LETTER FROM THE CEO

[Photo of Robert J. Manning]

Dear Shareholders:

    What a difference a year can make. By the end of 2005, the Dow Jones
Industrial Average had lost value over the course of the year, as stocks were
beaten back by a myriad of investor worries, including a spike in oil prices, a
rise in interest rates, and political uncertainty in the Middle East.

    Fast forward to 2006, and we have seen a dramatically different picture.
While there were some fluctuations in the global markets in the first half of
the year, the second half of 2006 has, so far, been good to many investors. Oil
prices retreated, boosting consumer confidence, and interest rates have held
steady. U.S. stock markets responded favorably to this news, as the Dow reached
a record high in October, passing the 12,000 mark.

    What does all of this mean for you? If you're focused on a long-term
investment strategy, the high points in the road -- and the bumps -- should not
necessarily dictate portfolio action on your part. Markets are inherently
cyclical, and we firmly believe that investors who remain committed to a long-
term investment strategy are more likely to achieve their goals than those who
consistently chase short-term performance.

    At MFS(R), our unique teamwork approach to managing money and our global
research platform support an unwavering focus on helping you realize your
long-term financial goals. We believe in a three-pronged investment strategy of
allocating your holdings across major asset classes, diversifying within each
class, and rebalancing regularly. 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 are essential to capitalizing
on the many opportunities the financial markets can offer.

    Respectfully,

/s/ Robert J. Manning

    Chief Executive Officer and Chief Investment Officer

(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 graphical presentation, the bond component includes
    both accrued interest amounts and the equivalent expo sure 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 accou nt 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 b y 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 th ose portfolios that hold a
    security which is not rated by any of the three agencies, the security is
    considered Not Rated. Holding s in U.S. Treasuries and government agency
    mortgage-backed securities, if any, are included in the "AAA"-rating
    category. Percentages ar e based on the total market value of investments as
    of 09/30/06.

Percentages are based on net assets as of 09/30/06, unless otherwise noted.

The portfolios are actively managed and current holdings may be different.


EXPENSE TABLES

FUND EXPENSES BORNE BY THE SHAREHOLDERS DURING THE PERIOD, APRIL 1, 2006,
THROUGH SEPTEMBER 30, 2006.

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 redemption fees on certain exchanges and redemptions, 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, 2006 through September 30,
2006.

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 each 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) or redemption fees. 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.

(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) or
    redemption fees. If these transaction costs had been included, your costs
    would have been higher.

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 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 (the trust). The trust 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 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. Values of debt
instruments 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. 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 a broker-dealer bid quotation. 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. 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 each fund's valuation policies and procedures, market
quotations are not considered to be readily available for many types of debt
instruments. These investments are generally valued at fair value based on
information from independent pricing services. 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 on 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 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 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.

INTEREST RATE SWAP AGREEMENTS - Interest rate swap agreements 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 fluctuations.

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 and 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 involving its
portfolio holdings. Any proceeds received are reflected in realized gain/loss in
the Statement of Operations, or in unrealized gain/loss if the security is still
held by the fund.

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, 2006, is shown as a
reduction of total expenses on the Statement 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 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 expiration of capital loss
carryforwards, amortization and accretion of debt securities, defaulted bonds,
and treating a portion of the proceeds from redemptions as a distribution for
tax purposes.

The tax character of distributions made during the current period will be
determined at fiscal year end. The tax character of distributions declared to
shareholders is as follows:

In June 2006, FASB Interpretation No. 48, Accounting for Uncertainty in Income
Taxes (the "Interpretation") was issued, and is effective for fiscal years
beginning after December 15, 2006 and is to be applied to all open tax years as
of the effective date. This Interpretation prescribes a minimum threshold for
financial statement recognition of the benefit of a tax position taken or
expected to be taken in a tax return, and requires certain expanded disclosures.
Management is evaluating the application of the Interpretation to each fund, and
has not at this time determined the impact, if any, resulting from the adoption
of this Interpretation on each fund's financial statements.

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 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 shares will convert to Class A shares approximately eight
years after purchase.

(3) TRANSACTIONS WITH AFFILIATES

INVESTMENT ADVISER - The trust 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, 2006, this
waiver amounted to the following for each fund and is reflected as a reduction
of total expenses in the Statement of Operations.

