Investment commentary

Economic review

The U.S. economy continued to grow over the six months ended June 30, 2013 (the “reporting period”), but the pace was far from robust. 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 improved, as first quarter 2013 GDP growth was 1.1%. Accelerating growth was due, in part, to strengthening consumer spending, which rose 2.3% during the first quarter, versus a 1.7% increase during the previous quarter. The U.S. Department of Commerce’s initial reading for second quarter 2013 GDP growth, released after the reporting period ended, was 1.7%. This increase was partially driven by increases in non-residential fixed investment and exports, along with a smaller decline in federal government spending versus the previous quarter.

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 7.9%. Unemployment then fell to 7.7% in February, 7.6% in March and 7.5% in April. It then edged up to 7.6% in May and was unchanged in June. In an encouraging sign, an average of almost 202,000 jobs were created per month during the first half of 2013. In contrast, the monthly average was roughly 183,000 in 2012. In addition, the percentage of longer-term unemployed has declined, as roughly 36.7% of the 11.8 million Americans looking for work in June 2013 have been out of work for more than six months, versus 38.1% in January 2013.

Meanwhile, the housing market brightened, as sales generally improved and home prices continued to rebound. According to the National Association of Realtors (“NAR”), existing-home sales dipped 1.2% on a seasonally adjusted basis in June 2013 versus the previous month and were 1.52% higher than in June 2012. In addition, the NAR reported that the median existing-home price for all housing types was $214,200 in June 2013, up 13.5% from June 2012. This marked the sixteenth consecutive month that home prices rose compared to the same period a year earlier. While the inventory of homes available for sale rose 1.9% in June 2013 to a 5.2 month supply at the current sales pace, it was 7.6% lower than in June 2012.

While manufacturing activity was weak in many international developed countries, it was generally positive in the U.S. Based on the Institute for Supply Management’s Purchasing Managers’ Index (“PMI”) ii , the U.S. manufacturing sector expanded during the first four months of the reporting period. Manufacturing then experienced a setback, falling from 50.7 in April 2013 to 49.0 in May (a reading below 50 indicates a contraction, whereas a reading above 50 indicates an expansion). However, manufacturing then moved back into expansion territory in June, as the PMI increased to 50.9. During June, 12 of the 18 industries within the PMI expanded, versus 10 expanding the prior month.

Market review

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

A. The Fed 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, prior to the beginning of the reporting period, 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 a 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.” This initially triggered a sharp sell-off in both the stock and bond markets. While the stock market subsequently rallied and reached a new record high on July 12, the bond market did not rebound as sharply. As a result, Treasury yields remained sharply higher than they were prior to Chairman Bernanke’s press conference. At its meeting that ended on July 31, 2013, after the reporting period ended, the Fed did not institute any policy changes and left its $85 billion a month asset purchase program intact.

Q. Did Treasury yields trend higher or lower during the six months ended June 30, 2013?

A. Both short- and long-term Treasury yields moved sharply higher during the reporting period. When the period began, the yield on the two-year Treasury was 0.25%. It fell as low as 0.20% in late April/early May 2013 and was as high as 0.43% on June 25, 2013, before ending the period at 0.36%. The yield on the ten-year Treasury began the period at 1.78%. Ten-year Treasuries reached a low of 1.66% in early May 2013 and peaked at 2.60% on June 25, 2013 before edging down to 2.52% at the end of the period.

Q. What was the inflationary environment during the reporting period?

A. Inflation was relatively benign during the reporting period. For the six months ended June 30, 2013, the seasonally unadjusted rate of inflation, as measured by the Consumer Price Index for All Urban Consumers (“CPI-U”) v , was 1.70%. The CPI-U less food and energy was 1.13% over the same time frame. Inflation-protected securities generated weak results during the reporting period due to moderating expectations for inflation and rising interest rates. During the six months ended June 30, 2013, the Barclays U.S. TIPS Index vi fell 7.39%.

