Fund overview

Q. What is the Fund’s investment strategy?

A. The Fund’s primary investment objective is to seek a high level of current income, consistent with prudent investment risk, through investment in a diversified portfolio of debt securities. To a lesser extent, the Fund may also invest in privately placed debt securities and in certain equity securities. Capital appreciation is a secondary investment objective.

The Fund invests at least 80% of its net assets in fixed income securities that are rated in the Baa or BBB categories or above at the time of purchase by one or more Nationally Recognized Statistical Rating Organizations (NRSROs) or unrated securities of comparable quality at the time of purchase (as determined by the investment adviser). If 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. In addition, the Fund may invest up to 20% in other fixed income securities, and not more than 25% in securities restricted as to resale. The Fund’s 80% investment policy may be changed by the Board of Directors without shareholder approval upon 60 days’ prior notice to shareholders. In addition, convertible bonds and preferred securities may be treated as “fixed income” securities for purposes of the policy and so, if appropriately rated, would qualify for the 80% test.

At Western Asset Management Company, LLC (Western Asset), the Fund’s investment adviser, we utilize a fixed income team approach, with decisions derived from interaction among various investment management sector specialists. The sector teams are comprised of Western Asset’s senior portfolio management personnel, research analysts and an in-house economist. Under this team approach, management of client fixed income portfolios will reflect a consensus of interdisciplinary views within the Western Asset organization. The individuals responsible for development of investment strategy, day-to-day portfolio management, oversight and coordination of the Fund are Michael C. Buchanan, Dan Alexander, Ryan K. Brist, 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 and generated a modest gain over the twelve-months ended December 31, 2024. The market was driven by several factors, including resilient economic growth, moderating inflation, shifting U.S. Federal Reserve (Fed) monetary policy, election results, and several geopolitical issues.

Short-term U.S. Treasury yields edged modestly higher over the year. The Fed lowered interest rates in September 2024 (the first reduction since 2020) and again in November and December 2024. The December 2024 reduction put the federal funds target rate at 4.25%-4.50%, the lowest level since December 2022. However, with the job market appearing to stabilize and expectations of pro-growth and potentially inflationary policies under President-elect Donald Trump, the Fed suggested it would take a cautious approach to future rate cuts. The December 2024 Summary of Economic Projections showed that Fed officials now anticipate lowering rates twice for a total of 50 basis points in 2025. In

Western Asset Investment Grade Income Fund Inc. 2024 Annual Report

Fund overview (cont’d)

contrast, at its September 2024 meeting the central bank anticipated four rate cuts in 2025, totaling 100 basis points.

The two-year Treasury yield began the reporting period at 4.23% and ended the period at 4.25%. 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 moved sharply higher, largely driven by an increase in the fourth quarter of the period in part due to the Fed’s hawkish stance in terms of rate cuts in 2025. The ten-year Treasury yield began the reporting period at 3.88% and ended at 4.58%. 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 overall credit market, as represented by the Bloomberg U.S. Credit Indexi, returned 2.03% during the twelve-month reporting period ended December 31, 2024. Over the same period, the overall bond market, as measured by the Bloomberg U.S. Aggregate Indexii, returned 1.25%.

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

A. During the reporting period, several adjustments were made to the Fund’s portfolio. We tactically managed the Fund’s duration, trimming but maintaining a long-duration position relative to the benchmark. We ended the reporting period with a slightly lower duration than where we started. Additionally, we increased the Fund’s allocation to emerging market bonds, specifically U.S. dollar-denominated bonds. Conversely, we reduced the Fund’s allocation to investment-grade bonds in the industrial sector.

Performance review

For the twelve months ended December 31, 2024, Western Asset Investment Grade Income Fund Inc. returned 3.16% based on its net asset value (NAV)iii and 9.11% based on its New York Stock Exchange (NYSE) market price per share. The Fund’s unmanaged benchmarks, the Bloomberg U.S. Corporate High Yield Bond Indexiv and the Bloomberg U.S. Credit Index, returned 8.19% and 2.03%, respectively, 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 the Fund’s NAV. The Fund’s manager believes the practice helps maintain the Fund’s competitiveness and may benefit the Fund’s market price and premium/discount to the Fund’s NAV.

During the twelve-month period, the Fund made distributions to shareholders totaling $0.60 per share.* The performance table shows the Fund’s twelve-month total return based on its NAV and market price as of December 31, 2024. Past performance is no guarantee of future results.

For the tax character of distributions paid during the fiscal year ended December 31, 2024, please refer to page 43 of this report.

Accordingly, adjusted total returns have been disclosed in the Financial Highlights and differ from those reported here.

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

Q. What were the leading contributors to performance?

A. On a sector basis, an overweight position in financials sector contributed to relative performance as the sector outperformed during the reporting period. Issue selection within this sector was also a major contributor, led by overweight positions in Barclays and HSBC Holdings. Additionally, overweight positions in CI Financial and Charles Schwab was additive for results. On a quality basis, the portfolio’s tilt towards lower quality was beneficial to performance, as credit spreads were fair and overall corporate management remained conservative in the face of macroeconomic uncertainty.

Q. What were the leading detractors from performance?

A. Among the largest detractors from the Fund’s relative performance during the reporting period was its overweight duration positioning, as yields increased. On a sector basis, underweight positions in real estate investment trusts and utilities also had a negative impact, as these sectors outperformed during the reporting period.