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, 2006, 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 affiliated funds 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 affiliated funds have established uncommitted borrowing
arrangements with certain brokers. 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 0.35%. 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. The interest expense incurred and commitment fee allocated to each fund for the six months ended
September 30, 2006 is included in miscellaneous expense on the Statement of Operations as follows:

(7) CONCENTRATION OF CREDIT RISK

Since each fund invests a substantial portion of its assets in issuers located in one state, it will be more susceptible to
factors adversely affecting issuers of that state than would be a comparable tax-exempt mutual fund that invests nationally. The
risk associated with such factors is mitigated by the fact that a percentage of securities in a portfolio of investments are
backed by letters of credit or bond insurance of various financial institutions and financial guaranty assurance agencies. At
September 30, 2006, the percentage of holdings that carried such enhancements were as follows:


                      ALABAMA      ARKANSAS      CALIFORNIA      FLORIDA      GEORGIA      MARYLAND      MASSACHUSETTS
                         FUND          FUND            FUND         FUND         FUND          FUND               FUND
                                                                                           
Total:                 69.93%        74.18%          49.28%       61.51%       50.04%        30.21%             47.10%

For each fund, the greatest exposure to any one institution or agency did not exceed the following percentages of total
investments as of September 30, 2006:


                      ALABAMA      ARKANSAS      CALIFORNIA      FLORIDA      GEORGIA      MARYLAND      MASSACHUSETTS

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, 2006 ("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 which included, among other items: (i) information
provided by Lipper Inc. on the investment performance of the Funds for various
time periods ended December 31, 2005 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 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 Lipper performance universe over
the three-year period ended December 31, 2005, which the Trustees believed was a
long enough period to reflect differing market conditions.

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 Funds' 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.

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 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's 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, 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 which 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, 2006.

LETTER FROM THE CEO

Dear Shareholders:

    What a difference a year can make. By the end of 2005, the Dow Jones
Industrial Average had lost value over the course of the year, as stocks were
beaten back by a myriad of investor worries, including a spike in oil prices, a
rise in interest rates, and political uncertainty in the Middle East.

    Fast forward to 2006, and we have seen a dramatically different picture.
While there were some fluctuations in the global markets in the first half of
the year, the second half of 2006 has, so far, been good to many investors. Oil
prices retreated, boosting consumer confidence, and interest rates have held
steady. U.S. stock markets responded favorably to this news, as the Dow reached
a record high in October, passing the 12,000 mark.

    What does all of this mean for you? If you're focused on a long-term
investment strategy, the high points in the road -- and the bumps -- should not
necessarily dictate portfolio action on your part. Markets are inherently
cyclical, and we firmly believe that investors who remain committed to a long-
term investment strategy are more likely to achieve their goals than those who
consistently chase short-term performance.

    At MFS(R), our unique teamwork approach to managing money and our global
research platform support an unwavering focus on helping you realize your
long-term financial goals. We believe in a three-pronged investment strategy
of allocating your holdings across major asset classes, diversifying within
each class, and rebalancing regularly. 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 are essential to
capitalizing on the many opportunities the financial markets can offer.

    Respectfully,

/s/ Robert J. Manning

    Robert J. Manning
    Chief Executive Officer and Chief Investment Officer
    MFS Investment Management(R)

    November 15, 2006

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

(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 graphical presentation, the bond component includes
    both accrued interest amounts and the equivalent expo sure 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 09/30/06.

Percentages are based on net assets as of 09/30/06, unless otherwise noted.

The portfolios are actively managed and current holdings may be different.

EXPENSE TABLES

FUND EXPENSES BORNE BY THE SHAREHOLDERS DURING THE PERIOD, APRIL 1, 2006,
THROUGH SEPTEMBER 30, 2006.

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 redemption fees on certain exchanges and redemptions, 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, 2006 through September
30, 2006.

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 each 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) or redemption fees. 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.

(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 (the trust). The trust 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 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. Values of debt
instruments 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. 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 a broker-dealer bid quotation. 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. 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 each fund's valuation policies and procedures, market
quotations are not considered to be readily available for many types of debt
instruments. These investments are generally valued at fair value based on
information from independent pricing services. 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 on 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 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.

INTEREST RATE SWAP AGREEMENTS - Interest rate swap agreements 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 fluctuations.

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 the 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 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.

Each fund may receive proceeds from litigation settlements involving its
portfolio holdings. Any proceeds received are reflected in realized gain/loss in
the Statement of Operations, or in unrealized gain/loss if the security is still
held by the fund.

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, 2006, is shown as a
reduction of total expenses on the Statement 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 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, wash sale loss deferrals, and treating a portion of the proceeds
from redemptions as a distribution for tax purposes.

