JAY GERKEN, CFA Chairman, President and Chief Executive Officer Dear Shareholder, Bond investors spent much of the six months ended April 30, 2004 dissecting language from the Federal Reserve for clues on its assessment of the U.S. economy. During this time, the economy's quarterly pace of growth continued to advance at a moderate rate that significantly exceeded levels in early 2003.(i) Even the labor market, which generated lackluster results over most of the period, grew significantly in March by some measures.(ii) On a local level, state-tax revenues remained stronger versus the first half of last year. The combination of stronger economic growth and recent comments from the Fed exacerbated bond investors' concerns about the course of interest rates. As a result the yields on municipal bonds, which move opposite to their prices, rose over the period following their sharp spike in April.(iii) However, given that the fund's manager had anticipated that the U.S. economy could begin to pick up, the manager maintained a defensive posture in managing the fund's exposure to interest rate sensitivity. Although this approach detracted from the fund's performance during times when bond prices rose, it diminished the downward pricing pressures on the portfolio when bond prices declined, such as in April. Your fund returned 1.61%, based on its New York Stock Exchange ("NYSE") market price and 2.47% based on its net asset value ("NAV")(iv) per share during the six months ended April 30. In comparison, the unmanaged Lehman Brothers Municipal Bond Index(v) returned 1.19% and its Lipper high-yield municipal debt closed-end funds category average was 3.09% over the same time frame.(vi) Please note that Lipper performance returns are based on each fund's NAV. During this six-month period, the fund distributed dividends to shareholders totaling $0.28 per share. The performance table shows the fund's 30-day SEC and annualized distribution yields as well as its six-month total return based on its NAV and market price as of April 30, 2004. Past performance is not indicative of future results. The fund's yields will vary. 1 ================================================================================ ================================== [CLIP ART] ================================== -------------------------------------------------------------------------------- FUND PERFORMANCE AS OF APRIL 30, 2004 -------------------------------------------------------------------------------- Annualized Six-Month 30-Day Distribution Total Price Per Share SEC Yield Yield Return -------------------------------------------------------------------------------- $7.83 (NAV) 6.95% 6.97% 2.47% -------------------------------------------------------------------------------- $7.50 (NYSE) 7.26% 7.28% 1.61% -------------------------------------------------------------------------------- All figures represent past performance and are not a guarantee of future results. The fund's yields will vary. Total returns are based on changes in NAV or market price, respectively. Total returns assume the reinvestment of all dividends and/or capital gains distributions, if any, in additional shares. Annualized distribution yield is the fund's current monthly income dividend rate, annualized, and then divided by the NAV or the market price noted in this report. The annualized distribution yield assumes a current monthly income dividend rate of $0.0455 for 12 months. The "SEC yield" is a return figure often quoted by bond and other fixed income mutual funds. This quotation is based on the most recent 30-day (or one month) period covered by the fund's filings with the SEC. The yield figure reflects the dividends and interest earned during the period after deduction of the fund's expenses for the period. These yields are as of April 30, 2004 and are subject to change. -------------------------------------------------------------------------------- Information About Your Fund In recent months several issues in the mutual fund industry have come under the scrutiny of federal and state regulators. The fund's Adviser and some of its affiliates have received requests for information from various government regulators regarding market timing, late trading, fees and other mutual fund issues in connection with various investigations. The fund has been informed that the Adviser and its affiliates are responding to those information requests, but are not in a position to predict the outcome of these requests and investigations. Looking for Additional Information? The fund is traded under the symbol "MHF" and its closing market price is available in most newspapers under the NYSE listings. The daily NAV is available online under symbol XMHFX. Barron's and The Wall Street Journal's Monday editions carry closed-end fund tables that will provide additional information. In addition, the fund issues a quarterly press release that can be found on most major financial web sites as well as www.citigroupassetmanagement.com. In a continuing effort to provide information concerning the fund, shareholders may call 1-888-735-6507, Monday through Friday from 8:00 a.m. to 6:00 p.m. Eastern Time, for the fund's current net asset value, market price and other information regarding the fund's portfolio holdings and allocations. 