Investment commentary

Economic review

The U.S. economy continued to grow over the twelve months ended October 31, 2013 (the "reporting period"), but the pace was mixed. Looking back, U.S. gross domestic product (“GDP”)ⁱ growth, as reported by the U.S. Department of Commerce, was an anemic 0.1% during the fourth quarter of 2012. This weakness was partially driven by moderating private inventory investment and federal government spending. Economic growth then accelerated, as first quarter 2013 GDP growth was 1.1%, supported by strengthening consumer spending. GDP growth in the second quarter further improved to 2.5%. This was partially due to increases in exports and non-residential fixed investments, along with a smaller decline in federal government spending versus the previous quarter. The U.S. Department of Commerce's initial reading for third quarter 2013 GDP growth, released after the reporting period ended, was 2.8%. Stronger growth was driven, in part, by a deceleration in imports and increased private inventory investment and state and local government spending.

While there was some improvement in the U.S. job market, unemployment remained elevated throughout the reporting period. When the period began, unemployment, as reported by the U.S. Department of Labor, was 7.8%. Unemployment fell to 7.7% in February 2013 and edged lower over much of the next seven months to reach 7.2% in September 2013, its lowest reading since November 2008. Unemployment then ticked up to 7.3% in October. Falling unemployment during the period was partially due to a decline in the workforce participation rate, which was 62.8% in October, the lowest level since 1978.

Meanwhile, the housing market continued to show signs of strength, as sales generally improved and home prices moved higher. According to the National Association of Realtors (“NAR”), existing-home sales dipped 3.2% on a seasonally adjusted basis in October 2013 versus the previous month, but were 6.0% higher than in October 2012. In addition, the NAR reported that the median existing-home price for all housing types was $199,500 in October 2013, up 12.8% from October 2012. This marked the eleventh consecutive month that home prices experienced a double-digit increase compared to the same period a year earlier. The inventory of homes available for sale in October 2013 was 1.8% lower than the previous month at a 5.0 month supply at the current sales pace and was 0.9% higher than in October 2012.

The manufacturing sector expanded during the majority of the reporting period, although it experienced several soft patches. Based on the Institute for Supply Management’s Purchasing Managers’ Index ("PMI")ⁱⁱ, after expanding the prior two months, the PMI fell to 49.5 in November 2012. This represented the PMI's lowest reading since July 2009 (a reading below 50 indicates a contraction, whereas a reading above 50 indicates an expansion). Manufacturing then expanded over the next five months, before contracting again in May 2013, with a PMI of 49.0. However, this was a temporary setback, as the PMI rose over the next five months and was 56.4 in October, the best reading since April 2011.

The Federal Reserve Board (“Fed”)ⁱⁱⁱ took a number of actions as it sought to meet its dual mandate of fostering maximum employment and price stability. As has been

the case since December 2008, the Fed kept the federal funds rate^iv at a historically low range between zero and 0.25%. At its meeting in December 2012, the Fed announced that it would continue purchasing $40 billion per month of agency mortgage-backed securities ("MBS"), as well as initially purchasing $45 billion per month of longer-term Treasuries. The Fed also said that it would keep the federal funds rate on hold "…as long as the unemployment rate remains above 6.5%, inflation between one and two years ahead is projected to be no more than a half percentage point above the Committee’s 2.0% longer-run goal, and longer-term inflation expectations continue to be well anchored." At its meeting that ended on June 19, 2013, the Fed did not make any material changes to its official policy statement. However, in a press conference following the meeting, Fed Chairman Bernanke said "…the Committee currently anticipates that it would be appropriate to moderate the monthly pace of purchases later this year; and if the subsequent data remain broadly aligned with our current expectations for the economy, we would continue to reduce the pace of purchases in measured steps through the first half of next year, ending purchases around midyear." In a surprise to many investors, at its meeting that ended on September 18, 2013, the Fed did not taper its asset purchase program and said that it "…decided to await more evidence that progress will be sustained before adjusting the pace of its purchases." Fed Chairman Bernanke also brought up the potential for a partial government shutdown on October 1 and the debt ceiling debate as reasons for maintaining its current policy. At the Fed's meeting that concluded on October 30, 2013, the Fed maintained its asset purchase program and said that "Asset purchases are not on a preset course, and the Committee's decisions about their pace will remain contingent on the Committee's economic outlook as well as its assessment of the likely efficacy and costs of such purchases.”

As always, thank you for your confidence in our stewardship of your assets.

Sincerely,

IV		Western Asset Municipal High Income Fund Inc.

Fund overview

Q. What is the Fund’s investment strategy?

A. The Fund seeks high current income exempt from federal income taxes. The Fund invests primarily in intermediate- and long-term municipal debt securities issued by state and local governments. However, the Fund may invest in municipal obligations of any maturity. The Fund may invest in non-publicly traded municipal securities, zero-coupon municipal obligations and non-appropriation or other municipal lease obligations.

At Western Asset Management Company (“Western Asset”), the Fund’s subadviser, we utilize a fixed-income team approach, with decisions derived from interaction among various investment management sector specialists. The sector teams are comprised of Western Asset’s senior portfolio management personnel, research analysts and an in-house economist. Under this team approach, management of client fixed-income portfolios will reflect a consensus of interdisciplinary views within the Western Asset organization. The individuals responsible for development of investment strategy, day-to-day portfolio management, oversight and coordination of the Fund are Stephen A. Walsh, Robert E. Amodeo, David T. Fare and Dennis J. McNamara. It is anticipated that Mr. Walsh will step down as a member of the Fund's portfolio management team effective on or about March 31, 2014 and that S. Kenneth Leech will join the Fund's portfolio management team at that time. Mr. Leech has been employed by Western Asset as an investment professional for more than 20 years.

