Fund objectives

The Fund’s primary investment objective is to seek a high level of current income which is exempt from regular federal income taxes,* consistent with the preservation of capital. As a secondary investment objective, the Fund intends to enhance portfolio value by purchasing tax-exempt securities that, in the opinion of the investment manager, may appreciate in value relative to other similar obligations in the marketplace.

Under normal market conditions, the Fund invests substantially all of its assets in a diversified portfolio of tax-exempt securities that are rated investment grade at the time of purchase by at least one rating agency and that the investment manager believes do not involve undue risk to income or principal.

Investment commentary

Economic review

Economic activity in the U.S. was somewhat mixed during the six months ended May 31, 2018 (the “reporting period”). Looking back, the U.S. Department of Commerce reported that third and fourth quarter 2017 U.S. gross domestic product (“GDP”)ⁱ growth was 3.2% and 2.9%, respectively. Finally, the U.S. Department of Commerce’s final reading for first quarter 2018 GDP growth — released after the reporting period ended — was 2.0%. More modest GDP growth in the first quarter reflected decelerations in personal consumption expenditures (“PCE”), exports, state and local government spending, and federal government spending and a downturn in residential fixed investment. These movements were partly offset by a smaller decrease in private inventory investment and a larger increase in nonresidential fixed investment.

Job growth in the U.S. was solid overall and supported the economy during the reporting period. When the reporting period ended on May 31, 2018, the unemployment rate was 3.8%, as reported by the U.S. Department of Labor. This was the lowest unemployment rate since April 2000. The percentage of longer-term unemployed declined during the reporting period. In May 2018, 19.4% of Americans looking for a job had been out of work for more than six months, versus 22.9% when the period began.

Investment commentary (cont’d)

Market review

Q. How did the Federal Reserve Board (the “Fed”)ⁱⁱ respond to the economic environment?

A. The Fed increased the federal funds rateⁱⁱⁱ twice during the reporting period. Looking back, at its meeting that concluded on September 20, 2017 — before the reporting period began — the Fed kept rates on hold but reiterated its intention to begin reducing its balance sheet, saying, “In October, the Committee will initiate the balance sheet normalization program….” At its meeting that ended on December 13, 2017, the Fed raised rates to a range between 1.25% and 1.50%. As expected, the Fed kept rates on hold at its meeting that concluded on January 31, 2018. However, at its meeting that ended on March 21, 2018, the Fed again raised the federal funds rate, moving it to a range between 1.50% and 1.75%. Finally, at its meeting that concluded on June 13, 2018 — after the reporting period ended — the Fed raised the federal funds rate to a range between 1.75% and 2.00%.

Q. Did Treasury yields trend higher or lower during the reporting period?

A. Both short-term and longer-term Treasury yields moved higher during the six-month reporting period ended May 31, 2018. The yield for the two-year Treasury note began the reporting period at 1.78% — equaling its low for the period — and ended the period at 2.40%. Its peak for the period of 2.59% occurred on May 22, 2018. The yield for the ten-year Treasury began the reporting period at 2.42% and ended the period at 2.83%. The low for the period of 2.33% occurred on December 6, 2017 and the high for the period of 3.11% took place on May 17, 2018.

Q. How did the municipal bond market perform versus the taxable bond market over the reporting period?

A. The municipal bond market outperformed its taxable bond counterpart on a relative basis during the reporting period. For the six months ended May 31, 2018, the Bloomberg Barclays Municipal Bond Index^iv and the Bloomberg Barclays U.S. Aggregate Index^v returned 0.71% and -1.04%, respectively. Both municipal and taxable bonds were negatively impacted by the rising interest rate environment. The municipal market’s relative outperformance was partially due to overall solid fundamentals and periods of positive investor demand.

