed by the U.S. Treasury, may be supported by the issuer’s right to borrow from the U.S. Treasury or may be backed only by the credit of the U.S. federal agency or instrumentality itself.

Hedging and interest rate transactions

The Fund may, but is not required to, use various hedging and interest rate transactions described below to mitigate risks or facilitate portfolio management. Such transactions are regularly used by many mutual funds and other institutional investors. Although the Subadvisor seeks to use these practices to further the Fund’s investment objectives, no assurance can be given that these practices will achieve this result.

The Fund may purchase and sell derivative instruments such as exchange-listed and over-the-counter put and call options on securities, financial futures, fixed-income, interest rate and equity indices, and other financial instruments, purchase and sell financial futures contracts and options thereon, and enter into various interest rate transactions such as swaps, caps, floors or collars or credit transactions and credit default swaps. The Fund also may purchase derivative instruments that combine features of these instruments. Collectively, all of the above are referred to as “Strategic Transactions.” The Fund generally seeks to use Strategic Transactions as a portfolio management or hedging technique to seek to protect against possible adverse changes in the market value of securities held in or to be purchased for the Fund’s portfolio, protect the value of the Fund’s portfolio, facilitate the sale of certain securities for investment purposes, manage the effective interest rate exposure of the Fund, including the effective yield paid on any preferred shares issued by the Fund, manage the effective maturity or duration of the Fund’s portfolio or establish positions in the derivatives markets as a temporary substitute for purchasing or selling particular securities. The Fund does not engage in these transactions for speculative purposes.

Strategic Transactions have risks, including the imperfect correlation between the value of such instruments and the underlying assets, the possible default of the other party to the transaction or illiquidity of the derivative instruments. Furthermore, the ability to use Strategic Transactions to the benefit of the Fund depends on the Subadvisor’s ability to predict pertinent market movements, which cannot be assured. Thus, the use Strategic Transactions may result in a loss greater than if they had not been used, may require the Fund to sell or purchase 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 that it might otherwise sell. Additionally, amounts paid by the Fund as premiums and cash or other assets held in margin accounts with respect to Strategic Transactions are not otherwise available to the Fund for investment purposes.

A more complete discussion of Strategic Transactions and their risks is contained in the SAI.

TEMPORARY DEFENSIVE STRATEGIES

There may be times when, in the Subadvisor’s judgment, conditions in the securities markets would make pursuit of the Fund’s investment strategy inconsistent with achievement of the Fund’s investment objectives. At such times, the Subadvisor may employ alternative strategies primarily to seek to reduce fluctuations in the value of the Fund’s assets. In implementing these temporary defensive strategies, depending on the circumstances, the Fund may invest

an unlimited portion of its portfolio in short-term money market instruments, securities with remaining maturities of less than one year, cash or cash equivalents. It is impossible to predict when, or for how long, the Fund may use these alternative strategies.

ADDITIONAL PORTFOLIO INVESTMENTS

Structured securities

The Fund may invest in structured securities including notes, bonds or debentures, the value of the principal of and/or interest on which is to be determined by reference to changes in the value of specific currencies, interest rates, commodities, indices or other financial indicators (the “Reference”) or the relative change in two or more References. The interest rate or the principal amount payable upon maturity or redemption may be increased or decreased depending upon changes in the applicable Reference. The terms of the structured securities may provide that in certain circumstances no principal is due at maturity and, therefore, may result in the loss of the Fund’s investment. Structured securities may be positively or negatively indexed, so that appreciation of the Reference may produce an increase or decrease in the interest rate or value of the security at maturity. In addition, the change in interest rate or the value of the security at maturity may be a multiple of the change in the value of the Reference. Consequently, structured securities entail a greater degree of market risk than other types of debt obligations. Structured securities also may be more volatile, less liquid and more difficult to price accurately than less complex fixed-income investments.

When-Issued and Forward Commitment Securities

The Fund may purchase securities on a when-issued or forward commitment basis. “When-issued” refers to securities whose terms are available and for which a market exists, but which have not been issued. The Fund will engage in when-issued transactions with respect to securities purchased for its portfolio in order to obtain what is considered to be an advantageous price and yield at the time of the transaction. For when-issued transactions, no payment is made until delivery is due, often a month or more after the purchase. In a forward commitment transaction, the Fund contracts to purchase securities for a fixed price at a future date beyond customary settlement time.

When the Fund engages in a forward commitment or when-issued transaction, the Fund relies on the issuer or seller to consummate the transaction. The failure of the issuer or seller to consummate the transaction may result in the Fund losing the opportunity to obtain a price and yield considered to be advantageous. The purchase of securities on a when-issued or forward commitment basis also involves a risk of loss if the value of the security to be purchased declines prior to the settlement date.

On the date that the Fund enters into an agreement to purchase securities on a when-issued or forward commitment basis, the Fund will segregate in a separate account cash or liquid securities, of any type or maturity, equal in value to the Fund’s commitment. These assets will be valued daily at market, and additional cash or securities will be segregated in a separate account to the extent that the total value of the assets in the account declines below the amount of the when-issued commitments. Alternatively, the Fund may enter into offsetting contracts for the forward sale of other securities that it owns.

Repurchase agreements

The Fund may enter into repurchase agreements. In a repurchase agreement the Fund would buy a security for a relatively short period (usually not more than 7 days) subject to the obligation to sell it back to the seller at a fixed time and price plus accrued interest. The Fund will enter into repurchase agreements only with member banks of the Federal Reserve System and with “primary dealers” in U.S. government securities. When the Fund enters into a repurchase agreement, it receives collateral which is held in a segregated account by the Fund’s custodian. The collateral amount is marked-to-market and monitored on a daily basis to ensure that the collateral held is in an amount not less than the principal amount of the repurchase agreement plus any accrued interest. In the event of a default by the counterparty, realization of the collateral proceeds could be delayed, during which time the collateral value may decline.

Reverse repurchase agreements

The Fund may enter into “reverse” repurchase agreements. To the extent permitted under the 1940 Act, and related guidance of the SEC and its staff, under a reverse repurchase agreement, a fund may sell a debt security and agree to repurchase it at an agreed upon time and at an agreed upon price. The Fund maintains liquid assets such as cash, Treasury bills or other U.S. government securities having an aggregate value equal to the amount of such commitment to repurchase including accrued interest, until payment is made. A reverse repurchase agreement may be considered a form of leveraging and may increase fluctuations in a fund’s NAV per share.

The Fund intends to use reverse repurchase agreements to obtain investment leverage either alone and/or pursuant to the LA. To the extent permitted under the LA, in a reverse repurchase transaction, the Fund temporarily transfers possession of a portfolio instrument to another party in return for cash. At the same time, the Fund agrees to repurchase the instrument at an agreed upon time and price, which reflects an interest payment. The value of the portfolio securities transferred may substantially exceed the purchase price received by the Fund under the reverse repurchase agreement transaction and, during the life of the reverse repurchase agreement transaction, the Fund may be required to transfer additional securities if the market value of those securities initially transferred declines. In engaging in a reverse repurchase transaction, the Fund may transfer (“sell”) any of its portfolio securities to a broker-dealer, bank or another financial institution counterparty. Each such counterparty must be approved by the Fund. In accordance with guidance from the SEC and its staff from time to time in effect, the Fund will pledge, earmark or segregate liquid assets equal to repayment obligations under the reverse repurchase agreements.

Reverse repurchase agreements involve the risk that the market value of securities purchased by the Fund with proceeds of the transaction may decline below the repurchase price of the securities sold by the Fund which it is obligated to repurchase. The Fund also will continue to be subject to the risk of a decline in the market value of the securities sold under the agreements because it will reacquire those securities upon effecting their repurchase. The Fund may designate any or all securities as ineligible for reverse repurchase transactions with any counterparty, whether or not such securities are currently the subject of any such transaction, for any reason. Under the procedures established by the Trustees, the Advisor will monitor the creditworthiness of the Fund’s reverse repurchase agreement counterparties.

Asset-backed securities

The Fund may invest in asset-backed securities. Asset-backed securities are often subject to more rapid repayment than their stated maturity date would indicate as a result of the pass-through of prepayments of principal on the underlying loans. During periods of declining interest rates, prepayment of loans underlying asset-backed securities can be expected to accelerate. Accordingly, the Fund’s ability to maintain positions in these securities will be affected by reductions in the principal amount of such securities resulting from prepayments, and its ability to reinvest the returns of principal at comparable yields is subject to generally prevailing interest rates at that time.

Brady bonds

The Fund may invest in Brady Bonds and other sovereign debt securities of countries that have restructured or are in the process of restructuring sovereign debt pursuant to the Brady Plan. Brady Bonds are debt securities described as part of a restructuring plan created by U.S. Treasury Secretary Nicholas F. Brady in 1989 as a mechanism for debtor nations to restructure their outstanding external indebtedness (generally, commercial bank debt). In restructuring its external debt under the Brady Plan framework, a debtor nation negotiates with its existing bank lenders as well as multilateral institutions such as the World Bank and the International Monetary Fund (the “IMF”). The Brady Plan facilitates the exchange of commercial bank debt for newly issued bonds (known as Brady Bonds). The World Bank and the IMF provide funds pursuant to loan agreements or other arrangements which enable the debtor nation to collateralize the new Brady Bonds or to repurchase outstanding bank debt at a discount. Under these arrangements the IMF debtor nations are required to implement domestic monetary and fiscal reforms. These reforms have included the liberalization of trade and foreign investment, the privatization of state-owned enterprises and the setting of targets for public spending and borrowing. These policies and programs seek to promote the debtor country’s ability to service its external obligations and promote its economic growth and development. The Brady Plan only sets forth general guiding principles for economic reform and debt reduction, emphasizing that solutions must be negotiated on a case-by-case basis between debtor nations and their creditors.

REITs

The Fund may invest in common and preferred interests in real estate investment trusts (“REITs”). REITs primarily invest in income producing real estate or real estate related loans or interests. REITs are generally classified as equity REITs, mortgage REITs or a combination of equity and mortgage REITs. Equity REITs invest the majority of their assets directly in real property and derive income primarily from the collection of rents. Equity REITs also can realize capital gain by selling properties that have appreciated in value. Mortgage REITs invest the majority of their assets in real estate mortgages and derive income from the collection of interest payments. REITs are not taxed on income distributed to shareholders provided they comply with the applicable requirements of the Code. The Fund will in some cases indirectly bear its proportionate share of any management and other expenses paid by REITs in which it invests in addition to the expenses paid by the Fund. Debt securities issued by REITs are, for the most part, general and unsecured obligations and are subject to risks associated with REITs.

Other investment companies

The Fund may invest in the securities of other investment companies to the extent that such investments are consistent with the Fund’s investment objectives and policies and permissible under the 1940 Act. As a stockholder in an investment company, the Fund will bear its ratable share of that investment company’s expenses, and would remain subject to payment of the Fund’s investment management fees and other expenses with respect to the assets so invested. Common Shareholders would therefore be subject to duplicative expenses to the extent the Fund invests in other investment companies. In addition, these other investment companies may utilize leverage, in which case an investment would subject the Fund to additional risks associated with leverage. See “Risk Factors—Leverage Risk.” The Fund, as a holder of the securities of other investment companies, will bear its pro rata portion of the other investment companies’ expenses, including advisory fees. These expenses are in addition to the direct expenses of the Fund’s own operations.

OTHER INVESTMENT POLICIES

Borrowing

The Fund may use leverage to the extent permitted by the 1940 Act, this Prospectus, and the LA. The Fund is authorized to utilize leverage through borrowings, reinvestment of securities lending collateral or repurchase agreement proceeds, and/or the issuance of preferred shares, including the issuance of debt securities. The Fund is party to the LA as described in “—Description of Capital Structure—Liquidity Facility.” Borrowings, together with the issuance of preferred shares, or other “senior securities” as that term is defined in the 1940 Act, may not be in an aggregate amount that would, immediately after giving effect to the drawdown, exceed 33 ^1/3 % of the Fund’s total assets (including any assets attributable to financial leverage from senior securities) minus the sum of accrued liabilities (other than liabilities from senior securities).

Portfolio turnover

The Fund may engage in short-term trading strategies, and securities may be sold without regard to the length of time held when, in the opinion of the Subadvisor, investment considerations warrant such action. Short term trading may have the effect of increasing portfolio turnover rate. A high turnover rate (100% or more) necessarily involves greater trading costs to the Fund and may result in the realization of net short term capital gain. The portfolio turnover rate for the Fund for the fiscal years ended October 31, 2015 and October 31, 2014 was 74% and 71%, respectively. The success of short-term trading will depend upon the ability of the Subadvisor to evaluate particular securities, to anticipate relevant market factors, including trends of interest rates and earnings and variations from such trends, to obtain relevant information, to evaluate it promptly, and to take advantage of its evaluations by completing transactions on a favorable basis. There can be no assurance that the Subadvisor will be successful in that evaluation. If securities are not held for the applicable holding periods, dividends paid on them will not qualify for the advantageous U.S. federal tax rates. See “Investment Strategies” and “U.S. Federal Income Tax Matters.”

Securities loans

The Fund is party to the LA as described in “—Description of Capital Structure—Liquidity Facility.” The Fund may seek to obtain additional income or portfolio leverage by making secured loans of its portfolio securities with a value of up to 33 ^1/3 % of total assets. In such transactions, the borrower pays to the Fund an amount equal to any

dividends or interest received on loaned securities. The Fund retains all or a portion of the dividends, interest, capital gains, and/or other distributions received on investment of cash collateral in short-term obligations of the U.S. government, cash equivalents (including shares of a fund managed by the Fund’s investment adviser or an affiliate thereof), or other investments consistent with the Fund’s investment objective, policies, and restrictions, or receives a fee from the borrower. As a result of investing such cash collateral in such investments, the Fund will receive the benefit of any gains and bear any losses generated by such investments. All securities loans will be made pursuant to agreements requiring that the loans be continuously secured by collateral in cash or short-term debt obligations at least equal at all times to the market value of the loaned securities. The Fund may pay reasonable finders’, administrative and custodial fees in connection with loans of its portfolio securities. Although voting rights or rights to consent accompanying loaned securities pass to the borrower, the Fund retains the right to call the loans at any time on reasonable notice, and it will do so in order that the securities may be voted by the Fund with respect to matters materially affecting the Fund’s investment. The Fund may also call a loan in order to sell the securities involved. Lending portfolio securities involves risks of delay in recovery of the loaned securities or, in some cases, loss of rights in the collateral should the borrower commence an action relating to bankruptcy, insolvency or reorganization. The use of securities lending collateral to obtain leverage in the Fund’s investment portfolio may subject the Fund to greater risk of loss than the use of traditional securities lending to earn incremental income via investing collateral solely in short-term U.S. government securities or cash equivalents.

Foreign currency transactions

The value of non-U.S. assets as measured in U.S. dollars may be affected favorably or unfavorably by changes in foreign currency rates and exchange control regulations. Currency exchange rates also can be affected unpredictably by intervention by U.S. or foreign governments or central banks, or the failure to intervene, or by currency controls or political developments in the U.S. or abroad. The Fund may (but is not required to) engage in transactions to hedge against changes in foreign currencies, and will use such hedging techniques when the Advisor or the Subadvisor deems appropriate. Foreign currency exchange transactions may be conducted on a spot ( i.e. , cash) basis at the spot rate prevailing in the foreign currency exchange market or through entering into derivative currency transactions. Currency futures contracts are exchange-traded and change in value to reflect movements of a currency or a basket of currencies. Settlement must be made in a designated currency.

