Investment commentary

Economic review

Economic activity in the U.S. was mixed during the twelve months ended December 31, 2018 (the “reporting period”). Looking back, the U.S. Department of Commerce reported that first quarter 2018 U.S. gross domestic product (“GDP”) ⁱ growth was 2.2%. GDP growth then accelerated to 4.2% during the second quarter of 2018 — the strongest reading since the third quarter of 2014. Third quarter 2018 GDP growth was 3.4%. The deceleration in GDP growth in the third quarter of 2018 reflected a downturn in exports and decelerations in nonresidential fixed investment and personal consumption expenditures. Imports increased in the third quarter after decreasing in the second. These movements were partly offset by an upturn in private inventory investment. Finally, the U.S. Department of Commerce’s initial reading for fourth quarter 2018 GDP growth was delayed due to the partial shutdown of the U.S. government.

Job growth in the U.S. was solid overall and supported the economy during the reporting period. As reported by the U.S. Department of Labor, when the reporting period ended on December 31, 2018, the unemployment rate was 3.9%, versus 4.1% when the period began. The percentage of longer-term unemployed also declined during the reporting period. In December 2018, 20.5% of Americans looking for a job had been out of work for more than six months, versus 21.5% when the period began.

The Federal Reserve Board (the “Fed”) ⁱⁱ continued tightening monetary policy during the reporting period, as it raised interest rates four times in 2018 and further reduced its balance sheet. As widely expected, the Fed raised the federal funds rate ⁱⁱⁱ at its meetings that ended on March 21, 2018 (to a range between 1.50% and 1.75%), June 13, 2018 (to a range between 1.75% and 2.00%), September 26, 2018 (to a range between 2.00% and 2.25%) and December 19, 2018 (to a range between 2.25% and 2.50%). At its meeting that concluded on January 30, 2019, after the reporting period ended, the Fed kept interest rates on hold and said, “In light of global economic and financial developments and muted inflation pressures, the Committee will be patient as it determines what future adjustments to the target range for the federal funds rate may be appropriate ….”

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

Sincerely,

Fund overview

Q. What is the Fund’s investment strategy?

A. The Fund’s primary investment objective is to provide current income. As a secondary investment objective, the Fund will seek capital appreciation. The Fund seeks to achieve its investment objectives by investing primarily in a diverse portfolio of mortgage-backed securities (“MBS”), consisting primarily of non-agency residential mortgage-backed securities (“RMBS”) and commercial mortgage-backed securities (“CMBS”).

The Fund intends to liquidate and distribute substantially all of the Fund’s net assets to shareholders on or about March 1, 2022.

The Fund also may invest, to a lesser degree, in other permitted investments, including cash and cash equivalents; Treasury securities; non-mortgage related asset-backed securities (“ABS”) backed by various asset classes including, but not limited to, small balance commercial mortgages, aircrafts, automobiles, credit cards, equipment, manufactured housing, franchises, recreational vehicles and student loans; and investment grade and below investment grade fixed income securities including bonds, debentures, notes, commercial paper and other similar types of debt instruments including hybrid securities. The Fund also may invest in any newly developed mortgage-related derivatives that may hereafter become available for mortgage investing.

The Fund may invest in derivative instruments, such as options contracts, futures contracts, options on futures contracts, indexed securities, credit linked notes, credit default swaps and other swap agreements for investment, hedging and risk management purposes with certain limitations. Notwithstanding the foregoing, the Fund may invest without limitation in Treasury futures, Eurodollar futures, interest rate swaps, swaptions or similar instruments and combinations thereof.

The Fund is not limited in its ability to invest in below investment grade (commonly referred to as “high yield” or “junk” securities) or illiquid securities. Below investment grade securities are securities rated below the Baa3 or BBB- categories at the time of purchase by one or more nationally recognized statistical rating organizations or unrated securities that we determined to be of comparable credit quality.

At Western Asset Management Company, LLC (formerly known as 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 S. Kenneth Leech, Greg E. Handler and Harris A. Trifon. Mr. Trifon has been part of the Fund’s portfolio management team since January 2019 and has been employed by Western Asset as an investment professional since 2014. From 2009 to 2014, Mr. Trifon worked as Director, Fixed Income Research at Deutsche Bank.


Western Asset Mortgage Defined Opportunity Fund Inc. 2018 Annual Report		1

Fund overview (cont’d)

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

A. Fixed income markets generally posted weak results over the twelve-month reporting period ended December 31, 2018. Spread sectors (non-Treasuries) experienced periods of elevated volatility as they were impacted by a number of factors, including generally solid economic growth in the U.S., moderating growth overseas, four interest rate hikes by the Federal Reserve Board (the “Fed”) ⁱ , concerns over a global trade war, geopolitical issues and, more recently, a partial shutdown of the U.S. government.

Both short- and long-term U.S. Treasury yields moved higher and the yield curve ⁱⁱ flattened during the reporting period. The yield for the two-year Treasury note began the reporting period at 1.89% — the low for the period — and ended the period at 2.48%. The high for the period of 2.98% occurred on November 8, 2018. The yield for the ten-year Treasury began the reporting period at 2.40% — the low for the period — and ended the period at 2.69%. The peak for the period of 3.24% took place on November 8, 2018.

The overall agency RMBS market posted a modest gain, but lagged equal-duration ⁱⁱⁱ Treasuries during the reporting period. This relative underperformance was partially driven by the Fed unwinding its balance sheet and paring its holdings of agency MBS. Interest rate volatility, especially during the fourth quarter of 2018, also negatively impacted the agency MBS market. In contrast, structured products, including non-agency RMBS, CMBS and ABS, generated solid results and outperformed equal duration Treasuries during the reporting period. Structured products in general were supported by overall positive fundamentals, solid consumer balance sheets and lending conditions that remained constrained.

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

A. A number of adjustments were made to the Fund during the reporting period. Within the non-agency RMBS market, we instituted a number of relative value trades by reducing the Fund’s exposure to holdings that performed well and exceeded our expectations, while investing in securities that we felt offered more attractive relative values. We also modestly added to the Fund’s position in credit risk transfer (“CRT”) securities issued by Freddie Mac and Fannie Mae.

In terms of the Fund’s position in CMBS, we increased the Fund’s exposure to shorter term floating rate new-issue single asset/single borrower commercial loans, while reducing its allocation to conduit (pooled) non-agency CMBS at the beginning of the fourth quarter of 2018, as spreads had tightened. We also reduced the Fund’s overall exposure to the ABS sector. More specifically, we increased the Fund’s positions in consumer loan ABS, while paring its allocation to rental car and student loan ABS.

During the reporting period, we utilized Treasury futures to manage the Fund’s duration and yield curve exposure. Overall, the use of these derivatives contributed to performance. CMBS index swaps (“CDS”), which were used to manage the Fund’s exposure to CMBS, were additive to results. The strategy also used foreign exchange forwards to manage currency risk. The use of this derivatives did not meaningfully impact performance.


2		Western Asset Mortgage Defined Opportunity Fund Inc. 2018 Annual Report

Finally, we actively utilized leverage in the Fund. When the reporting period began, the Fund’s leverage as a percentage of gross assets was roughly 31%. At the end of the period, approximately 31% of the Fund’s gross assets were levered. Overall, leverage contributed to results given the positive total return of the assets of the Fund in 2018.

Performance review

For the twelve months ended December 31, 2018, Western Asset Mortgage Defined Opportunity Fund Inc. returned 9.26% based on its net asset value (“NAV”) ^iv and -1.16% based on its New York Stock Exchange (“NYSE”) market price per share. The Fund’s unmanaged benchmark, the ICE BofAML U.S. Floating Rate Home Equity Loan Asset Backed Securities Index ^v , returned 2.29% for the same period. The Lipper U.S. Mortgage Closed-End Funds Category Average ^vi returned 3.12% over the same time frame. Please note that Lipper performance returns are based on each fund’s NAV.

During the twelve-month period, the Fund made distributions to shareholders totaling $3.86 per share*. The performance table shows the Fund’s twelve-month total return based on its NAV and market price as of December 31, 2018. Past performance is no guarantee of future results.