Performance review

For the six months ended May 31, 2018, Western Asset Municipal Partners Fund Inc. returned 0.54% based on its net asset value (“NAV”)^vi and -4.15% based on its New York Stock Exchange (“NYSE”) market price per share. The Fund’s unmanaged benchmark, the Bloomberg Barclays Municipal Bond Index, returned 0.71% for the same period. The Lipper General & Insured Municipal Debt (Leveraged) Closed-End Funds Category Average^vii returned 0.85% 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 this six-month period, the Fund made distributions to shareholders totaling $0.38 per share. As of May 31, 2018, the Fund estimates that all of the distributions were

Investment commentary (cont’d)

the uncertainty inherent in all investments, there can be no assurance that the Fund will achieve its investment objective. The Fund’s common stock is traded on the New York Stock Exchange. Similar to stocks, the Fund’s share price will fluctuate with market conditions and at the time of sale, may be worth more or less than the original investment. Shares of closed-end funds often trade at a discount to their net asset value. Diversification does not assure against market loss. The Fund’s investments are subject to a number of risks, including interest rate risk, credit risk, leveraging risk and management risk. As interest rates rise, bond prices fall, reducing the value of the Fund’s fixed-income securities. The Fund may invest in lower-rated high yield bonds or “junk bonds”, which are subject to greater liquidity and credit risk (risk of default) than higher rated obligations. 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. The Fund may invest in securities of other investment companies. To the extent it does, Fund stock holders will indirectly pay a portion of the operating costs of such companies, in addition to the expenses that the Fund bears directly in connection with its own operation. Investing in securities issued by other investment companies, including exchange-traded funds (“ETFs”) that invest primarily in municipal securities, involves risks similar to those of investing directly in the securities in which those investment companies invest. Leverage may result in greater volatility of NAV and the market price of common shares and increases a shareholder’s risk of loss.

All investments are subject to risk including the possible loss of principal. Past performance is no guarantee of future results. All index performance reflects no deduction for fees, expenses or taxes. Please note that an investor cannot invest directly in an index.

Western Asset Municipal Partners Fund Inc. 2018 Semi-Annual Report 23

Notes to financial statements (unaudited)

1. Organization and significant accounting policies

Western Asset Municipal Partners Fund Inc. (the “Fund”) was incorporated in Maryland on November 24, 1992 and is registered as a diversified, closed-end management investment company under the Investment Company Act of 1940, as amended (the “1940 Act”). The Board of Directors authorized 100 million shares of $0.001 par value common stock. The Fund’s primary investment objective is to seek a high level of current income which is exempt from federal income taxes, consistent with the preservation of capital. As a secondary investment objective, the Fund intends to enhance portfolio value by purchasing tax exempt securities that, in the opinion of the investment manager, may appreciate in value relative to other similar obligations in the marketplace.

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. Investments in open-end funds are valued at the closing net asset value per share of each fund on the day of valuation. 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 Atlantic Fund Valuation Committee (the “Valuation Committee”). The Valuation Committee, pursuant to the policies

24 Western Asset Municipal Partners Fund Inc. 2018 Semi-Annual Report

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.

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)

Western Asset Municipal Partners Fund Inc. 2018 Semi-Annual Report 25

Notes to financial statements (unaudited) (cont’d)

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

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

ASSETS
Description	Quoted Prices (Level 1)		Other Significant Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total
Municipal Bonds†		—	$	238,939,117		—	$	238,939,117
Short-Term Investments†		—		200,000		—		200,000
Total Investments		—	$	239,139,117		—	$	239,139,117

† See Schedule of Investments for additional detailed categorizations.    

(b) Net asset value. The net asset value (“NAV”) of the Fund’s common stock is determined no less frequently than the close of business on the Fund’s last business day of each week (generally Friday) and on the last business day of the month. It is determined by dividing the value of the net assets available to common stock by the total number of shares of common stock outstanding. For the purpose of determining the NAV per share of the common stock, the value of the Fund’s net assets shall be deemed to equal the value of the Fund’s assets less (1) the Fund’s liabilities including the aggregate liquidation value (i.e., $50,000 per outstanding share) of the Variable Rate Demand Preferred Stock (“VRDPS”), and (2) the aggregate liquidation value (i.e., $50,000 per outstanding share) of the Auction Rate Cumulative Preferred Stock (“ARCPS”).