RISKS: The Fund is a 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 NYSE. Similar to stocks, the Fund’s share price will fluctuate with market conditions and, at the time of sale, may be worth more or less than the original investment. Shares of closed-end funds often trade at a discount to their net asset value. Diversification does not assure against market loss. The Fund’s investments are subject to a number of risks, including interest rate, credit and inflation risks. As interest rates rise, bond prices fall, reducing the value of a fixed income investment’s price. The Fund may invest in high yield bonds (commonly known as “junk” bonds), which are rated below investment grade and carry more risk than higher-rated securities. To the extent that the Fund invests in asset-backed, mortgage-backed or mortgage-related securities, its exposure to prepayment and extension risks may be greater than investments in other fixed income securities. Leverage may result in greater volatility of NAV and the market price of the shares of the Fund’s common stock and increases a shareholder’s risk of loss. The Fund may invest, to a limited extent, in foreign securities, including emerging or developing markets. Investing in foreign securities is subject to certain risks not associated with domestic investing, such as currency fluctuations and social, political, and economic uncertainties which could result in significant volatility. These risks are magnified in emerging or developing markets. Emerging or developing market countries tend to have economic, political, and legal systems that are less developed and are less stable than those of more developed countries. The Fund may make significant investments in derivative instruments. Derivative instruments can be illiquid, may disproportionately increase losses, and have a potentially large impact on Fund performance. The 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 investment advisers. For more information on Fund risks, see Summary of information regarding the Fund - Principal Risk Factors in this report.

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

The Bloomberg U.S. Corporate High Yield Bond Index measures the U.S. dollar-denominated, high yield, fixed-rate corporate bond market. Securities are classified as high yield if the middle rating of Moody’s, Fitch and Standard & Poor’s is Ba1/BB+/BB+ or below. Bonds from issuers with an emerging markets country of risk, based on the index’s emerging markets country definition, are excluded.

Western Asset Investment Grade Income Fund Inc. 2024 Annual Report

Notes to financial statements

1. Organization and significant accounting policies

Western Asset Investment Grade Income Fund Inc. (the “Fund”) is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as a diversified, closed-end management investment company. The Fund’s primary investment objective is to seek a high level of current income, consistent with prudent investment risk, through investment in a diversified portfolio of debt securities. To a lesser extent, the Fund may also invest in privately placed debt securities and in certain equity securities. Capital appreciation is a secondary investment objective.

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 adviser to be unreliable, the market price may be determined by the adviser using quotations from one or more broker/dealers or at the transaction price if the security has recently been purchased and no value has yet been obtained from a pricing service or pricing broker. When reliable prices are not readily available, such as when the value of a security has been significantly affected by events after the close of the exchange or market on which the security is principally traded, but before the Fund calculates its net asset value, the Fund values these securities as determined in accordance with procedures approved by the Fund’s Board of Directors (the “Board”).

Pursuant to policies adopted by the Board, the Fund’s adviser has been designated as the valuation designee and is responsible for the oversight of the daily valuation process. The

Western Asset Investment Grade Income Fund Inc. 2024 Annual Report

Notes to financial statements (cont’d)

Fund’s adviser 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 adviser and the Board. 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, 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 quarterly.

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

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

•

Level 1 — 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.

Western Asset Investment Grade Income Fund Inc. 2024 Annual Report

Notes to financial statements (cont’d)

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

(c) Credit and market risk. The Fund invests in high-yield and emerging market instruments that are subject to certain credit and market risks. The yields of high-yield and emerging market debt obligations reflect, among other things, perceived credit and market risks. The Fund’s investments in securities rated below investment grade typically involve risks not associated with higher rated securities including, among others, greater risk related to timely and ultimate payment of interest and principal, greater market price volatility and less liquid secondary market trading. The consequences of political, social, economic or diplomatic changes may have disruptive effects on the market prices of investments held by the Fund. The Fund’s investments in non-U.S. dollar denominated securities may also result in foreign currency losses caused by devaluations and exchange rate fluctuations.

(d) 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.

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

Western Asset Investment Grade Income Fund Inc. 2024 Annual Report

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 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 December 31, 2024, the Fund did not have any open OTC derivative transactions with credit related contingent features in a net liability position.

(f) 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 for dividends received in cash and/or securities. The cost of investments sold is determined by use of the specific identification method. To the extent any issuer defaults or a credit event occurs that impacts the issuer, the Fund may halt any additional interest income accruals and consider the realizability of interest accrued up to the date of default or credit event.

(g) Distributions to shareholders. Distributions from net investment income of the Fund, if any, are declared quarterly and paid on a monthly basis. Distributions of net realized gains, if any, are declared at least annually. Distributions to shareholders of the Fund are recorded on the ex-dividend date and are determined in accordance with income tax regulations, which may differ from GAAP.

Western Asset Investment Grade Income Fund Inc. 2024 Annual Report

Notes to financial statements (cont’d)

(h) 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.

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

However, due to the timing of when distributions are made by the Fund, the Fund may be subject to an excise tax of 4% of the amount by which 98% of the Fund’s annual taxable income and 98.2% of net realized gains exceed the distributions from such taxable income and realized gains for the calendar year. During the year ended December 31, 2024, the Fund anticipates being subject to an excise tax of approximately $8,000 for the calendar year 2024, all of which was accrued as of December 31, 2024.

Management has analyzed the Fund’s tax positions taken on income tax returns for all open tax years and has concluded that as of December 31, 2024, no provision for income tax is required in the Fund’s financial statements. The Fund’s federal and state income and federal excise tax returns for tax years for which the applicable statutes of limitations have not expired are subject to examination by the Internal Revenue Service and state departments of revenue.

(j) Reclassification. GAAP requires that certain components of net assets be reclassified to reflect permanent differences between financial and tax reporting. These reclassifications have no effect on net assets or net asset value per share. During the current year, the Fund had no reclassifications.

