LETTER FROM THE CHAIRMAN
[Photo of Jeffrey L. Shames]
Jeffrey L. Shames
Dear Shareholders,
This spring, the U.S. stock market experienced record point drops and
volatility that have given many investors cause for concern. While the recent
market correction has rattled a lot of nerves, it's important to put the
current market environment into perspective. Throughout the history of the
market, investors have experienced numerous corrections (declines of more than
20%) and periods of extreme volatility. Of course, past performance is no
guarantee of future results, however, over the long-term, stock and bond
investors have enjoyed returns that have solidly outpaced inflation.
From our perspective, as we look at the global investment climate at the
beginning of the new millennium, we see many reasons for optimism, as well as
the need to voice some words of caution. Our reasons for being optimistic
about both stock and bond markets include:
o STRONG CORPORATE EARNINGS GROWTH: We believe that, over time, the most
important driver of stock prices is corporate earnings. Our research
indicates that the average earnings growth for U.S. companies could approach
15% in 2000, which would bode very well for U.S. equities. We are also
seeing encouraging signs that companies worldwide, and particularly in
Europe, are beginning to focus more on earnings and shareholder value --
that is, delivering stock price performance that will reward investors. As
we research companies around the globe, we are finding that specific areas
of opportunity include technology companies, especially those involved in
wireless telecommunications and in supplying infrastructure and services for
the Internet.
o LOW INFLATION WORLDWIDE: We believe accelerating inflation is one of the
chief factors that could end the current economic boom. While the U.S.
economy continues to grow rapidly, we have not experienced significant signs
of inflation. In our opinion, perhaps the major force keeping inflation at
bay is worldwide productivity increases, fueled by advancing technology. A
technological revolution based on computerization and the Internet appears
to be making it possible for companies to produce more products with less
employees, thereby enabling companies to increase earnings without raising
prices. A related factor keeping inflation down is the heightened
competition of an increasingly global marketplace, where, for example,
businesses are beginning to use computer networks and the Internet to shop
worldwide for the lowest prices from suppliers.
o STRONG GLOBAL ECONOMIES: Our outlook is that a majority of national
economies will continue to experience healthy growth with low inflation. In
late January, the current economic boom in the United States became the
longest in the nation's history. It appears to us that the U.S. Federal
Reserve Board's (the Fed's) program of gradual interest-rate increases will
eventually be successful in cooling the somewhat-overheated U.S. economy
while prolonging the boom. In Europe, we see strong evidence that most
countries will continue on a moderate growth path with low inflation. A
major reason for this is that European companies have begun to adopt the
practices of downsizing, outsourcing, and consolidation that have helped
revitalize U.S. industry over the past decade. We are witnessing a similar
situation in Japan, as more firms merge, restructure, and invest in
technology. In the Pacific Rim, most economies have recovered from the
economic turmoil of late summer 1998 and are surging ahead. We believe
progress toward restructuring Asia's banking systems and other ailing
industries bodes well for stronger investor confidence in the region. While
business conditions have been less favorable in Latin America due to
relatively high inflation, increased exports and industrial production
suggest to us that the region's recession has ended.
Amid this positive global outlook, however, we believe investors should also
heed some cautionary notes:
o IT IS HIGHLY UNLIKELY THAT U.S. EQUITY MARKETS WILL CONTINUE TO PERFORM AT
THE PACE OF THE LAST SEVERAL YEARS. Although our outlook for U.S. markets
this year is quite positive, we believe it is unrealistic for investors to
expect stock market returns, as measured by the Standard & Poor's 500
Composite Index,(1) to routinely exceed 20%, as they did for the past four
years.
o HIGH VALUATIONS, ESPECIALLY OF TECHNOLOGY STOCKS, HAVE MADE U.S. MARKETS
INCREASINGLY VOLATILE. Investor excitement over the past year has pushed
many technology-related stocks to very high relative prices, as expressed by
their price/earnings (P/E) ratios. In general, we believe these higher
valuations are largely supported by the strong earnings growth mentioned
earlier. However, as we've recently experienced, this backdrop has led to a
highly volatile environment, where the market is swift to punish companies
whose earnings are less than expected and where fear can rapidly overcome
the desire to invest for long-term goals.
o RISING INTEREST RATES MAY DAMPEN MARKETS IN THE SHORT TERM, PARTICULARLY IN
THE UNITED STATES AND EUROPE. The Fed's current program of raising interest
rates could potentially cool both stock and bond markets, and the European
Central Bank has tended to follow the lead of the Fed in adjusting its own
interest rates. It is our expectation, however, that in the long term
interest rates will trend down again, perhaps by the end of this year. We
believe that could be favorable for both equity and fixed-income
investments.