All figures represent past performance and are not a guarantee of future results.

** Total returns are based on changes in NAV or market price, respectively. Returns reflect the deduction of all Fund expenses, including management fees, operating expenses, and other Fund expenses. Returns do not reflect the deduction of brokerage commissions or taxes that investors may pay on distributions or the sale of shares.

† Total return assumes the reinvestment of all distributions at NAV.

‡ 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. On an absolute basis, the leading contributor to the Fund’s performance during the reporting period was our allocation to legacy non-agency RMBS (issued pre-2007). This sector continues to benefit from a favorable technical backdrop as the outstanding mount continued to run down. Our exposure to CTR securities issued by Fannie Mae and Freddie Mac also generated solid results. Elsewhere, within the CMBS market, new-issue single asset/single borrower securities were the most additive for returns. Finally, our allocation to ABS modestly contributed to performance.

Q. What were the leading detractors from performance?

A. The Fund generated a strong absolute return during the reporting period. Modestly detracting from absolute performance was the Fund’s cash position. While cash remained a small portion of the portfolio, it was a drag on relative performance given the upward trend in the marketplace during the reporting period.

*	For the tax character of distributions paid during the fiscal year ended December 31, 2018, please refer to page 42 of this report.

RISKS: The Fund is a non-diversified, limited-term closed-end management investment company designed primarily as a long-term investment and not as a trading vehicle. The Fund is not intended to be a complete investment program and, due to the uncertainty inherent in all investments, there can be no assurance that the Fund will achieve its investment 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. Because the Fund is non-diversified, it may be more susceptible to economic, political or regulatory events than a diversified fund. The Fund’s investments are subject to a number of risks, including credit risk, inflation risk and interest rate risk. As interest rates rise, bond prices fall, reducing the value of the Fund’s fixed-income holdings. The Fund may invest in lower-rated high-yield bonds (commonly known as “junk bonds”), which are subject to greater liquidity risk and credit risk (risk of default) than higher-rated obligations. Mortgage-backed securities are subject to additional risks, including prepayment risk, which can limit the potential gains in a declining interest rate environment. The Fund may invest in securities backed by subprime or distressed mortgages which involve a higher degree of risk and chance of loss. Leverage may result in greater volatility of NAV and the market price of common shares and increases a shareholder’s risk of loss. The Fund may make significant investments in derivative instruments. Derivative instruments can be illiquid, may disproportionately increase losses, and have a potentially large impact on Fund performance. The Fund is not guaranteed by the U.S. government, the U.S. Treasury or any government agency.

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.

Net asset value (“NAV”) is calculated by subtracting total liabilities, including liabilities associated with financial leverage (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.

The ICE BofAML U.S. Floating Rate Home Equity Loan Asset Backed Securities Index tracks the performance of U.S. dollar-denominated investment grade floating-rate asset-backed securities collateralized by home equity loans publicly issued in the U.S. domestic market. Qualifying securities must have an investment grade rating, at least one year remaining to final stated maturity, a floating-rate coupon, and an original deal size for the collateral group of at least $250 million.

Western Asset Mortgage Defined Opportunity Fund Inc. 2018 Annual Report		27

Notes to financial statements

1. Organization and significant accounting policies

Western Asset Mortgage Defined Opportunity Fund Inc. (the “Fund”) was incorporated in Maryland on December 11, 2009 and is registered as a non-diversified, limited-term, closed-end management investment company under the Investment Company Act of 1940, as amended (the “1940 Act”). The Fund’s primary investment objective is to provide current income. As a secondary investment objective, the Fund will seek capital appreciation. The Fund seeks to achieve its investment objectives by investing primarily in a diverse portfolio of mortgage-backed securities (“MBS”), consisting primarily of non-agency residential mortgage-backed securities (“RMBS”) and commercial mortgage-backed securities (“CMBS”). The Fund intends to liquidate and distribute substantially all of the Fund’s net assets to shareholders on or about March 1, 2022.

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. 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.


28		Western Asset Mortgage Defined Opportunity Fund Inc. 2018 Annual Report

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 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.)


Western Asset Mortgage Defined Opportunity Fund Inc. 2018 Annual Report		29

Notes to financial statements (cont’d)

•

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) 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. For certain futures, including foreign denominated futures, variation margin is not settled daily, but is recorded as a net variation margin payable or receivable. 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.


30		Western Asset Mortgage Defined Opportunity Fund Inc. 2018 Annual Report

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) Forward foreign currency contracts. The Fund enters into a forward foreign currency contract to hedge against, or manage exposure to, foreign issuers or markets. The Fund may also enter 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.

(d) Swap agreements. The Fund invests in swaps for the purpose of managing its exposure to interest rate, credit or market risk, or for other purposes, including to increase the Fund’s return. The use of swaps involves risks that are different from those associated with other portfolio transactions. Swap agreements are privately negotiated in the over-the-counter market and may be entered into as a bilateral contract (“OTC Swaps”) or centrally cleared (“Centrally Cleared Swaps”). Unlike Centrally Cleared Swaps, the Fund has credit exposure to the counterparties of OTC Swaps.

In a Centrally Cleared Swap, immediately following execution of the swap, the swap agreement is submitted to a clearinghouse or central counterparty (the “CCP”) and the CCP becomes the ultimate counterparty of the swap agreement. The Fund is required to interface with the CCP through a broker, acting in an agency capacity. All payments are settled with the CCP through the broker. Upon entering into a Centrally Cleared Swap, the Fund is required to deposit initial margin with the broker in the form of cash or securities.

Swap contracts are marked-to-market daily and changes in value are recorded as unrealized appreciation (depreciation). The daily change in valuation of Centrally Cleared Swaps, if any, is recorded as a receivable or payable for variation margin on the Statement of Assets and Liabilities. Gains or losses are realized upon termination of the swap agreement. Collateral, in the form of restricted cash or securities, may be required to be held in segregated accounts with the Fund’s custodian in compliance with the terms of the swap contracts. Securities posted as collateral for swap contracts are identified in the Schedule of


Western Asset Mortgage Defined Opportunity Fund Inc. 2018 Annual Report		31

Notes to financial statements (cont’d)

Investments and restricted cash, if any, is identified on the Statement of Assets and Liabilities. Risks may exceed amounts recorded in the Statement of Assets and Liabilities. These risks include changes in the returns of the underlying instruments, failure of the counterparties to perform under the contracts’ terms, and the possible lack of liquidity with respect to the swap agreements.

OTC swap payments received or made at the beginning of the measurement period are reflected as a premium or deposit, respectively, on the Statement of Assets and Liabilities. These upfront payments are amortized over the life of the swap and are recognized as realized gain or loss in the Statement of Operations. Net periodic payments received or paid by the Fund are recognized as a realized gain or loss in the Statement of Operations.

The Fund’s maximum exposure in the event of a defined credit event on a credit default swap to sell protection is the notional amount. As of December 31, 2018, the Fund did not hold any credit default swaps to sell protection.

For average notional amounts of swaps held during the year ended December 31, 2018, see Note 4.

Credit default swaps

The Fund enters into credit default swap (“CDS”) contracts for investment purposes, to manage its credit risk or to add leverage. CDS agreements involve one party making a stream of payments to another party in exchange for the right to receive a specified return in the event of a default by a third party, typically corporate or sovereign issuers, on a specified obligation, or in the event of a write-down, principal shortfall, interest shortfall or default of all or part of the referenced entities comprising a credit index. The Fund may use a CDS to provide protection against defaults of the issuers (i.e., to reduce risk where the Fund has exposure to an issuer) or to take an active long or short position with respect to the likelihood of a particular issuer’s default. As a seller of protection, the Fund generally receives an upfront payment or a stream of payments throughout the term of the swap provided that there is no credit event. If the Fund is a seller of protection and a credit event occurs, as defined under the terms of that particular swap agreement, the maximum potential amount of future payments (undiscounted) that the Fund could be required to make under a credit default swap agreement would be an amount equal to the notional amount of the agreement. These amounts of potential payments will be partially offset by any recovery of values from the respective referenced obligations. As a seller of protection, the Fund effectively adds leverage to its portfolio because, in addition to its total net assets, the Fund is subject to investment exposure on the notional amount of the swap. As a buyer of protection, the Fund generally receives an amount up to the notional value of the swap if a credit event occurs.