The tax character of distributions made during the current period will be
determined at fiscal year end. The tax character of distributions declared to
shareholders is as follows:

In June 2006, FASB Interpretation No. 48, Accounting for Uncertainty in Income
Taxes (the "Interpretation") was issued, and is effective for fiscal years
beginning after December 15, 2006 and is to be applied to all open tax years as
of the effective date. This Interpretation prescribes a minimum threshold for
financial statement recognition of the benefit of a tax position taken or
expected to be taken in a tax return, and requires certain expanded disclosures.
Management is evaluating the application of the Interpretation to each fund, and
has not at this time determined the impact, if any, resulting from the adoption
of this Interpretation on each fund's financial statements.

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 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 shares will convert to Class A shares approximately eight
years after purchase.

(3) TRANSACTIONS WITH AFFILIATES

INVESTMENT ADVISER - The trust 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, 2006, 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, 2006 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 fund's 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, 2007 unless changed or
rescinded by the fund's Board of Trustees. For the six months ended September
30, 2006, this reduction amounted to $61,216 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, 2006, as its portion of the initial sales charge on sales of Class

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 affiliated funds 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 affiliated funds 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 0.35%. 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. The interest expense incurred and commitment fee allocated to each fund for the six
months ended September 30, 2006 is included in miscellaneous expense on the Statement of Operations as follows:


                                                      NORTH                       SOUTH                                      WEST

(7) CONCENTRATION OF CREDIT RISK

Since each fund invests a substantial portion of its assets in issuers located in one state, it will be more susceptible to
factors adversely affecting issuers of that state than would be a comparable tax-exempt mutual fund that invests nationally.
The risk associated with such factors is mitigated by the fact that a percentage of securities in a portfolio of investments
are backed by letters of credit or bond insurance of various financial institutions and financial guaranty assurance
agencies. At September 30, 2006, the percentage of holdings that carried such enhancements were as follows:


                                                      NORTH                       SOUTH                                      WEST
                  MISSISSIPPI        NEW YORK      CAROLINA  PENNSYLVANIA      CAROLINA     TENNESSEE      VIRGINIA      VIRGINIA
                         FUND            FUND          FUND          FUND          FUND          FUND          FUND          FUND
                                                                                                   
Total:                 79.41%          40.14%        50.44%        67.28%        72.88%        55.91%        41.04%        79.89%

For each fund, the greatest exposure to any one institution or agency did not exceed the following percentages of total
investments as of September 30, 2006:


                                                      NORTH                       SOUTH                                      WEST

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, 2006 ("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 which included, among other items: (i) information
provided by Lipper Inc. on the investment performance of the Funds for various
time periods ended December 31, 2005 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
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 Lipper performance universe over
the three-year period ended December 31, 2005, which the Trustees believed was
a long enough period to reflect differing market conditions.

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 Funds'
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.

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 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's 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 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 which 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, 2006.

MFS MISSISSIPPI MUNICIPAL BOND FUND

The Fund's Class A performance was in the 2nd quintile relative to the other
funds in the universe for the three-year period ended December 31, 2005 (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 1st quintile for each of the one and five-year periods ended December 31,
2005 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 assessing the reasonableness of the Fund's advisory fee, the Trustees also
considered that, according to the Lipper data, the Fund's effective advisory
fee rate (taking into account the advisory fee reduction) and total expense
ratio were each lower than the Lipper expense group median.

MFS NEW YORK MUNICIPAL BOND FUND

The Fund's Class A performance was in the 3rd quintile relative to the other
funds in the universe for the three-year period ended December 31, 2005 (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,
2005 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 assessing the reasonableness of the Fund's advisory fee, the Trustees also
considered that, according to the Lipper data, the Fund's effective advisory
fee rate (taking into account the advisory fee reduction) was lower than the
Lipper expense group median, and the Fund's total expense ratio was
approximately at the Lipper expense group median.

MFS NORTH CAROLINA MUNICIPAL BOND FUND

The Fund's Class A performance was in the 2nd quintile relative to the other
funds in the universe for the three-year period ended December 31, 2005 (the

performers). The total return performance of the Fund's Class A shares was in
the 1st quintile for the one-year period and the 2nd quintile for the five-
year period ended December 31, 2005 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 assessing the reasonableness of the Fund's advisory fee, the Trustees also
considered that, according to the Lipper data, the Fund's effective advisory
fee rate (taking into account the advisory fee reduction) was lower than the
Lipper expense group median, and the Fund's total expense ratio was
approximately at the Lipper expense group median.