On balance, it appears to us that the current global investment climate is
well matched to MFS' research-oriented style of investing. In the equity
markets, where we believe earnings growth is the most reliable indicator of
long-term performance, we feel our research team is second to none in
determining the real value of a company and its long-term earnings potential.
To do that, our portfolio managers and our worldwide team of research analysts
spend extensive time visiting with companies, talking to their customers, and
investigating their competition. In fixed-income investing, we believe the
quality of our research gives us an advantage by helping us determine which
types of securities can add the most value to a fund, and by helping us reduce
the credit risk which is the biggest danger to some higher-income bond funds.
In sum, MFS Original Research(R) is one of the most important factors in our
ongoing effort to deliver competitive performance to you, our investors.
We appreciate your confidence and welcome any questions or comments
you may have.
Respectfully,
/s/ Jeffrey L. Shames

MANAGEMENT REVIEW AND OUTLOOK
[Photo of Geoffrey L. Schechter]
Geoffrey L. Schechter
For the 12 months ended March 31, 2000, Class A shares of the Fund provided a
total return of -1.15%, Class B shares -1.89%, and Class C shares -1.89%. These
returns include the reinvestment of any distributions but exclude the effects of
any sales charges and compare to a -0.08% return over the same period for the
Fund's benchmark, the Lehman Brothers Municipal Bond Index (the Lehman Index),
an unmanaged index of national municipal bond investments rated "Baa" or higher,
and to a -2.40% return for the average general municipal debt fund tracked by
Lipper Inc., an independent firm that reports mutual fund performance.
Q. WHY DID THE MUNICIPAL BOND MARKET AND THE FUND POST NEGATIVE RETURNS DURING
THE 12-MONTH PERIOD?
A. The past 12 months proved difficult for fixed-income investments. Strong
economic growth in the United States, combined with the lowest unemployment
rate in 30 years, rekindled fears of inflation. These concerns, in turn,
resulted in higher interest rates and falling bond prices (interest rates
and bond prices move in opposite directions). Further fueling the rise in
interest rates was a pickup in global economic activity, as foreign
economies recovered from the emerging market crisis of 1998. This backdrop
helped convince the Federal Reserve Board (the Fed) to raise the federal
funds rate -- the rate banks charge each other for overnight loans -- five
times during the past nine months. By doing so, the Fed was trying to
dampen economic growth to a more sustainable level and thereby moderate
inflationary pressures. As a result, yields on 30-year "AAA"-rated general
obligation municipal bonds increased to 5.62% on March 31, 2000, up from
4.97% a year ago.
The municipal market enjoyed a positive first quarter of 2000. Rates on 30-
year "AAA"-rated general obligation municipal bonds peaked at 5.92% in mid-
January before declining by 30 basis points (0.30%). That's because investors
became more confident that Fed actions would indeed curb economic activity
and contain inflation. Another benefit was a dramatic reduction in new-issue
supply thus far in 2000, which was down by more than 40% compared to the same
period in 1999. This decline followed the 25% drop for all of 1999, down from
the near-record levels of new issuance achieved in 1998, when very low
interest rates encouraged municipalities to come to market for new funding.
Q. WHY DID THE FUND'S PERFORMANCE TRAIL THAT OF THE LEHMAN INDEX?
A. There are two reasons. First, the Lehman Index held more shorter-term
municipal bonds in the one- to 12-year maturity range -- about 48% -- than
the Fund, which held about 15% to 20%. We overweighted longer-maturity
bonds in order to capture the higher yields that they offered. However, in
a rising interest-rate environment, longer-maturity bonds are more
sensitive to price declines than shorter-maturity alternatives. Second, the
Lehman Index is of higher average credit quality than the Fund. Lower-rated
bonds underperformed higher-rated bonds as spreads widened during the past
12 months.