2. Investment management agreement and other transactions with affiliates

The Fund has entered into an Investment Advisory Agreement with Western Asset Management Company, LLC (“Adviser”), pursuant to which the Adviser provides investment advice and administrative services to the Fund. In return for its services, the Fund pays the Adviser a monthly fee at an annual rate of 0.70% of the average monthly net assets of the Fund up to $60,000,000 and 0.40% of such net assets in excess of $60,000,000. If expenses (including the Adviser’s fee but excluding interest, taxes, brokerage fees, the expenses of any offering by the Fund of its securities, and extraordinary expenses beyond the control of the Fund) borne by the Fund in any fiscal year exceed 1.5% of average net assets of the Fund up to $30,000,000 and 1% of average net assets of the Fund over $30,000,000, the Adviser has contractually agreed to reimburse the Fund for any excess. The Adviser or its affiliates has also agreed to waive $24,000 annually in Fund operating expenses. This waiver is ongoing and will not be terminated without Board approval.

The Adviser 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”).

Western Asset Investment Grade Income Fund Inc. 2024 Annual Report

During the year ended December 31, 2024, fees waived and/or expenses reimbursed amounted to $24,767, which included an affiliated money market fund waiver of $767.

Western Asset Management Company Limited (“Western London”), as subadviser to the Fund, provides the Fund with investment research, advice, management and supervision and a continuous investment program for the Fund’s portfolio of non-dollar securities consistent with the Fund’s investment objectives and policies. As compensation, the Adviser pays Western London a fee based on the pro rata assets of the Fund managed by Western London during the month.

Under the terms of an administrative services agreement among the Fund, the Adviser, and Franklin Templeton Fund Adviser, LLC (“FTFA”), the Adviser (not the Fund) pays FTFA a monthly fee of $3,000 (an annual rate of $36,000).

The Adviser, FTFA and Western London are indirect, wholly-owned subsidiaries of Franklin Resources, Inc. (“Franklin Resources”).

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

†

Directors who are not “interested persons” of the Fund within the meaning of Section 2(a)(19) of the Investment Company Act of 1940, as amended (the “1940 Act”).

Each of the Directors of the Fund holds office until his or her successor shall have been duly elected and shall qualify, subject to prior death, resignation, retirement, disqualification or removal from office and applicable law and the rules of the New York Stock Exchange. Each officer holds office until his or her respective successor is chosen and qualified, or in each case until he or she sooner dies, resigns, is removed with or without cause or becomes disqualified.

Each board member also serves as a member of the Boards of Western Asset Inflation-Linked Opportunities & Income Fund, Western Asset Inflation-Linked Income Fund and Western Asset Premier Bond Fund (each a closed-end investment company) and the portfolios of Western Asset Funds, Inc., Legg Mason Partners Income Trust, Legg Mason Partners Institutional Trust, Legg Mason Partners Money Market Trust, Legg Mason Partners Premium Money Market Trust, Legg Mason Partners Variable Income Trust and Master Portfolio Trust (each an open-end investment company), which are all considered part of the same fund complex as the Fund.

Mr. Larson is the chief investment officer for William H. Gates III and in that capacity oversees the non-Microsoft investments of Mr. Gates and all of the investments of the Bill and Melinda Gates Foundation Trust (such combined investments are referred to as the “Accounts”). Since 1997, Western Asset has provided discretionary investment advice with respect to one or more Accounts. Since December 31, 2021, at no time did the value of those investment portfolios exceed 1.0% of Western Asset’s total assets under management. No changes to these arrangements are currently contemplated.

Western Asset and its affiliates provide investment advisory services with respect to registered investment companies sponsored by an affiliate of Pacific Mutual Holding Company (“Pacific Holdings”). Affiliates of Pacific Holdings receive compensation from FTFA or its affiliates for shareholder or distribution services provided with respect to registered investment companies for which Western Asset or its affiliates serve as investment adviser.

Mr. Olson is an “interested person” of the Fund, as defined in the 1940 Act, because his law firm has provided legal services to Western Asset.

Ms. Trust is an “interested person” of the Fund, as defined in the 1940 Act, because of her position with FTFA and/or certain of its affiliates.

Indicates the earliest year in which the officer took such office. Each officer of the Fund is an “interested person” (as defined above) of the Fund.

Investment Objectives

Principal Investment Policies and Strategies

The Fund invests at least 80% of its net assets in fixed income securities that are rated in the Baa or BBB categories or above at the time of purchase by one or more Nationally Recognized Statistical Rating Organizations (“NRSROs”) or unrated securities of comparable quality at the time of purchase (as determined by the Adviser). If 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. In addition, the Fund may invest up to 20% in other fixed income securities, and not more than 25% in securities restricted as to resale. In addition, convertible bonds and preferred securities may be treated as “fixed income” securities for purposes of the policy and so, if appropriately rated, would qualify for the 80% test. The Fund’s 80% investment policy may be changed by the Board of Directors without shareholder approval upon 60 days’ prior notice to shareholders.

At least 75% of the Fund’s total assets will be invested in the following types of interest-bearing debt securities:

(1) marketable and privately placed straight debt securities which are rated at the time of purchase within the four highest grades assigned by Moody’s Investors Service, Inc. (“Moody’s”) (Aaa, Aa, A or Baa) or S&P Global Ratings (“S&P”) (AAA, AA, A or BBB);

(2) marketable securities of, or guaranteed by, the U.S. Government, its agencies or instrumentalities;

(3) marketable securities (payable in U.S. dollars) of, or guaranteed by, the Government of Canada or a Province of Canada or any instrumentality or political subdivision thereof, acquired under circumstances that would not subject the Fund to payment of U.S. Interest Equalization Tax, such securities not to exceed 25% of the Fund’s total assets;

(4) obligations of, or guaranteed by, U.S. banks or U.S. bank holding companies (i.e., companies whose primary assets are U.S. banks), which obligations, although not rated as a matter of policy by either Moody’s or S&P, are considered by management to have investment quality comparable to securities which may be purchased under item (1) above, provided that investments will not be made in obligations of First Interstate Bancorp, First Interstate Bank of California or any of their subsidiaries; and

(5) commercial paper.

Western Asset Investment Grade Income Fund Inc.

