Portfolio Composition - continued
(a) For all securities other than those specifically described below, ratings are assigned to underlying securities utilizing ratings from Moody’s, Fitch, and Standard & Poor’s rating agencies and applying the following hierarchy: If all three agencies provide a rating, the middle rating (after dropping the highest and lowest ratings) is assigned; if two of the three agencies rate a security, the lower of the two is assigned. If none of the 3 rating agencies above assign a rating, but the security is rated by DBRS Morningstar, then the DBRS Morningstar rating is assigned. If none of the 4 rating agencies listed above rate the security, but the security is rated by the Kroll Bond Rating Agency (KBRA), then the KBRA rating is assigned. Ratings are shown in the S&P and Fitch scale (e.g., AAA). Securities rated BBB or higher are considered investment grade. All ratings are subject to change. Not Rated includes fixed income securities and fixed income derivatives that have not been rated by any rating agency. Non-Fixed Income includes equity securities (including convertible bonds and equity derivatives), ETFs and Options on ETFs, and/or commodity-linked derivatives. The fund may or may not have held all of these instruments on this date. The fund is not rated by these agencies.
(b) Cash & Cash Equivalents (Less Liabilities) includes any cash, investments in money market funds, short-term securities, and other assets less liabilities. Liabilities include the value of the aggregate liquidation preference of the remarketable variable rate munifund term preferred shares (RVMTP shares) issued by the fund. Cash & Cash Equivalents (Less Liabilities) is negative due to the aggregate liquidation value of RVMTP shares. Please see the Statement of Assets and Liabilities for additional information related to the fund’s cash position and other assets and liabilities. Please see Note 8 in the Notes to Financial Statements for more information on the RVMTP shares issued by the fund.
(d) Duration is a measure of how much a bond’s price is likely to fluctuate with general changes in interest rates, e.g., if rates rise 1.00%, a bond with a 5-year duration is likely to lose about 5.00% of its value due to the interest rate move. The Average Duration calculation reflects the impact of the equivalent exposure of derivative positions, if any. This calculation is based on net assets applicable to common shares as of May 31, 2024.
(i) For purposes of this presentation, the components include the value of securities, and reflect the impact of the equivalent exposure of derivative positions, if any. These amounts may be negative from time to time. Equivalent exposure is a calculated amount that translates the derivative position into a reasonable approximation of the amount of the underlying asset that the portfolio would have to hold at a given point in time to have the same price sensitivity that results from the portfolio’s ownership of the derivative contract. When dealing with derivatives, equivalent exposure is a more representative measure of the potential impact of a position on portfolio performance than value. The bond component will include any accrued interest amounts.
(m) In determining each instrument’s effective maturity for purposes of calculating the fund’s dollar-weighted average effective maturity, MFS uses the instrument’s stated maturity or, if applicable, an earlier date on which MFS believes it is probable that a maturity-shortening feature (such as a put, pre-refunding or prepayment) will cause the instrument to be repaid. Such an earlier date can be substantially shorter than the instrument’s stated maturity. This calculation is based on gross assets, which consists of net assets applicable to common shares plus the value of preferred shares, as of May 31, 2024.
(o) Less than 0.1%.
Percentages are based on net assets applicable to common shares as of May 31, 2024.
The portfolio is actively managed and current holdings may be different.

Michael Dawson Portfolio Manager 2007 Investment Officer of MFS; employed in the investment management area of MFS since 1998.

Other Notes
The fund’s shares may trade at a discount or premium to net asset value. When fund shares trade at a premium, buyers pay more than the net asset value of the underlying fund shares, and shares purchased at a premium would receive less than the amount paid for them in the event of the fund’s concurrent liquidation.
The fund’s monthly distributions may include a return of capital to shareholders to the extent that distributions are in excess of the fund’s net investment income and net capital gains, determined in accordance with federal income tax regulations. Distributions that are treated for federal income tax purposes as a return of capital will reduce each shareholder’s basis in his or her shares and, to the extent the return of capital exceeds such basis, will be treated as gain to the shareholder from a sale of shares. Returns of shareholder capital may have the effect of reducing the fund’s assets and increasing the fund’s expense ratio.