Implied spreads are the theoretical prices a lender receives for credit default protection. When spreads rise, market perceived credit risk rises and when spreads fall, market perceived credit risk falls. The implied credit spread of a particular referenced entity reflects the cost of buying/selling protection and may include upfront payments required to enter


32		Western Asset Mortgage Defined Opportunity Fund Inc. 2018 Annual Report

into the agreement. Wider credit spreads and decreasing market values, when compared to the notional amount of the swap, represent a deterioration of the referenced entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement. Credit spreads utilized in determining the period end market value of credit default swap agreements on corporate or sovereign issues are disclosed in the Schedule of Investments and serve as an indicator of the current status of the payment/performance risk and represent the likelihood or risk of default for credit derivatives. For credit default swap agreements on asset-backed securities and credit indices, the quoted market prices and resulting values, particularly in relation to the notional amount of the contract as well as the annual payment rate, serve as an indication of the current status of the payment/performance risk.

The Fund’s maximum risk of loss from counterparty risk, as the protection buyer, is the fair value of the contract (this risk is mitigated by the posting of collateral by the counterparty to the Fund to cover the Fund’s exposure to the counterparty). As the protection seller, the Fund’s maximum risk is the notional amount of the contract. Credit default swaps are considered to have credit risk-related contingent features since they require payment by the protection seller to the protection buyer upon the occurrence of a defined credit event.

Entering into a CDS agreement involves, to varying degrees, elements of credit, market and documentation risk in excess of the related amounts recognized on the Statement of Assets and Liabilities. Such risks involve the possibility that there will be no liquid market for these agreements, that the counterparty to the agreement may default on its obligation to perform or disagree as to the meaning of the contractual terms in the agreement, and that there will be unfavorable changes in net interest rates.

Total return swaps

The Fund enters into total return swaps for investment purposes. Total return swaps are agreements to exchange the return generated by one instrument for the return generated by another instrument. For example, the agreement to pay a predetermined or fixed interest rate in exchange for a market-linked return based on a notional amount. To the extent the total return of a referenced index or instrument exceeds the offsetting interest obligation, the Fund will receive a payment from the counterparty. To the extent it is less, the Fund will make a payment to the counterparty.

(e) Loan participations. The Fund may invest in loans arranged through private negotiation between one or more financial institutions. The Fund’s investment in any such loan may be in the form of a participation in or an assignment of the loan. In connection with purchasing participations, the Fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement related to the loan, or any rights of off-set against the borrower and the Fund may not benefit directly from any collateral supporting the loan in which it has purchased the participation.

The Fund assumes the credit risk of the borrower, the lender that is selling the participation and any other persons interpositioned between the Fund and the borrower. In the event of


Western Asset Mortgage Defined Opportunity Fund Inc. 2018 Annual Report		33

Notes to financial statements (cont’d)

the insolvency of the lender selling the participation, the Fund may be treated as a general creditor of the lender and may not benefit from any off-set between the lender and the borrower.

(f) 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.

(g) Mortgage-backed securities. Mortgage-Backed Securities (“MBS”) include CMBS and RMBS. These securities depend on payments (except for rights or other assets designed to assure the servicing or timely distribution of proceeds to holders of such securities) primarily from the cash flow from secured commercial or residential mortgage loans made to borrowers. Such loans are secured (on a first priority basis or second priority basis, subject to permitted liens, easements and other encumbrances) by commercial or residential real estate, the proceeds of which are used to purchase and or to construct commercial or residential real estate. The value of some mortgage-backed securities may be particularly sensitive to changes in prevailing interest rates. The value of these securities may fluctuate in response to the market’s perception of the creditworthiness of the issuers. Additionally, although certain mortgage-related securities are supported by some form of government or private guarantee and/or insurance, there is no assurance that private guarantors or insurers will meet their obligations.

(h) Leverage. The Fund may seek to enhance the level of its current distributions to holders of common stock through the use of leverage. The Fund may use leverage directly at the Fund level through borrowings, including loans from certain financial institutions or through a qualified government sponsored program, the use of reverse repurchase agreements and/or the issuance of debt securities (collectively, “Borrowings”), and possibly through the issuance of preferred stock (“Preferred Stock”), in an aggregate amount of up to approximately 33 1/3% of the Fund’s Total Assets immediately after such Borrowings and/or issuances of Preferred Stock. “Total Assets” means net assets of the Fund plus the amount of any Borrowings and assets attributable to Preferred Stock that may be outstanding. Currently, the Fund has no intention to issue notes or debt securities or Preferred Stock. In


34		Western Asset Mortgage Defined Opportunity Fund Inc. 2018 Annual Report

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

(i) 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.

(j) 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, 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.

(k) Credit and market risk. Investments in securities that are collateralized by real estate mortgages are subject to certain credit and liquidity risks. When market conditions result in an increase in default rates of the underlying mortgages and the foreclosure values of underlying real estate properties are materially below the outstanding amount of these underlying mortgages, collection of the full amount of accrued interest and principal on these investments may be doubtful. Such market conditions may significantly impair the value and liquidity of these investments and may result in a lack of correlation between their credit ratings and values.


Western Asset Mortgage Defined Opportunity Fund Inc. 2018 Annual Report		35

Notes to financial statements (cont’d)

(l) 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 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.

(m) 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 subadviser 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 subadviser. In addition, declines in the values of underlying collateral received may expose the Fund to increased risk of loss.

With exchange traded and centrally cleared derivatives, there is less counterparty risk to the Fund since the exchange or clearinghouse, as counterparty to such instruments, guarantees against a possible default. The clearinghouse stands between the buyer and the seller of the contract; therefore, the credit risk is limited to failure of the clearinghouse. While offset rights may exist under applicable law, the Fund does not have a contractual right of offset against a clearing broker or clearinghouse in the event of a default of the clearing broker or clearinghouse.

The Fund has entered into master agreements, such as an International Swaps and Derivatives Association, Inc. Master Agreement (“ISDA Master Agreement”) or similar agreement, with certain of its derivative counterparties that govern over-the-counter derivatives and provide for general obligations, representations, agreements, collateral posting terms, netting provisions in the event 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.

Under an ISDA Master Agreement, the Fund may, under certain circumstances, offset with the counterparty certain derivative financial instruments’ payables and/or receivables with collateral held and/or posted and create one single net payment. However, absent an event of default by the counterparty or a termination of the agreement, the terms of the ISDA


36		Western Asset Mortgage Defined Opportunity Fund Inc. 2018 Annual Report

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.

Collateral requirements differ by type of derivative. Collateral or margin requirements are set by the broker or exchange clearinghouse 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.

As of December 31, 2018, the Fund held forward foreign currency contracts with credit related contingent features which had a liability position of $1,206. 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.

(n) 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 Fund accretes market discounts and amortizes market premiums on debt securities using the effective yield method. Accretion of market discounts and amortization of market premiums requires the application of several assumptions including, but not limited to, prepayment assumptions and default rate assumptions, which are reevaluated not less than semi-annually and require the use of a significant amount of judgment. Principal write-offs are generally treated as realized losses. The Fund’s accretion of discounts and amortization of premiums for U.S. federal and other tax purposes is likely to differ from the financial accounting treatment under GAAP of these items as described above. Dividend income is recorded on the ex-dividend date for dividends received in cash and/or securities. 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.

(o) Partnership accounting policy. The Fund records its pro rata share of the income (loss) and capital gains (losses), to the extent of distributions it has received, allocated from the underlying partnerships and accordingly adjusts the cost basis of the underlying partnerships for return of capital. These amounts are included in the Fund’s Statement of Operations.

(p) Distributions to shareholders. Distributions from net investment income of the Fund, if any, are declared quarterly and paid on a monthly basis. 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.


