$175,000,000

Western Asset High Income Fund II Inc.

Common Stock

Subscription Rights to Purchase Common Stock

The Fund. Western Asset High Income Fund II Inc., a Maryland corporation (the “Fund”), is a diversified, closed-end management investment company.

Investment Objectives. The Fund’s primary investment objective is to maximize current income. As a secondary objective, the Fund seeks capital appreciation to the extent consistent with its objective of seeking to maximize current income. There can be no assurance that the Fund will achieve its investment objectives.

Investment Strategies. Under normal conditions, the Fund will invest at least 80% of its net assets plus any borrowings for investment purposes in high-yield debt securities. High yield securities are medium or lower rated securities and unrated securities of comparable quality, sometimes referred to as “high yield” or “junk” bonds. See “Risks—Below Investment Grade Securities (High-Yield) Risk.” Certain of the debt securities purchased by the Fund may be rated as low as “C” by Moody’s Investor Service (“Moody’s”) or “D” by Standard & Poor’s Ratings Services (“S&P”) or may be comparable to securities so rated. The Fund is not required to dispose of a debt security if its credit rating or credit quality declines. The Fund invests up to 35% of its total assets in debt securities of issuers located in emerging market countries. See “Risks—Emerging Markets Risk.”

The Fund’s shares of common stock, par value $0.001 per share (“Common Stock”), are listed on the New York Stock Exchange (“NYSE”) under the trading or “ticker” symbol “HIX.” The net asset value of our Common Stock at the close of business on February 28, 2022 was $6.39 per share, and the last sale price per share of our Common Stock on the NYSE on that date was $6.37.

Offering. The Fund may offer, from time to time, in one or more offerings, shares of our Common Stock, which we also refer to as our securities, at prices and on terms to be set forth in one or more Prospectus Supplements to this Prospectus.

We may offer and sell our securities to or through underwriters, through dealers or agents that we designate from time to time, directly to purchasers, through at-the-market offerings or through a combination of these methods. If an offering of securities involves any underwriters, dealers or agents, then the applicable Prospectus Supplement will name the underwriters, dealers or agents and will provide information regarding any applicable purchase price, fee, commission or discount arrangements made with those underwriters, dealers or agents or the basis upon which such amount may be calculated. See “Plan of Distribution.” We may not sell any of our securities through agents, underwriters or dealers without delivery of a Prospectus Supplement describing the method and terms of the offering of our securities.

Investment Manager and Subadviser. Legg Mason Partners Fund Advisor, LLC (“LMPFA” or the “Manager”), the Fund’s investment manager, supervises the day-to-day management of the Fund’s portfolio by Western Asset Management Company, LLC (“Western Asset”), Western Asset Management Company Limited (“Western Asset Limited”) and Western Asset Management Company Pte. Ltd. (“Western Asset Singapore”) and provides administrative and management services to the Fund.

Investing in the Fund’s securities involves certain risks. You could lose some or all of your investment. See “Risks” beginning on page 32 of this Prospectus and any Prospectus Supplement.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this Prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

Prospectus dated                , 2022.

Western Asset, the Fund’s subadviser, is responsible for the day-to-day portfolio management of the Fund, subject to the supervision of the Fund’s Board of Directors and the Manager. As of December 31, 2021, Western Asset’s and its supervised affiliates’ total assets under management were approximately $487.4 billion.

In connection with Western Asset’s service to the Fund, Western Asset Limited and Western Asset Singapore provide certain subadvisory services to the Fund relating to currency transactions and investments in non-U.S. dollar denominated debt securities. The Manager, Western Asset, Western Asset Limited and Western Asset Singapore are wholly-owned subsidiaries of Franklin Resources, Inc., a global investment management organization operating as Franklin Templeton.

Leverage. The Fund may seek to enhance the level of its current distributions to holders of Common Stock (“Common Stockholders”) through the use of leverage. The Fund may use leverage directly at the fund level through borrowings, including loans from certain financial institutions, the use of reverse repurchase agreements and/or the issuance of debt securities (collectively, “Borrowings”), and through the issuance of preferred stock (“Preferred Stock”). The Fund may use leverage through Borrowings in an aggregate amount of up to approximately 33 ¹/₃% of the Fund’s total assets less all liabilities and indebtedness not represented by senior securities (for these purposes, “total net assets”) immediately after such Borrowings. Furthermore, the Fund may use leverage through the issuance of Preferred Stock in an aggregate amount of liquidation preference attributable to the Preferred Stock combined with the aggregate amount of any Borrowings of up to approximately 50% of the Fund’s total net assets immediately after such issuance. The Fund currently expects to use leverage through the issuance of Preferred Stock. In addition, the Fund may enter into additional reverse repurchase agreements and/or use similar investment management techniques that may provide leverage, but which are not subject to the foregoing 33 ¹/₃% limitation so long as the Fund has covered its commitment with respect to such techniques by segregating liquid assets, entering into offsetting transactions or owning positions covering related obligations. As of February 28, 2022, the total amount of the Fund’s leverage was approximately $154,500,000 (approximately 29% of its portfolio). See “Leverage,” “Description of Shares—Preferred Stock” and “Risks—Risks Related to the Fund—Leverage Risk.”

This Prospectus is part of a registration statement that we have filed with the Securities and Exchange Commission (the “SEC”), using the “shelf” registration process. Under the shelf registration process, we may offer, from time to time, separately or together in one or more offerings, the securities described in this Prospectus. The securities may be offered at prices and on terms described in one or more supplements to this Prospectus. This Prospectus provides you with a general description of the securities that we may offer. Each time we use this Prospectus to offer securities, we will provide a Prospectus Supplement that will contain specific information about the terms of that offering. The Prospectus Supplement may also add, update or change information contained in this Prospectus. This Prospectus, together with any Prospectus Supplement, sets forth concisely the information about us that a prospective investor ought to know before investing. You should read this Prospectus and the related Prospectus Supplement before deciding whether to invest and retain them for future reference. A Statement of Additional Information, dated                , 2022 (the “SAI”), containing additional information about us, has been filed with the SEC and is incorporated by reference in its entirety into this Prospectus. You may request a free copy of the SAI (the table of contents of which is on page 65 of this Prospectus), annual and semi-annual reports to stockholders (when available), and additional information about the Fund by calling (888) 777-0102, by writing to the Fund at 620 Eighth Avenue, 47th Floor, New York, NY 10018 or visiting the Fund’s website (http://www.franklintempleton.com/investments/options/closed-end-funds). The information contained in, or accessed through, the Fund’s website is not part of this Prospectus. You may also obtain a copy of the SAI (and other information regarding the Fund) from the SEC’s Public Reference Room in Washington, D.C. Information relating to the Public Reference Room may be obtained by calling the SEC at (202) 551-8090.

You may also e-mail requests for these documents to publicinfo@sec.gov or make a request in writing to the SEC’s Public Reference Room, 100 F Street, N.E., Washington, D.C. 20549-0102.

As permitted by regulations adopted by the SEC, the Fund does not intend to mail paper copies of the Fund’s shareholder reports, unless you specifically request paper copies of the reports from the Fund or from your financial intermediary (such as a broker-dealer or bank). Instead, the reports will be made available on a website, and you will be notified by mail each time a report is posted and provided with a website link to access the report.

If you have not already elected e-delivery, you may elect to receive shareholder reports and other communications from the Fund electronically by contacting your financial intermediary. You may elect to receive all reports in paper free of charge.

That election will apply to all legacy Legg Mason funds held in your account held directly with the fund complex.

Shares of common stock of closed-end investment companies frequently trade at discounts to their net asset values. If our Common Stock trades at a discount to our net asset value, the risk of loss may increase for purchasers of our Common Stock, especially for those investors who expect to sell their common stock in a relatively short period after purchasing shares in this offering. See “Risks—Market Discount from Net Asset Value Risk.”

THE FUND

The Fund is a diversified, closed-end management investment company registered under the 1940 Act. The Fund was incorporated as a Maryland corporation on March 19, 1998, pursuant to the Charter. The Fund’s principal executive office is located at 620 Eighth Avenue, 47th Floor, New York, New York 10018, and its telephone number is (888) 777-0102.

USE OF PROCEEDS

Unless otherwise specified in a Prospectus Supplement, the Fund intends to invest the net proceeds of any offering of its securities in accordance with its investment objective and policies as stated herein. It is currently anticipated that the Fund will be able to invest substantially all of the net proceeds in accordance with its investment objective and policies within three months after the completion of any offering. Pending such investment, it is anticipated that the proceeds will be primarily invested in short-term money market instruments. The Fund may also invest in U.S. government securities.

MARKET AND NET ASSET VALUE INFORMATION

The Fund’s currently outstanding Common Stock is listed on the NYSE under the symbol “HIX.” Our Common Stock commenced trading on the NYSE on May 21, 1998.

Our Common Stock has traded both at a premium and at a discount in relation to the Fund’s net asset value per share. Although our Common Stock has traded at a premium to net asset value, we cannot assure that this will occur after any offering or that the Common Stock will not trade at a discount in the future. Our issuance of additional Common Stock may have an adverse effect on prices in the secondary market for our Common Stock by increasing the number of shares of Common Stock available, which may create downward pressure on the market price for our Common Stock. Shares of closed-end investment companies frequently trade at a discount to net asset value. See “Risks—Market Discount from Net Asset Value Risk.”

The following table sets forth for each of the periods indicated the range of high and low closing sale price of our Common Stock and the quarter-end sale price, each as reported on the NYSE, the net asset value per share of Common Stock and the premium or discount to net asset value per share at which our shares were trading. Net asset value is generally determined on each business day that the NYSE is open for business. See “Net Asset Value” for information as to the determination of our net asset value.

Source of market prices: Bloomberg.

On February 28, 2022, the last reported sale price of our Common Stock on the NYSE was $6.37, which represented a discount of approximately 0.3% to the net asset value per share reported by us on that date.

As of February 28, 2022, we had approximately 58.9 million shares of Common Stock outstanding and we had net assets applicable to Common Stockholders of approximately $376.1 million.

THE FUND’S INVESTMENTS

Investment Objectives

The Fund’s primary investment objective is to maximize current income. As a secondary objective, the Fund seeks capital appreciation to the extent consistent with its objective of seeking to maximize current income. There can be no assurance the Fund will achieve its investment objectives.

This section provides additional information about the Fund’s investments and certain portfolio management techniques the Fund may use. More information about the Fund’s investments and portfolio management techniques and the associated risks is included in the SAI.

Investment Strategies

Under normal conditions, the Fund will invest at least 80% of its net assets plus any borrowings for investment purposes in high-yield debt securities. Western Asset is free to invest in debt securities of any maturity. Certain of the debt securities purchased by the Fund may be rated as low as “C” by Moody’s Investor Service (“Moody’s”) or “D” by Standard & Poor’s Ratings Services (“S&P”) or may be comparable to securities so rated. The Fund is not required to dispose of a debt security if its credit rating or credit quality declines. The Fund also holds debt securities in the hotels, restaurants and leisure sector as well as in the oil, gas and consumable fuel sector.

The Fund invests up to 35% of its total assets in debt securities of issuers located in emerging market countries. “Emerging market country” is defined to include any country which is, at the time of investment, (i) represented in the J.P. Morgan Emerging Market Bond Index Global or the J.P. Morgan Corporate Emerging Market Bond Index Broad or (ii) categorized by the World Bank in its annual categorization as middle- or low-income. The Fund may also invest in securities denominated in currencies of emerging market countries. There is no minimum rating criteria for the Fund’s investments in such securities. The Fund’s investments in debt securities of emerging market issuers may include dollar and non-dollar-denominated (a) debt obligations issued or guaranteed by foreign national, provincial, state, municipal or other governments with taxing authority or by their agencies or instrumentalities, including Brady bonds; (b) debt obligations of supranational entities; (c) debt obligations and other fixed-income securities of foreign corporate issuers; (d) debt obligations of U.S. corporate issuers; and (e) debt securities issued by corporations that generate significant profits from emerging market countries. The Fund may invest in securities with any market capitalization.

The Fund may invest up to 30% of its assets in zero coupon securities, pay-in-kind bonds and deferred payment securities. The Fund may also invest up to 20% of its total assets in common stock, convertible securities (including contingent convertible securities), warrants, preferred stock or other equity securities of U.S. and foreign issuers when consistent with its objectives.

The Fund may invest in high-yield foreign and U.S. corporate securities including bonds, debentures, notes, commercial paper and preferred stock and will generally be unsecured. The Fund may invest in corporate debt securities with variable rates of interest or which involve equity features, such as contingent interest or participations based on revenues, sales or profits (i.e., interest or other payments, often in addition to a fixed rate of return, that are based on the borrower’s attainment of specified levels of revenues, sales or profits and thus enable the holder of the security to share in the potential success of the venture). The Fund may invest in high-yield debt securities with floating interest rates.

The Fund may invest in Brady bonds, which are debt securities issued under the framework of the Brady Plan as a means for debtor nations to restructure their outstanding external indebtedness; participations in loans between emerging market governments and financial institutions; or fixed-income securities issued by supranational entities such as the World Bank or the European Economic Community.

The Fund may invest in fixed and floating rate loans arranged through private negotiations between a corporate borrower or a foreign sovereign entity and one or more financial institutions in the form of participations in loans and assignments of all or a portion of loans from third parties.

25

In times of adverse market conditions, the Fund may employ alternative strategies, including investment of a substantial portion of the Fund’s assets in securities rated higher than “Baa” by Moody’s or “BBB” by S&P, or in unrated securities of comparable quality. In addition, in order to maintain liquidity, the Fund may invest up to 35% of its total assets in high-quality short-term money market instruments. Such instruments may include obligations of the U.S. Government or its agencies or instrumentalities; commercial paper of issuers rated, at the time of purchase, A-2 or better by S&P or P-2 or better by Moody’s or which, in the opinion of management, are of comparable creditworthiness; certificates of deposit, banker’s acceptances or time deposits of United States banks with total assets of at least $1 billion (including obligations of foreign branches of such banks) and of the 75 largest foreign commercial banks in terms of total assets (including domestic branches of such banks); and repurchase agreements with respect to the foregoing obligations.

In times of adverse market conditions, the Fund may invest its assets without limit in high-quality short-term money market instruments.

The Fund generally utilizes leverage, and is authorized to use leverage in amounts of up to 33 1/3% of its total assets immediately after such borrowing and/or issuance (including the amount obtained from leverage).

The Fund may, in addition to engaging in the transactions described above, borrow money for temporary or emergency purposes (including, for example, clearance of transactions, share repurchases or payments of dividends to stockholders) in an amount not exceeding 5% of the value of the fund’s total assets (including the amount borrowed).

The Fund may enter into repurchase agreements for cash management purposes. Reverse repurchase agreements and similar investment management techniques that may provide leverage are not subject to the foregoing 33 1/3% limitation so long as the Fund has covered its commitment with respect to such techniques by segregating or earmarking liquid assets, entering into offsetting transactions or owning positions covering related obligations.

The Fund may engage in currency transactions with counterparties to hedge the value of portfolio securities denominated in particular currencies against fluctuations in relative value or to generate income or gain. Currency transactions include currency forward contracts, exchange-listed currency futures contracts and options thereon, exchange-listed and over-the-counter (“OTC”) options on currencies and currency swaps.