In accordance with Section 23(c) of the Investment Company Act of 1940, the fund hereby gives notice that it may from time to time repurchase shares of the fund in the open market at the option of the Board of Trustees and on such terms as the Trustees shall determine.

(unaudited) 
(1) Business and Organization
MFS Investment Grade Municipal Trust (the fund) is organized as a Massachusetts business trust and is registered under the Investment Company Act of 1940, as amended, as a diversified closed-end management investment company.
The fund is an investment company and accordingly follows the investment company accounting and reporting guidance of the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946 Financial Services - Investment Companies.
(2) Significant Accounting Policies
General — The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates. In the preparation of these financial statements, management has evaluated subsequent events occurring after the date of the fund’s Statement of Assets and Liabilities through the date that the financial statements were issued. The fund invests primarily in municipal instruments, which generally trade in the over-the-counter market. The value of municipal instruments can be affected by changes in their actual or perceived credit quality. The credit quality of, and the ability to pay principal and interest when due by, an issuer of a municipal instrument depends on the credit quality of the entity supporting the municipal instrument, how essential any services supported by the municipal instrument are, the sufficiency of any revenues or taxes that support the municipal instrument, and/or the willingness or ability of the appropriate government entity to approve any appropriations necessary to support the municipal instrument. Municipal instruments may be supported by insurance which typically guarantees the timely payment of all principal and interest due on the underlying municipal instrument. The value of a municipal instrument can be volatile and significantly affected by adverse tax changes or court rulings, legislative or political changes, changes in specific or general market and economic conditions in the region where the instrument is issued, and the financial condition of municipal issuers and of municipal instrument insurers of which there are a limited number. Also, because many municipal instruments are issued to finance similar projects, conditions in certain industries can significantly affect the fund and the overall municipal market. If the Internal Revenue Service determines an issuer of a municipal instrument has not complied with the applicable tax requirements, interest from the security could become taxable, the security could decline in value, and certain distributions made by the fund could be taxable to shareholders. The fund invests in high-yield securities rated below investment grade. Investments in below investment grade quality securities can involve a substantially greater risk of default or can already be in default, and their values can decline significantly. Below investment grade quality securities tend to be more sensitive to adverse news about the issuer, or the market or economy in general, than higher quality debt instruments.
Balance Sheet Offsetting — The fund's accounting policy with respect to balance sheet offsetting is that, absent an event of default by the counterparty or a termination of the agreement, the International Swaps and Derivatives Association (ISDA) Master
37
Notes to Financial Statements (unaudited) - continued 
Agreement, or similar agreement, does 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 fund's right to setoff may be restricted or prohibited by the bankruptcy or insolvency laws of the particular jurisdiction to which a specific master netting agreement counterparty is subject. Balance sheet offsetting disclosures, to the extent applicable to the fund, have been included in the fund’s Significant Accounting Policies note under the captions for each of the fund’s in-scope financial instruments and transactions.
Investment Valuations — Subject to its oversight, the fund's Board of Trustees has delegated primary responsibility for determining or causing to be determined the value of the fund’s investments to MFS as the fund's adviser, pursuant to the fund’s valuation policy and procedures which have been adopted by the adviser and approved by the Board. In accordance with Rule 2a-5 under the Investment Company Act of 1940, the Board of Trustees designated the adviser as the “valuation designee” of the fund. If the adviser, as valuation designee, determines that reliable market quotations are not readily available for an investment, the investment is valued at fair value as determined in good faith by the adviser in accordance with the adviser’s fair valuation policy and procedures.
Under the fund's valuation policy and procedures, equity securities, including restricted equity securities, are generally valued at the last sale or official closing price on their primary market or exchange as provided by a third-party pricing service. Equity securities, for which there were no sales reported that day, are generally valued at the last quoted daily bid quotation on their primary market or exchange as provided by a third-party pricing service. Debt instruments and floating rate loans, including restricted debt instruments, are generally valued at an evaluated or composite bid as provided by a third-party pricing service. Short-term instruments with a maturity at issuance of 60 days or less may be valued at amortized cost, which approximates market value.