(c) Cash flow information. The Fund invests in securities and distributes dividends from net investment income and net realized gains, which are paid in cash and may be reinvested at the discretion of shareholders. These activities are reported in the Statement of Changes in Net Assets and additional information on cash receipts and cash payments are presented in the Statement of Cash Flows.

(d) Security transactions and investment income. Security transactions are accounted for on a trade date basis. Interest income (including interest income from payment-in-kind securities), adjusted for amortization of premium and accretion of discount, is recorded on the accrual basis. The cost of investments sold is 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 to common shareholders from net investment income of the Fund, if any, are declared quarterly and paid on a monthly basis. The actual source of the Fund’s monthly distributions may be from net investment income, return of capital or a combination of both. Shareholders will be informed of the tax characteristics of the distributions after the close of the fiscal year. The Fund intends to

26 Western Asset Municipal Partners Fund Inc. 2018 Semi-Annual Report

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 common shareholders of the Fund. Distributions to common shareholders of net realized gains, if any, are taxable and are declared at least annually. Distributions to common 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.

Distributions to holders of ARCPS are accrued daily and paid on a weekly basis and are determined as described in Note 6. Distributions to holders of VRDPS are accrued on a daily basis and paid monthly as described in Note 5 and are treated as an operating expense as required by GAAP. For tax purposes, the payments made to the holders of the Fund’s VRDPS are treated as dividends or distributions.

(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 November 30, 2017, 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 value per share.

2. Investment management agreement and other transactions with affiliates

Legg Mason Partners Fund Advisor, LLC (“LMPFA”) is the Fund’s investment manager and Western Asset Management Company, LLC (formerly known as Western Asset Management Company) (“Western Asset”) is the Fund’s subadviser. LMPFA and Western Asset are wholly-owned subsidiaries of Legg Mason, Inc. (“Legg Mason”).

LMPFA provides administrative and certain oversight services to the Fund. The Fund pays LMPFA an investment management fee, calculated daily and paid monthly, at an annual rate of 0.55% of the Fund’s average weekly net assets. For purposes of calculating this fee, the aggregate liquidation value of the preferred stock is not deducted in determining the Fund’s average daily net assets.

Western Asset Municipal Partners Fund Inc. 2018 Semi-Annual Report 27

Notes to financial statements (unaudited) (cont’d)

LMPFA delegates to Western Asset the day-to-day portfolio management of the Fund. For its services, LMPFA pays Western Asset monthly 70% of the net management fee it receives from the Fund.

All officers and one Director of the Fund are employees of Legg Mason or its affiliates and do not receive compensation from the Fund.

The Fund is permitted to purchase or sell securities, typically short-term variable rate demand obligations, from or to certain other affiliated funds or portfolios under specified conditions outlined in procedures adopted by the Board of Directors. The procedures have been designed to provide assurance that any purchase or sale of securities by the Fund from or to another fund or portfolio that is, or could be considered, an affiliate by virtue of having a common investment manager or subadviser (or affiliated investment manager or subadviser), common Directors and/or common officers complies with Rule 17a-7 under the 1940 Act. Further, as defined under the procedures, each transaction is effected at the current market price.

4. Derivative instruments and hedging activities

5. Variable rate demand preferred stock

On March 11, 2015, the Fund completed a private offering of 1,330 shares of Series 1 Variable Rate Demand Preferred Stock (“VRDPS”). Net proceeds from the offering were used by the Fund to repurchase outstanding shares of Series M Auction Rate Cumulative Preferred Stock (“ARCPS”) that had been accepted for payment pursuant to the tender offer (See Note 6). Offering costs incurred by the Fund in connection with the VRDPS issuance are being amortized to expense over the life of the VRDPS.