MFS PENNSYLVANIA MUNICIPAL BOND FUND

The Fund's Class A performance was in the 2nd quintile relative to the other
funds in the universe for the three-year period ended December 31, 2005 (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 1st quintile for each of the one- and five-year periods ended December 31,
2005 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 assessing the reasonableness of the Fund's advisory fee, the Trustees
considered, the advisory fee reduction noted above and that MFS currently
observes an expense limitation for the Fund. The Trustees also considered
that, according to the Lipper data, the Fund's effective advisory fee rate
(taking into account advisory fee reduction and the expense limitation) and
total expense ratio were each lower than the Lipper expense group median.

MFS SOUTH CAROLINA MUNICIPAL BOND FUND

The Fund's Class A performance was in the 2nd quintile relative to the other
funds in the universe for the three-year period ended December 31, 2005 (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 1st quintile for the one-year period and the 2nd quintile for the five-
year period ended December 31, 2005 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 assessing the reasonableness of the Fund's advisory fee, the Trustees also
considered that, according to the Lipper data, the Fund's effective advisory
fee rate (taking into account the advisory fee reduction) was lower than the

The Fund's Class A performance was in the 3rd quintile relative to the other
funds in the universe for the three-year period ended December 31, 2005 (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 1st quintile for the one-year period and the 2nd quintile for the five-
year period ended December 31, 2005 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 assessing the reasonableness of the Fund's advisory fee, the Trustees also
considered that, according to the Lipper data, the Fund's effective advisory
fee rate (taking into account the advisory fee reduction) was lower than the
Lipper expense group median, and the Fund's total expense ratio was
approximately at the Lipper expense group median.

MFS VIRGINIA MUNICIPAL BOND FUND

funds in the universe for the three-year period ended December 31, 2005 (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,
2005 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 assessing the reasonableness of the Fund's advisory fee, the Trustees also
considered that, according to the Lipper data, the Fund's effective advisory
fee rate (taking into account the advisory fee reduction) was lower than the

Lipper expense group median.

MFS WEST VIRGINIA MUNICIPAL BOND FUND

funds in the universe for the three-year period ended December 31, 2005 (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,
2005 relative to the Lipper performance universe. Because of the passage of

LETTER FROM THE CEO

Dear Shareholders:

    What a difference a year can make. By the end of 2005, the Dow Jones
Industrial Average had lost value over the course of the year, as stocks were
beaten back by a myriad of investor worries, including a spike in oil prices,
a rise in interest rates, and political uncertainty in the Middle East.

    Fast forward to 2006, and we have seen a dramatically different picture.
While there were some fluctuations in the global markets in the first half of
the year, the second half of 2006 has, so far, been good to many investors.
Oil prices retreated, boosting consumer confidence, and interest rates have
held steady. U.S. stock markets responded favorably to this news, as the Dow
reached a record high in October, passing the 12,000 mark.

    What does all of this mean for you? If you're focused on a long-term
investment strategy, the high points in the road -- and the bumps -- should
not necessarily dictate portfolio action on your part. Markets are inherently
cyclical, and we firmly believe that investors who remain committed to a long-
term investment strategy are more likely to achieve their goals than those who
consistently chase short-term performance.

    At MFS(R), our unique teamwork approach to managing money and our global
research platform support an unwavering focus on helping you realize your
long-term financial goals. We believe in a three-pronged investment strategy
of allocating your holdings across major asset classes, diversifying within
each class, and rebalancing regularly. 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 are essential to
capitalizing on the many opportunities the financial markets can offer.

    Respectfully,

/s/ Robert J. Manning

    Robert J. Manning
    Chief Executive Officer and Chief Investment Officer
    MFS Investment Management(R)

    November 15, 2006

- -------------------------------------------------------
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 graphical 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 9/30/06.

Percentages are based on net assets as of 9/30/06, 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, 2006 through September 30, 2006.

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 redemption fees on certain exchanges and redemptions, 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, 2006 through
September 30, 2006.

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) or redemption fees. 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.
(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) or
    redemption fees. 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.

NOTES TO FINANCIAL STATEMENTS
(unaudited)

(1) BUSINESS AND ORGANIZATION

MFS Municipal Income Fund (the fund) is a series of MFS Municipal Series Trust
(the trust). The trust 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. Values of debt
instruments 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. 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 a broker-dealer bid quotation. 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. 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. These investments are generally valued at fair value based on
information from independent pricing services. 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 on 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.

INTEREST RATE SWAP AGREEMENTS - Interest rate swap agreements 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 fluctuations.

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 involving its portfolio holdings. Any proceeds received are
reflected in realized gain/loss in the Statement of Operations, or in unrealized
gain/loss if the security is still held by the fund. 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, 2006, 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 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.