Open-end investment companies are generally valued at net asset value per share.
Under the fund’s valuation policy and procedures, market quotations are not considered to be readily available for debt instruments, floating rate loans, and many types of derivatives. These investments are generally valued at fair value based on information from third-party pricing services or otherwise determined by the adviser in accordance with the adviser’s fair valuation policy and procedures. Securities and other assets generally valued on the basis of information from a third-party pricing service may also be valued at a broker/dealer bid quotation. In determining values, third-party pricing services can utilize both transaction data and market information such as yield, quality, coupon rate, maturity, type of issue, trading characteristics, spreads and other market data. An investment may also be valued at fair value if the adviser determines that the investment’s value has been materially affected by events occurring after the close of the exchange or market on which the investment is principally traded (such as foreign exchange or market) and prior to the determination of the fund’s net asset value, or after the halt of trading of a specific security where trading does not resume prior to the close of the exchange or market on which the security is principally traded. The adviser generally relies on third-party pricing services or other information (such as the correlation with price movements of similar securities in the same or other markets; the type, cost and investment characteristics of the security; the business and financial condition of the issuer; and trading and other market data) to assist in determining whether to fair value and at what value to fair value an investment. The value of an investment for purposes of calculating the fund’s net asset value can differ depending
38
Notes to Financial Statements (unaudited) - continued 
on the source and method used to determine value. When fair valuation is used, the value of an investment used to determine the fund’s net asset value may differ from quoted or published prices for the same investment. There can be no assurance that the fund could obtain the fair value assigned to an investment if it were to sell the investment at the same time at which the fund determines its net asset value per share.
Various inputs are used in determining the value of the fund's assets or liabilities. These inputs are categorized into three broad levels. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, an investment's level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The fund's assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the investment. Level 1 includes unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 includes other significant observable market-based inputs (including quoted prices for similar securities, interest rates, prepayment speed, and credit risk). Level 3 includes significant unobservable inputs, which may include the adviser's own assumptions in determining the fair value of investments. The following is a summary of the levels used as of May 31, 2024 in valuing the fund's assets and liabilities:
Financial Instruments Level 1 Level 2 Level 3 Total
Equity Securities:        
Netherlands $— $— $11,461 $11,461
Municipal Bonds — 111,244,608 — 111,244,608
U.S. Corporate Bonds — 59,595 — 59,595
Mutual Funds 621,691 — — 621,691
Total $621,691 $111,304,203 $11,461 $111,937,355
For further information regarding security characteristics, see the Portfolio of Investments. 
The following is a reconciliation of level 3 assets for which significant unobservable inputs were used to determine fair value. The table presents the activity of level 3 securities held at the beginning and the end of the period.

At May 31, 2024, the fund held one level 3 security.
Statement of Cash Flows — Information on financial transactions which have been settled through the receipt or disbursement of cash or restricted cash is presented in the Statement of Cash Flows. Cash as presented in the fund's Statement of Assets and Liabilities includes cash on hand at the fund's custodian bank and does not include any short-term investments. Restricted cash is presented in the fund's Statement of Assets and Liabilities as restricted cash for uncleared derivatives and/or deposits with brokers for cleared derivatives and represents cash that has been segregated or delivered to cover the fund's collateral or margin obligations under derivative contracts.
39
Notes to Financial Statements (unaudited) - continued 
Indemnifications — Under the fund's organizational documents, its officers and Trustees may be indemnified against certain liabilities and expenses arising out of the performance of their duties to the fund. Additionally, in the normal course of business, the fund enters into agreements with service providers that may contain indemnification clauses. The fund's maximum exposure under these agreements is unknown as this would involve future claims that may be made against the fund that have not yet occurred.
Investment Transactions and Income —  Interest income is recorded on the accrual basis. All premium and discount is amortized or accreted for financial statement purposes in accordance with U.S. generally accepted accounting principles. Dividend and interest payments received in additional securities are recorded on the ex-dividend or ex-interest date in an amount equal to the value of the security on such date. Debt obligations may be placed on non-accrual status or set to accrue at a rate of interest less than the contractual coupon when the collection of all or a portion of interest has become doubtful. Interest income for those debt obligations may be further reduced by the write-off of the related interest receivables when deemed uncollectible.