28 Western Asset Municipal Partners Fund Inc. 2018 Semi-Annual Report

The table below summarizes the key terms of Series 1 of the VRDPS at May 31, 2018.

Series	Mandatory Redemption Date		Shares		Liquidation Preference Per Share		Aggregate Liquidation Value
Series 1		3/11/2045		1,330	$	50,000	$	66,500,000

The VRDPS shares are not listed on any securities exchange or automated quotation system. For financial reporting purposes, the VRDPS shares are considered debt of the Fund; therefore, the liquidation value, which approximates fair value of the VRDPS shares, is recorded as a liability on the Statement of Assets and Liabilities.

Holders of VRDPS have the right to tender their VRDPS shares for remarketing at a price equal to the liquidation preference amount plus all accumulated but unpaid dividends and at a date which is no earlier than the seventh day following delivery of the notice to the tender and paying agent. The VRDPS shares include a liquidity feature that allows VRDPS holders to have their shares purchased by the liquidity provider with whom the Fund has contracted in the event of a failed remarketing where purchase orders are not sufficient in number to be matched with the sale orders. The Fund is required to redeem the VRDPS shares owned by the liquidity provider after six months of continuous, unsuccessful remarketing. The Fund pays a monthly remarketing fee at the annual rate of 0.10% of the liquidation value of each VRDPS share outstanding on the first calendar day of the preceding calendar month. These fees are shown as remarketing fees on the Statement of Operations.

Holders of VRDPS are entitled to receive monthly cumulative cash dividends, payable on the first business day of each calendar month, at a variable rate set weekly by the remarketing agent. The dividend rate is generally based upon a spread over a base rate and cannot exceed a maximum rate. In the event of a failed remarketing, the dividend rate will reset to the maximum rate. The maximum rate is determined, in part, based upon the long-term rating assigned to the VRDPS. In the event the Fund fails to make a scheduled dividend payment, all outstanding shares of the VRDPS are subject to mandatory tender.

Subject to certain conditions, the VRDPS shares may be redeemed, in whole or in part, at any time at the option of the Fund. The redemption price per share is equal to the liquidation value per share plus any accumulated but unpaid dividends. The Fund is required to redeem its VRDPS on the mandatory redemption date, March 11, 2045. In addition, the Fund is required to redeem certain of the VRDPS shares if the Fund fails to maintain certain asset coverage and rating agency guidelines.

The Fund has entered into a fee agreement with the liquidity provider that requires monthly payment of an annual liquidity fee. These fees are shown as liquidity fees on the Statement of Operations. The fee agreement between the Fund and the liquidity provider is scheduled to terminate on March 8, 2019. The Fund has the right, which is exercisable 120 to

Western Asset Municipal Partners Fund Inc. 2018 Semi-Annual Report 29

Notes to financial statements (unaudited) (cont’d)

90 days prior to the scheduled termination date, to request that the liquidity provider extend the term of the agreement for an additional period. The Fund may also terminate the agreement early. In the event the fee agreement is not renewed or is terminated in advance, and the Fund does not enter into a fee agreement with an alternate liquidity provider, the VRDPS will be subject to mandatory purchase by the liquidity provider prior to the termination of the fee agreement. The Fund is required to redeem any VRDPS purchased by the liquidity provider six months after the purchase date.

The VRDPS ranks senior to the Fund’s outstanding common stock and on parity with any other preferred stock. The Fund may not declare dividends or make other distributions on shares of its common stock unless the Fund has declared and paid full cumulative dividends on the VRDPS, due on or prior to the date of the common stock dividend or distribution, and meets the VRDPS asset coverage and rating agency requirements.

The holders of the VRDPS have one vote per share and vote together with the holders of common stock of the Fund as a single class except on matters affecting only the holders of VRDPS or the holders of common stock. Pursuant to the 1940 Act, holders of the VRDPS have the right to elect two Directors of the Fund, voting separately as a class.

