Manning] Dear Shareholders: The past year has been a great example of why investors should keep their eyes on the long term. In 2006 the Dow Jones Industrial Average returned 19% and was fairly stable. This year we have seen a greater level of volatility than has been experienced in recent years. The Dow hit several new highs but also experienced swift drops as a global credit crisis swept through markets, spurred by defaults on U.S. subprime loans and a liquidity crunch. Still, even with this volatility, the Dow ended the first three quarters of 2007 with a return near 13%. U.S. Treasury bonds gained ground, especially in the third quarter as investors sought less risky asset classes. The spreads of many lower quality debt investments widened. In 2007 the U.S. dollar fell against the euro, oil prices have hit their highest levels yet, and gold has spiked to its steepest price in 28 years. Around the globe, stocks sold off as risk aversion mounted. As we have said before, markets can be volatile, and investors should make sure they have an investment plan that can carry them through the peaks and troughs. If you are focused on a long-term investment strategy, the short-term ups and downs of the markets should not necessarily dictate portfolio action on your part. In our view, investors who remain committed to a long-term plan are more likely to achieve their financial goals. In any market environment, we believe individual investors are best served by following a three- pronged investment strategy of allocating their holdings across the major asset classes, diversifying within each class, and regularly rebalancing their portfolios to maintain their desired allocations. Of course, these strategies cannot guarantee a profit or protect against a loss. Investing and planning for the long term require diligence and patience, two traits that in our experience are essential to capitalizing on the many opportunities the financial markets can offer -- through both up and down economic cycles. Respectfully, /s/ Robert J. Manning Robert J.

(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. (i) For purposes of this presentation, the bond component includes both accrued interest amounts and the equivalent exposure from any derivative holdings, if applicable. (m) The average maturity shown is calculated using the final stated maturity on the portfolio's holdings without taking into account any holdings which have been pre-refunded or pre-paid to an earlier date or which have a mandatory put date prior to the stated ma turity. The average life shown takes into account these earlier dates. (r) Each security is assigned a rating from Moody's Investors Service. If not rated by Moody's, the rating will be that assigned by Standard & Poor's. Likewise, if not assigned a rating by Standard & Poor's, it will be based on the rating assigned by Fitch, Inc. For those portfolios that hold a security which is not rated by any of the three agencies, the security is considered Not Rated. Holdings in U.S. Treasuries and government agency mortgage-backed securities, if any, are included in the "AAA"-rating category. Percentages are based on the total market value of investments as of 09/30/07. From time to time "Cash & Other Net Assets" may be negative due to timing of cash receipts and/or equivalent exposure from any derivative holdings. Percentages are based on net assets as of 09/30/07, unless otherwise noted. The portfolio is actively managed and current holdings may be different.

EXPENSE TABLES FUND EXPENSES BORNE BY THE SHAREHOLDERS DURING THE PERIOD, APRIL 1, 2007, THROUGH SEPTEMBER 30, 2007 As a shareholder of the funds, you incur two types of costs: (1) transaction costs, including sales charges (loads) on certain purchase or redemption payments and (2) ongoing costs, including management fees; distribution and service (12b-1) fees; and other fund expenses. These examples are intended to help you understand your ongoing costs (in dollars) of investing in the funds and to compare these costs with the ongoing costs of investing in other mutual funds. These examples are based on an investment of $1,000 invested at the beginning of the period and held for the entire period April 1, 2007 through September 30, 2007. ACTUAL EXPENSES The first line for each share class in the following tables provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The second line for each share class in the following tables provides information about hypothetical account values and hypothetical expenses based on each fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in each fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads). Therefore, the second line for each share class in the tables is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

SEE NOTES TO FINANCIAL STATEMENTS NOTES TO FINANCIAL STATEMENTS (unaudited) (1) BUSINESS AND ORGANIZATION MFS Alabama Municipal Bond Fund (Alabama Fund), MFS Arkansas Municipal Bond Fund (Arkansas Fund), MFS California Municipal Bond Fund (California Fund), MFS Florida Municipal Bond Fund (Florida Fund), MFS Georgia Municipal Bond Fund (Georgia Fund), MFS Maryland Municipal Bond Fund (Maryland Fund), and MFS Massachusetts Municipal Bond Fund (Massachusetts Fund) are each a series of MFS Municipal Series Trust which is organized as a Massachusetts business trust and is registered under the Investment Company Act of 1940, as amended, as an open-end management investment company. (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 revenues and expenses during the reporting period. Actual results could differ from those estimates. Because each fund invests primarily in the securities of a single state and its political subdivisions, each fund is vulnerable to the effects of changes in the legal and economic environment of the particular state. Municipal securities backed by current or anticipated revenues from a specific project or specific assets can be negatively affected by the discontinuance of the taxation supporting the projects or assets or the inability to collect revenues for the project or from the assets. If the Internal Revenue Service determines an issuer of a municipal security has not complied with applicable tax requirements, the security could decline in value, interest from the security could become taxable and each fund may be required to issue Form 1099-DIV. INVESTMENT VALUATIONS - Debt instruments (other than short-term instruments), including restricted debt instruments, are generally valued at an evaluated or composite bid as reported by an independent 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. Swaps are generally valued at an evaluated bid as reported by an independent pricing service. Securities and other assets generally valued on the basis of information from an independent pricing service may also be valued at a broker-dealer bid quotation. Values obtained from pricing services can utilize both dealer-supplied valuations and electronic data processing techniques, which take into account factors such as institutional-size trading in similar groups of securities, yield, quality, coupon rate, maturity, type of issue, trading characteristics, and other market data. The Board of Trustees has delegated primary responsibility for determining or causing to be determined the value of each fund's investments (including any fair valuation) to the adviser pursuant to valuation policies and procedures approved by the Board. If the adviser determines that reliable market quotations are not readily available, investments are valued at fair value as determined in good faith by the adviser in accordance with such procedures under the oversight of the Board of Trustees. Under each fund's valuation policies and procedures, market quotations are not considered to be readily available for many types of debt instruments and certain types of derivatives. These investments are generally valued at fair value based on information from independent pricing services. In addition, investments may be valued at fair value if the adviser determines that an 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 each fund's net asset value, or after the halting 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 may rely on independent 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 each fund's net asset value can differ depending on the source and method used to determine value. When fair valuation is used, the value of investments used to determine each fund's net asset value may differ from quoted or published prices for the same investments. In September 2006, FASB Statement No. 157, Fair Value Measurements (the "Statement") was issued, and is effective for fiscal years beginning after November 15, 2007 and for all interim periods within those fiscal years. This Statement provides a single definition of fair value, a hierarchy for measuring fair value and expanded disclosures about fair value measurements. Management is evaluating the application of the Statement to each fund, and believes the impact will be limited to expanded disclosures resulting from the adoption of this Statement in each fund's financial statements. DERIVATIVE RISK - Each fund may invest in derivatives for hedging or non- hedging purposes. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains. When the funds use derivatives as an investment to gain market exposure, or for hedging purposes, gains and losses from derivative instruments may be substantially greater than the derivative's original cost. Derivative instruments include swap agreements. SWAP AGREEMENTS - Each fund may enter into swap agreements. A swap is an exchange of cash payments between the fund and another party. Net cash payments are exchanged at specified intervals and are recorded as a realized gain or loss in the Statements of Operations. The value of the swap is adjusted daily and the change in value, including accruals of periodic amounts of interest to be paid or received, is recorded as unrealized appreciation or depreciation in the Statements of Operations. A liquidation payment received or made upon early termination is recorded as a realized gain or loss in the Statements of Operations. Collateral, in the form of cash or securities, may be required to be held in segregated accounts with the fund's custodian in connection with these agreements. Risk of loss may exceed amounts recognized on the Statements of Assets and Liabilities. These risks include the possible lack of a liquid market, failure of the counterparty to perform under the terms of the agreements, and unfavorable market movement of the underlying instrument. All swap agreements entered into by the funds with the same counterparty are generally governed by a single master agreement, which provides for the netting of all amounts owed by the parties under the agreement upon the occurrence of an event of default, thereby reducing the credit risk to which such party is exposed. Each fund holds interest rate swap agreements which involve the periodic exchange of cash flows, such as the exchange of fixed rate interest payments for floating rate interest payments based on a notional principal amount. The interest rates may be based on a specific financial index or the exchange of two distinct floating rate payments. The funds may enter into an interest rate swap in order to manage its exposure to interest rate fluctuations. INVERSE FLOATERS - The funds invest in municipal inverse floating rate securities which are structured by the issuer (known as primary market inverse floating rate securities) or by an investment banker utilizing municipal bonds which have already been issued (known as secondary market inverse floating rate securities) to have variable rates of interest which typically move in the opposite direction of short term interest rates. A secondary market inverse floating rate security is created when an investment banker transfers a fixed rate municipal bond to a special purpose trust, and causes the trust to (a) issue floating rate certificates to third parties, in an amount equal to a fraction of the par amount of the deposited bonds (these certificates usually pay tax-exempt interest at short-term interest rates that typically reset weekly; and the certificate holders typically, on seven days notice, have the option to tender their certificates to the investment banker or another party for redemption at par plus accrued interest), and (b) issue inverse floating rate certificates (sometimes referred to as "inverse floaters"). If the holder of the inverse floater transfers the municipal bonds to an investment banker for the purpose of depositing the municipal bonds into the special purpose trust, the inverse floating rate certificates that are issued by the trust are referred to as "self-deposited inverse floaters." If the bonds held by the trust are purchased by the investment banker for deposit into the trust from someone other than the purchasers of the inverse floaters, the inverse floating rate certificates that are issued by the trust are referred to as "externally deposited inverse floaters." Such self-deposited inverse floaters held by the funds are accounted for as secured borrowings, with the municipal bonds reflected in the investments of the funds and amounts owed to the holder of the floating rate certificate under the provisions of the trust, which amounts are paid solely from the assets of the trust, reflected as liabilities of the funds in the Statements of Assets and Liabilities under the caption, "Payable to the holder of the floating rate certificate from trust assets". Interest expense and fees relate to payments made to the holder of the floating rate certificate from trust assets in connection with self-deposited inverse floater transactions. Interest expense and fees are recorded as incurred. At September 30, 2007, each fund's payable to the holder of the floating rate certificate from trust assets, the weighted average interest rate on the floating rate certificates issued by the trust, and the interest expense and fees in connection with self-deposited inverse floaters were as follows: PAYABLE TO THE HOLDER WEIGHTED AVERAGE INTEREST EXPENSE AND OF THE FLOATING RATE INTEREST RATE ON FLOATING FEES IN CONNECTION WITH CERTIFICATE FROM RATE CERTIFICATES ISSUED SELF-DEPOSITED INVERSE FUND TRUST ASSETS BY THE TRUST FLOATER TRANSACTIONS Alabama Fund $6,515,570 3.83% $130,860 Arkansas Fund 8,261,760 3.81% 164,909 California Fund 21,515,378 3.91% 439,603 Florida Fund 6,507,505 3.84% 131,574 Georgia Fund 4,512,840 3.92% 92,008 Maryland Fund 4,714,091 3.85% 95,605 Massachusetts Fund 15,772,915 3.93% 319,899 Primary and externally deposited inverse floaters held by the funds are not accounted for as secured borrowings. INDEMNIFICATIONS - Under each 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 each fund. Additionally, in the normal course of business, each fund enters into agreements with service providers that may contain indemnification clauses. Each fund's maximum exposure under these agreements is unknown as this would involve future claims that may be made against each fund that have not yet occurred. INVESTMENT TRANSACTIONS AND INCOME - Investment transactions are recorded on the trade date. 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. All premium and original issue discount is amortized or accreted for tax reporting purposes as required by federal income tax regulations. Each fund may receive proceeds from litigation settlements. Any proceeds received from litigation involving portfolio holdings are reflected in the Statements 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 Statements of Operations. 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 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. FEES PAID INDIRECTLY - Each fund's custody fee is reduced according to an arrangement that measures the value of cash deposited with the custodian by each fund. This amount, for the six months ended September 30, 2007, is shown as a reduction of total expenses on the Statements of Operations. TAX MATTERS AND DISTRIBUTIONS - Each 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. Accordingly, no provision for federal income tax is required in the financial statements. 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. Distributions in excess of net investment income or net realized gains are temporary overdistributions for financial statement purposes resulting from differences in the recognition or classification of income or distributions for financial statement and tax purposes.