2 ================================================================================ ================================== [CLIP ART] ================================== Thank you for your investment in the Municipal High Income Fund Inc. We appreciate that you have entrusted us to manage your money and value our relationship with you. Sincerely, /s/ R. Jay Gerken R. Jay Gerken, CFA Chairman, President and Chief Executive Officer May 8, 2004 The information provided is not intended to be a forecast of future events, a guarantee of future results or investment advice. Views expressed may differ from those of the firm as a whole. RISKS: The fund may use derivatives, such as options and futures, which can be illiquid, may disproportionately increase losses, and have a potentially large impact on fund performance. High yield bonds involve greater credit and liquidity risks than investment grade bonds. Certain investors may be subject to the Federal Alternative Minimum Tax (AMT), and state and local taxes may apply. Capital gains, if any, are fully taxable. All index performance reflects no deduction for fees, expenses or taxes. Please note that an investor cannot invest directly in an index. (i) Source: Based upon gross domestic product data from the Bureau of Economic Analysis (January 30, 2004). Gross domestic product is a market value of goods and services produced by labor and property in a given country. (ii) Based upon data released on April 1, 2004 from the U.S. Department of Labor. (iii) Source: Based upon data reflecting average yields on a universe of general obligation municipal bonds derived via Bloomberg LLP. (iv) NAV is a price that reflects the value of the fund's underlying portfolio plus other assets, less the fund's liabilities. However, the price at which an investor may buy or sell shares of the fund is at the fund's market price as determined by supply of and demand for the fund's common shares, which may be more or less than the fund's NAV. (v) The Lehman Brothers Municipal Bond Index is a broad measure of the municipal bond market with maturities of at least one year. (vi) Lipper, Inc. is a major independent mutual-fund tracking organization. Returns are based on the six-month period ended April 30, 2004, calculated among the 14 funds in the fund's Lipper category including the reinvestment of dividends and capital gains, if any. 3 ================================================================================ ================================== [CLIP ART] ================================== -------------------------------------------------------------------------------- Take Advantage of the Fund's Dividend Reinvestment Plan! As an investor in the Fund, you can participate in its Dividend Reinvestment Plan ("Plan"), a convenient, simple and efficient way to reinvest your dividends and capital gains, if any, in additional shares of the Fund. A more complete description of the Plan begins on page 28. Below is a short summary of how the Plan works. Plan Summary If you are a Plan participant who has not elected to receive your dividends in the form of a cash payment, then your dividend and capital gain distributions will be reinvested automatically in additional shares of the Fund. The number of shares in the Fund you will receive in lieu of a cash dividend is determined in the following manner. If the market price of the shares is equal to or higher than 98% of the net asset value ("NAV") per share on the date of valuation, you will be issued shares for the equivalent of either 98% of the most recently determined NAV per share or 95% of the market price, whichever is greater. If 98% of the NAV per share at the time of valuation is greater than the market price of the common stock, the Fund will buy shares for your account in the open market or on the New York Stock Exchange. If the Fund begins to purchase additional shares in the open market and the market price of the shares subsequently rises above 98% of the NAV before the purchases are completed, the Fund will attempt to cancel any remaining orders and issue the remaining dividend or distribution in shares at 98% of the Fund's NAV per share. In that case, the number of Fund shares you receive will be based on the weighted average of prices paid for shares purchased in the open market and the price at which the Fund issues the remaining shares. To find out more detailed information about the Plan and about how you can participate, please call PFPC Inc. at 1 (800) 331-1710. -------------------------------------------------------------------------------- 4 ================================================================================ Municipal High Income Fund Inc.