The annualized dividend rate for the VRDPS shares for the six months ended May 31, 2018 was 1.495%. VRDPS shares issued and outstanding remained constant during the six months ended May 31, 2018.

6. Auction rate cumulative preferred stock

On April 2, 1993, the Fund closed its public offering of 800 shares of $0.001 par value Auction Rate Cumulative Preferred Stock, Series M (“Preferred Stock”), at an offering price of $50,000 per share. On July 20, 2007, the Fund acquired the Preferred Stock of Western Asset Municipal Partners Fund II Inc. On October 1, 1993, Western Asset Municipal Partners Fund II Inc. closed its public offering of 900 shares of $0.001 par value Preferred Stock at an offering price of $50,000 per share.

On January 22, 2015, the Fund announced that it had commenced an issuer tender offer for up to 100% of its outstanding ARCPS at a price equal to 90% of the liquidation preference of $50,000 per share (or $45,000 per share), plus any unpaid dividends accrued through March 6, 2015, the expiration date of the tender offer.

The Fund’s tender offer was conditioned upon the Fund closing on the private offering of VRDPS with an aggregate liquidation preference at least equal to the aggregate liquidation preference of ARCPS accepted for tender.

On March 11, 2015, the Fund announced the final results for its issuer tender offer and all shares that were validly tendered and not withdrawn during the offering period were accepted for payment. The Fund accepted for payment 1,330 Series M ARCPS, which represented 78.24% of the outstanding ARCPS. The ARCPS that were not tendered will remain outstanding. The difference between the liquidation preference of the ARCPS and the actual

30 Western Asset Municipal Partners Fund Inc. 2018 Semi-Annual Report

purchase price of the tendered ARCPS was recognized by the Fund in the Statement of Changes in Net Assets as an increase in net assets applicable to common shares resulting from the tender and repurchase of the ARCPS by the Fund.

On April 25, 2018, the Fund repurchased 2 Series M ARCPS in a private transaction at a price equal to 85% of the liquidation preference of $50,000 per share (of $42,500 per share), plus any unpaid dividends. The difference between the liquidation preference of the ARCPS and the actual purchase price of the tendered ARCPS was recognized by the Fund in the Statement of Changes in Net Assets as an increase in the assets applicable to common shares resulting from the tender and repurchase of the ARCPS by the Fund.

At May 31, 2018, the Fund had 368 shares of Preferred Stock outstanding with a liquidation preference of $50,000 per share plus an amount equal to accumulated but unpaid dividends (whether or not earned or declared) and subject to certain restrictions, are redeemable in whole or in part.

Dividend rates generally reset every 7 days and are determined by auction procedures. The dividend rate cannot exceed a certain maximum rate, including in the event of a failed auction. The maximum rate is calculated using the higher of 110% of the taxable equivalent of the short-term municipal bond rate and 110% of the prevailing 30 day AA commercial paper rate. The Fund may pay higher maximum rates if the rating of the Fund’s Preferred Stock were to be lowered by the rating agencies. To the extent capital gains and other taxable income are allocated to holders of Preferred Shares for tax purposes, the Fund will likely have to pay higher dividends to holders of Preferred Shares to compensate them for the increased tax liability to them resulting from such allocation. Due to failed auctions experienced by the Fund’s Preferred Stock starting on February 15, 2008, the Fund pays the applicable maximum rate. The dividend rates ranged from 1.573% to 2.860% during the six months ended May 31, 2018. At May 31, 2018, the dividend rate was 2.090%.

After each auction, the auction agent will pay to each broker/dealer, from monies the Fund provides, a participation fee. For the period of the report and for all previous periods since the ARCPS have been outstanding, the participation fee has been paid at the annual rate of 0.25% of the purchase price of the ARCPS that the broker/dealer places at the auction. However, on August 3, 2009 and December 28, 2009, Citigroup Global Markets Inc. (“CGM”) and Merrill Lynch, Pierce, Fenner & Smith Inc., respectively, reduced their participation fee to an annual rate of 0.05% of the purchase price of the ARCPS, in the case of a failed auction. Effective June 1, 2010, Wells Fargo Advisors, LLC reduced its participation fee to an annual rate of 0.10% of the purchase price of the ARCPS, in the case of a failed auction. For the six months ended May 31, 2018, the Fund paid $11,706 to participating broker/dealers.