Q. THE FUND DID OUTPERFORM ITS LIPPER AVERAGE.
A. Yes, and we're pleased that the Fund's relative performance held up in a
bad market. The Fund benefited from the fact that we kept its duration
slightly shorter than its competitors'. Duration is an indication of a
portfolio's sensitivity to changes in interest rates. With a shorter
duration, the portfolio was less susceptible than its peers to price
declines resulting from increases in interest rates.
Q. WHAT CAN YOU TELL US ABOUT THE AVERAGE CREDIT QUALITY OF THE MUNICIPAL MARKET
AND ITS EFFECT ON THE FUND?
A. Given the continued strength of the U.S. economy and its long-running
expansion, the fiscal health of many municipal issuers has been sustained
or improved, resulting in overall high credit quality in the market. At the
same time we felt that most lower-quality bonds did not offer enough of a
reward for taking on the additional credit risk. Therefore, we spent much
of this past year reducing the Fund's exposure to lower-quality bonds.
Indeed, lower-quality bonds underperformed higher-rated securities during
the 12-month period, so the reduced weighting in lower-rated credits proved
helpful to the Fund's relative performance. Nevertheless, we were able to
selectively add lower-rated bonds to the portfolio when we felt we were
being paid to take on the added risk. In addition, as interest rates moved
higher, we were able to purchase new issues that offered higher yields and
better protection from being called, or redeemed, before maturity if
interest rates were to fall once again.
We believe that active management can add value to fixed-income mutual funds.
Our investment process relies heavily on fundamental analysis and less on
making major interest-rate projections. While we do generally have an outlook
on the direction of interest rates, we tend to adjust the portfolio's
duration only when we have a strong opinion one way or the other. Instead, we
aim to differentiate ourselves with MFS Original Research(R), through which
we implement an issuer-oriented, bottom-up approach to selecting securities
for the portfolio. We have a strong team of research analysts who examine the
fundamental strengths and weaknesses of each issuer. We attempt to overweight
sectors that we believe have positive risk/reward profiles. Our goal is to
provide the highest sustainable income, while managing risk for the benefit
of our shareholders.
Q. WERE YOU ATTRACTED TO ANY PARTICULAR STATES OR REGIONS?
A. While each state offered its own unique types of securities, issuance
patterns, and cash flows, no one region stood out. The U.S. economy on the
whole has performed very well for several years.
Q. WHAT ABOUT SECTORS? WERE THERE SOME THAT WERE PARTICULARLY ATTRACTIVE?
A. We've gravitated toward sectors that we believe have benefited from the
current economic expansion, including general obligation bonds, tax-backed
bonds, and essential-service credits such as water and sewer, port
authorities, and higher education. We believe that their high credit
quality should help provide the portfolio with a reasonable amount of
stability. Another area that we believe offers relative value is the
utilities sector. In that category, our analysts have selectively
recommended issuers that have generated consistent cash flows due to steady
revenue streams and sizable market shares. In some areas, the utilities
sector has been slow to experience the effects of competitive price
pressures predicted to emerge as a result of deregulation, while offering
opportunities because of restructuring that has occurred over the past few
years. At the same time, we've moved very cautiously on health care bonds.
Managed-care competition and concerns about declines in Medicare and
Medicaid reimbursements resulting from the Balanced Budget Act of 1997
have caused significant difficulties in this industry nationwide. Our
reduced exposure to this sector paid off in terms of the portfolio's
relative performance.
Q. WHAT IS YOUR OUTLOOK?
A. We believe that tax-equivalent yields offered by municipal bonds in today's
markets are extremely compelling. In some cases, municipal bond yields are
equal to or higher than yields on comparable-maturity, taxable U.S.