Western Asset Mortgage Defined Opportunity Fund Inc. 2018 Annual Report		37

Notes to financial statements (cont’d)

(q) 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.

(r) 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. However, due to the timing of when distributions are made by the Fund, the Fund may be subject to an excise tax of 4% of the amount by which 98% of the Fund’s annual taxable income and 98.2% of net realized gains exceed the distributions from such taxable income and realized gains for the calendar year. The Fund accrued $14,000 of federal excise tax attributable to the calendar year 2017 during the year ended December 31, 2018.

Management has analyzed the Fund’s tax positions taken on income tax returns for all open tax years and has concluded that as of December 31, 2018, 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.

(s) 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. During the current year, the following reclassifications have been made:


	Total Distributable Earnings (Loss)		Paid-in Capital
(a)	$	14,000	$	(14,000)

^(a)	Reclassifications are due to a non-deductible excise tax accrued by the Fund.

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, LLC (formerly Western Asset Management Company) (“Western Asset”) and Western Asset Management Company Limited (“Western Asset Limited”) are the Fund’s subadvisers. LMPFA, Western Asset and Western Asset Limited are wholly-owned subsidiaries of Legg Mason, Inc. (“Legg Mason”).

Under the investment management agreement, the Fund pays an investment management fee, calculated daily and paid monthly, at an annual rate of 1.00% of the Fund’s average daily managed assets. Managed assets are net assets plus the proceeds of any outstanding borrowings used for leverage.

LMPFA provides administrative and certain oversight services to the Fund. LMPFA delegates to Western Asset the day-to-day portfolio management of the Fund. Western Asset Limited


38		Western Asset Mortgage Defined Opportunity Fund Inc. 2018 Annual Report

provides certain subadvisory services to the Fund relating to currency transactions and investments in non-U.S. dollar denominated debt securities. For its services, LMPFA pays Western Asset monthly 70% of the net management fee it receives from the Fund. In turn, Western Asset pays Western Asset Limited a monthly subadvisory fee in an amount equal to 100% of the management fee paid to Western Asset on the assets that Western Asset allocates to Western Asset Limited to manage.

During periods in which the Fund utilizes financial leverage, the fees paid to LMPFA will be higher than if the Fund did not utilize leverage because the fees are calculated as a percentage of the Fund’s assets, including those investments purchased with leverage.

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

3. Investments

During the year ended December 31, 2018, the aggregate cost of purchases and proceeds from sales of investments (excluding short-term investments) and U.S. Government & Agency Obligations were as follows:


	Investments		U.S. Government & Agency Obligations
Purchases	$	78,572,628	$	26,790,714
Sales		114,805,883		2,385,786

At December 31, 2018, the aggregate cost of investments and the aggregate gross unrealized appreciation and depreciation of investments for federal income tax purposes were as follows:


	Cost		Gross Unrealized Appreciation		Gross Unrealized Depreciation		Net Unrealized Appreciation (Depreciation)
Securities	$	315,676,748	$	13,232,322	$	(12,941,556)	$	290,766

5. Loan

Effective July 13, 2018, the Fund has a revolving credit agreement with Societe Generale (“Credit Agreement”) that allows the Fund to borrow up to an aggregate amount of $105,000,000. This Credit Agreement renews daily for a 150-day term unless notice to the contrary is given to the Fund, and has a scheduled maturity date of July 13, 2020. The Fund pays a commitment fee on the unutilized portion of the loan commitment amount at an annual rate of 0.60%, except that the commitment fee is 0.20% in the event that the aggregate outstanding principal balance of the loan is greater than 80% of $105,000,000. The interest on the loan is calculated at a variable rate based on the LIBOR, plus any applicable margin. Securities held by the Fund are subject to a lien, granted to Societe Generale, to the extent of the borrowing outstanding and any additional expenses. The Fund’s Credit Agreement contains customary covenants that, among other things, may limit the Fund’s ability to pay distributions in certain circumstances, incur additional debt, change its fundamental investment policies and engage in certain transactions, including mergers and consolidations, and require asset coverage ratios in addition to those required by the 1940 Act. In addition, the Credit Agreement may be subject to early termination under certain conditions and may contain other provisions that could limit the Fund’s ability to utilize borrowing under the agreement. Interest expense related to this loan for the year ended December 31, 2018 was $1,621,435. For the year ended December 31, 2018, related to the Credit Agreement, the Fund incurred commitment fees of $3,119. For the year ended December 31, 2018, based on the number of days during the reporting period that the Fund had an outstanding balance under the Credit Agreement, the Fund had an average daily loan balance outstanding of $101,735,465 and the weighted average interest rate was 3.38%. At December 31, 2018, the Fund had $99,250,000 of borrowings outstanding per this Credit Agreement.

Prior to July 13, 2018, the Fund had a revolving credit agreement with State Street Bank and Trust Company (“Prior Credit Agreement”) that allowed the Fund to borrow up to an aggregate amount of $120,000,000 and renewed daily for a 270-day term. The Prior Credit Agreement terminated on July 13, 2018 and was repaid directly by proceeds from the Credit Agreement. The Fund paid a commitment fee at annual rate of 0.25% on the unutilized portion of the loan commitment amount. The interest on the loan was calculated at a variable rate based on the LIBOR, plus any applicable margin. To the extent of the borrowing outstanding, the Fund was required to maintain collateral in a special custody account at the Fund’s custodian on behalf of State Street Bank and Trust Company. The Fund’s Prior Credit Agreement contained customary covenants that, among other things, may have limited the Fund’s ability to pay distributions in certain circumstances, incur additional debt, change its fundamental investment policies and engage in certain transactions, including mergers and consolidations, and required asset coverage ratios in addition to those required by the 1940 Act. In addition, the Prior Credit Agreement may have been subject to early termination under certain conditions and may have contained other provisions that could have limited the Fund’s ability to utilize borrowing under the agreement. Interest expense related to this loan for the period prior to July 13, 2018 was $1,494,092. For the period ended prior to July 13, 2018 the Fund incurred commitment fees in the amount of $24,466. For the period

7. 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 year ended December 31, 2018, the Fund did not repurchase any shares.

8. Income tax information and distributions to shareholders

The tax character of distributions paid during the fiscal years ended December 31, was as follows:


	2018		2017

Net long-term capital gains		5,123,644		4,336,667
Total distributions paid	$	40,408,500	$	34,270,428


42		Western Asset Mortgage Defined Opportunity Fund Inc. 2018 Annual Report

As of December 31, 2018, the components of accumulated earnings (losses) on a tax basis were as follows:


Undistributed ordinary income — net	$	5,856,023
Deferred capital losses*		(976,452)
Other book/tax temporary differences ^(a)		232,171
Unrealized appreciation (depreciation) ^(b)		(11,903)
Total accumulated earnings (losses) — net	$	5,099,839

*	These capital losses have been deferred in the current year as either short-term or long-term losses. The losses will be deemed to occur on the first day of the next taxable year in the same character as they were originally deferred and will be available to offset future taxable capital gains.

^(a)	Other book/tax temporary differences are attributable to the realization for tax purposes of unrealized gains (losses) on certain futures, foreign currency and swap contracts and book/tax differences in the timing of the deductibility of various expenses.

^(b)	The difference between book-basis and tax-basis unrealized appreciation (depreciation) is attributable to differences between the book and tax recognition of market discount and premiums on mortgage backed securities and book/tax differences in the treatment of partnership investments.

9. Recent accounting pronouncements

The Fund has adopted the disclosure provisions of Financial Accounting Standards Board Accounting Standards Update 2016-18 (“ASU 2016-18”), Statement of Cash Flows (Topic 230) — Restricted Cash . ASU 2016-18 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. ASU 2016-18 requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Prior to the issuance of ASU 2016-18, GAAP did not include specific guidance on the cash flow classification and presentation of changes in restricted cash or restricted cash equivalents. Upon evaluation, the Fund has concluded that ASU 2016-18 does not materially impact the financial statement amounts; however, as required, additional or enhanced disclosure has been included.