The fund may receive proceeds from litigation settlements. Any proceeds received from litigation involving portfolio holdings are reflected in the Statement of Operations in realized gain/loss if the security has been disposed of by the fund or in unrealized gain/loss if the security is still held by the fund. Any other proceeds from litigation not related to portfolio holdings are reflected as other income in the Statement of Operations.
Investment transactions are recorded on the trade date.  In determining the net gain or loss on securities sold, the cost of securities is determined on the identified cost basis.
The fund may purchase or sell securities on a when-issued or delayed delivery basis.  In these extended settlement transactions, the receipt or delivery of the securities by the fund and related payments occur at a future date, usually beyond the customary settlement period. The price of such security and the date that the security will be settled are generally fixed at the time the transaction is negotiated. The value of the security varies with market fluctuations and for debt securities no interest accrues to the fund until settlement takes place. When the fund sells securities on a when-issued or delayed delivery basis, the fund typically owns or has the right to acquire securities equivalent in kind and amount to the securities sold. Purchase and sale commitments for when-issued or delayed delivery securities are held at carrying amount, which approximates fair value and are categorized as level 2 within the fair value hierarchy, and included in When-issued investments purchased and When-issued investments sold in the Statement of Assets and Liabilities, as applicable. Losses may arise due to changes in the value of the underlying securities prior to settlement date or if the counterparty does not perform under the contract’s terms, or if the issuer does not issue the securities due to political, economic or other factors.
Legal fees and other related expenses incurred to preserve and protect the value of a security owned are added to the cost of the security; other legal fees are expensed. Capital infusions made directly to the security issuer, which are generally non-recurring, incurred to protect or enhance the value of high-yield debt securities, are reported as additions to the cost basis of the security. Costs that are incurred to negotiate the
40
Notes to Financial Statements (unaudited) - continued 
terms or conditions of capital infusions or that are expected to result in a plan of reorganization are reported as realized losses. Ongoing costs incurred to protect or enhance an investment, or costs incurred to pursue other claims or legal actions, are expensed.
Tax Matters and Distributions — The fund intends to qualify as a regulated investment company, as defined under Subchapter M of the Internal Revenue Code, and to distribute all of its taxable and tax-exempt income, including realized capital gains. As a result, no provision for federal income tax is required. The fund’s federal tax returns, when filed, will remain subject to examination by the Internal Revenue Service for a three year period. Management has analyzed the fund’s tax positions taken on federal and state tax returns for all open tax years and does not believe that there are any uncertain tax positions that require recognition of a tax liability.
Distributions to shareholders are recorded on the ex-dividend date. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from U.S. generally accepted accounting principles. Certain capital accounts in the financial statements are periodically adjusted for permanent differences in order to reflect their tax character. These adjustments have no impact on net assets or net asset value per share. Temporary differences which arise from recognizing certain items of income, expense, gain or loss in different periods for financial statement and tax purposes will reverse at some time in the future.
Book/tax differences primarily relate to defaulted bonds, amortization of premium and accretion of discount of debt securities, accounting for secured borrowings, and non-deductible expenses that result from the treatment of preferred shares as equity for tax purposes.
The tax character of distributions made during the current period will be determined at fiscal year end. The tax character of distributions declared to shareholders for the last fiscal year is as follows:
  Year ended
11/30/23
Ordinary income (including any short-term capital gains) $238,319
Tax-exempt income 4,340,592
Total distributions $4,578,911

Notes to Financial Statements (unaudited) - continued 
The federal tax cost and the tax basis components of distributable earnings were as follows:
As of 5/31/24  
Cost of investments $115,754,212
Gross appreciation 1,968,995
Gross depreciation (5,785,852)
Net unrealized appreciation (depreciation) $(3,816,857)

Capital loss carryforwards (6,379,082)
Other temporary differences (172,814)
Net unrealized appreciation (depreciation) (3,855,677)
The aggregate cost above includes prior fiscal year end tax adjustments, if applicable.