The Fund may use a variety of derivative instruments as part of its investment strategies or for hedging or risk management purposes. Examples of derivative instruments that the fund may use include options contracts, futures contracts, options on futures contracts, credit default swaps and other swap agreements. The Fund may purchase and sell futures contracts, purchase and sell (or write) exchange-listed and OTC put and call options on securities, financial indices and futures contracts, enter into various interest rate and currency transactions and enter into other similar transactions which may be developed in the future to the extent the management determines that they are consistent with the fund’s investment objectives and policies and applicable regulatory requirements. The Fund may use any or all of these techniques at any time, and the use of any particular derivative transaction will depend on market conditions.

The Fund may enter into interest rate swaps and may purchase interest rate caps, floors and collars and may sell interest rate caps, floors and collars that it has purchased

The Fund may also enter into (a) contracts for the purchase or sale for future delivery (“futures contracts”) of debt securities, aggregates of securities, indices based upon the prices thereof and other financial indices and (b) put or call options on such futures contracts.

The Fund may purchase or sell exchange-traded or OTC put or call options on securities and indices based upon the prices, yields or spreads of securities.

The Fund may purchase securities on a firm commitment basis, including when-issued securities. The Fund may also invest in delayed-delivery securities.

26

The Fund may lend portfolio securities to brokers or dealers or other financial institutions. The Fund does not currently intend to make loans of portfolio securities with a value in excess of 33 1/3% of the value of its total net assets.

The Fund may invest, without limitation, in illiquid securities, which are securities that cannot be sold within seven days at a price which the fund would determine to be fair value. The Fund may purchase Rule 144A securities for which there is a secondary market of qualified institutional buyers, as defined in Rule 144A promulgated under the Securities Act of 1933, as amended (the “Securities Act”). The Fund may purchase securities for which there is a limited trading market or which are subject to restrictions on resale to the public.

The Fund may invest in dollar rolls, asset-backed securities and mortgage-backed securities.

Percentage Limitations

Percentage limitations described in this prospectus are as of the time of investment by the Fund and may be exceeded on a going-forward basis as a result of credit rating downgrades or market value fluctuations of the Fund’s portfolio securities.

Segregation and Cover Requirements

Certain portfolio management techniques, such as reverse repurchase agreements, purchasing securities on a when-issued or delayed delivery basis, writing credit default swaps or futures contracts, engaging in short sales or writing options on portfolio securities, may be considered senior securities under the 1940 Act unless appropriate steps are taken to segregate the Fund’s assets or otherwise cover its obligations. If the Fund utilizes these portfolio management techniques, it may segregate liquid assets, enter into offsetting transactions or own positions covering related obligations. Although under no obligation to do so, Western Asset currently intends to cover the Fund’s commitment with respect to such techniques should the Fund enter into or engage in one or more of such management techniques. Under current law, to the extent the Fund covers its commitment under such portfolio management techniques, such instrument will not be considered a senior security for the purposes of the 1940 Act. The Fund may cover such transactions using other methods currently or in the future permitted under the 1940 Act, the rules and regulations thereunder, or orders issued by the SEC thereunder. For these purposes, interpretations and guidance provided by the SEC staff may be taken into account when deemed appropriate by the Fund. These segregation and coverage requirements could result in the Fund maintaining securities positions that it would otherwise liquidate, segregating assets at a time when it might be disadvantageous to do so or otherwise restricting portfolio management. Such segregation and cover requirements will not limit or offset losses on related positions. See “Investment Policies and Techniques—Portfolio Composition—Derivatives—Use of Segregated and Other Special Accounts” in the SAI. The SEC adopted a new rule on October 28, 2020 that will replace these asset segregation requirements with a requirement to ensure the Fund has a derivatives risk management program consistent with the new rule, including compliance with a VaR test. The Fund will not be required to comply with the new rule until August 19, 2022.

Portfolio Composition

Additional information regarding the Fund’s investment policies, restrictions and portfolio investments is contained in the SAI.

Temporary Defensive Strategies

The Fund may take temporary defensive positions or depart from its principal investment strategies in response to or anticipation of adverse or unusual market, economic, political or other conditions, including by investing in any type of money market instruments and short-term debt securities or holding cash or cash items without regard to any percentage limitations. For instance, for temporary defensive purposes, the Fund may restrict the markets in which it invests or may hold uninvested cash or invest without limitation in cash equivalents such as money market instruments, U.S. Treasury bills, interests in short-term investment funds, repurchase agreements, or shares of money market or short-term bond funds, even if the investments are inconsistent with the Fund’s principal

27

investment strategies. To the extent the Fund invests in these temporary investments in this manner, the Fund may succeed in avoiding losses but may not otherwise achieve its investment objective. Although Western Asset has the ability to take defensive positions for the Fund, it may choose not to do so for a variety of reasons, even during volatile market condition.

Portfolio Turnover

The Fund does not have a formal portfolio turnover policy and does not intend to adopt one. Although the Fund generally intends to hold most of its securities until maturity, it may, from time to time, sell any of its securities as part of its overall management of its investment portfolio. When investments are realized, Western Asset will reinvest proceeds therefrom in the Fund’s target assets. Depending on market conditions, Western Asset will also make opportunistic dispositions of the Fund’s investments in its target assets. Frequent trading also increases transaction costs, which could detract from the Fund’s performance.

Regulation as a “Commodity Pool”

The Commodity Futures Trading Commission (the “CFTC”) subjects advisers to registered investment companies to regulation by the CFTC if a fund that is advised by the investment adviser either (i) invests, directly or indirectly, more than a prescribed level of its liquidation value in CFTC-regulated futures, options and swaps (“CFTC Derivatives”), or (ii) markets itself as providing investment exposure to such instruments. To the extent the Fund uses CFTC Derivatives, it intends to do so below such prescribed levels and will not market itself as a “commodity pool” or a vehicle for trading such instruments. Accordingly, the Manager has claimed an exclusion from the definition of the term “commodity pool operator” under the Commodity Exchange Act (“CEA”) pursuant to Rule 4.5 under the CEA. The Manager is not, therefore, subject to registration or regulation as a “commodity pool operator” under the CEA in respect of the Fund

Fundamental Investment Policies

The Fund’s (i) investment objectives and (ii) the specified investment restrictions listed in the SAI, are considered fundamental and may not be changed without the approval of the holders of a majority of the outstanding voting securities (as defined in the 1940 Act). A “majority of the outstanding voting securities” means (i) 67% or more of the Fund’s outstanding voting securities present at a meeting, if the holders of more than 50% of the Fund’s outstanding voting securities are present or represented by proxy at the meeting or (ii) more than 50% of the outstanding voting securities, whichever of (i) or (ii) is less. See “Investment Restrictions” in the SAI for a complete list of the fundamental investment policies of the Fund.

28

LEVERAGE

The Fund may seek to enhance the level of its current distributions to Common Stockholders through the use of leverage.

The Fund may use leverage through borrowings, including loans from certain financial institutions and/or the issuance of debt securities (collectively, “Borrowings”), and through the issuance of shares of preferred stock (“Preferred Stock”). The Fund may use leverage through Borrowings in an aggregate amount of up to approximately 33 1/3% of the Fund’s total net assets immediately after such Borrowings. Furthermore, the Fund may use leverage through the issuance of Preferred Stock in an aggregate amount of liquidation preference attributable to the Preferred Stock combined with the aggregate amount of any Borrowings of up to approximately 50% of the Fund’s total net assets immediately after such issuance. The Fund may enter into reverse repurchase agreements and use similar investment management techniques that may provide leverage, but which are not subject to the foregoing 33 1/3% limitation so long as the Fund has covered its commitment with respect to such techniques by segregating or earmarking liquid assets, entering into offsetting transactions or owning positions covering related obligations. The Fund has a revolving credit agreement with Pershing LLC (“Credit Agreement”) that allows the Fund to borrow up to an aggregate amount of $300,000,000, subject to approval by Pershing LLC. On March 10, 2022, the Board approved a consent and amendment agreement whereby Pershing transferred its interest in the Credit Agreement to the Bank of New York Mellon. The Fund pays interest on Borrowings calculated based on the Overnight Bank Funding Rate plus applicable margin. The Overnight Bank Funding Rate means the Overnight Bank Funding Rate as reported by the New York Federal Reserve in the FR2420 Report of Selected Money Market Rates or any successor report or website. To the extent of the borrowing outstanding, the Fund is required to maintain collateral in a special custody account at the Fund’s custodian on behalf of Pershing LLC. The Fund’s Credit Agreement contains customary covenants that, among other things, may limit the Fund’s ability to pay distributions in certain circumstances, incur additional debt, change its fundamental investment policies and engage in certain transactions, including mergers and consolidations, and require asset coverage ratios in addition to those required by the 1940 Act. In addition, the Credit Agreement may be subject to early termination under certain conditions and may contain other provisions that could limit the Fund’s ability to utilize borrowing under the agreement. As of April 30, 2021, the Fund had $158,000,000 of Borrowings outstanding.

The SEC has adopted new Rule 18f-4 under the 1940 Act, which will require a fund that is not a “limited derivatives user” as described in Rule 18f-4(c)(4) to adopt a derivatives risk management program providing for specific items as required by the rule, including compliance with a VaR test. The provisions of Rule 18f-4 will replace the 1940 Act cover requirements for reverse repurchase agreements, similar financing transactions and derivatives transactions discussed in this Prospectus. Under Rule 18f-4(d), a fund may enter into reverse repurchase agreements or similar financing transactions in reliance on the rule if the fund either (i) complies with the asset coverage requirements of Section 18 of the 1940 Act, and combines the aggregate amount of indebtedness associated with all reverse repurchase agreements or similar financing transactions with the aggregate amount of any other senior securities representing indebtedness when calculating its asset coverage ratio; or (ii) treats all reverse repurchase agreements or similar financing transactions as derivatives transactions for all purposes under the rule. Compliance with Rule 18f-4 will be required by August 19, 2022. Using derivatives also can have a leveraging effect and increase Fund volatility.

The Fund currently expects to use leverage through the issuance of Preferred Stock. Borrowings (and any Preferred Stock) will have seniority over Common Stock. Any Borrowings and Preferred Stock (if issued) will leverage your investment in Common Stock. Holders of Common Stock will bear the costs associated with any Borrowings, and if the Fund issues Preferred Stock, Common Stockholders will bear the offering costs of the Preferred Stock issuance. The Board of Directors of the Fund may authorize the use of leverage through Borrowings and Preferred Stock without the approval of the Common Stockholders.

Changes in the value of the Fund’s portfolio securities, including costs attributable to Borrowings or Preferred Stock, will be borne entirely by the holders of the Common Stock. If there is a net decrease (or increase) in the value of the Fund’s investment portfolio, the leverage will decrease (or increase) the net asset value per share of Common Stock to a greater extent than if the Fund were not leveraged. During periods when the Fund is using leverage through Borrowings or the issuance of Preferred Stock the fees paid to the Manager, Western Asset,

29

Western Asset Limited and Western Asset Singapore for advisory services will be higher than if the Fund did not use leverage because the fees paid will be calculated on the basis of the Fund’s Managed Assets, which includes the principal amount of the Borrowings and any assets attributable to the issuance of Preferred Stock. This means that the Manager, Western Asset, Western Asset Limited and Western Asset Singapore may have a financial incentive to increase the Fund’s use of leverage.

Under the 1940 Act, the Fund generally is not permitted to issue commercial paper or notes or borrow unless immediately after the borrowing or commercial paper or note issuance the value of the Fund’s total assets less liabilities other than the principal amount represented by commercial paper, notes or borrowings is at least 300% of such principal amount. In addition, the Fund is not permitted to declare any cash dividend or other distribution on its Common Stock unless, at the time of such declaration, the value of the Fund’s total assets, less liabilities other than the principal amount represented by commercial paper, notes or borrowings, is at least 300% of such principal amount after deducting the amount of such dividend or distribution. If the Fund borrows, the Fund intends, to the extent possible, to prepay all or a portion of the principal amount of any outstanding commercial paper, notes or borrowing to the extent necessary to maintain the required asset coverage. Failure to maintain certain asset coverage requirements could result in an event of default and entitle the debt holders to elect a majority of the Board of Directors.

Utilization of leverage is a speculative investment technique and involves certain risks to the holders of Common Stock. These include the possibility of higher volatility of the net asset value of the Common Stock and potentially more volatility in the market value of, and distributions on, the Common Stock. So long as the Fund is able to realize a higher net return on its investment portfolio than the then-current cost of any leverage together with other related expenses, the effect of the leverage will be to cause holders of Common Stock to realize a higher rate of return than if the Fund were not so leveraged. On the other hand, to the extent that the then-current cost of any leverage, together with other related expenses, approaches the net return on the Fund’s investment portfolio, the benefit of leverage to holders of Common Stock will be reduced, and if the then-current cost of any leverage together with related expenses were to exceed the net return on the Fund’s portfolio, the Fund’s leveraged capital structure would result in a lower rate of return to holders of Common Stock than if the Fund were not so leveraged. There can be no assurance that the Fund’s leveraging strategy will be successful.

Under the 1940 Act, the Fund is not permitted to issue Preferred Stock unless immediately after such issuance the value of the Fund’s asset coverage is at least 200% of the liquidation value of the outstanding Preferred Stock (i.e., such liquidation value may not exceed 50% of the Fund’s asset coverage less all liabilities other than borrowings).

In addition, the Fund is not permitted to declare any cash dividend or other distribution on its Common Stock unless, at the time of such declaration, the value of the Fund’s asset coverage less liabilities other than borrowings satisfies the above-referenced 200% coverage requirement. If Preferred Stock is issued, the Fund intends, to the extent possible, to purchase or redeem Preferred Stock from time to time to the extent necessary in order to maintain coverage of at least 200%.

If Preferred Stock is outstanding, two of the Fund’s Directors will be elected by the holders of Preferred Stock, voting separately as a class. The remaining Directors of the Fund will be elected by holders of Common Stock and Preferred Stock voting together as a single class. In the unlikely event that the Fund fails to pay dividends on the Preferred Stock for two years, holders of Preferred Stock would be entitled to elect a majority of the Directors of the Fund. The failure to pay dividends or make distributions could result in the Fund ceasing to qualify for taxation as a regulated investment company under the Code, which could have a material adverse effect on the value of the Common Stock.

The Fund may be subject to certain restrictions imposed either by guidelines of a lender, if the Fund borrows from a lender, or by one or more rating agencies which may issue ratings for Preferred Stock or debt securities. These guidelines may impose asset coverage or portfolio composition requirements that are more stringent than those imposed on the Fund by the 1940 Act. It is not anticipated that these covenants or guidelines will impede the Manager, Western Asset, Western Asset Limited and Western Asset Singapore from managing the Fund’s portfolio in accordance with the Fund’s investment objectives and policies. In addition to other considerations, to the extent that the Fund believes that the covenants and guidelines required by the rating agencies would impede its ability to meet its investment objectives, or if the Fund is unable to obtain its desired rating on Preferred Stock or debt securities, the Fund will not issue Preferred Stock or debt securities.

Effects of Leverage

The Fund may borrow up to an aggregate amount of $300,000,000 under its revolving credit agreement. As of April 30, 2021, the Fund had $158,000,000 of Borrowings outstanding per this credit agreement. The credit agreement is currently scheduled to terminate on May 11, 2022.

