LETTER FROM THE CEO

[Photo of Robert J. 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

              ----------------------------------------------

(a) The average credit quality of rated securities is based upon a market
    weighted average of portfolio holdings that are rated by public rating
    agencies.
(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.

              ----------------------------------------------

(a) The average credit quality of rated securities is based upon a market
    weighted average of portfolio holdings that are rated by public rating
    agencies.
(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 & 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.

(h) 5% class return per year before expenses.
(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.

(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

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.

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:

MULTIPLE CLASSES OF SHARES OF BENEFICIAL INTEREST - Each fund offers multiple
classes of shares, which differ in their respective distribution and service
fees. 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 Statements 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 each fund's average daily
net assets.

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 the funds.

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.

Each 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.

(6) LINE OF CREDIT

Each 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, 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.

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 each Fund's investment
advisory agreement with MFS. 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.

Fund's Class A shares was in the 3rd quintile for the one-year period and the
2nd 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.

Fund's Class A shares was in the 3rd quintile for the one-year period and the
2nd quintile for the five-year period ended December 31, 2006 relative to the

LETTER FROM THE CEO

[Photo of Robert J. 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

(a) The average credit quality of rated securities is based upon a market
    weighted average of portfolio holdings that are rated by public rating
    agencies.
(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.

              Average Credit Quality of
              Rated Securities (short-term) (a)          A-1
              ----------------------------------------------

(a) The average credit quality of rated securities is based upon a market
    weighted average of portfolio holdings that are rated by public rating
    agencies.
(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.

    year. Expenses paid do not include any applicable sales charges (loads). If
    these transaction costs had been included, your costs would have been
    higher.

The financial highlights table is intended to help you understand the fund's financial performance for the semiannual period and
the past 5 fiscal years. Certain information reflects financial results for a single fund share. The total returns in the table
represent the rate by which an investor would have earned (or lost) on an investment in the fund share class (assuming
reinvestment of all distributions) held for the entire period.

the past 5 fiscal years. Certain information reflects financial results for a single fund share. The total returns in the table
represent the rate by which an investor would have earned (or lost) on an investment in the fund share class (assuming
reinvestment of all distributions) held for the entire period.

(1) BUSINESS AND ORGANIZATION

MFS Mississippi Municipal Bond Fund (Mississippi Fund), MFS New York Municipal
Bond Fund (New York Fund), MFS North Carolina Municipal Bond Fund (North
Carolina Fund), MFS Pennsylvania Municipal Bond Fund (Pennsylvania Fund), MFS
South Carolina Municipal Bond Fund (South Carolina Fund), MFS Tennessee
Municipal Bond Fund (Tennessee Fund), MFS Virginia Municipal Bond Fund
(Virginia Fund), and MFS West Virginia Municipal Bond Fund (West Virginia 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 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:

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:

MULTIPLE CLASSES OF SHARES OF BENEFICIAL INTEREST - Each fund offers multiple classes of shares, which differ in their respective
distribution and service fees. 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.

The management fee incurred for the six months ended September 30, 2007 was equivalent to an annual effective rate of 0.30% of each
fund's average daily net assets.

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.

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.

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.

(6) LINE OF CREDIT

Each 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, 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.

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 each Fund's investment
advisory agreement with MFS. 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). The total return performance of the
Fund's Class A shares was in the 2nd quintile for each of the one- and five-

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 agreements, that
they were satisfied with MFS' responses and efforts relating to investment
performance.

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.

LETTER FROM THE CEO

[Photo of Robert J. 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

              -----------------------------------------------

(a) The average credit quality of rated securities is based upon a market
    weighted average of portfolio holdings that are rated by public rating
    agencies.
(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.

(h) 5% class return per year before expenses.
(i) For the period of the class' inception, June 25, 2007 through the stated

(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.

FINANCIAL HIGHLIGHTS

The financial highlights table is intended to help you understand the fund's financial performance for the semiannual period
and the past 5 fiscal years (or life of a particular share class, if shorter). Certain information reflects financial results
for a single fund share. The total returns in the table represent the rate by which an investor would have earned (or lost) on
an investment in the fund share class (assuming reinvestment of all distributions) held for the entire period.

(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

          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.

(d) In accordance with the distribution plan for certain classes, the fund pays distribution and/or service fees up
    to these annual percentage rates of each class' average daily net assets.
(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

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.

(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).
