As a result of the successful completion of the issuer tender offer for up to 100% of the outstanding shares of common stock (the “Tender Offer”) which expired on October 1, 2024, the proposals to convert the Fund to a perpetual fund by eliminating the Fund’s term, which was scheduled to end at the close of business on December 2, 2024, and eliminating the Fund’s fundamental policy to liquidate on or about December 2, 2024 approved by stockholders on June 10, 2024 and in the offer to purchase relating to the Tender Offer will be implemented. In particular:
Since the Fund maintained at least $50 million of net assets following the Tender Offer, the Fund has changed its name from “Western Asset Investment Grade Defined Opportunity Trust Inc.” to “Western Asset Investment Grade Opportunity Trust Inc.” on November 1, 2024.

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. There can be no assurance the Fund will achieve its investment objectives.
The Fund seeks to achieve its investment objectives by investing, under normal market conditions, at least 80% of its net assets in investment grade corporate fixed income securities of varying maturities. The Fund may invest up to 20% of its net assets in corporate fixed income securities of below investment grade quality (commonly known as “high yield” or “junk” bonds) at the time of investment and other securities, including obligations of the U.S. government, its agencies or instrumentalities, common stocks, warrants and depositary receipts. While the Fund may invest up to 20% of its net assets in below investment grade securities, the Fund will, under normal market conditions, maintain a portfolio with an overall dollar-weighted average of investment grade credit quality. The Fund may invest up to 20% of its net assets in securities of foreign issuers located anywhere in the world, including issuers located in emerging market countries. Additionally, the Fund may invest up to 20% of its net assets in non-U.S. dollar denominated securities.
The Fund may invest in derivative instruments, such as options contracts, futures contracts, options on futures contracts, indexed securities, credit default swaps and other swap agreements, provided that the Fund’s exposure to derivative instruments, as measured by the total notional amount of all such instruments, will not exceed 20% of its net assets.
In purchasing securities and other investments for the Fund, we may take full advantage of the entire range of maturities and durations offered by corporate fixed income securities and may adjust the average maturity or duration of the Fund’s portfolio from time to time, depending on our assessment of the relative yields available on securities of different maturities and durations and our expectations of future changes in interest rates.
The Fund may take on leveraging risk by utilizing certain management techniques, whereby it will segregate liquid assets, enter into offsetting transactions or own positions covering its obligations. To the extent the Fund covers its commitment under such a portfolio management technique, such instrument will not be considered a senior security for the purposes of the Investment Company Act of 1940. However, as a fundamental policy, the Fund will not leverage its capital structure by issuing senior securities such as preferred shares or debt instruments.
At Western Asset Management Company, LLC (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

Fund overview (cont’d)
management, oversight and coordination of the Fund are Michael Buchanan, Daniel Alexander, Ryan Brist, Kurt Halvorson, Blanton Keh and Molly Schwartz.
Q. What were the overall market conditions during the Fund’s reporting period?
A. The overall U.S. fixed income market experienced periods of volatility but generated a positive return over the twelve-months ended November 30, 2024. The market was driven by several factors, including resilient economic growth, moderating inflation, shifting U.S. Federal Reserve (Fed) monetary policy, and several geopolitical issues.
Short-term U.S. Treasury yields declined as the Fed lowered interest rates in September
2024 (the first reduction since 2020) and again in November 2024. The two-year Treasury yield began the reporting period at 4.73% and ended the period at 4.13%. Its high for the period was 5.04% on April 30, 2024, and its low of 3.49% occurred on September 24, 2024.
Long-term U.S. Treasury yields also declined given easing inflation and loosening Fed monetary policy. The ten-year Treasury yield began the reporting period at 4.37% and ended at 4.18%. Its high for the period was 4.70% on April 25, 2024, and its low of 3.63% occurred on September 16, 2024.
All told, the Bloomberg U.S. Aggregate Indexi returned 6.88% for the twelve months ended November 30, 2024. Comparatively, the Bloomberg U.S. Credit Indexii returned 8.36% over the same period and the Bloomberg U.S. Corporate High Yield — 2% Issuer Cap Indexiii returned 12.71%.
Q. How did we respond to these changing market conditions?
A. During the reporting period, the Fund shifted some exposure from securities rated BBB to securities rated A, while still favoring the lower end of the quality spectrum overall. Regarding duration positioning, the Fund trimmed but maintained a modest duration overweight and yield curve steepener bias. On a sector basis, the Fund reduced its exposure in the consumer non-cyclicals1 and added to insurance. Within the consumer cyclical2 sector, the Fund added to its high-yield holdings. In addition, the Fund closed both its long investment-grade and high-yield index swap (CDX) positions by the end of the reporting period.
Performance review
For the twelve months ended November 30, 2024, Western Asset Investment Grade Opportunity Trust Inc. returned 8.01% based on its net asset value (NAV)iv and 7.57% based on its New York Stock Exchange (NYSE) market price per share. The Fund’s unmanaged benchmark, the Bloomberg U.S. Credit Index, returned 8.36% for the same period.
The Fund has a practice of seeking to maintain a relatively stable level of distributions to shareholders. This practice has no impact on the Fund’s investment strategy and may reduce

During the twelve-month period, the Fund made distributions to shareholders totaling $0.84 per share of which $0.01 will be treated as a return of capital for tax purposes.* The performance table shows the Fund’s twelve-month total return based on its NAV and market price as of November 30, 2024.

‡ Total return assumes the reinvestment of all distributions, including returns of capital, in additional shares in accordance with the Fund’s Dividend Reinvestment Plan.
Q. What were the leading contributors to performance?
A. Among the largest contributors to the Fund’s relative performance during the reporting period was its positioning in a number of sectors/industries, including overweights to banking and insurance and underweight to sovereigns. In terms of issue selection, holdings within the brokerage (overweight Charles Schwab), communications (overweight Charter), and consumer cyclical (overweight Las Vegas Sands) sectors added the most value. The Fund’s quality biases were also rewarded, led by an overweight to lower quality securities, as they outperformed their higher quality counterparts. Duration positioning also contributed to performance as yields decreased over the reporting period.
Q. What were the leading detractors from performance?
A. An underweight to real estate investment trusts (REITs) detracted from performance as the sector outperformed during the reporting period. Issue selection within the consumer non-cyclicals sector (underweight Bristol Myers) and banking (underweight Morgan Stanley and Sumitomo Mitsui) sectors also detracted.

RISKS:The Fund is a non-diversified, 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 objectives. 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 holdings. The Fund may invest in lower rated higher yielding bonds or “junk bonds”, which are subject to greater liquidity and credit risk (risk of default) than higher rated obligations. The Fund may use derivatives, such as options and futures, which can be illiquid, may disproportionately increase losses and have a potentially large impact on Fund performance. The Fund may invest in securities or engage in transactions that have the economic effects of leverage which can increase the risk and volatility of the Fund. The market values of securities or other assets will fluctuate, sometimes sharply and unpredictably, due to changes in general market conditions, overall economic trends or events, governmental actions or intervention, actions taken by the U.S. Federal Reserve or foreign central banks, market disruptions caused by trade disputes or other factors, political developments, armed conflicts, economic sanctions and countermeasures in response to sanctions, major cybersecurity events, investor sentiment, the global and domestic effects of a pandemic, and other factors that may or may not be related to the issuer of the security or other asset. The Fund may also invest in money market funds, including funds affiliated with the Fund’s manager and subadvisers. For

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.

Notes to financial statements
1. Organization and significant accounting policies
Western Asset Investment Grade Opportunity Trust Inc. (formerly Western Asset Investment Grade Defined Opportunity Trust Inc.) (the “Fund”) was incorporated in Maryland on April 24, 2009 and is registered as a non-diversified, closed-end management investment company under the Investment Company Act of 1940, as amended (the “1940 Act”). The Fund’s primary investment objective is to provide current income. As a secondary investment objective, the Fund will seek capital appreciation. There can be no assurance the Fund will achieve its investment objectives. The Fund seeks to achieve its investment objectives by investing, under normal market conditions, at least 80% of its net assets in investment grade corporate fixed income securities of varying maturities.
At the Fund’s Special Meeting held on June 7, 2024, stockholders approved the proposal to convert the Fund to a perpetual fund by eliminating the Fund’s term, which was scheduled to end at the close of business on December 2, 2024, and eliminating the Fund’s fundamental policy to liquidate on or about December 2, 2024. Since the Fund maintained at least $50 million of net assets following a tender offer (See Note 5, “Tender Offer”), the Fund changed its name from Western Asset Investment Grade Defined Opportunity Trust Inc. to Western Asset Investment Grade Opportunity Trust Inc. and the conversion became effective on November 1, 2024.
The Fund follows the accounting and reporting guidance in Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946, Financial Services – Investment Companies (ASC 946). The following are significant accounting policies consistently followed by the Fund and are in conformity with U.S. generally accepted accounting principles (“GAAP”), including, but not limited to, ASC 946. 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 typically 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

32
Western Asset Investment Grade Opportunity Trust Inc. 2024 Annual Report

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.
Pursuant to policies adopted by the Board of Directors, the Fund’s manager has been designated as the valuation designee and is responsible for the oversight of the daily valuation process. The Fund’s manager is assisted by the Global Fund Valuation Committee (the Valuation Committee). The Valuation Committee is responsible for making fair value determinations, evaluating the effectiveness of the Fund’s pricing policies, and reporting to the Fund’s manager and 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.