In addition, these funds and other funds managed by MFS have established uncommitted borrowing arrangements with certain banks. 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 Federal Reserve funds rate plus 0.30%. In addition, a commitment fee, based on the average daily, unused portion of the committed line of credit, is allocated among the participating funds at the end of each calendar quarter. For the six months ended September 30, 2007, each fund's commitment fee and interest expense on the line of credit were as follows, and are included in miscellaneous expense on the Statements of Operations.

The Trustees consider matters bearing on the Funds and their advisory arrangements at their meetings throughout the year, including a review of performance data at each regular meeting. In addition, the independent Trustees met several times over the course of three months beginning in May and ending in July, 2007 ("contract review meetings") for the specific purpose of considering whether to approve the continuation of the investment advisory agreements for the Funds and the other investment companies that the Board oversees (the "MFS Funds"). The independent Trustees were assisted in their evaluation of the Funds' investment advisory agreements by independent legal counsel, from whom they received separate legal advice and with whom they met separately from MFS during various contract review meetings. The independent Trustees were also assisted in this process by the MFS Funds' Independent Chief Compliance Officer, a full-time senior officer appointed by and reporting to the independent Trustees. In connection with their deliberations regarding the continuation of the investment advisory agreements, the Trustees, including the independent Trustees, considered such information and factors as they believed, in light of the legal advice furnished to them and their own business judgment, to be relevant. The investment advisory agreement for each Fund was considered separately, although the Trustees also took into account the common interests of all MFS Funds in their review. As described below, the Trustees considered the nature, quality, and extent of the various investment advisory, administrative, and shareholder services performed by MFS under the existing investment advisory agreements and other arrangements with the Funds. In connection with their contract review meetings, the Trustees received and relied upon materials that included, among other items: (i) information provided by Lipper Inc. on the investment performance of the Funds for various time periods ended December 31, 2006 and the investment performance of a group of funds with substantially similar investment classifications/objectives (the "Lipper performance universe"), as well as the investment performance of a group of funds identified by objective criteria suggested by MFS ("MFS peer funds"), (ii) information provided by Lipper Inc. on the Funds' advisory fees and other expenses and the advisory fees and other expenses of comparable funds identified by Lipper (the "Lipper expense group"), as well as the advisory fees and other expenses of MFS peer funds, (iii) information provided by MFS on the advisory fees of comparable portfolios of other clients of MFS, including institutional separate accounts and other clients, (iv) information as to whether and to what extent applicable expense waivers, reimbursements or fee "breakpoints" are observed for the Funds, (v) information regarding MFS' financial results and financial condition, including MFS' and certain of its affiliates' estimated profitability from services performed for the Funds and the MFS Funds as a whole, (vi) MFS' views regarding the outlook for the mutual fund industry and the strategic business plans of MFS, (vii) descriptions of various functions performed by MFS for the Funds, such as compliance monitoring and portfolio trading practices, and (viii) information regarding the overall organization of MFS, including information about MFS' senior management and other personnel providing investment advisory, administrative and other services to the Funds and other MFS Funds. The comparative performance, fee and expense information prepared and provided by Lipper Inc. was not independently verified and the independent Trustees did not independently verify any information provided to them by MFS. The Trustees' conclusion as to the continuation of the investment advisory agreements with the Funds was based on a comprehensive consideration of all information provided to the Trustees and not the result of any single factor. Some of the factors that figured particularly in the Trustees' deliberations are described below, although individual Trustees may have evaluated the information presented differently from one another, giving different weights to various factors. It is also important to recognize that the fee arrangements for the Funds and other MFS Funds are the result of years of review and discussion between the independent Trustees and MFS, that certain aspects of such arrangements may receive greater scrutiny in some years than in others, and that the Trustees' conclusions may be based, in part, on their consideration of these same arrangements during the course of the year and in prior years. Based on information provided by Lipper Inc. and MFS, the Trustees reviewed each Fund's total return investment performance as well as the performance of peer groups of funds over various time periods. The Trustees placed particular emphasis on the total return performance of each Fund's Class A shares in comparison to the performance of funds in its respective Lipper performance universe over the three-year period ended December 31, 2006, which the Trustees believed was a long enough period to reflect differing market conditions. In assessing the reasonableness of each Fund's advisory fee, the Trustees considered, among other information, each Fund's advisory fee and the total expense ratio of each Fund's Class A shares as a percentage of average daily net assets and the advisory fee and total expense ratios of peer groups of funds based on information provided by Lipper Inc. and MFS. The Trustees considered whether the Funds were subject to any fee waivers or reductions or expense limitations. The Trustees considered that MFS observes an advisory fee reduction that will remain in effect for each Fund through February 28, 2009 as part of MFS' settlement with the New York Attorney General concerning market timing and related matters. The Trustees also considered the advisory fees charged by MFS to institutional accounts. In comparing these fees, the Trustees considered information provided by MFS as to the generally broader scope of services provided by MFS to the Funds in comparison to institutional accounts, the higher demands placed on MFS' investment personnel and trading infrastructure as a result of the daily cash in-flows and out-flows of the Funds, and the impact on MFS and expenses associated with the more extensive regulatory regime to which the Funds are subject in comparison to institutional accounts. The Trustees also considered whether each Fund is likely to benefit from any economies of scale in the management of the Fund in the event of growth in assets of the Fund. They noted that each Fund's advisory fee rate schedule is not currently subject to any breakpoints. Taking into account the advisory fee reduction noted above for the Funds, the Trustees determined not to recommend any advisory fee breakpoints for the Funds at this time. The Trustees also considered information prepared by MFS relating to MFS' costs and profits with respect to each Fund, the MFS Funds considered as a group, and other investment companies and accounts advised by MFS, as well as MFS' methodologies used to determine and allocate its costs to the MFS Funds, the Funds and other accounts and products for purposes of estimating profitability. After reviewing these and other factors described herein, the Trustees concluded, within the context of their overall conclusions regarding the investment advisory agreements, that the advisory fees charged to each Fund represent reasonable compensation in light of the services being provided by MFS to the Funds. In addition, the Trustees considered MFS' resources and related efforts to continue to retain, attract and motivate capable personnel to serve the Funds. The Trustees also considered current and developing conditions in the financial services industry, including the entry into the industry of large and well-capitalized companies which are spending, and appear to be prepared to continue to spend, substantial sums to engage personnel and to provide services to competing investment companies. In this regard, the Trustees also considered the financial resources of MFS and its ultimate parent, Sun Life Financial Inc. The Trustees also considered the advantages and possible disadvantages to the Funds of having an adviser that also serves other investment companies as well as other accounts. The Trustees also considered the nature, quality, cost, and extent of administrative, transfer agency, and distribution services provided to the Funds by MFS and its affiliates under agreements and plans other than the investment advisory agreements, including any 12b-1 fees the Funds pay to MFS Fund Distributors, Inc., an affiliate of MFS. The Trustees also considered the nature, extent and quality of certain other services MFS performs or arranges for on the Funds' behalf, which may include securities lending programs, directed expense payment programs, class action recovery programs, and MFS' interaction with third-party service providers, principally custodians and sub-custodians. The Trustees concluded that the various non-advisory services provided by MFS and its affiliates on behalf of the Funds were satisfactory. The Trustees also considered benefits to MFS from the use of the Funds' portfolio brokerage commissions, if applicable, to pay for investment research (excluding third-party research, for which MFS pays directly) and various other factors. Additionally, the Trustees considered so-called "fall-out benefits" to MFS such as reputational value derived from serving as investment manager to the Funds. Based on their evaluation of factors that they deemed to be material, including those factors described above, the Board of Trustees, including a majority of the independent Trustees, concluded that each Fund's investment advisory agreement with MFS should be continued for an additional one-year period, commencing August 1, 2007. MFS ALABAMA MUNICIPAL BOND FUND The total return performance of the Fund's Class A shares was in the 4th quintile relative to the other funds in the universe for the three-year period ended December 31, 2006 (the 1st quintile being the best performers and the 5th quintile being the worst performers). The total return performance of the Fund's Class A shares was in the 2nd quintile for each of the one- and five- year periods ended December 31, 2006 relative to the Lipper performance universe. Because of the passage of time, these performance results may differ from the performance results for more recent periods, including those shown elsewhere in this report. The Trustees expressed concern to MFS about the substandard investment performance of the Fund. In the course of their deliberations, the Trustees took into account information provided by MFS in connection with the contract review meetings, as well as during investment review meetings conducted with portfolio management personnel during the course of the year regarding the Fund's performance and its Lipper performance universe. After reviewing these and related factors, the Trustees concluded, within the context of their overall conclusions regarding the investment advisory agreement, that they were satisfied with MFS' responses and efforts relating to investment performance. In assessing the reasonableness of the Fund's advisory fee, the Trustees also considered that, according to the Lipper data (which takes into account the advisory fee reduction), the Fund's effective advisory fee rate was lower than the Lipper expense group median, and the Fund's total expense ratio was approximately at the Lipper expense group median.