Forward foreign currency exchange contracts are individually negotiated and privately traded so they are dependent upon the creditworthiness of the counterparty. Such contracts may be used when a security denominated in a foreign currency is purchased or sold, or when the receipt in a foreign currency of dividend or interest payments on such a security is anticipated. A forward contract can then “lock in” the U.S. dollar price of the security or the U.S. dollar equivalent of such dividend or interest payment, as the case may be.

Additionally, when the Advisor or the Subadvisor believes that the currency of a particular foreign country may suffer a substantial decline against the U.S. dollar, it may enter into a forward contract to sell, for a fixed amount of dollars, the amount of foreign currency approximating the value of some or all of the securities held that are denominated in such foreign currency. The precise matching of the forward contract amounts and the value of the securities involved generally will not be possible. In addition, it may not be possible to hedge against long-term currency changes. Cross-hedging may be performed by using forward contracts in one currency (or basket of currencies) to hedge against fluctuations in the value of securities denominated in a different currency if the Advisor or the Subadvisor determines that there is an established historical pattern of correlation between the two currencies (or the basket of currencies and the underlying currency). Use of a different foreign currency magnifies exposure to foreign currency exchange rate fluctuations. Forward contracts also may be used to shift exposure to foreign currency exchange rate changes from one currency to another. Short-term hedging provides a means of fixing the dollar value of only a portion of portfolio assets. Income or gain earned on any of the Fund’s foreign currency transactions generally will be treated as fully taxable income ( i.e. , income other than tax-advantaged dividends).

Currency transactions are subject to the risk of a number of complex political and economic factors applicable to the countries issuing the underlying currencies. Furthermore, unlike trading in most other types of instruments, there is no systematic reporting of last sale information with respect to the foreign currencies underlying the derivative currency transactions. As a result, available information may not be complete. In an over-the-counter trading environment, there are no daily price fluctuation limits. There may be no liquid secondary market to close out options purchased or written, or forward contracts entered into, until their exercise, expiration or maturity. There also is the risk of default by, or the bankruptcy of, the financial institution serving as counterparty.

USE OF LEVERAGE BY THE FUND

The Fund may use leverage to the extent permitted by the 1940 Act, this Prospectus, and the LA. The Fund is authorized to utilize leverage through borrowings, reinvestment of securities lending collateral or repurchase agreement proceeds, and/or the issuance of preferred shares, including the issuance of debt securities. See “—Other Investment Policies—Borrowing.” The Fund is party to the LA as described in “—Description of Capital Structure—Liquidity Facility.”

The Fund’s leverage strategy may not be successful. By leveraging its investment portfolio, the Fund creates an opportunity for increased net income or capital appreciation. However, the use of leverage also involves risks, which can be significant. These risks include the possibility that the value of the assets acquired with such borrowing decreases although the Fund’s liability is fixed, greater volatility in the Fund’s NAV and the market price of the Fund’s Common Shares and higher expenses. Because the Advisor’s fee is based upon a percentage of the Fund’s managed assets, the Advisor’s fee will be higher if the Fund is leveraged and the Advisor will have an incentive to leverage the Fund. The Advisor intends only to leverage the Fund when it believes that the potential return on the additional investments acquired through the use of leverage is likely to exceed the costs incurred in connection with the offering.

At October 31, 2015, the Fund had borrowings under its prior credit facility of $86,900,000. The average daily loan balance, weighted average interest rate and maximum daily loan outstanding for the year ended October 31, 2015 were as follows:

The Fund’s borrowings under its credit facility at October 31, 2015 equaled approximately 35.60% of the Fund’s total assets (including the proceeds of such leverage). The Fund’s asset coverage ratio as of October 31, 2015 was 281%. See “—Other Investment Policies—Borrowing” for a brief description of the Fund’s liquid facility agreement.

Assuming the utilization of leverage in the amount of 35.60% of the Fund’s total assets and an annual interest rate of 0.89% payable on such leverage based on market rates as of October 31, 2015, the additional income that the Fund must earn (net of expenses) in order to cover such leverage is approximately $773,410. Actual costs of leverage may be higher or lower than that assumed in the previous example. Under normal market conditions, interest charged under the LA is at the rate of one-month LIBOR plus 0.60% effective December 2, 2015 and at a rate of one-month LIBOR plus 0.70% prior to December 2, 2015. The current interest rate reflects a decrease from the prior rate.

Following an offering of additional Common Shares from time to time, the Fund may increase the amount of leverage outstanding. The Fund may engage in additional borrowings, securities lending, and reverse repurchase agreements in order to maintain the Fund’s desired leverage ratio. Leverage creates a greater risk of loss, as well as a potential for more gain, for the Common Shares than if leverage was not used. Interest on borrowings may be at a fixed or floating rate and generally will be based on short-term rates. The costs associated with the Fund’s use of leverage, including the issuance of such leverage and the payment of dividends or interest on such leverage, will be borne entirely by the Common Shareholders. As long as the rate of return, net of applicable Fund expenses, on the Fund’s investment portfolio investments purchased with leverage exceeds the costs associated with such leverage, the Fund will generate more return or income than will be needed to pay such costs. In this event, the excess will be available to pay higher dividends to Common Shareholders. Conversely, if the Fund’s return on such assets is less than the cost of leverage and other Fund expenses, the return to the Common Shareholders will diminish. To the extent that the Fund uses leverage, the NAV and market price of the Common Shares and the yield to Common Shareholders will be more volatile. The Fund’s leveraging strategy may not be successful. See “Risk Factors—Leverage Risk.”

The following table is designed to illustrate the effect on the return to a holder of the Fund’s Common Shares of leverage in the amount of approximately 35.60% of the Fund’s total assets, assuming hypothetical annual returns of the Fund’s investment portfolio of minus 10% to plus 10%. As the table shows, leverage generally increases the return to Common Shareholders when portfolio return is positive and greater than the cost of leverage and decreases the return when the portfolio return is negative or less than the cost of leverage. The figures appearing in the table are hypothetical. Actual returns may be greater or less than those appearing in the table.

Risk Factors

Below are descriptions of the main factors that may play a role in shaping the Fund’s overall risk profile. The descriptions are grouped by general risks and strategy risks. For further details about Fund risks, including additional risk factors that are not discussed in this Prospectus because they are not considered primary factors, see the Fund’s SAI.

The principal risks of investing in the Fund are summarized in the Prospectus Summary above. Below are descriptions of the main factors that may play a role in shaping the Fund’s overall risk profile. The descriptions appear in alphabetical order, not in order of importance.

General Risks

Cybersecurity risk

Intentional cybersecurity breaches include unauthorized access to systems, networks, or devices (such as through “hacking” activity); infection from computer viruses or other malicious software code; and attacks that shut down, disable, slow, or otherwise disrupt operations, business processes, or website access or functionality. In addition, unintentional incidents can occur, such as the inadvertent release of confidential information (possibly resulting in the violation of applicable privacy laws).

A cybersecurity breach could result in the loss or theft of customer data or funds, the inability to access electronic systems (“denial of services”), loss or theft of proprietary information or corporate data, physical damage to a computer or network system, or costs associated with system repairs. Such incidents could cause the Fund, the advisor, a manager, or other service providers to incur regulatory penalties, reputational damage, additional compliance costs, or financial loss. In addition, such incidents could affect issuers in which the Fund invests, and thereby cause the Fund’s investments to lose value.

INVESTMENT AND MARKET RISK

An investment in Common Shares is subject to investment and market risk, including the possible loss of the entire principal amount invested. An investment in Common Shares represents an indirect investment in the securities owned by the Fund, which generally are traded on a securities exchange or in the over-the-counter markets. The value of these securities, like other market investments, may move up or down, sometimes rapidly and unpredictably. Common Shares at any point in time may be worth less than the original investment, even after taking into account any reinvestment of dividends and distributions.

TAX RISK

To qualify for the special tax treatment available to regulated investment companies, the Fund must: (i) derive at least 90% of its annual gross income from certain kinds of investment income; (ii) meet certain asset diversification requirements at the end of each quarter; and (iii) distribute in each taxable year at least 90% of its net investment income (including net interest income and net short term capital gain). If the Fund failed to meet any of these requirements, subject to the opportunity to cure such failures under applicable provisions of the Code, the Fund would be subject to U.S. federal income tax at regular corporate rates on its taxable income, including its net capital gain, even if such income were distributed to its shareholders. All distributions by the Fund from earnings and profits, including distributions of net capital gain (if any), would be taxable to the shareholders as ordinary income. Such distributions generally would be eligible (i) to be treated as qualified dividend income in the case of individual and other non-corporate shareholders and (ii) for the dividends received deduction in the case of corporate shareholders, provided that in each case the shareholder meets applicable holding period requirements. In addition, in order to requalify for taxation as a regulated investment company, the Fund might be required to recognize unrealized gain, pay substantial taxes and interest, and make certain distributions. See “U.S. Federal Income Tax Matters.”

The tax treatment and characterization of the Fund’s distributions may vary significantly from time to time due to the nature of the Fund’s investments. The ultimate tax characterization of the Fund’s distributions in a calendar year may not finally be determined until after the end of that calendar year. The Fund may make distributions during a calendar year that exceed the Fund’s current and accumulated earnings and profits for that year. In such a situation, the amount by which the Fund’s total distributions exceed the Fund’s current and accumulated earnings and profits generally would be treated as a return of capital up to the amount of the Common Shareholder’s tax basis in his or her Common Shares, with any amounts exceeding such basis treated as gain from the sale of his or her Common Shares. The Fund’s income distributions that qualify for favorable tax treatment may be affected by Internal Revenue Service (“IRS”) interpretations of the Code and future changes in tax laws and regulations. For instance, Congress is considering numerous proposals to decrease the federal budget deficit, some of which include further increasing U.S. federal income taxes or decreasing certain favorable tax treatments currently included in the Code. See “U.S. Federal Income Tax Matters.”

No assurance can be given as to what percentage of the distributions paid on Common Shares, if any, will consist of long-term capital gain or what the tax rates on various types of income will be in future years. See “U.S. Federal Income Tax Matters.”

DISTRIBUTION RISK

There can be no assurance that quarterly distributions paid by the Fund to shareholders will be maintained at current levels or increase over time. The quarterly distributions shareholders receive from the Fund are derived from the Fund’s dividends and interest income after payment of Fund expenses, net option premiums and net realized gain on equity securities investments. If stock market volatility and/or stock prices decline, the premiums available from writing call options and writing put options on individual stocks likely will decrease as well. Payments to purchase put options and to close written call and put options will reduce amounts available for distribution. Net realized gain on the Fund’s stock investments will be determined primarily by the direction and movement of the stock market and the equity securities held. The Fund’s cash available for distribution may vary widely over the short- and long-term. If, for any calendar year, the total distributions made exceed the Fund’s net investment taxable income and net capital gain, the excess generally will be treated as a return of capital to each Common Shareholder (up to the amount of the Common Shareholder’s basis in his or her Common Shares) and thereafter as gain from the sale of Common Shares. The amount treated as a return of capital reduces the Common Shareholder’s adjusted basis in his or her Common Shares, thereby increasing his or her potential gain or reducing his or her potential loss on the subsequent sale of his or her Common Shares. Distributions in any year may include a substantial return of capital component. Dividends on common stocks are not fixed but are declared at the discretion of the issuer’s board of directors.

PORTFOLIO TURNOVER RISK

The Fund may engage in short-term trading strategies, and securities may be sold without regard to the length of time held when, in the opinion of the Subadvisor, investment considerations warrant such action. Higher rates of portfolio turnover likely would result in higher brokerage commissions and may generate short-term capital gain taxable as ordinary income, which may have a negative impact on the Fund’s performance over time. The portfolio turnover rate of the Fund may vary from year to year, as well as within a year.

DEFENSIVE POSITIONS RISK

During periods of adverse market or economic conditions, the Fund may temporarily invest all or a substantial portion of its total assets in short-term money market instruments, securities with remaining maturities of less than one year, cash or cash equivalents. The Fund will not be pursuing its investment objectives in these circumstances and could miss favorable market developments.

INTEREST RATE RISK

Interest rate risk is the risk that fixed-income securities such as debt securities and preferred securities will decline in value because of changes in market interest rates. When market interest rates rise, the market value of such securities generally will fall. The Fund’s investments in debt securities and preferred securities means that the NAV and market price of the Common Shares will tend to decline if market interest rates rise. Given the historically low level of interest rates in recent years and the likelihood that interest rates will increase when the national economy strengthens, the risk of the potentially negative impact of rising interest rates on the value of the Fund’s portfolio

may be significant. In addition, the longer the average maturity of the Fund’s portfolio of debt securities, the greater the potential impact of rising interest rates on the value of the Fund’s portfolio and the less flexibility the Fund may have to respond to the decreasing spread between the yield on its portfolio securities.

During periods of declining interest rates, an issuer may exercise its option to prepay principal of debt securities or to redeem preferred securities 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 lock in a below market interest rate, increase the security’s duration and reduce the value of the security. This is known as extension risk.

INFLATION RISK

Inflation risk is the risk that the purchasing power 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 Common Shares and distributions thereon can decline.

LEVERAGE RISK

By leveraging its investment portfolio, the Fund creates an opportunity for increased net income or capital appreciation. However, the use of leverage also involves risks, which can be significant. These risks include the possibility that the value of the assets acquired with such borrowing decreases although the Fund’s liability is fixed, greater volatility in the Fund’s NAV and the market price of the Fund’s Common Shares and higher expenses. Since the Advisor’s fee is based upon a percentage of the Fund’s managed assets, the Advisor’s fee will be higher if the Fund is leveraged and the Advisor will have an incentive to leverage the Fund. The Board will monitor this potential conflict. The Advisor intends to leverage the Fund only when it believes that the potential return on the additional investments acquired through the use of leverage is likely to exceed the costs incurred in connection with the offering.

The Fund is authorized to utilize leverage through borrowings, reinvestment of securities lending collateral or repurchase agreement proceeds, and/or the issuance of preferred shares, including the issuance of debt securities. The Fund is party to the LA as described in “—Description of Capital Structure—Liquidity Facility.”

The Fund utilizes the LA to increase its assets available for investment. When the Fund leverages its assets, Common Shareholders bear the fees associated with the liquidity facility and have the potential to benefit or be disadvantaged from the use of leverage. In addition, the fee paid to the Advisor is calculated on the basis of the Fund’s average daily managed assets, including proceeds from borrowings and/or the issuance of preferred shares, so the fee will be higher when leverage is utilized, which may create an incentive for the Advisor to employ financial leverage. Consequently, the Fund and the Advisor may have differing interests in determining whether to leverage the Fund’s assets. Leverage creates risks that may adversely affect the return for the Common Shareholders, including:

To the extent the returns derived from securities purchased with proceeds received from leverage exceed the cost of leverage, the Fund’s distributions may be greater than if leverage had not been used. Conversely, if the returns from the securities purchased with such proceeds are not sufficient to cover the cost of leverage, the amount available for distribution to Common Shareholders will be less than if leverage had not been used. In the latter case, the Advisor, in its best judgment, may nevertheless determine to maintain the Fund’s leveraged position if it deems such action to be appropriate. The costs of a borrowing program and/or an offering of preferred shares would be borne by Common Shareholders and consequently would result in a reduction of the NAV of Common Shares.