The Fund is subject to certain restrictions relating to the Preferred Stock. The Fund may not declare dividends or make other distributions on shares of common stock or purchase any such shares if, at the time of the declaration, distribution or purchase, asset coverage with

Western Asset Municipal Partners Fund Inc. 2018 Semi-Annual Report 31

Notes to financial statements (unaudited) (cont’d)

respect to the outstanding Preferred Stock would be less than 200%. The Preferred Stock is also subject to mandatory redemption at $50,000 per share plus any accumulated or unpaid dividends, whether or not declared, if certain requirements relating to the composition of the assets and liabilities of the Fund as set forth in its Articles Supplementary are not satisfied.

The Preferred Stock Shareholders are entitled to one vote per share and generally vote with the common stock shareholders but vote separately as a class to elect two directors and on certain matters affecting the rights of the Fund’s Preferred Stock. The issuance of Preferred Stock poses certain risks to holders of common stock, including, among others, the possibility of greater market price volatility, and in certain market conditions, the yield to holders of common stock may be adversely affected. The Fund is required to maintain certain asset coverages with respect to the Preferred Stock. If the Fund fails to maintain these coverages and does not cure any such failure within the required time period, the Fund is required to redeem a requisite number of the Preferred Stock in order to meet the applicable requirement. The Preferred Stock is otherwise not redeemable by holders of the shares. Additionally, failure to meet the foregoing asset requirements would restrict the Fund’s ability to pay dividends to common shareholders.

7. Distributions to common shareholders subsequent to May 31, 2018

The following distributions to common shareholders have been declared by the Fund’s Board of Directors and are payable subsequent to the period end of this report:

Record Date	Payable Date		Amount
5/25/2018		6/01/2018	$	0.0625
6/22/2018		7/02/2018	$	0.0575
7/20/2018		8/01/2018	$	0.0575
8/24/2018		9/04/2018	$	0.0575

8. Stock repurchase program

On November 16, 2015, the Fund announced that the Fund’s Board of Directors (the “Board”) had authorized the Fund to repurchase in the open market up to approximately 10% of the Fund’s outstanding common stock when the Fund’s shares are trading at a discount to net asset value. The Board has directed management of the Fund to repurchase shares of common stock at such times and in such amounts as management reasonably believes may enhance stockholder value. The Fund is under no obligation to purchase shares at any specific discount levels or in any specific amounts. During the six months ended May 31, 2018, the Fund did not repurchase any shares.

9. Deferred capital losses

As of November 30, 2017, the Fund had deferred capital losses of $330,613, which have no expiration date, that will be available to offset future taxable capital gains.

32 Western Asset Municipal Partners Fund Inc. 2018 Semi-Annual Report

10. Other

Tax reform legislation commonly known as the Tax Cuts and Jobs Act (the “Tax Act”) was enacted on December 22, 2017. Although the Tax Act does not amend any provisions that directly address qualification or taxation of a regulated investment company (“RIC”), the Tax Act does change the taxation of entities in which some RICs invest, the tax treatment of income derived from those entities and the taxation of RIC investors. The application of certain provisions in the Tax Act is uncertain so the effects on the funds and shareholders cannot be predicted. Legislative or administrative changes could be enacted at any time and could have prospective or retroactive effect.

Provisions under the Tax Act may cause RICs to increase the amount of or accelerate the recognition of taxable income and may eliminate the deductibility of certain expenses. Such consequences could lead to an increase in the amount of taxable income recognized by a RIC as well as an increase in the amount of taxable income distributed to RIC shareholders. Additionally, the new provisions under the Tax Act are expected to have a varying impact among funds with different investment objectives and strategies.