Manning] Dear Shareholders: The past year has been a great example of why investors should keep their eyes on the long term. In 2006 the Dow Jones Industrial Average returned 19% and was fairly stable. This year we have seen a greater level of volatility than has been experienced in recent years. The Dow hit several new highs but also experienced swift drops as a global credit crisis swept through markets, spurred by defaults on U.S. subprime loans and a liquidity crunch. Still, even with this volatility, the Dow ended the first three quarters of 2007 with a return near 13%. U.S. Treasury bonds gained ground, especially in the third quarter as investors sought less risky asset classes. The spreads of many lower quality debt investments widened. In 2007 the U.S. dollar fell against the euro, oil prices have hit their highest levels yet, and gold has spiked to its steepest price in 28 years. Around the globe, stocks sold off as risk aversion mounted. As we have said before, markets can be volatile, and investors should make sure they have an investment plan that can carry them through the peaks and troughs. If you are focused on a long-term investment strategy, the short-term ups and downs of the markets should not necessarily dictate portfolio action on your part. In our view, investors who remain committed to a long-term plan are more likely to achieve their financial goals. In any market environment, we believe individual investors are best served by following a three- pronged investment strategy of allocating their holdings across the major asset classes, diversifying within each class, and regularly rebalancing their portfolios to maintain their desired allocations. Of course, these strategies cannot guarantee a profit or protect against a loss. Investing and planning for the long term require diligence and patience, two traits that in our experience are essential to capitalizing on the many opportunities the financial markets can offer -- through both up and down economic cycles.

(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. (i) For purposes of this presentation, the bond component includes both accrued interest amounts and the equivalent exposure from any derivative holdings, if applicable. (m) The average maturity shown is calculated using the final stated maturity on the portfolio's holdings without taking into account any holdings which have been pre-refunded or pre-paid to an earlier date or which have a mandatory put date prior to the stated maturity. The average life shown takes into account these earlier dates. (r) Each security is assigned a rating from Moody's Investors Service. If not rated by Moody's, the rating will be that assigned by Standard & Poor's. Likewise, if not assigned a rating by Standard & Poor's, it will be based on the rating assigned by Fitch, Inc. For those portfolios that hold a security which is not rated by any of the three agencies, the security is considered Not Rated. Holdings in U.S. Treasuries and government agency mortgage-backed securities, if any, are included in the "AAA"-rating category. Percentages are based on the total market value of investments as of 09/30/07. From time to time "cash and other net assets" may be negative due to timing of cash receipts and/or equivalent exposure from any derivative holdings. Percentages are based on net assets as of 09/30/07, unless otherwise noted. The portfolio is actively managed and current holdings may be different.

EXPENSE TABLES FUND EXPENSES BORNE BY THE SHAREHOLDERS DURING THE PERIOD, APRIL 1, 2007, THROUGH SEPTEMBER 30, 2007 As a shareholder of the funds, you incur two types of costs: (1) transaction costs, including sales charges (loads) on certain purchase or redemption payments, and (2) ongoing costs, including management fees; distribution and service (12b-1) fees; and other fund expenses. These examples are intended to help you understand your ongoing costs (in dollars) of investing in the funds and to compare these costs with the ongoing costs of investing in other mutual funds. These examples are based on an investment of $1,000 invested at the beginning of the period and held for the entire period April 1, 2007 through September 30, 2007. ACTUAL EXPENSES The first line for each share class in the following tables provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The second line for each share class in the following tables provides information about hypothetical account values and hypothetical expenses based on each fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in each fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads). Therefore, the second line for each share class in the tables is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

(s) From time to time the fund may receive proceeds from litigation settlements, without which performance would be lower. (t) Total returns do not include any applicable sales charges. (z) The fund applied a change in estimate for amortization of premium on certain debt securities that resulted in an increase of $0.01 per share to net investment income, a decrease of $0.01 per share to net realized and unrealized gain (loss) on investments, and an increase of 0.07% to the net investment income ratio for each class for the year ended March 31, 2007.