In addition to the risks created by the Fund’s use of leverage, the Fund is subject to the risk that the liquidity facility agreement is terminated due to the occurrence of one or more events of default under the LA. If the LA is terminated in such circumstances, the Fund would be subject to additional risk that it would be unable to timely, or at all, obtain replacement financing. The Fund might also be required to de-leverage, selling securities at a potentially inopportune time and incurring tax consequences. Further, the Fund’s ability to generate income from the use of leverage would be adversely affected.

The Fund may be required to maintain minimum average balances in connection with borrowings or to pay a commitment or other fee to maintain a liquidity facility; either of these requirements will increase the cost of borrowing over the stated interest rate. To the extent that the Fund borrows through the use of reverse repurchase agreements, it would be subject to a risk that the value of the portfolio securities transferred may substantially exceed the purchase price received by the Fund under the reverse repurchase agreement transaction. Alternatively, during the life of any reverse repurchase agreement transaction, the Fund may be required to transfer additional securities if the market value of those securities initially transferred declines. In addition, capital raised through borrowing or the issuance of preferred shares will be subject to interest costs or dividend payments that may or may not exceed the income and appreciation on the assets purchased. The issuance of additional classes of preferred shares involves offering expenses and other costs, which will be borne by the Common Shareholders, and may limit the Fund’s freedom to pay dividends on Common Shares or to engage in other activities.

The Fund may be subject to certain restrictions on investments imposed by guidelines of one or more nationally recognized statistical rating organizations which may issue ratings for the preferred shares or short-term debt instruments issued by the Fund. These guidelines may impose asset coverage or portfolio composition requirements that are more stringent than those imposed by the 1940 Act. Certain types of borrowings may result in the Fund being subject to covenants in credit agreements, including those relating to asset coverage, borrowing base and portfolio composition requirements and additional covenants that may affect the Fund’s ability to pay dividends and distributions on Common Shares in certain instances. The Fund also may be required to pledge its assets to the lenders in connection with certain types of borrowing. Under the current LA, the Fund is subject to covenants that include, but are not limited to, certain minimum net asset value and collateral requirements, as well as a requirement to provide timely certain financial information to the lender. The Advisor does not anticipate that these covenants or restrictions will adversely affect its ability to manage the Fund’s portfolio in accordance with the Fund’s investment objectives and principal investment strategies. Due to these covenants or restrictions, the Fund may be forced to liquidate investments at times and at prices that are not favorable to the Fund, or the Fund may be forced to forego investments that the Advisor otherwise views as favorable.

The extent that the Fund employs leverage, if any, will depend on many factors, the most important of which are investment outlook, market conditions and interest rates. Successful use of a leveraging strategy depends on the Advisor’s ability to predict correctly interest rates and market movements. There is no assurance that a leveraging strategy will be successful during any period in which it is employed.

MARKET DISCOUNT RISK

The Fund’s Common Shares will be offered only when Common Shares of the Fund are trading at a price equal to or above the Fund’s NAV per Common Share plus the per Common Share amount of commissions. As with any security, the market value of the Common Shares may increase or decrease from the amount initially paid for the Common Shares. The Fund’s Common Shares have traded at both a premium and at a discount to NAV. The shares of closed-end management investment companies frequently trade at a discount from their NAV. This characteristic is a risk separate and distinct from the risk that the Fund’s NAV could decrease as a result of investment activities. Investors bear a risk of loss to the extent that the price at which they sell their shares is lower in relation to the Fund’s NAV than at the time of purchase, assuming a stable NAV.

SECONDARY MARKET FOR THE COMMON SHARES

The issuance of new Common Shares may have an adverse effect on the secondary market for the Common Shares. When Common Shares are trading at a premium, the Fund may issue new Common Shares of the Fund. The increase in the amount of the Fund’s outstanding Common Shares resulting from the offering of new Common Shares may put downward pressure on the market price for the Common Shares of the Fund. Common Shares will

not be issued at any time when Common Shares are trading at a price lower than a price equal to the Fund’s NAV per Common Share plus the per Common Share amount of commissions.

The Fund also issues Common Shares through its dividend reinvestment plan. Common Shares may be issued under the plan at a discount to the market price for such Common Shares, which may put downward pressure on the market price for Common Shares of the Fund.

The voting power of current Common Shareholders will be diluted to the extent that such shareholders do not purchase shares in any future Common Share offerings or do not purchase sufficient shares to maintain their percentage interest. In addition, if the proceeds of such offering are unable to be invested as intended, the Fund’s per Common Share distribution may decrease (or may consist of return of capital) and the Fund may not participate in market advances to the same extent as if such proceeds were fully invested as planned.

MANAGEMENT RISK

The Fund is subject to management risk because it relies on the Subadvisor’s ability to pursue the Fund’s investment objectives. The Subadvisor applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that it will produce the desired results. The Subadvisor’s securities selections and other investment decisions might produce a loss or cause the Fund to underperform when compared to other funds with similar investment goals. If one or more key individuals leave the employ of the Subadvisor, then the Subadvisor may not be able to hire qualified replacements, or may require an extended time to do so. This could prevent the Fund from achieving its investment objectives.

ECONOMIC AND MARKET EVENTS RISK

Events in the financials sector historically have resulted, and may result from time to time, in an unusually high degree of volatility in the financial markets, both domestic and foreign. These events have included, but are not limited to: bankruptcies, corporate restructurings, and other events related to the sub-prime mortgage crisis in 2008; financial distress in the U.S. auto industry; credit and liquidity issues involving certain money market mutual funds; governmental efforts to limit short selling and high frequency trading; measures to address U.S. federal and state budget deficits; social, political and economic instability in Europe; Standard and Poor’s Ratings Services’ downgrade of U.S. long-term sovereign debt; economic stimulus by the Japanese central bank; steep declines in oil prices; dramatic changes in currency exchange rates; and China’s economic slowdown. Global economies and financial markets are becoming increasingly interconnected, which increases the possibility that conditions in one country or region might adversely impact issuers in a different country or region. Both domestic and foreign equity markets have experienced increased volatility and turmoil, with issuers that have exposure to the real estate, mortgage, and credit markets particularly affected, and it is uncertain when these conditions will recur. Banks and financial services companies could suffer losses if interest rates were to rise or economic conditions deteriorate.

In addition to financial market volatility, relatively high market volatility and reduced liquidity in credit and fixed-income markets may adversely affect many issuers worldwide. Actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, such as decreases or increases in short-term interest rates, or interventins in currency markets could cause high volatility in the equity and fixed-income markets. This reduced liquidity may result in less money being available to purchase raw materials, goods, and services from emerging markets, which may, in turn, bring down the prices of these economic staples. It may also result in emerging-market issuers having more difficulty obtaining financing, which may, in turn, cause a decline in their securities prices. These events and the possible resulting market volatility may have an adverse effect on the Fund’s performance.

Political turmoil within the United States and abroad may also impact the Fund. Although the U.S. government has honored its credit obligations, it remains possible that the United States could default on its obligations. While it is impossible to predict the consequences of such an unprecedented event, it is likely that a default by the United States would be highly disruptive to the U.S. and global securities markets and could significantly impair the value of the Fund’s investments. Similarly, political events within the United States at times have resulted, and may in the future result, in a shutdown of government services, which could negatively affect the U.S. economy, decrease the value of many fund investments, and increase uncertainty in or impair the operation of the U.S. or other securities markets.

Uncertainties surrounding the sovereign debt of a number of European Union (EU) countries and the viability of the EU have disrupted and may in the future disrupt markets in the United States and around the world. If one or more countries leave the EU or the EU dissolves, the world’s securities markets likely will be significantly disrupted.

Political and military events, including the military crises in Ukraine and the Middle East, and nationalist unrest in Europe, also may cause market disruptions.

In addition, there is a risk that the prices of goods and services in the U.S. and many foreign economies may decline over time, known as deflation. Deflation may have an adverse effect on stock prices and creditworthiness and may make defaults on debt more likely. If a country’s economy slips into a deflationary pattern, it could last for a prolonged period and may be difficult to reverse.

NATURAL DISASTERS AND ADVERSE WEATHER CONDITIONS

Certain areas of the world historically have been prone to major natural disasters, such as hurricanes, earthquakes, typhoons, flooding, tidal waves, tsunamis, erupting volcanoes, wildfires or droughts, and have been economically sensitive to environmental events. Such disasters, and the resulting damage, could have a severe and negative impact on the Fund’s investment portfolio and, in the longer term, could impair the ability of issuers in which the Fund invests to conduct their businesses in the manner normally conducted. Adverse weather conditions also may have a particularly significant negative effect on issuers in the agricultural sector and on insurance companies that insure against the impact of natural disasters.

CHANGES IN U.S. LAW

Changes in the state and U.S. federal laws applicable to the Fund, including changes to state and U.S. federal tax laws, or applicable to the Advisor, the Subadvisor and other securities or instruments in which the Fund may invest, may negatively affect the Fund’s returns to Common Shareholders. The Fund may need to modify its investment strategy in the future in order to satisfy new regulatory requirements or to compete in a changed business environment.

ANTI-TAKEOVER PROVISIONS

The Fund’s Declaration of Trust includes provisions that could limit the ability of other persons or entities to acquire control of the Fund or to change the composition of its Board. These provisions may deprive shareholders of opportunities to sell their Common Shares at a premium over the then current market price of the Common Shares. See “Certain Provisions in the Declaration of Trust and By-Laws—Anti-takeover provisions.”

Strategy Risks

CREDIT AND COUNTERPARTY RISK

This is the risk that the issuer or guarantor of a fixed-income security, the counterparty to an over-the-counter (OTC) derivatives contract (see “Hedging, derivatives, and other strategic transactions risk”), or a borrower of the Fund’s securities will be unable or unwilling to make timely principal, interest, or settlement payments, or otherwise honor its obligations. Credit risk associated with investments in fixed-income securities relates to the ability of the issuer to make scheduled payments of principal and interest on an obligation. A fund that invests in fixed-income securities is subject to varying degrees of risk that the issuers of the securities will have their credit ratings downgraded or will default, potentially reducing the fund’s share price and income level. Nearly all fixed-income securities are subject to some credit risk, which may vary depending upon whether the issuers of the securities are corporations, domestic or foreign governments, or their subdivisions or instrumentalities. U.S. government securities are subject to varying degrees of credit risk depending upon whether the securities are supported by the full faith and credit of the United States; the ability to borrow from the U.S. Treasury; only by the credit of the issuing U.S. government agency, instrumentality, or corporation; or otherwise supported by the United States. For example, issuers of many types of U.S. government securities (e.g., the Federal Home Loan Mortgage Corporation (Freddie Mac), Federal National Mortgage Association (Fannie Mae), and Federal Home Loan Banks), although chartered or sponsored by Congress, are not funded by congressional appropriations, and their fixed-income securities, including asset-backed and mortgage-backed securities, are neither guaranteed nor insured by the U.S. government. An agency of the U.S. government has placed Fannie Mae and Freddie Mac into conservatorship, a statutory process with the objective of returning the entities to normal business operations. It is unclear what effect this conservatorship will have on the securities issued or guaranteed by Fannie Mae or Freddie Mac. As a result, these securities are subject to more credit risk than U.S. government securities that are supported by the full faith and credit of the United States (e.g., U.S. Treasury bonds). When a fixed-income security is not rated, a manager may have to assess the risk of the security itself. Asset-backed securities, whose principal and

interest payments are supported by pools of other assets, such as credit card receivables and automobile loans, are subject to further risks, including the risk that the obligors of the underlying assets default on payment of those assets.

Funds that invest in below-investment-grade securities, also called junk bonds (e.g., fixed-income securities rated Ba or lower by Moody’s Investors Service, Inc. or BB or lower by Standard & Poor’s Ratings Services, at the time of investment, or determined by a manager to be of comparable quality to securities so rated) are subject to increased credit risk. The sovereign debt of many foreign governments, including their subdivisions and instrumentalities, falls into this category. Below-investment-grade securities offer the potential for higher investment returns than higher-rated securities, but they carry greater credit risk: their issuers’ continuing ability to meet principal and interest payments is considered speculative, they are more susceptible to real or perceived adverse economic and competitive industry conditions, and they may be less liquid than higher-rated securities.

In addition, the Fund is exposed to credit risk to the extent that it makes use of OTC derivatives (such as forward foreign currency contracts and/or swap contracts) and engages to a significant extent in the lending of fund securities or the use of repurchase agreements. OTC derivatives transactions can be closed out with the other party to the transaction. If the counterparty defaults, the Fund will have contractual remedies, but there is no assurance that the counterparty will be able to meet its contractual obligations or that, in the event of default, the Fund will succeed in enforcing them. The Fund, therefore, assumes the risk that it may be unable to obtain payments owed to it under OTC derivatives contracts or that those payments may be delayed or made only after the Fund has incurred the costs of litigation. While the manager intends to monitor the creditworthiness of contract counterparties, there can be no assurance that the counterparty will be in a position to meet its obligations, especially during unusually adverse market conditions.

CORPORATE DEBT SECURITIES RISK

Corporate debt obligations are subject to the risk of an issuer’s inability to meet principal and interest payments on the obligations and also may be subject to price volatility due to such factors as market interest rates, market perception of the creditworthiness of the issuer and general market liquidity.

U.S. GOVERNMENT SECURITIES RISK

The Fund may invest in U.S. government securities issued or guaranteed by the U.S. government or by an agency or instrumentality of the U.S. government. Not all U.S. government securities are backed by the full faith and credit of the United States. Some are supported only by the credit of the issuing agency or instrumentality, which depends entirely on its own resources to repay the debt. U.S. government securities that are backed by the full faith and credit of the United States include U.S. Treasuries and mortgage-backed securities guaranteed by the Government National Mortgage Association. Securities that are only supported by the credit of the issuing agency or instrumentality include Fannie Mae, FHLBs and Freddie Mac. See “Credit and counterparty risk” for additional information on Fannie Mae and Freddie Mac securities.

FIXED-INCOME SECURITIES RISK

Fixed-income securities are generally subject to two principal types of risk, as well as other risks described below: (1) interest-rate risk and (2) credit quality risk.

Interest-rate risk. Fixed-income securities are affected by changes in interest rates. When interest rates decline, the market value of fixed-income securities generally can be expected to rise. Conversely, when interest rates rise, the market value of fixed-income securities generally can be expected to decline. The longer the duration or maturity of a fixed-income security, the more susceptible it is to interest-rate risk.

Credit quality risk. Fixed-income securities are subject to the risk that the issuer of the security will not repay all or a portion of the principal borrowed and will not make all interest payments. If the credit quality of a fixed-income security deteriorates after the Fund has purchased the security, the market value of the security may decrease and lead to a decrease in the value of the Fund’s investments. An issuer’s credit quality could deteriorate as a result of poor management decisions, competitive pressures, technological obsolescence, undue reliance on suppliers, labor issues, shortages, corporate restructurings, fraudulent disclosures, or other factors. Funds that may invest in lower-rated fixed-income securities, commonly referred to as junk securities, are riskier than funds that

may invest in higher-rated fixed-income securities. Additional information on the risks of investing in investment-grade fixed-income securities in the lowest rating category and lower-rated fixed-income securities is set forth below.

Investment-grade fixed-income securities in the lowest rating category risk. Investment-grade fixed-income securities in the lowest rating category (such as Baa by Moody’s Investors Service, Inc. or BBB by Standard and Poor’s Ratings Services and comparable unrated securities) involve a higher degree of risk than fixed-income securities in the higher rating categories. While such securities are considered investment-grade quality and are deemed to have adequate capacity for payment of principal and interest, such securities lack outstanding investment characteristics and have speculative characteristics as well. For example, changes in economic conditions or other circumstances are more likely to lead to a weakened capacity to make principal and interest payments than is the case with higher-grade securities.