Investment commentary (cont’d)

Q. What factors impacted the spread sectors (non-Treasuries) during the reporting period?

A. Most spread sectors performed poorly during the reporting period. Spread sector demand was often solid during the first four months of the period as investors looked to generate incremental yield in the low interest rate environment. Even so, there were several periods of volatility given a number of macro issues, including the European sovereign debt crisis, mixed economic data and concerns related to the U.S. “fiscal cliff” and sequestration. The spread sectors then weakened over the last two months of the period amid sharply rising interest rates given the Fed’s plan to begin tapering its asset purchase program sooner than previously anticipated. The majority of spread sectors generated negative absolute returns and performed largely in line with equal-duration vii Treasuries during the reporting period as a whole. For the six months ended June 30, 2013, the Barclays U.S. Aggregate Index viii fell 2.44%.

Q. How did the high-yield market perform over the six months ended June 30, 2013?

A. The U.S. high-yield bond market was one of the few spread sectors to generate a positive return during the reporting period. The asset class, as measured by the Barclays U.S. Corporate High Yield — 2% Issuer Cap Index ix , posted positive returns during the first four months of the period. Risk appetite was often solid during that time as investors were drawn to higher yielding securities. However, the high-yield market gave back a large portion of previous gains in May and June. All told, the high-yield market gained 1.42% for the six months ended June 30, 2013.

Q. How did the emerging market debt asset class perform over the reporting period?

A. The asset class generated poor results during the six months ended June 30, 2013. Aside from a brief rally in April 2013, the asset class fell during the other five months of the reporting period. This weakness was triggered by a number of factors, including concerns over moderating global growth, fears of a “hard landing” for China’s economy, generally weaker commodity prices and sharply rising U.S. interest rates. Overall, the JPMorgan Emerging Markets Bond Index Global (“EMBI Global”) x fell 8.22% over the six months ended June 30, 2013.

Performance review

For the six months ended June 30, 2013, Western Asset Inflation Management Inc. returned -7.48% based on its net asset value (“NAV”) xi and -10.76% based on its New York Stock Exchange (“NYSE”) market price per share. The Fund’s unmanaged benchmark, the Barclays U.S. TIPS Index, returned -7.39% for the same period. The Lipper Corporate Debt BBB-Rated Closed-End Funds Category Average xii returned -3.58% over the same time frame. Please note that Lipper performance returns are based on each fund’s NAV.

During this six-month period, the Fund made distributions to shareholders totaling $0.30 per share, which may have included a return of capital. The performance table shows the Fund’s six-month total return based on its NAV and market price as of June 30, 2013. Past performance is no guarantee of future results.

RISKS: If interest rates rise, but the rate of inflation does not, the Fund’s performance will be adversely affected. The Fund is subject to the risks associated with inflation-protected securities (“IPS”). Risks associated with IPS investments include liquidity risk, interest rate risk, prepayment risk, extension risk and deflation risk. Income distributions of the Fund are likely to fluctuate more than those of a conventional bond fund. Changes in inflation will cause the Fund’s income to fluctuate, sometimes substantially. Periods of deflation may adversely affect the Fund’s NAV. As interest rates rise, bond prices fall, reducing the value of the Fund’s fixed-income holdings. The Fund is non-diversified, which means that it is permitted to invest a higher percentage of its assets in any one issuer than a diversified fund. This may magnify the Fund’s losses from events affecting a particular issuer. Foreign securities are subject to certain risks of overseas investing, including currency fluctuations and changes in political and economic conditions. These risks are greater in emerging markets. High-yield bonds involve greater credit and liquidity risks

than investment grade bonds. 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. Leverage may result in greater volatility of NAV and the market price of common shares and increases a shareholder’s risk of loss. There is no assurance that the Fund’s leveraging strategy will be successful.

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.