The following table is furnished in response to requirements of the SEC. It is designed to illustrate the effect of leverage on Common Stock total return, assuming investment portfolio total returns (comprised of income and changes in the value of securities held in the Fund’s portfolio) of -10%, -5%, 0%, 5% and 10%. These assumed investment portfolio returns are hypothetical figures and are not necessarily indicative of the investment portfolio returns experienced or expected to be experienced by the Fund. See “Risks.”

The table further reflects the issuance of leverage representing 29% of the Fund’s total net assets, net of expenses. The Fund’s currently projected annual interest on its leverage of 0.87%.

Common Stock Total Return is composed of two elements: the Common Stock dividends paid by the Fund (the amount of which is largely determined by the net investment income of the Fund after paying dividends or interest on its leverage) and gains or losses on the value of the securities the Fund owns. As required by SEC rules, the table above assumes that the Fund is more likely to suffer capital losses than to enjoy capital appreciation. For example, to assume a total return of 0% the Fund must assume that the interest it receives on its debt security investments is entirely offset by losses in the value of those investments.

31

RISKS

The Fund is a diversified, closed-end management investment company designed primarily as a long-term investment and not as a trading vehicle. The Fund is not intended to be a complete investment program and, due to the uncertainty inherent in all investments, there can be no assurance that the Fund will achieve its investment objectives. The Fund’s performance and the value of its investments will vary in response to changes in interest rates, inflation, the financial condition of a security’s issuer, ratings on a security and other market factors. Your securities at any point in time may be worth less than you invested, even after taking into account the reinvestment of Fund dividends and distributions. Below are the principal risks associated with an investment in the Fund.

Investment Risk and Market Risk

An investment in the Fund is subject to investment risk, including the possible loss of the entire principal amount that you invest. Your investment in the Fund represents an indirect investment in the securities owned by the Fund. The value of these securities may increase or decrease, at times rapidly and unexpectedly. Your investment in the Fund may at any point in the future be worth less than your original investment even after taking into account the reinvestment of dividends and distributions.

Below Investment Grade Securities (High-Yield) Risk

At any one time, substantially all of the Fund’s Managed Assets may be invested in high-yield debt securities. High yield debt securities are generally subject to greater credit risks than higher-grade debt securities, including the risk of default on the payment of interest or principal. High yield debt securities are considered speculative, typically have lower liquidity and are more difficult to value than higher grade bonds. High yield debt securities tend to be volatile and more susceptible to adverse events, credit downgrades and negative sentiments and may be difficult to sell at a desired price, or at all, during periods of uncertainty or market turmoil. Because of the substantial risks associated with investments in lower grade securities, you could lose money on your investment in Common Stock, both in the short-term and the long-term.

Low Rated and Unrated Securities

The Fund may invest in instruments that are low rated or unrated. Debt securities of emerging market issuers may be considered to have a credit quality rated below investment grade by internationally recognized credit rating organizations such as Moody’s and S&P. Non-investment grade securities (that is, rated Ba1 or lower by Moody’s or BB+ or lower by S&P) are commonly referred to as “junk bonds” and are regarded as predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal in accordance with the terms of the obligations and involve major risk exposure to adverse conditions. Some of the emerging market issuer securities held by the Fund, which may not be paying interest currently or may be in payment default, may be comparable to securities rated as low as C by Moody’s or CCC or lower by S&P. These securities are considered to have extremely poor prospects of ever attaining any real investment standing, to have a current identifiable vulnerability to default, to be unlikely to have the capacity to pay interest and repay principal when due in the event of adverse business, financial or economic conditions and/or to be in default or not current in the payment of interest or principal.

Low rated and unrated debt instruments generally offer a higher current yield than that available from higher grade issues, but typically involve greater risk. Low rated and unrated securities are especially subject to adverse changes in general economic conditions, to changes in the financial condition of their issuers and to price fluctuation in response to changes in interest rates. During periods of economic downturn or rising interest rates, issuers of low rated and unrated instruments may experience financial stress that could adversely affect their ability to make payments of principal and interest and increase the possibility of default. Adverse publicity and investor perceptions, whether or not based on fundamental analysis, may also decrease the values and liquidity of low rated and unrated securities especially in a market characterized by a low volume of trading.

32

Default Risk

Investments in fixed-income securities are subject to the risk that the issuer of the security could default on its obligations, causing a fund to sustain losses on those investments. A default could impact both interest and principal payments. High-yield fixed-income securities (commonly known as “junk bonds”) are considered speculative with respect to the issuer’s capacity to pay interest and repay principal in accordance with the terms of the obligations. This means that, compared to issuers of higher rated securities, issuers of medium and lower rated securities are less likely to have the capacity to pay interest and repay principal when due in the event of adverse business, financial or economic conditions and/or may be in default or not current in the payment of interest or principal.

The market values of medium and lower rated securities tend to be more sensitive to company-specific developments and changes in economic conditions than higher rated securities. The companies that issue these securities often are highly leveraged, and their ability to service their debt obligations during an economic downturn or periods of rising interest rates may be impaired. In addition, these companies may not have access to more traditional methods of financing, and may be unable to repay debt at maturity by refinancing. The risk of loss due to default in payment of interest or principal by these issuers is significantly greater than with higher rated securities because medium and lower rated securities generally are unsecured and subordinated to senior debt.

Default, or the market’s perception that an issuer is likely to default, could reduce the value and liquidity of securities held by the Fund, thereby reducing the value of your investment in the Common Stock. In addition, default may cause the Fund to incur expenses in seeking recovery of principal or interest on its portfolio holdings.

Foreign (Non-U.S.) Investment Risk

A fund that invests in foreign (non-U.S.) securities may experience more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies. The securities markets of many foreign countries are relatively small, with a limited number of companies representing a small number of industries. Investments in foreign securities (including those denominated in U.S. dollars) are subject to economic and political developments in the countries and regions where the issuers operate or are domiciled, or where the securities are traded, such as changes in economic or monetary policies. Values may also be affected by restrictions on receiving the investment proceeds from a foreign country. Less information may be publicly available about foreign companies than about U.S. companies. Foreign companies are generally not subject to the same accounting, auditing and financial reporting standards as are U.S. companies. In addition, the Fund’s investments in foreign securities may be subject to the risk of nationalization or expropriation of assets, imposition of currency exchange controls or restrictions on the repatriation of foreign currency, confiscatory taxation, political or financial instability and adverse diplomatic developments. In addition, there may be difficulty in obtaining or enforcing a court judgment abroad. Dividends or interest on, or proceeds from the sale of, foreign securities may be subject to non-U.S. withholding taxes, and special U.S. tax considerations may apply.

The risks of foreign investment are greater for investments in emerging markets. Emerging market countries typically have economic and political systems that are less fully developed, and that can be expected to be less stable, than those of more advanced countries. Low trading volumes may result in a lack of liquidity and in price volatility. Emerging market countries may have policies that restrict investment by foreigners, that require governmental approval prior to investments by foreign persons, or that prevent foreign investors from withdrawing their money at will. An investment in emerging market securities should be considered speculative.

Emerging Markets Risks

Investing in securities of emerging market issuers entails all of the risks of investing in securities of foreign issuers to a heightened degree. The heightened risks include: (i) greater risks of expropriation, confiscatory taxation, nationalization, and less social, political and economic stability; (ii) the smaller size of the market for such securities and a lower volume of trading, resulting in lack of liquidity and in price volatility; and (iii) certain national policies which may restrict HIX’s investment opportunities, including restrictions on investing in issuers or industries deemed sensitive to relevant national interests.

Economic and Political Risks

The economies of individual emerging market countries may differ favorably or unfavorably from the U.S. economy in such respects as growth of gross domestic product, rate of inflation, currency depreciation, capital reinvestment, resource self-sufficiency and balance of payments position. Further, the economies of developing countries generally are heavily dependent upon international trade and, accordingly, have been and may continue to be adversely affected by trade barriers, exchange controls, managed adjustments in relative currency values and other protectionist measures imposed or negotiated by the countries with which they trade. These economies also have been and may continue to be adversely affected by economic conditions in the countries with which they trade.

With respect to any emerging market country, there is the possibility of nationalization, expropriation or confiscatory taxation, political changes, governmental regulation, social instability or diplomatic developments (including war) which could affect adversely the economies of such countries or the value of the Fund’s investments in those countries.

Risks Related to Russia’s Invasion of Ukraine

Russia’s military invasion of Ukraine in February 2022, the resulting responses by the United States and other countries, and the potential for wider conflict could increase volatility and uncertainty in the financial markets and adversely affect regional and global economies. The United States and other countries have imposed broad-ranging economic sanctions on Russia and certain Russian individuals, banking entities and corporations as a response to its invasion of Ukraine. The United States and other countries have also imposed economic sanctions on Belarus and may impose sanctions on other countries that support Russia’s military invasion. These sanctions, as well as any other economic consequences related to the invasion, such as additional sanctions, boycotts or changes in consumer or purchaser preferences or cybersecurity attacks on governments, companies or individuals, may further decrease the value and liquidity of certain Russian securities and securities of issuers in other countries that are subject to economic sanctions related to the invasion. To the extent that the Fund has exposure to Russian investments or investments in countries affected by the invasion, the Fund’s the ability to price, buy, sell, receive or deliver such investments may be impaired. The Fund could determine at any time that certain of the most affected securities have zero value. In addition, any exposure that the Fund may have to counterparties in Russia or in countries affected by the invasion could negatively impact the Fund’s portfolio. The extent and duration of Russia’s military actions and the repercussions of such actions (including any retaliatory actions or countermeasures that may be taken by those subject to sanctions) are impossible to predict, but could result in significant market disruptions, including in the oil and natural gas markets, and may negatively affect global supply chains, inflation and global growth. These and any related events could significantly impact the Fund’s performance and the value of an investment in the Fund, even beyond any direct exposure the Fund may have to Russian issuers or issuers in other countries affected by the invasion.

33

Investment Controls; Repatriation

Foreign investment in certain emerging market issuers is restricted or controlled to varying degrees. These restrictions or controls may at times limit or preclude foreign investment in certain emerging market issuers and increase the costs and expenses of the Fund. Certain emerging market countries require governmental approval prior to investments by foreign persons in a particular issuer, limit the amount of investment by foreign persons in a particular issuer, limit the investment by foreign persons only to a specific class of securities of an issuer that may have less advantageous rights than the classes available for purchase by domiciliaries of the countries and/or impose additional taxes on foreign investors. Certain emerging market countries may also restrict investment opportunities in issuers in industries deemed important to national interests.

Emerging market countries may require governmental approval for the repatriation of investment income, capital or the proceeds of sales of securities by foreign investors. In addition, if a deterioration occurs in an emerging market country’s balance of payments, the country could impose temporary restrictions on foreign capital remittances. The Fund could be adversely affected by delays in, or a refusal to grant, any restrictions on investments. Investing in local markets in emerging market countries may require the Fund to adopt special procedures, seek local government approvals or take other actions, each of which may involve additional costs to the Fund.

Market Illiquidity

No established secondary markets may exist for many of the emerging market issuer securities in which the Fund may invest. Reduced secondary market liquidity may have an adverse effect on market price and the Fund’s ability to dispose of particular instruments when necessary to meet its liquidity requirements or in response to specific economic events such as a deterioration in the creditworthiness of the issuer. Reduced secondary market liquidity for certain emerging market issuer securities may also make it more difficult for the Fund to obtain accurate market quotations for purposes of valuing its portfolio and calculating its net asset value. Market quotations are generally available on many emerging market issuer securities only from a limited number of dealers and may not necessarily represent firm bids of those dealers or prices for actual sales.

Currency Devaluations and Fluctuations

The value of investments in securities denominated in foreign currencies increases or decreases as the rates of exchange between those currencies and the U.S. dollar change. Currency conversion costs and currency fluctuations could erase investment gains or add to investment losses. Currency exchange rates can be volatile, and are affected by factors such as general economic conditions, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls and speculation. The Fund may be unable or may choose not to hedge its foreign currency exposure.

Financial Information and Standards

Issuers in emerging market countries generally are subject to accounting, auditing and financial standards and requirements that differ, in some cases significantly, from those applicable to U.S. issuers. In particular, the assets and profits appearing on the financial statements of an emerging market country issuer may not reflect its financial position or results of operations in the way they would be reflected had the financial statements been prepared in accordance with U.S. generally accepted accounting principles. In addition, for an issuer that keeps accounting records in local currency, inflation accounting rules may require that certain assets and liabilities be restated on the issuer’s balance sheet in order to express items in terms of currency of constant purchasing power. Inflation accounting may indirectly generate losses or profits. Consequently, financial data may be materially affected by restatements for inflation and may not accurately reflect the real condition of those issuers and securities markets. Substantially less information may be publicly available about issuers in emerging market countries than is available about U.S. issuers.

34

Smaller Company Risk

The general risks associated with income-producing securities are particularly pronounced for securities issued by companies with smaller market capitalizations. These companies may have limited product lines, markets or financial resources or they may depend on a few key employees. As a result, they may be subject to greater levels of credit, market and issuer risk. Securities of smaller companies may trade less frequently and in lesser volume than more widely held securities and their values may fluctuate more sharply than other securities. Companies with medium-sized market capitalizations may have risks similar to those of smaller companies.

Interest Rate Risk

The market price of the Fund’s investments will change in response to changes in interest rates and other factors. During periods of declining interest rates, the market price of fixed income securities generally rises. Conversely, during periods of rising interest rates, the market price of such securities generally declines. The magnitude of these fluctuations in the market price of fixed income securities is generally greater for securities with longer maturities. Additionally, such risk may be greater during the current period of historically low interest rates. Fluctuations in the market price of the Fund’s securities will not affect interest income derived from securities already owned by the Fund, but will be reflected in the Fund’s net asset value. The Fund may utilize certain strategies, including investments in structured notes or interest rate swap or cap transactions, for the purpose of reducing the interest rate sensitivity of the portfolio and decreasing the Fund’s exposure to interest rate risk, although there is no assurance that it will do so or that such strategies will be successful.

Credit Risk and Counterparty Risk

The value of your investment in the Fund could decline if the issuer of a security held by the Fund or another obligor for that security (such as a party offering credit enhancement) or a counterparty to a financial contract with the Fund fails to pay, otherwise defaults, is perceived to be less creditworthy, becomes insolvent or files for bankruptcy. The value of your investment in the Fund could also decline if the credit rating of a security held by the Fund is downgraded or the credit quality or value of any assets underlying the security or financial contract declines. If the Fund enters into financial contracts (such as certain derivatives, repurchase agreements, reverse repurchase agreements, and when-issued, delayed delivery and forward commitment transactions), the Fund will be subject to the credit risk presented by the counterparty and any custodian of Fund assets. In addition, the Fund may incur expenses in an effort to protect the Fund interests or to enforce its rights against an issuer, guarantor, counterparty or any custodian or may be hindered or delayed in exercising those rights. Credit risk is broadly gauged by the credit ratings of the securities in which the Fund invests and the credit ratings of counterparties to financial contracts with the Fund. However, ratings are only the opinions of the companies issuing them and are not guarantees as to quality. Securities rated in the lowest category of investment grade (Baa/BBB) may possess certain speculative characteristics. Credit risk is typically greatest for the Fund’s high yield debt securities, which are rated below the Baa/BBB categories or unrated securities of comparable quality (“junk” bonds).