Notes to financial statements(cont’d)
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 — unadjusted quoted prices in active markets for identical investments
Level 2 — other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.)
Level 3 — significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments)
The inputs or methodologies used to value securities are not necessarily an indication of the risk associated with investing in those securities.
The following is a summary of the inputs used in valuing the Fund’s assets and liabilities carried at fair value:

Reflects the unrealized appreciation (depreciation) of the instruments.
(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 securities 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 appreciation or depreciation in the Statement of Operations and the Fund recognizes a realized gain or loss when the contract is closed.
Futures contracts involve, to varying degrees, risk of loss in excess of the amounts reflected in the financial statements. In addition, there is the risk that the Fund may not be able to enter into a closing transaction because of an illiquid secondary market.
(c) 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.
Non-deliverable forward foreign currency exchange contracts are settled with the counterparty in cash without the delivery of foreign currency.
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
Western Asset Investment Grade Opportunity Trust Inc. 2024 Annual Report

35

Notes to financial statements(cont’d)
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. 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 net 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 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 November 30, 2024, the Fund did not hold any credit default swaps to sell protection.
For average notional amounts of swaps held during the year ended November 30, 2024, 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

36
Western Asset Investment Grade Opportunity Trust Inc. 2024 Annual Report

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 CDS 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 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 CDS 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 CDS 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. CDS 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.
(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
Western Asset Investment Grade Opportunity Trust Inc. 2024 Annual Report

37

Notes to financial statements(cont’d)
offset 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 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 offset between the lender and the borrower.
(f) Securities traded on a when-issued and delayed delivery basis.The Fund may trade securities on a when-issued or delayed delivery basis. In when-issued and delayed delivery transactions, the securities are purchased or sold by the Fund with payment and delivery taking place in the future in order to secure what is considered to be an advantageous price and yield to the Fund at the time of entering into the transaction.
Purchasing such securities involves risk of loss if the value of the securities declines prior to settlement. These securities are subject to market fluctuations and their current value is determined in the same manner as for other securities.
(g) 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.
(h) Credit and market risk.The Fund invests in high-yield instruments that are subject to certain credit and market risks. The yields of high-yield obligations reflect, among other things, perceived credit and market risks. The Fund’s investments in securities rated below investment grade typically involve risks not associated with higher rated securities

38
Western Asset Investment Grade Opportunity Trust Inc. 2024 Annual Report

including, among others, greater risk related to timely and ultimate payment of interest and principal, greater market price volatility and less liquid secondary market trading.
(i) 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 may 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.
(j) 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 (OTC) 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 net asset value per share 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 Master Agreements do not result in an offset of reported amounts of financial assets and
Western Asset Investment Grade Opportunity Trust Inc. 2024 Annual Report

39

Notes to financial statements(cont’d)
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 OTC 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 November 30, 2024, the Fund held forward foreign currency contracts with credit related contingent features which had a liability position of $73,845. 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.
(k) 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) is recorded on the accrual basis. Amortization of premiums and accretion of discounts on debt securities are recorded to interest income over the lives of the respective securities, except for premiums on certain callable debt securities, which are amortized to the earliest call date. Paydown gains and losses on mortgage- and asset-backed securities are recorded as adjustments to interest income. Dividend income is recorded on the ex-dividend date. Foreign dividend income is recorded on the ex-dividend date or as soon as practicable after the Fund determines the existence of a dividend declaration after exercising reasonable due diligence. 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.
(l) 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. 
(m) 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.
(n) Federal and other taxes.It is the Fund’s policy to comply with the federal income and excise tax requirements of the Internal Revenue Code of 1986 (the “Code”), as amended, applicable to regulated investment companies. Accordingly, the Fund intends to distribute its taxable income and net realized gains, if any, to shareholders in accordance with timing requirements imposed by the Code. Therefore, no federal or state income tax provision is required in the Fund’s financial statements.
Management has analyzed the Fund’s tax positions taken on income tax returns for all open tax years and has concluded that as of November 30, 2024, no provision for income tax is required in the Fund’s financial statements. The Fund’s federal and state income and federal

40
Western Asset Investment Grade Opportunity Trust Inc. 2024 Annual Report

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.
(o) Reclassification.GAAP requires that certain components of net assets be reclassifiedto 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 Fund had no reclassifications.

Western Asset Singapore, Western Asset Japan and Western Asset London provide certain subadvisory services to the Fund relating to currency transactions and investments in non-U.S. dollar denominated debt securities. For its services, FTFA pays Western Asset a fee monthly, at an annual rate equal to 70% of the net management fee it receives from the Fund. In turn, Western Asset pays Western Asset Singapore, Western Asset Japan and Western Asset London 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 each such non-U.S. subadviser to manage.
The manager has agreed to waive the Fund’s management fee to an extent sufficient to offset the net management fee payable in connection with any investment in an affiliated money market fund (the affiliated money market fund waiver).
Effective June 1, 2022, FTFA implemented a voluntary investment management fee waiver of 0.05% that continued until May 31, 2024.
Effective June 10, 2024, FTFA implemented a voluntary investment management fee waiver of 0.10% that will continue until June 7, 2026.
During the year ended November 30, 2024, fees waived and/or expenses reimbursed amounted to $126,402, which included an affiliated money market fund waiver of $1,632.
All officers and one Director of the Fund are employees of Franklin Resources or its affiliates and do not receive compensation from the Fund.

Notes to financial statements(cont’d)
*
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 tax deferral of losses on straddles, the realization
for tax purposes of unrealized gains (losses) on certain futures and foreign currency contracts, the difference
between cash and accrual basis distributions paid 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 the tax
deferral of losses on wash sales and the difference between book and tax amortization methods for premium on
fixed income securities.

To the Board of Directors and Shareholders of Western Asset Investment Grade Opportunity Trust Inc.
Opinion on the Financial Statements
We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Western Asset Investment Grade Opportunity Trust Inc. (the Fund) as of November 30, 2024, the related statement of operations for the year ended November 30, 2024, the statement of changes in net assets for each of the two years in the period ended November 30, 2024, including the related notes, and the financial highlights for each of the five years in the period ended November 30, 2024 (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund as of November 30, 2024, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period ended November 30, 2024 and the financial highlights for each of the five years in the period ended November 30, 2024 in conformity with accounting principles generally accepted in the United States of America.
Basis for Opinion
These financial statements are the responsibility of the Fund’s management. Our responsibility is to express an opinion on the Fund’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits of these financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.
Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included confirmation of securities owned as of November 30, 2024 by correspondence with the custodian, agent banks and brokers; when replies were not received, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

Investment Objectives
The Fund’s primary investment objective is to provide current income. As a secondary investment objective, the Fund will seek capital appreciation. The Fund’s investment objectives are fundamental and may not be changed without stockholder approval.
Principal Investment Policies and Strategies
The Fund seeks to achieve its investment objectives by investing, under normal market conditions, at least 80% of its net assets in a portfolio of investment grade corporate fixed income securities of varying maturities. “Corporate fixed income securities” include corporate bonds, debentures, notes and other similar types of corporate debt instruments, as well as preferred shares, senior secured floating rate and fixed rate loans or debt (“Senior Loans”), second lien or other subordinated or unsecured floating rate and fixed rate loans or debt (“Second Lien Loans”), loan participations, payment-in-kind securities, zero-coupon bonds, bank certificates of deposit, fixed time deposits and bankers’ acceptances. Certain corporate debt instruments, such as convertible securities, may also include the right to participate in equity appreciation, and Western Asset will generally evaluate those instruments based primarily on their debt characteristics. The Fund’s policy to invest, under normal market conditions, at least 80% of its net assets in a portfolio of investment grade corporate fixed income securities of varying maturities may be changed by the Board without a stockholder vote, except that the Fund will give stockholders at least 60 days’ notice of any change to such policy.
Under normal market conditions, the Fund will invest at least 50% of its net assets in corporate bonds, debentures and notes.
The Fund may invest up to 20% of its net assets in (i) corporate fixed income securities of below investment grade quality (commonly referred to as “high-yield” securities or “junk bonds”) at the time of investment and (ii) other securities, including obligations of the U.S. Government, its agencies or instrumentalities, common stocks, warrants and depositary receipts. Corporate fixed income securities of below investment grade quality are regarded as having predominately speculative characteristics with respect to the issuer’s capacity to pay interest and repay principal.
While the Common Stock issued by the Fund will not be rated by an NRSRO, it is expected that, under normal market conditions, the Fund will maintain on an ongoing basis a dollar-weighted average credit quality of portfolio holdings of at least BBB- or higher by Standard & Poor’s Ratings Services (“S&P”) or Fitch Ratings, Inc. (“Fitch”) or Baa3 or higher by Moody’s Investors Service, Inc. (“Moody’s”), or comparable quality as determined by Western Asset. For securities with legal final maturities of 270 days or less, Western Asset may use the underlying credit’s short-term ratings as a proxy for establishing the minimum credit requirement.
Western Asset Investment Grade Opportunity Trust Inc.