11. Subsequent event

On June 14, 2018, the Fund repurchased 1 Series M ARCPS in a private transaction at a price equal to 85% of the liquidation preference of $50,000 per share (of $42,500 per share), plus any unpaid dividends.

Dividend reinvestment plan (unaudited)

On December 15, 2016, the Fund announced that the Board of Directors has authorized changes to the Fund’s Dividend Reinvestment Plan (the “Plan”) with respect to dividend reinvestment determinations and transaction fees for Plan participants selling their shares. A copy of the revised Plan is included below.

Effective July 1, 2017, the Fund uses the dividend payment date to determine if new shares are issued or shares are purchased in the open market for Plan participants reinvesting their distributions. If on the payment date the closing market price (plus $0.03 per share commission) is at or above the net asset value (“NAV”), the Fund will issue new shares of common stock. Newly issued shares of common stock will be issued at a price equal to the greater of (a) the NAV per share on the date prior to issuance or (b) 95% of the closing market price per share. If the closing market price (plus $0.03 per share commission) is lower than the NAV per share on the payment date, the Plan Agent will receive the distribution in cash and purchase common stock in the open market. In addition, effective July 1, 2017, fees paid by Plan participants to sell Fund shares increased, with Plan participants paying a $5.00 transaction fee plus a $0.05 per share commission upon a sale of shares held pursuant to the Plan.

Revised dividend reinvestment plan:

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

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

(1) If the market price of the Common Stock (plus $0.03 per share commission) on the payment date (or, if the payment date is not a NYSE trading day, the immediately preceding trading day) is equal to or exceeds the net asset value per share of the Common Stock at the close of trading on the NYSE on the payment date, the Fund will issue new Common Stock at a price equal to the greater of (a) the net asset value per share at the close of trading on the NYSE on the payment date or (b) 95% of the market price per share of the Common Stock on the payment date.

(2) If the net asset value per share of the Common Stock exceeds the market price of the Common Stock (plus $0.03 per share commission) at the close of trading on the NYSE on the payment date, the Plan Agent will receive the dividend or distribution in cash and will buy Common Stock in the open market, on the NYSE or elsewhere, for your account as soon as practicable commencing on the trading day following the payment date and terminating no later than the earlier of (a) 30 days after the dividend

Western Asset Municipal Partners Fund Inc. 35

Dividend reinvestment plan (unaudited) (cont’d)

or distribution payment date, or (b) the payment date for the next succeeding dividend or distribution to be made to the stockholders; except when necessary to comply with applicable provisions of the federal securities laws. If during this period: (i) the market price (plus $0.03 per share commission) rises so that it equals or exceeds the net asset value per share of the Common Stock at the close of trading on the NYSE on the payment date before the Plan Agent has completed the open market purchases or (ii) if the Plan Agent is unable to invest the full amount eligible to be reinvested in open market purchases, the Plan Agent will cease purchasing Common Stock in the open market and the Fund shall issue the remaining Common Stock at a price per share equal to the greater of (a) the net asset value per share at the close of trading on the NYSE on the day prior to the issuance of shares for reinvestment or (b) 95% of the then current market price per share.

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

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

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

The Fund reserves the right to amend or terminate the Plan if, in the judgment of the Board of Directors, the change is warranted. The Plan may be terminated, amended or supplemented by the Fund upon notice in writing mailed to stockholders at least 30 days prior to the record date for the payment of any dividend or distribution by the Fund for which the termination or amendment is to be effective. Upon any termination, you will be sent cash for any fractional share of Common Stock in your account. You may elect to notify the Plan Agent in advance of such termination to have the Plan Agent sell part or all of your Common Stock on

36 Western Asset Municipal Partners Fund Inc.

your behalf. Additional information about the Plan and your account may be obtained from the Plan Agent at 462 South 4th Street, Suite 1600, Louisville, KY 40202 or by calling the Plan Agent at 1-888-888-0151.