Summary of information regarding the Fund (unaudited) (cont’d)

The foregoing requirement for 75% of total assets (the “75% policy”) is a fundamental policy of the Fund which may only be changed with the approval of the holders of the Fund’s voting securities as discussed below. In investing up to 75% of the Fund’s total assets in the debt securities (as described above) which are not rated, the Adviser selects securities which, in the opinion of the Adviser, are of a quality comparable to one of the four highest grades of debt securities which are rated.

Up to 25% of the Fund’s total assets may consist of:

(1) interest-bearing debt securities not included in items (1) through (5) above, which include straight debt securities rated below the four highest grades assigned by Moody’s or S&P (although the Adviser does not currently intend to invest in debt securities rated less than B by Moody’s or S&P), which securities lack desirable investment characteristics with assurance of interest and principal payments over any long period of time being small.

(2) securities which may be convertible into or exchangeable for, or carry warrants to purchase, common stock or other equity interests; and

(3) preferred stocks.

Trust preferred interests and capital securities are considered debt securities and not preferred stock for purposes of the foregoing policy and the 75% policy. The Fund will not invest for the purpose of exercising control or management.

The Fund may invest in securities of other investment companies to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”).

Subject to certain restrictions, the Fund may leverage its portfolio borrowing from banks or other lending institutions in negotiated transactions and issuing publicly or privately and from time to time, bonds, debentures or notes, in series or otherwise, with such interest rates and other terms and provisions, including conversion rights if deemed advisable, as the Board of Directors of the Fund may from time to time determine, provided that immediately after any such borrowing or issuance the aggregate amount of such indebtedness outstanding would not exceed 20% of the value of the Fund’s total assets. Subject to such limitations as may be specified in applicable margin regulations of the Board of Governors of the Federal Reserve System, amounts so borrowed and securities so issued by the Fund could be secured by a pledge or mortgage, provided that as a result not more than 40% of the value of the Fund’s total assets would be subject in the aggregate to such pledges and mortgages. Borrowings may be for long or short term, and, subject to compliance with applicable legal requirements, including applicable provisions of the 1940 Act, may be evidenced by documented discount notes or other short-term notes of the Fund generically referred to as “commercial paper.”

Western Asset Investment Grade Income Fund Inc.

Subject to certain requirements of the Securities and Exchange Commission (the “SEC”), the Fund may lend its portfolio securities to any broker, dealer or financial institution.

The Fund may invest in asset-backed securities. The Fund may also invest in mortgage-backed securities (“MBS”) such as mortgage pass-through securities, collateralized mortgage obligations and multi-class pass-through securities. The Fund may also invest in debt securities which are secured with collateral consisting of mortgage loans or MBS, and in other types of MBS. The Fund may also invest in mortgage pass-through securities issued by governmental, government-related and private entities which are stripped MBS (“SMBS”). As new types of MBS are developed and offered to investors, the Adviser will, consistent with the Fund’s investment objectives, policies and quality standards, consider making investments in such new types of mortgage-backed securities.

The Fund may invest in floating rate, inverse floating rate and index obligations whose interest payments or maturity values float with, or inversely to, an underlying index or price.

The Fund may invest in foreign securities. The Fund may enter into certain foreign currency transactions, including both “spot” purchases and sales, and forward foreign currency contracts. Typically, the Fund would not enter into a forward currency contract with a term of greater than one year, although it may on some occasions do so.

Investment Restrictions

Except as otherwise noted, the Fund’s investment objectives, strategies and investment policies are not fundamental and may be changed by the Board of Directors without the approval of the shareholders. The following investment restrictions are fundamental policies for the protection of the Fund’s shareholders and, subject to compliance with the requirements of the 1940 Act, may only be changed with the approval of the holders of the Fund’s voting securities as specified below and provide that the Fund will not:

1. Issue any senior securities (as defined in the 1940 Act), except in connection with borrowings permitted in Item 2 below or insofar as interest rate futures contracts as permitted by Item 17 below might be considered to be the issuance of a senior security.

2. Borrow any money except (a) as described under “Principal Investment Policies and Strategies” and (b) from banks for temporary or emergency purposes in an amount not exceeding 5% of the value of its total assets, provided, however, that without reference to such 5% limitation the Fund may enter into and hold interest rate futures contracts and may make deposits or have similar arrangements in connection therewith.

3. Mortgage, pledge or hypothecate its assets except (a) as described under “Principal Investment Policies and Strategies” and (b) that up to 15% of the value of its assets may be security for temporary borrowing, provided, however, that this limitation shall not apply to deposits or similar arrangements made in connection with the entering into and

Western Asset Investment Grade Income Fund Inc.

Summary of information regarding the Fund (unaudited) (cont’d)

holding of interest rate futures contracts or to the writing of call options in an amount not to exceed 15% of the value of its assets.

4. Act as an underwriter, except to the extent that, in connection with the disposition of restricted portfolio securities, the Fund may be deemed to be an underwriter under applicable laws.

5. Purchase or sell real estate, except that the Fund may purchase or sell securities secured by real estate or interests therein or issued by companies, including real estate investment trusts, which own real estate or interests therein.

6. Purchase or sell commodities or commodity contracts, provided that the Fund may enter into and hold interest rate futures contracts and make deposits or have similar arrangements in connection therewith, and the Fund may write listed covered call options and buy and sell put and call options on debt securities in an amount not to exceed 15% of the value of its total assets.

7. Invest more than 5% of the value of its total assets in the securities of any one issuer (other than cash items and securities of the U.S. Government or its agencies or instrumentalities) or purchase more than 10% of any class of the outstanding voting securities of any one issuer.

8. Invest more than 25% of the value of its total assets in restricted securities, which are securities acquired in private placement transactions.

9. Concentrate its investments in any particular industry; however, it may invest up to 25% of the value of its total assets in the securities of issues in any one industry. As to utility companies, gas, electric, water and telephone companies will be considered as separate industries.