57

Summary of information regarding the Fund (unaudited) (cont’d)
“Investment grade” quality securities are those that, at the time of investment, are either rated by one of the NRSROs that rate such securities within the four highest letter grades (including BBB- or higher by S&P or Fitch or Baa3 or higher by Moody’s), or if unrated are determined by Western Asset to be of comparable quality. In the event that a security is rated by multiple NRSROs and receives different ratings, the Fund will treat the security as being rated in the highest rating category received from an NRSRO (such securities are commonly referred to as split-rated securities). Securities rated BBB by S&P and Fitch are the lowest category of investment grade securities and are regarded as having an adequate capacity to pay interest and repay principal, although adverse economic conditions or changing circumstances are more likely to impair the issuer’s capacity to pay interest and repay principal for debt in this category than in higher rated categories. Securities rated Baa by Moody’s are regarded as having an adequate capacity to pay interest and repay principal for the present, but certain protective elements may be lacking or may be characteristically unreliable over any great length of time. Such securities lack outstanding investment characteristics and, in fact, have speculative characteristics as well. Ratings assigned by a rating agency are not absolute standards of credit quality and do not evaluate market risks or the liquidity of the securities.
Although the Fund invests primarily in securities of U.S. issuers, the Fund may invest up to 20% of its net assets in securities of foreign issuers located anywhere in the world, including issuers located in emerging market countries. A foreign issuer is a company organized under the laws of a foreign country that is principally traded in the financial markets of a foreign country. Additionally, the Fund may invest up to 20% of its net assets in non-U.S. dollar denominated securities.
The Fund may invest in derivative instruments, such as options contracts, futures contracts, options on futures contracts, indexed securities, credit default swaps and other swap agreements; provided that the Fund’s exposure to derivative instruments, as measured by the total notional amount of all such instruments, will not exceed 20% of its net assets. With respect to this limitation, the Fund may net derivatives with opposite exposure to the same underlying instrument. The Fund will not include derivative instruments for the purposes of the Fund’s policy to invest at least 80% of its net assets in investment grade corporate fixed income securities.
The Fund may invest up to 20% of its net assets in illiquid securities, which are securities that cannot be sold within seven days in the ordinary course of business at approximately the value at which the Fund has valued the securities.
In order to reduce the interest rate risk inherent in the Fund’s underlying investments, the Fund may enter into interest rate swap or cap transactions for hedging or investment purposes.

58
Western Asset Investment Grade Opportunity Trust Inc.

It is expected that, under normal market conditions, the Fund will maintain on an ongoing basis a dollar-weighted average credit quality of portfolio holdings of at least BBB- or higher by S&P or Fitch or Baa3 or higher by Moody’s, or comparable quality. For securities with legal final maturities of 270 days or less, Western Asset may use the underlying credit’s short-term ratings as a proxy for establishing the minimum credit requirement. The Fund may purchase unrated securities if Western Asset determines that the securities are of comparable quality to rated securities that the Fund may purchase.
In purchasing securities and other investments for the Fund, Western Asset may take full advantage of the entire range of maturities and durations offered by corporate fixed-income securities and may adjust the average maturity or duration of the Fund’s portfolio from time to time, depending on its assessment of the relative yields available on securities of different maturities and durations and its expectations of future changes in interest rates. As the termination date of the Fund approaches, Western Asset may manage the Fund’s assets in a manner that causes the dollar-weighted average maturity of its assets to shorten and/or increase the percentage of cash or cash equivalents in the Fund’s portfolio.
The Fund may lend its portfolio securities so long as the terms and the structure of such loans are not inconsistent with the requirements of the 1940 Act.
As a fundamental policy, the Fund will not leverage its capital structure by issuing senior securities such as preferred shares or debt instruments. However, the Fund may borrow for temporary or emergency purposes as permitted by the 1940 Act.
Principal Risk Factors
The Fund is a non-diversified, 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 objectives. Your Common Stock at any point in time may be worth less than you invested, even after taking into account the reinvestment of Fund dividends and distributions.
Investment and Market Risk. An investment in the Fund is subject to investment risk, including the possible loss of the entire amount that you invest. Your investment in the Common Stock represents an indirect investment in the fixed income securities and other investments owned by the Fund, most of which could be purchased directly. The value of the Fund’s portfolio securities may move up or down, sometimes rapidly and unpredictably. At any point in time, your Common Stock may be worth less than your original investment, even after taking into account the reinvestment of Fund dividends and distributions.
Fixed Income Securities Risk. In addition to the risks described elsewhere in this section with respect to valuations and liquidity, fixed income securities, including high-yield securities, are also subject to certain risks, including:
Western Asset Investment Grade Opportunity Trust Inc.

59

Summary of information regarding the Fund (unaudited) (cont’d)
Issuer Risk. The value of fixed income securities may decline for a number of reasons that directly relate to the issuer, such as management performance, financial leverage and reduced demand for the issuer’s goods and services.
Interest Rate Risk. The market price of the Fund’s investments will change in response to changes in interest rates and other factors. During periods of declining interest rates, the market price of fixed income securities generally rises. Conversely, during periods of rising interest rates, the market price of such securities generally declines. The magnitude of these fluctuations in the market price of fixed income securities is generally greater for securities with longer maturities. Additionally, such risk may be greater during the current period of historically low interest rates. Fluctuations in the market price of the Fund’s securities will not affect interest income derived from securities already owned by the Fund, but will be reflected in the Fund’s net asset value. The Fund may utilize certain strategies, including investments in structured notes or interest rate swap or cap transactions, for the purpose of reducing the interest rate sensitivity of the portfolio and decreasing the Fund’s exposure to interest rate risk, although there is no assurance that it will do so or that such strategies will be successful.
Prepayment Risk. During periods of declining interest rates, the issuer of a security may exercise its option to prepay principal earlier than scheduled, forcing the Fund to reinvest the proceeds from such prepayment in lower yielding securities, which may result in a decline in the Fund’s income and distributions to stockholders. This is known as prepayment or “call” risk. Debt securities frequently have call features that allow the issuer to redeem the security at dates prior to its stated maturity at a specified price (typically greater than par) only if certain prescribed conditions are met. An issuer may choose to redeem a debt security if, for example, the issuer can refinance the debt at a lower cost due to declining interest rates or an improvement in the credit standing of the issuer.
Reinvestment Risk. Reinvestment risk is the risk that income from the Fund’s portfolio will decline if and when the Fund invests the proceeds from matured, traded or called fixed income securities at market interest rates that are below the portfolio’s current earnings rate. A decline in income could affect the Fund’s Common Stock price, its distributions or its overall return.
Credit Risk. If an issuer or guarantor of a security held by the Fund or a counterparty to a financial contract with the Fund defaults or its credit is downgraded, or is perceived to be less creditworthy, or if the value of the assets underlying a security declines, the value of your investment will typically decline. Changes in actual or perceived creditworthiness may occur quickly. The Fund could be delayed or hindered in its enforcement of rights against an issuer, guarantor or counterparty. Subordinated securities are more likely to suffer a credit

60
Western Asset Investment Grade Opportunity Trust Inc.

loss than non-subordinated securities of the same issuer and will be disproportionately affected by a default, downgrade or perceived decline in creditworthiness. 
Below Investment Grade (High-Yield or Junk Bond) Securities Risk. The Fund may invest up to 20% of its net assets in corporate fixed income securities of below investment grade quality (commonly referred to as “high-yield” securities or “junk bonds”) at the time of investment. High yield debt securities are generally subject to greater credit risks than higher-grade debt securities, including the risk of default on the payment of interest or principal. High yield debt securities are considered speculative, typically have lower liquidity and are more difficult to value than higher grade bonds. High yield debt securities tend to be volatile and more susceptible to adverse events, credit downgrades and negative sentiments and may be difficult to sell at a desired price, or at all, during periods of uncertainty or market turmoil.
Senior Loan Risk. Senior Loans are usually rated below investment grade. As a result, the risks associated with Senior Loans are similar to the risks of below investment grade securities. While Senior Loans are typically senior and secured in contrast to other below investment grade securities which are often subordinated and unsecured, nevertheless, if a borrower of a Senior Loan defaults or goes into bankruptcy, the Fund may recover only a fraction of what is owed on the Senior Loan or nothing at all. Senior Loans are subject to a number of risks described elsewhere in this Prospectus, including credit risk, liquidity risk and management risk.
There is less readily available and reliable information about most Senior Loans than is the case for many other types of securities. If there is no independent evaluation of a Senior Loan by an NRSRO, Western Asset will rely on its own evaluation of credit quality to determine the Senior Loan’s equivalent credit rating. As a result, the Fund is particularly dependent on the analytical abilities of Western Asset when investing in Senior Loans.
Although Senior Loans in which the Fund will invest generally will be secured by specific collateral, there can be no assurance that liquidation of such collateral would satisfy the borrower’s obligation in the event of non-payment of scheduled interest or principal or that such collateral could be readily liquidated. Moreover, any specific collateral used to secure a Senior Loan may decline in value or become illiquid, which would adversely affect the Senior Loan’s value. In the event of the bankruptcy of a borrower, the Fund could experience delays or limitations with respect to its ability to realize the benefits of the collateral securing a Senior Loan. If the terms of a Senior Loan do not require the borrower to pledge additional collateral in the event of a decline in the value of the already pledged collateral, the Fund will be exposed to the risk that the value of the collateral will not at all times equal or exceed the amount of the borrower’s obligations under the Senior Loans. To the extent that a Senior Loan is collateralized by stock in the borrower or its subsidiaries, such stock may lose all of its value in the event of the bankruptcy of the borrower.
Western Asset Investment Grade Opportunity Trust Inc.