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:



                                                                              3/31/06             3/31/05

                                                                                            
Ordinary income (including any short-term capital gains)                          $--             $27,254
Tax-exempt income                                                          14,360,201          15,355,366
- ---------------------------------------------------------------------------------------------------------
Total distributions                                                       $14,360,201         $15,382,620
- ---------------------------------------------------------------------------------------------------------


The federal tax cost and the tax basis components of distributable earnings
were as follows:

          AS OF 9/30/06
          Cost of investments                           $286,623,352
          ----------------------------------------------------------
          Gross appreciation                             $24,218,758
          Gross depreciation                              (3,260,053)
          ----------------------------------------------------------
          Net unrealized appreciation (depreciation)     $20,958,705
          ----------------------------------------------------------

          AS OF 3/31/06
          Undistributed tax-exempt income                  1,078,782
          Capital loss carryforwards                      (4,190,232)
          Other temporary differences                       (977,077)
          Net unrealized appreciation (depreciation)      18,244,047

The aggregate cost above includes prior fiscal year end tax adjustments.

As of March 31, 2006, the fund had capital loss carryforwards available to
offset future realized gains. Such losses expire as follows:

          3/31/11                                          $(104,559)
          3/31/12                                         (4,085,673)
          ----------------------------------------------------------
                                                         $(4,190,232)

In June 2006, FASB Interpretation No. 48, Accounting for Uncertainty in Income
Taxes (the "Interpretation") was issued, and is effective for fiscal years
beginning after December 15, 2006 and is to be applied to all open tax years
as of the effective date. This Interpretation prescribes a minimum threshold
for financial statement recognition of the benefit of a tax position taken or
expected to be taken in a tax return, and requires certain expanded
disclosures. Management is evaluating the application of the Interpretation to
the fund's, and has not at this time determined the impact, if any, resulting
from the adoption of this Interpretation on the fund's financial statements.

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 shares will convert to Class A shares 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, 2006, this waiver amounted to $386,511 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, 2006 was
equivalent to an annual effective rate of 0.30% of the fund's average daily
net assets.

DISTRIBUTOR - MFS Fund Distributors, Inc. (MFD), a wholly-owned subsidiary of
MFS, as distributor, received $18,175 for the six months ended
September 30, 2006, as its portion of the initial sales charge on sales of
Class A 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.

    distribution plan for the six months ended September 30, 2006, based on
    each class' average daily net assets. 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 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 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, 2006, were as follows:

                                                          AMOUNT

              Class A                                    $41,281
              Class B                                    $37,211
              Class C                                     $2,497

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 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, 2006, the fee
was $149,038, which equated to 0.0964% annually of the fund's average daily
net assets. MFSC also receives payment from the fund for out-of-pocket and
sub-accounting expenses paid by MFSC on behalf of the fund. For the six months
ended September 30, 2006, these costs amounted to $9,745. The fund may also
pay shareholder servicing related costs 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 calendar year average net assets. From July 1, 2005
through March 31, 2006, the fund's annual fixed amount was $10,000. Effective
April 1, 2006, the fund's annual fixed amount is $17,500.

The administrative services fee incurred for the six months ended
September 30, 2006 was equivalent to an annual effective rate of 0.0212% 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 $1,462. This amount is
included in Independent Trustees' compensation for the six months ended
September 30, 2006. The deferred liability for retirement benefits payable to
certain retired Trustees amounted to $29,676 at September 30, 2006, 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, 2006, the fee paid to
Tarantino LLC was $793. MFS has agreed to reimburse the fund for a portion of
the payments made by the funds to Tarantino LLC in the amount of $792, 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 affiliated funds 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 affiliated funds 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
0.35%. 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, 2006, the fund's commitment fee and interest expense were $943 and $0,
respectively, and are included in miscellaneous expense on the Statement of
Operations.

(7) CONCENTRATION OF CREDIT RISK

At September 30, 2006, 41.5% of securities in the portfolio of investments are
backed by letters of credit or bond insurance of various financial
institutions and financial guaranty assurance agencies. The percentage of
investments insured by or supported (backed) by a letter of credit from any
one institution or agency did not exceed 14.5% of total investments.


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, 2006 ("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 which included, among other items: (i) information
provided by Lipper Inc. on the investment performance of the Fund for various
time periods ended December 31, 2005 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 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, 2005, which the Trustees believed was
a long enough period to reflect differing market conditions. The Fund's
performance 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 1st quintile for each of
the one- and five-year periods ended December 31, 2005 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 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, the Fund's effective advisory
fee rate (taking into account the advisory fee reduction) 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 which 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, 2006.

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, 2006 by clicking on the fund's name under "Select a fund" on the
MFS Web site (mfs.com).