In August 2018, the Securities and Exchange Commission released its Final Rule on Disclosure Update and Simplification (the “Final Rule”) which is intended to simplify an issuer’s disclosure compliance efforts by removing redundant or outdated disclosure requirements without significantly altering the mix of information provided to investors. Effective with the current reporting period, the Fund adopted the Final Rule with the most notable impacts being that the Fund is no longer required to present the components of distributable earnings on the Statement of Assets and Liabilities or the sources of distributions to shareholders and the amount of undistributed net investment income on the Statements of Changes in Net Assets. The tax components of distributable earnings and distributions to shareholders continue to be disclosed within the Notes to Financial Statements.

Board approval of management and subadvisory agreements (unaudited)

Background

The Investment Company Act of 1940, as amended (the “1940 Act”), requires that the Board of Directors (the “Board”) of Western Asset Mortgage Defined Opportunity Fund Inc. (the “Fund”), including a majority of its members who are not considered to be “interested persons” under the 1940 Act (the “Independent Directors”) voting separately, approve on an annual basis the continuation of the investment management contract (the “Management Agreement”) with the Fund’s manager, Legg Mason Partners Fund Advisor, LLC (the “Manager”), and the sub-advisory agreements (individually, a “Sub-Advisory Agreement,” and collectively, the “Sub-Advisory Agreements”) with the Manager’s affiliates, Western Asset Management Company, LLC (“Western Asset”) and Western Asset Management Company Limited in London (“Western Asset London,” and together with Western Asset, the “Sub-Advisers”). At a meeting (the “Contract Renewal Meeting”) held in-person on November 7 and 8, 2018, the Board, including the Independent Directors, considered and approved the continuation of each of the Management Agreement and the Sub-Advisory Agreements for an additional one-year term. To assist in its consideration of the renewals of the Management Agreement and the Sub-Advisory Agreements, the Board received and considered a variety of information (together with the information provided at the Contract Renewal Meeting, the “Contract Renewal Information”) about the Manager and the Sub-Advisers, as well as the management and sub-advisory arrangements for the Fund and the other closed-end funds in the same complex under the Board’s supervision (the “Legg Mason Closed-end Funds”), certain portions of which are discussed below. A presentation made by the Manager and Western Asset to the Board at the Contract Renewal Meeting in connection with its evaluations of the Management Agreement and the Sub-Advisory Agreements encompassed the Fund and other Legg Mason Closed-end Funds. In addition to the Contract Renewal Information, the Board received performance and other information throughout the year related to the respective services rendered by the Manager and the Sub-Advisers to the Fund. The Board’s evaluation took into account the information received throughout the year and also reflected the knowledge and familiarity gained as members of the Boards of the Fund and other Legg Mason Closed-end Funds with respect to the services provided to the Fund by the Manager and the Sub-Advisers.

At a meeting held by conference call on October 31, 2018, the Independent Directors in preparation for the Contract Renewal Meeting met in a private session with their independent counsel to review Contract Renewal Information in respect of the Legg Mason Closed-end Funds, including the Fund, received to date. No representatives of the Manager or the Sub-Adviser participated in this meeting. The discussion below reflects all of these reviews.

The Manager provides the Fund with investment advisory and administrative services pursuant to the Management Agreement and the Sub-Advisers together provide the Fund with certain investment sub-advisory services pursuant to the Sub-Advisory Agreements. The discussion below covers both the advisory and administrative functions being rendered by


Western Asset Mortgage Defined Opportunity Fund Inc.		45

Board approval of management and subadvisory agreements (unaudited) (cont’d)

the Manager, each such function being encompassed by the Management Agreement, and the investment sub-advisory functions being rendered by the Sub-Advisers.

Board approval of management agreement and sub-advisory agreements

In its deliberations regarding renewal of the Management Agreement and the Sub-Advisory Agreements, the Board, including the Independent Directors, considered the factors below.

Nature, extent and quality of the services under the management agreement and sub-advisory agreements

The Board received and considered Contract Renewal Information regarding the nature, extent, and quality of services provided to the Fund by the Manager and the Sub-Advisers under the Management Agreement and the Sub-Advisory Agreements, respectively, during the past year. The Board also reviewed Contract Renewal Information regarding the Fund’s compliance policies and procedures established pursuant to the 1940 Act.

The Board reviewed the qualifications, backgrounds, and responsibilities of the Fund’s senior personnel and the portfolio management team primarily responsible for the day-to-day portfolio management of the Fund. The Board also considered, based on its knowledge of the Manager and its affiliates, the Contract Renewal Information and the Board’s discussions with the Manager and Western Asset at the Contract Renewal Meeting, the general reputation and investment performance records of the Manager, Western Asset and their affiliates and the financial resources available to the corporate parent of the Manager and the Sub-Advisers, Legg Mason, Inc. (“Legg Mason”), to support their activities in respect of the Fund and the other Legg Mason Closed-end Funds.

The Board considered the responsibilities of the Manager and the Sub-Advisers under the Management Agreement and the Sub-Advisory Agreements, respectively, including the Manager’s coordination and oversight of the services provided to the Fund by the Sub-Advisers and others and Western Asset’s coordination and oversight of the services provided to the Fund by Western Asset London. The Management Agreement permits the Manager to delegate certain of its responsibilities, including its investment advisory duties thereunder, provided that the Manager, in each case, will supervise the activities of the delegee. Pursuant to this provision of the Management Agreement, the Manager does not provide day-to-day portfolio management services to the Fund. Rather, portfolio management services for the Fund are provided by Western Asset pursuant to the Sub-Advisory Agreement (the “Western Asset Sub-Advisory Agreement”) between the Manager and Western Asset. The Western Asset Sub-Advisory Agreement permits Western Asset to delegate certain of its responsibilities, including its investment sub-advisory duties thereunder, provided that Western Asset, in each case, will supervise the activities of the delegee. Pursuant to this provision of the Western Asset Sub-Advisory Agreement, Western Asset London helps Western Asset to provide portfolio management services to the Fund pursuant to a separate Sub-Advisory Agreement between Western Asset and Western Asset London.


46		Western Asset Mortgage Defined Opportunity Fund Inc.

In reaching its determinations regarding continuation of the Management Agreement and the Sub-Advisory Agreements, the Board took into account that Fund shareholders, in pursuing their investment goals and objectives, likely purchased their shares based upon the reputation and the investment style, philosophy and strategy of the Manager and Western Asset, as well as the resources available to the Manager and the Sub-Advisers.

The Board concluded that, overall, the nature, extent, and quality of the management and other services provided to the Fund under the Management Agreement and the Sub-Advisory Agreements have been satisfactory under the circumstances.

Fund performance

The Board received and considered information regarding Fund performance, including information and analyses (the “Broadridge Performance Information”) for the Fund, as well as for a group of comparable funds (the “Performance Universe”) selected by Broadridge Financial Solutions, Inc. (“Broadridge”), an independent provider of investment company data. The Board was provided with a description of the methodology Broadridge used to determine the similarity of the Fund with the funds included in the Performance Universe. The Performance Universe included the Fund and all other leveraged U.S. mortgage closed-end funds, as classified by Broadridge, regardless of asset size. The Performance Universe consisted of five funds, including the Fund, for each of the 1-, 3-, and 5-year periods ended June 30, 2018. The Board noted that it had received and discussed with the Manager and Western Asset information throughout the year at periodic intervals comparing the Fund’s performance against its benchmark and its peer funds as selected by Broadridge.

The Broadridge Performance Information comparing the Fund’s performance to that of the Performance Universe based on net asset value per share showed, among other things, that among the funds in the performance Universe, the Fund’s performance was ranked first (first being best in these performance rankings) for each of the 1-, 3-, and 5-year periods ended June 30, 2018 and was better than the Performance Universe median for each of those periods. In reviewing the Fund’s performance relative to the Performance Universe, the Board noted that the small number of funds comprising the Performance Universe made meaningful performance comparisons difficult. In addition to the Fund’s performance relative to the Performance Universe, the Board considered the Fund’s performance in absolute terms and the Fund’s performance relative to its benchmark. On a net asset value basis, the Fund outperformed its benchmark for each of the 1-, 3-, and 5-year periods ended June 30, 2018.