Summary of information regarding the Fund (unaudited) (cont’d)
Uncollateralized or under-collateralized Senior Loans involve a greater risk of loss. Some Senior Loans are subject to the risk that a court, pursuant to fraudulent conveyance or other similar laws, could subordinate the Senior Loans to presently existing or future indebtedness of the borrower or take other action detrimental to lenders, including the Fund. Such court action could under certain circumstances include invalidation of Senior Loans.
If legislation or state or federal regulations impose additional requirements or restrictions on the ability of financial institutions to make loans, the availability of Senior Loans for investment by the Fund may be adversely affected. In addition, such requirements or restrictions could reduce or eliminate sources of financing for certain Borrowers. This would increase the risk of default. If legislation or federal or state regulations require financial institutions to dispose of Senior Loans that are considered highly levered transactions or subject Senior Loans to increased regulatory scrutiny, financial institutions may determine to sell such Senior Loans. Such sales could result in prices that, in the opinion of Western Asset, do not represent fair value. If the Fund attempts to sell a Senior Loan at a time when a financial institution is engaging in such a sale, the price the Fund could get for the Senior Loan may be adversely affected.
The Fund may acquire Senior Loan assignments or participations. The purchaser of an assignment typically succeeds to all the rights and obligations of the assigning institution and becomes a lender under the credit agreement with respect to the debt obligation; however, the purchaser’s rights can be more restricted than those of the assigning institution, and, in any event, the Fund may not be able to unilaterally enforce all rights and remedies under the loan and with regard to any associated collateral. A participation typically results in a contractual relationship only with the institution selling the participation, not with the borrower. In purchasing participations, the Fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement against the borrower, and the Fund may not directly benefit from the collateral supporting the debt obligation in which it has purchased the participation. As a result, the Fund will be exposed to the credit risk of both the borrower and the institution selling the participation.
Second Lien Loans Risk. Second Lien Loans generally are subject to similar risks as those associated with investments in Senior Loans. Because Second Lien Loans are subordinated or unsecured and thus lower in priority of payment to Senior Loans, they are subject to the additional risk that the cash flow of the borrower and property securing the loan or debt, if any, may be insufficient to meet scheduled payments after giving effect to the senior secured obligations of the borrower. This risk is generally higher for subordinated unsecured loans or debt, which are not backed by a security interest in any specific collateral. Second Lien Loans generally have greater price volatility than Senior Loans and may be less liquid. There is also a possibility that originators will not be able to sell participations in Second

62
Western Asset Investment Grade Opportunity Trust Inc.

Lien Loans, which would create greater credit risk exposure for the holders of such loans. Second Lien Loans share the same risks as other below investment grade securities.
Liquidity Risk. The Fund may invest up to 20% of its net assets in illiquid securities. Liquidity risk exists when particular investments are difficult to sell. Securities may become illiquid after purchase by the Fund, particularly during periods of market turmoil. When the Fund holds illiquid investments, the portfolio may be harder to value, especially in changing markets, and if the Fund is forced to sell these investments in order to segregate assets or for other cash needs, the Fund may suffer a loss.
Derivatives Risk. The Fund may utilize a variety of derivative instruments for investment, hedging or risk management purposes, such as options contracts, futures contracts, options on futures contracts, indexed securities, credit default swaps and other swap agreements; provided that the Fund’s exposure to derivative instruments, as measured by the total notional amount of all such instruments, will not exceed 20% of its net assets. With respect to this limitation, the Fund may net derivatives with opposite exposure to the same underlying instrument. The Fund will not include derivative instruments for the purposes of the Fund’s policy to invest at least 80% of its net assets in investment grade corporate fixed income securities. Using derivatives can increase Fund losses and reduce opportunities for gains when market prices, interest rates, currencies, or the derivatives themselves behave in a way not anticipated by the Fund. Using derivatives also can have a leveraging effect and increase Fund volatility. Certain derivatives have the potential for unlimited loss, regardless of the size of the initial investment. Derivatives may not be available at the time or price desired, may be difficult to sell, unwind or value, and the counterparty may default on its obligations to the Fund. Derivatives are generally subject to the risks applicable to the assets, rates, indices or other indicators underlying the derivative. The value of a derivative may fluctuate more than the underlying assets, rates, indices or other indicators to which it relates. Use of derivatives may have different tax consequences for the Fund than an investment in the underlying security, and those differences may affect the amount, timing and character of income distributed to shareholders. The U.S. government and foreign governments are in the process of adopting and implementing regulations governing derivatives markets, including mandatory clearing of certain derivatives, margin and reporting requirements. The ultimate impact of the regulations remains unclear. Additional regulation of derivatives may make derivatives more costly, limit their availability or utility, otherwise adversely affect their performance or disrupt markets.
Effective August 19, 2022, the Fund began operating under Rule 18f-4 under the 1940 Act which, among other things, governs the use of derivative investments and certain financing transactions (e.g. reverse repurchase agreements) by registered investment companies. Among other things, Rule 18f-4 requires funds that invest in derivative instruments beyond a specified limited amount to apply a value at risk (VaR) based limit to their use of certain
Western Asset Investment Grade Opportunity Trust Inc.

63

Summary of information regarding the Fund (unaudited) (cont’d)
derivative instruments and financing transactions and to adopt and implement a derivatives risk management program. A fund that uses derivative instruments in a limited amount is not subject to the full requirements of Rule 18f-4. Compliance with Rule 18f-4 by the Fund could, among other things, make derivatives more costly, limit their availability or utility, or otherwise adversely affect their performance. Rule 18f-4 may limit the Fund’s ability to use derivatives as part of its investment strategy.
Credit default swap contracts involve heightened risks and may result in losses to the Fund. Credit default swaps may be illiquid and difficult to value. When the Fund sells credit protection via a credit default swap, credit risk increases since the Fund has exposure to both the issuer whose credit is the subject of the swap and the counterparty to the swap.
Equity Risk. The values of equity securities, such as common stocks and preferred stocks, may decline due to general market conditions which are not specifically related to a particular company, such as real or perceived adverse economic conditions, changes in the general outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. They may also decline due to factors which affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry. Equity securities generally have greater price volatility than fixed income securities.
Convertible Securities Risk. A convertible security is a bond, debenture, note, preferred stock or other security that may be converted into or exchanged for a prescribed amount of common stock or other equity security of the same or a different issuer within a particular period of time at a specified price or formula. Before conversion, convertible securities have characteristics similar to nonconvertible income securities in that they ordinarily provide a stable stream of income with generally higher yields than those of common stocks of the same or similar issuers, but lower yields than comparable nonconvertible securities. The value of a convertible security is influenced by changes in interest rates, with investment value declining as interest rates increase and increasing as interest rates decline. The credit standing of the issuer and other factors also may have an effect on the convertible security’s investment value. Convertible securities rank senior to common stock in a corporation’s capital structure but are usually subordinated to comparable nonconvertible securities. Convertible securities may be subject to redemption at the option of the issuer at a price established in the convertible security’s governing instrument.
Foreign (Non-U.S.) Investment Risk. A fund that invests in foreign (non-U.S.) securities may experience more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies. The securities markets of many foreign countries are relatively small, with a limited number of companies representing a small number of industries. Investments in foreign securities (including those denominated in U.S. dollars) are subject to economic and political developments in the countries and regions where the issuers

64
Western Asset Investment Grade Opportunity Trust Inc.

operate or are domiciled, or where the securities are traded, such as changes in economic or monetary policies. Values may also be affected by restrictions on receiving the investment proceeds from a foreign country. Less information may be publicly available about foreign companies than about U.S. companies. Foreign companies are generally not subject to the same accounting, auditing and financial reporting standards as are U.S. companies. In addition, the Fund’s investments in foreign securities may be subject to the risk of nationalization or expropriation of assets, imposition of currency exchange controls or restrictions on the repatriation of foreign currency, confiscatory taxation, political or financial instability and adverse diplomatic developments. In addition, there may be difficulty in obtaining or enforcing a court judgment abroad. Dividends or interest on, or proceeds from the sale of, foreign securities may be subject to non-U.S. withholding taxes, and special U.S. tax considerations may apply.
The risks of foreign investment are greater for investments in emerging markets. Emerging market countries include any country which, at the time of investment, is represented in the J.P. Morgan Emerging Markets Bond Index Global (EMBI Global) or categorized by the International Bank for Reconstruction and Development (World Bank), in its annual categorization, as middle- or low-income. Emerging market countries typically have economic and political systems that are less fully developed, and that can be expected to be less stable, than those of more advanced countries. Low trading volumes may result in a lack of liquidity and in price volatility. Emerging market countries may have policies that restrict investment by foreigners, that require governmental approval prior to investments by foreign persons, or that prevent foreign investors from withdrawing their money at will. An investment in emerging market securities should be considered speculative.
Currency Risk. The value of investments in securities denominated in foreign currencies increases or decreases as the rates of exchange between those currencies and the U.S. dollar change. Currency conversion costs and currency fluctuations could erase investment gains or add to investment losses. Currency exchange rates can be volatile, and are affected by factors such as general economic conditions, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls and speculation. The Fund may be unable or may choose not to hedge its foreign currency exposure.
Management Risk. The Fund is subject to management risk because it is an actively managed investment portfolio. Western Asset and each individual portfolio manager will apply investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these will produce the desired results.
Short Sales Risk. If the price of the security sold short increases between the time of the short sale and the time the Fund replaces the borrowed security, the Fund will realize a loss, which may be substantial. A fund that engages in a short sale or short position may lose more money than the actual cost of the short sale or short position and its potential losses
Western Asset Investment Grade Opportunity Trust Inc.