[CLIP ART] Bond Ratings (unaudited) ================================================================================ The definitions of the applicable ratings symbols are set forth below: Standard & Poor's Ratings Service ("Standard & Poor's") -- Ratings from "AA" to "CCC" may be modified by the addition of a plus (+) or a minus (-) sign to show relative standings within the major rating categories. AAA -- Bonds rated "AAA" have the highest rating assigned by Standard & Poor's. Capacity to pay interest and repay principal is extremely strong. AA -- Bonds rated "AA" have a very strong capacity to pay interest and repay principal and differ from the highest rated issue only in a small degree. A -- Bonds rated "A" have a strong capacity to pay interest and repay principal although it is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than bonds in higher rated categories. BBB -- Bonds rated "BBB" are regarded as having an adequate capacity to pay interest and repay principal. Whereas they normally exhibit adequate protection parameters, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity to pay interest and repay principal for bonds in this category than in higher rated categories. BB, B, CCC, -- Bonds rated "BB", "B", "CCC", "CC" and "C" are regarded, on CC and C balance, as predominantly speculative and with respect to capacity to pay interest and repay principal in accordance with the terms of the obligation. "BB" represents a lower degree of speculation than "B", and "C" the highest degree of speculation. While such bonds will likely have some quality and protective characteristics, these are outweighed by large uncertainties or major risk exposures to adverse conditions. D -- Bond rated "D" are in default, and payment of interest and/or repayment of principal is in arrears. Moody's Investors Service ("Moody's") -- Numerical modifiers 1, 2 and 3 may be applied to each generic rating from "Aa" to "Caa," where 1 is the highest and 3 the lowest rating within its generic category. Aaa -- Bonds rated "Aaa" are judged to be of the best quality. They carry the smallest degree of investment risk and are generally referred to as "gilt edge." Interest payments are protected by a large or by an exceptionally stable margin and principal is secure. While the various protective elements are likely to change, such changes as can be visualized are most unlikely to impair the fundamentally strong position of such issues. Aa -- Bonds rated "Aa" are judged to be of high quality by all standards. Together with the "Aaa" group they comprise what are generally known as high grade bonds. They are rated lower than the best bonds because margins of protection may not be as large in "Aaa" securities or fluctuation of protective elements may be of greater amplitude or there may be other elements present which make the long-term risks appear somewhat larger than in "Aaa" securities. A -- Bonds rated "A" possess many favorable investment attributes and are to be considered as upper medium grade obligations. Factors giving security to principal and interest are considered adequate but elements may be present which suggest a susceptibility to impairment some time in the future. 15 Municipal High Income Fund Inc. [CLIP ART] Bond Ratings (unaudited) (continued) ================================================================================ Baa -- Bonds rated "Baa" are considered as medium grade obligations, i.e., they are neither highly protected nor poorly secured. Interest payments and principal security appear adequate for the present but certain protective elements may be lacking or may be characteristically unreliable over any great length of time. Such bonds lack outstanding investment characteristics and in fact have speculative characteristics as well. Ba -- Bonds rated "Ba" are judged to have speculative elements; their future cannot be considered as well assured. Often the protection of interest and principal payments may be very moderate thereby not well safeguarded during both good and bad times over the future. Uncertainty of position characterizes bonds in this class. B -- Bonds rated "B" generally lack characteristics of desirable investments. Assurance of interest and principal payments or of maintenance of other terms of the contract over many long period of time may be small. Caa -- Bonds rated "Caa" are of poor standing. These issues may be in default, or there may be present elements of danger with respect to principal or interest. Ca -- Bonds rated "Ca" represent obligations which are speculative in a high degree. Such issues are often in default or have other marked shortcomings. C -- Bonds rated "C" are the lowest rated class of bonds, and issues so rated can be regarded as having extremely poor prospects of ever attaining any real investment standing. Fitch Ratings ("Fitch") -- Ratings from "A" to "CCC" may be modified by the addition of a plus (+) or a minus (-) sign to show relative standings with the major ratings categories. AAA -- Bonds rated "AAA" by Fitch have the lowest expectation of credit risk. The obligor has an exceptionally strong capacity for timely payment of financial commitments which is highly unlikely to be adversely affected by foreseeable events. A -- Bonds rated "A" have a low expectation of credit risk. The capacity for timely payment of financial commitments is considered strong. This capacity may, nevertheless, be more vulnerable to changes in circumstances or in economic conditions than is the case for higher ratings. BBB -- Bonds rated "BBB" currently have a low expectation of credit risk. The capacity for timely payment of financial commitments is considered to be adequate. Adverse changes in economic conditions and circumstances, however, are more likely to impair this capacity. This is the lowest investment grade category assigned by Fitch. BB -- Bonds rated "BB" carry the possibility of credit risk developing, particularly as the result of adverse economic change over time. Business or financial alternatives may, however, be available to allow financial commitments to be met. Securities rated in this category are not considered by Fitch to be investment grade. CCC, -- Bonds rated "CCC", "CC" and "C" carry the real possibility of CC and C defaulting. The capacity to meet financial commitments depends solely on a sustained, favorable business and economic environment. Default of some kind on bonds rated "CC" appears probable, a "C" rating indicates imminent default. NR -- Indicates that the bond is not rated by Standard & Poor's, Moody's or Fitch. 16 Municipal High Income Fund Inc. [CLIP ART] Short-Term Bond Ratings (unaudited) ================================================================================ A-1 -- Standard & Poor's highest commercial paper and variable-rate demand obligation (VRDO) rating indicating that the degree of safety regarding timely payment is either overwhelming or very strong; those issues determined to possess overwhelming safety characteristics are denoted with a plus (+) sign.