10. Invest more than 25% of the value of its total assets in securities of, or guaranteed by, the Government of Canada or a Province of Canada or any instrumentality or political subdivision thereof.

11. Purchase or retain the securities of any issuer, if, to the Fund’s knowledge, those officers or directors of the Fund or of its investment adviser who individually own beneficially more than 0.5% of the outstanding securities of such issuer, together own beneficially more than 5% of such outstanding securities.

12. Make loans to other persons, except for the purchase of debt securities in private placement transactions or public offerings in accordance with the Fund’s investment objectives and policies and for loans of portfolio securities subject to compliance with the requirements of the SEC.

Western Asset Investment Grade Income Fund Inc.

13. Purchase securities on margin, except that it may obtain such short-term credits as may be necessary for the clearance of purchases or sales of securities, provided that the Fund may enter into and hold interest rate futures contracts and may make deposits or have similar arrangements in connection therewith.

14. Participate on a joint or a joint and several basis in any securities trading account.

15. Invest in puts, calls or combinations thereof, provided that the Fund may enter into and hold interest rate futures contracts and make deposits or have similar arrangements in connection therewith, and the Fund may write listed covered call options and buy and sell put and call options on debt securities in an amount not to exceed 15% of the value of its total assets.

16. Make short sales, except for sales “against the box,” provided that the Fund may enter into and hold interest rate futures contracts and may make deposits or have similar arrangements in connection therewith.

17. Enter into and hold any interest rate futures contracts, if, immediately thereafter, the sum of (a) the then aggregate futures market prices of financial instruments required to be delivered under open futures contract sales of the Fund and (b) the aggregate purchase prices under open futures contract purchases of the Fund, would exceed 30% of the total assets of the Fund, at market value.

The foregoing fundamental policies may not be changed without approval of the holders of the lesser of (a) 67% of the Fund’s voting securities present at a meeting, if the holders of more than 50% of outstanding voting securities are present in person or by proxy, or (b) more than 50% of the Fund’s outstanding voting securities.

Any investment policy or restriction which involves a maximum percentage of securities or assets shall not be considered to be violated unless an excess over the percentage occurs immediately after an acquisition of securities and results therefrom. Securities received upon conversion or upon exercise of warrants and securities remaining upon the breakup of units or detachment of warrants may be retained to permit advantageous disposition.

Principal Risk Factors

The Fund is a 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 share price will fluctuate with market conditions and, at the time of sale, may be worth more or less than the original investment. Shares of closed-end funds often trade at a discount to their net asset value. Diversification does not assure against market loss.

Western Asset Investment Grade Income Fund Inc.

Summary of information regarding the Fund (unaudited) (cont’d)

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.

Market Discount Risk. 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. Whether investors will realize gains or losses upon the sale of shares of the Fund’s 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 shares of 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.

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:

• 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. 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 futures contracts, options on futures and options based on U.S. Treasury securities, for the purpose of reducing the interest rate sensitivity of the

Western Asset Investment Grade Income Fund Inc.

portfolio, although there is no assurance that it will do so or that such strategies will be successful. Recently, there have been inflationary price movements. As such, fixed income securities markets may experience heightened levels of interest rate volatility and liquidity risk.

• Prepayment Risk. Many issuers have a right to prepay their securities. 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 shareholders. 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.

• Extension Risk. When interest rates rise, repayments of fixed income securities, particularly asset- and mortgage- backed securities, may occur more slowly than anticipated, extending the effective duration of these fixed income securities at below market interest rates and causing their market prices to decline more than they would have declined due to the rise in interest rates alone. This may cause the Fund’s share price to be more volatile.

• Duration Risk. For the simplest fixed income securities, “duration” indicates the average time at which the security’s cash flows are to be received. For simple fixed income securities with interest payments occurring prior to the payment of principal, duration is always less than maturity. In general, the lower the stated or coupon rate of interest of a fixed income security, the closer its duration will be to its final maturity; conversely, the higher the stated or coupon rate of interest of a fixed income security, the shorter its duration will be compared to its final maturity.

Determining duration becomes more complex when fixed income security features like floating or adjustable coupon payments, optionality (for example, the right of the issuer to prepay or call the security), and structuring (for example, the right of the holders of certain securities to receive priority as to the issuer’s cash flows) are considered. The calculation of “effective duration” attempts to take into account optionality and other

Western Asset Investment Grade Income Fund Inc.

Summary of information regarding the Fund (unaudited) (cont’d)

complex features. Generally, the longer the effective duration of a security, the greater will be the expected change in the percentage price of the security with respect to a change in the security’s own yield. By way of illustration, a security with an effective duration of 3.5 years might normally be expected to go down in price by 35 bps if its yield goes up by 10 bps, while another security with an effective duration of 4.0 years might normally be expected to go down in price by 40 bps if its yield goes up by 10 bps. The assumptions that are made about a security’s features and options when calculating effective duration may prove to be incorrect. For example, many mortgage pass-through securities may have stated final maturities of 30 years, but current prepayment rates, which can vary widely under different economic conditions, may have a large influence on the pass-through security’s response to changes in yield. In these situations, the Fund’s portfolio manager may consider other analytical techniques that seek to incorporate the security’s additional features into the determination of its response to changes in its yield.

A security may change in price for a variety of reasons. For example, floating rate securities may have final maturities of ten or more years, but their effective durations will tend to be very short. If there is an adverse credit event, or a perceived change in the issuer’s creditworthiness, these securities could experience a far greater negative price movement than would be predicted by the change in the security’s yield in relation to its effective duration. As a result, investors should be aware that effective duration is not an exact measurement and may not reliably predict a security’s price sensitivity to changes in yield or interest rates.