Prepayment of principal risk. Many types of debt securities, including floating-rate loans, are subject to prepayment risk. Prepayment risk occurs when the issuer of a security can repay principal prior to the security’s maturity. Securities subject to prepayment risk can offer less potential for gains when the credit quality of the issuer improves.

Additional risks regarding lower-rated foreign government fixed-income securities. Lower-rated foreign government fixed-income securities are subject to the risks of investing in foreign countries described under “Foreign securities risk.” In addition, the ability and willingness of a foreign government to make payments on debt when due may be affected by the prevailing economic and political conditions within the country. Emerging-market countries may experience high inflation, interest rates, and unemployment, as well as exchange-rate fluctuations which adversely affect trade and political uncertainty or instability. These factors increase the risk that a foreign government will not make payments when due.

Recent Fixed-Income Market Events. In addition to financial market volatility, relatively high market volatility and reduced liquidity in credit and fixed-income markets may adversely affect many issuers worldwide. Actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, such as decreases or increases in short-term interest rates, or interventions in currency markets, could cause high volatility in the equity and fixed-income markets.

LOWER-RATED AND HIGH-YIELD FIXED-INCOME SECURITIES RISK

Lower-rated fixed-income securities and high-yield fixed-income securities (commonly known as “junk bonds”) are subject to the same risks as other fixed-income securities but have greater credit quality risk and may be considered speculative. In addition, lower-rated corporate debt securities (and comparable unrated securities) tend to be more sensitive to individual corporate developments and changes in economic conditions than higher-rated corporate fixed-income securities. Issuers of lower-rated corporate debt securities may also be highly leveraged, increasing the risk that principal and income will not be repaid. Lower-rated foreign government fixed-income securities are subject to the risks of investing in foreign countries described under “Foreign securities risk.” In addition, the ability and willingness of a foreign government to make payments on debt when due may be affected by the prevailing economic and political conditions within the country. Emerging-market countries may experience high inflation, interest rates and unemployment, as well as exchange rate fluctuations which adversely affect trade and political uncertainty or instability. These factors increase the risk that a foreign government will not make payments when due.

Lower-rated fixed-income securities are defined as securities rated below investment grade (such as Ba and below by Moody’s Investors Service, Inc. and BB and below by Standard and Poor’s Ratings Services) (also called junk bonds). The general risks of investing in these securities are as follows:

Risk to principal and income. Investing in lower-rated fixed-income securities is considered speculative. While these securities generally provide greater income potential than investments in higher-rated securities, there is a greater risk that principal and interest payments will not be made. Issuers of these securities may even go into default or become bankrupt.

Price volatility. The price of lower-rated fixed-income securities may be more volatile than securities in the higher-rated categories. This volatility may increase during periods of economic uncertainty or change. The price of these

securities is affected more than higher-rated fixed-income securities by the market’s perception of their credit quality, especially during times of adverse publicity. In the past, economic downturns or increases in interest rates have, at times, caused more defaults by issuers of these securities and may do so in the future. Economic downturns and increases in interest rates have an even greater effect on highly leveraged issuers of these securities.

Liquidity. The market for lower-rated fixed-income securities may have more limited trading than the market for investment-grade fixed-income securities. Therefore, it may be more difficult to sell these securities, and these securities may have to be sold at prices below their market value in order to meet redemption requests or to respond to changes in market conditions.

Dependence on manager’s own credit analysis. While a manager may rely on ratings by established credit rating agencies, it will also supplement such ratings with its own independent review of the credit quality of the issuer. Therefore, the assessment of the credit risk of lower-rated fixed-income securities is more dependent on the manager’s evaluation than the assessment of the credit risk of higher-rated securities.

Additional risks regarding lower-rated corporate fixed-income securities. Lower-rated corporate fixed-income securities (and comparable unrated securities) tend to be more sensitive to individual corporate developments and changes in economic conditions than higher-rated corporate fixed-income securities. Issuers of lower-rated corporate fixed-income securities may also be highly leveraged, increasing the risk that principal and income will not be repaid.

MORTGAGE-BACKED AND ASSET-BACKED SECURITIES RISK

Mortgage-backed securities. Mortgage-backed securities represent participating interests in pools of residential mortgage loans, which are guaranteed by the U.S. government, its agencies, or its instrumentalities. However, the guarantee of these types of securities relates to the principal and interest payments, and not to the market value of such securities. In addition, the guarantee only relates to the mortgage-backed securities held by a fund and not the purchase of shares of a fund.

Mortgage-backed securities are issued by lenders, such as mortgage bankers, commercial banks, and savings and loan associations. Such securities differ from conventional debt securities, which provide for the periodic payment of interest in fixed amounts (usually semiannually) with principal payments at maturity or on specified dates. Mortgage-backed securities provide periodic payments which are, in effect, a pass through of the interest and principal payments (including any prepayments) made by the individual borrowers on the pooled mortgage loans. A mortgage-backed security will mature when all the mortgages in the pool mature or are prepaid. Therefore, mortgage-backed securities do not have a fixed maturity and their expected maturities may vary when interest rates rise or fall.

When interest rates fall, homeowners are more likely to prepay their mortgage loans. An increased rate of prepayments on the Fund’s mortgage-backed securities will result in an unforeseen loss of interest income to the Fund as the Fund may be required to reinvest assets at a lower interest rate. Because prepayments increase when interest rates fall, the prices of mortgage-backed securities do not increase as much as other fixed-income securities when interest rates fall.

When interest rates rise, homeowners are less likely to prepay their mortgage loans. A decreased rate of prepayments lengthens the expected maturity of a mortgage-backed security. Therefore, the prices of mortgage-backed securities may decrease more than prices of other fixed-income securities when interest rates rise.

The yield of mortgage-backed securities is based on the average life of the underlying pool of mortgage loans. The actual life of any particular pool may be shortened by unscheduled or early payments of principal and interest. Principal prepayments may result from the sale of the underlying property, or the refinancing or foreclosure of underlying mortgages. The occurrence of prepayments is affected by a wide range of economic, demographic, and social factors, and, accordingly, it is not possible to accurately predict the average life of a particular pool. The actual prepayment experience of a pool of mortgage loans may cause the yield realized by the Fund to differ from the yield calculated on the basis of the average life of the pool. In addition, if the Fund purchases mortgage-backed securities at a premium, the premium may be lost in the event of early prepayment, which may result in a loss to the Fund.

Prepayments tend to increase during periods of falling interest rates, while during periods of rising interest rates, prepayments are likely to decline. Monthly interest payments received by the Fund have a compounding effect, which will increase the yield to shareholders as compared with debt obligations that pay interest semiannually. Because of the reinvestment of prepayments of principal at current rates, mortgage-backed securities may be less effective than U.S. Treasury bonds of similar maturity at maintaining yields during periods of declining interest rates. Also, although the value of debt securities may increase as interest rates decline, the value of these pass through types of securities may not increase as much, due to their prepayment feature.

Collateralized mortgage obligations (CMOs). The Fund may invest in mortgage-backed securities called CMOs. CMOs are issued in separate classes with different stated maturities. As the mortgage pool experiences prepayments, the pool pays off investors in classes with shorter maturities first. By investing in CMOs, the Fund may manage the prepayment risk of mortgage-backed securities. However, prepayments may cause the actual maturity of a CMO to be substantially shorter than its stated maturity.

Asset-backed securities. Asset-backed securities include interests in pools of debt securities, commercial or consumer loans, or other receivables. The value of these securities depends on many factors, including changes in interest rates, the availability of information concerning the pool and its structure, the credit quality of the underlying assets, the market’s perception of the servicer of the pool, and any credit enhancement provided. In addition, asset-backed securities have prepayment risks similar to mortgage-backed securities.

Mortgage Dollar Rolls. Under a mortgage dollar roll, the Fund sells mortgage-backed securities for delivery in the future (generally within 30 days) and simultaneously contracts to repurchase substantially similar (same type, coupon and maturity) securities on a specified future date. 

At the time the Fund enters into a mortgage dollar roll, it will maintain on its records liquid assets such as cash or U.S. government securities equal in value to its obligations in respect of dollar rolls, and accordingly, such dollar rolls will not be considered borrowings.

The Fund may only enter into covered rolls. A “covered roll” is a specific type of dollar roll for which there is an offsetting cash or cash equivalent security position that matures on or before the forward settlement date of the dollar roll transaction. Dollar roll transactions involve the risk that the market value of the securities sold by the Fund may decline below the repurchase price of those securities. While a mortgage dollar roll may be considered a form of leveraging, and may, therefore, increase fluctuations in the Fund’s NAV per share, the Fund will cover the transaction as described above.

EQUITY SECURITIES RISK

Common and preferred stocks represent equity ownership in a company. Stock markets are volatile. The price of equity securities will fluctuate, and can decline and reduce the value of the Fund investing in equities. The price of equity securities fluctuates based on changes in a company’s financial condition and overall market and economic conditions. The value of equity securities purchased by the Fund could decline if the financial condition of the companies in which the Fund is invested declines, or if overall market and economic conditions deteriorate. An issuer’s financial condition could decline as a result of poor management decisions, competitive pressures, technological obsolescence, undue reliance on suppliers, labor issues, shortages, corporate restructurings, fraudulent disclosures, or other factors. Changes in the financial condition of a single issuer can impact the market as a whole.

Even a fund that invests in high-quality, or blue chip, equity securities, or securities of established companies with large market capitalizations (which generally have strong financial characteristics), can be negatively impacted by poor overall market and economic conditions. Companies with large market capitalizations may also have less growth potential than smaller companies and may be less able to react quickly to changes in the marketplace.

The Fund may maintain substantial exposure to equities and generally does not attempt to time the market. Because of this exposure, the possibility that stock market prices in general will decline over short or extended periods subjects the Fund to unpredictable declines in the value of its investments, as well as periods of poor performance.

Preferred and convertible securities risk. Unlike interest on debt securities, preferred stock dividends are payable only if declared by the issuer’s board. Also, preferred stock may be subject to optional or mandatory redemption provisions. The value of convertible preferred stock can depend heavily upon the value of the security into which

such convertible preferred stock is converted, depending on whether the market price of the underlying security exceeds the conversion price.

LIQUIDITY RISK

The extent to which a security may be sold or a derivative position closed without negatively impacting its market value, if at all, may be impaired by reduced market activity or participation, legal restrictions or other economic and market impediments. Funds with principal investment strategies that involve investments in securities of companies with smaller market capitalizations, foreign securities, derivatives, or securities with substantial market and/or credit risk tend to have the greatest exposure to liquidity risk. Exposure to liquidity risk may be heightened for funds that invest in securities of emerging markets and related derivatives that are not widely traded, and that may be subject to purchase and sale restrictions.

The capacity of traditional dealers to engage in fixed-income trading has not kept pace with the bond market’s growth. As a result, dealer inventories of corporate bonds, which indicate the ability to “make markets,” i.e., buy or sell a security at the quoted bid and ask price, respectively, are at or near historic lows relative to market size. Because market makers provide stability to fixed-income markets, the significant reduction in dealer inventories could lead to decreased liquidity and increased volatility, which may become exacerbated during periods of economic or political stress.

NON-U.S. INVESTMENT RISK

Funds that invest in securities traded principally in securities markets outside the U.S. are subject to additional and more varied risks, as the value of non-U.S. securities may change more rapidly and extremely than the value of U.S. securities. The securities markets of many foreign countries are relatively small, with a limited number of companies representing a small number of industries. Additionally, issuers of non-U.S. securities may not be subject to the same degree of regulation as U.S. issuers. Reporting, accounting and auditing standards of foreign countries differ, in some cases significantly, from U.S. standards. There generally are higher commission rates on non-U.S. portfolio transactions, transfer taxes, higher custodial costs and the possibility that non-U.S. taxes will be charged on dividends and interest payable on non-U.S. securities, some or all of which may not be reclaimable. Also, for lesser-developed countries, nationalization, expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations (which may include suspension of the ability to transfer currency or assets from a country), political changes or diplomatic developments could adversely affect the Fund’s investments. In the event of nationalization, expropriation or other confiscation, the Fund could lose its entire investment in a non-U.S. security. All funds that invest in non-U.S. securities are subject to these risks. Some of the non-U.S. investment risks also are applicable to funds that invest a material portion of their assets in securities of non-U.S. issuers traded in the U.S.

Currency risk. Currency risk is the risk that fluctuations in exchange rates may adversely affect the U.S. dollar value of the Fund’s investments. Currency risk includes both the risk that currencies in which the Fund’s investments are traded, or currencies in which the Fund has taken an active investment position, will decline in value relative to the U.S. dollar and, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency being hedged. Currency rates in foreign countries may fluctuate significantly for a number of reasons, including the forces of supply and demand in the foreign exchange markets, actual or perceived changes in interest rates, and intervention (or the failure to intervene) by U.S. or foreign governments or central banks, or by currency controls or political developments in the United States or abroad. Certain funds may engage in proxy hedging of currencies by entering into derivative transactions with respect to a currency whose value is expected to correlate to the value of a currency the Fund owns or wants to own. This presents the risk that the two currencies may not move in relation to one another as expected. In that case, the Fund could lose money on its investment and also lose money on the position designed to act as a proxy hedge. Certain funds may also take active currency positions and may cross-hedge currency exposure represented by their securities into another foreign currency. This may result in the Fund’s currency exposure being substantially different from that suggested by its securities investments. All funds with foreign currency holdings and/or that invest or trade in securities denominated in foreign currencies or related derivative instruments may be adversely affected by changes in foreign currency exchange rates. Derivative foreign currency transactions (such as futures, forwards, and swaps) may also involve leveraging risk, in addition to currency risk. Leverage may disproportionately increase the Fund’s portfolio losses and reduce opportunities for gain when interest rates, stock prices, or currency rates are changing.

SOVEREIGN DEBT OBLIGATIONS RISK

An investment in debt obligations of non-U.S. governments and their political subdivisions (sovereign debt), whether denominated in U.S. dollars or a foreign currency, involves special risks that are not present in corporate debt obligations. The non-U.S. issuer of the sovereign debt or the non-U.S. governmental authorities that control the repayment of the debt may be unable or unwilling to repay principal or pay interest when due, and the Fund may have limited recourse in the event of a default. During periods of economic uncertainty, the market prices of sovereign debt may be more volatile than prices of debt obligations of U.S. issuers. In the past, certain non-U.S. countries have encountered difficulties in servicing their debt obligations, withheld payments of principal and interest and declared moratoria on the payment of principal and interest on their sovereign debt. A sovereign debtor’s willingness or ability to repay principal and pay interest in a timely manner may be affected by, among other factors, its cash flow situation, the extent of its foreign currency reserves, the availability of sufficient foreign exchange, the relative size of the debt service burden, the sovereign debtor’s policy toward its principal international lenders and local political constraints. Sovereign debtors also may be dependent on expected disbursements from non-U.S. governments, multilateral agencies and other entities to reduce principal and interest arrearages on their debt. The failure of a sovereign debtor to implement economic reforms, achieve specified levels of economic performance or repay principal or interest when due may result in the cancellation of third-party commitments to lend funds to the sovereign debtor, which may further impair such debtor’s ability or willingness to service its debts.