65

Summary of information regarding the Fund (unaudited) (cont’d)
may be unlimited if the fund does not own the security sold short or the reference instrument and it is unable to close out of the short sale or short position.
Credit Crisis Liquidity and Volatility Risk. The markets for credit instruments, including fixed income securities, have experienced periods of extreme illiquidity and volatility. General market uncertainty and consequent repricing risk have led to market imbalances of sellers and buyers, which in turn have also resulted in significant valuation uncertainties in a variety of debt securities, including certain fixed income securities. These conditions resulted, and in many cases continue to result in greater volatility, less liquidity, widening credit spreads and a lack of price transparency, with many debt securities remaining illiquid and of uncertain value. During times of reduced market liquidity, the Fund may not be able to sell securities readily at prices reflecting the values at which the securities are carried on the Fund’s books. Sales of large blocks of securities by market participants, such as the Fund, that are seeking liquidity can further reduce security prices in an illiquid market. These market conditions may make valuation of some of the Fund’s securities uncertain and/or result in sudden and significant valuation increases or decreases in its holdings. Illiquidity and volatility in the credit markets may directly and adversely affect the setting of dividend rates on the Common Stock.
Valuation Risk. The sales price the Fund could receive for any particular portfolio investment may differ from the Fund’s valuation of the investment, particularly for securities that trade in thin or volatile markets or that are valued using a fair value methodology. These differences may increase significantly and affect Fund investments more broadly during periods of market volatility. The Fund’s ability to value its investments may be impacted by technological issues and/or errors by pricing services or other third party service providers. The valuation of the Fund’s investments involves subjective judgment.
Government Intervention in Financial Markets. U.S. federal and state governments and foreign governments, their regulatory agencies or self regulatory organizations may take additional actions that affect the regulation of the securities in which the Fund invests, or the issuers of such securities, in ways that are unforeseeable. Issuers of corporate fixed income securities might seek protection under the bankruptcy laws. Legislation or regulation may also change the way in which the Fund itself is regulated. Such legislation or regulation could limit or preclude the Fund’s ability to achieve its investment objectives. Western Asset will monitor developments and seek to manage the Fund’s portfolio in a manner consistent with achieving the Fund’s investment objectives, but there can be no assurance that it will be successful in doing so.
Counterparty Risk. The Fund may enter into transactions with counterparties that become unable or unwilling to fulfill their contractual obligations. There can be no assurance that any such counterparty will not default on its obligations to the Fund. In the event of a counterparty default, the Fund may be hindered or delayed in exercising rights against a

66
Western Asset Investment Grade Opportunity Trust Inc.

counterparty and may experience significant losses. To the extent that the Fund enters into multiple transactions with a single or small set of counterparties, the Fund will be subject to increased counterparty risk.
Inflation/Deflation Risk. Inflation risk is the risk that the value of certain assets or income from the Fund’s investments will be worth less in the future as inflation decreases the value of money. As inflation increases, the real value of the Common Stock and distributions on the Common Stock can decline. In addition, during any periods of rising inflation, the dividend rates or borrowing costs associated with the Fund’s use of leverage would likely increase, which would tend to further reduce returns to stockholders. Deflation risk is the risk that prices throughout the economy decline over time—the opposite of inflation. Deflation may have an adverse affect on the creditworthiness of issuers and may make issuer defaults more likely, which may result in a decline in the value of the Fund’s portfolio.
Leverage Risk. As a fundamental policy, the Fund will not leverage its capital structure by issuing senior securities such as preferred shares or debt instruments. However, the Fund may borrow for temporary or emergency purposes as permitted by the 1940 Act. The Fund may take on leveraging risk by, among other things, purchasing securities on a when-issued or delayed delivery basis, entering into credit default swaps or futures contracts, engaging in short sales or writing options on portfolio securities. When the Fund engages in transactions that have a leveraging effect on the Fund’s portfolio, the value of the Fund will be more volatile and all other risks will tend to be compounded. This is because leverage generally magnifies the effect of any increase or decrease in the value of the Fund’s underlying asset or creates investment risk with respect to a larger pool of assets than the Fund would otherwise have. Engaging in such transactions may cause the Fund to liquidate positions when it may not be advantageous to do so to satisfy its obligations or meet segregation requirements.
Market Events Risk. The market values of securities or other assets will fluctuate, sometimes sharply and unpredictably, due to factors such as economic events, governmental actions or intervention, actions taken by the U.S. Federal Reserve or foreign central banks, market disruptions caused by trade disputes, labor strikes or other factors, political developments, armed conflicts, economic sanctions and countermeasures in response to sanctions, major cybersecurity events, the global and domestic effects of widespread or local health, weather or climate events, and other factors that may or may not be related to the issuer of the security or other asset. Economies and financial markets throughout the world are increasingly interconnected. Economic, financial or political events, trading and tariff arrangements, public health events, terrorism, wars, natural disasters and other circumstances in one country or region could have profound impacts on global economies or markets. As a result, whether or not the fund invests in securities of issuers located in or with significant exposure to the countries or markets directly affected,

Summary of information regarding the Fund (unaudited) (cont’d)
the value and liquidity of the fund’s investments may be negatively affected. Ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Hamas and other militant groups in the Middle East have caused and could continue to cause significant market disruptions and volatility. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain fund investments as well as fund performance and liquidity. Following Russia’s invasion of Ukraine in 2022, Russian stocks lost all, or nearly all, of their market value. Other securities or markets could be similarly affected by past or future geopolitical or other events or conditions. Furthermore, events involving limited liquidity, defaults, non-performance or other adverse developments that affect one industry, such as the financial services industry, or concerns or rumors about any events of these kinds, have in the past and may in the future lead to market-wide liquidity problems, may spread to other industries, and could negatively affect the value and liquidity of the fund’s investments.
The long-term impact of the COVID-19 pandemic and its subsequent variants on economies, markets, industries and individual issuers is not known. The U.S. government and the Federal Reserve, as well as certain foreign governments and central banks, took extraordinary actions to support local and global economies and the financial markets in response to the COVID-19 pandemic. This and other government intervention into the economy and financial markets have resulted in a large expansion of government deficits and debt, the long term consequences of which are not known.
Raising the ceiling on U.S. government debt has become increasingly politicized. Any failure to increase the total amount that the U.S. government is authorized to borrow could lead to a default on U.S. government obligations, with unpredictable consequences for economies and markets in the U.S. and elsewhere. Recently, inflation and interest rates have been volatile and may increase in the future. These circumstances could adversely affect the value and liquidity of the fund’s investments, impair the fund’s ability to satisfy redemption requests, and negatively impact the fund’s performance.
The United States and other countries are periodically involved in disputes over trade and other matters, which may result in tariffs, investment restrictions and adverse impacts on affected companies and securities. For example, the United States has imposed tariffs and other trade barriers on Chinese exports, has restricted sales of certain categories of goods to China, and has established barriers to investments in China. Trade disputes may adversely affect the economies of the United States and its trading partners, as well as companies directly or indirectly affected and financial markets generally. The United States government has prohibited U.S. persons from investing in Chinese companies designated as related to the Chinese military. These and possible future restrictions could limit the fund’s opportunities for investment and require the sale of securities at a loss or make them illiquid. Moreover, the Chinese government is involved in a longstanding dispute with

Western Asset Investment Grade Opportunity Trust Inc.

Taiwan that has included threats of invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt unification of Taiwan by force, or if other geopolitical conflicts develop or get worse, economies, markets and individual securities may be severely affected both regionally and globally, and the value of the fund’s assets may go down.
When-Issued and Delayed-Delivery Transactions Risk. The Fund may purchase corporate fixed income securities on a when-issued basis, and may purchase or sell those securities for delayed delivery. When-issued and delayed-delivery transactions occur when securities are purchased or sold by the Fund with payment and delivery taking place in the future to secure an advantageous yield or price. Securities purchased on a when-issued or delayed-delivery basis may expose the Fund to counterparty risk of default as well as the risk that securities may experience fluctuations in value prior to their actual delivery. The Fund will not accrue income with respect to a when-issued or delayed-delivery security prior to its stated delivery date. Purchasing securities on a when-issued or delayed-delivery basis can involve the additional risk that the price or yield available in the market when the delivery takes place may not be as favorable as that obtained in the transaction itself. Similar concerns arise for securities sold on a delayed-delivery basis.
Market Price Discount from Net Asset Value. Shares of closed-end investment companies frequently trade at a discount from their net asset value. This risk is separate and distinct from the risk that the Fund’s net asset value could decrease as a result of its investment activities and may be a greater risk to investors expecting to sell their Common Stock in a relatively short period following completion of this offering. Whether investors will realize gains or losses upon the sale of the Common Stock will depend not upon the Fund’s net asset value but upon whether the market price of the Common Stock at the time of sale is above or below the investor’s purchase price for the Common Stock.
Because the market price of the Common Stock will be determined by factors such as relative supply of and demand for the Common Stock in the market, general market and economic conditions and other factors beyond the control of the Fund, the Fund cannot predict whether the Common Stock will trade at, above or below net asset value or at, above or below the initial public offering price. The Fund’s Common Stock is designed primarily for long term investors and you should not view the Fund as a vehicle for trading purposes.
Portfolio Turnover Risk. Changes to the investments of the Fund may be made regardless of the length of time particular investments have been held. A high portfolio turnover rate may result in increased transaction costs for the Fund in the form of increased dealer spreads and other transactional costs, which may have an adverse impact on the Fund’s performance. The portfolio turnover rate of the Fund will vary from year to year, as well as within a year.