The Fund may invest in securities which are subordinated to more senior securities of the issuer, or which represent interests in pools of such subordinated securities. The Fund is more likely to suffer a credit loss on subordinated securities than on non-subordinated securities of the same issuer. If there is a default, bankruptcy or liquidation of the issuer, most subordinated securities are paid only if sufficient assets remain after payment of the issuer’s non-subordinated securities. In addition, any recovery of interest or principal may take more time. As a result, even a perceived decline in creditworthiness of the issuer is likely to have a greater adverse impact on subordinated securities.

Reinvestment Risk

Reinvestment risk is the risk that income from the Fund’s portfolio will decline if and when the Fund invests the proceeds from matured, traded or called debt obligations at market interest rates that are below the portfolio’s current earnings rate. A decline in income could affect the price of Common Stock or the Fund’s overall return.

35

Liquidity Risk

The Fund has no limit on its ability to purchase illiquid securities. Liquidity risk exists when particular investments are difficult to sell. Securities may become illiquid after purchase by the Fund, particularly during periods of market turmoil. When the Fund holds illiquid investments, the portfolio may be harder to value, especially in changing markets, and if the Fund is forced to sell these investments in order to segregate assets or for other cash needs, the Fund may suffer a loss.

Duration Risk

The duration of a fixed-income security is a measure of the portfolio’s sensitivity to changes in interest rates. Prices of fixed-income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities. Holding long duration investments may expose the Fund to certain magnified risks. These include interest rate risk, credit risk and liquidity risk, as discussed above.

Management Risk

The Fund is subject to management risk because it is an actively managed investment portfolio. The Manager and each individual portfolio manager will apply investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these will produce the desired results.

Leverage Risk

The Fund generally utilizes leverage, and is authorized to use leverage in amounts of up to approximately 33 1/3% of its total assets immediately after such borrowing and/or issuance, and under current market conditions intends to continue to use leverage. The value of your investment may be more volatile if the fund borrows or uses instruments, such as derivatives, that have a leveraging effect on the fund’s portfolio. Other risks described in the Prospectus also will be compounded because leverage generally magnifies the effect of a change in the value of an asset and creates a risk of loss of value on a larger pool of assets than the fund would otherwise have had. The fund may also have to sell assets at inopportune times to satisfy its obligations created by the use of leverage or derivatives. The use of leverage is considered to be a speculative investment practice and may result in the loss of a substantial amount, and possibly all, of the fund’s assets. In addition, the fund’s portfolio will be leveraged if it exercises its right to delay payment on a redemption, and losses will result if the value of the fund’s assets declines between the time a redemption request is deemed to be received by the fund and the time the fund liquidates assets to meet redemption requests.

Derivatives Risk

The Fund may utilize a variety of derivative instruments for investment or risk management purposes, such as options, futures contracts, swap agreements and credit default swaps. Using derivatives can increase Fund losses and reduce opportunities for gains when market prices, interest rates, currencies, or the derivatives themselves behave in a way not anticipated by the Fund. Using derivatives also can have a leveraging effect and increase Fund volatility. Certain derivatives have the potential for unlimited loss, regardless of the size of the initial investment. Derivatives may not be available at the time or price desired, may be difficult to sell, unwind or value, and the counterparty may default on its obligations to the Fund. Derivatives are generally subject to the risks applicable to the assets, rates, indices or other indicators underlying the derivative. The value of a derivative may fluctuate more than the underlying assets, rates, indices or other indicators to which it relates. Use of derivatives may have different tax consequences for the Fund than an investment in the underlying security, and those differences may affect the amount, timing and character of income distributed to shareholders. The U.S. government and foreign governments are in the process of adopting and implementing regulations governing derivatives markets, including mandatory clearing of certain derivatives, margin and reporting requirements. The ultimate impact of the regulations remains unclear. Additional regulation of derivatives may make derivatives more costly, limit their availability or utility, otherwise adversely affect their performance or disrupt markets.

The Securities and Exchange Commission adopted a new rule on October 28, 2020 that mandates that a fund’s derivatives risk management program provide for specific items as required by the rule, including compliance with a VaR test. Compliance with these new requirements will be required after a transition period that ends on

36

August 19, 2022. Following the compliance date, these requirements may limit the ability of the Fund to use derivatives and reverse repurchase agreements and similar financing transactions as part of its investment strategies. These requirements may increase the cost of the Fund’s investments in derivatives, which could adversely affect shareholders.

Credit default swap contracts involve heightened risks and may result in losses to the Fund. Credit default swaps may be illiquid and difficult to value. When the Fund sells credit protection via a credit default swap, credit risk increases since the Fund has exposure to both the issuer whose credit is the subject of the swap and the counterparty to the swap.

Dollar Rolls, Asset-Backed Securities and Mortgage-Backed Securities Risk

The Fund may invest in dollar rolls, asset-backed securities and mortgage-backed securities. Under a dollar roll transaction, the Fund sells securities for delivery in the current month, or sells securities it has purchased on a “to-be-announced” basis, and simultaneously contracts to repurchase substantially similar (same type and coupon) securities on a specified future date. During the roll period, the Fund forgoes principal and interest paid on the purchased securities. Dollar rolls are speculative techniques involving leverage, and are considered Borrowings by the Fund if the Fund does not establish and maintain a segregated account. In addition, dollar rolls involve the risk that the market value of the securities the Fund is obligated to repurchase may decline below the repurchase price. In the event the buyer of securities under a dollar roll files for bankruptcy or becomes insolvent, the Fund’s use of proceeds 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. Successful use of dollar rolls may depend upon the ability of the Fund’s investment manager to correctly predict interest rates and prepayments. There is no assurance that dollar rolls can be successfully employed.

Mortgage-backed securities may be issued by private companies or by agencies of the U.S. Government and represent direct or indirect participations in, or are collateralized by and payable from, mortgage loans secured by real property. Asset-backed securities represent participations in, or are secured by and payable from, assets such as installment sales or loan contracts, leases, credit card receivables and other categories of receivables. Certain debt instruments may only pay principal at maturity or may only represent the right to receive payments of principal or payments of interest on underlying pools of mortgages, assets or government securities, but not both. The value of these types of instruments may change more drastically than debt securities that pay both principal and interest during periods of changing interest rates. The Fund may obtain a below market yield or incur a loss on such instruments during periods of declining interest rates. Principal only and interest only instruments are subject to extension risk. For mortgage derivatives and structured securities that have imbedded leverage features, small changes in interest or prepayment rates may cause large and sudden price movements. Mortgage derivatives may be illiquid and hard to value in declining markets.

Interest Rate Transactions Risk

The Fund may enter into a swap or cap transaction to attempt to protect itself from increasing interest expenses on Borrowings resulting from increasing short-term interest rates or dividend expenses on any preferred shares. A decline in interest rates may result in a decline in net amounts receivable by the Fund from the counterparty under the swap or cap (or an increase in the net amounts payable by the Fund to the counterparty under the swap), which may result in a decline in the net asset value of the Fund.

Risks of Warrants and Rights

Warrants and rights are subject to the same market risks as stocks, but may be more volatile in price. Warrants and rights do not carry the right to dividends or voting rights with respect to their underlying securities, and they do not represent any rights in the assets of the issuer. An investment in warrants or rights may be considered speculative. In addition, the value of a warrant or right does not necessarily change with the value of the underlying security and a warrant or right ceases to have value if it is not exercised prior to its expiration date. The purchase of warrants or rights involves the risk that the Fund could lose the purchase value of a warrant or right if the right to subscribe to additional shares is not exercised prior to the warrants’ or rights’ expiration. Also, the purchase of warrants and rights involves the risk that the effective price paid for the warrant or right added to the subscription price of the related security may exceed the value of the subscribed security’s market price such as when there is no movement in the price of the underlying security.

37

Market Price Discount from Net Asset Value

Shares of closed-end investment companies frequently trade at a discount from their net asset value. This risk is separate and distinct from the risk that the Fund’s net asset value could decrease as a result of its investment activities and may be a greater risk to investors expecting to sell their Common Stock in a relatively short period following completion of this offering. Whether investors will realize gains or losses upon the sale of the Common Stock will depend not upon the Fund’s net asset value but upon whether the market price of the Common Stock at the time of sale is above or below the investor’s purchase price for the Common Stock.

Inflation/Deflation Risk

Inflation risk is the risk that the value of certain assets or income from the Fund’s investments will be worth less in the future as inflation decreases the value of money. As inflation increases, the real value of the Common Stock and distributions on the Common Stock can decline. In addition, during any periods of rising inflation, the dividend rates or borrowing costs associated with the Fund’s use of leverage would likely increase, which would tend to further reduce returns to stockholders. Current economic indicators have shown inflation accelerating at a faster pace than in recent years. Deflation risk is the risk that prices throughout the economy decline over time—the opposite of inflation.

Deflation may have an adverse effect on the creditworthiness of issuers and may make issuer defaults more likely, which may result in a decline in the value of the Fund’s portfolio.

Energy and Energy Infrastructure Sector Risk

The Fund is subject to the risk of investments in the energy sector, which makes it more susceptible to factors adversely affecting issuers within that industry than would a fund investing in a more diversified portfolio of securities. A downturn in the energy sector of the economy could have an adverse impact on the Fund. At times, the performance of securities of companies in the energy sector of the economy may lag the performance of other sectors or the broader market as a whole. The profitability of companies in the energy infrastructure sector is related to worldwide energy prices and costs related to energy production. The energy sector is cyclical and highly dependent on commodity prices. Energy-related companies can be significantly affected by the supply of, and demand for, particular energy products (such as oil and natural gas). Companies in the energy infrastructure sector may be adversely affected by natural disasters or other catastrophes. These companies may be at risk for environmental damage claims and other types of litigation. Companies in the energy infrastructure sector also may be adversely affected by changes in exchange rates, interest rates, economic conditions, tax treatment, government regulation and intervention, negative perception, efforts at energy conservation and world events in the regions in which the companies operate (e.g., expropriation, nationalization, confiscation of assets and property or the imposition of restrictions on foreign investments and repatriation of capital, military coups, social unrest, violence or labor unrest). Companies in the energy infrastructure sector may have significant capital investments in, or engage in transactions involving, emerging market countries, which may heighten these risks.

Hospitality and Leisure Sector Risk

To the extent the Fund’s investments are exposed to issuers conducting business in the hospitality and leisure sectors, the Fund will be subject to the risks of such sectors. The hospitality sector is highly competitive and influenced by factors such as general and local economic conditions, location, room rates, quality, service levels, reputation and reservation systems, among many other factors. The hospitality or leisure industry generally experiences seasonal slowdown in the third quarter and, to a lesser extent, in the fourth quarter of each year. As a result of such seasonality, there may be fluctuations in results of operations of any hospitality or leisure investments the Fund holds. The demand for such leisure activities often changes rapidly. The leisure industry can be significantly affected by the performance of the overall economy, changing consumer tastes, intense competition, technological developments, and government regulation. In addition, any such investments that the Fund may hold may be adversely affected by unknown and unpredictable factors, such as extreme weather conditions or natural disasters, terrorist attacks or alerts, outbreaks of contagious diseases, airline strikes, economic factors and other considerations affecting travel.

Market Events Risk

The market values of securities or other assets will fluctuate, sometimes sharply and unpredictably, due to changes in general market conditions, overall economic trends or events, governmental actions or intervention, actions taken by the U.S. Federal Reserve or foreign central banks, market disruptions caused by trade disputes or other factors, political developments, investor sentiment, the global and domestic effects of a pandemic, and other factors that may or may not be related to the issuer of the security or other asset. Economies and financial markets throughout the world are increasingly interconnected. Economic, financial or political events, trading and tariff arrangements, public health events, terrorism, natural disasters and other circumstances in one country or region could have profound impacts on global economies or markets. As a result, whether or not the Fund invests in securities of issuers located in or with significant exposure to the countries directly affected, the value and liquidity of the Fund’s investments may be negatively affected.

The current global outbreak of the novel strain of coronavirus, COVID-19, has resulted in market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. Efforts to contain the spread of COVID-19 have resulted in global travel restrictions and disruptions of healthcare systems, business operations and supply chains, layoffs, reduced consumer demand, defaults and credit ratings downgrades, and other significant economic impacts. The effects of COVID-19 have impacted global economic activity across many industries and may heighten other pre-existing political, social and economic risks, locally or globally. The full impact of the COVID-19 pandemic is unpredictable and may adversely affect the Fund’s performance.

Legislative and Regulatory Risk

Prices for high-yield securities may be affected by legislative and regulatory developments which could adversely affect the Fund’s net asset value and investment practices, the secondary market for high-yield securities, the financial condition of issuers of these securities and the value of outstanding high-yield securities. These risks generally are higher than issuers in emerging market countries.

38

Anti-Takeover Provisions Risk

The Fund’s Charter and Bylaws include provisions that are designed to limit the ability of other entities or persons to acquire control of the Fund for short-term objectives, including by converting the Fund to open-end status or changing the composition of the Board, that may be detrimental to the Fund’s ability to achieve its primary investment objective of seeking high current income. The Fund’s Charter also contains a provision opting in to the provisions of the MCSAA subject to certain exceptions. Such provisions may limit the ability of shareholders to sell their shares at a premium over prevailing market prices by discouraging a third party from seeking to obtain control of the Fund. There can be no assurance, however, that such provisions will be sufficient to deter activist investors that seek to cause the Fund to take actions that may not be aligned with the interests of long-term shareholders. See “Certain Provisions in the Charter and Bylaws” and “Certain Provisions in the Charter and Bylaws—Maryland Control Share Acquisition Act.” A recent decision by the U.S. District Court for the Southern District of New York held that a control share amendment to the bylaws of a closed-end fund organized in Massachusetts was inconsistent with Section 18(i) of the 1940 Act. This decision did not address whether a closed-end fund organized in Maryland that opts in to the MCSAA violates Section 18(i). Moreover, the New York decision appears to be incompatible with a prior decision by the U.S. District Court for the District of Maryland, which permitted a closed-end fund organized in Maryland to remain opted in to the MCSAA notwithstanding a counterclaim alleging that the fund’s decision to opt in to the MCSAA violated Section 18(i) of the 1940 Act. Nonetheless, there is a risk that a court could follow the reasoning of the New York federal court, as opposed to the decision of the Maryland federal court, when determining whether a closed-end fund organized in Maryland can opt in to the MCSAA.

LIBOR Risk

The Fund’s investments, payment obligations, and financing terms may be based on floating rates, such as LIBOR, which is the offered rate for short-term Eurodollar deposits between major international banks. On March 5, 2021, the ICE Benchmark Administration, the administrator of LIBOR, stated that it will cease the publication of (i) the overnight and one-, three-, six- and twelve-month USD LIBOR settings immediately following the LIBOR publication on Friday, June 30, 2023 and (ii) all other LIBOR settings, including the one-week and two-month USD LIBOR settings, immediately following the LIBOR publication on Friday, December 31, 2021. There remains uncertainty regarding the nature of any replacement rate and the impact of the transition from LIBOR on the Fund’s transactions and the financial markets generally. As such, the potential effect of a transition away from LIBOR on the Fund or the Fund’s investments cannot yet be determined.