Based on the reviews and discussions of Fund performance and considering other relevant factors, including those noted above, the Board concluded, under the circumstances, that continuation of the Management Agreement and the Sub-Advisory Agreements for an additional one-year period would be consistent with the interests of the Fund and its shareholders.

Management fees and expense ratios

The Board reviewed and considered the management fee (the “Management Fee”) payable by the Fund to the Manager under the Management Agreement and the sub-advisory fees (the “Sub-Advisory Fees”) payable to the Sub-Advisers under the Sub-Advisory Agreements in light of the nature, extent and overall quality of the management, investment advisory and other services provided by the Manager and the Sub-Advisers. The Board noted that the Sub-Advisory Fee payable to Western Asset under the Western Asset Sub-Advisory Agreement is paid by the Manager, not the Fund, and, accordingly, that the retention of Western Asset does not increase the fees or expenses otherwise incurred by the Fund’s shareholders. Similarly, the Board noted that the Sub-Advisory Fee payable to Western Asset London under its Sub-Advisory Agreement with Western Asset is paid by Western Asset, not the Fund, and, accordingly, that the retention of Western Asset London does not increase the fees or expenses otherwise incurred by the Fund’s shareholders.

Additionally, the Board received and considered information and analyses prepared by Broadridge (the “Broadridge Expense Information”) comparing the Management Fee and the Fund’s overall expenses with those of funds in an expense universe (the “Expense Universe”) selected and provided by Broadridge. The comparison was based upon the constituent funds’ latest fiscal years. The Expense Universe consisted of the Fund and four other leveraged U.S. mortgage closed-end funds, as classified by Broadridge. The five funds in the Expense Universe had average net common share assets ranging from $76.8 million to $433.8 million. Two of the other Expense Universe funds were larger than the Fund and two were smaller.

The Broadridge Expense Information, comparing the Management Fee as well as the Fund’s actual total expenses to the Fund’s Expense Group, showed, among other things, that the Management Fee on a contractual basis was ranked third (first being lowest and, therefore, best in these expense component rankings) among the five funds in the Expense Group and was at the Expense Universe median for that expense component. Among the Expense Universe funds, the Fund’s actual Management Fee (i.e., giving effect to any voluntary fee waivers implemented by the Manager with respect to the Fund and by the managers of the other Expense Universe funds) was ranked third whether compared on the basis of common share assets only or on the basis of common share and leveraged assets and, in each case, was at the Expense Universe median for that expense component. The Broadridge Expense Information further showed that the Fund’s actual total expenses ranked fourth among the Expense Universe funds when compared on the basis of common share assets only and were ranked third when compared on the basis of common share and leveraged assets than the Expense Group median for that expense component. The Fund’s total expenses, on the basis of common share assets only, were lower than the Expense Group Median for that expense component and, on the basis of common share and leveraged assets, were at the Expense Group Median for that expense component. With respect to the Fund’s actual total expenses, the Manager noted, among other things, that the Fund’s investment-related expenses were higher than those of the other Expense Group funds whether compared on


48		Western Asset Mortgage Defined Opportunity Fund Inc.

the basis of common share assets only or on the basis of common share and leveraged assets, and that the total expenses for the Fund also were increased by its election to pay an excise tax on undistributed earnings rather than make a special distribution. The Manager noted further that the small number, varying sizes and differing investment strategies of funds comprising the Expense Group made meaningful expense comparisons difficult. Three of the four other Expense Universe funds were managed by the same manager.

The Board also reviewed Contract Renewal Information regarding fees charged by the Manager to other U.S. clients investing primarily in an asset class similar to that of the Fund, including, where applicable, institutional and separate accounts. The Board was advised that the fees paid by such institutional, separate account and other clients (collectively, “institutional clients”) generally are lower, and may be significantly lower, than the Management Fee. The Contract Renewal Information discussed the significant differences in scope of services provided to the Fund and to institutional clients. Among other things, institutional clients have fewer compliance, administration and other needs than the Fund and the Fund is subject not only to heightened regulatory requirements relative to institutional clients but also to requirements for listing on the New York Stock Exchange. The Contract Renewal Information noted further that the Fund is provided with administrative services, office facilities, Fund officers (including the Fund’s chief executive, chief financial and chief compliance officers), and that the Manager coordinates and oversees the provision of services to the Fund by other fund service providers. The Contract Renewal Information included information regarding management fees paid by open-end mutual funds in the same complex (the “Legg Mason Open-end Funds”) and such information indicated that the management fees paid by the Legg Mason Closed-end Funds generally were higher than those paid by the Legg Mason Open-end Funds. The Manager, in response to an inquiry from the Board as to the reasons for the fee differential, provided information as to differences between the services provided to the Fund and the other Legg Mason Closed-end Funds and the services provided to the Legg Mason Open-end Funds. The Board considered the fee comparisons in light of the different services provided in managing these other types of clients and funds.

Taking all of the above into consideration, the Board determined that the Management Fee and the Sub-Advisory Fees were reasonable in light of the nature, extent and overall quality of the management, investment advisory and other services provided to the Fund under the Management Agreement and the Sub-Advisory Agreements.

Manager profitability

The Board, as part of the Contract Renewal Information, received an analysis of the profitability to the Manager and its affiliates in providing services to the Fund for the Manager’s fiscal years ended March 31, 2018 and March 31, 2017. The Board also received profitability information with respect to the Legg Mason fund complex as a whole. In addition, the Board received Contract Renewal Information with respect to the Manager’s revenue and cost allocation methodologies used in preparing such profitability data. The profitability


Western Asset Mortgage Defined Opportunity Fund Inc.		49

Board approval of management and subadvisory agreements (unaudited) (cont’d)

to each of the Sub-Advisers was not considered to be a material factor in the Board’s considerations since Western Asset’s Sub-Advisory Fee is paid by the Manager, not the Fund, and the Sub-Advisory Fee for Western Asset London is paid by Western Asset, not the Fund. The profitability analysis presented to the Board as part of the Contract Renewal Information indicated that profitability to the Manager decreased during the period covered by the analysis and remained at a level that the Board did not consider to be excessive in light of judicial guidance and the nature, extent and overall quality of the investment advisory and other services provided to the Fund. However, the Board determined that profitability to the Manager in providing services to the Fund continued to merit continuing monitoring at its current level.

Economies of scale

The Board received and discussed Contract Renewal Information concerning whether the Manager realizes economies of scale if the Fund’s assets grow. The Board noted that because the Fund is a closed-end fund with no current plans to seek additional assets beyond maintaining its dividend reinvestment plan, any significant growth in its assets generally will occur through appreciation in the value of the Fund’s investment portfolio, rather than sales of additional shares in the Fund. The Board determined that the Management Fee structure, which incorporates no breakpoints reducing the Management Fee at specified increased asset levels, was appropriate under present circumstances.

Other benefits to the manager and the sub-advisers

The Board considered other benefits received by the Manager, the Sub-Advisers and their affiliates as a result of their relationship with the Fund and did not regard such benefits as excessive.

* * * * * *

In light of all of the foregoing and other relevant factors, the Board determined, under the circumstances, that continuation of the Management Agreement and the Sub-Advisory Agreements would be consistent with the interests of the Fund and its shareholders and unanimously voted to continue each Agreement for a period of one additional year. No single factor reviewed by the Board was identified by the Board as the principal factor in determining whether to approve continuation of the Management Agreement and the Sub-Advisory Agreements, and each Board member may have attributed different weights to the various factors. The Independent Directors were advised by separate independent legal counsel throughout the process. Prior to the Contract Renewal Meeting, the Board received a memorandum prepared by the Manager discussing its responsibilities in connection with the proposed continuation of the Management Agreement and the Sub-Advisory Agreements as part of the Contract Renewal Information and the Independent Directors separately received a memorandum discussing such responsibilities from their independent counsel. Prior to voting, the Independent Directors also discussed the proposed continuation of the Management Agreement and the Sub-Advisory Agreements in private sessions with their independent legal counsel at which no representatives of the Manager or any Sub-Adviser were present.