Q. What were the overall market conditions during the Fund's reporting period?

A. The spread sectors (non-Treasuries) experienced several periods of heightened risk aversion and generated mixed results versus equal-durationⁱ Treasuries over the twelve months ended October 31, 2013. Risk aversion was prevalent at times given shifting economic data, geopolitical issues, signs of shifting monetary policy by the Federal Reserve Board (“Fed”)ⁱⁱand the U.S government's sixteen day partial shutdown which ended on October 16, 2013.

Both short- and long-term Treasury yields moved higher during the twelve months ended October 31, 2013. Two-year Treasury yields rose from 0.30% at the beginning of the period to 0.31% at the end of the period. Their peak of 0.52% occurred on September 5, 2013 and they were as low as 0.20% in early May 2013. Ten-year Treasury yields were 1.72% at the beginning of the period and 2.57% at the end of the period. Their peak of 2.98% also occurred on September 5, 2013 and their low of 1.58% took place in mid-November 2012.

The municipal bond market underperformed its taxable bond counterpart during the 12 months ended October 31, 2013. Over that period, the Barclays Municipal Bond Indexⁱⁱⁱ and the Barclays U.S. Aggregate Index^iv fell 1.72% and 1.08%, respectively. The municipal bond market lagged the taxable bond market during seven of the twelve months covered by this report. In addition to the negative impact of higher interest rates, investor sentiment for municipal bonds was weak at times given the negative fallout from the city of Detroit's bankruptcy filing.

Fund overview (cont’d)

Q. How did we respond to these changing market conditions?

A. There were only minor changes to the Fund during the reporting period, as we were generally comfortable with its sector, duration and yield curve^v positioning. The Fund opportunistically employed the use of short U.S. Treasury futures during the reporting period to manage duration. This strategy contributed to the Fund’s performance during the period.

Performance review

For the twelve months ended October 31, 2013, Western Asset Municipal High Income Fund Inc. returned -3.41% based on its net asset value (“NAV”)^vi and -14.91% based on its New York Stock Exchange (“NYSE”) market price per share. The Fund’s unmanaged benchmark, the Barclays Municipal Bond Index, returned -1.72% for the same period. The Lipper High Yield Municipal Debt Closed-End Funds Category Average^vii returned -3.37% over the same time frame. Please note that Lipper performance returns are based on each fund’s NAV.

Certain investors may be subject to the federal alternative minimum tax, and state and local taxes will apply. Capital gains, if any, are fully taxable. Please consult your personal tax or legal adviser.

During the twelve-month period, the Fund made distributions to shareholders totaling $0.38 per share.** The performance table shows the Fund’s twelve-month total return based on its NAV and market price as of October 31, 2013. Past performance is no guarantee of future results.

‡ Total return assumes the reinvestment of all distributions in additional shares in accordance with the Fund’s Dividend Reinvestment Plan.

Q. What were the leading contributors to performance?

A. The largest contributor to the Fund’s relative performance during the reporting period was its security selection of BB-rated and BBB-rated municipal securities. The Fund’s underweight to holdings in Puerto Rico contributed to results as Commonwealth bonds underperformed the benchmark during the reporting period. Elsewhere, an underweight to the Special Tax sector was beneficial given its underperformance versus the benchmark.

Q. What were the leading detractors from performance?

A. Although security selection in BB-rated and BBB-rated securities contributed to

relative performance, the largest detractor to performance was our overweight relative to the benchmark’s overall weighting in BB- and BBB-rated categories.

Duration and yield curve positioning were negatives for performance. The Fund’s duration was longer than that of the benchmark, which was not rewarded as rates moved higher during the reporting period. From a yield curve perspective, the Fund maintained an overweight to the 22+ year portion of the municipal yield curve. This negatively impacted performance as longer-term securities underperformed shorter-term securities.

RISKS: The Fund’s investments are subject to credit risk, inflation risk and interest rate risk. High-yield bonds involve greater credit and liquidity risks than investment grade bonds. As interest rates rise, bond prices fall, reducing the value of the Fund’s holdings. Municipal securities purchased by the Fund may be adversely affected by changes in the financial condition of municipal issuers and insurers, regulatory and political developments, uncertainties and public perceptions, and other factors. 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.

Fund overview (cont’d)

ⁱ	Duration is the measure of the price sensitivity of a fixed-income security to an interest rate change of 100 basis points. Calculation is based on the weighted average of the present values for all cash flows.

ⁱⁱ	The Federal Reserve Board (“Fed”) is responsible for the formulation of policies designed to promote economic growth, full employment, stable prices and a sustainable pattern of international trade and payments.

ⁱⁱⁱ	The Barclays Municipal Bond Index is a market value weighted index of investment grade municipal bonds with maturities of one year or more.

^iv	The Barclays U.S. Aggregate Index is a broad-based bond index comprised of government, corporate, mortgage- and asset-backed issues, rated investment grade or higher, and having at least one year to maturity.

^v	The yield curve is the graphical depiction of the relationship between the yield on bonds of the same credit quality but different maturities.