Operational Risk

The valuation of the Fund’s investments may be negatively impacted because of the operational risks arising from factors such as processing errors and human errors, inadequate or failed internal or external processes, failures in systems and technology, changes in personnel, and errors caused by third party service providers or trading counterparties. It is not possible to identify all of the operational risks that may affect the Fund or to develop processes and controls that completely eliminate or mitigate the occurrence of such failures. The Fund and its shareholders could be negatively impacted as a result.

Cybersecurity Risk

With the increased use of technologies such as mobile devices and Web-based or “cloud” applications, and the dependence on the Internet and computer systems to conduct business, the Fund is susceptible to operational, information security and related risks. In general, cybersecurity incidents can result from deliberate attacks or unintentional events (arising from external or internal sources) that may cause the Fund to lose proprietary information, suffer data corruption, physical damage to a computer or network system or lose operational capacity. Cybersecurity attacks include, but are not limited to, infection by malicious software, such as malware or computer viruses or gaining unauthorized access to digital systems, networks or devices that are used to service the Fund’s operations (e.g., through “hacking,” “phishing” or malicious software coding) or other means for purposes of misappropriating assets or sensitive information, corrupting data, or causing operational disruption. Cybersecurity attacks may also be carried out in a manner that does not require gaining unauthorized access, such as causing denial-of-service attacks on the Fund’s websites (i.e., efforts to make network services unavailable to intended users). In addition, authorized persons could inadvertently or intentionally release confidential or proprietary information stored on the Fund’s systems.

Cybersecurity incidents affecting the Fund’s subadviser, Western Asset, other service providers to the Fund or its shareholders (including, but not limited to, Fund accountants, custodians, sub-custodians, transfer agents and financial intermediaries) have the ability to cause disruptions and impact business operations, potentially resulting in financial losses to both the Fund and its shareholders, interference with the Fund’s ability to calculate its net asset value, impediments to trading, the inability of Fund shareholders to transact business and the Fund to process transactions, violations of applicable privacy and other laws (including the release of private shareholder information) and attendant breach notification and credit monitoring costs, regulatory fines, penalties, litigation costs, reputational damage, reimbursement or other compensation costs, forensic investigation and remediation costs, and/or additional compliance costs. Similar adverse consequences could result from cybersecurity incidents affecting issuers of securities in which the Fund invests, counterparties with which the Fund engages in transactions, governmental and other regulatory authorities, exchange and other financial market operators, banks, brokers,

39

dealers, insurance companies and other financial institutions (including financial intermediaries and other service providers) and other parties. In addition, substantial costs may be incurred in order to safeguard against and reduce the risk of any cybersecurity incidents in the future. In addition to administrative, technological and procedural safeguards, the Manager and Western Asset have established business continuity plans in the event of, and risk management systems to prevent or reduce the impact of, such cybersecurity incidents. However, there are inherent limitations in such plans and systems, including the possibility that certain risks have not been identified, as well as the rapid development of new threats. Furthermore, the Fund cannot control the cybersecurity plans and systems put in place by its service providers or any other third parties whose operations may affect the Fund and its shareholders. The Fund and its shareholders could be negatively impacted as a result.

Subadviser Philosophy

Western Asset’s high-yield portfolios are constructed using top-down economic and industry knowledge integrated with bottom-up fundamental credit research. Portfolio managers combine Western Asset’s economic assessment along with industry sector insights from its dedicated research staff to derive the general framework for portfolio construction. This framework provides the foundation for how the portfolio will be positioned with respect to risk (aggressive, neutral, conservative) as well as identifying sector overweights and underweights. Risk and weightings are formally re-visited on a monthly basis, but informally evaluated on a continual basis.

Once the general framework of the portfolio has been established, the bottom-up process provides the basis for populating the targeted industry weightings through individual credit selection.

Western Asset adheres to a rigorous sell discipline. Credits are considered for sale when they satisfy one of three objectives: the security meets or exceeds its respective relative value target, the risk associated with holding the security no longer justifies the expected return, or a material change has been made to the original investment premise that affects its fundamental valuation. In situations where a company is experiencing a perceived rapid credit deterioration (i.e., it breaks below a pre-determined price threshold), a team approach is employed to implement an immediate and comprehensive review within 24 hours. The goal of these reviews is to quickly allocate the necessary resources needed to make a timely and informed re-assessment of Western Asset’s position and determine the appropriate course of action.

Integrated Team Approach

Western Asset’s fixed income discipline emphasizes a team approach that unites groups of specialists dedicated to different market sectors. A team of investment professionals at Western Asset has daily responsibility for the management of the portfolio and for the implementation of the investment process. The investment responsibilities of each sector group are distinct, yet results are derived from the constant interaction that unites the specialty groups into a cohesive investment management team. The sector teams are comprised of Western Asset’s senior portfolio managers, research analysts, and an in-house economist who are highly skilled and experienced in all major areas of the fixed income market. They exchange views on a daily basis and meet more formally twice each month to review Western Asset’s economic outlook and investment strategy. This structure seeks to ensure that client portfolios benefit from a consensus that draws on the expertise of all team members.

Subadviser Investment Process

Western Asset’s high-yield portfolio construction process begins with Western Asset’s view regarding the global macroeconomic environment. Western Asset’s view is determined by the U.S. Broad Strategy Committee. This Committee includes Western Asset’s senior portfolio managers, the heads of the various fixed-income asset classes and senior officers of Western Asset. This Committee discusses debates and determines Western Asset’s broad market portfolio strategies while considering various inputs including central bank policies, strength of the economy, direction of interest rates and shape of the yield curve.

The Global Credit Committee (“GCC”) considers the output of the U.S. Broad Strategy Committee particularly as it relates to setting the overall risk profile for credit portfolios as well as when considering gaining non-benchmark sector exposure, if allowed by a fund’s guidelines. The members of the GCC include the heads of the various credit asset classes including U.S. high-yield, U.S. investment-grade, U.S. bank loan, emerging market credit, non-U.S. high-yield and non-U.S. investment-grade credit. The GCC meets monthly, or as needed, with the primary objectives of rating the relative value characteristics of the credit asset classes and providing guidance as to a portfolios relative risk profile.

Western Asset’s high-yield portfolio managers consider the outputs of both the U.S. Broad Strategy and GCC within the context of industry sector insights from the dedicated credit research staff to derive the general framework for portfolio construction. This framework provides the foundation for how the portfolio will be positioned with respect to risk (aggressive, neutral, conservative) as well as identifying sector overweights and underweights. Risk and weightings are formally re-visited on a monthly basis, discussed in regular weekly meetings and evaluated on a continual basis with additional ad-hoc meetings being held should market conditions require. At this point in the process, Western Asset’s credit portfolio managers, analysts, traders, portfolio analysts and risk management combine efforts in the bottom-up process that attempts to discern relative value in the market place.

Western Asset’s bottom-up process provides the basis for populating the targeted industry weightings through individual credit issuer selection. Bottom-up fundamental issuer level credit research and analysis is performed by Western Asset’s dedicated high-yield analysts, with an average of 25 years of experience. Western Asset’s credit analysts conduct onsite visits, management interviews, review financial statements, attend industry/issuer conferences (those held for the benefit of both fixed-income and equity investors), make projections and consult relevant reference material to aid in the fundamental credit research process. Western Asset’s credit analysts are located on the trading desk and are exposed to market pricing throughout the course of the day. Western Asset’s credit analysts provide relative value analysis as part of their overall fundamental review. Armed with the results of their fundamental analysis, pricing grids on each part of the capital structure for each issuer within the industry and full knowledge as to covenant features of each issue the credit analysts are positioned to make relative value recommendations that are supported by their work and presented to the credit team. The recommendations of buy/hold or sell are based on the analysts view after conducting relative value analysis on all major issuers within the industry and identifying those issuers that offer, and those that do not, compelling risk adjusted opportunities.

With the general framework determined and specific issuer opportunities identified, the credit team is ready to fund the portfolio. The portfolio managers will work with the traders and risk management in an effort to construct a portfolio that conforms to the desired strategic structure and incorporates the issuer and issue recommendations of the research analysts. Risk management is fully integrated in the investment process. Risk managers dedicated to the high-yield strategy meet with the portfolio managers regularly to formally review portfolio risk, sources of risk, concentrations, correlations and recent trading activity as well as other metrics. Risk managers and portfolio managers meet informally on a frequent basis for multiple reasons including for the purpose of reviewing scenario analysis to consider the impact on risk metrics of trades under consideration. The role of risk analytics is to provide the portfolio managers with analysis that include, but is not limited to, ex-ante tracking error, value at risk, issuer and industry concentrations versus the benchmark, duration, spread duration, stress testing and scenario analysis.

Investment Management Team

Set forth below is information regarding the team of professionals at Western Asset responsible for overseeing the day-to-day operations of the Fund. Western Asset utilizes a team approach, with decisions derived from interaction among various investment management sector specialists. The sector teams are comprised of

44

Western Asset’s senior portfolio managers, research analysts and an in-house economist. Under this team approach, management of client fixed income portfolios will reflect a consensus of interdisciplinary views.

Additional information about the portfolio managers’ compensation, other accounts managed by them and other information is provided in the SAI.

Control Persons

A control person is a person who beneficially owns more than 25% of the voting securities of a company. The Fund currently has no control person.

45

NET ASSET VALUE

The Fund determines the net asset value of its Common Stock on each day the NYSE is open for business, as of the close of the customary trading session (normally 4:00 p.m. Eastern Time), or any earlier closing time that day. The Fund determines the net asset value per share of Common Stock by dividing the value of the Fund’s securities, cash and other assets (including the value of derivatives and interest accrued but not collected) less all its liabilities (including accrued expenses, the liquidation preference of any outstanding preferred stock and dividends payable) by the total number of shares of Common Stock outstanding. Securities are valued at the mean between the last quoted bid and asked prices provided by an independent pricing service that are based on transactions in corporate obligations, quotations from corporate bond dealers, market transactions in comparable securities and various other relationships between securities. The Fund values portfolio securities for which market quotations are readily available at the last reported sales price or official closing price on the primary market or exchange on which they trade. Under the Fund’s valuation policies and procedures, which were adopted by the Board, the Fund’s short-term investments are valued at amortized cost when the security has 60 days or less to maturity. Determination of the Common Stock’s net asset value is made in accordance with U.S. generally accepted accounting principles.

The Fund values all other securities and assets at their fair value. If events occur that materially affect the value of a security between the time trading ends on the security and the close of the customary trading session of the NYSE, the Fund may value the security at its fair value as determined in good faith by or under the supervision of the Board of Directors of the Fund. The effect of using fair value pricing is that the Common Stock’s net asset value will be subject to the judgment of the Board of Directors or its designee instead of being determined by the market.

Any swap transaction that the Fund enters into may, depending on the applicable interest rate environment, have a positive or negative value for purposes of calculating net asset value. Any cap transaction that the Fund enters into may, depending on the applicable interest rate environment, have no value or a positive value. In addition, accrued payments to the Fund under such transactions will be assets of the Fund and accrued payments by the Fund will be liabilities of the Fund.

On December 3, 2020, the SEC adopted new Rule 2a-5. The new rule will establish an updated regulatory framework for registered investment company valuation practices. The Fund will not be required to comply with the new rule until September 8, 2022.

46

Unless a Common Stockholder elects to receive distributions in cash (i.e., opt out), all of such Common Stockholder’s distributions, including any capital gains distributions on Common Stock, will be automatically reinvested in additional shares of Common Stock under the Fund’s Dividend Reinvestment Plan. All distributions, prior to payment, will be authorized by the Fund’s Board of Directors. See “Dividend Reinvestment Plan.”

Unless you elect to receive distributions in cash (i.e., opt-out), all dividends, including any capital gain dividends and return of capital distributions, on your Common Stock will be automatically reinvested by Computershare Trust Company, N.A., as agent for the stockholders (the “Plan Agent”), in additional shares of Common Stock under the Fund’s Dividend Reinvestment Plan (the “Plan”). You may elect not to participate in the Plan by contacting the Plan Agent. If you do not participate, you will receive all cash distributions paid by check mailed directly to you by Computershare Trust Company, N.A., as dividend paying agent.

If you participate in the Plan, the number of shares of Common Stock you will receive will be determined as follows:

(1)    If the market price of the Common Stock (plus $0.03 per share commission) on the payment date (or, if the payment date is not a NYSE trading day, the immediately preceding trading day) is equal to or exceeds the net asset value per share of the Common Stock at the close of trading on the NYSE on the payment date, the Fund will issue new Common Stock at a price equal to the greater of

(a)    the net asset value per share at the close of trading on the NYSE on the payment date or

(b)    95% of the market price per share of the Common Stock on the payment date.

(2)    If the net asset value per share of the Common Stock exceeds the market price of the Common Stock (plus $0.03 per share commission) at the close of trading on the NYSE on the payment date, the Plan Agent will receive the dividend or distribution in cash and will buy Common Stock in the open market, on the NYSE or elsewhere, for your account as soon as practicable commencing on the trading day following the payment date and terminating no later than the earlier of (a) 30 days after the dividend or distribution payment date, or (b) the payment date for the next succeeding dividend or distribution to be made to the stockholders; except when necessary to comply with applicable provisions of the federal securities laws. If during this period: (i) the market price (plus $0.03 per share commission) rises so that it equals or exceeds the net asset value per share of the Common Stock at the close of trading on the NYSE on the payment date before the Plan Agent has completed the open market purchases or (ii) if the Plan Agent is unable to invest the full amount eligible to be reinvested in open market purchases, the Plan Agent will cease purchasing Common Stock in the open market and the Fund shall issue the remaining Common Stock at a price per share equal to the greater of (a) the net asset value per share at the close of trading on the NYSE on the day prior to the issuance of shares for reinvestment or (b)95% of the then current market price per share.

Common Stock in your account will be held by the Plan Agent in non-certificated form. Any proxy you receive will include all shares of Common Stock you have received under the Plan.

You may withdraw from the Plan (i.e., opt-out) by notifying the Plan Agent in writing at 462 South 4th Street, Suite 1600, Louisville, KY 40202 or by calling the Plan Agent at 1-888-888-0151. Such withdrawal will be effective immediately if notice is received by the Plan Agent not less than ten business days prior to any dividend or distribution record date; otherwise such withdrawal will be effective as soon as practicable after the Plan Agent’s investment of the most recently declared dividend or distribution on the Common Stock.

Plan participants who sell their shares will be charged a service charge (currently $5.00 per transaction) and the Plan Agent is authorized to deduct brokerage charges actually incurred from the proceeds (currently $0.05 per share commission). There is no service charge for reinvestment of your dividends or distributions in Common Stock. However, all participants will pay a pro rata share of brokerage commissions incurred by the Plan Agent when it makes open market purchases. Because all dividends and distributions will be automatically reinvested in additional shares of Common Stock, this allows you to add to your investment through dollar cost averaging, which may lower the average cost of your Common Stock over time. Dollar cost averaging is a technique for lowering the average cost per share over time if the Fund’s net asset value declines. While dollar cost averaging has definite advantages, it cannot assure profit or protect against loss in declining markets.