Dividend reinvestment plan (unaudited)

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

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

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

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

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


Western Asset Mortgage Defined Opportunity Fund Inc.		59

Dividend reinvestment plan (unaudited) (cont’d)

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 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.

(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.

Pre-approval by the Committee of any permissible non-audit services is not required so long as: (i) the aggregate amount of all such permissible non-audit services provided to the Fund, the Adviser and any service providers controlling, controlled by or under common control with the Adviser that provide ongoing services to the Fund (“Covered Service Providers”) constitutes not more than 5% of the total amount of revenues paid to the independent auditors during the fiscal year in which the permissible non-audit services are provided to (a) the Fund, (b) the Adviser and (c) any entity controlling, controlled by or under common control with the Adviser that provides ongoing services to the Fund during the fiscal year in which the services are provided that would have to be approved by the Committee; (ii) the permissible non-audit services were not recognized by the Fund at the time of the engagement to be non-audit services; and (iii) such services are promptly brought to the attention of the Committee and approved by the Committee (or its delegate(s)) prior to the completion of the audit.

(h) Yes. Western Asset Mortgage Defined Opportunity Fund Inc.’s Audit Committee has considered whether the provision of non-audit services that were rendered to Service Affiliates, which were not pre-approved (not requiring pre-approval), is compatible with maintaining the Accountant’s independence.

DISCLOSURE OF PROXY VOTING POLOCIES AND PROCEDURES FOR CLOSED-END MANAGEMENT INVESTMENT COMPANIES

Western Asset Management Company, LLC

Proxy Voting Policies and Procedures

BACKGROUND

An investment adviser is required to adopt and implement policies and procedures that we believe are reasonably designed to ensure that proxies are voted in the best interest of clients, in accordance with fiduciary duties and SEC Rule 206(4)-6 under the Investment Advisers Act of 1940 (“Advisers Act”). The authority to vote the proxies of our clients is established through investment management agreements or comparable documents. In addition to SEC requirements governing advisers, long-standing fiduciary standards and responsibilities have been established 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.

POLICY

As a fixed income only manager, the occasion to vote proxies is very rare. However, the Firm has 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”). 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.

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 the Firm’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 the Firm deems appropriate).

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 (other than Western Asset affiliated companies) regarding the voting of any securities owned by its clients.

PROCEDURE

Responsibility and Oversight

The Western Asset Legal and Compliance Department (“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 the 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

Western Asset’s proxy policies are described in the firm’s Part 2A of Form ADV. 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 (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 or an officer or director of Western 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.

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:

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.

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.

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.

Matters relating to Acquisitions, Mergers, Reorganizations and Other Transactions

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

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.

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:

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

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

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.

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.

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.

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

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

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.

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.

Western Asset Management Company Limited

Proxy Voting and Corporate Actions Policy

NOTE: Below policy relating to Proxy Voting and Corporate Actions is a global policy for all Western Asset affiliates. As compliance with the Policy is monitored by Western Asset Pasadena affiliate, the Policy has been adopted from US Compliance Manual and therefore all defined terms are those defined in the US Compliance Manual rather than UK Compliance Manual.

As a fixed income only manager, the occasion to vote proxies is very rare. However, the Firm has 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”). 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.

Voting Shares of Foreign Issuers

In the event WAMJ 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.

WAMJ votes for shareholder proposals calling for a majority of the directors to be independent of management.

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

WAMJ 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.

Western Asset Management Company Pte. Ltd. (“WAMS”)

Compliance Policies and Procedures

Proxy Voting

WAMS has 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 the applicable laws and regulations. In addition to SEC requirements governing advisers, our proxy voting policies reflect the long standing fiduciary standards and responsibilities for ERISA accounts.

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 the Firm’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 the Firm deems appropriate).

In exercising its voting authority, WAMS will not consult or enter into agreements with officers, directors or employees of Legg Mason Inc. or any of its affiliates (other than Western Asset affiliated companies) regarding the voting of any securities owned by its clients.

Procedure

Responsibility and Oversight

The Western Asset 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 and portfolio managers are determining appropriate voting positions on each proxy utilizing any applicable guidelines contained in these procedures.

Client 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 Recipients 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 to 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, (4.1) 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 (4.2) 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 votes the proxy pursuant to the instructions received in (4) or (5) and returns the voted proxy as indicated in the proxy materials.

Timing

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 plan for five years, the first two in Western Asset’s offices.

Disclosure

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

•

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

Guidelines are grouped according to the types of proposals generally presented to shareholders. Part 1 deals with proposals which have been approved and are recommended by a company’s board of directors; Part 2 deals with proposals submitted by shareholders for inclusion in proxy statements; Part 3 addresses issues relating to voting shares of investment companies; and Part 4 addresses unique considerations pertaining to foreign issuers.

Part 1 Board Approved Proposals

The vast majority of matters presented to shareholders for a vote involve proposals made by a comp any 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:

•

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 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.

•

Matters relating to Executive Compensation.

•

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 re-pricing 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.

•

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 circumstance 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.

•

Matters relating to Acquisitions, Mergers, Reorganizations and Other Transactions. Western Asset votes these issues on a case-by-case basis on board-approved transactions.

•

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 right plans.

•

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

•

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.

Part 2 Shareholder Proposals SEC regulations permit shareholders to submit proposals for inclusion in a company’s proxy voting statement. These proposals generally seek to change some aspect of a company’s corporate governance structure or to changes 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:

•

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

•

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

•

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.

Part 3 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 1 and 2 above are voted in accordance with those guidelines.

•

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.

Part 4 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 disclosure foreign issuers and therefore apply only where applicable.

•

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

•

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

•

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 pre-emptive rights, or (2) the issuance of common stock in excess of 100% of a company’s outstanding common stock where shareholders have pre-emptive rights.

Retirement Accounts

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: (1) the right to vote proxies has been reserved to a named fiduciary of the client, and (2) 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.

‡ The numbers above reflect the overall number of portfolios managed by employees of Western Asset Management Company (“Western Asset”). Mr. Leech 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. He is 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

The subadviser has adopted compliance policies and procedures to address a wide range of potential conflicts of interest that could directly impact client portfolios. For example, potential conflicts of interest may arise in connection with the management of multiple portfolios (including portfolios managed in a personal capacity). These could include potential conflicts of interest related to the knowledge and timing of a portfolio’s trades, investment opportunities and broker selection. Portfolio managers are privy to the size, timing, and possible market impact of a portfolio’s trades.

It is possible that an investment opportunity may be suitable for both a portfolio and other accounts managed by a portfolio manager, but may not be available in sufficient quantities for both the portfolio and the other accounts to participate fully. Similarly, there may be limited opportunity to sell an investment held by a portfolio and another account. A conflict may arise where the portfolio manager may have an incentive

to treat an account preferentially as compared to a portfolio because the account pays a performance-based fee or the portfolio manager, the subadviser or an affiliate has an interest in the account. The subadviser has adopted procedures for allocation of portfolio transactions and investment opportunities across multiple client accounts on a fair and equitable basis over time. Eligible accounts that can participate in a trade generally share the same price on a pro-rata allocation basis, taking into account differences based on factors such as cash availability, investment restrictions and guidelines, and portfolio composition versus strategy.

With respect to securities transactions, the subadviser determines which broker or dealer to use to execute each order, consistent with their duty to seek best execution of the transaction. However, with respect to certain other accounts (such as pooled investment vehicles that are not registered investment companies and other accounts managed for organizations and individuals), the subadviser may be limited by the client with respect to the selection of brokers or dealers or may be instructed to direct trades through a particular broker or dealer. In these cases, trades for a portfolio in a particular security may be placed separately from, rather than aggregated with, such other accounts. Having separate transactions with respect to a security may temporarily affect the market price of the security or the execution of the transaction, or both, to the possible detriment of a portfolio or the other account(s) involved. Additionally, the management of multiple portfolios and/or other accounts may result in a portfolio manager devoting unequal time and attention to the management of each portfolio and/or other account. The subadviser’s team approach to portfolio management and block trading approach seeks to limit this potential risk.