Summary of information regarding the Fund (unaudited) (cont’d)
Non-Diversification Risk. The Fund is classified as “non-diversified” under the 1940 Act. As a result, it can invest a greater portion of its assets in obligations of a single issuer than a “diversified” fund. The Fund may therefore be more susceptible than a diversified fund to being adversely affected by any single corporate, economic, political or regulatory occurrence. The Fund intends to qualify for the special tax treatment available to “regulated investment companies” under Subchapter M of the Code, and thus intends to satisfy the diversification requirements of Subchapter M, including the less stringent diversification requirement that applies to the percent of its total assets that are represented by cash and cash items (including receivables), U.S. government securities, the securities of other regulated investment companies and certain other securities.
Anti-Takeover Provisions Risk. The Charter and Bylaws of the Fund include provisions that are designed to limit the ability of other entities or persons to acquire control of the Fund for short-term objectives, including by converting the Fund to open-end status or changing the composition of the Board, that may be detrimental to the Fund’s ability to achieve its primary investment objective of providing current income. The Bylaws also contain a provision providing that the Board of Directors has adopted a resolution to opt in the Fund to the provisions of the Maryland Control Share Acquisition Act (“MCSAA”). There can be no assurance, however, that such provisions will be sufficient to deter professional arbitrageurs that seek to cause the Fund to take actions that may not be consistent with its investment objective or aligned with the interests of long-term shareholders, such as liquidating debt investments prior to maturity, triggering taxable events for shareholders and decreasing the size of the Fund. Such provisions may limit the ability of shareholders to sell their shares at a premium over prevailing market prices by discouraging an investor from seeking to obtain control of the Fund.
Temporary Defensive Strategies Risk. When Western Asset anticipates unusual market or other conditions, the Fund may temporarily depart from its principal investment strategies as a defensive measure and invest all or a portion of its assets in cash or short-term fixed-income securities. To the extent that the Fund invests defensively, it may not achieve its investment objectives.
Operational Risk. The valuation of the Fund’s investments may be negatively impacted because of the operational risks arising from factors such as processing errors and human errors, inadequate or failed internal or external processes, failures in systems and technology, changes in personnel, and errors caused by third party service providers or trading counterparties. It is not possible to identify all of the operational risks that may affect the Fund or to develop processes and controls that completely eliminate or mitigate the occurrence of such failures. The Fund and its shareholders could be negatively impacted as a result.

70
Western Asset Investment Grade Opportunity Trust Inc.

Cybersecurity Risk. Like other funds and business enterprises, the fund, the manager, the subadvisers and their service providers are subject to the risk of cyber incidents occurring from time to time. Cybersecurity incidents, whether intentionally caused by third parties or otherwise, may allow an unauthorized party to gain access to fund assets, fund or customer data (including private shareholder information) or proprietary information, cause the fund, the manager, the subadvisers and/or their service providers (including, but not limited to, fund accountants, custodians, sub-custodians, transfer agents and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality, or prevent fund investors from purchasing, redeeming or exchanging shares, receiving distributions or receiving timely information regarding the fund or their investment in the fund. The fund, the manager, and the subadvisers have limited ability to prevent or mitigate cybersecurity incidents affecting third party service providers, and such third party service providers may have limited indemnification obligations to the fund, the manager, and/or the subadvisers. Cybersecurity incidents may result in financial losses to the fund and its shareholders, and substantial costs may be incurred in order to prevent or mitigate any future cybersecurity incidents. Issuers of securities in which the fund invests are also subject to cybersecurity risks, and the value of these securities could decline if the issuers experience cybersecurity incidents.
New ways to carry out cyber attacks continue to develop. There is a chance that some risks have not been identified or prepared for, or that an attack may not be detected, which puts limitations on the fund’s ability to plan for or respond to a cyber attack.
More Information
For a complete list of the Fund’s fundamental investment restrictions and more detailed descriptions of the Fund’s investment policies, strategies and risks, see the Fund’s registration statement on Form N-2 that was declared effective by the SEC on June 25, 2009, as amended or superseded by subsequent disclosures. The Fund’s fundamental investment restrictions may not be changed without the approval of the holders of a majority of the outstanding voting securities, as defined in the 1940 Act.

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 stock- holders (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 P.O. Box 43006, Providence, RI 02940-3078 or by calling the Plan Agent at 1-888-888-0151. Such withdrawal will be effective immediately if notice is received by the Plan Agent not less than ten business days prior to any dividend or distribution record date; otherwise such withdrawal will be effective as soon as practicable after the Plan Agent’s investment of the most recently declared dividend or distribution on the Common Stock.

72
Western Asset Investment Grade Opportunity Trust Inc.

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 P.O. Box 43006, Providence, RI 02940-3078 or by calling the Plan Agent at 1-888-888-0151.

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.

Western Asset Investment Grade Opportunity Trust 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.

Western Asset Management Company, LLC

Proxy Voting Policies and Procedures

 

Western Asset Management Company, LLC

Proxy Voting Policies and Procedures

 

NOTE

 

The policy below relating to proxy voting and corporate actions is a global policy for Western Asset Management Company, LLC (“Western Asset” or the “Firm”) and all Western Asset affiliates, including Western Asset Management Company Limited (“Western Asset Limited”), Western Asset Management Company Ltd (“Western Asset Japan”) and Western Asset Management Company Pte. Ltd. (“Western Asset Singapore”), as applicable. As compliance with the policy is monitored by Western Asset, the policy has been adopted from the US Compliance Manual and all defined terms are those defined in the US Compliance Manual rather than the compliance manual of any other Western Asset affiliate.

 

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 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, for instance, when fixed income securities are converted into equity by their terms or in connection with a bankruptcy or corporate workout. 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 Rule 206(4)-6 under the 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 Franklin Resources (Franklin Resources includes Franklin Resources, Inc. and organizations operating as Franklin Resources) or any of its affiliates (other than Western Asset affiliated companies) regarding the voting of any securities owned by its clients.

 

PROCEDURES

Responsibility and Oversight

 

The Legal & Compliance Group is responsible for administering and overseeing the proxy voting process. The gathering of proxies is coordinated through the Corporate Actions team of the Investment Operations Group (“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 Portfolio Compliance Group 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 Portfolio Compliance Group for coordination and the following actions:

 

Proxies are reviewed to determine accounts impacted.

Impacted accounts are checked to confirm Western Asset voting authority.

Where appropriate, the Regulatory Affairs Group reviews the issues presented 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.

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

 

Portfolio Compliance Group 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’s Legal and Compliance Department 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 Rule 204-2 of the Advisers Act and ERISA DOL Bulletin 94-2. These records include:

 

A copy of Western Asset’s proxy voting policies and procedures.

 

Copies of proxy statements received with respect to securities in client accounts.

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:

 

1.Issuer name;
   
2.Exchange ticker symbol of the issuer’s shares to be voted;
   
3.Committee on Uniform Securities Identification Procedures (“CUSIP”) number for the shares to be voted;
   
4.A brief identification of the matter voted on;
   
5.Whether the matter was proposed by the issuer or by a shareholder of the issuer;
   
6.Whether a vote was cast on the matter;
   
7.A record of how the vote was cast;
   
8.Whether the vote was cast for or against the recommendation of the issuer’s management team;
   
9.Funds are required to categorize their votes so that investors can focus on the topics they find important. Categories include, for example, votes related to director elections, extraordinary transactions, say-on-pay, shareholder rights and defenses, and the environment or climate, among others; and
   
10.Funds are required to disclose the number of shares voted or instructed to be cast, as well as the number of shares loaned but not recalled and, therefore, not voted by the fund.
   

Records are maintained in an easily accessible place for a period of not less than five (5) years with the first two (2) years in Western Asset’s offices.

 

Disclosure

 

Western Asset’s proxy policies and procedures are described in the Firm’s Form ADV Part 2A. Clients are provided with a copy of these policies and procedures upon request. In addition, clients may receive reports on how their proxies have been voted, upon request.

 

Conflicts of Interest

 

All proxies that potentially present conflicts of interest are reviewed by the Regulatory Affairs Group for a materiality assessment. Issues to be reviewed include, but are not limited to:

 

1.Whether Western Asset (or, to the extent required to be considered by applicable law, its affiliates) manages assets for the company or an employee group of the company or otherwise has an interest in the company;
   
2.Whether Western Asset or an officer or director of Western Asset or the applicable portfolio manager or analyst responsible for recommending the proxy vote (together, “Voting Persons”) is a close relative of or has a personal or business relationship with an executive, director or person who is a candidate for director of the company or is a participant in a proxy contest; and
   
3.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 are based 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.

 

Situations can arise in which more than one Western Asset client invests in instruments of the same issuer or in which a single client may invest in instruments of the same issuer but in multiple accounts or strategies. Multiple clients or the same client in multiple accounts or strategies may have different investment objectives, investment styles, or investment professionals involved in making decisions. While there may be differences, votes are always cast in the best interests of the client and the investment objectives agreed with Western Asset. As a result, there may be circumstances where Western Asset casts different votes on behalf of different clients or on behalf of the same client with multiple accounts or strategies.

 

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

 

 

I.Board Approved Proposals

 

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

 

1.Matters relating to the Board of Directors

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

 

a.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.
   
b.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.
   
c.Votes are withheld for any nominee for director who attends less than 75% of board and committee meetings without valid reasons for absences.
   
d.Votes are cast on a case-by-case basis in contested elections of directors.
   