Financials Sector Risk. The Fund may be susceptible to adverse economic or regulatory occurrences affecting the financial services sector. Financial services companies are subject to extensive government regulation and, as a result, their profitability may be affected by new regulations or regulatory interpretations. Unstable interest rates can have a disproportionate effect on the financial services sector and financial services companies whose securities the Fund may purchase may themselves have concentrated portfolios, which makes them vulnerable to economic conditions that affect that sector. Financial services companies have also been affected by increased competition, which could adversely affect the profitability or viability of such companies.

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 (meaning securities that rank below other securities with respect to claims on the issuer’s assets) are more likely to suffer

Western Asset Investment Grade Income Fund Inc.

a credit loss than non-subordinated securities of the same issuer and will be disproportionately affected by a default, downgrade or perceived decline in creditworthiness.

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 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.

Lower and Unrated Securities Risk. The Fund may invest in below investment grade securities (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.

Mortgage-backed and Asset-backed Securities Risk. When market interest rates increase, the market values of mortgage-backed securities decline. At the same time, mortgage refinancings and prepayments slow, which lengthens the effective duration of these securities. As a result, the negative effect of the interest rate increase on the market value of mortgage-backed securities is usually more pronounced than it is for other types of fixed income securities, potentially increasing the volatility of the Fund. Conversely, when market interest rates decline, while the value of mortgage-backed securities may increase, the rate of prepayment of the underlying mortgages also tends to increase, which shortens the effective duration of these securities. Mortgage-backed securities are also subject to the risk that underlying borrowers will be unable to meet their obligations and the value of property that secures the mortgage may decline in value and be insufficient, upon foreclosure, to repay the associated loan. Investments in asset-backed securities are subject to similar risks. The ability of an issuer of asset-backed securities to enforce its security interest in the underlying assets may be limited, and therefore certain asset-backed securities present a heightened level of risk.

Variable and Floating Rate Securities Risk. Variable rate securities reset at specified intervals, while floating rate securities reset whenever there is a change in a specified index rate. In most cases, these reset provisions reduce the impact of changes in market interest rates on the value of the security. However, the value of these securities may

Western Asset Investment Grade Income Fund Inc.

Summary of information regarding the Fund (unaudited) (cont’d)

decline if their interest rates do not rise as much, or as quickly, as other interest rates. Conversely, these securities will not generally increase in value if interest rates decline. The Fund may also invest in inverse floating rate debt instruments (“inverse floaters”). Interest payments on inverse floaters vary inversely with changes in interest rates. Inverse floaters pay higher interest (and therefore generally increase in value) when interest rates decline, and vice versa. An inverse floater may exhibit greater price volatility than a fixed rate obligation of similar credit quality.

Leverage Risk. The value of your investment may be more volatile if the Fund uses leverage through borrowing of money and, under certain circumstances, short sales, futures contracts, and other investment techniques. The Fund’s leveraging strategy may not be successful. Leverage is a speculative technique that may expose the Fund to greater risk and increased costs. Increases and decreases in the value of the Fund’s portfolio will be magnified when the Fund uses leverage. As a result, leverage will cause greater changes in the Fund’s net asset value than if leverage were not used. The Fund will also have to pay interest with respect to its leverage, which may reduce the Fund’s return. This expense may be greater than the Fund’s return on the underlying investments. It is anticipated that interest with respect to leverage will be based on shorter-term interest rates that would be periodically reset. There can be no assurance that the use of leverage will result in a higher yield on the shares. When leverage is employed, the net asset value and market price of the shares and the yield to shareholders will be more volatile. The use of leverage will cause the Fund’s net asset value to fall more sharply in response to increases in interest rates than it would in the absence of the use of leverage. Leverage creates two major types of risks for shareholders: the likelihood of greater volatility of net asset value and market price of the shares because changes in the value of the Fund’s assets, including investments bought with the proceeds from the use of leverage, are borne entirely by the shareholders; and the possibility either that net investment income will fall if the interest and dividend rates on leverage rise or that net investment income will fluctuate because the interest and dividend rates on leverage vary.

Foreign Securities and Emerging Markets 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 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

Western Asset Investment Grade Income Fund Inc.

are U.S. companies. The Public Company Accounting Oversight Board, which regulates auditors of U.S. public companies, is unable to inspect audit work papers in certain foreign countries. Investors in foreign countries often have limited rights and few practical remedies to pursue shareholder claims, including class actions or fraud claims, and the ability of the SEC, the U.S. Department of Justice and other authorities to bring and enforce actions against foreign issuers or foreign persons is limited. Foreign investments may also be adversely affected by U.S. government or international interventions, restrictions or economic sanctions, which could negatively affect the value of an investment or result in the Fund selling an investment at a disadvantageous time. 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 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.

Restricted Securities. Restricted securities are securities subject to legal or contractual restrictions on their resale, such as private placements. Such restrictions might prevent the sale of restricted securities at a time when the sale would otherwise be desirable. Under SEC regulations, certain restricted securities acquired through private placements can be traded freely among qualified purchasers. While restricted securities are generally presumed to be illiquid, it may be determined that a particular restricted security is liquid. Investing in these restricted securities could have the effect of increasing the Fund’s illiquidity if qualified purchasers become, for a time, uninterested in buying these securities.

Restricted securities may be sold only (1) pursuant to SEC Rule 144A or another exemption, (2) in privately negotiated transactions or (3) in public offerings with respect to which a registration statement is in effect under the 1933 Act. Rule 144A securities, although not registered in the U.S., may be sold to qualified institutional buyers in accordance with Rule 144A under the 1933 Act. As noted above, the Fund may determine that some Rule 144A securities are liquid. Where registration is required, the Fund may be obligated

Western Asset Investment Grade Income Fund Inc.

Summary of information regarding the Fund (unaudited) (cont’d)

to pay all or part of the registration expenses and a considerable period may elapse between the time of the decision to sell and the time the Fund may be permitted to sell a restricted security under an effective registration statement. If, during such a period, adverse market conditions were to develop, the Fund might obtain a less favorable price than prevailed when it decided to sell.