As of November 30, 2023, the fund had capital loss carryforwards available to offset future realized gains. These net capital losses may be carried forward indefinitely and their character is retained as short-term and/or long-term losses. Such losses are characterized as follows:
Short-Term $(1,731,576)
Long-Term (4,647,506)
Total $(6,379,082)
(3) Transactions with Affiliates
Investment Adviser — The fund has an investment advisory agreement with MFS to provide overall investment management and related administrative services and facilities to the fund. The management fee is computed daily and paid monthly at an annual rate of 0.65% of the fund’s average daily net assets (including the value of preferred shares). The investment adviser has agreed in writing to reduce its management fee to 0.63% of the fund’s average daily net assets (including the value of preferred shares). This written agreement will continue until modified by the fund’s Board of Trustees, but such agreement will continue at least until November 30, 2024. For the six months ended May 31, 2024, this management fee reduction amounted to $11,449, which is included in the reduction of total expenses in the Statement of Operations. The management fee incurred for the six months ended May 31, 2024 was equivalent to an annual effective rate of 0.63% of the fund's average daily net assets (including the value of preferred shares).
The investment adviser has agreed in writing to pay a portion of the fund’s total annual operating expenses, excluding interest expense on RVMTP shares, taxes, extraordinary expenses, brokerage and transaction costs, certain tax reclaim recovery expenses (including contingency fees and closing agreement expenses), other interest expense, and investment-related expenses, such that total fund operating expenses do not exceed 0.72% annually of the fund’s average daily net assets (including the value of preferred shares). This written agreement will continue until modified by the fund’s Board of Trustees, but such agreement will continue at least until November 30, 2024. For the six months ended May 31, 2024, this reduction amounted to $80,304, which is included in the reduction of total expenses in the Statement of Operations.
42
Notes to Financial Statements (unaudited) - continued 
Transfer Agent — The fund engages Computershare Trust Company, N.A. (“Computershare”) as the sole transfer agent for the fund's common shares. MFS Service Center, Inc. (MFSC) monitors and supervises the activities of Computershare for an agreed upon fee approved by the Board of Trustees. For the six months ended May 31, 2024, fees paid to MFSC amounted to $1,623.
Administrator – MFS provides certain financial, legal, shareholder communications, compliance, and other administrative services to the fund.  Under an administrative services agreement, the fund reimburses MFS the costs incurred to provide these services. The fund is charged an annual fixed amount of $17,500 plus a fee based on average daily net assets (including the value of preferred shares). The administrative services fee is computed daily and paid monthly. The administrative services fee incurred for the six months ended May 31, 2024 was equivalent to an annual effective rate of 0.0233% of the fund’s average daily net assets (including the value of preferred shares).
Trustees’ and Officers’ Compensation — The fund pays compensation to independent Trustees in the form of a retainer, attendance fees, and additional compensation to Board and Committee chairpersons. Independent Trustees’ compensation is accrued daily and paid subsequent to each Trustee Board meeting. The fund does not pay compensation directly to Trustees or officers of the fund who are also officers of the investment adviser, all of whom receive remuneration from MFS for their services to the fund.  Certain officers and Trustees of the fund are officers or directors of MFS and MFSC.
Other — The fund invests in the MFS Institutional Money Market Portfolio which is managed by MFS and seeks current income consistent with preservation of capital and liquidity. This money market fund does not pay a management fee to MFS but does incur investment and operating costs.
During the six months ended May 31, 2024, pursuant to a policy adopted by the Board of Trustees and designed to comply with Rule 17a-7 under the Investment Company Act of 1940 (the “Act”) and relevant guidance, the fund engaged in purchase and sale transactions with funds and accounts for which MFS serves as investment adviser or sub-adviser (“cross-trades”) which amounted to $20,767 and $145,228, respectively. The sales transactions resulted in net realized gains (losses) of $(28,558).
(4) Portfolio Securities
For the six months ended May 31, 2024, purchases and sales of investments, other than short-term obligations, aggregated $9,056,041 and $10,270,281, respectively.
(5) Shares of Beneficial Interest
The fund’s Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional shares of beneficial interest. The fund reserves the right to repurchase shares of beneficial interest of the fund subject to Trustee approval.