BRADY BONDS RISK

Brady Bonds may involve a high degree of risk, may be in default or present the risk of default. Agreements implemented under the Brady Plan to date are designed to achieve debt and debt-service reduction through specific options negotiated by a debtor nation with its creditors. As a result, the financial packages offered by each country differ. The types of options have included the exchange of outstanding commercial bank debt for bonds issued at 100% of face value of such debt, bonds issued at a discount of face value of such debt, bonds bearing an interest rate which increases over time and bonds issued in exchange for the advancement of new money by existing lenders. Certain Brady Bonds have been collateralized as to principal due at maturity by U.S. Treasury zero coupon bonds with a maturity equal to the final maturity of such Brady Bonds, although the collateral is not available to investors until the final maturity of the Brady Bonds. Collateral purchases are financed by the IMF, the World Bank and the debtor nations’ reserves. In addition, the first two or three interest payments on certain types of Brady Bonds may be collateralized by cash or securities agreed upon by creditors. Although Brady Bonds may be collateralized by U.S. government securities, repayment of principal and interest is not guaranteed by the U.S. government.

REVERSE REPURCHASE AGREEMENT RISK

Reverse repurchase agreement transactions involve the risk that the market value of the securities that the Fund is obligated to repurchase under such agreements may decline below the repurchase price. Any fluctuations in the market value of either the securities transferred to the other party or the securities in which the proceeds may be invested would affect the market value of the Fund’s assets, thereby potentially increasing fluctuations in the market value of the Fund’s assets. In the event the buyer of securities under a reverse repurchase agreement files for bankruptcy or becomes insolvent, the Fund’s use of proceeds received under the agreement may be restricted pending a determination by the other party, or its trustee or receiver, whether to enforce the Fund’s obligation to repurchase the securities.

HEDGING, DERIVATIVES AND OTHER STRATEGIC TRANSACTIONS RISK

The ability of the Fund to utilize hedging, derivatives and other strategic transactions to benefit the Fund will depend in part on the Subadvisor’s ability to predict pertinent market movements and market risk, counterparty risk, credit risk, interest-rate risk and other risk factors, none of which can be assured. The skills required to utilize hedging and other strategic transactions are different from those needed to select the Fund’s securities. Even if the Subadvisor only uses hedging and other strategic transactions in the Fund primarily for hedging purposes or to gain exposure to a particular securities market, if the transaction does not have the desired outcome, it could result in a significant loss to the Fund. The amount of loss could be more than the principal amount invested. These transactions also may increase the volatility of the Fund and may involve a small investment of cash relative to the magnitude of the risks assumed, thereby magnifying the impact of any resulting gain or loss. For example, the potential loss from the use of futures can exceed the Fund’s initial investment in such contracts. In addition, these transactions could result in a loss to the Fund if the counterparty to the transaction does not perform as promised.

The Fund may invest in derivatives, which are financial contracts with a value that depends on, or is derived from, the value of underlying assets, reference rates or indexes. Examples of derivative instruments include options,

futures contracts, options on futures contracts, foreign currency forward contracts and swap agreements (including, but not limited to, interest-rate swaps, total return swaps, credit default swaps and swaps on exchange-traded funds). Examples of derivative instruments include currency forwards, futures (including currency futures), credit default swaps, options and market access products including zero strike options and zero strike warrants. Derivatives may relate to stocks, bonds, interest rates, currencies or currency exchange rates and related indexes. The Fund may use derivatives for many purposes, including for hedging, and as a substitute for direct investment in securities or other assets. Derivatives may be used in a way to efficiently adjust the exposure of the Fund to various securities, markets and currencies without the Fund actually having to sell existing investments and make new investments. This generally will be done when the adjustment is expected to be relatively temporary or in anticipation of effecting the sale of fund assets and making new investments over time. Further, since many derivatives have a leverage component, adverse changes in the value or level of the underlying asset, reference rate or index can result in a loss substantially greater than the amount invested in the derivative itself. Certain derivatives have the potential for unlimited loss, regardless of the size of the initial investment. When the Fund uses derivatives for leverage, investments in the Fund will tend to be more volatile, resulting in larger gain or loss in response to market changes. To limit leverage risk, the Fund may segregate assets determined to be liquid or, as permitted by applicable regulation, enter into certain offsetting positions to cover its obligations under derivative instruments. For a description of the various derivative instruments the Fund may utilize, refer to the SAI.

The regulation of the U.S. and non-U.S. derivatives markets has undergone substantial change in recent years and such change may continue. In particular, the Dodd-Frank Wall Street Reform and Consumer Protection Act, and regulation proposed to be promulgated thereunder require many derivatives to be cleared and traded on an exchange, expand entity registration requirements, impose business conduct requirements on dealers that enter into swaps with a pension plan, endowment, retirement plan or government entity, and required banks to move some derivatives trading units to a non-guaranteed affiliate separate from the deposit-taking bank or divest them altogether. Although the CFTC has released final rules relating to clearing, reporting, recordkeeping and registration requirements under the legislation, many of the provisions are subject to further final rule making, and thus its ultimate impact remains unclear. New regulations could, among other things, restrict the Fund’s ability to engage in derivatives transactions (for example, by making certain types of derivatives transactions no longer available to the Fund) and/or increase the costs of such derivatives transactions (for example, by increasing margin or capital requirements), and the Fund may be unable to fully execute its investment strategies as a result. Limits or restrictions applicable to the counterparties with which the Fund engages in derivative transactions also could prevent the Fund from using these instruments or affect the pricing or other factors relating to these instruments, or may change the availability of certain investments.

At any time after the date of this prospectus, legislation may be enacted that could negatively affect the assets of the Fund. Legislation or regulation may change the way in which the Fund itself is regulated. The Adviser cannot predict the effects of any new governmental regulation that may be implemented, and there can be no assurance that any new governmental regulation will not adversely affect the Fund’s ability to achieve its investment objectives.

The use of derivative instruments may involve risks different from, or potentially greater than, the risks associated with investing directly in securities and other, more traditional assets. In particular, the use of derivative instruments exposes the Fund to the risk that the counterparty to an OTC derivatives contract will be unable or unwilling to make timely settlement payments or otherwise honor its obligations. OTC derivatives transactions typically can only be closed out with the other party to the transaction, although either party may engage in an offsetting transaction that puts that party in the same economic position as if it had closed out the transaction with the counterparty or may obtain the other party’s consent to assign the transaction to a third party. If the counterparty defaults, the Fund will have contractual remedies, but there is no assurance that the counterparty will meet its contractual obligations or that, in the event of default, the Fund will succeed in enforcing them. For example, because the contract for each OTC derivatives transaction is individually negotiated with a specific counterparty, the Fund is subject to the risk that a counterparty may interpret contractual terms (e.g., the definition of default) differently than the Fund when the Fund seeks to enforce its contractual rights. If that occurs, the cost and unpredictability of the legal proceedings required for the Fund to enforce its contractual rights may lead it to decide not to pursue its claims against the counterparty. The Fund, therefore, assumes the risk that it may be unable to obtain payments owed to it under OTC derivatives contracts or that those payments may be delayed or made only after the Fund has incurred the costs of litigation. While a manager intends to monitor the creditworthiness of counterparties, there can be no assurance that a counterparty will meet its obligations, especially during unusually adverse market conditions. To the extent the Fund contracts with a limited number of counterparties, the Fund’s risk will be concentrated and events that affect the creditworthiness of any of those counterparties may have a pronounced effect on the Fund. Derivatives are also subject to a number of other risks,

including market risk and liquidity risk. Since the value of derivatives is calculated and derived from the value of other assets, instruments, or references, there is a risk that they will be improperly valued. Derivatives also involve the risk that changes in their value may not correlate perfectly with the assets, rates, or indexes they are designed to hedge or closely track. Suitable derivatives transactions may not be available in all circumstances. The Fund is also subject to the risk that the counterparty closes out the derivatives transactions upon the occurrence of certain triggering events. In addition, a manager may determine not to use derivatives to hedge or otherwise reduce risk exposure. Government legislation or regulation could affect the use of derivatives transactions and could limit the Fund’s ability to pursue its investment strategies.

The following is a list of certain derivatives and other strategic transactions in which the Fund may invest and the main risks associated with each of them:

Given the risks described above, an investment in Common Shares may not be appropriate for all investors. You should carefully consider your ability to assume these risks before making an investment in the Fund.

Management of the Fund 

TRUSTEES

The overall management of the Fund, including supervision of the duties performed by the Advisor and the Subadvisor, is the responsibility of the Board under the laws of The Commonwealth of Massachusetts and the 1940 Act. The Trustees are responsible for the Fund’s overall management, including adopting the investment and other policies of the Fund, electing and replacing officers and selecting and supervising the Fund’s Advisor and Subadvisor. The names and business addresses of the Trustees and officers of the Fund and their principal occupations and other affiliations during the past five years, as well as a description of committees of the Board, are set forth under “Those Responsible for Management” in the SAI.

A discussion regarding the basis for the Trustees’ approval of the Advisory Agreement and the Subadvisory Agreement (each, as defined below) is available in the Fund’s most annual shareholder report for the fiscal year ended October 3.

THE ADVISOR

The Advisor, John Hancock Advisers, LLC, is a Delaware limited liability company whose principal offices are located at 601 Congress Street, Boston, Massachusetts 02210 and serves as the Fund’s investment advisor. The Advisor is registered with the SEC as an investment advisor under the Investment Advisers Act of 1940, as amended (the “Advisers Act”).

Founded in 1968, the Advisor is a wholly owned subsidiary of John Hancock Life Insurance Company (U.S.A.), a subsidiary of Manulife Financial Corporation (“Manulife Financial” or the “Company”). Manulife Financial is the holding company of The Manufacturers Life Insurance Company (the “Life Company”) and its subsidiaries. John Hancock Life Insurance Company (U.S.A.) and its subsidiaries (“John Hancock”) today offer a broad range of financial products and services, including whole, term, variable, and universal life insurance, as well as college savings products, mutual funds, fixed and variable annuities, long-term care insurance and various forms of business insurance.

The Advisor’s parent company has been helping individuals and institutions work toward their financial goals since 1862. The Advisor offers investment solutions managed by institutional money managers, taking a disciplined team approach to portfolio management and research, leveraging the expertise of seasoned investment professionals. The Advisor has been managing closed-end funds since 1971. As of December 31, 2015, the Advisor had total assets under management of approximately $131.5 billion.

Subject to general oversight by the Board of Trustees, the Advisor manages and supervises the investment operations and business affairs of the Fund. The Advisor selects, contracts with and compensates one or more subadvisors to manage on a day-to-day basis all or a portion of the Fund’s portfolio assets subject to oversight by the Advisor. The Advisor is responsible for overseeing and implementing the Fund’s investment program and provides a variety of advisory oversight and investment research services. The Advisor also provides management and transition services associated with certain fund events (e.g., strategy, portfolio manager or subadvisor changes) and coordinates and oversees services provided under other agreements.

Established in 1887, Manulife Financial is a Canada-based financial services group with principal operations in Asia, Canada and the U.S. Its international network of employees, agents and distribution partners offers financial protection and wealth management products and services to millions of clients. It also provides asset management services to institutional customers. Funds under management by Manulife Financial and its subsidiaries were C$ 935 billion (US$676 billion) as at December 31, 2015. The Company operates as Manulife Financial in Canada and Asia and primarily as John Hancock in the United States.

Advisory Agreement. The Fund entered into an investment management contract dated July 1, 2009 (the “Advisory Agreement”) with the Advisor. As compensation for its advisory services under the Advisory Agreement, the Advisor receives a fee from the Fund, calculated and paid daily, at an annual rate of the Fund’s average daily managed assets. “Managed assets” means, for the purposes of calculating the advisory fee, the total assets of the Fund (including any assets attributable to any leverage that may be outstanding) minus the sum of accrued liabilities (other than liabilities representing financial leverage). The liquidation preference of any preferred shares is not a liability.

Pursuant to the Advisory Agreement and subject to the general supervision of the Trustees, the Advisor selects, contracts with, and compensates the Subadvisor to manage the investments and determine the composition of the assets of the Fund. The Advisor does not itself manage any of the Fund’s portfolio assets but has ultimate responsibility to oversee the Subadvisor and recommend its hiring, termination and replacement. In this capacity, the Advisor monitors the Subadvisor’s management of the Fund’s investment operations in accordance with the investment objectives and related investment policies of the Fund, reviews the performance of the Subadvisor and reports periodically on such performance to the Board.

Service Agreement. The Fund entered into a management-related service contract dated July 1, 2009 and re-executed on January 1, 2014 (the “Service Agreement”) with JHA, under which the Fund receives Non-Advisory Services. These “Non-Advisory Services” include, but are not limited to, legal, tax, accounting, valuation, financial reporting and performance, compliance, service provider oversight, portfolio and cash management, project management office, EDGAR conversion and filing, graphic design, and other services that are not investment

advisory in nature. JHA is reimbursed for its costs in providing Non-Advisory Services to the Fund under the Service Agreement.

THE SUBADVISOR

Subadvisory Agreement. The Advisor entered into a Subadvisory Agreement dated December 31, 2005 with the Subadvisor (the “Subadvisory Agreement”). The Subadvisor is responsible for the day-to-day management of the Fund’s portfolio investments. The Subadvisor, organized in 1968, is a wholly owned subsidiary of John Hancock Life Insurance Company (U.S.A.) (a subsidiary of Manulife Financial, a publicly held, Canadian-based company). As of December 31, 2015, the Subadvisor had total assets under management of approximately $167.2 billion. The Subadvisor is located at 101 Huntington Avenue, Boston, Massachusetts 02199.

Under the terms of the Subadvisory Agreement, the Subadvisor is responsible for managing the investment and reinvestment of the assets of the Fund, subject to the supervision and control of the Board and the Advisor. For services rendered by the Subadvisor under the Subadvisory Agreement, the Advisor (and not the Fund) pays the Subadvisor a fee.

CUSTODIAN AND TRANSFER AGENT

The Fund’s portfolio securities are held pursuant to a custodian agreement between the Fund and State Street Corporation (“State Street”), State Street Financial Center, One Lincoln Street, Boston, Massachusetts 02111. Under the custodian agreement, State Street performs custody, foreign custody manager and fund accounting services.

Computershare, Inc., 480 Washington Boulevard, Jersey City, New Jersey, 07310-1900, is the transfer agent and dividend disbursing agent of the Fund.

Determination of Net Asset Value

The NAV of the Common Shares is determined once daily as of the close of regular trading of the NYSE (typically 4:00 P.M., Eastern Time) on each business day that the NYSE is open. On holidays or other days when the NYSE is closed, the NAV is not calculated.

The NAV is computed by dividing the total assets, minus liabilities by the number of Fund shares outstanding.

Distribution Policy

The Fund makes regular quarterly distributions to Common Shareholders sourced from the Fund’s cash available for distribution. “Cash available for distribution” consists of the Fund’s (i) investment company taxable income, which includes among other things, dividend and ordinary income after payment of Fund expenses, the excess of net short-term capital gain over net long-term capital loss, and income from certain hedging and interest rate transactions and (ii) net long-term capital gain (gain from the sale of capital assets held longer than one year). The Board may modify this distribution policy at any time without obtaining the approval of Common Shareholders.

Expenses of the Fund are accrued each day. To the extent that the Fund’s net investment income for any year exceeds the total quarterly distributions paid during the year, the Fund may make a special distribution at or near year-end of such excess amount as may be required. If it does, over time, all of the Fund’s investment company taxable income will be distributed.