The subadviser also maintains a gift and entertainment policy to address the potential for a business contact to give gifts or host entertainment events that may influence the business judgment of an employee. Employees are permitted to retain gifts of only a nominal value and are required to make reimbursement for entertainment events above a certain value. All gifts (except those of a de minimis value) and entertainment events that are given or sponsored by a business contact are required to be reported in a gift and entertainment log which is reviewed on a regular basis for possible issues.

Employees of the subadviser have access to transactions and holdings information regarding client accounts and the subadviser’s overall trading activities. This information represents a potential conflict of interest because employees may take advantage of this information as they trade in their personal accounts. Accordingly, the subadviser maintains a Code of Ethics that is compliant with Rule 17j-1 under the Investment Company Act of 1940, as amended, and Rule 204A-1 under the Investment Advisers Act of 1940, to address personal trading. In addition, the Code of Ethics seeks to establish broader principles of good conduct and fiduciary responsibility in all aspects of the subadviser’s business. The Code of Ethics is administered by the Legal and Compliance Department and monitored through the subadviser’s compliance monitoring program.

The subadviser may also face other potential conflicts of interest with respect to managing client assets, and the description above is not a complete description of every conflict of interest that could be deemed to exist. The subadviser also maintains a compliance monitoring program and engages independent auditors to conduct a SOC1/ISAE 3402 audit on an annual basis. These steps help to ensure that potential conflicts of interest have been addressed.

CODE OF ETHICS

I. Introduction

A. Individuals Covered by the Code

This Code applies to all employees of Legg Mason & Co., LLC and interested directors of the Proprietary Funds who are not otherwise subject to another code of ethics adopted pursuant to either Rule 17j-1 under the Investment Company Act or Rule 204A-1 under the Investment Advisers Act (“Covered Persons”).

1.	Without limiting the generality of the foregoing, this Code covers all employees of Legg Mason & Co., LLC who perform services on behalf of the Proprietary Funds as part of the following regulated entities:

a.	Legg Mason Investor Services, LLC (“LMIS”).

b.	Legg Mason Partners Fund Advisor, LLC (“LMPFA”).

For the avoidance of doubt, each of the Legg Mason Registered Advisers (other than LMPFA) have adopted their own codes of ethics, and employees of the Legg Mason Registered Advisers who are subject to the requirements of those codes of ethics (including any who may be registered representatives of LMIS) are not subject to the requirements of this Code.

B. Standards of Business Conduct

This Code is based on the principle that Legg Mason and its affiliates owe a fiduciary duty to Legg Mason’s clients, and that all Covered Persons must therefore avoid activities, interests and relationships that might (i) present a conflict of interest or the appearance of a conflict of interest, or (ii) otherwise interfere with Legg Mason’s ability to make decisions in the best interests of any of its clients. In particular, Covered Persons must at all times comply with the following standards of business conduct:

1.	Compliance with Applicable Law. All Covered Persons must comply with the Federal Securities Laws that apply to the business of Legg Mason.

Clients Come First. Covered Persons must scrupulously avoid serving their personal interests ahead of the interests of clients. For example, a Covered Person may not induce or cause a client to take action, or not to take action, for the Covered Person’s personal benefit at the expense of the client’s best interests.

3.	Avoid Taking Advantage. Covered Persons may not use their knowledge of the Legg Mason Registered Advisers’ investment activities or client portfolio holdings to profit by the market effect of such activities or to engage in short-term or other abusive trading in Reportable Funds.

Avoid Other Inappropriate Relationships or Activities. Covered Persons should avoid relationships or activities that could call into question the Covered Person’s ability to exercise independent judgment in the best interests of Legg Mason’s clients. In particular, Covered Persons should take note of the provisions of the Legg Mason Code of Conduct and the Legg Mason Employee Handbook that pertain to confidentiality, corporate opportunities, gifts and entertainment, insider trading and outside business activities. In addition, Covered Persons who are registered representatives of LMIS should also take note of LMIS’s policies and procedures pertaining to these activities.

Observe the Spirit of the Code. Doubtful situations should be resolved in favor of Legg Mason’s clients. Technical compliance with the Code’s procedures will not automatically insulate from scrutiny any personal Securities Transactions or other course of conduct that might indicate an abuse of these governing principles.

C. Duty to Report Violations

Covered Persons must promptly report all violations of this Code to the Compliance Department.

D. Fiduciary Duty / Political Contributions

Covered Persons are prohibited from making political contributions for the purpose of obtaining or retaining any Legg Mason Registered Adviser or its affiliates as investment advisers. Covered Persons are specifically prohibited from making political contributions to any person for the purpose of influencing the selection or retention of an investment adviser by a government entity. Covered Persons will be required to certify annually that they have and will comply with this provision.

II. Personal Securities Transactions

A. Prohibited Transactions in Individual Securities

Covered Persons are subject to the following restrictions on their personal trading activities in individual securities:

Fraudulent Transactions. In connection with the purchase or sale, directly or indirectly, by a Covered Person of (A) a Reportable Security which, within the most recent fifteen (15) calendar days, (i) is or has been held by a Legg Mason client, or (ii) is being or has been considered by a Legg Mason Registered Adviser for purchase by a client, or (B) an Equivalent Security thereof, Covered Persons are prohibited from:

a.	Employing any device, scheme or artifice to defraud Legg Mason’s clients;

b.	Making any untrue statement of a material fact or omitting to state a material fact necessary to make the statements made, in light of the circumstances under which they were made, not misleading;

c.	Engaging in any act, practice or course of business that operates or would operate as a fraud or deceit on Legg Mason’s clients; or

d.	Engaging in any manipulative practice with respect to Legg Mason’s clients.

2.	Inside Information. Covered Persons are prohibited from engaging in any transaction in a Security (or Equivalent Security) at a time when the Covered Person is in possession of material non-public information regarding the Security or the issuer of the Security.

3.	Market Manipulation. Covered Persons are prohibited from engaging in any transactions in a Security (or Equivalent Security) intended to raise, lower or maintain the price of that Security or to create a false appearance of active trading in that Security.

Trading on the Knowledge of Client Transactions. Covered Persons are prohibited from engaging in any transactions in a Security (or an Equivalent Security) on the basis of any information they may be in possession of to the effect that (i) a Legg Mason Registered Adviser is or may be considering an investment in or sale of such Security on behalf of its clients or (ii) has or may have an open order in such Security on behalf of its clients.

Legg Mason, Inc. Stock. Covered Persons are prohibited from engaging in any transaction in Legg Mason securities that is not in compliance with the “Legg Mason, Inc. Policies and Procedures Regarding Acquisitions and Dispositions of Legg Mason Securities,” as the same may be amended from time to time. A copy of this policy is available on the Legg Mason Legal and Compliance Website.

B. Prohibited Transactions in Reportable Funds

Market Timing in Reportable Funds. No Covered Person may use his or her knowledge of the portfolio holdings or investment activities of a Reportable Fund to engage in any short-term or other abusive trading strategy involving such Fund that may conflict with the best interests of the Fund and its shareholders.

60-Day Holding Period for Investments in Proprietary Funds. Subject to the exemptions set forth below, no Covered Person may sell (or exchange out of) shares of a Proprietary Fund in which the Covered Person has a Beneficial Interest if the Covered Person has not held the shares of the same Proprietary Fund for sixty (60) calendar days, including any individual retirement account or 401(k) participant account.

Additionally, Proprietary Funds that are sold in the LM 401(k) account are also subject to a 60-day minimum waiting period. No Covered Person may buy (or exchange into) shares of a Proprietary Fund within sixty (60) calendar days of a sell of (or exchange out of) shares of the same Proprietary Fund within the same LM 401(k) account.

The following Securities Transactions involving Proprietary Funds are exempt from the 60-day minimum holding period requirement set forth in this Section II.B.2 and II.B.3:

a.	Money Market Funds and Other Short-Term Trading Vehicles. Purchases or redemptions of Proprietary Funds that are money market funds or that hold themselves out as short-term trading vehicles.

Managed Accounts.