On October 6, 2023, the fund commenced a cash tender offer for up to 10% of the fund’s outstanding common shares at a price per share equal to 98% of the fund’s net asset value per share calculated at the close of regular trading on the New York Stock Exchange on the expiration date of the offer. This tender offer expired on November 6, 2023, at which time the offer was oversubscribed. The fund purchased the maximum number of shares offered in the tender offer (911,025 common shares representing 10% of the fund’s then outstanding common shares). The purchase price of the
43
Notes to Financial Statements (unaudited) - continued 
properly tendered shares was equal to $7.634 per share for an aggregate purchase price of $6,954,765. As a result of this tender offer, payment was made by the fund on November 15, 2023. The Trustees authorized the tender offer as part of an agreement with a large shareholder of the fund. Pursuant to the agreement, the Trustees also agreed to propose a liquidity event at the fund’s 2025 annual meeting of shareholders, unless the average trading discount of the shares is equal to or less than 7.5% for the entirety of any consecutive 30 calendar day period between November 6, 2023 and July 15, 2025.
During the six months ended May 31, 2024 and the year ended November 30, 2023, the fund did not repurchase any additional shares other than through this tender offer and there were no other transactions in fund shares.
(6) Line of Credit
The fund and certain other funds managed by MFS participate in a $1.45 billion unsecured committed line of credit of which $1.2 billion is reserved for use by the fund and certain other MFS U.S. funds. The line of credit is provided by a syndicate of banks under a credit agreement. Borrowings may be made for temporary financing needs. Interest is charged to each fund, based on its borrowings, generally at a rate equal to the highest of 1) Daily Simple SOFR (Secured Overnight Financing Rate) plus 0.10%, 2) the Federal Funds Effective Rate, or 3) the Overnight Bank Funding Rate, each plus an agreed upon spread. A commitment fee, based on the average daily unused portion of the committed line of credit, is allocated among the participating funds. The line of credit expires on March 13, 2025 unless extended or renewed. In addition, the fund and other funds managed by MFS have established unsecured uncommitted borrowing arrangements with certain banks for temporary financing needs. Interest is charged to each fund, based on its borrowings, at rates equal to customary reference rates plus an agreed upon spread. For the six months ended May 31, 2024, the fund’s commitment fee and interest expense were $180 and $0, respectively, and are included in “Interest expense and fees and amortization of RVMTP shares debt issuance costs” in the Statement of Operations.
(7) Investments in Affiliated Issuers

(8) Preferred Shares
The fund has 438 shares issued and outstanding of RVMTP shares. The outstanding RVMTP shares are redeemable at the option of the fund in whole or in part at the liquidation preference of $100,000 per share, plus accumulated and unpaid dividends, but generally solely for the purpose of decreasing the leverage of the fund. The RVMTP shares have a stated maturity date of 2051 but are subject to a mandatory early term redemption date at each 42 month anniversary from the original date of issue and subsequent extensions of the RVMTP shares, unless the holder(s) of the RVMTP shares agrees to retain the RVMTP shares. Otherwise, the RVMTP shares are subject to mandatory tender for remarketing to another purchaser. In the event the remarketing is unsuccessful, the RVMTP shares would be subject to redemption at the liquidation preference of $100,000 per share, plus accumulated and unpaid dividends. There is no assurance that the term of the RVMTP shares will be extended or that the RVMTP shares will be replaced with any other preferred shares or other form of leverage upon the redemption of the RVMTP shares. Dividends on the RVMTP shares are cumulative and reset weekly to a fixed spread against the Securities Industry and Financial Markets Association (SIFMA) Municipal Swap Index. During the six months ended May 31, 2024, the dividend rates on the RVMTP shares ranged from 2.90% to 5.55%. For the six months ended May 31, 2024, the average dividend rate was 4.50%.