^vi

Net asset value (“NAV”) is calculated by subtracting total liabilities and outstanding preferred stock (if any) from the closing value of all securities held by the Fund (plus all other assets) and dividing the result (total investments) by the total number of the common shares outstanding. The NAV fluctuates with changes in the market prices of securities in which the Fund has invested. However, the price at which an investor may buy or sell shares of the Fund is the Fund’s market price as determined by supply of and demand for the Fund’s shares.

Spread duration measures the sensitivity to changes in spreads. The spread over Treasuries is the annual risk-premium demanded by investors to hold non-Treasury securities. Spread duration is quantified as the % change in price resulting from a 100 basis points change in spreads. For a security with positive spread duration, an increase in spreads would result in a price decline and a decline in spreads would result in a price increase.

Notes to financial statements

1. Organization and significant accounting policies

Western Asset Municipal High Income Fund Inc. (the “Fund”) was incorporated in Maryland and is registered as a diversified, closed-end management investment company under the Investment Company Act of 1940, as amended (the “1940 Act”). The Fund seeks high current income exempt from federal income taxes.

The following are significant accounting policies consistently followed by the Fund and are in conformity with U.S. generally accepted accounting principles (“GAAP”). 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. Subsequent events have been evaluated through the date the financial statements were issued.

(a) Investment valuation. The valuations for fixed income securities (which may include, but are not limited to, corporate, government, municipal, mortgage-backed, collateralized mortgage obligations and asset-backed securities) and certain derivative instruments are typically the prices supplied by independent third party pricing services, which may use market prices or broker/dealer quotations or a variety of valuation techniques and methodologies. The independent third party pricing services use inputs that are observable such as issuer details, interest rates, yield curves, prepayment speeds, credit risks/spreads, default rates and quoted prices for similar securities. Short-term fixed income securities that will mature in 60 days or less are valued at amortized cost, unless it is determined that using this method would not reflect an investment’s fair value. Futures contracts are valued daily at the settlement price established by the board of trade or exchange on which they are traded. If independent third party pricing services are unable to supply prices for a portfolio investment, or if the prices supplied are deemed by the manager to be unreliable, the market price may be determined by the manager using quotations from one or more broker/dealers or at the transaction price if the security has recently been purchased and no value has yet been obtained from a pricing service or pricing broker. When reliable prices are not readily available, such as when the value of a security has been significantly affected by events after the close of the exchange or market on which the security is principally traded, but before the Fund calculates its net asset value, the Fund values these securities as determined in accordance with procedures approved by the Fund’s Board of Directors.

The Board of Directors is responsible for the valuation process and has delegated the supervision of the daily valuation process to the Legg Mason North American Fund Valuation Committee (the “Valuation Committee”). The Valuation Committee, pursuant to the policies adopted by the Board of Directors, is responsible for making fair value determinations, evaluating the effectiveness of the Fund’s pricing policies, and reporting to the Board of Directors. When determining the reliability of third party pricing information for investments owned by the Fund, the Valuation Committee, among other things, conducts due diligence reviews of pricing vendors, monitors the daily change in prices and reviews transactions among market participants.


20		Western Asset Municipal High Income Fund Inc. 2013 Annual Report

The Valuation Committee will consider pricing methodologies it deems relevant and appropriate when making fair value determinations. Examples of possible methodologies include, but are not limited to, multiple of earnings; discount from market of a similar freely traded security; discounted cash-flow analysis; book value or a multiple thereof; risk premium/yield analysis; yield to maturity; and/or fundamental investment analysis. The Valuation Committee will also consider factors it deems relevant and appropriate in light of the facts and circumstances. Examples of possible factors include, but are not limited to, the type of security; the issuer’s financial statements; the purchase price of the security; the discount from market value of unrestricted securities of the same class at the time of purchase; analysts’ research and observations from financial institutions; information regarding any transactions or offers with respect to the security; the existence of merger proposals or tender offers affecting the security; the price and extent of public trading in similar securities of the issuer or comparable companies; and the existence of a shelf registration for restricted securities.

For each portfolio security that has been fair valued pursuant to the policies adopted by the Board of Directors, the fair value price is compared against the last available and next available market quotations. The Valuation Committee reviews the results of such back testing monthly and fair valuation occurrences are reported to the Board of Directors quarterly.

The Fund uses valuation techniques to measure fair value that are consistent with the market approach and/or income approach, depending on the type of security and the particular circumstance. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable securities. The income approach uses valuation techniques to discount estimated future cash flows to present value.

GAAP establishes a disclosure hierarchy that categorizes the inputs to valuation techniques used to value assets and liabilities at measurement date. These inputs are summarized in the three broad levels listed below:

Level 1 — quoted prices in active markets for identical investments

Level 2 — other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.)

Level 3 — significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments)

The inputs or methodologies used to value securities are not necessarily an indication of the risk associated with investing in those securities.

Notes to financial statements (cont’d)

The following is a summary of the inputs used in valuing the Fund’s assets and liabilities carried at fair value:


ASSETS
Description	Quoted Prices (Level 1)		Other Significant Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total
Municipal bonds†		—	$	157,922,616		—	$	157,922,616
Short-term investments†		—		1,400,000		—		1,400,000
Total investments		—	$	159,322,616		—	$	159,322,616

LIABILITIES
Description	Quoted Prices (Level 1)		Other Significant Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total
Other financial instruments:
Futures contracts	$	4,017		—		—	$	4,017

†	See Schedule of Investments for additional detailed categorizations.

(b) Futures contracts. The Fund uses futures contracts generally to gain exposure to, or hedge against, changes in interest rates or gain exposure to, or hedge against, changes in certain asset classes. A futures contract represents a commitment for the future purchase or sale of an asset at a specified price on a specified date.