Treasuries. (Principal value and interest on Treasury securities are
guaranteed by the U.S. government if held to maturity.) Therefore, we feel
that municipal bonds have been a relatively stable, attractive alternative
to other fixed-income asset classes and they have offered investors an
opportunity to reallocate some of their current holdings after the
tremendous runup in the equity markets.

NOTES TO PERFORMANCE SUMMARY
Class A Share Performance Including Sales Charge takes into account the
deduction of the maximum 4.75% sales charge. Class B Share Performance
Including Sales Charge takes into account the deduction of the applicable
contingent deferred sales charge (CDSC), which declines over six years from 4%
to 0%. Class C Share Performance Including Sales Charge takes into account the
deduction of the 1% CDSC applicable to shares redeemed within 12 months.
Class A and C share performance include the performance of the Fund's Class B
shares for periods prior to their inception (blended performance). Class A
blended performance has been adjusted to take into account the initial sales
charge applicable to Class A shares rather than the CDSC applicable to Class B
shares. Class C blended performance has been adjusted to take into account the
lower CDSC applicable to Class C shares. These blended performance figures
have not been adjusted to take into account differences in class-specific
operating expenses. Because operating expenses for Class A shares are lower
than those of Class B shares, the blended Class A share performance is lower
than it would have been had Class A shares been offered for the entire period.
Because operating expenses of Class B and C shares are approximately the same,
the blended Class C performance is approximately the same as it would have
been had Class C shares been offered for the entire period.
All performance results reflect any applicable expense subsidies and waivers,
without which the results would have been less favorable. Subsidies and
waivers may be rescinded at any time. See the prospectus for details. All
results are historical and assume the reinvestment of dividends and capital
gains.
INVESTMENT RETURN AND PRINCIPAL VALUE WILL FLUCTUATE, AND SHARES, WHEN
REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST. MORE RECENT
RETURNS MAY BE MORE OR LESS THAN THOSE SHOWN. PAST PERFORMANCE IS NO GUARANTEE
OF FUTURE RESULTS.
A small portion of income may be subject to state, federal, and/or alternative
minimum tax. Capital gains, if any, are subject to a capital gains tax. See
the prospectus for details.

NOTES TO FINANCIAL STATEMENTS
(1) Business and Organization
MFS Municipal Income Fund (the Fund) is a diversified 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 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.
Investment Valuations - Debt securities (other than short-term obligations
which mature in 60 days or less), including listed issues, are valued on the
basis of valuations furnished by dealers or by a pricing service with
consideration to 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, without exclusive reliance upon
exchange or over-the-counter prices. Short-term obligations, which mature in
60 days or less, are valued at amortized cost, which approximates market
value. Futures contracts listed on commodities exchanges are reported at
market value using closing settlement prices. Securities for which there are
no such quotations or valuations are valued at fair value as determined in
good faith by or at the direction of the Trustees.
Futures Contracts - The Fund may enter into futures contracts for the delayed
delivery of securities or contracts based on financial indices at a fixed
price on a future date. In entering such contracts, the Fund is required to
deposit with the broker either in cash or securities an amount equal to a
certain percentage of the contract amount. Subsequent payments are made or
received by the Fund each day, depending on the daily fluctuations in the
value of the contract, and are recorded for financial statement purposes as
unrealized gains or losses by the Fund. The Fund's investment in futures
contracts is designed to hedge against anticipated future changes in interest
rates or securities prices. Investments in interest rate futures for purposes
other than hedging may be made to modify the duration of the portfolio without
incurring the additional transaction costs involved in buying and selling the
underlying securities. Should interest rates or securities prices move
unexpectedly, the Fund may not achieve the anticipated benefits of the futures
contracts and may realize a loss.
Indexed Securities - The Fund may invest in indexed securities whose value may
be linked to interest rates, commodities, indices, or other financial
indicators. Indexed securities are fixed-income securities whose proceeds at
maturity (principal-indexed securities) or interest rates (coupon-indexed
securities) rise and fall according to the change in one or more specified
underlying instruments. Indexed securities may be more volatile than the
underlying instrument itself.