(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 revenues and expenses during the reporting period. Actual results could differ from those estimates. Because each fund invests primarily in the securities of a single state and its political subdivisions, each fund is vulnerable to the effects of changes in the legal and economic environment of the particular state. Municipal securities backed by current or anticipated revenues from a specific project or specific assets can be negatively affected by the discontinuance of the taxation supporting the projects or assets or the inability to collect revenues for the project or from the assets. If the Internal Revenue Service determines an issuer of a municipal security has not complied with applicable tax requirements, the security could decline in value, interest from the security could become taxable and each fund may be required to issue Form 1099-DIV. INVESTMENT VALUATIONS - Debt instruments (other than short-term instruments), including restricted debt instruments, are generally valued at an evaluated or composite bid as reported by an independent 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. Swaps are generally valued at an evaluated bid as reported by an independent pricing service. Securities and other assets generally valued on the basis of information from an independent pricing service may also be valued at a broker-dealer bid quotation. Values obtained from pricing services can utilize both dealer-supplied valuations and electronic data processing techniques, which take into account factors such as institutional-size trading in similar groups of securities, yield, quality, coupon rate, maturity, type of issue, trading characteristics, and other market data. The Board of Trustees has delegated primary responsibility for determining or causing to be determined the value of each fund's investments (including any fair valuation) to the adviser pursuant to valuation policies and procedures approved by the Board. If the adviser determines that reliable market quotations are not readily available, investments are valued at fair value as determined in good faith by the adviser in accordance with such procedures under the oversight of the Board of Trustees. Under each fund's valuation policies and procedures, market quotations are not considered to be readily available for many types of debt instruments and certain types of derivatives. These investments are generally valued at fair value based on information from independent pricing services. In addition, investments may be valued at fair value if the adviser determines that an 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 each fund's net asset value, or after the halting 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 may rely on independent 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 each fund's net asset value can differ depending on the source and method used to determine value. When fair valuation is used, the value of investments used to determine each fund's net asset value may differ from quoted or published prices for the same investments. In September 2006, FASB Statement No. 157, Fair Value Measurements (the "Statement") was issued, and is effective for fiscal years beginning after November 15, 2007 and for all interim periods within those fiscal years. This Statement provides a single definition of fair value, a hierarchy for measuring fair value and expanded disclosures about fair value measurements. Management is evaluating the application of the Statement to each fund, and believes the impact will be limited to expanded disclosures resulting from the adoption of this Statement in each fund's financial statements. DERIVATIVE RISK - Each fund may invest in derivatives for hedging or non- hedging purposes. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains. When the funds use derivatives as an investment to gain market exposure, or for hedging purposes, gains and losses from derivative instruments may be substantially greater than the derivative's original cost. Derivative instruments include swap agreements. SWAP AGREEMENTS - Each fund may enter into swap agreements. A swap is an exchange of cash payments between each fund and another party. Net cash payments are exchanged at specified intervals and are recorded as a realized gain or loss in the Statements of Operations. The value of the swap is adjusted daily and the change in value, including accruals of periodic amounts of interest to be paid or received, is recorded as unrealized appreciation or depreciation in the Statements of Operations. A liquidation payment received or made upon early termination is recorded as a realized gain or loss in the Statements of Operations. Collateral, in the form of cash or securities, may be required to be held in segregated accounts with each fund's custodian in connection with these agreements. Risk of loss may exceed amounts recognized on the Statements of Assets and Liabilities. These risks include the possible lack of a liquid market, failure of the counterparty to perform under the terms of the agreements, and unfavorable market movement of the underlying instrument. All swap agreements entered into by each fund with the same counterparty are generally governed by a single master agreement, which provides for the netting of all amounts owed by the parties under the agreement upon the occurrence of an event of default, thereby reducing the credit risk to which such party is exposed. Each fund holds interest rate swap agreements which involve the periodic exchange of cash flows, such as the exchange of fixed rate interest payments for floating rate interest payments based on a notional principal amount. The interest rates may be based on a specific financial index or the exchange of two distinct floating rate payments. Each fund may enter into an interest rate swap in order to manage its exposure to interest rate fluctuations. INVERSE FLOATERS - The funds may invest in municipal inverse floating rate securities which are structured by the issuer (known as primary market inverse floating rate securities) or by an investment banker utilizing municipal bonds which have already been issued (known as secondary market inverse floating rate securities) to have variable rates of interest which typically move in the opposite direction of short term interest rates. A secondary market inverse floating rate security is created when an investment banker transfers a fixed rate municipal bond to a special purpose trust, and causes the trust to (a) issue floating rate certificates to third parties, in an amount equal to a fraction of the par amount of the deposited bonds (these certificates usually pay tax-exempt interest at short-term interest rates that typically reset weekly; and the certificate holders typically, on seven days notice, have the option to tender their certificates to the investment banker or another party for redemption at par plus accrued interest), and (b) issue inverse floating rate certificates (sometimes referred to as "inverse floaters"). If the holder of the inverse floater transfers the municipal bonds to an investment banker for the purpose of depositing the municipal bonds into the special purpose trust, the inverse floating rate certificates that are issued by the trust are referred to as "self-deposited inverse floaters." If the bonds held by the trust are purchased by the investment banker for deposit into the trust from someone other than the purchasers of the inverse floaters, the inverse floating rate certificates that are issued by the trust are referred to as "externally deposited inverse floaters." Such self-deposited inverse floaters held by the funds are accounted for as secured borrowings, with the municipal bonds reflected in the investments of the funds and amounts owed to the holder of the floating rate certificate under the provisions of the trust, which amounts are paid solely from the assets of the trust, reflected as liabilities of the funds in the Statements of Assets and Liabilities under the caption, "Payable to the holder of the floating rate certificate from trust assets". Interest expense and fees relate to payments made to the holder of the floating rate certificate from trust assets in connection with self-deposited inverse floater transactions. Interest expense and fees are recorded as incurred. At September 30, 2007, each fund's payable to the holder of the floating rate certificate from trust assets, the weighted average interest rate on the floating rate certificates issued by the trust, and the interest expense and fees in connection with self-deposited inverse floaters were as follows: WEIGHTED AVERAGE PAYABLE TO THE HOLDER INTEREST RATE ON INTEREST EXPENSE AND OF THE FLOATING RATE FLOATING RATE FEES IN CONNECTION CERTIFICATE FROM CERTIFICATES ISSUED WITH SELF-DEPOSITED FUND TRUST ASSETS BY THE TRUST INVERSE FLOATERS Mississippi Fund $5,369,389 3.78% $108,046 New York Fund 10,390,083 3.87% 211,049 North Carolina Fund 21,510,180 3.86% 432,563 Pennsylvania Fund 6,179,154 3.79% 124,549 South Carolina Fund 9,303,676 3.86% 177,653 Tennessee Fund -- -- -- Virginia Fund 15,704,685 3.84% 308,356 West Virginia Fund 9,704,237 3.88% 195,544 Primary and externally deposited inverse floaters held by each fund are not accounted for as secured borrowings. INDEMNIFICATIONS - Under each 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 each fund. Additionally, in the normal course of business, each fund enters into agreements with service providers that may contain indemnification clauses. Each fund's maximum exposure under these agreements is unknown as this would involve future claims that may be made against each fund that have not yet occurred. INVESTMENT TRANSACTIONS AND INCOME - Investment transactions are recorded on the trade date. 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. All premium and original issue discount is amortized or accreted for tax reporting purposes as required by federal income tax regulations. Each fund may receive proceeds from litigation settlements. Any proceeds received from litigation involving portfolio holdings are reflected in the Statements 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 Statements of Operations. 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 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. FEES PAID INDIRECTLY - Each fund's custody fee is reduced according to an arrangement that measures the value of cash deposited with the custodian by each fund. This amount, for the six months ended September 30, 2007, is shown as a reduction of total expenses on the Statements of Operations. TAX MATTERS AND DISTRIBUTIONS - Each 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. Accordingly, no provision for federal income tax is required in the financial statements. 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. Distributions in excess of net investment income or net realized gains are temporary overdistributions for financial statement purposes resulting from differences in the recognition or classification of income or distributions for financial statement and tax purposes. Book/tax differences primarily relate to amortization and accretion of debt securities and secured borrowings. 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 is as follows: NORTH SOUTH WEST MISSISSIPPI NEW YORK CAROLINA PENNSYLVANIA CAROLINA TENNESSEE VIRGINIA VIRGINIA YEAR ENDED 3/31/07 FUND FUND FUND FUND FUND FUND FUND FUND Ordinary income (including any short-term capital gains) $-- $104,521 $346,482 $-- $-- $-- $-- $-- Tax-exempt income 3,631,591 6,685,340 13,384,867 4,238,983 6,317,237 4,576,148 12,629,190 5,754,974 Long-term capital gain -- 649,124 468,510 -- -- 50,469 76,004 885,826 - ----------------------------------------------------------------------------------------------------------------------------------- Total distributions $3,631,591 $7,438,985 $14,199,859 $4,238,983 $6,317,237 $4,626,617 $12,705,194 $6,640,800 The federal tax cost and the tax basis components of distributable earnings were as follows: NORTH SOUTH WEST MISSISSIPPI NEW YORK CAROLINA PENNSYLVANIA CAROLINA TENNESSEE VIRGINIA VIRGINIA AS OF 9/30/07 FUND FUND FUND FUND FUND FUND FUND FUND Cost of investments $81,419,709 $147,724,702 $297,732,849 $102,246,737 $143,587,890 $102,477,412 $261,979,566 $129,254,276 - ----------------------------------------------------------------------------------------------------------------------------------- Gross appreciation $2,850,602 $8,294,657 $14,867,677 $3,662,829 $6,964,669 $4,195,765 $10,583,338 $4,609,570 Gross depreciation (312,738) (553,559) (1,461,776) (445,431) (550,467) (507,314) (1,197,135) (327,787) - ----------------------------------------------------------------------------------------------------------------------------------- Net unrealized appreciation (depreciation) $2,537,864 $7,741,098 $13,405,901 $3,217,398 $6,414,202 $3,688,451 $9,386,203 $4,281,783 AS OF 3/31/07 Undistributed ordinary income $-- $187,567 $-- $-- $-- $244,063 $299,075 $39,337 Undistributed tax-exempt income 327,310 335,398 661,555 282,638 663,073 389,769 436,285 499,730 Undistributed long-term capital gain -- 40,347 380,172 27,487 -- 85,332 242,917 65,284 Capital loss carryforwards (226,449) -- -- -- (395,472) -- -- -- Post-October capital loss deferral -- -- -- -- -- -- -- (2,702) Other temporary differences (293,833) (535,287) (1,034,654) (309,282) (521,547) (383,052) (1,053,991) (448,613) Net unrealized appreciation/ depreciation 3,582,700 10,240,319 18,296,181 4,555,239 8,730,095 5,156,115 13,547,294 6,120,454 The aggregate cost above includes prior fiscal year end tax adjustments.

All shareholders bear the common expenses of each fund based on the value of settled shares outstanding of each class, without distinction between share classes. Dividends are declared separately for each class. Differences in per share dividend rates are generally due to differences in separate class expenses. Class B shares will convert to Class A shares approximately eight years after purchase. (3) TRANSACTIONS WITH AFFILIATES INVESTMENT ADVISER - Each fund has an investment advisory agreement with Massachusetts Financial Services Company (MFS) to provide overall investment management and related administrative services and facilities to each fund. The management fee is computed daily and paid monthly at an annual rate of 0.55% of each fund's average daily net assets. As part of a settlement agreement with the New York Attorney General concerning market timing and related matters, MFS has agreed to reduce the management fee to 0.30% of each fund's average daily net assets for the period March 1, 2004 through February 28, 2009. For the six months ended September 30, 2007, this waiver amounted to the following for each fund and is reflected as a reduction of total expenses in the Statement of Operations.

For the Pennsylvania Fund, the investment adviser has agreed in writing to pay a portion of the funds operating expenses exclusive of management, distribution and service, and certain other fees and expenses, such that operating expenses do not exceed 0.20% annually of the fund's average daily net assets. This written agreement will continue through July 31, 2008, unless changed or rescinded by the Board of Trustees. For the six months ended September 30, 2007 this reduction amounted to $18,820 and is reflected as a reduction of total expenses in the Statement of Operations. DISTRIBUTOR - MFS Fund Distributors, Inc. (MFD), a wholly-owned subsidiary of MFS, as distributor, received the following amounts for the six months ended September 30, 2007, as its portion of the initial sales charge on sales of Class A shares of each fund.

Each fund's distribution plan provides that each fund will pay MFD for services provided by MFD and financial intermediaries in connection with the distribution and servicing of certain share classes. One component of the plan is a distribution fee paid to MFD and another component of the plan is a service fee paid to MFD. MFD may subsequently pay all, or a portion, of the distribution and/or service fees to financial intermediaries.

In addition, these funds and other funds managed by MFS have established uncommitted borrowing arrangements with certain banks. 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 Federal Reserve funds rate plus 0.30%. In addition, a commitment fee, based on the average daily, unused portion of the committed line of credit, is allocated among the participating funds at the end of each calendar quarter. For the six months ended September 30, 2007, each fund's commitment fee and interest expense on the line of credit were as follows, and are included in miscellaneous expense on the Statements of Operations.