Upon entering into a futures contract, the Fund is required to deposit cash or cash equivalents with a broker in an amount equal to a certain percentage of the contract amount. This is known as the “initial margin” and subsequent payments (“variation margin”) are made or received by the Fund each day, depending on the daily fluctuation in the value of the contract. The daily changes in contract value are recorded as unrealized gains or losses in the Statement of Operations and the Fund recognizes a realized gain or loss when the contract is closed.

Futures contracts involve, to varying degrees, risk of loss in excess of the amounts reflected in the financial statements. In addition, there is the risk that the Fund may not be able to enter into a closing transaction because of an illiquid secondary market.

(c) Credit and market risk. The Fund invests in high-yield instruments that are subject to certain credit and market risks. The yields of high-yield obligations reflect, among other things, perceived credit and market risks. The Fund’s investments in securities rated below investment grade typically involve risks not associated with higher rated securities including, among others, greater risk related to timely and ultimate payment of interest and principal, greater market price volatility and less liquid secondary market trading.

(d) Security transactions and investment income. Security transactions are accounted for on a trade date basis. Interest income, adjusted for amortization of premium and accretion of discount, is recorded on the accrual basis. The cost of investments sold is


22		Western Asset Municipal High Income Fund Inc. 2013 Annual Report

determined by use of the specific identification method. To the extent any issuer defaults or a credit event occurs that impacts the issuer, the Fund may halt any additional interest income accruals and consider the realizability of interest accrued up to the date of default or credit event.

(e) Distributions to shareholders. Distributions from net investment income of the Fund, if any, are declared quarterly and paid on a monthly basis. The Fund intends to satisfy conditions that will enable interest from municipal securities, which is exempt from federal and certain state income taxes, to retain such tax-exempt status when distributed to the shareholders of the Fund. Distributions of net realized gains, if any, are taxable and are declared at least annually. Distributions to shareholders of the Fund are recorded on the ex-dividend date and are determined in accordance with income tax regulations, which may differ from GAAP.

(f) Compensating balance arrangements. The Fund has an arrangement with its custodian bank whereby a portion of the custodian’s fees is paid indirectly by credits earned on the Fund’s cash on deposit with the bank.

(g) Federal and other taxes. It is the Fund’s policy to comply with the federal income and excise tax requirements of the Internal Revenue Code of 1986 (the “Code”), as amended, applicable to regulated investment companies. Accordingly, the Fund intends to distribute its taxable income and net realized gains, if any, to shareholders in accordance with timing requirements imposed by the Code. Therefore, no federal or state income tax provision is required in the Fund’s financial statements.

Management has analyzed the Fund’s tax positions taken on income tax returns for all open tax years and has concluded that as of October 31, 2013, no provision for income tax is required in the Fund’s financial statements. The Fund’s federal and state income and federal excise tax returns for tax years for which the applicable statutes of limitations have not expired are subject to examination by the Internal Revenue Service and state departments of revenue.

(h) Reclassification. GAAP requires that certain components of net assets be reclassified to reflect permanent differences between financial and tax reporting. These reclassifications have no effect on net assets or net asset values per share. During the current year, the following reclassifications have been made:


	Overdistributed Net Investment Income		Accumulated Net Realized Loss		Paid-in Capital
(a)		—	$	5,326,008	$	(5,326,008)
(b)	$	(16,424)		16,424		—

^(a)	Reclassifications are primarily due to the expiration of a capital loss carryfoward.

^(b)	Reclassifications are primarily due to differences between book and tax accretion of market discount on fixed income securities.

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 are registered in his or her own name will have all distributions reinvested automatically by American Stock Transfer & Trust Company (“AST”), 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 capital 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 AST, as dividend-paying agent.

The number 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 capital shares 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 capital shares 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, AST 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 AST has completed its purchases, the market price exceeds 98% of what the NAV per share of the capital shares was at the valuation time, AST 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 AST is unable to stop open market purchases and cause the Fund to issue the remaining shares, the average per share price paid by AST may exceed 98% of the NAV per share of the capital shares. AST will begin to

Dividend reinvestment plan (unaudited) (cont’d)

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.

AST 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 AST 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. AST’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 its 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 AST or the Fund on at least 30 days’ written notice to Plan participants. All correspondence concerning the Plan should be directed by mail to American Stock Transfer & Trust Company, 6201 15th Avenue, Brooklyn, New York 11219 or by telephone at 1-888-888-0151.

		All Other Fees.

		(e) Audit Committee’s pre-approval policies and procedures described in paragraph (c) (7) of Rule 2-01 of Regulation S-X.


		(1) The Charter for the Audit Committee (the “Committee”) of the Board of each registered investment company (the “Fund”) advised by LMPFA or one of their affiliates (each, an “Adviser”) requires that the Committee shall approve (a) all audit and permissible non-audit services to be provided to the Fund and (b) all permissible non-audit services to be provided by the Fund’s independent auditors to the Adviser and any Covered Service Providers if the engagement relates directly to the operations and financial reporting of the Fund. The Committee may implement policies and procedures by which such services are approved other than by the full Committee.

		The Committee shall not approve non-audit services that the Committee believes may impair the independence of the auditors. As of the date of the approval of this Audit Committee Charter, permissible non-audit services include any professional services (including tax services), that are not prohibited services as described below, provided to the Fund by the independent auditors, other than those provided to the Fund in connection with an audit or a review of the financial statements of the Fund.