Illiquid securities may be difficult to value, and the Fund may have difficulty disposing of such securities promptly. The Fund does not consider non-U.S. securities to be restricted if they can be freely sold in the principal markets in which they are traded, even if they are not registered for sale in the U.S.

Foreign 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. The Fund may also engage in foreign currency transactions on a spot (cash) basis at the rate prevailing in the currency exchange market at the time of the transaction. In cases when a particular currency is difficult to hedge or difficult to hedge against the U.S. dollar, the Fund may seek to hedge against price movements in that currency by entering into transactions using options and futures contracts on foreign currencies and forward currency contracts (collectively, “Currency Instruments”), on another currency or a basket of currencies, the value of which Western Asset believes will have a high degree of positive correlation to the value of the currency being hedged. The risk that movements in the price of the Currency Instrument will not correlate perfectly with movements in the price of the currency subject to the hedging transaction is magnified when this strategy is used.

Derivatives Risk. 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

Western Asset Investment Grade Income Fund Inc.

governments have adopted and implemented 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.

Futures contracts require the Fund to deposit “initial margin” and may require the Fund to increase the level of its initial margin payment as a result of margin calls. If the Fund has insufficient cash to meet daily variation margin requirements, it might need to sell securities at a disadvantageous time or price. If the Fund were unable to liquidate a futures contract or an option on a futures position due to the absence of a liquid secondary market, the imposition of price limits or otherwise, it could incur substantial losses. The Fund would continue to be subject to market risk with respect to the position. In addition, except in the case of purchased options, the Fund would continue to be required to make daily variation margin payments and might be required to maintain the position being hedged by the future or option or to maintain cash or securities in a segregated account.

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 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.

Portfolio Turnover Risk. The length of time the Fund has held a particular security is not generally a consideration in investment decisions. A change in the securities held by the Fund is known as “portfolio turnover.” As a result of the Fund’s investment policies, under certain market conditions the Fund’s turnover rate may be higher than that of other investment companies. Portfolio turnover generally involves some expense to the Fund, including brokerage commissions or dealer mark-ups and other transaction costs on the sale of securities and reinvestment in other securities. These transactions may result in realization of taxable capital gains.

Higher portfolio turnover rates, such as those above 100%, are likely to result in higher brokerage commissions or other transaction costs and could give rise to a greater amount of taxable capital gains.

Western Asset Investment Grade Income Fund Inc.

Management Risk. The Fund is subject to management risk because it is an actively managed investment portfolio. Western Asset 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.

Inflation/Deflation Risk. Inflation risk is the risk that the Fund’s 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 Fund’s portfolio could decline. Shares of common stock and distributions on the shares of 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 shareholders. Deflation risk is the risk that prices throughout the economy may decline over time--the opposite of inflation. Deflation may have an adverse effect 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.

Investment in Other Investment Companies Risk. If the Fund acquires shares of investment companies, including ones affiliated with the Fund, shareholders bear both their proportionate share of expenses in the Fund (including management and advisory fees) and, indirectly, the expenses of the investment companies (to the extent not offset by Western Asset or its affiliates through waivers).

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 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, the value and liquidity of the Fund’s investments may be negatively affected. Following Russia’s invasion of Ukraine, 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

Western Asset Investment Grade Income Fund Inc.

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. Some sectors of the economy and individual issuers have experienced or may experience particularly large losses. Periods of extreme volatility in the financial markets, reduced liquidity of many instruments, increased government debt, inflation, and disruptions to supply chains, consumer demand and employee availability, may continue for some time. 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 may not work as intended, and have resulted in a large expansion of government deficits and debt, the long term consequences of which are not known. In addition, the COVID-19 pandemic, and measures taken to mitigate its effects, could result in disruptions to the services provided to the Fund by its service providers.

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 increased and may rise further. 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 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.

Western Asset Investment Grade Income Fund Inc.

Summary of information regarding the Fund (unaudited) (cont’d)

Liquidity Risk. Liquidity risk exists when particular investments are difficult to sell. Securities may become “illiquid securities” 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.

Operational Risk. Your ability to transact with the Fund or the valuation of your investment 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 (including those due to cybersecurity incidents), 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 eliminate or mitigate the occurrence of such failures. The Fund and its shareholders could be negatively impacted as a result.

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.

Cybersecurity Risk. Like other funds and business enterprises, the Fund, the Fund’s investment advisers 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 stockholder information) or proprietary information, cause the Fund, the manager, the subadviser 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 of common stock, receiving distributions or receiving timely information regarding the Fund or their investment in the Fund. The Fund and the Fund’s investment advisers 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 and/or the Fund’s investment advisers. 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

Western Asset Investment Grade Income Fund Inc.

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.

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 prospectus, dated March 15, 1973, 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.

Western Asset Investment Grade Income Fund Inc.

Dividend reinvestment plan (unaudited)

The Fund offers to all shareholders a Dividend Reinvestment Plan (“Plan”). For participants in the Plan, cash distributions (e.g., dividends and capital gains) of registered shareholders (those who own shares in their own name on the Fund’s records) are automatically invested in shares of the Fund. Interested shareholders may obtain more information or sign up for the Plan by contacting the agent. Shareholders who own shares in a brokerage, bank, or other financial institution account must contact the Company where their account is held in order to participate in the Plan.

If you elect to participate in the Plan you will automatically receive your dividend or net capital gains distribution in newly issued shares of the Fund if the market price of a share on the date of the distribution is at or above the net asset value (“NAV”) of a Fund share. The number of shares to be issued to you will be determined by dividing the amount of the cash distribution to which you are entitled (net of any applicable withholding taxes) by the greater of the NAV per share on such date or 95% of the market price of a share on such date. If the market price of a share on such distribution date is below the NAV the Agent will, as agent for the participants, buy shares of the Fund’s stock through a broker on the open market or in a negotiated transaction (subject to price and other terms to which the agent may agree). The price per share of shares purchased for each participant’s account with respect to a particular dividend or other distribution will be the average price (including brokerage commissions, transfer taxes and any other costs of purchase) of all shares purchased with respect to that dividend or other distribution. All shares of common stock acquired on your behalf through the Plan will be automatically credited to an account maintained on the books of the Agent. Full and fractional shares will be voted by the Agent in accordance with your instructions.