The Trustees consider matters bearing on the Funds and their advisory arrangements at their meetings throughout the year, including a review of performance data at each regular meeting. In addition, the independent Trustees met several times over the course of three months beginning in May and ending in July, 2007 ("contract review meetings") for the specific purpose of considering whether to approve the continuation of the investment advisory agreements for the Funds and the other investment companies that the Board oversees (the "MFS Funds"). The independent Trustees were assisted in their evaluation of the Funds' investment advisory agreements by independent legal counsel, from whom they received separate legal advice and with whom they met separately from MFS during various contract review meetings. The independent Trustees were also assisted in this process by the MFS Funds' Independent Chief Compliance Officer, a full-time senior officer appointed by and reporting to the independent Trustees. In connection with their deliberations regarding the continuation of the investment advisory agreements, the Trustees, including the independent Trustees, considered such information and factors as they believed, in light of the legal advice furnished to them and their own business judgment, to be relevant. The investment advisory agreement for each Fund was considered separately, although the Trustees also took into account the common interests of all MFS Funds in their review. As described below, the Trustees considered the nature, quality, and extent of the various investment advisory, administrative, and shareholder services performed by MFS under the existing investment advisory agreements and other arrangements with the Funds. In connection with their contract review meetings, the Trustees received and relied upon materials that included, among other items: (i) information provided by Lipper Inc. on the investment performance of the Funds for various time periods ended December 31, 2006 and the investment performance of a group of funds with substantially similar investment classifications/objectives (the "Lipper performance universe"), as well as the investment performance of a group of funds identified by objective criteria suggested by MFS ("MFS peer funds"), (ii) information provided by Lipper Inc. on the Funds' advisory fees and other expenses and the advisory fees and other expenses of comparable funds identified by Lipper (the "Lipper expense group"), as well as the advisory fees and other expenses of MFS peer funds, (iii) information provided by MFS on the advisory fees of comparable portfolios of other clients of MFS, including institutional separate accounts and other clients, (iv) information as to whether and to what extent applicable expense waivers, reimbursements or fee "breakpoints" are observed for the Funds, (v) information regarding MFS' financial results and financial condition, including MFS' and certain of its affiliates' estimated profitability from services performed for the Funds and the MFS Funds as a whole, (vi) MFS' views regarding the outlook for the mutual fund industry and the strategic business plans of MFS, (vii) descriptions of various functions performed by MFS for the Funds, such as compliance monitoring and portfolio trading practices, and (viii) information regarding the overall organization of MFS, including information about MFS' senior management and other personnel providing investment advisory, administrative and other services to the Funds and other MFS Funds. The comparative performance, fee and expense information prepared and provided by Lipper Inc. was not independently verified and the independent Trustees did not independently verify any information provided to them by MFS. The Trustees' conclusion as to the continuation of the investment advisory agreements with the Funds was based on a comprehensive consideration of all information provided to the Trustees and not the result of any single factor. Some of the factors that figured particularly in the Trustees' deliberations are described below, although individual Trustees may have evaluated the information presented differently from one another, giving different weights to various factors. It is also important to recognize that the fee arrangements for the Funds and other MFS Funds are the result of years of review and discussion between the independent Trustees and MFS, that certain aspects of such arrangements may receive greater scrutiny in some years than in others, and that the Trustees' conclusions may be based, in part, on their consideration of these same arrangements during the course of the year and in prior years. Based on information provided by Lipper Inc. and MFS, the Trustees reviewed each Fund's total return investment performance as well as the performance of peer groups of funds over various time periods. The Trustees placed particular emphasis on the total return performance of each Fund's Class A shares in comparison to the performance of funds in its respective Lipper performance universe over the three-year period ended December 31, 2006, which the Trustees believed was a long enough period to reflect differing market conditions. In assessing the reasonableness of each Fund's advisory fee, the Trustees considered, among other information, each Fund's advisory fee and the total expense ratio of each Fund's Class A shares as a percentage of average daily net assets and the advisory fee and total expense ratios of peer groups of funds based on information provided by Lipper Inc. and MFS. The Trustees considered whether the Funds were subject to any fee waivers or reductions or expense limitations. The Trustees considered that MFS observes an advisory fee reduction that will remain in effect for each Fund through February 28, 2009 as part of MFS' settlement with the New York Attorney General concerning market timing and related matters. The Trustees also considered the advisory fees charged by MFS to institutional accounts. In comparing these fees, the Trustees considered information provided by MFS as to the generally broader scope of services provided by MFS to the Funds in comparison to institutional accounts, the higher demands placed on MFS' investment personnel and trading infrastructure as a result of the daily cash in-flows and out-flows of the Funds, and the impact on MFS and expenses associated with the more extensive regulatory regime to which the Funds are subject in comparison to institutional accounts. The Trustees also considered whether each Fund is likely to benefit from any economies of scale in the management of the Fund in the event of growth in assets of the Fund. They noted that each Fund's advisory fee rate schedule is not currently subject to any breakpoints. Taking into account the advisory fee reduction noted above for the Funds, and any expense limitations, the Trustees determined not to recommend any advisory fee breakpoints for the Funds at this time. The Trustees also considered information prepared by MFS relating to MFS' costs and profits with respect to each Fund, the MFS Funds considered as a group, and other investment companies and accounts advised by MFS, as well as MFS' methodologies used to determine and allocate its costs to the MFS Funds, the Funds and other accounts and products for purposes of estimating profitability. After reviewing these and other factors described herein, the Trustees concluded, within the context of their overall conclusions regarding the investment advisory agreements, that the advisory fees charged to each Fund represent reasonable compensation in light of the services being provided by MFS to the Funds. In addition, the Trustees considered MFS' resources and related efforts to continue to retain, attract and motivate capable personnel to serve the Funds. The Trustees also considered current and developing conditions in the financial services industry, including the entry into the industry of large and well-capitalized companies which are spending, and appear to be prepared to continue to spend, substantial sums to engage personnel and to provide services to competing investment companies. In this regard, the Trustees also considered the financial resources of MFS and its ultimate parent, Sun Life Financial Inc. The Trustees also considered the advantages and possible disadvantages to the Funds of having an adviser that also serves other investment companies as well as other accounts. The Trustees also considered the nature, quality, cost, and extent of administrative, transfer agency, and distribution services provided to the Funds by MFS and its affiliates under agreements and plans other than the investment advisory agreements, including any 12b-1 fees the Funds pay to MFS Fund Distributors, Inc., an affiliate of MFS. The Trustees also considered the nature, extent and quality of certain other services MFS performs or arranges for on the Funds' behalf, which may include securities lending programs, directed expense payment programs, class action recovery programs, and MFS' interaction with third-party service providers, principally custodians and sub-custodians. The Trustees concluded that the various non-advisory services provided by MFS and its affiliates on behalf of the Funds were satisfactory. The Trustees also considered benefits to MFS from the use of the Funds' portfolio brokerage commissions, if applicable, to pay for investment research (excluding third-party research, for which MFS pays directly) and various other factors. Additionally, the Trustees considered so-called "fall-out benefits" to MFS such as reputational value derived from serving as investment manager to the Funds. Based on their evaluation of factors that they deemed to be material, including those factors described above, the Board of Trustees, including a majority of the independent Trustees, concluded that each Fund's investment advisory agreement with MFS should be continued for an additional one-year period, commencing August 1, 2007. MFS MISSISSIPPI MUNICIPAL BOND FUND The total return performance of the Fund's Class A shares was in the 2nd quintile relative to the other funds in the universe for the three-year period ended December 31, 2006 (the 1st quintile being the best performers and the 5th quintile being the worst performers).

In assessing the reasonableness of the Fund's advisory fee, the Trustees also considered that, according to the Lipper data (which takes into account the advisory fee reduction), the Fund's effective advisory fee rate was lower than the Lipper expense group median, and the Fund's total expense ratio was higher than the Lipper expense group median. MFS WEST VIRGINIA MUNICIPAL BOND FUND The total return performance of the Fund's Class A shares was in the 2nd quintile relative to the other funds in the universe for the three-year period ended December 31, 2006 (the 1st quintile being the best performers and the 5th quintile being the worst performers). The total return performance of the Fund's Class A shares was in the 3rd quintile for each of the one- and five- year periods ended December 31, 2006 relative to the Lipper performance universe. Because of the passage of time, these performance results may differ from the performance results for more recent periods, including those shown elsewhere in this report.

Manning] Dear Shareholders: The past year has been a great example of why investors should keep their eyes on the long term. In 2006 the Dow Jones Industrial Average returned 19% and was fairly stable. This year we have seen a greater level of volatility than has been experienced in recent years. The Dow hit several new highs but also experienced swift drops as a global credit crisis swept through markets, spurred by defaults on U.S. subprime loans and a liquidity crunch. Still, even with this volatility, the Dow ended the first three quarters of 2007 with a return near 13%. U.S. Treasury bonds gained ground, especially in the third quarter as investors sought less risky asset classes. The spreads of many lower quality debt investments widened. In 2007 the U.S. dollar fell against the euro, oil prices have hit their highest levels yet, and gold has spiked to its steepest price in 28 years. Around the globe, stocks sold off as risk aversion mounted. As we have said before, markets can be volatile, and investors should make sure they have an investment plan that can carry them through the peaks and troughs. If you are focused on a long-term investment strategy, the short-term ups and downs of the markets should not necessarily dictate portfolio action on your part. In our view, investors who remain committed to a long-term plan are more likely to achieve their financial goals. In any market environment, we believe individual investors are best served by following a three-pronged investment strategy of allocating their holdings across the major asset classes, diversifying within each class, and regularly rebalancing their portfolios to maintain their desired allocations. Of course, these strategies cannot guarantee a profit or protect against a loss. Investing and planning for the long term require diligence and patience, two traits that in our experience are essential to capitalizing on the many opportunities the financial markets can offer -- through both up and down economic cycles. Respectfully, /s/ Robert J. Manning Robert J. Manning Chief Executive Officer and Chief Investment Officer MFS Investment Management(R) November 15, 2007 The opinions expressed in this letter are subject to change, may not be relied upon for investment advice, and no forecasts can be guaranteed.