48

Automatically reinvesting dividends and distributions does not mean that you do not have to pay income taxes due upon receiving dividends and distributions. Investors will be subject to income tax on amounts reinvested under the Plan.

The Fund reserves the right to amend or terminate the Plan if, in the judgment of the Board of Directors, the change is warranted. The Plan may be terminated, amended or supplemented by the Fund upon notice in writing mailed to stockholders at least 30 days prior to the record date for the payment of any dividend or distribution by the Fund for which the termination or amendment is to be effective. Upon any termination, you will be sent cash for any fractional share of Common Stock in your account. You may elect to notify the Plan Agent in advance of such termination to have the Plan Agent sell part or all of your Common Stock on your behalf. Additional information about the Plan and your account may be obtained from the Plan Agent at 462 South 4th Street, Suite 1600, Louisville, KY 40202 or by calling the Plan Agent at 1-888-888-0151.

DESCRIPTION OF SHARES

Common Stock

As of February 28, 2022, we had approximately 58.9 million shares of Common Stock outstanding. All Common Stock offered pursuant to this Prospectus and any related Prospectus Supplement will be, upon issuance, duly authorized, fully paid and nonassessable, and will have no pre-emptive, conversion or appraisal rights or rights to cumulative voting. All Common Stock offered pursuant to this Prospectus and any related Prospectus Supplement will be of the same class and will have identical rights, as described below.

The Charter authorizes the issuance of 100,000,000 shares of Common Stock, par value $0.001 per share. All shares of Common Stock have equal rights with respect to the payment of dividends and the distribution of assets upon liquidation. Common Stock will, when issued, be fully paid and nonassessable, and will have no preemptive or conversion rights or rights to cumulative voting.

The Fund’s Common Stock is listed on the NYSE under the trading or “ticker” symbol “HIX.” The Fund intends to hold annual meetings of stockholders so long as the Common Stock is listed on a national securities exchange and such meetings are required as a condition to such listing. The Fund must continue to meet the NYSE requirements in order for the Common Stock to remain listed. Maryland law also requires the Fund to hold annual meetings each year.

Unlike open-end funds, closed-end funds, like the Fund, do not continuously offer shares and do not provide daily redemptions. Rather, if a stockholder determines to buy additional shares of Common Stock or sell shares of Common Stock already held, the stockholder may do so by trading on the NYSE through a broker or otherwise. Shares of closed-end funds may frequently trade on an exchange at prices lower than net asset value. The market value of the Common Stock may be influenced by such factors as dividend levels (which are in turn affected by expenses), call protection, dividend stability, portfolio credit quality, net asset value, relative demand for and supply of such Common Stock in the market, general market and economic conditions, and other factors beyond the control of the Fund. The Fund cannot assure you that the Common Stock will trade at a price equal to or higher than net asset value in the future. The Fund’s Common Stock is designed primarily for long-term investors, and investors in Common Stock should not view the Fund as a vehicle for trading purposes. See “Repurchase of Fund Shares.”

Each outstanding share of Common Stock entitles the holder to one vote on all matters submitted to a vote of Common Stockholders, including the election of Directors. Except as provided with respect to any other class or series, the Common Stockholders will possess the exclusive voting power. Each director shall be elected by a majority of the votes entitled to be cast in the election of directors. There is no cumulative voting in the election of Directors, which means that the holders of a majority of the outstanding shares of Common Stock can elect all of the Directors then standing for election, and the holders of the remaining shares of Common Stock will not be able to elect any Directors.

Preferred Stock

The Charter provides that the Fund’s Board of Directors may classify and issue Preferred Stock with rights as determined by the Board of Directors, by action of the Board of Directors without the approval of the Common Stockholders. We do not currently have any authorized shares of Preferred Stock. Common Stockholders have no preemptive right to purchase any Preferred Stock that might be issued.

The Fund may elect to issue Preferred Stock as part of its leverage strategy. The Fund currently expects to issue leverage, which may include Preferred Stock, representing up to 33 ¹/₃% of the Fund’s total net assets immediately after the leverage is issued. The Board of Directors also reserves the right to authorize the Fund to issue Preferred Stock to the extent permitted by the 1940 Act, which currently limits the aggregate liquidation preference of all outstanding Preferred Stock plus the principal amount of any outstanding leverage consisting of debt to 50% of the value of the Fund’s total assets less liabilities and indebtedness of the Fund (other than leverage consisting of Preferred Stock). However, under current conditions it is unlikely that the Fund will issue Preferred Stock. Although the terms of any Preferred Stock, including dividend rate, liquidation preference and redemption

50

provisions, will be set forth in articles supplementary classifying and designating such Preferred Stock, the Fund believes that it is likely that the liquidation preference, voting rights and redemption provisions of the Preferred Stock may be similar to those stated below.

Liquidation Preference

In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Fund, the holders of Preferred Stock will be entitled to receive a preferential liquidating distribution, which is expected to equal the original purchase price per share of Preferred Stock plus accrued and unpaid dividends, whether or not declared, before any distribution of assets is made to Common Stockholders. After payment of the full amount of the liquidating distribution to which they are entitled, the holders of Preferred Stock will not be entitled to any further participation in any distribution of assets by the Fund.

Voting Rights

The 1940 Act requires that the holders of any Preferred Stock, voting separately as a single class, have the right to elect at least two directors at all times. The remaining directors will be elected by holders of Common Stock and Preferred Stock, voting together as a single class. In addition, subject to the prior rights, if any, of the holders of any other class of senior securities outstanding, the holders of any Preferred Stock have the right to elect a majority of the directors of the Fund if at any time two years of dividends on any Preferred Stock are unpaid. The 1940 Act also requires that, in addition to any approval by the stockholders that might otherwise be required, the approval of the holders of a majority of any outstanding Preferred Stock, voting separately as a class, would be required to: (i) adopt any plan of reorganization that would adversely affect the Preferred Stock and (ii) take any action requiring a vote of security holders under Section 13(a) of the 1940 Act, including, among other things, changes in the Fund’s subclassification as a closed-end investment company or changes in its fundamental investment restrictions. See “Certain Provisions in the Charter and Bylaws.” As a result of these voting rights, the Fund’s ability to take any such actions may be impeded to the extent that there are any shares of Preferred Stock outstanding. Except as otherwise indicated in this prospectus and except as otherwise required by applicable law or the Charter, holders of Preferred Stock will have equal voting rights with Common Stockholders (one vote per share, unless otherwise required by the 1940 Act) and will vote together with Common Stockholders as a single class.

The affirmative vote of the holders of a majority of the outstanding Preferred Stock, voting as a separate class, will be required to amend, alter or repeal any of the preferences, rights or powers of holders of Preferred Stock so as to affect materially and adversely such preferences, rights or powers, or to increase or decrease the authorized number of shares of Preferred Stock. The class vote of holders of Preferred Stock described above will in each case be in addition to any other vote required to authorize the action in question.

Redemption, Purchase and Sale of Preferred Stock by the Fund

The terms of any Preferred Stock issued are expected to provide that: (i) they are redeemable by the Fund in whole or in part at the original purchase price per share plus accrued dividends per share; (ii) the Fund may tender for or purchase Preferred Stock; and (iii) the Fund may subsequently resell any shares so tendered for or purchased. Any redemption or purchase of Preferred Stock by the Fund will reduce any leverage applicable to the Common Stock, while any resale of shares by the Fund will increase that leverage.

The discussion above describes the possible offering of Preferred Stock by the Fund. If the Board of Directors determines to proceed with such an offering, the terms of the Preferred Stock may be the same as, or different from, the terms described above, subject to applicable law and the Fund’s Charter. The Board of Directors, without the approval of the Common Stockholders, may authorize an offering of Preferred Stock or may determine not to authorize such an offering, and may fix the terms of the Preferred Stock to be offered.

CERTAIN PROVISIONS IN THE CHARTER AND BYLAWS

The Fund has provisions in its Charter and Bylaws that could have the effect of limiting the ability of other entities or persons to acquire control of the Fund, to cause it to engage in certain transactions or to modify its structure. These provisions could have the effect of depriving stockholders of opportunities to sell their Common Stock at a premium over the then-current market price of the Common Stock. At the Fund’s first annual meeting of stockholders, the Board of Directors was divided into three classes, having initial terms ending at the first, second and third annual meeting of stockholders thereafter, respectively. Thus, at each annual meeting of stockholders, the term of one class will expire and Directors will be elected to serve in that class for terms ending at the third annual meeting of stockholders following their election. This provision could delay for up to two years the replacement of a majority of the Board of Directors. A Director may be removed from office only for cause and then only by a vote of the holders of at least 75% of the votes entitled to be cast for the election of Directors.

The Bylaws provide that with respect to any annual or special meeting of the stockholders, only such business shall be conducted as shall have been properly brought before the meeting. To be properly brought before an annual meeting, the business must be pursuant to the Fund’s notice of meeting, by or at the direction of the Board of Directors or properly brought by a stockholder who was a stockholder of record at the record date set by the Board of Directors for the purpose of determining stockholders entitled to vote at the annual meeting, at the time of giving of notice by the stockholder as provided in the Bylaws and at the time of the annual meeting (and any postponement or adjournment thereof), who is entitled to vote at the meeting and who complied with the advance notice procedures of the Bylaws. To be properly brought before a special meeting, the business must be pursuant to the Fund’s notice of meeting. Nominations of individuals for election to the Board of Directors may be properly brought before a special meeting of stockholders by or at the direction of the Board of Directors or, if the special meeting has been called in accordance with the Bylaws for the purpose of electing directors, properly brought by a stockholder who was a stockholder of record at the record date set by the Board of Directors for the purpose of determining stockholders entitled to vote at the special meeting, at the time of giving of notice by the stockholder as provided in the Bylaws and at the time of the special meeting (and any postponement or adjournment thereof), who is entitled to vote at the meeting and who complied with the advance notice procedures of the Bylaws.

The affirmative vote of at least 75% of the entire Board of Directors is required to authorize the conversion of the Fund from a closed-end to an open-end investment company, or any Charter amendments related thereto. Such conversion or amendment also requires the affirmative vote of the holders of at least 75% of the votes entitled to be cast thereon by the stockholders of the Fund unless it is approved by a vote of at least 75% of the Continuing Directors (as defined below), in which event such conversion requires the approval of the holders of a majority of the votes entitled to be cast thereon by the stockholders of the Fund. A “Continuing Director” is any member of the Board of Directors of the Fund who (i) is not a person or affiliate of a person, other than an investment company advised by the Manager or any of its affiliates, who enters or proposes to enter into a Business Combination (as defined below) with the Fund (an “Interested Party”) and (ii) who has been a member of the Board of Directors of the Fund for a period of at least 12 months, or has been a member of the Board of Directors since April 24, 1998, or is a successor of a Continuing Director who is unaffiliated with an Interested Party and is recommended to succeed a Continuing Director by a majority of the Continuing Directors then on the Board of Directors of the Fund. To amend the Charter to change any of the provisions of the first paragraph under this heading, or this paragraph, the Charter requires the affirmative vote of at least 75% of the entire Board of Directors and at least 75% of the votes entitled to be cast by stockholders.

The affirmative votes of at least 75% of the entire Board of Directors and the holders of at least (i) 80% of the votes entitled to be cast thereon by the stockholders of the Fund and (ii) in the case of a Business Combination, 66 ²/₃% of the votes entitled to be cast thereon by the stockholders of the Fund other than votes held by an Interested Party who is (or whose affiliate is) a party to a Business Combination (as defined below) or an affiliate or associate of the Interested Party, are required to authorize any of the following transactions:

(i) a merger, consolidation or statutory share exchange of the Fund with or into any other person;

(ii) an issuance or transfer by the Fund (in one or a series of transactions in any 12-month period) of any securities of the Fund to any person or entity for cash, securities or other property (or combination thereof) having an aggregate fair market value of $1,000,000 or more, excluding issuances or transfers of

52

debt securities of the Fund, sales of securities of the Fund in connection with a public offering, issuances of securities of the Fund pursuant to a dividend reinvestment plan adopted by the Fund, issuances of securities of the Fund upon the exercise of any stock subscription rights distributed by the Fund and portfolio transactions effected by the Fund in the ordinary course of business;

(iii) the sale, lease, exchange, mortgage, pledge, transfer or other disposition by the Fund (in one or a series of transactions in any 12-month period) to or with any person or entity of any assets of the Fund having an aggregate fair market value of $1,000,000 or more except for portfolio transactions (including pledges of portfolio securities in connection with borrowings) effected by the Fund in the ordinary course of its business (transactions within clauses (i), (ii) and (iii) above being known individually as a “Business Combination”);

(iv) the voluntary liquidation or dissolution of the Fund or an amendment to the Charter to terminate the Fund’s existence; or

(v) unless the 1940 Act or federal law requires a lesser vote, any stockholder proposal as to specific investment decisions made or to be made with respect to the Fund’s assets as to which stockholder approval is required under federal or Maryland law.

However, the stockholder vote described above will not be required with respect to the foregoing transactions (other than those set forth in (v) above) if they are approved by a vote of at least 75% of the Continuing Directors. In that case, if Maryland law requires stockholder approval, the affirmative vote of a majority of votes entitled to be cast thereon shall be required.

The Charter and Bylaws contain provisions the effect of which is to prevent matters, including nominations of Directors, from being considered at an annual meeting of stockholders where the Fund has not received notice of the matters generally at least 120 but no more than 150 days prior to the first anniversary of the date of the proxy statement for the preceding year’s annual meeting.

Maryland law permits a Maryland corporation to include in its charter a provision eliminating the liability of its directors and officers to the corporation and its stockholders for money damages except for liability resulting from actual receipt of an improper benefit or profit in money, property or services or active and deliberate dishonesty that is established by a final judgment and is material to the cause of action. The Charter contains such a provision that eliminates such liability to the maximum extent permitted by Maryland law. In addition, the Fund has provisions in its Charter and Bylaws that authorize the Fund, to the maximum extent permitted by Maryland law, to indemnify any present or former Director or officer from and against any claim or liability to which that person may become subject or which that person may incur by reason of his or her status as a present or former Director or officer of the Fund and to pay or reimburse their reasonable expenses in advance of final disposition of a proceeding. Pursuant to the Bylaws, absent a court determination that an officer or Director seeking indemnification was not liable on the merits or guilty of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his office, the decision by the Fund to indemnify such person will be based upon the reasonable determination of independent counsel or nonparty Independent Directors, after review of the facts, that such officer or Director is not guilty of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his office.

Reference is made to the Charter and Bylaws of the Fund, on file with the SEC, for the full text of these provisions. These provisions could have the effect of depriving stockholders of an opportunity to sell their Common Stock at a premium over prevailing market prices by discouraging a third party from seeking to obtain control of the Fund in a tender offer or similar transaction. These provisions, however, offer several possible advantages. They may require persons seeking control of the Fund to negotiate with its management regarding the price to be paid for the Common Stock required to obtain such control, they promote continuity and stability and they enhance the Fund’s ability to pursue long-term strategies that are consistent with its investment objectives.