Additional information regarding the plan

The Fund will pay all costs applicable to the Plan, with the exceptions noted below. Brokerage commissions, transfer taxes and any other costs of purchase or sale by the Agent under the Plan will be charged to participants. The commission participants pay for selling shares under the Plan is calculated as $2.50 plus $0.15 per share. Beneficial shareholders should contact the company holding their account for further information concerning fees that may apply to selling shares under the Plan. In the event the Fund determines to no longer pay the costs applicable to the Plan, the Agent will terminate the Plan and may, but is not obligated to, offer a new plan under which it would impose a direct service charge on participants.

All shares acquired through the Plan receive voting rights and are eligible for any stock split, stock dividend, or other rights accruing to shareholders that the Board of Directors may declare. Distributions to Plan participants will be in the form of stock, unless the Agent is notified in writing 10 days prior to the record date fixed by the Board of Directors for the distribution that you wish to receive a cash payment. Beneficial shareholders should contact the company holding their account for further information regarding deadlines that might apply.

You may terminate participation in the Plan at any time by giving written notice to the Agent. Such termination will be effective prior to the record date next succeeding the receipt of such instructions or by a later date of termination specified in such instructions.

Western Asset Investment Grade Income Fund Inc.

Upon termination of the Plan, a participant may request a certificate for the full shares credited to his or her account or may request the sale of all or part of such shares. If the participant instructs the Agent to sell the shares credited to the participant’s account, the Agent may accumulate such shares and those of any other terminating participants for purposes of such sale. Brokerage charges, transfer taxes, and any other costs of sale will be allocated pro rata among the selling participants. Any such sale may be made on any securities exchange where such shares are traded, in the over-the-counter market or in negotiated transactions, and may be subject to such terms of price, delivery, etc., as the Agent may agree to. Fractional shares credited to a terminating account will be paid for in cash at the current market price at the time of termination.

Dividends and other distributions invested in additional shares under the Plan are subject to income tax just as if they had been received in cash. After year end, dividends paid on the accumulated shares will be included in the Form 1099-DIV information return to the Internal Revenue Service and only one Form 1099-DIV will be sent to each participant each year.

Registered shareholders can make inquiries regarding the Plan, as well as sign up or terminate their participation in the Plan by contacting Computershare Inc., P.O. Box 43006 Providence, RI 02940-3078, telephone number 1-888-888-0151. Beneficial Shareholders can make inquiries regarding the Plan as well as sign up or terminate their participation in the Plan by contacting the company where their account is held.

There were no other non-audit services rendered by the Auditor to Franklin Templeton Fund Adviser, LLC (“FTFA”), and any entity controlling, controlled by or under common control with FTFA that provided ongoing services to Western Asset Investment Grade Income Fund Inc. requiring pre-approval by the Audit Committee in the Reporting Period.

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

(1) The Charter for the Audit Committee (the “Committee”) of the Board of each registered investment company (the “Fund”) advised by FTFA or one of their affiliates (each, an “Adviser”) requires that the Committee shall approve (a) all audit and permissible non-audit services to be provided to the Fund and (b) all permissible non-audit services to be provided by the Fund’s independent auditors to the Adviser and any Covered Service Providers if the engagement

relates directly to the operations and financial reporting of the Fund. The Committee may implement policies and procedures by which such services are approved other than by the full Committee.

The Committee shall not approve non-audit services that the Committee believes may impair the independence of the auditors. As of the date of the approval of this Audit Committee Charter, permissible non-audit services include any professional services (including tax services), that are not prohibited services as described below, provided to the Fund by the independent auditors, other than those provided to the Fund in connection with an audit or a review of the financial statements of the Fund. Permissible non-audit services may not include: (i) bookkeeping or other services related to the accounting records or financial statements of the Fund; (ii) financial information systems design and implementation; (iii) appraisal or valuation services, fairness opinions or contribution-in-kind reports; (iv) actuarial services; (v) internal audit outsourcing services; (vi) management functions or human resources; (vii) broker or dealer, investment adviser or investment banking services; (viii) legal services and expert services unrelated to the audit; and (ix) any other service the Public Company Accounting Oversight Board determines, by regulation, is impermissible.

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

(2) None of the services described in paragraphs (b) through (d) of this Item were performed in reliance on paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

(f) Not applicable.

(h) Yes. Western Asset Investment Grade Income Fund Inc.’s Audit Committee has considered whether the provision of non-audit services that were rendered to Service Affiliates, which were not pre-approved (not requiring pre-approval), is compatible with maintaining the Accountant’s independence. All services provided by the Auditor to the Western Asset Investment Grade Income Fund Inc. or to Service Affiliates, which were required to be pre-approved, were pre-approved as required.

(i) Not applicable.

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

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:

Issuer name;

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

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

A brief identification of the matter voted on;

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

Whether a vote was cast on the matter;

A record of how the vote was cast;

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

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:

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

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

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

Voting Guidelines

Western Asset’s substantive voting decisions 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.

Board Approved Proposals

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

Matters relating to the Board of Directors

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

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

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

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

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

Matters relating to Executive Compensation

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

•

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

•

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

•

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

•

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

	3.	Matters relating to Capitalization

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

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

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

	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.

Matters relating to Anti-Takeover Measures

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

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

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

Other Business Matters

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

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

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

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:

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

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

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

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.

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

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

IV.

Voting Shares of Foreign Issuers

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

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

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

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

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

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.

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

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.

	•	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.

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.

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.