(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. (i) For purposes of this presentation, the bond component includes both accrued interest amounts and the equivalent exposure from any derivative holdings, if applicable. (m) The average maturity shown is calculated using the final stated maturity on the portfolio's holdings without taking into account any holdings which have been pre-refunded or pre-paid to an earlier date or which have a mandatory put date prior to the stated maturity. The average life shown takes into account these earlier dates. (o) Less than 0.1%. (r) Each security is assigned a rating from Moody's Investors Service. If not rated by Moody's, the rating will be that assigned by Standard & Poor's. Likewise, if not assigned a rating by Standard & Poor's, it will be based on the rating assigned by Fitch, Inc. For those portfolios that hold a security which is not rated by any of the three agencies, the security is considered Not Rated. Holdings in U.S. Treasuries and government agency mortgage-backed securities, if any, are included in the "AAA"-rating category. Percentages are based on the total market value of investments as of 09/30/07. From time to time "Cash & Other Net Assets" may be negative due to timing of cash receipts and/or equivalent exposure from any derivative holdings. Percentages are based on net assets as of 09/30/07, unless otherwise noted. The portfolio is actively managed and current holdings may be different. EXPENSE TABLE Fund Expenses Borne by the Shareholders During the Period, April 1, 2007 through September 30, 2007 As a shareholder of the fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on certain purchase or redemption payments and (2) ongoing costs, including management fees; distribution and service (12b-1) fees; and other fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period April 1, 2007 through September 30, 2007. ACTUAL EXPENSES The first line for each share class in the following table provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The second line for each share class in the following table provides information about hypothetical account values and hypothetical expenses based on the fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads). Therefore, the second line for each share class in the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. - -------------------------------------------------------------------------------- Expenses Paid During Annualized Beginning Ending Period(p) Share Expense Account Value Account Value 4/01/07- Class Ratio 4/01/07 9/30/07 9/30/07 - -------------------------------------------------------------------------------- Actual 0.90% $1,000.00 $1,010.70 $4.52 A ------------------------------------------------------------------------ Hypothetical (h) 0.90% $1,000.00 $1,020.50 $4.55 - -------------------------------------------------------------------------------- Actual 1.65% $1,000.00 $1,005.80 $8.27 B ------------------------------------------------------------------------ Hypothetical (h) 1.65% $1,000.00 $1,016.75 $8.32 - -------------------------------------------------------------------------------- Actual 1.65% $1,000.00 $1,007.00 $8.28 C ------------------------------------------------------------------------ Hypothetical (h) 1.65% $1,000.00 $1,016.75 $8.32 - -------------------------------------------------------------------------------- Actual (i) 0.62% $1,000.00 $1,019.80 $1.69 A1 ------------------------------------------------------------------------ Hypothetical (h) 0.62% $1,000.00 $1,021.90 $3.13 - -------------------------------------------------------------------------------- Actual (i) 1.39% $1,000.00 $1,017.70 $3.79 B1 ------------------------------------------------------------------------ Hypothetical (h) 1.39% $1,000.00 $1,018.05 $7.01 - -------------------------------------------------------------------------------- (h) 5% class return per year before expenses. (i) For the period of the class' inception, June 25, 2007 through the stated period end. (p) Expenses paid is equal to each class' annualized expense ratio, as shown above, multiplied by the average account value over the period, multiplied by the number of days in the period, divided by the number of days in the year. Expenses paid do not include any applicable sales charges (loads). If these transaction costs had been included, your costs would have been higher.

(a) Annualized. (d) Per share data are based on average shares outstanding. (f) Ratios do not reflect reductions from fees paid indirectly. (g) The per share amount is not in accordance with the net realized and unrealized gain/loss for the period because of the timing of sales of fund shares and the per share amount of realized and unrealized gains and losses at such time. (i) For the period from the class' inception, June 25, 2007 (Classes A1 and B1) through the stated period end. (l) Interest expense and fees relate to payments made to the holder of the floating rate certificate from trust assets. (n) Not annualized. (r) Certain expenses have been reduced without which performance would have been lower. (s) From time to time the fund may receive proceeds from litigation settlements, without which performance would be lower. (t) Total returns do not include any applicable sales charges. (w) Per share amount was less than $0.01. (z) The fund applied a change in estimate for amortization of premium on certain debt securities in the year ended March 31, 2007 that resulted in an increase of $0.03 per share to net investment income, a decrease of $0.03 per share to net realized and unrealized gain (loss) on investments, and an increase of 0.30% to the net investment income ratio for Class A, Class B and Class C. The change in estimate had no impact on net assets, net asset value per share or total return of each class. SEE NOTES TO FINANCIAL STATEMENTS NOTES TO FINANCIAL STATEMENTS (unaudited) (1) BUSINESS AND ORGANIZATION MFS Municipal Income Fund (the fund) is a series of MFS Municipal Series Trust which is organized as a Massachusetts business trust and is registered under the Investment Company Act of 1940, as amended, as an open-end management investment company. (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 revenues and expenses during the reporting period. Actual results could differ from those estimates. Municipal securities backed by current or anticipated revenues from a specific project or specific assets can be negatively affected by the discontinuance of the taxation supporting the projects or assets or the inability to collect revenues for the project or from the assets. If the Internal Revenue Service determines an issuer of a municipal security has not complied with applicable tax requirements, the security could decline in value, interest from the security could become taxable and the fund may be required to issue Forms 1099-DIV. INVESTMENT VALUATIONS - Debt instruments (other than short-term instruments), including restricted debt instruments, are generally valued at an evaluated or composite bid as reported by an independent 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. Swaps are generally valued at an evaluated bid as reported by an independent pricing service. Securities and other assets generally valued on the basis of information from an independent pricing service may also be valued at a broker-dealer bid quotation. Values obtained from pricing services can utilize both dealer-supplied valuations and electronic data processing techniques, which take into account factors such as institutional-size trading in similar groups of securities, yield, quality, coupon rate, maturity, type of issue, trading characteristics, and other market data. The Board of Trustees has delegated primary responsibility for determining or causing to be determined the value of the fund's investments (including any fair valuation) to the adviser pursuant to valuation policies and procedures approved by the Board. If the adviser determines that reliable market quotations are not readily available, investments are valued at fair value as determined in good faith by the adviser in accordance with such procedures under the oversight of the Board of Trustees. Under the fund's valuation policies and procedures, market quotations are not considered to be readily available for many types of debt instruments and certain types of derivatives. These investments are generally valued at fair value based on information from independent pricing services. In addition, investments may be valued at fair value if the adviser determines that an 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 halting 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 may rely on independent 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 on the source and method used to determine value. When fair valuation is used, the value of investments used to determine the fund's net asset value may differ from quoted or published prices for the same investments. In September 2006, FASB Statement No. 157, Fair Value Measurements (the "Statement") was issued, and is effective for fiscal years beginning after November 15, 2007 and for all interim periods within those fiscal years. This Statement provides a single definition of fair value, a hierarchy for measuring fair value and expanded disclosures about fair value measurements. Management is evaluating the application of the Statement to the fund, and believes the impact will be limited to expanded disclosures resulting from the adoption of this Statement in the fund's financial statements. DERIVATIVE RISK - The fund may invest in derivatives for hedging or non-hedging purposes. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains. When the fund uses derivatives as an investment to gain market exposure, or for hedging purposes, gains and losses from derivative instruments may be substantially greater than the derivative's original cost. Derivative instruments include swap agreements. SWAP AGREEMENTS - The fund may enter into swap agreements. A swap is an exchange of cash payments between the fund and another party. Net cash payments are exchanged at specified intervals and are recorded as a realized gain or loss in the Statement of Operations. The value of the swap is adjusted daily and the change in value, including accruals of periodic amounts of interest to be paid or received, is recorded as unrealized appreciation or depreciation in the Statement of Operations. A liquidation payment received or made upon early termination is recorded as a realized gain or loss in the Statement of Operations. Collateral, in the form of cash or securities, may be required to be held in segregated accounts with the fund's custodian in connection with these agreements. Risk of loss may exceed amounts recognized on the Statement of Assets and Liabilities. These risks include the possible lack of a liquid market, failure of the counterparty to perform under the terms of the agreements, and unfavorable market movement of the underlying instrument. All swap agreements entered into by the fund with the same counterparty are generally governed by a single master agreement, which provides for the netting of all amounts owed by the parties under the agreement upon the occurrence of an event of default, thereby reducing the credit risk to which such party is exposed. The fund holds interest rate swap agreements which involve the periodic exchange of cash flows, such as the exchange of fixed rate interest payments for floating rate interest payments based on a notional principal amount. The interest rates may be based on a specific financial index or the exchange of two distinct floating rate payments. The fund may enter into an interest rate swap in order to manage its exposure to interest rate fluctuations. INVERSE FLOATERS - The fund invests in municipal inverse floating rate securities which are structured by the issuer (known as primary market inverse floating rate securities) or by an investment banker utilizing municipal bonds which have already been issued (known as secondary market inverse floating rate securities) to have variable rates of interest which typically move in the opposite direction of short term interest rates. A secondary market inverse floating rate security is created when an investment banker transfers a fixed rate municipal bond to a special purpose trust, and causes the trust to (a) issue floating rate certificates to third parties, in an amount equal to a fraction of the par amount of the deposited bonds (these certificates usually pay tax-exempt interest at short-term interest rates that typically reset weekly; and the certificate holders typically, on seven days notice, have the option to tender their certificates to the investment banker or another party for redemption at par plus accrued interest), and (b) issue inverse floating rate certificates (sometimes referred to as "inverse floaters"). If the holder of the inverse floater transfers the municipal bonds to an investment banker for the purpose of depositing the municipal bonds into the special purpose trust, the inverse floating rate certificates that are issued by the trust are referred to as "self-deposited inverse floaters." If the bonds held by the trust are purchased by the investment banker for deposit into the trust from someone other than the purchasers of the inverse floaters, the inverse floating rate certificates that are issued by the trust are referred to as "externally deposited inverse floaters." Such self-deposited inverse floaters held by the fund are accounted for as secured borrowings, with the municipal bonds reflected in the investments of the fund and amounts owed to the holder of the floating rate certificate under the provisions of the trust, which amounts are paid solely from the assets of the trust, reflected as liabilities of the fund in the Statement of Assets and Liabilities under the caption, "Payable to the holder of the floating rate certificate from trust assets". At September 30, 2007, the fund's payable to the holder of the floating rate certificate from trust assets was $76,043,487. The weighted average interest rate on the floating rate certificates issued by the trust was 3.88%. Interest expense and fees relate to payments made to the holder of the floating rate certificate from trust assets in connection with self-deposited inverse floater transactions. Interest expense and fees are recorded as incurred. For the six months ended September 30, 2007, interest expense and fees in connection with self-deposited inverse floaters was $851,855. Primary and externally deposited inverse floaters held by the fund are not accounted for as secured borrowings. 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 - Investment transactions are recorded on the trade date. 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. All premium and original issue discount is amortized or accreted for tax reporting purposes as required by federal income tax regulations. 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. 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 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. FEES PAID INDIRECTLY - The fund's custody fee is reduced according to an arrangement that measures the value of cash deposited with the custodian by the fund. This amount, for the six months ended September 30, 2007, is shown as a reduction of total expenses on the Statement of Operations. 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. Accordingly, no provision for federal income tax is required in the financial statements. 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. Distributions in excess of net investment income or net realized gains are temporary overdistributions for financial statement purposes resulting from differences in the recognition or classification of income or distributions for financial statement and tax purposes. Book/tax differences primarily relate to amortization and accretion of debt securities and secured borrowings. 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 is as follows: 3/31/07 Ordinary income (including any short-term capital gains) $24,400 Tax-exempt income 13,891,572 - --------------------------------------------------------------------- Total distributions $13,915,972 The federal tax cost and the tax basis components of distributable earnings were as follows: AS OF 9/30/07 Cost of investments $1,189,530,988 ----------------------------------------------------------- Gross appreciation $75,334,449 Gross depreciation (8,180,883) ----------------------------------------------------------- Net unrealized appreciation (depreciation) $67,153,566 AS OF 3/31/07 Undistributed tax-exempt income $1,462,420 Capital loss carryforwards (3,323,431) Other temporary differences (1,144,959) Net unrealized appreciation (depreciation) 18,185,736 The aggregate cost above includes prior fiscal year end tax adjustments. MULTIPLE CLASSES OF SHARES OF BENEFICIAL INTEREST - The fund offers multiple classes of shares, which differ in their respective distribution and service fees. All shareholders bear the common expenses of the fund based on the value of settled shares outstanding of each class, without distinction between share classes. Dividends are declared separately for each class. Differences in per share dividend rates are generally due to differences in separate class expenses. Class B and Class B1 shares will convert to Class A and Class A1 shares, respectively approximately eight years after purchase. (3) TRANSACTIONS WITH AFFILIATES INVESTMENT ADVISER - The fund has an investment advisory agreement with Massachusetts Financial Services Company (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 0.55% of the fund's average daily net assets. As part of a settlement agreement with the New York Attorney General concerning market timing and related matters, MFS has agreed to reduce the management fee to 0.30% of the fund's average daily net assets for the period March 1, 2004 through February 28, 2009. For the six months ended September 30, 2007, this waiver amounted to $1,048,187 and is reflected as a reduction of total expenses in the Statement of Operations. The management fee incurred for the six months ended September 30, 2007 was equivalent to an annual effective rate of 0.30% of the fund's average daily net assets. The investment adviser has agreed in writing to pay a portion of the fund's operating expenses, exclusive of certain other fees and expenses, such that total annual fund operating expenses do not exceed the following rates annually of the fund's average daily net assets with respect to each class: CLASS A CLASS B CLASS C CLASS A1 CLASS B1 0.74% 1.49% 1.49% 0.49% 1.25% This written agreement will continue through July 31, 2008 unless changed or rescinded by the fund's Board of Trustees. For the six months ended September 30, 2007, the fund's actual operating expenses did not exceed the limit and therefore, the investment advisor did not pay any portion of the fund's expenses. DISTRIBUTOR - MFS Fund Distributors, Inc. (MFD), a wholly-owned subsidiary of MFS, as distributor, received $34,145 for the six months ended September 30, 2007, as its portion of the initial sales charge on sales of Class A and Class A1 shares of the fund. The Board of Trustees has adopted a distribution plan for certain class shares pursuant to Rule 12b-1 of the Investment Company Act of 1940. The fund's distribution plan provides that the fund will pay MFD for services provided by MFD and financial intermediaries in connection with the distribution and servicing of certain share classes. One component of the plan is a distribution fee paid to MFD and another component of the plan is a service fee paid to MFD. MFD may subsequently pay all, or a portion, of the distribution and/or service fees to financial intermediaries.