[CLIP ART] Notes to Financial Statements (unaudited) ================================================================================ 1. Significant Accounting Policies Municipal High Income Fund Inc. ("Fund"), a Maryland corporation, is registered under the Investment Company Act of 1940, as amended, as a diversified, closed-end management investment company. The following are significant accounting policies consistently followed by the Fund and are in conformity with generally accepted accounting principles ("GAAP"): (a) security transactions are accounted for on trade date; (b) securities are valued at the mean between the bid and asked prices provided by an independent pricing service that are based on transactions in municipal obligations, quotations from municipal bond dealers, market transactions in comparable securities and various relationships between securities; securities with no readily obtainable market quotations are valued in good faith at fair value by or under the direction of the Fund's Board of Directors; (c) securities maturing within 60 days or less are valued at cost plus accreted discount, or minus amortized premium, which approximates value; (d) gains or losses on the sale of securities are calculated by using the specific identification method; (e) interest income, adjusted for amortization of premium and accretion of discount, is recorded on an accrual basis; (f) dividends and distributions to shareholders are recorded on the ex-dividend date; (g) in accordance with Statement of Position 93-2 Determination, Disclosure, and Financial Statement Presentation of Income, Capital Gain, and Return of Capital Distributions by Investment Companies, book and tax basis differences relating to shareholder distributions and other permanent book and tax differences are reclassified to paid-in capital. In addition, the character of income and gains to be distributed is determined in accordance with income tax regulations which may differ from U.S. generally accepted accounting principles; (h) the Fund intends to comply with the applicable provisions of the Internal Revenue Code of 1986, as amended, pertaining to regulated investment companies and to make distributions of taxable income sufficient to relieve it from substantially all Federal income and excise taxes; and (i) estimates and assumptions are required to be made regarding assets, liabilities and changes in net assets resulting from operations when financial statements are prepared. Changes in the economic environment, financial markets and any other parameters used in determining these estimates could cause actual results to differ. In addition, the Fund invests in high-yield instruments that are subject to certain credit and market risks. The yields of high-yield debt obligations reflect, among other things, perceived credit risk. The Fund's investment in securities rated below investment-grade typically involve risks not associated with higher rated securities including, among others, greater risk of timely and ultimate payment of interest and principal, greater market price volatility and less liquid secondary market trading. 2. Exempt-Interest Dividends and Other Distributions The Fund intends to satisfy conditions that will enable interest from municipal securities, which is exempt from Federal income tax, to retain such tax-exempt status when distributed to the shareholders of the Fund. 21 Municipal High Income Fund Inc. [CLIP ART] Notes to Financial Statements (unaudited) (continued) ================================================================================ It is the Fund's policy to distribute dividends monthly. Capital gains distributions, if any, are taxable to shareholders, and are declared and paid at least annually. 3. Investment Advisory Agreement, Administration Agreement and Other Transactions Smith Barney Fund Management LLC ("SBFM"), an indirect wholly-owned subsidiary of Citigroup Inc. ("Citigroup"), acts as investment adviser to the Fund. The Fund pays SBFM an investment advisory fee calculated at an annual rate of 0.40% of the Fund's average daily net assets. SBFM also acts as the administrator of the Fund for which it receives a fee calculated at an annual rate of 0.20% of the Fund's average daily net assets. These fees are calculated daily and paid monthly. All officers and one Director of the Fund are employees of Citigroup or its affiliates. 4. Investments During the six months ended April 30, 2004, the aggregate cost of purchases and proceeds from sales of investments (including maturities of long-term investments, but excluding short-term investments) were as follows: Purchases ........................................................ $ 22,229,632 ============ Sales ............................................................ $ 23,341,322 ============ At April 30, 2004, the aggregate gross unrealized appreciation and depreciation of investments for Federal income tax purposes were substantially as follows: Gross unrealized appreciation ................................... $ 3,999,151 Gross unrealized depreciation ................................... (21,238,504) ------------ Net unrealized depreciation ..................................... $(17,239,353) ============ 5. Futures Contracts Securities or cash equal to the initial margin amount are either deposited with the broker or segregated by the custodian upon entering into the futures contract. Additional securities are also segregated up to the current market value of the futures contracts. During the period the futures contract is open, changes in the value of the contract are recognized as unrealized gains or losses by "marking-to-market" on a daily basis to reflect the market value of the contract at the end of each day's trading. Variation margin payments are received or made and recognized as assets due from or liabilities due to broker, depending upon whether unrealized gains or losses are incurred. When the contract is closed, the Fund records a realized gain or loss equal to the difference between the proceeds from (or cost of) the closing transactions and the Fund's basis in the contract. The Fund enters into such contracts typically to hedge a portion of its portfolio. The Fund bears the market risk that arises from changes in the value of the financial instruments and securities indices. 22 Municipal High Income Fund Inc.