ITEM 7.		DISCLOSURE OF PROXY VOTING POLICIES AND PROCEDURES FOR CLOSED-END MANAGEMENT INVESTMENT COMPANIES

Proxy Voting Guidelines and Procedures

Legg Mason Partners Fund Advisor, LLC (“LMPFA”) delegates the responsibility for voting proxies for the fund to the subadviser through its contracts with the subadviser. The subadviser will use its own proxy voting policies and procedures to vote proxies. Accordingly, LMPFA does not expect to have proxy-voting responsibility for the fund. Should LMPFA become responsible for voting proxies for any reason, such as the inability of the subadviser to provide investment advisory services, LMPFA shall utilize the proxy voting guidelines established by the most recent subadviser to vote proxies until a new subadviser is retained.

The subadviser’s Proxy Voting Policies and Procedures govern in determining how proxies relating to the fund’s portfolio securities are voted and are provided below. Information regarding how each fund voted proxies (if any) relating to portfolio securities during the most recent 12-month period ended June 30 is available without charge (1) by calling 888-777-0102, (2) on the fund’s website at http://www.lmcef.com (3) on the SEC’s website at http://www.sec.gov.

Background

Western Asset Management Company (“WA” or “Western Asset”) have adopted and implemented policies and procedures that we believe are reasonably designed to ensure that proxies are voted in the best interest of clients, in accordance with our fiduciary duties and SEC Rule 206(4)-6 under the Investment Advisers Act of 1940 (“Advisers Act”). Our authority to vote the proxies of our clients is established through investment management agreements or comparable documents, and our proxy voting guidelines have been tailored to reflect these specific contractual obligations. In addition to SEC requirements governing advisers, our proxy voting policies reflect the long-standing fiduciary standards and responsibilities for ERISA accounts. Unless a manager of ERISA assets has been expressly precluded from voting proxies, the Department of Labor has determined that the responsibility for these votes lies with the Investment Manager.

In exercising its voting authority, Western Asset will not consult or enter into agreements with officers, directors or employees of Legg Mason Inc. or any of its affiliates (except that WA may so consult and agree with each other) regarding the voting of any securities owned by its clients.

Policy

Western Asset’s proxy voting procedures are designed and implemented in a way that is reasonably expected to ensure that proxy matters are handled in the best interest of our clients. While the guidelines included in the procedures are intended to provide a benchmark for voting standards, each vote is ultimately cast on a case-by-case basis, taking into consideration Western Asset’s contractual obligations to our clients and all other relevant facts and circumstances at the time of the vote (such that these guidelines may be overridden to the extent Western Asset deems appropriate).

Procedures

Responsibility and Oversight

The Western Asset Legal and Compliance Department (“Legal and Compliance Department”) is responsible for administering and overseeing the proxy voting process. The gathering of proxies is coordinated through the Corporate Actions area of Investment Support (“Corporate Actions”). Research analysts and portfolio managers are responsible for determining appropriate voting positions on each proxy utilizing any applicable guidelines contained in these procedures.

Client Authority

The Investment Management Agreement for each client is reviewed at account start-up for proxy voting instructions. If an agreement is silent on proxy voting, but contains an overall delegation of discretionary authority or if the account represents assets of an ERISA plan, Western Asset will assume responsibility for proxy voting. The Legal and Compliance Department maintains a matrix of proxy voting authority.

Proxy Gathering

Registered owners of record, client custodians, client banks and trustees (“Proxy Recipients”) that receive proxy materials on behalf of clients should forward them to Corporate Actions. Proxy Recipients for new clients (or, if Western Asset becomes aware that the applicable Proxy Recipient for an existing client has changed, the Proxy Recipient for the existing client) are notified at start-up of appropriate routing to Corporate Actions of proxy materials received and reminded of their responsibility to forward all proxy materials on a timely basis. If Western Asset personnel other than Corporate Actions receive proxy materials, they should promptly forward the materials to Corporate Actions.

Proxy Voting

Once proxy materials are received by Corporate Actions, they are forwarded to the Legal and Compliance Department for coordination and the following actions:

Proxies are reviewed to determine accounts impacted.

Impacted accounts are checked to confirm Western Asset voting authority.

Legal and Compliance Department staff reviews proxy issues to determine any material conflicts of interest. (See conflicts of interest section of these procedures for further information on determining material conflicts of interest.)

If a material conflict of interest exists, (i) to the extent reasonably practicable and permitted by applicable law, the client is promptly notified, the conflict is disclosed and Western Asset obtains the client’s proxy voting instructions, and (ii) to the extent that it is not reasonably practicable or permitted by applicable law to notify the client and obtain such instructions (e.g., the client is a mutual fund or other commingled vehicle or is an ERISA plan client), Western Asset seeks voting instructions from an independent third party.

Legal and Compliance Department staff provides proxy material to the appropriate research analyst or portfolio manager to obtain their recommended vote. Research analysts and portfolio managers determine votes on a case-by-case basis taking into account the voting guidelines contained in these procedures. For avoidance of doubt, depending on the best interest of each individual client, Western Asset may vote the same proxy differently for different clients. The analyst’s or portfolio manager’s basis for their decision is documented and maintained by the Legal and Compliance Department.

Legal and Compliance Department staff votes the proxy pursuant to the instructions received in (d) or (e) and returns the voted proxy as indicated in the proxy materials.

Timing

Western Asset personnel act in such a manner to ensure that, absent special circumstances, the proxy gathering and proxy voting steps noted above can be completed before the applicable deadline for returning proxy votes.