(e) The annual effective rates represent actual fees incurred under the distribution plan for the six months ended September 30, 2007 based on each class' average daily net assets. For one year from the date of sale of Class B1 shares, assets attributable to such Class B1 shares are subject to the 0.25% annual Class B1 service fee. On assets attributable to all other Class B1 shares, the service fee is not currently in effect, but may be implemented on such date as the fund's Board of Trustees may determine. Payment of the 0.10% annual Class A distribution fee is not yet in effect and will be implemented on such date as the fund's Board of Trustees may determine. Certain Class A, Class A1, and Class C shares are subject to a contingent deferred sales charge in the event of a shareholder redemption within 12 months of purchase. Class B and Class B1 shares are subject to a contingent deferred sales charge in the event of a shareholder redemption within six years of purchase. All contingent deferred sales charges are paid to MFD and during the six months ended September 30, 2007, were as follows: AMOUNT Class A $4,919 Class B $19,967 Class C $3,172 Class A1 -- Class B1 $13,859 SHAREHOLDER SERVICING AGENT - MFS Service Center, Inc. (MFSC), a wholly-owned subsidiary of MFS, receives a fee from the fund for its services as shareholder servicing agent calculated as a percentage of the average daily net assets of the fund as determined periodically under the supervision of the fund's Board of Trustees. For the six months ended September 30, 2007, the fee was $179,386, which equated to 0.0429% annually of the fund's average daily net assets. MFSC also receives payment from the fund for out-of-pocket expenses, sub-accounting and other shareholder servicing costs which may be paid to affiliated and unaffiliated service providers. For the six months ended September 30, 2007, these out-of-pocket expenses, sub-accounting and other shareholder servicing costs amounted to $94,507. The fund may also pay shareholder servicing related costs directly to non-related parties. ADMINISTRATOR - MFS provides certain financial, legal, shareholder communications, compliance, and other administrative services to the fund. Under an administrative services agreement, the fund partially reimburses MFS the costs incurred to provide these services. The fund is charged a fixed amount plus a fee based on average daily net assets. The fund's annual fixed amount is $17,500. The administrative services fee incurred for the six months ended September 30, 2007 was equivalent to an annual effective rate of 0.0173% of the fund's average daily net assets. 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. 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 for their services to the fund from MFS. Certain officers and trustees of the fund are officers or directors of MFS, MFD, and MFSC. The fund has an unfunded, defined benefit plan for certain retired independent trustees which resulted in a pension expense of $2,709. This amount is included in independent trustees' compensation for the six months ended September 30, 2007. The liability for deferred retirement benefits payable to certain retired independent trustees amounted to $81,204 at September 30, 2007, and is included in payable for independent trustees' compensation. OTHER - This fund and certain other MFS funds (the funds) have entered into a services agreement (the Agreement) which provides for payment of fees by the funds to Tarantino LLC in return for the provision of services of an Independent Chief Compliance Officer (ICCO) for the funds. The ICCO is an officer of the funds and the sole member of Tarantino LLC. The funds can terminate the Agreement with Tarantino LLC at any time under the terms of the Agreement. For the six months ended September 30, 2007, the fee paid to Tarantino LLC was $1,961. MFS has agreed to reimburse the fund for a portion of the payments made by the funds to Tarantino LLC in the amount of $1,929, which is shown as a reduction of total expenses in the Statement of Operations. Additionally, MFS has agreed to bear all expenses associated with office space, other administrative support, and supplies provided to the ICCO. (4) PORTFOLIO SECURITIES Purchases and sales of investments, other than U.S. government securities, purchased option transactions, and short-term obligations, aggregated $128,928,863 and $158,114,950, 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.