2.Matters relating to Executive Compensation

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

 

a.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.
   
b.Western Asset votes against stock option plans or proposals that permit replacing or repricing of underwater options.
   
c.Western Asset votes against stock option plans that permit issuance of options with an exercise price below the stock’s current market price.
   
d.Except where the firm is otherwise withholding votes for the entire board of directors, Western Asset votes for employee stock purchase plans that limit the discount for shares purchased under the plan to no more than 15% of their market value, have an offering period of 27 months or less and result in dilution of 10% or less.
   
3.Matters relating to Capitalization

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

 

a.Western Asset votes for proposals relating to the authorization of additional common stock.
   
b.Western Asset votes for proposals to effect stock splits (excluding reverse stock splits).
   
c.Western Asset votes for proposals authorizing share repurchase programs.
   
4.Matters relating to Acquisitions, Mergers, Reorganizations and Other Transactions

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

 

 

5.Matters relating to Anti-Takeover Measures

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

 

a.Western Asset votes on a case-by-case basis on proposals to ratify or approve shareholder rights plans.
   
b.Western Asset votes on a case-by-case basis on proposals to adopt fair price provisions.
   
6.Other Business Matters

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

 

a.Western Asset votes on a case-by-case basis on proposals to amend a company’s charter or bylaws.
   
b.Western Asset votes against authorization to transact other unidentified, substantive business at the meeting.
   
7.Reporting of Financially Material Information

Western Asset generally believes issuers should disclose information that is material to their business. What qualifies as “material” can vary, so votes are cast on a case-by-case basis but consistent with the overarching principle.

 

II.Shareholder Proposals

 

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

 

1.Western Asset votes for shareholder proposals to require shareholder approval of shareholder rights plans.
   
2.Western Asset votes for shareholder proposals that are consistent with Western Asset’s proxy voting guidelines for board-approved proposals.
   
3.Western Asset votes on a case-by-case basis on other shareholder proposals where the firm is otherwise withholding votes for the entire board of directors.
   

Environmental or social issues that are the subject of a proxy vote will be considered on a case-by-case basis. Constructive proposals that seek to advance the health of the issuer and the prospect for risk-adjusted returns to Western Assets clients are viewed more favorably than proposals that advance a single issue or limit the ability of management to meet its operating objectives.

 

III.Voting Shares of Investment Companies

 

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

 

1.Western Asset votes on a case-by-case basis on proposals relating to changes in the investment objectives of an investment company taking into account the original intent of the fund and the role the fund plays in the clients’ portfolios.
   
2.Western Asset votes on a case-by-case basis all proposals that would result in increases in expenses (e.g., proposals to adopt 12b-1 plans, alter investment advisory arrangements or approve fund mergers) taking into account comparable expenses for similar funds and the services to be provided.
   
IV.Voting Shares of Foreign Issuers

 

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

 

1.Western Asset votes for shareholder proposals calling for a majority of the directors to be independent of management.
   
2.Western Asset votes for shareholder proposals seeking to increase the independence of board nominating, audit and compensation committees.
   
3.Western Asset votes for shareholder proposals that implement corporate governance standards similar to those established under U.S. federal law and the listing requirements of U.S. stock exchanges, and that do not otherwise violate the laws of the jurisdiction under which the company is incorporated.
   
4.Western Asset votes on a case-by-case basis on proposals relating to (1) the issuance of common stock in excess of 20% of a company’s outstanding common stock where shareholders do not have preemptive rights, or (2) the issuance of common stock in excess of 100% of a company’s outstanding common stock where shareholders have preemptive rights.
   
V.Environmental, Social and Governance (“ESG”) Matters

 

Western Asset incorporates ESG considerations, among other relevant risks, as part of the overall process where appropriate. The Firm seeks to identify and consider material risks to the investment thesis, including material risks presented by ESG factors. While Western Asset is primarily a fixed income manager, opportunities to vote proxies are considered on the investment merits of the instruments and strategies involved.

 

As a general proposition, Western Asset votes to encourage disclosure of information material to their business. This principle extends to ESG matters. What qualifies as “material” can vary, so votes are cast on a case-by-case basis but consistent with the overarching principle. Western Asset recognizes that objective standards and criteria may not be available or universally agreed and that there may be different views and subjective analysis regarding factors and their significance.

 

Targeted environmental or social issues that are the subject of a proxy vote will be considered on a case-by-case basis. Constructive proposals that seek to advance the health of the issuer and the prospect for risk-adjusted returns to Western Assets clients are viewed more favorably than proposals that advance a single issue or limit the ability of management to meet its operating objectives.

 

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 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 Department of Labor has determined that the responsibility remains with the investment manager.

 

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

(a)(3): As of November 30, 2024:

 

Investment Professional Compensation

 

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 1940 Act and Rule 204A-1 under the Advisers Act 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.

 

Investment Professional Compensation

 

With respect to the compensation of the Fund’s investment professionals, the Subadviser’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 the 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 and 5 years having a larger 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 Fund) 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 investment professionals are eligible for additional incentives in recognition of outstanding performance. These are determined based upon the factors described above and include long-term incentives that vest over a set period of time past the award date.

Code of Ethics for Principal Executives & Senior Financial Officers

 

   
Procedures Revised [September 27, 2024]
   

 

 

FRANKLIN TEMPLETON AFFILIATED FUNDS

 

CODE OF ETHICS FOR PRINCIPAL EXECUTIVES AND

 

SENIOR FINANCIAL OFFICERS

 

I.Covered Officers and Purpose of the Code

 

This code of ethics (the “Code”) applies to the Principal Executive Officers, Principal Financial Officer and Principal Accounting Officer (the “Covered Officers”) of each investment company advised by a Franklin Resources subsidiary and that is registered with the United States Securities & Exchange Commission (“SEC”) (collectively, “FT Funds”) for the purpose of promoting:

 

Honest and ethical conduct, including the ethical resolution of actual or apparent conflicts of interest between personal and professional relationships;

 

Full, fair, accurate, timely and understandable disclosure in reports and documents that a registrant files with, or submits to, the SEC and in other public communications made by or on behalf of the FT Funds;

 

Compliance with applicable laws and governmental rules and regulations;

 

The prompt internal reporting of violations of the Code to an appropriate person or persons identified in the Code; and

 

Accountability for adherence to the Code.

 

Each Covered Officer will be expected to adhere to a high standard of business ethics and must be sensitive to situations that may give rise to actual as well as apparent conflicts of interest.

 

* Rule 38a-1 under the Investment Company Act of 1940 (“1940 Act”) and Rule 206(4)-7 under the Investment Advisers Act of 1940 (“Advisers Act”) (together the “Compliance Rule”) require registered investment companies and registered investment advisers to, among other things, adopt and implement written policies and procedures reasonably designed to prevent violations of the federal securities laws (“Compliance Rule Policies and Procedures”).

 

 

II.Other Policies and Procedures

This Code shall be the sole code of ethics adopted by the Funds for purposes of Section 406 of the Sarbanes-Oxley Act and the rules and forms applicable to registered investment companies thereunder.

 

Franklin Resources, Inc. has separately adopted the Code of Ethics and Business Conduct (“Business Conduct”), which is applicable to all officers, directors and employees of Franklin Resources, Inc., including Covered Officers. It summarizes the values, principles and business practices that guide the employee’s business conduct and also provides a set of basic principles to guide officers, directors and employees regarding the minimum ethical requirements expected of them. It supplements the values, principles and business conduct identified in the Code and other existing employee policies.

Additionally, the Franklin Templeton Funds have separately adopted the FTI Personal Investments and Insider Trading Policy governing personal securities trading and other related matters. The Code for Insider Trading provides for separate requirements that apply to the Covered Officers and others, and therefore is not part of this Code.

 

Insofar as other policies or procedures of Franklin Resources, Inc., the Funds, the Funds’ adviser, principal underwriter, or other service providers govern or purport to govern the behavior or activities of the Covered Officers who are subject to this Code, they are superseded by this Code to the extent that they overlap or conflict with the provisions of this Code. Please review these other documents or consult with the Legal Department if have questions regarding the applicability of these policies to you.

III.Covered Officers Should Handle Ethically Actual and Apparent Conflicts of Interest

Overview. A “conflict of interest” occurs when a Covered Officer’s private interest interferes with the interests of, or his or her service to, the FT Funds. For example, a conflict of interest would arise if a Covered Officer, or a member of his family, receives improper personal benefits as a result of a position with the FT Funds.

 

Certain conflicts of interest arise out of the relationships between Covered Officers and the FT Funds and already are subject to conflict of interest provisions in the Investment Company Act of 1940 (“Investment Company Act”) and the Investment Advisers Act of 1940 (“Investment Advisers Act”). For example, Covered Officers may not individually engage in certain transactions (such as the purchase or sale of securities or other property) with the FT Funds because of their status as “affiliated persons” of the FT Funds. The FT Funds’ and the investment advisers’ compliance programs and procedures are designed to prevent, or identify and correct, violations of these provisions. This Code does not, and is not intended to, repeat or replace these programs and procedures, and such conflicts fall outside of the parameters of this Code.

 

Although typically not presenting an opportunity for improper personal benefit, conflicts arise from, or as a result of, the contractual relationship between the FT Funds, the investment advisers and the fund administrator of which the Covered Officers are also officers or employees. As a result, this Code recognizes that the Covered Officers will, in the normal course of their duties (whether formally for the FT Funds, for the adviser, the administrator, or for all three), be involved in establishing policies and implementing decisions that will have different effects on the

2 

 

adviser, administrator and the FT Funds. The participation of the Covered Officers in such activities is inherent in the contractual relationship between the FT Funds, the adviser, and the administrator and is consistent with the performance by the Covered Officers of their duties as officers of the FT Funds. Thus, if performed in conformity with the provisions of the Investment Company Act and the Investment Advisers Act, such activities will be deemed to have been handled ethically. In addition, it is recognized by the FT Funds’ Boards of Directors (“Boards”) that the Covered Officers may also be officers or employees of one or more other investment companies covered by this or other codes.