If, for any calendar year, as discussed above, the total distributions made exceed the Fund’s net investment taxable income and net capital gain, the excess generally will be treated as a return of capital to each Common Shareholder (up to the amount of the Common Shareholder’s basis in his or her Common Shares) and thereafter as gain from the sale of Common Shares. The amount treated as a return of capital reduces the Common Shareholder’s adjusted basis in his or her Common Shares, thereby increasing his or her potential gain or reducing his or her potential loss on the subsequent sale of his or her Common Shares. Distributions in any year may include a substantial return of capital component.

Pursuant to the requirements of the 1940 Act, in the event the Fund makes distributions from sources other than income, a notice will accompany each quarterly distribution with respect to the estimated source of the distribution made. Such notices will describe the portion, if any, of the quarterly dividend which, in the Fund’s good faith judgment, constitutes long-term capital gain, short-term capital gain, net investment income or a return of capital. The actual character of such dividend distributions for U.S. federal income tax purposes, however, will only be determined finally by the Fund at the close of its fiscal year, based on the Fund’s full year performance and its actual net investment company taxable income and net capital gain for the year, which may result in a recharacterization of amounts distributed during such fiscal year from the characterization in the quarterly estimates.

At least annually, the Fund intends to distribute any net capital gain (which is the excess of net long-term capital gain over net short-term capital loss) or, alternatively, to retain all or a portion of the year’s net capital gain and pay U.S. federal income tax on the retained gain. As provided under U.S. federal tax law, Common Shareholders of record as of the end of the Fund’s taxable year will include their attributable share of the retained gain in their income for the year as a long-term capital gain, and will be entitled to a tax credit or refund for the tax deemed paid on their behalf by the Fund. The Fund may treat the cash value of tax credit and refund amounts in connection with retained capital gain as a substitute for equivalent cash distributions.

The tax treatment and characterization of the Fund’s distributions may vary substantially from time to time because of the varied nature of the Fund’s investments. If the Fund’s total quarterly distributions in any year exceed the amount of its net investment taxable income for the year, any such excess would be characterized as a return of capital for U.S. federal income tax purposes to the extent not designated as a capital gain dividend. Distributions in any year may include a substantial return of capital component. Under the 1940 Act, for any distribution that includes amounts from sources other than net income (calculated on a book basis), the Fund is required to provide Common Shareholders a written statement regarding the components of such distribution. Such a statement will be provided at the time of any distribution believed to include any such amounts. A return of capital is a distribution to Common Shareholders that is not attributable to the Fund’s earnings but, represents a return of part of the Common Shareholder’s investment. If the Fund’s distributions exceed the Fund’s current and accumulated earnings and profits, such excess will be treated first as a return of capital to the extent of the shareholder’s tax basis in Common Shares (thus reducing a shareholder’s adjusted tax basis in his or her Common Shares), and thereafter as capital gain assuming Common Shares are held as a capital asset. Upon the sale of Common Shares, a shareholder generally will recognize capital gain or loss equal to the difference between the amount realized on the sale and the shareholder’s

adjusted tax basis in Common Shares sold. For example, in year one, a Common Shareholder purchased 100 shares of the Fund at $10 per Share. In year two, the Common Shareholder received a $1-per-share return of capital distribution, which reduced the basis in each share by $1, to give the Common Shareholder an adjusted basis of $9 per share. In year three, the Common Shareholder sells the 100 shares for $15 per Share. Assuming no other transactions during this period, a Common Shareholder would have a capital gain in year three of $6 per share ($15 minus $9) for a total capital gain of $600.

The 1940 Act currently limits the number of times the Fund may distribute long-term capital gain in any tax year, which may increase the variability of the Fund’s distributions and result in certain distributions being composed more heavily of long-term capital gain eligible for favorable income tax rates. In the future, the Advisor may seek Board approval to implement a managed distribution plan for the Fund. The managed distribution plan would be implemented pursuant to an exemptive order previously granted by the SEC, which provides an exemption from Section 19(b) of the 1940 Act and Rule 19b-1 thereunder to permit the Fund to include long-term capital gain as a part of its regular distributions to Common Shareholders more frequently than would otherwise be permitted by the 1940 Act (generally once or twice per year). If the Fund implements a managed distribution plan, it would do so without a vote of the Common Shareholders.

Distribution rates are based on projected quarterly cash available for distribution, which may result in fluctuations in quarterly rates. As a result, the distributions paid by the Fund for any particular quarter may be more or less than the amount of cash available for distribution from that quarterly period. In certain circumstances, the Fund may be required to sell a portion of its investment portfolio to fund distributions. Distributions will reduce the Common Shares’ NAV.

Common Shareholders may automatically reinvest some or all of their distributions in additional Common Shares under the Fund’s dividend reinvestment plan. See “Dividend Reinvestment Plan.”

Dividend Reinvestment Plan

Pursuant to the Fund’s Dividend Reinvestment Plan (the “Plan”), distributions of dividends and capital gain are automatically reinvested in Common Shares by Computershare, Inc. (the “Plan Agent”). Every shareholder holding at least one full share of the Fund is automatically enrolled in the Plan. Shareholders who do not participate in the Plan will receive all distributions in cash.

If the Fund declares a dividend or distribution payable either in cash or in Common Shares and the market price of shares on the payment date for the distribution or dividend equals or exceeds the Fund’s NAV per share, the Fund will issue Common Shares to participants at a value equal to the higher of NAV or 95% of the market price. The number of additional Common Shares to be credited to each participant’s account will be determined by dividing the dollar amount of the distribution or dividend by the higher of NAV or 95% of the market price. If the market price is lower than NAV, or if dividends or distributions are payable only in cash, then participants will receive Common Shares purchased by the Plan Agent on participants’ behalf on the NYSE or otherwise on the open market. If the market price exceeds NAV before the Plan Agent has completed its purchases, the average per share purchase price may exceed NAV, resulting in fewer Common Shares being acquired than if the Fund had issued new Common Shares.

There are no brokerage charges with respect to Common Shares issued directly by the Fund. However, whenever shares are purchased or sold on the NYSE or otherwise on the open market, each participant will pay a pro rata portion of brokerage trading fees, currently $0.05 per share purchased or sold. Brokerage trading fees will be deducted from amounts to be invested.

The reinvestment of dividends and net capital gain distributions does not relieve participants of any income tax that may be payable on such dividends or distributions even though cash is not received by the participant.

Shareholders participating in the Plan may buy additional Common Shares of the Fund through the Plan at any time in amounts of at least $50 per investment, up to a maximum of $10,000, with a total calendar year limit of $100,000. Shareholders will be charged a $5 transaction fee plus $0.05 per share brokerage trading fee for each order. Purchases of additional shares of the Fund will be made on the open market. Shareholders who elect to utilize monthly electronic fund transfers to buy additional shares of the Fund will be charged a $2 transaction fee plus $0.05 per share brokerage trading fee for each automatic purchase. Shareholders also can sell Fund shares held in

the Plan account at any time by contacting the Plan Agent by telephone, in writing or by visiting the Plan Agent’s website at www.computershare.com and clicking “EquityAccess & More.” The Plan Agent will mail a check to you (less applicable brokerage trading fees) on settlement date, which is three business days after your shares have been sold. If you choose to sell your shares through your stockbroker, you will need to request that the Plan Agent electronically transfer your shares to your stockbroker through the Direct Registration System.

Shareholders participating in the Plan may elect to receive all distributions in cash by withdrawing from the Plan at any time by contacting the Plan Agent by telephone, in writing or by visiting the Plan Agent’s website at www.computershare.com and clicking “EquityAccess & More.” Such termination will be effective immediately if the notice is received by the Plan Agent prior to any dividend or distribution record date; otherwise, such termination will be effective on the first trading day after the payment date for such dividend or distribution, with respect to any subsequent dividend or distribution. If you withdraw, your shares will be credited to your account; or, if you wish, the Plan Agent will sell your full and fractional shares and send you the proceeds, less a transaction fee of $5.00 and less brokerage trading fees of $0.05 per share. If a shareholder does not maintain at least one whole share of common stock in the Plan account, the Plan Agent may terminate such shareholder’s participation in the Plan after written notice. Upon termination, shareholders will be sent a check for the cash value of any fractional share in the Plan account, less any applicable broker commissions and taxes.

Shareholders who hold at least one full share of the Fund may join the Plan by notifying the Plan Agent by telephone, in writing or by visiting the Plan Agent’s website at www.computershare.com and clicking “EquityAccess & More.” If received in proper form by the Plan Agent before the record date of a dividend, the election will be effective with respect to all dividends paid after such record date. If you wish to participate in the Plan and your shares are held in the name of a brokerage firm, bank or other nominee, please contact your nominee to see if it will participate in the Plan for you. If you wish to participate in the Plan, but your brokerage firm, bank or other nominee is unable to participate on your behalf, you will need to request that your shares be re-registered in your own name, or you will not be able to participate. The Plan Agent will administer the Plan on the basis of the number of shares certified from time to time by you as representing the total amount registered in your name and held for your account by your nominee.

Experience under the Plan may indicate that changes are desirable. Accordingly, the Fund and the Plan Agent reserve the right to amend or terminate the Plan. Participants generally will receive written notice at least 90 days before the effective date of any amendment. In the case of termination, participants will receive written notice at least 90 days before the record date for the payment of any dividend or distribution by the Fund.

All correspondence or additional information about the Plan should be directed to Computershare, Inc. (Telephone: 800-852-0218 (within the U.S. and Canada), 201-680-6578 (International Telephone Inquiries), and 201-680-6610 (For the Hearing Impaired (TDD)).

Closed-End Fund Structure

Closed-end funds differ from open-end management investment companies (which generally are referred to as “mutual funds”) in that closed-end funds generally list their shares for trading on a securities exchange and do not redeem their shares at the option of the shareholder. Mutual funds do not trade on securities exchanges and issue securities redeemable at the option of the shareholder. The continuous outflows of assets in a mutual fund can make it difficult to manage the Fund’s investments. Closed-end funds generally are able to stay more fully invested in securities that are consistent with their investment objectives and also have greater flexibility to make certain types of investments and to use certain investment strategies, such as financial leverage and investments in illiquid securities. The Fund’s Common Shares are designed primarily for long-term investors; you should not purchase Common Shares if you intend to sell them shortly after purchase.

Common shares of closed-end funds frequently trade at prices lower than their NAV. Since inception, the market price of the Common Shares has fluctuated and at times has traded below the Fund’s NAV and at times has traded above the Fund’s NAV. The Fund cannot predict whether in the future the Common Shares will trade at, above or below NAV. In addition to NAV, the market price of the Fund’s Common Shares may be affected by such factors as the Fund’s dividend stability, dividend levels, which are in turn affected by expenses, and market supply and demand.

In recognition of the possibility that Common Shares may trade at a discount from their NAV, and that any such discount may not be in the best interest of Common Shareholders, the Board, in consultation with the Advisor, from time to time may review possible actions to reduce any such discount. There can be no assurance that the Board will

decide to undertake any of these actions or that, if undertaken, such actions would result in Common Shares trading at a price equal to or close to NAV per Common Share. In the event that the Fund conducts an offering of new Common Shares and such offering constitutes a “distribution” under Regulation M, the Fund and certain of its affiliates may be subject to an applicable restricted period that could limit the timing of any repurchases by the Fund.

U.S. Federal Income Tax Matters

The following discussion of U.S. federal income tax matters is based on the advice of K&L Gates LLP. The Fund has elected to be treated and to qualify each year as a regulated investment company (a “RIC”) under the Code. Accordingly, the Fund intends to satisfy certain requirements relating to sources of its income and diversification of its total assets and to distribute substantially all of its net income and net short-term capital gain (after reduction by net long-term capital loss and any available capital loss carryforwards) in accordance with the timing requirements imposed by the Code, so as to maintain its RIC status and to avoid paying U.S. federal income or excise tax thereon. To the extent it qualifies for treatment as a RIC and satisfies the above-mentioned distribution requirements, the Fund will not be subject to U.S. federal income tax on income paid to its shareholders in the form of dividends or capital gain distributions.

At least annually, the Fund intends to distribute any net capital gain (which is the excess of net long-term capital gain over net short-term capital loss) or, alternatively, to retain all or a portion of the year’s net capital gain and pay U.S. federal income tax on the retained gain. As provided under U.S. federal tax law, Common Shareholders of record as of the end of the Fund’s taxable year will include their attributable share of the retained gain in their income for the year as long-term capital gain (regardless of holding period in Common Shares), and will be entitled to a tax credit or refund for the tax paid on their behalf by the Fund. Common Shareholders of record for the retained capital gain also will be entitled to increase their tax basis in their Common Shares by an amount equal to the deemed distribution less the tax credit. Distributions of the Fund’s net capital gain (“capital gain distributions”), if any, are taxable to Common Shareholders as long-term capital gain, regardless of their holding period in Common Shares. Distributions of the Fund’s net realized short-term capital gain will be taxable as ordinary income.

If, for any calendar year, the Fund’s total distributions exceed the Fund’s current and accumulated earnings and profits, the excess will be treated as a return of capital to each Common Shareholder (up to the amount of the Common Shareholder’s basis in his or her Common Shares) and thereafter as gain from the sale of Common Shares (assuming Common Shares are held as a capital asset). The amount treated as a return of capital reduces the Common Shareholder’s adjusted basis in his or her Common Shares, thereby increasing his or her potential gain or reducing his or her potential loss on the subsequent sale or other disposition of his or her Common Shares. See below for a summary of the current maximum tax rates applicable to long-term capital gain (including capital gain distributions).

For federal income tax purposes, the Fund is generally permitted to carry forward a net capital loss incurred in any taxable year beginning after December 23, 2010, for an unlimited period to offset net capital gains, if any, during its taxable years following the year of the loss. The carryforward of capital losses realized in taxable years beginning prior to December 23, 2010, however, is limited to an eight-year period following the year of realization. Further, capital losses carried forward from taxable years beginning after December 23, 2010 will retain their character as either short-term or long-term capital losses, rather than being considered all short-term as under previous law. The Fund must use losses that do not expire before it uses losses that do expire, and the Fund’s ability to utilize capital losses in a given year or in total may be limited. To the extent subsequent net capital gains are offset by such losses, they would not result in federal income tax liability to the Fund and would not be distributed as such to shareholders.

To qualify as a RIC for income tax purposes, the Fund must derive at least 90% of its annual gross income from dividends, interest, payments with respect to securities loans, gain from the sale or other disposition of stock, securities or foreign currencies, or other income (including, but not limited to, gain from options, futures or forward contracts) derived with respect to its business of investing in stock, securities and currencies, and net income derived from an interest in a qualified publicly traded partnership. A “qualified publicly traded partnership” is a publicly traded partnership that meets certain requirements with respect to the nature of its income. To qualify as a RIC, the Fund must also satisfy certain requirements with respect to the diversification of its assets. The Fund must have, at the close of each quarter of the taxable year, at least 50% of the value of its total assets represented by cash, cash items, U.S. government securities, securities of other regulated investment companies, and other securities that, in respect of any one issuer, do not represent more than 5% of the value of the assets of the Fund nor more than 10% of the voting securities of that issuer. In addition, at those times not more than 25% of the value of the Fund’s assets can be invested in securities (other than U.S. government securities or the securities of other regulated investment

companies) of any one issuer, or of two or more issuers, which the Fund controls and which are engaged in the same or similar trades or businesses or related trades or businesses, or of one or more qualified publicly traded partnerships. If the Fund fails to meet the annual gross income test described above, the Fund will nevertheless be considered to have satisfied the test if (i) (a) such failure is due to reasonable cause and not due to willful neglect and (b) the Fund reports the failure, and (ii) the Fund pays an excise tax equal to the excess non-qualifying income. If the Fund fails to meet the asset diversification test described above with respect to any quarter, the Fund will nevertheless be considered to have satisfied the requirements for such quarter if the Fund cures such failure within 6 months and either (i) such failure is de minimis or (ii) (a) such failure is due to reasonable cause and not due to willful neglect and (b) the Fund reports the failure and pays an excise tax.