53

Maryland Business Combination Act

The Maryland Business Combination Act will not be applicable to the Fund as a registered closed-end investment company unless and until its Board of Directors adopts a resolution to be subject to the statute, provided that the resolution will not be effective with respect to a “business combination” with any person who has become an interested stockholder before the time that the resolution is adopted. Under the Maryland Business Combination Act, “business combinations” between a Maryland corporation and an interested stockholder or an affiliate of an interested stockholder are prohibited for five years after the most recent date on which the interested stockholder becomes an interested stockholder. These business combinations include a merger, consolidation, share exchange, or, in circumstances specified in the statute, an asset transfer or issuance or reclassification of equity securities. An interested stockholder is defined as:

A person is not an interested stockholder under the statute if the board of directors approved in advance the transaction by which he otherwise would have become an interested stockholder.

After the five-year prohibition, any business combination between the Maryland corporation and an interested stockholder generally must be recommended by the board of directors of the corporation and approved by the affirmative vote of at least:

These super-majority vote requirements do not apply if the corporation’s Common Stockholders receive a minimum price, as defined under Maryland law, for their shares in the form of cash or other consideration in the same form as previously paid by the interested stockholder for its shares. The statute permits various exemptions from its provisions, including business combinations that are exempted by the board of directors prior to the time that the interested stockholder becomes an interested stockholder.

The Maryland Business Combination Act may discourage others from trying to acquire control of the Fund and increase the difficulty of consummating any offer.

Maryland Control Share Acquisition Act

The Fund has elected, by resolution unanimously adopted by the Board of Directors of the Fund, to be subject to the MCSAA. The MCSAA provides that a holder of control shares of a Maryland corporation acquired in a control share acquisition will not be entitled to vote its control shares except to the extent approved by a vote of two-thirds of the votes entitled to be cast on the matter (i.e., entitled to vote on the restoration of voting rights for the holder of the control shares). Shares owned by the acquiror, by officers or by directors who are employees of the corporation are excluded from shares entitled to vote on the matter. Control shares are voting shares of stock which, if aggregated with all other shares of stock owned by the acquiror or in respect of which the acquiror is able to exercise or direct the exercise of voting power (except solely by virtue of a revocable proxy), would entitle the acquiror to exercise voting power in electing directors within one of the following ranges of voting power:

54

Control shares do not include shares the acquiring person is then entitled to vote as a result of having previously obtained stockholder approval as described above. A control share acquisition means the acquisition of control shares, subject to certain exceptions.

A person who has made or proposes to make a control share acquisition may compel the board of directors of the corporation to call a special meeting of stockholders to be held within 50 days of demand to consider the voting rights of the holder of control shares. The right to compel the calling of a special meeting is subject to the satisfaction of certain conditions, including an undertaking to pay the expenses of the meeting. If no request for a meeting is made, the corporation may itself present the question at any stockholders meeting.

If voting rights for the holder of control shares are not approved at the meeting or if the acquiring person does not deliver an acquiring person statement as required by the statute, then the corporation may redeem for fair value any or all of the control shares, except those for which voting rights have previously been approved, subject to compliance with the 1940 Act. The right of the corporation to redeem control shares is subject to certain conditions and limitations. Fair value is determined, without regard to the absence of voting rights for the holder of control shares, as of the date of the last control share acquisition by the acquiror or, if a meeting of stockholders at which the voting rights of the shares are considered and not approved is held, as of the date of such meeting. If voting rights for the holder of control shares are approved at a stockholders meeting and the acquiror becomes entitled to vote a majority of the shares entitled to vote, all other stockholders may exercise appraisal rights. The fair value of the shares as determined for purposes of appraisal rights may not be less than the highest price per share paid by the acquiror in the control share acquisition.

The MCSAA does not apply (a) to shares acquired in a merger, consolidation or share exchange if the Fund is a party to the transaction, (b) to shares acquired under the satisfaction of a pledge or other security interest created in good faith and not for the purpose of circumventing the MCSAA, or (c) to acquisitions of shares approved or exempted by a provision contained in the Charter or Bylaws of the Fund and adopted at any time before the acquisition of the shares. Shareholders (together with any “associated persons” (as defined in the MCSAA)) that own less than ten percent of the shares entitled to vote in the election of directors are not affected by the restrictions under the MCSAA. In addition, the Bylaws provide that the MCSAA will not apply to any acquisition or proposed acquisition of shares of the Fund by any company that, in accordance with the 1940 Act or SEC exemptive order or other regulatory relief or guidance, votes the shares held by it in the same proportion as the vote of all other holders of such security or all securities.

The MCSAA is designed to discourage others from trying to acquire control of the Fund for short-term objectives, including by converting the Fund to open-end status or changing the composition of the Board, that may be detrimental to the Fund’s ability to achieve its primary investment objective of providing current income. Such provisions may limit the ability of stockholders to sell their shares at a premium over prevailing market prices by discouraging a third party from seeking to obtain control of the Fund. There can be no assurance, however, that such provisions will be sufficient to deter activist investors that seek to cause the Fund to take actions that may not be aligned with the interests of long-term stockholders.

55

REPURCHASE OF FUND SHARES

The Fund is a closed-end investment company, and as such the Common Stockholders do not have the right to cause the Fund to redeem their Common Stock. Instead, liquidity will be provided through trading in the open market. Notice is hereby given in accordance with Section 23(c) of the 1940 Act that the Fund may purchase at market prices from time to time shares of its Common Stock in the open market but is under no obligation to do so.

On November 16, 2015, the Fund announced that its Board of Directors had authorized the Fund to repurchase in the open market up to approximately 10% of the Fund’s outstanding Common Stock when the Fund’s shares are trading at a discount to net asset value. The Board has directed management of the Fund to repurchase shares of Common Stock at such times and in such amounts as management reasonably believes may enhance stockholder value. The Fund is under no obligation to purchase shares at any specific discount levels or in any specific amounts. During the year ended December 31, 2021, the Fund did not repurchase any shares.

56

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The discussion below and certain disclosure in the SAI provide general tax information related to an investment in the Fund’s Common Stock. Because tax laws are complex and often change, shareholders should consult their tax advisors about the tax consequences of an investment in the Common Stock. Unless otherwise noted, the following tax discussion applies only to U.S. shareholders that hold the Common Stock as capital assets. A U.S. shareholder is a Common Stockholder who is, for U.S. federal income tax purposes, (i) an individual who is a citizen or resident of the United States, (ii) a U.S. corporation, (iii) a trust if it (a) is subject to the primary supervision of a court in the United States and one or more U.S. persons have the authority to control all substantial decisions of the trust or (b) has made a valid election to be treated as a U.S. person, or (iv) any estate the income of which is subject to U.S. federal income tax regardless of its source.

The Fund has elected to be treated, and intends to qualify each taxable year, as a regulated investment company (a “RIC”) under Subchapter M of the Code. To qualify under Subchapter M for the favorable tax treatment accorded to RICs, the Fund must, among other things: (1) distribute to its shareholders in each taxable year at least 90% of the sum of its investment company taxable income (as that term is defined in the Code, but without regard to the deduction for dividends paid) and its net tax-exempt income; (2) derive in each taxable year at least 90% of its gross income from (a) dividends, interest, payments with respect to certain securities loans, and gains from the sale or other disposition of stock, securities or foreign currencies, or other income (including but not limited to gains from options, futures or forward contracts) derived with respect to its business of investing in such stock, securities or currencies; and (b) net income derived from interests in certain publicly traded partnerships that are treated as partnerships for U.S. federal income tax purposes and that derive less than 90% of their gross income from the items described in (a) above (each a “Qualified Publicly Traded Partnership”); and (3) diversify its holdings so that, at the end of each quarter of each taxable year of the Fund (a) at least 50% of the value of the Fund’s total assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other RICs and other securities, with such other securities limited, with respect to any one issuer, to an amount not greater in value than 5% of the value of the Fund’s total assets, and to not more than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of the Fund’s total assets is represented by the securities (other than U.S. government securities or the securities of other RICs) of (I) any one issuer, (II) any two or more issuers that the Fund controls and that are determined to be engaged in the same or similar trades or businesses or related trades or businesses, or (III) any one or more Qualified Publicly Traded Partnerships. As a RIC, the Fund generally will not be subject to U.S. federal income tax on its investment company taxable income 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. The Fund intends to distribute to its shareholders, at least annually, substantially all of its investment company taxable income and net capital gain.

If the Fund fails to satisfy as of the close of any quarter the asset diversification test referred to in the preceding paragraph, it will have 30 days to cure the failure by, for example, selling securities that are the source of the violation. Other cure provisions are available in the Code for a failure to satisfy the asset diversification test, but any such cure provision may involve the payment of a penalty excise tax.

If the Fund failed to qualify for the favorable tax treatment accorded to RICs in any taxable year, the Fund would be subject to U.S. federal income tax at regular corporate rates on its taxable income (including distributions of net capital gain), even if such income were distributed to its shareholders, and all distributions out of earnings and profits would be taxed to shareholders as ordinary dividend income. Such distributions generally would be eligible (i) to be treated as “qualified dividend income” in the case of individual and other noncorporate shareholders and (ii) for the dividends received deduction in the case of corporate shareholders. To qualify again to be taxed as a RIC in a subsequent year, the Fund would be required to distribute to its Common Stockholders its earnings and profits attributable to non-RIC years reduced by an interest charge on 50% of such earnings and profits payable by the Fund to the Internal Revenue Service (the “IRS”). In addition, if the Fund failed to qualify as a RIC for a period greater than two taxable years, then the Fund would be required to elect to recognize and pay tax on any net built-in gain (the excess of aggregate gain, including items of income, over aggregate loss that would have been realized if the Fund had been liquidated) or, alternatively, be subject to taxation on such built-in gain recognized for a period of 5 years, in order to qualify as a RIC in a subsequent year.

57

A RIC that fails to distribute, by the close of each calendar year, an amount at least equal to the sum of 98% of its ordinary taxable income for such calendar year and 98.2% of its capital gain net income (adjusted for certain ordinary losses) for the one-year period ending on October 31 of such calendar year, plus any shortfalls from any prior year’s required distribution, is liable for a 4% excise tax on the portion of the undistributed amounts of such income that are less than the required distributions. For these purposes, the Fund will be deemed to have distributed any income or gain on which it paid U.S. federal income tax.

Distributions to Common Stockholders by the Fund of ordinary income (including “market discount” realized by the Fund on the sale of debt securities), and of net short-term capital gains, if any, realized by the Fund will generally be taxable to Common Stockholders as ordinary income to the extent such distributions are paid out of the Fund’s current or accumulated earnings and profits. Distributions, if any, of net capital gains properly reported as “capital gain dividends” will be taxable as long-term capital gains, regardless of the length of time the Common Stockholder has owned Common Stock. A distribution of an amount in excess of the Fund’s current and accumulated earnings and profits (as determined for U.S. federal income tax purposes) will be treated by a Common Stockholder as a return of capital which will be applied against and reduce the Common Stockholder’s basis in his or her Common Stock. To the extent that the amount of any such distribution exceeds the Common Stockholder’s basis in his or her Common Stock, the excess will be treated by the Common Stockholder as gain from a sale or exchange of the Common Stock. Distributions paid by the Fund generally will not be eligible for the dividends received deduction allowed to corporations or for the reduced rates applicable to certain qualified dividend income received by non-corporate Common Stockholders.

A distribution by the Fund consisting of a return of capital should not be considered a dividend yield or total return of an investment in the Fund’s Common Stock. Common Stockholders who receive the payment of a distribution consisting of a return of capital may be under the impression that they are receiving net profits when they are not. Stockholders should not assume that the source of a distribution from the Fund is net profits.

Distributions will be treated in the manner described above regardless of whether such distributions are paid in cash or invested in additional Common Stock pursuant to the Dividend Reinvestment Plan. Common Stockholders receiving distributions in the form of additional Common Stock will be treated as receiving a distribution in the amount of cash that they would have received if they had elected to receive the distribution in cash, unless the Fund issues additional Common Stock with a fair market value equal to or greater than net asset value, in which case such Common Stockholders will be treated as receiving a distribution in the amount of the fair market value of the distributed Common Stock. The additional Common Stock received by a Common Stockholder pursuant to the Dividend Reinvestment Plan will have a new holding period commencing on the day following the day on which the Common Stock is credited to the Common Stockholder’s account.

Although dividends generally will be treated as distributed when paid, dividends declared in October, November or December, payable to shareholders of record on a specified date in one of those months, and paid during the following January, will be treated as having been distributed by the Fund (and received by shareholders) on December 31 of the year in which declared.

The Fund may elect to retain its net capital gain or a portion thereof for investment and be taxed at corporate rates on the amount retained. In such case, the Fund may designate the retained amount as undistributed capital gains in a written notice to its shareholders, who will be treated as if each received a distribution of his pro rata share of such gain, with the result that each Common Stockholder will (i) be required to report its pro rata share of such gain on its tax return as long-term capital gain, (ii) receive a refundable tax credit for its pro rata share of tax paid by the Fund on the gain and (iii) increase the tax basis for its Common Stock by an amount equal to the deemed distribution less the tax credit.

In general, the sale, exchange or other disposition of Common Stock will result in capital gain or loss to Common Stockholders. A Common Stockholder’s gain or loss generally will be a long-term capital gain or loss if the Common Stock has been held for more than one year. Present law taxes both long- and short-term capital gains of corporations at the rates applicable to ordinary income. For non-corporate taxpayers, however, long-term capital gains are currently eligible for reduced rates of taxation. Losses realized by a holder on the sale, exchange or other disposition of Common Stock held for six months or less are treated as long-term capital losses to the extent of any distribution of long-term capital gain received (or amounts designated as undistributed capital gains) with respect to

58

such Common Stock. In addition, no loss will be allowed on the sale, exchange or other disposition of Common Stock if the Common Stockholder acquires (including pursuant to the Dividend Reinvestment Plan) or enters into a contract or option to acquire securities that are substantially identical to such Common Stock within 30 days before or after the disposition. In such case, the basis of the securities acquired will be adjusted to reflect the disallowed loss.

The Fund may be required to withhold from all distributions and redemption proceeds payable to U.S. shareholders who fail to provide the Fund with their correct taxpayer identification numbers or to make required certifications, or who have been notified by the IRS that they are subject to backup withholding. Certain shareholders specified in the Code generally are exempt from such backup withholding. This backup withholding is not an additional tax. Any amounts withheld may be refunded or credited against a Common Stockholder’s U.S. federal income tax liability, provided the required information is timely furnished to the IRS.

If a shareholder is a nonresident alien individual, a foreign trust or estate or a foreign corporation, as defined for U.S. federal income tax purposes (other than such a shareholder whose ownership of Common Stock is effectively connected with a U.S. trade or business), certain dividends received by such shareholder from the Fund may be subject to U.S. federal withholding tax. To the extent that Fund distributions consist of ordinary dividends that are subject to withholding, the applicable withholding agent will generally be required to withhold U.S. federal income tax at the rate of 30% (or such lower rate as may be determined in accordance with any applicable treaty). However, dividends paid by the Fund that are “interest-related dividends” or “short-term capital gain dividends” will generally be exempt from such withholding, in each case to the extent the Fund properly reports such dividends to shareholders. For these purposes, interest-related dividends and short-term capital gain dividends generally represent distributions of interest or short-term capital gains that would not have been subject to U.S. federal withholding tax at the source if received directly by a non-U.S. shareholder, and that satisfy certain other requirements. Net capital gain dividends (that is, distributions of the excess of net long-term capital gain over net short-term capital loss) distributed by the Fund to a non-U.S. shareholder will not be subject to U.S. federal withholding tax.