The information provided is not intended to be a forecast of future events, a guarantee of future results or investment advice. Views expressed may differ from those of the firm as a whole.

iii 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.

iv The federal funds rate is the rate charged by one depository institution on an overnight sale of immediately available funds (balances at the Federal Reserve) to another depository institution; the rate may vary from depository institution to depository institution and from day to day.

v The Consumer Price Index for All Urban Consumers (“CPI-U”) is a measure of the average change in prices over time of goods and services purchased by households, which covers approximately 87% of the total population and includes, in addition to wage earners and clerical worker households, groups such as professional, managerial and technical workers, the self-employed, short-term workers, the unemployed and retirees and others not in the labor force.

vi The Barclays U.S. TIPS Index represents an unmanaged market index made up of U.S. Treasury Inflation-Linked Index securities.

vii 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.

viii 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.

ix The Barclays U.S. Corporate High Yield — 2% Issuer Cap Index is an index of the 2% Issuer Cap component of the Barclays U.S. Corporate High Yield Index, which covers the U.S. dollar-denominated, non-investment grade, fixed-rate, taxable corporate bond market.

x The JPMorgan Emerging Markets Bond Index Global (“EMBI Global”) tracks total returns for U.S. dollar-denominated debt instruments issued by emerging market sovereign and quasi-sovereign entities: Brady bonds, loans, Eurobonds and local market instruments.

xi 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 net assets) 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.

xii Lipper, Inc., a wholly-owned subsidiary of Reuters, provides independent insight on global collective investments. Returns are based on the six-month period ended June 30, 2013, including the reinvestment of all distributions, including returns of capital, if any, calculated among the 14 funds in the Fund’s Lipper category.

Western Asset Inflation Management Fund Inc. 2013 Semi-Annual Report

Notes to financial statements (unaudited)

1. Organization and significant accounting policies

Western Asset Inflation Management Fund Inc. (the “Fund”) was incorporated in Maryland on March 16, 2004 and is registered as a non-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 total return. Current income is the Fund’s secondary investment objective.

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. Equity securities for which market quotations are available are valued at the last reported sales price or official closing price on the primary market or exchange on which they trade. When the Fund holds securities or other assets that are denominated in a foreign currency, the Fund will normally use the currency exchange rates as of 4:00 p.m. (Eastern Time). 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

Western Asset Inflation Management Fund Inc. 2013 Semi-Annual Report

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

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.

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.

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

† See Schedule of Investments for additional detailed categorizations.

(b) Repurchase agreements. The Fund may enter into repurchase agreements with institutions that its investment adviser has determined are creditworthy. Each repurchase agreement is recorded at cost. Under the terms of a typical repurchase agreement, the Fund acquires a debt security subject to an obligation of the seller to repurchase, and of the Fund to resell, the security at an agreed-upon price and time, thereby determining the yield during the Fund’s holding period. When entering into repurchase agreements, it is the Fund’s policy that its custodian or a third party custodian, acting on the Fund’s behalf, take possession of the underlying collateral securities, the market value of which, at all times, at least equals the principal amount of the repurchase transaction, including accrued interest. To the extent that any repurchase transaction maturity exceeds one business day, the value of the collateral is marked-to-market and measured against the value of the agreement in an effort to ensure the adequacy of the collateral. If the counterparty

Western Asset Inflation Management Fund Inc. 2013 Semi-Annual Report

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

defaults, the Fund generally has the right to use the collateral to satisfy the terms of the repurchase transaction. However, if the market value of the collateral declines during the period in which the Fund seeks to assert its rights or if bankruptcy proceedings are commenced with respect to the seller of the security, realization of the collateral by the Fund may be delayed or limited.

(c) Futures contracts. The Fund may use 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. For certain futures, including foreign denominated futures variation margin is not settled daily, but is recorded as a net variation margin payable or receivable. Futures contracts are valued daily at the settlement price established by the board of trade or exchange on which they are traded. 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.