As a RIC, the Fund generally will not be subject to federal income tax on its investment company taxable income (as that term is defined in the Code, but without regard to the deduction for dividends paid) and net capital gain (the excess of net long-term capital gain over net short-term capital loss), if any, that it distributes in each taxable year to its shareholders, provided that it distributes at least the sum of 90% of its investment company taxable income and 90% of its net tax-exempt interest income for such taxable year. The Fund intends to distribute to its shareholders, at least annually, substantially all of its investment company taxable income, net tax-exempt income and net capital gain. In order to avoid incurring a nondeductible 4% federal excise tax obligation, the Code requires that the Fund distribute (or be deemed to have distributed) by December 31 of each calendar year an amount at least equal to the sum of (i) 98% of its ordinary income for such year, (ii) 98.2% of its capital gain net income (which is the excess of its realized net long-term capital gain over its realized net short-term capital loss), generally computed on the basis of the one-year period ending on October 31 of such year, after reduction by any available capital loss carryforwards and (iii) 100% of any ordinary income and capital gain net income from the prior year (as previously computed) that were not paid out during such year and on which the Fund paid no U.S. federal income tax.

If the Fund does not qualify as a RIC for any taxable year, the Fund’s taxable income will be subject to corporate income taxes, and all distributions from earnings and profits, including distributions of net capital gain (if any), will be taxable to the shareholder as ordinary income. Such distributions generally would be eligible (i) to be treated as qualified dividend income in the case of individual and other non-corporate shareholders and (ii) for the dividends received deduction (“DRD”) in the case of corporate shareholders. In addition, in order to requalify for taxation as a RIC, the Fund may be required to recognize unrealized gain, pay substantial taxes and interest, and make certain distributions.

Certain of the Fund’s investment practices are subject to special and complex U.S. federal income tax provisions that may, among other things, (i) convert dividends that would otherwise constitute qualified dividend income into ordinary income, (ii) treat dividends that would otherwise be eligible for the corporate DRD as ineligible for such treatment, (iii) disallow, suspend or otherwise limit the allowance of certain loss or deductions, (iv) convert long-term capital gain into short-term capital gain or ordinary income, (v) convert an ordinary loss or deduction into a capital loss (the deductibility of which is more limited), (vi) cause the Fund to recognize income or gain without a corresponding receipt of cash, (vii) adversely affect when a purchase or sale of stock or securities is deemed to occur, (viii) adversely alter the characterization of certain complex financial transactions, and (ix) produce income that will not qualify as good income for purposes of the income requirement that applies to RICs. While it may not always be successful in doing so, the Fund will seek to avoid or minimize the adverse tax consequences of its investment practices.

The Fund may recognize gain (but not loss) from a constructive sale of certain “appreciated financial positions” if the Fund enters into a short sale, offsetting notional principal contract, or forward contract transaction with respect to the appreciated position or substantially identical property. Appreciated financial positions subject to this constructive sale treatment include interests (including options and forward contracts and short sales) in stock and certain other instruments. Constructive sale treatment does not apply if the transaction is closed out not later than thirty days after the end of the taxable year in which the transaction was initiated, and the underlying appreciated securities position is held unhedged for at least the next sixty days after the hedging transaction is closed.

Gain or loss from a short sale of property generally is considered as capital gain or loss to the extent the property used to close the short sale constitutes a capital asset in the Fund’s hands. Except with respect to certain situations where the property used to close a short sale has a long-term holding period on the date the short sale is entered into, gain on short sales generally are short-term capital gain. A loss on a short sale will be treated as a long-term capital loss if, on the date of the short sale, “substantially identical property” has been held by the Fund for more than one

year. In addition, entering into a short sale may result in suspension of the holding period of “substantially identical property” held by the Fund.

Gain or loss on a short sale generally will not be realized until such time as the short sale is closed. However, as described above in the discussion of constructive sales, if the Fund holds a short sale position with respect to securities that have appreciated in value, and it then acquires property that is the same as or substantially identical to the property sold short, the Fund generally will recognize gain on the date it acquires such property as if the short sale were closed on such date with such property. Similarly, if the Fund holds an appreciated financial position with respect to securities and then enters into a short sale with respect to the same or substantially identical property, the Fund generally will recognize gain as if the appreciated financial position were sold at its fair market value on the date it enters into the short sale. The subsequent holding period for any appreciated financial position that is subject to these constructive sale rules will be determined as if such position were acquired on the date of the constructive sale.

The Fund will inform Common Shareholders of the source and tax status of all distributions promptly after the close of each calendar year.

Selling Common Shareholders generally will recognize gain or loss in an amount equal to the difference between the amount realized on the sale and the Common Shareholder’s adjusted tax basis in the Common Shares sold. If Common Shares are held as a capital asset, the gain or loss will be a capital gain or loss. The maximum tax rate applicable to net capital gain recognized by individuals and other non-corporate taxpayers is (i) the same as the maximum ordinary income tax rate for gain recognized on the sale of capital assets held for one year or less (currently 39.6%), or (ii) for gain recognized on the sale of capital assets held for more than one year (as well as any capital gain distributions), 20% for individuals in the 39.6% tax bracket, 15% for individuals in the 25% to 35% tax brackets, or 0% for individuals in the 10% or 15% tax brackets. An additional 3.8% Medicare tax will also apply in the case of some individuals.

Any loss on a disposition of Common Shares held for six months or less will be treated as a long-term capital loss to the extent of any capital gain distributions received with respect to those Common Shares. For purposes of determining whether Common Shares have been held for six months or less, the holding period is suspended for any periods during which the Common Shareholder’s risk of loss is diminished as a result of holding one or more other positions in substantially similar or related property, or through certain options or short sales. Any loss realized on a sale or exchange of Common Shares will be disallowed to the extent those Common Shares are replaced by other Common Shares within a period of 61 days beginning 30 days before and ending 30 days after the date of disposition of Common Shares (whether through the reinvestment of distributions or otherwise). In that event, the basis of the replacement Common Shares will be adjusted to reflect the disallowed loss.

An investor should be aware that, if Common Shares are purchased shortly before the record date for any taxable distribution (including a capital gain distribution), the purchase price likely will reflect the value of the distribution and the investor then would receive a taxable distribution that is likely to reduce the trading value of such Common Shares, in effect resulting in a taxable return of some of the purchase price.

Taxable distributions to certain individuals and certain other non-corporate Common Shareholders, including those who have not provided their correct taxpayer identification number and other required certifications, may be subject to “backup” U.S. federal income tax withholding at the fourth lowest rate of tax applicable to a single individual (28%). Backup withholding is not an additional tax. Any amounts withheld may be refunded or credited against such shareholder’s U.S. federal income tax liability, if any, provided that the required information is furnished to the Internal Revenue Service.

An investor also should be aware that the benefits of the reduced tax rate applicable to long-term capital gain and qualified dividend income may be impacted by the application of the alternative minimum tax to individual shareholders.

The Fund’s investments in non-U.S. securities may be subject to foreign withholding taxes on dividends, interest, or capital gain, which will decrease the Fund’s yield. Foreign withholding taxes may be reduced under income tax treaties between the U.S. and certain foreign jurisdictions.

Depending on the number of non-U.S. shareholders in the Fund, however, such reduced foreign withholding tax rates may not be available for investments in certain jurisdictions.

The foregoing briefly summarizes some of the important U.S. federal income tax consequences to Common Shareholders of investing in Common Shares, reflects the U.S. federal tax law as of the date of this Prospectus, and does not address special tax rules applicable to certain types of investors, such as corporate and non-U.S. investors. A more complete discussion of the tax rules applicable to the Fund and the Common Shareholders can be found in the SAI that is incorporated by reference into this Prospectus. Unless otherwise noted, this discussion assumes that an investor is a U.S. person and holds Common Shares as a capital asset. This discussion is based upon current provisions of the Code, the regulations promulgated thereunder, and judicial and administrative ruling authorities, all of which are subject to change or differing interpretations by the courts or the IRS retroactively or prospectively. Investors should consult their tax advisors regarding other U.S. federal, state or local tax considerations that may be applicable in their particular circumstances, as well as any proposed tax law changes.

Plan of Distribution

The Fund may sell the Common Shares being offered under this Prospectus in any one or more of the following ways: (i) directly to purchasers; (ii) through agents; (iii) to or through underwriters; or (iv) through dealers. The Prospectus Supplement relating to the offering will identify any agents, underwriters or dealers involved in the offer or sale of Common Shares, and will set forth any applicable offering price, sales load, fee, commission or discount arrangement between the Fund and its agents or underwriters, or among its underwriters, or the basis upon which such amount may be calculated, net proceeds and use of proceeds, and the terms of any sale.

The Fund may distribute Common Shares from time to time in one or more transactions at: (i) a fixed price or prices, which may be changed; (ii) market prices prevailing at the time of sale; (iii) prices related to prevailing market prices; or (iv) negotiated prices; provided, however, that in each case the offering price per Common Share (less any underwriting commission or discount) must equal or exceed the NAV per Common Share.

The Fund from time to time may offer its Common Shares through or to certain broker-dealers, including UBS Securities LLC, that have entered into selected dealer agreements relating to at-the-market offerings.

The Fund may directly solicit offers to purchase Common Shares, or the Fund may designate agents to solicit such offers. The Fund will, in a Prospectus Supplement relating to such offering, name any agent that could be viewed as an underwriter under the Securities Act of 1933, as amended (the “Securities Act”), and describe any commissions the Fund must pay. Any such agent will be acting on a best efforts basis for the period of its appointment or, if indicated in the applicable Prospectus Supplement or other offering materials, on a firm commitment basis. Agents, dealers and underwriters may be customers of, engage in transactions with, or perform services for the Fund in the ordinary course of business.

If any underwriters or agents are used in the sale of Common Shares in respect of which this Prospectus is delivered, the Fund will enter into an underwriting agreement or other agreement with them at the time of sale to them, and the Fund will set forth in the Prospectus Supplement relating to such offering their names and the terms of the Fund’s agreement with them.

If a dealer is utilized in the sale of Common Shares in respect of which this Prospectus is delivered, the Fund will sell such Common Shares to the dealer, as principal. The dealer may then resell such Common Shares to the public at varying prices to be determined by such dealer at the time of resale.

The Fund may engage in at-the-market offerings to or through a market maker or into an existing trading market, on an exchange or otherwise, in accordance with Rule 415(a)(4) under the Securities Act. An at-the-market offering may be through an underwriter or underwriters acting as principal or agent for the Fund.

Agents, underwriters and dealers may be entitled under agreements which they may enter into with the Fund to indemnification by the Fund against certain civil liabilities, including liabilities under the Securities Act, and may be customers of, engage in transactions with or perform services for the Fund in the ordinary course of business.

In order to facilitate the offering of Common Shares, any underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of Common Shares or any other Common Shares the prices of which may be used to determine payments on the Common Shares. Specifically, any underwriters may over-allot in connection with the offering, creating a short position for their own accounts. In addition, to cover over-allotments or to stabilize the price of Common Shares or of any such other Common Shares, the underwriters may bid for, and purchase, Common Shares or any such other Common Shares in the open market. Finally, in any offering of Common Shares through a syndicate of underwriters, the underwriting syndicate may reclaim selling concessions allowed to an underwriter or a dealer for distributing Common Shares in the offering if the syndicate repurchases previously distributed Common Shares in transactions to cover syndicate short positions, in stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market price of Common Shares above independent market levels. Any such underwriters are not required to engage in these activities and may end any of these activities at any time.

The Fund may enter into derivative transactions with third parties, or sell Common Shares not covered by this Prospectus to third parties in privately negotiated transactions. If the applicable Prospectus Supplement indicates, in connection with those derivatives, the third parties may sell Common Shares covered by this Prospectus and the applicable Prospectus Supplement or other offering materials, including in short sale transactions. If so, the third parties may use Common Shares pledged by the Fund or borrowed from the Fund or others to settle those sales or to close out any related open borrowings of securities, and may use Common Shares received from the Fund in settlement of those derivatives to close out any related open borrowings of securities. The third parties in such sale transactions will be underwriters and, if not identified in this Prospectus, will be identified in the applicable Prospectus Supplement or other offering materials (or a post-effective amendment).

The Fund or one of the Fund’s affiliates may loan or pledge Common Shares to a financial institution or other third party that in turn may sell Common Shares using this Prospectus. Such financial institution or third party may transfer its short position to investors in Common Shares or in connection with a simultaneous offering of other Common Shares offered by this Prospectus or otherwise.

The maximum amount of compensation to be received by any member of the Financial Industry Regulatory Authority, Inc. will not exceed 8% of the initial gross proceeds from the sale of any security being sold with respect to each particular offering of Common Shares made under a single Prospectus Supplement.

Any underwriter, agent or dealer utilized in the initial offering of Common Shares will not confirm sales to accounts over which it exercises discretionary authority without the prior specific written approval of its customer.

Description of Capital Structure

The Fund is a business trust established under the laws of The Commonwealth of Massachusetts by the Declaration of Trust. The Declaration of Trust provides that the Board may authorize separate classes of shares of beneficial interest. The Board has authorized an unlimited number of Common Shares. The Fund holds annual meetings of Common Shareholders in compliance with the requirements of the NYSE.

COMMON SHARES

The Declaration of Trust permits the Fund to issue an unlimited number of full and fractional Common Shares of beneficial interest, with or without par value. Each Common Share represents an equal proportionate interest in the assets of the Fund with each other Common Share in the Fund. Common Shareholders will be entitled to the payment of distributions when, and if declared by the Fund. The 1940 Act or the terms of any future borrowings or issuance of preferred shares may limit the payment of distributions to the Common Shareholders. Each whole Common Share is entitled to one vote and each fractional Common Share is entitled to a proportionate fractional vote as to matters on which it is entitled to vote pursuant to the terms of the Declaration of Trust. Upon termination of the Fund, after paying or adequately providing for the payment of all liabilities of the Fund and the liquidation preference with respect to any outstanding preferred shares, and upon receipt of such releases, indemnities and refunding agreements as the Trustees deem necessary, the Trustees may distribute the remaining assets of the Fund among the Common Shareholders. The Declaration of Trust provides that Common Shareholders are not liable for any liabilities of the Fund, and indemnifies shareholders against any such liability. Although shareholders of a business trust established under Massachusetts law, in certain limited circumstances, may be held personally liable

for the obligations of the business trust as though they were general partners, the provisions of the Declaration of Trust described in the foregoing sentence make the likelihood of such personal liability remote. The Fund will not issue Common Share certificates.