(6) LINE OF CREDIT The fund and other funds managed by MFS participate in a $1 billion unsecured committed line of credit provided by a syndication of banks under a credit agreement. In addition, the fund and other funds managed by MFS have established uncommitted borrowing arrangements with certain banks. 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 Federal Reserve funds rate plus 0.30%. In addition, a commitment fee, based on the average daily, unused portion of the committed line of credit, is allocated among the participating funds at the end of each calendar quarter. For the six months ended September 30, 2007, the fund's commitment fee and interest expense on the line of credit were $702 and $0, respectively, and are included in miscellaneous expense and interest expense and fees, respectively, on the Statement of Operations. (7) ACQUISITIONS At close of business on June 22, 2007, the fund acquired all of the assets and liabilities of MFS Municipal Bond Fund. In connection with the acquisition, the fund also issued new share Classes A1 and B1 to the acquired fund shareholders, that differ from existing share Classes A and B in respect to class level expenses. The acquisition was accomplished by a tax-free exchange of 117,943,444 shares of the fund (valued at $989,901,585) for all of the assets and liabilities of MFS Municipal Bond Fund. MFS Municipal Bond Fund then converted all of its outstanding shares for the shares of the fund and distributed those shares to its shareholders. MFS Municipal Bond Fund's net assets on that date were $989,901,585, including $45,804,567 of unrealized appreciation, $114,563 of accumulated net investment loss, and $380,444 of accumulated net realized loss on investments. These assets were combined with those of the fund. The aggregate net assets of the fund after the acquisition were $1,291,597,453. BOARD REVIEW OF INVESTMENT ADVISORY AGREEMENT The Investment Company Act of 1940 requires that both the full Board of Trustees and a majority of the non-interested ("independent") Trustees, voting separately, annually approve the continuation of the Fund's investment advisory agreement with MFS. The Trustees consider matters bearing on the Fund and its advisory arrangements at their meetings throughout the year, including a review of performance data at each regular meeting. In addition, the independent Trustees met several times over the course of three months beginning in May and ending in July, 2007 ("contract review meetings") for the specific purpose of considering whether to approve the continuation of the investment advisory agreement for the Fund and the other investment companies that the Board oversees (the "MFS Funds"). The independent Trustees were assisted in their evaluation of the Fund's investment advisory agreement by independent legal counsel, from whom they received separate legal advice and with whom they met separately from MFS during various contract review meetings. The independent Trustees were also assisted in this process by the MFS Funds' Independent Chief Compliance Officer, a full-time senior officer appointed by and reporting to the independent Trustees. In connection with their deliberations regarding the continuation of the investment advisory agreement, the Trustees, including the independent Trustees, considered such information and factors as they believed, in light of the legal advice furnished to them and their own business judgment, to be relevant. The investment advisory agreement for the Fund was considered separately, although the Trustees also took into account the common interests of all MFS Funds in their review. As described below, the Trustees considered the nature, quality, and extent of the various investment advisory, administrative, and shareholder services performed by MFS under the existing investment advisory agreement and other arrangements with the Fund. In connection with their contract review meetings, the Trustees received and relied upon materials that included, among other items: (i) information provided by Lipper Inc. on the investment performance of the Fund for various time periods ended December 31, 2006 and the investment performance of a group of funds with substantially similar investment classifications/objectives (the "Lipper performance universe"), as well as the investment performance of a group of funds identified by objective criteria suggested by MFS ("MFS peer funds"), (ii) information provided by Lipper Inc. on the Fund's advisory fees and other expenses and the advisory fees and other expenses of comparable funds identified by Lipper (the "Lipper expense group"), as well as the advisory fees and other expenses of MFS peer funds, (iii) information provided by MFS on the advisory fees of comparable portfolios of other clients of MFS, including institutional separate accounts and other clients, (iv) information as to whether and to what extent applicable expense waivers, reimbursements or fee "breakpoints" are observed for the Fund, (v) information regarding MFS' financial results and financial condition, including MFS' and certain of its affiliates' estimated profitability from services performed for the Fund and the MFS Funds as a whole, (vi) MFS' views regarding the outlook for the mutual fund industry and the strategic business plans of MFS, (vii) descriptions of various functions performed by MFS for the Funds, such as compliance monitoring and portfolio trading practices, and (viii) information regarding the overall organization of MFS, including information about MFS' senior management and other personnel providing investment advisory, administrative and other services to the Fund and the other MFS Funds. The comparative performance, fee and expense information prepared and provided by Lipper Inc. was not independently verified and the independent Trustees did not independently verify any information provided to them by MFS. The Trustees' conclusion as to the continuation of the investment advisory agreement was based on a comprehensive consideration of all information provided to the Trustees and not the result of any single factor. Some of the factors that figured particularly in the Trustees' deliberations are described below, although individual Trustees may have evaluated the information presented differently from one another, giving different weights to various factors. It is also important to recognize that the fee arrangements for the Fund and other MFS Funds are the result of years of review and discussion between the independent Trustees and MFS, that certain aspects of such arrangements may receive greater scrutiny in some years than in others, and that the Trustees' conclusions may be based, in part, on their consideration of these same arrangements during the course of the year and in prior years. Based on information provided by Lipper Inc. and MFS, the Trustees reviewed the Fund's total return investment performance as well as the performance of peer groups of funds over various time periods. The Trustees placed particular emphasis on the total return performance of the Fund's Class A shares in comparison to the performance of funds in its Lipper performance universe over the three-year period ended December 31, 2006, which the Trustees believed was a long enough period to reflect differing market conditions. The total return performance of the Fund's Class A shares was in the 1st quintile relative to the other funds in the universe for this three-year period (the 1st quintile being the best performers and the 5th quintile being the worst performers). The total return performance of the Fund's Class A shares was in the 2nd quintile for the one-year period and the 1st quintile for the five-year period ended December 31, 2006 relative to the Lipper performance universe. Because of the passage of time, these performance results may differ from the performance results for more recent periods, including those shown elsewhere in this report. In the course of their deliberations, the Trustees took into account information provided by MFS in connection with the contract review meetings, as well as during investment review meetings conducted with portfolio management personnel during the course of the year regarding the Fund's performance. After reviewing these and related factors, the Trustees concluded, within the context of their overall conclusions regarding the investment advisory agreement, that they were satisfied with MFS' responses and efforts relating to investment performance. In assessing the reasonableness of the Fund's advisory fee, the Trustees considered, among other information, the Fund's advisory fee and the total expense ratio of the Fund's Class A shares as a percentage of average daily net assets and the advisory fee and total expense ratios of peer groups of funds based on information provided by Lipper Inc. and MFS. The Trustees considered that there is an advisory fee reduction in effect for the Fund through February 28, 2009 as part of MFS' settlement with the New York Attorney General concerning market timing and related matters. The Trustees also considered that, according to the Lipper data (which takes into account the advisory fee reduction), the Fund's effective advisory fee rate and total expense ratio were each lower than the Lipper expense group median. The Trustees also considered the advisory fees charged by MFS to institutional accounts. In comparing these fees, the Trustees considered information provided by MFS as to the generally broader scope of services provided by MFS to the Fund in comparison to institutional accounts, the higher demands placed on MFS' investment personnel and trading infrastructure as a result of the daily cash in-flows and out-flows of the Fund, and the impact on MFS and expenses associated with the more extensive regulatory regime to which the Fund is subject in comparison to institutional accounts. The Trustees also considered whether the Fund is likely to benefit from any economies of scale in the management of the Fund in the event of growth in assets of the Fund. They noted that the Fund's advisory fee rate schedule is not currently subject to any breakpoints. Taking into account the advisory fee reduction noted above, the Trustees determined not to recommend any advisory fee breakpoints for the Fund at this time. The Trustees also considered information prepared by MFS relating to MFS' costs and profits with respect to the Fund, the MFS Funds considered as a group, and other investment companies and accounts advised by MFS, as well as MFS' methodologies used to determine and allocate its costs to the MFS Funds, the Fund and other accounts and products for purposes of estimating profitability. After reviewing these and other factors described herein, the Trustees concluded, within the context of their overall conclusions regarding the investment advisory agreement, that the advisory fees charged to the Fund represent reasonable compensation in light of the services being provided by MFS to the Fund. In addition, the Trustees considered MFS' resources and related efforts to continue to retain, attract and motivate capable personnel to serve the Fund. The Trustees also considered current and developing conditions in the financial services industry, including the entry into the industry of large and well-capitalized companies which are spending, and appear to be prepared to continue to spend, substantial sums to engage personnel and to provide services to competing investment companies. In this regard, the Trustees also considered the financial resources of MFS and its ultimate parent, Sun Life Financial Inc. The Trustees also considered the advantages and possible disadvantages to the Fund of having an adviser that also serves other investment companies as well as other accounts. The Trustees also considered the nature, quality, cost, and extent of administrative, transfer agency, and distribution services provided to the Fund by MFS and its affiliates under agreements and plans other than the investment advisory agreement, including any 12b-1 fees the Fund pays to MFS Fund Distributors, Inc., an affiliate of MFS. The Trustees also considered the nature, extent and quality of certain other services MFS performs or arranges for on the Fund's behalf, which may include securities lending programs, directed expense payment programs, class action recovery programs, and MFS' interaction with third-party service providers, principally custodians and sub-custodians. The Trustees concluded that the various non-advisory services provided by MFS and its affiliates on behalf of the Funds were satisfactory. The Trustees also considered benefits to MFS from the use of the Fund's portfolio brokerage commissions, if applicable, to pay for investment research (excluding third-party research, for which MFS pays directly) and various other factors. Additionally, the Trustees considered so-called "fall-out benefits" to MFS such as reputational value derived from serving as investment manager to the Fund. Based on their evaluation of factors that they deemed to be material, including those factors described above, the Board of Trustees, including a majority of the independent Trustees, concluded that the Fund's investment advisory agreement with MFS should be continued for an additional one-year period, commencing August 1, 2007. A discussion regarding the Board's most recent review and renewal of the Fund's investment advisory agreement will be available on or before November 1, 2007 by clicking on the fund's name under "Select a fund" on the MFS Web site (mfs.com).