(d) Written options. When the Fund writes an option, an amount equal to the premium received by the Fund is recorded as a liability, the value of which is marked-to-market daily to reflect the current market value of the option written. If the option expires, the premium received is recorded as a realized gain. When a written call option is exercised, the difference between the premium received plus the option exercise price and the Fund’s basis in the underlying security (in the case of a covered written call option), or the cost to purchase the underlying security (in the case of an uncovered written call option), including brokerage commission, is recognized as a realized gain or loss. When a written put option is exercised, the amount of the premium received is subtracted from the cost of the security purchased by the Fund from the exercise of the written put option to form the Fund’s basis in the underlying security purchased. The writer or buyer of an option traded on an exchange can liquidate the position before the exercise of the option by entering into a closing transaction. The cost of a closing transaction is deducted from the original premium received resulting in a realized gain or loss to the Fund.

The risk in writing a covered call option is that the Fund may forego the opportunity of profit if the market price of the underlying security increases and the option is exercised. The risk in writing a put option is that the Fund may incur a loss if the market price of the

Western Asset Inflation Management Fund Inc. 2013 Semi-Annual Report

underlying security decreases and the option is exercised. The risk in writing an uncovered call option is that the Fund is exposed to the risk of loss if the market price of the underlying security increases. 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.

(e) Forward foreign currency contracts. The Fund enters into a forward foreign currency contract to hedge against foreign currency exchange rate risk on its non-U.S. dollar denominated securities or to facilitate settlement of a foreign currency denominated portfolio transaction. A forward foreign currency contract is an agreement between two parties to buy and sell a currency at a set price with delivery and settlement at a future date. The contract is marked-to-market daily and the change in value is recorded by the Fund as an unrealized gain or loss. When a forward foreign currency contract is closed, through either delivery or offset by entering into another forward foreign currency contract, the Fund recognizes a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value of the contract at the time it is closed.

Forward foreign currency contracts involve elements of market risk in excess of the amounts reflected on the Statement of Assets and Liabilities. The Fund bears the risk of an unfavorable change in the foreign exchange rate underlying the forward foreign currency contract. Risks may also arise upon entering into these contracts from the potential inability of the counterparties to meet the terms of their contracts.

(f) Foreign currency translation. Investment securities and other assets and liabilities denominated in foreign currencies are translated into U.S. dollar amounts based upon prevailing exchange rates on the date of valuation. Purchases and sales of investment securities and income and expense items denominated in foreign currencies are translated into U.S. dollar amounts based upon prevailing exchange rates on the respective dates of such transactions.

The Fund does not isolate that portion of the results of operations resulting from fluctuations in foreign exchange rates on investments from the fluctuations arising from changes in market prices of securities held. Such fluctuations are included with the net realized and unrealized gain or loss on investments.

Net realized foreign exchange gains or losses arise from sales of foreign currencies, including gains and losses on forward foreign currency contracts, currency gains or losses realized between the trade and settlement dates on securities transactions, and the difference between the amounts of dividends, interest, and foreign withholding taxes recorded on the Fund’s books and the U.S. dollar equivalent of the amounts actually received or paid. Net unrealized foreign exchange gains and losses arise from changes in the values of assets and liabilities, other than investments in securities, on the date of valuation, resulting from changes in exchange rates.

Foreign security and currency transactions may involve certain considerations and risks not typically associated with those of U.S. dollar denominated transactions as a result of,

Western Asset Inflation Management Fund Inc. 2013 Semi-Annual Report

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

among other factors, the possibility of lower levels of governmental supervision and regulation of foreign securities markets and the possibility of political or economic instability.

(g) Inflation-indexed bonds. Inflation-indexed bonds are fixed-income securities whose principal value or interest rate is periodically adjusted according to the rate of inflation. As the index measuring inflation changes, the principal value or interest rate of inflation-indexed bonds will be adjusted accordingly. Repayment of the original bond principal upon maturity (as adjusted for inflation) is guaranteed in the case of U.S. Treasury inflation-indexed bonds. For bonds that do not provide a similar guarantee, the adjusted principal value of the bond repaid at maturity may be less than the original principal.