Recordkeeping

Western Asset maintains records of proxies voted pursuant to Section 204-2 of the Advisers Act and ERISA DOL Bulletin 94-2. These records include:

A copy of Western Asset’s policies and procedures.

Copies of proxy statements received regarding client securities.

A copy of any document created by Western Asset that was material to making a decision how to vote proxies.

Each written client request for proxy voting records and Western Asset’s written response to both verbal and written client requests.

A proxy log including:

Issuer name;

Exchange ticker symbol of the issuer’s shares to be voted;

Committee on Uniform Securities Identification Procedures (“CUSIP”) number for the shares to be voted;

A brief identification of the matter voted on;

Whether the matter was proposed by the issuer or by a shareholder of the issuer;

Whether a vote was cast on the matter;

A record of how the vote was cast; and

Whether the vote was cast for or against the recommendation of the issuer’s management team.

Records are maintained in an easily accessible place for five years, the first two in Western Asset’s offices.

Disclosure

Part II of the WA Form ADV contains a description of Western Asset’s proxy policies. Clients will be provided a copy of these policies and procedures upon request. In addition, upon request, clients may receive reports on how their proxies have been voted.

Conflicts of Interest

All proxies are reviewed by the Legal and Compliance Department for material conflicts of interest. Issues to be reviewed include, but are not limited to:

Whether Western Asset (or, to the extent required to be considered by applicable law, its affiliates) manages assets for the company or an employee group of the company or otherwise has an interest in the company;

Whether Western Asset or an officer or director of Western Asset or the applicable portfolio manager or analyst responsible for recommending the proxy vote (together, “Voting Persons”) is a close relative of or has a personal or business relationship with an executive, director or person who is a candidate for director of the company or is a participant in a proxy contest; and

Whether there is any other business or personal relationship where a Voting Person has a personal interest in the outcome of the matter before shareholders.

Voting Guidelines

Western Asset’s substantive voting decisions turn on the particular facts and circumstances of each proxy vote and are evaluated by the designated research analyst or portfolio manager. The examples outlined below are meant as guidelines to aid in the decision making process.

Guidelines are grouped according to the types of proposals generally presented to shareholders. Part I deals with proposals which have been approved and are recommended by a company’s board of directors; Part II deals with proposals submitted by shareholders for inclusion in proxy statements; Part III addresses issues relating to voting shares of investment companies; and Part IV addresses unique considerations pertaining to foreign issuers.

I. Board Approved Proposals

The vast majority of matters presented to shareholders for a vote involve proposals made by a company itself that have been approved and recommended by its board of directors. In view of the enhanced corporate governance practices currently being implemented in public companies, Western Asset generally votes in support of decisions reached by independent boards of directors. More specific guidelines related to certain board-approved proposals are as follows:

1. Matters relating to the Board of Directors

Western Asset votes proxies for the election of the company’s nominees for directors and for board-approved proposals on other matters relating to the board of directors with the following exceptions:

Votes are withheld for the entire board of directors if the board does not have a majority of independent directors or the board does not have nominating, audit and compensation committees composed solely of independent directors.

Votes are withheld for any nominee for director who is considered an independent director by the company and who has received compensation from the company other than for service as a director.

Votes are withheld for any nominee for director who attends less than 75% of board and committee meetings without valid reasons for absences.

Votes are cast on a case-by-case basis in contested elections of directors.

2. Matters relating to Executive Compensation

Western Asset generally favors compensation programs that relate executive compensation to a company’s long-term performance. Votes are cast on a case-by-case basis on board-approved proposals relating to executive compensation, except as follows:

Except where the firm is otherwise withholding votes for the entire board of directors, Western Asset votes for stock option plans that will result in a minimal annual dilution.

Western Asset votes against stock option plans or proposals that permit replacing or repricing of underwater options.

Western Asset votes against stock option plans that permit issuance of options with an exercise price below the stock’s current market price.

Except where the firm is otherwise withholding votes for the entire board of directors, Western Asset votes for employee stock purchase plans that limit the discount for shares purchased under the plan to no more than 15% of their market value, have an offering period of 27 months or less and result in dilution of 10% or less.

3. Matters relating to Capitalization

The management of a company’s capital structure involves a number of important issues, including cash flows, financing needs and market conditions that are unique to the circumstances of each company. As a result, Western Asset votes on a case-by-case basis on board-approved proposals involving changes to a company’s capitalization except where Western Asset is otherwise withholding votes for the entire board of directors.

Western Asset votes for proposals relating to the authorization of additional common stock.

Western Asset votes for proposals to effect stock splits (excluding reverse stock splits).

Western Asset votes for proposals authorizing share repurchase programs.

4. Matters relating to Acquisitions, Mergers, Reorganizations and Other Transactions

Western Asset votes these issues on a case-by-case basis on board-approved transactions.

5. Matters relating to Anti-Takeover Measures

Western Asset votes against board-approved proposals to adopt anti-takeover measures except as follows:

Western Asset votes on a case-by-case basis on proposals to ratify or approve shareholder rights plans.

Western Asset votes on a case-by-case basis on proposals to adopt fair price provisions.

6. Other Business Matters

Western Asset votes for board-approved proposals approving such routine business matters such as changing the company’s name, ratifying the appointment of auditors and procedural matters relating to the shareholder meeting.

Western Asset votes on a case-by-case basis on proposals to amend a company’s charter or bylaws.

Western Asset votes against authorization to transact other unidentified, substantive business at the meeting.