Investment Transactions and Income - Investment transactions are recorded on
the trade date. Interest income is recorded on the accrual basis. All premium
and original issue discount is amortized or accreted for financial statement
and tax reporting purposes as required by federal income tax regulations.
Interest payments received in additional securities are recorded on the ex-
interest date in an amount equal to the value of the security on such date.
The Fund uses the effective interest method for reporting interest income on
payment-in-kind (PIK) bonds. 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, 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 calculated as a percentage of
the Fund's month end net assets. The fee is reduced according to an
arrangement that measures the value of cash deposited with the custodian by
the Fund. This amount is shown as a reduction of expenses on the Statement of
Operations.
Tax Matters and Distributions - The Fund's policy is to comply with the
provisions of the Internal Revenue Code (the Code) applicable to regulated
investment companies and to distribute to shareholders all of its net income,
including any net realized gain on investments. Accordingly, no provision for
federal income or excise tax is provided. Distributions paid by the Fund from
net interest received on tax-exempt municipal bonds are not includable by
shareholders as gross income for federal income tax purposes because the Fund
intends to meet certain requirements of the Code applicable to regulated
investment companies, which will enable each Fund to pay exempt-interest
dividends. The portion of such interest, if any, earned on private activity
bonds issued after August 7, 1986, may be considered a tax-preference item to
shareholders.
Distributions to shareholders are recorded on the ex-dividend date. The Fund
distinguishes between distributions on a tax basis and a financial reporting
basis and requires that only distributions in excess of tax basis earnings and
profits are reported in the financial statements as distributions from paid in
capital. Differences in the recognition or classification of income between
the financial statements and tax earnings and profits, which result in
temporary over-distributions for financial statement purposes, are classified
as distributions in excess of net investment income or net realized gains.
During the year ended March 31, 2000, $1,036 and $808 were reclassified to
accumulated net investment income and paid in capital, respectively, from
accumulated undistributed net realized gain on investments due to differences
between book and tax accounting. This change had no effect on the net assets
or net asset value per share.
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
advisory and administrative services and general office facilities. The
management fee is computed daily and paid monthly at an annual rate of 0.30%
of the average daily net assets and 6.43% of investment income. The investment
adviser has voluntarily agreed to waive a portion of its fee, which is
reflected as a reduction of expenses in the Statement of Operations.
Administrator - The Fund has an administrative services agreement with MFS to
provide the Fund with certain financial, legal, shareholder servicing,
compliance, and other administrative services. As a partial reimbursement for
the cost of providing these services, the Fund pays MFS an administrative fee
at the following annual percentages of the Fund's average daily net assets:
First $1 billion 0.0150%
Next $1 billion 0.0125%
Next $1 billion 0.0100%
In excess of $3 billion 0.0000%
Distributor - MFD, a wholly owned subsidiary of MFS, as distributor, received
$48,045 for the year ended March 31, 2000, as its portion of the sales charge
on sales of Class A shares of the Fund.
The Trustees have adopted a distribution plan for Class A, Class B, and Class
C shares pursuant to Rule 12b-1 of the Investment Company Act of 1940 as
follows:
The Fund's distribution plan provides that the Fund will pay MFD up to 0.35%
per annum of its average daily net assets attributable to Class A shares in
order that MFD may pay expenses on behalf of the Fund related to the
distribution and servicing of its shares. These expenses include a service fee
paid to each securities dealer that enters into a sales agreement with MFD of
up to 0.25% per annum of the Fund's average daily net assets which are
attributable to that securities dealer and a distribution fee to MFD of up to
0.10% per annum of the Fund's average daily net assets attributable to Class A
shares, commissions to dealers and payments to MFD wholesalers for sales at or
above a certain dollar level, and other such distribution-related expenses
that are approved by the Trustees. MFD retains the service fee for accounts
not attributable to a securities dealer, which amounted to $46,209 for the
year ended March 31, 2000. Fees incurred under the distribution plan during
the year ended March 31, 2000, were 0.25% of average daily net assets
attributable to Class A shares on an annualized basis. Payment of the 0.10%
per annum Class A distribution fee will be implemented on such date as the
Trustees of the Fund may determine.