Additional Information The Fund has received the following information from Citigroup Asset Management ("CAM"), the Citigroup business unit which includes the Fund's Investment Manager and other investment advisory companies, all of which are indirect, wholly-owned subsidiaries of Citigroup. CAM is reviewing its entry, through an affiliate, into the transfer agent business in the period 1997-1999. As CAM currently understands the facts, at the time CAM decided to enter the transfer agent business, CAM sub-contracted for a period of five years certain of the transfer agency services to a third party and also concluded a revenue guarantee agreement with this sub-contractor providing that the sub-contractor would guarantee certain benefits to CAM or its affiliates (the "Revenue Guarantee Agreement"). In connection with the subsequent purchase of the sub-contractor's business by an affiliate of the current sub-transfer agent (PFPC Inc.) used by CAM on many of the funds it manages, this Revenue Guarantee Agreement was amended eliminating those benefits in exchange for arrangements that included a one-time payment from the sub-contractor. The Boards of CAM-managed funds (the "Boards") were not informed of the Revenue Guarantee Agreement with the sub-contractor at the time the Boards considered and approved the transfer agent arrangements. Nor were the Boards informed of the subsequent amendment to the Revenue Guarantee Agreement when that occurred. CAM has begun to take corrective actions. CAM will pay to the applicable funds approximately $17 million (plus interest) that CAM and its affiliates received from the Revenue Guarantee Agreement and its amendment. CAM also plans an independent review to verify that the transfer agency fees charged by CAM were fairly priced as compared to competitive alternatives. CAM is instituting new procedures and making changes designed to ensure no similar arrangements are entered into in the future. 23 Municipal High Income Fund Inc. [CLIP ART] Notes to Financial Statements (unaudited) (continued) ================================================================================ CAM has briefed the SEC, the New York State Attorney General and other regulators with respect to this matter, as well as the U.S. Attorney who is investigating the matter. CAM is cooperating with governmental authorities on this matter, the ultimate outcome of which is not yet determinable. The Fund's transfer agent is PFPC Inc., which is not affiliated with CAM. 24 Municipal High Income Fund Inc.

The following table provides information concerning the matters voted upon at the Meeting: 1. Election of Directors* Nominees Votes For Votes Withheld -------- --------- -------------- Paolo M. Cucchi 17,449,641 267,412 Robert A. Frankel 17,476,121 240,932 --------- * The following Directors, representing the balance of the Board of Directors, continue to serve as Directors: Allan J. Bloostein, Dwight B. Crane, R. Jay Gerken, Paul Hardin, William R. Hutchinson and George M. Pavia. 27 Municipal High Income Fund Inc. [CLIP ART] Dividend Reinvestment Plan (unaudited) ================================================================================ The Fund's policy, which may be changed by the Fund's Board of Directors, is generally to make monthly distributions of substantially all its net investment income (i.e., income other than net realized capital gains) to the holders of the Fund's capital shares. From time to time, when the Fund makes a substantial capital gains distribution, it may do so in lieu of paying its regular monthly dividend. Net income of the Fund consists of all income accrued on portfolio assets less all expenses of the Fund. Expenses of the Fund are accrued each day. Net realized capital gains, if any, will be distributed to shareholders at least once a year. Under the Fund's Dividend Reinvestment Plan ("Plan"), a shareholder whose capital shares is registered in his or her own name will have all distributions reinvested automatically by PFPC Inc. ("PFPC"), as purchasing agent under the Plan, unless the shareholder elects to receive cash. Distributions with respect to shares registered in the name of a broker-dealer or other nominee (that is, in "street name") will be reinvested by the broker or nominee in additional shares under the Plan, unless the service is not provided by the broker or nominee or the shareholder elects to receive distributions in cash. Investors who own capital shares registered in street name should consult their broker-dealers for details regarding reinvestment. All distributions to shareholders who