II. Shareholder Proposals

SEC regulations permit shareholders to submit proposals for inclusion in a company’s proxy statement. These proposals generally seek to change some aspect of a company’s corporate governance structure or to change some aspect of its business operations. Western Asset votes in accordance with the recommendation of the company’s board of directors on all shareholder proposals, except as follows:

1. Western Asset votes for shareholder proposals to require shareholder approval of shareholder rights plans.

2. Western Asset votes for shareholder proposals that are consistent with Western Asset’s proxy voting guidelines for board-approved proposals.

3. Western Asset votes on a case-by-case basis on other shareholder proposals where the firm is otherwise withholding votes for the entire board of directors.

III. Voting Shares of Investment Companies

Western Asset may utilize shares of open or closed-end investment companies to implement its investment strategies. Shareholder votes for investment companies that fall within the categories listed in Parts I and II above are voted in accordance with those guidelines.

1. Western Asset votes on a case-by-case basis on proposals relating to changes in the investment objectives of an investment company taking into account the original intent of the fund and the role the fund plays in the clients’ portfolios.

2. Western Asset votes on a case-by-case basis all proposals that would result in increases in expenses (e.g., proposals to adopt 12b-1 plans, alter investment advisory arrangements or approve fund mergers) taking into account comparable expenses for similar funds and the services to be provided.

IV. Voting Shares of Foreign Issuers

In the event Western Asset is required to vote on securities held in non-U.S. issuers – i.e. issuers that are incorporated under the laws of a foreign jurisdiction and that are not listed on a U.S. securities exchange or the NASDAQ stock market, the following guidelines are used, which are premised on the existence of a sound corporate governance and disclosure framework. These guidelines, however, may not be appropriate under some circumstances for foreign issuers and therefore apply only where applicable.

1. Western Asset votes for shareholder proposals calling for a majority of the directors to be independent of management.

2. Western Asset votes for shareholder proposals seeking to increase the independence of board nominating, audit and compensation committees.

3. Western Asset votes for shareholder proposals that implement corporate governance standards similar to those established under U.S. federal law and the listing requirements of U.S. stock exchanges, and that do not otherwise violate the laws of the jurisdiction under which the company is incorporated.

4. Western Asset votes on a case-by-case basis on proposals relating to (1) the issuance of common stock in excess of 20% of a company’s outstanding common stock where shareholders do not have preemptive rights, or (2) the issuance of common stock in excess of 100% of a company’s outstanding common stock where shareholders have preemptive rights.

Retirement Accounts

For accounts subject to ERISA, as well as other Retirement Accounts, Western Asset is presumed to have the responsibility to vote proxies for the client. The Department of Labor (“DOL”) has issued a bulletin that states that investment managers have the responsibility to vote proxies on behalf of Retirement Accounts unless the authority to vote proxies has been specifically reserved to another named fiduciary. Furthermore, unless Western Asset is expressly precluded from voting the proxies, the DOL has determined that the responsibility remains with the investment manager.

In order to comply with the DOL’s position, Western Asset will be presumed to have the obligation to vote proxies for its Retirement Accounts unless Western Asset has obtained a specific written instruction indicating that: (a) the right to vote proxies has been reserved to a named fiduciary of the client, and (b) Western Asset is precluded from voting proxies on behalf of the client. If Western Asset does not receive such an instruction, Western Asset will be responsible for voting proxies in the best interests of the Retirement Account client and in accordance with any proxy voting guidelines provided by the client.

(a)(2): DATA TO BE PROVIDED BY FINANCIAL CONTROL

The following tables set forth certain additional information with respect to the fund’s investment professionals for the fund. Unless noted otherwise, all information is provided as of October 31, 2013.

Other Accounts Managed by Investment Professionals

The table below identifies the number of accounts (other than the fund) for which the fund’s investment professionals have day-to-day management responsibilities and the total assets in such accounts, within each of the following categories: registered investment companies, other pooled investment vehicles, and other accounts. For each category, the number of accounts and total assets in the accounts where fees are based on performance is also indicated.

‡

The numbers above reflect the overall number of portfolios managed by employees of Western Asset Management Company (“Western Asset”). Mr. Walsh is involved in the management of all the Firm’s portfolios, but they are not solely responsible for particular portfolios. Western Asset’s investment discipline emphasizes a team approach that combines the efforts of groups of specialists working in different market sectors. They are responsible for overseeing implementation of Western Asset’s overall investment ideas and coordinating the work of the various sector teams. This structure ensures that client portfolios benefit from a consensus that draws on the expertise of all team members.

(a)(3): Investment Professional Compensation

With respect to the compensation of the investment professionals, Western Asset’s compensation system assigns each employee a total compensation range, which is derived from annual market surveys that benchmark each role with its job function and peer universe. This method is designed to reward employees with total compensation reflective of the external market value of their skills, experience, and ability to produce desired results. Standard compensation includes competitive base salaries, generous employee benefits, and a retirement plan.

In addition, the subadviser’s employees are eligible for bonuses. These are structured to closely align the interests of employees with those of the subadviser, and are determined by the professional’s job function and pre-tax performance as measured by a formal review process. All bonuses are completely discretionary. The principal factor considered is an investment professional’s investment performance versus appropriate peer groups and benchmarks (e.g., a securities index and with respect to a fund, the benchmark set forth in the fund’s Prospectus to which the fund’s average annual total returns are compared or, if none, the benchmark set forth in the fund’s annual report). Performance is reviewed on a 1, 3 and 5 year basis for compensation—with 3 years having the most emphasis. The subadviser may also measure an investment professional’s pre-tax investment performance against other benchmarks, as it determines appropriate. Because investment professionals are generally responsible for multiple accounts (including the funds) with similar investment strategies, they are generally compensated on the performance of the aggregate group of similar accounts, rather than a specific account. Other factors that may be considered when making bonus decisions include client service, business development, length of service to the subadviser, management or supervisory responsibilities, contributions to developing business strategy and overall contributions to the subadviser’s business.