(h) Stripped securities. The Fund may invest in “Stripped Securities,” a term used collectively for components, or strips, of fixed income securities. Stripped securities can be principal only securities (“PO”), which are debt obligations that have been stripped of unmatured interest coupons, or interest only securities (“IO”), which are unmatured interest coupons that have been stripped from debt obligations. The market value of Stripped Securities will fluctuate in response to changes in economic conditions, rates of pre-payment, interest rates and the market’s perception of the securities. However, fluctuations in response to interest rates may be greater in Stripped Securities than for debt obligations of comparable maturities that pay interest currently. The amount of fluctuation may increase with a longer period of maturity.

The yield to maturity on IO’s is sensitive to the rate of principal repayments (including prepayments) on the related underlying debt obligation and principal payments may have a material effect on yield to maturity. If the underlying debt obligation experiences greater than anticipated prepayments of principal, the Fund may not fully recoup its initial investment in IO’s.

(i) Credit and market risk. The Fund invests in high-yield and emerging market instruments that are subject to certain credit and market risks. The yields of high-yield and emerging market debt 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. The consequences of political, social, economic or diplomatic changes may have disruptive effects on the market prices of investments held by the Fund. The Fund’s investments in non-U.S. dollar denominated securities may also result in foreign currency losses caused by devaluations and exchange rate fluctuations.

(j) Foreign investment risks. The Fund’s investments in foreign securities may involve risks not present in domestic investments. Since securities may be denominated in foreign currencies, may require settlement in foreign currencies or pay interest or dividends in foreign currencies, changes in the relationship of these foreign currencies to the U.S. dollar can significantly affect the value of the investments and earnings of the Fund. Foreign

Western Asset Inflation Management Fund Inc. 2013 Semi-Annual Report

investments may also subject the Fund to foreign government exchange restrictions, expropriation, taxation or other political, social or economic developments, all of which affect the market and/or credit risk of the investments.

(k) Counterparty risk and credit-risk-related contingent features of derivative instruments. The Fund may invest in certain securities or engage in other transactions, where the Fund is exposed to counterparty credit risk in addition to broader market risks. The Fund may invest in securities of issuers, which may also be considered counterparties as trading partners in other transactions. This may increase the risk of loss in the event of default or bankruptcy by the counterparty or if the counterparty otherwise fails to meet its contractual obligations. The Fund’s investment manager attempts to mitigate counterparty risk by (i) periodically assessing the creditworthiness of its trading partners, (ii) monitoring and/or limiting the amount of its net exposure to each individual counterparty based on its assessment and (iii) requiring collateral from the counterparty for certain transactions. Market events and changes in overall economic conditions may impact the assessment of such counterparty risk by the investment manager. In addition, declines in the values of underlying collateral received may expose the Fund to increased risk of loss.

The Fund has entered into master agreements with certain of its derivative counterparties that provide for general obligations, representations, agreements, collateral, events of default or termination and credit related contingent features. The credit related contingent features include, but are not limited to, a percentage decrease in the Fund’s net assets or NAV over a specified period of time. If these credit related contingent features were triggered, the derivatives counterparty could terminate the positions and demand payment or require additional collateral.

Collateral requirements differ by type of derivative. Collateral or margin requirements are set by the broker or exchange clearing house for exchange traded derivatives while collateral terms are contract specific for over-the-counter traded derivatives. Cash collateral that has been pledged to cover obligations of the Fund under derivative contracts, if any, will be reported separately in the Statement of Assets and Liabilities. Securities pledged as collateral, if any, for the same purpose are noted in the Schedule of Investments.

Absent an event of default by the counterparty or a termination of the agreement, the terms of the master agreements do not result in an offset of reported amounts of financial assets and financial liabilities in the Statement of Assets and Liabilities across transactions between the Fund and the applicable counterparty. The enforceability of the right to offset may vary by jurisdiction.

As of June 30, 2013, the Fund held forward foreign currency with credit related contingent features which had a liability position of $19,454. If a contingent feature in the master agreements would have been triggered, the Fund would have been required to pay this amount to its derivatives counterparties.

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

(l) 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. Dividend income is recorded on the ex-dividend date. 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.

(m) Distributions to shareholders. Distributions from net investment income of the Fund, if any, are declared 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 2013 fiscal year. Distributions of net realized gains, if any, 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.