The Fund's distribution plan provides that the Fund will pay MFD a
distribution fee of 0.75% per annum, and a service fee of up to 0.25% per
annum, of the Fund's average daily net assets attributable to Class B and
Class C shares. MFD will pay to securities dealers that enter into a sales
agreement with MFD all or a portion of the service fee attributable to Class B
and Class C shares, and will pay to such securities dealers all of the
distribution fee attributable to Class C shares. The service fee is intended
to be consideration for services rendered by the dealer with respect to Class
B and Class C shares. MFD retains the service fee for accounts not
attributable to a securities dealer, which amounted to $27,738 and $1,711 for
Class B and Class C shares, respectively, for the year ended March 31, 2000.
Fees incurred under the distribution plan during the year ended March 31,
2000, were 1.00% of average daily net assets attributable to both Class B and
Class C shares.
Certain Class A shares and Class C shares are subject to a contingent deferred
sales charge in the event of a shareholder redemption within 12 months
following purchase. A contingent deferred sales charge is imposed on
shareholder redemptions of Class B shares in the event of a shareholder
redemption within six years of purchase. MFD receives all contingent deferred
sales charges. Contingent deferred sales charges imposed during the year ended
March 31, 2000, were $237, $151,711, and $25,082 for Class A, Class B, and
Class C shares, respectively.
Shareholder Servicing Agent - MFSC, a wholly owned subsidiary of MFS, earns a
fee for its services as shareholder servicing agent. The fee is calculated as
a percentage of the Fund's average daily net assets at an effective annual
rate of 0.10%.
(4) Portfolio Securities
Purchases and sales of investments, other than short-term obligations,
aggregated $205,095,534 and $237,718,592, respectively.
The cost and unrealized appreciation or depreciation in value of the
investments owned by the Fund, as computed on a federal income tax basis, are
as follows:
Aggregate cost $325,443,676
------------
Gross unrealized appreciation $ 10,993,755
Gross unrealized depreciation (7,442,102)
------------
Net unrealized appreciation $ 3,551,653

(6) Line of Credit
The Fund and other affiliated funds participate in an $820 million unsecured
line of credit provided by a syndication of banks under a line of credit
agreement. Borrowings may be made to temporarily finance the repurchase of Fund
shares. Interest is charged to each fund, based on its borrowings, at a rate
equal to the bank's base rate. In addition, a commitment fee, based on the
average daily unused portion of the line of credit, is allocated among the
participating funds at the end of each quarter. The commitment fee allocated to
the Fund for the year ended March 31, 2000, was $2,529.
(7) Financial Instruments
The Fund trades financial instruments with off-balance-sheet risk in the
normal course of its investing activities in order to manage exposure to
market risks such as interest rates. These financial instruments include
future contracts. The notional or contractual amounts of these instruments
represent the investment the Fund has in particular classes of financial
instruments and does not necessarily represent the amounts potentially subject
to risk. The measurement of the risks associated with these instruments is
meaningful only when all related and offsetting transactions
are considered.

without registration under the Securities Act of 1933. The Fund does not have

INDEPENDENT AUDITORS' REPORT
To the Trustees and Shareholders of MFS Municipal Income Fund:
We have audited the accompanying statement of assets and liabilities,
including the portfolio of investments, of MFS Municipal Income Fund (one of
the series constituting MFS Municipal Series Trust) as of March 31, 2000, the
related statement of operations for the year then ended, the statement of
changes in net assets for the years ended March 31, 2000 and 1999, and the
financial highlights for each of the years in the five-year period ended March
31, 2000. These financial statements and financial highlights are the
responsibility of the Trust's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.
We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material
misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. Our
procedures included confirmation of the securities owned at March 31, 2000 by
correspondence with the custodian and brokers; where replies were not received
from brokers, we performed other auditing procedures. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.
In our opinion, such financial statements and financial highlights present
fairly, in all material respects, the financial position of MFS Municipal
Income Fund at March 31, 2000, the results of its operations, the changes in
its net assets, and its financial highlights for the respective stated periods
in conformity with accounting principles generally accepted in the United
States of America.