Finally, in order to attract and retain top talent, all professionals are eligible for additional incentives in recognition of outstanding performance. These are determined based upon the factors described above and include Legg Mason stock options and long-term incentives that vest over a set period of time past the award date.

Potential Conflicts of Interest

Conflicts of Interest

The manager, the subadviser and investment professionals have interests which conflict with the interests of the fund. There is no guarantee that the policies and procedures adopted by the manager, the subadviser and the fund will be able to identify or mitigate these conflicts of interest.

Some examples of material conflicts of interest include:

Allocation of Limited Time and Attention. An investment professional who is responsible for managing multiple funds and/or accounts may devote unequal time and attention to the management of those funds and/or accounts. An investment professional may not be able to formulate as complete a strategy or identify equally attractive investment opportunities for each of those funds and accounts as might be the case if he or she were to devote substantially more attention to the management of a single fund. Such an investment professional may make general determinations across multiple funds, rather than tailoring a unique approach for each fund. The effects of this conflict may be more pronounced where funds and/or accounts overseen by a particular investment professional have different investment strategies.

Allocation of Limited Investment Opportunities; Aggregation of Orders. If an investment professional identifies a limited investment opportunity that may be suitable for multiple funds and/or accounts, the opportunity may be allocated among these several funds or accounts, which may limit the fund’s ability to take full advantage of the investment opportunity. Additionally, the subadviser may aggregate transaction orders for multiple accounts for purpose of execution. Such aggregation may cause the price or brokerage costs to be less favorable to a particular client than if similar transactions were not being executed concurrently for other accounts. In addition, the subadviser’s trade allocation policies may result in the fund’s orders not being fully executed or being delayed in execution.

Pursuit of Differing Strategies. At times, an investment professional may determine that an investment opportunity may be appropriate for only some of the funds and/or accounts for which he or she exercises investment responsibility, or may decide that certain of the funds and/or accounts should take differing positions with respect to a particular security. In these cases, the investment professional may place separate transactions for one or more funds or accounts which may affect the market price of the security or the execution of the transaction, or both, to the detriment or benefit of one or more other funds and/or accounts. For example, an investment professional may determine that it would be in the interest of another account to sell a security that the fund holds long, potentially resulting in a decrease in the market value of the security held by the fund.

Cross Trades. Investment professionals may manage funds that engage in cross trades, where one of the manager’s funds or accounts sells a particular security to another fund or account managed by the same manager. Cross trades may pose conflicts of interest because of, for example, the possibility that one account sells a security to another account at a higher price than an independent third party would pay or otherwise enters into a transaction that it would not enter into with an independent party, such as the sale of a difficult-to-obtain security.

Selection of Broker/Dealers. Investment professionals may select or influence the selection of the brokers and dealers that are used to execute securities transactions for the funds and/or accounts that they supervise. In addition to executing trades, some brokers and dealers provide the subadviser with brokerage and research services, These services may be taken into account in the selection of brokers and dealers whether a broker is being selected to effect a trade on an agency basis for a commission or (as is normally the case for the funds) whether a dealer is being selected to effect a trade on a principal basis. This may result in the payment of higher brokerage fees and/or execution at a less favorable price than might have otherwise been available. The services obtained may ultimately be more beneficial to certain of the manager’s funds or accounts than to others (but not necessarily to the funds that pay the increased commission or incur the less favorable execution). A decision as to the selection of brokers and dealers could therefore yield disproportionate costs and benefits among the funds and/or accounts managed.

Variation in Financial and Other Benefits. A conflict of interest arises where the financial or other benefits available to an investment professional differ among the funds and/or accounts that he or she manages. If the amount or structure of the investment manager’s management fee and/or an investment professional’s compensation differs among funds and/or accounts (such as where certain funds or accounts pay higher management fees or performance-based management fees), the investment professional might be motivated to help certain funds and/or accounts over others. Similarly, the desire to maintain assets under management or to enhance the investment professional’s performance record or to derive other rewards, financial or otherwise, could influence the investment professional in affording preferential treatment to those funds and/or accounts that could most significantly benefit the investment professional. An investment professional may, for example, have an incentive to allocate favorable or limited opportunity investments or structure the timing of investments to favor such funds and/or accounts. Also, an investment professional’s or the manager’s or the subadviser’s desire to increase assets under management could influence the investment professional to keep a fund open for new investors without regard to potential benefits of closing the fund to new investors. Additionally, the investment professional might be motivated to favor funds and/or accounts in which he or she has an ownership interest or in which the investment manager and/or its

affiliates have ownership interests. Conversely, if an investment professional does not personally hold an investment in the fund, the investment professional’s conflicts of interest with respect to the fund may be more acute.

Related Business Opportunities. The investment manager or its affiliates may provide more services (such as distribution or recordkeeping) for some types of funds or accounts than for others. In such cases, an investment professional may benefit, either directly or indirectly, by devoting disproportionate attention to the management of funds and/or accounts that provide greater overall returns to the investment manager and its affiliates.