(n) 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.

(o) 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 June 30, 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.

(p) 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. Western Asset Management Company (“Western Asset”), Western Asset Management Company Limited (“Western Asset Limited”) and Western Asset Management Company Pte. Ltd.

Western Asset Inflation Management Fund Inc.

Dividend reinvestment plan (unaudited)

Unless you elect to receive distributions in cash (i.e., opt-out), all distributions on your Common Shares will be automatically reinvested by American Stock Transfer and Trust Company, as agent for the Common Shareholders (the “Plan Agent”), in additional Common Shares under the 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 American Stock Transfer and Trust Company, as dividend paying agent.

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

(1) If the market price of the Common Shares on the record date (or, if the record date is not a New York Stock Exchange trading day, the immediately preceding trading day) for determining shareholders eligible to receive the relevant distribution (the “determination date”) is equal to or exceeds 98% of the net asset value per share of the Common Shares, the Fund will issue new Common Shares at a price equal to the greater of (a) 98% of the net asset value per share at the close of trading on the Exchange on the determination date or (b) 95% of the market price per share of the Common Shares on the determination date.

(2) If 98% of the net asset value per share of the Common Shares exceeds the market price of the Common Shares on the determination date, the Plan Agent will receive the dividend or distribution in cash and will buy Common Shares in the open market, on the Exchange or elsewhere, for your account as soon as practicable commencing on the trading day following the determination date and terminating no later than the earlier of (a) 30 days after the distribution payment date, or (b) the record date for the next succeeding distribution to be made to the Common Shareholders; except when necessary to comply with applicable provisions of the federal securities laws. If during this period: (i) the market price rises so that it equals or exceeds 98% of the net asset value per share of the Common Shares at the close of trading on the Exchange on the determination 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 Shares in the open market and the Fund shall issue the remaining Common Shares at a price per share equal to the greater of (a) 98% of the net asset value per share at the close of trading on the Exchange on the determination date or (b) 95% of the then current market price per share.

The Plan Agent maintains all participants’ accounts in the Plan and gives written confirmation of all transactions in the accounts, including information you may need for tax records. Common Shares in your account will be held by the Plan Agent in non-certificated form. Any proxy you receive will include all Common Shares you have received under the Plan.

Western Asset Inflation Management Fund Inc.

You may withdraw from the Plan by notifying the Plan Agent in writing at 6201 15th Avenue, Brooklyn, New York 11219 or by calling the Plan Agent at 1-888-888-0151 or by accessing the Plan Agent’s website at www.amstock.com. Such withdrawal will be effective immediately if notice is received by the Plan Agent not less than ten business days prior to any distribution record date; otherwise such withdrawal will be effective as soon as practicable after the Plan Agent’s investment of the most recently declared distribution on the Common Shares. The Plan may be terminated by the Fund upon notice in writing mailed to Common Shareholders at least 30 days prior to the record date for the payment of any distribution by the Fund for which the termination is to be effective. Upon any termination, you will be sent a certificate or certificates for the full Common Shares held for you under the Plan and cash for any fractional Common Shares. You may elect to notify the Plan Agent in advance of such termination to have the Plan Agent sell part or all of your shares on your behalf. You will be charged a service charge and the Plan Agent is authorized to deduct brokerage charges actually incurred for this transaction from the proceeds.

There is no service charge for reinvestment of your distributions in Common Shares. 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 Common Shares, this allows you to add to your investment through dollar cost averaging, which may lower the average cost of your Common Shares 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. Investors will be subject to income tax on amounts reinvested under the plan.

Automatically reinvesting distributions does not mean that you do not have to pay income taxes due upon receiving distributions.

The Fund reserves the right to amend or terminate the Plan if, in the judgment of the Board of Directors, the change is warranted. There is no direct service charge to participants in the Plan; however, the Fund reserves the right to amend the Plan to include a service charge payable by the participants. Additional information about the Plan and your account may be obtained from the Plan Agent at 1-888-888-0151.