 

Other conflicts of interest are covered by the Code, even if such conflicts of interest are not subject to provisions in the Investment Company Act and the Investment Advisers Act. The following list provides examples of conflicts of interest under the Code, but Covered Officers should keep in mind that these examples are not exhaustive. The overarching principle is that the personal interest of a Covered Officer should not be placed improperly before the interest of the FT Funds.

Each Covered Officer must:

Not use his or her personal influence or personal relationships improperly to influence investment decisions or financial reporting by the FT Funds whereby the Covered Officer would benefit personally to the detriment of the FT Funds;

 

Not cause the FT Funds to take action, or fail to take action, for the individual personal benefit of the Covered Officer rather than the benefit of the FT Funds;

 

Not retaliate against any other Covered Officer or any employee of the FT Funds or their affiliated persons for reports of potential violations that are made in good faith;

 

Report at least annually the following affiliations or other relationships:1

 

all directorships for public companies and all companies that are required to file reports with the SEC;

 

any direct or indirect business relationship with any independent directors of the FT Funds; 

 

any direct or indirect business relationship with any independent public accounting firm (which are not related to the routine issues related to the firm’s service as the Covered Persons accountant); and

 

any direct or indirect interest in any transaction with any FT Fund that will benefit the officer (not including benefits derived from the advisory, sub-advisory, distribution or service agreements with affiliates of Franklin Resources).

 

These reports will be reviewed by the Legal Department for compliance with the Code.

There are some conflict of interest situations that should always be approved in writing by Franklin Resources General Counsel or Deputy General Counsel, if material. Examples of these include2:

 

Service as a director on the board of any public or private Company.
   
The receipt of any gifts in excess of $100 from any person, from any corporation or association.

 

 

1 Reporting of these affiliations or other relationships shall be made by completing the annual Directors and Officers Questionnaire and returning the questionnaire to Franklin Resources Inc, General Counsel or Deputy General Counsel.

 

2 Any activity or relationship that would present a conflict for a Covered Officer may also present a conflict for the Covered Officer if a member of the Covered Officer’s immediate family engages in such an activity or has such a relationship. The Covered Person should also obtain written approval by FT’s General Counsel in such situations.

3 

 

The receipt of any entertainment from any Company with which the FT Funds has current or prospective business dealings unless such entertainment is business related, reasonable in cost, appropriate as to time and place, and not so frequent as to raise any question of impropriety. Notwithstanding the foregoing, the Covered Officers must obtain prior approval from the Franklin Resources General Counsel for any entertainment with a value in excess of $1000.
   
Any ownership interest in, or any consulting or employment relationship with, any of the FT Fund’s service providers, other than an investment adviser, principal underwriter, administrator or any affiliated person thereof.
   
A direct or indirect financial interest in commissions, transaction charges or spreads paid by the FT Funds for effecting portfolio transactions or for selling or redeeming shares other than an interest arising from the Covered Officer’s employment, such as compensation or equity ownership.
   
Franklin Resources General Counsel or Deputy General Counsel, or the Chief Compliance Officer, will provide a report to the FT Funds Audit Committee of any approvals granted at the next regularly scheduled meeting.
IV.Disclosure and Compliance
  
Each Covered Officer should familiarize himself with the disclosure requirements generally applicable to the FT Funds;
   
Each Covered Officer should not knowingly misrepresent, or cause others to misrepresent, facts about the FT Funds to others, whether within or outside the FT Funds, including to the FT Funds’ directors and auditors, and to governmental regulators and self-regulatory organizations;
   
Each Covered Officer should, to the extent appropriate within his or her area of responsibility, consult with other officers and employees of the FT Funds, the FT Fund’s adviser and the administrator with the goal of promoting full, fair, accurate, timely and understandable disclosure in the reports and documents the FT Funds file with, or submit to, the SEC and in other public communications made by the FT Funds; and
   
It is the responsibility of each Covered Officer to promote compliance with the standards and restrictions imposed by applicable laws, rules and regulations.

 

V.Reporting and Accountability

Each Covered Officer must:

 

Upon becoming a covered officer affirm in writing to the Board that he or she has received, read, and understands the Code (see Exhibit A);
   
Annually thereafter affirm to the Board that he has complied with the requirements of the Code; and
   
Notify Franklin Resources’ General Counsel or Deputy General Counsel promptly if he or she knows of any violation of this Code. Failure to do so is itself is a violation of this Code.
4 

 

Franklin Resources’ General Counsel and Deputy General Counsel are responsible for applying this Code to specific situations in which questions are presented under it and have the authority to interpret this Code in any particular situation.3 However, the Independent Directors of the respective FT Funds will consider any approvals or waivers4 sought by any Chief Executive Officers of the Funds.

 

The FT Funds will follow these procedures in investigating and enforcing this Code:

Franklin Resources General Counsel or Deputy General Counsel will take all appropriate action to investigate any potential violations reported to the Legal Department;
   
If, after such investigation, the General Counsel or Deputy General Counsel believes that no violation has occurred, The General Counsel is not required to take any further action;
   
Any matter that the General Counsel or Deputy General Counsel believes is a violation will be reported to the Independent Directors of the appropriate FT Fund;
   
If the Independent Directors concur that a violation has occurred, it will inform and make a recommendation to the Board of the appropriate FT Fund or Funds, which will consider appropriate action, which may include review of, and appropriate modifications to, applicable policies and procedures; notification to appropriate personnel of the investment adviser or its board; or a recommendation to dismiss the Covered Officer;
   
The Independent Directors will be responsible for granting waivers, as appropriate; and
   
Any changes to or waivers of this Code will, to the extent required, are disclosed as provided by SEC rules.5
VI.Other Policies and Procedures

This Code shall be the sole code of ethics adopted by the FT Funds for purposes of Section 406 of the Sarbanes-Oxley Act and the rules and forms applicable to registered investment companies thereunder. Insofar as other policies or procedures of the FT Funds, the FT Funds’ advisers, principal underwriter, or other service providers govern or purport to govern the behavior or activities of the Covered Officers who are subject to this Code, they are superseded by this Code to the extent that they overlap or conflict with the provisions of this Code. The FTI Personal Investments and Insider Trading Policy, adopted by the FT Funds, FT investment advisers and FT Fund’s principal underwriter pursuant to Rule 17j-1 under the Investment Company Act, the Code of Ethics and Business Conduct and more detailed policies and procedures set forth in FT’s Employee Handbook are separate requirements applying to the Covered Officers and others, and are not part of this Code.

VII.Amendments

Any amendments to this Code must be approved or ratified by a majority vote of the FT Funds’ Board including a majority of independent directors.

 

 

3 Franklin Resources General Counsel and Deputy General Counsel are authorized to consult, as appropriate, with members of the Audit Committee, counsel to the FT Funds and counsel to the Independent Directors, and are encouraged to do so.

 

4 Item 2 of Form N-CSR defines “waiver” as “the approval by the registrant of a material departure from a provision of the code of ethics” and “implicit waiver,” which must also be disclosed, as “the registrant’s failure to take action within a reasonable period of time regarding a material departure from a provision of the code of ethics that has been made known to an executive officer” of the registrant. See Part X.

 

5 See Part X.

VIII.Confidentiality

All reports and records prepared or maintained pursuant to this Code will be considered confidential and shall be maintained and protected accordingly. Except as otherwise required by law or this Code, such matters shall not be disclosed to anyone other than the FT Funds’ Board and their counsel.

IX.Internal Use

The Code is intended solely for the internal use by the FT Funds and does not constitute an admission, by or on behalf of any FT Funds, as to any fact, circumstance, or legal conclusion.

X.Disclosure on Form N-CSR

Item 2 of Form N-CSR requires a registered management investment company to disclose annually whether, as of the end of the period covered by the report, it has adopted a code of ethics that applies to the registrant’s principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions, regardless of whether these officers are employed by the registrant or a third party. If the registrant has not adopted such a code of ethics, it must explain why it has not done so.

The registrant must also: (1) file with the SEC a copy of the code as an exhibit to its annual report; (2) post the text of the code on its Internet website and disclose, in its most recent report on Form N-CSR, its Internet address and the fact that it has posted the code on its Internet website; or (3) undertake in its most recent report on Form N-CSR to provide to any person without charge, upon request, a copy of the code and explain the manner in which such request may be made. Disclosure is also required of amendments to, or waivers (including implicit waivers) from, a provision of the code in the registrant’s annual report on Form N-CSR or on its website. If the registrant intends to satisfy the requirement to disclose amendments and waivers by posting such information on its website, it will be required to disclose its Internet address and this intention.

The Legal Department shall be responsible for ensuring that:

 

a copy of the Code is filed with the SEC as an exhibit to each Fund’s annual report; and
   
any amendments to, or waivers (including implicit waivers) from, a provision of the Code is disclosed in the registrant’s annual report on Form N-CSR.

In the event that the foregoing disclosure is omitted or is determined to be incorrect, the Legal Department shall promptly file such information with the SEC as an amendment to Form N-CSR.

In such an event, the Fund Chief Compliance Officer shall review the Code and propose such changes to the Code as are necessary or appropriate to prevent reoccurrences.