do not participate in the Plan will be paid by check mailed directly to the record holder by or under the direction of PFPC, as dividend-paying agent. The number of shares of capital shares distributed to participants in the Plan in lieu of a cash dividend is determined in the following manner. Whenever the market price of the common stock is equal to or exceeds 98% of net asset value ("NAV") per share on the determination date (generally, the record date for the distribution), participants will be issued shares of common stock valued at the greater of (1) 98% of the NAV or (2) 95% of the market price. To the extent that the Fund issues shares to participants in the Plan at a discount to NAV, the interests of remaining shareholders (i.e., those who do not participate in the Plan) in the Fund's net assets will be proportionately diluted. If 98% of the NAV per share of the capital shares at the time of valuation (which is the close of business on the determination date) exceeds the market price of capital shares, PFPC will buy capital shares in the open market, on the NYSE or elsewhere, for the participants' accounts. If, following the commencement of the purchases and before PFPC has completed its purchases, the market price exceeds 98% of what the NAV per share of the capital shares was at the valuation time, PFPC will attempt to terminate purchases in the open market and cause the Fund to issue the remaining portion of the dividend or distribution by issuing shares at a price equal to the greater of (1) 98% of the NAV per share as of the valuation time, or (2) 95% of the then current market price. In this case, the number of shares of capital shares received by a Plan participant will be based on the weighted average of prices paid for shares purchased in the open market and the price at which the Fund issues the remaining shares. To the extent PFPC is unable to stop open market purchases 28 Municipal High Income Fund Inc. [CLIP ART] Dividend Reinvestment Plan (unaudited) (continued) ================================================================================ and cause the Fund to issue the remaining shares, the average per share price paid by PFPC may exceed 98% of the NAV per share of the capital shares. PFPC will begin to purchase capital shares on the open market as soon as practicable after the payment date of the dividend or capital gains distribution, but in no event shall such purchases continue later than 30 days after that date, except when necessary to comply with applicable provisions of the Federal securities laws. PFPC maintains all shareholder accounts in the Plan and furnishes written confirmations of all transactions in each account, including information needed by a shareholder for personal and tax records. The automatic reinvestment of dividends and capital gains distributions will not relieve Plan participants of any income tax that may be payable on the dividends or capital gains distributions. Capital shares in the account of each Plan participant will be held by PFPC in uncertificated form in the name of the Plan participant. Plan participants are subject to no charge for reinvesting dividends and capital gains distributions under the Plan. PFPC's fees for handling the reinvestment of dividends and capital gains distributions will be paid by the Fund. No brokerage charges shall apply with respect to shares of capital shares issued directly by the Fund under the Plan. Each Plan participant will, however, bear a pro-rata share of brokerage commissions actually incurred with respect to any open market purchases made under the Plan. Experience under the Plan may indicate that changes to it are desirable. The Fund reserves the right to amend or terminate the Plan as applied to any dividend or capital gains distribution paid subsequent to written notice of the change sent to participants at least 30 days before the record date for the dividend or capital gains distribution. The Plan also may be amended or terminated by PFPC or the Fund on at least 30 days' written notice to Plan participants. All correspondence concerning the Plan should be directed by mail to PFPC Inc., P.O. Box 43027, Providence, Rhode Island 02940-3027 or by telephone at 1 (800) 331-1710. --------------------------- Notice is hereby given in accordance with Section 23(c) of the Investment Company Act of 1940, as amended, that from time to time the Fund may purchase at market prices shares of its capital shares in the open market. For the six months ended April 30, 2004, the Fund has not repurchased any shares. 29 Municipal High Income Fund Inc.