In the fund’s Statement of Assets and Liabilities, the RVMTP shares aggregate liquidation preference is shown as a liability since they have a stated mandatory redemption date. Dividends paid on the RVMTP shares are treated as interest expense and recorded as incurred. For the six months ended May 31, 2024, interest expense related to the dividends paid on RVMTP shares amounted to $1,008,518 and is included in “Interest expense and fees and amortization of RVMTP shares debt issuance costs” in the Statement of Operations. Costs directly related to the issuance of the RVMTP shares are considered debt issuance costs. Debt issuance costs are presented as a direct deduction from the carrying amount of the related debt liability and are amortized into interest expense over the life of the RVMTP shares. The period-end carrying value for the RVMTP shares in the fund’s Statement of Assets and Liabilities is its liquidation value less any unamortized debt issuance costs, which approximates its fair value. Its fair value would be considered level 2 under the fair value hierarchy.
Under the terms of a purchase agreement between the fund and the investor in the RVMTP shares, the fund is subject to various investment restrictions. These investment-related requirements are in various respects more restrictive than those to which the fund is otherwise subject in accordance with its investment objectives and policies. In addition, the fund is subject to certain restrictions on its investments imposed by guidelines of the rating agency that rates the RVMTP shares, which guidelines may be changed by the applicable rating agency, in its sole discretion, from time to time. These guidelines may impose asset coverage or portfolio composition requirements that are more stringent than those imposed on the fund by the Investment Company Act of 1940 (the “1940 Act”).
The fund is required to maintain certain asset coverage with respect to the RVMTP shares as defined in the fund’s governing documents and the 1940 Act. One of a number of asset coverage-related requirements is that the fund is not permitted to declare or pay common share dividends unless immediately thereafter the fund has a minimum asset coverage ratio of at least 200% with respect to the RVMTP shares after

deducting the amount of such common share dividends. The fund may be subject to more stringent asset coverage levels which exceed the requirements under the 1940 Act and may change from time to time as agreed to by the fund and the holders of the RVMTP shares.
The 1940 Act requires that the preferred shareholders of the fund, voting as a separate class, have the right to elect at least two trustees at all times, and elect a majority of the trustees at any time when dividends on the preferred shares are unpaid for two full years. Unless otherwise required by law or under the terms of the preferred shares, each preferred share is entitled to one vote and preferred shareholders will vote together with common shareholders as a single class.
Leverage involves risks and special considerations for the fund’s common shareholders. To the extent that investments are purchased by the fund with proceeds from the issuance of preferred shares, the fund’s net asset value will increase or decrease at a greater rate than a comparable unleveraged fund. Changes in the value of the fund’s portfolio will be borne entirely by the common shareholders. It is possible that the fund will be required to sell assets at a time when it may be disadvantageous to do so in order to redeem preferred shares to comply with asset coverage or other restrictions including those imposed by the 1940 Act and the rating agency that rates the preferred shares. There is no assurance that the fund’s leveraging strategy will be successful.
(9) Subsequent Event
On June 17, 2024, the fund filed a notice with the Securities and Exchange Commission indicating that during the period July 18, 2024 to December 31, 2024 the fund intends to redeem approximately 15% of its outstanding RVMTP Shares, but may redeem less.

Report of Independent Registered Public Accounting Firm
To the Shareholders and the Board of Trustees of MFS Investment Grade Municipal Trust
Results of Review of Interim Financial Statements
We have reviewed the accompanying statement of assets and liabilities of MFS Investment Grade Municipal Trust (the “Fund”), including the portfolio of investments, as of May 31, 2024, and the related statements of operations, changes in net assets, cash flows and financial highlights for the six-month period then ended and the related notes (collectively referred to as the “interim financial statements”). Based on our review, we are not aware of any material modifications that should be made to the interim financial statements for them to be in conformity with U.S. generally accepted accounting principles.
We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the statement of changes in net assets for the year ended November 30, 2023 and the financial highlights for each of the five years in the period then ended; and in our report dated January 16, 2024, we expressed an unqualified opinion on those financial statements.
Basis for Review Results
These financial statements are the responsibility of the Fund's management. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the SEC and the PCAOB. We conducted our review in accordance with the standards of the PCAOB. A review of interim financial statements consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the PCAOB, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

The aggregate number of shares available for purchase for the October 1, 2023 plan year is 911,025.