The Fund has no current intention to issue preferred shares. However, if at some future time there are any preferred shares outstanding, subject to certain exceptions, the Fund might not be permitted to declare any cash distribution on its Common Shares, unless at the time of such declaration, (i) all accrued distributions on preferred shares and any accrued interest on borrowings, if any, have been paid and (ii) the value of the Fund’s total assets (determined after deducting the amount of such distribution), less all liabilities and indebtedness of the Fund not represented by senior securities, is at least 300% of the aggregate amount of any securities representing indebtedness and at least 200% of the aggregate amount of any securities representing indebtedness plus the aggregate liquidation value of the outstanding preferred shares. In addition to the requirements of the 1940 Act, the Fund may be required to comply with other asset coverage requirements under a liquidity facility or as a condition of the Fund obtaining a rating of preferred shares from a nationally recognized statistical rating organization (a “Rating Agency”). These requirements may include an asset coverage test more stringent than under the 1940 Act. This limitation on the Fund’s ability to make distributions on its Common Shares could in certain circumstances impair the ability of the Fund to maintain its qualification for taxation as a RIC for U.S. federal income tax purposes. If the Fund were in the future to issue preferred shares, it would intend, however, to the extent possible, to purchase or redeem preferred shares from time to time to maintain compliance with such asset coverage requirements and may pay special distributions to the holders of the preferred shares in certain circumstances in connection with any potential impairment of the Fund’s status as a RIC. Depending on the timing of any such redemption or repayment, the Fund may be required to pay a premium in addition to the liquidation preference of the preferred shares to the holders thereof.

The Fund has no present intention of offering additional Common Shares, except as described herein. Other offerings of its Common Shares, if made, will require approval of the Board. Any additional offering will not be sold at a price per Common Share below the then current NAV (exclusive of underwriting discounts and commissions) except in connection with an offering to existing Common Shareholders or with the consent of a majority of the Fund’s outstanding Common Shares. Common Shares have no preemptive rights.

LIQUIDITY FACILITY

The Fund has entered into the LA with State Street Bank and Trust Company ("SSB") that allows it to borrow or otherwise access funds through a line of credit, securities lending and reverse repurchase agreements. The Fund pledges its assets as collateral to secure obligations under the LA. The Fund retains the risks and rewards of the ownership of assets pledged to secure obligations under the LA and makes these assets available for securities lending and reverse repurchase transactions with SSB acting as the Fund's authorized agent for these transactions. All transactions initiated through SSB are required to be secured with cash collateral received from the securities borrower or cash is received from the reverse repurchase agreement counterparties. Securities lending transactions (other than reverse repurchase) will be secured with cash collateral in amounts at least equal to 100% of the market value of the securities utilized in these transactions. Cash received by SSB from securities lending or reverse repurchase transactions is credited against the amounts borrowed under the line of credit.

Upon return of securities by the borrower or reverse repurchase counterparty, SSB will return the cash collateral to the borrower or proceeds from the reverse repurchase transaction, as applicable, which will eliminate the credit against the line of credit and will cause the drawdowns under the line of credit to increase by the amounts returned. Income earned on the loaned securities is retained by SSB, and any interest due on the reverse repurchase agreements is paid by SSB.

SSB has indemnified the fund for certain losses that may arise if the borrower or a reverse repurchase counterparty fails to return securities when due. With respect to securities lending transactions, upon a default of the securities borrower, SSB uses the collateral received from the borrower to purchase replacement securities of the same issue, type, class and series. If the value of the collateral is less than the purchase cost of replacement securities, SSB is responsible for satisfying the shortfall, but only to the extent that the shortfall is not due to any of the fund's losses on the reinvested cash collateral. Although the risk of the loss of the securities is mitigated by receiving collateral from the borrower or proceeds from the reverse repurchase counterparty and through SSB indemnification, the fund could experience a delay in recovering securities or could experience a lower than expected return if the borrower or reverse repurchase counterparty fails to return the securities on a timely basis.

Under normal circumstances, interest charged is at the rate of one month LIBOR (London Interbank Offered Rate) plus 0.60% effective December 2, 2015, and at the rate of one month LIBOR plus 0.70% prior to December 2, 2015, and is payable monthly on the aggregate balance of the drawdowns outstanding under the LA. As of October 31, 2015, the Fund had an average daily loan balance of $86,900,000 at an average interest rate of 0.86%.

After the six month anniversary of the effective date of the agreement, the Fund may terminate the LA with 60 days' notice. If certain asset coverage and collateral requirements, or other covenants are not met, the LA could be deemed in default and result in termination. Absent a default or facility termination event, SSB is required to provide the Fund with 360 days' notice prior to terminating the LA.

By leveraging its investment portfolio, the Fund creates an opportunity for increased net income or capital appreciation. However, the use of leverage also involves risks, which can be significant. See "Liquidity Risk."

REPURCHASE OF SHARES AND OTHER DISCOUNT MEASURES

In recognition of the possibility that Common Shares might trade at a discount to NAV and that any such discount may not be in the interest of the Fund’s shareholders, the Board, in consultation with the Advisor, from time to time may review possible actions to help reduce any such discount. The Board, in consultation with the Advisor, may review the possibility of open market repurchases and/or tender offers for the Common Shares and consider such factors as the market price of the Common Shares, the NAV of the Common Shares, the liquidity of the assets of the Fund, effect on the Fund’s expenses, whether such transactions would impair the Fund’s status as a RIC or result in a failure to comply with applicable asset coverage requirements, general economic conditions and such other events or conditions, which may have a material effect on the Fund’s ability to consummate such transactions. There are no assurances that the Board will, in fact, decide to undertake either of these actions or, if undertaken, that such actions will result in the Fund’s Common Shares trading at a price which is equal to or approximates their NAV.

In the event that the Fund conducts an offering of new Common Shares and such offering constitutes a “distribution” under Regulation M, the Fund and certain of its affiliates may be subject to an applicable restricted period that could limit the timing of any repurchases by the Fund.

PREFERRED SHARES

The Declaration of Trust authorizes the issuance of an unlimited number of shares of beneficial interest with preference rights, including preferred shares (“Preferred Shares”), having no par value per share or such other amount as the Board may establish, in one or more series, with rights as determined by the Board, by action of the Board without the approval of the Common Shareholders. The Board has no current intention to issue Preferred Shares.

Under the requirements of the 1940 Act, the Fund must, immediately after the issuance of any Preferred Shares, have an “asset coverage” of at least 200%. Asset coverage means the ratio which the value of the total assets of the Fund, less all liability and indebtedness not represented by senior securities (as defined in the 1940 Act), bears to the aggregate amount of senior securities representing indebtedness of the Fund, if any, plus the aggregate liquidation preference of the Preferred Shares. If the Fund seeks a rating of the Preferred Shares, asset coverage requirements, in addition to those set forth in the 1940 Act, may be imposed. The liquidation value of the Preferred Shares is expected to equal their aggregate original purchase price plus redemption premium, if any, together with any accrued and unpaid dividends thereon (on a cumulative basis), whether or not earned or declared. The terms of the Preferred Shares, including their dividend rate, voting rights, liquidation preference and redemption provisions, will be determined by the Board (subject to applicable law and the Declaration of Trust) if and when it authorizes the Preferred Shares. The Fund may issue Preferred Shares that provide for the periodic redetermination of the dividend rate at relatively short intervals through an auction or remarketing procedure, although the terms of the Preferred Shares also may enable the Fund to lengthen such intervals. At times, the dividend rate as redetermined on the Fund’s Preferred Shares may approach or exceed the Fund’s return after expenses on the investment of proceeds from the Preferred Shares and the Fund’s leveraged capital structure would result in a lower rate of return to Common Shareholders than if the Fund were not so structured.

In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Fund, the terms of any Preferred Shares may entitle the holders of Preferred Shares to receive a preferential liquidating distribution (expected to equal the original purchase price per share plus redemption premium, if any, together with accrued and

unpaid dividends, whether or not earned or declared and on a cumulative basis) before any distribution of assets is made to Common Shareholders. After payment of the full amount of the liquidating distribution to which they are entitled, the holders of Preferred Shares would not be entitled to any further participation in any distribution of assets by the Fund.

Under the 1940 Act, if at any time dividends on the Preferred Shares are unpaid in an amount equal to two full years’ dividends thereon, the holders of all outstanding Preferred Shares, voting as a class, will be allowed to elect a majority of the Fund’s Trustees until all dividends in default have been paid or declared and set apart for payment. In addition, if required by the Rating Agency rating the Preferred Shares or if the Board determines it to be in the best interests of the Common Shareholders, issuance of the Preferred Shares may result in more restrictive provisions than required by the 1940 Act being imposed. In this regard, holders of the Preferred Shares may be entitled to elect a majority of the Board in other circumstances, for example, if one payment on the Preferred Shares is in arrears.

If the Fund were to issue Preferred Shares, it is expected that the Fund would seek a credit rating for the Preferred Shares from a Rating Agency. In that case, as long as Preferred Shares are outstanding, the composition of its portfolio would reflect guidelines established by such Rating Agency. Although, as of the date hereof, no such Rating Agency has established guidelines relating to any such Preferred Shares, based on previous guidelines established by such Rating Agencies for the securities of other issuers, the Fund anticipates that the guidelines with respect to the Preferred Shares would establish a set of tests for portfolio composition and asset coverage that supplement (and in some cases are more restrictive than) the applicable requirements under the 1940 Act. Although, at this time, no assurance can be given as to the nature or extent of the guidelines, which may be imposed in connection with obtaining a rating of the Preferred Shares, the Fund currently anticipates that such guidelines will include asset coverage requirements, which are more restrictive than those under the 1940 Act, restrictions on certain portfolio investments and investment practices, requirements that the Fund maintain a portion of its total assets in short-term, high-quality, fixed-income securities and certain mandatory redemption requirements relating to the Preferred Shares. No assurance can be given that the guidelines actually imposed with respect to the Preferred Shares by such Rating Agency will be more or less restrictive than as described in this Prospectus.

Certain Provisions in the Declaration of Trust and By-Laws

Under Massachusetts law, shareholders, in certain circumstances, could be held personally liable for the obligations of the Fund. However, the Declaration of Trust contains an express disclaimer of shareholder liability in connection with Fund property or the acts, obligations or affairs of the Fund and provides for indemnification out of the assets of the Fund for all loss and expense of any shareholder held personally liable for the obligations of the Fund. Thus, the risk of a shareholder incurring financial loss on account of shareholder liability is limited to circumstances in which the Fund would be unable to meet its obligations. The Fund believes that the likelihood of such circumstances is remote.

The Declaration of Trust provides that the Trustees may amend the Declaration of Trust without Common Shareholder approval to change the name of the Fund or to supply any omission, clear any ambiguity or correct or supplement a defective or inconsistent provision. The Declaration of Trust does not permit amendments that impair the exemption from personal liability of the shareholders, Trustees, officers, employees and agents of the Fund or permit assessments upon shareholders.

The By-laws provide that the Trustees have the power, to the exclusion of shareholders, to adopt, alter, amend or repeal any of the By-laws, except for any By-law that requires a vote of the shareholders to be amended, adopted or repealed by the terms of the Declaration of Trust, By-laws or applicable law.

ANTI-TAKEOVER PROVISIONS

The Declaration of Trust and By-laws include provisions that could have the effect of limiting the ability of other entities or persons to acquire control of the Fund or to change the composition of its Board and could have the effect of depriving Common Shareholders of an opportunity to sell their Common Shares at a premium over prevailing market prices by discouraging a third party from seeking to obtain control of the Fund. These provisions may have the effect of discouraging attempts to acquire control of the Fund, which attempts could have the effect of increasing the expenses of the Fund and interfering with the normal operation of the Fund. They provide, however, the advantage of potentially requiring persons seeking control of the Fund to negotiate with its management regarding

the price to be paid and facilitating the continuity of the Fund’s investment objectives and policies. The Board has considered and approved the following anti-takeover provisions . The following is only a summary and is qualified in its entirety by reference to the Declaration of Trust and By-laws on file with the SEC.

The number of Trustees is currently thirteen, but by action of a majority of the Trustees, the Board may from time to time be increased or decreased. If the Fund issues Preferred Shares, the Fund may establish a separate class for the Trustees elected by the holders of the Preferred Shares. Subject to applicable provisions of the 1940 Act, vacancies on the Board may be filled by a majority action of the remaining Trustees. Such provisions may work to delay a change in the majority of the Board.

Generally, the shareholders have power to vote only: (a) for the election of Trustees; (b) with respect to any investment advisory or management contract; (c) with respect to a termination of the Fund; (d) with respect to an amendment of the Declaration of Trust; (e) with respect to a merger, consolidation or sale of assets of the Fund; (f) with respect to incorporation of the Fund; (g) to the same extent as the stockholders of a Massachusetts business corporation as to whether or not a court action, proceeding or claim should or should not be brought or maintained derivatively or as a class action on behalf of the Fund or the shareholders; and (h) with respect to such additional matters relating to the Fund as may be required by the Declaration of Trust or the By-Laws or by reason of the registration of the Fund or the shares with the SEC or any state or by any applicable law or any regulation or order of the SEC or any state or as the Trustees may consider necessary or desirable. On any matter required or permitted to be voted on by the shareholders, all shares then entitled to vote shall be voted in the aggregate as a single class without regard to class, except (i) when required by the Declaration of Trust, the By-Laws, the 1940 Act, or when the Trustees have determined that any matter to be submitted to a vote of the shareholders affects the rights or interests of the shareholders of one or more classes, if any, materially differently, shares shall be voted by each such affected class individually; and (ii) when the Trustees shall have determined that the matter affects only the interests of one or more classes, then only the shareholders of such affected class shall be entitled to vote thereon.

Additionally, the Fund’s By-laws contain certain provisions that may tend to make a change of control of the Fund more difficult. For example, the By-laws (i) require a shareholder to give written advance notice and other information to the Fund of the shareholder’s nominees for Trustees and proposals for other business to be considered at annual shareholders’ meetings, or in the event a shareholder proposes to seek a shareholder action by written consent or requests a special meeting of shareholders; (ii) require any such notice by a shareholder to be accompanied by certain information as provided in the By-laws; (iii) provide that Trustees may be nominated by shareholders only at an annual meeting of the Fund or special meeting in lieu of an annual meeting; and (iv) reserve to the Trustees the exclusive power to alter, amend or repeal any provision of the By-laws or to make new By-laws, except where the Declaration of Trust, By-laws or applicable law would also require a shareholder vote to effect such alteration, amendment or repeal. The foregoing description of the By-laws is qualified in its entirety by the full text of the Amended and Restated By-laws effective as of September 27, 2013.

POTENTIAL CONVERSION TO OPEN-END FUND

Conversion of the Fund to an open-end management investment company would require an amendment to the Fund’s Declaration of Trust. Such amendment would require approval by each of the following: (i) a majority of the Trustees then in office, (ii) a majority of the outstanding voting securities, and (iii) by such vote or votes of the holders of any class or classes or series of shares as may be required by the 1940 Act. In the event of conversion, the Common Shares would cease to be listed on the NYSE or other national securities exchange or market system. The Board believes, however, that the closed-end structure is desirable, given the Fund’s investment objective and policies. Investors should assume, therefore, that it is unlikely that the Board would vote to convert the Fund to an open-end management investment company. Shareholders of an open-end management investment company may require the company to redeem their shares at any time (except in certain circumstances as authorized by or under the 1940 Act) at their NAV, less such redemption charge, if any, as might be in effect at the time of a redemption. The Fund would expect to pay all such redemption requests in cash, but intends to reserve the right to pay redemption requests in a combination of cash or securities. If such partial payment in securities were made, investors may incur brokerage costs in converting such securities to cash. If the Fund were converted to an open-end fund, it is likely that new Common Shares would be sold at NAV plus a sales load.