The Fund may be required to withhold from distributions to non-U.S. shareholders that are otherwise exempt from U.S. federal withholding tax (or taxable at a reduced treaty rate) unless the non-U.S. shareholder certifies his or her foreign status under penalties of perjury or otherwise establishes an exemption.

Under Sections 1471 through 1474 of the Code (such Sections commonly referred to as “FATCA”), a 30% U.S. federal withholding tax may apply to any dividends that the Fund pays to (i) a “foreign financial institution” (as specifically defined in the Code), whether such foreign financial institution is the beneficial owner or an intermediary, unless such foreign financial institution agrees to verify, report and disclose its United States “account” holders (as specifically defined in the Code) and meets certain other specified requirements or (ii) a non-financial foreign entity, whether such non-financial foreign entity is the beneficial owner or an intermediary, unless such entity provides a certification that the beneficial owner of the payment does not have any substantial United States owners or provides the name, address and taxpayer identification number of each such substantial United States owner and certain other specified requirements are met. In certain cases, the relevant foreign financial institution or non-financial foreign entity may qualify for an exemption from, or be deemed to be in compliance with, these rules. In addition, foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules. You should consult your own tax advisor regarding FATCA and whether it may be relevant to your ownership of Common Stock.

The foregoing tax discussion is for general information only. The provisions of the Code and regulations thereunder presently in effect as they directly govern the taxation of the Fund and its Common Stockholders are subject to change by legislative or administrative action, and any such change may be retroactive with respect to the Fund’s transactions. The foregoing does not represent a detailed description of the U.S. federal income tax considerations relevant to special classes of taxpayers including, without limitation, financial institutions, insurance companies, investors in pass-through entities, U.S. shareholders whose “functional currency” is not the U.S. dollar, tax-exempt organizations, dealers in securities or currencies, traders in securities or commodities that elect mark to market treatment, or persons that will hold Common Stock as a position in a “straddle,” “hedge” or as part of a “constructive sale” for U.S. federal income tax purposes. In addition, this discussion does not address the application of the Medicare tax on net investment income or the U.S. federal alternative minimum tax. Shareholders are advised to consult with their own tax advisors for more detailed information concerning federal income tax matters.

PLAN OF DISTRIBUTION

We may sell our Common Stock from time to time under this Prospectus and any related Prospectus Supplement in any one or more of the following ways (1) directly to one or more purchasers, (2) through agents for the period of their appointment, (3) to underwriters as principals for resale to the public, (4) to dealers as principals for resale to the public, (5) through “at-the-market” transactions or (6) pursuant to our Dividend Reinvestment Plan.

Our securities may be sold from time to time in one or more transactions at a fixed price or fixed prices, which may change; at prevailing market prices at the time of sale; prices related to prevailing market prices; at varying prices determined at the time of sale; or at negotiated prices. Our securities may be sold other than for cash, including in exchange transactions for non-control securities, or may be sold for a combination of cash and securities. The Prospectus Supplement will describe the method of distribution of our securities offered therein.

Each Prospectus Supplement relating to an offering of our securities will state the terms of the offering, including:

Any public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time.

Direct Sales

We may sell our securities directly to, and solicit offers from, purchasers, including institutional investors or others who may be deemed to be underwriters as defined in the Securities Act for any resales of the securities. In this case, no underwriters or agents would be involved. We may use electronic media, including the internet, to sell offered securities directly. We will describe the terms of any of those sales in a Prospectus Supplement.

Distribution Through Agents

We may offer and sell our securities on a continuous basis through agents that we designate. We will name any agent involved in the offer and sale and describe any commissions payable by us in the Prospectus Supplement. Unless otherwise indicated in the Prospectus Supplement, the agents will be acting on a best efforts basis for the period of their appointment.

Offers to purchase our securities may be solicited directly by the issuer or by agents designated by the issuer from time to time. Any such agent, who may be deemed to be an underwriter as the term is defined in the Securities Act, involved in the offer or sale of the offered securities in respect of which this Prospectus is delivered will be named, and any commissions payable by the issuer to such agent set forth, in a Prospectus Supplement.

Distribution Through Underwriters

We may offer and sell our securities from time to time to one or more underwriters who would purchase the securities as principal for resale to the public either on a firm commitment or best efforts basis. If we sell our securities to underwriters, we will execute an underwriting agreement with them at the time of the sale and will

60

name them in the Prospectus Supplement. In connection with these sales, the underwriters may be deemed to have received compensation from us in the form of underwriting discounts and commissions. The underwriters also may receive commissions from purchasers of our securities for whom they may act as agent. Unless otherwise stated in the Prospectus Supplement, the underwriters will not be obligated to purchase our securities unless the conditions set forth in the underwriting agreement are satisfied, and if the underwriters purchase any of the securities, they will be required to purchase all of the offered securities. In the event of default by any underwriter, in certain circumstances, the purchase commitments may be increased among the non-defaulting underwriters or the underwriting agreement may be terminated. The underwriters may sell the offered securities to or through dealers, and those dealers may receive discounts, concessions or commissions from the underwriters as well as from the purchasers for whom they may act as agent. Sales of the offered securities by underwriters may be in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. The Prospectus Supplement will describe the method of reoffering by the underwriters. The Prospectus Supplement will also describe the discounts and commissions to be allowed or paid to the underwriters, if any, all other items constituting underwriting compensation, and the discounts and commissions to be allowed or paid to dealers, if any. If a Prospectus Supplement so indicates, we may grant the underwriters an option to purchase additional shares of our securities at the public offering price, less the underwriting discounts and commissions, within a specified number of days from the date of the Prospectus Supplement, to cover any overallotments.

Distribution Through Dealers

We may offer and sell our securities from time to time to one or more dealers who would purchase the securities as principal. The dealers then may resell the offered securities to the public at fixed or varying prices to be determined by those dealers at the time of resale. We will set forth the names of the dealers and the terms of the transaction in the Prospectus Supplement.

Distribution Through At-the-Market Offerings

We 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). An at-the-market offering may be through one or more underwriters or dealers acting as principal or agent for us.

General Information

Agents, underwriters, or dealers participating in an offering of our securities may be deemed to be underwriters, and any discounts and commissions received by them and any profit realized by them on resale of the offered securities for whom they may act as agent, may be deemed to be underwriting discounts and commissions under the Securities Act.

We may offer to sell our securities either at a fixed price or at prices that may vary, at market prices prevailing at the time of sale, at prices related to prevailing market prices, or at negotiated prices.

If indicated in the applicable Prospectus Supplement, we may authorize underwriters or other persons acting as our agents to solicit offers by certain institutions to purchase securities from us pursuant to contracts providing for payment and delivery on a future date. Institutions with which these contracts may be made include: commercial and savings banks, insurance companies, pension funds, educational and charitable institutions and others, but in all cases these institutions must be approved by us. The obligations of any purchaser under any contract will be subject only to those conditions described in the applicable Prospectus Supplement. The underwriters and the other agents will not have any responsibility for the validity or performance of the contracts. The applicable Prospectus Supplement will describe the commission payable for solicitation of those contracts.

In connection with any offering of the securities in an underwritten transaction, the underwriters may engage in transactions that stabilize, maintain, or otherwise affect the market price of the Common Stock. Those transactions may include overallotment, entering stabilizing bids, effecting syndicate covering transactions, and reclaiming selling concessions allowed to an underwriter or a dealer.

61

Any of these activities may stabilize or maintain the market price of the securities above independent market levels. The underwriters are not required to engage in these activities, and may end any of these activities at any time.

Any underwriters that are qualified market makers on the NYSE may engage in passive market making transactions in our securities on the NYSE in accordance with Regulation M under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), during the business day prior to the pricing of the offering, before the commencement of offers or sales of the common stock. Passive market makers must comply with applicable volume and price limitations and must be identified as passive market makers. In general, a passive market maker must display its bid at a price not in excess of the highest independent bid for such security; if all independent bids are lowered below the passive market maker’s bid, however, the passive market maker’s bid must then be lowered when certain purchase limits are exceeded. Passive market making may stabilize the market price of the securities at a level above that which might otherwise prevail in the open market and, if commenced, may be discontinued at any time.

We will not require underwriters or dealers to make a market in the Common Stock. Any underwriters to whom the offered securities are sold for offering and sale may make a market in the offered securities, but the underwriters will not be obligated to do so and may discontinue any market-making at any time without notice.

Under agreements entered into with us, underwriters and agents may be entitled to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, or to contribution for payments the underwriters or agents may be required to make. The underwriters, agents, and their affiliates may engage in financial or other business transactions with us and our subsidiaries, if any, in the ordinary course of business.

The aggregate offering price specified on the cover of this Prospectus relates to the offering of the securities not yet issued as of the date of this Prospectus. The place and time of delivery for the offered securities in respect of which this Prospectus is delivered are set forth in the accompanying Prospectus Supplement.

To the extent permitted under the 1940 Act and the rules and regulations promulgated thereunder, the underwriters may from time to time act as a broker or dealer and receive fees in connection with the execution of our portfolio transactions after the underwriters have ceased to be underwriters and, subject to certain restrictions, each may act as a broker while it is an underwriter.

A Prospectus and accompanying Prospectus Supplement in electronic form may be made available on the websites maintained by the underwriters. The underwriters may agree to allocate our securities for sale to their online brokerage account holders. Such allocations of our securities for internet distributions will be made on the same basis as other allocations. In addition, our securities may be sold by the underwriters to securities dealers who resell securities to online brokerage account holders.

CAUTIONARY NOTICE REGARDING FORWARD-LOOKING STATEMENTS

This Prospectus Supplement, the accompanying Prospectus and the SAI contain forward-looking statements. All statements other than statements of historical facts included in this Prospectus Supplement and the accompanying Prospectus that address activities, events or developments that we expect, believe or anticipate will or may occur in the future are forward-looking statements including, in particular, the statements about our plans, objectives, strategies and prospects regarding, among other things, our financial condition, results of operations and business. We have identified some of these forward-looking statements with words like “believe,” “may,” “could,” “might,” “forecast,” “possible,” “potential,” “project,” “will,” “should,” “expect,” “intend,” “plan,” “predict,” “anticipate,” “estimate,” “approximate” or “continue” and other words and terms of similar meaning and the negative of such terms. Such forward-looking statements may be contained in this Prospectus Supplement as well as in the accompanying Prospectus and the SAI. These forward-looking statements are based on current expectations about future events affecting us and are subject to uncertainties and factors relating to our operations and business environment, all of which are difficult to predict and many of which are beyond our control. Many factors mentioned in our discussion in this Prospectus Supplement and the accompanying Prospectus, including the risks outlined under “Risks” in the accompanying Prospectus, will be important in determining future results. In addition, several factors that could materially affect our actual results are the ability of the MBS in which we invest to achieve their objectives, the timing and amount of distributions and dividends from the MBS in which we intend to invest, the dependence of our future success on the general economy and its impact on the industries in which we invest and other factors discussed in our periodic filings with the SEC.

Although we believe that the expectations reflected in our forward-looking statements are reasonable, we do not know whether our expectations will prove correct. They can be affected by inaccurate assumptions we might make or by known or unknown risks and uncertainties. The factors identified above are believed to be important factors, but not necessarily all of the important factors, that could cause our actual results to differ materially from those expressed in any forward-looking statement. Unpredictable or unknown factors could also have material adverse effects on us. Since our actual results, performance or achievements could differ materially from those expressed in, or implied by, these forward-looking statements, we cannot give any assurance that any of the events anticipated by the forward-looking statements will occur or, if any of them do, what impact they will have on our results of operations and financial condition. All forward-looking statements included in this Prospectus Supplement, the accompanying Prospectus or the SAI are expressly qualified in their entirety by the foregoing cautionary statements. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of such documents. We do not undertake any obligation to update, amend or clarify these forward-looking statements or the risk factors contained therein, whether as a result of new information, future events or otherwise, except as may be required under the federal securities laws. The forward-looking statements in this Prospectus Supplement, the accompanying Prospectus and the SAI are excluded from the safe harbor protection provided by Section 27A of the 1933 Act.

SUMMARY OF FUND EXPENSES

The purpose of the following table and example is to help you understand all fees and expenses holders of Common Stock would bear directly or indirectly. The table below is based on the capital structure of the Fund as of                      (except as noted below), adjusted for the issuance of $     million of additional shares of Common Stock.

Example

The following example illustrates the hypothetical expenses that you would pay on a $1,000 investment in Common Stock, assuming (i) “Total Annual Expenses” of    % of net assets attributable to Common Stock (which assumes the Fund’s use of leverage in an aggregate amount equal to    % of the Fund’s Managed Assets) and (ii) a 5% annual return*:

S-5

USE OF PROCEEDS

Unless otherwise specified in a Prospectus Supplement, the Fund intends to invest the net proceeds of any offering of its securities in accordance with its investment objective and policies as stated herein. It is currently anticipated that the Fund will be able to invest substantially all of the net proceeds in accordance with its investment objective and policies within three months after the completion of any offering. Pending such investment, it is anticipated that the proceeds will be primarily invested in short-term money market instruments. The Fund may also invest in U.S. government securities.

CAPITALIZATION

The following table sets forth our capitalization (i) as of , 20[    ] and (ii) as adjusted to give effect to the issuance of the shares of common stock offered hereby. As indicated below, Common Stockholders will bear the offering costs associated with this offering.

S-6

Unless a Common Stockholder elects to receive distributions in cash (i.e., opt out), all of such Common Stockholder’s distributions, including any capital gains distributions on Common Stock, will be automatically reinvested in additional shares of Common Stock under the Fund’s Dividend Reinvestment Plan. See “Dividend Reinvestment Plan.”

MARKET AND NET ASSET VALUE INFORMATION

The Fund’s currently outstanding Common Stock is listed on the NYSE under the symbol “HIX.” Our Common Stock commenced trading on the NYSE on                  .

Our Common Stock has traded both at a premium and at a discount in relation to the Fund’s net asset value per share. Although our Common Stock has traded at a premium to net asset value, we cannot assure that this will occur after any offering or that the Common Stock will not trade at a discount in the future. Our issuance of additional Common Stock may have an adverse effect on prices in the secondary market for our Common Stock by increasing the number of shares of Common Stock available, which may create downward pressure on the market price for our Common Stock. Shares of closed-end investment companies frequently trade at a discount to net asset value. See “Risks—Market Discount from Net Asset Value Risk.”

The following table sets forth for each of the periods indicated the range of high and low closing sale price of our Common Stock and the quarter-end sale price, each as reported on the NYSE, the net asset value per share of Common Stock and the premium or discount to net asset value per share at which our shares were trading. Net asset value is generally determined on each business day that the NYSE is open for business. See “Net Asset Value” for information as to the determination of our net asset value.

Source of market prices: Bloomberg.

The Fund is a diversified, closed-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). The Fund’s primary investment objective is to maximize current income.

The Fund’s investment adviser is Legg Mason Partners Fund Advisor, LLC (the “Manager”).

The shares of Common Stock are listed on the New York Stock Exchange (“NYSE”) under the symbol “HIX”. Common Stockholders of record on                 , 2022 (the “Record Date”) will receive                  Rights for each share of Common Stock held.