DISCLOSURE OF PROXY VOTING POLICIES AND PROCEDURES FOR CLOSED-END MANAGEMENT INVESTMENT COMPANIES. The Board of Directors of the Fund has delegated the authority to develop policies and procedures relating to proxy voting to the Manager. The Manager is part of Citigroup Asset Management ("CAM"), a group of investment adviser affiliates of Citigroup, Inc. ("Citigroup"). Along with the other investment advisers that comprise CAM, the Manager has adopted a set of proxy voting policies and procedures (the "Policies") to ensure that the Manager votes proxies relating to equity securities in the best interest of clients. In voting proxies, the Manager is guided by general fiduciary principles and seeks to act prudently and solely in the best interest of clients. The Manager attempts to consider all factors that could affect the value of the investment and will vote proxies in the manner that it believes will be consistent with efforts to maximize shareholder values. The Manager may utilize an external service provider to provide it with information and/or a recommendation with regard to proxy votes. However, such recommendations do not relieve the Manager of its responsibility for the proxy vote. In the case of a proxy issue for which there is a stated position in the Policies, CAM generally votes in accordance with such stated position. In the case of a proxy issue for which there is a list of factors set forth in the Policies that CAM considers in voting on such issue, CAM votes on a case-by-case basis in accordance with the general principles set forth above and considering such enumerated factors. In the case of a proxy issue for which there is no stated position or list of factors that CAM considers in voting on such issue, CAM votes on a case-by-case basis in accordance with the general principles set forth above. Issues for which there is a stated position set forth in the Policies or for which there is a list of factors set forth in the Policies that CAM considers in voting on such issues fall into a variety of categories, including election of directors, ratification of auditors, proxy and tender offer defenses, capital structure issues, executive and director compensation, mergers and corporate restructurings, and social and environmental issues. The stated position on an issue set forth in the Policies can always be superseded, subject to the duty to act solely in the best interest of the beneficial owners of accounts, by the investment management professionals responsible for the account whose shares are being voted. Issues applicable to a particular industry may cause CAM to abandon a policy that would have otherwise applied to issuers generally. As a result of the independent investment advisory services provided by distinct CAM business units, there may be occasions when different business units or different portfolio managers within the same business unit vote differently on the same issue. In furtherance of the Manager's goal to vote proxies in the best interest of clients, the Manager follows procedures designed to identify and address material conflicts that may arise between the Manager's interests and those of its clients before voting proxies on behalf of such clients. To seek to identify conflicts of interest, CAM periodically notifies CAM employees (including employees of the Manager) in writing that they are under an obligation (i) to be aware of the potential for conflicts of interest with respect to voting proxies on behalf of client accounts both as a result of their personal relationships and due to special circumstances that may arise during the conduct of CAM's and the Manager's business, and (ii) to bring conflicts of interest of which they become aware to the attention of compliance personnel. The Manager also maintains and considers a list of significant relationships that could present a conflict of interest for the Manager in voting proxies. The Manager is also sensitive to the fact that a significant, publicized relationship between an issuer and a non-CAM affiliate might appear to the public to influence the manner in which the Manager decides to vote a proxy with respect to such issuer. Absent special circumstances or a significant, publicized non-CAM affiliate relationship that CAM or the Manager for prudential reasons treats as a potential conflict of interest because such relationship might appear to the public to influence the manner in which the Manager decides to vote a proxy, the Manager generally takes the position that non-CAM relationships between Citigroup and an issuer (e.g. investment banking or banking) do not present a conflict of interest for the Manager in voting proxies with respect to such issuer. Such position is based on the fact that the Manager is operated as an independent business unit from other Citigroup business units as well as on the existence of information barriers between the Manager and certain other Citigroup business units. CAM maintains a Proxy Voting Committee, of which the Manager personnel are members, to review and address conflicts of interest brought to its attention by compliance personnel. A proxy issue that will be voted in accordance with a stated position on an issue or in accordance with the recommendation of an independent third party is not brought to the attention of the Proxy Voting Committee for a conflict of interest review because the Manager's position is that to the extent a conflict of interest issue exists, it is resolved by voting in accordance with a pre-determined policy or in accordance with the recommendation of an independent third party. With respect to a conflict of interest brought to its attention, the Proxy Voting Committee first determines whether such conflict of interest is material. A conflict of interest is considered material to the extent that it is determined that such conflict is likely to influence, or appear to influence, the Manager's decision-making in voting proxies. If it is determined by the Proxy Voting Committee that a conflict of interest is not material, the Manager may vote proxies notwithstanding the existence of the conflict. If it is determined by the Proxy Voting Committee that a conflict of interest is material, the Proxy Voting Committee is responsible for determining an appropriate method to resolve such conflict of interest before the proxy affected by the conflict of interest is voted. Such determination is based on the particular facts and circumstances, including the importance of the proxy issue and the nature of the conflict of interest. Methods of resolving a material conflict of interest may include, but are not limited to, disclosing the conflict to clients and obtaining their consent before voting, or suggesting to clients that they engage another party to vote the proxy on their behalf.
